Self-cleaning polaroid attaching device

Abstract

Provided is a self-cleaning polaroid attaching device. The self-cleaning polaroid attaching device comprises an upper platform, a lower platform and a roller assembly. The lower surface of the upper platform is used for placing a polaroid. A negative-pressure hole communicating with the lower surface is arranged in the upper platform. The upper surface of the lower platform is used for placing a display panel. The roller assembly comprises an attaching roller, a lower pressure roller, a belt delivery roller and a belt receiving roller. The upper platform is rotatably connected with the attaching roller. The lower pressure roller is arranged above the attaching roller. Two sides of the lower pressure roller are respectively equipped with the belt delivery roller and the belt receiving roller. A dust-sticking paper strip penetrates between the attaching roller and the lower pressure roller. Two sides of the dust-sticking paper strip are fixedly connected with the belt delivery roller andthe belt receiving roller. The roller assembly moves along the upper surface of the lower platform. Therefore, the attaching roller rolls while the Polaroid is attached to the display panel and usedfor cleaning the outer surface of the polaroid. The polaroid is attached to the display panel while dust on the outer surface of the polaroid is eliminated. A purging mechanism purges the polaroid andan inner surface attached to the display panel in order to ensure that there is no dust during an attachment process.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to a self-cleaning polarizer bonding device. Background technique [0002] The clarity of the liquid crystal display is one of the important indicators to evaluate its display effect. Among them, improper handling of the process of "attaching the polarizer to the display panel" in its production process is one of the main factors causing low clarity, as follows: During the process of attaching the polarizer to the display panel, Polarizers need to be attached to both sides of the display panel respectively. On the surface of the polarizer, the surface of the display panel, and the platform where the polarizer is transported and the display panel is in contact with it, there will be some dust, impurities and other pollutants attached to it, which reduces the cleanliness of the production process, and the display panel is covered with dust. It directly affects the display ef...

AI Technical Summary

Problems solved by technology

On the surface of the polarizer, the surface of the display panel, and the platform where the polarizer is transported and the display panel is in contact with it, there will be some dust, impurities and other pollutants attached to it, which reduces the cleanliness of the production process, and the display panel is covered with dust. directly affect the display effect of the display

There are impurities on the display panel, which will cause exceptions to the display panel and damage to the polarizer during the attaching process of the polarizer, resulting in defective products during the production process. In serious cases, the polarizer and display panel will be scrapped directly

In the existing production process, the surface of the product and the contact platform are not cleaned, or a single cleaning device is repeatedly cleaned, resulting in low cleanliness in the production process, which seriously affects the imaging quality of the LCD

[0003] Therefore, it is necessary to clean up the dust in time during the bonding process of the polarizer and the display panel. There is no corresponding technical solution for this requirement.
