DETAILED DESCRIPTION

[0026] The specific embodiments of the present application are described in further detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0027] A preferred embodiment of a module battery cell separation device of the present application is shown in Figures 1 to 10 The module battery cell separation device comprises a workbench 1, a pushing unit 2, a positioning unit 3, a pressing unit 4 and a fixing unit 5. The workbench 1 is the supporting base of the module battery cell separation device. The pushing unit 2, the positioning unit 3, the pressing unit 4 and the fixing unit 5 are arranged on the workbench 1.

[0028] The workbench 1 is a frame structure to reduce the mass of the workbench 1 while ensuring the structural strength of the workbench 1. The workbench 1 comprises a table top 11 and bridge frames 12 fixedly arranged on the table top 11. The bottom of the table top 11 is supported and fixed by legs. The bridge frames 12 are U-shaped structures. There are two bridge frames 12, which are arranged in a front-rear direction. The front-rear direction is the moving direction of the module 9 on the workbench 1. The module 9 moves from back to front on the workbench 1. The battery cells in the module 9 are arranged in the front-rear direction.

[0029] The pushing unit 2 is fixedly arranged on the bridge frame 12 of the workbench 1. The pushing unit 2 is used to push the module 9 to move in the front-rear direction, i.e. to push the module 9 to move horizontally along the arrangement direction of the battery cells. When the pushing unit 2 pushes the module 9 to move, by controlling the moving stroke of the pushing unit 2, the forward displacement of the module 9 can be controlled, so that the battery cell at the front end of the module 9 is moved to the lower side of the pressing unit 4.

[0030] The positioning unit 3 is fixedly arranged on the table top 11 of the workbench 1. The positioning unit 3 is used to position the forward direction of the module 9, i.e. to limit the module 9 to always move in the front-rear direction, to avoid the module 9 from deviating, so that the battery cells in the module 9 are perpendicular to the pressing plate 42, and to ensure that the pressing plate 42 only exerts pressure on the battery cell at the front end of the module 9.

[0031] The pressing unit 4 comprises a pressing driving member 41 and a pressing plate 42. The pressing driving member 41 is fixedly arranged on the bridge frame 12 of the workbench 1. The pressing plate 42 is in transmission connection with the pressing driving member 41. The pressing driving member 41 is used to drive the pressing plate 42 to move in the vertical direction. The pressing plate 42 is used to exert vertical pressure on the battery cell at the front end of the module 9. When the pressing driving member 41 drives the pressing plate 42 to move downward, the pressing plate 42 exerts pressure on the battery cell at the front end of the module 9. The pressure generates a shear force between the adjacent two battery cells. When the pressure is appropriate, the shear force will be greater than the adhesive force of the adhesive, so as to separate the battery cell from the module 9.

[0032] In the embodiment, the pressing unit 4 is arranged outside the bridge 12 and the table top 11, that is, the projection of the pressing unit 4 on the plane where the table top 11 is located is not on the table top 11. When the cell at the front end of the module 9 moves to the edge of the table top 11, the pushing unit 2 pushes the module 9 to move a distance of one cell width each time. After the pressing plate 42 separates the cell at the front end from the module 9, the pushing unit 2 repeatedly pushes the module 9 to move a distance of one cell width, so that the cells are separated from the module 9 one by one. The moving distance of the pushing unit 2 can be controlled by the control system to realize automatic control of the assembly line operation.

[0033] In the embodiment, the pressing plate 42 is detachably connected with the pressing driving member 41. According to different specifications and sizes of the cells, the travel of the pressing driving member 41 and the corresponding size of the pressing plate 42 are adjusted, so that different sizes of the cells can be separated, and the universality is high.

[0034] The workbench 1 is further provided with a fixing unit 5. The fixing unit 5 is used to fix the module 9 when the pressing unit 4 applies pressure to separate the cells. That is, the cells of the module 9 which are not subjected to the vertical force of the pressing plate 42 are fixed, so that the other cells of the module 9 do not swing around the cell at the front end and affect the separation of the cells, the cells are successfully separated, and the separation efficiency of the cells is improved.

