Description

Technical Field

[0001] This utility model relates to the field of optical thin film processing equipment technology, specifically to an optical thin film processing correction device. Background Technology

[0002] Optical thin films are a type of optical medium material composed of thin, layered media that transmits light beams through interfaces.

[0003] As a high-precision material, the surface flatness and the tightness of the rolled-up optical film directly affect the quality and performance of the final product. During the winding process of coated optical films, the optical films are prone to positional deviation due to various factors such as external forces and vibrations during transportation. While adding limiting plates on both sides of the conveying equipment to restrict the optical film deviation, it is impossible to effectively adjust the position of the limiting plates according to the width of the optical film. Furthermore, the sides of the optical film are prone to contacting and pressing against the limiting plates, causing them to bulge and resulting in unevenness and poor correction effect. Therefore, it is necessary to provide an optical film processing correction device to solve the above problems. Utility Model Content

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.

[0027] Please see Figure 1-5 An optical thin film processing correction device, comprising:

[0028] Mounting frame 1, with a through hole in the center of one side wall of mounting frame 1;

[0029] Conveying roller 3, several conveying rollers 3 are provided, and several conveying rollers 3 are rotatably arranged at equal distances inside the upper end of the mounting frame 1;

[0030] A correction component 5 is provided in the middle of the interior of the mounting frame 1, and a U-shaped frame 4 is provided in the middle of the upper surface of the mounting frame 1. A limit component 6 is provided on the U-shaped frame 4.

[0031] The correction assembly 5 includes a correction plate 505. There are two correction plates 505, which are respectively located on both sides of the upper end of the conveyor roller 3 inside the mounting frame 1.

[0032] The correction assembly 5 also includes a slide rail 501, a slider 502, a vertical rod 503, a connecting plate 504, and a bidirectional screw 507. There are two slide rails 501, which are arranged parallel to each other on the bottom surface inside the mounting frame 1. The slider 502 is slidably disposed inside the slide rail 501. The vertical rod 503 is disposed at both ends of the lower surface of the correction plate 505. The lower end of the vertical rod 503 passes through the gap between the conveying rollers 3 and is connected to the slider 502. The connecting plate 504 is disposed below the correction plate 505. Both ends of the connecting plate 504 are respectively connected to the vertical rods 503 at both ends of the correction plate 505. By providing the slide rail 501, it is convenient to install the slider 502 and the vertical rod 503. The correction plate 505 is installed on the upper end of the vertical rod 503, thereby realizing that the correction plate 505 can slide back and forth.

[0033] The connecting plate 504 is threaded with a bidirectional screw 507. The threads at both ends of the bidirectional screw 507 are in opposite directions. One end of the bidirectional screw 507 passes through a through hole in the center of the side wall of the mounting frame 1 and is equipped with a knob. By rotating the knob, the bidirectional screw 507 can be rotated synchronously. Under the limiting action of the slide rail 501, the connecting plate 504 moves along the bidirectional screw 507. During the movement of the two connecting plates 504, the upright rod 503 can drive the two correction plates 505 to move synchronously, moving closer or further apart from each other. This allows for effective adjustment of the distance between the two correction plates 505, adapting to optical films of different widths, ensuring that the optical film is in the center position, and preventing its left and right positions from shifting.

[0034] The limiting component 6 includes a base plate 601, a threaded rod 602, and a handle 603. The base plate 601 is located inside the U-shaped frame 4. The threaded rod 602 is rotatably located at the center of the upper surface of the base plate 601. A threaded hole 401 is provided at the center of the upper wall of the U-shaped frame 4. The upper end of the threaded rod 602 passes through the threaded hole 401 and is connected to the handle 603. The threaded rod 602 is threadedly connected to the U-shaped frame 4. By rotating the handle 603, the threaded rod 602 can be driven to rotate synchronously and move up and down. During the up and down movement of the threaded rod 602, the base plate 601 can be driven to move up and down synchronously.

[0035] The base plate 601 has limit shafts 605 at both ends, and limit rollers 606 are rotatably fitted on the outer surface of the limit shafts 605. The correction plate 505 has clearance slots 506 for the limit rollers 606 to pass through. Limit rings 402 are provided at the middle of both sides of the upper wall of the U-shaped frame 4. Limit slide rods 604 are provided on both sides of the upper surface of the base plate 601. The upper end of the limit slide rod 604 passes through the limit ring 402 and is slidably connected to the limit ring 402. By setting the limit slide rods 604, the base plate 601 can be effectively limited, ensuring that the base plate 601 can move up and down in the vertical direction. The limit rollers 606 at both ends of the base plate 601 can effectively limit the optical film, prevent the optical film from bulging, and ensure the flatness of the optical film.

[0036] Among them, the four corners of the lower surface of the mounting frame 1 are provided with support feet 2. By providing support feet 2, the mounting frame 1 can be effectively supported to ensure the overall stability.

[0037] Working principle: By rotating the knob, the bidirectional screw 507 can be rotated synchronously. Under the limiting action of the slide rail 501, the connecting plate 504 moves along the bidirectional screw 507. During the movement of the two connecting plates 504, the upright rod 503 can drive the two correction plates 505 to move synchronously, moving closer or further apart from each other, thereby effectively adjusting the distance between the two correction plates 505 to adapt to optical films of different widths, ensuring that the optical film is in the center position and avoiding its left and right position deviation.

[0038] Furthermore, rotating the handle 603 can drive the threaded rod 602 to rotate synchronously and move up and down. During the up and down movement of the threaded rod 602, it can drive the base plate 601 to move up and down synchronously. As a result, the limiting rollers 606 at both ends of the base plate 601 can effectively limit the optical film, prevent the optical film from bulging, and ensure the flatness of the optical film.
