Patent ID: 11554466

Abstract:
An end effector for installing pre-molded seal caps onto fasteners comprises a cap-dispenser assembly and a cap-placement assembly. The cap-placement assembly comprises a main housing and a plunger mechanism, comprising an outer plunger housing and an inner gripper. The inner gripper is rotatable relative to the outer plunger housing between a cap-retaining configuration and a cap-releasing configuration. The plunger mechanism is selectively translatable from an extended position to a retracted position and from the retracted position to the extended position. The main housing is selectively rotatable from a cap-receiving position, in which the plunger mechanism is aligned with the seal-cap-delivery-sleeve central axis, to a cap-installing position, in which the main housing is angularly displaced from the cap-receiving position, and from the cap-installing position to the cap-receiving position.
