Description

Technical Field

[0001] This application relates to the field of photovoltaic cell module production equipment, specifically a busbar preparation device and a busbar welding device. Background Technology

[0002] Solar cell modules convert solar energy into electrical energy and are increasingly being adopted. During the production of solar cell modules, there is a process of welding busbars, which involves welding busbars to the extended solder strips at both ends and the middle of the cell string module. To facilitate subsequent junction box installation, the busbars welded to the middle extension of the cell string module are bent busbars with bent ends, which are then inserted into and welded to the junction box. The busbars welded to the extended solder strips at both ends of the cell string module are straight busbars without bending.

[0003] In the busbar welding process, it is necessary to prepare bent and straight busbars required for welding, and to supply the bent and straight busbars to the corresponding welding stations. Existing busbar preparation equipment includes three horizontally arranged support platforms—a first support platform, a second support platform, and a third support platform; a first straight busbar preparation mechanism and a bent busbar preparation mechanism located on one side of each support platform; a second straight busbar preparation mechanism located on the other side of each support platform; and a first transport mechanism and a second transport mechanism. The first transport mechanism is used to transport the straight busbars prepared by the first straight busbar preparation mechanism to the first support platform, and to transport the bent busbars prepared by the bent busbar preparation mechanism to the second support platform. The second transport mechanism is used to transport the straight busbars prepared by the second straight busbar preparation mechanism to the third support platform. Among them, the straight busbars transported to the first support platform are eventually welded to the long strip at the first end of the battery string assembly, the bent busbars transported to the second support platform are eventually welded to the long strip in the middle of the battery string assembly, and the straight busbars transported to the third support platform are eventually welded to the long strip at the second end of the battery string assembly.

[0004] Existing busbar preparation devices require two straight busbar preparation mechanisms to be set up on both sides of the welding station for straight busbars to be welded to both ends of the battery string assembly. Since two straight busbar preparation mechanisms are required, and each straight busbar preparation mechanism includes at least components such as a busbar unwinding assembly, a clamping assembly, a cutting assembly, a traction assembly, and a preparation table, the equipment structure of the busbar preparation device is relatively complex, the equipment maintenance workload is large, and the equipment cost is high. Summary of the Invention

[0005] To solve at least one of the above-mentioned technical problems, this application provides a busbar preparation apparatus, which adopts the following technical solution:

[0006] A busbar preparation apparatus includes a first preparation mechanism, a second preparation mechanism, a first supporting mechanism, a second supporting mechanism, a third supporting mechanism, a first transport mechanism, a second transport mechanism, and a transfer mechanism, wherein:

[0007] The first bearing mechanism, the second bearing mechanism, and the third bearing mechanism are arranged sequentially at intervals along the first horizontal direction and can move along the first horizontal direction respectively. The first bearing mechanism includes a first bearing platform, the second bearing mechanism includes a second bearing platform and a first buffer platform, and the third bearing mechanism includes a third bearing platform and a second buffer platform.

[0008] The first preparation mechanism is located on the side of the first support mechanism. The first preparation mechanism is configured to prepare a bent busbar. The first transport mechanism is configured to transport the bent busbar prepared by the first preparation mechanism to the second support platform.

[0009] The second preparation mechanism is located on the side of the third support mechanism. The second preparation mechanism is configured to prepare a straight busbar, and the second transport mechanism is configured to transport the straight busbar prepared by the second preparation mechanism to the third support platform or the second buffer platform.

[0010] The transfer mechanism is located between the third carrier mechanism and the second carrier mechanism. The transfer mechanism is configured to pick up the flat busbar on the second buffer platform and transport the picked-up flat busbar to the first buffer platform.

[0011] The first transport mechanism is also configured to pick up the flat busbars cached on the first buffer platform and transport the picked-up flat busbars to the first carrier platform.

[0012] The busbar fabrication apparatus provided in this application requires only one straight busbar fabrication mechanism. Through the cooperation of a first transport mechanism, a second transport mechanism, a first buffer platform, a second buffer platform, and a transfer mechanism, straight busbars can be supplied to the first and third support platforms respectively, meeting the welding requirements of straight busbars at both ends of the battery string assembly. Compared with existing busbar fabrication apparatuses, the complex straight busbar fabrication mechanism is replaced by a simpler first buffer platform, a second buffer platform, and a transfer mechanism. While ensuring busbar fabrication efficiency, the structural complexity and cost of the busbar fabrication apparatus in this application are reduced, and the daily maintenance work of the straight busbar fabrication mechanism on one side is also eliminated.

