Laser marking machine principle: the laser generator generates a high-energy continuous laser beam, focused laser action on the printing material, by controlling the path of the laser on the surface of the workpiece, instantly melting or even evaporating the surface material, and finally forming the desired graphic mark. greatly improved the structure of the equipment: optical system with sealed structure, optical path browsing and focus marking, more beautiful appearance, more convenient operation; equipment equipped with the latest external water cooling system, low operating noise, high precision temperature regulation, to provide a reliable guarantee for the long-term operation of the equipment. some models of XD / Fengrui series can also be used to match the automatic production line and automated assembly line of the machine. The most common laser marking machine is mainly CO2 laser engraving machine and its YAG laser engraving machine, and then the YAG laser marking machine is gradually replaced by the semiconductor laser engraving machine, which becomes the model with the largest ownership in the laser engraving machine market. In addition, there are high-end end-pump laser marking machine, fiber laser marking machine, ultraviolet laser marking machine and so on. With the development of science and technology, fiber laser marking machine in the electronics industry is more and more accepted, its characteristics are very obvious: comprehensive design, small size, low power consumption, long life, high efficiency, free maintenance, high laser quality, detailed light point, no consumables. The characteristics of laser engraving are non-contact processing, can be marked on any shaped surface, the workpiece will not be deformed, generate thermal stress, suitable for marking metal, plastic, glass, porcelain, wood, leather and other materials. Laser can mark almost all parts, marking wear-resistant, the production process is easy to complete automation, marking parts become smaller. Laser marking machine uses scanning method for marking, shooting laser into two reflectors and using computer-controlled scanning motor to push the reflector X and Y axis rotation, the laser beam is focused and falls on the marked workpiece to form the laser mark trace.
