Three-In-One Laser Welding Machine Troubleshooting

Cause Analysis:

If the use time is too long, the astigmatism is serious when the focus is not welded, and the laser deviation may occur.

Solution:

Make sure before handling

①The red light is centered (polarized light will cause the light to hit the mouthpiece)

②Appropriate scan width (usually within 5, usually set to 3)

③The focus is 0 focal point (the scale tube can be set to 0)

1. First, emit light to the ground from a long distance, and check whether the copper nozzle is hot. If it is not hot, it means that there is no problem with the lens, and there is no astigmatism. If it is hot, the damaged lens needs to be replaced .

2. If the welding is hot under the above normal conditions, it means that the material conducts heat during welding. In actual use, the outer corner copper nozzle is more likely to be damaged than the inner corner, and red copper copper nozzles can be used .

3. The welding method also affects the heat, try to weld the welding head and the material at 45°∠ welding .

4. Highly reflective materials such as aluminum plates will also cause the copper nozzle to become hot, which is uncontrollable .

Solving the problem of the welding head: the processing of abnormal motor wobble (line change point)

The normal light spot becomes a light spot line (left) by wobbling the motor. If the motor does not wobble, a dot will be displayed (right).

Cause Analysis:

1. Whether the software part is set correctly

Settings - Scan Correction: 1.25

Process - Scan Width: Welding System 3-5,

Home-Indication Red Light: On

Hardware part inspection

1. The power supply of the wobble motor is 15V power supply, we should first measure whether the power supply of the 15V switching power supply is normal.

2. In addition, the 15V switching power supply is divided into positive and negative, and the wrong wiring will also cause the motor to not work.

3. Check whether the connectors on both ends are inserted in place.

4. If the power supply is normal, it is usually caused by an open circuit. The control box and the motor are powered by a 2-core wire. Focus on checking the air plug of the 2-core wire, and disassemble it to see if there is an open circuit.

5. When there is no problem with the 2-core cable, check the signal plug of the 5-core cable, and also disassemble it to see if there is an open circuit.
