Description

Technical Field

[0001] This invention belongs to the field of electrode strip processing equipment, specifically an automated electrode strip riveting, spot welding and punching integrated equipment. Background Technology

[0002] As a key component of energy storage batteries, the dimensional accuracy of electrode strips and the quality of riveting directly affect the assembly performance and safety of the finished battery. Existing solutions, such as the one disclosed in Chinese Patent No. CN215431997U, "An Electrode Strip Spot Welding Machine," require welding a terminal to the end of the electrode sheet to meet subsequent usage requirements. However, this method has problems such as the risk of the terminal falling off during use, high cost of additional welding of the terminal, and unnecessary wear and tear on the terminal during processing. Therefore, a low-cost electrode sheet structure has emerged on the market to solve the above problems. This involves folding the end of the electrode sheet to form a multi-layered stacked structure, spot welding and fixing the structure, and punching holes, thus replacing the original function of setting up an additional terminal with an integrated electrode strip structure.

[0003] The current electrode strip forming process for this type of configuration involves multiple independent processes, including raw material feeding, riveting and assembly, weld point reinforcement, end punching, and finished product unloading and packaging. This is an essential processing flow for mass production of electrode strips. Currently, most mass production of electrode strips in the industry adopts a process-discretionary production layout, where the feeding station, riveting station, spot welding station, punching station, and finished product packaging station are each arranged as independent single machines in different positions on the production line. Workpieces are transferred between these single machines manually or by independent conveyor mechanisms. Different processes are completed step by step. This discrete processing mode has obvious drawbacks: The transfer of workpieces between multiple devices requires a lot of transfer time, the interval between process connections is long, the production rhythm of the entire production line is loose, the production efficiency is low, and the multiple devices are set up separately, making it difficult to coordinate and match the start and stop rhythm of each station, resulting in poor process continuity, difficulty in controlling the production rhythm, and easy problems such as material blockage and material shortage in the preceding and following processes, which is not conducive to large-scale continuous production.

[0004] In addition, existing riveting stations generally rely on simple side stops for single-sided positioning when riveting the ends of electrode strips, lacking a combined lateral and axial positioning structure. When the riveting head presses down, the electrode strip is easily subjected to riveting pressure impact, resulting in lateral slippage and end misalignment, causing the riveting position to be skewed, poor forming, and a high product scrap rate.

[0005] Moreover, in order to ensure accurate positioning and uniform distribution between layers after riveting, the electrode strip ends need to be accurately clamped at a specified position. This places high demands on the positional accuracy of the electrode strip and requires effective positioning of the electrode strip ends, which is difficult to achieve in current solutions. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention addresses the technical problem of simultaneously and collaboratively performing electrode strip processing actions. Different electrode strips can be loaded, riveted, spot-welded, punched, and packaged simultaneously, effectively saving time spent on transfers between multiple processes and greatly improving processing efficiency. Furthermore, the integration of each processing step onto the same equipment enhances the continuity between them, facilitating better control of the processing cycle. By setting wedge-shaped limiting blocks and inclined grooves, the electrode strip is first fixed by the wedge-shaped limiting blocks before the riveting head directly presses against its end, embedding it within the inclined grooves. This also provides effective lateral limiting and fixing of the electrode strip, preventing misalignment or displacement of the electrode strip end during pressing, which would otherwise result in poor pressing performance. By setting a limiting top bar that can slide along the length of the electrode strip within the riveting table, the precise adjustment of the limiting top bar's position, with its end abutting against the electrode strip end, achieves accurate and stable positioning of the electrode strip, thereby improving processing precision and finished product quality.

[0018] (2) By setting a wedge-shaped limiting block and a slanted groove, before the riveting head directly presses the end of the electrode strip, the electrode strip is first pressed by the wedge-shaped limiting block to fix the electrode strip and make the electrode strip embedded in the slanted groove. This also provides effective lateral limiting and fixing of the electrode strip, avoiding problems such as misalignment or displacement of the electrode strip end during the pressing process, which would result in poor pressing effect.

[0032] Explanation of reference numerals in the attached figures: Detailed Implementation

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] like Figure 1-12 As shown, an automated electrode strip riveting, spot welding, and punching integrated equipment includes a cabinet I, a panel II fixedly connected to the cabinet I, and punching components V, spot welding components VI, and riveting components VII arranged sequentially on the panel II. A material transfer component VIII is located on one side of the punching component V, spot welding component VI, and riveting component VII for feeding, carrying, and transferring finished electrode strips a. The electrode strips are conveyed and transferred by the material transfer component VIII, allowing them to be processed sequentially by the riveting component VII, spot welding component VI, and punching component V. The resulting finished electrode strip a ultimately has a folded riveting part b, a weld point c, and a punching hole d at its end. A storage platform IX is located at the end of the processing stroke on the panel II.

