Description

Technical Field

[0001] This utility model belongs to the field of lithium battery technology, specifically relating to a liquid injection and unloading clamp for soft-pack lithium batteries. Background Technology

[0002] With the rapid development of the new energy industry, pouch lithium-ion batteries have been widely used in electric vehicles, consumer electronics, and energy storage due to their high energy density, lightweight, and flexibility. However, in the automated electrolyte filling process of lithium battery production, the traditional fixture design has significant drawbacks: the fixture is semi-enclosed, obscuring the battery body and making it difficult to monitor the electrolyte filling process in real time; at the same time, electrolyte easily seeps into the fixture groove, and if it cannot be drained in time, it will lead to cross-contamination of the electrolyte, seriously affecting battery performance and production efficiency. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a soft-pack lithium battery electrolyte injection and receiving fixture, which can realize the visualization of the electrolyte injection process and the effective management of electrolyte contamination of the product, significantly improving production efficiency and product quality.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A soft-pack lithium battery liquid filling and receiving clamp includes a tray clamp and a positioning clamp. The tray clamp is elongated and has a V-shaped groove extending along its length. The bottom of the V-shaped groove has a drain hole, and the tray clamp has a back beam on the back side of the V-shaped groove. The positioning clamp is elongated and is mounted on top of the back beam and parallel to the back beam. The positioning clamp is adjustable along the length of the tray clamp and has multiple locking parts arranged at intervals along its length. The locking parts are located above the V-shaped groove, and the locking parts have locking grooves that can lock the battery air bag.

[0006] As a preferred embodiment of this utility model, the positioning clamp has a plurality of elongated holes spaced apart along the length direction of the positioning clamp on the side away from the snap-fit ​​part, and the extension direction of the elongated holes is consistent with the length direction of the positioning clamp; the back beam has a plurality of threaded holes corresponding to the elongated holes, and screws pass through the elongated holes and connect to the threaded holes.

[0007] As a preferred embodiment of this utility model, a plurality of drainage holes are provided, and the plurality of drainage holes are arranged at intervals along the length direction of the V-shaped groove.

[0008] As a preferred embodiment of this utility model, the slot of the snap-fit ​​groove is provided with a V-shaped inlet.

[0009] As a preferred embodiment of this utility model, the soft-pack lithium battery liquid injection and unloading clamp also includes a frame, which is composed of two support columns, which are arranged at intervals, and the two ends of the back beam are respectively fixedly connected to the support columns.

[0010] As a preferred embodiment of this utility model, the V-shaped groove is a through groove with openings at both ends, and the openings at both ends of the V-shaped groove are spaced apart from the column.

[0011] Compared with the prior art, the soft-pack lithium battery liquid filling and unloading clamp of this utility model has the following advantages:

[0012] (1) The tray clamp adopts a V-groove design, which can adapt to soft-pack lithium batteries of different sizes and ensure that the batteries can be placed stably. At the same time, a drain hole is designed at the bottom of the V-groove. The drain hole serves as an electrolyte discharge channel. If the electrolyte accidentally flows into the V-groove, it can be quickly discharged through the drain hole, effectively preventing electrolyte accumulation and cross-contamination.

[0013] (2) The positioning fixture is installed on the back beam and can be adjusted along the length of the tray fixture. With flexible adjustment, it can accurately engage with the battery air bag part through the snap-fit ​​groove on the snap-fit ​​part, so that the battery air bag part is kept upright and accurately positioned, ensuring that each battery is in a stable and upright optimal state during the liquid injection process. At the same time, since the snap-fit ​​part only holds the battery air bag part, the positioning fixture will not obstruct the battery body, realizing the visualization of the liquid injection process, improving the transparency and controllability of the production process, and ensuring the stability of the liquid injection quality.

[0019] 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. 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.