[0013] In some embodiments, the first conveying 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, the first driving module is configured to drive the first adsorption component to translate and move up and down; the first adsorption component is configured to, under the drive of the first driving module, pick up bent busbars from the first preparation mechanism and transport the picked up bent busbars to the second support platform, and pick up straight busbars from the first buffer platform and transport the picked up straight busbars to the first support platform.

[0014] A simple first transport mechanism is provided, which drives a first adsorption component to translate and lift via a first drive module, so as to drive the first adsorption component to pick up bent busbars from a first preparation mechanism and transport the picked-up bent busbars to a second support platform, and pick up straight busbars from a first buffer platform and transport the picked-up straight busbars to the first support platform.

[0015] In some embodiments, the first transport mechanism includes two first adsorption components connected side by side to the drive end of the first drive module. When one of the first adsorption components releases a bent busbar picked up from the first preparation mechanism onto the second carrier stage, the other first adsorption component picks up a straight busbar from the first buffer stage.

[0016] By setting up two first adsorption components, the first transport mechanism can simultaneously pick up a straight busbar from the first buffer platform while transporting the bent busbar from the first preparation mechanism to the second support platform, thereby improving the transport efficiency of the busbar by the first transport mechanism.

[0017] In some embodiments, the second transport mechanism includes a second drive module and at least one second adsorption component, wherein: the second adsorption component is connected to the drive end of the second drive module, the second drive module is configured to drive the second adsorption component to translate and move up and down; the second adsorption component is configured to, under the drive of the second drive module, pick up the straight manifold from the second preparation mechanism and transport the picked up straight manifold to the third support stage or the second buffer stage.

[0018] A simple second transport mechanism is provided, which drives the second adsorption component to translate and lift via a second drive module, so as to drive the second adsorption component to pick up the straight manifold from the second preparation mechanism and transport the picked-up straight manifold to the third support platform or the second buffer platform.

[0019] In some embodiments, the second transport mechanism includes two second adsorption components connected side by side to the drive end of the second drive module. The two second adsorption components are configured to pick up a straight manifold from the second preparation mechanism and transport the picked-up straight manifold to the third support stage and the second buffer stage, respectively.

[0020] By setting two second adsorption components, the second transport mechanism can pick up two sets of straight manifolds from the second preparation mechanism and then move them to the third support platform and the second buffer platform respectively, thereby improving the transport efficiency of the manifolds by the second transport mechanism.

[0021] In some embodiments, a first suction hole and a positioning pin assembly are provided on the surface of both the first buffer platform and the second buffer platform. The positioning pin assembly includes a first positioning pin and a second positioning pin spaced apart, and the distance between the first positioning pin and the second positioning pin matches the width of the straight busbar.

[0022] The first adsorption hole can adsorb and fix the straight busbar cached on the first or second buffer platform. The first positioning pin and the second positioning pin can limit the straight busbar cached on the first or second buffer platform from both sides to prevent the straight busbar from slipping or shifting position.

[0023] In some embodiments, a second adsorption hole is provided on the surface of the first support platform, the second support platform, and the third support platform.

[0024] By setting second adsorption holes on the surfaces of the first, second, and third support platforms, the first, second, and third support platforms can all adsorb and fix the bent or straight busbars transported to them, ensuring the welding accuracy of the busbars.

[0025] In some embodiments, the busbar preparation device further includes a slide rail arranged along a first horizontal direction; the first bearing mechanism, the second bearing mechanism and the third bearing mechanism are all slidably connected to the slide rail and can all slide along the slide rail to implement position adjustment in the first horizontal direction; or, the first bearing mechanism, the second bearing mechanism, the third bearing mechanism and the transfer mechanism are all slidably connected to the slide rail and can all slide along the slide rail to implement position adjustment in the first horizontal direction.

