How to solve the shallow depth of 15w high power uv laser engraving

When the UV laser marking machine is in use, the problem of weak laser light and shallow laser engraving depth often occurs. This problem is generally caused by improper operation.

1. Check whether the laser of the UV laser marking machine deviates from the center point after entering the galvanometer. The optical path is biased, so that the beam cannot be concentrated in the corresponding marking area, so the marking pattern and text will become very shallow. At this time, you can use the frequency multiplier to adjust the optical path to restore the normal state.

2. Check whether the output current of the acousto-optical power supply is low or the position of the acousto-optical crystal is shifted, increase the current of the acousto-optical power supply or correct the position of the acousto-optical crystal, if the power supply current is too small, the beam is too small or the marking frequency appears abnormal, thus affecting the marking effect. Generally, the larger the current of the laser engraving machine, the higher the marking intensity will be.

3. Whether the resonant cavity of the UV laser marking machine has been used for a long time and the lens of the UV laser marking machine is too dirty, so that the emitted laser beam cannot be expanded and focused, which affects the marking effect and the position changes slightly. , and fine-tune each mirror of the resonator to optimize the spot. If the lens is too dirty, you can use a cotton swab dipped in alcohol for scrubbing. This cleaning method is effective and will not damage the parts of the laser engraving laser machine.

4. The speed of the UV laser marking machine is too fast, and the beam has not yet achieved the marking effect. If the marking speed exceeds the designed frequency range, it will affect the marking effect and make the text or pattern unclear.

5. UV 레이저 마킹기의 전류가 25A로 조정되면 레이저의 마킹 깊이가 충분히 강하지 않은 경우 크립톤 램프에 문제가 있으며 크립톤 램프를 교체해야 함을 의미합니다.

UV 레이저 마킹기 레이저 빔의 초점 심도는 파장에 반비례합니다. 대물렌즈의 후방주사모드에서 정적집속방식을 채택하면 초점면은 구형 호면이다. 전체 작업 표면의 디포커스 오차가 초점 심도 범위 내에서 제어되면 정적 포커싱 방법을 채택할 수 있습니다. 오류가 초점 심도 범위에서 너무 멀리 벗어나면 동적 초점 조정이 필요합니다.
