Glass geometric parameter measurement system based on linear array ultraviolet detector

Abstract

The glass geometric parameter measurement system based on the line array ultraviolet light detector, including the heating furnace, the loading table set on both sides of the heating furnace, the tempering cooling section and the unloading table, the control system, and the ultraviolet light detection mechanism. Composed of a light source for ultraviolet light and a signal collector for capturing ultraviolet light signals and converting them into usable signals, the present invention is based on the attenuation characteristics of ordinary glass to ultraviolet light, and passes through the glass through a filter window and a large-scale photodetector array. The final light intensity is detected to form a light attenuation area that matches the shape of the glass to achieve the purpose of measuring the geometric parameters of the glass; the detection mechanism in the system adopts an integrated design, which is compact in structure and easy to install. It can be installed with other processing devices Strong adaptability, and in the detection process, the detection system can effectively filter out visible light through double filtering of visible light, avoid the influence of external light changes on the system, and improve the correct rate of model identification.

Description

technical field [0001] The invention relates to a measurement system for glass geometric parameters, in particular to a glass geometric parameter measurement system based on a line array ultraviolet light detector. Background technique [0002] At present, the glass industry is gradually using light sources combined with cameras to measure the comprehensive geometric parameters of glass to achieve the purpose of monitoring in the production process. The method and equipment use a high-intensity light source to irradiate the surface of the measured glass, and the camera analyzes the relevant data by receiving the reflected light intensity signal. The disadvantages of this method are: First, the incident angle of the light during use There are special requirements for the angle of the detection surface. When there is a deviation in the setting angle, there will be a large error in the measured data; second, the equipment is easily affected by external visible light during the ...
