Evenly sized focused spot is formed on 17,17 the smooth of the edge of workpiece to be processed that cuts or carve, precisely.
The present invention makees reference using visible ray, to solve at present due to the reference without standard point during adjusting, in school
It is needed blindly during positive laser optical path and repeatedly adjusts reflective mirror, so as to which light path be caused to be difficult to correct what can not even be corrected
Problem；It solves in correction course simultaneously, due to CO2Laser power is excessively high, when laser optical path deviates excessive, laser optical path deviation
Go out reflective mirror, damage people or the problem of damage object during fixed fire.
Although to be adjusted moreover, there are also enterprises or individual at present using auxiliary device, these auxiliary devices are all
Manual adjusting ball head plunger is needed, adjusting process is comparatively still cumbersome, and error is larger.Present invention introduces motor,
The automatic regulating system that motor driver, motor control module, central processing unit, locating module and sensor form, is abandoned
The triviality of manual constantly regulate bulb plunger so that adjust intelligent process, simplification, precision；Laser is converted simultaneously
Into visible ray, the safety of operation is improved and reliability that reference point compares.
It should be understood that for those of ordinary skills, can be improved or converted according to the above description,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
