Computer-Aided Design of a Mechanism for the Continuous, Automated Assembly of Two Parts at High Speed: A Case Study

Various computer-aided design tools were used to develop alternate designs for mechanisms to assemble two subassemblies of a consumer product on a fully-automated, continuous motion, high speed assembly line. The product geometry required a snap fit and the assembly motion had to be such as to avoid product damage. Four different mechanisms out of a larger number of concepts were developed in some detail and the most promising of those designed for production. All designs involved some combination of linkages and/or cams. This paper describes their design and the use of various CAD/CAE tools in the process.
