Abstract: Taking double suspended film insulating glass production line as the research object, a simulation scheme of glass production line in double suspended film was constructed based on virtual simulation software platform. Firstly, the process of production line design based on virtual simulation technology is introduced. Secondly, the design of the film welding manipulator was completed and the robot was selected according to the parameters of the manipulator. Then the robot and the overall production line planning, using simulation software to set up the process of each action, to achieve the workspace and motion trajectory analysis, to prove its rationality; Finally, the production beat of the whole process is calculated, and the balance rate of the assembly line shows that the production line meets the expected goal. This scheme can reasonably plan and configure each production unit, shorten the development cycle, reduce the risk of equipment damage, and provide a basis and verification platform for the design of entity production line.
