End effectors and feeders for swaging operations

An end effector for swaging operations, the end effector comprising:

• a swage gun;
• and
• a feeder, comprising:
• a collar magazine, configured to selectively eject a lock collar, the lock collar having a collar axis;
• a guide-block assembly, comprising:
• a guide block that comprises a slot, configured to receive the lock collar from the collar magazine at a first guide-block position along the slot;
• and
• an actuator, operable to move the lock collar along the slot from the first guide-block position to a second guide-block position, spaced away from the first guide-block position;
• a feed tunnel, coupled with the guide-block assembly;
• a dispensing bulkhead, coupled with the feed tunnel;
• and
• a gripping assembly, coupled with the dispensing bulkhead, rotatable relative to the swage gun, and comprising a first gripper arm and a second gripper arm,
• wherein:
• the dispensing bulkhead comprises a retention assembly, configured to releasably retain the lock collar in the dispensing bulkhead;
• the lock collar is movable along the retention assembly in a first direction;
• and
• the retention assembly comprises:
• a pair of first retention arms, spaced apart from each other and configured to prevent movement of the lock collar in a second direction, which is perpendicular to the first direction;
• and
• a pair of second retention arms, spaced apart from each other and configured to prevent movement of the lock collar in a third direction, which is perpendicular to the first direction and to the second direction.
