Problems solved by technology

However, the cutting of the optical film will produce redundant scraps. If the transmission route of the scraps is not properly planned, it may interfere with the subsequent process of the optical film and even cause damage to the optical film.

Abstract

The invention provides a cutting and winding method for an optical film, and a cutting knife adopted by the method. The cutting and winding method for the optical film comprises the following steps: (A) and a feeding unit is used for providing an optical film; (B) the optical film is conveyed to a cutting unit, and the cutting unit comprises a cutting knife, wherein the cutting knife cuts the optical film into a main body part and an edge material part, wherein the main body part comprises an optical membrane, and the rim charge part is separated from each other; (C) after the step (b), the optical diaphragm is conveyed to a finished product collecting position along a first direction through a conveying belt, and enabling the rim charge parts to be transmitted to a winding unit in a second direction, the included angle between the first direction and the second direction ranges from 0 degrees to 100 degrees, the process efficiency is effectively improved, and the needed labor cost isreduced.

Description

technical field [0001] The invention relates to a cutting and winding method of an optical film, and in particular to a winding method of the edge material produced by cutting the optical film. Background technique [0002] Polarizers are optical components widely used in liquid crystal displays. With the increasing application of liquid crystal displays, such as mobile phones and wearable devices, the requirements for the quality of polarizers are also getting higher and higher. [0003] After the polarizer is manufactured, it is usually cut to be attached to displays of various sizes. In addition, since the incoming size of various optical film materials differs greatly from the required size of the finished product, the optical film material is also cut during the production process of the polarizing plate to adjust the size of the film material. However, the cutting of the optical film will produce redundant scraps. If the transmission route of the scraps is not properl...
