Description

Technical Field

[0001] This invention relates to the field of brightness enhancement film processing technology, specifically to a quantitative cutting device for brightness enhancement film processing. Background Technology

[0002] Brightness enhancement film is an optical film used in the display field to improve the brightness of backlight modules. Its core function is to converge divergent light through optical structures, thereby improving the front brightness and visual effect of liquid crystal displays (LCDs). Its substrate is mostly polymethyl methacrylate (PMMA) or polycarbonate (PC), and the surface is processed with microstructures to form prism arrays or columnar lenses. It uses the principles of total internal reflection and refraction to converge the divergent light from side backlights or straight backlights to the vertical viewing angle. It is often used in conjunction with diffusion films and reflective films and is widely used in display devices such as mobile phones, televisions, and laptops.

[0003] Currently, most brightness enhancement films are often laid flat on a workbench for cutting, which is inefficient and affects the cutting accuracy, thus impacting the subsequent use of the brightness enhancement film. To address this, we propose a quantitative cutting device for brightness enhancement film processing. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a quantitative cutting device for processing brightness enhancement films, which solves the problem that most existing brightness enhancement films are usually laid flat on a workbench for cutting operations, resulting in low operating efficiency, affecting cutting accuracy, and impacting the subsequent use of the brightness enhancement film.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a quantitative cutting device for processing a brightness enhancement film, comprising a base plate, a mounting frame fixedly connected to the upper surface of the base plate, a cutting mechanism provided on the upper surface of the base plate, the cutting mechanism comprising a bracket, the bracket being fixedly connected to the upper surface of the base plate, a first support plate fixedly connected to the upper end of the bracket, a first telescopic rod fixedly connected to the inner wall of the first support plate, a cutter fixedly connected to the driving end of the first telescopic rod, the cutter sliding against the inner wall of the first support plate, and a mounting sleeve fixedly connected to one side of the mounting frame, the inner wall of the mounting sleeve... A second telescopic rod is fixedly connected, and a first pressure plate is fixedly connected to the driving end of the second telescopic rod. A slide rail is fixedly connected to the upper surface of the base plate, and a slider is slidably connected to the inner wall of the slide rail. A carrier rod is fixedly connected to the upper end of the slider, and a stabilizing frame is fixedly connected to one end of the carrier rod. A second support plate is fixedly connected to one side of the stabilizing frame, and a third telescopic rod is fixedly connected to one side of the stabilizing frame. The driving end of the third telescopic rod is fixedly connected to the second pressure plate. Relying on the mechanical structure, the conveying length of the brightness enhancement film is precisely controlled, avoiding errors from manual operation, ensuring consistent cutting length, and improving product quality stability.

[0006] Preferably, the inner wall of the mounting frame is rotatably connected to two guide rollers, and a drive motor is fixedly connected to one side of the mounting frame. The drive end of the drive motor passes through the mounting frame and is fixedly connected to the shaft of one of the guide rollers. During operation, the motor, in conjunction with the screw, drives the slider, the carrier rod, the stabilizer, the second support plate, and the second pressure plate to move. When the chamfer on the second support plate matches the chamfer on the first support plate, the drive motor is controlled to work with the guide rollers to convey the brightness enhancement film forward. When the brightness enhancement film is above the second support plate, the drive motor is turned off.

[0007] Preferably, an adjusting motor is fixedly connected to one side of the slide rail, the drive end of the adjusting motor passes through the slide rail, and a screw is fixedly connected to the drive end of the adjusting motor. One end of the screw is rotatably connected to the inner wall of the slide rail, and the screw is threadedly connected to the inner wall of the slider. This allows for the rapid completion of the cutting operation of the brightness enhancement film, replacing manual laying operation. It eliminates the need for repeated manual adjustments, enables continuous and automated quantitative cutting, significantly reduces the time required for a single operation, and is suitable for mass production.

[0008] Preferably, the first support plate and the first pressure plate are both provided with concave chamfers on the side close to each other, and the second support plate and the second pressure plate are both provided with protruding chamfers on the side close to the first support plate. The protruding chamfers are adapted to the concave chamfers. The third telescopic rod is controlled to drive the second pressure plate to move downward, and the second support plate clamps the brightness enhancement film. Then, the adjustment motor is operated to drive the slider, the carrier rod, the stabilizer, the second support plate and the second pressure plate to move away from the mounting frame, so that the brightness enhancement film can be pulled out to a certain length.

[0009] Preferably, the longitudinal section of the stabilizer is C-shaped and the edges of the stabilizer are rounded. After the brightness enhancement film is pulled to a suitable length, the second telescopic rod is controlled to push the first pressure plate downward, which, together with the first support plate, clamps the other end of the brightness enhancement film. Then, the first telescopic rod is controlled to push the cutter upward to cut the brightness enhancement film. Subsequently, the second telescopic rod drives the first pressure plate to reset, and the third telescopic rod drives the second pressure plate to reset, so that the cut brightness enhancement film can be removed.