[0035] By sequentially setting up the riveting component VII, the spot welding component VI, and the punching component V, the end of the electrode strip can be processed in sequence. The end of the electrode strip is first folded and riveted at the riveting component VII to form a folded riveted part b, and then the spot welding component VI processes the weld point c at this position. Then, the weld point c is formed again at the punching component V, and finally, a finished electrode strip a that meets the usage requirements is obtained. This process is automatically changed by the material transfer component VIII to change the processing position and the feeding action. At the same time, the punching component V, the spot welding component VI, and the riveting component VII process multiple electrode strips simultaneously, which greatly improves the degree of automation, increases processing efficiency, and reduces wasted time.

[0036] like Figure 1-12As shown, the material transfer component VIII includes five placement seats 817, which are evenly spaced on the panel II. Each placement seat 817 is provided with a second flat plate 818 for supporting and placing electrode strips. The main working positions of the punching component V, the spot welding component VI, and the riveting component VII correspond to the positions of one of the second flat plates 818, respectively. Each placement seat 817 is fixedly provided with a positioning claw 819, and the claw of each positioning claw 819 is positioned on the second flat plate 818. On both sides, above the second flat plate 818, there is a crossbeam 814 that can be freely raised, lowered and moved. At the bottom of the crossbeam 814, at the corresponding position of each second flat plate 818, there is a suction cup seat 815. Each suction cup seat 815 is equipped with multiple suction cups 816. At the end of the stroke of the transfer component VIII, there is a transfer stacking platform 821 on the panel II for temporarily stacking electrode strips. The transfer lifting platform 808 is equipped with multiple vacuum source components 820 to assist the operation of the suction cups 816.

[0037] By setting up a crossbeam 814, a suction cup seat 815, and a suction cup 816, the electrode strip can be transferred between each of the second flat plates 818 by using the suction cup 816 to gradually advance the electrode strip for processing. The transfer process is stable and efficient. Finally, the suction cup seat 815 and the suction cup 816 at the end of the stroke transfer the finished electrode strip a after all processing to the transfer stacking platform 821 for temporary stacking.

[0038] Meanwhile, after each electrode strip is placed on the corresponding second flat plate 818, the positioning jaws 819 clamp and position the electrode strip on both sides to avoid the electrode strip from shifting or misaligning during processing, especially to prevent the main body of the electrode strip from warping or bending during riveting.

[0039] like Figure 1-12 As shown, a column 807 is provided on one side of the placement seat 817. A material transfer lifting platform 808 is slidably provided on the column 807. A material transfer horizontal transfer platform 811 is slidably provided at the bottom of the material transfer lifting platform 808 perpendicular to the length direction of the placement seat 817. The material transfer horizontal transfer platform 811 is fixedly connected to the end of the crossbeam 814. A material transfer vertical screw 809 is rotatably provided on the column 807 and threadedly connected to the material transfer lifting platform 808. A first material transfer motor 810 is provided at the top of the column 807 and drivenly connected to the material transfer vertical screw 809. A material transfer horizontal transfer screw 812 is rotatably provided on the material transfer horizontal transfer platform 811 and threadedly connected to the material transfer lifting platform 808. A second material transfer motor 813 is provided on the material transfer horizontal transfer platform 811 and drivenly connected to the material transfer horizontal transfer screw 812.

[0040] The lifting and lowering action of the crossbeam 814 is achieved by setting up the column 807 and the vertical transfer screw 809, while the horizontal movement of the crossbeam 814 is achieved by setting up the horizontal transfer platform 811 and the horizontal transfer screw 812. This allows the movements in the two directions to cooperate and superimpose, so that the electrode strip is picked up from the previous second flat plate 818 by the suction cup 816 and then transferred to the next second flat plate 818 and released, thus completing the electrode strip transfer action.

[0041] like Figure 1-12 As shown, a feeding rack 801 parallel to the placement seat 817 is provided on the panel II on one side of the riveting component VII. The feeding rack 801 has pulleys 803 rotatably mounted at both ends. A conveyor belt 804 is mounted on the outside of the pulleys 803. A conveyor motor 805 connected to the pulleys 803 is provided at one end of the feeding rack 801. A first flat plate 802 for supporting the conveyor belt 804 and the electrode strip is fixedly mounted on the feeding rack 801. A baffle 806 is provided on the feeding rack 801 at one end near the riveting component VII.

