Description

Technical Field

[0001] This invention belongs to the field of polyimide film processing technology, specifically relating to a novel insulating polyimide film winding mechanism. Background Technology

[0002] In the production process of insulating polyimide film, winding is a crucial step, and the performance of the winding mechanism directly affects the winding quality and production efficiency of the film.

[0003] However, existing insulating polyimide film winding mechanisms have many drawbacks. Firstly, the support plate spacing of traditional winding mechanisms is fixed, making it impossible to flexibly adjust according to different specifications of the winding rollers. This results in one winding mechanism often only being compatible with one type of winding roller. To meet different production needs, companies have to equip themselves with multiple corresponding winding mechanisms, which not only significantly increases equipment investment costs but also occupies a large amount of production space, reducing the utilization rate of the production site and resulting in poor practicality and economy. Secondly, the position and height of the adjusting rollers in existing winding mechanisms are mostly fixed, unable to be flexibly adjusted according to the actual needs of the winding process. This makes it difficult to achieve good coordination with the winding rollers, easily leading to problems such as film deviation and wrinkles during winding, affecting winding quality and resulting in poor stability and adaptability of the winding process. Based on the above problems, this application proposes a novel insulating polyimide film winding mechanism to improve these issues. Utility Model Content

[0004] The purpose of this invention is to provide a novel insulating polyimide film winding mechanism that enables synchronous adjustment of the support plate spacing through the coordinated action of a first motor, gears, and a first threaded rod. This allows the winding mechanism to stably adapt to various specifications of winding rollers without requiring separate equipment for different winding rollers, significantly improving the practicality and economy of the mechanism in film winding operations.

[0005] The specific technical solution adopted in this utility model is as follows:

[0006] A novel insulating polyimide film winding mechanism includes a base plate, with fixing blocks fixed on both sides of the upper end of the base plate. A first motor is fixed to the upper end of the base plate and on one side of the two fixing blocks. A first gear is fixed to the output end of the first motor. A second gear is provided on the side of the first gear near the fixing blocks, and the first gear and the second gear are meshed together. A first threaded rod is rotatably connected between the two fixing blocks, and the first threaded rod and the second gear are fixedly connected. Two external threads are provided on the outer side of the first threaded rod. A movable plate is threaded to the outer side of the first threaded rod. A support plate is fixed to the upper end of the two movable plates. A load-bearing plate is fixed to one side of one of the support plates. A second motor is fixed to the upper end of the load-bearing plate. A winding roller is rotatably connected between the two support plates, and the output end of the second motor is fixedly connected to one side of the winding roller.

[0007] In a preferred embodiment, the two external threads have opposite directions of rotation.

[0008] In a preferred embodiment, the fixed block has a movable groove inside, and the movable plate is adapted to the movable groove.

[0009] In a preferred embodiment, two third motors are fixed at the upper end of the base plate, and the output ends of the two third motors are fixed with second threaded rods. A mounting base is fixed at the upper end of the base plate, near the end of the third motors close to the fixing block. The second threaded rods extend into the interior of the mounting base and are rotatably connected to the mounting base. Sliding plates are threadedly connected to the outer sides of the two second threaded rods, inside the mounting bases. An adjusting plate is fixed at the upper end of each of the two sliding plates. A movable plate is provided inside each of the two adjusting plates, and an adjusting roller is rotatably connected between the two movable plates.

[0010] In a preferred embodiment, a fourth motor is provided at the upper end of each of the two adjusting plates, the output end of the fourth motor extends into the interior of the adjusting plate, a third threaded rod is fixed at the lower end of the fourth motor, and the movable plate and the third threaded rod are threadedly connected. Limiting grooves are provided at both ends inside the adjusting plate, and the movable plate and the limiting grooves are adapted to each other.

[0011] In a preferred embodiment, side plates are fixed on both sides of the upper end of the base plate, and the two side plates are located at the end of the mounting base away from the fixing block. An auxiliary roller is rotatably connected between the two side plates.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model uses a first motor to drive a gear and a first threaded rod to enable the moving plate to synchronously adjust the spacing of the support plate. At the same time, the output end of the second motor is detachably connected to the take-up roller, which enables stable installation and convenient replacement of take-up rollers of different specifications. There is no need to equip each take-up roller with a corresponding mechanism, thereby reducing equipment investment costs and production space occupation.

