[0002] Currently, during the production of solar cells, bus bars need to be welded to the cell wafers to facilitate fixing the cell wafers. The bus bars are generally in a strip structure wound around a carrier plate.

It can be understood that the specific embodiments described herein are only for explaining the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only the structural parts related to the present invention are shown in the drawings, rather than the entire structure.

It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0076] Currently, in the process of manufacturing solar cells, it is necessary to weld the bus bars to the cells to fix the cells. The bus bars are generally in a strip structure wound around a carrier plate. When welding the bus bars, the bus bars need to be cut into a predetermined length and then transported to a fixed position for welding. Therefore, a bus bar welding device has been proposed for automatically cutting and welding the bus bars.

[0077] Such as Figure 1As shown in the figure, this embodiment provides a bus bar welding device, which includes a first frame 100, a conveying device 200, and a horizontal preparation device 300. Among them, the conveying device 200 is arranged on the first frame 100, and the conveying device 200 is used to convey the horizontal bus bar 1000 and the vertical bus bar 2000 to the next working station, so as to realize the automatic conveying of the horizontal bus bar 1000 and the vertical bus bar 2000 between different working stations, which is beneficial to improving the working efficiency of the bus bar welding device. The horizontal bus bar 1000 extends along the X direction (the first direction), the vertical bus bar 2000 extends along the Y direction (the second direction), the horizontal preparation device 300 is arranged on the first frame 100, and the horizontal preparation device 300 is used to prepare the horizontal bus bar 1000 and transfer it to the conveying device 200. The horizontal preparation device 300 can realize the automatic preparation of the horizontal bus bar 1000, which is beneficial to improving the working efficiency of the bus bar welding device. Exemplarily, according to the relative positions of the horizontal bus bar 1000 and the vertical bus bar 2000 welded to the battery module, the X direction and the Y direction are perpendicular to each other.

[0078] The structure of the bus bar welding device is compact. The conveying device 200 runs through the whole bus bar welding device, and only through the movement of the conveying device 200, the connection of each process is realized, which is beneficial to simplifying the structure.

[0079] As Figure 2 and Figure 3 shown, specifically, the horizontal bus bar 1000 and the vertical bus bar 2000 are the whole bus bar. According to requirements, there are multiple horizontal bus bars 1000 in the whole bus bar. Exemplarily, the horizontal bus bar 1000 can include three or four, and the operator can selectively set according to requirements.

[0080] Please continue to refer to Figure 1 , in order to improve the preparation efficiency of the horizontal bus bar 1000, the horizontal preparation device 300 includes two groups, and the two groups of horizontal preparation devices 300 are arranged opposite to each other, so that two horizontal bus bars 1000 can be prepared simultaneously, thereby improving the working efficiency of the bus bar welding device.

[0081] As Figure 1 shown, during operation, if four horizontal bus bars 1000 are needed, the two horizontal preparation devices 300 respectively prepare two horizontal bus bars 1000, so as to halve the time between preparing the horizontal bus bars 1000, greatly improving the working efficiency. Of course, if three horizontal bus bars 1000 are needed, one of the horizontal preparation devices 300 prepares one, and the other group of horizontal preparation devices 300 prepares two horizontal bus bars 1000. This method is beneficial to reducing the preparation time by one-third, and can also achieve the purpose of improving the preparation efficiency of the horizontal bus bar 1000.

[0082] Please continue to refer to Figure 1 , further, the lateral preparation device 300 includes a lateral preparation mechanism 310 and a first transfer mechanism 320. Among them, the lateral preparation mechanism 310 is used to prepare the lateral bus bar 1000, and the first transfer mechanism 320 can transfer the lateral bus bar 1000 prepared by the lateral preparation mechanism 310 to the conveying device 200, so as to facilitate the automatic preparation and transfer of the lateral bus bar 1000.

[0083] Now in combination with Figure 4 the detailed structure of the first transfer mechanism 320 will be described.

[0084] As Figure 4 shown, the first transfer mechanism 320 includes a seventh frame 321, a fourth driving member 322, and a third grasping assembly 323. Among them, the seventh frame 321 is arranged on the first frame 100, the fourth driving member 322 is arranged on the seventh frame 321, the third grasping assembly 323 is arranged at the output end of the fourth driving member 322, and the fourth driving member 322 can drive the third grasping assembly 323 to move in a direction close to or away from the lateral bus bar 1000, so as to achieve the purpose of grasping the lateral bus bar 1000.

[0085] Please continue to refer to Figure 4 , specifically, the third grasping assembly 323 includes a grasping bracket 3231 and a grasping member 3232. The grasping bracket 3231 is connected to the output end of the fourth driving member 322, and the grasping member 3232 is arranged on the grasping bracket 3231 for grasping the lateral bus bar 1000. Specifically, the grasping member 3232 is communicated with a vacuum generating device, and the lateral bus bar 1000 is grasped by the vacuum adsorption method, which is beneficial to ensuring the stability of grasping the bus bar.

