[0002] Batteries, as widely used and crucial charging and discharging devices, occupy a pivotal position in our daily lives and industrial production. Battery cells, as an indispensable component of batteries, directly affect the overall efficiency of the battery. However, in current production practices, due to inherent errors in the precision of production equipment and the combined effects of various other factors, some battery cells manufactured on assembly lines exhibit subtle deviations in size or shape from standard cells.

[0003] Of particular note are the extremely stringent dimensional requirements for battery cells, especially the diameter requirements for pouch polymer cells. Even the slightest dimensional deviation can cause the cell to fail to fit the product's pre-designed assembly space, leading to assembly failure. To address this issue, the industry commonly employs a reshaping process to ensure a high degree of consistency in diameter between different cells.

[0004] Unfortunately, existing forming equipment has significant shortcomings in terms of efficiency. Specifically, these devices can only perform forming operations on one cell at a time, which not only greatly limits the improvement of production efficiency but also adversely affects the overall production schedule.

[0005] Therefore, given the aforementioned problems, it is particularly important and urgent to improve and upgrade existing cell shaping technology.

[0048] Example 1

[0049] In view of the deficiencies of the existing technology, the applicant, based on years of practical experience and professional knowledge in the design and manufacturing of this field, and in conjunction with the application of theoretical principles, has actively conducted research and innovation in order to create a technology that can solve the deficiencies of the existing technology. After continuous research, design, and repeated prototype production and improvement, this utility model with practical value has finally been created.

[0050] Please refer to Figure 1-2 This utility model provides a cell shaping plate, which consists of two parts, an upper plate 11 and a lower plate 12, which are arranged in a vertically corresponding manner and work together to achieve the shaping operation of the cell.

[0051] Specifically, the bottom surface of the upper pressure plate 11, that is, the surface facing the lower pressure plate 12, is carefully designed with a first cell positioning groove 13. This design aims to accurately accommodate and fix the upper part of several cells, ensuring that the cells can maintain stable and accurate positioning during the shaping process.

[0052] Correspondingly, the top surface of the lower pressure plate 12, that is, the surface facing the upper pressure plate 11, is equipped with a second cell positioning groove 14. This groove corresponds to the first cell positioning groove 13, and its function is to accommodate and fix the lower half of the cell, thereby forming a perfect fit with the upper pressure plate 11 to jointly complete the overall shaping of the cell.

[0053] The core innovation of this embodiment lies in the design of a first cell positioning groove 13 and a second cell positioning groove 14 on the upper pressure plate 11 and lower pressure plate 12, respectively, capable of accommodating the upper and lower halves of several battery cells. This allows the device to simultaneously shape multiple battery cells in a single operation. This design not only significantly improves the efficiency of battery cell shaping but also drives a leap in overall production efficiency, laying a solid foundation for the large-scale, high-efficiency application of battery cell shaping operations.

[0054] In conclusion, the cell shaping pressure plate device provided by this utility model, with its unique design concept and excellent performance, will undoubtedly show broad application prospects and huge market potential in the field of cell shaping.

[0055] In one embodiment of this invention, the design details of the cell shaping pressure plate are further refined. Specifically, the first cell positioning groove 13 on the upper pressure plate 11 is not singular, but cleverly configured as at least two to meet the need for simultaneously shaping more cells. These first cell positioning grooves 13 are not randomly arranged, but are distributed at equal intervals to ensure that each cell receives uniform and stable pressure during the shaping process, thereby further improving the consistency and accuracy of the shaping effect.

[0056] Similarly, at least two second cell positioning slots 14 are provided on the lower pressure plate 12 to perfectly correspond to the first cell positioning slot 13 on the upper pressure plate 11. These second cell positioning slots 14 also adopt an equidistant distribution design to ensure that the cell can obtain uniform and stable support during the shaping process of the lower half, thus complementing the shaping effect of the upper half and jointly achieving comprehensive and precise shaping of the cell.

[0057] Through this design, the cell shaping platen device in this embodiment not only improves the shaping efficiency, but also demonstrates excellent performance in maintaining the consistency and accuracy of the shaping effect.

