Laser marking machine can be said to be a necessity in many fields, but many people do not know how laser marking machine is engraved. Laser marking machine engraving principle is the use of laser energy focus, immediately focused on the injection material, and then through high-speed operation, so that the surface of the material to produce a special mark such as bump or wave-shaped road. This method is like the light from a typewriter hitting a lettering mold, just like a laser hitting a stone, but the marking machine should not use any specialized tools. The method of engraving must be determined according to the differences of the product. Laser engraving machine marks are divided into two forms: photolithography and film. Both require a laser. Laser engraving machine has a variety of different light paths, you can use the laser dry engraving; laser does not cause residual material or mechanical instability due to insufficient temperature and pressure, resulting in serious damage to the surface of the material irradiated by the laser beam or can not be marked; laser engraving does not require marking and mechanical marking; laser marking can be used to generate three-dimensional patterns and text. Laser engraving machine can engrave a variety of non-metallic materials, including wine bottle mark, wine bottle packaging mark, handicraft mark, porcelain mark, non-woven fabric cutting, shell nameplate mark, wood products mark, leather mark, stainless steel mark, etc. Many common marks in our life, such as metal or non-metal marks, text and its patterns, logos, cell phone buttons, etc., are also marked by UV laser marking machine. The principle is that the laser of UV laser marking machine can volatilize the surface of the target material, expose the deep layer of the material, and then “engrave” the desired pattern text. Simply put, it is a mark printed with a laser on the surface of various materials. The following is an introduction to the principle of UV laser marking machine. UV laser marking machine is a common type of laser marking machine. Side pump for UV laser marking machine, unlike semiconductor end pump laser 1. Select the appropriate laser power according to different product materials, generally between 800~60,000 W. The laser marking machine is first adjusted when in use. The marking effect is determined and screened and differentiated according to the different types of cutting situations. Compared with other industrial machines, laser marking machine has high cutting accuracy, good stability, not easy to damage, pollution and other issues, due to the different processing materials, different laser power, the effect is also different, but some are also very good. Such as stainless steel, aluminum alloy, porcelain and other materials. Laser marking equipment is generally made of non-metallic materials. According to different fields and product use regulations to choose the appropriate laser and parameters. Only in this way, the marking effect of the equipment can be very perfect. If there are abnormalities can also be repaired in time. 2. Preheat the electrode and keep the electric level temperature 30℃ or less. The preheating time of the equipment is usually 3-5 minutes. In the preheating process, once the processing surface is soot and other components, will make the engraving very dry, resulting in laser stagnation on the surface of the engraved material, resulting in laser damage can not work; in this case, some solvent must be used to make the electrical stage and laser contact enough to evaporate the solvent to reduce the impact on the workpiece. A certain isolation layer is needed between the electric stage to ensure normal operation when the laser is exported; generally choose the electric stage PET or copper tube material as the electric stage, if it is a metal material, you can choose other materials appropriately; the electric stage will contact the struck object, pay attention to protection; after preheating, use a multimeter to measure about 120 degrees between the electrode and the struck object, if it is a heat-sensitive material, it should be heated; if it is a heat-sensitive material or porcelain material, it is better to choose no radiation; in this way, there will not be any heat loss and other problems during the engraving process. 3. Cut the surface of the workpiece with a high-speed laser and engrave characters quickly under a high-intensity laser. Due to the development of laser engraving technology, the laser engraving machine can now be applied to any material. There is no need for heat treatment of the workpiece, and the method of direct indirect marking by laser is generally used. For some products with rough surface or high requirements, surface laser engraving can be solved in seconds without causing any damage to the goods during the operation. In addition, laser engraving allows for instant display of character specifications, location and size. Laser engraved parts processed by this method can intelligently solve production problems, which not only saves labor and material resources, but also reduces product costs and improves product quality and output. Its advantages are. 1. low cost: cheap price. 2. Short time (10-40 seconds). Workpiece specifications are particularly small; 5-10 mins can be completed. Suitable for: stainless steel, copper parts, aluminum alloy ABS, PPS and plastic and other plates, the general accuracy of the marking machine is 0.1 mm among them, will not cause harm; for some areas with high precision requirements, such as hardware or plastic mold. 3. Short manufacturing cycle: the surface of the workpiece after certain treatment, can indicate a variety of graphics and text.
