[0022] In this embodiment, the driving mechanism 2 includes a sliding groove 14 longitudinally formed at the middle position of the top of the bottom plate 1. The cross-sectional shape of the sliding groove 14 is "T"-shaped. A slider 15 is limitedly and slidably arranged inside the sliding groove 14. A screw rod 16 is longitudinally rotatably installed inside the sliding groove 14. The slider 15 is screwed and installed on the screw rod 16 through a threaded hole. A servo motor is fixedly arranged at the position corresponding to the screw rod 16 at the rear end of the bottom plate 1. The output shaft of the servo motor is fixedly connected to one end of the screw rod 16. The slider 15 is fixedly arranged at the bottom of the moving plate 3. The sliding groove 14 and the slider 15 can limit each other, improving the stability of the moving plate 3 during movement. By driving the screw rod 16 with the servo motor, it is convenient to move the slider 15 and the moving plate 3, facilitating the subsequent movement of the placement plate 4 and the lithium-ion battery 12.

[0023] In this embodiment, the positioning mechanism includes a positioning groove 9 and positioning rods. The positioning grooves 9 are symmetrically formed on both sides of the top of the moving plate 3. The positioning rods are fixedly arranged at the four corner positions of the bottom of the placement plate 4. The positioning rods are inserted into the positioning grooves 9. The placement grooves 13 are arranged in a matrix on the top of the placement plate 4. The lithium-ion battery 12 is arranged inside the placement grooves 13. The axes of the placement grooves 13 and the liquid injection pipe 11 are on the same vertical straight line. The shape of the fixing frame 5 is "I"-shaped. A liquid storage tank 6 is fixedly arranged at the top of the fixing frame 5. An adding port 7 is fixedly arranged at the center position of the top of the liquid storage tank 6.

[0025] When using this lithium-ion battery liquid injection auxiliary device, first place the lithium-ion battery 12 to be injected with liquid inside the placement groove 13. Place the placement plate 4 on the outer end of the top of the moving plate 3 through the positioning rod and the positioning groove 9. The positioning rod is inserted into the positioning groove 9. Through the positioning rod and the positioning groove 9, the placement plate 4 can be limited in the horizontal direction. Start the servo motor.

An electromagnetic valve is provided on the liquid injection pipe 11. The electrolyte liquid is controlled by the electromagnetic valve to be injected into the lithium-ion battery 12 through the liquid storage tank 6 and the liquid injection pipe 11. During the liquid injection process, another placement plate 4 with a lithium-ion battery 12 is installed on the top of both ends of the moving plate 3. After the liquid injection is completed, the servo motor, the screw 16 and the slider 15 drive the moving plate 3 and the lithium-ion battery 12 to move in the reverse direction, and the lithium-ion battery 12 after the liquid injection is removed from the inside of the fixed frame 5. The lithium-ion battery 12 without liquid injection enters the inside of the fixed frame 5 and continues the liquid injection. The lithium-ion battery 12 after the liquid injection is taken out from the inside of the placement groove 13, and the lithium-ion battery 12 without liquid injection is continuously placed therein. The driving mechanism 2 drives the moving plate 3 and the placement plate 4 to reciprocate inside the fixed frame 5, which is convenient for alternately moving the lithium-ion battery 12 to the bottom of the liquid injection pipe 11 or removing it from the bottom of the liquid injection pipe 11. It is not necessary to take out each lithium-ion battery 12, which is convenient for batch liquid injection of the lithium-ion battery 12 and can improve the processing efficiency of the lithium-ion battery 12; the moving plate 3 can be limited by the action of the fixed rod 8 and the fixed block 10; the provided fixed frame 5 can also increase the safety during the liquid injection process and prevent the electrolyte liquid from splashing to both sides.
