Ultraviolet laser marking machine that is getting more and more attention

Ultraviolet laser marking machine can also be called ultraviolet laser marking machine, UV ultraviolet laser marking machine, ultraviolet laser laser engraving machine, ultraviolet laser marking machine principle: same as ordinary fiber laser marking machine, it also uses laser beam The surface of various substances is coded and marked for long-term marking. The reaction mechanism during ultraviolet laser processing is realized by photochemical ablation, that is, relying on laser energy to break the bond between atoms or molecules, making it into small molecules to vaporize and evaporate Lose. The focused spot is extremely small, and the processing heat-affected zone is minimal, so it can be used for ultra-fine marking and special material marking.

     With the rapid development of laser equipment and the increase in the power of UV laser marking machines, UV laser marking machines have been used in the high-end market for ultra-fine processing, marking the surface of packaging bottles for iPhone, cosmetics, medicines, food and other polymer materials. ; Flexible PCB board marking and scribing; silicon wafer micro-hole and blind hole processing; LCD liquid crystal glass, glassware surface, metal surface coating, plastic buttons, electronic components, gifts, communication equipment, building materials and other fields .

The process of ultraviolet laser processing is called the "photoetching" effect. "Cold processing" has high-energy (ultraviolet) photons that can break the chemical bonds in the data or the surrounding medium to cause non-thermal process damage to the data. This kind of cold processing has a special meaning in laser symbol processing, because it is not thermal ablation, but cold peeling that breaks chemical bonds without the side effect of "thermal damage", so it has no effect on the inner layer and adjacent areas of the processed surface. Heat or thermal deformation occurs. The processed materials have lubricated edges and extremely low carbonization.

Under the environment of industrialized mass automated production line, the UV laser marking machine has become an industrial processing manufacturer due to its advantages of light quality, high peak value, narrow pulse width, and small heat impact during processing. Under the condition of higher electro-optical conversion efficiency, it has become an industrial processing manufacturer. The darling, can meet the needs of industrialized mass production marking.

  Compared with the heating type processing of co2 and fiber laser marking machine, there will be a big limitation in terms of fineness. Therefore, everyone is constantly developing and researching, and the UV laser marking machine is developed, which can be easily solved. difficulty. The UV laser marking machine uses a cold processing technology, and cold processing has many advantages. It can cut off the chemical bonds in the material or the surrounding medium, so that the material is not easily damaged by overheating, and it is not easily deformed by overheating. Affect the aesthetics of the product. Today's UV laser marking machines are often used in high-end markets that apply fine processing, such as iPhone, cosmetics, pharmaceuticals, food and other polymer materials for packaging bottles, as well as flexible PCB board marking, LCD liquid crystal glass, glassware Appearance, plastic buttons, electronic originals, gifts, communication equipment, building materials and other fields.

      On each product, everyone sees more or less text, patterns, etc. These patterns or texts are actually marked by UV lasers. Compared with traditional marking machines, UV lasers The marking and marking effect of the marking machine is more refined, more environmentally friendly, more intelligent, and more in line with the automation requirements of modern industry.
