Problems solved by technology

However, since the automatic polarizer attaching machine cannot detect the cutting (CUT) error of the glass substrate and the polarizer, it is easy to mistakenly attach the glass substrate and the polarizer (the glass substrate or / and the polarizer has a cutting error) by mistake. Error) are attached together, resulting in low attachment accuracy of polarizers and high product defect rate

Abstract

The invention discloses an attaching method of a polaroid. The method comprises following steps: putting a substrate into an attaching machine for the polaroid; determining whether the substrate is up to the standard through the attaching machine for the polaroid or not; putting the polaroid into the attaching machine for the polaroid; determining whether the polaroid is up to the standard or not through the attaching machine for the polaroid; and attaching the polaroid to the substrate if the substrate and the polaroid are up to the standard. The attaching method of the polaroid is high in attaching precision. The invention further discloses the attaching method of the polaroid.

Description

technical field [0001] The invention relates to the technical field of attaching polarizers, in particular to a method for attaching polarizers and a machine for attaching polarizers. Background technique [0002] Polarizer is an optical film composed of multi-layer polymer materials with the function of generating polarized light. The polarizer converts non-polarized natural light into polarized light, and allows the light perpendicular to the electric field to pass through. The liquid crystal display panel can display images normally, which is an indispensable part of liquid crystal display imaging. In the back-end manufacturing process of liquid crystal displays, polarizers need to be attached to glass substrates that have been attached with flexible circuit boards. [0003] The existing automatic polarizer attaching machine usually aligns the glass substrate and the polarizer to be attached first, and then moves the polarizer through conversion and attaches it to the gl...
