[0002] During battery manufacturing and assembly, battery connectors are critical components connecting battery cells. Their quality and processing accuracy directly impact the overall performance and safety of the battery pack. Battery connectors are typically made of soft metals such as copper or aluminum, which offer excellent conductivity and mechanical toughness, but also present challenges in cutting and processing.

[0003] Traditional battery connector cutting methods often rely on mechanical stamping or shearing. These processes often generate significant impact during the cutting process, resulting in uneven cut surfaces, burrs, and flying edges. These issues not only affect the appearance quality of the battery connector but can also adversely affect its conductivity and mechanical strength, ultimately impacting the overall performance of the battery pack.

[0004] Furthermore, traditional cutting devices are prone to material rebound or deformation during cutting of soft metal battery connectors due to the inherent toughness of the material, making it difficult to ensure cutting accuracy. Furthermore, burrs and flying edges after cutting increase the difficulty and cost of subsequent processing, reducing production efficiency. Utility Model Content

[0005] The purpose of this application is to provide a battery connector cutting device that can efficiently and accurately cut battery connectors while ensuring that the cutting surface is flat, free of burrs and flying edges.

[0006] A battery connector cutting device comprises an upper cutting part and a lower cutting part, wherein the upper cutting part and the lower cutting part are arranged opposite to each other;

[0007] The upper cutting portion includes an upper mounting seat and an upper cutting knife. The upper cutting knife is located on the bottom surface of the upper mounting seat. The cross section of the upper cutting knife is a right triangle. The upper cutting knife includes a first right-angled surface and a first inclined surface. The angle between the first right-angled surface and the first inclined surface is a first acute angle. The first acute angle is used to cut the battery connector.

[0008] The lower cutting portion includes a lower mounting seat and a lower cutting knife. The lower cutting knife is located on the upper surface of the lower mounting seat. The cross section of the lower cutting knife is a right triangle. The lower cutting knife includes a second right-angled surface and a second inclined surface. The angle between the second right-angled surface and the second inclined surface is a second acute angle. The second acute angle is used to cut the battery connector.

[0009] The first acute angle and the second acute angle have the same angle. During cutting, the first inclined surface and the second inclined surface first contact the battery connector, and then the battery connector is cut through the first right-angled surface and the second right-angled surface.

[0010] In one embodiment, the first acute angle and the second acute angle are in a range of 25 to 35 degrees.

[0011] In one embodiment, the first acute angle and the second acute angle are 30 degrees.

[0012] In one embodiment, an upper guide column and an upper guide hole are provided at the bottom of the upper mounting seat.

[0013] In one embodiment, an upper screw fixing hole is provided on the side surface of the upper mounting seat, and the upper guide column is locked by a screw in the upper screw fixing hole.

[0014] In one embodiment, a lower guide column and a lower guide hole are provided on the top of the lower mounting seat.

[0015] In one embodiment, a lower screw fixing hole is provided on the side surface of the lower mounting seat, and the lower guide column is locked by a screw in the lower screw fixing hole.

[0016] Beneficial effects of this application:

[0017] (1) This application utilizes a cutting blade structure with identical first and second acute angles to ensure that the upper and lower cutting sections can precisely align during the cutting process, generating a stable cutting force. This design results in a smoother cutting surface, effectively avoiding burrs and flying edges, and significantly improving the cutting accuracy of battery connectors.

[0018] (2) During cutting, the first and second bevels first contact the battery connector, playing a role of gradual introduction, gradually increasing the cutting force, reducing the impact force at the moment of cutting, and reducing the risk of material rebound and deformation. This design not only improves the smoothness of cutting, but also helps to protect the structural integrity of the battery connector, ensuring that the connector after cutting still has good conductivity and mechanical strength.

[0028] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0029] like Figures 1 to 3 As shown, a battery connector cutting device includes an upper cutting part 1 and a lower cutting part 2, wherein the upper cutting part 1 and the lower cutting part 2 are arranged opposite to each other;

[0030] The upper cutting portion 1 includes an upper mounting seat 11 and an upper cutting knife 12. The upper cutting knife 12 is located on the bottom surface of the upper mounting seat 11. The cross section S1 of the upper cutting knife 12 is a right triangle. The upper cutting knife 12 includes a first right-angled surface 13 and a first inclined surface 14. The angle between the first right-angled surface 13 and the first inclined surface 14 is a first acute angle a. Figure 4 As shown, in this embodiment, the first acute angle a is set to 30 degrees, which is designed to efficiently and accurately cut the battery connector;

[0031] The lower cutting portion 2 includes a lower mounting seat 21 and a lower cutting knife 22. The lower cutting knife 22 is located on the upper surface of the lower mounting seat 21. The cross section S2 of the lower cutting knife 22 is a right triangle. The lower cutting knife 22 includes a second right-angled surface 23 and a second inclined surface 24. The angle between the second right-angled surface 23 and the second inclined surface 24 is a second acute angle b. Figure 4 As shown, in this embodiment, the second acute angle b is also set to 30 degrees to ensure that it matches the first acute angle a, thereby forming a stable cutting force during the cutting process.

[0032] The first acute angle a and the second acute angle b are the same. During cutting, the first inclined surface 14 and the second inclined surface 24 first contact the battery connector, and then the battery connector is cut through the first right-angled surface 13 and the second right-angled surface 23 .

[0033] During cutting, the first bevel 14 of the upper cutting section 1 and the second bevel 24 of the lower cutting section 2 first contact the battery connector, providing a gradual introduction. The battery connector is then cut through the first and second right-angled surfaces 13 and 23. This design results in a smoother cut surface, effectively avoiding burrs and flying edges, and significantly improving the cutting accuracy of battery connectors.

[0034] In one embodiment, the first acute angle and the second acute angle are in a range of 25 to 35 degrees.

[0035] This embodiment is similar to the first embodiment, except that the first and second acute angles are set to 25 degrees. This adjustment allows the cutting device to have greater adaptability and flexibility when cutting softer or thinner battery connectors, while still maintaining high cutting accuracy and a smooth cutting surface.

[0036] Compared with the first and second embodiments, the first and second acute angles of this embodiment are set to 35 degrees. This angle design is suitable for cutting harder or thicker battery connectors, and can improve cutting efficiency and stability while ensuring cutting accuracy.

[0037] like Figure 3 As shown, based on the first embodiment, this embodiment further improves the upper mounting base 11. The bottom of the upper mounting base 11 is provided with an upper guide post 15 and an upper guide hole 16 to ensure the stability and accuracy of the upper cutting unit 1 during the cutting process. Furthermore, the side of the upper mounting base 11 is provided with an upper screw fixing hole 17, which is used to secure the upper guide post 15. This design allows for easy replacement of the upper guide post 15 if it becomes worn or deformed, thereby extending the service life of the cutting device.

[0038] like Figure 3 As shown, similar to the fourth embodiment, this embodiment features improvements to the lower mounting base 21. A lower guide post 25 and a lower guide hole 26 are provided on the top of the lower mounting base 21 to ensure stability and accuracy of the lower cutting unit 2 during the cutting process. Furthermore, lower screw holes 27 are provided on the side of the lower mounting base 21 for securing the lower guide post 25. This design also allows for easy replacement of the lower guide post 25 should it become worn or deformed, improving the reliability and durability of the cutting device.
