The invention provides an intelligent palletizing robot for a container. The intelligent palletizing robot comprises a vehicle body and an end effector, two supporting telescopic bottom rods are fixedly installed at one side of the bottom of the vehicle body, and a placement plate is fixedly installed between the two supporting telescopic bottom rods; the supporting telescopic bottom rods compriseouter rods and inner rods, telescopic grooves are formed in one ends of the outer rods, third hydraulic rods are fixedly installed at the portions, away from the inner side walls of the opened ends,of the telescopic grooves, and one ends of the inner rods penetrate through the opened ends of the telescopic grooves and are fixedly connected with output shafts of the third hydraulic rods; a supporting arm is fixedly installed at the top of the placement plate, and a connecting base is installed at the top of the supporting arm through a rotary shaft. The intelligent palletizing robot for the container is reasonable in design, and can work in the container, the end effector can grab an object with hands or a suction cup, so that the grabbed object is prevented from being damaged, and the practicability is high.
