Initial Mot ion Analysis for Pushing Point of Robotic Snap Assembly

摘要

A snap-fit is a mechanical joint system where part-to-part attachment is accomplished with location and locking features. This paper analyzes the relative motion between two parts during a snap assembly process, aiming at providing a better assembly method. To make the elastic deformation of snap joints during a product assembly as small as possible, we focus on three different pushing configuration. i.e.,1)pushing at the middle point, 2) pushing at corner points, and 3) pushing at the point just above snap joint. We evaluate the maximum elastic energy through physical simulation of snap assembly. Through physical simulation, we found that pushing at the point above the snap joint is the best method.
