Technical Field
[0001] This invention relates to the field of polyimide film correction device technology, specifically a polyimide film correction device. Background Technology
[0002] Polyimide film is made by polycondensation and casting of pyromellitic dianhydride (PMDA) and diaminodiphenyl ether (ODA) in a strongly polar solvent, followed by imidization. When the polyimide film semi-finished product exits the casting machine drum, the film often shifts left and right, and the width of the film changes irregularly, which makes it difficult to mount the clamping plate, and the clamping width is inconsistent, as is the stretching width.
[0003] Existing film web guiding equipment suffers from film misalignment due to various factors, including uneven traction force, environmental factors such as temperature, humidity, static electricity, and dust. For example, tension issues can cause film misalignment during movement if a section of the film becomes loose or unstretched. Furthermore, existing equipment provides direct tension control without buffering, which can damage or even break the film during tension adjustment, leading to unnecessary problems. Film misalignment also results in uneven film winding, affecting the normal processing and production of polyimide films and causing economic losses. Therefore, this invention designs a polyimide film web guiding device to solve the above problems. Summary of the Invention

[0039] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0040] like Figures 1-16As shown, the polyimide film correction device of the present invention includes a winding mechanism 1, a correction mechanism 2, an adjustment mechanism 3, a buffer mechanism 4, and a pressing mechanism 5. The winding mechanism 1 is provided with the correction mechanism 2 at one end, the correction mechanism 2 is provided with the adjustment mechanism 3 at one end, the adjustment mechanism 3 is provided with the buffer mechanism 4 at one end, and the buffer mechanism 4 is provided with the pressing mechanism 5 at one end. By setting the structure, when the tension of the film body 16 changes, the rotation angle of the first guide roller 219 and the second guide roller 221 around the movable block 213 will be adjusted, thereby adjusting the fit between the first guide roller 219 and the second guide roller 221 and the film body 16 to improve the correction effect of the film body 16. The cylindrical cylinder 46 and the arc plate 411 are used. When the tension of the film body 16 changes, the tension sensor 48 will control the hydraulic cylinder 41 through the controller to move the cylindrical cylinder 46 away from and closer to the film body 16 to adjust the tension. In addition, a second spring 49 is also provided inside the cylindrical cylinder 46 to buffer the tension of the film body 16.
[0041] Preferably, the winding mechanism 1 includes a base 11, a first motor 12 fixedly connected to the upper end of the base 11, a first rotating shaft 13 fixedly connected to one end of the first motor 12, a first support plate 14 rotatably connected to the side wall of the first rotating shaft 13, the lower end of the first support plate 14 fixedly connected to the base 11, a winding roller 15 fixedly connected to the side wall of the first rotating shaft 13, a film body 16 wound around the side wall of the winding roller 15, an unwinding roller 17 wound around one end of the film body 16, a second rotating shaft 18 fixedly connected to the side wall of the unwinding roller 17, a second support plate 19 rotatably connected to the side wall of the second rotating shaft 18, and the lower end of the second support plate 19 fixedly connected to the base 11. The membrane body 16 is fixedly connected to the base 11. First, the first motor 12 is started to rotate. The rotation of the first motor 12 drives the first rotating shaft 13 to rotate, which in turn drives the take-up roller 15 to rotate. The take-up roller 15 then winds up the membrane body 16, causing it to move to one end. This movement of the membrane body 16 then drives the unwind roller 17 to rotate, unwinding the membrane body 16. Thus, the membrane body 16 can be wound up by the rotation of the first motor 12.