[0086] Please continue to refer to Figure 4 , further, the first transfer mechanism 320 further includes a fifth driving member 324 and a fourth guiding assembly 325. The fifth driving member 324 is arranged on the first frame 100, the third guiding assembly is arranged between the first frame 100 and the seventh frame 321, and the seventh frame 321 is arranged at the output end of the fifth driving member 324, so that the fifth driving member 324 can drive the seventh frame 321 to reciprocate in the direction of the lateral preparation mechanism 310 moving towards the conveying device 200, so as to transfer the prepared lateral bus bar 1000 to the conveying device 200.

[0087] Please continue to refer to Figure 4, specifically, the fourth guiding component 325 includes a third guide rail and a third slider. The third guide rail is arranged along the Y direction, and the third slider is slidably connected to the third guide rail. The third guide rail is arranged on the first frame 100, and the third slider is arranged on the seventh frame 321, thereby improving the stability of the seventh frame 321 moving along the Y direction and avoiding jamming.

[0088] It can be understood that since there are two sets of the transverse preparation mechanisms 310, in order to ensure the transfer efficiency, there are also two sets of the first transfer mechanisms 320. The two sets of the first transfer mechanisms 320 transfer the transverse busbars 1000 prepared by the two transverse preparation mechanisms 310 at the same time, which is beneficial to improving the working efficiency.

[0089] As Figures 2 to 4 shown, further, since in the existing battery modules, generally more than three transverse busbars 1000 need to be welded. In order to further improve the transfer efficiency, two sets of the first transfer mechanisms 320 are correspondingly arranged for each set of the transverse preparation mechanisms 310. When four transverse busbars 1000 are needed, each set of the transverse preparation mechanisms 310 prepares two transverse busbars 1000. After the transverse preparation mechanism 310 completes the two transverse busbars 1000, the two first transfer mechanisms 320 can transfer them at the same time, further improving the transfer efficiency. It can be understood that when three transverse busbars 1000 need to be prepared, one of the transverse preparation mechanisms 310 prepares two, and the other transverse preparation mechanism 310 prepares one. Then when transferring the transverse busbars 1000, the two first transfer mechanisms 320 in one group work simultaneously, and only one of the two first transfer mechanisms 320 in the other group needs to work. The first transfer mechanism 320 is flexible in operation, has strong applicability, and is beneficial to improving the working efficiency.

[0090] As Figures 5 to 6 shown, the transverse preparation device 300 further includes a transfer platform 330. Now, in combination with Figures 5 to 6 the detailed structure of the transfer platform 330 will be described.

[0091] As Figure 5 shown, the transfer platform 330 is arranged between the transverse preparation mechanism 310 and the conveying device 200. The transfer platform 330 is used to carry the transverse busbars 1000 completed by the transverse preparation mechanism 310, so as to wait for the transverse preparation mechanism 310 to prepare other transverse busbars 1000. Then the first transfer mechanism 320 grabs all the transverse busbars 1000 from the transfer platform 330. When the first transfer mechanism 320 transfers the transverse busbars 1000, the transverse preparation mechanism 310 can still prepare the transverse busbars 1000, realizing the simultaneous progress of the preparation work of the transverse preparation mechanism 310 and the transfer action of the first transfer mechanism 320, which is beneficial to improving the working efficiency.

[0092] As Figures 5 to 6As shown in the figure, specifically, the transfer platform 330 includes a first mounting bracket 331 and a plurality of first carrier brackets 332. Among them, the first mounting bracket 331 is disposed on the first frame body 100, and the plurality of first carrier brackets 332 are arranged in parallel and at intervals to facilitate the loading of a plurality of horizontal busbars 1000, so as to facilitate the transfer by the first transfer mechanism 320 and reduce the waiting time of the horizontal preparation mechanism 310 or the conveying device 200. Exemplarily, after the horizontal preparation mechanism 310 prepares a horizontal busbar 1000, the first transfer mechanism 320 places it on the transfer platform 330, and then can continue to prepare the next one. At this time, the first transfer mechanism 320 can sequentially transfer the horizontal busbars 1000.

[0093] As Figures 5 to 6 shown, further, the first carrier bracket 332 includes a first carrier body 3321 and a plurality of first limiting members 3322. Among them, the first carrier body 3321 is disposed on the first mounting bracket 331, and the plurality of first limiting members 3322 are divided into multiple groups. Each group of first limiting members 3322 includes two, and the two first limiting members 3322 are arranged at intervals on the first carrier body 3321. The multiple groups of first limiting members 3322 are arranged in parallel and at intervals. The horizontal busbar 1000 can pass through the interval between each group of first limiting members 3322, so as to prevent the horizontal busbar 1000 from falling off the first carrier bracket 332, thereby improving the stability and safety of the transfer process. Exemplarily, the busbar is a copper strip, and the copper strip is a flat strip structure. The prepared horizontal busbar 1000 can be placed flat between the two first limiting members 3322, and its positions on both sides are restricted by the two first limiting members 3322 to extend along the X direction.

