Common Troubleshooting on Laser Marking Machine
Laser marking is widely used in various fields due to its high flexibility and high efficiency. Therefore, the laser marking machine has been widely used. During the use of the laser marking machine, problems may still occur due to improper use, aging of the machine itself, etc. This article briefly analyzes the common troubleshooting solutions for laser marking machines, so that users can make the laser marking machine more durable and extend its service life.
First, laser light unstable.
Laser light instability can cause the laser marking effect to be affected, and it needs to be adjusted in time. The reasons for this may be as follows:
1. The power supply is unstable, which causes the current to be unstable, causing the instability of the laser light. In this case, a good quality power supply module needs to be used.
2. The transmission speed of the scan galvanometer may be too fast, which causes the light spot to be distorted or blurred, resulting in an unstable laser light. At this time, the scan speed needs to be adjusted.
3. The reflected light is caused by the marking surface material or the old or uncleaned material residue, which also causes instability of the laser light. At this time, the material should be cleaned or the residue should be cleaned.
Second, the laser marking quality is poor.
The poor laser marking quality generally indicates that the power of the laser is too weak or the scan speed is too slow, so the control parameters need to be adjusted in time. First of all, the scan speed needs to be adjusted to the appropriate level, and the scanning range must be slightly larger than the marking range, so that the light spot can be fully scanned. In addition, if the power of the laser is too low, the user can adjust the current of the laser power supply to the correct level.
Third, the laser power attenuates.
The main causes of laser power attenuation are:
1. The voltage of the power supply module is too low, or the voltage drops or other problems occur. In this case, the power of the laser needs to be adjusted again;
2. If the focus lens is blurred, distorted or contaminated, the laser power will be attenuated. In this case, the focus lens needs to be cleaned;
3. The laser tube is damaged or aging. The laser tube needs to be replaced in this case.
Finally, the laser marking machine does not mark.
Generally, the following problems can cause it:
1. The connection is loose and the signal is interrupted. This can be solved by checking the connection and re-establishing the signal;
2. The program settings are wrong, or the program is missing. In this case, the program settings need to be re-checked, or the program is repeated;
3. Insufficient supply voltage. This problem can be solved by adjusting the voltage to the correct position.
In summary, judging the cause of the problem and taking corresponding measures are the main ways to solve the problems encountered in laser marking machines. Proper use, timely detection and maintenance of the related parameters of the laser marking machine, and maintenance and calibration of the machine in time are the main ways to extend its service life.
