[0032] Referring to FIG. 1 , an embodiment of the utility model provides a battery cell tab processing device, which includes a base frame 100, a driving mechanism 200, a bearing mechanism 300, a pressing mechanism 400 and a guiding mechanism 500; wherein the bearing mechanism 300 is located on one side of the pressing mechanism 400, and the bearing mechanism 300 is suitable for accommodating a battery cell 600 to be processed, and a tab 610 on the battery cell 600 extends between the pressing mechanism 400 and the bearing mechanism 300; the driving mechanism 200 and the guiding mechanism 500 are respectively arranged on the base frame 100, and are both connected to the pressing mechanism 400, and the driving mechanism 200 is used to drive the pressing mechanism 400 to move along the direction of the guiding mechanism 500 toward the bearing mechanism 300 until it abuts against the tab 610. Specifically in this embodiment, the guiding mechanism 500 is arranged in a direction perpendicular to the bearing mechanism 300, and the pressing mechanism 400 abuts and presses against the bearing mechanism 300 in a vertical direction under the drive of the driving mechanism 200.

[0033] Among them, the battery cell tab processing device adopts a combination of a base frame 100, a driving mechanism 200, a bearing mechanism 300, a pressing mechanism 400 and a guiding mechanism 500 to achieve effective processing of the battery cell tab. During the processing, the bearing mechanism 300 is responsible for ensuring that the welding point between the battery cell tab and the metal foil is accurately positioned on the lower pressing table. The driving mechanism 200 applies moderate force to process the metal burrs at the welding point of the battery cell tab. The special design of the pressing mechanism 400 allows it to abut against the bearing mechanism 300 in the processing state and stay away from the bearing mechanism 300 in the standby state. The guiding mechanism 500 guides the movement of the pressing mechanism 400 throughout the processing process to ensure that the metal burrs are evenly flattened. The combination of these components enables the device to avoid potential damage to the insulating tape by metal burrs during the processing of the battery cell tab, thereby improving the safety of the battery. Overall, the battery cell tab processing device effectively realizes the processing of metal burrs at the welding point through its structural design and component functions, providing a reliable solution for battery manufacturing.

[0034] In one embodiment, the pressing mechanism 400 includes a connecting member 410 slidably connected to the guide mechanism 500 and a pressing block 420 for abutting against the supporting mechanism 300 . One end of the connecting member 410 is connected to the driving mechanism 200 , and the other end of the connecting member 410 is connected to the pressing block 420 .

[0035] Specifically, the connector 410 cooperates with the guide mechanism 500 through a sliding connection, so that the pressing block 420 can move along a specific path during the processing. One end of the connector 410 is connected to the drive mechanism 200, and the movement control of the connector 410 is achieved through the action of the drive mechanism 200. The other end is connected to the pressing block 420 to ensure that the driving force can be effectively transmitted to the pressing block 420 so as to abut against the supporting mechanism 300 in the processing state. This design enables the connector 410 to move in an orderly manner with the pressing block 420 under the guidance of the guide mechanism 500 during the processing process to process the metal burrs at the welding of the battery cell tabs. At the same time, the tight connection of the connector 410 and the effective linkage of the drive mechanism 200 and the pressing block 420 help to ensure the stability and controllability of the processing process.

[0036] In general, the design of the pressing mechanism 400 in this embodiment can effectively achieve efficient processing of metal burrs at the welding of the battery cell tabs through the synergistic effect of the connector 410 and the guide mechanism 500. The flexible connection mode of the connector 410 enables the device to switch between the processing state and the standby state, thereby providing a reliable mechanism to help maintain the safety and performance of the battery.

[0037] Referring to FIG. 2 , in one embodiment, a slide bar 430 is provided on the pressing block 420, one end of the slide bar 430 is connected to the pressing block 420, and the other end passes through the connecting member 410, and a limit block 440 is provided on the other end of the slide bar 430, and the limit block 440 is suitable for abutting against the top surface of the connecting member 410 to limit the movement of the pressing block 420 away from the connecting member 410; an elastic member 450 is also abutted between the pressing block 420 and the connecting member 410.

[0038] Specifically, the slide bar 430 is connected to the pressing block 420, and it extends through the connecting member 410 through one end connected to the pressing block 420. The limit block 440 is arranged at the other end of the slide bar 430, and is suitable for abutting the top surface of the connecting member 410. Its function is to limit the movement of the pressing block 420 when the pressing block 420 moves in the direction away from the connecting member 410, specifically, by abutting the top surface of the connecting member 410, the movement of the pressing block 420 away from the connecting member 410 stops after reaching the limit. The elastic member 450 abuts between the pressing block 420 and the connecting member 410. Specifically in this embodiment, the elastic member 450 is sleeved on the outside of the slide bar 430, and the two ends of the elastic member 450 abut the pressing block 420 and the connecting member 410 respectively. The elastic member 450 provides a certain elastic support, which helps to absorb impact during the processing, thereby stabilizing the processing process. It should be noted that the elastic member 450 in this embodiment is specifically a spring, and it can also be other structures or devices that can produce elastic deformation, and this application does not make specific limitations on this.

