Description

Light guide plate polishing cutter

Technical Field

The utility model relates to a light guide plate polishing cutter belongs to light guide plate processing technology field.

Background

The light guide plate is formed by printing light guide points on the bottom surface of an optical acrylic plate by using laser engraving, V-shaped cross grid engraving and UV screen printing technologies by using an optical acrylic or PC plate and then using a high-tech material with extremely high reflectivity and no light absorption. The optical-grade acrylic sheet is used for absorbing the light emitted from the lamp to stay on the surface of the optical-grade acrylic sheet, when the light irradiates each light guide point, the reflected light can be diffused towards each angle, and then the reflected light is damaged and is emitted from the front surface of the light guide plate. The light guide plate can uniformly emit light through various light guide points with different densities and sizes. The reflecting sheet is used for reflecting the light exposed from the bottom surface back to the light guide plate to improve the utilization efficiency of the light, and under the condition of the same area light-emitting brightness, the light-emitting efficiency is high and the power consumption is low.

In the process of manufacturing the light guide plate, the periphery of the light guide plate needs to be polished, so that the periphery of the light guide plate is smooth, and for some light guide plates with irregular shapes, such as some light guide plates with grooves, a common polishing tool cannot be used for polishing the light guide plates, which is not beneficial to polishing the light guide plates.
