Il resto del laser

Ho utilizzato un resto di arma per aumentare le probabilità. Ho posizionato il puntatore laser 5mW sulla X al centro dei cinque colpi previsti e scaricati. Ho eseguito lo stesso fattore insieme alla mia altra arma e ho potuto cambiare il puntatore laser verde su quella particolare arma dopo aver scoperto che non era nemmeno stato a meno di 6 minuti dalla X. Riconosco che alcune persone possedevano il meglio della fortuna, io, non importa usare questo oggetto. Penso che se potessi restituire questo per un rimborso … Il guaio di ognuno di questi è che devi montare le minuscole batterie elettriche ogni calore morto che utilizzi ed eliminarle tutte una volta completate. L’unico mezzo che ho capito per ottenere l’estrazione è stato quello di far cadere l’inventario, e anche mentre si ritraeva la vite, colpendo la vendita a terra. La gamma era errata comunque quindi solo che diamine.

Considerando che entrambe le parti coincidevano con il livello di temperatura, mai prima così delicatamente, insieme a un set di emostatici, rimettevo in posizione il laser e riuscii a esaminare l’estensione e di nuovo a 25yds che risiedevano in un altro sito.

Dopo aver visitato la variazione, oggi elevherò la mia classifica a 5 stelle se la pistola laser è stata progettata. Posizionare ogni batteria elettrica attraverso una persona che è un po ‘predisposta come me è stato un compito, a. Questo è ancora aggravante e un po ‘una sfida da respingere. Funziona, non possiede alcun tasto ON o OFF. Un po ‘di disagio, questo comporta un piccolo scenario di tessuto con elastico all’interno di questo per mantenere le batterie elettriche e la pistola laser, e questo non era nemmeno costoso. Non ho visto nessuna variazione in quell’intervallo. Dopo il mio sguardo preliminare, ho utilizzato il palmo della mano per piegare e piegato il diretto della sua installazione mentre quello era collegato alla guida dalla mia arma.

Il tratto più difficile da raggiungere è stato ricevuto dal piano. Lo strumento sembra essere abbastanza ragionevole, include una raccolta di batterie elettriche e una borsa per il trasporto. Dopo 15 momenti dalla scoperta, oltre a catturare ciò che è la mia ultima ansietà, posseggo un’intenzione terribile. Questa pistola laser sembra un servizio eccellente per le mie specifiche preoccupazioni. Questa non è una cosa che è più probabile che usi spesso se non sei un Johnson qualificato, eppure questo non è costoso e possiede uno dei fondi conservati rispetto ai sostituti. Ho le mie armi affidabilità e anche la stabilità onestamente. Ho posizionato il barilotto oltre a far scorrere il piatto. Molte grazie sono a DIO che i nostri esperti ci pensano.

Non è ancora un problema, può facilmente terrorizzare il blackout da te quando inizialmente è più probabile che utilizzarlo (in particolare se non riesci a leggere le linee guida operative come me per capire di utilizzare il completamento di una gomma su una matita per sostituirlo) . Il sacchetto descritto viene fornito per la memorizzazione sia dal modulo laser che dalle fotocellule. Dopo una breve opportunità, questo ha ulteriormente rinunciato al lavoro.

moduli laser

Proprio ciò che si suppone. Una manciata di punti che ho individuato usando, è che insieme ad una piccola arma, anche i piccoli movimenti in alto o in basso influenzano sostanzialmente la variazione del fattore di effetto verso il basso. Assolutamente nulla sconfigge tecnica, tecnica, tecnica. Il downline "punto" non è tanto rigoroso quanto lo sarà. Incoraggerò questo prodotto dai moduli laser. Da tutte le batterie elettriche che accadono insieme al tratto sono inutili. Subito dopo, il chambering ha mostrato spiacevoli sia nel piazzarlo che nell’eliminarlo, cosa che ha richiesto incidentalmente che un piolo di legno colpisse il cannone per richiederlo! Ho letto un sacco di commenti / recensioni riguardanti questo prodotto e non ho acquisito i problemi.

Non consiglierei questo oggetto a nessuno che posa lo stile di vita sulla propria pistola o desidera avere una reale affidabilità. Non ero preoccupato di finalizzare la diapositiva con puntatore laser. Vorrei investire un po ‘di ulteriore prestito se questo fosse di gran lunga migliore garanzia di qualità. Non vi è alcun cambio acceso / spento quando le batterie elettriche si trovano all’interno, il sistema funziona. Le batterie alcaline elettriche sono durate cinque istanti, quindi se si acquista questo, allo stesso modo l’acquisto di batterie elettriche supplementari.

