Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of photovoltaic cell stacking, and particularly relates to a stacking tool for photovoltaic cell manufacturing. BACKGROUND

[0002] In the production and manufacturing process of photovoltaic cells, multiple photovoltaic cells need to be stacked and stored or transported to the next process.

[0003] In related technologies, the stacking tool usually adopts a fixed fence structure, which has the following significant defects. When the photovoltaic cells fall, they directly impact the hard fence of the tool, which can easily cause edge and corner cracking or hidden cracking, especially for thin photovoltaic cells, which have a higher damage rate. Although some solutions add an elastic cushion layer, the buffer setting of the elastic cushion layer requires deformation space, which is contrary to the need for the stacking tool to clamp multiple photovoltaic cells. Therefore, the falling speed and distance of the photovoltaic cells can only be reduced, which requires additional movement of the external mechanical claw, thereby reducing the stacking efficiency.

[0004] Therefore, how to meet the photovoltaic cell falling buffer while not affecting the clamping requirement of the stacking tool is a technical problem to be solved.

[0005] It should be noted that the above information disclosed in this background section is only used to understand the background technology of the present application, and therefore, the above description is not considered to constitute prior art information. SUMMARY

[0061] It is found through research that the stacking tool usually adopts a fixed fence structure, which has the following significant defects: when the photovoltaic cell falls, it directly hits the hard fence of the tool, which is easy to cause edge and corner cracking or hidden cracking, especially for thin cell, the damage rate is higher. Although some schemes add elastic cushion layer, the buffer setting of the elastic cushion layer needs deformation space, which is contrary to the need of the stacking tool to clamp multiple photovoltaic cells, and cannot meet the use requirement of the photovoltaic cell.

[0062] Based on the above research, the embodiment of the present disclosure provides a stacking tool for photovoltaic cell pieces and a working method thereof. The buffer clamping piece arranged on the clamping plate actively absorbs the impact force during the falling of the photovoltaic cell pieces, avoids the direct collision between the cell pieces and the hard clamping plate, significantly reduces the risk of corner cracking and hidden cracking of the photovoltaic cell pieces, and after the stacking is completed, the position of the clamping plate is adjusted by external force, so that the buffer clamping piece is switched from the buffer state to the clamping state. After the buffer clamping piece is extruded and deformed, it is tightly attached to the side surface of the photovoltaic cell piece, providing uniform clamping force, overcoming the clamping looseness problem caused by the reserved deformation space of the traditional elastic pad layer, and ensuring the overall stability of the stack.

[0063] The defects of the above-mentioned solutions are the results of the inventors after practice and careful research, therefore, the discovery process of the above-mentioned problems and the solutions proposed by the present disclosure to solve the above-mentioned problems should be the contributions of the inventors to the present disclosure in the process of the present disclosure.

[0064] It should be noted that similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0065] Some embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the embodiments described below and the features in the embodiments can be combined with each other.

[0066] Please refer to Figure 1 and Figure 2 At least one embodiment provides a stacking tool for photovoltaic cell pieces, comprising: a bearing bottom plate 100; a plurality of clamping plates 200, one end of which is arranged around the bearing bottom plate 100, and the other end extends upward along the vertical direction; and a plurality of clamping plates 200 are arranged to form a stacking space for stacking photovoltaic cell pieces 400; wherein the clamping surface 210 of the clamping plate 200 is provided with a buffer clamping piece 300; when discharging, the falling of the photovoltaic cell pieces 400 is buffered by the buffer clamping piece 300; the two sides of the clamping plate 200 are provided with guide pieces, which make the clamping plate 200 drive the buffer clamping piece 300 to slide inward along the guide piece to clamp the stacked photovoltaic cell pieces 400 after the stacking is completed.

[0067] By setting the buffer clamping piece 300 on the clamping plate 200, the impact force is actively absorbed during the falling of the photovoltaic cell 400, avoiding direct collision between the photovoltaic cell 400 and the hard clamping plate 200, significantly reducing the risk of corner cracking and hidden cracking of the photovoltaic cell 400, and after the stacking is completed, the position of the clamping plate 200 is adjusted by external force, so that the buffer clamping piece 300 is switched from the buffer state to the clamping state, and after the buffer clamping piece 300 is extruded and deformed, it is tightly attached to the side of the photovoltaic cell 400, providing uniform clamping force, overcoming the clamping loose problem caused by the reserved deformation space of the traditional elastic pad layer, and ensuring the overall stability of the stack.

