Description

Technical Field

[0001] This utility model relates to the field of electrode technology, and more specifically, to a disc-type aluminum-to-nickel electrode. Background Technology

[0002] The positive electrode tab of a soft-pack polymer lithium-ion battery is typically made of pure aluminum. During battery assembly, the positive and negative electrodes need to be connected to other electronic components via soldering. However, the positive electrode tab, made of pure aluminum, cannot be directly soldered. Current processes typically involve soldering a nickel strip to the lead-out end of the positive electrode tab, followed by soldering using the nickel strip. This process is known as the aluminum-to-nickel conversion process for the positive electrode tab of soft-pack polymer lithium-ion batteries.

[0003] However, the technical solution provided by this patent has the following problems:

[0004] Regarding tab positioning, the lack of a precise and effective positioning structure makes tabs prone to displacement during processing. In the welding process, tab displacement leads to weld point deviations, failing to meet the stringent welding precision requirements of batteries and severely impacting their conductivity and stability. During the cutting process, tab displacement makes it difficult to guarantee precise cutting dimensions, resulting in inconsistent tab specifications. This not only increases the defect rate but also wastes raw materials. Furthermore, traditional conveying devices generate excessive friction between the tabs and the conveying components during transport. This not only causes wear on the tab surface, affecting its conductivity, but also easily leads to tab deformation. Deformed tabs cannot be properly fitted to other components in subsequent processing, further reducing processing precision and hindering the improvement of battery yield.

[0005] This invention can accurately position and stabilize the electrode tabs, reduce friction and prevent bending during the conveying process, and control the turntable speed as needed to ensure the stability of the electrode tab processing and improve processing accuracy and efficiency. Utility Model Content

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a disc-type aluminum to nickel electrode tab.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a disc-type aluminum-to-nickel electrode tab, comprising: a fixed frame, a support frame fixedly installed at the bottom upper end of the fixed frame, a turntable rotatably connected to one side of the support frame, a material handling block fixedly installed on the front of the support frame, a connecting block fixedly installed above the support frame, a screw hole three being provided at the connection between the connecting block and the support frame, a bolt one being internally threaded into the screw hole three, an anti-rotation component being fixedly installed at the other end of the bolt one, and a plurality of screw holes four being provided around the screw hole three and the anti-rotation component, and bolts two being internally threaded into the screw holes four provided around the screw hole three.

[0008] A further preferred embodiment: side plates are fixedly installed on both the left and right sides of the upper end of the fixing frame, and a screw hole is opened on the side plate. A baffle is fixedly installed on the front of the upper end of the fixing frame, and a sliding groove is opened at the rear end of the baffle.

[0009] A further preferred embodiment: a motor is fixedly installed on the upper end of the fixing frame, a screw is fixedly installed on the output end of the motor, a movable block is threadedly connected to the screw, a slider is fixedly installed on the front of the movable block, and the slider is slidably connected to the slide groove.

[0010] A further preferred embodiment: connecting plates are fixedly installed at both ends of the movable block, and several screw holes are provided on the connecting plates, the screw holes being matched with the screw holes.

[0011] A further preferred embodiment: a pressure block is fixedly installed at the bottom of the movable block, and an anti-slip pad is provided at the bottom of the pressure block.

[0012] A further preferred embodiment: the turntable is composed of an outer shell and a rotating disk, with the outer shell surrounding the rotating disk and being rotatably connected to it.

[0013] A further preferred embodiment: the material conveying block is rotatably connected to shafts in all directions, and a material conveying plate is fixedly installed at the rear end of the material conveying block, with the rear end of the material conveying plate being arc-shaped.

[0014] Beneficial effects:

[0015] 1. The device is equipped with screw hole one, slide groove, moving block, screw hole two, and pressure block. Screw hole one on the side plate matches screw hole two on the connecting plates at both ends of the moving block. Operators can connect the two with pins or bolts according to actual needs, effectively preventing the moving block from shifting due to external force during processing, thus ensuring the stability of the electrode tab limit. The motor drives the screw to rotate, causing the moving block to move smoothly along the screw axis in the slide groove. This precise movement control allows the pressure block to descend accurately. The anti-slip pad at the bottom of the pressure block can firmly press the electrode tab into place and limit it after contacting the nickel strip and aluminum strip, preventing it from shifting during processing. Operators can also adjust the position of the pressure block in real time according to the electrode tab position deviation by fine-tuning the motor rotation direction and number of rotations to achieve precise limit.

