How to identify the cause of failure of UV laser marking machine

When all machines have faults, today we will talk about what faults the UV laser marking machine may encounter during use. There are many reasons for the failure of the UV laser marking machine. It may be due to improper selection of the laser, or it may be due to a failure in the main board, circuit board, power supply or control line connection cooling water circulation system. So how to identify the cause of the UV laser marking machine failure? Let's see how to solve it.

1. Pull the control line of the laser marking machine to see if there is a loose control line and whether the connection is reliable.

2. Check whether the laser is used correctly in the parameter setting. The main reason is the failure of continuous light emission.

3. If the point shooting is normal, it means there is no power failure. On the contrary, the shooting point is abnormal, that is, the power failure.

4. Remove the control line in the power circuit, click the click button of the laser power supply, and analyze the fault caused by the power supply or the mainboard.

5. When the power supply is normal, connect the control line and use a multimeter to measure the switch control pin on the terminal board. There is no light, the normal voltage is greater than 4 volts and less than 3 volts, and the mainboard output is abnormal; when it is lit, the pin voltage should be lower than 2 volts, and the abnormal output should be higher than 2.5 volts.

After the above investigations, the cause of the failure of the UV laser marking machine can be basically determined. After the cause of the failure is clear, the problem can be solved to ensure the normal and efficient operation of the UV laser marking machine.
