Problems solved by technology

[0003] After the glass is baked and formed, it needs to be tested for its spherical surface. In the prior art, the glass is turned over and tilted on the shelf, and then the measuring rod is manually placed on the glass, and the glass is measured by a dial indicator or a ruler. Spherical detection, the problems caused by this detection method are: 1. The position of manual detection is judged by eyes, and the deviation is large
The test results of different people are quite different; 2. With the increase of glass varieties, it is not easy to remember the test value and tolerance value manually, and it is impossible to feed back to the main control in real time for product parameter adjustment
3. With the increase of product varieties, the number of detection points that need to be increased is greatly increased, the efficiency of manual detection is low, the beat is slow, and it cannot keep up with the production beat

Embodiment 1

[0080] Such as Figure 9 As shown, when testing the overall spherical surface of the glass plate 100, specifically the detection points M1 to M9, the specific steps are: find point C1; shift point C1 to the X-axis direction by 100 mm to find point C3; place point C3 on the YZ plane Project to the short-arc side 1002 to obtain point C4; project point C4 along the Y axis to the long-arc side 1001 to obtain point C5, adjust the height of point C4 and point C5 to obtain line G3; find point C5 and point C4 The midpoint of the connecting line, and project it onto the surface of the glass plate 100 along the Z-axis direction to obtain point M8; shift the point C4 forward by 100mm along the Y-axis direction, and project it onto the glass plate 100 along the Z-axis direction On the surface, point M7 is obtained; point C5 is reversely offset by 100mm along the Y-axis direction, and projected onto the surface of the glass plate 100 along the Z-axis direction, and point M9 is obtained; th...

Embodiment 2

[0082] Such as Figure 9As shown, when detecting the H region of the glass plate 100, the point C6 can be obtained by shifting C1 to the X-axis direction by 200 to 300 mm in the positive direction, and the points M23, M24, and M30 can be obtained in the same way as in Example 1. M30 is offset by 100mm in the positive and negative directions of the X-axis direction and projected to obtain points M27 and M33. Points M27, M30 and point M33 are offset by 150mm in the Y-axis direction and projected to obtain points M32, point M29 and point M26. In the same way, point M31, point M28, and point M25 can also be obtained; since then, nine measurement points in the H area have been determined, and point M12 to point M22 can be obtained in the same way.

Embodiment 3

[0084] Such as Figure 9 As mentioned above, when detecting the N area of ​​the comparative version, after the point M4 is obtained in the first embodiment, the point M10 can be obtained by shifting it positively along the Y-axis direction by 50, and the point M11 can also be obtained in the same way. It can also be calculated by The difference between the measured value obtained at point M4 and the measured value obtained at point M11 is compared with the preset value to determine whether the arc of the glass plate 100 in the N region is qualified.

Abstract

The invention relates to a glass spherical surface detection device, which has a detection station, and also includes: a moving device, arranged above the detection station; a visual device, used to photograph the glass plate on the detection station, and obtain the recorded glass plate The image information of the contour image; the control device is used to receive the image information, construct the position coordinate map from the image information, and obtain the position information of a plurality of measurement points from the position coordinate map; the detection device has a reference position, and the detection device is used to detect and measure The distance between the point and the reference position; the mobile device can drive the detection device to measure each measurement point according to the position information of multiple measurement points provided by the control device. The disadvantage of large value has the advantage of high detection accuracy.

Description

technical field [0001] The invention relates to glass detection equipment, in particular to a glass spherical surface detection equipment. [0002] The invention also relates to a glass spherical surface detection method applied to the glass spherical surface detection equipment. Background technique [0003] After the glass is baked and formed, it needs to be tested for its spherical surface. In the prior art, the glass is turned over and tilted on the shelf, and then the measuring rod is manually placed on the glass, and the glass is measured by a dial indicator or a ruler. For spherical detection, the problems caused by this detection method are: 1. The position of manual detection is judged by eyes, and the deviation is relatively large. The test results of different people are quite different; 2. With the increase of glass varieties, it is not easy to remember the test value and tolerance value manually, and it is impossible to feed back to the main control in real tim...