[0042] Preferably, the correction mechanism 2 includes a second motor 21, the side wall of which is fixedly connected to the base 11. A third rotating shaft 22 is fixedly connected to one end of the second motor 21. A first bearing 23 is fixedly connected to the side wall of the third rotating shaft 22. The outer side wall of the first bearing 23 is fixedly connected to the base 11. A worm gear 24 is fixedly connected to one end of the side wall of the third rotating shaft 22. A worm wheel 25 meshes with one end of the worm gear 24. A first rotating rod 26 is fixedly connected to the center of the worm wheel 25. The side wall of the first rotating rod 26 is rotatably connected to the base 11. A second bearing 27 is fixedly connected to the side wall of the first rotating rod 26. The lower end of the second bearing 27 is fixedly connected to the base 11. A spur gear 28 is fixedly connected to the side wall of the first rotating rod 26. A rack 29 meshes with one end of the spur gear 28. A sliding plate 210 is fixedly connected to one end of the rack 29. A guide rail 211 is slidably connected to the end of the sliding plate 210. The lower end of the guide rail 211 is fixedly connected to the base 11. A first movable plate 212 is rotatably connected to the upper end of the sliding plate 210. A movable block 213 is rotatably connected to one end of the first movable plate 212. A first rotating shaft 215 is fixedly connected to one end of the movable block 213. A torsion spring 216 is fixedly connected to the side wall of the first rotating shaft 215. One end of the torsion spring 216 is fixedly connected to the movable block 213. A rotating block 214 is fixedly connected to the other end of the torsion spring 216. A second movable plate 217 is fixedly connected to one end of the rotating block 214. A second rotating shaft 218 is rotatably connected to the side wall of the second movable plate 217. A first guide roller 219 is fixedly connected to the side wall of the second rotating shaft 218. A third rotating shaft 220 is rotatably connected to the side wall of the second movable plate 217. A second guide roller 221 is fixedly connected to the side wall of the third rotating shaft 220.When the membrane body 16 deflects, it is detected by the thin-film offset sensor 110. The thin-film offset sensor 110 transmits the detected electrical signal to the controller, which in turn rotates the second motor 21. The rotation of the second motor 21 drives the third rotating shaft 22 to rotate, which in turn drives the worm gear 24 to rotate, which in turn drives the turbine 25 to rotate, which in turn drives the first rotating rod 26 to rotate, which in turn drives the spur gear 28 to rotate, which in turn drives the rack 29 to move to one end. Two racks 29 are meshed at one end of the spur gear 28. When the spur gear 28 rotates, one rack 29 moves forward and the other rack 29 moves backward. The movement of the rack 29 to one end drives the sliding plate 210 to move to one end, which in turn drives the first movable plate 212 to move to one end. The movement of the movable block 213 causes the rotating block 214 to move to one end, which in turn causes the second movable plate 217 to move to one end. This movement of the second movable plate 217 then causes the first guide roller 219 and the second guide roller 221 to move to one end. This offset of the first guide roller 219 and the second guide roller 221 adjusts the offset of the membrane body 16. The membrane body 16 is arranged so that it crosses between the second guide roller 221 and the first guide roller 219, passing under the second guide roller 221 and then around to the top of the first guide roller 219. This ensures close contact between the membrane body 16 and the second guide roller 221 and the first guide roller 219, improving the correction effect. The membrane offset sensor 110 detects the membrane offset and automatically corrects the membrane body 16.
