Abstract
A workpiece conveying apparatus includes: two SCARA robots each including a first arm supported on a raising and lowering frame through intermediation of a first joint, a second arm supported through intermediation of a second joint, a first arm driving mechanism configured to drive the first arm to rotate, and a second arm driving mechanism configured to drive the second arm to rotate; a raising and lowering mechanism for the two SCARA robots; a cross arm configured to couple distal ends of the second arms; a workpiece holding unit configured to releasably hold the workpiece; shifting devices provided to the cross arm and configured to shift a drive-side shifting member; and sliding devices provided to the workpiece holding unit and configured to shift the tool holder by an operation of causing the driven-side shifting member to be driven by the drive-side shifting member.
