Description

Technical Field

[0001] This utility model specifically relates to a protective plate limiting device for a PACK module. Background Technology

[0002] Battery pack assembly is a crucial step in the battery pack manufacturing process. In the context of new energy lithium-ion battery packs, "packaging" generally refers to the process of packaging, encapsulation, and assembly. For example, connecting two batteries in series to form a specific shape according to customer requirements constitutes a "pack." Packaging is a key step in the production, design, and application of new energy lithium-ion power battery systems. For packs, the battery module is particularly important. A module consists of a certain number of cells stacked in series and parallel, with side panels installed at both ends. These side panels protect the cells within the module and effectively prevent damage to the module from the enclosure during installation. Therefore, the side panels are a vital component of the module.

[0003] Existing side guards are mostly installed manually, which is highly unpredictable. Misalignment often occurs during module side guard installation, affecting product quality. Furthermore, since the module requires constant pressure, rework is difficult and it is not easy to ensure product quality. Therefore, we propose a guard plate limiting device for PACK modules. Utility Model Content

[0004] The purpose of this utility model is to provide a protective plate limiting device for PACK modules, so as to solve the problem mentioned in the background art that the existing side protective plates are subject to arbitrary manual installation, which makes it difficult to avoid the side protective plates from being misaligned and affecting product quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective plate limiting device for a PACK module, comprising:

[0006] Limiting motherboard;

[0007] The limiting subplate is installed at both ends of the limiting main plate via a length adjustment assembly;

[0008] A positioning groove is formed at the lower end of one side wall of the limiting sub-plate to correspond to the cell electrode post;

[0009] An insulating pad layer is provided on the front surface of the limit board for insulation during protection.

[0010] The positioning groove facilitates the engagement of the battery cell terminals with the PACK module, allowing the limiting main board and limiting sub-board to be positioned correctly. This enables the limiting main board and limiting sub-board to limit the side guard plate of the PACK module, ensuring accurate installation of the side guard plate and preventing misalignment that could affect product quality. Furthermore, the addition of an insulating pad reduces scratches on the battery cell module material and prevents short circuits and sparks caused by tooling issues.

[0011] Preferably, the length adjustment assembly includes a slider, an adjustment groove, and a locking bolt. The limiting main plate has sliders at both ends, the adjustment groove is slidably disposed inside the slider, and one end of the adjustment groove is fixed to the limiting sub-plate. The limiting main plate is connected to a locking bolt that abuts against the adjustment groove through a threaded portion.

[0012] This allows for adjustments based on the actual length of the PACK module, thereby increasing the applicability and practicality of the device.

[0013] Preferably, the cross-section of the adjusting groove is "T" shaped.

[0014] This allows the slider to extend from the inside of the adjustment groove, thereby adjusting the length of the limit main board.

[0015] Preferably, one end of the limiting plate is provided with a rounded corner.

[0016] By rounding the corners, damage to operators and the battery cells in the module can be avoided.

[0017] Preferably, the insulating pad layer is made of one or more of the following materials: silica gel, Teflon, PP, PVC, CPVC, and PMMA.

[0018] This allows for better flexibility and insulation, thereby reducing scratches on the battery cell and minimizing arcing caused by short circuits.

[0019] Preferably, two limiting sub-plates are provided, and the two limiting sub-plates are symmetrically distributed along the center of one long side of the limiting main plate.

[0020] This facilitates better alignment and positioning of the battery cells at both ends of the PACK module.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This patented device, by incorporating a limiting main board, an insulating pad layer, a limiting sub-plate, a positioning groove, and a length adjustment component, allows for easy adjustment based on the actual length of the PACK module. This enables the positioning groove to mate with the cell terminals for positioning and installation. The cell terminals serve as a limiting reference for the tooling, ensuring that the tooling, after installation, does not extend beyond the large surface area of ​​the cells on both sides of the module, thus avoiding the misalignment that often occurs during manual installation of the module's side panels. This improves the accuracy of side panel installation, guarantees product quality, and the device's simple structure and ease of use enhance its practical effectiveness. Attached Figure Description

[0027] 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.

[0028] Please see Figures 1-3 This utility model provides a technical solution: a protective plate limiting device for a PACK module, comprising:

[0029] Limit motherboard 1;

[0030] The limiting subplate 3 is installed at both ends of the limiting main plate 1 via a length adjustment assembly;

[0031] The positioning groove 4 is opened at the lower end of one side wall of the limiting sub-plate 3 to correspond to the battery cell electrode post;

[0032] An insulating pad layer 2 is disposed on the front surface of the limiting main board 1 to provide insulation during protection.

[0033] The positioning groove 4 facilitates the engagement of the battery cell terminals of the PACK module, thereby positioning the main limiting plate 1 and the secondary limiting plate 3 in place. This allows the side guard plate of the PACK module to be positioned accurately by the main limiting plate 1 and the secondary limiting plate 3, ensuring that the side guard plate is installed correctly to avoid misalignment and affecting product quality. At the same time, the insulating soft pad layer 2 reduces scratches on the battery cell module material due to its softness, and the insulating material can prevent the battery cell from short-circuiting or sparking due to tooling.

[0034] In this embodiment, preferably, the length adjustment assembly includes a slider 501, an adjustment groove 502, and a locking bolt 503. The limiting main plate 1 has sliders 501 at both ends, the adjustment groove 502 is slidably disposed inside the slider 501, and one end of the adjustment groove 502 is fixed to the limiting sub-plate 3. The limiting main plate 1 is connected to the locking bolt 503, which abuts against the adjustment groove 502, through a threaded part.

[0035] This allows for adjustments based on the actual length of the PACK module, thereby increasing the applicability and practicality of the device.

[0036] In this embodiment, preferably, the cross-section of the adjusting groove 502 is "T" shaped.

[0037] This allows the slider 501 to extend from the inside of the adjusting groove 502, thereby adjusting the length of the limiting main board 1.

[0038] In this embodiment, preferably, one end of the limiting plate 3 is provided with a rounded corner 301.

[0039] By rounding the corners, damage to operators and the battery cells in the module can be avoided.

[0040] In this embodiment, preferably, the insulating pad layer 2 is made of one or more of the following materials: silica gel, Teflon, PP, PVC, CPVC and PMMA.

[0041] This allows for better flexibility and insulation, thereby reducing scratches on the battery cell and minimizing arcing caused by short circuits.

[0042] In this embodiment, preferably, two limiting sub-plates 3 are provided, and the two limiting sub-plates 3 are symmetrically distributed along the center of one long side of the limiting main plate 1.

[0043] This facilitates better alignment and positioning of the battery cells at both ends of the PACK module.

[0044] The working principle and usage process of this utility model are as follows: After the PACK modules are stacked, the cell terminals at both ends of the module are used for positioning. The module side guard plate is installed with the large surface of the cell as the reference. When installing the module side guard plate during battery module production, the locking bolt 503 is loosened first according to the length of the module. The adjusting slide 502 is pulled out from the inside of the slider 501 so that the limiting sub-plate 3 corresponds to both ends of the module. The positioning groove 4 on the side of the limiting sub-plate 3 is aligned with the cell terminal, so that the cell terminal serves as the basis for tooling positioning. This ensures that the tooling does not exceed the large surface of the cell on both sides of the module after installation, thus affecting the installation of the module side guard plate. The side guard plate is then positioned by the limiting sub-plate 3 and the limiting main plate 1 to ensure that the side guard plate is accurately installed and to avoid skewing that could affect product quality.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
