Embodiment Construction

[0037] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] The embodiment of the present invention proposes a scheme for detecting shielding glass defects by combining illumination with multiple light sources.

[0039] The composition of the uniform background light illumination shielding glass defect detection system is as follows: figure 1 As shown, the shielding glass 6 is fixed on the bracket 7 of the two-dimensional electric workbench 8, a white highlight background light 9 is placed under the workbench for vertical illumination, and a high-resolution industrial area scan camera 4 and a high-resolution The industrial lens 5 collects images and transmits them to the computer 1. At the same time, the computer is connected to a two-axis controller 2 and a light source controller 3. The two-axis controller 2 controls the movement of the electric workbench 8, and the light source controller 2 controls the...

Abstract

The invention relates to a method for automatically detecting defects of shielding glass by using a machine vision technology, and solves the problem that the defects inside and outside the shieldingglass are difficult to detect. The method comprises that a uniform background light illumination mode is used for detecting discoloration, large-size defects and the like; a parallel light illumination mode is used for detecting small-size defects; a glass defect detection method is used to control a plurality of light sources to perform single-side or front-back-side detection on shielding glass;a glass defect acceptance method is used select defects on a software interface according to a detected defect result, indicate defect positions on glass by utilizing an electric holder laser, and carry out manual judgment. The glass is comprehensively detected through the method, and the safety of using the shielding glass is improved.

Description

technical field [0001] The invention relates to a shielding glass defect detection method and system thereof, in particular to an automatic detection method for shielding glass products and glass original sheet defects by using machine vision technology for image acquisition. Background technique [0002] Electromagnetic radiation is produced by the movement of electromagnetic energy in space due to the movement of charges, and is a phenomenon in which electromagnetic waves are emitted or leaked into the air. With the development of electrical and electronic technology in today's world and the application of electronic products such as mobile phones and computers, the electromagnetic environment in human life is becoming more and more complex and diverse, and people are more and more seriously affected by electromagnetic radiation. Electromagnetic wave radiation has been listed by the World Health Organization as the fourth largest source of environmental pollution. It not o...
