Description
Technical Field
[0001] This invention relates to the field of textile equipment technology, specifically to an automatic arrangement device for nickel-plated tabs of lithium batteries. Background Technology
[0002] In the production and assembly of lithium batteries, nickel-plated tabs are the core components connecting the cell to the external circuitry. Their regularity directly determines the welding yield, structural stability, and safety of the lithium battery, making them a key quality control point in cell manufacturing and module PACK assembly. After cutting and grinding, nickel-plated tabs are prone to variations in length, orientation, and stacking / adhesion. If these tabs proceed directly to subsequent welding, winding / stacking processes, it can lead to poor soldering, detachment, sparking, or even damage to the separator, causing internal short circuits within the cell, significantly reducing the yield and reliability of the finished lithium battery.
[0003] Currently, the arrangement of nickel-plated tabs in lithium battery production is still largely done manually. This involves long working hours, high labor intensity, and low arrangement efficiency. Furthermore, manual arrangement cannot guarantee the uniformity of tab orientation, spacing, and flatness, making it difficult to adapt to the mass production requirements of automated production lines. It also cannot be precisely integrated with subsequent standardized equipment such as ultrasonic welding, laser nickel transfer, and cell winding / stacking, becoming a key bottleneck restricting the improvement of lithium battery production efficiency and product quality. Existing patents do not yet contain specific technologies related to the automated arrangement of nickel-plated tabs. If the issues of speed and accuracy in the automated arrangement of nickel-plated tabs cannot be resolved in a timely manner, it will directly affect the process flow and yield control of the entire cell manufacturing process, greatly restricting the overall production rhythm of lithium batteries. Summary of the Invention
[0004] To address the technical problems existing in the background art, this invention proposes an automatic arrangement device for nickel-plated electrode tabs of lithium batteries. It can standardize and arrange the cut and polished nickel-plated electrode tabs in a regular manner, ensuring that the electrode tabs have a uniform orientation, are evenly distributed, and are flat and well-fitted. The arrangement process is fully automated and can be seamlessly connected with subsequent welding, winding / stacking processes in lithium battery automated production lines, greatly improving the efficiency and accuracy of electrode tab arrangement. The device has a reasonable structure and is suitable for widespread application.
[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: An automatic arrangement device for nickel-plated electrode tabs of lithium batteries includes an electrode tab conveying unit and an arrangement unit. The electrode tab conveying unit is used to convey nickel-plated electrode tabs to the arrangement unit in a fixed posture. The arrangement unit is used to arrange the nickel-plated electrode tabs. The arrangement unit includes a worktable, a power mechanism, an adjustment mechanism, and a storage mechanism. The power mechanism includes a slide rail fixed to one side of the worktable and rotating blades that rotate circumferentially along a vertical cut groove. The adjustment mechanism is located on both sides of the worktable and includes inclined plates with gradually changing spacing. The storage mechanism includes an electrode tab receiving plate and a transmission hook. The electrode tab receiving plate is detachably fixed to the worktable by a threaded rod. A first limiting block is provided above the plate. A docking slide rail is provided on the side of the plate near the slide rail. The transmission hook is connected to the adjustment mechanism by a connecting rod. A transmission rod with a hook claw is provided below the beam plate.
[0006] By adopting the above technical solution, after the nickel-plated electrode tabs enter the slide through the conveying unit, they slide down under the push of the rotating blades, are aligned to a uniform orientation by the inclined plate, and then move to the plate along the docking slide. The rectangular notch in the width direction of the electrode tabs fits into the limiting block to achieve lateral positioning. Finally, the transmission hook transfers the oriented electrode tabs. The entire process is automated to complete the double precision oriented alignment, ensuring the consistency and stability of the electrode tab arrangement.
[0007] Preferably, the electrode conveying unit is a conveyor belt, which is located in the upward inclined direction of the slide. The slide has side guards on both sides, and the conveyor belt is used to smoothly convey the polished nickel-plated electrode into the slide.
[0008] By adopting the above technical solution, the conveying of nickel-plated tabs is smoother, the side guards can prevent the tabs from tipping over and falling off, and ensure that the tabs enter the slide in a specific posture, avoiding stacking and tilting during the feeding process, thus laying the foundation for subsequent straightening processes.
[0009] Preferably, the power mechanism includes a rotary motor, the output shaft of which is fixedly connected to the rotary blade, and the worktable and slide are provided with several vertical cut grooves. The rotary blade is in contact with the nickel-plated tab body and pushes it down.
[0010] By adopting the above technical solution, the rotating motor drives the rotating blade to rotate stably, and the blade contacts the tab surface to achieve smooth conveying, avoiding the tab jamming or offset. The conveying speed can be adjusted by the motor speed to adapt to different production line rhythms. The vertical cut groove provides rotation space for the rotating blade to ensure accurate and reliable transmission.
