3. Setup and Installation

The galvanometer motor is designed for straightforward integration into compatible QILIN laser welding guns. Proper installation is crucial for optimal performance and safety.

Installation Steps:

1. Power Disconnection: Ensure the laser welding system is completely powered off and disconnected from the main power supply before beginning installation.
2. Access Welding Head: Carefully open or disassemble the laser welding gun head to access the galvanometer motor compartment. Refer to your specific QILIN welding gun manual for detailed instructions on accessing internal components.
3. Remove Old Motor (if applicable): If replacing an existing motor, gently disconnect its wiring and carefully remove it from its housing. Note the orientation of the old motor.
4. Insert New Motor: Align the new DMK QILIN Galvanometer Motor (X-type) into the designated slot within the welding gun head. Ensure it is seated correctly and securely.
5. Connect Wiring: Connect the motor's wiring harness to the corresponding port on the welding gun's control board. Ensure all connections are firm and correctly oriented.
6. Secure Components: Reassemble the welding gun head, ensuring all screws and fasteners are tightened appropriately.
7. Initial Check: Before powering on, visually inspect all connections and ensure no wires are pinched or exposed.

4. Operating Principles

The galvanometer motor is an electromechanical device that precisely controls the angle of a small mirror. In a laser welding gun, this mirror reflects and directs the laser beam. By rapidly and accurately changing the mirror's angle, the galvanometer motor enables the laser beam to scan across the workpiece, creating the desired weld path.

The X-axis motor controls the horizontal movement of the laser beam, while a Y-axis motor (if present) controls the vertical movement. Together, they allow for two-dimensional scanning and precise positioning of the laser spot during welding operations. The motor receives control signals from the laser welding system's main controller, translating these signals into precise angular displacements of the mirror.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your DMK QILIN Galvanometer Motor. Always ensure the laser welding system is powered off and disconnected before performing any maintenance.

Maintenance Guidelines:

• Cleaning: Periodically inspect the motor's mirror for dust, debris, or contaminants. Use a specialized optical cleaning solution and lint-free wipes to gently clean the mirror surface. Avoid touching the mirror with bare hands.
• Connection Check: Regularly inspect all electrical connections for tightness and signs of wear or corrosion. Ensure the wiring harness is not damaged or frayed.
• Environmental Control: Operate the laser welding system in a clean, dry environment, free from excessive dust, humidity, and extreme temperatures, which can negatively impact the motor's performance and lifespan.
• Avoid Impact: The galvanometer motor is a precision instrument. Avoid dropping or subjecting the welding gun to harsh impacts, as this can damage the motor or misalign the mirror.
• Professional Inspection: For complex issues or internal cleaning, it is recommended to seek assistance from qualified service personnel.

6. Troubleshooting

This section provides basic troubleshooting steps for common issues related to the galvanometer motor. For more complex problems, consult a qualified technician.

Common Issues and Solutions:

• Issue: Laser beam movement is erratic or inaccurate.
  Solution:
  1. Check for debris or smudges on the galvanometer mirror and clean if necessary.
  2. Ensure all wiring connections to the motor are secure.
  3. Verify that the motor is correctly seated in its housing.
  4. Consult the laser welding system's main control unit for error codes or calibration issues.
• Issue: Motor is not responding or moving.
  Solution:
  1. Confirm the laser welding system is powered on and receiving power.
  2. Check the motor's wiring harness for any disconnections or damage.
  3. If replacing a motor, ensure the correct X or Y type motor is installed in the appropriate axis.
  4. If the issue persists, the motor may be faulty and require replacement.
• Issue: Unusual noises from the motor.
  Solution:
  1. Power off the system immediately.
  2. Inspect the motor for any physical obstructions or signs of internal damage.
  3. Contact technical support for further diagnosis.
