Description

Technical Field

[0001] The present application relates to the field of photovoltaic cell module production equipment, and more specifically to a bus bar preparation device and a bus bar welding device. Background Art

[0002] Solar cell modules can convert solar energy into electrical energy and are currently being gradually popularized and applied. In the process of producing solar cell modules, there is a process of welding bus bars, which requires welding the bus bars to the extended welding tapes at both ends and the middle of the cell string module. Among them, in order to facilitate the subsequent installation of the junction box, the bus bar welded to the extended welding tape in the middle of the cell string module is a bent bus bar with a bent end, and the bent end of the bus bar is used to insert into the junction box and be welded to the junction box. The bus bars welded to the extended welding tapes at both ends of the cell string module are straight bus bars without bending.

[0003] During the bus bar welding process, it is necessary to prepare the bent bus bars and straight bus bars required for welding, and supply the bent bus bars and straight bus bars to the corresponding welding stations. The existing bus bar preparation device includes a first carrier, a second carrier, and a third carrier arranged in sequence along the horizontal direction, a first straight bus bar preparation mechanism and a bent bus bar preparation mechanism arranged on one side of the three carriers, a second straight bus bar preparation mechanism arranged on the other side of the three carriers, and a first handling mechanism and a second handling mechanism. Among them, the first handling mechanism is used to transport the straight bus bars prepared by the first straight bus bar preparation mechanism to the first carrier, and to transport the bent bus bars prepared by the bent bus bar preparation mechanism to the second carrier. The second handling mechanism is used to transport the straight bus bars prepared by the second straight bus bar preparation mechanism to the third carrier. Among them, the straight bus bars transported to the first carrier are finally welded to the extended welding tape at the first end of the cell string module, the bent bus bars transported to the second carrier are finally welded to the extended welding tape in the middle of the cell string module, and the straight bus bars transported to the third carrier are finally welded to the extended welding tape at the second end of the cell string module.

[0004] For the straight bus bars to be welded to both ends of the cell string module in the existing bus bar preparation device, it is necessary to set up a straight bus bar preparation mechanism on each side of the welding station. Since two straight bus bar preparation mechanisms need to be set up, and each straight bus bar preparation mechanism at least includes components such as a bus bar unwinding assembly, a pressing assembly, a cutting assembly, a traction assembly, and a preparation table, the equipment structure of the bus bar preparation device is relatively complex, the equipment maintenance workload is large, and the equipment cost is relatively high. Summary of the Utility Model

[0005] In order to solve the above at least one technical problem, the present application provides a bus bar preparation device, which adopts the following technical solutions:

[0006] A bus bar preparation device includes a first preparation mechanism, a second preparation mechanism, a first carrying mechanism, a second carrying mechanism, a third carrying mechanism, a first handling mechanism, a second handling mechanism and a transfer mechanism, wherein:

[0007] The first carrying mechanism, the second carrying mechanism and the third carrying mechanism are arranged at intervals in sequence along a first horizontal direction and can move along the first horizontal direction respectively. Among them: the first carrying mechanism includes a first carrying platform, the second carrying mechanism includes a second carrying platform and a first buffer platform, and the third carrying mechanism includes a third carrying platform and a second buffer platform;

[0008] The first preparation mechanism is arranged on the side of the first carrying mechanism. The first preparation mechanism is configured to prepare a bent bus bar, and the first handling mechanism is configured to carry the bent bus bar prepared by the first preparation mechanism to the second carrying platform;

[0009] The second preparation mechanism is arranged on the side of the third carrying mechanism. The second preparation mechanism is configured to prepare a straight bus bar, and the second handling mechanism is configured to carry the straight bus bar prepared by the second preparation mechanism to the third carrying platform or the second buffer platform;

[0010] The transfer mechanism is arranged between the third carrying mechanism and the second carrying mechanism. The transfer mechanism is configured to pick up the straight bus bar cached on the second buffer platform and carry the picked-up straight bus bar to the first buffer platform;

[0011] The first handling mechanism is further configured to pick up the straight bus bar cached on the first buffer platform and carry the picked-up straight bus bar to the first carrying platform.

[0012] For the bus bar preparation device provided by the present application, only one straight bus bar preparation mechanism needs to be set. Through the cooperation of the first handling mechanism, the second handling mechanism, the first buffer platform, the second buffer platform and the transfer mechanism, the straight bus bars can be supplied to the first carrying platform and the third carrying platform respectively to meet the welding requirements of the straight bus bars at both ends of the battery string assembly. Compared with the existing bus bar preparation device, the simple-structured first buffer platform, second buffer platform and transfer mechanism replace the complex-structured straight bus bar preparation mechanism. While ensuring the bus bar preparation efficiency, the structural complexity and cost of the bus bar preparation device of the present application are reduced, and at the same time, the daily maintenance work of the straight bus bar preparation mechanism on one side is also saved.

