Description

Technical Field

[0001] The utility model relates to the technical field of optical film production, in particular to a flattening device for optical film production. Background Art

[0002] An optical film is a high-precision thin film material, which is widely used in multiple fields. During the production process of the optical film, it is necessary to flatten it to avoid wrinkles during subsequent processing. Currently, when flattening the optical film, the flattening effect is low, which affects the quality of the optical film.

[0003] In the patent application with the publication number of CN219971369U in the prior art, a flattening device for optical film production is disclosed, including a workbench. This device enables the flattening roller to rotate on the optical film, thereby being able to flatten the optical film and improving the quality of the optical film.

[0004] The length of the optical film in a wrinkled state is smaller than that in a flattened state. When the optical film is flattened from the wrinkled state, the length of the optical film will elongate. And this device clamps both ends of the optical film. To enable the optical film to be normally unfolded, it is necessary to continuously loosen and clamp both ends of the optical film to provide space for the optical film to unfold. The process of flattening the optical film is complex, thereby reducing the practicability of this device. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a flattening device for optical film production, aiming to solve the problem that the length of the optical film in a wrinkled state is smaller than that in a flattened state. When the optical film is flattened from the wrinkled state, the length of the optical film will elongate. And this device clamps both ends of the optical film. To enable the optical film to be normally unfolded, it is necessary to continuously loosen and clamp both ends of the optical film to provide space for the optical film to unfold. The process of flattening the optical film is complex, thereby reducing the practicability of this device.

[0006] To achieve the above purpose, the utility model provides a flattening device for optical film production, including a workbench and a flattening mechanism. The flattening mechanism includes a fixing component, two cylinders, a mounting plate, a mounting frame, a driving component, a moving block, two telescopic components, a mounting frame, a rotating roller, and a pressing roller. The fixing component is arranged at one end of the workbench. The two cylinders are respectively fixedly connected to both ends of the workbench. The mounting plate is fixedly connected to the output ends of the two cylinders. The mounting frame is fixedly connected to the mounting plate and is located below the mounting plate. The driving component is arranged on the mounting frame. The moving block is arranged on the driving component. The two telescopic components are arranged between the moving block and the mounting frame. Both ends of the rotating roller are fixedly connected to the mounting frame. The pressing roller is rotatably connected to the rotating roller.

[0007] Among them, the fixing component includes a fixing frame, an electric telescopic rod, and a pressing plate. The fixing frame is slidably connected to the workbench and penetrates through the workbench. The electric telescopic rod is fixedly connected to the lower end of the workbench. The output end of the electric telescopic rod is fixedly connected to the fixing frame. The pressing plate is fixedly connected to the fixing frame and is located above the workbench.

[0011] For a flattening device for optical film production according to the present utility model, when flattening an optical film, the optical film is placed on the workbench. The fixing component clamps and fixes one end of the optical film on the workbench. Then, control the two cylinders to contract, so that the pressing roller contacts the optical film, and the two telescopic components slightly contract, so that the pressing roller fits tightly with the optical film. Start the driving component. The driving component controls the moving block and the pressing roller to move in a direction away from the fixing component. The pressing roller rolls on the optical film to flatten the optical film. When the driving component controls the pressing roller to move to the farthest position from the fixing component, start the two cylinders simultaneously. The output ends of the two cylinders extend, the mounting plate moves upward, and the pressing roller leaves the workbench. Control the moving block and the pressing roller to move to the position closest to the fixing component through the driving component, and then repeat the above steps to flatten the optical film.

[0019] The present utility model provides a flattening device for optical film production, including a workbench 101 and a flattening mechanism. The flattening mechanism includes a fixing component, two cylinders 105, a mounting plate 106, a mounting bracket 116, a driving component, a moving block 109, two telescopic components, a mounting frame 112, a rotating roller 113 and a pressing roller 114. The fixing component includes a fixed frame 102, an electric telescopic rod 103, an anti-slip pad 115 and a pressing plate 104. The driving component includes a driving motor 107 and a lead screw 108. The telescopic component includes a telescopic spring 111 and a telescopic rod 110. Through the foregoing solution, the problem that the length of the optical film in the wrinkled state is smaller than that of the optical film in the flattened state, and when the optical film is flattened from the wrinkled state, the length of the optical film will elongate, and the device clamps both ends of the optical film. To enable the optical film to be normally unfolded, the two ends of the optical film need to be continuously loosened and clamped to provide space for the optical film to unfold, and the process of flattening the optical film is complex, thereby reducing the practicability of the device is solved.

