The driving end of the third driving component is connected to the arc-shaped guide rail 21, and the third driving component is configured to drive the arc-shaped guide rail 21 to rotate so as to transport the busbars of different sizes to the battery cell.

[0026] It can be seen that the cooperation of the drive component 10, the conveying component 20 and the feeding component 30 makes the transportation of the busbar faster and more stable.

[0027] In one embodiment, the bow-shaped guide rail 21 includes a housing 210 and two racks 211, which are symmetrically arranged inside the housing 210.

[0028] As can be seen, the bow-shaped guide rail 21 consists of a housing 210 and two racks 211 symmetrically arranged inside the housing 210. This enhances the stability of the bow-shaped guide rail 21 and provides precise guidance for the reciprocating movement of the moving part 22 inside it. This allows the moving part 22 to run smoothly along the predetermined path, ensuring the positional accuracy and stability of the busbar during the conveying process and reducing deviations and vibrations.

[0029] In one embodiment, the moving part 22 includes a moving block 220, a motor 221, and a gripper 222. The gripper 222 is disposed at the top of the moving block 220, the fixed end of the motor 221 is disposed at the bottom of the moving block 220, the driving end of the motor 221 is disposed downward, and the driving part of the motor 221 is provided with a gear 223, which meshes with a rack 211.

[0030] Specifically, the gripper 222 can be set on the side wall of the moving block 220 near the first end of the bow-shaped guide rail 21.

[0031] As can be seen, the moving part 22 consists of a moving block 220, a motor 221, and a gripper 222. The motor 221 is fixed to the bottom of the moving block 220, with the drive end facing downward and equipped with a gear 223 that meshes with the rack 211. This allows the motor 221 to precisely control the movement of the moving block 220 through the transmission of the gear 223 and the rack 211, thereby enabling the gripper 222 to accurately grip and transport the busbar. The operator can control the motor 221 and adjust the position and speed of the moving block 220 according to actual needs.

[0032] In one embodiment, the snap-fit ​​member 23 is provided with a first clamping part 230 and a second clamping part 231 that abut against each other, and the end of the busbar passes through the abutting part of the first clamping part 230 and the second clamping part 231.

[0033] As can be seen, the snap-fit ​​part 23 is provided with a first clamping part 230 and a second clamping part 231 that abut against each other. The end of the busbar passes through the abutting part of the two, accurately positioning the end of the busbar and providing an accurate position for the moving part 22 to clamp. At the same time, the tight cooperation of the two clamping parts can effectively prevent the busbar from sliding or shifting during the clamping process, greatly improving the success rate and reliability of clamping and ensuring the stability of the busbar at the beginning of the delivery stage.

[0034] In one embodiment, the fuse 24 includes a heating element 240 and a cylinder 241.

The cylinder 241 is fixed on the arc-shaped guide rail 21, and the heating element 240 is set at its moving end. The cylinder 241 can precisely drive the heating element 240 to approach or move away from the busbar at the snap-fit ​​part 23. The heating position and time of the heating element 240 on the busbar can be precisely controlled according to production needs to achieve precise fuse-breaking of the busbar, meet the usage requirements of busbars of different lengths and specifications, and the heating fuse-breaking method may make the cut more flat and have little impact on the quality of the busbar.

[0036] In one embodiment, the feeding assembly 30 also includes a plurality of tensioning rollers 33, which are spaced apart between the first end of the conveying assembly 20 and the support seat 31.

[0037] As can be seen, multiple tensioning rollers 33 in the feeding assembly 30 are spaced apart between the first end of the conveying assembly 20 and the bearing seat 31, which can tension the busbar group and prevent problems such as loosening and tangling of the busbar during the conveying process, thus ensuring the stability and smoothness of the busbar conveying. At the same time, the operator can adjust the tension of the busbar by adjusting the tensioning rollers 33 according to the actual situation such as the material and specifications of the busbar, thereby improving the adaptability of the conveying assembly 20 to different types of busbars.

[0038] A battery cell welding device includes the aforementioned busbar conveying assembly.

[0039] The working principle of the above-mentioned busbar conveying assembly is as follows:

[0040] The third driving component drives the conveying assembly 20 to rotate at a preset angle as required. The first driving component drives the conveying assembly 20 to move to the welding station where the battery cell is placed. The gripper 222 moves with the moving block 220 to the first end of the bow-shaped guide rail 21 and clamps the end of the busbar from the snap-fit ​​23. As required, the moving component 22 pulls one end of the busbar to a preset position. The second driving component drives the conveying assembly 20 to descend, so that the busbar abuts against the battery cell. The welding assembly welds the busbar to the battery cell. The cylinder 241 drives the heating component 240 to melt the busbar on the snap-fit ​​23. The second driving component drives the conveying assembly 20 to reset.
