Realization of the quality assurance for robotized assembly cell

The paper presents a realized automated quality assurance system for the final assembly of a magnetic valve. The realization project joined to an international research project sponsored by the European Union however the quality assurance was not in the frame of that project. The system includes: (1) the supervision of the assembly cell and operations; (2) the functional test of the assembled valve; and (3) the automatic documentation and part following system. For realizing the aforementioned three components the original concept was worked out, the necessary design and plan were completed, the hardware and sensors were produced or installed, and the software was programmed. In the realization we had to consider the previously realized assembly cell, some economical constraints and the restrictions of the quality standard. The realized system has a close connection with the actual assembly process but the concept and the solution of the components can be applied generally after some not significant modification
