[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a release film winding structure for OCA adhesive film replacement, comprising a support column 1, a group of symmetrical winding rollers 2 are arranged on the opposite sides of the support column 1, and the outer sides of the winding rollers 2 are wrapped with film bodies 3, the inner sides of the support columns 1 are fixedly connected with a group of symmetrical accommodating columns 4, and one end of the accommodating columns 4 is movably connected with a buffer column 5, a rotating mechanism 6 is arranged inside the buffer column 5 for controlling the rotation of the winding roller 2, a connecting mechanism 7 is arranged on the outer side of the buffer column 5 for connecting the rotating mechanism 6 with the winding roller 2, and a group of symmetrical pressure regulating mechanisms 8 are arranged on the opposite sides of the support column 1 for adjusting the winding pressure of the release film.
[0022] The winding roller 2 is placed on the opposite side of the buffer column 5 . The end of the buffer column 5 is designed with an arc-shaped support block for placing the winding roller 2 .
[0023] like Figure 1 and Figure 4As shown, the rotating mechanism 6 includes a cross bar 601, a connecting tube 602 and a rotating column 603. The cross bar 601 passes through the connecting tube 602, and the cross bar 601 is movably connected to the connecting tube 602. One end of the cross bar 601 is movably connected to the inside of the rotating column 603. One end of the rotating column 603 movably passes through the buffer column 5 and the accommodating column 4. The inside of the accommodating column 4 is fixedly connected with a buffer spring 9, and the free end of the buffer spring 9 is fixedly connected with a spacer ring 10. The other end of the spacer ring 10 is fitted with the end of the buffer column 5, and the rotating column 603 passes through the spacer ring 10 and the buffer spring 9. The outer side of the support column 1 is fixedly connected with a group of symmetrical support blocks 11, and the top of the support block 11 is fixedly connected with a servo motor 12. The output end of the servo motor 12 is fixedly connected to one end of the rotating column 603.
[0024] Start the servo motor 12 to drive the rotating column 603 to rotate. Under the action of the cross bar 601, the winding roller 2 rotates synchronously. When the winding roller 2 is subjected to lateral vibration, the buffer column 5 moves laterally, causing the spacer ring 10 to move laterally, so that the buffer spring 9 absorbs the vibration, thereby reducing the lateral deviation of the winding roller 2, which is conducive to keeping the ends of the film body 3 flush after the film body 3 is completed.
[0025] like Figure 1 and Figure 4 As shown, the connecting mechanism 7 includes a movable ring 701, a connecting block 702 and a hydraulic rod 703. The buffer column 5 passes through the movable ring 701, and the buffer column 5 is movably connected to the movable ring 701. The connecting block 702 is fixedly connected to the outer side of the movable ring 701. The hydraulic rod 703 is fixedly connected to the outer side of the buffer column 5, and the telescopic end of the hydraulic rod 703 is fixedly connected to one side of the connecting block 702. The connecting tube 602 passes through the center of the movable ring 701, and the connecting tube 602 is movably connected to the movable ring 701 through a bearing.
[0026] Start the hydraulic rod 703 to push the connecting block 702 to move, thereby driving the movable ring 701 to move along the buffer column 5, thereby driving the connecting tube 602 to move inside the buffer column 5, thereby controlling the cross bar 601 to be inserted into the cross groove at the end of the winding roller 2, thereby quickly completing the installation and disassembly of the winding roller 2.
[0027] like Figure 1 and Figure 2 As shown, the pressure regulating mechanism 8 includes a pressure regulating rod 801, a bracket 802 and a servo motor 2 803. The pressure regulating rod 801 is movably connected to the inner side of the bracket 802, and the bracket 802 is rotatably connected to the opposite side of the support column 1. The servo motor 2 803 is fixedly connected to the outer side of the support column 1, and the output end of the servo motor 2 803 is fixedly connected to the rotating shaft of the bracket 802. The outer side of the pressure regulating rod 801 is in contact with the membrane body 3.
[0028] As the film 3 is wound more and more on the outside of the winding roller 2, the overall diameter of the winding roller 2 increases. By starting the servo motor 803, the bracket 802 is driven to rotate, thereby adjusting the pressure of the pressure regulating rod 801 on the film 3, thereby ensuring that the winding tension of the film 3 remains consistent and avoiding loosening after the film 3 is unfolded.
[0029] Working principle: When in use, first, place the winding roller 2 on the opposite side of the buffer column 5. The end of the buffer column 5 is designed with an arc-shaped support block for placing the winding roller 2. Then start the hydraulic rod 703 to push the connecting block 702 to move, thereby driving the moving ring 701 to move along the buffer column 5, thereby driving the connecting cylinder 602 to move inside the buffer column 5, thereby controlling the cross bar 601 to insert into the cross groove at the end of the winding roller 2. Then, start the servo motor 12 to drive the rotating column 603 to rotate. Under the action of the cross bar 601, the winding roller 2 rotates synchronously, and when the winding roller 2 is subjected to lateral vibration, the buffer column 5 moves laterally, causing the spacer ring 10 to move laterally, thereby allowing the buffer spring 9 to absorb the vibration, thereby reducing the lateral deviation of the winding roller 2, and as the film body 3 is wound more and more on the outside of the winding roller 2, the overall diameter of the winding roller 2 increases. By starting the servo motor 2 803, the bracket 802 is driven to rotate, thereby adjusting the pressure of the pressure regulating rod 801 on the film body 3, thereby ensuring that the winding tension of the film body 3 remains consistent.
