[0048] Specifically, after the battery top side sealing mechanism 1 completes the side sealing of the soft-pack battery, a human or robotic arm transfers the soft-pack battery from the clamping component 15 to the clamp 25. The first driving member 21 drives the cover plate 22 toward the box 23 until the clamp 25 and the soft-pack battery thereon are located within the internal space 231 of the box 23. The cover plate 22 seals the opening 232 of the box 23. The liquid injection component 24 injects electrolyte into the soft-pack battery, and the bag sealing component 26 seals the bag opening of the soft-pack battery. In the present invention, during the process of the liquid injection component 24 injecting electrolyte into the soft-pack battery and the bag sealing component 26 sealing the bag opening of the soft-pack battery, the soft-pack battery is in the enclosed internal space 231, thereby preventing interference from the external environment on the liquid injection process of the soft-pack battery and ensuring the quality of the soft-pack battery.

[0049] The first driving member 21 drives the cover plate 22 to move toward the end away from the box body 23 until the clamp 25 and the soft-pack battery thereon are removed from the internal space 231, thereby facilitating manual removal of the soft-pack battery from the clamp 25 by a human or robot. The battery filling mechanism 2 has a compact structure and occupies little space.

[0050] In one embodiment, if Figure 3 and Figure 4 As shown, the battery filling mechanism 2 also includes a bag opening component 27, and the bag opening component 27 includes a second driving member 271 and a suction cup 272; the suction cup 272 is installed at the output end of the second driving member 271; the second driving member 271 is used to drive the suction cup 272 to move so that the suction cup 272 opens the bag opening of the soft-pack battery.

[0051] The second driving component 271 includes but is not limited to a pneumatic cylinder, a hydraulic cylinder, a linear motor, etc.

[0052] Specifically, the second driving member 271 drives the suction cup 272 to move toward the end close to the soft-pack battery until the suction cup 272 sucks the outer wall of the soft-pack battery; the second driving member 271 then drives the suction cup 272 to move toward the end away from the soft-pack battery until the suction cup 272 opens the bag opening of the soft-pack battery; after the bag opening of the soft-pack battery is opened by the bag opening member 27, the first driving member 21 moves the clamp 25 and the soft-pack battery thereon into the internal space 231 through the cover plate 22.

[0053] In this embodiment, the design of the bag opening component 27 ensures the stability and smoothness of the liquid injection component 24 extending into the soft-pack battery.

[0054] In one embodiment, if Figure 4 As shown, the bag sealing component 26 includes a bag sealing drive component 261, a first heat sealing plate 262 and a second heat sealing plate 263; the bag sealing drive component 261 is connected to the first heat sealing plate 262 and the second heat sealing plate 263, and is used to drive the first heat sealing plate 262 and the second heat sealing plate 263 to clamp and seal the bag opening of the soft-pack battery.

[0055] The bag sealing drive assembly 261 includes, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, and a screw-nut assembly. The first and second heat sealing plates 262 and 263 are both integrated with heating wires and heating blocks. When powered on, the first and second heat sealing plates 262 and 263 heat up and seal the soft-pack batteries.

[0056] In this embodiment, the bag sealing drive assembly 261 drives the first and second heat sealing plates 262, 263 to clamp the opening of the soft-pack battery bag. When powered, the first and second heat sealing plates 262, 263 heat up and complete the sealing of the soft-pack battery. In this embodiment, the bag sealing component 26 has a simple structure and low manufacturing cost.

[0057] In one embodiment, if Figure 1 As shown, the box body 23 is also provided with a vacuum interface (not shown in the figure) for connecting to a vacuum extraction device.

[0058] The vacuum pumping device includes but is not limited to a vacuum pump, etc.; the vacuum pumping device can be a part of the battery liquid injection mechanism 2 or an external component.

[0059] Specifically, the fixture 25 and the soft-pack battery thereon are positioned within the internal space 231. After the cover 22 covers the opening 232, the vacuum pump evacuates the internal space 231 to a vacuum state, and the injection assembly then injects electrolyte into the soft-pack battery. In this embodiment, the battery injection mechanism 2 can complete the injection function of soft-pack batteries in a vacuum environment, improving the applicability and versatility of the battery injection mechanism 2.
