Visual sorting method and visual sorting system suitable for hard workpieces

Abstract

A visual sorting system suitable for hard workpieces and a visual sorting method for sorting hard workpieces using the sorting system. The visual sorting system includes a camera, a processor, and a transfer tray; the transfer tray includes a tray, and blades for supporting hard workpieces are arranged on the outer edge of the tray, and the grid structure is formed by the blades; the blades are wear-resistant Hard blades. The blades are made of 40Cr steel. Compared with the traditional glass turntable, the price of 40Cr steel is moderate and easy to process. After heat treatment, the material itself can obtain certain toughness, plasticity and wear resistance, which can improve the cost of the blade. Lifespan of the invention. In addition, the blade adopts a symmetrical structure design form up and down, so that the blade can be used on both sides, which greatly prolongs the service life of the blade. In addition, the transfer tray designed by the present invention adopts a grid structure, which solves the problems of dust coverage and wear during the sorting process while ensuring light transmission.

Description

technical field [0001] The present invention relates to the technical field of visual sorting, and more specifically, to a visual sorting method suitable for hard workpieces and a visual sorting system suitable for hard workpieces. Background technique [0002] In recent years, machine vision technology has developed rapidly, and it has been maturely applied to smart devices in most fields. Among them, logistics, agriculture, and sorting of regular-shaped industrial products are the most widely used. [0003] For items with regular shapes, such as express packages, tobacco, gears, steel balls, etc., machine vision technology can be used for product sorting. As a diamond cutter head with fixed properties, the application of machine vision technology is almost blank. The main reason for this situation is that there is no suitable transfer disc to meet the requirements of diamond cutter head visual sorting, for example: diamond The cutter head has high hardness, and the produc...

Problems solved by technology

As a diamond cutter head with fixed properties, the application of machine vision technology is almost blank. The main reason for this situation is that there is no suitable transfer disc to meet the requirements of diamond cutter head visual sorting, for example: diamond The cutter head has high hardness, and the product surface carries a lot of dust. The glass transfer trays used in most visual sorting equipment are prone to scratches and become blurred, making it impossible to perform accurate measurements.

[0004] Through analysis, if the current ordinary glass transfer tray is used for sorting diamond cutter heads, the following problems will occur: 1. The transfer tray of conventional visual sorting equipment usually uses a glass tray for light transmission. Due to its high hardness, coupled with the large amount of fine particle dust generated during the sorting process, the glass surface is easily scratched and cannot be measured accurately; 2. Due to the large amount of dust, the glass transfer tray must be cleaned frequently, and the labor cost for equipment maintenance High; 3. When the visual sorting equipment is applied to the field of hard alloys such as diamond cutter heads, the life of the equipment will be greatly reduced due to the material of the transfer tray

[0005] To sum up, how to solve the problem in the prior art that cannot meet the visual sorting requirements of the diamond cutter head in the ordinary transfer disc has become an urgent problem to be solved by those skilled in the art
