Method and system for polishing glass

Abstract

A system for polishing a float glass used for liquid crystal displays includes a lower unit configured to rotate a float glass to be polished, a head assembly configured to be rotatable in contact with the float glass, and a moving unit configured to move the head assembly in a horizontal direction, wherein the head assembly includes at least two heads that are rotatable, respectively.

Description

[0001] Cross references to related patent applications [0002] This application claims priority from Korean Patent Application No. 10-2009-0095706 filed in the Republic of Korea on October 8, 2009, the entire content of the title application being incorporated herein by reference in its entirety. technical field [0003] The present invention relates to systems and methods for polishing float glass, and more particularly, to systems and methods for polishing float glass for liquid crystal displays. Background technique [0004] In general, it is very important that the flatness of the glass (or glass panel) used for the liquid crystal display is maintained at a certain level to accurately represent the image of the liquid crystal display area. Therefore, fine waviness or unevenness present on the surface of the flat glass formed in the float form should be removed. [0005] This glass polishing method can be classified into so-called "Oscar" type polishing, in which glasse...

[0010] Accordingly, the present invention is directed to providing systems and methods for polishing float glass that improve overall polishing uniformity by minimizing the variance in polish at different radii of the upper part due to As the size of the polishing system becomes larger and larger to accommodate the increasing trend of float glass size, the different line speeds at different radii of the rotating upper part lead to
