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.