[0094] As Figure 6 shown, in order to improve the stability of fixing the horizontal busbar 1000, a plurality of first adsorption holes 3323 are formed on the first carrier bracket 332. The plurality of first adsorption holes 3323 are arranged along the extending direction of the first carrier bracket 332. The first adsorption holes 3323 can be communicated with a vacuum generating device to facilitate the adsorption of the horizontal busbar 1000, improve the stability of fixing the horizontal busbar 1000, and prevent it from falling.

[0095] Of course, the horizontal preparation device 300 further includes a feeding mechanism (not shown in the figure) for releasing the carried horizontal bus bar 1000 to the horizontal preparation mechanism 310. To reduce the occupied space, the feeding mechanism of the horizontal preparation device 300 can be arranged outside the bus bar welding equipment, which is beneficial to save space. To further improve the stability of the horizontal preparation device 300, two feeding mechanisms can be provided for each horizontal preparation mechanism 310, with one feeding mechanism arranged at the lower left and the other at the right, thereby saving the floor space of the feeding mechanism. And when a feeding mechanism fails, the other can ensure the smooth operation of the equipment. Exemplarily, the driving member of the feeding mechanism is preferably a stepping motor driving member, which has good accuracy and is beneficial to improving the accuracy of the feeding size.

[0096] Since the bus bar is a long strip of copper tape, it is easy to become thinner or break under the stretching of the preparation mechanism. In this embodiment, the horizontal preparation device 300 further includes a buffer mechanism 340, which is arranged between the feeding mechanism and the preparation of the horizontal bus bar 1000 and is used to buffer a preset length of the bus bar. Now, in combination with Figure 7 the detailed structure of the buffer mechanism 340 will be described.

[0097] As Figure 7 shown, the buffer mechanism 340 includes a fourth frame 341, a first fixed pulley 343, and two moving pulleys 342 arranged at intervals. Among them, both of the two moving pulleys 342 can move along the Z direction (the third direction), and the moving directions of the two moving pulleys 342 are the same. The first fixed pulley 343 is arranged between the two moving pulleys 342, and the horizontal bus bar 1000 bypasses one of the moving pulleys 342, the first fixed pulley 343, and the other moving pulley 342 in sequence. This buffer mechanism 340 uses the distance between the two moving pulleys 342 and the first fixed pulley 343, the distance from the input end of the horizontal bus bar 1000 of the buffer mechanism 340 to the first moving pulley 342, and the distance from the second moving pulley 342 to the output end of the horizontal bus bar 1000 of the buffer mechanism 340, these four distances to buffer the horizontal bus bar 1000, so as to adjust the speed difference between the input speed and the output speed of the horizontal bus bar 1000 input at both ends of the buffer mechanism 340, to avoid problems such as thinning or breaking of the horizontal bus bar 1000 due to excessive stretching at the output end. At the same time, this buffer mechanism 340 has four distances for buffering the horizontal bus bar 1000. Under the condition of the same size, the buffering length increases, which is beneficial to saving the floor space of the buffer mechanism 340 and expanding the applicable range. This buffer mechanism 340 also has the function of straightening the horizontal bus bar 1000.

[0098] Please continue to refer to Figure 7, Further, the buffer mechanism 340 further includes a first guiding component 344 disposed between the moving wheels 342 and the fourth frame 341. The first guiding component 344 can guide the movement of the moving wheels 342 in the third direction, so as to improve the stability of the moving wheels 342 moving in the Z direction and prevent the lateral bus bar 1000 from being deformed or broken due to the shaking of the moving wheels 342 during movement.

[0099] Please continue to refer to Figure 7 , Specifically, the first guiding component 344 includes a first guide rail 3441 and a first slider 3442. The first guide rail 3441 is disposed on the fourth frame 341 along the Z direction, the first slider 3442 is slidably connected to the first guide rail 3441, and the two moving wheels 342 are both disposed on the first slider 3442, and the two moving wheels 342 can rotate relative to the first slider 3442. At this time, the two moving wheels 342 are both disposed on the first slider 3442, so that the two moving wheels 342 can move in the Z direction simultaneously, reducing the linkage force of the lateral bus bar 1000 between the two moving wheels 342, which is beneficial to further ensure the quality of the lateral bus bar 1000 and avoid damage.

[0100] In other embodiments, the first guiding component 344 includes two first guide rails 3441 and two first sliders 3442. The two first guide rails 3441 are arranged in parallel and at intervals, and the first guide rail 3441 is disposed on the fourth frame 341 along the Z direction. The two first sliders 3442 are respectively slidably connected to the two first guide rails 3441, and the two moving wheels 342 are arranged in one-to-one correspondence with the two first sliders 3442. The moving wheels 342 are rotatably disposed on the first sliders 3442. The structure of the first guiding component 344 is simple, which is convenient for the operator to assemble and maintain. And the two moving wheels 342 can move upward or downward independently in the Z direction respectively, so as to achieve the effect of releasing the buffer.