[0011] Preferably, the spacing between the inclined plates gradually decreases inward and is connected to the discharge end of the slide. When the rotating blade drives the nickel-plated electrode tabs to slide down, the two sides of the electrode tabs abut against the inclined plates to calibrate the orientation.
[0012] By adopting the above technical solution, the inclined plate forms a gradually changing guide channel, and the position of the inclined plate can be fixed by adjusting bolts to accommodate different width tabs.
[0013] Preferably, the tab receiving plate includes a plate body, a threaded rod, and a nut. The plate body is fixed to the vertical cut groove of the worktable by the threaded rod and the nut and can be adjusted back and forth along the groove. A first limiting block is provided above the plate body, and a second limiting block is provided on the docking slide. The first limiting block and the second limiting block are aligned to form a guide channel.
[0014] By adopting the above technical solution, the docking slide achieves a smooth transition of the electrode ear from the slide to the plate. The plate can be adjusted back and forth to accommodate electrode ears of different lengths. The first and second limiting blocks fit into the rectangular notch of the electrode ear to form a precise lateral positioning. The width of the guide channel is slightly larger than the width of the electrode ear to ensure that the electrode ear enters smoothly without deviation.
[0015] Preferably, the nickel-plated tab is a flat, elongated structure, made of pure copper substrate plated with nickel, without any additional complex structure, and is in the shape of a rectangular sheet, with a rectangular notch on one side of the nickel-plated tab.
[0016] By adopting the above technical solution, the electrode structure is extremely simple and the processing cost is low. The two ends of the electrode can be designed with rounded corners to avoid scratching the equipment or operators. The rectangular notch is set in a non-core functional area, which does not affect the electrode's conductivity and welding performance, and can be precisely matched with the limiting block to achieve lateral positioning.
[0017] Preferably, the transmission hook body includes a beam plate, a transmission rod, a hook claw, and a telescopic motor. Adjusting nuts are provided on both sides of the connecting rod. A T-slot is provided below the beam plate. The transmission rod is placed in the T-slot. The hook claw and the transmission rod are rotatably connected by a pin. A torsion spring is provided at the pin.
[0018] By adopting the above technical solution, the telescopic motor drives the transmission rod to move back and forth along the T-slot. The height of the beam plate can be adjusted by adjusting the nut to adapt to pole ears of different thicknesses. The hook adopts a gravity and spring reset self-opening and closing structure, which does not require additional driving components, and realizes the pole ears to be hooked and transferred without damage. Preferably, the arrangement unit further includes a double rotating blade structure, wherein the rotating blade includes a first rotating blade and a second rotating blade, which are driven by different motors respectively. The first rotating blade pushes the electrode tab to the bottom of the slide, and the second rotating blade pushes the electrode tab at the bottom of the slide towards the plate. The first rotating blade is in contact with the nickel-plated electrode tab body and pushes it down along the inclined surface. The second rotating blade abuts against the side of the electrode tab and applies a lateral thrust.
[0019] By adopting the above technical solution, the dual rotating motors independently drive the blades to rotate. The first rotating blade is responsible for smooth conveying, and the second rotating blade is responsible for lateral flipping. The conveying speed and flipping force can be independently adjusted by the motor speed to adapt to different production line rhythms. The vertical cut groove provides rotation space for the rotating blades, ensuring that the transmission process is accurate and reliable.
[0020] Preferably, the beam plate has an opening, and the automatic arrangement device also includes an auxiliary mechanism. The auxiliary mechanism includes a roller, a rotating rod, a belt, and magnetic plates. The roller is connected to the belt drive, the rotating rod passes through the roller and is rotatably connected to the adjustment mechanism, and the magnetic plates are spaced apart on the belt. The auxiliary mechanism is used to magnetically attract the electrode tabs transferred by the hook claw, which solves the technical problem that upright electrode tabs are easy to tip over during transfer.
