Daily Maintenance Guide for UV Laser Markers
Based on actual experience in a precision machining workshop, the article shares the specific steps for daily maintenance and care of a UV laser marking machine, covering key areas such as cleaning the equipment, checking the light path, and replacing consumables. This helps operators extend the life of their equipment and ensure marking accuracy.It is a good reference for technicians and factory managers who seek to improve the stability of their equipment.
Why do you have to do maintenance every day?
The UV marking machine in our workshop may seem to be working well, but it's like a car, and needs to be maintained every day.In the case of precision processing, the requirements for marking accuracy are very high. If there is any dust or a slight misalignment in the optical path, the mark may end up being a blur.The neighboring work team has already tried skipping a lens cleaning for three days. In the end, the lines on the labels were all jagged and the whole day was wasted reworking them.So if you spend 10 minutes a day on maintenance, you can save a lot of time and money on repairs.
We'll walk you through the steps of everyday maintenance.
Clean the exterior of the camera and the lens.
After turning off the computer, use a compressed air canister to blow out the dust from the crevices in the case, and don't use a damp cloth to clean it--moisture is the worst enemy of delicate equipment.Use a special lens paper and wipe the lens in a circular motion, starting in the center.Some old-timers like to use eyeglass cloths, but they leave fibers. We shouldn't take the easy way out.
Inspect the optical path and cooling system.
After removing the back cover, he uses a flashlight to look at the mirrors and lenses, and if he sees any obvious gray spots, he gently wipes them away with a cotton swab.If the fan makes a "squeak-squeak" sound, it's likely that the bearings are dirty.We have to pay special attention to the air vents in summer. Last week, someone in our factory didn't notice that one of the vents was blocked by a label, and the machine overheated and shut down.
They are also used to lubricate moving parts.
Remember to oil the X and Y axis rails every day.Don't use ordinary butter!When you apply it, it should be as thin as toothpaste, because if it is too thick, it will just pick up dust.Remember to empty the waste container. A lot of people forget to do this, and the result is that the machine will get jammed the next time you turn it on.
Testing after maintenance.
Don't be in a hurry to get to work. First, print a test page.Choose a design with a 0.1 mm line and check the edges with a magnifying glass.If the picture is out of focus, check to see if there are fingerprints on the lens.If possible, use a power meter to test the device's laser output. A change of more than ± 5 % means you need to contact the manufacturer.Last time we tested, we found the power output was unstable. It turned out that the cooling tank temperature wasn't set properly, and we almost burned out the galvanometer.
Don't step into those pits.
I've seen people wipe the lens with alcohol, and within three months the coating has flaked off, and then it costs NT $ 8,000 to replace the lens. There are also people who use compressed air to blow the light path, and they end up blowing the aligned lenses out of whack.The most important thing is to make sure the power is off before doing any repairs. Last month a factory burned up a control panel by not turning off the power.Remember to unplug the machine when you do maintenance.