[0101] As Figure 7 shown, as an alternative, the initial position of the moving wheels 342 is located at the middle position of the moving range of the moving wheels 342 in the Z direction, so that the two moving wheels 342 have moving space both upward and downward in the Z direction. Of course, in other embodiments, the initial position of the moving wheels 342 can also be located at the lowermost end.

[0102] When the stretching speed of the bus bar by the downstream of the buffer mechanism 340 (i.e., the lateral preparation mechanism 310) is greater than the releasing speed of the bus bar by the upstream of the buffer mechanism 340 (i.e., the feeding mechanism), the two fixed wheels can move upward in the Z direction simultaneously to release the bus bar on the buffer mechanism 340, so that the required length of the bus bar stretched by the bus bar preparation mechanism can be fully supplied, and damage to the lateral bus bar 1000 caused by too large a speed difference can be avoided.

[0103] Of course, when the speed at which the downstream of the buffer mechanism 340 (i.e., the horizontal preparation mechanism 310) stretches the bus bar is greater than the speed at which the upstream of the buffer mechanism 340 (i.e., the feeding mechanism) releases the bus bar, the two fixed wheels can move simultaneously in the negative direction of the third direction to release the bus bar on the buffer mechanism 340. That is, the buffer mechanism 340 can adjust the length of its buffer by adjusting the position of the fixed wheels in the Z direction, so as to absorb the extra length released by the feeding mechanism, thus achieving the effect of ensuring the stable operation of the horizontal preparation device 300.

[0104] As Figure 7 shown, as an alternative solution, the buffer mechanism 340 further includes a second fixed wheel 345 disposed on the fourth frame 341, and the first fixed wheel 343 is rotatably connected to the fourth frame 341. The bus bar is introduced from the second fixed wheel 345 onto the moving wheel 342, thereby improving the stability of introducing the horizontal bus bar 1000 onto the moving wheel 342. At the same time, the second fixed wheel 345 also has the effect of redirecting the introducing direction.

[0105] Please continue to refer to Figure 7 , it can be understood that the buffer mechanism 340 further includes a third fixed wheel 346 disposed on the fourth frame 341, and the third fixed wheel 346 is rotatably connected to the fourth frame 341. The bus bar is led out from the second fixed wheel 345 after passing through the two moving wheels 342, thereby improving the stability of the output of the horizontal bus bar 1000 from the moving wheels 342. At the same time, the third fixed wheel 346 also has the effect of redirecting the output direction.

[0106] In the prior art, the bus bar welded to the battery module includes a horizontal bus bar 1000 and a vertical bus bar 2000, and the horizontal bus bar 1000 and the vertical bus bar need to be welded together after passing through the preparation device 400, and then welded to the battery cell. The existing bus bar welding equipment can only prepare the horizontal bus bar 1000, and then the vertical bus bar 2000 needs to be prepared separately and bent and welded to the horizontal bus bar 1000, resulting in complex processes and long time consumption for welding the bus bar to the battery module.

[0107] To solve the above problems, the bus bar welding equipment in this embodiment further includes a vertical preparation device 400. The vertical preparation device 400 is disposed on the first frame 100, and the vertical preparation device 400 is used to prepare the vertical bus bar 2000 and transfer it to the conveying device 200. The vertical preparation device 400 includes a welding mechanism 430, and the welding mechanism 430 is used to weld the horizontal bus bar 1000 and the vertical bus bar 2000 carried by the conveying device 200 to the workpiece. This bus bar welding equipment can realize the simultaneous completion of the vertical bus bar 2000 and the horizontal bus bar 1000 on the same production line, reduce the production process, simplify the processing process of the battery module, and improve the production efficiency.

[0108] Now in combination withFigures 7 to 8 , the detailed structure of the vertical preparation device 400 will be described.

[0109] As shown in Figures 7 to 8 , the vertical busbar preparation device 400 includes a vertical busbar preparation mechanism 410 and a second transfer mechanism 420. Among them, the vertical preparation mechanism 410 is used to prepare the vertical busbar 2000, and the second transfer mechanism 420 can transfer the vertical busbar 2000 prepared by the vertical preparation mechanism 410 to the conveying device 200, thereby realizing the automatic preparation and transfer of the vertical busbar 2000, which is beneficial to improving the efficiency of the vertical busbar preparation device 400.

[0110] Since the vertical busbar 2000 generally includes multiple segments of vertical busbars 2000, and the lengths of the multiple segments of vertical busbars 2000 are not exactly the same. As Figure 8 shown, the vertical busbar 2000 in this embodiment includes two short busbars and two long busbars. The two long busbars are arranged in sequence, and the two short busbars are respectively arranged at both ends of the two short busbars, and the connection positions of adjacent two busbars are bent.

