Description

Technical Field

[0001] The utility model relates to the technical field of cell disassembly, and particularly refers to a cell disassembly tool. Background Art

[0002] In the process of battery manufacturing and maintenance, cells are the smallest functional units. These cells usually need to be stacked into modules to provide the required energy density and voltage level. In order to achieve electrical connection between cells, electrical connectors are often used to connect multiple cells in series or parallel. The existing connection methods between cells and electrical connectors are mainly divided into two types: welding and plugging.

[0003] Among them, the welding method can provide a stable electrical connection, but it has strict requirements on the quality of electrical connectors. Moreover, when disassembling cells, cutting is often required, which not only damages the cells and makes them unable to be reused, but also increases the investment cost of cutting equipment. When using plugging, the pole columns of the cells need to be accurately aligned with the corresponding slots of the electrical connectors and fixed by interference fit. Although this method avoids the problems that may be brought by welding, a series of components such as corner guards, mounting plates and end plates often need to be removed before disassembly. This series of operation processes are complex and time-consuming, also increasing the cost, and may cause unnecessary damage to the cells during the disassembly process. Summary of the Invention

[0004] The utility model is made in consideration of the foregoing problems. The purpose of the utility model is to provide a cell disassembly tool, which can realize the rapid disassembly of cells, has a simple structure and a low cost.

[0005] To achieve the above purpose, the utility model provides a cell disassembly tool. Lifting units are arranged on both symmetric sides of the cell. The cell disassembly tool includes two hooks. Each hook includes a handle and a hook body. The hook body is connected to the handle and is located below the handle.

[0006] The two hook bodies can be respectively connected to the two lifting units to drive the cell.

[0007] For the cell disassembly tool described above, a connection part that can be inserted into the lifting unit is arranged at the bottom of the hook body, and the connection part is integrally semicircular.

[0008] For the cell disassembly tool described above, the handle and the hook body are connected by welding.

[0009] For the cell disassembly tool described above, the cell includes a cell body, a housing and a pole column. The housing covers the outside of the cell body. The pole columns are arranged on both symmetric sides of the housing along the vertical direction, and the lifting units are located on the pole columns.

[0010] For a cell disassembly tool as described above, the hoisting unit is provided with a hoisting hole, and the hoisting hole is arranged on the pole column in the front-rear direction.

[0011] For a cell disassembly tool as described above, the cell further includes outer terminals and insulating members. The outer terminals are fixed on both symmetric sides of the housing through the insulating members, and the pole columns are fixed on the outer terminals and integrally formed with the outer terminals.

[0012] For a cell disassembly tool as described above, the pole column is in the shape of a frustum of a cone, and the diameter of the top of the pole column is larger than the diameter of the bottom of the pole column.

[0013] For a cell disassembly tool as described above, the pole column is in the shape of a cylinder.

[0014] The utility model has the following beneficial effects: The cell can be hoisted by the hook and driven to displace, so as to drive the cell to separate from the electrical connection member, realizing the disassembly of the cell. The operation is simple, the cell disassembly is fast, and the cost is low. Description of the Drawings

[0021] The following are specific embodiments of the utility model in combination with the drawings, and the technical solutions of the utility model will be further described, but the utility model is not limited to these embodiments.

[0022] As Figures 1-4 shown, a cell disassembly tool includes two hooks 2. The two hooks 2 are used to hoist both symmetric sides of the cell 1, realizing synchronous driving of both sides of the cell 1, so that it can be disassembled from the electrical connection member.

[0023] Specifically, lifting units are provided on two symmetric sides of the battery cell 1. Each hook 2 includes a handle 21 and a hook body 22. The hook body 22 is connected to the handle 21 and is located below the handle 21. The two hook bodies 22 can be respectively connected to the two lifting units to drive the battery cell 1, that is, the two sides of the battery cell 1 are lifted simultaneously by the two hooks 2, so that it is displaced synchronously and separated from the point connector, realizing the disassembly of the battery cell 1. Lifting the two sides of the battery cell 1 simultaneously can ensure its stability and avoid damage to the battery cell 1 due to uneven force.

[0024] Specifically, a connecting portion 221 that can be inserted into the lifting unit is provided at the bottom of the hook body 22. The connecting portion 221 is integrally semicircular, which can improve the overall load-bearing capacity of the hook body 22. The handle 21 and the hook body 22 are connected by welding to ensure the connection stability and avoid detachment.

[0025] Specifically, the battery cell 1 includes a battery cell body 11, a housing 12, and a pole 13. The housing 12 covers the outside of the battery cell body 11. The pole 13 is arranged symmetrically on two sides of the housing 12 in the vertical direction. The lifting unit is located on the pole 13. In this embodiment, the pole 13 is provided in a frustum shape or a cylindrical shape. Compared with the flat pole 13, its connection with the electrical connector does not require welding, only insertion is needed. Moreover, when different capacity battery cells 1 are required, only the size of the pole 13 needs to be changed. Similarly, the lifting unit is provided as a lifting hole 14. The lifting hole 14 is arranged on the pole 13 in the front-rear direction, and the hook body 22 of the hook 2 can be inserted into the lifting hole 14 to realize the connection with the battery cell 1.

[0026] Wherein, when the pole 13 is provided in a frustum shape, the top diameter of the pole 13 is larger than the bottom diameter of the pole 13, which is convenient for the insertion of the pole 13 and the electrical connector.

[0027] Furthermore, the battery cell 1 further includes an external terminal 15 and an insulating member. The external terminal 15 is fixed on two symmetric sides of the housing 12 through the insulating member. The pole 13 is fixed on the external terminal 15 and is integrally formed with the external terminal 15. The integral formation of the pole 13 and the external terminal 15 can ensure the connection stability. At the same time, an insulator 16 is provided between the external terminal 15 and the housing 12 to avoid leakage to the housing 12.
