Abstract:
A system for measuring a thickness of a workpiece having first and second sides, the second side defining a reference plane, the first side having a first angular orientation with respect to the reference plane, the reference plane further defining a target axis, the target axis extending perpendicular from a second side target point of the second side disposed in the reference plane through a first side target point of the first side, the system comprising:a) a first laser triangulation emitter/sensor sized and configured to emit a first laser beam at the first side target point, the first laser triangulation emitter/sensor being receivable of a first array of diffused laser beams reflecting from the first side target point; b) a first adjuster base engaged to the first laser triangulation emitter/sensor, the first adjuster base being operative to adjust the first laser triangulation emitter/sensor to emit the first laser beam in generally perpendicular relation to the first angular orientation of the first side; c) a first support column being pivotally engaged to the first adjuster base, the first adjuster base being pivotally movable with respect to the reference plane for facilitating adjustment of the first laser triangulation emitter/sensor; d) a first support base being removably engaged to the first support column, the first support column being vertically movable with respect to the reference plane for accommodating different thicknesses of the workpiece; e) a second laser triangulation emitter/sensor sized and configured to emit a second laser beam at the second side target point, the second laser triangulation emitter/sensor being receivable of a second array of diffused laser beams reflecting from the second side target point; and f) wherein the first and second array of diffused laser beams are respectively convertable into first and second signals for calculating the thickness of the workpiece along the target axis.
