Analysis of the working principle of different types of laser marking machines

The laser marking machine (laser marking machine) uses a laser beam to make a permanent mark on the surface of a variety of different materials. The effect of marking is to use the evaporation of the surface material to leak deep-level materials, so exquisite patterns, trademark logos and text are carved. Laser marking machines can be divided into: fiber laser marking machine, co2 laser marking machine and ultraviolet Laser marking machine, etc. The current laser marking machine is mainly used in some occasions with finer standards and higher precision. Used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, precision equipment, glasses and watches, jewelry, auto parts, plastic buttons, building materials, PVC pipes, etc.

There are many types of laser marking machines, and the laser marking machines used in each manufacturing industry are also different. Today, Minsheng Laser will introduce the principles of different laser marking machines:

      Principle of co2 laser marking machine: co2 laser marking machine (co2 laser marking machine). It is a laser galvanometer laser marking machine that uses co2 gas as the working medium. The co2 laser marking machine is a co2 laser that uses co2 gas as the medium. The co2 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 releases a laser with a wavelength of 10.64um. After the energy is amplified, scanned by the galvanometer and focused by the F-Theta lens, under the control of the computer and the laser marking control card, the product can be marked with images, text, numbers, and lines on the product according to the customer's standards.

      Advantages of co2 laser marking machine: It adopts co2 laser, which is a universal model, rear focus mode, small size and high degree of integration. This equipment is suitable for laser marking of most non-metallic materials, such as paper packaging, plastic products, label stickers, leather product fabrics, glass ceramics, resin plastics, bamboo and wood products, PCB boards, etc. The co2 laser is a gas laser with a wavelength of 10.64um in the far-infrared light band. The CO2 gas is charged into the discharge tube as the medium for generating laser light. When a high voltage is applied to the electrode, the discharge tube is produced
