Diseño y construcción de un prototipo de control automático que permita aceptar o rechazar tramos de bandejas porta cables por medio de visión artificial para la empresa Sedemi

Abstract

The present project consist in the design and construction of a machine to do quality control in laterals of cable trays for Sedemi Company. To get the proposed goal artificial vision is used and computer assistance to analyze the images. The laterals of cable trays are used to transport electrical power and control cables. Its shape and material depends of application in which it is used. Actually, the quality control process is manual, and is performed measuring the distance of the holes witch each other and the edge of the cable trays. However, this process is repetitive and tedious for the workers. In the artificial vision process are used two web cams located in the extreme of the cabins, while HMI is used to process the information using Matlab GUI. The program compares the percentage of similarity between each part of the photograph taken with a photograph that have previously been accepted by the quality control department, if that percentage is similar, the lateral of tray is approved, and otherwise it is rejected. The cabin can detect the width of the cable tray by using optical sensors. The mechanical design of the cabin components is done by finite elements.
