Description

Technical Field

[0001] This utility model relates to the field of battery cell stringing technology, and in particular to a solder ribbon placement platform. Background Technology

[0002] When photovoltaic module cells are produced in strings, solder ribbons need to be placed on the surface of the cells and fixed to the surface of the cells, and attached to the grid lines on the surface of the cells, so as to conduct the current generated by the cells.

[0003] Before transferring the solder ribbon to the solar cells, the solder ribbon needs to be placed on the solder ribbon placement platform, and both ends of the solder ribbon need to be clamped. The solder ribbon is then cut to the required length on the solder ribbon placement platform to facilitate the connection between solar cells.

[0004] In existing technologies, the welding strip is generally cut from top to bottom. This cutting method causes the welding strip to bend towards the direction of the battery cell or away from the battery cell. When straightening the welding strip, the battery cell is easily crushed.

[0005] Therefore, there is an urgent need for a solder strip placement platform that can prevent the solder strip from bending toward or away from the solar cell during the cutting process, thus facilitating the correction of the solder strip and reducing the probability of the solar cell being crushed. Summary of the Invention

[0006] The purpose of this invention is to solve the problem that the bending direction of the welding strip towards or away from the battery cell during the correction process can easily crush the battery cell. It provides a welding strip placement platform that can prevent the welding strip from bending towards or away from the battery cell during the cutting process, thus facilitating the correction of the welding strip and reducing the probability of the battery cell being crushed.

The horizontal limiting block passes through the first horizontal limiting groove and the second horizontal limiting hole to restrict the paths of the first blade and the second blade to the horizontal plane.

[0023] According to an example embodiment of the present invention, the receiving plate is provided with four clamping grooves, namely a first clamping groove, a second clamping groove, a third clamping groove, and a fourth clamping groove.

[0044] The following example describes a welding strip placement platform of this utility model. This example is only a part of the embodiments of this utility model, but the protection scope of this utility model is not limited thereto. All other embodiments obtained by those skilled in the art without inventive effort should be covered within the protection scope of this utility model.

[0045] As the first embodiment of this utility model, a solder strip placement platform is provided, such as... Figure 1 and Figure 2 As shown, it includes: a receiving plate 1, a welding strip clamping mechanism 3, a cutting blade 2, and a circulating drive mechanism.

[0046] The receiving plate 1 consists of two horizontally placed pieces for holding the welding strip. The receiving plate 1 includes four clamping grooves, a cutting groove 15, and a receiving plate body 16. The cutting groove 15 is located in the middle of the receiving plate body 16, and its length direction is perpendicular to the length direction of the welding strip. The length of the cutting groove 15 is longer than the width of the welding strip. The four clamping grooves are a first clamping groove 11, a second clamping groove 12, a third clamping groove 13, and a fourth clamping groove 14. The length directions of the first clamping groove 11, the second clamping groove 12, the third clamping groove 13, and the fourth clamping groove 14 are all perpendicular to the length direction of the welding strip, and their lengths are all longer than the width of the welding strip. The first clamping groove 11 and the second clamping groove 12 are located on one side of the cutting blade groove 15, and the third clamping groove 13 and the fourth clamping groove 14 are located on the other side of the cutting blade groove 15. The second clamping groove 12 is located between the first clamping groove 11 and the cutting blade groove 15. The second clamping groove 12 and the third clamping groove 13 are set close to the cutting blade groove 15.

[0047] like Figure 1 and Figure 2 As shown, the cutting blade 2 is located in the middle of the receiving plate 1, perpendicular to the length direction of the welding strip. The lower part of the cutting blade 2 is confined within the cutting blade groove 15, and the upper part is the cutting portion located above the receiving plate 1. Figure 3 and Figure 4 As shown, the cutting blade includes a first blade 21, a second blade 22, a cutting moving roller 23, and a horizontal limiting block 24. One side of the first blade 21 and one side of the second blade 22 slide against each other. When the first blade 21 and the second blade 22 slide along the length direction of the cutting groove 15, the first blade 21 and the second blade 22 slide in opposite directions in a horizontal and perpendicular direction to the length of the welding strip to cut the welding strip.

[0048] like Figure 5 As shown, the first blade 21 has a first moving hole 211, a first horizontal limiting groove 212, a first cutting groove 213, and a first cutting edge 214. The lower part of the first blade 21 is limited within the cutting groove 15, and the upper part is the cutting portion. The top of the first blade 21 is provided with multiple first cutting grooves 213, through which the welding strip passes. The first cutting edge 214 is vertically arranged on the groove wall of the first cutting groove 213. The upper part of the first moving hole 211 is a vertical hole, and the lower part is a round hole; or the upper part of the first moving hole is a round hole, and the lower part is a vertical hole.