[0039] By setting the slide bar 430 and the limit block 440, the movement of the pressing block 420 is effectively controlled and limited, which helps to ensure the accuracy of the processing. The presence of the elastic member 450 can provide a certain buffer and absorption during the processing, which helps to smooth the processing and reduce the impact on the tab. Such a structural design helps to improve the structural stability of the device and ensure that each component maintains a suitable position during the processing.

[0040] Referring to Figure 3, in one embodiment, the supporting mechanism 300 includes a positioning plate 310 and an abutment plate 320, the abutment plate 320 is arranged on a first side of the positioning plate 310, the first side is a side of the positioning plate 310 close to the pressing mechanism 400, the abutment plate 320 is staggered with the positioning plate 310, and is suitable for placing the pole ear 610 for pressing of the pressing block 420.

[0041] Specifically, when the battery cell 600 is placed on the positioning plate 310, the tab 610 on the battery cell 600 can fit with the top surface of the abutment plate 320 and maintain a horizontal state, so that the pressing block 420 can be accurately pressed on the tab 610, which helps to ensure the processing accuracy of the tab 610. The position of the abutment plate 320 is offset from the positioning plate 310 in the thickness direction of the battery cell, so that in the design of the bearing mechanism 300, the battery cell tab can be accurately and stably placed. In conjunction with Figure 3, it can be understood that the above-mentioned offset setting refers to the top surface of the abutment plate 320 being higher than the top surface of the positioning plate 310. This offset setting helps to ensure that the abutment plate 320 can provide sufficient support for the tab 610 and prevent the battery cell tab from becoming unstable during processing. The setting of the positioning plate 310 also helps to guide and position the battery cell tab to ensure the accuracy of its placement. Since the abutment plate 320 is disposed on the first side of the positioning plate 310 , the structural stability of the supporting mechanism 300 is further enhanced, and a reliable basis is provided for the subsequent pressing of the pressing block 420 .

[0042] During the processing of the cell tabs, the design of the support mechanism 300 enables the synergistic effect of the abutment plate 320 and the positioning plate 310 to effectively accommodate and stabilize the cell tabs, providing a solid foundation for subsequent processing steps. This design feature improves the accuracy and controllability of the device when processing the cell tabs, and helps to improve the efficiency and quality of cell tab processing.

[0043] In one embodiment, the bearing mechanism 300 further includes a plurality of first positioning structures 330, which are arranged on the second side and the third side of the positioning plate 310, the second side and the third side are respectively the two sides adjacent to the first side of the positioning plate 310, and the plurality of first positioning structures 330 and the positioning plate 310 together form a receiving cavity suitable for receiving the battery cell 600, and suitable for limiting the movement of the battery cell 600 in the first direction. Specifically in this embodiment, the first direction is the lateral direction of the battery cell, that is, the two adjacent sides of one side of the battery cell where the tab is arranged, and limiting the movement of the battery cell 600 in the first direction is to control the battery cell 600 not to produce lateral displacement, thereby controlling the tab within the pressing range of the pressing block 420.

[0044] Specifically, the first positioning structure 330 is arranged on different sides of the positioning plate 310 to form a positioning frame around the battery cell 600. This frame provides stable support in the first direction and limits the range of movement of the battery cell 600. This design helps to ensure that the battery cell 600 can be accurately positioned in the carrier mechanism 300, making the subsequent processing more accurate and controllable. The formation of the accommodating cavity provides a relatively stable and accurate placement space for the battery cell 600 through the synergistic effect of the first positioning structure 330 and the positioning plate 310. This is very critical for subsequent processing steps, especially during the pressing process of the pressing block 420, the battery cell 600 needs to be firmly supported at a specific position. The relative stillness of the battery cell in the first direction helps to maintain the stability of the processing process, prevent unnecessary deviation or shaking, and help prevent safety problems caused by accidental movement of the battery cell. By introducing restrictions on the first direction of the battery cell, the accuracy and stability of the battery cell processing are improved, which helps to ensure that the tab is controlled during the processing.

[0045] This design feature not only improves the accuracy and controllability of the supporting mechanism 300 in the battery cell processing, but also helps to ensure that the battery cell 600 maintains a relatively fixed position during the processing through the limiting effect of the first positioning structure 330 on the battery cell 600. Overall, the design of this embodiment helps to improve the efficiency and quality of battery cell processing.

[0046] In one embodiment, the supporting mechanism 300 further includes a plurality of second positioning structures 340, which are arranged on the first side of the positioning plate 310 and are suitable for limiting the movement of the battery cell 600 in the second direction. Specifically in this embodiment, the second direction is the direction in which the battery cell tabs are arranged, and limiting the movement of the battery cell 600 in the second direction is to control the extension length of the battery cell tabs.

