[0048] 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.

[0049] Please refer to Figure 1-3 This utility model provides an automatic battery cell packaging device, including a power unit 1, a battery cell placement platform 2, and a packaging film placement platform 3; wherein,

[0050] The power unit 1, the battery cell placement platform 2, and the packaging film placement platform 3 are arranged in sequence.

[0051] The cell placement platform 2 is used to place the cell 5 to be coated;

[0052] The packaging film placement platform 3 is used to place the packaging film 6;

[0053] The power unit 1 is used to apply a thrust to the battery cell 5 to push the battery cell 5 into the packaging film 6.

[0054] This embodiment, through the coordinated operation of the meticulously designed cell placement platform 2, packaging film placement platform 3, and power device 1, not only significantly improves the efficiency of applying five layers of film to the cells, but also ensures a high degree of consistency in the film application process through mechanized operation, greatly reducing errors that may be caused by human factors. This innovative design has significant positive implications for promoting standardized production of battery products, improving product quality, and driving their application in a wider range of fields.

[0055] In one embodiment of this invention, the power device 1 includes a push rod 11 and a power source;

[0056] The output end of the power source is connected to the push rod 11, ensuring the effective transmission of driving force;

[0057] The push rod 11 contacts the battery cell 5 so as to directly apply a pushing force to the battery cell 5 and complete the coating operation. Figure 2 This illustration shows the case where the battery cell 5 is not pushed into the packaging film 6. Figure 3 This illustrates the situation where the battery cell 5 pushes the packaging film 6.

[0058] It is worth noting that the specific form of the power source in this embodiment has multiple possibilities. For example, it can be a manually operated pusher that drives the push rod by applying force manually; it can also be a more automated motor that drives the reciprocating motion of the push rod through electricity; or it can be a cylinder that operates on the principle of pneumatics, driving the push rod to extend or retract through changes in air pressure. These diverse power source options not only enrich the applicable scenarios of the battery cell coating equipment, but also provide users with a more flexible and convenient operating experience.

[0059] In one embodiment of this invention, the design of the battery cell placement platform 2 and the packaging film placement platform 3 has been further optimized and improved. A battery cell placement groove 7 is specially provided on the battery cell placement platform 2. This design aims to more accurately position the battery cell 5 to be coated with film, ensuring its stable placement in the predetermined position. The length direction of the battery cell placement groove 7 is carefully set to be consistent with the direction of the thrust applied to the battery cell 5 by the power device 1. This layout not only facilitates the smooth transmission of thrust but also effectively prevents the battery cell from shifting or tilting during the coating process.

[0060] Similarly, a packaging film placement slot 8 is also provided on the packaging film placement platform 3 to regulate the placement position of the packaging film 6. The length direction of the packaging film placement slot 8 is also consistent with the thrust direction of the power unit 1, ensuring that the packaging film can unfold along the correct path during the film application process, avoiding waste or damage to the film material.

[0061] Furthermore, this embodiment specifically emphasizes that the height of the packaging film placement slot 8 is equal to the height of the battery cell placement slot 7. This design detail ensures that the battery cell 5 fits tightly with the packaging film 6 when it is pushed in, thereby further improving the accuracy and quality of the wrapping. Through this series of meticulous designs, the automatic battery cell wrapping equipment of this embodiment has achieved significant improvements in wrapping efficiency, consistency, and ease of operation.

[0062] In a more complete embodiment of this example, the automatic cell coating equipment is further equipped with a guide device 4 as a key component.

[0063] The guiding device 4 is cleverly positioned between the battery cell placement platform 2 and the packaging film placement platform 3. Its core function is to provide a precise guiding path during the pushing process of the battery cell 5, ensuring that the battery cell 5 can be accurately guided along this path into the interior of the packaging film 6.

[0064] This design not only further improves the accuracy and efficiency of cell coating, but also effectively avoids potential deviations or jamming during cell pushing, thus ensuring the stability and reliability of the coating operation. With the addition of the guide device 4, the automatic cell coating equipment in this embodiment achieves a higher level of automation and operational precision, providing stronger technical support for battery manufacturing.

[0065] In a specific and detailed embodiment of this invention, the structure of the guiding device 4 is disclosed in detail. The guiding device 4 mainly consists of two key parts: the upright plate 41 and the guiding structure 42. The two work together to complete the guiding task of the battery cell 5.

[0066] The upright plate 41 serves as the main support structure of the guide device 4, and a through hole 43 is carefully opened on it to allow the battery cell 5 to pass smoothly. The design of this through hole 43 not only ensures that the battery cell 5 can pass smoothly during the pushing process, but also provides it with a stable guiding reference.

[0067] The guide structure 42 is located on the side of the upright plate 41 facing the packaging film placement platform 3, and its design is more ingenious. The inlet of the guide structure 42 is precisely aligned with the through hole 43 on the upright plate 41, ensuring that the battery cell 5 can seamlessly enter the guide structure 42 after leaving the through hole 43. More importantly, the outlet of the guide structure 42 is cleverly designed to align with the inside of the packaging film 6. In this way, as the battery cell 5 is pushed through the guide structure 42, it can be accurately guided into the inside of the packaging film 6 to complete the wrapping operation.

[0068] With this carefully designed guide device 4, the automatic cell coating equipment in this embodiment achieves higher precision and stability in guiding and positioning the cells, further improving the quality and efficiency of the coating operation.

[0069] In one innovative and practical embodiment of this invention, the guide structure 42 is designed in a unique trumpet shape. This design is inspired by trumpet-shaped structures in nature, characterized by a wider inlet end and a narrower outlet end, creating a natural guiding and contraction effect.

[0070] Designing the guide structure 42 in a trumpet shape offers several advantages. First, the wider inlet end allows for easier reception of the battery cell 5, reducing friction and resistance between the cell and the guide structure during the pushing process, thus improving the smoothness and efficiency of the wrapping operation. Second, as the battery cell 5 gradually penetrates deeper into the guide structure 42, its gradually narrowing outlet end effectively positions and guides the cell. Since the outlet end extends into the packaging film 6, this ensures that the battery cell can be accurately guided into the packaging film 6, further enhancing the accuracy and stability of the wrapping process.

[0071] This innovative design not only reflects a deep understanding and superb skills in cell coating technology, but also brings a more efficient, accurate and reliable solution to battery manufacturing.

[0072] In a further optimization of this embodiment, the automatic battery cell wrapping equipment also includes an important component called a blocking device 9. The blocking device 9 is cleverly positioned behind the packaging film placement platform 3, and its key function is to effectively block the pushed battery cell 5, thereby preventing the battery cell 5 from accidentally coming off the packaging film 6 due to inertia or other pushing forces after the wrapping operation is completed.

[0073] This design not only further enhances the reliability and safety of the cell wrapping operation, but also ensures that each cell is completely and tightly wrapped in the packaging film, avoiding quality problems or safety hazards caused by cell detachment. With the addition of the blocking device 9, the automatic cell wrapping equipment in this embodiment achieves a higher level of stability in the wrapping operation and higher finished product quality, providing a more solid technical guarantee for battery manufacturing.

[0074] Although this application frequently uses terms such as power unit, battery cell placement platform, and packaging film placement platform, 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.

[0075] This utility model provides an automatic battery cell coating device. By setting up a battery cell placement platform for placing the battery cells to be coated, a packaging film placement platform for placing the packaging film, and a power device for applying a pushing force to the battery cells, the battery cells can be pushed into the packaging film, thereby realizing automatic coating. This not only improves the coating efficiency but also ensures the consistency of the coating, which is beneficial to the production and promotion of batteries.

[0076] 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.
