Common faults of laser marking machine maintenance
Addtime：2021-08-13 Browse times：1331
As a popular anti-counterfeiting identification equipment at this stage, laser marking machine has long been widely recognized by the company's consumers. In normal use, although the defect rate of laser marking machine is low, problems still occur.
Laser marking machine has common disadvantages.
1、 Reasons why the expected marking depth cannot be reached:
Whether the lens surface is polluted;
Whether the optical path adjustment is accurate;
Whether the laser output power reaches the specified value;
Whether the off power of acousto-optic switch meets the requirements;
Whether the position and direction of the beam expander are adjusted accurately;
Whether the output DC voltage of laser power supply 28V decreases, resulting in the decrease of laser output power.
2、 Reasons why the acousto-optic switch cannot switch the laser:
Whether the RF line connection is reliable;
Whether all switches of the power supply are in the correct and reasonable position;
Whether there is dirt on the luminous end face of Q switch;
Whether the RF output power of acousto-optic power supply is normal.
3、 The laser output power is normal, but the laser beam cannot play the marking effect:
Whether the adjustment of optical path system is accurate;
Whether the acousto-optic switch can play a switching effect;
The D / a card controls whether the acousto-optic output signal reaches 5V.
There are many reasons for the power defects of laser marking machine. Do you understand? Improve the structure of the machine itself, make it more reasonable and lighter, and its good maintenance and timely lubrication can improve the mechanical efficiency.
