Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and in particular to an adaptive tension copper foil winding device. Background Technology

[0002] Copper foil winding equipment is a key piece of equipment used in electronics manufacturing, battery production, and other fields to roll copper foil raw materials into finished coils according to specific specifications. It is defined as an automated device that, through the coordinated operation of power drive, tension control, and guiding positioning systems, uniformly winds continuously produced copper foil strips into coils with a fixed diameter and stable tension. The equipment typically includes core components such as a frame, winding rollers, guide roller assembly, tension detection unit, drive motor, and control system. The guide roller assembly is responsible for guiding the copper foil along its path and adjusting its tension, ensuring the copper foil remains flat and wrinkle-free during winding. The tension detection unit monitors the copper foil tension in real time and adjusts the drive motor speed through feedback from the control system to achieve constant tension winding.

[0003] Currently, to adapt to the winding requirements of copper foil of different widths, copper foil winding equipment is generally equipped with an adaptive tension mechanism consisting of multiple guide rollers to adapt to different specifications of copper foil. However, when it is necessary to change the width of the copper foil, the existing mechanism exposes a significant operational bottleneck: the guide rollers are usually installed with fixed shafts or bolted connections. When replacing them, the original guide rollers must be disassembled one by one, and then guide rollers of the corresponding length must be reinstalled according to the new copper foil width. The operation is cumbersome and time-consuming. Therefore, it is necessary to design an adaptive tension copper foil winding equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this invention is to provide an adaptive tension copper foil winding device to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides an adaptive tension copper foil winding device, including a support plate. A linear array of first and second support plates is fixedly mounted on the top surface of the support plate via bolts. A motor is fixedly connected to one side of the first support plate, and a winding frame is fixedly connected to the output end of the motor. Two symmetrically arranged first pins are fixedly connected to one side of the second support plate. An electric push rod is fixedly connected to the top surface of the support plate, and an assembly plate is fixedly connected to the output end of the electric push rod. A U-shaped assembly frame is slidably connected to the outer surface of the assembly plate. Springs are fixedly connected to the left and right sides of the U-shaped assembly frame. A locking pin is fixedly connected to the end of the spring away from the U-shaped assembly frame. Both locking pins penetrate the U-shaped assembly frame and engage with the assembly plate. A second pin is fixedly connected to the front of the U-shaped assembly frame. An adjusting roller is rotatably connected to the outer surface of the second pin via a bearing. A connecting plate is fixedly connected to the top surface of the U-shaped assembly frame. A mounting plate is slidably connected to the outer surface of the connecting plate. Two symmetrically arranged locking bolts are rotatably connected to one side of the mounting plate. The threaded portions of the two locking bolts are threadedly connected to the second support plate. Two symmetrically arranged guide rollers are fixedly connected to the front of the mounting plate. The two guide rollers are slidably connected to the two first pins respectively.

[0007] Preferably, in any of the above solutions, the front side of the second support plate has two symmetrically arranged threaded holes, and the screw portions of the two locking bolts are threadedly connected to the second support plate through the threaded holes.

[0008] Preferably, in any of the above solutions, a limiting frame is fixedly connected to the front of the second support plate, and the mounting plate is slidably connected to the limiting frame.

[0009] Preferably, in any of the above solutions, the top of the assembly plate is fixedly connected with two symmetrically arranged positioning pins, and the U-shaped assembly frame is engaged with the assembly plate through the positioning pins.

[0010] Preferably, from any of the above solutions, locking holes are provided on both the left and right sides of the assembly plate, and the two locking pins pass through the U-shaped assembly frame and are engaged with the assembly plate through the locking holes.

[0011] Preferably, in any of the above schemes, a blocking disc is fixedly connected to the outer surface of each first pin, and the side of the guide roller near the second support plate is in contact with the blocking disc.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0013] 1. When it is necessary to change to copper foil of different widths for winding, this equipment can simultaneously disassemble and install two guide rollers and one adjusting roller. First, loosen the locking bolts on the mounting plate to disengage it from the threaded hole of the second support plate. At this time, the mounting plate is no longer fixed. Since the mounting plate and the connecting plate are slidably connected, and the U-shaped assembly frame is also slidably connected to the assembly plate, and the locking pin passes through the locking hole of the U-shaped assembly frame and the assembly plate, pull the U-shaped assembly frame to overcome the spring force and drive the locking pin to disengage from the locking hole. At the same time, the U-shaped assembly frame slides away from the assembly plate along the positioning pin. At this time, the adjusting roller connected to the U-shaped assembly frame and the two guide rollers connected to the mounting plate are disassembled together. After replacing the adjusting roller and guide roller assembly with the appropriate width of the new copper foil, reverse the above steps, align the U-shaped assembly frame with the positioning pin on the assembly plate and insert it. The spring pushes the locking pin to re-engage into the locking hole. Then slide the mounting plate back along the limit frame and tighten the locking bolts to complete the quick installation, greatly improving the replacement efficiency.