[0010] Preferably, the longitudinal section of the support rod is L-shaped, and the corners of the support rod are rounded.

[0011] Preferably, an incremental mechanism is provided on one side of the base plate. The incremental mechanism includes a support rod, which is fixedly connected to one side of the base plate. A card seat is fixedly connected to one end of the support rod. A fourth telescopic rod is fixedly connected to the inner wall of the card seat. A positioning frame is fixedly connected to the driving end of the fourth telescopic rod. A fifth telescopic rod is fixedly connected to the upper end of the positioning frame. An assembly frame is fixedly connected to the driving end of the fifth telescopic rod. Two symmetrically arranged lifting guide rollers are rotatably connected to both sides of the assembly frame. By adding structures such as the positioning frame and lifting guide rollers, when the demand exceeds the conventional range, the limitation of the length of a single slide rail can be broken, and more diversified cutting needs can be adapted.

[0012] Preferably, one side of the assembly frame is rotatably connected to two symmetrically arranged positioning guide rollers.

[0013] Preferably, the height of the fourth telescopic rod is higher than the height of the slide rail, to ensure that the fourth telescopic rod will not interfere with the slide rail during operation.

[0014] Preferably, the distance between the two positioning guide rollers is greater than the distance between the two lifting guide rollers. When the lifting guide rollers move upward, they can work with the positioning guide rollers to lift the brightness enhancement film.

[0015] In summary, the technical effects and advantages of this invention are as follows: 1. In this invention, the conveying length of the brightness enhancement film is precisely controlled by relying on the mechanical structure, avoiding errors caused by manual operation, ensuring consistent cutting length, and improving product quality stability.

[0016] 2. In this invention, the cutting operation of the brightness enhancement film can be completed quickly, replacing the manual spreading operation. There is no need for repeated manual adjustment. It can continuously and automatically cut the film quantitatively, greatly shortening the time of a single operation and making it suitable for mass production.

[0017] 3. In this invention, a positioning frame and lifting guide roller are added. When the demand exceeds the conventional range, the limitation of the length of a single slide rail can be broken, and more diversified cutting needs can be adapted. Attached Figure Description

A slide rail 58 is fixedly connected to the upper surface of the base plate 1. A slider 511 is slidably connected to the inner wall of the slide rail 58. A carrier rod 512 is fixedly connected to the upper end of the slider 511. A stabilizing frame 513 is fixedly connected to one end of the carrier rod 512. A second support plate 514 is fixedly connected to one side of the stabilizing frame 513. A third telescopic rod 515 is fixedly connected to one side of the stabilizing frame 513. A second pressure plate 516 is fixedly connected to the drive end of the third telescopic rod 515. Relying on the mechanical structure, the conveying length of the brightness enhancement film is precisely controlled, avoiding errors from manual operation, ensuring consistent cutting length, and improving product quality stability.

[0022] The inner wall of the mounting frame 2 is rotatably connected to two guide rollers 3. A drive motor 4 is fixedly connected to one side of the mounting frame 2. The drive end of the drive motor 4 passes through the mounting frame 2 and is fixedly connected to the shaft of one of the guide rollers 3. During operation, the adjusting motor 59, in conjunction with the screw 510, drives the slider 511, the carrier rod 512, the stabilizer 513, the second support plate 514, and the second pressure plate 516 to move. When the chamfer on the second support plate 514 matches the chamfer on the first support plate 52, the drive motor 4 is controlled to cooperate with the guide rollers 3 to convey the brightness enhancement film forward. When the brightness enhancement film is above the second support plate 514, the drive motor 4 is turned off.

[0023] The slide rail 58 is fixedly connected to one side of an adjusting motor 59. The driving end of the adjusting motor 59 passes through the slide rail 58. The driving end of the adjusting motor 59 is fixedly connected to a screw 510. One end of the screw 510 is rotatably connected to the inner wall of the slide rail 58. The screw 510 is threadedly connected to the inner wall of the slider 511. This allows for the rapid completion of the cutting operation of the brightness enhancement film, replacing manual laying operation. It eliminates the need for repeated manual adjustments, enabling continuous and automated quantitative cutting, significantly reducing the time required for a single operation, and making it suitable for mass production.

