[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figures 1 to 6As shown, this utility model provides a lithium-ion battery repair device, including a repair platform 1. Side plates 12 are fixedly connected to the left and right sides of the upper surface of the repair platform 1. An L-shaped rod 2 is movably sleeved on the outer surface of the side plate 12. The inner end of the L-shaped rod 2 passes through the side plate 12 and extends to the inner side of the side plate 12 and is fixedly connected to a clamping plate 3. A fixed shaft 4 is fixedly connected to the middle of the lower surface of the repair platform 1. A rotating rod 5 is movably sleeved on the outer surface of the fixed shaft 4. A sliding groove 6 is opened on the rear side of the lower surface of the rotating rod 5. Both ends of the rotating rod 5 are hinged to connecting rods 7. The other end of the connecting rod 7 is hinged to the bottom end of the L-shaped rod 2. A first air cylinder 8 located behind the rotating rod 5 is fixedly installed on the lower surface of the repair platform 1. A connecting block 9 is fixedly connected to the other end of the first air cylinder 8. A round block 10 is fixedly sleeved on the inner surface of the connecting block 9. The outer surface of the round block 10 is movably connected to the inner surface of the sliding groove 6.

[0024] When the operator starts the first pneumatic cylinder 8, the connecting block 9 and the round block 10 will start to move to the right. As the round block 10 moves, the rotating rod 5 will start to rotate around the fixed shaft 4 under the drive of the round block 10. At this time, the connecting rod 7 will start to rotate under the drive of the rotating rod 5, and the other end of the connecting rod 7 will drive the L-shaped rod 2, so that the L-shaped rod 2 and the clamping plate 3 will start to move towards each other as a whole.

[0025] The lower surface of the repair table 1 is fixedly connected with four support legs 11, all of which are the same size.

[0026] The design of the support leg 11 serves to support the entire repair table 1.

[0027] The upper surface of the side plate 12 is fixedly connected to the mounting plate 13, and the upper surface of the mounting plate 13 is fixedly installed with the second pneumatic cylinder 26. The bottom end of the second pneumatic cylinder 26 passes through the mounting plate 13 and extends to the bottom of the mounting plate 13 and is fixedly connected to the hollow box 14.

[0028] The operation of the second pneumatic cylinder 26 will cause the hollow box 14 to begin to move downwards.

[0029] The hollow box 14 has a cover plate 15 fixedly connected to its lower surface, a drive motor 24 fixedly installed on its right surface, a threaded rod 25 fixedly sleeved at the other end of the output shaft of the drive motor 24, the other end of the threaded rod 25 passing through the hollow box 14 and extending to the left side of the hollow box 14, and a second toothed plate 19 located inside the hollow box 14 threadedly sleeved on the outer surface of the threaded rod 25, the outer surface of the second toothed plate 19 being movably connected to the inner surface of the hollow box 14.

[0030] When the drive motor 24 starts running, the threaded rod 25 will begin to rotate.

[0031] Among them, a cylinder 16 is fixedly connected to the middle of the upper surface of the cover plate 15, the top of the cylinder 16 is fixedly connected to the top of the inner surface of the hollow box 14, and a gear 17 is movably sleeved on the outer surface of the cylinder 16, and the outer surface of the gear 17 is meshed with the outer surface of the second tooth plate 19.

[0032] The movement of the second gear plate 19 will drive the gear 17, causing the gear 17 to start rotating around the cylinder 16 as the axis.

[0033] Among them, a first toothed plate 18 is movably connected to the front side of the inner surface of the hollow box 14. The outer surface of the first toothed plate 18 is meshed with the outer surface of the gear 17. Connecting plates 20 are movably connected to both sides of the inner surface of the cover plate 15. There are two connecting plates 20. The top of the two connecting plates 20 penetrates the cover plate 15 and extends into the interior of the hollow box 14 and is fixedly connected to the lower surface of the first toothed plate 18 and the second toothed plate 19, respectively. Insert rods 21 are fixedly connected to the outer surface of the two connecting plates 20.

[0034] The design of the cover plate 15 allows the two connecting plates 20 to move in opposite directions along the inner surface of the cover plate 15.

[0035] Among them, the outer surface of the insertion rod 21 is movably sleeved with a sleeve block 22, the upper surface of the sleeve block 22 is movably connected to the lower surface of the cover plate 15, and the lower surface of the sleeve block 22 is fixedly connected with a pressure plate 23.

[0036] The design of the pressure plate 23 serves to compress the outer surface of the lithium battery, thereby repairing the bulge on the outer surface of the lithium battery.

[0037] Working principle and usage process of the utility model:

[0038] First, the operator places the lithium battery under the pressure plate 23 and starts the first pneumatic cylinder 8. As the first pneumatic cylinder 8 operates, the connecting block 9 and the round block 10 begin to move. The movement of the round block 10 drives the rotating rod 5, causing the rotating rod 5 to rotate around the fixed shaft 4. At the same time, the connecting rod 7 will start to rotate under the drive of the rotating rod 5. The other end of the connecting rod 7 will drive the L-shaped rod 2, causing the L-shaped rod 2 and the clamping plate 3 to move towards each other. Finally, the two clamping plates 3 will contact the outer surface of the lithium battery, and the lithium battery will be fixed above the repair table 1. Then, the operator starts the second pneumatic cylinder 26. As the second pneumatic cylinder 26 operates, the hollow box 14 and the pressure plate 23 will begin to move downward. Finally, the bulge of the lithium battery will be flattened by the pressure plate 23.

[0039] When the operator needs to replace the pressure plate 23, the operator starts the drive motor 24. As the drive motor 24 runs, the threaded rod 25 will rotate, which will cause the second toothed plate 19 to move to the left under the drive of the threaded rod 25. The movement of the second toothed plate 19 will drive the gear 17 to rotate. At the same time, the first toothed plate 18 will also move to the right as the gear 17 rotates. Finally, the two connecting plates 20 will disengage from the inner surface of the sleeve block 22. At this time, the fixing of the sleeve block 22 and the pressure plate 23 will be released, and the operator can then remove the pressure plate 23 and replace it.
