Abstract

The invention discloses a polarizer attaching device for a liquid crystal display. The polarizer attaching device comprises a base, an attaching platform, an adsorption plate and a compression roller, wherein a first vacuum adsorption hole, a second vacuum adsorption hole and a third vacuum adsorption hole are formed in the adsorption plate; the compression roller is arranged on the base; polarizers can fall in sequence to cover a glass substrate, and the compression roller is utilized for laminating the polarizers with the glass substrate, so that the generation of bubbles is effectively avoided; position sensors are arranged in the adsorption plate and the attaching platform, so that the position information of the adsorption plate and the attaching platform can be obtained; the transverse motion of the adsorption plate is realized by controlling a sliding support to slide on a first driving device, the longitudinal motion of the adsorption plate is realized by controlling a cylinder to slide on a second driving device, and the up-and-down motion of the adsorption plate is realized by controlling the piston rod of the cylinder, so that accurate positioning between the adsorption plate and the attaching platform realizes correct attaching of the polarizers and the glass substrate; the device is simple in structure, good in patch quality and high in positioning accuracy.

Description

Technical field: [0001] The invention belongs to the technical field of liquid crystal display equipment, and in particular relates to a polarizer attaching device of a liquid crystal display. 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. As the thickness of the liquid crystal display becomes thinner and thinner, the thickness of the liquid crystal display panel becomes thinner and thinner, and the size of the liquid crystal display ...
