Principle and maintenance of UV laser marking

The general effect of laser marking machine is that it can mark long-term marks on the surface of different materials. It can cause chemical and physical reactions on the surface material to change into "engraving" (light/CO2), but people who have not touched it will think that light energy causes light contact processing on the surface of the material to show the pattern by burning the surface. Word.

The ultraviolet laser marking machine to be mentioned here can be known from its laser head that the ultraviolet laser is a high-load cold processing. The laser marking machine can break the chemical bonds in the material or the surrounding medium, so that the material can be damaged again. Destruction by thermal process. This cold working has a similar meaning in laser marking, because it is not a thermal laser, but a cold extrusion that stops the chemical bonds without the side effect of "heat damage", thus affecting the inner layer and adjacent areas of the machined surface. There is no cooling or thermal deformation, etc., we can call this process the "photolithography" effect.

In the field of modern precision machining, because the traditional laser marking machine adopts laser thermal processing technology, the development of fineness is limited. Under this background, the ultraviolet laser marking machine has become the new era of ultraviolet laser marking machine. darling.

In the field of UV laser marking machine, it is mainly used for marking: flexible PCB board marking, FPC board cutting, silicon wafer, LCD liquid crystal glass, metal surface coating marking, plastic buttons, electronic components, gifts, Communication equipment, building materials, Apple data cable, high-demand light-transmitting buttons, plastic parts that have passed UV oil and other materials that are very special to light. The component hardware of the UV laser marking machine in daily work is constantly working, and long-term work will make it wear out.

1. When the laser beam of the UV laser marking machine is working, it should be noted that it cannot contact the end-pumped laser marking machine or collide with the beam of the workbench, etc. These are the matters that customers should pay attention to when operating the laser marking machine.

2. Although the effect of processed products will not subside due to environmental factors, the processing environment still needs to be paid attention to. The environment, temperature and humidity of the processing site must meet the standards to ensure that the site is clean and tidy, and the work surface should also be kept clean to ensure that the processing materials are not polluted.

3. Antes del procesamiento, se debe inspeccionar toda la máquina de marcado láser UV y se debe mantener el sistema de enfriamiento, el sistema de trayectoria óptica y el iterbio de campo de la máquina. Asegure el trabajo normal de cada sistema y garantice el efecto de procesamiento.