[0013] In some embodiments, the first handling mechanism includes a first driving module and at least one first adsorption component, wherein: the first adsorption component is connected to the driving end of the first driving module, and the first driving module is configured to drive the first adsorption component to translate and lift; the first adsorption component is configured to, under the drive of the first driving module, suck the bent busbar from the first preparation mechanism, transport the sucked bent busbar to the second carrying platform, and suck the straight busbar from the first buffer platform and transport the sucked straight busbar to the first carrying platform.

[0014] A first handling mechanism with a simple structure is provided. It drives the first adsorption component to translate and lift through the first driving module, so as to drive the first adsorption component to suck the bent busbar from the first preparation mechanism, transport the sucked bent busbar to the second carrying platform, and suck the straight busbar from the first buffer platform and transport the sucked straight busbar to the first carrying platform.

[0015] In some embodiments, the first handling mechanism includes two first adsorption components connected side by side to the driving end of the first driving module. When one of the first adsorption components releases the bent busbar sucked from the first preparation mechanism to the second carrying platform, the other first adsorption component sucks the straight busbar from the first buffer platform.

[0016] By providing two first adsorption components, the first handling mechanism sucks the straight busbar from the first buffer platform while transporting the bent busbar on the first preparation mechanism to the second carrying platform, thereby improving the handling efficiency of the busbar by the first handling mechanism.

[0017] In some embodiments, the second handling mechanism includes a second driving module and at least one second adsorption component, wherein: the second adsorption component is connected to the driving end of the second driving module, and the second driving module is configured to drive the second adsorption component to translate and lift; the second adsorption component is configured to, under the drive of the second driving module, suck the straight busbar from the second preparation mechanism and transport the sucked straight busbar to the third carrying platform or the second buffer platform.

[0018] A second handling mechanism with a simple structure is provided. It drives the second adsorption component to translate and lift through the second driving module, so as to drive the second adsorption component to suck the straight busbar from the second preparation mechanism and transport the sucked straight busbar to the third carrying platform or the second buffer platform.

[0019] In some embodiments, the second handling mechanism includes two second adsorption components connected side by side to the driving end of the second driving module. The two second adsorption components are configured to respectively suck a straight busbar from the second preparation mechanism and respectively transport the sucked straight busbars to the third carrying platform and the second buffer platform.

[0020] By providing two second adsorption components, after the second handling mechanism sucks two sets of flat busbars from the second preparation mechanism, it can then move to separately transport the two sets of flat busbars to the third carrier table and the second buffer table, thereby improving the handling efficiency of the second handling mechanism for the busbars.

[0021] In some embodiments, first adsorption holes and positioning pin assemblies are provided on the table surfaces of the first buffer table and the second buffer table. Among them, the positioning pin assembly includes a first positioning pin and a second positioning pin arranged at intervals, and the distance between the first positioning pin and the second positioning pin matches the width of the flat busbar.

[0022] The first adsorption holes can adsorb and fix the flat busbars cached on the first buffer table or the second buffer table to the first buffer table or the second buffer table. The first positioning pin and the second positioning pin can then limit the flat busbars cached on the first buffer table or the second buffer table from both sides, preventing the flat busbars from slipping or shifting in position.

[0023] In some embodiments, second adsorption holes are provided on the table surfaces of the first carrier table, the second carrier table, and the third carrier table.

[0024] By providing second adsorption holes on the table surfaces of the first carrier table, the second carrier table, and the third carrier table, the first carrier table, the second carrier table, and the third carrier table can all adsorb and fix the bent busbars or flat busbars transported onto them, ensuring the welding accuracy of the busbars.

[0025] In some embodiments, the busbar preparation device further includes a slide rail arranged along the first horizontal direction; the first carrier mechanism, the second carrier mechanism, and the third carrier mechanism are all slidably connected to the slide rail and can all slide along the slide rail to adjust their positions in the first horizontal direction; alternatively, the first carrier mechanism, the second carrier mechanism, the third carrier mechanism, and the transfer mechanism are all slidably connected to the slide rail and can all slide along the slide rail to adjust their positions in the first horizontal direction.

[0026] By slidably connecting the first carrier mechanism, the second carrier mechanism, and the third carrier mechanism to the same slide rail, the structure is simple and compact, and the movement guidance of the first carrier mechanism, the second carrier mechanism, and the third carrier mechanism in the first horizontal direction is realized. Finally, it is ensured that the flat busbars transported to the first carrier mechanism and the third carrier mechanism are respectively located below the extended welding tapes at the first end and the second end of the battery string assembly, and the bent busbar on the second carrier mechanism is located below the extended welding tape in the middle of the battery string assembly. By slidably connecting the transfer mechanism to the slide rail, the transfer mechanism can stably move between the second preparation mechanism and the second carrier mechanism, and the structure is also more compact.

