[0002] Optical films are widely used in electronic displays, lighting, optical instruments and other fields. Their surface quality directly affects the optical performance and use effect of the product. However, during the production and processing of optical films, static electricity is easily generated on the surface of the optical film due to friction and other reasons. This static electricity will absorb dust particles in the air, causing surface contamination of the optical film, which in turn affects the optical transmittance and imaging quality of the product.

[0003] In the existing technology, the static electricity elimination and dust removal methods of traditional optical films are mainly through ion wind static electricity removal, roller wiping cleaning and other methods; however, the existing wiping cleaning method often requires contact with the surface of the optical film, which can easily cause surface scratches and affect the optical quality of the product; in addition, although relying solely on ion wind can reduce static electricity, it cannot effectively remove tiny dust on the surface of the optical film, and the cleaning effect is limited.

Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0029] like Figures 1 to 5 As shown, the embodiment of the utility model provides a surface static removal device for optical film, including a frame 1, a film conveyor belt 2, an ion wind bar 3, an upper roller 41, a lower roller 42, a linkage drive mechanism 5, a dust-sticking roller 6 and a push-pull mechanism 7;

[0030] A support seat 10 is provided on both sides of the middle part of the frame 1, and the upper roller 41 and the lower roller 42 are respectively provided on the support seat 10, and a gap is formed between the upper roller 41 and the lower roller 42 for the optical film to pass through, and the film conveyor belt 2 is provided on both sides of the frame 1, and the film conveyor belt 2 is used to convey the optical film, and the linkage drive mechanism 5 is provided on the side wall of the support seat 10, and is used to drive the lower roller and the film conveyor belt 2 to rotate synchronously; an appropriate gap is formed between the upper roller 41 and the lower roller 42, so that the optical film can pass smoothly under the clamping action of the upper roller 41 and the lower roller 42, and the linkage drive mechanism 5 can drive the lower roller 42 and the film conveyor belt 2 to rotate synchronously. Such an arrangement can avoid the problem of inconsistent speed of the optical film during the conveying process, and enable the optical film to maintain continuous and stable movement during the cleaning and static removal process.

[0031] A fixing plate 11 is provided between the support seats 10 on both sides of the frame 1, and the ion wind rod 3 is provided on the outer wall of the fixing plate 11. A plurality of vertically arranged air outlet nozzles 30 are provided at the bottom of the ion wind rod 3. The ion wind rod 3 is used to blow charged air toward the optical diaphragm; the ion wind rod 3 is located directly above the area where the optical diaphragm passes, so that the ion wind rod 3 can evenly cover the entire surface of the optical diaphragm, ensuring that the static electricity on the surface of the optical diaphragm can be fully neutralized during the transportation process, thereby reducing dust adsorption.

[0032] The sticky roller 6 is disposed above the upper roller 41. The outer surface of the sticky roller 6 is coated with a tape for absorbing dust. The push-pull mechanism 7 is connected to the sticky roller 6 and is used to drive the sticky roller 6 to move along the width direction of the frame 1. The sidewall of the support base 10 is provided with an escape groove 101 for withdrawing the sticky roller 6. The outer surface of the sticky roller 6 is coated with a sticky tape that absorbs dust particles in the surrounding air. When the ion wind bar 3 neutralizes the static electricity on the optical film, the released dust will be suspended around the optical film. The sticky roller 6 can effectively absorb these suspended particles, achieving indirect dust removal and effectively improving the cleanliness of the optical film surface. The tape on the sticky roller 6 will gradually absorb a large amount of dust, resulting in a decrease in its adsorption capacity. The provision of the push-pull mechanism 7 allows the user to easily withdraw the sticky roller 6 from the frame 1 to facilitate tape replacement, ensuring that the sticky roller 6 maintains good dust absorption performance.

[0033] like Figure 1 As shown, further, a dust hood 8 is included, and the dust hood 8 is arranged on the top of the support base 10. The dust hood 8 is connected to the negative pressure generating device to generate a negative pressure airflow that causes the dust to flow upward. With such an arrangement, when the ion wind rod 3 eliminates the static electricity on the optical diaphragm and releases the dust particles on the surface, these particles can be sucked into the dust hood 8 or stick to the dust-sticking roller 6 under the guidance of the negative pressure airflow, effectively preventing the dust from being suspended in the air or re-attaching to the optical diaphragm, thereby improving the dust removal effect.

[0034] like Figure 4 and Figure 5As shown, the push-pull mechanism 7 further includes an outer rail 71, an inner rail 72, a push-pull bracket 73, and a push-pull handle 74. The outer rail 71 is provided on the inner side wall of the fixed plate 11. The inner rail 72 is slidably connected to the outer rail 71 via a ball bearing. The inner rail 72 can move laterally relative to the outer rail 71. The push-pull bracket 73 is connected to the inner rail 72 on both sides. The sticky roller 6 is provided on the push-pull bracket 73. The push-pull handle 74 is provided on the outside of the push-pull bracket 73 and is used to push the sticky roller 6 to move. When the tape on the sticky roller 6 is covered with dust, the operator can pull the push-pull handle 74 to slide the push-pull bracket 73 and the sticky roller 6 laterally out of the avoidance groove 101 and out of the outer rail 71, thereby facilitating the replacement of the tape. After the replacement is completed, the sticky roller 6 can be pushed back to its original position by the push-pull handle 74 for continued use.

[0035] like Figure 4 As shown, the device further includes a lifting assembly 75, which is disposed on the push-pull bracket 73 and connected to the sticky roller 6. The lifting assembly 75 is used to adjust the height of the sticky roller 6. Adjusting the height of the sticky roller 6 can control the distance between the sticky roller 6 and the optical film, ensuring that the sticky roller 6 and the optical film are kept within an appropriate distance range, thereby improving the dust absorption effect.

[0036] like Figure 1 As shown, the film conveyor belt 2 further includes a driving roller 21, a driven roller 22, and a plurality of transmission belts 23. The driving roller 21 is located in the middle of the frame 1, and the driven roller 22 is located at the end of the frame 1. The driving roller 21 and the driven roller 22 are connected by a plurality of transmission belts 23. The transmission belts 23 are used to convey the optical film. When the driving roller 21 rotates, the transmission belts 23 can be driven to rotate in a circular manner, thereby realizing the loading and unloading of the optical film. It should be noted that the driving roller 21 and the driven roller 22 are provided with limit grooves to prevent the transmission belts 23 from lateral deviation.

[0037] like Figure 2As shown, further, the linkage drive mechanism 5 includes a drive motor 51, a driving gear 52, a first gear 53, a transition gear 54 and a second gear 55. The drive motor 51 is arranged on the side wall of the support seat 10, and the output shaft of the drive motor 51 is connected to the driving gear 52. The first gear 53 is connected to the end of the lower roller 42, the driving gear 52 is meshed with the first gear 53, and the second gear 55 is connected to the end of the active roller 21. The second gear 55 is meshed with the driving gear 52 through the transition gear 54. With this arrangement, when the drive motor 51 is running, the first gear 53 and the second gear 55 can be driven to rotate at the same time through the driving gear 52, thereby realizing the synchronous rotation of the lower roller 42 and the film conveyor belt 2, so that the optical film maintains a steady speed during the conveying process.

[0038] like Figure 3 As shown, further, the number of the upper rollers 41 and the lower rollers 42 are both two. Such an arrangement can provide a more stable clamping force for the optical film, so that the optical film can be smoothly transported and avoid deviation.

[0039] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
