When using laser marking machine, if there is an abnormality, if the problem cannot be solved in time, it will directly affect the workshop output. The maintenance of laser marking machine is more troublesome, but its principle is relatively simple. Many problems can be solved by yourself without the need for professional technicians. The following Eagle laser tells you about the 5 common fault solutions of laser marking machine.
I. What should I do if the laser marking machine cannot print?
If F2 still cannot mark, it may be a machine failure.
1. The software laser type is set incorrectly;
2. The optical path is incorrect;
3. The laser power supply is not powered or damaged;
4. The control signal line is broken or the plug is loose or the control card is broken;
5. The laser is broken.
Solution: If F2 can be printed, you press F3, then open the port, see the math behind the start of marking, adjust it, 0-15 can be tried one by one, and machines of different brands seem to be different.
II. What should I do if the laser marking machine focus is offset?
Because each focusing mirror corresponds to the range of focal depth, and the use of deviated focus method will easily lead to large-scale marking patterns, the edge is at the critical point of focal depth or exceeds the focal depth range, which is very easy to cause uneven effects. Therefore, the method of defocused marking requires considering the problem of laser energy.
III. The marking pattern of the laser marking machine is partially unclear?
1. Solution: Check whether the thickness of the molded plate is uniform, whether the molding pressure is too small, whether the temperature is too low, and whether the machine accuracy is reduced.
2. Key points of process control: The thickness error of the molded plate should be controlled within 0. O01mm, and the hardness should be maintained at 230-280N/mm. Because the hologram is molded by applying a certain pressure to the molded roller to mold interference fringes, if the hardness of the molded plate is not enough, the internal stress will cause the molded plate to deform or damage during the printing process.
IV. The light output of the laser marking machine is weak?
1. The focal length is not adjusted properly, readjust the focal length.
2. The CW method of the marking software is not selected, the light will be very weak, select the CW method.
3. The cavity, full reflector, half reflector and beam expander are not adjusted properly, readjust them.
4. The laser is not hitting the center of the galvanometer, or the lens of the galvanometer is scratched. Re-adjust the light path, or replace the galvanometer.
5. The full reflector or half reflector lens, focusing lens, galvanometer lens, and Q switch lens are dirty or scratched. Wipe clean or replace.
6. The Q switch is not adjusted properly. Normally, it will emit light during marking, and the Q switch should lock the laser when not marking. You can increase the current of the laser power supply and place the frequency doubling plate in front of the half reflector to see if there is any light leakage. If there is light leakage, the light will be very weak, and readjust the Q switch.
V. Laser marking machine cannot emit light?
1. The board is damaged, replace the board.
2. The Q switch is broken, replace the Q switch.
3. The Q driver is broken, replace the Q driver.
4. The laser power supply is broken, replace the laser power supply.
5. The optical path is not adjusted properly, readjust the optical path.
6. The computer operating system or computer is faulty, reinstall the system or replace the computer.
7. The signal connection between the board and the driver is open, replace or re-weld it.
Well, the above is what we shared this time. I hope that the content of this article can be helpful to you who are using the laser marking machine!
