The liquid pump 23 and the liquid injector 21 are connected through the liquid guide tube 22, and the liquid inlet end of the liquid pump 23 is connected with the external liquid supply area. During specific use, the external liquid supply area is used to store electrolyte, and the external liquid supply area is sucked by the set liquid pump 23, so that the liquid injector 21 is guided by the liquid pump 23. The liquid guide tube 22 serves as a connecting pipe between the liquid pump 23 and the liquid injector 21, and is used to transport electrolyte. The liquid injector 21 is driven by the set cylinder 20 to reciprocate up and down, so that the liquid outlet end of the liquid injector 21 can be in close contact with the lithium battery, so as to perform liquid injection operation on the lithium battery.

[0022] As an implementation method in this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the drive assembly includes a drive motor 30 fixedly mounted on the upper end surface of the base 10, the output end of the drive motor 30 is fixedly connected to a drive shaft 31, a chassis 32 is fixedly mounted on the top of the drive shaft 31, an active dial 33 is fixedly connected to the upper end surface of the chassis 32, the active dial 33 is a semi-arc structure, a round pin 34 is fixedly mounted on the upper end surface of the active dial 33, a column 35 is fixedly connected to the upper end surface of the base 10, a driven sheave 36 is rotatably sleeved on the top outer wall of the column 35, the upper end surface of the driven sheave 36 is fixedly connected to the bottom end of the support rod 13, the driven sheave 36 is arranged above the chassis 32, a plurality of radial grooves 38 adapted to the round pin 34 are provided in an annular array on the driven sheave 36, and a concave locking arc 37 is provided in an annular array on the upper outer wall of the driven sheave 36. During specific use, the drive motor 30 is provided to drive the drive shaft 31 to rotate, and the drive shaft 31 drives the chassis 32 to rotate When the driving dial 33 rotates, the chassis 32 rotates, and the round pin 34 is driven to rotate when the chassis 32 rotates. When it does not enter the radial groove 38 of the driven groove wheel 36, the concave locking arc 37 of the driven groove wheel 36 is stuck by the outer concave surface of the outer surface of the active dial 33, so the driven groove wheel 36 does not move. When the chassis 32 rotates and drives the round pin 34 to enter the radial groove 38 of the driven groove wheel 36, the driven groove wheel 36 is driven by the round pin 34 to rotate, and when the round pin 34 leaves the radial groove 38 on the other side, the concave locking arc 37 is stuck again, and the driven groove wheel 36 is still again until the round pin 34 enters another radial groove 38 of the driven groove wheel 36 again, and the above movement is repeated, so that the driven groove wheel 36 performs intermittent motion of sometimes moving and sometimes stopping, and the driven groove wheel 36 drives the workbench 12 on the support rod 13 to perform intermittent motion synchronously, so as to provide sufficient injection time for the injector 21.

[0023] Working principle: When in use, the drive motor 30 is provided to drive the drive shaft 31 to rotate, and the drive shaft 31 drives the chassis 32 to rotate. When the chassis 32 rotates, the active dial 33 rotates synchronously, and when the chassis 32 rotates, the round pin 34 is driven to rotate. When it does not enter the radial groove 38 of the driven groove wheel 36, the concave locking arc 37 of the driven groove wheel 36 is stuck by the outer concave surface of the outer surface of the active dial 33, so the driven groove wheel 36 does not move. When the chassis 32 rotates and drives the round pin 34 to enter the radial groove 38 of the driven groove wheel 36, the driven groove wheel 36 is driven by the round pin 34 to rotate, and when the round pin 34 leaves the radial groove 38 on the other side, the concave locking arc 37 is stuck again, and the driven groove wheel 36 is stationary again until the round pin 34 enters the driven groove wheel again.

The liquid guide tube 22 serves as a connecting pipe between the liquid pump 23 and the injector 21, and is used to transport electrolyte. The injector 21 is driven by the provided cylinder 20 to perform reciprocating movement up and down, so that the liquid outlet end of the injector 21 can be in close contact with the lithium battery, so that the lithium battery is injected, and during the rotation of the workbench 12, the lithium battery after the injection is completed can be replaced.