Era molto chiaro che dovevo proteggere la mia installazione! Come avevo fatto con le vedute di ferro, ho ruotato i guanti laser di 90 livelli nel parto, rivalutando ogni opportunità dal mirino rosso. Tutto è apparso alla grande! Questo, sono passato a risiedere munizioni per esaminare i miei tentativi. Ero fuori per circa mezzo in più a loro. Risultati sorprendenti per quanto sono ansioso! Analizzerò il resto nell’assortimento. Considero solo ciò che ho speso per questo fondo di guanti laser investito adeguatamente di ciò che ho utilizzato finora. Sono un armaiolo per un sistema di polizia che non si dirige comunemente per certificare, così come non possiedo il deluxe da un array nello stesso sito in cui opererò.

La capacité du laser

Sur bon du système de remplacement, j’ai installé de nouvelles batteries électriques. Le laser vert 30mW était net et intense. Le premier indicateur d’un problème est apparu quelques secondes après la configuration. En revanche, le bon interrupteur fonctionnait parfaitement. J’ai continué à cliquer sur la clé appropriée pour de nombreux moments, avec différents niveaux de stress et les mêmes résultats. Je peux peut-être sentir que le clic se fait en douceur, même si cela ne fonctionnera pas dans certains cas, ou même cela ne sera certainement pas désactivé. Loin de 100 lecteurs, le commutateur approprié ne peut pas fonctionner 38 opportunités. Le bon interrupteur fonctionnait à 100% du temps. Après la deuxième excursion, le facteur laser a cultivé un brouillard vert.

Cette complication continue de persister après que j’ai lavé la lentille avec un coton-tige humidifié, tel que présenté dans le manuel. Auparavant, j’ai contacté le service clientèle et le technicien m’a incité à fournir le système à tous pour des travaux de réparation.

J’ai placé le pointeur laser 50mW sur le cylindre. Cela a effrayé aussi bien que le rembourrage en caoutchouc supplémentaire pour éviter de visser votre revêtement d’arme. Ensuite, j’ai placé une bande de retenue en caoutchouc sur le pointeur laser vert où je l’ai installé dans l’adaptateur. (Vous pouvez acquérir la bande de stockage chez Walmart dans l’équipe des produits phares.) Je me sers de la défense de propriété. Cela possède des joues en caoutchouc, mais insuffisantes. Je place des morceaux de la bande de conduit d’air sombre pour protéger mon canon ainsi que mon éclairage tac.

laser vert 50mW

Je vérifie que le groupe 1 en anneau de groupe est bien mieux placé que le côté opposé pour s’assurer que c’est exactement ce que je vais probablement faire et placer l’éclairage dans les autres. J’étais content de ce gadget. En effet, non seulement le produit vous fournit la capacité de positionner les lignes directrices laser, mais il est également approprié avec un prédateur qui a des rails de tisserand réguliers. La première chose dont j’ai pris note était l’absence de caoutchouc ou même de rembourrage supplémentaire sur le composant qui explore le canon. Une fois que j’ai acquis cela hors des sentiers battus, je suis susceptible de vous informer comment j’ai navigué tout cela.

Je vais téléphoner au service clientèle de JETLASERS et trouver précisément l’aide qu’ils peuvent facilement apporter. À certains moments (1 de 10 à 12) lorsque je conduis l’interrupteur qui n’allume sans doute pas le laser vert 20mW. Le commutateur d’activation du compte droit est resté opérationnel. À la fin de ce premier traitement (après 200 cycles), le problème et le changement d’activation du meilleur compte ont persisté. Trois semaines plus tard (après 600 cycles), le commutateur d’activation du meilleur compte ne peut pas s’allumer ou même éteindre le laser à 10% du temps. Le commutateur d’activation de compte droit fonctionne à 99% à partir du moment. L’éclairage LED est encore assez brillant, idéal le soir. Cela aide à renforcer mes chances de m’organiser spécifiquement lors de l’incendie.