[0035] When the cells of the module 9 are separated, the pushing unit 2 pushes the module 9 to move on the workbench 1, and the positioning unit 3 positions the module 9 to ensure that the cells move horizontally along the arrangement direction of the cells. By controlling the pushing distance of the pushing unit 2, the cell at the front end of the module 9 can move to the lower side of the pressing unit 4. The pressing driving member 41 drives the pressing plate 42 to move downward, the pressing plate 42 applies a vertical pressure to the cell at the front end of the module 9, the vertical pressure overcomes the force of the structural adhesive between the cells to separate the cells. The traditional freezing process and manual disassembly process are omitted, the automatic assembly line operation is realized, the cells are safely and efficiently disassembled on the assembly line, the overall disassembly production efficiency is greatly improved, and the labor cost is reduced.

[0036] Preferably, the bottom of the pressing plate 42 is provided with a pole groove 43 for avoiding the pole of the cell. The pole groove 43 is arranged at intervals on the pressing plate 42.

[0037] The bottom end face of the pressing plate 42 is the end face which contacts the cell and applies pressure to the cell. The recess is arranged at the bottom of the pressing plate 42. In the process of pressing the cell by the pressing plate 42, the pole part of the cell can be avoided, so that the whole aluminum shell on the upper surface of the cell is uniformly stressed, and the cell is not deformed due to local stress during the separation process.

[0038] Since the pressing plate 42 is detachably connected with the pressing driving member 41, when the size specification of the battery cell changes and the distance between the pole columns changes, only the corresponding pressing plate 42 needs to be replaced.

[0039] Preferably, the pressing driving member 41 is a hydraulic cylinder fixedly arranged on the workbench 1, and the pressing plate 42 is fixed to the bottom end of the hydraulic cylinder.

[0042] The fixing unit 5 is formed by the fixing cylinder 51 and the fixing pressing plate 52, and the fixing cylinder 51 can drive the fixing pressing plate 52 to move vertically. When the pressing plate 42 applies a vertical force to the battery cell at the front end of the module 9, the fixing cylinder 51 drives the fixing pressing plate 52 to move downward to press the other battery cells of the module 9, so as to ensure that the module 9 is attached to the tabletop 11 and avoid that the rear end of the module 9 is lifted to affect the separation of the battery cells; when the pushing unit 2 pushes the module 9 to move after the battery cells are separated, the fixing cylinder 51 drives the fixing pressing plate 52 to move upward to release the module 9, so as to ensure that the module 9 moves forward and backward.

[0043] In the embodiment, the fixing pressing plate 52 has a rectangular structure, and the size of the fixing pressing plate 52 is greater than the size of a single battery cell, so as to ensure that the fixing pressing plate 52 is in contact with the plurality of battery cells and the module 9 is stable.

[0045] The pushing assembly is slidingly arranged on the sliding table 21, and the servo motor 22 drives the pushing assembly to move forward and backward to make the pushing assembly push the module 9 to move. The sliding table 21 guides the moving direction of the pushing assembly, so as to ensure that the pushing assembly moves forward and backward. The servo motor 22 is used as the driving part of the pushing unit 2, and the stroke of the servo motor 22 can be controlled by controlling the stroke parameter of the servo motor 22, which is convenient to control and is suitable for the separation of battery cells of different models of the module 9. Meanwhile, the servo motor 22 is used as a closed-loop driving member, so as to accurately control the stroke of the servo motor 22, make the module 9 move a distance of the width of a battery cell each time, and facilitate the separation of the battery cells.

[0046] The length of the sliding table 21 defines the total stroke of the pushing assembly driven by the servo motor 22, and therefore the total length of the module 9 is less than the length of the sliding table 21 to ensure that the pushing assembly can drive the module 9 to move to the front end of the table 11. In the embodiment, the total stroke of the pushing assembly is 600 mm, and the total length of the module 9 is not more than 550 mm.

[0047] Preferably, the pushing assembly comprises a pushing cylinder 23 and a pushing plate 24 arranged at the bottom of the pushing cylinder 23, the pushing cylinder 23 is slidingly assembled on the sliding table 21 and is drivingly connected with the servo motor 22, and the pushing cylinder 23 is used to push the pushing plate 24 to move vertically.

[0048] The pushing assembly is formed by the pushing cylinder 23 and the pushing plate 24, the pushing cylinder 23 can push the pushing plate 24 to move vertically, when the module 9 carrying the battery cells to be separated is conveyed, the pushing cylinder 23 drives the pushing plate 24 to move upward to the highest position to avoid the module 9, so as to ensure that the module 9 moves to the appropriate position of the table 11; when it is needed to push the module 9 to move forward, the pushing cylinder 23 pushes the pushing plate 24 to move downward, and the pushing plate 24 is used to push the module 9 to move forward.
