Laser marking machine occasionally have problems, if you can not solve the problem in a timely manner may affect the delivery time of the product, although the laser marking machine repair is more troublesome, but the principle is very simple, and there are a number of problems we can solve ourselves.
Fault 1: laser intensity drops, marking is not clear enough
Solution:
1, whether the laser resonant cavity changes. Fine-tune the resonant cavity lens. Make the output spot best.
2, acousto-optic crystal offset or acousto-optic source output energy is low. Adjust the position of the acousto-optic crystal or increase the operating current of the acousto-optic power source.
3, into the galvanometer laser off-center: adjust the laser.
4, if the current is adjusted to 20A or so still feel the light is not strong enough: krypton lamp aging, replace the new lamp.
Fault 2: krypton lamp can not be triggered
Solution:
1, check all the power connections.
2, high pressure krypton lamp aging, replace the krypton lamp.
Fault 3: online with a long and three short alarm
There are several reasons and troubleshooting methods:
1, the software does not work, the motherboard is loose, open the computer please re-insert.
2, Q drive alarm light is on, check the 37 pin and 15 pin there is no loose, Q switch there is no normal water.
3, laser power alarm light is on, check the chiller is not open, there is no damage to the lamp, (such as damage to the lamp needs to be replaced).
Failure 4: not out of the light of the reason
There are several reasons and solutions:
1, the machine optical screws loose, need to tighten the screws.
2, whether too much dust in the gun body, in case of injury to the gun mirror, if found must replace the gun mirror.
3, the chiller is not open for a long time when the laser power supply light will cause icing out of the light phenomenon, you need to turn off the entire power system 1 hour and then reboot.
4, lamp aging or laser power decline, must replace the lamp.
5, after a long time of work, the laser power decline, open the bottom cover of the gun body, need to do in the gun inside the mirror to adjust.
Failure 5: computer common problems
There are the following kinds of problems:
1, the processing of the graphics is complex, must be checked.
2, on-line computer do not connect to the network cable, it is a separate control laser system.
3, running slowly, this time, please never be too impatient, so as not to die.
4, please pay attention to prevent viruses, in order to prevent the system error.
Fault 6: table XY axis is not allowed
1, table slide screws are loose.
2, the glass on the table with the customer's requirements to determine, can be replaced with iron or plexiglass plate, glass can be adjusted below the role of balance.
3, the right side of the table and the upper and lower corners of the electronic ruler can be installed, you can do a good job of electronic ruler installation to facilitate the needs of customers.
4, the screw holes on the table can be convenient for customers to locate with, negated by the product.
Fault 7: jumping when running, and the position is roughly fixed
The following reasons and troubleshooting methods:
1, the synchronous belt stretch too long deformation ----- replace the new synchronous belt.
2, the size of the wheel reducer wheel device pinion groove has dirt ----- clean pinion groove dirt.
3, drive shaft pinion gear has dirt ----- clean drive shaft gear slot dirt.
Fault 8: Closed line start and end points are not closed
There are several reasons:
1, the synchronous belt is too loose ----- tighten the synchronous belt.
2, the connection between the gear and the shaft is loose ----- retighten.
3, X-axis guide and Y-axis guide are not perpendicular ----- Adjust the perpendicularity of X, Y-axis guide.
4, the slider and guide rail clearance ----- replace the slider.
Fault 9: If you encounter cut through the situation
There are several reasons and troubleshooting methods:
1, vertical light is not correct - adjust the vertical light, if necessary, can be re-adjusted to the light path.
2, improperly adjusted focus ---- readjust the focus.
3, voltage instability, lower voltage laser current is too small to replace the larger voltage regulator, increase the laser current output.
4, the gas nozzle out of the light mouth is blocked by sputtering ---- clean up the gas nozzle.
5, the protective gas does not work --- clean up the air pump, air filter, check the air circulation path.
6, reflector and focusing lens is contaminated ---- with cleaning solution to clean the reflector, focusing lens.
7, the laser tube power drops ---- replace the laser tube.
8, the motherboard out of the light control module failure --- replace the motherboard.
9, there is a potentiometer device, the potentiometer setting is too small or its own failure - adjust the potentiometer setting or replace the potentiometer.
10, the energy setting in the software is too small ---- boost energy.
11, material problems ---- please choose the right material
12, focusing lens cracked or poor focusing ---- replace the focusing lens.
13, too much dirt in the laser tube heat dissipation effect is poor ---- choose pure water.
Two, laser marking machine how to maintain and repair
1, first of all, the vibrating mirror. Avoid close to strong magnetism, strong electricity, strong vibration flow items, avoid hands and items touching the vibrating mirror. If the lens has dust, you can use a rag with a small amount of alcohol to clean, pay attention to rub along a direction.
2, chassis in the laser: regular cleaning dust, with an air gun along the direction of the air duct blowing, while cleaning the relevant circuit board. Air gun is a good tool, you can also clean the laser chiller it.
3, check whether the equipment grounding is secure, the power cord and plug intact, in order to avoid leakage accidents.
4, lifting machinery, rails and other moving parts to add lubricant, once a month. Regularly check whether the equipment fan is normal.
5, before use: check whether there is a change in the software settings, the function buttons, indicators are normal.
6, after use: use clean rags to clean the workbench, monitor, keyboard surface, and timely removal of cleanup garbage, especially after marking metal residue or metal powder foam, clean up the peripheral health, maintain ventilation. Note: When shutting down, please turn off the laser power before turning off the marking software, otherwise it will damage the life of the laser.
7, replace the circulating water and clean the water tank: clean up once a week, replace the water inside, inside the circulating water is too long on the machine is not good, the quality of the circulating water and water temperature directly affects the service life of the laser tube, it is recommended that the use of pure water or distilled water, and the water temperature will be controlled at 35 ℃ below.
