ABSTRACT:
A dual axis translation mechanism for holding and moving an object of variable dimension to a position defined by first and second axis. The mechanism includes a frame, a carriage mounted on the frame for movement with respect to the frame in the first axis, and an object holding means coupled with the carriage for holding and moving the object with respect to the carriage in the second axis. A motor selectively drives a first shaft and a drive/brake assembly provides a second shaft which, in a drive mode of the assembly is driven synchronously with the first shaft and, which in a brake mode of the assembly is held non-driven while the first shaft is being driven. First and second endless belts are mounted for rotating movement within the frame and extend in a direction parallel to the first axis. The first and second belts are coupled to the first and second shafts, respectively, for receiving selective rotational movement therefrom, with the first belt also being coupled to the object holding means for causing selective movement of the object in a direction parallel to the second axis and the second belt being coupled with the carriage for causing selective movement of the carriage in a direction parallel to the first axis. The object holding means comprises as lead-screw having an end coupled to receive rotational movement in response to rotation of the first belt, and carries first and second nuts thereon, which are coupled to the first and second clamp arms, respectively.
