[0059] Please refer to Figure 1-3 The embodiment of the present invention provides an automatic cutting device for battery tabs, comprising a feeding device 1 and a cutting device 2; wherein,

[0060] The feeding device 1 is responsible for accurately transferring the battery cells to be cut from the upper and lower material positions to the cutting position, and returning the battery cells from the cutting position to the upper and lower material positions after the cutting is completed. Figure 1-2 The diagram shows the situation where the feeding device 1 does not carry a battery cell. Figure 3 The diagram shows the feeding device 1 carrying the battery cells; Figure 1 and Figure 3 The diagram shows the feeding device 1 being located at the upper and lower material positions. Figure 2 The diagram shows the situation where the feeding device 1 is located at the cutting position.

[0061] The cutting device 2 includes a first cutting mechanism 21 and a second cutting mechanism 22. The two cutting mechanisms are respectively arranged on opposite sides of the feeding device 1 and precisely correspond to the positions of the cutting positions.

[0062] The main function of the first cutting mechanism 21 is to cut off the tab at one end of the battery cell, while the second cutting mechanism 22 is responsible for cutting off the tab at the other end of the battery cell.

[0063] This embodiment cleverly designs the feeding device 1, enabling it to drive the battery cells to reciprocate between the upper and lower feeding positions and the cutting position. Simultaneously, in combination with the cutting device 2 comprising a first cutting mechanism 21 and a second cutting mechanism 22, when the battery cells are precisely transported to the cutting position, the two cutting mechanisms can act on both ends of the battery cells, achieving automated cutting of the tabs. This design not only significantly improves the efficiency of tab cutting, thereby promoting overall production efficiency, but also ensures consistency in the cutting process, which is of great significance for the production quality control of battery products and their subsequent promotion and application.

[0064] Please refer again Figure 1-3 , and combined with reference Figure 4-5 , in one implementation of this embodiment, the feeding device 1 includes a carrying block 11 and a conveying mechanism 12;

[0065] Specifically, the carrier block 11 is securely mounted on the conveyor mechanism 12. Its primary function is to serve as a support platform for the cells, ensuring they remain stable throughout the entire conveying process. This design takes into account both the physical properties of the cells and the stringent precision requirements of the cutting process.

[0066] The conveyor mechanism 12 acts as both a driver and a guide. Its mechanical structure and power unit precisely drive the carrier block 11 and the cells it carries, achieving smooth and efficient reciprocating motion between the upper and lower material positions and the cutting position. This precise positioning and transport of the cells paves the way for subsequent cutting operations.

[0067] Figure 4 The diagram shows the feeding device 1 being located at the upper and lower material positions. Figure 5 The diagram shows the situation where the feeding device 1 is located at the cutting position.

[0068] In summary, through the organic combination of the carrier block 11 and the conveying mechanism 12, the feeding device 1 can ensure the precise positioning and efficient conveying of battery cells during the cutting operation, thereby greatly improving the automation and efficiency of battery cell tab cutting. This design not only meets the dual requirements of efficiency and precision in modern industrial production, but also provides strong support for the further development of battery cell cutting technology.

[0069] In one embodiment of this invention, the structure of the conveying mechanism 12 is described in more detail. The conveying mechanism 12 is mainly composed of three key components: a slide rail, a slider, and a conveying power source. These components work together to achieve the precise conveying of battery cells between the upper and lower material positions and the cutting position.

[0070] The slide rail, as the basic support structure of the conveying mechanism 12, provides a stable and precise guide. Its design takes into account the accuracy and stability requirements of the battery cell conveying, ensuring the smooth and reliable movement of the slider on it.

[0071] The slider is cleverly positioned above the rails. It forms a close fit with the rails, enabling precise and smooth sliding under the guidance of the rails. Simultaneously, the slider also bears the heavy responsibility of supporting the block 11 and the cells thereon, ensuring the stability and safety of the cells throughout the entire transport process.

[0072] The conveying power source is key to driving the slider and carrier block 11 along the rails. It utilizes its own energy output to provide continuous and stable driving force for the slider, enabling precise reciprocating motion on the rails. During this process, the battery cells are stably transported to the cutting position and safely returned to the loading and unloading positions after cutting is complete, providing strong support for the subsequent battery production process.

[0073] In summary, through the careful design and coordinated operation of the slide rails, sliders and conveying power source, the conveying mechanism 12 achieves precise conveying and efficient positioning of the battery cells during the cutting operation.

[0074] In a specific implementation detail of this embodiment, the design of the carrier block 11 is further optimized. In order to more stably and accurately carry the battery cells, this embodiment specifically provides a placement slot 13 on the carrier block 11 for placing the battery cells.

[0075] The shape, size, and position of the placement slots 13 are carefully designed to ensure that the battery cells can be securely placed on the carrier block 11 and remain fixed during transportation. This design not only improves the stability of battery cell transportation, but also effectively prevents the battery cells from shaking or shifting during transportation, thereby ensuring the accuracy and efficiency of battery cell tab cutting.

[0076] At the same time, the provision of the placement slot 13 also facilitates the rapid positioning and placement of the battery cells, further improving the degree of automation of the battery cell cutting operation.

[0077] In one implementation of this embodiment, there are at least two placement slots 13;

[0078] At least two of the placement slots 13 are distributed at intervals.

[0079] It should be noted that this design offers multiple advantages. First, the provision of multiple placement slots 13 means that the carrier block 11 can simultaneously support multiple battery cells, significantly improving the batch processing capacity of the battery cell cutting operation. This is of great significance for improving production efficiency and reducing production costs.