[0043] Preferably, the adjusting mechanism 3 includes a first sliding block 31, the sidewall of which is tightly fitted to the sliding plate 210. A second sliding block 32 is fixedly connected to one end of the first sliding block 31. A first sleeve 33 is slidably connected to one sidewall of the second sliding block 32. A baffle 34 is fixedly connected to one end of the second sliding block 32. A first spring 35 is fixedly connected to one end of the baffle 34. One end of the first spring 35 is fixedly connected to the first sleeve 33. A first connecting block 36 is fixedly connected to the sidewall of the first sliding block 31. One end of the connecting block 36 is fixedly connected to a first inclined slider 37, the upper sidewall of which is tightly fitted to the second rotating shaft 218. When the spur gear 28 rotates, one rack 29 moves forward while the other moves backward. Thus, the rotation of the spur gear 28 always drives the sliding plate 210 to move to one end. When the sliding plate 210 moves to one end, it drives the first sliding block 31 to move to one end. The movement of the first sliding block 31 to one end drives the second sliding block 32 to move to one end, and the movement of the second sliding block 32 to one end drives... When baffle 34 moves to one end, it compresses the first spring 35. When sliding block 31 moves to one end, it drives the first connecting block 36 to move to one end. The movement of the first connecting block 36 to one end drives the first inclined slider 37 to move to one end. The movement of the first inclined slider 37 to one end drives the second rotating shaft 218 to rotate around the movable block 213. The rotation of the second rotating shaft 218 around the movable block 213 drives the first guide roller 219 to rotate around the movable block 213. The rotation of the second rotating shaft 218 around the movable block 213 also drives the second... The movable plate 217 rotates around the movable block 213. The rotation of the second movable plate 217 around the movable block 213 will drive the rotating block 214 to rotate around the movable block 213. The rotation of the rotating block 214 around the movable block 213 will compress the torsion spring 216. Through the structure, when the tension of the membrane body 16 changes, the rotation angle of the first guide roller 219 and the second guide roller 221 around the movable block 213 will be adjusted, thereby adjusting the fit between the first guide roller 219 and the second guide roller 221 and the membrane body 16, thereby improving the effect of correcting the deviation of the membrane body.
[0044] Preferably, the buffer mechanism 4 includes a hydraulic cylinder 41, the lower end of the side wall of the hydraulic cylinder 41 is fixedly connected to the base 11, a second connecting block 42 is fixedly connected to one end of the hydraulic cylinder 41, a first connecting rod 43 is fixedly connected to one end of the second connecting block 42, a second sleeve 44 is slidably connected to the side wall of the first connecting rod 43, the lower end of the second sleeve 44 is fixedly connected to the base 11, a second rotating rod 45 is rotatably connected to the side wall of one end of the first connecting rod 43, a cylinder 46 is fixedly connected to one end of the second rotating rod 45, and a third sleeve 47 is fixedly connected to the inner side wall of the cylinder 46. 7. An internally sliding tension sensor 48 is connected. One end of the tension sensor 48 is fixedly connected to a second spring 49, and one end of the second spring 49 is fixedly connected to the cylinder 46. One end of the tension sensor 48 is fixedly connected to a sliding rod 410, and one end of the sliding rod 410 is fixedly connected to an arc-shaped plate 411. At this time, the hydraulic cylinder 41 is activated and moves to one end. The movement of the hydraulic cylinder 41 to one end will drive the second connecting block 42 to one end. The movement of the second connecting block 42 to one end will drive the first connecting rod 43 to one end. The movement of the first connecting rod 43 to one end will drive the second rotating rod 45 to one end. Moving rod 45 to one end will cause cylinder 46 to move to one end. Moving cylinder 46 to one end will cause sliding rod 410 to move to one end. Moving sliding rod 410 to one end will cause arc plate 411 to move to one end. Moving arc plate 411 to one end will press the membrane body 16 to make it taut. Moving arc plate 411 to one end and pressing the membrane body 16 will cause sliding rod 410 to slide into cylinder 46. Sliding sliding rod 410 into cylinder 46 will cause tension sensor 48 to slide into third sleeve 47 and compress second spring 49. When the tension of membrane body 16 changes, tension sensor 48 will be controlled by the controller. The tension is adjusted by a hydraulic cylinder 41. A second spring 49 is also installed inside the cylinder 46 to buffer the tension and prevent the membrane body 16 from being stretched too tight, thus avoiding damage. The tension sensor 48, through the controller, moves the cylinder 46 closer to or away from the membrane body 16 as the tension of the membrane body 16 changes. The second spring 49 inside the cylinder 46 further buffers the tension and prevents the membrane body 16 from being stretched too tight, thus avoiding damage.
