1. Laser Power Supply
The laser power supply for the fiber laser marking machine is a device that provides power to the fiber laser. Its input voltage is AC220V. It is installed in the marking machine control box.
2. Fiber Laser
The fiber laser marking machine uses an imported pulsed fiber laser, which has a good output laser mode and a long service life. It is designed to be installed inside the marking machine casing.
3. Galvo Scanning System
The galvo scanning system consists of an optical scanner and a servo control part. The entire system is designed and manufactured using new technologies, new materials, new processes, and new working principles.
The optical scanner uses a moving magnet deflection working mode servo motor. It has advantages such as a large scanning angle, high peak torque, large load inertia, small electromechanical time constant, fast working speed, and stability and reliability. The precision bearing clearance compensation mechanism provides ultra-low axial and radial runout errors; the "electronic torque rod" replaces the traditional elastic material torque rod, greatly improving service life and long-term working reliability; the zero-power holding working principle at any position reduces power consumption and minimizes the heating effect of the device, eliminating the need for a constant temperature device; advanced high-stability precision position detection sensor technology provides high linearity, high resolution, high repeatability, and low drift performance.
The optical scanner is divided into X-direction scanning system and Y-direction scanning system, with laser mirrors fixed on each servo motor shaft. Each servo motor is controlled by digital signals sent from the computer to determine its scanning trajectory.
4. Focusing System
The role of the focusing system is to concentrate parallel laser beams onto a single point. It primarily utilizes f-θ lenses, which vary in focal lengths, leading to different marking effects and ranges. The fiber laser marking machine is equipped with an imported high-performance focusing system, featuring a standard lens focal length of f=160mm and an effective scanning range of Φ110mm. Users can select lens models based on their requirements.
The optional F-θ lenses include:
f=100mm, effective focusing range Φ65mm.
f=160mm, effective focusing range Φ110mm.
5. Computer Control System
The computer control system is the center of control and command for the entire laser marking machine, and it is also the carrier for software installation. It completes the marking process on the workpiece through coordinated control of the acousto-optic modulation system and the galvo scanning system.
The computer control system of the fiber laser marking machine mainly includes the chassis, motherboard, CPU, hard disk, memory, D/A card, floppy drive, monitor, keyboard, mouse, etc.
This is about what systems make up a laser marking machine. What are your thoughts? Feel free to share in the comments for discussion!
