Bearing detecting and sorting device based on machine vision

Abstract

The invention discloses a bearing detecting and sorting device based on machine vision. The bearing detecting and sorting device comprises a charging mechanism, a detecting mechanism and a sorting mechanism; a to-be-detected workpiece sequentially passes through the charging mechanism, the detecting mechanism and the sorting mechanism; the charging mechanism is used for conveying the to-be-detected workpiece to the detecting mechanism; the detecting mechanism detects the to-be-detected workpiece by adopting a machine vision mode; the sorting mechanism sorts the corresponding to-be-detected workpiece according to a detecting signal of the detecting mechanism. The detecting mechanism comprises a supporting disc, a feeding rotation disc, a servo motor, a first unfolding disc, a first servo motor, a first detecting camera, a turnover mechanism, a second unfolding disc, a second servo motor and a second detecting camera; the turnover mechanism comprises a push rod, a tray and a turnover channel. According to the invention, the machine vision mode is adopted for detecting surface defects of a bearing, so that the surface of the bearing is subjected to complete vision covering so as to guarantee the detection accuracy; a rotation disc type structure capable of detecting continuously is adopted, so that the detecting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of bearing surface defect detection and sorting equipment, and in particular relates to a machine vision-based bearing detection and sorting device. Background technique [0002] In the quality inspection of bearings, most of the defects on the bearing surface are inspected manually. This method is greatly affected by human factors, and it is difficult to ensure accuracy and stability. It is also difficult for the human eye to distinguish small defects. At present, there are existing domestic equipment for automatic detection of steel ball surface defects, such as a machine vision-based steel ball sorting device and method disclosed in Patent Publication No. CN102658266A. Features such as contact, real-time, flexibility and accuracy can effectively solve these problems. In addition, this method can not only obtain the surface characteristics and size parameters of the measured object, but also give feedback...

AI Technical Summary

Problems solved by technology

The software for image processing based on machine vision is relatively mature. However, no automatic detection equipment for detecting bearing surface defects has been developed yet. The main technical bottleneck is the mechanical structure design for complete visual coverage of the bearing surface. The bearing mainly has an outer ring. , an inner ring, a number of steel balls, steel ball cages and dust covers on both sides. The detection of bearing surface defects mainly includes the detection of surface defects on the outer wall of the outer ring, the inner wall of the inner ring and the dust covers on both sides. Since the bearing has two opposing surfaces, it is difficult to ensure complete visual coverage of the bearing surface and inspection efficiency at the same time
