Ultraviolet laser marking machine, the reaction mechanism during processing is realized by photochemical ablation, that is, relying on laser energy to break the bonds between atoms or molecules, so that small molecules are vaporized and evaporated. The focusing spot is extremely small, and the processing heat affected zone is very small, so uv laser marker can be used for ultra-fine marking and special material marking.
Today, with the rapid development of laser equipment and the increase in the power of UV laser, UV laser marking machines have been used in the ultra-fine processing market. Such as:
Surface marking of iPhone, cosmetics, pharmaceuticals, food and other packaging bottles for polymer materials;
Flexible PCB board marking and cutting;
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.
Many common signs in our daily life, such as metal or non-metal marks, text and patterns, BMW logo, mobile phone buttons, etc., these patterns are marked by UV laser marking machine. The principle is that the laser light energy of the UV laser marking machine evaporates the surface layer of the target material to expose the deep layer of the material, thereby “engraving” the desired pattern and text. Simply put, it uses a laser beam to print long-lasting marks on the surface of various substances.
Most materials can absorb UV laser, such as consumer electronics, mobile phone parts, LCD screen engraving QR code and trademarks, ceramics, sapphire sheet, capacitive touch screen ITO etching, etc. All these can be marked by UV laser marker. Glass can only be marked with a UV laser marking machine.
In general, the application range of UV laser marking machine is relatively wide.