[0014] This utility model uses a third motor to drive a second threaded rod, which in turn moves a sliding plate and an adjusting plate. At the same time, a fourth motor, in conjunction with the third threaded rod, moves a movable plate along a limiting groove within the adjusting plate. This allows for flexible adjustment of the position and height of the adjusting roller, enabling better coordination with the take-up roller for film winding and improving the stability and adaptability of the winding process.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0023] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0024] Please see the appendix Figure 1 and Figure 2 As shown, this utility model provides a novel insulating polyimide film winding mechanism, including a base plate 10. Fixing blocks 11 are fixed to both sides of the upper end of the base plate 10. A first motor 12 is fixed to the upper end of the base plate 10 and to one side of the two fixing blocks 11. A first gear 13 is fixed to the output end of the first motor 12. A second gear 14 is provided on the side of the first gear 13 near the fixing blocks 11, and the first gear 13 and the second gear 14 are meshed together. A first threaded rod 15 is rotatably connected between the two fixing blocks 11, and the first threaded rod 15 and the second gear 14 are fixedly connected. Two external threads are provided on the outer side of the first threaded rod 15. A movable plate 16 is threadedly connected to the outer side of the first threaded rod 15. A support plate 17 is fixed to the upper end of each of the two movable plates 16. A load-bearing plate 18 is fixed to one side of one support plate 17. A second motor 19 is fixed to the upper end of the load-bearing plate 18. A winding roller 20 is rotatably connected between the two support plates 17, and the output end of the second motor 19 is fixedly connected to one side of the winding roller 20.

[0025] In this embodiment, the winding roller 20 between the two support plates 17 is driven to rotate by the second motor 19 to achieve the winding of the film. When it is necessary to replace the take-up roller 20 with one of different lengths or diameters, the first motor 12 drives the first gear 13 to rotate. The rotation of the first gear 13 drives the second gear 14, which meshes with it. The second gear 14 drives the first threaded rod 15 to rotate. The two external threads on the outer side of the first threaded rod 15 cause the two moving plates 16 to move synchronously with the support plate 17 to adjust the spacing. After adjusting the appropriate spacing, the take-up roller 20 is installed. The support plate 17 can precisely adjust the spacing through synchronous movement, ensuring that the two ends of the newly replaced take-up roller 20 can be stably mounted on the support plate 17. In addition, the output end of the second motor 19 and one side of the take-up roller 20 are detachably fixedly connected, for example by bolt fastening or snap-fit ​​connection. When replacing the take-up roller 20, the connection part can be disassembled to quickly remove the old take-up roller 20, replace it with the new take-up roller 20, and then re-fix it. The operation is convenient and there is no need to equip the take-up roller 20 with a corresponding take-up mechanism for different specifications, which greatly reduces the investment cost of the equipment and also reduces the production space occupied by multiple pieces of equipment. It should be noted that the first motor 12, the second motor 19, the third motor 25 and the fourth motor 32 are all electrically connected to an external power supply via wires. The two third motors 25 are started and stopped simultaneously by the controller, and the two fourth motors 32 are also started and stopped simultaneously by the controller. The specific working method will not be described in detail.

[0026] In a preferred embodiment, please refer to Figure 2 The two external threads rotate in opposite directions.

[0027] In this embodiment, the two external threads on the outer side of the first threaded rod 15 have opposite directions of rotation. The rotation of the first threaded rod 15 will drive the two moving plates 16 to move in opposite directions, thereby driving the support plate 17 to move in the opposite direction synchronously to adjust the spacing.

[0028] Secondly, please refer to it again. Figure 2 The fixed block 11 has a movable groove 21 inside, and the movable plate 16 is adapted to the movable groove 21.

[0029] In this embodiment, the moving groove 21 provides precise guidance for the moving plate 16, which can limit the moving trajectory of the moving plate 16 and prevent it from shifting laterally or shaking during reverse movement.

