Abstract

The invention relates to a hot rolling method of a light guide plate. The method comprises steps that a heat conduction medium is heated through a heater and is guided into pressing rollers of a hot rolling device so as to enable the pressing rollers to be heated; the light guide plate is conveyed to the hot rolling device through a conveying belt, and before the light guide plate is conveyed to the hot rolling device, the light guide plate is fixed through a clamp from the bottom of the light guide plate, and then the light guide plate is conveyed to the hot rolling device; the two oppositely-arranged pressing rollers of the hot rolling device carry out hot rolling on the surface of the light guide plate; and a pressure value of the surfaces of the pressing rollers is obtained, and according to the pressure value of the surfaces of the pressing rollers, the distance between the two pressing rollers is adjusted in real time, and therefore the pressure on the surface of the light guide plate is adjusted. According to the hot rolling method, the surface temperature distribution of the pressing rollers is more uniform, pressing on the surface of the light guide plate is more balanced, the number of bad points on the surface of the light guide plate is effectively reduced, bending generated in the hot rolling process of the light guide plate is effectively avoided, and the product yield is greatly improved.

Description

technical field [0001] The invention relates to the technical field of light guide plate processing, in particular to a hot rolling method for light guide plates. Background technique [0002] The light guide plate is an optical grade acrylic / PC board, which has the characteristics of extremely high reflectivity and no light absorption. It is widely used in LCD and LED displays. It uses optical grade acrylic board to absorb the light emitted from the lamp. When When the light hits each light guide point, the reflected light will spread to various angles, and then be emitted from the front of the light guide plate. Through various light guide points of different densities and sizes, the light guide plate can be made to emit light evenly, realizing the conversion of line light sources for the surface light source. [0003] The existing processing and molding methods of light guide plates mainly include extrusion type and injection type. The principle of injection type is that...