[0058] In one embodiment of this invention, the design of the cell shaping plate has been further optimized and upgraded. Specifically, the design of each first cell positioning slot 13 fully considers the arrangement and positioning requirements of the cells, enabling it to accommodate the upper parts of several cells sequentially in the same direction. This design not only ensures the stability of the cells during the shaping process but also greatly improves the shaping efficiency, as multiple cells can be processed simultaneously without having to process them one by one.

[0059] Similarly, each of the second cell positioning slots 14 adopts a similar design concept, that is, to accommodate the lower half of several cells sequentially in the same direction. In this way, when the upper pressure plate 11 and the lower pressure plate 12 are combined, the upper and lower halves of each cell can be precisely aligned and obtain uniform and stable pressure during the shaping process.

[0060] Through this design, the cell shaping platen device in this embodiment not only achieves simultaneous shaping of multiple cells, but also ensures the consistency and accuracy of the shaping effect. Furthermore, since the cells are arranged sequentially in the same direction, it facilitates subsequent collection and sorting, further improving production efficiency.

[0061] In one embodiment of this invention, the shape of the cell positioning groove in the cell shaping plate is carefully designed. Specifically, each of the first cell positioning grooves 13 is designed as a semi-circle, a shape that perfectly matches the contour of the upper half of the cell, thereby ensuring the stability and accuracy of the cell during the shaping process. The semi-circular design not only helps in the precise positioning of the cell but also provides a uniform and stable pressure distribution to the cell during the shaping process, further improving the shaping effect.

[0062] Similarly, each of the second cell positioning slots 14 is also designed to be semi-circular, matching the contour of the lower half of the cell. Thus, when the upper pressure plate 11 and the lower pressure plate 12 are joined, the first cell positioning slot 13 and the second cell positioning slot 14 together form a complete circular space, completely enclosing the cell. This design not only facilitates the overall shaping of the cell but also ensures that the cell is not subjected to any unnecessary damage during the shaping process.

[0063] Through this design, the cell shaping platen device in this embodiment not only achieves precise cell shaping but also ensures the safety and reliability of the shaping process. Furthermore, the semi-circular cell positioning groove design allows the cells to be easily removed from the platen after shaping, further improving production efficiency.

[0064] In one embodiment of this invention, a guide post 15 is provided on the surface of the upper pressure plate 11 facing the lower pressure plate 12;

[0065] The lower pressure plate 12 has a guide hole 16 on its surface facing the upper pressure plate 11, which cooperates with the guide post 15. That is, the shape, size and position of the guide hole 16 are matched with the guide post 15 to ensure that the guide post 15 can be smoothly inserted into the guide hole 16 when the pressure plates are merged, thereby achieving precise positioning and alignment of the pressure plates.

[0066] It should be noted that this design is intended to ensure the precise alignment of the upper pressure plate 11 and the lower pressure plate 12 during the merging process, thereby preventing the battery cell from being damaged due to misalignment of the pressure plates during the shaping process.

[0067] Through this design, the cell shaping platen device of this embodiment can maintain high stability and accuracy during the shaping process. The cooperation between the guide post 15 and the guide hole 16 not only helps to avoid unnecessary damage to the cell during the shaping process, but also ensures that the cell can obtain a consistent and uniform shaping effect after shaping.

[0068] Furthermore, the design of the guide post 15 and guide hole 16 makes the merging and separation of the upper pressure plate 11 and the lower pressure plate 12 smoother, further improving production efficiency. This innovative design will undoubtedly bring a more efficient and reliable solution to the field of cell shaping, promoting technological progress and application development in this field.

[0069] Although this application frequently uses terms such as "upper pressure plate" and "lower pressure plate," the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.

[0070] This utility model provides a battery cell shaping plate, which provides a first battery cell positioning groove on the surface of the upper plate that can accommodate the upper half of several battery cells, and a second battery cell positioning groove on the surface of the lower plate that can accommodate the lower half of several battery cells. This allows several battery cells to be shaped at the same time, thereby greatly improving the leveling efficiency and production efficiency, which is conducive to widespread application.

