Abstract

The application discloses a sorting device and method for recognizing the size of litchi fruit pits based on machine vision. There is a machine vision device; a sorting mechanism is installed at the front end of the rack, and the sorting mechanism is equipped with a sorting upper channel and a sorting lower channel, and an adjustment mechanism is installed at the lower part of the sorting mechanism; The mechanism enters the conveying mechanism, and each litchi is sequentially conveyed to the sorting mechanism through the conveying mechanism, and the size of the litchi core is detected by the machine vision device, and the detection result is sent to the adjustment mechanism. After the corresponding litchi arrives at the sorting mechanism, the adjustment The mechanism adjusts the position of the lower sorting channel according to the detection results, so as to guide the lychees into the corresponding collection boxes through the upper sorting channel or the lower sorting channel. The application has the advantages of simple structure, convenient operation, low cost and no damage to the pulp, and is suitable for production lines.

Description

technical field [0001] This application relates to the field of mechanical automation, in particular to a sorting device and method for recognizing the size of litchi stones based on machine vision, which can be used for sorting the stones of all kinds of litchi, longan or other fruits. Background technique [0002] my country is a big litchi country. According to statistics in December 2018, the total area of ​​litchi planted in my country is 8.13 million mu, with an annual output of 2.296 million tons. However, lychee is a typical seasonal fruit with a concentrated ripening period and a short shelf life. During the lychee production period, oversupply tends to occur, resulting in some lychees being unsalable. Therefore, with the increase of lychee production, the sales products will inevitably become more and more diverse, and the sales channels will inevitably become wider and wider. Litchi will depend on deep processing, and processing equipment related to lychee will be...
