Abstract

This article details a linear placement compensation mechanism for an assembly machine intended for inserting a number of key buttons or similar small objects into a regular rectangular matrix. The matrix may be a molded plastic framework having a number of equidistantly spaced openings into which key buttons are to be placed. A problem with molded plastic frameworks is that upon cooling, a linear shrinkage takes place so that the center-to-center spacing of apertures in the rectangular matrix array vary as their distance from the center of the framework increases.
