[0038] Next, the working principle of this embodiment is described:

[0039] Before formation, a blade cell a is placed between the long side positioning plate 5 and the backing plate 6, with the two ends of the blade cell a in the length direction facing the two short side positioning plates 7 respectively, and the two wide surfaces of the cell facing the long side positioning plate 5 and the backing plate 6 respectively. At the same time, the liquid injection hole of the cell is placed above the liquid receiving box 8, and the structural design of the bottom plate 1 can realize the preliminary positioning of the cell a;

[0040] By rotating the rotating rod 23 of the two screw rod assemblies 1, the screw rod 20 is driven to rotate, thereby driving the end pressure plate 2 to move through the connecting seat 19, so that the two end pressure plates 2 are close to the battery cell; after moving a predetermined distance, the probes 4 of the two end pressure plates 2 are respectively in contact with the positive pole and the negative pole at both ends of the battery cell a; a plurality of vacuum suction cups 38 are respectively adsorbed on a plurality of battery cells and the vacuum suction cups 38 are connected to the injection holes of the battery cells;

[0041] By rotating the rotating rod 2 30 of the two screw rod assemblies 2, the screw rod 27 is driven to rotate, thereby driving the side pressure plate 3 to move through the connecting seat 26, so that the two side pressure plates 3 are close to the battery cell a; after moving a predetermined distance, the insulating plates 33 of the two side pressure plates 3 are in contact with the battery cell a;

[0042] The vacuum equipment is connected to the vacuum air pressure relief valve 40 through a pipeline, the suction force is adjusted through the vacuum air pressure relief valve 40, each valve 37 is opened, and the vacuum equipment is started to vacuum the multiple battery cells a. Since the liquid storage cylinder 34 has a storage function, the electrolyte inside the battery cell a flows to the vacuum suction cup 38 through the liquid injection hole under the vacuum suction force, and then flows into the vacuum pumping tube 35 and flows from the vacuum pumping tube into the corresponding liquid storage cylinder 34 for storage. Most of the sucked electrolyte is stored in the liquid storage cylinder 34 to prevent the electrolyte of the battery cell a from being sucked away completely; the probes 4 on the two end pressure plates 2 are connected to electricity for charging and formation. When the battery cell a is formed, the generated gas can be sucked away along the vacuum suction cup 38, the vacuum pumping tube 35, the liquid storage cylinder 34, and the manifold 36;

[0043] When the formation is completed, the vacuum is turned off, and the electrolyte in the liquid collection cylinder 34 can flow back to the inside of the battery cell a along the pipeline due to gravity; by rotating the rotating rod 23 of the two screw rod assemblies 1, the screw rod 20 is driven to rotate, thereby driving the end pressure plate 2 to move through the connecting seat 19, so that the two end pressure plates 2 are separated from the battery cell, the vacuum suction cup 38 is separated from the battery cell a, and the electrolyte remaining at the injection hole will fall into the liquid receiving box 8 for collection; by rotating the rotating rod 2 30 of the two screw rod assemblies 2, the screw rod 27 is driven to rotate, thereby driving the side pressure plate 3 to move through the connecting seat 2 26, so that the two side pressure plates 3 are away from the battery cell a, and the battery cell that has been formed can be taken away.

[0044] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component.