[0016] 2. By incorporating a rotating shaft and a feed plate, the feed block is internally connected to rotating shafts in all directions. During electrode conveying, these shafts can rotate flexibly, providing guidance and support for the electrodes, reducing frictional resistance between the electrodes and the feed block, making electrode conveying smoother, and reducing the probability of electrode damage during conveying. The feed plate is fixed at the rear end of the feed block, and its rear end is arc-shaped, which can guide the nickel strip and aluminum strip smoothly into the subsequent processing position, avoiding bending or deviation of the electrodes, and ensuring the stability and accuracy of electrode conveying. The coordinated operation of the rotating shaft and the feed plate optimizes the electrode conveying process, which helps to improve the processing quality and production efficiency of the electrodes.

[0017] 3. By incorporating an anti-rotation component, its advantages become apparent when the rotation of the turntable needs to be controlled. By loosening bolt two, bolt one can be pushed, causing the anti-rotation component to adhere to the turntable surface. Continuously pushing the anti-rotation component inward significantly increases the friction between it and the turntable. Then, bolt two is tightened, and the anti-rotation component is positioned using the engagement of screw hole four and bolt two, maintaining continuous contact with the turntable. This reduces the turntable's rotation speed until it stops smoothly. During the electrode tab processing, the turntable's start and stop can be precisely controlled as needed, preventing excessive electrode tab feeding or positional deviation caused by continuous turntable rotation. This provides a stable working state for electrode tab positioning and subsequent processing, greatly improving the controllability and accuracy of electrode tab processing operations.

[0018] 4. In summary, this disc-type aluminum-to-nickel electrode tab, through its structure including screw hole one, slide groove, moving block, screw hole two, pressure block, anti-rotation component, rotating shaft, and feed plate, effectively stabilizes the moving block by connecting screw hole one on the side plate and screw hole two on the moving block connecting plate with pins or bolts, ensuring stable electrode tab positioning. The motor drives the screw, which, in conjunction with the slide groove, allows the moving block to move precisely. The pressure block and anti-slip pad reliably limit the electrode tab's position. Operators can also fine-tune the motor to precisely position the pressure block. The anti-rotation component can control the turntable's start and stop as needed to prevent electrode tab conveying deviation. The rotating shaft of the feed block reduces electrode tab conveying friction, and the arc-shaped rear end of the feed plate guides the electrode tab smoothly into the processing position, avoiding bending and deviation. This provides stable and precise operating conditions for electrode tab processing, contributing to efficient electrode tab production. Attached Figure Description

[0024] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0025] Please see Figure 1-4 In this embodiment of the utility model, a disc-type aluminum-to-nickel electrode lug includes: a fixed frame 1, a support frame 2 fixedly installed at the upper bottom of the fixed frame 1, a turntable 3 rotatably connected to one side of the support frame 2, a material handling block 4 fixedly installed on the front of the support frame 2, a connecting block 201 fixedly installed above the support frame 2, a screw hole 202 is provided at the connection between the connecting block 201 and the support frame 2, a bolt 203 is internally threaded into the screw hole 202, an anti-rotation component 204 is fixedly installed at the other end of the bolt 203, a plurality of screw holes 205 are provided around the screw hole 202 and the anti-rotation component 204, and bolts 206 are internally threaded into the screw holes 205. The turntable 3 is composed of a shell and a rotating disc. The shell wraps around the rotating disc and is rotatably connected to the rotating disc. First, the rotating disc of the turntable 3 is inserted into the shell, so that the shell wraps around the rotating disc and achieves rotatable connection, thus completing the assembly of the turntable 3. The assembled turntable 3 is rotatably connected to one side of the support frame 2. The material handling block 4 is fixedly installed on the front of the support frame 2. The connecting block 201 is installed above the support frame 2. The bolt 203 is screwed into the screw hole 202 at the connection between the connecting block 201 and the support frame 2. The anti-rotation part 204 is installed on the other end of the bolt 203. The bolt 206 is screwed into the screw hole 205 on the periphery of the screw hole 202. Then, the nickel strip and aluminum strip are wrapped around the turntable 3, so that the material can be discharged as the turntable 3 rotates. When it is necessary to stop the rotation of the turntable 3, the bolt 206 can be loosened first. Then the bolt 203 is moved towards the turntable 3 so that the anti-rotation part 204 is in contact with the surface of the turntable 3 and continuously pushed inward to increase the friction between the two. Then the bolt 206 is tightened. The anti-rotation part 204 is positioned by the cooperation of the screw hole 205 and the bolt 206, so that the anti-rotation part 204 is in continuous contact with the turntable 3, thereby reducing the rotation speed of the turntable 3.

