[0002] Lithium-ion batteries, as the core power source for modern portable electronic devices and electric vehicles, are becoming increasingly important. With their high energy density, low self-discharge rate and relatively long lifespan, they have rapidly replaced traditional nickel-cadmium and nickel-metal hydride batteries. Lithium-ion battery packs are a key component in the application of lithium-ion batteries. They are not simply stacked cells, but a complex system that integrates cell management, structural support, electrical connection and safety protection.

Therefore, after the lithium battery pack is assembled, it must be transferred to an independent testing area for testing. The transfer process has potential safety risks and can easily affect the finished quality and stability of the lithium battery pack, thereby reducing the efficiency and reliability of assembly and testing. To solve the above problems, we propose a lithium battery pack assembly and testing device. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-4As shown, in this embodiment, a lithium battery PACK assembly and testing device includes a vertical plate 1. A bracket 4 is slidably connected to one side of the vertical plate 1. A lifting assembly is provided on one side of the vertical plate 1, which is used to move the bracket 4. A power supply device 5 is provided on the top of the bracket 4, and the output end of the power supply device 5 extends to the bottom of the bracket 4. A temperature sensor 22 is provided on the bottom of the bracket 4. Two clamping blocks 14 are slidably connected to one side of the vertical plate 1. A clamping assembly is provided on one side of the vertical plate 1, which is used to move the two clamping blocks 14. A limit plate 15 is fixedly connected to one side of each of the two clamping blocks 14. A movable plate 17 is slidably connected to one side of each of the two clamping blocks 14. A liquid storage tank 2 is fixedly connected to one side of the vertical plate 1. A liquid injection port 3 is opened on the top of the liquid storage tank 2. Two industrial cameras 6 and Two fire nozzles 7 and two clamping blocks 14 each have a guide groove 16 on one side. Guide blocks 24 are slidably connected between the inner walls of the two guide grooves 16. One side of each guide block 24 is fixedly connected to two movable plates 17. Telescopic electric cylinders 18 are fixedly installed on one side of each clamping block 14. The output ends of the two telescopic electric cylinders 18 extend into the interior of the two guide grooves 16 and are fixedly connected to the two guide blocks 24. Two connecting pipes 19 are fixedly connected between the upright plate 1 and the liquid storage tank 2. One end of each connecting pipe 19 passes through the upright plate 1 and is fixedly connected to the two fire nozzles 7. The bottom ends of each connecting pipe 19 extend into the interior of the liquid storage tank 2. Two water pumps 20 are fixedly installed between the inner walls of the liquid storage tank 2. The output ends of each water pump 20 are fixedly connected to the extension ends of the two connecting pipes 19.

[0024] During the assembly and testing of the lithium battery pack, multiple lithium batteries are first placed between two clamping blocks 14. Then, the device is connected to an external power source and powered on. The controller then activates two telescopic cylinders 18, which push two guide blocks 24 to move between the inner walls of two guide grooves 16, thereby driving two movable plates 17 to move. With the help of two limiting plates 15, this ensures that the multiple lithium batteries fit tightly together. At the same time, the clamping assembly drives the two clamping blocks 14 to move on one side of the upright plate 1, thereby further clamping the multiple lithium batteries to facilitate the assembly of multiple lithium batteries into a lithium battery pack. Then, two industrial cameras 6 are used to detect various defects on the exterior of the lithium battery pack. Subsequently, the lifting assembly drives the bracket 4 to move on one side of the upright plate 1, and the lithium battery pack is charged and discharged through the power supply device 5 to accelerate the aging of the lithium battery pack. Meanwhile, the temperature sensor 22 monitors the temperature of the lithium battery pack in real time during the aging process.

[0025] When a fire occurs during the assembly or testing of a lithium battery pack, cooling water is injected into the storage tank 2 through the injection port 3. Then, the cooling water is sent to the two connecting pipes 19 by two water pumps 20. Finally, the fire is extinguished by two fire nozzles 7, thereby improving the effect of lithium battery pack assembly and testing.

A threaded rod 9 is rotatably connected between the inner walls of the lifting groove 8. A lifting block 21 is threadedly connected to the outer side of the threaded rod 9. One side of the lifting block 21 is fixedly connected to the bracket 4. A lifting motor 10 is fixedly installed on the top of the upright plate 1. The output end of the lifting motor 10 extends into the interior of the lifting groove 8 and is fixedly connected to the threaded rod 9.

[0027] The lifting motor 10 drives the threaded rod 9 to rotate between the inner walls of the lifting groove 8, while simultaneously driving the lifting block 21 to move the bracket 4 on one side of the upright plate 1, thereby improving the ease of use of the lithium battery PACK assembly and testing device.

[0028] like Figures 1-4 As shown, the clamping assembly includes a clamping groove 11, which is formed on one side of the upright plate 1. A bidirectional lead screw 12 is rotatably connected between the inner walls of the clamping groove 11. Two sliders 23 are threadedly connected to the outer side of the bidirectional lead screw 12.

The output end of the clamping motor 13 extends into the interior of the clamping groove 11 and is fixedly connected to the bidirectional lead screw 12.

[0029] The clamping motor 13 drives the bidirectional lead screw 12 to rotate between the inner walls of the clamping groove 11, and drives the two sliders 23 to move the two clamping blocks 14 on one side of the upright plate 1, thereby improving the stability of lithium battery PACK assembly and testing.

[0030] This utility model provides a lithium battery PACK assembly and testing device. The specific working principle is as follows: During the assembly and testing of the lithium battery PACK, multiple lithium batteries are first placed between two clamping blocks 14. Then, the device is connected to an external power source and powered on. Next, the controller activates two telescopic cylinders 18, which push two guide blocks 24 to move between the inner walls of two guide grooves 16, thereby driving two movable plates 17 to move. Combined with two limiting plates 15, this ensures that the multiple lithium batteries are tightly fitted together. Simultaneously, the clamping motor 13 drives the bidirectional lead screw 12 to rotate between the inner walls of the clamping groove 11, thus driving... Two sliders 23 drive two clamping blocks 14 to move on one side of the upright plate 1, thereby further clamping multiple lithium batteries to facilitate the assembly of multiple lithium batteries into a lithium battery PACK. Then, two industrial cameras 6 are used to detect various defects on the exterior of the lithium battery PACK. Subsequently, the lifting motor 10 drives the threaded rod 9 to rotate between the inner walls of the lifting groove 8, while simultaneously driving the lifting block 21 to move the bracket 4 on one side of the upright plate 1. The lithium battery PACK is charged and discharged through the power supply device 5, thereby accelerating the aging of the lithium battery PACK. At the same time, the temperature sensor 22 monitors the temperature of the lithium battery PACK in real time during the aging process.

[0031] When a fire occurs during the assembly or testing of a lithium battery pack, cooling water is injected into the storage tank 2 through the injection port 3. Then, the cooling water is sent to the two connecting pipes 19 by two water pumps 20. Finally, the fire is extinguished by two fire nozzles 7, thus completing the use of the lithium battery pack assembly and testing device.
