[0048] 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.

[0049] A battery string consists of solder ribbons and battery cells stacked in a predetermined order, with multiple battery cells welded together by solder ribbons to achieve electrical connection. A common welding process for battery cell string welding involves first receiving multiple battery cells through a processing mechanism and arranging them to form a battery cell assembly. Then, a transport mechanism moves the battery cell assembly from the processing mechanism to a conveying mechanism. The conveying mechanism receives the solder ribbons and battery cell assembly and transports them to the welding station, where a welding mechanism performs welding on the solder ribbons and battery cell assembly at the welding station.

[0050] Existing handling mechanisms typically include a drive assembly and a pickup assembly. The drive assembly connects to the pickup assembly at its drive end. The drive assembly drives the pickup assembly to a processing mechanism to pick up the battery cell packs. The drive assembly then drives the pickup assembly and battery cell packs to a conveying mechanism to release the battery cell packs onto the conveying mechanism. However, the existing handling mechanisms have a pickup assembly mounted on a single-sided cantilever at the drive end of the drive assembly. The handling mechanism relies solely on the cantilever to bear the weight of the pickup assembly, battery cell packs, and other components. After prolonged operation, the cantilever may deform, causing the pickup assembly to become skewed and unable to accurately pick up the battery cell packs.

[0051] Therefore, this application proposes a battery cell handling mechanism 10, please refer to [link to relevant documentation]. Figure 1 As shown, the battery cell handling mechanism 10 proposed in this embodiment includes a base 11, a first drive assembly 12, two support members 13, a mounting base 14, a second drive assembly 15, and a pickup assembly 16. The first drive assembly 12 is mounted on the base 11, and the two support members 13 are positioned along a first horizontal direction (…). Figure 1 The two support members 13 are arranged parallel to each other in the X direction, and their bottom ends are along the second horizontal direction. Figure 1 The first drive assembly 12 is slidably mounted on the base 11 in the Y direction. The first horizontal direction is perpendicular to the second horizontal direction. The drive end of the first drive assembly 12 is connected to at least one support member 13. The mounting base 14 is slidably mounted on the two support members 13 at both ends along the first horizontal direction. The second drive assembly 15 is mounted on the two support members 13 and is configured to drive the mounting base 14 to move up and down. The first drive assembly 12 is configured to drive the two support members 13 to move alternately to the first station and the second station along the second horizontal direction.

One side of the first transmission belt 122 is fixedly connected to one of the two supports 13.
