Laminating machine for light guide plate

Abstract

The invention relates to the technical field of light guide plate film laminating, in particular to a light guide plate film laminating machine which comprises a film laminating machine body, a reel is rotatably mounted at the upper end of the film laminating machine body, a box is fixedly mounted at the upper end of the film laminating machine body, and the box is located at the rear end of the reel; a pressurizing mechanism is movably arranged in the box body; the pressurizing mechanism can uniformly pressurize a film, so that the film laminating effect of the light guide plate is better, air can be injected into the box body under the cooperation of the pressurizing mechanism and the control mechanism, the air pressure in the box body is increased, uniform pressurizing on the film and the light guide plate is facilitated, the situation that local pressure is too large is avoided, and the laminating effect of the light guide plate is improved. According to the light guide plate pressurizing device, the compressed air in the box body can be heated through friction heat generation under the cooperation of the heating mechanism while pressurizing is conducted, the film and the light guide plate can be tightly attached together in a pressurizing and heating mode, and the film and the light guide plate can be heated and pressed more evenly in the mode.

Description

technical field [0001] The invention relates to the technical field of light guide plate laminating, in particular to a light guide plate laminating machine. Background technique [0002] The light guide plate is made of optical grade acrylic / PC sheet, and then uses high-tech materials with extremely high refractive index and no light absorption, and uses laser engraving, V-shaped cross grid engraving, and UV screen printing technology on the bottom surface of the optical grade acrylic sheet. Print light guide points. When the light guide plate is covered with a film, a rubber roller and a heating roller are generally pressed together, so that the film can be adhered to the surface of the light guide plate. [0003] When the existing light guide plate is coated by heating the roller, the roller is prone to be heated unevenly, resulting in uneven heating of the film during the coating process, thereby affecting the coating effect of the light guide plate, making the light gu...

AI Technical Summary

Problems solved by technology

[0003] When the existing light guide plate is coated with a heating roller, the roller is prone to uneven heating, resulting in uneven heating of the film during film coating, thereby affecting the coating effect on the light guide plate, making the light guide plate and the film easy to Damage occurs, which increases the cost of the LGP coating
