Taking the hot water kettle body production line as the research object, a multirobot production line simulation scheme for hot water kettle body was proposed by using the RobotStudio and SolidWorks software. The layout and technology of the production line were introduced, and the designs of suction hand, pneumatic drive system, dynamic smart components of hand and the calibration of hand coordinate system were completed; the trajectory planning of the robot code disk workstation was carried out, and the program example of the workstation was given. Finally, the production simulation and the trajectory tracking simulation of the code disk workstation were carried out. The simulation results show that the trajectory planning and the reliability of continuous production of the production line are achieved. Using the scheme,each production unit can be reasonably planed and configured, the development cycle can be shortened, the investment risk of equipment can be reduced. It provides basis and verification platform for the design of physical production line. 
