Description
Technical field
The present invention relates to a kind of laser process equipment, specifically a kind of glass enclosed type CO that is used on the laser engraving machine
2Laser.
Background technology
Glass enclosed type CO
2Laser is formed by the glass tube encapsulation, so be commonly called as laser tube.Laser tube can be used for carving or cutting on the laser engraving machine of nonmetallic materials such as rubber, plastics, textile.
The operation principle of laser tube is: electrion excites high concentration CO
2Gas produces the laser of wavelength 10.6um, and it mainly contains hard glass, resonant cavity, electrode three parts composition:
1, hard glass part: these parts are fired into discharge tube, water collar, gas storage cover and muffler by GG17 and form.Enclosed type CO
2Laser is generally three layers of sleeve structure.Innermost is discharge tube, and the centre is that water overlaps only, and outermost one deck is the gas storage cover, and muffler is to be used to be communicated with discharge tube and gas storage cover.
2, resonant cavity part: these parts are made up of total reflective mirror and output reflector.The total reflective mirror of resonant cavity generally is substrate with optical glass, the surface gold-plating film, and golden film speculum reaches more than 98% near the reflectivity the 10.6um; The germanium (Ge) that the output reflector of resonant cavity generally adopts transmissive 10.6um radiation is substrate, plates multilayer dielectric film in the above and makes.
3, electrode part: CO
2Laser generally adopts cold cathode, is shaped as cylindrical shape, and cathode material selects for use the life-span to laser to have a significant impact, and the basic demand of target material is: sputtering raste is low, and the bulk absorption rate is little.
The life-span of laser tube differs bigger at present, mainly is that factors such as designing technique cause owing to processing technology.The working life of general homemade laser tube is (60W is an example) about 1500 hours.The laser tube of different performance, largest light intensity there are differences, i.e. the laser energy difference.Optical quality is by laser tube pattern decision, the quality of hot spot, and by all too many levels decisions of production technology, the performance that the quality of hot spot directly has influence on the user when using.The stable difference of different laser tubes is also very big, the product of poor performance, and stable aspect is prone to gas leakage, and non-external cause such as bursts at problem.
The structure of existing laser tube is seen Fig. 1, and it mainly is in the hard glass body 11 of a sealing, fills out and is provided with carbonated mist, and the set electrode 12 at the laser tube two ends forms a resonant cavity and then produces laser.End at body 11 is provided with the laser head 13 that has eyeglass 14.Because laser head and the hard glass body that uses is linked to be an integral body at present, eyeglass is fixed in the laser head, and the material of laser head is the glass consistent with the hard glass body, producing laser simultaneously, horminess glass tube is known from experience the heating distortion, causes laser head heating distortion, causes laser head to damage and can not use, and then make and whole laser tube subscription rate increased cost.
Summary of the invention
In order to overcome the problem that prior art exists, the purpose of this invention is to provide a kind of glass enclosed type CO
2Laser, laser head and eyeglass in this laser are replaceable, durable in use, and long service life has been saved user's cost greatly; And power is big, penetration power is strong.
The objective of the invention is to be achieved through the following technical solutions:
A kind of glass enclosed type CO
2Laser is provided with the laser resonator of connection on body; End in laser resonator is provided with laser head, it is characterized in that: the described laser head that is made of metal comprises Connection Block and lens mounting stand, is provided with the endoporus suitable with body on Connection Block; Front end at lens mounting stand is provided with the eyeglass mounting groove, is provided with eyeglass in the eyeglass mounting groove; Connection Block is connected with lens mounting stand by screw thread, and is provided with the adjustment screw between Connection Block and lens mounting stand.
The present invention is provided with the lens protection cover at the lens mounting stand front end.The lens protection cover is used for the protective glass sheet and is not damaged.In order to prevent that electric discharge phenomena take place when producing laser, on lens mounting stand, be provided with discharge aperture.
Because laser tube is the easy consumption parts, existing glass laser pipe is generally as disposable use.And be made of metal owing to laser head among the present invention, be connected on the canals of stilling by glue, indeformable when canals of stilling adstante febre laser head, therefore can inflate use repeatedly.Eyeglass is installed in the eyeglass mounting groove by glue, when eyeglass can not meet the demands, as long as change eyeglass separately.Compared with prior art, laser head of the present invention and eyeglass are replaceable, and be durable in use, and long service life has been saved user's cost greatly; And power is big, penetration power is strong, cheap, economical and practical, has obtained domestic and international client's approval.
