Common faults and solutions of laser marking machine

The laser marking machine uses a laser beam to make permanent marks on the surface of various materials. The effect of marking is to expose deep material through the clear of surface material, thereby engraving beautiful patterns, trademarks and word.

The laser marking machine occasionally has common faults and solutions of laser marking machine. If the problem cannot be solved in time, it may affect the delivery time of the product. In fact, although the maintenance of the laser marking machine is more troublesome, the principle is very simple, and there are some problems that we can solve by ourselves , Today I will teach you some common problems of laser marking machine and how to solve these problems

firstly：The laser intensity drops and the marking is not clear enough.

Solution: Whether the laser resonant cavity changes; fine-tune the resonant cavity lens. Make the output spot the best; the acousto-optic crystal shifts or the output energy of the acousto-optic power supply is low;so  adjust the position of the acousto-optic crystal or increase the working current of the acousto-optic power supply; the laser entering the galvanometer is off-center: adjust the laser; if the current is adjusted to about 20A Still not strong enough: the krypton lamp is aging, replace with a new one.
secondly：The krypton lamp cannot  trigger .

Solution: Check all power connections; the high-voltage krypton lamp is aging, replace the krypton lamp.
thirdly：There are one long and three short alarms when online.

There are several reasons and troubleshooting methods.

1. The software does not work, and the motherboard is loose. so re-plug the computer when you turn it on.

2. When the Q drive alarm light is on, check whether the 37 pins and 15 pins are loose, and whether the Q switch is properly water.

3. When the laser power alarm light is on, check whether the chiller is turn on and whether the lamp tube is damage.
