Abstract
Description
Technical Field
[0001] This utility model specifically relates to a battery cell module stacking fixture. Background Technology
[0002] With the expansion of the electric vehicle market and the large-scale production of power lithium-ion battery packs, battery manufacturers typically use equipment to prevent mistaken stacking of modules during manufacturing to avoid mass scrapping of modules. However, when equipment malfunctions and repairs take too long, affecting production output, manual stacking is necessary for mass production. This process is prone to errors such as reversed polarity during module stacking and incorrect placement of spacers or aerogel materials between cells. Therefore, we propose a cell module stacking fixture. Utility Model Content
[0003] The purpose of this invention is to provide a battery cell module stacking fixture to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a battery cell module stacking fixture, comprising:
[0005] A positioning plate, with a battery cell module disposed below the positioning plate;
[0006] The positioning plate has its two ends folded downward to form positioning folds corresponding to the end of the battery cell module. A first observation hole is provided on one end of the inner side of the positioning plate, and a second observation hole is provided on the other end of the inner side, which is offset from the first observation hole. Both the first and second observation holes are rectangular.
[0007] It is convenient to observe the materials between the battery cells through the first observation hole and the second observation hole to determine whether the materials are placed incorrectly.
[0008] Preferably, the angle between the positioning fold and the positioning plate is 90°.
[0009] Better alignment of the positioning plate with the end of the battery cell module.
[0010] Preferably, a through hole is provided on the inner side of the positioning fold, and the through hole corresponds to the explosion-proof valve provided at one end of the battery cell module.
[0011] It allows for easy observation of the cell polarity and explosion-proof valve through the through-hole.
[0012] Preferably, the positioning plate is made of metal or plastic.
[0013] Preferably, a handle is fixed on the positioning plate, and the handle is "L" shaped.
[0014] This makes it easier to remove the positioning plate.
[0015] Preferably, multiple first observation holes are arranged side by side along the short side of the positioning fold.
[0016] This facilitates better observation.
[0017] Preferably, the length of the positioning plate is the same as the length of the battery cell module.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] This application, by setting a positioning plate, a first observation hole, a second observation hole, and a positioning folded edge, avoids the reverse polarity when the modules are stacked, as well as the misplacement of spacers or aerogel materials between cells. After this tooling is used with the module, the materials can be observed and compared through the holes. If the materials are consistent, it means that the product is qualified. This can effectively reduce the flow of unqualified products to the next station, and facilitate timely detection and rework at this station. 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 1-6 This utility model provides a technical solution: a battery cell module stacking fixture, comprising:
[0029] Positioning plate 3, with battery cell module 1 located below positioning plate 3;
[0030] The positioning plate 3 has two ends folded down to form a positioning folded edge 7 corresponding to the end of the battery cell module 1. A first observation hole 5 is provided on one end of the inner side of the positioning plate 3, and a second observation hole 6 is provided on the other end of the inner side, which is offset from the first observation hole 5. Both the first observation hole 5 and the second observation hole 6 are rectangular.
[0031] The positioning fold 7 facilitates quick alignment with both ends of the battery cell module 1. Then, the materials between the battery cells are observed through the first observation hole 5 and the second observation hole 6 to determine whether the materials are placed incorrectly, so that non-conforming materials can be reworked in a timely manner.
[0032] In this embodiment, preferably, the angle between the positioning folded edge 7 and the positioning plate 3 is 90°;
[0033] This facilitates better alignment with the end of the battery cell module 1.
[0034] In this embodiment, preferably, a through hole 8 is provided through the inner side of the positioning folded edge 7, and the through hole 8 corresponds to the explosion-proof valve 2 provided at one end of the battery cell module 1;
[0035] It makes it easy to observe the polarity of the battery cell and determine whether the battery cell is installed backwards.
[0036] In this embodiment, preferably, the positioning plate 3 is made of metal or plastic.
[0037] In this embodiment, preferably, a handle 9 is fixed on the positioning plate 3, and the handle 9 is "L" shaped;
[0038] This makes it easier to place the positioning plate 3 onto the cell module 1, or remove it from the cell module 1.
[0039] In this embodiment, preferably, multiple first observation holes 5 are arranged side by side along the short side of the positioning folded edge 7;
[0040] This allows for better observation of the effects.
[0041] In this embodiment, preferably, the length of the positioning plate 3 is the same as the length of the battery cell module 1.
[0042] The working principle and usage process of this utility model are as follows: During use, according to process requirements, the battery cells are stacked side-by-side in a series configuration (positive, negative, etc.). The material ratio between the battery cells is spacer:aerogel = 1:1. Then, the positioning plate 3 is engaged with the battery cell module 1 via the positioning folded edges 7 at both ends. The positioning folded edges 7 are flush with the edge of the end of the battery cell module 1. Finally, the consistency of the material is observed according to different holes on the same side to prevent incorrect material placement between battery cells and reversed polarity stacking leading to parallel connection. Figure 5A plan view of the tooling unfolded, such as Figure 6 As shown in the plan view where the tooling is placed on the module, one side shows white aerogel and blue explosion-proof valve 2, while the other side shows black spacers and blue explosion-proof valve 2. The consistency of materials on one side can effectively prevent errors in the module. In addition, this tooling can also observe all materials and cell polarity, avoiding the problem of missing materials and cell polarity.