[0111] Please continue to refer to Figure 8 , in order to further improve the efficiency of the vertical busbar preparation device 400, the vertical preparation mechanism 410 and the second transfer mechanism 420 are respectively two groups, and the two groups of vertical preparation mechanisms 410 are arranged in parallel and opposite to each other. The two groups of vertical preparation mechanisms 410 can respectively prepare all or part of the short busbars and long busbars. Specifically, the stretching direction of one group of vertical preparation mechanisms 410 is in one direction along the Y direction, and the stretching direction of the other group of vertical preparation mechanisms 410 is in the other direction along the Y direction, so that the two vertical preparation mechanisms 410 respectively prepare from both ends of the vertical busbar 2000 to the middle in sequence. This vertical preparation mechanism 410 is beneficial to improving the preparation efficiency, facilitating the second transfer mechanism 420 to transfer the vertical busbar 2000, and the two vertical preparation mechanisms 410 stretch relatively, which is convenient for splicing and assembling the vertical busbars 2000 prepared by the two groups of vertical preparation mechanisms 410, and improves the efficiency for transfer and splicing.

[0112] If the vertical busbar 2000 includes three segments, then one group of vertical preparation mechanisms 410 prepares one long busbar and one short busbar, and the other group of vertical preparation mechanisms 410 only needs to prepare one of them, and the length of the group of vertical preparation mechanisms 410 for preparing one segment of the vertical busbar 2000 is shorter, which is beneficial to saving space and reducing costs. The design of this vertical preparation mechanism 410 is beneficial to improving the production efficiency.

[0113] Now in combination with Figures 9 to 10 the detailed structure of the vertical preparation mechanism 410 will be described.

[0114] AsFigure 9 As shown, the vertical preparation mechanism 410 includes a stretching assembly 411, a fourth carrier 412, and a cutting assembly 413. Among them, the stretching assembly 411 is used to stretch the vertical bus bar 2000, the fourth carrier 412 is used to carry the vertical bus bar 2000 output by the stretching assembly 411, and after the fourth carrier 412 carries the bus bar of the preset length, the cutting assembly 413 can cut the bus bar. The vertical preparation mechanism 410 can realize the automatic stretching and cutting of the vertical bus bar 2000, thereby improving the preparation efficiency.

[0115] As Figure 9 and Figure 10 shown, the fourth carrier 412 includes a third carrier body 4121 and a plurality of third limit members 4122. Among them, the third carrier body 4121 is arranged downstream of the stretching assembly 411, the third carrier body 4121 is used to carry the vertical bus bar 2000, the plurality of third limit members 4122 are oppositely arranged on the third carrier body 4121, the plurality of third limit members 4122 are divided into multiple groups, the multiple groups of third limit members 4122 are arranged in parallel and at intervals, each group of third limit members 4122 includes two third limit members 4122, and the two third limit members 4122 are arranged at intervals, and the vertical bus bar 2000 can be arranged between the two third limit members 4122 so that the vertical bus bar 2000 extends along the Y direction. The vertical bus bar 2000 can pass through the interval of each group of third limit members 4122, thereby preventing the vertical bus bar 1000 from falling off the fourth carrier 412, and further improving the stability and safety of carrying the vertical bus bar 2000.

[0116] In order to improve the stability of fixing the vertical bus bar 2000, a plurality of second adsorption holes are formed on the fourth carrier 412, the plurality of second adsorption holes are arranged along the extending direction of the fourth carrier 412, and the second adsorption holes can be communicated with a vacuum generating device to facilitate the adsorption of the vertical bus bar 2000, improve the stability of fixing the vertical bus bar 2000, and prevent it from falling.

[0117] As Figure 10 shown, further, the vertical preparation mechanism 410 further includes a bending assembly 415 and at least two second pressing assemblies 414. Among them, at least two second pressing assemblies 414 are used to press and fix the vertical bus bar 2000, the bending assembly 415 is arranged on the fourth carrier 412, and the bending assembly 415 is arranged between the second pressing assemblies 414, and the bending assembly 415 is used to bend the bus bar. The vertical bus bar 2000 is fixed by the second pressing assembly 414 to prevent it from moving. The bending assembly 415 is used to bend the bus bar so as to form a preset shape of the vertical bus bar 2000, avoid manual bending, reduce labor costs, and improve the forming efficiency of the vertical bus bar 2000.

[0118] Please continue to refer toFigure 10 Specifically, the bending assembly 415 includes a bending driving member 4151 and a bending member 4152. The bending driving member 4151 is disposed on the first frame 100, and the bending member 4152 is disposed at the output end of the bending driving member 4151. The bending driving member 4151 can drive the bending member 4152 to move along the third direction to bend the bus bar. This bending mechanism can achieve the bending of the positions between adjacent segments of the vertical bus bar 2000 to meet the applicable requirements.

[0119] Please continue to refer to Figure 10 To further improve the stability of the vertical bus bar 2000 and prevent the vertical bus bar 2000 from shifting during the bending process, the vertical preparation mechanism 410 further includes a clamping assembly 416 for clamping and fixing the vertical bus bar 2000. Specifically, the clamping assembly 416 includes a clamping driving member 4161 and two relatively arranged clamping members 4162. The clamping driving member 4161 can drive the two clamping members 4162 to relatively approach and clamp the vertical bus bar 2000, or drive the two clamping members 4162 to move away from each other to release the vertical bus bar 2000.

