Structure And Working Principle of CO2 Laser Engaging And Cutting Machine

The characteristic of CO2 laser engaging and cutting machine is to use the laser to process materials. It can be used not only in the advertising industry but also in various packaging industries. Today, let’s talk about the structure and working principle of CO2 laser engaging and cutting machine.

The CO2 laser engaging and cutting machine uses CO2 gas to fill the discharge tube as the medium for generating the laser. When a high voltage is applied to the electrode, the discharge in the discharge tube can make the gas molecules release laser light. After the laser energy is amplified, the machine forms a laser beam for processing materials. Then the laser beam is changed by a computer-controlled vibrating mirror to realize automatic engraving of materials. That is, the laser beam irradiates the surface of the material to instantly convert light energy into heat energy. This process makes the surface of wood materials melt or even vaporize instantly, thus carving to form marks.

This is the core accessory of the CO2 laser engaging and cutting machine. It is a device for generating a laser light source. Generally, it is designed and installed in the case of an engraving machine.

The function of the focusing device is to focus the parallel laser beam on one point.

The scanning system consists of an optical scanner and servo control.

The optical scanner and servo control systems work together to realize X, Y, and Z axis movement. The machine adopts a servo motor with moving magnetic deflection working mode. And each servo motor shaft is fixed with a laser reflector. The computer sends a digital signal to control the servo motor to scan the trajectory.

The computer control system is the center of the whole CO2 laser engaging and cutting machine command. At the same time, it is also the carrier of software running. Through the coordination of an optic modulation system and a galvanometer scanning system, it controls the machine to mark the workpiece.

The laser power supply is a device that provides power for lasers. Generally, it is installed in the control box of the engraving machine.

The CO2 laser engaging and cutting machine consists of the control system, the scanning system, the focusing system, and the protection system. It adopts the most advanced numerical control mode to realize multi-axis linkage and the laser is not affected by speed. At the same time, it adopts an imported servo motor and transmission guide structure with superior performance. Therefore, it can achieve good motion accuracy at high speed.