[0045] Preferably, the pressing mechanism 5 includes a second connecting rod 51, one end of which is fixedly connected to a first connecting rod 43. A second inclined slider 52 is fixedly connected to the upper end of the second connecting rod 51. A third rotating rod 53 is attached to one end of the second inclined slider 52. A first pressure roller 54 is fixedly connected to one end of the third rotating rod 53. A third sliding block 55 is rotatably connected to the side wall of the third rotating rod 53. A slide rail 56 is slidably connected to the side wall of the third sliding block 55. The lower end of the slide rail 56 is fixedly connected to the base 11. A third spring 57 is fixedly connected to the upper end of the third sliding block 55. A fixing block 58 is fixedly connected to the upper end of the third spring 57. The side wall of the fixing block 58 is fixedly connected to the slide rail 56. A fourth rotating rod 59 is rotatably connected to the inner side wall of the fixing block 58. A second pressure roller 510 is rotatably connected to one end of the fourth rotating rod 59. When the first connecting rod 43 moves to one end, it will drive the second connecting rod 510. When rod 51 moves to one end, the second connecting rod 51 moves to one end, which in turn drives the second inclined slider 52 to move to one end. The second inclined slider 52 moves to one end, which in turn drives the third rotating rod 53 to move upward. The upward movement of the third rotating rod 53 drives the first pressure roller 54 to move upward. The upward movement of the third rotating rod 53 drives the third sliding block 55 to move upward. The upward movement of the third sliding block 55 compresses the third spring 57. When the first pressure roller 54 moves upward, it will bring the middle membrane body 16 into contact with the second pressure roller 510, thereby tightening one end of the membrane body 16. The tension sensor 48, which is set in the cylinder 46 and the arc plate 411, will adjust the tension by controlling the hydraulic cylinder 41 through the controller when the tension of the membrane body 16 changes. In addition, a second spring 49 is also set inside the cylinder 46 to buffer the tension of the membrane body 16, so as to avoid the membrane body 16 being too tight and thus damaged.
[0046] Working principle: In use, the invention first activates the first motor 12, which drives the first rotating shaft 13 to rotate. The rotating shaft 13 then drives the take-up roller 15 to rotate, which in turn winds up the film body 16. This movement of the take-up roller 15 moves the film body 16 to one end, which in turn drives the unwind roller 17 to rotate, unwinding the film body 16. Thus, the rotation of the first motor 12 enables the film body 16 to be wound up.
[0047] When the membrane body 16 deflects, it is detected by the thin-film offset sensor 110. The thin-film offset sensor 110 transmits the detected electrical signal to the controller, which in turn rotates the second motor 21. The rotation of the second motor 21 drives the third rotating shaft 22 to rotate, which in turn drives the worm gear 24 to rotate, which in turn drives the turbine 25 to rotate, which in turn drives the first rotating rod 26 to rotate, which in turn drives the spur gear 28 to rotate, which in turn drives the rack 29 to move to one end. Two racks 29 are meshed at one end of the spur gear 28. When the spur gear 28 rotates, one rack 29 moves forward and the other rack 29 moves backward. The movement of the rack 29 to one end drives the sliding plate 210 to move to one end, which in turn drives the first movable plate 212 to move to one end. The movement of the movable block 213 will cause the movable block 213 to move to one end, which in turn will cause the rotating block 214 to move to one end. The movement of the rotating block 214 to one end will cause the second movable plate 217 to move to one end, which in turn will cause the first guide roller 219 and the second guide roller 221 to move to one end. In this way, the offset of the first guide roller 219 and the second guide roller 221 will adjust the offset of the membrane body 16. By adopting the set structure, the membrane body 16 crosses between the second guide roller 221 and the first guide roller 219. The membrane body 16 is lower at the second guide roller 221 and then wraps around to the upper at the first guide roller 219, so that the membrane body 16 can be in close contact with the second guide roller 221 and the first guide roller 219, thereby improving the effect of correcting the membrane body 16. The membrane offset sensor 110 can detect the membrane offset and automatically correct the membrane body 16.