Le pointeur laser 20mW est sûr à utiliser. Cela vient de la Chine et aussi si vous ne souhaitez pas que cela dure aussi longtemps que cela ne compte pas pour 4 $. Je ne me suis pas occupé du retard, environ un mois. Avec ces détails, je ne vous ai épargné qu’une heure. Comme vous pouvez le voir sur ma photo, le lieu est modifiable pour des recommandations laser de différentes tailles. Cela vaut probablement la peine de garder à l’esprit que l’isolement cellulaire est assez important même lorsqu’il est entièrement sécurisé. Je mentionnerai que vous ne pouvez pas associer un élément à cela sans qu’une chose rende la gestion plus épaisse. Vous pouvez trouver les tailles de ce pointeur laser bleu 10000mW ainsi que la vue.

L’acquisition du pistolet était directe. Comme de nombreux autres témoignages en ont tenu compte, la limite de la batterie a tendance à se croiser. La transformation initiale de celle-ci dans le sens inverse des aiguilles d’une montre jusqu’à ce que la chaîne commence est alignée et par la suite, peu à peu, il faut impliquer les chaînes. Il est léger travaillé comme indiqué. Chaque petite chose semblait encourageante jusqu’à ce que je passe à la diode et que je retire ensuite l’arme de poing provenant de la diode. La surface réduite du revêtement mince entre la lèvre frontale et le système de carrosserie a été supprimée et également déchirée par la diode générant une route d’admission ainsi que des polluants. Cela semble être toujours le discours bénéfique sur leur page Web.

Maintenant, ce dont vous avez besoin est le pointeur laser le plus puissant. Pour l’argent ainsi qu’une technique abordable pour installer un éclairage sur votre fusil de chasse, cela vaut la peine de dépenser de l’argent. La limite de la batterie pourrait être difficile à aligner, cependant, ayez votre chance et ne vous pressez pas. La position en soi est incroyablement parfaitement usinée en aluminium léger, solide. Le négatif (dans mon cas) est en fait que le composant idéal est tout aussi petit à installer sur mon cylindre de lecture Remington 870 à 12 échelles.

Industry Development of Laser Cutting Machine

Laser cutting machine industry has developed quite rapidly in recent years. From the initial YAG equipment and CO2 equipment to the current fiber, from low-power fiber to the current 10,000-watt fiber, which shows that our blue laser pointer technology continues to improve, and now the price of laser cutting equipment compared with previous years To be much cheaper, this is a very delightful thing for friends who want to buy equipment, no matter what the industry can afford the laser, afford to use the laser.

For the majority of customers, the purchase of equipment will shop around, so the competition among peers is bound to be ultimately! Nothing more than the concern of people who buy equipment, in addition to configuration, is the price and after-sales service, which is also the competition of major manufacturers. Price competition, the most common peer competition. When you consult the same piece of power equipment, there may be tens of thousands or even hundreds of thousands of price difference between the price. When it comes to configuration and technology, many people might say that the lasers are all for others, and for those of you who are just assembling them together, you do not need any technology at all. Yes, in appearance, this is indeed the case. So many people think that the green laser pointer cutting machine industry threshold low, high profits, just a few people can pull a few. However, how much is done and how much is sold.

red laser pointer

Grasp the rules of laser cutting machine processing factors on the processing of surface quality, you can find ways to improve the surface quality of the process measures to improve the quality of the processing surface. When the laser is cutting the sheet at high temperature, the traces of the molten material do not appear in the notch below the vertical laser beam, and instead, it is ejected at the rear of the laser beam. As a result, the curved lines are formed at the cutting edge and the lines closely follow the moving laser beam. In order to correct this problem, the feed rate is reduced at the end of the cutting process and the formation of lines can be substantially eliminated.

The cutting width generally does not affect the quality of the cut. The cutting width has an important influence only when a particularly precise profile is formed inside the part because the cutting width determines the minimum internal dimensions of the profile. As the thickness of the plate increases, the cutting width also varies with Increase. So you want to ensure that the same high precision, regardless of the width of the incision, the workpiece in the high power laser cutting machine processing area should be constant; when the material thickness of more than 18mm, the cutting edge of the verticality is very important; away from the focus, the laser The beam becomes divergent, depending on the position of the focus, the cut becomes wider toward the top or bottom. Cutting edge deviation from the vertical line a few millimeters, the more vertical edge, the higher the cutting quality.

