How to solve the weak light of laser marking machine

by:Leadtech Coding     2022-01-22

Laser marking machine is an indispensable packaging and marking equipment in the industrial production process. The wider the application, the larger the group of users, and there may be some small problems in the process of laser marking. , last time I introduced the reasons and solutions for the light leakage of the laser marking machine. This time I will share with you how to properly deal with the weak light of the laser marking machine.

The weak light of the laser marking machine means that the intensity decreases. The weak light will cause the marking to be unclear, which will seriously affect the marking effect of the product. Low-light inspection and repair method of laser marking machine:

1. If the current is adjusted to about 20A and the photosensitive intensity is not enough, it proves that the krypton lamp is aging and needs to be replaced urgently;


2. Measure whether the laser entering the galvanometer is off-center and adjust the laser;

3. Check whether the laser resonator occurs

4. Check whether the marking software is set correctly, and whether the CW mode light output or the light output efficiency adjustment has been set.

5. Check whether the acousto-optic crystal offset or the output energy of the acousto-optic power supply is low, adjust the position of the acousto-optic crystal or increase the working current of the acousto-optic power supply;

6. Check whether the Q switch and the power supply are faulty. You can remove the Q switch and adjust the light separately to check the intensity. If the Q switch is faulty, replace it directly. .

The above is about the method of low-light inspection and repair of laser marking machine. , please take appropriate preventive measures in time.
