Forming equipment capable of adjusting glass substrate thickness distribution uniformity and method for adjusting glass substrate thickness distribution uniformity by adopting forming equipment

Abstract

The invention provides forming equipment capable of adjusting glass substrate thickness distribution uniformity and a method for adjusting the glass substrate thickness distribution uniformity by adopting the forming equipment and belongs to the field of manufacturing of glass substrates. Cooling sockets are formed in the side wall of the forming equipment and are located between an overflow groove and a traction roll assembly of the forming equipment; the forming equipment further comprises cooling insert pipes which are of enclosed hollow-out pipes, tail ends of the cooling insert pipes are connected with coolant outlet pipelines, and coolant sleeves are arranged in the cooling insert pipes; tail ends of the coolant sleeves are fixed to the tail ends of the cooling insert pipes and are connected with coolant inlet pipelines; front ends of the coolant sleeves are communicated with front end of the cooling insert pipes; the cooling insert pipes can be inserted in the cooling sockets to be matched with the same, and the distance between parts of the cooling insert pipes, extending to the forming equipment and a glass substrate is 3-15cm. By the arrangement, the glass substrate thickness distribution uniformity can be adjusted, thinner places on the glass substrate can be thickened, and thicker places on the glass substrate can be thinned.

Description

technical field [0001] The invention belongs to the field of glass substrate manufacturing, and relates to a molding device and method capable of adjusting the thickness distribution uniformity of a glass plate. Background technique [0002] The glass plate (with a thickness between 0.3 mm and 1.4 mm) in this application mainly refers to the 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 50 microns, and any thickness fluctuations in the glass can negatively impact the quality of the display. [0003] For example, any change in the thickness of the glass substrate in the LCD panel will lead to changes in the spacing between transistors and pixels, which will directly affect the electric field and pixels of the display, making the gray scale and color of the display uneven, resulting in defects such as bright spots.

However, this device has limitations. Its shortcoming is that the cold place of the glass plate can only be thickened by cooling, and the thicker place cannot be thinned.
