[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 intensitysignal. 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

Embodiment 1
[0028] Such as figure 2 As shown, first determine the coordinates of each photoelectric sensor in the mobile measuring ruler 1 and the fixed measuring ruler 2, for example: when 10 photoelectric sensors are evenly distributed on the moving measuring ruler, A represents the moving ruler, and the coordinates of each point on the moving ruler, The unit is 0.1mm, followed by A1(0,0), A2(1983,0), A3(3985,0), A4(5991,0), A5(7987,0), A6(9992,0), A7( 11981,0), A8(13987,0), A9(15951,0), A10(17979,0);
[0029] Determine the coordinates of the sensor on the fixed measuring ruler, S represents the fixed ruler, take setting 11 as an example, the order is: S1(0,920), S2(2000,920), S3(4000,920), S4(6000,920), S5(8000,920), S6(10000,920), S7(12000,920), S8(14000,920), S9(16000,920), S10(18000,920), S11(20000,920);
[0030] It can be seen from the above coordinates that the coordinates of the first photoelectric sensor on the mobile measuring ruler are set to (0,0) to facilitate subsequent ...
Embodiment 2
[0054] Such as image 3 As shown, first determine the coordinates of each photoelectric sensor in the mobile measuring ruler 1 and the fixed measuring ruler 2. For example: set 10 photoelectric sensors evenly distributed on the moving measuring ruler, and the coordinates of each point on the moving ruler are A1(0, 0), A2(1983,0), A3(3985,0), A4(5991,0), A5(7987,0), A6(9992,0), A7(11981,0), A8(13987,0 ), A9(15951,0), A10(17979,0);
[0055] Determine the coordinates of the sensor on the fixed measuring ruler, S represents the fixed ruler, take setting 11 as an example, the order is: S1(0,920), S2(2000,920), S3(4000,920), S4(6000,920), S5(8000,920), S6(10000,920), S7(12000,920), S8(14000,920), S9(16000,920), S10(18000,920), S11(20000,920);
[0056] The same as the first embodiment is that the position of each photoelectric head needs to be checked before the measurement. After the check, the detection is started. We also transfer some data from the computer to explain: the list...

Abstract
A method for measuring geometric parameters of glass, using photoelectric sensors distributed on a fixed measuring ruler across the glass conveying passage to sample the glass conveying passage at intervals, and determining the front edge of the glass and the The time difference when the rear edge passes through the fixed measuring ruler, and then use the time difference and the conveying speed of the glass to obtain the length dimension of the glass; use the photoelectric sensors distributed on the moving measuring ruler that reciprocates along the width direction of the glass conveying passage to space the glass conveying passage Sampling to derive the width dimension of the glass. The method only needs to use a fixed measuring ruler and a moving measuring ruler, and photoelectric sensors are evenly distributed on the fixed measuring ruler and the moving measuring ruler to sample the glass conveying channel at intervals, so that the geometric parameters of the glass shape can be quickly and accurately measured.