[0026] By slidingly connecting the first, second, and third support mechanisms onto the same slide rail, the structure is simple and compact. This design guides the movement of the first, second, and third support mechanisms in the first horizontal direction, ensuring that the straight busbars transported to the first and third support mechanisms are located below the extended solder strips at the first and second ends of the battery string assembly, respectively. The bent busbars on the second support mechanism are located below the extended solder strips in the middle of the battery string assembly. Furthermore, by sliding the transfer mechanism onto the slide rail, stable movement between the second fabrication mechanism and the second support mechanism is achieved, resulting in an even more compact structure.

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

[0028] The first lifting drive module drives the first support platform to rise, allowing the straight busbars on the first support platform to abut against the extended solder strip at the first end of the battery string assembly, ultimately ensuring that the straight busbars on the first support platform are welded to the extended solder strip at the first end of the battery string assembly. The second lifting drive module drives the second support platform to rise, allowing the bent busbars on the second support platform to abut against the extended solder strip in the middle of the battery string assembly, ultimately ensuring that the bent busbars on the second support platform are welded to the extended solder strip in the middle of the battery string assembly. The third lifting drive module drives the third support platform to rise, allowing the straight busbars on the third support platform to abut against the extended solder strip at the second end of the battery string assembly, ultimately ensuring that the straight busbars on the third support platform are welded to the extended solder strip at the second end of the battery string assembly.

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

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

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

[0032] The welding pickup device is configured to pick up the battery string assembly to be welded and transport it above the busbar preparation device. The first support platform is used to transport the straight busbar to the bottom of the long welding strip at the first end of the battery string assembly. The second support platform is used to transport the bent busbar to the bottom of the long welding strip in the middle of the battery string assembly. The third support platform is used to transport the straight busbar to the bottom of the long welding strip at the second end of the battery string assembly.

[0033] The welding apparatus is configured to weld a straight busbar located on a first support platform to a long strip at the first end of the battery string assembly, to a bent busbar located on a second support platform to a long strip in the middle of the battery string assembly, and to weld a straight busbar located on a third support platform to a long strip at the second end of the battery string assembly.

[0034] The busbar preparation device enables the preparation of busbars, as well as the carrying, moving, and welding support of the busbars. The welding pick-up device moves the battery string assembly with the busbars to be welded to the top of the busbar preparation device. The welding device then welds the busbars onto the extended welding strip of the battery string assembly. While the welding device is welding the busbars, the busbar preparation device can simultaneously prepare and transport the busbars, improving efficiency.

[0035] In some embodiments, the welding apparatus includes a first welding mechanism, a second welding mechanism, and a third welding mechanism, wherein: the first welding mechanism is disposed above a first support platform and configured to weld a straight busbar located on the first support platform to a long weld strip at the first end of the battery string assembly; the second welding mechanism is disposed above a second support platform and configured to weld a bent busbar located on the second support platform to a long weld strip at the middle of the battery string assembly; and the third welding mechanism is disposed above a third support platform and configured to weld a straight busbar located on the third support platform to a long weld strip at the second end of the battery string assembly.

[0036] By configuring the welding device to include a first welding mechanism, a second welding mechanism, and a third welding mechanism, the welding device can simultaneously weld the busbar to the extended welding strips at the first and second ends of the battery string assembly, as well as the extended welding strips in the middle of the battery string assembly, thereby improving the busbar welding efficiency.

[0037] In some embodiments, the welding apparatus includes a first heating mechanism, a second heating mechanism, and a third heating mechanism, wherein the first heating mechanism is disposed within a first support platform, the second heating mechanism is disposed within a second support platform, and the third heating mechanism is disposed within a third support platform; the busbar welding equipment further includes a clamping device, which includes a first clamping mechanism disposed above the first support platform, a second clamping mechanism disposed above the second support platform, and a third clamping mechanism disposed above the third support platform; the first clamping mechanism is configured to clamp the extended welding strip at the first end of the battery string assembly onto the straight busbar on the first support platform, and the first heating mechanism is configured to heat the first... A straight busbar on a support platform is used to weld the straight busbar to the extended solder strip at the first end of the battery string assembly; a second clamping mechanism is configured to clamp the extended solder strip in the middle of the battery string assembly onto a bent busbar on a second support platform; a second heating mechanism is configured to heat the bent busbar on the second support platform to weld the bent busbar to the extended solder strip in the middle of the battery string assembly; a third clamping mechanism is configured to clamp the extended solder strip at the second end of the battery string assembly onto a straight busbar on a third support platform; a third heating mechanism is configured to heat the straight busbar on the third support platform to weld the straight busbar to the extended solder strip at the second end of the battery string assembly.

