Description

Technical Field

[0001] This utility model relates to an electroplating winding device for bipolar current collectors, specifically an electroplating winding device for bipolar current collectors, belonging to the technical field of winding devices. Background Technology

[0002] The electroplating winding device for bipolar current collectors is a key piece of equipment designed specifically for the continuous and automated winding of bipolar current collector materials in the electroplating process. It can precisely adapt to the winding requirements of bipolar current collectors during the electroplating process. Through a precise tension adjustment system, the device ensures that the material is subjected to uniform force during the winding process, avoiding problems such as deformation and wrinkles caused by stretching or loosening. At the same time, in conjunction with the speed synchronization mechanism with the outlet end of the electroplating tank, it ensures the consistency of the coating thickness.

[0003] The prior art patent application number is 202123332086.2, entitled "An Adjustable Winding Device for PI Film Processing," which includes a base. A first upright plate is fixedly installed on the base, and a second upright plate is movably arranged on the base. A guide roller and a tension roller are rotatably installed between the first and second upright plates, respectively. A positioning seat is fixedly installed on one side of the second upright plate, and a positioning block is fixedly installed inside the positioning seat by bolts. One end of the guide roller is rotatably installed on the positioning block by a bearing. A second through hole is opened on both the first and second upright plates, and a round rod is fixedly installed inside the second through hole on the first upright plate. This invention allows for adjustment of the height of the tension roller, thus facilitating adjustment of the tension of the PI film. It is applicable to PI film winding in various environments, has a simple disassembly and assembly structure, and is convenient for disassembling, replacing, and maintaining the guide roller.

[0004] However, after the height of the tension roller is adjusted, the threaded rod is prone to self-rotation under the influence of factors such as vibration generated during equipment operation, slight external impact, or long-term stress. This unexpected self-rotation directly causes the set height of the tension roller to deviate, thereby disrupting the originally calibrated tension balance. This may not only affect the transmission accuracy of related materials, but also aggravate the wear of equipment parts, and even create hidden quality and safety risks in the production process. Therefore, a new technical solution needs to be designed to address this issue. Summary of the Invention

[0005] The purpose of this utility model is to provide a bipolar current collector electroplating winding device to solve the above-mentioned problems, so as to solve a significant defect in the existing tension roller height adjustment mechanism: its core component threaded rod is not equipped with an effective locking mechanism. After the operator completes the height adjustment of the tension roller, the threaded rod is very prone to self-rotation under the influence of factors such as vibration generated by the operation of the equipment, slight external collisions, or long-term stress.

[0006] This utility model is achieved through the following technical solution: an electroplating winding device for bipolar current collectors.

[0007] The device includes a mounting frame, with a take-up roller rotatably connected to its inner side. A motor is fixedly connected to one side of the mounting frame, with one end of the motor's power output shaft passing through the mounting frame and fixedly connected to the take-up roller. An anti-slip sleeve is fitted onto the outer side of the take-up roller, and anti-slip grooves are evenly distributed on the outer side of the anti-slip sleeve. Two rotating rods are rotatably connected to the top of the mounting frame, with locking grooves arranged sequentially from top to bottom on the outer side of each rotating rod. The mounting frame provides a stable support foundation for the entire device. Driven by the motor, the take-up roller can automatically rewind materials, saving labor costs and improving rewinding efficiency. The locking grooves on the rotating rods provide locking stability for subsequent locking and fixing, and the anti-slip sleeve and anti-slip grooves effectively improve the stability of the rewinding process.

[0008] Preferably, the bottom end of the rotating rod passes through the mounting frame and extends to the inner side of the mounting frame, and a threaded rod is fixedly connected to the bottom end of the rotating rod. A fixed frame is screwed to the outer side of the threaded rod. The rotating rod is connected to the threaded rod. By rotating the rotating rod, the threaded rod can be driven to rotate. By utilizing the screwed connection between the threaded rod and the fixed frame, the rotational motion can be converted into the vertical linear motion of the fixed frame, thereby achieving precise adjustment of the height of the fixed frame and meeting the requirements for material handling height under different working conditions.

