Spacer paper detection method and device

Abstract

The invention relates to a spacer paper detection method and device. The method comprises the following steps: respectively acquiring a first distance from each distance measuring unit in a pluralityof distance measuring units to a glass substrate at a preset moment; and at least according to the plurality of first distances, determining whether an interval paper wrinkle phenomenon exists or not.Through the above technical scheme, due to the fact that the distance measuring unit can detect the distance from the distance measuring unit to the glass substrate in real time and send the distanceto the controller, the controller can determine whether the spacer paper wrinkles or not in real time, the real-time performance of spacer paper detection is guaranteed, the problem that time and labor are wasted in the subsequent tracing process is avoided, and the production efficiency is improved. Moreover, the number of the distance measuring units is multiple, and the projection points of any two distance measuring units on the glass substrate are not overlapped, so that the distances from the distance measuring units to different position points on the glass substrate can be measured, and the detection accuracy and reliability are ensured.

Description

technical field [0001] The present disclosure relates to the field of manufacturing and processing of glass substrates, in particular to a method and device for detecting spacer paper. Background technique [0002] During the packaging process of glass substrates, a piece of spacer paper larger than the size of the glass substrates needs to be placed between every two glass substrates to avoid direct contact between the two glass substrates. In the related technology, the robot for picking and placing the spacer paper and the robot for picking up and placing the glass substrate alternately place the spacer paper and the glass substrate on the packaging platform. Because the size of the spacer paper is too large, the spacer paper is easily damaged during the moving process. The shape changes due to the effect of air resistance, resulting in wrinkles. [0003] If the spacer paper is wrinkled, there will be no spacer paper between adjacent glass substrates at the part where th...

Problems solved by technology

In the related technology, the robot for picking and placing the spacer paper and the robot for picking up and placing the glass substrate alternately place the spacer paper and the glass substrate on the packaging platform. Because the size of the spacer paper is too large, the spacer paper is easily damaged during the moving process. Form changes due to air resistance, resulting in wrinkles

[0003] If the spacer paper is wrinkled, there will be no spacer paper between adjacent glass substrates in the folded parts, resulting in poor packaging and affecting product quality.

Due to the high speed of automated production, if the gap paper wrinkles are not found in time, it will not only take time and effort in the follow-up traceability process, but also affect production efficiency