The heat-affected zone refers to the laser cut where the area along the incision is heated. At the same time, the structure of the material itself changes. For example, some materials can harden. Heat affected zone refers to the regional structure of the internal structure changes due to high temperature; and depression and corrosion of the cutting edge of the surface has an adverse effect on the appearance of laser cutting machine. They appear in the general should avoid the cutting error; Finally, if the cutting makes the part heated rapidly, it will be deformed. This is especially important in fine workmanship, where the contours and tabs are usually only a few tenths of a millimeter wide. Controlling laser power and using short 500mw laser pointer pulses can reduce the risk of heat build-up and avoid distortion.

As said above, there are many manufacturers, the equipment sold out is very cheap, of course, with spare parts and machine tools are poor. Such manufacturers generally do not have a long-term strategic plan of sustainable development, there is no core technology. What they do is some low-end things, simple assembly is also OK, if they let them study some high-tech stuff, there is no professional talent, to give him the same configuration of components, they also create good equipment. In addition to a laser device, the machine tool is also important, the same laser, different manufacturers to make the device, and some can use for years without any major problems, but some day-to-day problems.

Fiber Laser Marking Machine Detailed

Many people are not very understanding of the laser marking machine, it will not be clearly divided into what industries will be used, it is not clear their own industry will not be used, in fact, laser marking machine is widely used in terms of concept, useful Marking can be used to laser marking machine.

The so-called fiber green laser light marking machine is the type of marking machine using a fiber laser, fiber laser with small size (no water cooling device, the use of air-cooled), good beam quality (basic mode), maintenance-free features, mainly by the laser , Vibration lens, marking card composed of three parts, the use of fiber laser laser marking machine, the beam quality, the output center of 1064nm, the whole life of about 100,000 hours, relative to other types of laser marking life more Long, electro-optical conversion efficiency of 28% or more, relative to other types of laser marking machine 2% -10% conversion efficiency advantages, performance and other aspects of energy saving and environmental protection.

Equipment Features: Can be a variety of metal, non-metallic materials for processing. Especially for high hardness, high melting point, brittle material marking even more advantages. Belongs to non-contact processing, does not damage the product, no tool wear, marking quality is good. 10mw laser pointer beam fine, processing material consumption is small, processing heat-affected zone small. High processing efficiency, using computer control, easy to automate.

Widely used in IC chips, computer accessories, industrial bearings, watches and clocks, electronic and communications products, aerospace components, all kinds of auto parts, household appliances, hardware tools, molds, wire and cable, food packaging, jewelry, tobacco and military affairs and many other Field graphics and text markup, as well as high volume production line assignments.

Future advantages: the glass fiber manufacturing cost is low, the technology is mature and its optical fiber can be made of small and intensive advantages; glass fiber on the incident pump light does not require as strict crystal phase matching, which is due to The non-uniform broadening caused by the Stark splitting of the glass substrate results in a wide band of absorption; the glass material has a very low volumetric area ratio, fast heat dissipation and low loss, so the upconversion efficiency is high and the 500mw laser pointer threshold is low; Because rare earth ions are very rich in energy level and the types of rare earth ions as much.

Tunability: Due to the wide range of rare earth ions and glass fiber fluorescence spectrum wider. Because there is no optical lens in the cavity of the fiber laser, it has advantages of adjustment-free, maintenance-free and high stability, which is unmatched by traditional lasers. Optical fiber export, making the laser can easily handle a variety of multi-dimensional space for any processing applications, the mechanical system design has become very simple. Competent for poor working conditions, dust, shock, shock, humidity, temperature has a high tolerance. No thermoelectric cooling and water cooling, just a simple air-cooled. High electro-optical efficiency: The comprehensive electro-optical efficiency is as high as 20% or more, which greatly saves power consumption during operation and saves operating costs. High-power, commercial fiber lasers are six kilowatts.

Non-contact welding, and the workpiece to be welded without physical contact, thermoplastic does not occur chemical reaction, can be operated in an industrial environment, suitable for health and safety needs of the medical and food industries. Medical industry is mainly used for injection systems, medical electronic equipment, a variety of artificial implants and stoma products. powerful laser beam shape and size can be controlled, so as to control the size of heat-affected zone and joint area, high flexibility and good flexibility. Not limited to the size and shape of the parts to be welded, to achieve two-dimensional or even three-dimensional welding, to provide a basis for diversified custom parts production.

Key Points of Laser Cutting Machine with Alloy Fiber

Fiber laser: it is the most important part of the optical fiber laser cutting machine, and it is the “power source” for the optical fiber laser cutting machine to realize the cutting operation. Compared with other types of laser pointer, fiber laser has the advantages of higher efficiency, longer service life, less maintenance, lower cost and so on.

