[0007] Conductive films may experience bottom wrinkles, which occur only in the initial length of the film winding process. These wrinkles manifest as numerous and deep wrinkles and streaks, and are caused by a variety of factors. For example, the setting methods, approaches, and values of process parameters differ depending on the type of winding machine. The performance of the equipment itself and the inherent properties of the film have a significant impact on the quality of film slitting and winding. Summary of the Invention

[0014] An adjusting plate is fixed between the two sliders, with its lower end positioned directly above the take-up shaft, and the lower end of the adjusting plate having rounded corners.

[0018] In a preferred embodiment of the present invention, the lower end of the adjusting plate is rotatably connected to a first roller.
[0019] In a preferred embodiment of the present invention, piston cylinders are provided at both ends of the adjusting plate, and a piston rod is slidably connected inside the piston cylinder; the piston cylinder is fixedly connected inside the first sliding groove, the piston rod is connected to the slider inside the first sliding groove, and the air outlet of the piston cylinder is located at the lower end of the adjusting plate.
[0020] As a preferred embodiment of the present invention, the air outlet of the piston cylinder is a duckbill-shaped outlet, and the diameter of the end of the air outlet away from the piston cylinder is small.
[0021] In a preferred embodiment of the present invention, a rectangular groove is provided inside the cutting plate, and a limiting block is slidably connected inside the rectangular groove by a spring; a top plate is fixedly connected to the machine body, and when the cutting plate moves downward, the limiting block contacts the top plate.

[0026] Because the side of the adjusting plate meshes with the gear, when the adjusting plate moves upward, it meshes with the gear, which in turn contacts one end of the cutting plate. Therefore, when the adjusting plate moves upward inside the first slide groove, it meshes with the gear, causing the gear to rotate clockwise. This clockwise rotation meshes with the cutting plate, causing it to move downward through the gear's meshing action. During this downward movement, the cutting blade at the lower end of the cutting plate cuts the conductive film. After the conductive film is cut, the operator removes the wound conductive film from the winding shaft. This mechanical mechanism automatically cuts the conductive film after winding, avoiding the need for CNC programming or additional controllers. A separate controller controls a single cutting blade to cut the conductive film, thus ensuring cutting accuracy while reducing the failure rate. Attached Figure Description

Detailed Implementation
[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0035] Transparent conductive films are optoelectronic materials that combine optical transparency and conductivity, and are widely used in optoelectronic devices such as touch screens, liquid crystal displays, light-emitting diodes, and solar cells.
[0036] Currently, the materials used for transparent electrodes are mainly transparent conductive oxides, with tin oxide being the most common.
[0037] Metal mesh technology uses metallic materials such as silver and copper to grow conductive metal mesh patterns on plastic films such as glass or PET. Metal mesh has a lower resistivity than ITO, can be produced roll to roll, and has good bending resistance, making it suitable for flexible devices.
[0038] During the manufacturing and production of conductive films, processes such as winding and slitting are required. Winding involves using a winding machine to roll the completed conductive film sheets into a cylindrical shape.
[0039] However, the following problems may occur during the winding process of conductive films;
[0040] Conductive films may experience bottom wrinkles, which occur only in the initial length of the film winding process. These wrinkles manifest as numerous and deep wrinkles and streaks, and are caused by a variety of factors. For example, the setting methods, approaches, and values of process parameters differ depending on the type of winding machine. The performance of the equipment itself and the inherent properties of the film have a significant impact on the quality of film slitting and winding.
[0041] Example 1
[0042] like Figures 1-6 As shown; a metal mesh transparent conductive film processing equipment, including a conductive film winding device; the conductive film winding device includes;
[0043] Body 1; A gap is provided between the two ends of the body 1;
[0044] A drive device 11 is disposed on one side of the machine body 1 and is rotatably connected to the machine body 1; a take-up shaft 12 is provided at the end of the drive device 11, and the end of the take-up shaft 12 away from the drive device 11 is located at the end of the machine body 1 away from the drive device 11.
[0045] The first slide groove 13 is formed on the opposite surfaces of the two end bodies 1; a slider is slidably connected inside the first slide groove 13.
[0046] Adjusting plate 14, the adjusting plate 14 is fixed between the two sliders, the lower end of the adjusting plate 14 is located directly above the winding shaft 12, and the lower end of the adjusting plate 14 has rounded corners;
[0047] Gear 15, which is rotatably connected between the two machine bodies 1, and meshes with the side of the adjusting plate 14;
[0048] The second slide groove 16 is formed on the opposite sides of the two ends of the machine body 1. The cutting plate 17 is slidably connected inside the second slide groove 16 by a slider. The cutting plate 17 meshes with the gear 15.
[0049] The take-up shaft 12 has a placement groove 121 at one end away from the drive device 11. The take-up shaft 12 is located inside the placement groove 121. An annular groove 122 is provided inside the placement groove 121. An annular plate 123 is slidably connected inside the annular groove 122. The annular plate 123 is semi-circular.
