Abstract:
An apparatus for delivering and installing fasteners to and through a workpiece comprising:an automated machine movable along a first surface of the workpiece; an end effector mounted on the automated machine and operable to drill a hole through the workpiece and insert a fastener through the hole, the end effector comprising an electromagnetic clamping device that generates a magnetic field; a positioning device located proximate the end effector and operable to generate a positioning signal that is detectable proximate a second surface of the workpiece on an opposite side from the first surface; a fastener feed unit operable with the automated machine to deliver the fasteners through the end effector and into the workpiece; a controller that positions and activates the automated machine, the end effector, and the fastener feed unit; a hand-held tool comprising a magnetic clamping block disposed against the second surface of the workpiece and aligned with the electromagnetic clamping device, wherein when the magnetic field is generated, the workpiece is clamped between the magnetic clamping block and the electromagnetic clamping device to enable the end effector to drill a hole through the workpiece and insert a fastener therethrough; and a detector located on the hand-held tool for detecting the positioning signal and for generating guidance information to inform an operator where to move the hand-held tool so as to align the magnetic clamping block with the electromagnetic clamping device.
