Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figure 1-7A rapid curing device for a polyimide film insulation layer includes a transport box 1. Rotatable second longitudinal driven rollers 6 are provided at both ends inside the transport box 1. A rotatable first longitudinal driven roller 5 is provided inside the transport box 1 and at the top of the second longitudinal driven rollers 6. Movable circular moving rollers 7 are provided on both sides of the first longitudinal driven roller 5. A moving mechanism for moving the two circular moving rollers 7 is provided inside the transport box 1.
[0025] The top and bottom of the transport box 1 are equipped with liftable drying boxes 2. The inside of the drying box 2 is equipped with electric heating wires 20. The top of the drying box 2 is bolted with a blower 4. The output end of the blower 4 is connected to the drying box 2. The outside of the transport box 1 is equipped with a lifting mechanism for lifting the drying box 2.
[0026] The moving mechanism includes a drive motor 3, which is bolted to the outside of the transport box 1. A first transverse threaded rod 10 is fixed to the output end of the drive motor 3. A second transverse threaded rod 11 is fixed to the end of the first transverse threaded rod 10 away from the drive motor 3. The threads of the first transverse threaded rod 10 and the second transverse threaded rod 11 are opposite in direction. A vertical sliding plate 8 is threaded to the outside of both the first transverse threaded rod 10 and the second transverse threaded rod 11. A circular connecting pipe 9 is rotatably connected to the bottom of the vertical sliding plate 8 through a bearing. The circular connecting pipe 9 is close to the side of the circular moving roller 7 and is fixedly connected to the circular moving roller 7.
[0027] The circular moving roller 7 has multiple rectangular guide blocks fixed inside, and the first longitudinal driven roller 5 has multiple rectangular guide grooves that are adapted to the rectangular guide blocks inside. The circular moving roller 7 and the first longitudinal driven roller 5 are slidably connected through the rectangular guide blocks and rectangular guide grooves. Through the setting of the rectangular guide blocks and rectangular guide grooves, the circular moving roller 7 can slide laterally on the outside of the first longitudinal driven roller 5, and the rotation of the first longitudinal driven roller 5 can drive the circular moving roller 7 to rotate.
[0028] The connection between the first transverse threaded rod 10 and the second transverse threaded rod 11 is rotatably connected to a partition plate via a bearing. The top of the partition plate is fixedly connected to the transport box 1, thereby making the connection between the first transverse threaded rod 10 and the second transverse threaded rod 11 more stable, preventing the connection between the first transverse threaded rod 10 and the second transverse threaded rod 11 from bending, and enabling the first transverse threaded rod 10 and the second transverse threaded rod 11 to rotate synchronously better.
[0029] A transverse smooth rod 12 is provided inside the transport box 1 and at the top of the first transverse threaded rod 10. The transverse smooth rod 12 is located inside the transport box 1 and is fixedly connected to the transport box 1. The transverse smooth rod 12 passes through the interior of the vertical sliding plate 8 and is slidably connected to the vertical sliding plate 8, so that the vertical sliding plate 8 can slide laterally on the outside of the transverse smooth rod 12.
[0030] Here, the operation of the drive motor 3 enables the first transverse threaded rod 10 and the second transverse threaded rod 11 to rotate. The rotation of the first transverse threaded rod 10 and the second transverse threaded rod 11 enables the vertical sliding plate 8 to slide laterally on the outside of the transverse smooth rod 12. The movement of the vertical sliding plate 8, through the circular connecting tube 9, enables the circular moving roller 7 to move on the outside of the first longitudinal driven roller 5, thereby making the movement directions of the two circular moving rollers 7 opposite. Through the movement between the two circular moving rollers 7, the film can be prevented from bending and wrinkling during the curing process, thus reducing the curing effect.
[0031] The lifting mechanism includes a hydraulic cylinder 13, which is fixed to the outside of the transport box 1. A rectangular sliding block 14 is fixed to the output end of the hydraulic cylinder 13. The top and bottom of the rectangular sliding block 14 are rotatably connected to an inclined rotating column 15 via a pin. An arc-shaped fixing block 16 is also provided on the outside of the transport box 1 and at one end of the rectangular sliding block 14. A vertical light rod 17 is fixed to the top and bottom of the arc-shaped fixing block 16. A vertical sliding tube 18 is slidably connected to the outside of the vertical light rod 17. The inclined rotating column 15 and the vertical sliding tube 18 are rotatably connected via a pin. An arc-shaped connecting plate 19 is fixed to the end of the vertical sliding tube 18 away from the arc-shaped fixing block 16. The arc-shaped connecting plate 19 is close to the side of the drying box 2 and is fixedly connected to the drying box 2.
[0032] Here, the operation of the oblique rotating column 15 allows the rectangular sliding block 14 to move. The movement of the rectangular sliding block 14, through the oblique rotating column 15, allows the vertical sliding tube 18 to slide vertically on the outside of the vertical light rod 17. The sliding of the vertical sliding tube 18 allows the arc-shaped connecting plate 19 to move. The movement of the arc-shaped connecting plate 19 allows the drying chamber 2 to move inside the transport box 1, thereby adjusting the distance between the drying chamber 2 and the film, and further adjusting the distance between the drying chamber 2 and the electric heating wire 20. This allows the device to adjust the lifting and lowering of the drying chamber 2 according to the film curing requirements.
[0033] By setting two movable circular rollers 7 at both ends of the film, the film can be smoothed in real time during the curing process, ensuring that the film remains flat when heated, avoiding bending and wrinkling problems caused by uneven tension, improving the surface quality of the film, and ensuring the stability of its insulation performance.
[0034] By setting up a height-adjustable drying chamber 2, the distance between the drying chamber 2 and the film can be flexibly adjusted according to the film thickness, curing requirements and heating temperature. This not only improves heating efficiency but also avoids the problem of local overheating or underheating of the film, ensuring that the film is heated evenly during the curing process and further improving the film's performance.
[0035] Working principle: The operation of the drive motor 3 enables the first transverse threaded rod 10 and the second transverse threaded rod 11 to rotate. The rotation of the first transverse threaded rod 10 and the second transverse threaded rod 11 enables the vertical sliding plate 8 to slide laterally outside the transverse smooth rod 12. The movement of the vertical sliding plate 8, through the circular connecting tube 9, enables the circular moving roller 7 to move outside the first longitudinal driven roller 5, thereby making the movement directions of the two circular moving rollers 7 opposite. Through the movement between the two circular moving rollers 7, the film can be prevented from bending and wrinkling during the curing process, thus reducing the curing effect.
[0036] The operation of the oblique rotating column 15 allows the rectangular sliding block 14 to move. The movement of the rectangular sliding block 14, through the oblique rotating column 15, allows the vertical sliding tube 18 to slide vertically on the outside of the vertical light rod 17. The sliding of the vertical sliding tube 18 allows the arc-shaped connecting plate 19 to move. The movement of the arc-shaped connecting plate 19 allows the drying chamber 2 to move inside the transport box 1, thereby adjusting the distance between the drying chamber 2 and the film, and further adjusting the distance between the drying chamber 2 and the electric heating wire 20. This allows the device to adjust the lifting and lowering of the drying chamber 2 according to the film curing requirements.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