[0050] The lower end of the adjusting plate 14 is rotatably connected to a first roller 141.
[0051] The specific workflow is as follows;
[0052] Before starting the winding machine, the operator holds the handle on the side of the annular plate 123 and rotates it counterclockwise. This rotation causes the annular plate 123 to rotate counterclockwise within the annular groove 122. As the annular plate 123 rotates counterclockwise, the end of the annular plate 123 inside the placement groove 121 no longer obstructs it. The operator then manually retracts the winding shaft 12 from the end inside the placement groove 121. Since the drive device 11 is rotatably connected to the machine body 1, the operator can manually lift the winding shaft 12 from the placement groove 12. 1. The internal rotation is initiated, at which point the drive device 11 rotates on the machine body 1. The drive device 11 is a drive motor. After the take-up shaft 12 rotates from inside the placement groove 121, the operator puts the sleeve for winding the conductive film onto the take-up shaft 12. Then, the operator manually moves one end of the take-up shaft 12 into the placement groove 121. Subsequently, the operator controls the annular plate 123, which rotates clockwise inside the annular groove 122. The annular plate 123 then closes the opening of the placement groove 121 again, preventing the take-up shaft 12 from sliding out of the placement groove 121 when the drive device 11 rotates, thus improving the stability of the take-up shaft 12.
[0053] After placement, the worker attaches the end of the conductive film to the sleeve surface fitted onto the take-up shaft 12, then starts the drive device 11. The drive device 11 rotates, driving the take-up shaft 12 to rotate, and the take-up shaft 12 winds up the conductive film. Initially, the lower end of the adjusting plate 14 above the take-up shaft 12 is in contact with the take-up shaft 12, and the first roller 141 is rotatably connected to the lower end of the adjusting plate 14. When the take-up shaft 12 winds up the conductive film, the conductive film is wound onto the take-up shaft 12, and the diameter of the take-up shaft 12 increases as the conductive film is wound up. Simultaneously, the first roller 141 engages with the conductive film during winding. The take-up end on the reel 12 is squeezed. After the take-up end is squeezed, the first roller 141 squeezes the conductive film. While rolling, the first roller 141 can flatten the wrinkles and bottom wrinkles of the conductive film caused by improper winding, thereby avoiding the problem of wrinkles and bottom wrinkles on the surface of the conductive film after winding to a certain extent. As the take-up reel 12 winds the conductive film, the diameter of the take-up reel 12 gradually increases. The outer side of the conductive film pushes the first roller 141, and the first roller 141 pushes the adjusting plate 14. The adjusting plate 14 is slidably connected to the inside of the first slide groove 13 through a slider, so the adjusting plate 14 will move upward inside the first slide groove 13.
[0054] Since the side of the adjusting plate 14 meshes with the gear 15, when the adjusting plate 14 moves upward, it meshes with the gear 15. The gear 15 then contacts one end of the cutting plate 17. Therefore, when the adjusting plate 14 moves upward inside the first slide groove 13, it meshes with the gear 15, which rotates clockwise. When the gear 15 rotates clockwise, it meshes with the cutting plate 17. The cutting plate 17 is affected by the meshing action of the gear 15, and moves downward through the slider inside the second slide groove 16. During the downward movement of the cutting plate 17, the blade at the lower end of the cutting plate 17 cuts the conductive film. After the conductive film is cut, the operator removes the wound conductive film from the winding shaft 12. Through mechanical cooperation, the cutting blade automatically cuts the conductive film after it is wound, avoiding the need for CNC programming or redundant controllers. Instead, a separate controller controls a separately operating cutting blade to cut the conductive film, thereby ensuring cutting accuracy while reducing the failure rate.
[0055] The handle on the side of the ring plate 123 is rotated counterclockwise. When the handle drives the ring plate 123 to rotate counterclockwise inside the ring groove 122, the end of the ring plate 123 located inside the placement groove 121 no longer obstructs the placement groove 121. Then, the operator manually holds the end of the take-up shaft 12 located inside the placement groove 121. Since the drive device 11 is rotatably connected to the machine body 1, the operator lifts the take-up shaft 12 and rotates it out of the placement groove 121. At this time, the drive device 11 rotates on the machine body 1. Then, the operator takes the completed conductive film off the take-up shaft 12. After taking it off, the conductive film is re-wound, and the above actions are repeated.
[0056] Example 2
[0057] like Figures 1-6 As shown; piston cylinders 142 are provided at both ends of the adjusting plate 14, and piston rods 143 are slidably connected inside the piston cylinders 142; the piston cylinders 142 are fixedly connected inside the first slide groove 13, the piston rods 143 are connected to the slider inside the first slide groove 13, and the air outlet of the piston cylinders 142 is located at the lower end of the adjusting plate 14.
[0058] The air outlet of the piston cylinder 142 is a duckbill-shaped outlet, and the diameter of the end of the air outlet away from the piston cylinder 142 is small.
