Full-automatic intelligent sheet selection machine for neodymium-iron-boron magnetic workpieces based on machine vision

Abstract

The invention discloses a full-automatic intelligent sheet selection machine for neodymium-iron-boron magnetic workpieces based on machine vision. The full-automatic intelligent sheet selection machine comprises a rack, wherein an upper computer, a PLC (Programmable Logic Controller), a communication conversion card and a main load-bearing steel plate are fixedly mounted on the rack; a loading transmission belt, a servo motor, a glass turntable, an approach switch, three solenoid valves, three pneumatic nozzles, three discharging cylinders, four image collection cameras, a coaxial light source and a backlight source are mounted on the main load-bearing steel plate; the servo motor is used for driving the glass turntable to rotate at a constant speed, thereby driving the workpieces to carry out uniform circular motion and sequentially pass through the approach switch, the pneumatic nozzles and the image collection cameras; the parts respectively carry out corresponding actions under the control of the PLC. The full-automatic intelligent sheet selection machine for neodymium-iron-boron magnetic workpieces is capable of effectively integrating hardware modules from the aspects of hardware structures based on the principle of machine vision, thus solving the problems of low detection accuracy, slow speed and high costs for detecting the neodymium-iron-boron magnetic workpieces.

Description

technical field [0001] The invention relates to the technical field of automatic detection equipment, in particular to a fully automatic intelligent piece selection machine for NdFeB magnetic workpieces based on machine vision. Background technique [0002] Machine vision is the use of machines instead of human eyes for measurement and judgment. The machine vision system refers to converting the ingested target into an image signal through a machine vision product (that is, an image capture device, which is divided into two types: CMOS and CCD), and sending it to a dedicated image processing system. The image system performs various calculations on these signals to extract the characteristics of the target, and then controls the on-site equipment actions according to the results of the discrimination. [0003] China is a big producer of NdFeB magnetic materials, but many manufacturers of magnetic materials either stay in the manual inspection stage or use relatively simple ...