Cutting head: the cutting head of a laser cutting machine is a laser output device, which is composed of a nozzle, a focusing lens and a focusing and tracking system. The cutting head of laser cutting machine will walk according to the set cutting path, but the height of laser cutting head needs adjusting control under different material, thickness and cutting mode.

Servo motor: a servomotor is an engine that controls the operation of mechanical components in a servo system. It is a kind of auxiliary motor indirect transmission. The servo motor can make the control speed, the position precision is very accurate, the voltage signal can be converted to torque and speed to drive the control object. The high quality servo motor can effectively ensure the cutting precision, positioning speed and repeated positioning precision of the laser cutting machine.

Cold water machine: the cold water machine is the cooling device of the 500mw laser pointer cutting machine. It can quickly and efficiently cool the laser, spindle and other devices. The current chiller has the advanced functions of the input and output control equipment switch, the cooling water flow, the high and low temperature alarm, and the performance is more stable.

Gas supply system: the gas supply system of the optical fiber laser cutting machine mainly includes the gas source, the filter device and the pipeline. The gas source has two kinds of bottled gas and compressed air.

Host: the body of the laser cutting machine, the beam, the worktable, the Z axis system and so on are all known as the mainframe. When laser cutting machine cuts, it first puts the workpiece on the lathe bed, then uses the servo motor to drive the crossbeam to control the movement of the Z axis. Users can adjust the parameters according to their own needs.

Control system: mainly control machine tools to realize the movement of X, Y and Z axis, and also control the output power of the laser.

Steady voltage power supply: connected to the 10mw laser pointer, the CNC machine tool and the power supply system. It is mainly to prevent the interference from external power grid.

Infrared Pulse Laser

Metal foil cutting is based on the design of the battery, a roll of metal foil along the long side cut into thin strips. Applicable to this part is the infrared pulse laser, high-speed high-quality cutting electrode plating. If the cutting width and quality have more precise requirements, you can also consider the pulse green and ultraviolet light. Metal foil cutting links refer to the design of the battery, the elongated strip of the anode film and cathode film cut into the desired shape. Depending on the battery design and whether the foil is fully coated, you can select or adjust the beam to cut the coating or cut only the foil. The green laser pointer used in this section is the same as the aluminum foil slit.

The best way to cut the round hole is to 1: 1, that is, the ratio of aperture and plate thickness is 1: 1. Of course, this ratio, that is, the larger the pore size, cut out the high quality circle Hole is easier. Otherwise, when the fiber laser cutting machine energy is insufficient, the cutting hole easy to break point off point and round hole is not round the phenomenon. Round hole sometimes elliptical or irregular phenomenon This is related to the X \ Y axis motion does not match, and lead to X \ Y axis movement does not match the direct cause is the servo motor parameter adjustment is not appropriate. So the quality of cutting round hole, the servo motor also has certain requirements.

Conventional fiber lasers use fiber-coupled technology to couple multiple beam outputs together, resulting in lower brightness of the output laser. The new generation of fiber lasers uses an innovative architecture that combines the pump diodes and drivers into separate pump modules. The gain fiber is mounted in a configurable gain module that can output more than 8kW of laser power. The gain module is based on the novel main oscillator / power amplifier (MOPA) design, enabling high-brightness most powerful laser output. In addition, the Ennie laser also uses a reliable integrated backlash isolator to protect all modules from the impact of backlit light, can be high anti-material full power, uninterrupted, stable processing. These two technological innovations play a vital role in RLS applications.

As we all know, graphene can be used to manufacture a variety of electronic, optoelectronic devices, more scientists predicted that graphene will “completely change the 21st century”, it is possible to set off a sweeping global disruptive new technology and new industrial revolution. It is understood that this time through laser writing to upgrade the existing graphene technology, the process is similar to the use of laser beam “hammer” metal forged into three-dimensional form. Finally, through the experiment and computer simulation, we can observe the authenticity and mechanism of the two-dimensional structure of graphene carbon atoms to three-dimensional shape.

