During assembly of measuring instruments most different frame parts have to be preassembled and screwed together. Separation points of the casing have to be tipped with electrically conductive high freqency sealing. In the described application the planning started with the design for assembly. Each component was analyzed to minimize the number of process risks. Considering the product structure, all assembly steps were layed down. One of the most important requirements was to assemble more then 20 different cases without any setup time. The result of the planning operations was the layout and technical concepts for all necessary tools and devices. By supervision of all processes, which are relevant for quality it can be guaranteed that only good parts are assembled. One of the technically most interesting automation potentials was assembling high frequency sealing. The non rigid seals with various diameters provided on rolls have to be joined in differently running slots. Additionally adhesive spots have to be placed on the bottom of the slot. Because of complex assembly tasks it is necessary to use an industrial robot with six axes. All handling operations in th assembly cell are lead by the robot.
