An automatic robot programming system was developed for PCB components insertion tasks.
The system uses as input CAD files which describes the relative positions of the components on the board information about the robotics cell, and some directions about jigs and fixtures used to locate the board on the workspace, as well as correct information about component feeders. The robot program generation using this system cuts off the hard task which involves getting the data from board design and exhaustive calculations relating to the robotic workspace and jigs and fixtures. The system needs files in AutoCAD standard, and several applications were made to validate it using an IBM 7535 SCARA robot. The whole system was developed in Pascal language and the resulting programs are written in AML. It was observed that it could reduce a lot of unproductive time if manually done. It was also an algorithm to check and avoid mechanical interference in the robotic insertion tasks.
