Description

Technical Field

[0001] The utility model relates to the field of battery cell processing, in particular to a novel battery cell grooving and necking mechanism. Background Art

[0002] With the increasingly serious energy crisis and environmental problems, and with the strong support of the country for the new energy industry, the key technologies of power battery cells have gradually matured, and various power battery cells have been widely used in electric cars, electric motorcycles, electric bicycles, solar energy, mobile communication terminal products, energy storage and other products.

[0003] Grooving and necking are essential processes in battery cell manufacturing. In traditional battery cell processes, necking is performed first and then grooving. Creases are generated after necking, resulting in uneven slot openings after grooving, causing poor sealing of the battery cell; and metal dust is generated during the grooving process, which is not easy to remove and is likely to cause internal short circuits in the battery cell, affecting the performance and safety of the battery cell and not meeting the normal use requirements. For this reason, a novel battery cell grooving and necking mechanism is proposed. Summary of the Utility Model

[0004] The utility model aims to provide a technical solution to solve the above problems in order to overcome the above deficiencies.

[0005] A novel battery cell grooving and necking mechanism includes a workbench. A necking main body is vertically arranged at the top end of the workbench, and a limiting cylinder is vertically arranged inside the necking main body. A moving clamping jaw is vertically rotatably arranged inside the limiting cylinder. A limiting platform is horizontally arranged at the top end of the necking main body. A battery cell is vertically inserted upside down in the middle position of the limiting platform, and the opening of the battery cell is located between the moving clamping jaws. Thus, the battery cell is limited and fixed by the limiting platform. The moving clamping jaw is provided with grooving pieces, and the grooving pieces are all horizontally located at the top end of the moving clamping jaw, and the grooving pieces and the moving clamping jaw move in the same direction.

[0006] Preferably, a support frame is arranged between the limiting platform and the workbench, and the support frames are vertically arranged on both sides of the surface of the workbench and are connected to the limiting platform.

[0007] Preferably, a through hole is arranged between the limiting platform and the battery cell. The through hole is formed on the limiting platform, and the battery cell is inserted into the through hole.

[0008] Preferably, the limiting platform is provided with sensors. The sensors are electrically arranged on both sides of the top end of the limiting platform, and the sensors are parallel to the battery cell.

[0009] Preferably, the workbench is provided with a material receiving port. The material receiving port is vertically arranged at the bottom end of the workbench, and one end of the material receiving port is communicated with the necking main body.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the moving jaw clamps the opening of the battery cell, the grooving piece will contact the outside of the opening of the battery cell. At this time, the moving jaw continues to close towards the middle, so that the grooving piece presses on the outside of the opening of the battery cell and the moving jaw rotates, thereby causing the outside of the opening of the battery cell to be formed into a rolling groove by rolling pressure, ensuring the neatness of the groove opening and continuing to close towards the middle by the moving jaw, thereby compressing the opening of the battery cell, making it easier to remove metal dust, not only ensuring the sealing performance of the battery cell, but also preventing impurities from entering the inner cavity of the battery cell steel shell, affecting the battery quality and safety, and further ensuring to meet the normal use requirements.

[0011] Additional aspects and advantages of the present utility model will be given in part in the following description, become apparent in part from the following description, or be understood through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0018] Please refer to Figures 1-3, in the embodiment of the present utility model, a new type of core rolling groove and necking mechanism includes a workbench 1. A necking main body 2 is vertically arranged at the top end of the workbench 1, and a limiting cylinder 7 is vertically arranged inside the necking main body 2. A moving jaw 8 is vertically rotatably arranged inside the limiting cylinder 7. A limiting platform 4 is horizontally arranged at the top end of the necking main body 2, and a core 5 is vertically inserted upside down at the middle position of the limiting platform 4. The opening of the core 5 is located between the moving jaws 8. Thus, the core 5 is limited and fixed by the limiting platform 4. The moving jaw 8 is provided with grooving pieces 9, and the grooving pieces 9 are all horizontally located at the top end of the moving jaw 8, and the grooving pieces 9 and the moving jaw 8 move in the same direction. Thus, when the moving jaw 8 clamps the opening of the core 5, the grooving piece 9 will contact the outside of the opening of the core 5. At this time, the moving jaw 8 continues to close towards the middle, so that the grooving piece 9 presses the outside of the opening of the core 5 and the moving jaw 8 rotates, thereby making the outside of the opening of the core 5 roll and press to form a rolling groove (not shown in the figure), ensuring the neatness of the groove opening. And by the moving jaw 8 continuing to close towards the middle, the opening of the core 5 is compressed, which is more convenient for removing metal dust, not only ensuring the sealing of the core, but also preventing impurities from entering the inner cavity of the core steel shell and affecting the battery quality and safety, thus ensuring to meet the normal use requirements.

[0019] A support frame 3 is arranged between the limiting platform 4 and the workbench 1, and the support frames 3 are vertically arranged on both sides of the surface of the workbench 1, and the support frames 3 are all connected with the limiting platform 4. Thus, the limiting platform 4 is horizontally located on the necking main body 2.

[0020] A through hole (not shown in the figure) is arranged between the limiting platform 4 and the core 5, and the through hole is formed on the limiting platform 4, and the core 5 is inserted into the through hole. Thus, the core 5 is vertically inserted on the limiting platform 4 through the through hole.

[0021] The limiting platform 4 is provided with sensors (not shown in the figure), and the sensors are electrically arranged on both sides of the top end of the limiting platform 4, and the sensors are parallel to the core 5. Thus, the core 5 is positioned by the sensors.

[0022] The workbench 1 is provided with a material receiving port 6, and the material receiving port 6 is vertically arranged at the bottom end of the workbench 1, and one end of the material receiving port 6 communicates with the necking main body 2. Thus, the waste chips generated when the core 5 is rolled and grooved are centrally collected through the material receiving port 6.

[0023] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model.
