Device and method for measuring cutting quality of overflow-forming glass

Abstract

The invention discloses a measuring device and a measuring method for the cutting quality of overflow-formed glass. By setting a scribing device and a colorless and transparent measuring reference platform, a horizontal reference line and a vertical reference line perpendicular to each other are set on the measurement reference platform. , as the reference line for placing the sample to be tested, and then use two horizontal linear guides set parallel to the horizontal reference line and a vertical linear guide set parallel to the vertical reference line on the scribing device. There is a scribing board, using the relative sliding between the vertical linear guide rail and the horizontal linear guide rail and the sliding of the scribing board relative to the vertical linear guide rail, the sample to be tested is placed on the measurement reference platform, and the scribing board is used on the measurement reference platform. Draw a line along the edge of the sample to be tested on the platform, so that the distance between the sample to be tested and the horizontal reference line and vertical reference line can be obtained, so as to realize the efficient, convenient and intuitive detection of the degree of deformation of the glass cutting shape and the edge deformation trend.

Description

technical field [0001] The invention belongs to the technical field of glass manufacturing and processing, and in particular relates to a measuring device and method for overflow forming glass cutting quality. Background technique [0002] High-end cover glass substrates for overmolded touch display protection are typically made of aluminosilicate glass. [0003] The glass substrate produced by the overflow molding method has good quality and is mostly used in the production and processing of high-end liquid crystal glass substrates and cover glass substrates for touch screen protection. The temperature control in the glass forming process is extremely important, which will directly affect the glass quality such as thickness and stress. At the same time, the forming and cutting of a single glass is also critical. After the glass is formed, it forms a continuous curtain-like glass ribbon, which must be cut to form a standard rectangular single piece of glass. However, when t...

Problems solved by technology

[0007] In the process of glass cutting into plates, multiple actions such as cross-cutting, robot grabbing / transferring, conveying trolley clamping, hanging transmission, and longitudinal cutting, etc., the coordination and accuracy of each action during this process will be improved. The cutting shape is bad, resulting in the geometric deformation of the finished glass, such as: parallelogram, trapezoidal deformation, etc., and then forming bad angles, straightness, parallelism, etc.

[0008] Although the traditional right angle tester can measure the right angle, it cannot intuitively reflect the edge deformation shape and deformation size related to the processing action; although the imager can realize this function, but for large-size glass substrates, Expensive equipment and poor practicability
