Description

Technical Field

[0001] The utility model relates to the technical field of light guide plate production, in particular to a polishing device for light guide plate production. Background Art

[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 non-light absorption to print light guide points on the bottom of the optical grade acrylic sheet by laser engraving, V-shaped cross grid engraving, and UV screen printing technology. The optical grade acrylic sheet is used to absorb the light emitted from the lamp and stay on the surface of the optical grade acrylic sheet. When the light hits each light guide point, the reflected light will spread to various angles, and then destroy the reflection conditions and 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 emit light evenly.

[0003] During the production process, the light guide plate needs to be polished by a polishing device. In the prior art, the polishing plate needs to be limited on all sides during polishing, and then the light guide plate is polished by a motor-driven polishing wheel. Since the motor will vibrate during operation, the polishing wheel will vibrate synchronously, thereby causing a vibration to the light guide plate. Since the polishing plate is vibrated all around, the polishing area around it is prone to shaking, causing the light guide plate to easily shift, affecting the polishing effect.
