[0002] Polyimide refers to a class of polymers containing an imide ring on the main chain, among which polymers containing a phthalimide structure are the most important. As a special engineering material, polyimide has been widely used in aviation, aerospace, microelectronics, nanotechnology, liquid crystal, separation membranes, lasers and other fields. When in use, the existing unwinding equipment for polyimide film production mostly adopts the method of directly clamping the outer peripheral side of the wound film and moving it on the winding shaft to separate the wound polyimide film from the winding shaft. However, when separating the polyimide film from the winding shaft, this structure requires a fixed support plate at one end of the winding shaft to be separated, which makes it very easy to cause damage to the winding shaft if the operation is improper, reducing the practicality of the device.

[0025] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0026] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0027] Example

[0028] like Figures 1 to 5 As shown, this embodiment includes a fixed plate 1 for connection and a movable plate 23 for unloading the polyimide film during production. A slide rail 2 for easy connection is provided in the center of the top of the fixed plate 1. The inner wall of the slide rail 2 is rotatably connected to a reverse double-threaded rod 3, and a driving motor 11 for providing power is screwed to the end side of the fixed plate 1. The output shaft of the driving motor 11 passes through the side wall of the slide rail 2 and is connected to one end of the reverse double-threaded rod 3. The reverse double-threaded rod 3 is threadedly connected to two threaded blocks 10 for easy movement, and the tops of the two threaded blocks 10 are screwed to two hydraulic rods 12 for easy lifting and adjustment.

[0029] A clamping block 13 is welded to the moving part of one hydraulic rod 12, and a circular arc-shaped moving strip for opening and closing is movably connected to the top of the clamping block 13, and the moving strip is slidably connected to the fixed part of the clamping block 13. A clamping groove 19 for limiting the position is provided at the fixed part of the clamping block 13, and a clamping ring 17 is slidably connected to the inner side wall of the clamping groove 19, and the clamping ring 17 is sleeved on the outer peripheral side of the rotating shaft 15. A support block 14 is welded to the moving part of the other hydraulic rod 12, and a U-shaped ... A stop block is provided on the outer peripheral side of the rotating shaft 15 between the support block 14 and the vertical plate 9 for easy fixation. The limit strip 18 fits with the groove arranged inside the paper tube to complete the fixation of the paper tube and the rotating shaft 15. A rotating motor 16 is screwed to one end of the vertical plate 9. The output shaft of the rotating motor 16 passes through the side wall of the vertical plate 9 and is connected to one end of the rotating shaft 15. The output shaft of the rotating motor 16 rotates through the air, driving the rotating shaft 15 to rotate the paper tube fixed by the limit strip 18, thereby completing the winding of the produced polyimide film, which is easy to use.

[0030] A fixing frame 5 is welded to the top of the fixing plate 1, and a slide groove 8 is provided on the top of the fixing frame 5 for easy movement. A slider 7 for easy movement and limiting is slidably connected to the inner side wall of the slide groove 8. An adjustable electric push rod 6 is screwed to the top of the slider 7. A part of the fixed part of the electric push rod 6 is arranged inside the slider 7, and the bottom two sides of the slider 7 are connected to the moving parts of the two linear motors 4. The fixed parts of the two linear motors 4 are connected to the side walls of the fixing frame 5. The moving part of the electric push rod 6 passes through the slider 7 and is connected to the connecting plate 21. The top of the connecting plate 21 is movably connected to the slider 7. Four symmetrically arranged fixed blocks 20 for connection are arranged on both sides of the connecting plate 21. Both sides of the fixed block 20 are connected to the connecting plate 21 through a straight plate to assist in fixing, thereby improving the structural stability of the device.

[0031] The top screw of the connecting plate is connected with two automatic telescopic columns 26 which are easy to adjust. The moving part of the automatic telescopic column 26 passes through the end face of the connecting plate 21 and is welded to the arc plate 25 which is arranged in an arc shape. The arc plate 25 abuts against the polyimide film wound on the outer peripheral side of the paper tube, which is convenient for auxiliary fixation. A fixed column 24 which is easy to connect is welded at the bottom of the fixed block 20. The bottom of the fixed column 24 is rotatably connected with a movable plate 23 through a set pin shaft. The movable plates 23 are slidably connected with each other, and a limiting plate 22 for limiting is screwed to the bottom of the fixed column 24 and the movable plate 23. The limiting plate 22 can effectively solve the problem of the film fixed inside the fixed column 24 being detached, and is convenient to cooperate with the arc plate 25 to complete the fixation.

[0032] The connecting plate 21 is driven to move by the moving part of the linear motor 4, and the moving part of the electric push rod 6 is coordinated to control the lifting of the connecting plate 21 until the rolled polyimide film passes through the movable plate 23 and enters between the fixed columns 24, and the automatic telescopic column 26 is started to drive the arc plate 25 to move, and the limit plate 22 and the arc plate 25 are fixed. At this time, the moving part of the hydraulic rod 12 welded with the support block 14 is controlled to shrink, and the linear motor 4 is driven to drive the paper tube to move on the surface of the rotating shaft 15 until it abuts against the electric push rod 2 welded with the clamping block 13, and the other electric push rod 12 is controlled to drive the support block 14 to connect with the rotating shaft, open the clamping block 13, and separate the clamping ring 17 and the clamping groove 19 on the outer peripheral side of the rotating shaft 15, so as to facilitate the unwinding of the wound film under the device arranged at the bottom of the connecting plate 21, which is convenient for operation.

[0033] The setting of the limit plate 22 makes it difficult to unroll the polyimide film fixed by the arc plate 25 and the fixed column 24. Therefore, a sliding bar can be set at the bottom of the limit plate 22, and the sliding bar is slidably connected to the T-shaped slideway set at the end of the fixed column 24. A structure similar to an electric push rod is screwed to the side wall of the fixed column 24, and the moving part of the structure is connected to the end side of the limit plate 22 to complete the unloading of the rolled film fixed by the device during the disassembly process. In order to limit and fix the movable plate 23, the slideway set at the end of the fixed column 24 should extend to the bottom of the movable plate 23, and cooperate with the structure similar to the electric push rod set on the side wall of the fixed column 24 to complete the moving part and fixation of the device, which is easy to operate.

[0034] The linear motor 4, the electric push rod 6, the drive motor 11, the hydraulic rod 12, the rotary motor 16 and the automatic telescopic column 26 are all conventional instruments. The working principle, size and model are irrelevant to the function of the present application, so they are not described in detail. The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