[0038] By configuring the welding device to include a first heating mechanism, a second heating mechanism, and a third heating mechanism, the welding device can simultaneously weld the busbar to the extended welding strips at the first and second ends of the battery string assembly, as well as the extended welding strips in the middle of the battery string assembly, thereby improving the busbar welding efficiency.

[0056] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] like Figures 1 to 5 As shown, the busbar preparation device in this embodiment includes a first preparation mechanism 1, a second preparation mechanism 2, a first bearing mechanism 3, a second bearing mechanism 4, a third bearing mechanism 5, a first transport mechanism 6, a second transport mechanism 7, and a transfer mechanism 8, wherein:

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

[0059] The first preparation mechanism 1 is located on the side of the first support mechanism 3. The first preparation mechanism 1 is configured to prepare a bent busbar. The first transport mechanism 6 is configured to transport the bent busbar prepared by the first preparation mechanism 1 to the second support platform 41.

[0060] The second preparation mechanism 2 is located on the side of the third support mechanism 5. The second preparation mechanism 2 is configured to prepare a straight busbar, and the second transport mechanism 7 is configured to transport the straight busbar prepared by the second preparation mechanism 2 to the third support platform 51 or the second buffer platform 52.

[0061] The transfer mechanism 8 is disposed between the third carrier mechanism 5 and the second carrier mechanism 4. The transfer mechanism 8 is configured to pick up the flat busbars cached on the second buffer platform 52 and transport the picked-up flat busbars to the first buffer platform 42.

[0062] The first transport mechanism 6 is also configured to pick up the flat busbars cached on the first buffer stage 42 and transport the picked-up flat busbars to the first carrier stage 31.

[0063] The first preparation mechanism 1 can be any of the existing bending busbar preparation mechanisms, and the second preparation mechanism 2 can be any of the existing straight busbar preparation mechanisms.

[0064] The optional operating process of the busbar preparation device in this embodiment is as follows:

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

[0066] The first transport mechanism 6 transports the bent busbars prepared by the first preparation mechanism 1 to the second support platform 41. At the same time, the second transport mechanism 7 transports the straight busbars prepared by the second preparation mechanism 2 to the third support platform 51 and the second buffer platform 52. The second transport mechanism 7 can pick up two sets of straight busbars from the second preparation mechanism 2 in two separate operations, and after picking up one set of straight busbars, it immediately transports the straight busbars to the third support platform 51 or the second buffer platform 52. Alternatively, the second transport mechanism 7 can pick up two sets of straight busbars from the second preparation mechanism 2 in two separate operations, and after the two picking operations are completed, it simultaneously transports the two sets of straight busbars to the third support platform 51 and the second buffer platform 52.

[0067] The transfer mechanism 8 picks up the straight busbars cached on the second buffer stage 52 and transports them to the first buffer stage 42. The first transport mechanism 6 then picks up the straight busbars from the first buffer stage 42 and transports them to the first support stage 31. Furthermore, after the second buffer stage 52 is emptied, the second transport mechanism 7 picks up another set of straight busbars from the second preparation mechanism 2 and caches them on the second buffer stage 52.

[0068] At this point, the first support platform 31, the second support platform 41, and the third support platform 51 all carry the busbars required for the first round of busbar welding, while the second buffer platform 52 buffers the straight busbars required for the second round of busbar welding.

[0069] The first round of busbar welding is performed as follows: After the battery string assembly to be welded is moved above the busbar preparation device, the first support mechanism 3, the second support mechanism 4, and the third support mechanism 5 are controlled to translate horizontally according to the positions of the extended welding strips at the first, middle, and second ends of the battery string assembly. This ensures that the first support platform 31, the second support platform 41, and the third support platform 51 are positioned at the first, second, and third welding positions, respectively. This ensures that the straight busbar on the first support platform 31 is below the extended welding strip at the first end of the battery string assembly, the bent busbar on the second support platform 41 is below the extended welding strip at the middle of the battery string assembly, and the straight busbar on the third support platform 51 is below the extended welding strip at the second end of the battery string assembly. This ensures that the busbars can be welded to the corresponding extended welding strips. After the busbar welding is completed, the first support mechanism 3, the second support mechanism 4, and the third support mechanism 5 are controlled to move back to their original positions.

