The laser marking machine is faulty and I don t know how to repair it

Laser marking machine is the most widely used engraving equipment in the current practical application, although the probability of its failure is very small, but it does not exclude various small problems that occur in the improper operation of the user process or setting problems, in fact, these problems are small faults that can be solved by the user themselves, in order to improve the user's use of the metal laser marking machine, improve production efficiency. The following Shenzhen Bot Laser Technology provides some daily solutions to problems for new and old users.

First, the laser marking machine light is weak:

1. If the focal length is not adjusted well, readjust the focal length.

2. If the CW method of the marking software is not selected, the light will be very weak, so choose the CW method.

3. The cavity, total mirror, semi-reflector and beam expander are not adjusted and re-adjusted.

4. The laser does not hit the center of the galvanometer, or the lens of the galvanometer is scratched. Readjust the optical path, or swap the galvanometer.

5. The lenses of all-reflective or semi-reflective lenses, focusing lenses, galvanometer lenses, and Q switches are dirty or scratched. Wipe clean or replace.

6. The Q switch is not adjusted well, the normal situation is to emit light when marking, and the Q switch should lock the laser when not marking. The current of the laser power supply can be increased by just right, and the frequency doubling sheet can be placed in front of the semi-reflector to see if there is any light leakage. If there is light leakage, the light will be very weak, re-adjust the Q switch.

Second, the laser marking machine can not emit light:

1. The board card is damaged, and the board card is replaced.

2. The Q switch is broken, and the Q switch is replaced.

3. The Q driver is bad, replace the Q driver.

4. If the laser power supply is bad, replace the laser power supply.

5. The optical path is not adjusted well, and the optical path is re-adjusted.

6. Computer manipulation system or computer obstruction, reinstall system or replace computer.

7. The signal connection between the board and the driver is open, and it is replaced or re-soldered.

3. The galvanometer does not move when marking

1. If the galvanometer is damaged, replace the galvanometer.

2. The galvanometer signal line is open and replaced.

3. The computer manipulates the system or the computer obstructs, reinstalls the system or replaces the computer.

4. The jumper cap next to the signal indicator on the driver must be lost, otherwise the galvanometer will not move.

5. The parameter x and y proportional adjustment options on the software are zero, and the galvanometer will not move and re-adjust the parameters.

Fourth, the marking effect is not ideal

1. The parameters of the marking software are not adjusted well, and the parameters are re-adjusted.

2. The reason for the marking software or system. Reinstall the system or marking software.

3. The marking graphics are not done well or the marking materials are not possible.

4. If the focal length is not adjusted well, readjust the focal length.

It depends on the cause of your failure. It's easy to find the fault and repair it.

What failure? Fiber optic or CO2 markers?

First, check the focus of the laser marking machine, whether there is an offset or change, whether the optical path is offset, and carefully adjust the optical path; Whether the mirror of the laser marking machine is polluted or damaged, and whether the reflector is cleaned or replaced; Whether the cooling water circulates normally, secondly, check whether the water quality or water temperature of the cooling water is normal; Whether the power supply of the laser marking machine is energized, if it is not energized, it is necessary to consider whether the laser power supply is damaged and replace the power supply.

Second, on the high-voltage side, the ammeter is connected in series, and it can be seen that the ammeter shows abnormality, either there is a current for a long time, or it comes and goes, and sometimes it is not controlled. The main reasons are the wrong choice of laser type, the connection of the motherboard, power supply or control cable, and the failure of the cooling water circulation system. Exclusion Method:

1..Check to see if the water cycle is normal, if the water flow is coming and going, and if there is a problem with the water protector.

2.Pull the Jiurui control line to see if there is any loose control line. The connection is unreliable.

3.In the parameter setting, check whether the laser type is correct, which is the main cause of continuous luminescence failure.

4.Remove the control cable from the power supply and press the dot fire button of the laser power supply to analyze whether the power supply or the motherboard is faulty.

5.If the spot shot is normal, it means that the power supply is not faulty.

6.The spot shot is also abnormal, indicating that there is a problem with the power supply.

The reason for the problem that the laser marking machine cannot type:

The software laser type is set incorrectly; The optical path is wrong or the focal length is not adjusted properly; The laser power supply is not energized or damaged; The control signal wire is broken or the plug is loose or the control card is broken; The laser is broken.

The laser marking machine can't type the solution:

The laser type is set to CO2; Adjust the optical path to adjust the focal length; There is AC 220V without DC 96V or 115V output laser power supply is bad, there is no AC 220V input check line, whether the AC contactor is engaged, whether the intermediate relay is engaged, and whether the water tank is operating normally; Re-weld the breakpoint, re-insert the joint and tighten the fixing screw, and replace the control card with the fault of the control signal signal; Replace the laser.