[0042] By setting up a conveyor belt 804, the preceding process can be connected to transport the electrode strip to be processed into this device. The first flat plate 802 serves to support the conveyor belt 804, preventing the position of the conveyor belt 804 used to transport the electrode strip from sagging under the action of gravity, thereby improving the stability of the transport. At the same time, by setting up a baffle 806, the electrode strip can be prevented from being transported on the conveyor belt 804. After the electrode strip is transported to the designated position, 80 is used to abut against the end of the electrode strip, thereby positioning the initial position of the electrode strip and ensuring the accuracy of the electrode strip position. In this embodiment, a photoelectric sensor can preferably be installed above the baffle 806 to detect whether the electrode strip has been transported to the correct position. When the detection result returns yes, the conveyor motor 805 is controlled to turn off and stop the transport of the electrode strip.

[0043] like Figure 1-12As shown, the riveting component VII includes a riveting frame 701, a riveting lifting seat 702 is provided inside the riveting frame 701, a riveting electric drive cylinder 703 is provided on the top of the riveting frame 701, the rod head of the riveting electric drive cylinder 703 passes through the top of the riveting frame 701 and is fixedly connected to the riveting lifting seat 702, a riveting head 704 is fixedly connected to the bottom of the riveting lifting seat 702, and a riveting table 709 is provided at the bottom of the riveting frame 701 at the position corresponding to the riveting head 704. Side frame blocks 710 for limiting the two sides of the electrode strip are provided on both sides of the riveting table 709. A clearance space 712 is provided at the position corresponding to the riveting head 704. A bottom support block 713 is slidably arranged in the clearance space 712. A second rotating jaw 715 is provided on the riveting frame 701 at the opposite position of the bottom support block 713. A first push cylinder 716 is provided on the riveting frame 701 to push the second rotating jaw 715. A tile-shaped jaw 723 is provided at the end of the second rotating jaw 715. A ramp 714 is provided at the end of the bottom support block 713. A second push cylinder 717 is provided on the riveting frame 701 to push the bottom support block 713.

[0044] By setting the second rotating jaw 715 and the tile-shaped jaw 723, the end of the electrode strip extending into the riveting table 709 can be clamped, and the end of the electrode strip can be rotated and twisted so that the end of the electrode strip is wrapped around the outside of the tile-shaped jaw 723 to form a spiral coiled part. The single tile-shaped jaw 723 is tile-shaped, which allows the end of the electrode strip to be wrapped more closely around the outside of the tile-shaped jaw 723. Then the tile-shaped jaw 723 is released and withdraws laterally.

[0045] During winding, the bottom support block 713 is located on one side of the electrode strip and the second rotating jaw 715, leaving enough space to facilitate the winding operation. The bottom support block 713 pushes the bottom of the spiral structure formed by the twisting of the electrode strip end to support it. Then, the riveting head 704 is controlled to press down on the spiral structure until the spiral structure is completely flattened, forming a multi-layered overlapping and folding riveting part b. In this way, the end of the electrode strip can be structurally reinforced without additional accessories, and the riveting operation is completed.

[0046] like Figure 1-12 As shown, a riveting limit seat 705 is fixedly installed on the riveting head 704, and a limit slide rod 706 is slidably installed on the riveting limit seat 705. A wedge-shaped limit block 708 located between the two side frame blocks 710 is fixedly connected to the bottom end of the limit slide rod 706. A spring 707 is provided between the riveting limit seat 705 and the wedge-shaped limit block 708, which surrounds the outside of the limit slide rod 706. A groove 711 is opened on the surface of the riveting table 709 at the corresponding position of the wedge-shaped limit block 708. The slope of the bottom slope of the wedge-shaped limit block 708 is consistent with the slope of the groove 711.

[0047] By setting the wedge-shaped limiting block 708 and the inclined groove 711, the electrode strip is first pressed by the wedge-shaped limiting block 708 before the riveting head 704 directly presses the end of the electrode strip, thus fixing the electrode strip and avoiding problems such as misalignment or displacement of the end of the electrode strip during the pressing process, which would result in poor pressing effect.