[0070] While performing the first round of busbar welding, the transfer mechanism 8 moves the straight busbars cached on the second buffer platform 52 to the first buffer platform 42, preparing for the second round of busbar welding. Of course, the transfer mechanism 8 can also move the straight busbars cached on the second buffer platform 52 to the first buffer platform 42 before performing the first round of busbar welding.

[0071] After the first round of busbar welding is completed, since straight busbars are already buffered on the first buffer platform 42, before the second round of busbar welding, the first transport mechanism 6, after transporting the bent busbars prepared by the first preparation mechanism 1 to the second support platform 41, can immediately pick up the pre-buffered straight busbars from the first buffer platform 42 and transport them to the first support platform 31, thus ensuring the working cycle time. At the same time, the second transport mechanism 7 transports the straight busbars prepared by the second preparation mechanism 2 to the third support platform 51 and the second buffer platform 52.

[0072] At this point, the first support platform 31, the second support platform 41, and the third support platform 51 all carry the busbars required for the second round of busbar welding, while the second buffer platform 52 buffers the straight busbars required for the third round of busbar welding.

[0073] The second round of busbar welding is performed in the same manner as the first round, and will not be described again here. Similarly, during or before the second round of busbar welding, the transfer mechanism 8 moves the straight busbars buffered on the second buffer platform 52 to the first buffer platform 42, preparing for the third round of busbar welding.

[0074] As can be seen, the busbar preparation device of this application embodiment only needs to set up a straight busbar preparation mechanism (i.e., the second preparation mechanism 2). Through the cooperation of the first transport mechanism 6, the second transport mechanism 7, the first buffer platform 42, the second buffer platform 52 and the transfer mechanism 8, straight busbars can be supplied to the first support platform 31 and the third support platform 51 respectively, so as to meet the welding requirements of the straight busbars at both ends of the battery string assembly.

[0075] Compared to existing busbar fabrication devices, the complex straight busbar fabrication mechanism is replaced by a simple first buffer platform 42, a second buffer platform 52, and a transfer mechanism 8. While ensuring busbar fabrication efficiency, the structural complexity and cost of the busbar fabrication device in this embodiment are reduced, and the daily maintenance of the straight busbar fabrication mechanism on one side is also eliminated.

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

[0077] Furthermore, before or during the current round of busbar welding, the first buffer platform 42 has already buffered the straight busbars required for the next round of busbar welding. Therefore, before the next round of busbar welding, the first transport mechanism 6 can directly pick up the pre-buffered straight busbars from the first buffer platform 42 without waiting for the transfer mechanism 8 to buffer the straight busbars onto the first buffer platform 42, thus ensuring the working cycle time.

[0078] like Figure 6 As shown, optionally, the first conveying 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 move up and down. The first adsorption component 62 is configured to, under the drive of the first driving module 61, pick up bent busbars from the first preparation mechanism 1 and transport the picked-up bent busbars to the second support platform 41, and pick up straight busbars from the first buffer platform 42 and transport the picked-up straight busbars to the first support platform 31.

[0079] The first drive module 61 can be any existing drive module capable of driving the first adsorption component 62 to translate and move up and down. For example, the first drive module 61 includes a translation drive unit and a lifting drive unit, wherein the lifting drive unit is connected to the drive end of the translation drive unit, and the first adsorption component 62 is connected to the drive end of the lifting drive unit. The translation drive unit is used to drive the first adsorption component 62 to translate, and the lifting drive unit is used to drive the first adsorption component 62 to move up and down. The first adsorption component 62 can be, for example, a plurality of suction cups arranged at intervals, which cooperate to pick up bent or straight manifolds.

