Didactic prototype of a robotic manufacturing cell to program welding trajectories in a frame

Abstract

This project shows the integration of a didactic prototype of a robotic manufacturing cell for the programming of welding trajectories in a chassis. The purpose of this project is to integrate the robotic cell through the interaction of the controller of an industrial robot, a programmable logic controller (PLC) and a power transmission system for the positioning of a chassis for didactic purposes for students studying engineering in the area of Industrial Automation. To carry out the project, a scale chassis for a tractor and its support base was first manufactured, then the control of a stepper motor was carried out through a SIMATIC S7-1200 CPU 1214C PLC and a microstep driver module. The programming software COSIMIR from FESTO was also used to program the welding trajectories in a Mitsubishi RV-2AJ robot with 5 degrees of freedom that interacts with the PLC through input and output digital modules. Finally, it was possible to obtain a functional prototype of a robotic manufacturing cell that can be used for teaching robot trajectory programming and that is closely related to industrial machines.
