Introduction to the types and working principle of 5W UV laser marking machine

Laser marking machines are still widely used in the current manufacturing industry. Laser marking machines can be classified into many types according to specific applications. Different types of laser marking machines have different working principles. Today we will learn about laser marking. Introduction to the types and working principle of the machine.

UV laser marking machine

Let’s first talk about the UV laser marking machine. The UV laser marking machine is a laser marking machine series. Therefore, its working principle is similar to that of the laser marking machine. It uses laser beams to permanently mark the surface of various materials. mark. It is used to deal with objects with relatively hard surfaces. At the same time, we should also see that the effect of its marking is to directly break the molecular chain of the substance through the short-wavelength laser (different from the evaporation of the surface substance produced by the long-wave laser to expose the deep substance). Draw out the patterns and texts that need to be etched. In fact, this craft is relatively common in our daily lives. It can also be seen that with the advancement of technology, its accuracy and completeness are gradually becoming more real, so it is still worthy of the work of engraving pictures and texts. The person considered.

co2 laser marking machine

The second is the co2 laser marking machine, which has a completely different working principle from the ultraviolet laser marking machine. The carbon dioxide laser marking machine is the carbon dioxide laser marking machine, which is a laser galvanometer marking machine that uses carbon dioxide gas as the working medium. . The carbon dioxide laser uses carbon dioxide gas as the medium. Carbon dioxide and other auxiliary gases are charged into the discharge tube and high voltage is applied to the electrode. Glow discharge is generated in the discharge tube, and the gas is released by the laser for cutting.

Fiber laser marking machine

The third is a fiber laser marking machine. The so-called fiber laser marking machine means that the marking machine uses a fiber laser. The fiber laser has a small size (no water cooling device, air cooling) and good beam quality (fundamental mode). ), maintenance-free and other features. At the same time, we should also be able to see that fiber lasers have become a hot topic in laser physics research, and they are unanimously regarded as a new generation of products that completely replace solid-state lasers. It is mainly composed of three parts: laser, vibrating lens, and marking card. The marking machine that uses fiber laser to produce laser has good beam quality. The life of the whole machine is about 100,000 hours, which is longer than other types of laser markers. The electro-optical conversion efficiency is more than 28%. Compared with other types of laser marking machines, the conversion efficiency of 2%-10% has a great advantage, and it has outstanding performance in energy saving and environmental protection.

laser cutter

The fourth is a laser cutting machine. To put it bluntly, it is the beginning of a project. In front of a piece of "rough stone", laser cutting is to use the laser or direct light emitted from the laser to focus it into high power through the optical path system. Density of the laser beam. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, and the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material will eventually form a slit, so as to achieve the purpose of cutting. Let the general prototype of the work be displayed, so that the rest can be refined.

Nanosecond UV Laser

The above is an introduction to the types and working principles of laser marking machines. I hope that it will be helpful for the majority of users before purchasing laser marking machines.
