How many types of UV Laser Diode marking machine
Aug 18 , 2021Laser marking machines use laser beams to mark permanent surfaces on a variety of different materials. The effect of the marking is to expose the deep material through the evaporation of the surface material, thereby engraving beautiful patterns, trademarks and words. The marking machines currently used in the market are mainly divided into the following main types:
Fiber laser marking machine uses fiber laser. Fiber laser has the characteristics of small size (no waterless device, air cooling), good beam quality (basic mode) and maintenance-free.
UV marking machine is developed using 355nm UV laser. The focus point of 355 UV is very small, which can greatly reduce the mechanical deformation of the material and has little effect on the processing heat. Mainly used for companies that have higher requirements for text, graphics and other products.
The main application industry is the same as that of the optical fiber marking machine, but with the increasingly fierce market competition, the advancement of optical fiber technology is getting faster and faster. Semiconductor marking machines on the market have been gradually replaced by optical fiber marking machines.
CO2 marking machine is mainly used in the occasions that require more precision and precision, such as non-metal industries such as food, medicine, leather, tobacco, wood products, and electronics. The effect of marking is more refined and beautiful than that of screen printing and inkjet printing.
The end face marking machine uses a solid-state laser pumped by a semiconductor laser as the pump light source, and is coupled to the laser crystal from the end face through fiber coupling. The pump beam enters the gain medium to overlap the cavity mode to the greatest extent, so that high-power and high-beam quality laser output can be obtained. The main application industry is also the same as the optical fiber marking machine. Its performance is similar to that of the optical fiber marking machine, but its peak power is higher.

Mainly used for the surface and internal marking of glass and crystal products, ceramics, metals, electronics, plastics and other products. It belongs to the cold light category and is also suitable for products with higher thermal response and higher precision.
It is a dynamic marking function developed on the basis of the above-mentioned marking machines. It is mainly used in assembly lines. It can be used for 360 days without limitation in marking on the product. It can also automatically generate serial numbers and batch numbers, which greatly improves the enterprise. Productivity.
