Quality Control and Material Handling System Using Cognex Vision

Abstract

Programmable logic controllers have been an integral part of factory automation and industrial process control for decades. These systems perform many functions, providing a variety of analog and digital input and output interfaces, signal processing, data conversion and various communication protocols. The sole purpose is to develop a material inspection and sorting system prototype and also demonstrate the Cognex camera methodology on the Human Machine Interface (HMI). This system can handle a series of metallic and non-metallic objects with the barcode encoded. Mitsubishi controller FX3U-16MR/ES manufactured is the brain of this system. To control the speed of the conveyor variable frequency drive (VFD) is programmed and used. E-Designer-7 software is used to design the screen. We scanned the barcode on the metallic tin via Cognex vision system. The material of the metallic tin is scanned by the inductive sensor and if the barcode is good and the material of the metallic tin is metal, the metallic tin is considered as good metallic tin and will pass on conveyor till the good part section and if the metallic tin is nonmetal or the barcode is bad, it continues on conveyor till bad part section. The whole operation can be controlled using the HMI. This application can be implemented in various manufacturing industries such as but not limited to packaging industries, automobile industry. The Cognex camera have variety of application in pharmaceutical, electronic industries, who wants to keep a track data and product on the conveyor. The HMI has been designed to read all important data and control and monitor the system.
