Laser marking machine maintenance

Post by lasercutting »

The laser beam output of the machine is invisible high brightness light. A person who is not trained professionally is forbidden to operate the machine.
Machine Using Request:
Environment:Please put the machine into an air conditional room.
Temperature:Please use the machine with temperature 10oC-35oC, dust-off and no corrosive gas environment. Hot weather will disturb the water cooling system to cooling the laser component efficiently, so as to shorten life time of the machine or even damage the key laser components (such as : diode module, mirrors, Q-switch).
Cleanness:Keep all the laser components dry and clean / dust-off.
Humidity Pay attention to the lens and laser diode module when the machine is working in an environment with high humidity, to avoid the lens and laser diode module get fog and became dewy.
Clean Mirror and Lens Use absorbent cotton or water-off ethanol to wipe the “Reflect mirrors “ and “F-theta lens” inside of the laser optical bridge slightly, and make it clean once a week.

Follow same operation step if you found the “Output Mirror” and the “Beam Expander Mirror” get dust or feculence.
Increase Laser Power When the output laser power decreases, please adjust the nut of the laser lens slightly till the output facular is round and bright. The output laser beam has been already adjusted to the best working state before leaving factory.
Follow the operation step strictly Please turn on or off the machine according to the order in the operation manual strictly. The improper operation will shorten the life time of the machine and damage the equipment. The Manufacturer won’t bear the responsibility due to this.
5.2. Day / Week / Year Maintenance:
Maintenance Time Method of Maintenance
Day Maintenance Clean the work table everyday.
Clean all the mirror by alcohol every day.
Ensure there is no dust on the Focus lens glass surface.
Week Maintenance Follow same operation step if you found the outlet lens and the beam expander get dust or feculence.
Month Maintenance Check and Tighten all the wire every week.
Year Maintenance Check all the components in the machine, make sure all these components are in good working condition.

5.3 Familiar Malfunction & Troubleshooting:
1. The indicating lights for the computer, red light and galvanometer can not shine.
1) No power supply input----Check the input power supply again.
2) The switch insert of the power supply become loose.------Insert the switch again firmly.
2.
1).The laser power supply can not be turned on.----Check the water circle state in the water cooling system.
2). The time for turning on is too short.-------Make sure the time for pressing the TEST button is enough.(This time can be confirmed by the large extent deflexion of the index on the pressure meter of the water tank.)
3. The laser output power is not high enough, and the marking is not strong.
1). The position of the optical resonance cavity is changed-----Adjust the nuts of the reflecting lens and output lens slightly.
2). The optical lens and components are dirty.----Clean the optical lens and components.
3). Increase the laser power but the output current does not change a lot.---The laser module is aging, please replace a new one.
4. The marking file is not correct.
1). The set electric level for laser beam output is wrong.---------Reset the effective value.
2). The processing work piece is mis-located.------Fix the work piece firmly.
3). There are some virus in the computer.----Please reset the computer programs.
4). The galvanometer is interfered.------Improve the conditions between shield and the ground.
