Working principle of UV laser marking machine:

RFH UV laser marking machine is developed by using a 355nm UV laser. This machine uses a third-order intracavity frequency doubling technology. Compared with infrared lasers, the 355 UV laser has a very small focused spot, and the marking effect is directly interrupted by a short-wavelength laser. The molecular chain of the substance greatly reduces the mechanical deformation and thermal deformation of the material (cold light), because it is mainly used for ultra-fine marking and engraving, and is especially suitable for marking, micro-holes, and glass materials for food and medical packaging materials. Application industries such as high-speed division of silicon wafers and complex pattern cutting of silicon wafers. Our company uses international advanced technology and cooperates with German and American laser companies to develop an advanced laser marking machine; UV laser is a UV laser beam that is pumped by a high-power multi-mode laser diode to generate a laser and double frequency, and then passes The computer controls the deflection of the high-speed scanning galvanometer to change the optical path of the laser beam to realize automatic marking.

Model features of UV laser marking machine:

High beam quality, very small spot, can realize ultra-fine marking;

Nearly perfect marking quality: 355nm output wavelength reduces the thermal impact on the processed parts;

galvanometer-type high-precision marking head, with fine marking effect and repeatable processing;

high-precision and meticulous spot to ensure perfect marking results; marking The process is non-contact, and the marking effect is permanent;

Ultraviolet laser marking machine has a wide range of applications;

The heat-affected area is very small, there will be no thermal effect, and the material will not be deformed or scorched;

UV laser marking machine Fast marking speed and high efficiency;

The whole machine has stable performance, small size and low power consumption. It is more suitable for processing materials with large thermal radiation reaction;

it can be matched with the production line, automatic loading and unloading, automatic feeding and discharging; suitable for marking on most metal and non-metal materials;

Main advantages of UV laser marking machine:

Due to the very small focus spot and the small processing heat affected zone, the UV laser can be used for ultra-fine marking and special material marking. It is a must-choice product for customers who have higher requirements for marking effects. Ultraviolet laser is suitable for processing almost all materials except copper materials. Flexible and convenient operating system: the operation process is humane, and the equipment is stable; the dedicated control software is compatible with AutoCAD, CorelDRAW, Photoshop and other software output; it can realize text symbols, graphic images, bar codes, two-dimensional codes, serial numbers Automatic layout and modification; supports PLT, PCX, DXF, BMP, JPG and other file formats, and can directly use TTF font library; CCD automatic recognition and tracking positioning; UV laser marking machine

Industry application of UV laser marking machine:

It is mainly used in the high-end market of ultra-fine processing, marking the surface of packaging bottles of medicines, cosmetics, videos and other polymer materials, with very fine effect, strong marking and cleaning, better than ink printing and no pollution; flexible PCB marking, Scribing; Silicon wafer micro-hole and blind hole processing; LCD LCD glass two-dimensional code marking, surface drilling of glassware, metal surface coating marking, plastic buttons, electronic components, gifts, communication equipment, building materials, etc. .
