Due to its special beam characteristics, laser engraving machines play an extremely important role in the upgrading of traditional printing and inkjet fields, and continue to penetrate into various industries of industrial production. With its unique advantages, it has become an important processing technology in the manufacturing industry and is known as a new processing technology in the 21st century. Among them, laser engraving machine is an extremely important part of laser technology. As a series of laser engraving machines, UV laser engraving machine is a newly developed and mature laser processing technology. Since the traditional laser laser engraving machine adopts laser thermal processing technology, in the field of modern precision processing, the development of precision is limited. In this context, the UV laser engraving machine has become the darling of the new era. It uses a cold working process, a process known as the "photolithography" effect. "Cold processing" has high load energy (ultraviolet) photons, which can destroy the chemical bonds in the material or the surrounding medium until the material is destroyed by a non-thermal process, and the inner layer and nearby areas do not generate heating or thermal deformation. Finally, the processed material has smooth edges and extremely low carbonization, so fineness and thermal influence are minimized, which are the main characteristics of laser technology. Today, with the rapid development of laser equipment and the increase in the power of UV laser engraving machines, UV laser engraving machines have been used in the high-end market for ultra-fine processing, to engrave the surface of packaging bottles of iPhone, cosmetics, medicines, food and other polymer materials. Marking and scribing of flexible printed boards; micro-hole and blind hole processing of silicon wafers: liquid crystal glass, glassware surface, metal surface coating, plastic keys, electronic components, gifts, communication equipment, building materials and many other fields . There are many common signs in our daily life, such as metal or non-metallic marks, text and patterns, product logos, mobile phone buttons, etc. , are all marked with a UV laser laser engraving machine. The principle is that the laser light energy of the ultraviolet laser laser engraving machine evaporates the surface layer of the target material, exposing the deep layer of the material, thereby "engraving" the required pattern text. In simple terms, laser beams are used to print permanent marks on the surface of various materials. Compared with the traditional printing inkjet technology, the engraving effect of the UV laser engraving machine is finer, more environmentally friendly, smarter, and more in line with the automation requirements of modern industry.
