The battery 4 drops into the placing chamber and moves to the right with the conveyor belt 2. When the battery 4 falls into the placing cavity, the hydraulic cylinder in the placing cavity is started, and the hydraulic cylinder pushes the liquid outlet pipe 23 rightwards, so that the liquid outlet nozzle 24 moves rightwards and is clamped into the liquid inlet hole of the battery 4. Meanwhile, as shown in fig. 4, the battery 4 can be placed in the placing cavity at the upper part of the transmission belt for liquid injection, but the battery 4 cannot be placed in the placing cavity at the lower part, so that the inserting plate 25 is arranged, when the liquid outlet pipe 23 rotates to the upper part along with the transmission belt 2, the inserting plate 25 slides downwards under the action of gravity, the liquid inlet hole of the liquid outlet nozzle 24 is no longer blocked, the liquid outlet nozzle 24 is opened, and the electrolyte flows out of the battery 4 under the negative pressure action of the vacuum chamber 1 to inject the liquid into the battery 4. As shown in fig. 5, when the outlet pipe 23 rotates to the lower part along with the conveyor belt 2, the insert plate 25 blocks the outlet nozzle 24 under the action of gravity, so as to reduce the outflow and waste of the electrolyte.

The battery 4 finishes injecting liquid in the transportation process of the conveyor belt 2, when the battery 4 is transported to the right end along with the conveyor belt 2, the battery 4 overturns and drops on the partition plate 3, the conveyor belt 2 continues to move, and the battery 4 drops into the second through hole 17. The second driving mechanism operates in accordance with the first driving mechanism, and the second turntable 16 is driven to rotate intermittently. After being rotated out of the vacuum bin 1, the second through hole 17 falls on the feeding table, slides along the feeding table and is fed to the next procedure for processing. When the second through hole 17 continues to rotate to a position between the second cover plate 18 and the second support plate 19, the second air pumping cylinder 20 pumps the air in the second through hole 17, so that the second through hole 17 is kept in a vacuum state. The second through hole 17 continues to rotate into the vacuum chamber 1, receiving the dropped battery 4.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
