Vision-based spherical fruit automatic grader

Abstract

The invention discloses a vision-based spherical fruit automatic grader. The vision-based spherical fruit automatic grader comprises a frame, a detection device, a single fruit arrangement and conveying device, a grading execution device and a controller, wherein the detection device, the single fruit arrangement and conveying device and the grading execution device are distributed from top to bottom; the detection device is used for detecting surface information of fruits; the single fruit arrangement and conveying device is used for arranging single fruits and conveying the fruits to a fruitoutlet one by one; the grading execution device is provided with a plurality of fruit discharging holes with different sizes; and the controller is used for controlling the grading execution device to convey fruits falling from the fruit outlet to corresponding fruit discharging holes according to data detected by the detection device, and to push the fruits out of the fruit discharging holes. Furthermore, fruits of different maturities, sizes, textures and surface defects are discharged through the corresponding fruit discharging holes so as to realize the function of automatically grading the fruits. The vision-based spherical fruit automatic grader has the beneficial effects of simple structure, small size, accurate grading, safety and reliability.

Description

technical field [0001] The invention belongs to the technical field of fruit sorting equipment, in particular to a vision-based spherical fruit automatic grading machine. Background technique [0002] Due to the different sizes and irregular shapes of fruits, the prices of fruits of different appearances and sizes will be different, resulting in the need for fruit growers to sort different levels and appearances of fruits. At present, the grading methods of fruits mainly adopt manual grading and mechanical grading. Among them, the manual grading and sorting method has high labor intensity, high labor cost, low work efficiency and poor accuracy, and cannot meet the needs of modernization, scale and industrialization. The grading index of the mechanical grading machine is relatively simple, and it is easy to cause mechanical damage to the fruit during grading. Most of the spherical-shaped fruit automatic grading machines based on vision use the form of conveyor belts for ass...

Problems solved by technology

Among them, the manual grading and sorting method is labor-intensive, high labor cost, low work efficiency, and poor accuracy, which cannot meet the needs of modernization, scale and industrialization

The grading index of the mechanical grading machine is relatively simple, and it is easy to cause mechanical damage to the fruit during grading

Most of the spherical-shaped fruit automatic grading machines based on vision use the form of conveyor belts for assembly-line grading, but this kind of grading machine is bulky, occupies a large area and is expensive, and cannot be suitable for ordinary farmers and small-scale agricultural producers. Grading requirements

In addition, this spherical fruit automatic grading machine is in rigid contact with the fruit during work, making the skin of the fruit prone to abrasion
