FEA of Articulated Robot Arm for Electrical Terminals Screw Assembly Process

Abstract

Automation is driving a significant transformation in the industrial sector by enhancing productivity, improving skills, ensuring quality, and reducing both manpower requirements and production time. Our project mainly deals with the electrical terminal screw assembly operation, where the screwing is done manually with a screwdriver. Screw ranges from M4 to M8 with variations in screw head. Our challenge is designing a robot articulated arm for performing screwing operations using an electrical screwdriver. We conducted an in-depth review of research papers and articles to explore advanced technologies employed in similar operations across various industries. Based on this analysis, we carefully selected and optimized arm mechanisms to ensure efficiency and effectiveness. Worker process operation output and hand movements considered for designing articulated arms. How workers face fatigue due to manual operation considered and studied during designing articulated arms. This arm has an improved scope in motorized control. End effector we used is a torque adjustment electrical screwdriver. End effector position always needs vertically with variations in height and area of working. Here we used Solid Works for designing and model analysis.