[0080] Secondly, the spaced placement slots 13 ensure that each battery cell can obtain sufficient support and stability during transportation. This design avoids mutual interference between battery cells and ensures the accuracy and consistency of battery cell tab cutting.

[0081] In addition, the spacing distribution of the multiple placement slots 13 also helps to optimize the spatial layout of the battery cells during the transportation process, allowing the transportation mechanism 12 to more efficiently utilize space resources, further improving the degree of automation and flexibility of the battery cell cutting operation.

[0082] In one embodiment of this invention, the dimensions of the placement slot 13 are precisely designed to ensure that they perfectly match the length of the battery cell body. Specifically, the length of the placement slot 13 is set to be equal to the length of the battery cell body. This design allows the battery cell to be firmly embedded in the placement slot 13 without shaking or shifting during transportation.

[0083] Even more clever is that when the battery cell is correctly placed in the placement groove 13, the tabs at both ends will naturally be exposed outside the placement groove 13. This design not only ensures that the battery cell tabs can be removed during the cutting operation, but also avoids unnecessary contact between the battery cell body and the cutting tool, thereby protecting the integrity of the battery cell body.

[0084] Furthermore, the design of the placement slot 13 also helps improve the accuracy and consistency of the cell cutting operation. Due to the stable positioning of the cell in the placement slot 13, the cutting tool can more accurately find and cut the tab, thereby reducing cutting errors and improving the quality of the cell tab cutting.

[0085] In summary, by precisely planning the length of the placement slot 13 and cleverly designing the positioning of the battery cells within the slot 13, stable cell loading, precise positioning, and efficient cutting are achieved during the cutting process. This design not only improves the efficiency and quality of the cell cutting operation, but also provides strong support for automated, intelligent, and efficient battery production.

[0086] Please refer to Figure 6 In one implementation of this embodiment, the first cutting mechanism 21 and the second cutting mechanism 22 both include an upper cutting knife 211, a lower cutting seat 212 and a cutting power source 213 to ensure that the cutting operation of the battery cell tab can be completed efficiently and accurately.

[0087] Specifically, the upper cutting blade 211 and the lower cutting seat 212 are cleverly designed to correspond to each other in an upper and lower arrangement. This layout not only ensures the smooth cutting action, but also improves the safety of the cutting operation. During the cutting process, the upper cutting blade 211, driven by the cutting power source 213, will move along a predetermined trajectory toward or away from the lower cutting seat 212. When it is necessary to cut the battery cell tabs, the upper cutting blade 211 will quickly press down, forming a tight fit with the lower cutting seat 212, thereby accurately cutting the tabs at both ends of the battery cell.

[0088] The cutting power source 213, a key component driving the upper cutting blade 211, has a performance and stability that directly impacts the efficiency and quality of the cutting operation. In this embodiment, a high-performance motor or pneumatic device is used as the cutting power source 213 to ensure that the upper cutting blade 211 can quickly and stably complete the cutting operation.

[0089] Furthermore, to further improve the accuracy and consistency of cell tab cutting, this embodiment meticulously optimizes the structure and materials of the cutting mechanism. For example, the contact surfaces of the upper cutting blade 211 and the lower cutting seat 212 are both polished with high precision to ensure a smooth and even cutting surface. Furthermore, high-strength, wear-resistant materials are selected for the key components of the cutting mechanism to extend their service life and reduce maintenance costs.

[0090] Please refer again Figure 1-3 In one implementation of this embodiment, the battery cell tab automatic cutting device further includes a displacement device 3; the design of the displacement device 3 is intended to further improve the degree of automation and operating efficiency of battery cell tab cutting.

[0091] Specifically, the displacement device 3 is composed of two core components: a first displacement mechanism 31 and a second displacement mechanism 32. These two displacement mechanisms are closely connected to the first cutting mechanism 21 and the second cutting mechanism 22, respectively, and jointly bear the task of driving the cutting mechanisms to move closer to or away from the battery cell.

[0092] When the battery cell to be cut is precisely delivered to the cutting position, the first displacement mechanism 31 responds quickly, driving the first cutting mechanism 21 along a predetermined trajectory toward the battery cell. During this process, the first cutting mechanism 21 gradually enters a cutting preparation state, fully preparing for subsequent cutting operations. Similarly, the second displacement mechanism 32 simultaneously drives the second cutting mechanism 22 toward the battery cell, ensuring that both cutting mechanisms can simultaneously and accurately cut the tabs at both ends of the battery cell.

[0093] After the cutting operation is completed, the first displacement mechanism 31 and the second displacement mechanism 32 will respectively drive the first cutting mechanism 21 and the second cutting mechanism 22 away from the battery cell, thereby releasing the cutting preparation state. This design not only ensures the stability and safety of the cutting mechanism during operation, but also improves the continuity and efficiency of the battery cell cutting operation.

[0094] It's worth noting that the design of displacement mechanism 3 fully considers the practical needs and characteristics of battery cell cutting operations. For example, the displacement mechanism utilizes a high-precision, highly stable transmission device to ensure the accuracy and consistency of the cutting mechanism during movement. Furthermore, the displacement mechanism is equipped with an advanced control system that enables precise control of the cutting mechanism's motion trajectory, further improving the accuracy and efficiency of battery cell tab cutting.

[0095] Although the terms "feeding device" and "cutting device" are frequently used in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.

When the battery cell is conveyed to the cutting position, the first cutting mechanism and the second cutting mechanism can respectively cut off the tabs at the corresponding ends of the battery cell, thereby realizing automatic cutting of the battery cell tabs, which not only improves the efficiency of tab cutting and thus improves production efficiency, but also ensures the consistency of tab cutting, which is beneficial to the production and promotion and application of batteries.

[0097] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application.