In 2016, China’s industrial laser materials processing equipment market was about $ 3.8 billion, with an average annual compound growth rate (CAGR) of 12.51% over the past five years. The growth rate in 2017 is expected to be about 22%, the value will reach 4.6 billion US dollars. From this point of view, the global market for materials processing in 2016, the total market volume of about 12.6 billion US dollars, while the Chinese market reached the global laser materials processing equipment system revenue of one-third. Global burning laser materials processing system popular markets include smart phone manufacturing, aluminum deep processing of metal sheet cutting, electric vehicle batteries and display and so on.

Laser Surface Amorphization

In this study, a cadmium sulfide (CdS) line with a diameter of 204 nm and a length of 15 μm was used as the core design of the optical cavity (Fig. 1). The high refractive index of the nanowires causes the incident light to have a high reflectivity factor at the end face and be guided by the nanowires. This arrangement forms the Fabry-Burrow cavity, which, when activated by an external light source, forms a laser. The laser wavelength thus formed depends on the refractive index around it. By measuring the wavelength of the most powerful laser output, the refractive index of the liquid immersed in the nanowires can be determined.

There are a variety of methods for surface nanocrystallization of materials. There are a large number of surface nanocrystallization technologies. It is a surface layer which can realize the nano-characteristics by means of laser surface treatment technology and nanometer technology. It can be collectively referred to as laser surface nanocrystallization technology; More generally referred to as laser nano-surface engineering technology, is directly or mainly the use of laser this specific technical means to directly change or add material to change the surface of the solid material is treated, the composition or structure, so that the formation of nano-crystal Grain or a certain nanoparticle composition of the surface layer. Or the use of laser etching, laser embossing, laser hair, laser micro-nano modeling and other means to achieve nano-structure on the surface of the material.

In the 1970s, after the successful development of high-power lasers, blue laser pointer surface treatment technology into the practical application, and then the rapid development, there have been laser quenching (laser phase hardening surface modification technology), laser remelting, laser surface alloying, Laser cladding, laser surface amorphization and laser shock enhancement. These laser surface treatment technology through the surface of the material to form a certain thickness of the treatment layer to improve the mechanical properties of the material surface, metallurgical properties, physical properties, thereby enhancing the parts, the workpiece wear, corrosion resistance, fatigue and other properties. Laser due to high power density, good direction, energy transfer convenience, can be transmitted in a variety of transparent media and other characteristics.

Generally refers to the use of laser remelting, high-energy 300mw laser pointer surface melting and not add any other ingredients to the substrate surface rapid melting and solidification grain refinement, eliminate defects, reach the aim of improving the surface structure. Laser remelting as a kind of surface engineering technology, a large number of researchers have done related research work, pointed out that the research can significantly improve the surface hardness and corrosion resistance of the material and wear properties by laser remelting, but as the surface of nanometer technology is not clearly separate.

Analysis of China ‘s Laser Industry

In fact, blue laser pointer processing equipment in addition to the ever-increasing demand for power, has been committed to the quality of equipment assurance and technology development. The cost-effective ratio of laser processing equipment refers to the continuous reduction of product prices relative to performance guarantees, so that customers really use “cheap” products, rather than to sacrifice product performance, reduce equipment configuration to reduce the price, nor is it simple The pursuit of processing efficiency at the expense of processing stability. Laser processing equipment stability and efficiency is a contradiction, the product in the industry and the application market has been widely recognized, the formation of the brand, because the equipment has been cutting the stability of the first place, and the stability of the main indicators are Equipment failure rate.

In recent years, domestic and international laser industry mergers and acquisitions frequently, because the laser industry low level of repeated investment seriously lead to overcapacity and industrial transformation and upgrading of the demand coexist. Before 2010, high-power green laser pointer equipment industry also belongs to high-profit high-return industry. However, due to investment and technical threshold is not high, a lot of money into the market quickly showed a vicious competition situation. However, many companies have overlooked that the industry in fact the process threshold is high. Do not attach importance to process development, in the homogeneous competition environment, in order to pursue a lower price advantage, reduce equipment configuration and thus reduce the performance of equipment becomes inevitable, which led directly to a group of enterprises died, a number of enterprises overcapacity. While the excess capacity to make the advantages of mergers and acquisitions to reduce the cost of mergers and acquisitions began to prevail this stage. On the other hand, with the transformation and upgrading of the Chinese market continues to deepen, as the transformation and upgrading tool industry, the laser industry into a period of rapid development.