[0027] In some embodiments, the first carrier mechanism further includes a first lifting drive module for driving the first carrier platform to lift, the second carrier mechanism further includes a second lifting drive module for driving the second carrier platform to lift, and the third carrier mechanism further includes a third lifting drive module for driving the third carrier platform to lift.

[0028] The first lifting drive module drives the first carrier platform to rise, so that the straight busbar located on the first carrier platform can abut against the extended welding tape at the first end of the battery string assembly, and finally ensures that the straight busbar on the first carrier platform is welded to the extended welding tape at the first end of the battery string assembly. The second lifting drive module drives the second carrier platform to rise, so that the bent busbar located on the second carrier platform abuts against the extended welding tape in the middle of the battery string assembly, and finally ensures that the bent busbar on the second carrier platform is welded to the extended welding tape in the middle of the battery string assembly. The third lifting drive module drives the third carrier platform to rise, so that the straight busbar located on the third carrier platform abuts against the extended welding tape at the second end of the battery string assembly, and finally ensures that the straight busbar on the third carrier platform is welded to the extended welding tape at the second end of the battery string assembly.

[0029] In some embodiments, the first buffer table and the second buffer table are arranged adjacent to each other, and the transfer mechanism is arranged between the first buffer table and the second buffer table.

[0030] The first buffer table and the second buffer table are arranged adjacent to each other, so that the transfer mechanism can pick up the straight busbar from the second buffer table and transport the picked-up straight busbar to the first buffer table while the busbars on the three carrier platforms are being welded. The transfer of the transfer mechanism will not interfere with the welding, thus ensuring the working rhythm and improving the welding efficiency of the busbar.

[0031] The present application also provides a busbar welding device, which includes the busbar preparation device, the welding pickup device and the welding device described in any one of the above, wherein:

[0032] The welding pickup device is configured to pick up the battery string assembly with the busbar to be welded and transport it above the busbar preparation device. The first carrier platform is used to transport the straight busbar carried thereon to the lower part of the extended welding tape at the first end of the battery string assembly. The second carrier platform is used to transport the bent busbar carried thereon to the lower part of the extended welding tape in the middle of the battery string assembly. The third carrier platform is used to transport the straight busbar carried thereon to the lower part of the extended welding tape at the second end of the battery string assembly;

[0033] The welding device is configured to weld the straight busbar located on the first carrier platform to the extended welding tape at the first end of the battery string assembly, weld the bent busbar located on the second carrier platform to the extended welding tape in the middle of the battery string assembly, and weld the straight busbar located on the third carrier platform to the extended welding tape at the second end of the battery string assembly.

[0034] The bus bar preparation device realizes the preparation of the bus bar, as well as the carrying and moving of the bus bar and the welding support. The welding pickup device moves the battery string assembly of the bus bar to be welded above the bus bar preparation device, and the welding device realizes welding the bus bar to the extended welding strip of the battery string assembly. When the welding device welds the bus bar, the bus bar preparation device can synchronously carry out the preparation and handling of the bus bar, improving efficiency.

[0035] In some embodiments, the welding device includes a first welding mechanism, a second welding mechanism, and a third welding mechanism, where: the first welding mechanism is arranged above the first carrier and is configured to weld the straight bus bar located on the first carrier to the extended welding strip at the first end of the battery string assembly; the second welding mechanism is arranged above the second carrier and is configured to weld the bent bus bar located on the second carrier to the extended welding strip in the middle of the battery string assembly; the third welding mechanism is arranged above the third carrier and is configured to weld the straight bus bar located on the third carrier to the extended welding strip at the second end of the battery string assembly.

[0036] By setting the welding device to include a first welding mechanism, a second welding mechanism, and a third welding mechanism, the welding device can synchronously weld the bus bar to the extended welding strips at the first end and the second end of the battery string assembly, as well as the extended welding strip in the middle of the battery string assembly, improving the welding efficiency of the bus bar.

[0037] In some embodiments, the welding device includes a first heating mechanism, a second heating mechanism, and a third heating mechanism. Among them, the first heating mechanism is arranged inside the first carrier, the second heating mechanism is arranged inside the second carrier, and the third heating mechanism is arranged inside the third carrier; the bus bar welding equipment further includes a pressing device, and the pressing device includes a first pressing mechanism arranged above the first carrier, a second pressing mechanism arranged above the second carrier, and a third pressing mechanism arranged above the third carrier; the first pressing mechanism is configured to press the extended welding strip at the first end of the battery string assembly onto the straight bus bar on the first carrier, and the first heating mechanism is configured to heat the straight bus bar on the first carrier to weld the straight bus bar to the extended welding strip at the first end of the battery string assembly; the second pressing mechanism is configured to press the extended welding strip in the middle of the battery string assembly onto the bent bus bar on the second carrier, and the second heating mechanism is configured to heat the bent bus bar on the second carrier to weld the bent bus bar to the extended welding strip in the middle of the battery string assembly; the third pressing mechanism is configured to press the extended welding strip at the second end of the battery string assembly onto the straight bus bar on the third carrier, and the third heating mechanism is configured to heat the straight bus bar on the third carrier to weld the straight bus bar to the extended welding strip at the second end of the battery string assembly.

