Introduction to the structure of the 532nm green laser marking machine

The laser marking machine is currently being used in our current social environment. Whether it is for a company or a private enterprise, we should be aware of what types of structure are divided into when buying or using the laser marking machine. , It is also helpful for us to check the problem of the machine in the process of use.

532 nanosecond laser marking machine

The structure of the laser marking machine is divided into a laser power supply, a green laser, a galvanometer scanning system, a gathering system, and a computer control system.

Laser power supply

1. Laser power supply. The laser power supply of the green laser marking machine is a device that provides power for the green laser. Installed in the control box of the marking machine.

Green laser

2. Green laser. The green laser marking machine adopts imported pulsed green laser, which has a good output laser mode and long service life. It is designed to be installed in the casing of the marking machine.

Galvo scanning system

3. Galvo scanning system. The galvanometer scanning system is composed of two parts: an optical scanner and a servo control. The entire system is designed and manufactured with new technologies, new materials, new processes, and new working principles. The optical scanner adopts a servo motor with a moving magnetic deflection working mode. It has the advantages of large scanning angle, large peak torque, large load inertia, small electromechanical time constant, fast working speed, stability and reliability, etc. The precision bearing anti-backlash mechanism provides ultra-bottom axial and radial runout errors; "electronic torsion bar" replaces the traditional elastic material torsion bar, which greatly improves the service life and long-term reliability; the working principle of zero power maintenance at any position is reduced The power consumption is reduced, the heating effect of the laser marking machine components is reduced, and the constant temperature device is omitted; the advanced high stability and precision position detection sensor technology provides high linearity, high resolution, high repeatability, and low drift performance . The optical scanner is divided into an X-direction scanning system and a Y-direction scanning system, and a laser reflection mirror is fixed on each servo motor shaft. Each servo motor is controlled by a digital signal from the computer to control its scanning trajectory.

Aggregation system

4. Aggregation system. The function of the focusing system is to focus the parallel laser beams at one point. The f-θ lens is mainly used. The focal length of different f-θ lenses is different, and the marking effect and range are different. The fiber laser marking machine uses an imported high-performance focusing system. The standard lens focal length f=160mm, effective scanning The range is Φ110mm. The user can choose the lens of the model according to the need.

Computer control system

5. Computer control system. The computer control system is the center of control and command of the entire laser marking machine. It can be understood as the human brain and also the carrier of software installation. Through the coordinated control of the acousto-optic modulation system and the galvanometer scanning system, the marking of the workpiece is completed.

The five points mentioned above are an introduction to the internal and external structure and system of the laser marking machine. At the same time, it also introduces the characteristics of each structure, and also explains the usage instructions of each structure and system. I hope to help you.
