Embodiment Construction

[0019] Such as figure 1 , 2 A steel ball sorting device based on machine vision includes a feeding mechanism 10, a feeding channel 11, a feeding tray 2, a detection chamber 12, a detection light source 14, a camera 13, a tray 5, a tray support 6, an unfolding tray 9, Ball outlet mechanism 4 and ball outlet 3.

[0020] The feeding mechanism 10 is connected with the feeding plate 2 installed in the detection tank 1 through the feeding channel 11, and transports the steel balls to be inspected to the feeding plate 2 according to the set ball feeding frequency. The feed plate 2 is made of milky white light-transmitting material, and a number of detection cavities 12 are evenly distributed on its circumference. The detection cavity 12 is a circular through hole penetrating the upper and lower surfaces of the feed plate 2, and its machining accuracy should meet the requirements for measuring the outer diameter of the steel ball. The distance between the centers of the several det...

Abstract

The invention provides a steel ball sorting device and a method based on machine vision. Surface characteristics of steel balls are obtained on line; the sorting of the steel balls is realized according to a quality control target; the surface of each steel ball to be detected is sufficiently expanded by coordinated rotation movement of a feeding disc and an expanding disc, and the expanding disc does not need to swing, so that the operation of a detection device is more stable and more reliable, and the structure is simple; and therefore, the existence of swing movements in a detection process is avoided and a detection result is more accurate. Meanwhile, a method for measuring the outer diameters of the steel balls in introduced in and the steel balls which cannot meet size requirements are removed according to a measuring result, so that the sorting device can more perfectly meet actual requirements.

Description

technical field [0001] The invention belongs to the field of measurement technology and automatic control, and relates to a device for online detection of product surface defects and dimensional parameters in automated manufacturing, specifically, a device for online acquisition of steel ball surface features and dimensional parameters based on machine vision , and at the same time issue a control command according to the detection feedback information, and realize the steel ball sorting device according to the quality control target. Background technique [0002] In product quality testing, most of the surface defects of the measured objects are inspected manually. Due to the great influence of human factors, its accuracy and stability are difficult to guarantee, and for tiny objects (such as small steel balls) ) is basically difficult to detect with the naked eye; for the geometric parameters of the measured object (such as the diameter of the steel ball), the traditional ...