[0009] Preferably, four mounting chambers are fixedly connected to the inner side of the fixing frame, and two friction rods are fixedly connected to the inner side of each mounting chamber. A compression spring is sleeved on the outer side of each friction rod, and a first repulsive magnet is fixedly connected to the top of the inner cavity of each mounting chamber. The mounting chamber provides mounting space for the internal friction rods, compression springs, and first repulsive magnets, and plays a role in protection and positioning. The friction rods provide guidance for the sliding of the moving plate, ensuring the stability of the moving plate's movement. The compression springs can apply downward pressure to the moving plate, and the first and second repulsive magnets can generate a repulsive force together to adjust the position of the moving plate, so that the relevant components can better adapt to the working requirements.

[0010] Preferably, a movable plate is slidably connected to the outer side of the friction rod, and two friction sleeves are fixedly connected to the bottom of the movable plate. The friction sleeves are in contact with the friction rod, and a second repulsive magnet is fixedly connected to the top of the movable plate. The movable plate can slide along the friction rod to achieve flexible position adjustment. The contact between the friction sleeves and the friction rod increases the friction between them, preventing the movable plate from sliding arbitrarily in the non-adjusted state and ensuring the stability of the movable plate's position. The second repulsive magnet and the first repulsive magnet repel each other, which can help adjust the force balance of the movable plate and make the movement of the movable plate more stable.

[0011] Preferably, a connecting pile is fixedly connected to the bottom of the movable plate, the bottom end of the connecting pile penetrates through the installation chamber and extends to the bottom of the installation chamber, and a movable frame is fixedly connected to the bottom end of the connecting pile. A pressure roller is rotatably connected to the inner side of the movable frame. The connecting pile connects the movable plate and the movable frame as one unit, so that the movement energy of the movable plate is synchronously transmitted to the movable frame, thereby driving the pressure roller to move. The pressure roller can press the material to ensure that the material remains flat during winding or transmission, reduce wrinkles, and improve the quality of material processing.

[0012] Preferably, the top of the mounting bracket is fixedly connected to four mounting seats, and the inner side of each mounting seat is fixedly connected to a mounting rod. The mounting seats provide stable mounting support for the mounting rods, ensuring that the position of the mounting rods is fixed. The mounting rods serve as guide components for the sliding of the connecting plate, ensuring the linearity and stability of the movement of the connecting plate, and laying the foundation for the precise positioning of the locking plate in the future.

[0013] Preferably, a compression spring is sleeved on the outer side of the mounting rod, and one end of the compression spring is fixedly connected to the mounting base. Two connecting plates are slidably connected to the outer side of the mounting rod. The compression spring can apply elastic pressure to the connecting plates, causing the connecting plates to tend to move inward, which facilitates the locking plate to make tight contact with the locking groove. The connecting plates can slide along the mounting rod to adjust their position, thereby adapting to the locking requirements of the rotating rod.

[0014] Preferably, a locking plate is fixedly connected to one side of the connecting plate, and a rubber pad is adhered to one side of the locking plate. The rubber pad contacts the snap-fit ​​groove, and a separating block is slidably connected to the top of the mounting base. Under the action of the pressure spring, the locking plate cooperates with the snap-fit ​​groove on the rotating rod to lock and fix the rotating rod, preventing it from rotating on its own during operation and ensuring the stability of the equipment operation. The rubber pad can increase the friction between the locking plate and the snap-fit ​​groove, improve the locking effect, and at the same time avoid the locking plate from directly contacting the rotating rod and causing wear. The separating block allows the operator to manually separate the connecting plate to the outside, making it convenient to adjust the position of the rotating rod, and the operation is simple and convenient.