[0038] By setting the welding device to include a first heating mechanism, a second heating mechanism, and a third heating mechanism, the welding device can synchronously weld the bus bar to the extended welding tapes at the first end and the second end of the battery string assembly, as well as the extended welding tape in the middle of the battery string assembly, improving the welding efficiency of the bus bar.

[0056] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] As Figures 1 to 5 shown, the bus bar preparation device in the embodiment of the present application includes a first preparation mechanism 1, a second preparation mechanism 2, a first carrying mechanism 3, a second carrying mechanism 4, a third carrying mechanism 5, a first handling mechanism 6, a second handling mechanism 7, and a transfer mechanism 8, where:

[0058] The first carrying mechanism 3, the second carrying mechanism 4, and the third carrying mechanism 5 are sequentially arranged at intervals along a first horizontal direction (for example, the X-axis direction) and can move respectively along the first horizontal direction. Among them: The first carrying mechanism 3 includes a first carrying platform 31, the second carrying mechanism 4 includes a second carrying platform 41 and a first buffer platform 42, and the third carrying mechanism 5 includes a third carrying platform 51 and a second buffer platform 52.

[0059] The first preparation mechanism 1 is arranged on the side of the first carrying mechanism 3, and the first preparation mechanism 1 is configured to prepare a bent bus bar. The first handling mechanism 6 is configured to handle the bent bus bar prepared by the first preparation mechanism 1 to the second carrying platform 41.

[0060] The second preparation mechanism 2 is arranged on the side of the third carrying mechanism 5, and the second preparation mechanism 2 is configured to prepare a straight bus bar. The second handling mechanism 7 is configured to handle the straight bus bar prepared by the second preparation mechanism 2 to the third carrying platform 51 or the second buffer platform 52.

[0061] The transfer mechanism 8 is arranged between the third carrying mechanism 5 and the second carrying mechanism 4. The transfer mechanism 8 is configured to pick up the straight bus bar buffered on the second buffer platform 52 and handle the picked-up straight bus bar to the first buffer platform 42.

[0062] The first handling mechanism 6 is further configured to pick up the straight bus bar buffered on the first buffer platform 42 and handle the picked-up straight bus bar to the first carrying platform 31.

[0063] Among them, the first preparation mechanism 1 can adopt any one of the existing bent bus bar preparation mechanisms in the prior art, and the second preparation mechanism 2 can adopt any one of the existing straight bus bar preparation mechanisms in the prior art.

[0064] The optional working process of the bus bar preparation device in the embodiment of the present application is as follows:

[0065] The first preparation mechanism 1 and the second preparation mechanism 2 respectively prepare a bent bus bar and a straight bus bar.

[0066] The first handling mechanism 6 transports the bent busbars prepared by the first preparation mechanism 1 to the second carrier 41. Meanwhile, the second handling mechanism 7 transports the straight busbars prepared by the second preparation mechanism 2 to the third carrier 51 and the second buffer 52. Among them, the second handling mechanism 7 can pick up two groups of straight busbars from the second preparation mechanism 2 in two times, and transport the straight busbars to the third carrier 51 or the second buffer 52 immediately after picking up one group of straight busbars each time. The second handling mechanism 7 can also pick up two groups of straight busbars from the second preparation mechanism 2 in two times, and transport the two groups of straight busbars to the third carrier 51 and the second buffer 52 simultaneously after the two pick-ups are completed.

[0067] The transfer mechanism 8 picks up the straight busbars cached on the second buffer 52 and transports the picked straight busbars to the first buffer 42. Subsequently, the first handling mechanism 6 picks up the straight busbars from the first buffer 42 and transports the picked straight busbars to the first carrier 31. In addition, after the second buffer 52 is emptied, the second handling mechanism 7 picks up another group of straight busbars from the second preparation mechanism 2 and caches them on the second buffer 52.

[0068] At this point, the first carrier 31, the second carrier 41, and the third carrier 51 are all loaded with the busbars required for the first round of busbar welding, and the straight busbars required for the second round of busbar welding are cached on the second buffer 52.

[0069] Perform the first round of busbar welding. Specifically, after the battery string assembly with the busbars to be welded is moved above the busbar preparation device. According to the positions of the extended welding tapes at the first end, the middle, and the second end of the battery string assembly, control the first carrier mechanism 3, the second carrier mechanism 4, and the third carrier mechanism 5 to translate in the first horizontal direction, so that the first carrier 31, the second carrier 41, and the third carrier 51 are respectively located at the first welding position, the second welding position, and the third welding position, ensuring that the straight busbars on the first carrier 31 are located below the extended welding tape at the first end of the battery string assembly, the bent busbars on the second carrier 41 are located below the extended welding tape in the middle of the battery string assembly, and the straight busbars on the third carrier 51 are located below the extended welding tape at the second end of the battery string assembly. In this way, it can be ensured that the busbars can be welded to the corresponding extended welding tapes. After the busbar welding is completed, control the first carrier mechanism 3, the second carrier mechanism 4, and the third carrier mechanism 5 to move back to their original positions.

