Adjusting the power of frequency conversion in laser carving of clothing

The main shaft of finely processed clothing laser carving is characterized by low noise, high speed and high height, which is suitable for processing specially fine workpieces, such as seals, nameplates, chest cards and gifts. This kind of motor is usually a high-speed variable-frequency motor with small power, generally under 250W. The disadvantage is that the ability to cut thick material is poor, and it is not suitable to cut thick material. Laser processing technology is a technology that uses the characteristics of the interaction between laser beam and material to cut, weld, surface treatment, punch, micro machining materials (including metal and non-metal), as well as to identify objects as light sources. The largest traditional application field is laser processing technology. Laser technology is a comprehensive technology involving many disciplines such as optics, mechanics, electricity, materials and detection. Traditionally, its research scope can be generally divided into:
1. Laser processing system. Including laser, light guide system, machining machine, control system and detection system.
2. Laser processing technology. Including cutting, welding, surface treatment, drilling, marking, marking, fine adjustment and other processing technology. Laser welding: automobile body thick sheet, automobile parts, lithium battery, pacemaker, sealed relay and other sealing devices as well as various devices that are not allowed to weld pollution and deformation. At present, YAG laser, CO2 laser and semiconductor pump laser are used.
Clothing laser engraving photochemistry: the traditional chemical process, which involves mixing reactants together and then heating (or pressurizing). The disadvantage of heating lies in the irregular movement of molecules due to the increase of energy, which destroys the original chemical bonds and combines them to form new bonds. These irregular movements destroy or generate bonds, which will hinder the expected chemical reactions. But if we use laser to direct chemical reaction, we can not only overcome the irregular movement, but also get more benefits. This is because the laser carries a highly concentrated and uniform energy, which can be accurately hit on the molecular bond. For example, using ultraviolet laser of different wavelengths to hit molecules such as hydrogen sulfide, and changing the phase difference between the two laser beams, the molecular fracture process is controlled. We can also use the method of changing the pulse shape of the laser to hit the energy on the molecule accurately and effectively, triggering some expected reaction.
