Simulation Design of Spot Welding of Body Structure and Transfer Robot Workstation

Abstract

Application of virtual simulation technology to manufacturing industry today can shorten the development cycle, reduce costs and improve the design accuracy. This paper takes the spot welding workstation of auto body structure as the research object. Firstly, the production demand of spot welding of auto body structure is analyzed, the structure and production characteristics of spot welding robot workstation are analyzed, and the appropriate equipment is selected for the layout of spot welding robot workstation. Secondly, the work path of the robot is planned reasonably, and the planning of the robot trajectory can facilitate the writing of program instructions later. In the design process, three-dimensional modelling software is used to model some components in the workstation. Finally, through the use of simulation software, the welding path optimization and off-line programming of the whole spot welding robot workstation are simulated. The results show that the designed robot workstation can meet the use requirements.
