Description

Technical Field

[0001] The present disclosure relates to the field of battery formation equipment, and in particular to a battery clamp and a high-temperature formation device. Background Art

[0002] With the rapid development of the soft-pack battery industry, the types of battery fixtures used for chemical composition and capacity are also increasing. At present, most of the fixtures on the market are used in manual production lines. Manual opening and material removal are cumbersome and inconvenient. Therefore, in the formation process of electronic cigarettes, it is very important to realize the automatic opening of battery fixtures. Such automated operation can not only improve production efficiency and reduce labor costs, but also bring higher stability and consistency to production. Through automated opening, the impact of human factors on the production process can be reduced, and product quality and production safety can be improved. Therefore, promoting the automation upgrade of battery fixtures is an important trend in the current development of the soft-pack battery industry.

[0003] After searching, it can be known that in the prior art, for example, patent CN202311245838.2 discloses a ternary soft-pack lithium-ion battery clamping device, including: a plate adjustment block, a force baffle and M sliding plates, M is an integer greater than 1; when M is equal to 2, the two sliding plates are parallel to each other, the force baffle is fixed on the side close to the plate adjustment block, and abuts against the outer surface of the plate adjustment block; N movable clamps are arranged on the sliding plate, N is an integer greater than 2, each movable clamp is correspondingly provided with a fixed clamp, there is only one fixed clamp close to the force baffle, and the movable clamp is parallel to the fixed clamp, which effectively achieves the clamping of the positive and negative pole ears of multiple ternary soft-pack lithium batteries, and is suitable for clamping the positive and negative pole ears of ternary soft-pack lithium batteries of different sizes, and keeps the clamping firm to prevent the ternary soft-pack lithium battery from falling or the contact surface between the ear and the metal contact sheet from loosening and affecting the subsequent capacity division process. The above-mentioned ternary soft-pack lithium-ion battery clamping device still has the following defects in practical application:

[0004] First, by adjusting the movable clamp and the fixed clamp, the positive and negative pole tabs of multiple ternary soft-pack lithium batteries can be clamped, and it is suitable for clamping the positive and negative pole tabs of ternary soft-pack lithium batteries of different sizes. However, it can only be applied to positive and negative pole tabs of different sizes. If the overall size of the battery is too large or too small, it cannot be clamped effectively, and additional adjustment or replacement of parts is required. Therefore, it cannot be applied to batteries with different overall sizes.

[0005] Second, the positive and negative pole tabs of the ternary soft-pack lithium battery are placed on two sliding plates respectively, so that the movable clamp and the fixed clamp clamp the pole tabs. The clamping device only clamps the pole tabs of the battery, and does not clamp other parts such as the battery cell. This cannot provide sufficient stability and may move or tilt during operation or transportation, resulting in poor contact or disconnection between the pole tab and the clamping device; and only clamping the pole tab may cause the pole tab to be over-stretched, twisted or compressed during operation, thereby damaging the pole tab structure or affecting its conductive performance.

[0048] Each clamping assembly includes two clamping mechanisms 30 that are arranged in parallel and opposite to each other. There is a certain distance between the two clamping mechanisms 30 in the same group, and at least one clamping mechanism 30 can move away from or close to the other clamping mechanism 30 on the pallet 10 to increase or decrease the distance between the two clamping mechanisms 30; the clamping mechanisms 30 are arranged along the width direction of the pallet 10, that is, the clamping mechanisms 30 are parallel to the width direction of the pallet 10, and there is a certain distance between the two clamping mechanisms 30 in the same group in the length direction of the pallet 10, and at least one of the two clamping mechanisms 30 in the same group can slide along the length direction of the pallet 10 to approach or move away from the other clamping mechanism 30;

[0056] Furthermore, in this embodiment, the clamping mechanism 30 further includes a bottom plate 304, the fixed member 301 is fixedly connected to the bottom plate 304, the movable member 302 is slidably connected to the bottom plate 304, and the bottom plate 304 is provided with a first transmission mechanism 60 on both sides of the fixed member 301, and the first transmission mechanisms 60 on both sides are connected to the movable member 302 to guide the movement of the movable member 302;

[0057] The first transmission mechanism 60 adopts gear and rack transmission, and is provided with a first rack, a second rack and a gear. The first rack is connected to the base plate 304, and the second rack is connected to one side of the fixed member 301. The upper teeth and the lower teeth of the gear are respectively meshed with the second rack and the first rack to form a meshing transmission. The first transmission mechanism 60 located on both sides of the fixed member 301 has the same structure and the direction of the meshing transmission is also consistent; the gears on both sides are rotatably connected by a rotating shaft, and the rotating shaft is rotatably penetrated through the movable member 302, so that the movement direction of the movable member 302 will not be offset.

