Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of optical film processing equipment, specifically to an optical film cutting device. Background Technology
[0002] Optical films are a type of optical medium material composed of thin, layered media that propagate light beams through interfaces. They are created by depositing or coating one or more dielectric or metal films onto optical elements, utilizing the principle of light interference to alter the optical properties of the carrier. Optical films possess various properties, such as brightening, diffusion, and reflection, and can be designed and manufactured according to specific application requirements. During the processing of optical films, cutting is necessary to produce them to the appropriate dimensions.
[0003] Most existing optical film cutting devices use clamping devices to cut optical films. However, simply using clamping devices to fix the optical film can easily lead to misalignment during the cutting process, resulting in poor cutting quality. Furthermore, the cutting process requires manual placement of the optical film, leading to low cutting efficiency. Utility Model Content

[0017] The embodiments of the technical scheme of the optical film cutting device will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the optical film cutting device, and therefore only serve as examples, and cannot limit the protection scope of the optical film cutting device.
[0018] Please refer to Figures 1-2 , an optical film cutting device, comprising a frame 1, a conveying belt 2 is drivenly arranged on the frame 1, a bottom plate 3 is arranged on the bottom of the frame 1, a mounting frame 4 is installed on the bottom plate 3, a cutting mechanism is slidably arranged in the mounting frame 4, an auxiliary positioning mechanism is installed on the cutting mechanism, and a positioning mechanism is installed on the two inner sides of the mounting frame 4, and the positioning mechanism and the conveying belt 2 are slidably arranged.
[0019] In actual use, the optical film is transmitted by the conveying belt 2, the optical film is cut by the cutting mechanism, the optical film is positioned by the positioning mechanism and the auxiliary positioning mechanism, and the optical film is cut better, and the utility model has high practicability.
[0020] In the embodiment, the cutting mechanism comprises a lifting frame 6 and a cutting knife 12. The cutting knife 12 is fixed to the bottom of the lifting frame 6. The two inner sides of the mounting frame 4 are provided with sliding grooves 5. The two ends of the lifting frame 6 are slidingly arranged in the sliding grooves 5. The inner top of the mounting frame 4 is provided with a hydraulic cylinder 7. The extension end of the hydraulic cylinder 7 is connected with the lifting frame 6. Specifically, the lifting frame 6, the cutting knife 12 and the auxiliary positioning mechanism can be lifted by starting the hydraulic cylinder 7, so that the optical film can be cut.
[0021] The length of the cutting knife 12 is smaller than the width of the conveying belt 2. In this way, the cutting knife 12 can cut the optical film on the conveying belt 2 without cutting the frame 1. The conveying belt 2 can be driven by an output motor to drive the conveying belt 2. The design of the conveying belt 2 belongs to the prior art, and thus will not be described in detail.
[0022] In the embodiment, the auxiliary positioning mechanism is provided with two groups, which are arranged on the two sides of the cutting knife 12. The auxiliary positioning mechanism comprises a telescopic connecting rod 13 and an auxiliary pressing block 14. The telescopic connecting rod 13 is fixed to the lifting frame 6. The auxiliary pressing block 14 is installed at the extension end of the telescopic connecting rod 13. Specifically, the telescopic connecting rod 13 and the auxiliary pressing block 14 can be lifted by lifting the lifting frame 6. Since the height of the telescopic connecting rod 13 and the auxiliary pressing block 14 is higher than that of the cutting knife 12, the auxiliary pressing block 14 can first contact the optical film when the lifting frame 6 is lifted, so that the optical film can be positioned.
[0023] In the embodiment, the positioning mechanism is provided with two groups, which are installed at the two inner sides of the mounting frame 4. The positioning mechanism comprises a first air cylinder 8, a first stop block 9, a second air cylinder 10 and a second stop block 11. The first air cylinder 8 and the second air cylinder 10 are synchronously arranged at the inner side of the mounting frame 4. The first stop block 9 is installed at the extension end of the first air cylinder 8. The second stop block 11 is installed at the extension end of the second air cylinder 10. The first stop block 9 and the second stop block 11 are slidingly arranged on the conveying belt 2. The first stop block 9 is arranged in an L shape. The second stop block 11 is arranged in a cuboid shape. Specifically, the first stop block 9 and the second stop block 11 can be moved by starting the first air cylinder 8 and the second air cylinder 10. The L end of the first stop block 9 can frame the optical film. The end faces of the first stop block 9 and the second stop block 11 can be inwardly pressed into the optical film by continuously controlling the first air cylinder 8 and the second air cylinder 10, so that the positioning of the optical film is completed.
[0024] The first cylinder 8 and the second cylinder 10 can be controlled by a controller to start synchronously. Setting the first cylinder 8 and the second cylinder 10 to start synchronously is prior art, so it will not be described in detail in the specification and the accompanying drawings.
[0025] The width of the mounting bracket 4 is set according to actual needs, and the distance between the first stop block 9 and the second cylinder 10 is set according to the width of the cut optical film.
[0026] Working principle: The optical film is placed on the conveyor belt 2. The optical film is transported by starting the conveyor belt 2, and the first cylinder 8 and the second cylinder 10 are started, so that the L end of the first stop 9 can frame the optical film, and the optical film to be cut is initially limited. The conveyor belt 2 is closed, and the first cylinder 8 and the second cylinder 10 are started again, so that the end faces of the first stop 9 and the second stop 11 can press inward against the optical film, thereby completing the positioning of the optical film. After the positioning is completed, the hydraulic cylinder 7 is started, which drives the lifting frame 6, the cutting shears 12 and the auxiliary positioning mechanism to move. The auxiliary positioning mechanism provides auxiliary positioning for the optical film and reverse movement, and the cutting shears 12 cuts the optical film.
