Fiber lasers are an important component of fiber laser cutting machines. Fiber lasers refer to lasers that use rare-earth-doped glass fibers as gain media. Under the action of pump light, high power density is easily formed in the optical fiber, which causes the laser energy level of the laser working material pair to "invert the number of particles." Properly adding a positive feedback loop can form a laser oscillation output.
At present, laser marking machines are mainly used for electronic components, integrated circuits, electrical appliances, mobile phone communications, hardware products, tool accessories, precision equipment, glasses and watches, jewelry, auto parts, plastic buttons, building materials, PVC pipes and other requirements. Finer, higher precision industries.
Metal laser marking machine Laser marking machine can engrave a variety of non-metallic materials. CO2 laser marking machine is used for metal laser marking machines in clothing accessories, pharmaceutical packaging, alcohol packaging, building ceramics, beverage packaging, fabric cutting, rubber products, casing nameplates, craft gifts, electronic components, leather and other industries. . Metal laser marking machine can not only improve the marking quality and processing effect of products, but also provide convenient controllable flow of products for the majority of enterprises while protecting the intellectual property of the products.
Principle of fiber laser marking machine
Fiber laser marking machine is using laser beam to mark permanent marks on the surface of various materials. The effect of CO2 laser marking machine marking is to expose deep matter through evaporation of surface substances, or to etch out traces through chemical and physical changes of surface substances caused by light energy. Fiber laser marking machine is the most advanced laser marking equipment in the world. It has the characteristics of good beam quality, small size, fast speed, long working life, flexible and convenient installation, and maintenance-free.
The laser marking machine has shallow typing reasons:
• The lenses are dirty and stained
This problem can be solved by simply using some cotton swabs, dipping some alcohol on it, and scrubbing the lenses, beam expanders, and focusing lenses of the marking machine to remove the stains on it. Up;
• The light path has deviated
CO2 laser marking machine is suitable for which industries have this situation, it is necessary to readjust the optical path to restore it to the best state;
• Marking speed is too fast and filling method is unreasonable
In this case, the marking speed can be reduced, and the original filling method can be adjusted. In addition, it is necessary to determine whether the workpiece is on the top and readjust the focus;
• Laser marking machine current problem
If it is because the power supply current of the device is too small, it will also affect the depth of the marked characters or patterns.
