Part transfer system that uses existing part features, and a method of using the part transfer system

摘要

A part transfer system includes a robotic arm, and an end effector attached to the robotic arm. The end effector includes a locating pin that is operable to engage an existing part feature of a part. The presence of the existing part feature is required for the intended use of the part, and therefore serves a function of the part other than a transfer function. The existing part feature defines a circular aperture disposed on a feature plane. The locating pin includes an engagement portion that extends along a longitudinal axis of the at least one locating pin. The engagement portion includes a diameter that is tapered along the longitudinal axis such that the engagement portion of the locating pin engages a radial inner edge of the circular aperture on the feature plane along an approximately annular contact ring disposed about a circumference of the tapered portion.

主权项

1. A part transfer system comprising:
an end effector attachable to a robotic arm; wherein the end effector includes at least one locating pin operable to engage an existing part feature of a part, wherein the presence of the existing part feature is required for an intended use of the part; wherein the existing part feature defines a circular aperture disposed on a feature plane; wherein the at least one locating pin includes an engagement portion that extends along a longitudinal axis of the at least one locating pin; wherein the engagement portion includes a diameter that is tapered along the longitudinal axis such that the engagement portion of the locating pin engages a radial inner edge of the circular aperture on the feature plane along an approximately annular contact ring disposed about a circumference of the tapered portion, and the at least one locating pin includes a first locating pin, a second locating pin, and a third locating pin, with the first locating pin and the second locating pin disposed opposite the third locating in to grasp the part therebetween.
