Equipment Introduction:
The JunChuang Laser® UV Laser Marking Machine is developed using a 355nm UV laser. The UV light has an extremely small focused spot, which greatly reduces mechanical deformation of materials and has a small thermal impact during processing. It uses a semiconductor laser pump and undergoes triple frequency doubling within the optical resonant cavity to output a 355nm wavelength laser, with high electro-optic conversion efficiency. The beam quality is TEM00 mode. The accuracy is <5μRad. The maximum speed reaches 1200MM/S.

This equipment uses JunChuang's® exclusively developed laser waveband interception module to intercept and filter out harmonic waves and unstable wavebands in AC and DC power. It inputs and adjusts stable current wavebands to maintain the stability of the laser marking machine. Through JunChuang Laser's® exclusive technology enhancements and adjustments, this equipment offers more stable and durable performance than conventional laser marking machines. JunChuang® industrial laser marking machines are manufactured according to industrial production standards and can operate continuously for 24 hours without interruption. The laser power fluctuation is <2%, power consumption is stable, the laser motion tracking trajectory error is ≤110us, and the repeated positioning accuracy is <5μRad. The operating temperature limit is -5°C to +60°C.

Explanation of Galvanometer Principles:
A galvanometer is a special oscillating motor. The principle is that a energized coil generates torque in a magnetic field. Unlike a rotating motor, its rotor applies a restoring torque through the electromagnetic field, proportional to the angle by which the rotor deviates from the equilibrium position. When a current passes through the coil, the rotor deflects to a certain angle where the electromagnetic torque and restoring torque are equal. Therefore, it cannot rotate like an ordinary motor but can only deflect, with the deflection angle proportional to the current.

Control Circuit Principle:
When an input position signal is received, the motor will oscillate to a certain angle according to the conversion ratio between voltage and angle
