Above the bottom plate 2 and on one side of the fixing plate 3, there is a side plate 4. Above the bottom plate 2 and on the side far from the side plate 4, there is a first mounting plate 6. On the side of the first mounting plate 6 far from the bottom plate 2, there is a first hydraulic cylinder 7. The stroke end of the first hydraulic cylinder 7 penetrates through the first mounting plate 6 and is fixedly connected to a pressing plate 8. When the first hydraulic cylinder 7 works, the first hydraulic cylinder 7 pushes the pressing plate 8 to move horizontally. Through the mutual cooperation between the pressing plate 8 and the side plate 4, the pre-press stacking table can stack and extrude the batteries. Above the workbench 1 and on the side far from the fixing plate 3, there is a second mounting plate 9. On the side of the second mounting plate 9 far from the bottom plate 2, there is a second hydraulic cylinder 10. The stroke end of the second hydraulic cylinder 10 penetrates through the second mounting plate 9 and is fixedly connected to a pushing plate 11. When the second hydraulic cylinder 10 works, the second hydraulic cylinder 10 pushes the pushing plate 11 to move horizontally. Through the mutual cooperation between the pushing plate 11 and the fixing plate 3, the sides of the batteries can be accurately aligned. At the upper end inside the workbench 1, there is a support plate 12. In the middle below the support plate 12, there is a third hydraulic cylinder 13. The stroke end of the third hydraulic cylinder 13 penetrates through the support plate 12 and is fixedly connected to a movable plate 14. Above the movable plate 14, there are a plurality of equally spaced limiting blocks 16. Through grooves 15 matching the limiting blocks 16 are formed on the workbench 1 and the bottom plate 2. When the third hydraulic cylinder 13 works, the third hydraulic cylinder 13 pushes the movable plate 14 to move vertically. Through the transmission of the movable plate 14, the limiting blocks 16 also move accordingly. During the upward movement of the limiting blocks 16, the upper ends of the limiting blocks 16 penetrate through the through grooves 15 and extend above the bottom plate 2. Thus, the batteries can be divided by the plurality of equally spaced limiting blocks 16, making it more convenient to place the PC board and the 3M glue between two batteries.

The third guide rods 20 are fixedly connected to the movable plate 14, and the third guide rods 20 are movably connected to the support plate 12. Through the mutual cooperation between the third guide rods 20 and the support plate 12, the moving stability of the movable plate 14 is effectively improved.
[0028] At the four corners under the workbench 1, support legs 21 are provided.
[0029] Specifically, in the present utility model, when stacking batteries, the batteries are sequentially placed between the limit blocks 16, and a PC board and 3M glue are placed between the batteries.
