Measuring method for detecting geometric parameters of irregular glass

Abstract

The invention discloses a measuring method for detecting geometric parameters of irregular glass. The method includes the steps that firstly, a database related to shapes of the irregular glass is created, before measurement, a type of the irregular glass to be detected is selected, and sampling at intervals is conducted on a glass transfer passage by using photoelectric sensors which are distributed on a fixed measuring scale and a moving measuring scale which stretch across the glass transfer passage; data parameters of the glass in the length direction and data parameters of the glass in the width direction are obtained by sampling; the data parameters obtained by the fixed measuring scale and the moving measuring scale are extracted by a data processing unit, multiple boundary data points of the irregular glass to be detected are sought out according to the measured data, the data are processed by combining the selected type of the irregular glass selected in the database, and the geometric parameters of the irregular glass are obtained. Only the fixed measuring scale and the moving measuring scale need to be used, the sampling at intervals is conducted on the glass transfer passage by using the photoelectric sensors which are distributed on the fixed measuring scale and the moving measuring scale, and the shape geometric parameters of the glass can be measured fast and accurately.

Description

technical field [0001] The invention relates to a geometric measurement applied to glass, in particular to a measurement method for detecting geometric parameters of special-shaped glass. Background technique [0002] At present, in the glass processing industry, the tempering equipment used generally needs to be equipped with a system to detect the shape parameters of the glass to be tempered, so as to achieve the purpose of monitoring during the production process. Conventional methods and equipment use high-intensity light sources to irradiate the surface of the glass to be tested , the camera analyzes the relevant data by receiving the reflected light intensity signal. The disadvantages of this method are: First, there are special requirements for the incident angle of light and the angle of the detection surface during use. When there is a deviation in the installation angle , the measured data also has large errors, so the installation and debugging are more cumbersome...

[0002] At present, in the glass processing industry, the tempering equipment used generally needs to be equipped with a system to detect the shape parameters of the glass to be tempered, so as to achieve the purpose of monitoring during the production process. Conventional methods and equipment use high-intensity light sources to irradiate the surface of the glass to be tested , the camera analyzes the relevant data by receiving the reflected light intensity signal. The disadvantages of this method are: First, there are special requirements for the incident angle of light and the angle of the detection surface during use. When there is a deviation in the installation angle , the measured data also has large errors, so installation and debugging are more cumbersome; second, the measurement process is easily affected by ambient light, which will lead to inaccurate measured data
