The laser marking machine can be divided into ultraviolet laser marking machine, optical fiber laser marking machine, CO2 (carbon dioxide) laser marking machine and other types according to the different ways of generating laser. The application range of different types of laser marking machines is also different. Why do different materials use different laser marking machines.
Ultraviolet laser marking machine relies on laser energy to break the combination between atoms or molecules, so that they become small molecules, vaporize and evaporate. Because of its very small focus spot and very small processing impact area, it can carry out ultra fine marking, and special material marking laser marking machine.
Application field: mainly used in ultra fine processing, such as marking on the surface of packaging bottles of iPhone, cosmetics, drugs, food and other high polymer materials, marking on flexible PCB boards, scribing, silicon wafer microporous, blind hole processing, LCD liquid crystal glass, glassware surface, metal surface coating, plastic keys, electronic components, gifts, communication equipment, building materials, etc.
The optical fiber laser marking machine uses the optical fiber laser to output the laser, and then through the high-speed scanning galvanometer system to achieve the marking function. The optical fiber marking machine has a high photoelectric conversion rate, and can engrave metal materials, optical fiber laser marking machine and some non-metallic materials. It is mainly used in areas with high depth, smoothness and fineness. Bitmap marking can mark beautiful patterns on metal, plastic and other surfaces.
Application field: It is used in hardware products, tool accessories, precision instruments, glasses, clocks, jewelry, auto accessories, plastic keys, building materials, food, medicine, electronic components, integrated circuits (IC), electrical appliances, mobile communication, PVC pipes, sanitary ware and other industries.
Use and replacement of krypton lamp.
1. Turn off the water cooler and laser power supply, open the upper three chamber covers, take out the lamp or crystal to be replaced, put it in after replacement, and install the chamber cover.
2. Turn on the water cooler and laser power supply, adjust the laser power supply current to about (15~20) A. Put a small piece of wood or black paper between the front diaphragm and the beam expander. You should see the light spot formed by laser ablation. If not, slightly adjust the three knobs of the front diaphragm bracket until a light spot appears.
3. After the laser is debugged, the three knobs of the front diaphragm bracket should be adjusted repeatedly to make the facula strongest. If the laser is too strong or the brightness is too high, the power supply current can be reduced and the ultraviolet laser marking machine can be used.