[0021] The beneficial technical effects of this invention are as follows: (1) This invention achieves ultra-high precision regularity with lateral offset of ≤0.03mm and longitudinal spacing error of ≤0.2mm by calibrating with tilting plate and limiting docking, which completely solves the welding problems caused by skewed electrode arrangement and uneven spacing, and provides standardized electrode components for subsequent lithium battery assembly; (2) The core components of the device can be flexibly adjusted. The front and rear positions of the plate, the height of the beam plate, the spacing of the limit blocks and the spacing of the inclined plates can all be adapted to different specifications of pole ears. It has strong versatility and does not require separate equipment for different specifications of pole ears. (3) The fully automated processing of nickel-plated tab arrangement is realized. From feeding, calibration, regularization to transfer, no human intervention is required. The arrangement efficiency can reach 1200 pieces / hour, which is more than 3 times higher than manual labor. It effectively reduces labor costs and labor intensity, and solves the industry pain point that traditional manual arrangement cannot be adapted to automated production lines. (4) The structure is reliable. The hook adopts an autonomous opening and closing structure. The limit block can be made of rubber to avoid damaging the nickel plating layer on the electrode surface, ensuring the appearance quality and conductivity of the electrode. It can be accurately connected with subsequent automated equipment such as ultrasonic welding, laser nickel conversion, and cell winding, which greatly improves the overall production yield and process efficiency of lithium batteries.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0033] like Figure 1 , Figure 2As shown, an automatic arrangement device for nickel-plated electrode tabs of lithium batteries includes an electrode tab conveying unit and an arrangement unit. The electrode tab conveying unit is used to convey the nickel-plated electrode tabs to the arrangement unit in a fixed posture. The arrangement unit is used to arrange the nickel-plated electrode tabs. The arrangement unit includes a workbench 1, a power mechanism 2, an adjustment mechanism 4, and a storage mechanism 3. The power mechanism 2 includes a slide rail 21 fixed to one side of the workbench 1 and a rotating blade 22 that rotates circumferentially along a vertical cut groove 11. The adjustment mechanism 4 is located on both sides of the workbench 1 and includes inclined plates 41 with gradually changing spacing. The storage mechanism 3 includes an electrode tab receiving plate 31 and a transmission hook 32. The electrode tab receiving plate 31 is detachably fixed to the workbench 1 by a threaded rod. A first limiting block 312 is provided above the plate 311. A docking slide rail 5 is provided on the side of the plate 311 near the slide rail 21. The transmission hook 32 is connected to the adjustment mechanism 4 by a connecting rod 325. A transmission rod 322 with a hook claw 323 is provided below the beam plate 321.
[0034] Before entering the electrode conveying unit, the electrodes undergo preliminary screening by a visual recognition and pneumatic sorting and orientation system. The pneumatic sorting unit consists of several miniature pneumatic push rods that are linked with the vision system signals to separate the electrodes that are arranged in the opposite direction and reload them.
[0035] After the nickel-plated tabs enter the slide 21 via the conveying unit, they slide down under the push of the rotating blades 22. After being aligned to a uniform orientation by the inclined plate 41, they move along the docking slide 5 to the plate 311, where they collide with the plate 311 to form a longitudinal reference. The rectangular notch 71 in the tab width direction engages with the limiting block to achieve lateral positioning. Finally, the transmission hook 32 transfers the aligned tabs in an oriented manner. The entire process is automated to complete the double precision alignment, ensuring the consistency and stability of the tab arrangement and laying the foundation for subsequent processes such as lithium battery welding, winding / stacking.
[0036] The electrode conveying unit is a conveyor belt, which is located in the upward inclined direction of the slide 21. The slide 21 has side guards on both sides. The conveyor belt is used to smoothly transport the polished nickel-plated electrode into the slide 21.
[0037] The conveying of nickel-plated tabs is smoother, and the side guards can prevent the tabs from tipping over and falling off, ensuring that the tabs enter the slide 21 in a specific posture, avoiding stacking and tilting during the feeding process. The conveyor belt speed and the rotation speed of the rotating blades 22 are coordinated to ensure uniform feeding of the tabs and adapt to the subsequent regular rhythm.
[0038] The power mechanism 2 includes a rotary motor 23, the output shaft of which is fixedly connected to the rotary blade 22. The worktable 1 and the slide 21 are provided with several vertical cut grooves 11. The rotary blade 22 fits against the nickel-plated tab 7 body and pushes it down.
[0039] The rotating motor 23 drives the rotating blade 22 to rotate stably. The blade contacts the tab surface to achieve smooth conveying and avoid the tab from jamming or shifting. The conveying speed can be adjusted by the motor speed to adapt to different production line rhythms. The vertical cut groove 11 provides rotation space for the rotating blade 22 to ensure accurate and reliable transmission. The rotating blade 22 is made of nylon material to avoid damaging the nickel plating layer of the tab.
[0040] The spacing between the inclined plates 41 gradually decreases inward and connects with the discharge end of the slide 21. When the rotating blade 22 drives the nickel-plated tabs 7 to slide down, the two sides of the tabs abut against the inclined plates 41 to calibrate the orientation.
[0041] The tab receiving plate 31 includes a plate body 311, a threaded rod, and a nut. The plate body 311 is fixed to the vertical cut groove 11 of the workbench 1 by the threaded rod and the nut and can be adjusted back and forth along the groove. A first limiting block 312 is provided above the plate body 311, and a second limiting block 51 is provided on the docking slide 5. The first limiting block 312 and the second limiting block 51 are aligned to form a guide channel, and their inner sides correspond to the rectangular notch 71 of the tab. The second limiting block 51 and the plate body 311 can be detached to adapt to different styles of tabs.
