1. At present, the laser marking machines in the market mainly include CO2 laser marking machine, semiconductor laser marking machine, optical fiber laser marking machine and ultraviolet laser marking machine, etc. at present, the laser marking machine is mainly used in some occasions with more precise requirements and higher precision.

2. UV laser marking machine is a series of laser marking machines, so its principle is similar to that of the laser marking machine. It is the permanent marking of a laser beam on different material surfaces. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "carve" the traces through the chemical and physical changes of the surface material caused by the light energy, or to burn part of the material through the light energy, showing the required etched patterns and characters.

3. It is developed by using a 355nm UV laser. Compared with an infrared laser, this machine adopts the third-order intracavity frequency doubling technology. The focus spot of 355 UV light is very small, which can greatly reduce the mechanical deformation of materials and has little heat effect on processing. Because it is mainly used for ultra-fine large surface and carving, it is especially suitable for marking, microporous and glass materials of food and medicine packaging materials It integrates advanced international technology into the application fields such as complex graphic cutting of silicon wafer, The high-energy ultraviolet photons directly destroy the molecular bonds on the surface of many non-metallic materials and make the molecules separate from the objects. This way will not produce high heat. The UV laser focus spot is very small, and the processing has almost no heat effect, so it is called cold processing, so it is suitable for ultra-fine marking and carving of special materials.

4In the 1990s, laser technology has successfully developed UV laser marking equipment with decades of unremitting efforts in laser technology, optics, crystals, and other energy sources, and has attracted extensive attention in the world, and has taken the lead in the application of photovoltaic, glass, film and other industries. Moreover, the successful development of this technology has solved the oxidation change of metal surface marking and the problem of atomic active matter for a long time. The 355nm cold laser technology used for the ultraviolet laser will also have a great impact on the external optical path and spectral energy assembly.

5. In the process of assembly, some high-precision ellipse marking needs rotating matching facilities, which can realize the rotating arc marking.

6. After the successful study of UV laser marking, it has prayed for supporting construction in the fields of energy, materials, etc. it also plays a great indirect role in the country's GDP, and solves many major scientific problems, which plays a decisive role in the future development. Laser technology, as an important scientific research technology in modern molecular structure, is a technical means to study the strength of various molecular structures and has been widely used in marking applications in the glass, crystal, photovoltaic, and other high-tech industries. Laser marking technology, especially in the development of these decades, has been gradually greater development, and in the continuous exploration of successful international applications.
