Rubbing carrying and conveying device and rubbing system

Abstract

The invention discloses a rubbing carrying and conveying device. The rubbing carrying and conveying device is provided with a rubbing region, wherein the rubbing region comprises a plurality of strip-shaped regions which are crossed at the center of the rubbing region. The rubbing carrying and conveying device comprises a plurality of first rollers, a plurality of second rollers and a third roller, wherein the first rollers are fixedly arranged at the rubbing region outside the strip-shaped regions; a plurality of first axes of the first rollers are parallel and form a carrying surface; the second rollers are arranged on the strip-shaped regions in the way that the second rollers can lift relative to the carrying surface; a plurality of second axes of the second rollers are parallel to the first axes; the third roller is arranged at one of the strip-shaped regions in the way that the third roller can lift relative to the carrying surface and can rotate around the center of the rubbing region. According to a rubbing system with the rubbing carrying and conveying device, a substrate can be easily and conveniently carried and conveyed to perform a rubbing process without substrate stripping operation, so that static electricity generation and accumulation can be effectively avoided, and deformation and breakage of the substrate are effectively prevented.

Description

technical field [0001] The present invention relates to the technical field of manufacturing liquid crystal display panels, and in particular to a rubbing alignment carrying and conveying device of a rubbing alignment system and a rubbing alignment system having the rubbing and aligning carrying and conveying device. Background technique [0002] In the manufacturing process of the liquid crystal display panel, in order to achieve a good rotation effect of the liquid crystal material, an alignment film (alignment layer) usually needs to be fabricated on the electrode substrate. For example, after the alignment film is coated on the electrode substrate, rubbing alignment (rubbing) process is carried out by rubbing alignment equipment, so that grooves arranged in a certain direction are formed on the surface of the alignment film due to friction, so that the liquid crystal material on the alignment film produces alignment effect. [0003] The existing friction alignment equip...

AI Technical Summary

Problems solved by technology

However, in the process of lifting the support legs to separate the electrode substrate from the friction carrier, the electrode substrate will receive a large momentary impact force, so the electrode substrate is prone to breakage

Although the existing technology can reduce the instantaneous impact on the electrode substrate by reducing the rising speed of the supporting feet to reduce the rupture of the electrode substrate, the slow rising speed of the supporting feet will lead to an increase in the production time consumed by the friction alignment process, which is not conducive to improving Productivity

On the other hand, in the process of lifting the supporting feet to peel off the electrode substrate and the friction carrier, a large amount of static electricity will be generated on the electrode substrate and the friction carrier, and the electrostatic attraction between the electrode substrate and the friction carrier will also cause the electrode substrate to Bending, deformation or even rupture, and the accumulation of static electricity on the friction carrier will lead to electrostatic breakdown of the circuits located around the alignment film on the subsequent friction alignment electrode substrate, which will affect the quality of the LCD panel and may even cause safety accidents