[0042] The nickel-plated tab 7 has a minimalist, flat, elongated structure. It is made of pure copper substrate with nickel plating on the surface. It has no additional complex structure and is rectangular in shape with rounded corners at both ends. A rectangular notch 71 is provided on one edge of the tab in the width direction.
[0043] The transmission hook body 32 includes a beam plate 321, a transmission rod 322, a hook claw 323, and a telescopic motor 324. Adjusting nuts are provided on both sides of the connecting rod 325. A T-slot 326 is provided below the beam plate 321. The transmission rod 322 is placed in the T-slot 326. The hook claw 323 is rotatably connected to the transmission rod 322 through a pin. A torsion spring is provided at the pin.
[0044] The beam plate 321 is made of stainless steel, and the connecting rod 325 is an M10 threaded rod. The height of the beam plate 321 can be adjusted by adjusting the nut. The bottom of the transmission rod 322 is hollow, and the hook 323 is made of stainless steel. When the device is stationary, it is in the open state. When it moves towards the inclined slide 21, it retracts against the pole ear. When it moves away from the inclined slide 21, it resets and hooks the pole ear, realizing the longitudinal attitude pole ear transfer without damage. The telescopic motor 324 has a stroke of 500mm and a thrust of 50N, driving the transmission rod 322 to move smoothly along the T-slot 326.
[0045] During operation, the conveyor belt smoothly transports the electrode tabs to the inclined slide 21. The first rotating blade 221 pushes the nickel-plated electrode tabs 7 down the 20° inclined surface and calibrates them to their initial posture by the inclined plate 41. Then, the second rotating blade 222 applies a lateral thrust at a 30° angle, which, together with the component of gravity, forces the nickel-plated electrode tabs 7 to rotate 90° and enter the docking slide 5. The rectangular notch 71 engages with the limiting block to achieve lateral positioning. When the electrode tabs reach the preset number, the telescopic motor 324 drives the transmission rod 322 to move, and the hook 323 picks up the electrode tabs and transfers them to the end of the plate 311. Finally, the automated robot grabs the neatly arranged electrode tabs from the end and seamlessly transfers them to the subsequent welding process.
[0046] Specifically, an automatic arrangement process for nickel-plated tabs in lithium batteries includes the following steps: A. The conveyor belt transports the long strip-shaped nickel-plated electrode tabs 7 to the slide 21. The rotating blades 22 push the electrode tabs downward along the slide 21 and calibrate them to a uniform orientation via the inclined plate 41. B. The electrode ear moves along the docking slide 5 to above the plate 311. The gravity of the inclined slide 21 and the lateral thrust of the second rotating blade jointly apply a combined force, forcing the electrode ear to rotate 90° along the side wall of the slide 21 and actively form a longitudinal posture. The rectangular notch 71 in the width direction of the electrode ear is engaged with the first limiting block 312 and the second limiting block 51 to achieve double regularization. The electrode ear continues to be pushed to maintain a uniform longitudinal arrangement. C. The telescopic motor 324 drives the transmission rod 322 to move, and the hook 323 hooks the aligned pole ear, causing it to move away from the slide 21. D. Organize the neatly arranged tabs at the end of plate 311 and proceed to the next arrangement cycle.
[0047] In another embodiment of the present invention, the beam plate 321 is provided with an opening 6, and the front and rear ends of the opening 6 are provided with inclined slopes to facilitate the entry of the magnetic absorbing piece 64. The automatic arrangement device also includes an auxiliary mechanism, which includes a roller 61, a rotating rod 62, a belt 63 and magnetic absorbing pieces 64. The roller 61 is connected to the belt 63 for transmission, and the rotating rod 62 passes through the roller 61 and is rotatably connected to the adjustment mechanism 4. The magnetic absorbing pieces 64 are distributed at intervals on the belt. The auxiliary mechanism is used to magnetically attract the pole tabs transferred by the hook 323. The hook 323 is the power source for the auxiliary mechanism. Driven by the telescopic motor 324, the hook 323 moves the electrode tabs towards the end of the plate 311. After each electrode tab is delivered by the hook 323, the magnetic piece inside the buckle 6 of the beam plate 321 moves backward one position, and the upright electrode tab forms a magnetic attraction for auxiliary positioning. The magnetic piece 64 automatically retracts with the linkage structure to maintain magnetic attraction and prevent the electrode tab from tipping over. After being moved into place, the hook 323 releases the electrode tab, and the telescopic motor 324 drives the hook 323 forward to continue hooking the nickel-plated electrode tabs. This process is repeated until the automated robotic arm picks them up for subsequent welding processes. For specific connection relationships, please refer to the appendix. Figure 9.
