The working principle and application range of UV laser marking machine

Ultraviolet laser marking machine belongs to a product in the series of laser marking machines. Because the traditional laser marking machine adopts laser thermal processing technology, the optimization space obtained in terms of accuracy has limited development. However, ultraviolet laser marking machine Machine use is a kind of cold working, so the accuracy and thermal influence are reduced.

Working principle of UV laser marking machine:

The reaction mechanism of UV laser processing is realized by photochemical ablation, that is, relying on laser energy to break the bonds between atoms or molecules, making them gasify and evaporate into small molecules. The focusing spot is small, and the processing heat affected zone is very small,

Application range:

Today, with the development of laser equipment and the optimization of the power of UV laser marking machines, UV laser marking machines have been applied to the surface marking of packaging bottles of cosmetics, medicines, food and other polymer materials; flexible PCB board marking, Dicing; silicon wafer micro-hole, blind-hole processing; LCD liquid crystal glass, glassware surface, metal surface coating, plastic buttons, electronic components, communication equipment, building materials and other fields.

Many common signs in our daily life, such as metal or non-metal marks, text and patterns, signs, mobile phone buttons, etc., these patterns are marked by UV laser marking machine. The principle is that the laser light energy of the ultraviolet 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.

Most materials can absorb UV laser, such as electronics, mobile phone parts, LCD screen engraving two-dimensional code and trademarks, ceramics, capacitive touch screen ITO etching, etc. can be used for UV laser marking machine.

Glass can only be marked with a UV laser marking machine. In general, the application range of UV laser marking machine is relatively wide.