[0068] Please continue to refer to Figure 1 and Figure 2 , the guide piece includes a notch 110 opened at the matching position of the bearing bottom plate 100 and the corresponding clamping plate 200; the clamping plate 200 is slidingly arranged in the corresponding notch 110; wherein both sides of the notch 110 are provided with sliding holes 120; the bottom of the clamping plate 200 is connected to the bearing bottom plate 100 through the cooperation of the sliding bolt rod 130 and the sliding hole 120.

[0069] Through the cooperation of the sliding bolt rod 130 and the sliding hole 120, the clamping plate 200 can slide in the notch 110 and be fixed by the sliding bolt rod 130, which facilitates the alignment of the side wall of the photovoltaic cell 400 and the clamping of the photovoltaic cell plate.

[0070] Please continue to refer to Figure 1 and Figure 2 , one end of the notch 110 away from the clamping plate 200 is provided with a trigger adjusting piece 140; both ends of the trigger adjusting piece 140 pass into the corresponding sliding hole 120 from the notch 110, and both ends of the trigger adjusting piece 140 are provided with adjusting plates 141; during discharging, both ends of the trigger adjusting piece 140 are in an extended state to push the adjusting plates 141 at both ends against the side wall of the sliding bolt rod 130 to limit the sliding bolt rod 130; after the stacking is completed, both ends of the trigger adjusting piece 140 are pushed by external force to be in a retracted state to drive the adjusting plates 141 at both ends to separate from the side wall of the sliding bolt rod 130, facilitating the adjustment of the position of the clamping plate 200.

[0071] During the discharging stage, the adjusting plate 141 abuts against the sliding bolt rod 130, so that during discharging, the sliding bolt rod 130 does not need to be tightened, so as to facilitate the subsequent movement of the clamping plate 200.

[0072] It should be noted that the trigger adjusting piece 140 is only schematically shown on part of the clamping plates in Figure 1 and Figure 2 , and in actual use, the trigger adjusting piece 140 is arranged at each clamping plate.

[0073] Please refer to Figure 2 , the trigger adjustment piece 140 further comprises: a first connecting rod 142, a first articulated rod 143, a second articulated rod 144 and a second connecting rod 145; the first connecting rod 142, the first articulated rod 143, the second articulated rod 144 and the second connecting rod 145 are connected in sequence; and the first connecting rod 142 and the second connecting rod 145 respectively pass through the corresponding side wall of the gap 110 and extend into the corresponding sliding hole 120; the connections between the first connecting rod 142, the first articulated rod 143, the second articulated rod 144 and the second connecting rod 145 are connected by a universal joint; during discharging, the first connecting rod 142, the first articulated rod 143, the second articulated rod 144 and the second connecting rod 145 are on the same axis; after the end of stacking, the first articulated rod 143 and / or the second articulated rod 144 are pushed by an external force (the pushing direction is shown as F1 in Figure 2 ), so as to retract the first connecting rod 142 and the second connecting rod 145 (the retraction direction is shown as F2 in Figure 2 ), thereby driving the corresponding adjustment plate 141 to retract.

[0074] The first connecting rod 142, the first articulated rod 143, the second articulated rod 144 and the second connecting rod 145 are connected in a universal joint manner; when it is necessary to retract the first connecting rod 142 and the second connecting rod 145, the first articulated rod 143 and the second articulated rod 144 are pushed by an external force, thereby pulling the first connecting rod 142 and the second connecting rod 145 to retract.

[0075] In order to reset the first articulated rod 143 and the second articulated rod 144, in a preferred embodiment, reset spring pieces are arranged at the connections of the first articulated rod 143 and the second articulated rod 144; after the external force is removed, the reset spring pieces drive the first articulated rod 143 and the second articulated rod 144 to reset.

