A high-adaptation tray for a square battery pack

Abstract

This utility model provides a highly adaptable tray for square battery packs, including a tray base plate and a limiting structure disposed on the top of the tray base plate. The limiting structure is used to clamp and fix the outer shell of the battery pack. The limiting structure includes two limiting bases arranged side by side and a limiting unit disposed between the two limiting bases. The limiting unit includes four limiting blocks evenly disposed on the two limiting bases and threaded fasteners disposed between the limiting blocks and the limiting bases. The threaded fasteners are used to press and fix the limiting blocks and the limiting bases tightly. By simply loosening the threaded fasteners on the limiting blocks, the relative position of the limiting blocks and the limiting bases can be changed to adapt to battery pack shells of different widths. This can greatly reduce the warehousing and financial pressure on lithium battery pack manufacturers.

Description

Technical Field

[0001] This utility model relates to battery pack processing accessories, and in particular, to a highly adaptable tray for a square battery pack. Background Technology

[0002] The production process of lithium battery packs is divided into three stages: front-end, middle-end, and back-end. The purpose of the front-end process is to process the raw materials into electrode sheets, and the core process is coating. The purpose of the middle-end process is to process the electrode sheets into unactivated cells. The purpose of the back-end process is to test and package, and the core processes are formation and capacity testing.

[0003] The subsequent processes mainly include packaging, formation and capacity testing, testing and sorting, module assembly, and PACK assembly. Packaging involves placing the battery cells into a metal or pouch casing. Formation is the process of activating the positive and negative electrode materials inside the battery through charging and discharging, thus activating the battery. Capacity testing, after formation, involves cycling the battery through charging and discharging and testing various battery parameters, and then grouping the batteries according to the measured parameters. Module assembly and PACK assembly include testing the upper limit of the battery module, assembling the battery pack, and testing the battery pack before it leaves the production line. After this process, the battery basically meets the factory requirements.

[0004] When encapsulating lithium battery packs, metal or soft-pack shells need to be clamped and fixed using a tray. However, existing trays mostly use a fixed structure, which can only be adapted to a single type of shell, resulting in poor compatibility. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a highly adaptable tray for square battery packs, which can be adapted to various models of battery pack shells and has the advantage of high adaptability.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a highly adaptable tray for a square battery pack, including a tray base plate and a limiting structure disposed on the top of the tray base plate. The limiting structure is used to clamp and fix the outer shell of the battery pack. The limiting structure includes two limiting bases arranged side by side and a limiting unit disposed between the two limiting bases. The limiting unit includes four limiting blocks evenly disposed on the two limiting bases and threaded fasteners disposed between the limiting blocks and the limiting bases. The threaded fasteners are used to press and fix the limiting blocks and the limiting bases.

[0007] With the above technical solution, when in use, it is only necessary to loosen the threaded fasteners on the limiting block to change the relative position of the limiting block and the limiting base to adapt to battery pack shells of different widths. After that, it is only necessary to tighten the limiting block to fix it and limit the lithium battery pack.

[0008] The tray designed as described above can accommodate lithium battery packs of different widths, offering high adaptability. Furthermore, using this tray design can significantly reduce the warehousing and financial burdens on lithium battery pack manufacturers.

[0009] Preferably, the limiting base has a guide groove along its length, and the threaded fastener includes a fastening bolt that passes through the limiting block and a fastening nut that is slidably disposed in the guide groove. The threaded end of the fastening bolt passes through the guide groove and is threadedly connected to the fastening nut.

[0010] Through the above technical solution, the guide groove, in conjunction with the threaded fasteners set above, can be used to limit and guide the movement of the limit block.

[0011] Preferably, each of the two limiting bases has a storage opening at its opposite position, the guide groove is formed at the bottom of the storage opening, and the limiting block is slidably disposed in the corresponding storage opening.

[0012] Through the above technical solution, the side wall of the storage opening can abut against the limiting block to limit its movement. Furthermore, placing the limiting block in the storage opening can reduce the height of the tray, further alleviating the storage pressure on lithium battery pack manufacturers.

[0013] Preferably, the bottom edge of the limiting opening is provided with a scale.

[0014] With the above technical solution, users can make more precise adjustments to the limit block using the scale.

[0015] Preferably, positioning openings are provided at opposite positions of the two limiting blocks on the same limiting base, and the shape of the positioning openings is adapted to the shape of the battery pack shell.

[0016] The above technical solution allows the shape of the positioning opening to match the shape of the battery pack casing, thus enabling more stable positioning of the battery pack casing.

[0017] Preferably, the tray base plate has a waist-shaped mounting hole, which is staggered with the limiting base. A locking bolt is provided at the bottom of the tray base plate, and the threaded section of the locking bolt passes through the waist-shaped mounting hole and is threaded to the limiting base.

[0018] The above technical solution uses waist-shaped mounting holes and locking bolts to detachably connect the limiting base to the tray bottom plate. This allows the distance between the two limiting bases to be adjusted according to the length of the battery pack casing, further improving the adaptability of the tray.

[0019] Preferably, the waist-shaped mounting hole is perpendicular to the limiting base.

[0020] With the above technical solution, the waist-shaped mounting hole is perpendicular to the limiting base, making the adjustment of the limiting base more rapid.

[0021] Preferably, the tray bottom plate is provided with lifting handles on both opposite sides of the top.

[0022] The above technical solution allows for convenient handling of pallets by pulling the handle. Attached Figure Description
