The invention discloses robot stacking equipment with a positioning function. The robot stacking equipment comprises a robot stacking equipment main body. A rectangular mounting groove is formed in one side of the robot stacking equipment main body, and arc-shaped positioning grooves formed in one side of the robot stacking equipment main body are formed in the four corners of the rectangular mounting groove correspondingly; rectangular through holes are formed in the inner walls of the sides, close to the rectangular mounting groove, of the arc-shaped positioning grooves, wherein openings areformed in one sides of the rectangular through holes; sector-shaped plates are welded to the four corners inside the rectangular mounting groove correspondingly, and mounting through holes are formedin the sides, away from the interior of the robot stacking equipment main body, of the sector-shaped plates; and the periphery of each mounting through hole is provided with four rectangular cavitiesformed in the corresponding sector-shaped plate. Economy and practicability are achieved, and maintenance personnel can dismantle a positioning device from the robot stacking equipment main body onlyby pulling the positioning device inside the rectangular mounting groove in the direction away from the interior of the robot stacking equipment main body and accordingly can maintain the positioningdevice conveniently.
