Sorting and visual detection grader

Abstract

The invention discloses a sorting and visual detection grader. The sorting and visual detection grader comprises a sorting single fruit feeding mechanism, a visual detection mechanism and a grading actuating mechanism, wherein the sorting single fruit feeding mechanism is used for conveying single fruit, the visual detection mechanism is used for detecting the fruit level, and the grading actuating mechanism is used for sorting fruits according to the level. By using the sorting single fruit feeding mechanism, complex disordered target groups can be effectively and orderly arranged and are individually conveyed one by one, so that the grader is automatically operated; to-be-detected fruits can be detected and identified by the visual detection mechanism, the grading standard includes the maturity, defects, size and weight of the fruits, grading factors are diversified, the height is automated, the collision and extrusion between the fruits as well as between the fruits and the machine are effectively reduced, and the extrusion and collision damages to the fruits are greatly reduced; the fruits can be respectively sorted to corresponding collecting boxes according to the level by the grading actuating mechanism according to detection results of the visual detection mechanism, so that the automatic grading of the fruits is realized.

Description

technical field [0001] The invention relates to the technical field of fruit processing machinery, in particular to a sorting visual inspection and grading machine. Background technique [0002] In recent years, with the rapid development of image processing technology and computer technology, the use of machine vision technology to detect and identify target objects, coupled with transmission machinery to grasp and classify the target objects, whether in industry or agriculture, is Increasingly in-depth research and multi-directional application promotion. Among them, the automatic grading of fruits is gradually changing from the traditional purely physical and mechanical grading method to the non-destructive or low-loss grading method mainly based on machine vision detection and recognition. Many researchers in the field have carried out related research on the classification methods of visual recognition and mechanical mechanism execution classification, and some have ma...
