ABSTRACT:
A powered fastener installation apparatus and method wherein the successful installation of a fastener is indicated by directly detecting the event of the fastener stem breaking. The device releases any partially upset fastener before withdrawing from the workpiece so as to prevent damage to the workpiece. The fastener installation device includes means for transferring the fastener from a feed module to the pulling head and avoiding partial upsetting or disassembly of the fastener, which can lead to jamming the device. The pulling head and transfer apparatus are provided with a vacuum to retain the fastener without mechanical gripping, thereby allowing easy purging of the fastener and preventing the fastener from falling out of the device unintentionally. Moreover, use of the vacuum retention allows greater flexibility and tolerance of errors in the placement and angular orientation of the robot arm and workpiece. The load and feed phases of the cycle overlap to reduce cycle time and can occur while the apparatus is being moved to a second fastener installation location.