[0071] Example 2

[0072] Please refer to Figure 3-4 Embodiment 2 of this utility model provides an automatic battery cell shaping device, including a drive unit 20 and a battery cell shaping plate 10 as provided in Embodiment 1 above;

[0073] The cell shaping plate 10, as the core shaping component of this equipment, is ingeniously designed and practical, capable of simultaneously accommodating and shaping multiple cells, significantly improving shaping efficiency. This plate consists of an upper plate 11 and a lower plate 12, which, through precise cooperation, enable comprehensive and uniform shaping of the cells.

[0074] The driving component 20 serves as the power source for this device, and its driving end is tightly connected to the upper pressure plate 11. Under the action of the driving component 20, the upper pressure plate 11 can move vertically relative to the lower pressure plate 12, thus realizing the lifting and lowering action of the upper pressure plate 11. This design not only makes the cell shaping process more automated and efficient, but also ensures the stability and accuracy of the shaping process.

[0075] Once the battery cell is placed in the corresponding position on the battery cell shaping plate 10, the drive unit 20 starts working, driving the upper plate 11 to slowly descend until it makes close contact with the lower plate 12. During this process, the battery cell is subjected to uniform pressure from the upper plate 11 and the lower plate 12, thereby achieving precise adjustment of its shape and size. After shaping is completed, the drive unit 20 starts again, driving the upper plate 11 to rise, so as to remove the shaped battery cell.

[0076] Through this design, the automatic cell shaping equipment of this invention not only achieves a high degree of automation and efficiency in the cell shaping process, but also ensures the consistency and accuracy of the shaping results. This innovative equipment will undoubtedly bring a more efficient and reliable solution to the cell manufacturing field, promoting technological progress and application development in this field.

[0077] In conclusion, the automatic cell shaping equipment of this utility model, with its unique design concept and excellent performance, will undoubtedly show broad application prospects and huge market potential in the field of cell manufacturing.

[0078] In one embodiment of this invention, the driving component 20 is a booster cylinder.

[0079] It should be noted that the booster cylinder is a new type of drive device that integrates hydraulic and pneumatic systems. It combines the stability of a hydraulic system with the flexibility of a pneumatic system, and has the advantages of small size, light weight, large output, easy installation, and easy maintenance.

[0080] Using the booster cylinder as a driving component 20 in the automatic cell shaping equipment can fully leverage its characteristics of high output and fast response speed, ensuring that the upper pressure plate 11 can move smoothly and quickly relative to the lower pressure plate 12 in the vertical direction, thereby achieving efficient and precise shaping of the cell. In addition, the easy installation and maintenance of the booster cylinder also greatly reduces the operating cost and maintenance difficulty of the automatic cell shaping equipment.

[0081] Through this design, the automatic cell shaping equipment in this embodiment maintains high-efficiency shaping while also possessing good stability and reliability. The selection of the booster cylinder not only improves the overall performance of the equipment but also enables it to maintain a stable shaping effect during long-term use, further extending the equipment's service life.

[0082] In one embodiment of this invention, the automatic cell shaping equipment further includes a workbench 30 and a machine control unit 40, which together form a highly integrated and intelligent cell shaping system.

[0083] The drive unit 20, the cell shaping plate 10 and the machine control unit 40 are all mounted on the workbench 30;

[0084] The machine control unit 40 is connected to the drive component 20 and is used to control the start and stop of the drive component 20.

[0085] It should be noted that the workbench 30, as the support platform for the entire equipment, is designed to be robust and stable, capable of supporting all key components such as the drive unit 20, the cell shaping plate 10, and the machine control unit 40, ensuring the stability and reliability of the equipment during long-term operation. At the same time, the workbench 30 also provides a user-friendly interface and ample working space, making the operation and maintenance of the equipment simpler and more efficient.

[0086] The machine control unit 40, as the intelligent control center of the equipment, uses advanced control algorithms and a sophisticated sensor system to monitor the equipment's operating status in real time and precisely control the drive component 20 according to preset shaping parameters. Through the intelligent management of the machine control unit 40, the equipment can achieve multiple functions such as automatic start / stop, pressure regulation, and speed control, thereby ensuring the accuracy and efficiency of the cell shaping process.

[0087] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
