High-power and UV Lasers help power adapter laser engraving applications

In recent years, the popularity of mobile phones, computers and other markets has set off a large number of applications of peripheral accessories. Power adapters are also getting a piece of the craze. With the demand of the market, the emergence of laser marking machine quickly replaced the silk screen process. Laser marking is a clean, pollution-free and highly environmentally friendly processing technology. It has non-contact marking, high marking accuracy and high definition. , good permanence, strong wear resistance and so on.

5w UV laser marking machine has good beam quality, extremely small focusing spot, can achieve ultra-fine marking, and the marking is exquisite and permanent, with high anti-counterfeiting. Ultraviolet lasers are cold light sources. The heat-affected zone is extremely small during laser marking or laser cutting, and no thermal effect is produced. Most materials can absorb ultraviolet lasers, so they are widely used.

The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of shells, transformers, inductors, capacitors, control ICs, PCB boards and other components. There is a nameplate on the power adapter, which indicates the power, input and output voltage and current, etc. These data are relatively important, so these marks must not have any damage.

The traditional way of marking is to use silk screen printing to print on the surface. The silk screen printing ink has a strong contrast, the dots are not delicate enough, it is difficult to follow the color, the printing effect is not ideal, the marked information is easy to fade and fall off, and the ink components used in silk screen printing are all chemical elements. , Now all businesses specify the need to use new low-carbon and environmentally friendly processes.

The reaction mechanism of the 5w UV laser marking machine of RFH laser 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 extremely small, and the processing heat affected zone is very small, which can carry out ultra-fine marking and special material marking.