[0120] Now in combination with Figure 11 the detailed mechanism of the second transfer mechanism 420 will be described.

[0121] As Figure 11 shown, the second transfer mechanism 420 includes a sixth frame 421, a second driving member 422, and a second grasping assembly 423. Among them, the sixth frame 421 is disposed on the first frame 100, the second driving member 422 is disposed on the sixth frame 421, and the second grasping assembly 423 is disposed at the output end of the second driving member 422. The first driving member 620 can drive the second grasping assembly 423 to move along the direction close to or away from the vertical bus bar 2000 to grasp the vertical bus bar 2000. This second transfer mechanism 420 can achieve the grasping and transfer of the vertical bus bar 2000.

[0122] Please continue to refer to Figure 11 Furthermore, the second transfer mechanism 420 further includes a third driving member 424 and a third guiding assembly 425. Among them, the third driving member 424 is disposed on the first frame 100, and the third driving member 424 is used to drive the sixth frame 421 to move along the first direction to transfer the vertical bus bar 2000 to the next working station. The third guiding assembly 425 is disposed between the third driving member 424 and the sixth frame 421 to provide guidance for the movement of the sixth frame 421 along the first direction, thereby improving the stability and accuracy of the process of transferring the vertical bus bar 2000.

[0123] Please continue to refer to Figure 11, Further, the vertical preparation device 400 further includes a welding mechanism 430. The welding mechanism 430 is disposed on the second transfer mechanism 420. The welding mechanism 430 is capable of welding and fixing the horizontal bus bar 1000 and the vertical bus bar 2000. The vertical preparation device 400 can realize the integrated setting of the vertical preparation device 400 and the welding, which is beneficial to simplifying the structure of the bus bar welding equipment and improving the efficiency of welding and fixing the bus bar.

[0124] It can be understood that the vertical preparation device 400 further includes a buffer mechanism 340 for buffering the vertical bus bar 2000 with a preset length, so as to avoid the situation that the vertical bus bar 2000 is thinned or broken during the process of the vertical preparation device 400, which is beneficial to ensuring the stability and precision of the preparation process.

[0125] As Figure 7 and Figure 12 shown, specifically, the buffer mechanism 340 may include two moving wheels 342 or one moving wheel 342, which rotate according to the set space size, and the specific structure of the buffer mechanism 340 is the same as that of the buffer mechanism 340 of the horizontal preparation device 300. Among them, the buffer mechanism 340 with one moving wheel 342 is applicable to the situation where the stroke is long enough and the space is sufficient.

[0126] Now in combination with Figures 13 to 14 the detailed structure of the conveying device 200 will be described.

[0127] As shown in Figures 13 to 14 , after the horizontal bus bar 1000 and the vertical bus bar 2000 are welded and fixed, they are collectively referred to as the bus bar assembly. For the convenience of conveying the bus bar assembly, the conveying device 200 includes a conveying driving member and a tooling mechanism 210. Among them, the tooling mechanism 210 is used to carry the bus bar assembly. The conveying driving member is disposed on the first frame 100, and the tooling mechanism 210 is disposed at the output end of the conveying driving member. The conveying driving member is used to drive the tooling mechanism 210 to move along the X direction, so as to realize the transfer of the bus bar assembly between each station of the bus bar welding equipment.

[0128] During operation, first, the first transfer mechanism 320 transfers the horizontal bus bar 1000 prepared by the horizontal preparation mechanism 310 to the tooling mechanism 210, and then the conveying driving member drives the tooling mechanism 210 to move to the next station. Then, the second transfer mechanism 420 transfers the vertical bus bar 2000 prepared by the vertical preparation mechanism 410 to the tooling mechanism 210, and the welding mechanism 430 performs welding and fixing. Finally, the conveying driving member conveys the tooling mechanism 210 to the subsequent station again, realizing the connection of the tooling mechanism 210 between multiple stations of the bus bar welder, so as to facilitate the conveying of the bus bar, which is beneficial to improving the production efficiency.

[0129] Now in combination withFigures 13 to 18 Describe the detailed structure of the tooling mechanism 210.

[0130] As Figures 13 to 14 shown, since the overall structure of the common bus bar includes a vertical bus bar 2000 and multiple horizontal bus bars 1000, and the number of horizontal bus bars 1000 is mainly three or four. To meet the requirements of different numbers of horizontal bus bars 1000, the tooling mechanism 210 includes a fifth frame body 211, a third carrier frame 213, and multiple second carrier frames 212. Among them, the multiple second carrier frames 212 are arranged parallel and spaced along the X direction on the fifth frame body 211, and each second carrier frame 212 is used to carry the horizontal bus bar 1000. The third carrier frame 213 is arranged along the second direction on the multiple fifth frame bodies 211, so that the tooling mechanism 210 can be applicable to the overall bus bars of different structures, improving the applicable range of the tooling mechanism 210. Exemplarily, the fifth frame body 211 is composed of three long profiles and four short profiles. Using profiles as the skeleton can greatly reduce the weight of the tooling mechanism 210.

