Laser head, fiber section very easily damage, and reasons such as the main cause of damage is too high owing to temperature, input current overtension, input current sudden change cause, and the cooling of these parts is to rely on water-cooling system to finish.Therefore; aspect laser controlling, should accomplish anhydrous not switch power supply; the slow step change of Control current, and the carrying out of the temperature of these parts, water system operating state, source current, voltage monitored the damage that these parts just can be finely avoided in the fast processing protection in real time.Simultaneously, water system leaks and also can damage laser head, power supply and main controller, the detection of the aspect of also should accomplishing to leak.For the eyeglass part, the steam dewfall is to life, and bright dipping at this moment will cause eyeglass to damage.Therefore feeding high pure nitrogen drives away the steam in the optical cavity.Simultaneously, the temperature of eyeglass cooling water is crossed low easy dewfall, and the too high eyeglass that also can cause of temperature bursts, and therefore also should carry out turn-on temperature detection and corresponding techniques and item security and detect.The function that the present invention possesses just is based on the such scheme design.
All solid laser control system of the present invention startup-shutdown one-key operation simple to operation, start back system program brings into operation, continuous mutually automatically unlatching relevant device, and the running status of detection relevant device, thus the control complete machine carries out operate as normal.
By the start key, automatically open the protection air cock subsequently, whether and to detect protection gas normal, if normal, the high purity nitrogen protection of preliminary filling gas is in case the eyeglass dewfall in two fens clock times; Then open the water-cooled mechanism of laser head cooling water, and whether detect the water route normal; And then detect turn-on temperature whether in prescribed limit, and control makes cooling water meet the requirements of temperature automatically, after touring comprehensively detection is normal, automatically open laser powered sensor mechanism, automatically regulate current preheating one minute, the power that automatic subsequently bring to power is extremely set, but at this moment with regard to operate as normal.Still move by same start-stop switch program during shutdown, when making electric current slowly drop to zero automatically, outage is closed water-cooled mechanism after the time-delay several seconds automatically automatically.
The present invention partly accomplishes anhydrous not switch power supply in laser controlling; Control current slowly the step change, and to the automatic interlock safeguard protection of the real-time monitoring of temperature, cooling water operating state, source current, the voltage of associated components, multi-parameter such as leak, fast processing, implementation system, avoid damaging associated components and drainage takes place and damage palladium bar, power supply and control circuit.
The present invention compares with used conventional laser and possesses following advantage:
1, power given smooth operation
Power of the present invention adopts direct given power when adjusting, the method that the inner laser head source current of regulating certainly reaches given power is carried out the power adjustment.
2, ancillary equipment communication interlock
Equipment of the present invention moves input equipment and actuator (robot) interface automatically, can carry out the man-machine communication, in actuator (robot) but the also power lifting of feedback signal control full-solid state high power laser control system of actuator in the switch operation, the optical gate switch, pilot light switch etc., when actuator breaks down, feed back to full-solid state high power laser system alarm information, make the full-solid state high power laser system close power and optical gate automatically.
3, misoperation and prompting
Complete machine is followed a cover safe operation program and rules, when ignorant other buttons of pressing, and breach of security working procedure, it is invalid to operate, and display reminding misoperation and proper operation method.
4, relevant protection is perfect
The present invention is to the laser head, and eyeglass etc. carry out careful protection comprehensively, do not make temperature too high, temperature jump, and in the useful life of having improved complete machine, the present invention has efficiently, energy-saving and environmental protection, safe and reliable characteristics.Design science of the present invention, reasonable, original, stable performance, reliable has extremely strong practicality and advance, and is easy for installation, simple to operate, operation cost is low, and suitable laser equipment manufacturing and laser processing industry are used.