[0020] In this embodiment, the fixing component is arranged at one end of the workbench 101. Two cylinders 105 are respectively fixedly connected to both ends of the workbench 101. The mounting plate 106 is fixedly connected to the output ends of the two cylinders 105. The mounting frame 116 is fixedly connected to the mounting plate 106 and is located below the mounting plate 106. The driving component is arranged on the mounting frame 116. The moving block 109 is arranged on the driving component. Two telescopic components are arranged between the moving block 109 and the mounting frame 112. Both ends of the rotating roller 113 are fixedly connected to the mounting frame 112. The pressing roller 114 is rotatably connected to the rotating roller 113. When flattening the optical film, place the optical film on the workbench 101. The fixing component clamps and fixes one end of the optical film on the workbench 101. Then control the two cylinders 105 to contract, so that the pressing roller 114 contacts the optical film, and the two telescopic components slightly contract, so that the pressing roller 114 fits tightly with the optical film. Start the driving component. The driving component controls the moving block 109 and the pressing roller 114 to move in a direction away from the fixing component. The pressing roller 114 rolls on the optical film to flatten the optical film. When the driving component controls the pressing roller 114 to move to the farthest end from the fixing component, start the two cylinders 105 at the same time. The output ends of the two cylinders 105 extend, the mounting plate 106 moves upward, and the pressing roller 114 leaves the workbench 101. Control the moving block 109 and the pressing roller 114 to move to the position closest to the fixing component through the driving component, and then repeat the above steps to flatten the optical film. When flattening the optical film, the pressing roller 114 only rolls from the position closest to the fixing component to the position farthest from the fixing component. The process of flattening the optical film will be simple, thereby increasing the practicability of the device.

[0021] Further, the fixed frame 102 is slidably connected to the workbench 101 and penetrates through the workbench 101. The electric telescopic rod 103 is fixedly connected to the lower end of the workbench 101. The output end of the electric telescopic rod 103 is fixedly connected to the fixed frame 102. The pressing plate 104 is fixedly connected to the fixed frame 102 and is located above the workbench 101.

[0022] Further, the anti-slip pad 115 is fixedly connected to the workbench 101 and is located below the pressing plate 104.

[0023] In this embodiment, when fixing the optical film, place the optical film on the workbench 101, and place one end of the optical film under the pressing plate 104. Start the electric telescopic rod 103. The output end of the electric telescopic rod 103 extends, driving the fixing frame 102 and the pressing plate 104 to move downward. The pressing plate 104 clamps one end of the optical film. The anti-slip pad 115 increases the friction between the workbench 101 and the optical film, ensuring that the optical film does not fall off between the pressing plate 104 and the workbench 101 when the optical film is flattened.

[0024] Further, the drive motor 107 is fixedly connected to the mounting frame 116. The lead screw 108 is fixedly connected to the output end of the drive motor 107 and extends into the mounting frame 116. The moving block 109 is threadedly connected to the lead screw 108.

[0025] In this embodiment, when controlling the movement of the pressing roller 114, start the drive motor 107. The drive motor 107 drives the lead screw 108 to rotate. The moving block 109 and the pressing roller 114 move following the rotation of the lead screw 108. By controlling the rotation direction of the lead screw 108 by the drive motor 107, the moving direction of the moving block 109 and the pressing roller 114 is further controlled.

[0026] Further, both ends of the telescopic spring 111 are fixedly connected to the moving block 109 and the mounting frame 112 respectively. Both ends of the telescopic rod 110 are fixedly connected to the moving block 109 and the mounting frame 112 respectively and are located inside the telescopic spring 111.

[0027] In this embodiment, when the pressing roller 114 rolls on the optical film, the two telescopic springs 111 are in a contracted state. The two springs provide a downward pressure for the pressing roller 114, ensuring that the pressing roller 114 can roll better on the optical film.

[0028] When using the present utility model to flatten an optical film, place the optical film on the workbench 101, and place one end of the optical film under the pressing plate 104. Start the electric telescopic rod 103. The output end of the electric telescopic rod 103 extends, driving the fixed frame 102 and the pressing plate 104 to move downward. The pressing plate 104 clamps one end of the optical film. The anti-slip pad 115 increases the friction between the workbench 101 and the optical film, ensuring that the optical film will not fall off between the pressing plate 104 and the workbench 101 when the optical film is flattened. Then control the two cylinders 105 to contract, so that the pressing roller 114 contacts the optical film, and the two telescopic springs 111 and the two telescopic rods 110 slightly contract, so that the pressing roller 114 fits closely with the optical film. Start the drive motor 107. The drive motor 107 controls the moving block 109 and the pressing roller 114 to move away from the fixed frame 102. The pressing roller 114 rolls on the optical film to flatten the optical film. When the drive motor 107 controls the pressing roller 114 to move to the farthest end from the fixed frame 102, start the two cylinders 105 at the same time. The output ends of the two cylinders 105 extend, the mounting plate 106 moves upward, and the pressing roller 114 leaves the workbench 101. Control the moving block 109 and the pressing roller 114 to move to the position closest to the fixed component through the drive motor 107, and then repeat the foregoing steps to flatten the optical film. When flattening the optical film, the pressing roller 114 only rolls from the position closest to the fixed frame 102 to the position farthest from the fixed frame 102. The process of flattening the optical film is simple, thereby increasing the practicability of the device.

[0029] The above-disclosed is only a preferred embodiment of the present application, and it cannot be used to limit the scope of rights of the present application. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
