Vision-based steel ball sorting device

Abstract

The invention provides a steel ball sorting apparatus based on visual sense, which comprises: an outer section bar framework, a steel ball distributing apparatus, an ejection apparatus, collection boxes and a control system, wherein, the steel ball distributing apparatus is fixed at the upper part of the outer section bar framework; an image acquisition apparatus of the control system is fixed at the upper portion of the outer section bar framework, and a lens is opposite to the lower part of the outlet of the steel ball distributing apparatus; the ejection apparatus is fixed at the bottom portion of the outer section bar framework, and an ejection plate surface of the ejection apparatus is opposite to the outlet of the distributing apparatus; the collection boxes are distributed uniformly and are fixed at the bottom of the outer section bar framework. The invention realizes the whole process of steel ball separation, steel ball dimension identification and steel ball collection with characteristics of high efficiency, good accuracy, simple structure and easy realization.

Description

technical field [0001] The invention relates to the technical field of mechatronics, in particular to a vision-based steel ball sorting device. Background technique [0002] The steel ball sorting mechanism is a common device in modern industry. Its purpose is to realize the classification of steel balls according to different steel ball classification standards. Generally, the steel ball size is used as the standard to screen out the qualified steel balls within the tolerance zone and reject the outside of the tolerance zone. Unqualified steel balls are widely used in the production and quality inspection of steel balls. [0003] After searching the existing technical documents, it is found that the Chinese patent application number is: CN200720109642.0, and the patent named "Steel Ball Screening Machine" includes a machine base, a driving device, two rotating shafts, a rotating shaft bearing seat, and a rotating shaft adjustment device. Distributing box and unloading devi...

AI Technical Summary

Problems solved by technology

First of all, the device relies on the accuracy of the mechanical structure to achieve sorting, which requires high machining accuracy for the long shaft and the matching accuracy between the bearing seat and the shaft, resulting in machining errors in the circumferential direction of the shaft, bearing clearance, and gaps between bearing positions. The error will significantly affect the sorting accuracy; secondly, the sorting accuracy adjustment of the device is manually adjusted by the support of the bearing seat, which affects the automation and operability of the sorting process; thirdly, due to the need for a long roller Realize sorting, take up a lot of space
