Abstract

The invention discloses a device and method for regulating warping of a glass plate. The device comprises overflow down-drawing forming equipment. Glass plate cutting equipment is arranged at the rear end of the overflow down-drawing forming equipment, and a traction roller is arranged between the overflow down-drawing forming equipment and the glass plate cutting equipment. The holding force of the traction roller to a glass plate is increased, in an overflow down-drawing method, the clamping force of the traction roller is greatly affected by friction force between the surface of a boss and the glass plate, the friction coefficient of the surface of the boss is increased, friction force is increased, therefore, the glass plate runs stably through the method of increasing the clamping force, and warping badness caused by back-and-forth running of the glass plate is eliminated.

Description

technical field [0001] The invention belongs to the field of glass substrate manufacturing, and in particular relates to a device and method for adjusting the warping of a glass plate. Background technique [0002] Existing glass plates (with a thickness between 0.3 mm and 1.4 mm) mainly refer to substrate glass used in flat panel display technology, which is one of the key components of flat panel displays. For many display devices, the surface flatness of the glass used in the panel must be within 150 microns, and any fluctuations in warp in the glass can negatively affect the quality of the display out of shape. [0003] For example, an LCD display includes a layer of liquid crystal material connected to a glass substrate, and transistors (TFTs), which are arranged in a patterned array to align liquid crystal molecules in a desired manner. [0004] Therefore, any change in the warping of the glass substrate will lead to changes in the spacing between transistors and pix...