[0024] The first support plate 52 and the first pressure plate 57 are both provided with concave chamfers on the side close to each other. The second support plate 514 and the second pressure plate 516 are both provided with protruding chamfers on the side close to the first support plate 52. The protruding chamfers are adapted to the concave chamfers. The third telescopic rod 515 is controlled to drive the second pressure plate 516 to move downward, and the second support plate 514 clamps the brightness enhancement film. Then, the adjusting motor 59 is operated to drive the slider 511, the carrier rod 512, the stabilizer 513, the second support plate 514 and the second pressure plate 516 to move away from the mounting frame 2, so that the brightness enhancement film can be pulled out to a certain length.

[0025] The stabilizer 513 has a C-shaped longitudinal section and rounded edges. After pulling the brightness enhancement film to a suitable length, the second telescopic rod 55 is controlled to push the first pressure plate 57 downward, which, together with the first support plate 52, clamps the other end of the brightness enhancement film. Then, the first telescopic rod 53 is controlled to push the cutter 54 upward to cut the brightness enhancement film. Subsequently, the second telescopic rod 55 drives the first pressure plate 57 to reset, and the third telescopic rod 515 drives the second pressure plate 516 to reset, so that the cut brightness enhancement film can be removed.

[0026] The longitudinal section of the support rod 512 is L-shaped, and the corners of the support rod 512 are rounded.

[0027] An incremental mechanism 6 is provided on one side of the base plate 1. The incremental mechanism 6 includes a support rod 61, which is fixedly connected to one side of the base plate 1. One end of the support rod 61 is fixedly connected to a card seat 62. The inner wall of the card seat 62 is fixedly connected to a fourth telescopic rod 63. The driving end of the fourth telescopic rod 63 is fixedly connected to a positioning frame 64. The upper end of the positioning frame 64 is fixedly connected to a fifth telescopic rod 66. The driving end of the fifth telescopic rod 66 is fixedly connected to an assembly frame 67. Two symmetrically arranged lifting guide rollers 68 are rotatably connected to both sides of the assembly frame 67. By adding structures such as the positioning frame 64 and the lifting guide rollers 68, when the demand exceeds the conventional range, the length limitation of a single slide rail 58 can be broken, and more diversified cutting needs can be adapted.

[0028] Among them, two symmetrically arranged positioning guide rollers 65 are rotatably connected to one side of the assembly frame 67.

[0029] The height of the fourth telescopic rod 63 is higher than that of the slide rail 58, ensuring that the fourth telescopic rod 63 will not interfere with the slide rail 58 during operation.

[0030] The distance between the two positioning guide rollers 65 is greater than the distance between the two lifting guide rollers 68. When the lifting guide rollers 68 move upward, they can work with the positioning guide rollers 65 to lift the brightness enhancement film.

[0031] Working principle of this invention: During operation, the adjusting motor 59, in conjunction with the screw 510, drives the slider 511, the carrier rod 512, the stabilizer 513, the second support plate 514, and the second pressure plate 516 to move. When the chamfer on the second support plate 514 matches the chamfer on the first support plate 52, the drive motor 4, in conjunction with the guide roller 3, is controlled to convey the brightness enhancement film forward. When the brightness enhancement film is above the second support plate 514, the drive motor 4 is turned off. Then, the third telescopic rod 515 is controlled to drive the second pressure plate 516 to move downward, cooperating with the second support plate 514 to clamp the brightness enhancement film. Then, the operation... The adjusting motor 59 drives the slider 511, carrier rod 512, stabilizer 513, second support plate 514, and second pressure plate 516 to move away from the mounting frame 2. After pulling out a suitable length, the second telescopic rod 55 is controlled to push the first pressure plate 57 downward, which, together with the first support plate 52, clamps the other end of the brightness enhancement film. Then, the first telescopic rod 53 is controlled to push the cutter 54 upward to cut the brightness enhancement film. Subsequently, the second telescopic rod 55 drives the first pressure plate 57 to reset, and the third telescopic rod 515 drives the second pressure plate 516 to reset, allowing the cut brightness enhancement film to be removed. Repeat the above operation to continuously perform quantitative cutting of the brightness enhancement film. When the brightness enhancement film to be cut is greater than the length of the slide rail 58, the second pressure plate 516, in conjunction with the second support plate 514, clamps and pulls the brightness enhancement film to extend. When the slider 511 moves to the other end of the slide rail 58, the adjusting motor 59 is turned off, and the positioning frame 64 is moved closer to the slide rail 58 by the fourth telescopic rod 63. When the positioning frame 64 moves above the slide rail 58, the positioning guide roller 65 and the lifting guide roller 68 are located above and below the brightness enhancement film, respectively. Then, the assembly frame 67 and the lifting guide roller 68 are pushed upward by the fifth telescopic rod 66 to push the brightness enhancement film upward, thereby increasing the cutting range of the equipment. After the brightness enhancement film is pulled to the required length, the above operation is repeated to cut the brightness enhancement film. Then, the brightness enhancement film is removed, and the components are reset to prepare for the next operation.
