Method And Apparatus For Image Acquisition Utilizing A Concave, Cylindrical Reflector
US Patent:
4409478, Oct 11, 1983
Filed:
Jan 18, 1983
Appl. No.:
6/458932
Inventors:
Charles J. Libby - West Roxbury MA
Assignee:
Automatix Incorporated - Billerica MA
International Classification:
H01J 314
US Classification:
250236
Abstract:
A method and apparatus for image acquisition utilizing a non-planar beam of electro-magnetic radiation, such as, a hollow conical beam of light, to illuminate at least a portion of an object. The conical beam of light is generated by impinging a light beam on the surface of a concave, cylindrical reflector. The illuminated portion of the object is imaged on an array of photosensitive elements to produce corresponding signals that are representative of the image on the array. These signals can be used to obtain identification information concerning the object and guidance information for a plural axis manipulator employed in conjunction with the object. In one application the image acquisition apparatus is used in a robot to provide control signals for guiding the robot tool along a path, such as, a welding seam.
Method And Apparatus For Image Acquisition Utilizing A Hollow Shaft Motor And A Concave, Cylindrical Reflector

Appl. No.:
6/458836
Inventors:
Charles J. Libby - West Roxbury MA

The conical beam of light is generated by impinging a light beam on the surface of a concave, cylindrical reflector. The light beam enters the concave cylindrical reflector through the hollow shaft of a motor. The illuminated portion of the object is imaged on an array of photosensitive elements to produce corresponding signals that are representative of the image on the array. These signals can be used to obtain identification information concerning the object and guidance information for a plural axis manipulator employed in conjunction with the object.

Barry Gaiman - Bedford MA
Assignee:
Automatix Incorporated - Billerica MA
International Classification:
B23K 912
US Classification:
21912434
Abstract:
An arc welding system with image acquisition utilizing a non-planar beam of electro-magnetic radiation, such as, a hollow conical beam of light, to illuminate at least a portion of the welding object is disclosed. The conical beam of light is generated by impinging a light beam on the surface of a concave, cylindrical reflector having a longitudinal axis that preferably is parallel to the longitudinal axis of the welding torch. The light beam enters the concave cylindrical reflector through the hollow shaft of a motor. Rotation of the motor angularly positions the reflected light beam on the welding object. The illuminated portion of the object is imaged on an array of photosensitive elements to produce corresponding signals that are representative of the image on the array. These signals are used to obtain identification information concerning the welding object and guidance information for a plural axis manipulator that guides the welding torch tool along a welding seam. The image acquisition apparatus is optically and physically shielded from the welding arc by a replaceable shield.
