[0029] The angle correction assembly 2 is disposed on the mounting plate 1 and drives the suction cup fixing plate 3 to move horizontally, so that the suction cup fixing plate 3 swings about the central axis of the rotating shaft assembly 4 .

[0030] Specifically, in the present embodiment, a plurality of suction cups 5 are sequentially arranged along the length direction of the suction cup fixing plate 3, and a distance is set between two adjacent suction cups 5. The suction cups 5 are used to absorb external battery cells, and multiple external battery cells are absorbed in series under the suction cup fixing plate 3. The shaft assembly 4 includes a shaft sleeve and a shaft rod, the shaft sleeve is fixedly connected to the mounting plate 1, the shaft rod is fixedly connected to the suction cup fixing plate 3, and the shaft rod is rotatably connected to the shaft sleeve, so as to realize the structural feature of the rotational connection of the suction cup fixing plate 3 relative to the mounting plate 1. Preferably, the central axis of the shaft sleeve coincides with the central axis of the mounting plate 1, and the center axis of the shaft rod is rotatably connected to the suction cup fixing plate 3. The central axis coincides with the central axis of the suction cup fixing plate 3, and the angle correction component 2 is installed on the edge of the mounting plate 1, that is, the angle correction component 2 and the rotating shaft component 4 are spaced apart, and the angle correction component 2 drives the suction cup fixing plate 3 to move in the horizontal plane, that is, to achieve the purpose of swinging the suction cup fixing plate 3 relative to the mounting plate 1, and to achieve the purpose of adjusting the rotation angle of the suction cup fixing plate 3, that is, to perform angle correction on several series-connected battery cells adsorbed by the suction cup 5, so that the central axis of multiple series-connected battery cells is consistent with the central axis of the external welding platform, thereby ensuring the stability of production quality.

[0031] By installing the angle correction component 2 on the mounting plate 1, the mounting plate 1 and the suction cup fixing plate 3 are connected through the rotating shaft component 4. The angle correction component 2 drives the suction cup fixing plate 3 to move in the horizontal plane so that the suction cup fixing plate 3 swings relative to the rotating shaft component 4, thereby achieving the purpose of adjusting the angle of the suction cup fixing plate 3, that is, adjusting the angle of multiple series-connected battery cells in the outside world, meeting production requirements and improving production quality.

[0035] The lower slider 233 is provided with a long hole 2302, and the length direction of the long hole 2302 is consistent with the length direction of the suction cup fixing plate 3. The connecting rod 232 is arranged in the long hole 2302, and the long hole 2302 is arranged along the X direction, which is convenient for adjusting the connection position of the connecting rod 232 and the lower slider 233, that is, adjusting the connection position of the suction cup fixing plate 3 relative to the upper slider 231, to meet the fine-tuning needs of different production requirements.