[0070] While the first round of bus bar welding is being carried out, the transfer mechanism 8 transports the straight bus bars cached on the second buffer table 52 to the first buffer table 42 to prepare for the second round of bus bar welding. Of course, the transfer mechanism 8 can also transport the straight bus bars cached on the second buffer table 52 to the first buffer table 42 before the first round of bus bar welding is carried out.

[0071] After the first round of bus bar welding is completed, since there are already straight bus bars cached on the first buffer table 42, therefore, before the second round of bus bar welding is carried out, after the first handling mechanism 6 transports the bent bus bars prepared by the first preparation mechanism 1 to the second carrier table 41, it can immediately pick up the straight bus bars cached in advance from the first buffer table 42 and transport the straight bus bars to the first carrier table 31, so as to ensure the working rhythm. At the same time, the second handling mechanism 7 transports the straight bus bars prepared by the second preparation mechanism 2 to the third carrier table 51 and the second buffer table 52.

[0072] At this point, the first carrier table 31, the second carrier table 41 and the third carrier table 51 are all loaded with the bus bars required for the second round of bus bar welding, and the straight bus bars required for the third round of bus bar welding are cached on the second buffer table 52.

[0073] The second round of bus bar welding is carried out, and the specific process is the same as that of the first round of bus bar welding, which will not be elaborated here. Similarly, during the process of the second round of bus bar welding, or before the second round of bus bar welding is carried out, the transfer mechanism 8 transports the straight bus bars cached on the second buffer table 52 to the first buffer table 42 to prepare for the third round of bus bar welding.

[0074] It can be seen that the bus bar preparation device of the embodiment of the present application only needs to be provided with one straight bus bar preparation mechanism (i.e., the second preparation mechanism 2). Through the cooperation of the first handling mechanism 6, the second handling mechanism 7, the first buffer table 42, the second buffer table 52 and the transfer mechanism 8, it can supply straight bus bars to the first carrier table 31 and the third carrier table 51 respectively, meeting the welding requirements of the straight bus bars at both ends of the battery string assembly.

[0075] Compared with the existing bus bar preparation device, the simple-structured first buffer table 42, second buffer table 52 and transfer mechanism 8 are used to replace the complex-structured straight bus bar preparation mechanism. While ensuring the bus bar preparation efficiency, the structural complexity and cost of the bus bar preparation device of the embodiment of the present application are reduced, and at the same time, the daily maintenance work of the straight bus bar preparation mechanism on one side is also eliminated.

[0076] Optionally, the first carrier mechanism 3 is configured to move between the first preparation mechanism 1 and the first welding position, the second carrier mechanism 4 is configured to move between the first preparation mechanism 1 and the second welding position, and the third carrier mechanism 5 is configured to move between the second preparation mechanism 2 and the third welding position. The movement paths required for all three are relatively short, thus ensuring the welding efficiency.

[0077] In addition, before or during the implementation of the current round of bus bar welding, the flat bus bars required for the next round of bus bar welding have been cached on the first buffer table 42. Therefore, before the implementation of the next round of bus bar welding, the first handling mechanism 6 can directly pick up the pre-cached flat bus bars from the first buffer table 42 without waiting for the transfer mechanism 8 to cache the flat bus bars on the first buffer table 42, thus ensuring the working rhythm.

[0078] As Figure 6 shown, optionally, the first handling mechanism 6 includes a first driving module 61 and at least one first adsorption component 62, wherein: the first adsorption component 62 is connected to the driving end of the first driving module 61, and the first driving module 61 is configured to drive the first adsorption component 62 to translate and lift. The first adsorption component 62 is configured to suck the bent bus bar from the first preparation mechanism 1 and transport the sucked bent bus bar to the second carrier table 41 under the drive of the first driving module 61, and suck the flat bus bar from the first buffer table 42 and transport the sucked flat bus bar to the first carrier table 31.

[0079] The first driving module 61 can adopt various existing driving modules capable of driving the first adsorption component 62 to translate and lift. For example, the first driving module 61 includes a translation driving part and a lifting driving part. Among them, the lifting driving part is connected to the driving end of the translation driving part, and the first adsorption component 62 is connected to the driving end of the lifting driving part. The translation driving part is used to drive the first adsorption component 62 to translate, and the lifting driving part is used to drive the first adsorption component 62 to lift. The first adsorption component 62 can be, for example, a plurality of suction cups arranged at intervals, and the plurality of suction cups cooperate to suck the bent bus bar or the flat bus bar.

[0080] Of course, other structures of handling mechanisms capable of handling bus bars can also be used as the first handling mechanism 6, such as a suction component driven by a robot arm.