[0015] This utility model provides an electroplating winding device with a bipolar current collector, which has the following beneficial effects: 1. This electroplating winding device for bipolar current collectors utilizes a pressure roller clamping mechanism. The pressure rollers provide stable clamping to the bipolar current collector during winding, effectively preventing wrinkles and misalignment caused by slack during transport and winding. This ensures the flatness of the current collector surface, thereby guaranteeing the uniformity of the electroplated layer and improving product quality. Simultaneously, the clamping force can be flexibly adjusted via clamping springs and repulsive magnets within the mounting chamber, adapting to bipolar current collectors of different thicknesses and materials. This enhances the device's versatility and applicability, reduces production failures caused by unstable current collector conditions, and improves production efficiency.

[0016] 2. This electroplating winding device for the bipolar current collector utilizes a rotating rod locking mechanism. This mechanism firmly secures the adjusted rotating rod, preventing it from rotating independently during equipment operation due to vibration, external forces, or other factors. This ensures the stability of the fixed frame and pressure rollers driven by the threaded rod, maintaining a constant pressure on the bipolar current collector. This not only avoids problems such as decreased winding accuracy and product quality fluctuations caused by a loose rotating rod, but also reduces downtime due to frequent equipment adjustments, improving production continuity and stability, and lowering maintenance costs. Furthermore, the rubber pads on the locking plate enhance the locking effect and prevent wear on the rotating rod, extending the equipment's service life. Attached Figure Description

[0018] This utility model provides an electroplating winding device with a bipolar current collector.

[0019] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the system includes a mounting frame 1, a take-up roller 101 rotatably connected to the inner side of the mounting frame 1, a motor 102 fixedly connected to one side of the mounting frame 1, one end of the power output shaft of the motor 102 passing through the mounting frame 1, and the other end of the power output shaft of the motor 102 being fixedly connected to the take-up roller 101, an anti-slip sleeve 103 being sleeved on the outer side of the take-up roller 101, and an anti-slip groove 104 being evenly distributed on the outer side of the anti-slip sleeve 103, and two rotating rods 2 rotatably connected to the top of the mounting frame 1, with locking grooves 201 being arranged sequentially from top to bottom on the outer side of the rotating rods 2.

[0020] Please refer to it again. Figure 1 , Figure 2 and Figure 3 The bottom end of the rotating rod 2 passes through the mounting frame 1 and extends to the inner side of the mounting frame 1. A threaded rod 3 is fixedly connected to the bottom end of the rotating rod 2. A fixing frame 301 is screwed to the outer side of the threaded rod 3. Four mounting chambers 4 are fixedly connected to the inner side of the fixing frame 301. Two friction rods 401 are fixedly connected to the inner side of the mounting chamber 4. A compression spring 402 is sleeved on the outer side of the friction rod 401. A first repulsive magnet 403 is fixedly connected to the top of the inner cavity of the mounting chamber 4. A moving plate 5 is slidably connected to the outer side of the friction rod 401. Two friction sleeves 501 are fixedly connected to the bottom of the moving plate 5. The friction sleeves 501 are in contact with the friction rods 401. A second repulsive magnet 502 is fixedly connected to the top of the moving plate 5. A connecting pile 503 is fixedly connected to the bottom of the moving plate 5. The bottom end of the connecting pile 503 passes through the mounting chamber 4 and extends to the bottom of the mounting chamber 4. A moving frame 6 is fixedly connected to the bottom end of the connecting pile 503. A pressure roller 601 is rotatably connected to the inner side of the moving frame 6.

[0021] The friction rod 401 inside the mounting chamber 4 provides a sliding guide for the moving plate 5. When the moving plate 5 is moved by force, the second repulsive magnet 502 at its top and the first repulsive magnet 403 at the top of the inner cavity of the mounting chamber 4 generate a repulsive force. At the same time, the compression spring 402 on the outside of the friction rod 401 applies elastic pressure to the moving plate 5. The two work together to adjust the position of the moving plate 5. The friction sleeve 501 at the bottom of the moving plate 5 contacts the friction rod 401, and the friction force limits the unexpected sliding of the moving plate 5, ensuring its positional stability. The moving plate 5 is connected to the moving frame 6 through the connecting pile 503. When the moving plate 5 moves up and down, it will drive the moving frame 6 to move synchronously, thereby adjusting the up and down position of the pressure roller 601 on the inner side of the moving frame 6. Finally, the pressure generated by the contact between the pressure roller 601 and the material achieves the pressing effect on the material.

