Elektronikmontagevorrichtung mit Höhenerfassungssensor

摘要

A pick and place machine, and its imaging system are disclosed. The imaging system is movable with a head of the pick and place machine and includes a linear detector which is adapted to move proximate the component to thereby scan the component. The imaging system provides an indication of feature height on a component held by the pick and place machine. The height is based upon the intensity of a plurality of focused images. A method for sensing feature height of an object on a component as well as the coplanarity of objects held by a pick and place machine is also provided.
