Technical Field
[0001] This utility model relates to the field of battery processing technology, and in particular to a tooling for sealing large cylindrical batteries. Background Technology
[0002] With the rapid development of new energy technologies, battery manufacturing processes are also constantly improving. In battery production, the overlay process is a crucial step in ensuring the structural stability and performance reliability of the battery. However, most existing overlay equipment is large-scale, complex in structure, and while highly efficient, it is not suitable for small-batch production scenarios on pilot or experimental lines.
[0003] In existing technologies, large-scale sealing equipment is typically used in large-scale production lines, and its design and function are primarily aimed at high-volume and high-efficiency production needs. While the complex structure of this equipment can meet the stability requirements of large-scale production, its shortcomings gradually become apparent during the small-batch trial and verification phase. Specifically:

[0012] In one embodiment of the present invention, the inner clamping mechanism includes two semi-circular arc fixtures arranged in parallel. The inner diameter of the semi-circular arc fixture matches the outer diameter of the battery cell. When the battery cell is placed in the inner clamping mechanism, the inner wall of the semi-circular arc fixture can tightly fit the surface of the battery cell.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.
[0026] Reference Figure 1 As shown, this utility model provides a large cylindrical battery sealing fixture, including: a support frame 1, a base 2, a battery clamping mechanism 3, and a sealing mechanism 4. The base 2 is located at the bottom of the support frame 1, the battery clamping mechanism 3 is located on the base 2 for fixing the battery cell, and the sealing mechanism 4 is located at the top of the support frame 1. The battery clamping mechanism 3 includes an inner clamping mechanism 31, a base 32, and an outer clamping mechanism 33. The inner clamping mechanism 31 is used to fix and clamp the battery cell, and the outer clamping mechanism 33 is fixedly located on the base 32 and encloses the inner clamping mechanism 31 to achieve secondary fixing of the battery cell.
[0027] This utility model achieves a compact layout by combining a support frame 1, a base 2, a battery clamping mechanism 3, and a sealing mechanism 4, reducing the floor space and improving space utilization. The coordinated use of the inner clamping mechanism 31 and the outer clamping mechanism 33 ensures greater stability of the battery cells during the sealing process, preventing cell displacement or damage due to insecure clamping, and significantly improving the reliability of the production process. This fixture can adapt to large cylindrical batteries of different models and sizes, and is particularly suitable for small-batch production on pilot or experimental lines, exhibiting high versatility and flexibility.
[0028] Preferably, the inner clamping mechanism 31 and the outer clamping mechanism 33 are detachably connected. This detachable connection design allows for quick replacement and maintenance of the inner clamping mechanism 31 and the outer clamping mechanism 33, reducing equipment downtime and extending equipment lifespan. Furthermore, it allows for rapid adjustment of the battery clamping mechanism 3 configuration according to different battery models and production needs, further enhancing the equipment's adaptability and versatility.
[0029] like Figure 2 As shown, the external clamping mechanism 33 includes a clamping seat 331, which has a U-shaped hole 332 for accommodating the internal clamping mechanism 31. The U-shaped hole 332 can be adjusted according to different battery models. The design of the U-shaped hole 332 allows for flexible adjustment according to the battery size, enabling the tooling to quickly adapt to battery cells of different diameters without frequent fixture changes, thus improving production efficiency. The structural design of the clamping seat 331 enhances the overall stability of the external clamping mechanism 33, ensuring a uniform distribution of clamping force during the sealing process and further improving the reliability of the equipment.
[0030] The clamping base 331 has U-shaped notches 333 on both sides of the U-shaped hole 332. The design of the U-shaped notches 333 allows for quick removal of the battery cells after sealing. This design reduces operation steps and time, improving the ease of use and production efficiency of the equipment. The structure of the U-shaped notches 333 reduces the amount of material used in the clamping base 331, thereby reducing the overall weight of the equipment. This lightweight design not only facilitates the handling and installation of the equipment but also reduces energy consumption, further improving the economic efficiency of the equipment.
[0031] like Figure 3 As shown, the inner clamping mechanism 31 includes two parallel semi-circular arc fixtures. The inner diameter of the semi-circular arc fixture matches the outer diameter of the battery cell. When the battery cell is placed inside the inner clamping mechanism 31, the inner wall of the semi-circular arc fixture can tightly fit the surface of the battery cell. The semi-circular arc fixture design of the inner clamping mechanism 31 can also tightly fit the surface of battery cells of different diameters. This adjustability allows the fixture to quickly switch between different battery models, greatly improving the versatility and flexibility of the equipment.
[0032] In this embodiment, the sealing mechanism 4 includes a cylinder 41, a connecting plate 42, and a pressure block 43. The cylinder 41 is located at the top of the support frame 1, the connecting plate 42 is located inside the support frame 1, the telescopic end of the cylinder 41 is connected to the connecting plate 42 through a fixing head 44, and the pressure block 43 is located on the connecting plate 42.
[0033] In this embodiment, the pressure block 43 is shaped to match the battery cell casing. Matching the shape of the pressure block 43 to the battery casing ensures maximum contact area during compression, further improving compression effect and stability. By optimizing the shape of the pressure block 43, excessive local compression of the cell casing is avoided, protecting the internal structure of the cell and extending battery life.
[0034] Furthermore, the support frame 1 is equipped with a set of guide columns 11, and the connecting plate 42 is slidably disposed on the outside of the guide columns 11. The design of the guide columns 11 ensures that the movement of the connecting plate 42 driven by the cylinder 41 is more stable, avoiding equipment failure or battery damage caused by movement deviation. In addition, the use of guide columns 11 improves the accuracy of the sealing process, ensuring that the pressing block 43 can accurately act on the predetermined position of the battery casing, further improving the reliability of the equipment.
[0035] In this embodiment, a linear bearing 12 is provided on the connecting plate 42, and the linear bearing 12 is sleeved on the outside of the guide column 11. The use of the linear bearing 12 significantly reduces the friction between the connecting plate 42 and the guide column 11, improving the operating efficiency and service life of the equipment. The linear bearing 12 ensures that the linear movement of the connecting plate 42 is smoother and more precise, further improving the stability and reliability of the pier sealing process.
[0036] Furthermore, a control switch 5 is provided on the base 2, which is used to control the opening and closing of the cylinder 41. The design of the control switch 5 allows the operator to quickly start or stop the cylinder 41, simplifying the operation process and improving the ease of use of the equipment. Through centralized control by the control switch 5, direct contact between the operator and the equipment is reduced, further improving the safety of the equipment.
[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