[0030] Secondly, please refer to the following as well. Figure 1 and Figure 3Two third motors 25 are fixed at the upper end of the base plate 10. The output ends of the two third motors 25 are fixed with second threaded rods 26. Mounting seats 27 are fixed at the upper end of the base plate 10 and at the end of the third motors 25 near the fixing block 11. The second threaded rods 26 extend into the interior of the mounting seats 27 and are rotatably connected to the mounting seats 27. Sliding plates 28 are threadedly connected to the outer sides of the two second threaded rods 26 and inside the mounting seats 27. Adjusting plates 29 are fixed at the upper ends of the two sliding plates 28. Movable plates 30 are provided inside the two adjusting plates 29. Adjusting rollers 31 are rotatably connected between the two movable plates 30.

[0031] In this embodiment, two third motors 25 at the upper end of the base plate 10 are activated, and their output ends drive the second threaded rod 26 to rotate. Since the second threaded rod 26 is rotatably connected to the mounting base 27, and the sliding plate 28 with the outer thread connection is located inside the mounting base 27, the sliding plate 28 will drive the adjusting plate 29 to move. The movable plate 30 inside the adjusting plate 29 will then adjust its position, thereby changing the position of the adjusting roller 31 between the two movable plates 30. Driven by the third motors 25, the horizontal position of the adjusting roller 31 can be adjusted, reducing wrinkles caused by slack.

[0032] To further understand and explain, Figure 3 For example, a fourth motor 32 is provided at the upper end of each of the two adjusting plates 29. The output end of the fourth motor 32 extends into the interior of the adjusting plate 29. A third threaded rod 33 is fixed at the lower end of the fourth motor 32. The movable plate 30 and the third threaded rod 33 are threadedly connected. Limiting grooves 34 are provided at both ends inside the adjusting plate 29. The movable plate 30 and the limiting grooves 34 are compatible.

[0033] In this embodiment, the fourth motor 32 at the upper end of the two adjusting plates 29 is activated, and its output end extends into the interior of the adjusting plates 29, driving the third threaded rod 33 to rotate. Since the movable plate 30 is threadedly connected to the third threaded rod 33, and the limiting grooves 34 at both ends of the movable plate 30 and the adjusting plate 29 are compatible, the movable plate 30 will move stably along the limiting grooves 34, thereby adjusting the position of the adjusting roller 31 between the two movable plates 30. For extremely thin films, adjusting the position of the adjusting roller 31 between the two movable plates 30 can bring the adjusting roller 31 closer to the winding roller 20, enhancing the support for the film, reducing tensile deformation during winding, and lowering the film breakage rate. For thicker films, adjusting the adjusting roller 31 to a suitable height can provide sufficient space for the film to stretch, avoid creases caused by compression, and improve the yield rate.

[0034] In a preferred embodiment, please refer to Figure 1Both sides of the upper end of the base plate 10 are fixed with side plates 35. The two side plates 35 are located at the end of the mounting base 27 away from the fixing block 11. An auxiliary roller 36 is rotatably connected between the two side plates 35.

[0035] In this embodiment, the side plates 35 on both sides of the upper end of the base plate 10 and located at the end of the mounting base 27 away from the fixing block 11 can support the auxiliary roller 36. The auxiliary roller 36 between the two side plates 35 can rotate with the movement of the film, providing guidance and support for the film before it enters the adjusting roller 31 and the winding roller 20.

[0036] The working principle of this utility is as follows:

[0037] During operation, the film is first guided and supported by the auxiliary rollers 36 supported by the side plates 35 on both sides of the upper end of the base plate 10, and then enters the adjusting roller 31. The third motor 25 drives the second threaded rod 26 to rotate, causing the sliding plate 28 to move the adjusting plate 29. At the same time, the fourth motor 32 drives the third threaded rod 33 to rotate, causing the movable plate 30 to move along the limiting groove 34, together adjusting the position of the adjusting roller 31 to fit the film. Then the film reaches the take-up roller 20, and the second motor 19 drives the take-up roller 20 to rotate to achieve winding. When changing to a different specification of take-up roller 20, the first motor 12 drives the first gear 13 to rotate, driving the meshing second gear 14 and the first threaded rod 15 to rotate. Since the two external threads on the outer side of the first threaded rod 15 rotate in opposite directions, and the movable plate 16 is adapted to the movable groove 21 of the fixed block 11, the movable plate 16 drives the support plate 17 to move synchronously in the opposite direction to adjust the spacing. Then, the take-up roller 20 is replaced and fixed by detachable connection, and the winding operation can continue.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
