[0002] Flexible printed circuit boards (FPCs) are widely used in smartphones, wearable devices, automotive electronics, and medical devices due to their thinness, flexibility, and bending resistance. Unlike the sheet processing of traditional rigid circuit boards, FPCs are usually produced and processed in roll form. The core function of the winding equipment is to achieve precise unwinding, rewinding, tension control, and transmission of FPC rolls, which solves the problems of easy wrinkling, stretching deformation, and inaccurate positioning of flexible materials during processing.

[0003] The working principle of flexible printed circuit board winding equipment is to achieve precise delivery of the roll material, stable tension control, and coordinated operation of winding and unwinding through the coordinated cooperation of mechanical structure, sensing system and control system. Tension control is the key link. Tension sensor provides real-time feedback of tension value, controller uses PID algorithm to adjust the speed of winding and unwinding motor, plus the mechanical buffer of swing roller, to stabilize the tension within the set range and prevent the roll material from wrinkling or breaking.

[0004] In existing technologies, some equipment requires manual application of flexible circuit boards onto a roll. When applying the boards manually, it is difficult to ensure precise alignment between the circuit board and the roll, which may result in misalignment or skewing. This leads to inconsistent product dimensions after winding, affecting subsequent assembly or use. Therefore, a flexible circuit board winding device is proposed to solve the above problems. Utility Model Content

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figures 1 to 3This utility model provides an embodiment of a flexible circuit board winding device, including a support plate 1. The support plate 1 serves as the basic frame of the device, supporting core components such as a motor 2 and a rotating disk 10, and providing installation reference and motion guidance for each component. The motor 2 is fixedly connected to the inner wall of the support plate 1. The motor 2 drives the threaded rod 3 to rotate, causing the transmission plate 4 to slide along the inner wall of the support plate 1, thereby realizing the lateral position adjustment of the adsorption mechanism. The drive end of the motor 2 is fixedly connected to the threaded rod 3, and the threaded rod 3 is connected to the drive end of the motor 2, converting the rotational motion of the motor 2 into the linear motion of the transmission plate 4.

[0013] The threaded rod 3 is externally threaded to a transmission plate 4, which provides installation conditions for internal components. A second motor 5 is fixedly connected to the inner wall of the transmission plate 4. The second motor 5 drives the first gear 6 to rotate. Through gear and rack meshing, the first rack 7 and subsequent connecting plate 8 and suction cup 9 move up and down. The drive end of the second motor 5 is fixedly connected to the first gear 6. The first gear 6 is fixedly connected to the drive end of the second motor 5, transmitting the rotational motion of the second motor 5 to the first rack 7. The inner wall of the transmission plate 4 is slidably connected to the first rack 7. The first rack 7 meshes with the first gear 6 and is driven by the first gear 6 to slide vertically up and down. The bottom is connected to the connecting plate 8, which drives the connecting plate 8 and suction cup 9 to rise and fall synchronously through its own sliding.

[0014] The outer side of rack 7 is meshed with the outer side of gear 6. The inner wall of support plate 1 is equipped with a mounting component that facilitates the installation of the drum. The bottom of rack 7 is fixedly connected to a connecting plate 8. The connecting plate 8 connects rack 7 and suction cup 9, transmitting the up and down movement of rack 7 to suction cup 9, and providing a mounting surface for multiple suction cups 9. Multiple suction cups 9 are fixedly connected to the bottom of connecting plate 8. The suction cups 9 adsorb the flexible circuit board through negative pressure. The outer wall of transmission plate 4 is slidably connected to the inner wall of support plate 1. One end of threaded rod 3 is rotatably connected to the inner wall of support plate 1. Reference Figure 1 , Figure 4 and Figure 5 The mounting components include a motor 11, which drives the rotating disk 10 to rotate. The outer wall of the motor 11 is fixedly connected to the inner wall of the support plate 1. The drive end of the motor 11 is fixedly connected to the rotating disk 10. The rotating disk 10 serves as the carrier for the installation and rotation of the drum. It is connected to the drive end of the motor 11 to drive the drum to rotate and realize the winding operation. The outer wall of the rotating disk 10 is rotatably connected to the outer wall of the support plate 1. The inner wall of the rotating disk 10 is rotatably connected to a transmission rod 13. The transmission rod 13 connects the gear 12 and the rotating plate 14, transmitting the rotational motion of the gear 12 to the rotating plate 14, thereby driving the rotating plate 14 to rotate.

