Claim of US Patent No. 10,039,219

1. A device, comprising:at least one controller;
a track defining a common X-axis;
a first robot, controlled by the at least one controller, comprising:
a first X-axis driven element configured for movement along the track defining the common X-axis;
a first Z-axis driven element, attached to the first X-axis driven element, configured for selective movement parallel to a Z-axis and along the common X-axis;
a first Y-axis driven element, attached to the first Z-axis driven element, configured for selective movement parallel to a Y-axis, the Z-axis and along the common X-axis; and
a first end-effector, attached to the first Y-axis driven element and configured for acting upon a device under manufacture; and
a second robot, controlled by the at least one controller, comprising:
a second X-axis driven element configured for movement along the track defining the common X-axis;
a second Z-axis driven element, attached to the second X-axis driven element, configured for selective movement parallel to the Z-axis and along the common X-axis;
a second Y-axis driven element, attached to the second Z-axis driven element, configured for selective movement parallel to the Y-axis, the Z-axis and along the common X-axis; and
a second end-effector, attached to the second Y-axis driven element and configured for acting upon a device under manufacture; and
wherein the device further comprises:
a workpiece supply tray configured to support a supply of workpieces to be integrated into the device or devices under manufacture; and
at least one workpiece supply tray motor configured to relocate the workpiece supply tray.