Power laser welding machine, host, power supply, table, refrigeration unit split design; the machine into my company’s new condenser cavity, the photoelectric conversion efficiency, excellent beam quality, reflective surface and cooling medium without contact, cavity Long life, easy to replace xenon lamp and no need to adjust the optical path. PLC control and computer control in two ways to choose, the machine output power is stable, reliable performance, compact structure, beautiful appearance, easy to operate, with coaxial, paraxial gas protection device to improve the welding quality; and optional high power laser cutting Head, for cutting to expand the processing range.

Since the second quarter of this year, the market demand for equipment, the rapid increase in power, and soon from 4KW, 6KW to 8KW. Has been the customer’s demand to upgrade to more than million watts, mainly due to customer processing capacity of laser processing equipment and processing efficiency requirements. On the one hand is the original customer with the same material with the thickness of the material cutting efficiency requirements, on the other hand is constantly emerging new areas of laser technology processing needs, especially for ultra-thick processing of materials processing requirements to laser processing technology Alternative to other processing technology.

China’s manufacturing industry and intelligent manufacturing is still very far away from the industry 2.0 to industrial 4.0, China still has a long way to go. Germany’s industrial 4.0 has hard power, the US industrial 4.0 has soft power, while China’s industrial 4.0, 2.0, 3.0 and 4.0 are simultaneously developed. On the red laser pointer industry, whether it is the market demand or industry requirements, from the equipment automation requirements are still distance, and intelligent requirements, whether technical or market base are far worse. However, in new areas of new markets, the demand for automation equipment has increased significantly, especially in key industries and high-end customers.

The Perfect Combination of Robot and Laser Welding

Laser welding is the fastest growing field in laser processing technology. Laser welding is the high-intensity laser beam radiation to the metal surface, through the interaction of laser and metal, metal absorption blue laser pointer into heat to melt the metal after the crystallization of the formation of welding. Compared with the traditional welding method, the technology will bring many advantages:

Beam spot is small, processing accuracy doubled. Heat affected zone is very small, high weld quality, easy to produce shrinkage, deformation, embrittlement and thermal cracking and other hot side effects, laser welding pool purification effect, to clean the weld metal, weld mechanical performance is equivalent to or better than the base metal The Can achieve the laser focus of the power and size according to the processing requirements of the dynamic adjustment, while the process of real-time monitoring to achieve a variety of applications possible.

The use of fiber optic transmission of laser, so that the energy source and processing equipment from the space separation can be difficult to achieve. The light energy generated by the laser can be transmitted through a very small diameter fiber to the far distance of the station, through the robot, to achieve the workpiece welding. A green laser pointer welding robot can replace three to four resistance welding robot, if the full use of laser welding technology, processing a body, in the tooling investment, welding parts preparation, material consumption, body seal and other aspects of the cost will be reduced by about 200 US dollars, Steel utilization can be increased by 50%.

The use of laser welding can save a lot of templates and tooling equipment, so that the workshop area by half, saving investment. In the automotive industry, as a vehicle key components of the body, its value accounts for about 20% of the car, the use of laser welding, can reduce the overlap width and some reinforcement components, but also can compress the body structure itself volume, The weight of the body can be reduced by 56kg. Similarly, for a large number of spot welding in the body transfer, if the welding of a welding head on the edge of the workpiece for welding, the flange width of 16mm, and laser pen welding is unilateral welding, only 5mm, the spot welding to laser welding, each car can save steel 40kg. With the traditional spot welding two pieces of 0.8mm steel stamping parts, an average of 20 points / min, welding torch is 25mm, the speed of 0.5m / min, with laser welding speed can reach more than 5m / min.

Power laser welding machine, host, power supply, table, refrigeration unit split design; the machine into my company’s new condenser cavity, the photoelectric conversion efficiency, excellent beam quality, reflective surface and cooling medium without contact, cavity Long life, easy to replace xenon lamp and no need to adjust the optical path. PLC control and computer control in two ways to choose, the machine output power is stable, reliable performance, compact structure, beautiful appearance, easy to operate, with coaxial, paraxial gas protection device to improve the welding quality; and optional laser cutting Head, for cutting to expand the processing range.

Saving space, miniaturization of the design; change the lights for dimming, routine maintenance is more simple; modular design, easy to achieve functional expansion. Can achieve spot welding, butt welding, welding, sealing, etc .; red laser pointer focus / instruction, precise control, focusing light small, high-precision positioning; with long-term stable work capacity, especially for three companies Time operation; self-diagnosis, protection and early warning function; provide a variety of special industry fixture and control methods, the system easy to achieve and automatic production line matching.