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

[0081] Optionally, the first transport mechanism 6 includes two first adsorption components 62 connected side-by-side to the drive end of the first drive module 61. The transport process of the first transport mechanism 6 is as follows: First, the first drive module 61 drives the two first adsorption components 62 above the first preparation mechanism 1, where one of the first adsorption components 62 picks up a bent manifold from the first preparation mechanism 1. Subsequently, the first drive module 61 drives the two first adsorption components 62 above the second support mechanism 4, where one of the first adsorption components 62 releases the bent manifold onto the second support platform 41, while the other first adsorption component 62 simultaneously picks up a straight manifold from the first buffer platform 42. Finally, the first drive module 61 drives the two first adsorption components 62 above the first support mechanism 3, where the other first adsorption component 62 releases the straight manifold onto the first support platform 31.

[0082] As can be seen, by setting two first adsorption components 62, the first transport mechanism 6 can pick up straight manifolds from the first buffer stage 42 while transporting the bent manifolds on the first preparation mechanism 1 to the second support stage 41, thereby improving the transport efficiency of the first transport mechanism 6 for manifolds.

[0083] Of course, in order to save equipment costs, the first transport mechanism 6 may also include only a first adsorption component 62. In this case, after the first transport mechanism 6 transports the bent busbar on the first preparation mechanism 1 to the second support platform 41, it picks up the straight busbar from the first buffer platform 42 and transports the straight busbar to the first support platform 31.

[0084] like Figure 7 As shown, optionally, the second conveying mechanism 7 includes a second driving module 71 and at least one second adsorption component 72, wherein: 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 move up and down. The second adsorption component 72 is configured to, under the drive of the second driving module 71, pick up the straight manifold from the second preparation mechanism 2 and transport the picked-up straight manifold to the third support platform 51 or the second buffer platform 52.

[0085] The second drive module 71 can be any existing drive module capable of driving the second adsorption component 72 to translate and move up and down. For example, the second drive module 71 includes a translation drive unit and a lifting drive unit, wherein the lifting drive unit is connected to the drive end of the translation drive unit, and the second adsorption component 72 is connected to the drive end of the lifting drive unit. The translation drive unit is used to drive the second adsorption component 72 to translate, and the lifting drive unit is used to drive the second adsorption component 72 to move up and down. The second adsorption component 72 may, for example, include a plurality of suction cups arranged at intervals, which cooperate to pick up the straight manifold.

[0086] Of course, other structures of handling mechanisms capable of moving the busbars can also be used as the second handling mechanism 7, such as a suction component driven by a robotic arm.

[0087] Optionally, the second transport mechanism 7 includes two second adsorption components 72 connected side by side to the drive end of the second drive module 71. The two second adsorption components 72 are configured to pick up a straight manifold from the second preparation mechanism 2 and transport the picked-up straight manifold to the third support platform 51 and the second buffer platform 52 respectively.

[0088] By setting two second adsorption components 72, the second transport mechanism 7 can pick up two sets of straight busbars from the second preparation mechanism 3 and then transport the two sets of straight busbars to the third support platform 51 and the second buffer platform 52 respectively, thereby improving the transport efficiency of the busbars by the second transport mechanism 7. The number of each set of straight busbars is determined according to the number of busbars to be welded in the current wheel, and can be one, two or more.

[0089] Of course, in order to save equipment costs, the second transport mechanism 7 may also include only a second adsorption component 72. In this case, the second transport mechanism 7 picks up a set of straight manifolds from the second preparation mechanism 3 in two separate steps, and transports the picked-up straight manifolds to the third support platform 51 and the second buffer platform 52 respectively.

[0090] Optionally, both the first buffer platform 42 and the second buffer platform 52 are provided with a first suction hole and a positioning pin assembly. The positioning pin assembly includes a first positioning pin and a second positioning pin spaced apart, with the distance between the first positioning pin and the second positioning pin matching the width of the straight busbar. The first suction hole can adsorb and fix the straight busbar buffered on the first buffer platform 42 or the second buffer platform 52, while the first positioning pin and the second positioning pin can limit the straight busbar buffered on the first buffer platform 42 or the second buffer platform 52 from both sides, preventing the straight busbar from slipping or shifting position.

[0091] Optionally, the first support platform 31, the second support platform 41 and the third support platform 51 are all provided with second adsorption holes, and the first support platform 31, the second support platform 41 and the third support platform 51 can adsorb and fix the bent busbar or straight busbar transported to them through the second adsorption holes.

