Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] see figure 1 , which is a flowchart of a method for repairing a light guide plate according to an embodiment of the present invention, the method for repairing a light guide plate includes the following steps:

[0020] Step S1, please also refer to figure 2 , providing a light guide plate 10 to be repaired, at least one side surface of the light guide plate 10 has scratched dents 11 . In this embodiment, the light guide plate 10 is placed horizontally, and the side surface with the indentation 11 faces upward. The material of the light guide plate 10 is polymethylmethacrylate (polymethylmethacrylate: PMMA).

[0021] Step S2, please also refer to image 3 , providing an ultraviolet (ultraviolet: UV) curing glue 20, and coating the UV curing glue 20 on the surface of the light guide plate 10 to be repaired. The UV-curable glue 20 is a water-soluble low-vis...

Abstract

A light guide plate repairing method includes the steps of providing a light guide plate to be repaired, at least one lateral surface of which is provided with scratched dents; providing UV (ultraviolet) curing glue applied to the surface, to be repaired, of the light guide plate; providing a scraper used to scrape the UV curing glue on the surface of the light guide plate and used to fill the dents of the light guide plate with the UV curing glue; providing a UV source, using the UV source to irradiate the UV curing glue on the surface of the light guide plate so as to cure the UV curing glue; providing a polisher, and using the polisher to grind and polish the surface, with the curing glue cured, of the light guide plate; and cleaning the ground and polished surface of the light guide plate. The UV curing glue is used to repair the scratched surface of the light guide plate by the light guide plate repairing method, so that defects of the scratched light guide plate can be eliminated, rejection rate of the light guide plate can be lowered and waste of raw materials of the light guide plate can be decreased.

Description

technical field [0001] The invention relates to a method for repairing a light guide plate, in particular to a method for repairing a light guide plate for repairing scratches on the surface of the light guide plate. Background technique [0002] As a precision optical component, the light guide plate has strict quality requirements. Therefore, it is necessary to avoid scratches on the surface of the light guide plate during the production process and the subsequent assembly process. Methods to prevent scratches include, for example, regularly wiping the work surface of the light guide plate production and assembly, and attaching anti-scratch stickers to the surface of the light guide plate. protective film, etc. However, the above method can only prevent scratches on the surface of the light guide plate to a certain extent. Once the surface of the light guide plate is scratched, it can only be scrapped, resulting in waste and a decrease in the yield of the light guide plat...
