Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery technology, and in particular to a rapid assembly device for lithium-ion battery packs. Background Technology

[0002] A lithium-ion battery pack is a battery system formed by connecting multiple lithium-ion batteries together in a specific way. Lithium-ion battery packs typically consist of multiple individual lithium-ion batteries connected in series or parallel to provide higher voltage, capacity, or current output capabilities. Lithium-ion battery packs have advantages such as high energy density, lightweight design, and long lifespan, and are therefore widely used in various fields, including electric vehicles, energy storage systems, and portable devices.

[0003] Before connecting multiple individual lithium batteries together, they need to be arranged and fixed neatly and evenly to ensure that they do not short-circuit or collide. Generally, to facilitate a stable electrical connection between multiple individual lithium batteries, two connecting brackets are used to hold them in place. The secured batteries then form a single unit, making it easier to connect them and subsequently pack and seal them.

[0004] When assembling and fixing multiple individual lithium batteries using connecting brackets, the insertion of multiple individual lithium batteries is done manually. Workers usually align the individual lithium batteries with the insertion holes on the lower connecting bracket and insert them one by one. After the lower connecting bracket is filled, the upper connecting bracket, which is set to fit, is then placed on the top of the entire lithium battery pack. This step takes a long time, resulting in low assembly efficiency of the lithium battery pack. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1 to 3This utility model provides a rapid assembly device for lithium-ion battery packs, comprising a base 1, a conveyor on the top surface of the base 1, two support plates 3 symmetrically fixed on one side of the top surface of the base 1, a flip plate 4 movably connected to the top surface of each of the two support plates 3, an clearance groove on the outside of the support plate 3, a flipping block rotatably connected within the clearance groove, the flipping block being fixed to the bottom surface of the flip plate 4, a rotating shaft 18 fixedly sleeved on the side of the flipping block, the rotating shaft 18 being rotatably connected within the clearance groove, and a drive motor 5 horizontally fixed on the side of the support plate 3, the output end of the drive motor 5 being drively connected to one end of the rotating shaft 18. The inner side of the flap 4 is provided with a support block 8, and the outer side of the flap 4 is horizontally fixed with a cylinder 2. The output end of the cylinder 2 moves through the flap 4 and is horizontally fixed with the support block 8. The support block 8 is provided with a groove 9, and the groove 9 is provided with a support frame 10. The side of the support frame 10 is horizontally opened with multiple equally spaced sleeve holes. The sleeve holes are fixedly connected with a limiting ring. The groove 9 is provided with a clamping member that fits with the support frame 10. The groove 9 is embedded with an infrared sensor 17. The infrared sensor 17 is located at the outlet end of the conveyor, and the center of the infrared sensor 17 is concentric with the center of the rightmost sleeve hole of the support frame 10.

[0022] The inner side of the flap 4 is horizontally symmetrically provided with two blind holes. Each blind hole has two horizontally opened sliding grooves. Each sliding groove is slidably connected to a slider. The two sliders are fixed together by a guide rod. The guide rod is movably connected in the blind hole and fixedly connected to the support block 8.

[0023] The clamping component includes two horizontally symmetrical clamping plates 14 arranged in the groove 9. The clamping plates 14 are in contact with the outside of the support frame 10. An electric push rod 13 is fixed to the outside of each clamping plate 14. The electric push rod 13 is fixed in the groove 9. Two vertically symmetrical clamping plates 16 are arranged in the groove 9. The two clamping plates 16 are in contact with the outside of the support frame 10. An electric push rod 15 is vertically fixed to the end of each clamping plate 16. The electric push rod 15 is fixed in the groove 9.

[0024] The conveyor includes multiple support legs 6 fixed to the top surface of the base 1. The top surfaces of the multiple support legs 6 are jointly fixed to a U-shaped plate 7. A conveyor belt 11 is provided inside the U-shaped plate 7. Multiple arc-shaped grooves 12 are provided at equal intervals on the outer edge of the conveyor belt 11. The lower edge of the arc-shaped grooves 12 is higher than the top surface of the U-shaped plate 7. The width of the U-shaped plate 7 is less than the length of the lithium battery.

[0025] The upper and lower support frames 10 of the lithium battery are respectively placed in the grooves 9 inside the two support blocks 8 and fixed by clamping components. The cylinder 2 drives the two support blocks 8 to move towards both sides of the lithium battery. The support blocks 8 drive the two support frames 10 to move towards both ends of the lithium battery, realizing the automatic assembly of the lithium battery. This allows the two support frames 10 of the lithium battery to be assembled simultaneously, eliminating the need for manual assembly of the lithium battery and battery bracket. It also eliminates the need to install the two support frames 10 on the lithium battery in two separate steps, thereby improving the assembly efficiency of the lithium battery pack.

[0026] Working principle: During use, the drive motor 5 drives the rotating shaft 18 to rotate, which in turn drives the flip plate 4 to flip outward, making the flip plate 4 horizontal. Then, the two support frames 10 of the lithium battery are respectively installed in the grooves 9 of the two support blocks 8. Then, the electric push rod 13 and the electric push rod 2 15 drive the clamping plates 14 and 2 16 to move relative to each other, fixing the support frame 10 in a centered position. Then, the drive motor 5 drives the flip plate 4 to flip upward, making the flip plate 4 vertical. Then, multiple individual lithium batteries are placed horizontally in the arc-shaped groove 12 on the conveyor belt 11. The conveyor belt 11 delivers multiple individual lithium batteries between the two support blocks 8. When the center of the lithium battery in the rightmost arc-shaped groove 12 is aligned with the infrared sensor 17, the infrared sensor 17 detects it, and the conveyor belt 11 stops. Then, cylinder 2 drives two support blocks 8 to move relative to each other. Support blocks 8 drive two support frames 10 to move towards both ends of the lithium battery, so that the lithium battery is fitted into the sleeve hole in the support frame 10. Then, electric push rod 13 and electric push rod 25 drive clamping plate 14 and clamping plate 2 to move in opposite directions, so that clamping plate 14 and clamping plate 2 and the support frame 10 with lithium battery installed are separated. Then, cylinder 2 drives support block 8 to return to the inside of flip plate 4. At the same time, drive motor 5 drives flip plate 4 to flip downward, so that flip plate 4 is in a horizontal state. Then, the support frame 10 is placed into the groove 9 of support block 8. Then, clamping plate 14 and clamping plate 2 fix the support frame 10. At the same time, the assembled lithium battery will be sent out by conveyor belt 11. Then flip plate 4 flips again, so that flip plate 4 returns to a vertical state, and the second batch of lithium batteries is assembled.
