Processing method and processing equipment of light guide plate with protective film and light guide plate

Abstract

The invention provides a processing method and processing equipment of a light guide plate with a protective film and the light guide plate, the light guide plate is provided with a body, a first protective film and a second protective film, the first protective film covers an upper surface of the body, and the second protective film covers a lower surface of the body. A first corner of the uppersurface is processed by laser to form a first stripping part, wherein the first stripping part forms a partial connection state due to the second protective film and part of the body; then the light guide plate is turned over to enable the lower surface to face upwards, a second corner of the lower surface is subjected to laser processing to form a second stripping part, and the second stripping part forms a partial connection state due to the first protective film and part of the body; therefore, the first stripping part is stripped to remove the second protective film and a first positioningnotch is formed in the body, and the second stripping part is stripped to remove the first protective film and a second positioning notch is formed in the body, so that the protective film is convenient to tear off and the backlight module is convenient to assemble.

Description

technical field [0001] The invention relates to the field of light guide plates, in particular to a processing method of a light guide plate with a protective film, processing equipment and the light guide plate. Background technique [0002] The light guide plate is a common optical component used to guide light, especially in the fields of display equipment and lighting. The production of the light guide plate can be manufactured in a variety of ways depending on its size or light output requirements. Regardless of the manufacturing method, in order to protect the various optical structures designed on the light guide plate and avoid damage during shipment and transportation, The light-emitting surface of the light guide plate and the surface opposite to the light-emitting surface are covered with a protective film to prevent the optical structure on the light guide plate from being scratched or damaged. After the light guide plate is manufactured, it can be packaged and ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a processing method for a light guide plate with a protective film, processing equipment and the light guide plate in order to overcome the defect that the protective film is not easy to tear off in the prior art. The special structure is formed by laser processing, so that the protective film can be completely removed, which effectively improves the defect that the protective film is not easy to remove, and after the protective film is removed, a positioning gap can be formed on the light guide plate, which greatly improves the convenience of subsequent assembly sex