[0048] The inclined groove 711 and the wedge-shaped limiting block 708 are set with an inclined slope on the bottom side. When fixing the electrode strip, compared with the method of fixing it with two horizontal surfaces, it can provide additional lateral support for the electrode strip. In the process of the second rotating gripper 715 completing the twist and moving out laterally, it can prevent the electrode strip from being pulled to one side and shifting, and further improve the stability of fixing the electrode strip.

[0049] like Figure 1-12 As shown, a limiting top bar 718 is slidably arranged between two side frame blocks 710 in the riveting table 709 along the length of the electrode bar. A top bar support seat 719 is fixedly arranged on the side of the riveting frame 701 facing away from the riveting table 709. A top bar slide seat 720 is slidably arranged on the top bar support seat 719 and fixed to the end of the limiting top bar 718. A top bar screw 721 is rotatably connected to the top bar support seat 719 along the length of the limiting top bar 718 and threadedly connected to the top bar slide seat 720. A top bar drive motor 722 is provided at the end of the top bar support seat 719 and is drivenly connected to the top bar screw 721.

[0050] To ensure that the folded riveting part b is accurately positioned and evenly distributed between layers after processing, the second rotating gripper 715 needs to accurately clamp the end of the electrode strip at a specified position. This places high demands on the positional accuracy of the electrode strip on the riveting table 709. Therefore, after the electrode strip is transferred into the riveting table 709 by the material transfer component VIII, the end of the electrode strip needs to be effectively positioned.

[0051] By setting a limiting top bar 718 that can slide along the length of the electrode strip within the riveting table 709, the position of the limiting top bar 718 can be accurately adjusted, and the end of the limiting top bar 718 abuts against the end of the electrode strip, so as to achieve accurate and stable positioning of the electrode strip, thereby improving processing accuracy and finished product quality. In this embodiment, the end of the limiting top bar 718 preferably has a sunken extension structure, which can support the bottom side of the end of the electrode strip while the end of the limiting top bar 718 abuts against the end of the electrode strip, thus preventing the end of the electrode strip from drooping and affecting the positioning accuracy in the length direction.

[0052] like Figure 1-12As shown, the punching component V includes a punching machine body 503. The processing position of the punching machine body 503 corresponds to the position of the farthest placement seat 817. An adjusting cylinder 502 is provided on the panel II along the length of the placement seat 817 on one side of the punching machine body 503. The rod head of the adjusting cylinder 502 is fixedly connected to an adjusting gripper 501. The position of the adjusting gripper 501 corresponds to the position of the adjacent second flat plate 818.

[0053] Since the finished electrode strip a needs to ensure the accuracy of its punching position to ensure the normal use of subsequent electrode strips, the position of the electrode strip needs to be calibrated before punching. Therefore, by setting the adjusting jaw 501 and the adjusting cylinder 502, before the electrode strip enters the punching machine body 503 for punching, the adjusting jaw 501 is pre-controlled to clamp the end of the electrode strip, and the position of the electrode strip in the length direction is adjusted by the adjusting cylinder 502, so as to realize the function of position calibration and adjustment, improve the punching accuracy and the quality of the final product.

[0054] like Figure 1-12 As shown, the gripper component IV includes a bracket 401, which is disposed around the packaging component III. A top beam 402 is provided on the top of the bracket 401 along the transfer and pushing direction of the electrode strip. A gripper slide 403 is slidably disposed at the bottom of the top beam 402. A gripper screw 404, threadedly connected to the gripper slide 403, is rotatably disposed on the top beam 402. A gripper motor 405, which is drively connected to the gripper screw 404, is fixedly connected to the end of the top beam 402. Gripper lifting seats 406 are vertically slidably connected to both ends of the gripper slide 403. The claw slide 403 is provided with claw telescopic cylinders 407 at both ends. The rod head of the claw telescopic cylinder 407 passes through the claw slide 403 and is fixedly connected to the claw lifting seat 406. The bottom end of the claw lifting seat 406 is provided with a first rotating claw 408 that can rotate and open and close freely. The bottom end of the claw lifting seat 406 is provided with side connecting plates 409 on both sides of the first rotating claw 408. The bottom end of the side connecting plates 409 is fixedly connected with a transfer claw 410. The inner side of the transfer claw 410 is fixedly connected with a limit piece 411.

[0055] By setting up a gripper slide 403 that can move horizontally on the top beam 402, a gripper lifting seat 406 that can move vertically, and a transfer gripper 410, the finished electrode strips a stacked on the transfer stacking table 821 can be transferred to the packaging component III for packaging operations, replacing manual labor and improving the degree of automation. At the same time, by setting 11, the number of electrode strips held by the transfer gripper 410 can be accurately limited, ensuring that the number of finished electrode strips a picked up by the transfer gripper 410 each time is always consistent, thereby ensuring that the number of electrode strips in each group of packs is consistent after packaging.

