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

Abstract

The invention provides a processing method of a light guide plate with a protective film, processing equipment and the light guide plate thereof. The light guide plate has a main body, a first protective film and a second protective film, the first protective film is covered on the upper surface of the main body, and the second The second protective film is covered on the lower surface of the main body. A first corner of the upper surface is processed by laser to form a first peeling part, and the first peeling part forms a partly connected state due to the second protective film and part of the main body. Then flip the light guide plate to make the lower surface upward, and laser process a second corner of the lower surface to form a second peeling part. The second peeling part is in a partially connected state due to the first protective film and part of the body. Thus, peeling off the first peeling part removes the second protective film and forms a first positioning gap in the body, peels off the second peeling part to remove the first protective film and forms a second positioning gap in the body, and It is convenient to tear off the protective film and assemble to form a backlight module.

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
