Tray for apple positioning and rotating

Abstract

The invention discloses a tray for apple positioning and rotating, belongs to the technical field of agriculture, and relates to the field of fruit grading devices. The tray mainly comprises a shell,a friction column, a rotating platform, a friction ball shaft, a friction ball, a bearing bead and a flat plate. The friction column makes contact with a friction roller and the rotating platform at the same time; through the effect of friction force, when the tray moves, the rotating platform rotates; the lower side of the friction ball makes contact with the friction roller, and when a tray bodymoves, the friction ball rotates under the friction force. When a protruding part of an apple makes contact with the friction ball, the apple randomly rotates under the effect of friction; when the apple rotates and a concave part of a stem or calyx of the apple is located over the friction ball, the apple does not make contact with the friction ball, and the apple can not rotate. By means of thedesigned tray for apple positioning and rotating, the problems that when an image spectrum is obtained by an existing device through multiple cameras, cost is too high and a collected spectrum imageis not comprehensive enough are solved.

Description

technical field [0001] The invention relates to on-line monitoring and sorting of sugar acidity inside fruit, which belongs to the field of fruit online non-destructive testing and sorting technology, especially in the non-destructive testing assembly line of apples, which can be used to deal with the problems of position deviation and difficulty in multi-point image acquisition in apple image collection . Background technique [0002] In the global fresh consumption, fruit consumption occupies a pivotal position. With the steady increase of per capita income, people now pay more attention to not only the external quality of fruit, such as size, shape and color, but also the internal quality, such as apples. Brix and acidity etc. Quanguan has a variety of non-destructive testing and grading equipment for apples on the market. One of them is based on image collection technology. This equipment collects external images of apples and near-infrared spectra, and judges the quali...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of high manufacturing cost of existing apple non-destructive testing and grading equipment and insufficient comprehensive image collection, we specially designed and invented a tray that can realize apple positioning and rotation. The introduction of rotation technology makes it possible to use a single camera. It can achieve the effect of illuminating multiple surfaces of the apple to reduce the use of cameras, thereby greatly saving equipment manufacturing costs
