Summary of the invention
Technical problem to be solved by this invention is, provides a kind of thin-film solar cells busbar that can improve mechanization degree that busbar lays moulding, production efficiency height, stable processing quality to lay shaped device.
The inventive system comprises a hold-down support, a slide that can move horizontally before and after the horizontal guide rail is installed on the hold-down support, be equipped with on the slide the preceding pinch roller that can together move forward and backward with slide, back pinch roller, in carry wheel, put belt wheel, feed mechanism and cutting mechanism; Before pinch roller, in carry the wheel and the back pinch roller be sequentially arranged in from front to back on the moving direction of slide; Pinch roller before described, back pinch roller and in carry wheel respectively can be under vertical driving air cylinder driven separately vertical lifting, in carry wheel and also can under the driving of horizontal drive cylinder, move horizontally with direction perpendicular to above-mentioned horizontal guide rail, between pinch roller before entering or withdrawing from and back pinch roller; Feed mechanism is arranged on the rear of back pinch roller, and feed mechanism is provided with fixture, and fixture can clamp or unclamp one section aluminium strip, and fixture can move forward and backward under the driving of sending cylinder to; The aluminium strip of whole volume is placed in to be put on the belt wheel and can send aluminium strip along with the rotation of moving and putting belt wheel of feed mechanism; Cutting mechanism can enter or withdraw from the rear of back pinch roller under the driving of a scissors driving cylinder; Vertically the moving of the moving forward and backward of described slide, preceding pinch roller and back pinch roller, in carry wheel vertically and move horizontally, feed mechanism move forward and backward and the clamping of fixture or unclamp the advance and retreat of action, cutting mechanism and shear action by the control system centralized control.
Carry wheel during the horizontal drive cylinder of carrying wheel in described directly drives and move horizontally, in carry wheel vertical driving cylinder carry the vertical lifting of wheel in driving by the mount pad of carrying the horizontal drive cylinder of wheel in driving.
The present invention can finish the laid processes of thin-film solar cells busbar automatically, its reliable in action, production efficiency height, steady quality.
Embodiment
As shown in Figure 1, the inventive system comprises a hold-down support 1, a slide 2 that can move horizontally before and after the horizontal guide rail is installed on the hold-down support, be equipped with on the slide the preceding pinch roller 3 that can together move forward and backward with slide, back pinch roller 4, in carry wheel 5, put belt wheel 6, feed mechanism 7 and cutting mechanism 8; Before pinch roller 3, in carry the wheel 5 and the back pinch roller 4 be sequentially arranged in from front to back on the moving direction of slide 2; Before pinch roller 3, back pinch roller 4 and in carry wheel 5 respectively can be under vertical driving air cylinder driven separately vertical lifting, in carry wheel and 5 also can under the driving of its horizontal drive cylinder, move horizontally with direction perpendicular to above-mentioned horizontal guide rail, with between pinch roller before entering or withdrawing from and the back pinch roller (referring to Fig. 2); Feed mechanism 7 is arranged on the rear of back pinch roller 4, and feed mechanism is provided with fixture 9, and fixture can clamp or unclamp one section aluminium strip A, and fixture can move forward and backward under the driving of sending cylinder 10 to; The aluminium strip A of whole volume is placed in to be put on the belt wheel 6 and can send aluminium strip along with the rotation of moving and putting belt wheel 6 of feed mechanism 7; Cutting mechanism 8 can enter or withdraw from the rear (referring to Fig. 3) of back pinch roller 4 under the driving of a scissors driving cylinder 12; Vertically the moving of the moving forward and backward of described slide 2, preceding pinch roller 3 and back pinch roller 4, in carry wheel 5 vertically and move horizontally, feed mechanism 7 move forward and backward and the clamping of fixture 9 or unclamp the advance and retreat of action, cutting mechanism 8 and shear action by the control system centralized control.
As shown in Figure 2, carry wheel 5 during the horizontal drive cylinder 13 of carrying wheel in described directly drives and move horizontally, in carry wheel vertical driving cylinder 14 carry the vertical lifting of wheel 5 in driving by the mount pad of carrying the horizontal drive cylinder of wheel in driving.
Shown in Fig. 4 a-Fig. 4 f, it is as follows that device of the present invention carries out the process that busbar lays:
The first step, shown in Fig. 4 a, the glass substrate B that end face had pasted the thin-film solar cells of adhesive tape be placed in preceding pinch roller, in carry wheel and pinch roller below, back, feed mechanism 7 is sent aluminium strip A end forward to, and to preceding pinch roller 3 belows, preceding pinch roller 3 moves down, aluminium strip A end is overlayed adhesive tape front end on glass substrate, slide 2 moves backward then, and pinch roller rolls backward before driving, and one section aluminium strip is pulled out and overlayed on adhesive tape;
In second step, shown in Fig. 4 b, slide 2 stops after moving to the precalculated position, and the wheel 5 of carrying at pinch roller 3 rears upwards is promoted to setting height before being arranged in, and one section aluminium strip is upwards turned up;
The 3rd step, shown in Fig. 4 c, in carry wheel 5 and promote to finish back feed mechanisms 7 and retreat, back pinch roller 4 descends, and aluminium strip is also overlayed on adhesive tape once more to bending;
The 4th step, shown in Fig. 4 d, in carry that wheel 5 descends and withdraw between pinch roller 3 and the back pinch roller 4 in the past, simultaneously before pinch roller 3 rise, so far finish the moulding of folded part in the middle part of the busbar;
In the 5th step, shown in Fig. 4 e, after the folded part moulding, slide 2 drives back pinch rollers 4 to be continued to be rolled into specific length backward, utilizes cutting mechanism 8 that aluminium strip is cut off, and back pinch roller continuation is rolled one section backward, with the aluminium strip compacting after cutting off;
The 6th step, shown in Fig. 4 f, back pinch roller lifting, all action is finished.