[0049] like Figure 6As shown, the second blade 22 has a second moving hole 221, a second horizontal limiting hole 222, a second cutting groove 223, and a second cutting edge 224. The lower part of the second blade 22 is limited within the cutting groove 15, and the upper part is the cutting portion. The top of the second blade 22 is provided with multiple second cutting grooves 223, through which the welding strip passes. The second cutting edge 224 is vertically set on the groove wall of the second cutting groove 223. When the upper part of the first moving hole 211 is set as a vertical hole and the lower part as a round hole, the upper part of the second moving hole 221 is set as a round hole and the lower part as a vertical hole; when the upper part of the first moving hole 211 is set as a round hole and the lower part as a vertical hole, the upper part of the second moving hole 221 is set as a vertical hole and the lower part as a round hole.

[0050] The axial direction of the cutting moving roller 23 is the same as the length direction of the welding strip, such as... Figure 6 and Figure 7 As shown, the cutting moving roller 23 sequentially includes an abutment portion 231, a limiting portion 232, and a roller shaft 233. The limiting portion 232 is in contact with one side of the first blade 21 or the second blade 22, and the roller shaft 233 is connected to the rotating mechanism, driving the abutment portion 231 to rotate. The abutment portion 231 passes through the first moving hole 211 and the second moving hole 221. The abutment portion 231 has a centrally symmetrical structure, with the center of symmetry located on the axis of the cutting moving roller 23. The upper part of the abutment portion 231 is always in contact with the wall of the first moving hole 211, and the lower part is always in contact with the wall of the second moving hole 221; or the upper part of the abutment portion 231 is always in contact with the wall of the second moving hole 221, and the lower part is always in contact with the wall of the first moving hole 211. When the cutting moving roller 23 rotates, it drives the first blade 21 and the second blade 22 to slide in opposite directions to achieve cutting.

[0051] Specifically, the contact portion 231 has a figure-eight shape on the surface perpendicular to the axial direction of the cutting moving roller 23, and the center of symmetry of the figure-eight shape is located on the axis of the cutting moving roller 23.

[0052] When the upper part of the first moving hole 211 is set as a circular hole and the lower part as a vertical hole, the wall of the circular hole of the first moving hole 211 is located on the rotation trajectory of the upper part of the abutment part 231 (that is, the inner wall of the circular hole coincides with the rotation path of the outermost end of the upper part of the abutment part 231), and the upper part of the abutment part 231 is always in contact with the wall of the circular hole, and the wall of the vertical hole of the first moving hole 211 is always in contact with the lower part of the abutment part; when the upper part of the second moving hole 221 is set as a vertical hole and the lower part as a circular hole, the wall of the vertical hole of the second moving hole is always in contact with the upper part of the abutment part, and the wall of the circular hole of the second moving hole 211 is located on the rotation trajectory of the lower part of the abutment part 231 (that is, the inner wall of the circular hole coincides with the rotation path of the outermost end of the lower part of the abutment part 231), and the lower part of the abutment part 231 is always in contact with the wall of the circular hole.

[0053] When the upper part of the first moving hole 211 is set as a vertical hole and the lower part is set as a circular hole, the vertical hole of the first moving hole 211 always abuts against the upper part of the abutting part, and the hole wall of the circular hole of the first moving hole 211 is located on the rotation trajectory of the lower part of the abutting part 231 (that is, the inner wall of the circular hole coincides with the rotation path of the outermost end of the lower part of the abutting part 231), and the lower part of the abutting part 231 always keeps in contact with the hole wall of the circular hole; when the upper part of the second moving hole 221 is set as a circular hole and the lower part is set as a vertical hole, the hole wall of the circular hole of the second moving hole 211 is located on the rotation trajectory of the upper part of the abutting part 231 (that is, the inner wall of the circular hole coincides with the rotation path of the outermost end of the upper part of the abutting part 231), and the upper part of the abutting part 231 always keeps in contact with the hole wall of the circular hole, and the vertical hole of the second moving hole 221 always abuts against the lower part of the abutting part.

[0054] By rotating the cutting moving roller 23, the first blade 21 and the second blade 22 are restricted by the first moving hole 211 on the first blade 21 and the second moving hole 221 on the second blade 22, respectively. The relative movement of the first blade 21 and the second blade 22 drives the first cutting groove 213 and the second cutting groove 223 on the first blade 21 and the second blade 22 to move relative to each other. The welding strip is abutted by the groove walls (i.e. the first cutting edge 214 and the second cutting edge 224) in the first blade 21 and the second blade 22. When the first cutting edge 214 and the second cutting edge 224 move to the point of intersection, the welding strip is cut off, thus completing the cutting of the welding strip.