In general, we know that the cause of failure can be the following: laser selection error, motherboard failure, power board, power supply or control line connection issues, or cooling water circulation.

System failure. Well, eliminate laser printers.

What are the ways to not get out of the laser:

1.in the laser marking machine.

to check whether the laser type is correct. This is the main cause of continuous luminescence failure.

2.Pull the nine-core control line of the laser marking machine to test and observe whether the control line is loose and whether the connection is unreliable.

3.Remove the control line above the power supply of the laser marking machine, that is, the nine-core wire. Then, according to the emission and response key of the laser power supply, we can judge whether it is a power failure or a motherboard failure.

4.If the spot shot is normal, it means that the power supply of the laser marking machine is normal and there is no fault.

5.If the shooting is not normal, there is a problem with the power supply.

6.When the power supply is normal, you can connect the control cable, and then use a multimeter.

Measuring junction box.

on the switch to control the pins. If the laser marking machine does not emit light and the normal voltage is higher than 4V, if it is lower than 3V, the motherboard output is abnormal. When emitting light, the voltage should be less than 2 volts. If it is higher than volts, the output is abnormal.

7.Check whether the water circulation of the laser marking machine is abnormal, whether the water flow is abnormal from time to time, and whether there is no problem with the water protector.

Usually, most of the reasons why the laser cleaning and punching machine cannot produce laser can be investigated from the above 7 items one by one.

Summary. Hello dear, I'm honored to answer for you! The laser marking machine can not type words may be mainly due to the setting of the parameter data type of the software, the optical path is wrong, the power management is not plugged in or damaged, the control signal line is cut off, the plug is not plugged in, the control card is broken, the laser is broken and other factors

1.Since the management software is wrong to set the parameter data type, we teachers can first look at the different types of equipment we need to buy, if it is carbon dioxide, and then set it to carbon dioxide, optical fiber to optical fiber, and so on. 2.

The reason for the incorrect optical path directly affects the correct and reasonable adjustment of the optical path. 3.If the power supply is unplugged or damaged:

Reconnect the cut-off point. 5.Reasons why the plug is not plugged in:

Reinsert and tighten with a set screw to prevent the student from coming loose again. 6. The reason why different lasers in the enterprise can be damaged data: replace the good laser.

What to do if the laser can't type.

4.The reason why the internal control system signal cuts and rolls off: Reconnect the cut-off point.

5.Reason for not inserting the plug: Reinsert it and tighten it with a fixed screw to prevent the student from loosening it again.

6. The reason why different lasers in the enterprise can be damaged data: replace the good laser.

1. First of all, check whether there is a mistake in operating the laser marking machine, if so, you have to turn it off and restart it to try. 2. Carefully observe what is abnormal in the laser marking equipment. The contents of the anomaly mainly include the following:

The sound of work, such as the sound of the diaphragm, the sound of the control box, the alarm sound of the equipment itself, and the alarm sound of the chiller of the semiconductor laser marking machine, etc.; If the voltage is abnormal, it can be measured by simply using a multimeter, and if the voltage is low, it can also lead to no laser; Whether the computer software and the computer are poisoned, the boot is slow, and the interface is stopped for a long time after booting. 3. On the premise of confirming that there are no problems in the previous two kinds, open the laser cavity, use a dimmer, and see if there is a laser output in the laser output port of Laochangxia in the area under the premise of turning on the laser. If there is a laser, then the problem is none other than the following accessories:

Galvanometers, beam expanders, red photocombiner mirrors, and field mirrors have stupidly picked up problems. If there is no laser, move on to the next step. 4. If there is no laser in the previous step, then there are two possibilities, the first is that there may be a problem with the laser, and the second is that there is a problem with the signal controlling the laser.

A laser marker is a device commonly used in industrial production to permanently mark and mark a wide range of materials. In addition to the problem that the laser marking machine does not produce laser elimination, there are some other common problems and solutions:1

Unsatisfactory marking effect: It may be due to insufficient laser power, inaccurate adjustment of the optical path, and the material is not suitable for laser marking. Try adjusting the laser power, readjusting the optical path, or changing the appropriate marking material.

2.Slow marking speed: It may be due to the low laser power setting, inaccurate optical path adjustment, unreasonable marking parameter setting, etc.

Try increasing the laser power, readjusting the optical path, or optimizing the marking parameters. 3.Uneven marking depth:

It is due to inaccurate adjustment of the optical path, unreasonable setting of marking parameters, uneven surface of the material, etc. Try readjusting the optical path, optimizing the marking parameters, or working on the surface of the material. 4.

The laser marking machine is noisy: it may be due to poor heat dissipation of the laser, fan failure, etc. You can check if the laser cooling system is working properly, clean the fan or replace the faulty part.
