Automated high-frequency sealing in measuring instruments

During the 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 frequency 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 than 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. Nonrigid 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 the assembly cell are lead by the robot
