The laser marking machine uses a laser beam to make permanent marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, thereby engraving exquisite patterns, trademarks and text. The laser marking machines currently used on the market are mainly divided into the following types:
1. Fiber laser marking machine
The fiber laser marking machine uses a fiber laser. The fiber laser has the characteristics of small size (no water cooling device, air cooling), good beam quality (fundamental mode), and maintenance-free.
Mainly used in: marking the required text, pattern, bar code and other graphics on plastic, electronics, metal, ceramics, tobacco and other materials.
2. Ultraviolet laser marking machine
The UV laser marking machine is developed with a 355nm UV laser. The 355 ultraviolet light has a very small focusing spot, which can reduce the mechanical deformation of the material to a great extent and has little processing heat influence. It is mainly used in products that enterprises have higher requirements on text, patterns and so on.
3. Semiconductor laser marking machine
The main application industry is the same as that of fiber laser marking machine, but as the market competition becomes more and more fierce, the progress of fiber technology is getting faster and faster. Now the semiconductor laser marking machine on the market has been gradually replaced by the fiber laser marking machine.
4. CO2 laser marking machine
CO2 laser marking machine is mainly used in some occasions that require finer and higher precision, such as non-metal industries such as food, medicine, leather, tobacco, wood products, and electronics. The marking effect is more delicate and beautiful than the silk screen and inkjet effect.
5. End pump laser marking machine
The end face laser marking machine uses a solid-state laser pumped by a semiconductor laser as the pump source, and the laser crystal is injected from the end face after fiber coupling. The pump beam enters the gain medium and overlaps the cavity mode space 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 fiber laser marking machine, and its performance is similar to that of the fiber laser marking machine, but its peak power is higher.
6. Green laser marking machine
Mainly used in the surface and internal marking of glass and crystal products, ceramics, metals, electronics, plastics and other products. It belongs to the category of cold light, and it is also very suitable for some products that have a larger response to heat and require higher precision.
7. Flying laser marking machine
It is a dynamic marking function developed on the basis of the above several laser marking machines. It is mainly used in assembly line operations. It can mark products without restrictions for 360 days. It can also automatically generate serial numbers and batch numbers, which greatly improves the company. Production efficiency.
