Laser Head

The product has an external servo motor built-in drive unit, which drives the focus mirror to change position automatically within about 22mm through a linear mechanism. The user can set continuous focus through the program to complete rapid perforation of thick plates and automatic cutting of plates of different thickness and materials.

Features of laser head

1. Optimized optical configuration and smooth and efficient airflow design.

2. Auto-focusing range +10~-12mm, adjustment accuracy 0.05mm.

3. All lines and air tubes are routed from inside to avoid unnecessary collision and damage.

4. Focusing lens drive maximum acceleration 10m/s², maximum speed 10m/min.

5. Adopt drawer type mirror holder, which makes protecting the lens more quickly and easily.

6. Adopt compound lens for collimation and focusing to get the best optical quality and cutting effect.

7. With QBH, QD, QCS, PAPI, LLK-D and other fiber interfaces can be adapted with various fiber lasers.

Advantages of laser head

● High adaptability: It has a variety of fiber interfaces such as QBH and QCS, which can be adapted to various mainstream lasers.

● Excellent design: Optimized optical configuration and smooth and efficient airflow design significantly improve cutting quality and efficiency.

● Slender nozzle design: Modular, slender nozzle design reduces workpiece interference.

● Exquisite structure: extremely light weight and small size, which reduces the load requirements of the robot and improves the cutting speed and quality.

Structure function of laser head

The laser head consists of four basic units such as collimation module, focus drive module, protection mirror module and nozzle.

1. Collimation module: to complete the fiber collimation function, the incident laser collimated into a parallel beam and has a centering function.

2. Focusing drive module: focus the collimated beam into a high power density converging beam, and achieve automatic adjustment of the focus position through the drive device.

3. Protective lens module: The protective lens can protect the focusing lens from the damage of returning slag and prolong the service life of the focusing lens.

4. Nozzle module: guide the converging beam to the processing workpiece and generate high speed airflow to jet the cutting slit to complete high quality cutting.
