How to solve the problem of laser marking machine not producing laser？

Laser marking machine is a widely used equipment in people's lives. All kinds of food bags, bottles and clothes in life will be marked. It is an essential equipment for OEM factories. However, laser marking machine will also have some faults in the long-term use process, such as laser marking machine not producing laser. Faced with such a situation, many people don't know how to deal with it, and they are also very anxious. How to solve the problem of laser marking machine not producing laser? Let's introduce it in detail below.

How to solve the problem of laser marking machine not producing laser

1. In the basic parameters of the laser marking machine, check whether the type of laser is appropriate. This is also the main reason for the failure of continuous lighting.

2. Drive the nine-core control line of the laser marking machine, check and observe whether the control line is loose and whether the connection is unreliable.

3. Remove the control line on the power supply of the laser marking machine, that is, the nine copper wires. Then, according to the sending key of the laser power supply, we can judge whether it is a power supply failure or a motherboard failure.

4. If the aiming is normal, it means that the power supply of the laser marking machine is normal and there is no problem.

5. If the photo is abnormal, it means there is something wrong with the power supply.

6. When the power supply is normal, you can connect the control line, and then use a multimeter to measure the power switch on the junction box to control the pin. If the laser marking machine does not light up and the normal working voltage is higher than 4V, if it is less than 3V, the motherboard output is abnormal. When it is lit, the working voltage should be less than 2 volts. If it is higher than 2.5 volts, the output is abnormal.

7. Check whether the water circulation system of the laser marking machine is abnormal, whether the water output is sometimes abnormal, and whether the water protection device is OK.

The laser marking machine can usually be checked through the above situations if it does not work through the above methods. If it cannot be solved, the only way is to replace the equipment. Among them, the laser marking machine developed by SAN Laser is cost-effective, quality guaranteed, and advanced in the industry. It will have a significant improvement in accuracy and efficiency in all aspects, and there is also a complete after-sales service. If there is a problem with the equipment, it can be solved as soon as possible.