[0131] Please continue to refer to Figures 14 to 16 , the third carrier frame 213 includes multiple first carrier blocks 2131 and multiple second carrier blocks 2132. The first carrier blocks 2131 and the second carrier blocks 2132 are arranged at intervals along the Y direction on the fifth frame body 211, and the lengths of the first carrier blocks 2131 and the second carrier blocks 2132 are different, so that users can select the applicable number of the first carrier blocks 2131 and the second carrier blocks 2132 according to the length of the vertical bus bar 2000, so as to improve the applicable range of the third carrier frame 213.

[0132] As Figures 14 to 15 shown, further, the first carrier block 2131 includes a second carrier body 21311 and two second limit members 21312. Among them, the second carrier body 21311 is arranged on the fifth frame body 211, and the two second limit members 21312 are arranged oppositely on the second carrier body 21311. The vertical bus bar 2000 can be arranged between the two second limit members 21312, so that the vertical bus bar 2000 extends along the Y direction, so as to improve the stability and safety of the vertical bus bar 2000 placed on the first carrier block 2131 and prevent it from falling.

[0133] Further, the first carrier block 2131 and the second carrier block 2132 are detachably connected to the fifth frame body 211 to meet the different size requirements of the operator.

[0134] As Figure 14 and Figure 15As shown, in order to improve the stability of the fixed vertical busbar 2000, a plurality of third adsorption holes 21313 are formed in the first bearing block 2131. The plurality of third adsorption holes 21313 are arranged along the extending direction of the first bearing block 2131. The third adsorption holes 21313 can be communicated with a vacuum generating device, so as to adsorb the vertical busbar 2000, improve the stability of the fixed vertical busbar 2000, and avoid falling.

[0135] It can be understood that the structural design of the second bearing block 2132 is the same as that of the first bearing block 2131.

[0136] A third limiting member 4122 is arranged on the second bearing frame 212, and the setting mode of the third limiting member 4122 is the same as that of the second limiting member 21312, which will not be elaborated here. The third limiting member 4122 can limit the horizontal busbar 1000 from both sides. Further, a plurality of fourth adsorption holes are formed in the second bearing frame 212. The plurality of fourth adsorption holes are arranged along the extending direction of the second bearing frame 212. The fourth adsorption holes can be communicated with a vacuum generating device, so as to adsorb the horizontal busbar 1000, improve the stability of the fixed horizontal busbar 1000, and avoid falling.

[0137] As Figure 14 and Figure 17 shown, as an alternative solution, the tooling mechanism 210 further includes a first pressing assembly 214. The first pressing assembly 214 is arranged on the fifth frame body 211. The first pressing assembly 214 is configured to press the vertical busbar 2000 to prevent the vertical busbar 2000 from moving, so as to improve the stability and safety of the vertical busbar 2000 placed on the first bearing block 2131 and avoid its falling.

[0138] As Figure 17 shown, specifically, the first pressing assembly 214 includes a first pressing driving member 2141 and a first pressing member 2142. Among them, the first pressing driving member 2141 is arranged on the fifth frame body 211. The first pressing member 2142 is hinged to the output end of the first pressing driving member 2141. The first pressing driving member 2141 can drive the first pressing member 2142 to press or release the vertical busbar 2000, so as to improve the stability and safety of the vertical busbar 2000 placed on the first bearing block 2131 and avoid its falling.

[0139] Further, along the Y direction, the fixing position of the second bearing frame 212 on the fifth frame body 211 is adjustable, so that the operator can set the position of the second bearing frame 212 on the fifth frame body 211 according to the distance between two adjacent horizontal busbars 1000, which is beneficial to improving the flexibility of the tooling mechanism 210 and expanding the application range of the tooling mechanism 210. At the same time, since the fifth frame body 211 is a profile structure framework, it is beneficial to improve the convenience of adjusting the second bearing frame 212.

[0140] Furthermore, the second carrier 212 is preferably made of composite stone material, which has high temperature resistance, is convenient for welding and fixing the horizontal bus bar 1000 and the vertical bus bar 2000, and will not deform at high temperatures, which is beneficial to improving the service life.

[0141] Please refer to Figure 18 , as an alternative solution, the tooling mechanism 210 further includes a second guiding component 215. The second guiding component 215 is disposed between the first frame 100 and the fifth frame 211, and the second guiding component 215 can provide guidance for the fifth frame 211 to move in the X direction, which is beneficial to improving the stability of the tooling mechanism 210 moving in the X direction.

[0142] Specifically, the second guiding component 215 includes a second guide rail and a second slider. The second guide rail is arranged along the second direction, and the second slider is slidably connected to the second guide rail. The second guide rail and the second slider are alternatively arranged on the fifth frame 211, and the other is arranged on the first frame 100. The structure of the second guiding component 215 is simple, which is convenient for the operator to assemble and maintain, and is beneficial to improving the stability of the tooling mechanism 210 moving in the X direction and avoiding jamming.

