Description
Technical Field

Background
Before the lamination operation of photovoltaic manufacture, a high-temperature adhesive tape is required to be arranged on the surface of a packaging material layer to prevent the adhesive from overflowing in the lamination process, a bus bar penetrates through the high-temperature adhesive tape from bottom to top, and the solar cell lamination parts are respectively attached to two outer sides in the lamination process, so that the high-temperature adhesive tape and the bus bar are tightly attached to the surface of the laminated solar cell lamination part.
However, during subsequent installation with the junction box, it is necessary to remove the high temperature adhesive tape from the surface of the solar cell laminate and rotate the bus bar to a position substantially perpendicular to the surface of the solar cell laminate.
In order to reduce labor cost, mechanical devices for automatically removing the high-temperature adhesive tape have been developed in the prior art, but the effect is not ideal, and the failure rate of removing the high-temperature adhesive tape is high, and the current design is to try to blow up the edge of the high-temperature adhesive tape by blowing air, then pre-shovel the high-temperature adhesive tape from the width direction of the bus bar, and finally clamp the edge of the high-temperature adhesive tape from the length direction of the bus bar by using a clamping head, but such a way (hereinafter referred to as a comparative example) is difficult to succeed in practice, and the comparative example has at least the following defects:
first, the high temperature tape is not as easily blown up as silk or light and thin cloth;
secondly, even if the high-temperature adhesive tape is blown up, the high-temperature adhesive tape is always in a fluctuating state and is difficult to be clamped by a clamping head;
more importantly, the bus bar is scooped up from the width direction thereof, so that a torsion force is generated between the bus bar portion led out from the laminate and the bus bar portion laminated therein, causing the bus bar to be deformed or even causing the bus bar to be broken, seriously affecting the product quality.

specifically, as shown in fig. 5 and 6, the suction port 210 of the suction mechanism 200 and the shovel mechanism 300 are arranged on the same base frame, the suction port 210 is higher than the shovel members 310 of the shovel mechanism 300, the number of the shovel members 310 is two and the shovel members 310 are arranged oppositely, and under the driving of the propelling driving assembly 320, the shovel members 310 move inwards along the length direction of the bus bar 720, that is, the shovel members 310 are shoveled from the two ends of the bus bar in the length direction to the middle; the shovel member 310 may also be provided with a resilient member (not shown) on its lower portion, such that the resilient member (e.g., a spring or a flexible layer) may provide a cushioning force to prevent the shovel member 310 from damaging the solar cell laminate should the pushing shovel mechanism 300 be moved down to contact the solar cell laminate with the shovel member 310.
Moving the components of fig. 5 horizontally above the high temperature adhesive tape 710, the suction mechanism 200 starts the suction pump, and the shovel 310 moves downward to a height position lower than the sucked high temperature adhesive tape (not to stick to the solar cell laminate as much as possible), and then the pushing driving assembly 320 operates to cause at least the edge region of the bus bar 720 and the edge region of the high temperature adhesive tape to be scooped up by the shovel 310 based on the effect of slightly tilting the free end of the bus bar 720 brought by the first step.
Thirdly, clamping the edge of the scooped high-temperature adhesive tape by using a clamping jaw, and moving the clamping jaw to drive the high-temperature adhesive tape to be separated from the solar cell laminating piece;
specifically, as shown in fig. 7 and 8, the gripping parts of the gripping mechanisms 400 are two in number and are arranged oppositely, the upper surface of the lower claw 420 of each gripping mechanism 400 is inclined downward in the inward direction, the lower surface of the upper claw 410 is inclined downward in the inward direction, and the upper claw 410 has an avoiding structure (i.e., an inverted U-shaped structure) for avoiding the bus bar; it is noted that the distal end of the lower jaw 420 in the separated state protrudes inward with respect to the distal end of the upper jaw 410, which enables the lower jaw 420 to more easily enter the lower region of the high temperature tape 710 without interference from the upper jaw 410, and prevents the upper jaw 410 from entering the lower region of the high temperature tape 710 together;
as shown in fig. 7, the clamping driving assembly includes a first clamping driving member 430 and a second clamping driving member 440, wherein the first clamping driving member 430 is configured to drive the lower jaw 420 to move inward to a preset clamping position along the length direction of the bus bar 720, the second clamping driving member 440 is configured to drive the lower jaw 420 to move upward and outward through a link 450 until the lower jaw 420 is closed with the upper jaw 410, and the end of the lower jaw 420 in the closed state is flush with the end of the upper jaw 410 or spaced less than 6mm apart. In one embodiment, the lower surface of the upper jaw 410 of the grasping mechanism 400 is provided with an anti-slip structure 412 (such as a rubber layer or a serrated structure as shown in fig. 8).
Moving the part of fig. 7 horizontally to the upper side of the high temperature adhesive tape 710 (the two clamping parts are respectively at the left and right sides of the high temperature adhesive tape along the length direction of the bus bar), moving the clamping mechanism 400 downwards until the lower claw 420 is lower than the edge of the high temperature adhesive tape which is scooped up, and then the first clamping driving member 430 acts to make the lower claw 420 extend into the lower side of the high temperature adhesive tape 710; then the second clamping driving member 440 acts to close the upper jaw 410 and the lower jaw 420 to clamp the edge of the high temperature adhesive tape; finally, the clamping mechanism 400 is moved upwards to drive the high temperature adhesive tape 710 to separate from the solar cell laminate.
