A clamping plate 407 is fixedly connected to the top of each T-shaped slider 405. A positioning plate 402 is fixedly connected to the side of the top of the placement platform 401 near the vertical plate 3. The positioning mechanism 4 allows the battery to be positioned in the middle of the placement platform 401, facilitating its cooperation with the upper pressing mold 205.

[0024] In this embodiment, a first cylinder 301 is fixedly connected to the side of the vertical plate 3 away from the pneumatic pressing mechanism 2. The output end of the first cylinder 301 passes through the vertical plate 3 and is fixedly connected to one side of the placement platform 401. The first cylinder 301 is connected to the air pump through a pneumatic component. The battery is transported by extending and retracting the first cylinder 301.

[0025] In this embodiment, a rectangular groove 101 is provided on the top of the workbench 1 near the positioning mechanism 4. Sliding plates 5 are slidably provided at both ends of the rectangular groove 101. The top of the two sliding plates 5 is provided with irregular holes 501. The bottoms of the two sliding rods 406 are slidably connected in the adjacent irregular holes 501. A moving block 502 is fixedly connected to the middle of the bottom of the two sliding plates 5. A strip hole adapted to the two moving blocks 502 is provided at the middle of the bottom of the rectangular groove 101.

[0026] In this embodiment, the bottom of the workbench 1 is fixedly connected to both ends of the rectangular groove 101 with fixed plates 6. A bidirectional lead screw 7 is rotatably connected between the two fixed plates 6, and the two ends of the bidirectional lead screw 7 are threaded through adjacent moving blocks 502. Both moving blocks 502 are fixedly fitted with lead screw nuts that are compatible with the bidirectional lead screw 7. One end of the bidirectional lead screw 7 is fixedly connected to a handwheel 701 through adjacent fixed plates 6. The fixed plate 6 on this side has a round hole that is compatible with the bidirectional lead screw 7. By rotating the handwheel 701, the initial position of the two sliding plates 5 is adjusted, thereby adjusting the positioning mechanism 4.

[0027] In this embodiment, each of the two irregular holes 501 includes an oblique hole and two straight holes, and the two ends of the oblique hole are respectively connected to the straight holes. The irregular holes 501 are designed to bring the two clamping plates 407 closer to each other, so as to position the battery in the middle of the placement platform 401 without moving it.

[0028] In this embodiment, the pneumatic pressing mechanism 2 includes four guide rods 202 fixedly connected to both sides of one end of the top of the workbench 1. The top of the four guide rods 202 is fixedly connected to the same top plate 201. A second cylinder 204 is fixedly connected to the middle of the top of the top plate 201, and the second cylinder 204 is connected to the air pump through a starting component.

[0029] In this embodiment, the pneumatic pressing mechanism 2 also includes a pressure plate 203 that is slidably sleeved on the circumferential surface of the four guide rods 202. The pressure plate 203 has round holes at the four corners that are adapted to the guide rods 202. The bottom output end of the second cylinder 204 passes through the top plate 201 and is fixedly connected to the top of the pressure plate 203. The bottom of the pressure plate 203 is fixedly connected to the upper pressing mold 205 by bolts. The bolts facilitate the replacement of different upper pressing molds 205.

[0030] Working principle: During use, the battery to be repaired is placed on the placement platform 401, ensuring it is in contact with the positioning plate 402. The first cylinder 301 is activated, pushing the positioning mechanism 4 closer to the pneumatic pressing mechanism 2. During this process, the slide rod 406 slides through the irregular hole 501, causing the two clamping plates 407 to gradually approach, clamping and positioning the battery in the center. When the placement platform 401, carrying the battery, reaches the bottom of the pneumatic pressing mechanism 2, the second cylinder 204 is activated, causing the pressure plate 203 to descend along with the upper mold 205, thus achieving the desired pressure. The battery pressing is controlled by the second cylinder 204 to prevent the battery from being over-compressed. When pressing different battery casings, the initial position of the two sliding plates 5 is adjusted by turning the handwheel 701, which in turn adjusts the initial position of the two clamping plates 407, making it easier to fix batteries of different sizes. At the same time, the upper pressing mold 205 can be replaced by bolts. With the above settings, the user only needs to place the battery between the two clamping plates 407 and close it to the positioning plate 402 during the process, without much manual operation.