[0081] Optionally, the first handling mechanism 6 includes two first adsorption components 62 connected side by side to the driving end of the first driving module 61. The handling process of the first handling mechanism 6 is as follows: First, the first driving module 61 drives the two first adsorption components 62 above the first preparation mechanism 1, and one of the first adsorption components 62 sucks a bent bus bar from the first preparation mechanism 1. Subsequently, the first driving module 61 drives the two first adsorption components 62 above the second carrying mechanism 4. When one of the first adsorption components 62 releases the bent bus bar onto the second carrying platform 41, the other first adsorption component 62 can simultaneously suck a straight bus bar from the first buffer platform 42. Finally, the first driving module 61 drives the two first adsorption components 62 above the first carrying mechanism 3, and the other first adsorption component 62 releases the straight bus bar onto the first carrying platform 31.

[0082] It can be seen that by setting two first adsorption components 62, while the first handling mechanism 6 transports the bent bus bar on the first preparation mechanism 1 to the second carrying platform 41, it can suck the straight bus bar from the first buffer platform 42, thereby improving the handling efficiency of the first handling mechanism 6 for the bus bar.

[0083] Of course, in order to save equipment costs, the first handling mechanism 6 can also include only one first adsorption component 62. In this case, after the first handling mechanism 6 transports the bent bus bar on the first preparation mechanism 1 to the second carrying platform 41, it sucks the straight bus bar from the first buffer platform 42 and transports the straight bus bar to the first carrying platform 31.

[0084] As Figure 7 shown, optionally, the second handling mechanism 7 includes a second driving module 71 and at least one second adsorption component 72, where: The second adsorption component 72 is connected to the driving end of the second driving module 71, and the second driving module 71 is configured to drive the second adsorption component 72 to translate and lift. The second adsorption component 72 is configured to suck a straight bus bar from the second preparation mechanism 2 under the drive of the second driving module 71 and transport the sucked straight bus bar to the third carrying platform 51 or the second buffer platform 52.

[0085] The second driving module 71 can adopt various existing driving modules capable of driving the second adsorption component 72 to translate and lift. For example, the second driving module 71 includes a translation driving part and a lifting driving part. Among them, the lifting driving part is connected to the driving end of the translation driving part, and the second adsorption component 72 is connected to the driving end of the lifting driving part. The translation driving part is used to drive the second adsorption component 72 to translate, and the lifting driving part is used to drive the second adsorption component 72 to lift. The second adsorption component 72 can include, for example, a plurality of suction cups arranged at intervals, and the plurality of suction cups cooperate to suck the straight bus bar.

[0086] Of course, a handling mechanism with other structures that can handle the busbars can also be used as the second handling mechanism 7, such as a suction component driven by a robotic arm, etc.

[0087] Optionally, the second handling mechanism 7 includes two second adsorption components 72 connected side by side to the driving end of the second driving module 71. The two second adsorption components 72 are configured to respectively suck a straight busbar from the second preparation mechanism 2 and respectively transport the sucked straight busbars to the third carrier 51 and the second buffer 52.

[0088] By providing two second adsorption components 72, the second handling mechanism 7 can suck two groups of straight busbars from the second preparation mechanism 3 and then transport the two groups of straight busbars to the third carrier 51 and the second buffer 52 respectively, thereby improving the handling efficiency of the second handling mechanism 7 for the busbars. Among them, the number of straight busbars in each group is determined according to the number of busbars to be welded in the current round, which can be one, or two or more.

[0089] Of course, in order to save equipment costs, the second handling mechanism 7 can also include only one second adsorption component 72. In this case, the second handling mechanism 7 sucks a group of straight busbars from the second preparation mechanism 3 in two separate times and transports the sucked straight busbars to the third carrier 51 and the second buffer 52 respectively.

[0090] Optionally, first adsorption holes and positioning pin assemblies are provided on the surfaces of the first buffer 42 and the second buffer 52. Among them, the positioning pin assembly includes a first positioning pin and a second positioning pin arranged at intervals, and the distance between the first positioning pin and the second positioning pin matches the width of the straight busbar. Among them, the first adsorption holes can adsorb and fix the straight busbars cached on the first buffer 42 or the second buffer 52 on the first buffer 42 or the second buffer 52, and the first positioning pin and the second positioning pin can limit the straight busbars cached on the first buffer 42 or the second buffer 52 from both sides to prevent the straight busbars from slipping or shifting in position.

[0091] Optionally, second adsorption holes are provided on the surfaces of the first carrier 31, the second carrier 41, and the third carrier 51. The first carrier 31, the second carrier 41, and the third carrier 51 can all adsorb and fix the bent busbars or straight busbars transported onto them through the second adsorption holes on them.

