Laser marking is the use of a laser beam to mark permanent surfaces on a variety of different materials. The effect of marking is to expose deep substances by evaporation of surface substances, or to "engraving" traces by chemical or physical changes of surface substances caused by light energy, or to burn off some substances by light energy to show the desired etching.

Composition

Laser power supply

The fiber laser marking machine laser power supply is a device that powers the fiber laser, and its input voltage is AC220V AC. Installed in the marking machine control box.

fiber-optic laser

The fiber laser marking machine adopts imported pulsed fiber laser, and its output laser mode has a long service life and is designed and installed in the casing of the marking machine.

Galvanometer scanning system

The galvanometer scanning system consists of two parts: an optical scanner and servo control. The entire system is designed and manufactured using new technologies, new materials, new processes, and new working principles.

The optical scanner uses a servo motor with a moving magnetic deflection mode. The utility model has the advantages of large scanning angle, large peak torque, large load inertia, small electromechanical time constant, fast working speed, stable and reliable, and the like. The precision bearing anti-backlash mechanism provides the ultra-bottom axial and radial runout error; the “Electronic Torque Bar” replaces the traditional elastic material torsion bar, which greatly improves the service life and long-term reliability; the zero-power retention operation at any position reduces the working principle. The use of power consumption reduces the heating effect of the device, eliminating the need for thermostats; advanced high-stability precision position sensing sensing 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 reflecting lens is fixed on each servo motor shaft. Each servo motor is digitally controlled by a computer to control its scanning trajectory.

Focusing system

The function of the focusing system is to focus the parallel laser beam at one point. Mainly adopt f-θ lens, the focal length of different f-θ lenses is different, the marking effect and range are different. The fiber laser marking machine adopts imported high-performance focusing system, and its standard lens focal length f=160mm, effective scanning The range is Φ110mm. Users can choose the model lens as needed.
