Process Parameters Study on Robot Rope Hemming of the Hood

Abstract

According Robot roller hemming is known as an assembly method with high flexibility and automated rate for closures in automotive bodies. The hemming tool is manipulated by controlling the industrial robot to complete the formation of closures (i.e. doors, hoods, tailgates and trunklids). In this paper, we shall first briefly introduce the rope hemming process, detail on the impact of process parameters on the rope height, roll-in and roll-out with the FEA model to simulate the rope hemming process. Then the rope hemming defects are discussed in later sections. This paper studies the process parameters and the methods to improve the rope hemming quality and provides a good reference for the practical application.