[0048] When the spur gear 28 rotates, one rack 29 moves forward while the other moves backward. This rotation of the spur gear 28 continuously drives the sliding plate 210 to move to one end. As the sliding plate 210 moves to one end, it drives the first sliding block 31 to move to one end. The movement of the first sliding block 31 to one end drives the second sliding block 32 to move to one end. The movement of the second sliding block 32 to one end drives the baffle 34 to move to one end. The movement of the baffle 34 to one end compresses the first spring 35. The movement of the first sliding block 31 to one end drives the first connecting block 36 to move to one end. The movement of the first connecting block 36 to one end drives the first inclined slider 37 to move to one end. The movement of the first inclined slider 37 to one end drives the second rotating shaft 218 to rotate around the movable block 21. 3. Rotation: The rotation of the second rotating shaft 218 around the movable block 213 will drive the first guide roller 219 to rotate around the movable block 213. The rotation of the second rotating shaft 218 around the movable block 213 will also drive the second movable plate 217 to rotate around the movable block 213. The rotation of the second movable plate 217 around the movable block 213 will drive the rotating block 214 to rotate around the movable block 213. The rotation of the rotating block 214 around the movable block 213 will compress the torsion spring 216. Through the structure, when the tension of the membrane body 16 changes, the rotation angle of the first guide roller 219 and the second guide roller 221 around the movable block 213 will be adjusted, thereby adjusting the fit between the first guide roller 219 and the second guide roller 221 and the membrane body 16, thereby improving the effect of correcting the deviation of the membrane body.
[0049] At this time, the hydraulic cylinder 41 is activated and moves to one end. This movement of the hydraulic cylinder 41 causes the second connecting block 42 to move to one end, which in turn causes the first connecting rod 43 to move to one end. The first connecting rod 43 then causes the second rotating rod 45 to move to one end, which in turn causes the cylinder 46 to move to one end. The cylinder 46 then causes the sliding rod 410 to move to one end, which in turn causes the arc-shaped plate 411 to move to one end. The arc-shaped plate 411 presses the membrane body 16 to tighten it. This pressing of the arc-shaped plate 411 also causes the sliding rod 410 to slide into the cylinder 46. The sliding rod 410's movement into the cylinder 46 activates the tension sensor. The device 48 slides into the third sleeve 47 and compresses the second spring 49. When the tension of the membrane body 16 changes, the tension sensor 48 controls the hydraulic cylinder 41 through the controller to adjust the tension. At the same time, the second spring 49 is also provided inside the cylinder 46 to buffer the tension and prevent the membrane body 16 from being stretched too tight, which could damage the membrane body 16. The device uses the cylinder 46 and the arc plate 411 to adjust the tension of the membrane body 16. When the tension of the membrane body 16 changes, the tension sensor 48 controls the hydraulic cylinder 41 through the controller to move the cylinder 46 away from and closer to the membrane body 16 to adjust the tension. The second spring 49 is also provided inside the cylinder 46 to buffer the tension and prevent the membrane body 16 from being stretched too tight, which could damage the membrane body 16.
[0050] As the first connecting rod 43 moves to one end, it drives the second connecting rod 51 to move to one end. The movement of the second connecting rod 51 to one end drives the second inclined slider 52 to move to one end. The movement of the second inclined slider 52 to one end drives the third rotating rod 53 to move upward. The upward movement of the third rotating rod 53 drives the first pressure roller 54 to move upward. The upward movement of the third rotating rod 53 drives the third sliding block 55 to move upward. The upward movement of the third sliding block 55 compresses the third spring 57. When the first pressure roller 54 moves upward, it will bring the middle membrane body 16 into contact with the second pressure roller 510, thereby tightening one end of the membrane body 16. The tension sensor 48, which is set in the cylinder 46 and the arc plate 411, will adjust the tension by controlling the hydraulic cylinder 41 through the controller when the tension of the membrane body 16 changes. In addition, a second spring 49 is also set inside the cylinder 46 to buffer the tension of the membrane body 16, so as to avoid the membrane body 16 being too tight and thus damaged.