[0058] Furthermore, in this embodiment, a plurality of assembly clamp components are arranged on the pallet 10 at intervals along the length direction and / or width direction of the pallet 10;

[0059] The fixed member 301 and the movable member 302 respectively have a fixed extension portion 3011 and a movable extension portion 3021 extending upwards, and a clamping area is provided between a single fixed extension portion 3011 and a single movable extension portion 3021 for clamping a battery tab, and a plurality of fixed extension portions 3011 and a plurality of movable extension portions 3021 are arranged alternately along the moving direction of the movable member 302 to form a plurality of clamping areas, and the clamping areas of the two clamping mechanisms 30 of the same group correspond to each other one by one; copper sheets are provided on both the fixed extension portion 3011 and the movable extension portion 3021 for contacting with the battery tab to form a closed loop;

[0060] A plurality of fixed extension portions 3011 and a plurality of movable extension portions 3021 are arranged in a staggered manner along the moving direction of the movable member 302, that is, one movable extension portion 3021, one fixed extension portion 3011, one movable extension portion 3021, one fixed extension portion 3011, and so on are arranged in a staggered manner, and a clamping area is formed between one movable extension portion 3021 and the next fixed extension portion 3011;

[0061] Through the above structure, a single battery clamp can clamp multiple batteries 50 at the same time, so that multiple batteries 50 can be processed simultaneously during work, thereby greatly improving efficiency; compared to production lines that require frequent replacement or adjustment of clamps to adapt to batteries 50 of different sizes and specifications, a battery clamp of this structure allows workers to use only one to continuously process multiple batteries 50, reducing operating steps and potential errors; and by centrally using the same battery clamp, it can be ensured that all batteries 50 are subjected to consistent clamping force and precision during the processing process, thereby improving the consistency of product quality.

[0062] Furthermore, in this embodiment, the driving assembly 20 includes a power mechanism, a limiting mechanism 201 and a pushing mechanism 202; the power mechanism can be a driving motor or a hydraulic cylinder, etc.;

[0063] The end of the pushing mechanism 202 close to the edge of the tray 10 has a first convex structure 2021 extending outward, and the first convex structure 2021 is connected to the output end of the power mechanism. The pushing mechanism 202 moves on the tray 10 close to the movable member 302 through the drive of the power mechanism.

[0064] The first convex structure 2021 has a first through hole in the middle thereof adapted to the limiting mechanism 201. The first through hole is an open structure on the side away from the tray 10. One end of the limiting mechanism 201 is provided with the first through hole and is slidably connected to the first convex structure 2021. The other end of the limiting mechanism 201 is connected to the tray 10. The limiting mechanism 201 is used to limit the movement distance of the pushing mechanism 202 on the tray 10.

[0065] The limiting mechanism 201 includes a bearing support and bearings rotatably connected at both ends of the bearing support. The bearings are externally threaded bearings. The externally threaded bearings at both ends abut against the upper surface of the first convex structure 2021. When there is no driving force or elastic force acting on the pushing mechanism 202, the abutment of the externally threaded bearings will limit the movement of the pushing mechanism 202, and the first through hole abuts against the bearing support away from the side with the opening structure, which can prevent the pushing mechanism 202 from sliding out of the tray 10.

[0066] Further, in this embodiment, the pushing mechanism 202 includes a first push plate 2022, a second push plate 2023 and a plurality of push rods 2024, the first push plate 2022 and the second push plate 2023 are respectively connected to the two ends of the push rods 2024, and the plurality of push rods 2024 are arranged at intervals along the length direction of the tray 10, and the first push plate 2022 and the second push plate 2023 are respectively used to push the movable member 302 at the corresponding position; the first push plate 2022 and the second push plate 2023 are both parallel to the length direction of the tray 10;

[0067] The distance between each two adjacent push rods 2024 is greater than the distance between the two clamping mechanisms 30, and the length of the push rods 2024 is greater than the length of the clamping mechanism 30; that is, multiple groups of clamping components can be placed along the length direction of the pallet 10 between the first push plate 2022 and the second push plate 2023, and all of them are pushed by the first push plate 2022. Multiple groups of clamping components can be placed along the length direction of the pallet 10 outside the side of the second push plate 2023 away from the first push plate 2022, and all of them are pushed by the second push plate 2023.