[0026] In this embodiment of the present invention, a baffle 103 is fixedly installed on the front of the upper end of the fixing frame 1, and a slide groove 104 is provided at the rear end of the baffle 103. A motor 105 is fixedly installed on the upper end of the fixing frame 1, and a screw 106 is fixedly installed on the output end of the motor 105. A moving block 107 is threadedly connected to the screw 106, and a slider 108 is fixedly installed on the front of the moving block 107. The slider 108 is slidably connected to the slide groove 104. A pressure block 1101 is fixedly installed at the bottom of the moving block 107, and an anti-slip pad is provided at the bottom of the pressure block 1101. When it is necessary to press and limit the nickel strip and aluminum strip, the motor 105 is driven first. The motor 105 drives the screw 106 to rotate. Since the moving block 107 is threadedly connected to the screw 106, and the slider 108 slides in the slide groove 104, the rotation of the moving block 107 is restricted. Therefore, the moving block 107 will move downward along the axial direction of the screw 106. As the moving block 107 moves downward, its bottom is fixed. The pressure block 1101 also descends. When the anti-slip pad at the bottom of the pressure block 1101 contacts the nickel strip and aluminum strip, the motor 105 continues to drive, causing the pressure block 1101 to apply pressure to the nickel strip and aluminum strip. The anti-slip pad increases friction, firmly pressing the nickel strip and aluminum strip into position to prevent displacement during processing. During the limiting process, the operator must constantly observe the position and pressure of the nickel strip and aluminum strip to ensure good limiting effect. If the position of the nickel strip and aluminum strip is found to be deviated, the position of the pressure block 1101 can be adjusted appropriately by fine-tuning the rotation direction and number of turns of the motor 105 to achieve precise limiting. After the nickel strip and aluminum strip are pressed and limited, subsequent electrode processing procedures such as welding and cutting can be carried out. After processing is completed, the motor 105 is reversed, causing the screw 106 to reverse, and the moving block 107 drives the pressure block 1101 to move upward, releasing the limiting of the nickel strip and aluminum strip, so as to carry out the next batch of electrode processing operations.

[0027] In this embodiment of the utility model, side plates 101 are fixedly installed on both the left and right sides of the upper end of the fixed frame 1. The side plates 101 are provided with screw holes 102. The left and right ends of the moving block 107 are fixedly installed with connecting plates 109. The connecting plates 109 are provided with a plurality of screw holes 110. The screw holes 110 are matched with the screw holes 102. During the limiting process, the operator can, according to actual needs, align the screw holes 110 on the connecting plate 109 with the screw holes 102 on the side plates 101, and use pins or bolts to connect and fix them, thereby further stabilizing the position of the moving block 107 and preventing the position of the moving block from shifting due to external force during the processing, which would affect the limit effect of the tab.

[0028] In this embodiment of the utility model, the feed block 4 is rotatably connected to the upper, lower, left, and right sides of the feed block 4. The feed plate 402 is fixedly installed at the rear end of the feed block 4. The rear end of the feed plate 402 is arc-shaped. The feed blocks 401 are installed at corresponding positions in the upper, lower, left, and right sides of the feed block 4 to ensure smooth rotational connection between the feed blocks and the feed blocks without jamming. The rotatably connected feed shafts 401 can provide more flexible guidance and support for the tabs during the subsequent tab conveying process, reducing frictional resistance. The feed plate 402 is fixedly installed at the rear end of the feed block 4, so that the arc-shaped side of the rear end of the feed plate 402 faces the working area. The arc-shaped design of the rear end of the feed plate 402 helps to guide the nickel strip and aluminum strip to enter the subsequent processing position more smoothly, avoiding bending or deviation of the tabs during the conveying process.

