Opening rotary table material frame capable of grabbing and placing workpieces between dense layers through mechanical arm

The invention discloses an open rotary table material frame capable of grabbing and placing workpieces between layers through a mechanical arm, and belongs to the field of mechanical engineering. The transferring material frame comprises a base, a material supporting disc capable of rotating horizontally is arranged above the base, a plurality of opening material supporting discs capable of rotating horizontally are arranged above the material supporting disc at intervals, the material supporting disc and the opening material supporting discs rotate along the center shafts of the material supporting disc and the opening material supporting discs, and mechanical arm taking and placing openings are formed in the opening material supporting discs. The manipulator taking and placing opening is used for allowing a manipulator to penetrate through the open material supporting disc to grab materials on the lower layer. Through the arrangement of the opening material supporting plates, when the mechanical arm grabs t
