摘要： A method of securing a fastener to a workpiece includes a fastener that is loaded into a feeder, and an insertion head assembly that is provided adjacent to the feeder. The insertion head assembly includes an insertion actuator that has a movable insertion piston, and a clamp finger that is mounted to the insertion piston. The fastener is arranged beneath a movable fastener joining element that is carried by the insertion head assembly, the workpiece is positioned relative to a locating pin, the insertion head assembly is moved to engage the workpiece with the clamp finger, the fastener is brought into engagement with a locating pin, the fastener joining element is advanced relative to the clamp finger, and the fastener that is secured to the workpiece.

摘要： An assembly system, such as welding system, includes an assembly station that is configured to assemble a component to a part in a loaded position. A drag conveyor includes a movable conveyor member that supports multiple locating elements configured to cooperate with a locating feature on a part. A friction bar is arranged along the locating elements, and the locating elements extend beyond the friction bar. The friction bar is configured to support the part and reorient the part from an unoriented position to an oriented position while the movable conveyor member drags the part along the friction bar. A robot is configured to transfer a part from the oriented position on the conveyor to the loaded position at the assembly station, such as a welding unit.

摘要： A securing system, such as a welding system, includes a robot configured to transfer a part to a home position. A securing station has a frame and a gun supported on the frame. The gun includes first and second members movable relative to one another, which are first and second weld gun electrodes, for example. The gun is configured to secure a component to the part in a securing position during a securing operation. A float assembly interconnects the gun to the frame and is configured to permit the gun to glide relative to the welding frame between the home position and the securing position. A homing assembly includes a homing guide configured to release the welding gun from the home position during the securing operation, such as resistance welding fasteners to sheet metal workpieces.

摘要： An upper electrode assembly for welding fasteners includes a body that supports an electrode that has an aperture. The aperture is configured to receive a movable pin of a lower electrode assembly arranged opposite the upper electrode assembly. The lower electrode assembly supports a fastener in a welding position. The upper electrode assembly includes a position sensor which includes a position sensor member that is arranged in the body and is configured to cooperate with the pin to detect a fastener welding characteristic.

摘要： A conveyor for ferrous workpieces includes a frame. A static bed is affixed to the frame. The static bed has a workpiece support portion constructed from a non-magnetic material. The workpiece support portion defines a workpiece flow path. A drive assembly is arranged beneath the workpiece support portion. The drive includes multiple discrete magnets configured to move in a direction of the workpiece flow path. At least one guide rail extends upward with respect to the workpiece support portion on a side opposite the drive assembly. The guide rail is configured to orient a workpiece to a desired position with respect to the workpiece flow path.