[0092] like Figures 1 to 5As shown, optionally, the busbar preparation device in this embodiment further includes a slide rail 9 arranged along a first horizontal direction. The first support mechanism 3, the second support mechanism 4, and the third support mechanism 5 are all slidably connected to the slide rail 9 and can all slide along the slide rail 9 to perform position adjustment in the first horizontal direction. Before welding the busbars, by controlling the first support mechanism 3, the second support mechanism 4, and the third support mechanism 5 to slide along the slide rail 9, it can be ensured that the straight busbars transported to the first support mechanism 3 and the third support mechanism 5 are located below the extended welding strips at the first and second ends of the battery string assembly, respectively, while the bent busbars transported to the second support mechanism 4 are located below the extended welding strips in the middle of the battery string assembly. Furthermore, since the first support mechanism 3, the second support mechanism 4, and the third support mechanism 5 all slide along the slide rail 9, it can be ensured that the first support mechanism 3, the second support mechanism 4, and the third support mechanism 5 remain aligned in the first horizontal direction.

[0093] Optionally, the first bearing mechanism 3, the second bearing mechanism 4 and the third bearing mechanism 5 are all driven by independent drive 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, so that the transfer mechanism 8 can slide stably along the slide rail 9 to perform reciprocating movement between the second preparation mechanism 2 and the second support mechanism 3. Optionally, as... Figure 1 As shown, the transfer mechanism 8 includes a drive unit (not shown), a base 81, a frame 82, and several suction cups 83 mounted on the frame 82. The base 81 is slidably connected to the slide rail 9 and connected to the drive end of the drive unit. When the drive unit drives the base to move towards the third support mechanism 5, the second buffer platform 52 enters the frame 82, and the suction cups 83 on the frame 82 pick up the straight busbar on the second buffer platform 52. When the drive unit drives the base to move towards the second support mechanism 4, the first buffer platform 42 enters the frame 82, and the suction cups 83 on the frame 82 release the picked-up straight busbar onto the first buffer platform 42.

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

[0096] When the battery string assembly with the busbars to be welded is moved above the busbar preparation device, with the straight busbars on the first support mechanism 3 and the third support mechanism 5 located below the extended welding strips at the first and second ends of the battery string assembly, respectively, and the bent busbars on the second support mechanism 4 located below the extended welding strips in the middle of the battery string assembly, the first support platform 31 is raised by the first lifting drive module, allowing the straight busbars on the first support platform 31 to abut against the extended welding strips at the first end of the battery string assembly. The second support platform 41 is raised by the second lifting drive module, allowing the bent busbars on the second support platform 41 to abut against the extended welding strips in the middle of the battery string assembly. The third support platform 51 is raised by the third lifting drive module, allowing the straight busbars on the third support platform 51 to abut against the extended welding strips at the second end of the battery string assembly. This ensures that the welding mechanism can weld the busbars to the corresponding extended welding strips.

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

[0098] With this configuration, the transfer mechanism 8 can simultaneously perform welding on the busbars on the three support platforms, while picking up the straight busbars awaiting welding in the next round from the second buffer platform 52 and transporting them to the first buffer platform 42. The transfer mechanism 8 will not interfere with the welding of the busbars on the second and third support platforms 41 during this transfer. After welding is completed, the first transport mechanism 6 can transport the straight busbars from the first buffer platform 42 to the first support platform 31, ensuring a timely supply of busbars to the first support platform 31, thereby maintaining the work cycle and improving the busbar welding efficiency.

[0099] This application embodiment also provides a busbar welding device, which includes the busbar preparation device, welding pickup device, and welding device provided in any of the above embodiments, wherein:

[0100] The welding pickup device is configured to pick up the battery string assembly to be welded and transport it above the busbar preparation device. The first support platform 31 is used to transport the supported straight busbar to below the long welding strip at the first end of the battery string assembly. The second support platform 41 is used to transport the supported bent busbar to below the long welding strip in the middle of the battery string assembly. The third support platform 51 is used to transport the supported straight busbar to below the long welding strip at the second end of the battery string assembly.

[0101] The welding apparatus is configured to weld a straight busbar located on the first support platform 31 to the extended welding strip at the first end of the battery string assembly, to weld a bent busbar located on the second support platform 41 to the extended welding strip in the middle of the battery string assembly, and to weld a straight busbar located on the third support platform 51 to the extended welding strip at the second end of the battery string assembly.

