In the past few years, a significant increase in industrial machine vision applications has appeared. Machine vision is also the main topic of this thesis, describing one of the terminals in the assembly process, which manufactures backlighting for the automotive industry. The described terminal places the last foil and the notch tape on the semi-finished product. The thesis describes the Cognex Designer program, which is used as a basis for the operation of the system, and all other necessary elements that enable its proper operation.
The thesis is divided in to three chapters. The first chapter describes the basic process of backlighting assembly. The second chapter presents the necessary hardware and describes all necessary elements, which comprise the machine vision system, and the calculations, which determine proper camera lenses. The third chapter presents the Cognex Designer software in more detail and describes the development process of the user interfaces and all other necessary tools. Furthermore, operation of the program for product inspection and determination of the foil and notch tape position is also described.