[0020] like Figure 1 and Figure 2 As shown in the figure, the present invention provides a soft-pack lithium battery liquid filling and receiving clamp, which includes a tray clamp 1 and a positioning clamp 2. The tray clamp 1 is elongated and has a V-shaped groove 11 extending along its length. The bottom of the V-shaped groove 11 has a drain hole (not shown in the figure). The tray clamp 1 has a back beam 12 on the back side of the V-shaped groove 11. The positioning clamp 2 is elongated and is installed on the top of the back beam 12 and parallel to the back beam 12. The positioning clamp 2 can be adjusted along the length of the tray clamp 1. The positioning clamp 2 has a plurality of locking parts 21 arranged at intervals along its length. The locking parts 21 are located above the V-shaped groove 11. The locking parts 21 have locking grooves 22 that can lock the battery air bag.

[0021] Therefore, the core technology of the soft-pack lithium battery electrolyte filling and unloading clamp according to the embodiment of this utility model lies in: the tray clamp 1 adopts a V-groove 11 design, which can adapt to soft-pack lithium batteries of different sizes and ensure that the batteries can be placed stably; and, by designing a drain hole at the bottom of the V-groove 11, the drain hole serves as an electrolyte discharge channel. Once the electrolyte accidentally flows into the V-groove 11, it can be quickly discharged through the drain hole, effectively preventing electrolyte accumulation and cross-contamination; secondly, the positioning clamp 2 is installed on the back beam 12 and can move along the tray clamp The length direction of the clamp 1 can be adjusted so that, with flexible adjustment, it can accurately engage with the battery air bag part through the clamping groove 22 on the clamping part 21, so that the battery air bag part is kept in an upright position, achieving precise positioning and ensuring that each battery is in a stable and upright optimal state during the liquid injection process. Furthermore, since the clamping part 21 only clamps the battery air bag part, the positioning clamp 2 will not obstruct the battery body, realizing the visualization of the liquid injection process, improving the transparency and controllability of the production process, and ensuring the stability of the liquid injection quality.

[0022] For example, to facilitate the adjustment of the positioning clamp 2, the positioning clamp 2 has multiple elongated holes 23 spaced apart along its length on the side away from the locking part 21. The extension direction of the elongated holes 23 is consistent with the length direction of the positioning clamp 2. The back beam 12 has multiple threaded holes (not shown in the figure) corresponding to the elongated holes 23. Screws 4 pass through the elongated holes 23 and connect to the threaded holes. When the positioning clamp 2 needs to be adjusted, the screws 4 are loosened. The screws 4 can form a guiding structure with the elongated holes 23 without disengaging from the threaded holes. At this time, the positioning clamp 2 is pushed, and the positioning clamp 2 can be adjusted along the length direction of the back beam 12, thereby causing the locking part 21 to lock or disengage from the battery air bag part. When the locking part 21 accurately locks the battery air bag part, tightening the screws 4 can achieve battery positioning. This design not only gives the positioning clamp 2 a position adjustment function, but also improves the applicability and flexibility of the positioning clamp 2, and can adapt to soft-pack lithium batteries of different specifications and sizes.

[0023] For example, multiple drain holes are provided, and the multiple drain holes are arranged at intervals along the length direction of the V-shaped groove 11 to ensure that the electrolyte can be discharged quickly, further reducing the risk of cross-contamination and improving product quality and the cleanliness of the production environment.

[0024] For example, the slot 22 is provided with a V-shaped inlet 24 to facilitate the insertion of the battery air bag into the slot 22.

[0025] For example, the soft-pack lithium battery liquid filling and receiving fixture also includes a frame, which is composed of two support columns 3, which are spaced apart, and the two ends of the back beam 12 are fixedly connected to the support columns 3 respectively.

[0026] For example, the V-shaped groove 11 is a through groove with openings at both ends, and the openings at both ends of the V-shaped groove 11 are spaced apart from the column 3. When the drain hole is blocked, the electrolyte can be discharged from the openings at both ends of the V-shaped groove 11, preventing the possibility of electrolyte accumulation in the V-shaped groove 11.

[0027] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
