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.
