the longer the bus bar of the first and exposed photovoltaic laminates is, the lower the tearing success rate of the high Wen Jiaobu is, because the travel of the pre-shovel is limited, the longer the bus bar is, the larger the area of the high-temperature adhesive tape still attached to the laminate is, and the resistance caused by the bus bar is overcome, so that the higher the clamping degree requirement on the clamping head is;
Secondly, in the process of tearing off the high-temperature adhesive tape by the clamping head, the bus bar is possibly distorted or even broken due to the fact that the clamping position deviates from the bus bar, and the product quality is seriously affected.

Referring to fig. 2 and 3, the pick up module 100, the progressive pick up module 200, the straightening module 500 and the recovery module 400 are integrated into a single structure 10 by mounting plates, the high temperature adhesive tape tearing device further includes a first lateral driving mechanism 610 and a second lateral driving mechanism 620 (see fig. 1) for driving the single structure 10 to move in a plane, so that the several modules can move horizontally in synchronization, and fig. 1 also shows a conveying device 650 for conveying the photovoltaic laminate 360, for conveying the photovoltaic laminate to be torn off of the high temperature adhesive tape 310 to a working platform where the first lateral driving mechanism 610 and the second lateral driving mechanism 620 are located, and transferring the photovoltaic laminate 360 to the next working platform after completing the current operation. The present invention is not limited to the arrangement order of the pick-up module 100, the progressive pick-up module 200, the straightening module 500 and the recovery module 400 as shown in fig. 2, but is not limited to the in-line arrangement form thereof, so long as the pick-up module 100, the progressive pick-up module 200, the straightening module 500 and the recovery module 400 can be respectively arranged up and down opposite to the high temperature adhesive tape 310/the bus bar 320 in sequence.

One photovoltaic laminate 360 as shown in fig. 1 has three bus bars, corresponding to three elevations Wen Jiaobu to be torn off, and corresponding to three elevations Wen Jiaobu tearing devices that can be mounted on the second lateral drive mechanism 620, the other two tearing devices being omitted from fig. 1. A second recovery container 380 for recovering the height Wen Jiaobu torn off from the photovoltaic laminate is provided at one end of the assembly, the number and specific positions of which are not limited.
The following describes the specific structure of each module one by one:
the structure of the picking up module 100 is shown in fig. 4 and 5, and includes a heating mechanism 110 configured with a heating head 112, two groups of clamping mechanisms 120 arranged at intervals, a first telescopic mechanism 130 for driving clamping jaws 122 of the clamping mechanisms 120 to telescopic, and a third lifting mechanism 150 for driving the clamping mechanisms 120 to lift; the pick up module 100 is configured to be moved to a standby container 330 (see fig. 2, which may be mounted at the other end of the assembly) and the first telescopic mechanism 130 acts to cause the jaws 122 of the two sets of clamping mechanisms 120 to each clamp an adhesive head 340 within the standby container 330; moving to a height Wen Jiaobu to be torn off 310, conveying heat to the high-temperature adhesive tape 310 by using the heating head 112, and loosening two ends of the high-temperature adhesive tape 310 relative to the photovoltaic laminate by using the adhesive head 340;
The pick up module 100 further includes a second pushing mechanism 140, the second pushing mechanism 140 being configured to drive the heating tip 112 into an area between two sets of clamping mechanisms 120. So that the clamping mechanisms 120 can be directly moved to the positions of the two groups of clamping mechanisms 120 which are respectively opposite to the two ends of the length of the high-temperature adhesive tape 310 up and down after the adhesive heads 340 are loaded, and then the heating head 112 is pushed to the upper part of the middle part of the high Wen Jiaobu by the second pushing mechanism 140, so that the number of times that the whole integral structure 10 needs to be moved is reduced.
That is, after the adhesive head 340 is clamped from the standby container 330 by the clamping jaw 122 of the picking up module 100, and then the thermal melting operation is performed on the height Wen Jiaobu 310 to be torn off by the heating head 112, the bus bar 320 is pressed above the height Wen Jiaobu 310 as shown in fig. 4, the two ends of the length of the high-temperature adhesive tape 310 are pressed down by the adhesive head 340, and then the adhesive head 340 is lifted up to loosen the two ends of the high-temperature adhesive tape 310 relative to the photovoltaic laminate 360, and the outer ends of the bus bar are slightly loosened.
With continued reference to fig. 6, the progressive scooping module 200 includes a pressing block 210, and scooping members 220 disposed on two sides of the pressing block 210, and further includes a second telescopic mechanism 230 for driving the scooping members 220 on two sides to move relatively, a first lifting mechanism 240 for driving the scooping members 220 to lift, and a second lifting mechanism 250 for driving the pressing block 210 to lift; the pressing block 210 is configured to press down or hang in the middle area of the two bus bars 320 at the high-temperature adhesive tape 310, the spade 220 is configured to descend to a position lower than the loose two ends of the high-temperature adhesive tape 310, and the actions of moving upwards after relatively approaching (moving towards each other along the length direction of the bus bars) are repeatedly performed, so that the high-temperature adhesive tape 310 is loose relative to the photovoltaic laminated piece in a stepwise manner, and the paths of the spade 220 at the two sides are shown in fig. 14; alternatively, the spade 220 is caused to perform a relatively close-side up-side motion to throw up the curve to loosen the high temperature tape 310 relative to the photovoltaic laminate 360.
Lifting up the spade 220 may prevent it from damaging the surface of the photovoltaic laminate 360 and may allow the curvature of the bus bar where it is currently spaded to change, reducing friction between it and the spade 220. The press block 210 is blocked in the middle during the process of the shovel 220 shoveling the height Wen Jiaobu, so that the two welding ends of the bus bar 320 are prevented from being excessively bent when the height Wen Jiaobu is peeled off, and the subsequent straightening operation is not facilitated.
Referring to the straightening module 500 of fig. 7, it is configured to perform a straightening operation on the bus bar 320 so as to convert the horizontal state of the bus bar 320 presented in fig. 4 into a vertical state; specifically, the alignment module 500 includes a reference block 510, a fifth lifting mechanism 560, a deviation rectifying driver 550, a bending driving assembly 530, and bending operation members 520 disposed on two sides of the reference block 510, where the middle section 512 of the reference block 510 has a concave structure with respect to two sides, and the width of the middle section 512 is adjustable to match the width of the bus bar 320 under the driving of the deviation rectifying driver 550.
In a specific embodiment, the reference block 510 includes a first block 514 and a second block 516 that are in an interdigital fit, the alignment module 500 further includes a limiting post 540 for limiting the minimum distance between the first block 514 and the second block 516, and the limiting post 540 is disposed on the second block 516 and extends toward the first block 514, and the extending distance can be adjusted by screwing, so that bus bars 320 with different widths can be adapted. After the bottom surface of the reference block 510 contacts or approaches the middle region of the bus bar 320, the deskew driver 550 adjusts the width of the middle section 512 to be smaller until it is adapted to the width of the bus bar 320.
