Abstract
Description
Technical Field
[0001] This application relates to the field of battery technology, and in particular to a cell module assembly fixture. Background Technology
[0002] Battery cell module assembly fixtures are energy storage and supply components for electric bicycles such as electric two-wheelers and electric tricycles, directly affecting the range, performance, and lifespan of the electric bicycle. Lithium batteries are typically composed of multiple pouch cells connected in series and parallel via busbars to form a battery cell module with high voltage and high capacity.
[0003] However, in the existing technology, it is not easy to fix the soft-pack cells during the module stacking process. The cells must be placed flat on the workbench during assembly. Bending the tabs is inconvenient to operate, and they are easy to fall apart after being assembled and stood up, which affects work efficiency and is also prone to arcing due to contact between the positive and negative electrodes. Utility Model Content
[0004] This application provides a battery cell module assembly fixture, including a back plate, a bracket limiting plate, and a height limiting plate;
[0005] The back plate is vertically arranged, and a vertically arranged bracket limiting plate is connected to each of the opposite sides of the back plate;
[0006] The surfaces of the two bracket limiting plates adjacent to each other are provided with horizontal slots, which form insertion holes at the ends of the bracket limiting plates away from the back plate;
[0007] The bracket limiting plate is provided with a strip-shaped through hole that passes through the bracket limiting plate, and the height limiting plate is inserted into the strip-shaped through hole on the two bracket limiting plates.
[0008] In one possible implementation, the battery cell module assembly fixture provided in this application embodiment has limiting foam on the surfaces of the two bracket limiting plates that are adjacent to each other.
[0009] In one possible implementation, the battery cell module assembly fixture provided in this application embodiment has positioning holes on the back plate, and the bracket limiting plate has screw holes that correspond one-to-one with the positioning holes at one end of the back plate.
[0010] The back plate and the bracket limiting plate are fixed together by bolts that pass through the positioning hole and are connected to the screw hole.
[0011] Beneficial effects: The battery cell module assembly fixture can conveniently and efficiently assemble the modules, solving the problems of battery cells scattering due to the need to stand the modules upright and battery cells falling out of the tabs. This greatly improves production efficiency, reduces rework costs, and makes it easier to bend the tabs, preventing the busbars from slipping between the battery cells and causing short circuits.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0028] See Figure 1 As shown, this application provides a battery cell module assembly fixture, including a back plate 10, a bracket limiting plate 20, and a height limiting plate 30, wherein:
[0029] The back plate 10 is vertically arranged, and a vertically arranged bracket limiting plate 20 is connected to each of the opposite sides of the back plate 10. The back plate 10 is provided with positioning holes, and the end of the bracket limiting plate 20 adjacent to the back plate 10 has screw holes that correspond one-to-one with the positioning holes. The back plate 10 and the bracket limiting plate 20 are fixed by bolts that pass through the positioning holes and are connected to the screw holes.
[0030] The surfaces of the two bracket limiting plates 20 adjacent to each other are provided with horizontal slots 21, and the slots 21 form insertion holes 22 at the ends of the bracket limiting plates 20 away from the back plate 10. The surfaces of the two bracket limiting plates 20 adjacent to each other are provided with limiting foam 40, which serves to protect the battery cells.
[0031] The bracket limiting plate 20 is provided with a strip-shaped through hole 23 that passes through the bracket limiting plate 20. The height limiting plate 30 is inserted into the strip-shaped through hole 23 on the two bracket limiting plates 20. The height limiting plate 30 is used to support the battery cell.
[0032] Referring to Figures 2(a) to 2(d), during use, insert the cell support plate 51 into the slot 21 through the insertion 22 of the two support limiting plates 20, so that the cell support plate 51 is supported by the two support limiting plates 20. Then, from left to right, the soft-pack cells 52 are loaded into the fixture in the stacking order. Then, the busbar is inserted. Finally, the tabs 53 are bent and flattened. After the tabs 53 are bent, the cell support plate 51 and the soft-pack cells 52 become a whole module 50, and the whole module 50 can be easily removed from the fixture.