[0014] 2. The electric push rod moves the assembly plate, which in turn moves the adjusting roller on the U-shaped assembly frame, thus changing the tension of the copper foil during the winding process. The cooperation of the spring and the locking pin ensures that the U-shaped assembly frame remains stable during the movement and adjustment, preventing it from wobbling. When the copper foil tension changes, the force exerted by the copper foil on the adjusting roller is transmitted to the spring through the U-shaped assembly frame. The spring undergoes elastic deformation to buffer the change, allowing the adjusting roller to automatically adjust its position according to the actual tension of the copper foil, thereby achieving adaptive tension adjustment. Simultaneously, the guide roller is slidably connected to the first pin and is in contact with the blocking disc, ensuring stable guidance of the copper foil during transport and preventing it from deviating. Combined with the tension adjustment of the adjusting roller, the copper foil tension remains stable throughout the winding process, ensuring the quality and efficiency of copper foil winding.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0022] like Figures 1 to 5 As shown, an adaptive tension copper foil winding device includes a support plate 1. A linear array of first support plates 2 and second support plates 3 are bolted to the top surface of the support plate 1. A motor 4 is fixedly connected to one side of the first support plate 2, and a winding frame 5 is fixedly connected to the output end of the motor 4. Two symmetrically arranged first pins 6 are fixedly connected to one side of the second support plate 3. An electric push rod 7 is fixedly connected to the top surface of the support plate, and an assembly plate 8 is fixedly connected to the output end of the electric push rod 7. A U-shaped assembly frame 9 is slidably connected to the outer surface of the assembly plate 8. Springs 10 are fixedly connected to both the left and right sides of the U-shaped assembly frame 9, with the end of each spring 10 furthest from the U-shaped assembly frame 9 fixedly connected to... There is a locking pin 11, and both locking pins 11 pass through the U-shaped assembly frame 9 and are engaged with the assembly plate 8. The front of the U-shaped assembly frame 9 is fixedly connected to a second pin 12. The outer surface of the second pin 12 is rotatably connected to an adjusting roller 13 via a bearing. The top surface of the U-shaped assembly frame 9 is fixedly connected to a connecting plate 14. The outer surface of the connecting plate 14 is slidably connected to a mounting plate 15. One side of the mounting plate 15 is rotatably connected to two symmetrically arranged locking bolts 16. The screw parts of the two locking bolts 16 are threadedly connected to the second support plate 3. The front of the mounting plate 15 is fixedly connected to two symmetrically arranged guide rollers 17. The two guide rollers 17 are slidably connected to the two first pins 6 respectively.

[0023] As an optional technical solution of this utility model, the second support plate 3 has two symmetrically arranged threaded holes 18 on its front side. The screws of the two locking bolts 16 are threadedly connected to the second support plate 3 through the threaded holes 18. During the operation of the copper foil winding equipment, this connection structure can effectively restrict the movement of the mounting plate 15, ensuring that the guide roller 17 on the mounting plate 15 is fixed in position, so that the copper foil maintains a stable guiding path during transmission. When it is necessary to adjust the position of the guide roller 17 or replace copper foil of different specifications, it is only necessary to loosen the locking bolts 16 to release the fixed state of the mounting plate 15. The operation is simple and convenient, ensuring the stability of equipment operation while taking into account the flexibility of use.

[0024] As an optional technical solution of this utility model, a limiting frame 19 is fixedly connected to the front of the second support plate 3, and the mounting plate 15 is slidably connected to the limiting frame 19. When adjusting the position of the guide roller 17, the mounting plate 15 can slide smoothly along the trajectory of the limiting frame 19, avoiding deviation or shaking, and ensuring that the guide roller 17 is always in the correct working position during the adjustment process, thereby ensuring the accuracy of the copper foil transmission path. At the same time, the limiting frame 19 can also prevent the mounting plate 15 from being displaced due to vibration and other factors during equipment operation, further enhancing the stability and reliability of the overall structure of the equipment.

[0025] As an optional technical solution of this utility model, the top of the assembly plate 8 is fixedly connected with two symmetrically arranged positioning pins 20. The U-shaped assembly frame 9 is engaged with the assembly plate 8 through the positioning pins 20. This engagement structure not only simplifies the installation process of the U-shaped assembly frame 9, but also ensures that the positioning pins 20 limit the U-shaped assembly frame 9 during equipment operation, allowing it to remain stable and prevent positional displacement under external forces such as copper foil tension. Simultaneously, the cooperation between the positioning pins 20 and the U-shaped assembly frame 9 provides a stable support foundation for the spring 10 and the locking pin 11, contributing to improved working stability of the entire adaptive tension adjustment mechanism.

