Abstract
A robot for a production machine includes a parallel link mechanism including opposed first and second shorter-side links and opposed first and second longer-side links which form a parallelogram. A chuck is supported on the first shorter-side link. A guide rail is fixed to a base arm in order to movably support the second shorter-side link. The base end of a drive link is rotatably attached to the base arm, and the distal end of the drive link is attached to an intermediate portion of one of the first and second longer-side links. A drive mechanism is provided in order to rotate the base end of the drive link. This structure simplifies the mechanical system and the control system, reduces a space required in the vertical direction, and increases operation speed such as product removal speed.