[0059] The specific workflow is as follows: Piston cylinders 142 are installed at both ends of the adjusting plate 14, and a piston rod 143 is slidably connected inside the piston cylinders 142. Therefore, when the winding shaft 12 winds up the conductive film, the conductive film winds onto the winding shaft 12. The diameter of the winding shaft 12 increases as the conductive film winds up, and the outer side of the conductive film pushes the first roller 141. The first roller 141 pushes the adjusting plate 14. The adjusting plate 14 is slidably connected inside the first slide groove 13 via a slider. Therefore, the adjusting plate 14 moves upward inside the first slide groove 13. The slider inside the first slide groove 13 presses against the piston rod 143 on the piston cylinder 142. The piston rod 143 is pressed against the piston rod. The gas inside the piston cylinder 142 is compressed, and the gas inside the piston cylinder 142 is ejected from the outlet of the piston cylinder 142. By positioning the outlet of the piston cylinder 142 at the lower end of the adjusting plate 14 and designing the outlet of the piston cylinder 142 as a duckbill, the gas ejected from the lower end of the adjusting plate 14 blows the gas onto the upper surface of the conductive film, preventing dust and impurities from remaining on the upper surface of the conductive film. This causes the dust and impurities to be wound into the conductive film cylinder as the winding shaft 12 rotates, thereby improving the cleanliness of the conductive film after winding. Furthermore, by designing the outlet of the piston cylinder 142 as a duckbill, the gas inside the piston cylinder 142 is ejected from the outlet over a wider range, resulting in better cleaning of the upper part of the conductive film.
[0060] Example 3
[0061] like Figures 1-6 As shown; a rectangular groove 171 is provided inside the cutting plate 17, and a limit block 172 is slidably connected inside the rectangular groove 171 by a spring; a top plate 173 is fixedly connected to the machine body 1, and when the cutting plate 17 moves downward, the limit block 172 contacts the top plate 173.
[0062] The top plate 173 is rotatably connected to a second roller 174. When the cutting plate 17 moves downward, the limiting block 172 contacts the second roller 174.
[0063] The outer side of the second roller 174 is uniformly provided with strip grooves 175.
[0064] The specific workflow is as follows;
[0065] A rectangular groove 171 is provided inside the cutting plate 17, and a limit block 172 is slidably connected inside the rectangular groove 171 by a spring. A top plate 173 is fixedly connected to the upper end of the machine body 1. When the conductive film is wound up, the adjusting plate 14 moves upward and meshes with the gear 15. The gear 15 is in contact with one end of the cutting plate 17. Therefore, when the adjusting plate 14 moves upward inside the first slide groove 13, the adjusting plate 14 meshes with the gear 15, and the gear 15 rotates clockwise. When the gear 15 rotates clockwise, it meshes with the cutting plate 17. The cutting plate 17 is subjected to the meshing action of the gear 15. The cutting plate 17 is moved by the slider in the second... As the slide 16 moves downward, the cutting plate 17 moves downward, causing the limiting block 172 to move downward. When the winding shaft 12 is winding the conductive film, the conductive film slides over the top end of the top plate 173. A second roller 174 is provided at the top end of the top plate 173. When the conductive film slides over the top end of the second roller 174, the second roller 174 rotates. By uniformly opening strip grooves 175 on the outer side of the second roller 174, the strip grooves 175 increase the surface roughness of the second roller 174 and increase the friction between the second roller 174 and the conductive film, which to a certain extent prevents the conductive film from shifting during winding.
[0066] Furthermore, when the cutting plate 17 moves downward, the lower blade of the cutting plate 17 will cut the conductive film. Before the cutting blade cuts the conductive film, the limiting block 172 on the cutting plate 17 will first press the upper end of the conductive film. As the cutting plate 17 continues to descend, the limiting block 172 will move upward inside the rectangular groove 171 until the lower blade of the cutting plate 17 cuts the conductive film. When the limiting block 172 presses the conductive film, it prevents the conductive film from shifting during the cutting process.
[0067] Example 4
[0068] like Figures 1-6 As shown; a cleaning plate 18 is provided on the body 1, and a brush plate 19 is provided on the cleaning plate 18. The brush plate 19 is located at the end of the top plate 173 away from the winding shaft 12.
[0069] The specific workflow is as follows: A cleaning plate 18 is provided on the machine body 1, and a brush plate 19 is provided on the cleaning plate 18. The brush plate 19 is located at the end of the top plate 173 away from the winding shaft 12. When the winding shaft 12 rotates, the winding shaft 12 winds up the conductive film. During the process of the conductive film moving towards the winding shaft 12, the lower end face of the conductive film contacts the bristles on the brush plate 19. The bristles clean the lower side of the conductive film, preventing impurities remaining on the conductive film from entering the inside of the wound conductive film cylinder, thereby improving the cleanliness of the conductive film during winding.
[0070] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
