Common Problems with Laser Marking Machine Components

He provides practical solutions to common problems, such as cleaning, heat dissipation, and high-frequency interference.It explains how to handle typical problems such as abnormally high laser power, laser misalignment, and communication errors, stresses the importance of matching the correct spare parts and calibration, and provides practical advice on spare parts inventory to help users quickly restore equipment to normal operation and extend the life of spare parts.

Points to note in daily maintenance.

Cleaning and dustproofing.

The mirrors, rails and other components of a laser marking machine are most vulnerable to dust build-up.It is recommended that you use a dust-free cloth and special cleaning fluid to wipe the optical lens once a week, and use a soft brush to clean the tracks of small particles. You can also add some lubricant to the tracks.Don't ever use ordinary paper towels to clean the lenses, as this can scratch them and affect the laser marking.

Heat dissipation system check.

Many problems are caused by overheating. Every two weeks, check to see if the cooling fan is running smoothly, and make sure the vents are not blocked.In summer, when temperatures are high, it's best to add industrial fans to help dissipate the heat, to avoid the laser overheating and shutting down.

High-frequency failure problem analysis.

The laser's intensity suddenly drops.

First check whether the focusing lens is dirty or damaged, and then test whether the laser power output voltage is normal.If the first two problems are ruled out, it may be that the laser tube is aging, and the user should contact the manufacturer to have the actual power output checked.

The marking position is off.

If the pattern doesn't align, first check the galvanometer parameters and then check the screws to see if they are loose.If a rotating worktable is used, be sure to check the positioning accuracy of the fixture at the same time.

The software prompts a communications error.

Poor connection between the data line and the computer accounts for 70 % of the problems of this type. Try reinserting the USB or network cable, and if necessary replace it with a better shielded one.If it still doesn't work, try updating the control card driver.

These are the golden rules of accessory replacement.

Priority to matching models.

When changing the laser tube or mirrors, don't go for the cheap non-genuine parts.The power parameters required by tubes of different power ratings are completely different, and mixing them up could cause the control board to burn out.

Calibration must be done as a complete package.

Don't use newly installed parts right away.For example, after installing a new lens, the focal length must be recalibrated. After replacing the galvanometer motor, the X / Y axis must be readjusted, or the marking accuracy will be affected.

List of spare parts in reserve.

We recommend you keep two sets of lenses, an extra fuse, and a few extra cables with you.If a fragile component suddenly breaks, it can be quickly replaced to prevent the production line from being stalled.Remember to check the status of the spare parts every quarter.