[0056] Meanwhile, by setting a first rotating gripper 408 that can rotate and open and close freely, it can work with the packaging component Ⅲ to twist the packaging wire containing iron wire, thereby realizing the packaging action by using the packaging wire to completely and firmly wrap a set of finished electrode strips a together.

[0057] like Figure 1-12 As shown, the packaging component III includes a wire feeding plate 301, which is located on the side of panel II near the transfer stacking platform 821. A clamping arm 302 is hinged to the wire feeding plate 301. A set of wire feeding wheels 303 are rotatably connected to the end of the clamping arm 302 and to the wire feeding plate 301 at a position corresponding to the end of the clamping arm 302. A threading plate 304 is fixedly connected to the side of the wire feeding plate 301 near the transfer stacking platform 821. A wire storage wheel 314 for storing packaging wire is provided inside the cabinet I. The wire is conveyed by a set of wire feeding wheels 303 and passes through the threading plate 304. A packaging gripper 307 that can be opened, closed and raised is provided on panel II near the transfer stacking platform 821.

[0058] like Figure 1-12 As shown, a wire feeding motor 312 is fixedly installed on the wire feeding upright plate 301. A wire feeding synchronous belt 313 is connected between the power output end of the wire feeding motor 312 and the corresponding wire feeding wheel 303. A cutting cylinder 306 is fixedly installed on the wire feeding upright plate 301 below the threading plate 304. The rod head of the cutting cylinder 306 is fixedly provided for cutting the wire passing through the threading plate 304. A packing drive cylinder 308 is provided at the bottom of the packing clamp 307 for driving the packing clamp 307 to open and close. A packing lifting cylinder 309 is fixedly installed on the panel II at the position corresponding to the packing drive cylinder 308. The rod head of the packing lifting cylinder 309 is fixed to the bottom of the packing drive cylinder 308. A wire guide plate 310 is fixedly connected on the wire feeding upright plate 301 at the same height as a set of clamping arms 302. Multiple straightening wheels 311 are rotatably connected to each wire guide plate 310 in an alternating manner. The wire passes through the straightening wheels 311.

[0059] The packaging action is completed by setting up a packing gripper 307 to carry and clamp the electrode strip stack transported by gripper component IV, and feeding a fixed length of wire through wire feeding wheel 303. Then, the first rotating gripper 408 clamps the end of the wire and bends the wire containing iron wire in the opposite direction to cover the outside of the stack. The wire is cut by cutter block 305 and then the first rotating gripper 408 twists and fixes the two ends of the discontinuous wire.

[0060] The wire is wound and stored on the wire storage wheel 314. If the wire is taken directly, the internal iron wire is in a bent state. Therefore, the wire needs to be straightened by the straightening wheel 311 first, so that the wire can meet the working requirements and at the same time reduce the difficulty of the first rotating jaw 408 clamping the bent wire.

[0061] The above processing actions are carried out simultaneously and in coordination. Different electrode strips can be loaded, riveted, spot-welded, punched, and packaged at the same time, which effectively saves the time spent on the transfer between multiple processes, greatly improves the processing and production efficiency, and the integration of each processing process on the same equipment makes the connection between them stronger and facilitates the control of the processing and production rhythm.

[0062] In this embodiment, initially, the operator connects the device to the power supply and control system. During operation, the conveyor motor 805 drives the pulley 803 and the conveyor belt 804 to rotate, moving the electrode strip from the far end to one end of the baffle 806 until the end of the electrode strip abuts against the baffle 806 and can no longer move forward. At the same time, the photoelectric sensor installed on the baffle 806 detects the presence of the electrode strip and controls the conveyor motor 805 to stop, thus stopping the conveying of the electrode strip.

[0063] Then, the control system simultaneously controls the first transfer motor 810 and the second transfer motor 813, which enables the crossbeam 814 to rise, fall and move horizontally, and uses the suction cup 816 to pick up the electrode strips on the pulley 803, and then place them on the adjacent second flat plate 818 to release the suction of the electrode strips. Then the feeding action of the pulley 803 and the picking and placing actions are repeated, and each electrode strip is pushed forward on each second flat plate 818 in sequence to realize the transfer action.

