Laser power supply

The laser power supply of optical fiber laser marking machine is a device which provides power for the fiber laser, and its input voltage is ac220v alternating current. Installed in the Marking Machine control box.

Fiber lasers

Optical fiber laser marking machine adopts imported pulse fiber laser, its output laser mode is long, and is designed and installed in the casing of marking machine.

Vibration Mirror Scanning System

The vibration mirror scanning system is composed of two parts, optical scanner and servo control. The whole system is designed and manufactured by new technology, new material, technology and working principle.

The optical scanner adopts the servo motor with the moving magnetic deflection working mode. The utility model has the advantages of large scanning angle, large peak torque, large load inertia, small electromechanical time constant, fast working speed and stable and reliable. The precision bearing clearance mechanism provides ultra bottom axial and radial runout error; the electronic torsion bar "replaces the traditional elastic material torsion bar, greatly enhances the service life and the long-term work reliability;" Any position 0 power maintenance principle not only reduces the use power consumption, but also reduces the device the heating effect, eliminates the thermostat device Advanced high stability Precision position detection sensing technology provides high linearity, high resolution, high repeatability, low drift performance.

The optical scanner is divided into X-directional scanning system and Y-direction scanning system, and each servo motor shaft is fixed with a laser reflective lens. Each servo motor emits digital signals from the computer to control its scanning trajectory respectively.

Focus System

The function of the focusing system is to focus the parallel laser beam on a point. The main use of f-θ lenses, different f-θ lenses of different focal lengths, marking the effect and range is not the same, optical fiber laser marking machine selection of imported high-performance focusing system, the standard configuration of the lens focal length f=160mm, effective scanning range φ110mm. The user can choose the type of lens according to the need.

Optional f-θ lenses are:

f=100mm, effective focus range φ65mm.

f=160mm, effective focus range φ110mm.

Computer control System

Computer control system is the center of Control and command of the whole laser marking machine, and also the carrier of software installation. Through the coordinated control of acousto-optic modulation system and mirror scanning system, the workpiece marking process is finished.

The computer control system of optical fiber laser marking machine mainly includes chassis, motherboard, CPU, hard disk, memory, d/a card, floppy drive, monitor, keyboard, mouse, etc.