[0029] Working principle: The support frame 2 is fixedly installed on the upper bottom of the fixed frame 1, ensuring a stable connection without shaking. A baffle 103 is fixedly installed on the front upper end of the fixed frame 1, ensuring accurate installation and not affecting the operation of subsequent components. Side plates 101 are fixedly installed on the left and right sides of the upper end of the fixed frame 1, ensuring the side plates are firmly installed and horizontally symmetrical. The rotating disk of the turntable 3 is installed inside the outer casing, ensuring the casing tightly encloses the rotating disk and the two can rotate flexibly, completing the assembly of the turntable 3. The assembled turntable 3 is then rotatably connected to one side of the support frame 2. Rotary shafts 401 are installed in corresponding positions on the top, bottom, left, and right sides inside the feed block 4, ensuring smooth rotational connection between the shafts and the feed block without jamming. The rotating shafts 401 will be used in the subsequent electrode conveying process... The tabs provide flexible guidance and support, reducing frictional resistance. The feed plate 402 is fixedly installed at the rear end of the feed block 4, ensuring that the curved side of the rear end of the feed plate 402 faces the working area. The curved design of the rear end of the feed plate 402 helps guide the nickel and aluminum strips smoothly into the subsequent processing position, preventing bending or offset during tab conveying. After installation, the motor 105 is fixedly installed on the upper end of the mounting bracket 1, ensuring a secure motor installation. The screw 106 is installed on the output end of the motor 105 and fixed, ensuring a tight connection and stable power transmission. The moving block 107 is threaded onto the screw 106. A slider 108 is fixedly installed on the front of the moving block 107, aligning the slider 108 with the groove 104 at the rear end of the baffle 103 to achieve sliding... For the moving block 107, connect plates 109 are fixedly installed at both ends, ensuring the connecting plates are vertical and tightly connected to the moving block. A pressure block 1101 is fixedly installed at the bottom of the moving block 107, and an anti-slip pad is installed at the bottom of the pressure block 1101, ensuring it is firmly adhered and effectively prevents slippage. Connecting block 201 is installed above support frame 2. Bolt 203 is screwed into screw hole 202 at the connection between connecting block 201 and support frame 2. An anti-rotation element 204 is installed at the other end of bolt 203. Bolt 206 is screwed into screw hole 205, which is located around screw hole 202. At this point, the anti-rotation element 204 does not yet brake the turntable 3. The nickel and aluminum strips are then wrapped around the turntable 3, ensuring the electrode tabs are correctly installed. The material can be smoothly discharged as the turntable 3 rotates. When it is necessary to stop the rotation of the turntable 3, first loosen bolt 206, then move bolt 203 towards the turntable 3, so that the anti-rotation part 204 is in contact with the surface of the turntable 3 and continuously pushed inward to increase the friction between the two. Then tighten bolt 206. The anti-rotation part 204 is positioned by the cooperation of screw hole 205 and bolt 206, so that the anti-rotation part 204 is in continuous contact with the turntable 3, reducing the rotation speed of the turntable 3 until it stops. When it is necessary to press and limit the nickel strip and aluminum strip, drive motor 105. Motor 105 drives screw 106 to rotate. Since the moving block 107 is threadedly connected to screw 106 and the slider 108 slides in the groove 104, the rotation of the moving block 107 is restricted.Therefore, the moving block 107 will move downwards along the axial direction of the screw 106. As the moving block 107 moves downwards, the pressure block 1101 fixed at its bottom also descends. When the anti-slip pad at the bottom of the pressure block 1101 contacts the nickel strip and aluminum strip, the drive motor 105 continues to apply pressure to the nickel strip and aluminum strip. The anti-slip pad increases friction, firmly pressing the nickel strip and aluminum strip to limit their movement and prevent displacement during processing. During the limiting process, the operator can, according to actual needs, align the screw hole 110 on the connecting plate 109 with the screw hole 102 on the side plate 101 and use pins or bolts to connect and fix them, further stabilizing the position of the moving block 107 and preventing the moving block from shifting due to external force during processing, which would affect the electrode tab limiting effect. The operator needs to constantly observe the position and pressure of the nickel strip and aluminum strip. To ensure proper positioning, if any deviation in the position of the nickel and aluminum strips is found, the position of the pressure block 1101 can be adjusted appropriately by fine-tuning the rotation direction and number of turns of the motor 105 to achieve precise positioning. After the nickel and aluminum strips are pressed and positioned, subsequent electrode processing steps such as welding and cutting can be performed. After processing, the reverse drive motor 105 is used to reverse the screw 106, and the moving block 107 moves the pressure block 1101 upward, releasing the positioning of the nickel and aluminum strips. If the connecting plate and side plate were previously fixed with pins or bolts, the pins or bolts must be removed first. If the turntable 3 needs to be rotated again to deliver the electrode tabs, loosen bolt 206, move bolt 203 away from the turntable 3 to separate the anti-rotation part 204 from the turntable 3, and then tighten bolt 206. The turntable 3 can then be rotated again for the next batch of electrode tab processing.
