In order to solve the problem of a food factory moon cake packaging production line requiring a lot of manpower and low efficiency,this paper builds an automated packaging workstation based on SCARA robot,offline programming based on the packaging process,simulation analysis of robot workstation work beat,workspace and trajectory planning. The workstation model is built using SolidWorks and RobotStudio,and the layout is planned with the actual scenario. The dynamic Smart components of robot suction cups,conveyor belts and packaging boxes are designed,I/O signals are created and connected,and programming and simulation analysis are carried out.The results show that the robot motion trajectory is smooth,the speed and acceleration are continuous,and after the application of SCARA robot in food packa- ging production line,the efficiency of the production line is improved and the manual labor intensity is reduced,which provides a reference for the intelligent upgrade and transformation of the automated production line.
