Description

Technical Field

[0001] This utility model relates to the field of polyimide film production technology, specifically to a polyimide film positioning and cutting structure. Background Technology

[0002] Polyimide film is a high-performance polymer material widely used in various fields. It is mainly made from polyimide resin through a specific process. After the polyimide film is produced, it needs to be cut to facilitate its installation on other equipment.

[0003] According to CN213439840U, a cutting device for polyimide film with positioning function is described. During operation, a discharge conveyor belt places the polyimide film to be cut onto a feeding conveyor belt. A rolling roller above the feeding conveyor belt rolls the surface of the polyimide film. The feeding conveyor belt drives the polyimide film forward under the action of surface friction. By controlling the drive motor to drive the crankshaft to rotate, the crankshaft can synchronously drive the cutter to perform a reciprocating up-and-down telescopic motion through the connecting rod. Through the cooperation of the cutter and the feeding conveyor belt, the polyimide film can be cut quickly. The structure is simple, the operation is convenient, and the use is more convenient. At the same time, the rolling roller rolls the polyimide film to achieve a smoothing effect on the surface of the polyimide film, avoiding wrinkles on the surface of the polyimide film during cutting.

[0004] The above-mentioned feeding conveyor belt and discharging conveyor belt can be used to transport polyimide film. However, when using a conveyor belt to transport it, the film is prone to movement during transportation due to the small friction between the film and the conveyor belt and the lack of limiting structure, which affects the accuracy of cutting.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 and Figure 5As shown, in this embodiment, the polyimide film positioning and cutting structure includes a support base 1, a side plate 2 fixedly connected to the top of the support base 1, a threaded rod 3 rotatably connected inside the side plate 2, a threaded sleeve 5 threadedly connected to the surface of the threaded rod 3, a turntable 4 fixedly connected to the end of the threaded rod 3 away from the threaded sleeve 5, a limiting plate 6 fixedly connected to the end of the threaded sleeve 5 away from the threaded rod 3, a sliding sleeve 7 fixedly connected to the side of the limiting plate 6 near the threaded sleeve 5, a limiting groove 8 formed in the inner wall of the sliding sleeve 7, a first sliding rod 9 slidably connected inside the sliding sleeve 7, and a limiting block 10 fixedly connected to the surface of the first sliding rod 9.

[0024] By rotating the turntable 4, the threaded rod 3 is driven to rotate inside the side plate 2. Since the bottom of the limiting plate 6 is in contact with the conveyor belt 11, the limiting block 10 and the limiting groove 8 are matched, causing the threaded sleeve 5 to drive the limiting plate 6 to move back and forth, thereby adjusting the distance between the two limiting plates 6 and making them contact the two sides of the polyimide film, realizing guidance and limiting during the movement, avoiding deviation during conveying, and ensuring stability during the movement through the relative sliding of the sliding sleeve 7 and the first sliding rod 9.

[0025] There are two side plates 2. The surface of the threaded rod 3 is provided with a stop block. The stop block is in contact with the side plate 2. The limiting groove 8 and the limiting block 10 are adapted to each other. The first sliding rod 9 is fixedly connected to the side plate 2.

[0026] The support base 1 is equipped with a conveyor belt 11. A connecting frame 12 is fixedly connected to the top of the support base 1. A cylinder 13 is fixedly connected to the top of the connecting frame 12. A lifting frame 14 is fixedly connected to the bottom of the cylinder 13. A spring rod 15 is fixedly connected to the top of the lifting frame 14. A mounting base 16 is fixedly connected to the bottom of the lifting frame 14. A cutting tool 17 is installed inside the mounting base 16.

[0027] By setting conveyor belts 11 on both sides of the support base 1, the transportation of polyimide film is facilitated. The cylinder 13 is activated, and its output rod drives the lifting frame 14 to move, thereby adjusting the height of the cutting blade 17. The cutting blade 17 and the mounting base 16 are connected by bolts, which facilitates the installation and removal of the cutting blade 17.

[0028] There are two conveyor belts 11. The connecting frame 12 adopts a U-shaped structure. The lifting frame 14 is located inside the connecting frame 12. There are two spring rods 15. The two spring rods 15 are fixedly connected to the connecting frame 12. The cutting blade 17 and the mounting base 16 are connected by bolts.

[0029] A drive motor 18 is fixedly connected to the side of the lifting frame 14 away from the side plate 2. A two-way lead screw 19 is fixedly connected to the output shaft of the drive motor 18. An adjusting plate 20 is threadedly connected to the surface of the two-way lead screw 19. A guide rod 21 is slidably connected inside the adjusting plate 20. A calibration block 22 is fixedly connected to the top of the adjusting plate 20. A scale 23 is fixedly connected to the front of the lifting frame 14.

[0030] By starting the drive motor 18, its output shaft drives the bidirectional lead screw 19 to rotate, and the two adjusting plates 20 move on the surface of the guide rod 21, moving closer or further away from each other, thereby adjusting the distance between the two adjusting plates 20. A scale 23 is provided on one side of the lifting frame 14, and the adjusting plates 20 can be precisely controlled by observing the distance between the two pairs of scale blocks 22 to adapt to the size of the polyimide film cutting.

[0031] The bidirectional lead screw 19 is rotatably connected to the lifting frame 14, and there are two adjusting plates 20. The guide rod 21 is fixedly connected to the lifting frame 14.

[0032] The adjusting plate 20 has a second slide rod 24 slidably connected inside. A return spring 25 is movably sleeved on the surface of the second slide rod 24. A pressure plate 26 is fixedly connected to the bottom end of the second slide rod 24, and a baffle 27 is fixedly connected to the top end of the second slide rod 24.

[0033] By having the pressure plate 26 come into contact with the polyimide film in advance during the downward movement of the lifting frame 14, the two ends of the film are positioned to facilitate cutting. An infrared sensor is provided on the pressure plate 26 near the drive motor 18 to detect the position of the polyimide film and control the operation of the cylinder 13.

[0034] This utility model provides a positioning and cutting structure for polyimide films, and its specific working principle is as follows:

[0035] In use, the polyimide film is placed on the conveyor belt 11 on the side of the support base 1 near the side plate 2. The conveyor belt 11 moves the polyimide film. The rotating turntable 4 causes the threaded rod 3 to rotate inside the side plate 2. Since the bottom of the limiting plate 6 is in contact with the conveyor belt 11, the threaded sleeve 5 moves the limiting plate 6 back and forth and contacts both sides of the polyimide film, thus guiding and limiting the movement. After the polyimide film moves to the pressure plate 26 near the drive motor 18, the cylinder 13 is activated. Its output rod drives the lifting frame 14 to move down. The pressure plate 26 contacts the polyimide film, and the second slide rod 24 slides on the adjusting plate 20. The return spring 25 is squeezed and contracted. The lifting frame 14 continues to move down and drives the cutting blade 17 to cut the polyimide film. After cutting, the conveyor belt 11 on the other side of the support base 1 works and moves the polyimide film out for easy collection.

[0036] 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.
