How to solve the problem of laser marking machine?

Fault 1: The laser intensity of the laser marking machine is reduced, and the marking is not clear enough

Solution:

① Whether the laser cavity changes; fine-tune the cavity lens. Make the output light spot the best;

② The acousto-optic crystal is shifted or the output power of the acousto-optic power is low; adjust the position of the acousto-optic crystal or increase the working current of the acousto-optic power

③ The laser entering the galvanometer is off-center: adjust the laser;

④ If the current is adjusted to about 20A, the sensitivity is still not enough: the lamp is aging, replace it with a new one.

Fault 2: The 氪 light cannot be triggered

Solution:

① Check all power cables;

② The high-pressure cymbal lamp is aging. Replace the cymbal lamp.

Cautions when operating laser marking machine

① It is strictly forbidden to start the laser power supply and Q-switched power supply in the absence of water or abnormal water circulation;

② No-load operation of Q power supply is not allowed (that is, the output end of Q-adjusted power supply is floating);

③If an abnormal phenomenon occurs, first turn off the galvanometer switch and key switch, and then check;

④ It is not allowed to start other components before the cymbal lamp is ignited to prevent high voltage from entering the damaged components;

⑤ Pay attention to the laser power output (anode) floating to prevent fire and breakdown with other electrical appliances;

⑥ Keep the internal circulating water clean. Clean the water tank regularly and replace it with deionized or pure water.
