Laser Head Maintenance: Cleaning the Lens and Replacing the Krypton Lamp

It explains in detail the daily maintenance routine for the laser head, including cleaning the mirror, checking the state of the krypton lamp, and replacing the lamp.The guide helps users extend the life of their equipment and maintain stability in output, and is especially useful for owners of laser engraving machines and medical laser equipment.

Preparation before daily maintenance.

Before getting started, we must first do two things: Turn off the power and wait half an hour to let the laser head cool down, and get together the tools.I suggest you prepare three essential items: alcohol, lint-free cotton swabs, and anti-static gloves.I've seen many friends use ordinary paper towels to clean their lenses, and end up with scratches that impair the precision of the lenses. This is something to be very careful about.

A complete cleaning process.

Surface dust removal.

He uses a bulb to blow off the dust on the surface of the lens, just as one would do to a camera lens.If you encounter stubborn dust, don't try to scrub it off. Try blowing it off from a different angle.The last time I helped a customer, I discovered that it was more effective to blow at a 45-degree angle.

Deep cleaning techniques.

The cotton swab is dipped in alcohol and the excess is squeezed off.Be sure to draw spiral lines from the center outward, and don't rub back and forth vigorously.Once I saw a beginner rubbing back and forth horizontally and he ended up scratching the coating. That lesson must be remembered.

Changing the krypton bulb.

Points to note when dismantling an old lamp tube.

Wearing an anti-static glove, she carefully twists the ceramic base to remove it.If both ends of the electrodes become blackened, the printed circuit board may also be at fault.We've had customers who've had new lamps installed, but they still don't work. In the end, it turns out that the driver has failed.

New tube installation techniques.

Make sure that the card is properly aligned with the slot. Don't force the card in.After you have assembled the bulb, don't be in a hurry to screw the outer glass on. When you test it with electricity, the spots should be evenly distributed.When we were debugging a factory, we discovered that by adjusting the angle by 2 millimeters, we could increase output by 15 %.

Checklist for post-maintenance inspection.

Finally, don't forget to do the following three tests: after the machine has warmed up, check that the cooling fan is working properly; use test paper to check the laser focus; and monitor the temperature after 20 minutes of continuous operation.He recommends that all users set aside a certain day each month for maintenance, as a good habit can prevent many breakdowns.
