Abstract

The invention provides a light guide sheet cutting mechanism. The mechanism comprises two bilaterally symmetrical loading platforms and two left and right symmetrical blade assemblies; each loading platform comprises a base, a blade holder capable of moving left and right, a fixed plate fixed on the base, and a compression spring connected between the blade holder and the fixed plate; the upper surface of the blade holder is a horizontal plane, the side face, facing the other blade holder, of the blade holder is a vertical plane, the vertical planes of the two knife holders are parallel to each other; each blade assemblies comprises a blade, a connecting seat arranged on one side of the blade back to the other blade component, a tension spring connected between the blade and the connectingseat, and a sliding rod arranged on the connecting seat in a sliding manner; one end of the sliding rod penetrates through the tension spring and is fixedly connected with the blade, and the connecting seat can move left and right. The cutting mechanism which is used for carrying out light guide sheet cutting is high in working efficiency, low in the risk, the positioning is accurate, and edge cutting fuzzing, burr or burr can be avoided.

Description

Technical field[0001]The invention relates to the technical field of light guide sheet production, in particular to a light guide sheet cutting mechanism.Background technique[0002]The light guide sheet is an important part of the backlight source of the liquid crystal display. It is used to diffuse the light emitted by the LED lamp in the backlight source to various angles. The light guide sheet is generally an acrylic / PC board.[0003]The light guide sheet is generally produced by injection molding, such asFigure 4 As shown, the product obtained after opening the mold (hereinafter referred to as the light guide sheet 90 to be cut) includes four light guide sheets 1', an H-shaped connecting portion 2'connected between the four light guide sheets 1', and The injection port rod 3'connected with the H-shaped connecting portion 2'; wherein the H-shaped connecting portion 2'is formed by cooling the material remaining in the runner in the mold, and the injection port rod 3'is cooled by the ...