[0055] The horizontal limiting block 24 passes through the first horizontal limiting groove 212 and the second horizontal limiting hole 222, restricting the paths of the first blade 21 and the second blade 22 to the horizontal plane. Specifically, as shown... Figure 3 and Figure 4As shown, the first horizontal limiting groove 212 is formed on the side of the first blade 21 facing away from the second blade 22, and the bottom of the groove is a through hole. The second horizontal limiting hole 222 is also a through hole structure, and the size of the through hole of the second horizontal limiting hole 222 in the direction perpendicular to the length of the weld strip is larger than the size of the through hole at the bottom of the first horizontal limiting groove 212. The horizontal limiting block 24 includes a limiting cap and a snap-fit ​​part. The limiting cap is located inside the first horizontal limiting groove 212, and the size of the limiting cap is larger than the size of the bottom of the groove. The snap-fit ​​part passes through the bottom of the groove and the through hole of the second horizontal limiting hole 222, and the size of the snap-fit ​​part is equivalent to the size of the through hole at the bottom of the first horizontal limiting groove 212. Because the size of the through hole of the second horizontal limiting hole 222 in the direction perpendicular to the length of the welding strip is larger than the size of the through hole at the bottom of the first horizontal limiting groove 212, there is a certain amount of space for the first blade 21 and the second blade 22 to move in opposite directions. Also, because the size of the snap-fit ​​part is equivalent to the size of the through hole at the bottom of the first horizontal limiting groove 212, the first blade 21 and the second blade 22 cannot move in the vertical direction. Therefore, the horizontal limiting block 24, the first horizontal limiting groove 212 and the second horizontal limiting hole 222 restrict the movement direction of the first blade 21 and the second blade 22 to a horizontal direction perpendicular to the length of the welding strip.

[0056] like Figure 1 and Figure 2 As shown, the welding strip clamping mechanism 3 is located on both sides of the cutting blade 2 and is used to clamp the welding strip. The welding strip clamping mechanism 3 includes four welding strip clamping claws, namely the first welding strip clamping claw 31, the second welding strip clamping claw 32, the third welding strip clamping claw 33, and the fourth welding strip clamping claw 34. Each welding strip clamping claw is confined to a clamping groove. The first welding strip clamping claw 31 is confined to the first clamping groove 11, the second welding strip clamping claw 32 is confined to the second clamping groove 12, the third welding strip clamping claw 33 is confined to the third clamping groove 13, and the fourth welding strip clamping claw 34 is confined to the fourth clamping groove 14. The width of each clamping groove is greater than the width of two welding strip clamping claws, so as to facilitate the other welding strip clamping claw to reach into the clamping groove and carry the welding strip to the next station.

[0057] This design sets the cutting blade 2 to cut horizontally. The first blade 21 and the second blade 22 move in opposite directions horizontally, cutting the solder strip through the groove wall of the first cutting groove 213 and the second cutting groove 223. This reduces the likelihood of the solder strip bending towards or away from the battery cell after cutting, facilitating solder strip correction and reducing the probability of the battery cell being crushed. The relative movement of the first blade 21 and the second blade 22 can be achieved by rotating the cutting moving roller 23, simplifying the driving of the first blade 21 and the second blade 22 and facilitating solder strip cutting.

[0058] like Figure 1 and Figure 2As shown, the cyclic drive mechanism 4 includes a longitudinal positioning platform 41 and two longitudinal moving frames 42. The two longitudinal moving frames 42 are fixedly connected to two receiving plates 1 respectively, and are used to drive the receiving plates 1 to move up and down. The two longitudinal moving frames 42 are arranged on both sides of the longitudinal positioning platform 41 and are slidably connected to the longitudinal positioning platform 41 to achieve horizontal sliding of the longitudinal moving frames 42. Horizontally arranged sliding rails are provided on both sides of the longitudinal positioning platform 41, and the length direction of the sliding rails is the same as the length direction of the welding strip. The longitudinal moving frame 42 includes a connecting part 421, a vertical slide rail 422, and a moving part 423. One side of the connecting part 421 is slidably connected to a sliding rail, the vertical slide rail 422 is fixed to the other side of the connecting part 421, the moving part 423 is slidably connected to the vertical slide rail 422, and the top of the moving part 423 is fixedly connected to the bottom of the receiving plate 1. The connecting part 421 slides on the movable slide rail, preferably driven by an electromagnetic pulse. That is, a number of electromagnets are arranged in the longitudinal positioning table 21 along the transport direction. When the electromagnets are energized in sequence, they attract the connecting part, thereby driving the connecting part 421. The moving part 423 slides on the vertical slide rail 422 and is driven by a cylinder. That is, a moving cylinder is connected to the bottom end of the moving part 423.

[0059] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
