The mounting base 49 is set on the robot body. There are two fixed splints 50 and two movable splints 51 respectively. The two fixed splints 50 and the two movable splints 51 are distributed in a rectangular shape, and the two fixed splints 50 are respectively fixed on two adjacent side walls of the mounting base 49, and the two movable splints 51 are located next to the other two adjacent side walls of the mounting base 49, and each movable splint 51 is respectively connected to the material grabbing cylinder 52.

[0049] When the pushing finger 42 pushes the glued cardboard along the guide plate 41 to between the upper die 65 and the lower die 66, the stamping cylinder 64 drives the connecting column 67 to drive the upper die 65 to move downward, and makes the stamping surface of the upper die 65 contact the cardboard. When the stamping surface of the upper die 65 contacts the cardboard, the upper die 65 sucks the cardboard through the vacuum adsorption plate to prevent the cardboard from displacement. Then the stamping cylinder 64 continues to drive the upper die 65 to drive the cardboard to move downward, and makes the cardboard contact with the lower die 66. Through the cooperation of the upper die 65 and the lower die 66, the cardboard is folded into a packaging box 72 with an open top. The stamping cylinder 64 continues to press down, driving the upper die 65 to fold the packaging box. 72 falls onto the box-packing conveyor belt 11 through the forming through-hole 69. At the same time, the conveyor belt 53 drives the box body limit seat 13 to move between the two clamping plates 56 and is located directly below the lower die 66. The upper die 65 presses the packaging box 72 out of the forming through-hole 69. Then, the clamping cylinders 55 on both sides of the frame 54 drive the clamping plates 56 to move closer to each other, and the packaging box 72 is clamped between the two clamping plates 56. The stamping electric cylinder 64 drives the upper die 65 to retract, and then the clamping cylinder 55 drives the clamping plates 56 to move away from each other, releasing the packaging box 72, so that the packaging box 72 is placed on the box body limit seat 13. Then the conveyor belt 53 continues to drive the box body limit seat 13 moves forward, and when the packaging box 72 is transported to the guide box frame 58, the conveyor belt 53 stops moving, and the driving cylinder 57 drives the guide box frame 58 to descend, so that the guide piece 71 on the guide box frame 58 is inserted into the inner edge of the packaging box 72. Then the robot body 48 controls the mounting seat 49 to drive the fixed splint 50 and the movable splint 51 to move to the grabbing platform 6, so that the two fixed splints 50 and the two movable splints 51 are located around the arranged square bottles 73, and the movable splint 51 is driven by the grabbing cylinder 52 to move in the direction close to the arranged square bottles 73, and the arranged square bottles are pulled together by the two fixed splints 50 and the two movable splints 51. The square bottles 73 are clamped, and then the arranged square bottles 73 are grabbed from the grabbing platform 6 and put into the packaging box 72. Finally, the cylinder 57 is driven to drive the guide box frame 58 to rise, and the guide piece 71 on the guide box frame 58 is pulled out from the packaging box 72, and the height of the guide piece 71 exceeds the packaging box 72. The conveyor belt 53 continues to work and continues to convey the packaging box 72 containing the square bottles 73 forward. When the packaging box 72 containing the square bottles 73 is conveyed to the output end of the box conveyor belt 11, the box discharge cylinder 60 drives the box discharge plate 63 to extend to the box conveyor belt 11, and pushes the packaging box 72 containing the square bottles 73 out from the box body limit seat 13.
