Robot claw with bag stacking and positioning functions

The invention discloses a robot claw with bag stacking and positioning functions. The robot claw is structurally characterized in that a main plate is connected with a support; the support is connected with a finger driving air cylinder, a baffle driving air cylinder, mounted bearings and swinging arm shafts; finger swinging arm mechanisms are connected with the swinging arm shafts and the finger driving air cylinder; the baffle swinging arm mechanisms are connected with the swinging arm shafts and the baffle driving air cylinder; fingers are mounted on the finger swinging arm mechanisms; and baffles are mounted on the baffle swinging arm mechanisms. During bag stacking, material bags are positioned by the the independently-driven bilateral baffles, and the baffles are opened after the fingers are opened, thereby avoiding material bag shifting, and realizing precise stacking of the material bags.
