The invention discloses a multifunctional loading and unloading integrated robot, relates to the field of loading and unloading integrated robots, and provides the following scheme for solving the problems that an existing loading and unloading integrated robot is inconvenient to adjust and use flexibly, single in function and low in loading and unloading efficiency: the multifunctional loading and unloading integrated robot comprises an omni-directional vehicle platform, a six-axis mechanical arm and a square frame. An equipment bin is fixedly connected to the inner wall of the square frame, a push rod motor and a limiting barrel are fixedly installed on the upper end face of the equipment bin in an array mode, a suction cup is fixedly installed on the lower end face of the equipment bin, a screw is rotationally connected into the square frame, the surface, in the equipment bin, of the screw is fixedly sleeved with a first gear, and the two ends of the screw are both sleeved with sliding blocks in a threaded mode. A clamping mechanism is arranged on the lower end face of the sliding block, and an adjusting mechanism is arranged in the limiting cylinder. The multifunctional loading and unloading integrated robot has the characteristics that the robot can be conveniently adjusted, objects with different sizes, shapes and weights can be conveniently fastened and clamped, and the functionality of the robot is greatly improved.
