The common faults and measures of laser marking machine:
The new device 1 using time is not long, the reason of laser output power weak:
The factory test of laser output power was whether the technical index;
Whether the resonant cavity adjustment accuracy to meet the requirements;
The whole film is light leakage;
The acousto-optic switch insertion loss in the specified range.
After 2 laser marking machine is used for a period of time, the reason of laser laser output power drop:
The laser cavity resonator mirror: whether changes of fine-tuning, so that the output spot of the best;
The anti - and output membrane fouling phenomenon is there;
The acousto-optic crystal offset or acousto optical power output energy is low: adjust the position of acoustooptic crystal;
If the cooling water tank temperature setting and environment temperature more than 5 DEG c.;
The krypton lamp life is out of date;
Enter into the Laser Galvanometer off center: adjusting the laser;
And if the current to about 20A still photographic strong enough: krypton lamp aging, the replacement of the new lamp.
3 laser marking machine, laser output power is normal, but the laser beam can not play the role of marking:
The optical system adjustment is accurate;
Whether the acousto-optic switch can play a role switch;
The D/A card control acousto optical output signal is up to 5V.
Reason 4 laser marking machine acoustooptic switch can not play the role of Q-switched laser:
The acousto optical power RF output power is normal;
The power supply of each switch is in correct position;
The RF line connection is reliable;
The Q switch light face with no fouling phenomenon.
