Photoelectric detector array-based glass shape detection system

Abstract

A photoelectric detector array-based glass shape detection system comprises a heating furnace, a glass-loading table, a toughening cooling section, a glass-unloading table, a control system and a light source, the heating furnace is used for toughening glass, the glass-loading table, the toughening cooling section and the glass-unloading table are arranged on both sides of the heating furnace, the control system is used for controlling the operation process of the toughening furnace, a detector which is used for receiving light intensity distribution information is also arranged under a roller conveying mechanism, and comprises a case, the front end of the case is provided with a light attenuation window, a collimator is arranged behind the light attenuation window, photosensitive units which are used for receiving and converting light intensity information into an electric signal are arranged behind the collimator, the detector can transmit the received shape image signal of detected glass to the control system, and the shape image signal is displayed. In the photoelectric detector array-based glass shape detection system, the light attenuation window can prevent the affection of environmental light, the collimator can effectively block the passing environmental stray light, the transmitted light can be better received by the photosensitive units, consequently, the outline of the glass can be effectively detected, and the accuracy of glass shape identification is increased.

Description

technical field [0001] The invention relates to a measurement system for glass shape parameters, in particular to a glass shape detection device based on a photodetector array. 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, the measured data will also have a large error; second, the device is easily affected by ambient light during the measurement process, which will lead to inaccurate m...