[0015] A gear 12 is fixedly connected to the outer wall of the transmission rod 13. The gear 12 meshes with the rack 19 and is driven to rotate by the rack 19. At the same time, it is fixedly connected to the transmission rod 13, converting the linear motion of the rack 19 into the rotational motion of the transmission rod 13. A cylinder 18 is fixedly connected to the inner wall of the rotating disk 10. The cylinder 18 drives the rack 19 to slide. The driving end of the cylinder 18 is fixedly connected to the rack 19. The rack 19 meshes with the gear 12 and is driven by the cylinder 18 to slide linearly, transmitting the linear power of the cylinder 18 to the gear 12. The outer side of the rack 19 and the outer side of the gear 12 are meshed and connected. The outer wall of the rack 19 is slidably connected to the inner wall of the rotating disk 10. A rotating plate 14 is fixedly connected to one end of the transmission rod 13. The rotating plate 14 is driven by the transmission rod 13 to drive the connecting column 15.

[0016] Multiple connecting columns 15 are fixedly connected to the outer wall of the rotating plate 14. The connecting columns 15 connect the rotating plate 14 and the connecting block 16. When the rotating plate 14 rotates, it pushes the connecting block 16. Multiple connecting blocks 16 are rotatably connected to the outer wall of the multiple connecting columns 15. The connecting block 16 transmits the thrust of the connecting column 15 to the sliding column 17. Multiple sliding columns 17 are rotatably connected to the inner wall of the multiple connecting blocks 16. The sliding column 17 is pushed by the connecting block 16 and slides on the inner wall of the rotating disk 10, causing the support block 20 to move radially synchronously. Multiple support blocks 20 are fixedly connected to the outer wall of the multiple sliding columns 17. The support block 20 contacts the drum and achieves radial expansion and contraction through the sliding column 17. When expanding, it tightens the inner wall of the drum to complete the fixation. When contracting, it loosens the drum for easy loading and unloading. The outer walls of the multiple sliding columns 17 are slidably connected to the inner wall of the rotating disk 10.

[0017] Working principle: When the flexible circuit board needs to be wound, motor 5 is started, and its drive end drives gear 6 to rotate counterclockwise. Gear 6 drives rack 7, which meshes with it, to slide downward, causing connecting plate 8 to move down synchronously. This allows suction cup 9 at the bottom to contact and hold the flexible circuit board on the conveyor belt. Then, motor 2 is started, and its drive end drives threaded rod 3 to rotate. Threaded rod 3 drives transmission plate 4 to slide along the inner wall of support plate 1 through threaded transmission, moving the adsorbed flexible circuit board to the outside of support block 20, directly above the drum. At this time, rack 7 continues to slide down, placing the flexible circuit board on the surface of the drum. Then, motor 5 reverses, driving rack 7 to slide upward and reset, preventing suction cup 9 from obstructing subsequent winding actions. Finally, motor 11 is started, and its drive end drives rotating disk 10 to rotate, causing the drum to rotate synchronously and starting the winding operation of the flexible circuit board. This structure can automatically and accurately cover the flexible circuit board onto the drum, eliminating the tedious steps of manual placement, reducing the positional deviation that may be caused by manual operation, and ensuring the alignment accuracy at the beginning of the winding process.

[0018] When the drum needs to be installed, the drum is placed on the support block 20. Then, the cylinder 18 is activated. The drive end of the cylinder 18 drives the rack 19 to slide. The rack 19 drives the gear 12 that meshes with it to rotate. The gear 12 drives the transmission rod 13. The transmission rod 13 drives the rotating plate 14 to rotate. The rotating plate 14 drives the connecting post 15 on its surface edge. The connecting post 15 drives the connecting block 16. The connecting block 16 then drives the sliding post 17 to slide on the inner wall of the rotating disk 10. When the sliding post 17 slides, it drives the support block 20 to expand, supporting the drum and completing the fixation of the drum. Conversely, the drum can be removed. This structure can flexibly adjust the expansion range of the support block 20 and can be adapted to drums of different diameters. There is no need to change the special clamps for drums of different sizes, which reduces the cost of equipment use and improves the efficiency of drum installation and replacement.
