Introduction and working principle of 5W UV laser marking machine

 

The laser marking machine essentially uses a laser beam to make permanent marks on the surface of various materials. However, the marking effect of the laser marking machine is to expose the deep material through the evaporation of the surface material, thereby engraving exquisite patterns, trademarks and characters. The laser marking machine is mainly divided into CO2 laser marking machine and semiconductor laser marking machine. , Fiber laser marking machine and YAG laser marking machine. At present, laser marking machine is mainly used in some occasions that require finer and higher precision. There are everything in application, which can be found in all aspects of our lives. It is used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, precision equipment, glasses and watches, jewelry, automobiles Accessories, plastic buttons, building materials, PVC pipes, etc.

 

UV laser marking machine

 

Here, I want to share with you the specific working principle of the laser marking machine. It uses a laser beam to perform operations. We have also mentioned this before. It acts on the surface of different materials and uses a laser beam to make permanent markings. Mark. But we now recognize two principles: the first is thermal processing. This thermal processing itself has a laser beam with a higher energy density. It is a concentrated energy flow that irradiates the surface of the processed material and absorbs it on the surface of the material. The laser energy produces a thermal excitation process in the irradiated area, which causes the temperature of the material surface or coating to rise, causing phenomena such as metamorphosis, melting, ablation, and evaporation. The second is thermal processing. "Heat processing" has a laser beam with a higher energy density (it is a concentrated energy flow), which is irradiated on the surface of the material to be processed. The surface of the material absorbs the laser energy and produces a thermal excitation process in the irradiated area. , So that the temperature of the material surface (or coating) rises, causing phenomena such as metamorphosis, melting, ablation, and evaporation.

 

Cold processing has special significance in UV laser marking processing

 

In fact, the most important thing I want to say is cold processing. Cold processing itself has high-load energy (ultraviolet) photons, which can break the chemical bonds in the material (especially organic materials) or the surrounding medium, and cause the material to undergo non-thermal process damage. . This kind of cold processing is of special significance in laser marking processing, because it is not thermal ablation, but cold peeling that does not produce the side effects of "thermal damage" and breaks chemical bonds, so it does not affect the inner layer and nearby areas of the processed surface. Produce heating or thermal deformation. For example, in the electronics industry, excimer lasers are used to deposit thin films of chemical substances on base materials and to cut narrow grooves on semiconductor substrates. Therefore, we have to understand the working principles of the laser marking machine, and then we can prescribe the right medicine before we can implement the work according to our needs.
