Fiber Laser Marking Machine Troubleshooting Summary

Fiber laser marking machines are widely employed for graphic and textual marking across various sectors, encompassing integrated circuit chips, computer peripherals, industrial bearings, clocks, electronic and communication products, aerospace components, diverse automotive parts, household appliances, hardware tools, molds, wires, and also for cable, food packaging, jewelry, tobacco, military, and large-scale production line operations.

 

Fiber Laser Marking Machine Troubleshooting Summary:

1.Deviation from the focal point during marking, due to the differing focal depth range of each focusing lens, can lead to edges being at the critical point of the focal depth or exceeding the focal depth range, resulting in uneven effects, especially with larger pattern ranges. Therefore, the pad printing marking method must consider the issue of laser energy.

2.Improper adjustment of the laser output head, fixed fixtures, and vibration mirrors may cause partial spots to be obstructed when the laser passes through the vibration mirror. After focusing by the field lens, the spot on the frequency doubler may be non-circular, which could also lead to uneven effects. Another scenario is when the reflection mirror is damaged during the deflection of the vibration mirror, causing the laser beam to reflect poorly through the damaged area of the reflection mirror. However, there is a difference in laser energy between the damaged and undamaged areas of the mirror, resulting in different laser energy acting on the material and leading to uneven marking effects.

 

3.When the laser passes through optical lenses (refractive, reflective), the lenses heat up, causing slight deformation and resulting in the laser focus rising and the focal length shortening. If the machine is fixed, adjusting to the focal distance, and the laser is opened for a period of time, the phenomenon of thermal lensing may cause changes in the laser energy density acting on the material, resulting in uneven marking effects.
