Description
Technical field
The utility model relates to a kind of laser engraving machine optical transmission apparatus, especially relates to a kind of laser engraving machine optical transmission apparatus with thermal component.
Background technology
Current laser engraving machine is widely used in the engraving to the metals such as poly (methyl methacrylate) plate, plastic plate, cardboard, density board and glass surface mask (one glass spray sand processing) and nonmetal plate, and the laser engraving head of existing laser engraving machine has frame modes such as adopting single track single head, single track double end, dual-rail dual-head.
At present, the powerful optical transmission component of laser engraving machine, occurs that after working long hours the carved product degree of depth is uneven, due to present stage equipment by naturally cooling and part air-cooled, in engraving, have heat radiation energy imbalance, the strict product of quality requirement there will be does over again.
Utility model content
The purpose of this utility model be exactly provide a kind of to overcome defect that above-mentioned prior art exists and reduce maintenance cost, stabilized lasers scribe power, laser focal are stablized, the laser engraving machine optical transmission apparatus of band thermal component that improves the quality of products.
The purpose of this utility model can be achieved through the following technical solutions:
With a laser engraving machine optical transmission apparatus for thermal component, this device aims at roller to be carved, it is characterized in that, described optical transmission apparatus comprises:
Light path room;
Light-emitting window, arranges light path indoor;
Beam expanding lens, is arranged on light path indoor;
Thermal component, is arranged on light path indoor and encases beam expanding lens, for the heat radiation of beam expanding lens;
Focusing block, the port of export of the light path room be located at, and remain on same central point with light-emitting window, beam expanding lens.
Described thermal component comprises cooler bin and the air inlet arranged respectively on cooler bin and gas outlet;
Compressed air enters the air admission hole of cooler bin, from the venthole of cooler bin out, rapidly by the heat absorption of beam expanding lens.
Described focusing block comprises focusing lens, focus head and focuses into pore, and described focusing lens, focus head are located on same central point, and the described pore that focuses into is connected with the venthole of cooler bin; Enter again from the venthole compressed air out of cooler bin and focus into pore, focus head inside is made to form malleation on the one hand, effectively prevent space of a whole page glue ash to be adsorbed onto focusing lens, the heat on the other hand focusing lens being produced is taken away, and guarantees that laser focal is relatively stable.
Described light-emitting window, beam expanding lens, focusing lens and focus head remain on same central point.
Described light path room is the inner light path room forming malleation.
Compared with prior art, the utility model has the following advantages:
1, maintenance cost is reduced: beam expanding lens is for a long time by laser, and form amount of heat, the eyeglass life-span is short.
2, stabilized lasers scribe power: laser is easily by external environmental interference, and when optics temperature raises, laser power can large lossy, cause laser engraving power unstable, install beam expanding lens refrigerating plant additional, lowered the temperature by compressed air, make laser power be in poised state.
3, laser focal is stablized.
4, improve the quality of products.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein 1, light path room, 2, light-emitting window, 3, air admission hole, 4, beam expanding lens, 5, venthole, 6, focusing lens, 7, focus head, 8, focus into pore, 9, roller, 10, cooler bin.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
As shown in Figure 1, the laser engraving machine optical transmission apparatus of band thermal component, this device aims at roller 9 to be carved, and described optical transmission apparatus comprises: light path room 1; Light-emitting window 2, arranges in light path room 1; Beam expanding lens 4, is arranged in light path room 1; Thermal component, is arranged on light path indoor and encases beam expanding lens 4, for the heat radiation of beam expanding lens; Focusing block, the port of export of the light path room be located at, and remain on same central point with light-emitting window, beam expanding lens.
Described thermal component comprises cooler bin 10 and the air inlet 3 that arranges respectively on cooler bin and gas outlet 5; Focusing block comprises focusing lens 6, focus head 7 and focuses into pore 8.
Thermal component and laser part are combined closely, use the good material of thermal conductivity by laser part heat absorption, heat radiation material carry heat is walked by compressed air medium by thermal component inside, reach thermal equilibrium state fast, optics heat distortion amount is reduced to the scope not affecting carved product quality.
Operation principle:
Compressed air enters the air admission hole 3 of cooler bin, from the venthole 5 of cooler bin out, rapidly by the heat absorption of beam expanding lens 4 and cooler bin 10, enter again and focus into pore 8, focus head 7 inside is made to form malleation on the one hand, effectively prevent space of a whole page glue ash to be adsorbed onto focusing lens 6, the heat on the other hand focusing lens 6 being produced is taken away, and guarantees that laser focal is relatively stable.
Light-emitting window 2, beam expanding lens 4, focusing lens 6 and focus head 7 keep same central point; laser engraving product quality is improved, and light path room 1 forms malleation, prevents external dust from entering; the eyeglass of available protecting light-emitting window 2, beam expanding lens 4 and focusing lens 6, can not damage the short time.
Laser is emitted by light-emitting window 2, by beam expanding lens 4, is amplified by spot diameter, reduces the hot spot angle of divergence, finally by focusing sheet 6, laser facula is effectively focused on, forms high-quality hot spot, penetrate eventually through focus head 7, carve on roller 9 surface.
