Abstract
An 'on-the-fly' component registration system comprises a two-dimensional imaging camera carried by a component placement nozzle platform in turn carried by a positioning gantry. A reflective surface located on or adjacent to a workpiece on which a component is to be placed allows the camera to image by reflection therefrom the component held by the component placement nozzle and an associated machine vision system to determine position correction information (e.g., .DELTA.x, .DELTA.y and .DELTA..theta.) therefrom while the component placement nozzle platform is traveling on the positioning gantry from a component supply station, by the reflective surface, on the way to a component placement target position on the workpiece.