[0092] Such as Figures 1 to 5As shown, optionally, the bus bar preparation device in the embodiments of the present application further includes a slide rail 9 arranged along the first horizontal direction. The first carrying mechanism 3, the second carrying mechanism 4, and the third carrying mechanism 5 are all slidably connected to the slide rail 9 and can all slide along the slide rail 9 to implement position adjustment in the first horizontal direction. Before welding the bus bar, by controlling the first carrying mechanism 3, the second carrying mechanism 4, and the third carrying mechanism 5 to slide along the slide rail 9, it can be ensured that the straight bus bars carried on the first carrying mechanism 3 and the third carrying mechanism 5 are respectively located below the extended welding tapes at the first end and the second end of the battery string assembly, and the bent bus bar carried on the second carrying mechanism 4 is located below the extended welding tape in the middle of the battery string assembly. In addition, since the first carrying mechanism 3, the second carrying mechanism 4, and the third carrying mechanism 5 all slide along the slide rail 9, it can be ensured that the first carrying mechanism 3, the second carrying mechanism 4, and the third carrying mechanism 5 are aligned in the first horizontal direction.

[0093] Optionally, the first carrying mechanism 3, the second carrying mechanism 4, and the third carrying mechanism 5 are all driven by independent driving mechanisms to achieve independent sliding on the slide rail 9.

[0094] Optionally, the transfer mechanism 8 is also slidably connected to the slide rail 9. In this way, the transfer mechanism 8 can slide stably along the slide rail 9 to implement reciprocating movement between the second preparation mechanism 2 and the second carrying mechanism 3. Optionally, as Figure 1 shown, the transfer mechanism 8 includes a driving part (not shown in the figure), a base 81, a frame 82, and a plurality of suction cups 83 arranged on the frame 82. The base 81 is slidably connected to the slide rail 9 and is connected to the driving end of the driving part. When the driving part drives the base to move in place towards the third carrying mechanism 5, the second buffer table 52 enters into the frame 82, and a plurality of suction cups 83 on the frame 82 suck the straight bus bars on the second buffer table 52. When the driving part drives the base to move in place towards the second carrying mechanism 4, the first buffer table 42 enters into the frame 82, and a plurality of suction cups 83 on the frame 82 release the sucked straight bus bars onto the first buffer table 42.

[0095] Optionally, the first carrying mechanism 3 further includes a first lifting driving module for driving the first carrying table 31 to lift. The second carrying mechanism 4 further includes a second lifting driving module for driving the second carrying table 41 to lift. The third carrying mechanism 5 further includes a third lifting driving module for driving the third carrying table 51 to lift. The first lifting driving module, the second lifting driving module, and the third lifting driving module can all adopt various existing linear driving modules, such as a cylinder driving module, an electric cylinder driving module, etc.

[0096] The battery string assembly with the bus bar to be welded is moved above the bus bar preparation device, and the straight bus bars on the first carrier mechanism 3 and the third carrier mechanism 5 are respectively located below the extended welding tapes at the first end and the second end of the battery string assembly, and the bent bus bar on the second carrier mechanism 4 is located below the extended welding tape in the middle of the battery string assembly. By driving the first carrier platform 31 to rise through the first lifting drive module, the straight bus bar located on the first carrier platform 31 can be made to abut against the extended welding tape at the first end of the battery string assembly. By driving the second carrier platform 41 to rise through the second lifting drive module, the bent bus bar located on the second carrier platform 41 can be made to abut against the extended welding tape in the middle of the battery string assembly. By driving the third carrier platform 51 to rise through the third lifting drive module, the straight bus bar located on the third carrier platform 51 can be made to abut against the extended welding tape at the second end of the battery string assembly. In this way, it can be ensured that the welding mechanism can weld the bus bar to the corresponding extended welding tape.

[0097] As Figure 1 shown, optionally, the first buffer table 42 and the second buffer table 52 are arranged adjacent to each other, and the transfer mechanism 8 is arranged between the first buffer table 42 and the second buffer table 52.

[0098] With this arrangement, while the transfer mechanism 8 is welding the bus bars on the three carrier platforms, it can pick up the straight bus bars cached on the second buffer table 52 for the next round of welding and transport the picked-up straight bus bars to the first buffer table 42, and the transfer of the transfer mechanism 8 will not interfere with the welding of the bus bars on the second carrier platform 41 and the third carrier platform 51. After welding is completed, the first handling mechanism 6 can then transport the straight bus bars on the first buffer table 42 to the first carrier platform 31 to ensure the timely supply of the bus bars on the first carrier platform 31, thereby ensuring the working rhythm and improving the welding efficiency of the bus bars.

[0099] In the embodiment of the present application, a bus bar welding device is further provided, which includes the bus bar preparation device, the welding pickup device and the welding device provided in any of the above embodiments, wherein:

[0100] The welding pickup device is configured to pick up the battery string assembly with the bus bar to be welded and transport it above the bus bar preparation device. The first carrier platform 31 is used to transport the straight bus bar carried thereon to below the extended welding tape at the first end of the battery string assembly. The second carrier platform 41 is used to transport the bent bus bar carried thereon to below the extended welding tape in the middle of the battery string assembly. The third carrier platform 51 is used to transport the straight bus bar carried thereon to below the extended welding tape at the second end of the battery string assembly.