[0143] As Figure 18 shown, further, the tooling mechanism 210 further includes a support plate 216. The support plate 216 is disposed on both sides of the fifth frame 211 and is used to support the fifth frame 211 to improve the stability of the fifth frame 211.

[0144] After the overall welding of the bus bar is completed, it needs to be placed on the glass carrying the battery cells so as to enter the next process. For the convenience of description, the glass carrying the battery cells is named the battery module. As Figure 19 and Figure 20 shown, as an alternative solution, the bus bar welding equipment further includes a rectifying mechanism 500 and a third transfer mechanism 600. Among them, the rectifying mechanism 500 is used to carry the battery module and, by adjusting the position of the glass, rectify the battery cells on the glass to the designated position where the overall bus bar is placed. The third transfer mechanism 600 is used to transfer the overall bus bar to the rectifying mechanism 500. The rectifying mechanism 500 can improve the accuracy of the relative position between the battery module and the overall bus bar.

[0145] Now, in combination with Figure 19 the details of the third transfer mechanism 600 will be described.

[0146] As Figure 19As shown in the figure, the third transfer mechanism 600 includes a first grasping component 610 and a first driving member 620. The first grasping component 610 is used to grasp the entire bus bar. The first grasping component 610 is arranged at the output end of the first driving member 620. The first driving member 620 can drive the first grasping component 610 to move in a direction close to or away from the entire bus bar, so as to grasp the entire bus bar and transfer it.

[0147] Now in combination with Figure 20 the detailed structure of the alignment mechanism 500 will be described.

[0148] As Figure 20 shown in the figure, the alignment mechanism 500 includes a first alignment component 510 and a second alignment component 520. The first alignment component 510 can align the battery component in the X direction, and the second alignment component 520 can align the battery component in the Y direction, so as to position the battery component, so that the entire bus bar transferred by the third transfer mechanism 600 can be placed at a preset position, which is beneficial to improving the accuracy of the assembly process.

[0149] Please continue to refer to Figure 20 , specifically, the alignment mechanism 500 further includes a third frame body 530, and the third frame body 530 is used to carry the first alignment component 510 and the second alignment component 520. The first alignment component 510 includes a first alignment driving member 511 and a first alignment stop member 512. The first alignment driving member 511 is arranged on the third frame body 530, and the first alignment stop member 512 is arranged opposite to the first alignment driving member 511 in the X direction. The first alignment driving member 511 can drive the workpiece to move towards the first alignment stop member 512, so that the first alignment driving member 511 and the first alignment stop member 512 respectively restrict the positions of both ends of the battery component in the X direction, so as to make the relative position of the battery component and the entire bus bar a preset position.

[0150] Please continue to refer to Figure 20 , it can be understood that the second alignment component 520 includes a second alignment driving member 521 and a second alignment stop member 522. The detailed structure of the second alignment component 520 is the same as that of the first alignment component 510, and will not be elaborated here.

[0151] Furthermore, the alignment mechanism 500 further includes a camera detection member, which is used to detect the position of the battery chip to judge the existing position deviation of the battery chip, and then the alignment mechanism 500 realizes the position adjustment of the battery chip.

[0152] As Figures 1 to 20As shown above, in summary, the busbar welding equipment has three stations, and the tooling mechanism 210 moves among the three stations, and the horizontal busbar 1000 and the vertical busbar 2000 are placed and welded on the tooling mechanism 210. Among them, the first station is used to prepare three or four horizontal busbars 1000 (the specific number of horizontal busbars 1000 is determined according to the process), and the horizontal preparation mechanisms 310 are arranged on both sides of the busbar welding equipment and can prepare the horizontal busbars 1000 simultaneously. Then, the first transfer mechanism 320 first places two horizontal busbars 1000 on the transfer platform 330 at the same time. At this time, the horizontal preparation mechanisms 310 on both sides continue to prepare the latter two busbars, and finally the first transfer mechanism 320 places the horizontal busbars 1000 on the tooling mechanism 210.

[0153] The second station is used to prepare and bend the vertical busbar 2000 and weld and fix the vertical busbar 2000 and the horizontal busbar 1000. Specifically, since the vertical busbar 2000 includes multiple segments, the second station includes two vertical preparation mechanisms 410. The two vertical preparation mechanisms 410 simultaneously prepare the vertical busbar 2000 in segments from both ends, and the second transfer mechanism 420 places the vertical busbar 2000 on the tooling mechanism 210 and welds and fixes the horizontal busbar 1000 and the vertical busbar 2000 at the same time.

[0154] The third station is the third transfer mechanism 600 and the alignment mechanism 500. The alignment mechanism 500 is used to carry the battery assembly (i.e., the glass and the battery chip), and the third transfer mechanism 600 transfers the whole busbar to the battery assembly. Since there are position requirements for the whole welded busbar and the battery chip placed on the glass, the alignment mechanism 500 is required to adjust the position of the battery chip placed on the glass to make it located at the preset position, and then the position of the battery chip is detected by the camera detection part, and the position of the battery chip is adjusted by the alignment mechanism 500.
