Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, in particular to a battery nickel sheet bending mechanism. Background Art

[0002] In the battery manufacturing process, nickel sheets are widely used as positive electrode materials for batteries due to their excellent conductivity and corrosion resistance. In order to improve the energy density and safety of the battery, it is usually necessary to bend the battery nickel sheets. However, there are some problems with the existing bending mechanisms, such as low bending accuracy and unsatisfactory bending effects. Generally speaking, this has high standard requirements for the bending angle of the nickel sheet, and different bending effects need to be processed through different battery shapes.

[0003] Most traditional bending machines directly place nickel sheets on the bending machine for bending, and then trim them. The sizes of the nickel sheets formed in this way are different, which affects the processing effect of the later products. In addition, some nickel sheet structures with special requirements still rely on operators to bend them manually, but the consistency of the nickel sheets bent manually is poor, resulting in the inability of the nickel sheets of the battery pack assembled in the subsequent process to fit well on the nickel bricks, which can easily lead to the phenomenon of cold welding between the nickel sheets and nickel bricks during laser welding, affecting product quality. Utility Model Content

[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope protected by the present utility model.

[0024] As shown in Figures 1 - 3 , the present utility model provides a battery nickel sheet bending mechanism, including:

[0025] A jig box 7 for providing a device installation foundation. A non-slip pad made of rubber is provided below the jig box 7 and is respectively arranged at the four corner positions of the jig box 7, which can support the jig box 7 and ensure the stability of the nickel sheet 10 during operation;

[0026] A fixing plate 8 is arranged on the jig box 7. There is a fixing plate 8 on the jig box 7. The fixing plate 8 is a flat plate horizontally arranged on the jig box 7 and is used to provide an installation position for the vertical frame 66. The fixing plate 8 and the jig box 7 are provided with mounting holes corresponding in position, which can be directly positioned during installation and reduce the installation difficulty;

[0027] A vertical frame 66 is arranged above the fixing plate 8. A bending cylinder 5 is arranged on the outer wall of the vertical frame 66. The vertical frame 66 is a vertically arranged bracket and is installed above the fixing plate 8 and is used to provide an installation position for the bending cylinder 5. A movable bracket 4 is arranged below the bending cylinder 5. The movable bracket 4 is provided with a plurality of vertically arranged mounting holes. The movable bracket 4 is horizontally installed below the bending cylinder 5. The movable bracket 4 is of an L-shaped structure, and the vertically arranged side thereof is used to install the bending knife 3. The position of the mounting holes can be adjusted according to the tool model, so as to meet different production requirements;

[0028] A bending knife 3 is arranged on the outer wall of the bending cylinder 5. The bending knife 3 is vertically arranged and can follow the downward movement of the bending cylinder 5 to bend the nickel sheet 10 of the battery 1;

[0029] During use, the operator aligns the battery 1 to be bent with the fixing plate 8, and then pushes the battery 1 close to the bending plate 9. The nickel sheet 10 is placed above the bending plate 9. After positioning, the bending cylinder 5 drives the movable bracket 4 and the bending knife 3 to move downward, so that the tool contacts the nickel sheet 10 at the end of the battery 1 to achieve bending. Then the bending cylinder 5 resets and drives the movable bracket 4 and the bending knife 3 to move upward, so as to take out the battery 1 for replacement, so as to repeat the next step of processing.

[0030] Preferably, a clamping groove for installing the bending plate 9 is formed on the surface of the fixing plate 8. The size of the clamping groove corresponds to the position of the bending plate 9, enabling the bending plate 9 to be directly snapped into the clamping groove during installation, thereby reducing the installation difficulty.

[0031] Preferably, there are two bending cylinders 5, which are arranged in a symmetric structure. The position and number of the bending knives 3 correspond to those of the bending cylinders 5. The number of the bending cylinders 5, the bending knives 3, and the movable brackets 4 can all be adjusted according to the model and structural design of the battery 1, so as to meet different bending requirements.

[0032] In another embodiment, a positioning block 2 is provided on the bending plate 9. The positioning block 2 is arranged in the middle of the bending plate 9 and extends out of the edge of the bending plate 9. During the bending process, the end face of the battery 1 can be abutted against the positioning block 2, so as to confirm the distance between the nickel sheet 10 and the bending knife 3, thereby ensuring the subsequent bending accuracy. At the same time, the width of the positioning block 2 is the same as the distance between the two nickel sheets 10 on the battery 1, so as to achieve bending cooperation.

[0033] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
