How to distinguish the different types of laser marking machines?
Visual laser marking machine
There are many types of laser printers in the market. How can we distinguish the different types of laser printers? With regard to the differences between different types of laser marking machines, Guanchengda Machinery will elaborate from the following three dimensions, hoping to help you understand, learn and use different types of laser marking machines.
1. The optical wavelength of the laser marking machine can be distinguished as follows:
A. UV dao laser marking machine: 355nm
B. Deep ultraviolet laser marking machine: 266nm
C. Optical fiber laser marking machine: 1064nm
D. Co2 laser marking machine: 1064nm
E. Green laser marking machine: 532nm
F. Semiconductor laser marking machine: 1064nm
2. The marking category and specific price of laser marking machine can be distinguished as follows:
A. Ultraviolet laser marking machine: It is mainly used in some high-end sales markets where ultra-high precision marking is required. It can be used in all materials. The actual effect of laser marking is more precise and more refined, but the price is relatively high.
B. Green light laser marking machine: similar to UV laser marking machine, it is mainly used in some high-end and meticulous marking IC products. The products are mainly customized, so the price is relatively high.
C. The semiconductor end-pump laser marking machine is mainly used in some metal materials, plastics and other products. It is often used in high-end products. Its overall characteristics are stable and power saving, so the price is high.
D. Lamp pump YAG and semiconductor side pump laser marking machine are all used in low-specification products such as metal materials and plastics. The whole equipment features stable characteristics, and the actual effect of laser marking is also exquisite, and the price relativity is moderate.
E. Optical fiber line laser marking machine: It is mainly used on some metal materials, and is widely used in electronic devices. It has the characteristics of laser marking meticulous, power-saving, maintenance-free, and long-term operation. It is often used on some high-end products, so the price is high.
F. Carbon dioxide laser marking machine: It is mainly used on some non-metallic materials: wood, acrylic board, paper board, leather products, plastic and other products that are easy to mark the bottom, so its price is low, and it is the most cost-effective of many laser marking machines.
3. The basic principle of laser marking machine can be distinguished as follows:
1. CO2 laser marking machine: a kind of particle beam that uses carbon dioxide vapor as the material, widens the working voltage on the electric level and puts it into the electric tube to release the molecular structure of the vapor from the laser, and carries out production and processing on the product itself
2. Fiber line laser coding machine: the key is to immediately output the laser from the fiber line, and carry out production and processing at the raw material supplier required for production and processing
3. Lamp hydraulic plunger pump YAG laser printer: select oxygen lamp as energy source, YAG as material, and send out special light wavelength to promote the release of chemical substances from the laser during work, and finally generate particle beam that can be used for production and processing on materials.
4. Semiconductor side pump YAG laser marking machine: The semiconductor laser diode hydraulic plunger pump with 808 nm wavelength is applied to closely combine with Nd: YAG as the material, so that the material causes a lot of overturned particles to produce giant pulse light output with 1064 nm wavelength under the effect of power switch, and the photoelectric conversion efficiency is high.
5. Electric conductor end-pumped YAG laser marking machine: immediately pump the semiconductor hydraulic plunger pump light (808nm) from the inner hole of the laser crystal, and the laser conversion efficiency is further improved by the output of the optical lens group.
