Surface scratch repair process of glass light guide plate

Abstract

The invention provides a surface scratch repair process of a glass light guide plate. The process comprises the following steps: (1) cleaning: a light guide plate with a light outlet surface scratched in the machining process is cleaned; (2) checking and positioning: the scratched place on the light outlet surface of the light guide plate is accurately positioned through detection setting, and is marked; (3) repair: a repair mixture is splashed at the scratched part; the scratched part is polished by a grinding wheel; the repair mixture is formed by mixing polishing powder, epoxy resin powder and inorganic silica gel; and the mixing ratio of the polishing powder, the epoxy resin powder and the inorganic silica gel is 7: 1: 2; and (4) the light guide plate is cleaned again after the step (3), and is dried to obtain a finished product. The process has the following beneficial effects: the process modifies the scratched surface of the glass light guide plate, guarantees no influence on the light guide quality of the light guide plate due to scratching, protects the environment, is simple in repair flow, saves the production cost for enterprises, and reduces the loss.

Description

technical field [0001] The invention relates to the technical field of repairing scratches on a glass light guide plate, in particular to a process for repairing scratches on the surface of a glass light guide plate. Background technique [0002] In the prior art, it is very common to use glass instead of acrylic to make light guide plates. During the production and processing of the glass light guide plate, due to carelessness in handling or transferring the light guide plate products, it is easy to scratch the glass light guide plate. Once the light emitting surface of the glass light guide plate is scratched, the light output quality of the light guide plate will be affected. In the prior art, such defective products are generally scrapped, which is not environmentally friendly and increases the production cost of the enterprise. Contents of the invention [0003] Based on this, the present invention provides a scratch repair process for the surface of the glass light ...