[0064] When the electrode strip falls onto the second flat plate 818 corresponding to the riveting component VII, the end of the electrode strip falls onto the riveting table 709 and is located between the two side frame blocks 710. At this time, the second rotating gripper 715 and the bottom support block 713 are located on both sides. The control system controls the top bar drive motor 722 to drive the limiting top bar 718 to move towards the end of the electrode strip until the limiting top bar 718 abuts against the end of the electrode strip and positions the end of the electrode strip. Then, the positioning gripper 819 corresponding to the second flat plate 818 clamps and fixes the main body of the electrode strip.

[0065] Then, the control system controls the first propulsion cylinder 716 to bring the second rotating jaw 715 closer to the end of the electrode strip, while controlling the limiting top bar 718 to retract, and controlling the second rotating jaw 715 to twist the end of the electrode strip so that it wraps around the outside of the tile-shaped jaw 723 to form a spiral structure. Then, the riveting head 704 moves down and moves the wedge-shaped limiting block 708 down with it until the wedge-shaped limiting block 708 presses against the surface of the electrode strip. The electrode strip is embedded in the inclined groove 711 and is completely pressed against the wedge-shaped limiting block 708. At this time, the riveting head 704 does not contact the end of the electrode strip. Then, the second rotating jaw 715 moves laterally to withdraw. During this process, due to the pressing of the wedge-shaped limiting block 708, the electrode strip is prevented from being pulled to one side by the second rotating jaw 715.

[0066] Meanwhile, the bottom support block 713 advances until it is supported at the bottom of the spiral structure. During the advancement of the bottom support block 713, the ramp 714 can prevent the edge of the bottom support block 713 from directly squeezing the spiral structure of the electrode strip, causing it to deform and be damaged. Then the riveting head 704 continues to press down, and the wedge-shaped limiting block 708 remains in position and always presses the electrode strip while the spring 707 is compressed and contracted until the riveting head 704 completely presses the end of the electrode sheet. Under the pressure of the riveting head 704 and the bottom support block 713, the spiral structure at the end of the electrode sheet is flattened, forming a folded riveting part b with stacked layers, thus completing the riveting action.

[0067] Then, the components on the riveting component VII are reset, and the riveted electrode strip is moved to the next station again by the material transfer component VIII. When the electrode strip moves to the corresponding position of the spot welding component VI, the spot welding component VI spots welds the riveted end of the electrode strip to form a weld point c, so as to avoid the problem of loosening and poor conductive contact of the riveted electrode strip end during use.

[0068] After spot welding, the electrode strip continues to be transferred by the material transfer component VIII to the corresponding position of the adjusting jaw 501. The adjusting jaw 501 clamps the end of the electrode strip, and the adjusting cylinder 502 pushes and pulls the electrode strip along its length. This calibrates the punching position of the electrode strip before punching, ensuring the accuracy of the punching position. After calibration, the material transfer component VIII continues to advance the electrode strip to the position of the punching machine body 503. The punching machine body 503 then punches the folded riveting part b of the electrode strip to form a punch. Pressure hole d At this point, the end of the electrode strip completes all processing to form the finished electrode strip a, and then the material transfer component VIII continues to move the finished electrode strip a to the transfer stacking platform 821 and stacks them one by one.

[0069] After a certain number of finished electrode strips a are stacked on the transfer stacking platform 821, the control system automatically controls the gripper slide 403 to reach above the transfer stacking platform 821, controls the gripper lifting seat 406 to descend, and the transfer gripper 410 opens to prepare to clamp the stack of finished electrode strips a. The transfer gripper 410 descends until the limiting piece 411 completely abuts against the stack, then the transfer gripper 410 is restricted from descending further, thereby limiting the number of finished electrode strips a that the transfer gripper 410 can clamp, ensuring that a fixed number of finished electrode strips a can be obtained each time. Then the transfer gripper 410 closes to clamp the stack and transfers the stack to the packing gripper 307.

[0070] Then, the wire feeding motor 312 drives the wire feeding wheel 303 to roll, thereby feeding a fixed length of wire to the packing gripper 307. During the feeding process by the wire feeding wheel 303, the wire is initially released from the wire storage wheel 314 and straightened by the straightening wheel 311 to ensure that the wire is straight for subsequent bundling operations. Then, the first rotating gripper 408 is controlled to work to wrap the wire around the stack. After the cutter block 305 cuts the wire, the first rotating gripper 408 twists and fixes the wire, thereby completing the automatic packing action of the finished electrode strip a stack. Then, the packing stack is moved and placed on the platform IX using the limiting piece 411 to complete all the work.