In a specific embodiment, the gripping mechanism 400 is further provided with a sensor 460 configured to detect the gripping condition of the high temperature adhesive tape by the lower jaw 420 and the upper jaw 410 in the closed state;
if the sensor 460 detects that the lower jaw 420 and the upper jaw 410 in the closed state do not clamp the high temperature adhesive tape, the gripping mechanism 400 performs the gripping operation again, or the post-lamination processing apparatus performs the post-processing operation again (for example, from the first step or from the second step);
it is also possible to detect whether the high temperature adhesive tape 710 is separated from the solar cell laminate after the third step is performed by using the sensor 460, and if it is still attached to the surface of the solar cell laminate, the gripping mechanism 400 performs the gripping action again, or the post-processing operation is performed again by the post-lamination processing apparatus.
If the number of times of continuous clamping failures of the clamping mechanism 400 exceeds a preset number threshold, the post-lamination treatment equipment stops operating and/or triggers a prompting device to send out an alarm signal.
The sensor 460 is arranged to detect whether the high temperature adhesive tape 710 is smoothly clamped or separated from the solar cell laminate, which is of great significance to the actual processing, because there may be mechanical error, or the high temperature adhesive tape 710 is too small in size, or various factors such as the engaging force between the upper claw 410 and the lower claw 420 of the clamping portion is weakened, which may cause the high temperature adhesive tape 71 to fail to separate from the solar cell laminate after the third step, in which case if the third step is performed further downwards, the bus bar and the solar cell laminate may be damaged, resulting in defects of the product.
Fourth, the step of shaping the bus bar by the shaping mechanism 500 continues to refer to fig. 12: placing a reference block in the middle area of the bus bar, wherein the reference block is provided with a middle section which is matched with the width of the bus bar and is in a concave structure;
as shown in fig. 9, the reshaping mechanism 500 includes a reference block 510, a deviation rectifying driver 550, a bending driving assembly 530 and bending operation members 520 disposed at two sides of the reference block 510, as shown in fig. 10, a middle section 512 of the reference block 510 is recessed with respect to the two sides, and the width of the middle section 512 can be adjusted to match the width of the bus bar 720 under the driving of the deviation rectifying driver 550. In a specific embodiment, the reference block 510 comprises a first block 514 and a second block 516 which are interdigitated, and the reshaping mechanism 500 further comprises a limiting post 540 for limiting the minimum distance between the first block 514 and the second block 516, as shown in fig. 10, wherein 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 720 with different widths can be adapted.
The deviation rectifying driver 550 is configured to cooperate with the Z-axis driving assembly, after the bottom surface of the reference block 510 contacts or is adjacent to the middle area of the bus bar 720, the deviation rectifying driver 550 adjusts the width of the middle section 512 to be smaller (fig. 10 is the state before the deviation rectifying driver 550 acts), that is, the deviation rectifying driver 550 drives the first block 514 and the second block 516 to move towards each other until the extending end of the position-limiting post 540 abuts against the first block 514, it can be understood that one solution is to align the center of the reference block 510 with the bus bar 720, that is, the first block 514 and the second block 516 are symmetrically arranged on both sides of the bus bar, and the distance of the movement of the two blocks towards each other is equal, since the extending distance of the position-limiting post 540 is approximately equal to the width of the bus bar 720, when the extending end of the position-limiting post 540 abuts against the first block 514, at least the lower portion of the bus bar 720 is clamped in a channel with the same width as the channel, and the channel is consistent with the length direction of the bus bar 720, that is finished (the deviation rectifying bus bar is offset in the width direction of the bus bar is 0 even if the deviation rectifying process occurs in the width direction in the process of removing the high temperature adhesive tape 710).
As shown in fig. 11, an operation end 522 is provided on a side surface of the bending operation member 520 opposite to the reference block 510, and a width of the operation end 522 is smaller than a width of the bus bar 720; the bending driving assembly 530 is configured to cooperate with the Z-axis driving assembly, and after the bus bar 720 is corrected, the bending driving assembly 530 drives the bending operation members 520 on two sides to move towards each other until the operation end 522 abuts the lower end of the bus bar 720 on the vertical surface of the middle section 512 in the recessed structure; the operating end 522 is moved upward (the bending operation member 520 is moved upward) so that the operating end 522 performs a straightening operation on the bus bar 720 along the vertical surface of the middle section.
In the embodiment, the post-processing apparatus further includes a visual positioning device, which includes a processor and a camera for collecting image information of the solar cell laminate to be processed, and the processor is configured to calculate the current position of the gluing mechanism 100, the pushing shovel mechanism 300, and the clamping mechanism 400 and the relative position information of the high temperature adhesive tape 710 or the bus bar 720 on the solar cell laminate according to the image information collected by the camera. The present invention is not limited to this visual positioning scheme, and for example, the positional information of the high temperature adhesive tape 710/bus bar 720 on the solar cell laminate of the specification can be entered into the system in advance.
Comparative example
Comparative example and the protocol of the present application were performed separately on solar cell laminates of the same specifications, with the parameter pairs of the embodiments as shown in table 1:
TABLE 1
As can be seen from the comparative data in table 1, the clamping success rate in the comparative example is 91%, even if 12 times of clamping succeeds, the high-temperature adhesive tape cannot be successfully separated from the surface of the laminate, the high-temperature adhesive tape tearing success rate is only 79%, and the product breakage rate is 2%;
in the application, the high-temperature adhesive tape and the surface of the laminating piece are loosened by using an adhesive method, so that the high-temperature adhesive tape can be stably torn off after subsequent successful clamping; the pre-shoveling mode is adopted along the length direction of the bus bar, so that the bus bar cannot be broken due to torsion even if the stroke of the pre-shoveling is longer; the sufficient pre-shoveling stroke can enable the edge of the high-temperature adhesive tape to be clamped successfully in subsequent operation more easily, and can also enable the shoveled height of the free end of the bus bar to be increased, so that the resistance in the subsequent process of tearing off the high-temperature adhesive tape is reduced, and the success rate of the high-temperature adhesive tape to be separated from the surface of the laminated piece is further improved.
