DETAILED DESCRIPTION

[0028] The invention discloses a low active power consumption anti-reflection film, comprising a base support layer, a functional layer and a protective layer arranged in sequence. The base layer is made of PET material and has good mechanical properties, such as high strength and good toughness, and can withstand a certain degree of stretching and bending and is not easy to break. The functional layer includes a liquid crystal layer and a conductive layer arranged on both sides of the liquid crystal layer, and the conductive layer is used to provide an electric field for the liquid crystal layer. ITO conductive material is adopted, and ITO has good conductivity and high transparency, and can effectively conduct current while ensuring light transmission. The protective layer adopts TAC protective film, which is mainly used to protect the functional layer inside the anti-reflection film from damage by the external environment. An insulating layer is arranged on the side of the conductive layer away from the liquid crystal layer, and the insulating layer adopts epoxy resin. By arranging an insulating layer on the outer side of the conductive layer and coating a suitable insulating film, the electric field distribution can be more uniform, and the probability of corona discharge can be reduced, thereby reducing the power consumption of the anti-reflection film during use.

[0029] like Figures 1 to 8 As shown, the present invention discloses a low active power consumption anti-reflection film preparation device, which adopts the above anti-reflection film, and the preparation device includes an integrated scraping device and a laminating device. The integrated scraping device can be used to spray the insulating material on the surface of the conductive layer, and can also scrape it flat. The integrated scraping device is used to scrape the insulating layer on the surface of the conductive layer, and the laminating device adopts existing equipment, and is used to heat press each layer together in sequence through the laminating device to form a complete anti-reflection film.

[0030] In this embodiment, the integrated scraping device includes a moving frame 1, a longitudinal displacement driving device for driving the moving frame 1 to move longitudinally, and a scraping seat plate 2 installed at the end of the moving frame 1. The longitudinal displacement driving device can use a conventional mechanical arm or a linear guide rail, and the longitudinal displacement driving device can drive the moving frame 1 to move longitudinally, so as to scrape and coat various longitudinal positions on the conductive layer. As needed, the mechanical arm can be displaced in the lateral direction to increase the scraping area.

[0031] The scraper seat plate 2 is arranged in the transverse direction, with the moving direction of the scraper seat plate 2 as the front and back, and a notch 3 is provided at the rear end of the scraper seat plate 2, and a transverse shaft rod 4 and a crossbeam 5 are arranged at the notch 3, and the shaft rod 4 is parallel to the scraper seat plate 2. A plurality of coating blocks 6 are closely arranged in the transverse direction in the notch 3, and each coating block 6 is in the shape of an elongated rectangular parallelepiped, and the middle part of the coating block 6 is hinged with the shaft rod 4, and can be deflected and displaced around the shaft rod 4. Of course, the adjacent two shaft rods 4 are closely slidably matched to avoid the infiltration of impurities.

[0032] Specifically, the coating block 6 is arranged obliquely and made of silicone or rubber material to facilitate scraping the surface of the conductive layer. The coating block 6 extends obliquely downward from one end of the scraping seat plate 2 toward the rear end of the scraping device. The lower side of the lower end of the coating block 6 forms a chamfered surface 7 to reduce damage to the conductive layer. The lower end chamfered surfaces 7 of several coating blocks 6 are combined in the horizontal direction to form a scraping area for scraping the conductive layer. The upper end of the coating block 6 is connected to the beam 5 through an elastic support member, and the elastic support member provides an elastic restoring force to ensure the smoothness of the scraping process; the present invention sets multiple coating blocks 6 on the scraper, and when one of the coating blocks 6 encounters a protrusion, it can give way in time to prevent the insulating layer of the protruding part from being scraped off, resulting in unevenness of the overall insulating layer. Therefore, the preparation device of the present invention is used to coat the insulating layer, which can improve the uniformity of the insulating layer, reduce the probability of corona discharge, and reduce the active power consumption of the anti-reflection film during use.

[0033] In this embodiment, a clearance groove 8 is provided at the upper end of the coating block 6, and the clearance groove 8 penetrates the coating block 6 as a whole. The elastic support member includes a guide shaft 9, a spring 10 and a limiter 11. The limiter 11 adopts a nut to prevent the coating block 6 from escaping from the guide shaft 9. One end of the guide shaft 9 is fixedly connected to the crossbeam 5, and the other end of the guide shaft 9 is connected to the limiter 11 after passing through the clearance groove 8. The spring 10 is sleeved on the outside of the guide shaft 9, and the two ends of the spring 10 are respectively connected to the coating block 6 and the crossbeam 5. The above method can be used to elastically support the coating block 6. It can be understood by those skilled in the art that by rotating the nut, the initial compression degree of the coating block 6 can be adjusted as needed to reduce the influence of the error on the scraping and ensure the uniformity of the scraping on the surface of the conductive layer.

[0034] In this embodiment, a support plate 12 is integrally formed at the front end of the scraper seat plate 2, a material box 13 is installed on the support plate 12, the material box 13 is filled with flowing insulating material, a spray port 14 connected to the material box 13 is formed at the bottom of the scraper seat plate 2, and a limiting component is installed on the material box 13 for limiting the coating block 6 to prevent the coating block 6 from excessive flipping.

[0035] In this embodiment, a groove 15 is provided on the upper side of the coating block 6, and the limiting assembly includes a pressure rod 16, a bent plate 17 and a telescopic device 18.

The telescopic device 18 is also hinged on the material box 13. The output end of the telescopic device 18 is connected to the middle of the bent plate 17. The telescopic device 18 is electrically connected to a protrusion sensing component through a controller. The protrusion sensing component is arranged at the front end for detecting the protrusion. When there is a protrusion on the surface of the conductive layer, the protrusion sensing component can send a signal to the controller, and the controller controls the telescopic device 18 to loosen. At this time, each coating block 6 can be enabled separately, and the device works normally. After running smoothly for a period of displacement, the controller controls the telescopic device 18 to start, and the telescopic device 18 drives the pressure rod 16 to press the coating block 6 downward to prevent the coating block 6 from turning over and ensure the stability of the working process.

[0036] In this embodiment, the protrusion sensing assembly includes a support plate 19 and a pressure sensor 20. The upper end of the support plate 19 is connected to the support plate 12 through an elastic recovery connector 21.

The pressure sensor 20 is connected to the telescopic device 18 through a controller. By setting the support plate 19 that extends forward and obliquely downward, some small protrusions or impurities remaining on it can be removed to improve the cleanliness of the surface of the conductive layer.

[0038] An outer cylinder 26 is rotatably mounted on the outer side of the center rod 25, and the outer cylinder 26 is connected to the coating base plate 2 through an adjustable support 27. A rotation control device 28 for controlling the rotation of the outer cylinder 26 is also mounted on the center rod 25.
