co2 laser marking machine laser marking machine types introduction

Processing principle of long-pulse laser marking machine:

Under the irradiation of strong light of long-pulse laser marking machine, the material passes through incident photons. - Energy is absorbed by excited electron-phonon conversion, and the material achieves the processing effect of the material through the solid-liquid-gaseous three-phase hot-melt process. Eventually, serious thermal effects and thermal damage will be caused in the edge state of the active area. With the reduction of the pulse width of the pulsed laser, the area and degree of thermal effects and thermal damage will decrease. On the other hand, due to the longer duration of the laser pulse, its corresponding Therefore, it is impossible to process relatively transparent dielectric materials, and the processing range is strictly limited by the light absorption characteristics of the material.

Processing principle of short pulse laser marking machine: .

The pulse width of the femtosecond laser marking machine is much smaller than the thermal diffusion time and the electron-phonon coupling in the material. During the entire continuous irradiation time, only the excitation and energy storage processes of electrons absorbing incident photons need to be considered, while the temperature of electrons can be completely ignored in the process of cooling and thermal diffusion through radiation phonons. The process of stimulated absorption and storage of energy fundamentally avoids the transfer, transformation of energy and the influence of the existence and diffusion of thermal energy, so when the laser pulse is incident, the energy generated by absorbing photons will be within a few nanometers. The thickness of the absorption layer accumulates rapidly, and the temperature value of electrons generated in an instant will be much higher than the melting temperature of the material, or even the vaporization temperature, so that the material is directly converted from a solid state to a gaseous state, and a high-density, super-heated, high-pressure gas is formed on the laser-irradiated surface of the material. In the plasma state, non-thermomelting laser processing is realized.

Femtosecond laser marking machine is widely used in assembly line industrial production. It is suitable for batch automatic marking machine. The marking speed is fast and the effect is obvious. It is the batch number. One of the important tools for marking the production date with the UV laser marking machine, the femtosecond laser marking machine has no consumables, non-contact marking, and meets the needs of environmental protection. Products that have requirements for environmental protection are a good choice for the femtosecond laser marking machine.

First, fiber laser marking machine.

Fiber laser marking machine is called metal laser marking machine. Almost all metal products can be permanently marked on it, and it can also be used on some plastic products. Marking can also produce certain effects, such as plastic ABS and PC material marking.

Second, co2 laser marking machine.

The co2 laser marking machine is called non-metallic laser marking machine, which is mainly aimed at marking wooden materials. Marking on wood products can also be used for part of work engraving, also known as carbon dioxide laser engraving machine, some glass products and clothing marking and printing, also use co2 marking machine.

Three.

Also known as plastic laser marking machine, IC automatic laser marking machine is currently widely used in the electronics industry to drive the market share, and also belongs to a This type of fine laser marking machine, the marking accuracy is higher than the above two, the Z line width will be smaller, in addition to marking on plastic, it can also mark on glass like the co2 laser marking machine, and this The two types of laser marking machines have different marking effects on glass, and they can also produce good results on ceramic products.

Fourth, green laser marking machine.

The green laser marking machine is of a nature, but the effect is different. For example, the effect of marking on glass is green font, and the same is true for ceramics. The marking effect of plastic materials is also slightly different.

Fifth, end-pumped semiconductor laser marking machine.

The end-pump semiconductor laser marking machine belongs to a light-transmitting key laser marking machine, which is mainly used for car key marking, light-transmitting key marking of some electronic products, etc. , Although the fiber laser marking machine can also achieve transparent marking for some products, the marking effect is far from the effect of the end-pumped semiconductor laser marking machine.