[0047] The second positioning structure 340 is designed to provide additional support and positioning in the second direction to ensure that the battery cell 600 can be firmly restrained in the supporting mechanism 300. This restriction helps prevent unnecessary deviation or shaking of the battery cell 600 during processing, ensuring the accuracy and controllability of the processing process. These second positioning structures 340 and the positioning plate 310 together form a mechanism to limit the movement of the battery cell 600 in the second direction, providing more comprehensive stability for the battery cell 600. Such a design takes into account the movement characteristics of the battery cell 600 in different directions, making the entire processing process more accurate and reliable. By providing the second positioning structure 340 on the first side, the supporting mechanism 300 provides additional constraints in the second direction, which helps to keep the battery cell 600 in a relatively static state. This is crucial for the battery cell tabs that require high-precision processing.

[0048] In one embodiment, a plurality of mounting holes are provided on the positioning plate 310, and a plurality of first positioning structures 330 are connected to the positioning plate 310 through the mounting holes. The provision of the mounting holes allows the first positioning structures 330 to be accurately mounted on the positioning plate 310, and ensures that they are firmly and reliably connected to the positioning plate 310. This helps to maintain the fixed position of the first positioning structures 330 on the positioning plate 310, and ensures reliable support and positioning during the battery cell processing. By providing the mounting holes, the first positioning structures 330 can be flexibly adjusted and replaced to adapt to different battery cell sizes or processing requirements. The flexibility of this design helps to improve the versatility and applicability of the supporting mechanism 300.

[0049] In general, by providing mounting holes on the positioning plate 310, the way of mounting the first positioning structure 330 on the positioning plate 310 in this embodiment is more flexible and controllable. This design helps to ensure that the first positioning structure 330 can be firmly fixed in a suitable position during the battery cell processing, providing stable support and positioning for the battery cell 600.

[0050] In one embodiment, the positioning plate 310 is further provided with a clearance groove 350 on both side walls along the width direction thereof, and the clearance groove 350 penetrates along the thickness direction of the positioning plate 310. After the battery cell 600 is placed on the positioning plate 310, the projection of the clearance groove 350 can fall on the battery cell 600. The provision of the clearance groove 350 facilitates the removal of the battery cell 600 on the positioning plate 310.

[0051] In one embodiment, the pressing block 420 and the connecting member 410 are detachably connected. The detachable connection allows the pressing block 420 and the connecting member 410 to be easily disassembled when maintenance or replacement is required, without the need for large-scale disassembly of the entire device. This helps to improve the maintainability and reliability of the equipment. The detachable connection allows the connection between the pressing block 420 and the connecting member 410 to be adjusted or replaced according to different processing requirements. This flexibility helps to adapt to the processing of battery cell tabs of different specifications or types, and improves the adaptability of the equipment. The detachable connection facilitates the debugging and optimization of various components in the processing process. By disassembling the connection, the operator can more easily make the necessary adjustments to improve processing efficiency and quality.

[0052] In general, the detachable connection design in this embodiment provides more flexibility and convenience for the connection between the pressing block 420 and the connecting piece 410, thereby making the battery cell tab processing device more suitable for different production requirements and operation scenarios.

[0053] In one of the embodiments, a buffer layer is provided on the side where the pressing block 420 abuts against the pole lug 610. The buffer layer may be designed using various materials, such as rubber, elastic plastic or other materials with shock absorption and buffering properties. The purpose of this design is to reduce the impact on the battery cell 600 through the buffer layer during the processing of the battery cell pole lug and improve the smoothness of the processing. When the pressing block 420 contacts the battery cell pole lug, the buffer layer can slow down the impact force, thereby reducing the mechanical damage to the battery cell pole lug, and then play a certain buffering role in the extrusion of the pole lug 610, avoiding the pole lug 610 from being subjected to a large impact force and causing overall deformation. In addition, different sizes and shapes of battery cell pole lugs may require different processing parameters, and the presence of the buffer layer can improve the adaptability between the pressing block 420 and the pole lug 610, so as to be suitable for battery cells 600 of various specifications.

[0054] In one embodiment, the base frame 100 includes a base plate 110 and a stand 120 connected to each other, the bearing mechanism 300 is arranged on the base plate 110, and the guide mechanism 500 and the drive mechanism 200 are arranged on the stand 120. The base plate 110 is a part of the base frame 100, and as the underlying structure, provides overall stability and support. The bearing mechanism 300 is arranged on the base plate 110, ensuring that the battery cell 600 to be processed is reliably supported. The stand 120 is connected to the base plate 110, providing vertical structural support. The guide mechanism 500 and the drive mechanism 200 are respectively arranged on the stand 120, so that they can operate relatively independently without affecting the stability of the base plate 110. This structural design in which the base plate 110 and the stand 120 are connected to each other reasonably distributes the various key components in different positions to achieve the stability and efficiency of the entire battery cell tab processing device. This modular layout also helps to improve the maintainability and flexibility of the device, making the adjustment and replacement of different components more convenient.

[0055] In one embodiment, the guide mechanism 500 is a guide rail provided on the stand 120, and a guide groove cooperating with the guide rail is provided on the connector 410. Specifically, the guide groove is provided along the movement direction of the pressing block 420, and the connector 410 realizes directional sliding along the guide mechanism 500 through the cooperation between the guide groove and the guide rail. This directional sliding mechanism helps to ensure the accuracy and controllability during the processing, and improves the processing efficiency and processing quality of the device.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
