Laser makes mark machine common breakdown and its means of settlement
Breakdown 1: Laser intensity drops, sign is not quite clear
Means of settlement:
Whether does antrum of ① laser resonance change; Lens of antrum of fine tuning resonance. Make output facula best;
② is acousto-optic crystal deflection is acousto-optic perhaps power source outputs energy on the low side; Adjust acousto-optic crystal position perhaps increases electric current of work of acoustical photoelectricity source;
③ enters laser deviate center of Zhen Jing: Adjust laser;
④ if electric current moves 20A left and right sides to still feel light intensity is insufficient: Krypton lamp ageing, change new light.
Breakdown 2: Krypton lamp cannot spark (referenced NTP power source uses manual)
Means of settlement:
① checks all power source jumper;
Ageing of lamp of krypton of ② high pressure, change krypton lamp.
Operation laser makes mark machine note
① forbidden anhydrous or boiler circulation start laser power source and tone Q power source below abnormal condition;
② does not allow sky of Q power source to hold the job (move Q power source to output end namely impending) ;
③ appears unusual appearance, shut Zhenjing switch and key switch above all, check all right again;
④ does not allow to start other component before krypton lamp is ignited, in case high-pressured change enters attaint component;
⑤ notices laser power source outputs end (zincous) impending, in case with strike a light of other electric equipment, puncture;
⑥ maintains inside circular water is clean. Clean cistern regularly and change clean go ionic water or pure water.
The use of krypton lamp and change
Shut water-cooling engine, stimulate photoelectricity source.
Open upside 3 antrum lid, take out the lamp that should change or crystal, after changing, put, mount antrum is built.
Fly water-cooling plane, stimulate photoelectricity source, laser source current tone arrives (15~20) A left and right sides. 1 jackstraw or black paper are placed between advanced diaphragm and enlarge Shu Jingzhi, should see the facula that laser ablation forms. If do not have, 3 knob of horse of the film before light fine tuning is whole, appear till facula.
Laser is debugged after coming out, 3 knob of horse of the film before answering to be adjusted repeatedly make facula the strongest, if laser crosses strong, brightness exorbitant when cannot observing, can reduce source current.
Shut laser power source.
Special attention: Change the time of krypton lamp.
Lamp of the krypton in laser leaves factory the service life that shows krypton tube is 300 hours, but differ as a result of user use condition, afore-mentioned time can not serve as change the only basis of krypton lamp. As the addition of use time, the glow efficiency of krypton lamp drops, laser is outputted also subsequently abate, a lot of users are outputted to obtain enough laser, increase the electric current of laser power source, make krypton lamp glow increases, this makes krypton lamp ageing is accelerated, form vicious circle, can cause scamper lamp appearance sometimes. To prevent this kind of phenomenon happening, our proposal user decides to whether should change by the method below krypton lamp.