[0068] Furthermore, in this embodiment, the bottoms of the first push plate 2022 and the second push plate 2023 are both connected to the limit pin 203, and a second through hole adapted to the limit pin 203 is opened on the tray 10 along the width direction, and the length of the second through hole is equal to the maximum movement distance of the pushing mechanism 202;

[0069] The limit bolt 203 is passed through the second through hole, and the limit bolt 203 is slidably connected to the second through hole to guide the movement of the pushing mechanism 202; the movement of the limit bolt 203 in the second through hole can also limit the movement distance of the pushing mechanism 202, which can cooperate with the above-mentioned limit mechanism 201 to make the movement of the pushing mechanism 202 more accurate and avoid movement deviation and sliding out of the tray 10.

[0070] The disclosed embodiment also provides a high-temperature formation device, including a high-temperature formation box 70, and also includes the battery clamp as described above, the high-temperature formation box 70 includes a plurality of clamping mechanisms 80, and the plurality of clamping mechanisms 80 are arranged in the high-temperature formation box 70, and the two sides of the tray 10 are respectively connected to the clamping mechanisms 80, so that the battery clamp is fixedly placed in the high-temperature formation box 70; the battery clamp is fixedly placed in the high-temperature formation box 70 by the clamping mechanisms 80, so that the high-temperature formation box 70 can process multiple batteries 50 at the same time, and ensure the stability and reliability of the batteries 50 in a high-temperature environment, and the connection between the battery clamp and the high-temperature formation box 70 is tight and not easy to loosen or fall off, thereby reducing potential safety risks.

[0071] Furthermore, in the present embodiment, the clamping mechanism 30 is electrically connected to the high-temperature formation box 70; by electrically connecting the clamping mechanism 30 to the high-temperature formation box 70, the use of additional energized parts is reduced, and it is more convenient to operate multiple batteries 50 at the same time, so that the overall space occupied by the high-temperature formation box 70 is smaller and easier to install, maintain and expand.

[0072] The following will fully describe the working process of a battery clamp and a high-temperature formation device of this embodiment in combination with the above contents.

[0073] First, adjust the spacing between the two clamping mechanisms 30 to a suitable distance for clamping the battery 50, place the pole ear of the battery 50 in the clamping area, and start the driving assembly 20 to move the pushing mechanism 202 toward the movable part 302, thereby pushing the movable part 302 to move closer to the fixed part 301, and gradually clamp the battery pole ear; when all batteries 50 are clamped by the clamping assembly, adjust the bracket assembly 40 to a suitable position, tighten the battery cell 50, and then place the entire battery fixture into the high-temperature forming box 70, and make the front part of the tray 10 with the tray positioning block 101 close to the entrance side of the high-temperature forming box 70; clamp and tighten both sides of the tray through the clamping mechanism 80 for subsequent processing.

[0074] After the processing is completed, the clamping mechanism 80 is released, the battery clamp is taken out from the high-temperature forming box 70, and the bracket assembly 40 is adjusted to release the battery cell 50. The driving assembly 20 is no longer driven, so that the movable part 302 moves away from the fixed part 301 through the elastic force of the elastic part 303 to release the battery ear and take out the battery.

[0075] The above operation adjusts the distance between the two clamping mechanisms to adapt to batteries of different sizes, and then clamps the battery ears through the cooperation of the fixed part and the movable part, and clamps the battery ears of different specifications by sliding the movable part at different distances, so that the entire clamping assembly has strong adaptability and can adapt to batteries of different overall sizes and different battery ear specifications; and the automatic operation of clamping and loosening the battery ears can be achieved through the drive of the drive assembly and the elastic force of the spring. The movable part is driven by the power mechanism to approach the fixed part, that is, to clamp the battery, and when the power mechanism stops driving, the elastic force of the spring returns the movable part to the initial position, that is, to loosen the clamped battery ears, thereby avoiding the cumbersome process and troublesome clamping caused by manual clamping.
