Introduction to JunChuang Fiber Laser Marking Machine:

The JunChuang® series of marking machines utilize a 10mm incident spot size, providing clear and crack-free text input. The maximum speed reaches 1200MM/S, with a 20W industrial laser as the core power source, offering a lifespan of up to 100,000 hours.

This equipment employs JunChuang's® exclusively developed laser waveband interception module, which can intercept and filter out the harmonics and unstable wavebands in AC and DC power, ensuring a stable current waveband for the laser marking machine. Through JunChuang Laser's® exclusive technology enhancements and tuning, this equipment exhibits greater stability and durability compared to conventional laser marking machines. The JunChuang® industrial laser marking machine is manufactured according to industrial production standards, capable of continuous 24-hour uninterrupted operation, with a laser power fluctuation of ＜2%, stable power consumption, a laser movement tracking error of ≤110us, and a repeat positioning accuracy of ＜5μRad. The operating temperature range is from -15°C to +60°C.

Fiber laser marking machines utilize a laser beam to create marks on various material surfaces. The marking effect is achieved by evaporating the surface material to reveal the deeper layer, or causing physical changes in the surface material through optical energy to "etch" traces, or burning away part of the material to expose the desired etched patterns, text, barcodes, and other graphics.

Characteristics of Fiber Laser Marking Machines:

1. Can process a wide range of metallic and non-metallic materials, especially advantageous for marking high-hardness, high-melting-point, and brittle materials.
2. Non-contact processing, which does not damage the product and has no tool wear, resulting in high-quality marking.
3. The laser beam is thin, with minimal material consumption during processing and a small thermally affected zone.
4. High processing efficiency, 2-3 times that of traditional laser marking machines, computer-controlled, and easy to automate.
5. Long lifespan, using a laser diode as the pump source, with an average operating time of up to 100,000 hours.
6. Low operating costs, with an electro-optic conversion efficiency of up to 30% and a total power consumption of less than 500W, which is one-tenth of that of pump-source solid-state laser marking machines, significantly reducing energy consumption expenses.
7. Maintenance-free operation.

Application Fields of Fiber Laser Marking Machines:

Electrical appliances, electronic communications, automotive and motorcycle parts, precision hardware, gift accessories, eyeglasses and watches, instruments and meters, and sanitary ware industries, not suitable for highly reflective materials.

Explanation of Galvo Mechanism:

A galvo is a special oscillating motor. The principle involves generating torque in a magnetic field when a energized coil is energized. Unlike a rotating motor, its rotor applies a restoring torque through the electromagnetic field, which is proportional to the angle by which the rotor deviates from the equilibrium position. When the coil is energized, the rotor deflects to a certain angle, where the electromagnetic torque is equal to the restoring torque, so it cannot rotate like an ordinary motor but can only deflect, and the deflection angle is 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.

The entire process adopts closed-loop feedback control, with the joint action of five major control circuits: position sensors, error amplifiers, power amplifiers, position discriminators, and current integrators.
