[0071] Among them, the driving wheel 222 and the driven wheel 221 are drivingly connected through a timing belt 223. When the driving member 224 drives the driving wheel 222 to rotate, the driven wheel 221 can be driven to rotate synchronously, and then the material distribution plate 21 can be driven to rotate synchronously. The driving member 224 can be set as a driving motor, and its output shaft is used to directly dock with the driving wheel 222 to drive the driving wheel 222 to rotate when the output shaft rotates; the driving member 224 can also be docked with the driving wheel 222 through gears or other transmission structures, which is not limited here.

[0081] The manipulator 52 may be a multi-axis manipulator 52 with multiple degrees of automation to improve the transfer flexibility of the manipulator 52, so as to facilitate the clamping of the battery 200, and to load the battery 200 to the corresponding product, so that the battery 200 and the product are docked and assembled. By making the manipulator 52 rotatable, the battery 200 can be driven to rotate 180° after the manipulator 52 clamps the battery 200, thereby realizing the correction function of the battery 200 in the reverse state.

[0082] In some embodiments, the transfer mechanism 51 may include a linear drive module and a transfer platform 511, and the transfer platform 511 is connected to the linear drive module by transmission, so as to move back and forth linearly under the drive of the linear drive module, so as to be docked with the material distribution component 20 and the manipulator 52 respectively.
