[0041] The working principle of the present invention is as follows: in the present invention, the motor 6 drives the roller 16 to rotate through the belt 12 and then drives the robot to move left and right. At the same time, the motor 6 drives the worm 9 to rotate through the gear transmission. The worm 9 drives the lifting shaft 25 to lift in the sleeve 24, and the hydraulic cylinder 27 drives the clamping mechanism 3 to move left and right. The shock absorbing mechanism 1 is used to achieve shock absorption during the movement and braking process of the robot. The robot first moves from the manual operation position to the side of the injection molding machine, and at the same time, the lifting shaft 25 rises to the highest point; then the telescopic end of the hydraulic cylinder 27 is extended to the longest, and the clamping mechanism 3 clamps the workpiece on the injection molding machine. After clamping the workpiece, the telescopic end of the hydraulic cylinder 27 shrinks to the shortest; then the robot moves from the side of the injection molding machine to the manual operation position, and at the same time, the lifting shaft 25 drops to the lowest point; then the clamping mechanism 3 releases the workpiece, and the operator removes the workpiece from the clamping mechanism 3. The above is a working cycle of the robot. Because the screw 9 and the roller 16 are driven by the motor 6 at the same time, the rise of the lifting shaft 25 and the movement of the robot from the manual operation position to the injection molding machine are carried out simultaneously. Similarly, the descent of the lifting shaft 25 and the movement of the robot from the injection molding machine to the manual operation position are carried out simultaneously.