[0026] As an optional technical solution of this utility model, locking holes 21 are provided on both the left and right sides of the assembly plate 8. Two locking pins 11 pass through the U-shaped assembly frame 9 and are engaged with the assembly plate 8 through the locking holes 21. The spring 10 pushes the locking pins 11 into the locking holes 21, so that the U-shaped assembly frame 9 is firmly fixed on the assembly plate 8. During the copper foil winding process, even if the copper foil tension changes, the U-shaped assembly frame 9 will not move arbitrarily due to force, ensuring that the adjusting roller 13 is always in a suitable working position for tension adjustment. When it is necessary to disassemble the U-shaped assembly frame 9, simply overcome the elastic force of the spring 10 and pull out the locking pins 11, which is convenient and quick to operate.

[0027] As an optional technical solution of this utility model, a blocking disc 22 is fixedly connected to the outer surface of each first pin 6. The side of the guide roller 17 near the second support plate 3 is in contact with the blocking disc 22. The blocking disc 22 on the outer surface of the first pin 6 is in contact with the guide roller 17, which can effectively prevent the guide roller 17 from axially shifting during copper foil transmission. When the copper foil is wound up, the force exerted by the copper foil on the guide roller 17 is complex and variable. By restricting the axial movement of the guide roller 17, the blocking disc 22 ensures that the guide roller 17 always guides the copper foil in the correct direction, so that the copper foil can be smoothly and accurately transmitted to the winding frame 5, avoiding problems such as copper foil deviation and wrinkling caused by the positional deviation of the guide roller 17.

[0028] An adaptive tension copper foil winding device, the working principle of which is as follows:

[0029] 1) First, loosen the locking bolts 16 on the mounting plate 15 so that they are disengaged from the threaded holes 18 of the second support plate 3. At this time, the mounting plate 15 will no longer be fixed.

[0030] 2): Since the mounting plate 15 and the connecting plate 14 are slidably connected, the U-shaped assembly frame 9 is also slidably connected to the assembly plate 8, and the locking pin 11 passes through the locking hole 21 of the U-shaped assembly frame 9 and is engaged with the locking hole 21 of the assembly plate 8. Pulling the U-shaped assembly frame 9 will overcome the elastic force of the spring 10 and drive the locking pin 11 to disengage from the locking hole 21.

[0031] 3): The U-shaped assembly frame 9 slides away from the assembly plate 8 along the positioning pin 20. At this time, the adjusting roller 13 connected to the U-shaped assembly frame 9 and the two guide rollers 17 connected to the mounting plate 15 are disassembled together.

[0032] In summary, this adaptive tension copper foil winding device first loosens the locking bolts 16 on the mounting plate 15, disengaging them from the threaded holes 18 of the second support plate 3, at which point the mounting plate 15 is no longer fixed. Since the mounting plate 15 is slidably connected to the connecting plate 14, and the U-shaped assembly frame 9 is slidably connected to the assembly plate 8, and the locking pin 11 penetrates the U-shaped assembly frame 9 and engages with the locking hole 21 of the assembly plate 8, pulling the U-shaped assembly frame 9 overcomes the elastic force of the spring 10, causing the locking pin 11 to disengage from the locking hole 21. Simultaneously, the U-shaped assembly frame 9 slides away from the assembly plate 8 along the positioning pin 20. At this point, the adjusting roller 13 connected to the U-shaped assembly frame 9 and the two guide rollers 17 connected to the mounting plate 15 are disassembled together. After replacing the adjusting roller 13 and guide roller 17 assemblies with those adapted to the new copper foil width, reverse the above steps. Align the U-shaped assembly frame 9 with the positioning pin 20 on the assembly plate 8 and insert it. The spring 10 pushes the locking pin 11 to re-engage into the locking hole 21. Then, slide the mounting plate 15 back along the limit frame 19 and tighten the locking bolt 16 to complete the quick installation, greatly improving replacement efficiency. The electric push rod 7 pushes the assembly plate 8 to move, which in turn moves the adjusting roller 13 on the U-shaped assembly frame 9, changing the tension of the copper foil during the winding process. The cooperation between the spring 10 and the locking pin 11 ensures that the U-shaped assembly frame 9 remains stable during the adjustment process and does not wobble. When the copper foil tension changes, the force exerted by the copper foil on the adjusting roller 13 is transmitted to the spring 10 through the U-shaped assembly frame 9. The spring 10 undergoes elastic deformation to buffer the change, allowing the adjusting roller 13 to automatically adjust its position according to the actual tension of the copper foil, thereby achieving adaptive tension adjustment. Meanwhile, the guide roller 17 is slidably connected to the first pin 6, and the guide roller 17 is in contact with the blocking disc 22, which ensures the stable guidance of the copper foil during the transmission process and prevents the copper foil from deviating. Combined with the tension adjustment of the adjusting roller 13, the tension of the copper foil is kept stable throughout the winding process, ensuring the quality and efficiency of copper foil winding.