[0022] Example 2, as Figure 1 , Figure 2 and Figure 4As shown, four mounting seats 7 are fixedly connected to the top of the mounting bracket 1. Mounting rods 701 are fixedly connected to the inner side of the mounting seats 7. A pressure spring 702 is sleeved on the outer side of the mounting rod 701, and one end of the pressure spring 702 is fixedly connected to the mounting seat 7. Two connecting plates 703 are slidably connected to the outer side of the mounting rod 701. A locking plate 8 is fixedly connected to one side of the connecting plate 703. A rubber pad 801 is glued to one side of the locking plate 8. The rubber pad 801 is in contact with the snap-fit ​​groove 201. A separation block 9 is slidably connected to the top of the mounting seat 7.

[0023] The mounting rod 701 on the inner side of the mounting base 7 provides sliding support for the connecting plate 703. One end of the pressure spring 702 on its outer side is fixed to the mounting base 7, and the other end applies an inward elastic pressure to the connecting plate 703, causing the connecting plate 703 to move the locking plate 8 closer to the rotating rod 2. The rubber pad 801 on one side of the locking plate 8 contacts the snap-fit ​​groove 201 on the outer side of the rotating rod 2. Under the elastic force of the pressure spring 702, the rubber pad 801 is tightly embedded in the snap-fit ​​groove 201, and the rotation of the rotating rod 2 is restricted by friction to achieve locking. When it is necessary to release the lock, the separating block 9 on the top of the sliding mounting base 7 is slidable. The separating block 9 pushes the connecting plate 703 to slide outward along the mounting rod 701, so that the locking plate 8 is disengaged from the snap-fit ​​groove 201, and the restriction on the rotating rod 2 is released.

[0024] Working principle: The friction rod 401 inside the installation chamber 4 provides sliding guidance for the moving plate 5. When the moving plate 5 is moved under force, the second repulsive magnet 502 at its top and the first repulsive magnet 403 at the top of the inner cavity of the installation chamber 4 generate a repulsive force. At the same time, the compression spring 402 on the outside of the friction rod 401 applies elastic pressure to the moving plate 5. The two work together to adjust the position of the moving plate 5. The friction sleeve 501 at the bottom of the moving plate 5 contacts the friction rod 401, limiting the unexpected sliding of the moving plate 5 through friction and ensuring its positional stability. The moving plate 5 is connected to the moving frame 6 through the connecting pile 503. When the moving plate 5 moves up and down, it drives the moving frame 6 to move synchronously, thereby adjusting the up and down position of the pressure roller 601 on the inner side of the moving frame 6. Finally, the pressure roller 601 in contact with the material generates pressure. The force compresses the material. The mounting rod 701 on the inner side of the mounting base 7 provides sliding support for the connecting plate 703. One end of the pressure spring 702 on its outer side is fixed to the mounting base 7, and the other end applies an inward elastic pressure to the connecting plate 703, causing the connecting plate 703 to move the locking plate 8 closer to the rotating rod 2. The rubber pad 801 on one side of the locking plate 8 contacts the snap-fit ​​groove 201 on the outer side of the rotating rod 2. Under the elastic force of the pressure spring 702, the rubber pad 801 is tightly embedded in the snap-fit ​​groove 201, and the rotation of the rotating rod 2 is restricted by friction to achieve locking. When it is necessary to release the lock, the separating block 9 on the top of the sliding mounting base 7 pushes the connecting plate 703 to slide outward along the mounting rod 701, so that the locking plate 8 is disengaged from the snap-fit ​​groove 201, and the restriction on the rotating rod 2 is released.
