Polyimide has excellent thermal stability, chemical corrosion resistance and mechanical properties. It is usually orange-yellow. The flexural strength of polyimide reinforced with graphite or glass fiber can reach 345 MPa, and the flexural modulus reaches 20 GPa.

Detailed implementation manners
[0026] In the existing drying device, polyimide film is usually directly placed into the drying device for drying treatment. However, this treatment method causes the surface of the polyimide film to be wrinkled during the production process, resulting in uneven drying during the drying process. As a result, the quality of the polyimide film in subsequent use is reduced. At this time, not only does it cause the user to manually iron the surface of the polyimide film with an external ironing tool in advance, which is time-consuming and laborious, but also increases the user's workload, reduces the working efficiency of drying the polyimide film, and is not convenient for use. Therefore, through research, the inventor provides a polyimide film winding and drying device. By the combined use of a drying component and an ironing component, the purpose of ironing and flattening the surface wrinkles of the polyimide film in advance while drying the polyimide film is achieved, thereby improving the uniformity of the polyimide film during drying, avoiding the situation of uneven drying due to wrinkles during drying of the polyimide film, enhancing the working efficiency of drying the polyimide film, saving time and effort, reducing the user's workload, improving the use quality of the polyimide film, and being convenient for use, thus solving the above defects.

[0030] Specifically, the user first sleevs the external polyimide film and the take-up reel on the surface of the collecting rod 42. When it is necessary to take out the object to be dried before or after sleeving or after drying, the user can manually disassemble and assemble the fixing plate 41 on the right side, so that the user can manually take out or install the polyimide film. When winding is required, the user can sleeve the polyimide film on the front collecting rod 42, and then manually or with the help of an external clamping tool, pull one side of the polyimide film through the through cavity 2 and place it on the surface of the rear collecting rod 42, and then perform a winding process. At this time, start the first motor 43, the first motor 43 drives the collecting rod 42 to rotate, and the collecting rod 42 drives the polyimide film wound on its surface to rotate, so as to achieve the purpose of collection, and at the same time of winding, start the drying component 5 and the ironing component 6 to dry and flatten the wrinkles on its surface;

There is a space between the opposite sides of the two drying members 512, which can be adjusted according to the actual processing conditions, such as according to the thickness of the polyimide film, so as to perform drying processing on both sides of the polyimide film at the same time;
[0033] Specifically, when it is necessary to dry the imide film, the second motor 54 can be started. The output shaft of the second motor 54 drives the rotating disk 56 to rotate. The rotating disk 56 drives the push rod 57 to rotate. While the push rod 57 rotates, it pushes the left and right sides of the push frame 58 to swing. While the push frame 58 moves, it pushes the sliding rod 510 to move. While the sliding rod 510 moves, it pushes the moving plate 59 to move to the left and right sides. While the moving plate 59 moves, it drives the ironing assembly 6 to move simultaneously. The moving plate 59 drives the connecting rod 511 to move synchronously. The connecting rod 511 drives the drying member 512 to move synchronously, and the drying member 512 is started during the movement to uniformly dry both sides of the imide film, which is convenient for use;
[0034] Please refer to Figures 1 to 7 , an ironing assembly 6 is arranged in the inner cavity of the installation box 51. The ironing assembly 6 includes a first toothed plate 61. The outer surface of the first toothed plate 61 is slidably connected to the installation box 51. A fixed frame is connected to the rear side of the left side of the first toothed plate 61. The rear side of the fixed frame is connected to the moving plate 59. Both the left and right sides of the front side of the drying box 1 are connected with protection boxes 612. The bottom of the inner cavity of the protection box 612 is rotatably connected with an operating rod 62. The top of the operating rod 62 penetrates into the inner cavity of the installation box 51 and is rotatably connected to the top of the inner cavity of the installation box 51. A first gear 63 meshing with the first toothed plate 61 is connected to the surface of the operating rod 62. A positioning rod 64 is rotatably connected to the rear side of the inner cavity of the protection box 612. Two meshing bevel gear parts 65 are respectively connected to the surfaces of the positioning rod 64 and the operating rod 62. A moving rod 66 is rotatably connected to the front side of the inner cavity of the protection box 612. Two belt pulleys 67 are respectively connected to the surfaces of the moving rod 66 and the positioning rod 64, and the two belt pulleys 67 are connected by a belt. A second gear 68 is connected to the surface of the moving rod 66. A second toothed plate 69 meshing with the second gear 68 is slidably connected to the bottom of the inner cavity of the protection box 612;
[0035] Please refer to Figures 2 to 8 , telescopic rods 610 are connected to both the front and rear sides of the second toothed plate 69. The output ends of the telescopic rods 610 are connected with meshing plates 611 meshing with the second gear 68. A fixed frame 613 is connected to the top of the installation frame 3, and the top of the fixed frame 613 is connected to the protection box 612. An ironing part 614 is connected to the outer surface of the second toothed plate 69, and the side of the ironing part 614 away from the second toothed plate 69 is slidably connected to the protection box 612. The ironing part 614 is jointly composed of a positioning plate and an ironing device. The outer surface of the positioning plate is connected to the second toothed plate 69, and a through groove body adapted to the positioning plate is opened in the protection box 612. The ironing part 614 is used in cooperation with the winding assembly 4, and the height position of the ironing part 614 can be adjusted according to the imide film on the winding assembly 4, so as to facilitate ironing and flattening the wrinkles on the surface of the imide film and further facilitate the drying work of the imide film;
[0036] Specifically, while the moving plate 59 moves, it drives the first toothed plate 61 to move synchronously. While the first toothed plate 61 moves, it meshes with and rotates the first gear 63. The first gear 63 drives the operating rod 62 to rotate. The operating rod 62 drives the bevel gear part 65 to mesh and rotate. The bevel gear part 65 drives the positioning rod 64 to rotate. The positioning rod 64 drives the pulley 67 to rotate. The pulley 67 drives the moving rod 66 to rotate. The moving rod 66 drives the second gear 68 to rotate. While the second gear 68 rotates, it meshes with the second toothed plate 69, thereby pushing the second toothed plate 69 to move towards the front and rear sides. When it moves to the meshing plate 611 meshing with the second gear 68, at this time, the second gear 68 rotates clockwise. However, because the meshing plate 611 meshes with the second gear 68, the second gear 68 pushes the meshing plate 611 to move backward, and while moving, it drives the telescopic end of the telescopic rod 610 to move back and forth, so as to facilitate the situation where the second gear 68 rotates in the same direction for a long time and impacts and damages the second toothed plate 69. On the contrary, by using the second gear 68 to rotate counterclockwise, the second gear 68 pulls the meshing plate 611 to move forward, so as to pull the second toothed plate 69 closer to the second gear 68, so as to achieve the working purpose of pushing the second toothed plate 69 to move forward, and the second toothed plate 69 drives the ironing component 614 to evenly iron the wrinkles on both sides of the polyimide film. It should be noted that during the movement, the ironing component 614 is started.
[0037] In summary, the working principle of a polyimide film winding and drying device according to an embodiment of the present invention: The user first puts the polyimide film to be dried into the winding assembly 4, then pulls one side of the polyimide film into the winding assembly 4 on the other side, and then starts the winding assembly 4 to wind the polyimide film. During the winding process, the drying assembly 5 is started to dry both sides of the polyimide film. During this drying process, the drying assembly 5 simultaneously drives the ironing assembly 6 to flatten the wrinkles on both sides of the polyimide film, so as to avoid the situation of uneven drying of the polyimide film during the drying process by the drying assembly 5, which is convenient for use.
[0038] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
