[0015] As a further improvement to the above scheme, the swivel includes an annular pad 3, which is connected to the ring rail 2. A number of arc grooves are evenly distributed on the upper end surface of the annular pad 3. A rotating column 4 is rotatably arranged in the arc groove. The rotating column 4 is supported on the periphery of the lower plane of the working plate 5. The rotating column 4 and the working plate 5 are supported by the annular pad 3, so that the working plate 5 forms a rolling friction with the rotating column 4 during the rotation process, so as to support the smooth rotation of the working plate 5 through the rolling friction between the rotating column 4 and the working plate 5.

[0016] As a further improvement of the above scheme, the clamping mechanism includes a baffle 9, which is vertically connected to the working plate 5.

The rotating shaft 11 is symmetrically connected to the clamp seat through the support 12. The baffle 9 is used to resist one side of the battery 17. The battery 17 is placed on the clamp seat. The weight of the battery 17 presses the support plate 13 of the clamp seat to tilt toward the baffle 9. The clamp seat rotates on the rotating shaft 11, and the clamp arm 14 of the clamp seat pushes and cooperates with the baffle 9 to clamp the battery 17.

[0018] The working principle of a filling device for filling a lithium battery 17 with maintenance liquid is as follows: first, the maintenance liquid is filled into the liquid tank 7, and then the battery 17 is clamped on the clamping mechanism and positioned accurately so that the liquid filling hole on the battery 17 is aligned with the liquid filling tube, and then the servo motor 18 drives the working plate 5 to produce intermittent rotation at intervals. When the battery 17 rotates to the bottom of the liquid filling tube through the working plate 5, the nozzle of the liquid filling tube contacts the liquid filling hole on the battery 17, and the battery 17 is filled with maintenance liquid. After the last battery 17 is filled, the working plate 5 rotates again to place the next battery 17 directly under the liquid filling tube, and rotates intermittently at intervals in sequence. At the same time, when the battery 17 is filled with the maintenance liquid, the battery 17 can be removed, and the battery 17 to be filled with maintenance liquid can be clamped again, and the operation is cyclic.