[0102] As can be seen, the busbar preparation device realizes the preparation of busbars, as well as the support, movement, and welding of the busbars. The welding pickup device moves the battery string assembly with the busbars to be welded to above the busbar preparation device. The welding device welds the busbars to the extended welding strip of the battery string assembly. While the welding device is welding the busbars, the busbar preparation device can simultaneously perform busbar preparation and handling, improving the busbar welding efficiency.

[0103] In one optional embodiment, the welding apparatus includes a first welding mechanism, a second welding mechanism, and a third welding mechanism, wherein: the first welding mechanism is disposed above the first support platform 31 and configured to weld straight busbars located on the first support platform 31 to the extended welding strip at the first end of the battery string assembly; the second welding mechanism is disposed above the second support platform 41 and configured to weld bent busbars located on the second support platform 41 to the extended welding strip at the middle of the battery string assembly; and the third welding mechanism is disposed above the third support platform 51 and configured to weld straight busbars located on the third support platform 51 to the extended welding strip at the second end of the battery string assembly.

[0104] By configuring the welding device to include a first welding mechanism, a second welding mechanism, and a third welding mechanism, the welding device can simultaneously weld the busbar to the extended welding strips at the first and second ends of the battery string assembly, as well as the extended welding strips in the middle of the battery string assembly, thereby improving the busbar welding efficiency.

[0105] The first, second, and third welding mechanisms can employ various existing busbar welding mechanisms. For example, the first welding mechanism can use a liftable thermoplastic welding head. During welding, the thermoplastic welding head descends to press the extended weld strip at the first end of the battery string assembly downwards onto the straight busbar located on the first support platform 31 and heat it, thereby welding the straight busbar to the extended weld strip. Alternatively, the first welding mechanism can include a pressing part and a laser welding head. The pressing part is used to press the extended weld strip at the first end of the battery string assembly downwards onto the straight busbar located on the first support platform 31, and the laser welding head is used to perform laser welding on the pressed extended weld strip and the straight busbar, thereby welding the straight busbar to the extended weld strip.

[0106] In another alternative embodiment, the welding apparatus includes a first heating mechanism, a second heating mechanism, and a third heating mechanism, wherein the first heating mechanism is disposed within a first support platform 31, the second heating mechanism is disposed within a second support platform 41, and the third heating mechanism is disposed within a third support platform 51. The busbar welding equipment further includes a clamping device, comprising a first clamping mechanism disposed above the first support platform 31, a second clamping mechanism disposed above the second support platform 41, and a third clamping mechanism disposed above the third support platform 51. The first clamping mechanism is configured to clamp the extended solder strip at the first end of the battery string assembly onto the straight busbar on the first support platform 31, and the first heating mechanism is configured to heat the straight busbar clamped onto the first support platform 31 to weld the straight busbar onto the extended solder strip at the first end of the battery string assembly. The second clamping mechanism is configured to clamp the extended solder strip in the middle of the battery string assembly onto the bent busbar on the second support platform 41. The second heating mechanism is configured to heat the bent busbar clamped onto the second support platform 41 to weld the bent busbar onto the extended solder strip in the middle of the battery string assembly. The third clamping mechanism is configured to clamp the extended solder strip at the second end of the battery string assembly onto the straight busbar on the third support platform 51. The third heating mechanism is configured to heat the straight busbar clamped onto the third support platform 51 to weld the straight busbar onto the extended solder strip at the second end of the battery string assembly.

[0107] By configuring the welding device to include a first heating mechanism, a second heating mechanism, and a third heating mechanism, the welding device can simultaneously weld the busbar to the extended solder strips at the first and second ends of the battery string assembly, as well as the extended solder strip in the middle of the battery string assembly, thereby improving the busbar welding efficiency. Furthermore, since the first, second, and third heating mechanisms are respectively located within the first support platform 31, the second support platform 32, and the third support platform 33, heating of the busbar can be performed from below, avoiding direct contact with the extended solder strips on the battery string assembly and thus preventing damage to the extended solder strips.

[0108] The first, second, and third heating mechanisms can, for example, use electromagnetic heating to heat the busbar.