[0076] Please continue to refer to Figure 2 , the sliding hole 120 is provided with an embedding groove 121 on the side close to the gap 110; the adjustment plate 141 is arranged in the embedding groove 121. The groove wall of the embedding groove 121 radially restricts the adjustment plate 141, thereby avoiding the deviation of the adjustment plate 141.

[0077] Please refer to Figure 1 and Figure 3The buffer clamping piece 300 comprises: a buffer plate 310, one end of which is rotatably arranged on the upper part of the clamping plate 200 through a rotating shaft, and the other end of which is elastically connected with the clamping surface 210 of the clamping plate 200 through a return spring 330; a flexible belt 320, one end of which is connected with the buffer plate 310, and the other end of which is connected with the trigger adjusting piece 140 after passing over the bottom of the clamping plate 200; and the flexible belt 320 covers the surface of the buffer plate 310.

[0078] The falling of the photovoltaic cell 400 is buffered by the flexible belt 320, and meanwhile, the photovoltaic cell 400 is prevented from being in hard contact with the clamping plate 200 and the buffer plate 310, so that the photovoltaic cell 400 is protected.

[0079] Please refer to Figure 4 and Figure 5 After the stacking is completed, the two ends of the trigger adjusting piece 140 are first pushed to be in the retracted state by an external force, so as to drive the adjusting plates 141 at the two ends to be separated from the side wall of the sliding bolt rod 130, then the clamping plate 200 is pushed by an external force to clamp the stacked photovoltaic cells 400, and the trigger adjusting piece 140 is pulled by the flexible belt 320, so that the two ends of the trigger adjusting piece 140 are in the retracted state, so as to adjust the position of the clamping plate 200.

[0080] After the stacking is completed, the position of the clamping plate 200 is first adjusted by an external force to release the limiting of the sliding bolt rod 130, at this time, the clamping plate 200 is pushed by an external force (the pushing direction is shown as F in Figure 4 At this time, the retracted state of the trigger adjusting piece 140 is maintained by the flexible belt 320, and meanwhile, the flexible belt 320 pulls the buffer plate 310 to retract, so that the bottom end of the buffer plate 310 is in abutment with the top surface of the top photovoltaic cell 400 of the stacked photovoltaic cells 400 (as shown in Figure 5 ), so as to limit the vertical direction of the photovoltaic cell 400.

[0081] The buffer clamping piece 300 is used to limit the vertical direction, without the need to add a pressing rod or a pressing cover for limiting, so as to avoid the photovoltaic cells from shaking during the conveying process.

[0082] Please refer to Figure 4 The minimum distance between the buffer surfaces between the two buffer clamping pieces 300 arranged oppositely is L1, and the width of the photovoltaic cell 400 is L2, wherein L2>L1.

[0083] By limiting the sizes of L1 and L2, L2 is greater than L1, so that the buffer plate 310 is provided with a deformation space. Meanwhile, it is ensured that the buffer plate 310 can extend to the top surface of the photovoltaic cell 400, so as to buffer the next photovoltaic cell 400.

[0084] Referring to Figure 6 The embodiment of the present disclosure also provides a working method applied to the stacking tool for photovoltaic cell pieces.

[0085] S110: adjusting the position of the clamping plate 200 to expand the stacking space outwardly;

[0086] S120: sequentially placing the photovoltaic cell pieces 400 into the stacking space along the vertical direction and buffering the photovoltaic cell pieces 400 through the buffer clamping piece 300;

Through the buffer clamping piece 300 arranged on the clamping plate 200, the impact force is actively absorbed during the falling of the photovoltaic cell pieces 400, avoiding the direct collision between the photovoltaic cell pieces 400 and the hard clamping plate 200, significantly reducing the risk of corner breakage and hidden cracks of the photovoltaic cell pieces 400, and after the stacking is completed, the position of the clamping plate 200 is adjusted through external force to switch the buffer clamping piece 300 from the buffering state to the clamping state, the buffer clamping piece 300 is deformed after being extruded and tightly adheres to the side of the photovoltaic cell pieces 400, providing uniform clamping force, overcoming the clamping looseness problem caused by the reserved deformation space of the traditional elastic pad layer, and ensuring the overall stability of the stacking.