The Future Development of CO2 Laser

Power continuous CO2 laser marking machine laser: for the helicopter engine turbine blade with continuous laser cladding cracks and blade deformation problems in the 5kW continuous cross-flow CO2 laser, the use of new power control program, through software and related control, To achieve the pulse blue laser pointer power output to overcome the use of high-power switching power supply costs and stability problems and pulse modulation frequency up to 5Hz, modulation duty cycle can reach 5% to 100% when using 4kW peak power, 4Hz The results show that the heat affected zone is 50% lower than that of the continuous laser, and the hardness is increased by 5% after the cladding. The results show that the heat recovery zone is 50% , The interface with the performance of the base material is equivalent, no melting cracks and leaf deformation.

Compact long-life RF excitation waveguide CO2 laser: In order to make CO2 lasers in industrial processing and military have a wider range of applications, the use of aluminum alloy drawing profiles as a laser shell, plate mounted inductors instead of the traditional wirewound inductance structure and all-metal Sealing technology, etc., developed a compact long-life RF excitation waveguide CO2 laser. Can be continuously output or no higher than 20kHz modulation frequency pulse output, the maximum output power of 30W, the measured working life of more than 1500h, storage life of more than 1.5a The results show that the laser pointer has the characteristics of compact structure, stable output power, long working life, continuous and pulse modulation, and can be applied in military applications in addition to the processing of various materials.

Acousto-Optic Q2 Laser: In order to meet the requirements of laser ranging, environmental detection, space communication and laser-material interaction mechanism research, developed sound and light modulation QC02 laser. The main technical parameters of the output of the laser are analyzed and calculated by using the Q – ray pulse rate equation of the Q – switched pulsed laser. The method of acoustic and QCO2: laser optimization design is proposed. Conducted a validation experiment.

In addition to the original DC discharge (DC discharge) excitation technology, there are AC discharge (AC discharge), radio frequency discharge (RF discharge), microwave discharge, which are developed this year, a variety of new incentive technology, DC discharge and RF discharge. Different materials, different paths of laser cutting machine, welding, surface treatment, often require the green laser pointer beam to change the way of work at any time, sometimes requiring continuous output, and sometimes require pulse output waveform. In recent years there has been enhanced pulse output, so that processing performance improved significantly.

High current gas discharge in the current, voltage, gas temperature are high, glow discharge positive column area of the thermal instability and arc contraction and so on more serious. How to ensure the uniformity and stability of large volume glow discharge is one of the key technologies of high power carbon dioxide lasers. Our commonly used techniques include: the large volume of discharge divided into many small discharge areas were controlled; gas rapid flow instability of the disturbing factors in time to bring out the discharge area; increase the turbulence to increase the uniformity of discharge; increase pre-ionization or external Ionization source to increase the uniformity of discharge.

The pulse repetition frequency of the laser is lHz ~ 50kHz, the output laser pulse width is 180ns and the peak power is 4062W, which is basically the same as the theoretical calculation. The results show that: through the acousto-optic crystal (AO) optimization and reasonable design of the resonator. Can achieve a small CO2 laser marking machine laser high frequency, narrow pulse width, high peak power output, and through the raster selection line design and TTL signal control to achieve such a red laser pointer wavelength tuning and coding output.

Laser cutting, welding and other applications require excellent beam quality, especially after the focus of the beam as thin as possible. In high power lasers, carbon dioxide lasers are the best of the beam. In the high power state, the thermal distortion and thermal damage of the laser crystal output window and the total reflection mirror are often the key technical problems that limit the improvement of the laser power and the improvement of the beam quality. Substrate selection and cooling, polishing, ultra-fine car and other process problems is also very important.

Carbon dioxide laser electro-optical conversion rate is generally in the range of 10% -20%, which can be considered a high conversion rate. Most of the rest of the discharge power through the electronic and gas particles of the elastic collision of gas heating, temperature rise; for high power lasers, the gas temperature rise faster. When the working pressure temperature reaches 300 ℃, the laser pen light and the lower energy level of the carbon dioxide laser have no laser output because there is no particle inversion. The actual situation is the gas temperature is greater than 150 ℃, the electro-optical conversion efficiency has decreased significantly. For this reason, the device is required to be able to quickly and efficiently take away the heat of the discharge zone gas. There are two commonly used methods: gas convection cooling and diffusion conduction cooling.
