Glass corner image acquisition device and system

Abstract

The invention relates to a glass edge angle image collecting device and system, which are used for collecting an image of a ground edge of glass transmitted on a rubber roll production line; the device comprises a first light source, a second light source, a reflection mirror surface, a detection sensor and a camera group; the detection sensor is arranged at a preset position of the rubber roll production line and used for generating a trigger signal when the ground edge of the glass on the rubber roll production line is transmitted to the preset position; the first light source, the second light source and the camera group are positioned above a rubber roll of the rubber roll production line and connected with the detection sensor; the reflection mirror is positioned below a transmission plane of the rubber roll production line; when the detection sensor detects the trigger signal, the first light source, the second light source and the camera group begin working, the first light source and the second light source are used for performing light compensation on the ground edge of the glass from different angles, and the camera group is used for collecting the image of the ground edge of the glass. The glass edge angle image collecting device and system are more convenient to mount, and mounting and subsequent maintaining costs are reduced.

Description

technical field [0001] The present disclosure relates to the field of glass edge detection, in particular to a glass edge image acquisition device and system. Background technique [0002] Photovoltaic glass is widely used as protective glass for solar panels. The corners of photovoltaic glass need to be edging. The quality requirements for edging of photovoltaic glass corners are very strict. Usually, it is required that the size of defects such as bottom leaks, burst corners, burst edges, and burnt edges on glass corner edging should not be greater than 0.5mm , There are also certain requirements for the chamfering size of glass corners. In order to ensure the production efficiency and detection efficiency of photovoltaic glass, machine vision is usually used to detect photovoltaic glass in the process of conveying online. [0003] During the production of photovoltaic glass in the factory, photovoltaic glass is usually conveyed from one process to the next on the rubber...

AI Technical Summary

Problems solved by technology

Since the edging of the glass is an arc edge and is not on the same plane, in order to complete the detection of the glass edging, it is necessary to set up multiple sets of imaging systems in different directions of the glass edging for detection, which makes the rubber roller production line Imaging systems are installed above and below the rubber rollers. Limited by the space below the rubber roller production line, there are certain restrictions on the volume and working distance of the imaging system required to be installed. Not only is it inconvenient to install, but also the installation cost and follow-up high maintenance cost