[0101] The welding device is configured to weld the flat bus bar located on the first carrier 31 to the extended solder tape at the first end of the battery string assembly, weld the bent bus bar located on the second carrier 41 to the extended solder tape in the middle of the battery string assembly, and weld the flat bus bar located on the third carrier 51 to the extended solder tape at the second end of the battery string assembly.

[0102] It can be seen that the bus bar preparation device realizes the preparation of the bus bar, as well as the carrying, moving and welding support of the bus bar. The welding pickup device realizes moving the battery string assembly with the bus bar to be welded above the bus bar preparation device. The welding device realizes welding the bus bar to the extended solder tape of the battery string assembly. When the welding device welds the bus bar, the bus bar preparation device can synchronously carry out the preparation and handling of the bus bar, improving the welding efficiency of the bus bar.

[0103] In an optional embodiment, the welding device includes a first welding mechanism, a second welding mechanism and a third welding mechanism, where: The first welding mechanism is arranged above the first carrier 31 and is configured to weld the flat bus bar located on the first carrier 31 to the extended solder tape at the first end of the battery string assembly. The second welding mechanism is arranged above the second carrier 41 and is configured to weld the bent bus bar located on the second carrier 41 to the extended solder tape in the middle of the battery string assembly. The third welding mechanism is arranged above the third carrier and is configured to weld the flat bus bar located on the third carrier 51 to the extended solder tape at the second end of the battery string assembly.

[0104] By setting the welding device to include a first welding mechanism, a second welding mechanism and a third welding mechanism, the welding device can synchronously weld the bus bar to the extended solder tapes at the first end and the second end of the battery string assembly, as well as the extended solder tape in the middle of the battery string assembly, improving the welding efficiency of the bus bar.

[0105] The first welding mechanism, the second welding mechanism and the third welding mechanism can adopt various existing structures of bus bar welding mechanisms. For example, taking the first welding mechanism as an example, a liftable hot pressing welding head is adopted. During welding, the hot pressing welding head descends to press the extended solder tape at the first end of the battery string assembly downward onto the flat bus bar located on the first carrier 31 and implement heating, so that the flat bus bar is welded to the extended solder tape; or, taking the first welding mechanism as an example, it includes a pressing part and a laser welding head, where the pressing part is used to press the extended solder tape at the first end of the battery string assembly downward onto the flat bus bar located on the first carrier 31, and the laser welding head is used to perform laser welding on the pressed extended solder tape and the flat bus bar, so that the flat bus bar is welded to the extended solder tape.

[0106] In another alternative embodiment, the welding device includes a first heating mechanism, a second heating mechanism, and a third heating mechanism. Among them, the first heating mechanism is disposed within the first carrier 31. The second heating mechanism is disposed within the second carrier 41. The third heating mechanism is disposed within the third carrier 51. The bus bar welding equipment further includes a pressing device, and the pressing device includes a first pressing mechanism disposed above the first carrier 31, a second pressing mechanism disposed above the second carrier 41, and a third pressing mechanism disposed above the third carrier 51. The first pressing mechanism is configured to press the extended solder tape at the first end of the battery string assembly onto the straight bus bar on the first carrier 31, and the first heating mechanism is configured to heat the straight bus bar pressed onto the first carrier 31 to weld the straight bus bar onto the extended solder tape at the first end of the battery string assembly. The second pressing mechanism is configured to press the extended solder tape in the middle of the battery string assembly onto the bent bus bar on the second carrier 41, and the second heating mechanism is configured to heat the bent bus bar pressed onto the second carrier 41 to weld the bent bus bar onto the extended solder tape in the middle of the battery string assembly. The third pressing mechanism is configured to press the extended solder tape at the second end of the battery string assembly onto the straight bus bar on the third carrier 51, and the third heating mechanism is configured to heat the straight bus bar pressed onto the third carrier 51 to weld the straight bus bar onto the extended solder tape at the second end of the battery string assembly.

[0107] By setting the welding device to include a first heating mechanism, a second heating mechanism, and a third heating mechanism, the welding device can synchronously weld the bus bar to the extended solder tapes at the first end and the second end of the battery string assembly, as well as the extended solder tape in the middle of the battery string assembly, thereby improving the bus bar welding efficiency. In addition, since the first heating mechanism, the second heating mechanism, and the third heating mechanism are respectively disposed within the first carrier 31, the second carrier 32, and the third carrier 33, the bus bar can be heated from below the bus bar, avoiding direct contact with the extended solder tape on the battery string assembly, thereby avoiding damage to the extended solder tape.

[0108] The first heating mechanism, the second heating mechanism, and the third heating mechanism can, for example, adopt electromagnetic heating to heat the bus bar.
