FIG. 11 is a schematic structural diagram of an assembly line for products to be boxed 200 , and FIG. 12 is a schematic structural diagram of an assembly line for folding and forming packaging boxes 30 . As shown in FIGS. 11 and 12 , in this embodiment, the assembly line of the products to be boxed 200 is regarded as the first assembly line 400 , and the assembly line of the folded and formed packaging box 30 is regarded as the second assembly line 300 . It can be seen from FIG. 1 that the second assembly line 300 and the gantry truss mechanism 10 are arranged side by side. The first assembly line 400 is perpendicular to the second assembly line 300 and is located between the gantry truss mechanism 10 and the second assembly line 300 . The boxing mechanism 40 is located on one side of the first assembly line 400 .

Specifically, the second assembly line 300 is used to transport refrigerators. The second assembly line 300 is provided with a scanning device 310 for identifying the model of the refrigerator and selecting a corresponding packaging box according to the model of the refrigerator. When the refrigerator moves to the first limit plate 330 on the second assembly line 300, the induction sensor will send a signal to the clamping cylinder 320. The clamping cylinder 320 will hold the refrigerator against the first limit plate 330, and the refrigerator will be at the first limit plate 330. This position stops and no longer moves forward.

The first assembly line 400 is used to transport the folded and formed packaging boxes 30 . When the folding and forming packaging box 30 enters the second assembly line 300, the cylinder sensor senses the signal, and the positioning cylinder 410 extends to fix the folding and forming packaging box 30 on the limiting column 440 to prevent the folding and forming packaging box 30 from collapsing. Then, the folding and forming packaging box 30 is transported on the first assembly line 400. Under the limit of the second limiting plate 420 and the limiting column 440 of the folding and forming packaging box 30, it is ensured that the folding and forming packaging box 30 is transported in an unfolded manner and reaches the limit position. The sensor stops moving after 430.

The working principle of this embodiment is as follows: According to the on-site refrigerator model production situation, the corresponding unformed plate-shaped packaging box 20 is prepared and placed on the base mechanism 50, and the unformed plate-shaped packaging box 20 is positioned by the positioning rod 51, so that the unformed plate-shaped packaging box 20 is positioned. The plate-shaped packaging boxes 20 are stacked together neatly and orderly. When the refrigerator is transported on the second assembly line 300, it will pass through the scanning device 310. The scanning device 310 will scan the specific QR code on the refrigerator to identify the model of the refrigerator and send it to the control system. The refrigerator will continue to be transported on the second assembly line 300. When the limit sensor is reached, the movement stops. At this time, the clamping cylinder 320 holds the refrigerator against the first limit plate 330 , and the refrigerator stops at the designated position on the second assembly line 300 . After receiving the signal from the scanning device 310, the control system will issue an instruction to the gantry truss mechanism 10. When starting for the first time, the second motor 131 moves, driving the second gear 132 on the output shaft of the second motor 131 to rotate, thereby driving the second bracket 133 to move, and the cross beam 111 also moves accordingly. It can be driven by the forward and reverse rotation of the second motor 131. The cross beam 111 moves forward and backward, and then stops moving after being adjusted to a suitable position. After receiving the command, the gantry truss mechanism 10 will send a signal to the first motor 141. Since the structure of the first gear 142 is fixed, the first motor 141 will rotate to drive the first adsorption structure 12 to move left and right. When the designated unformed shape is reached, The movement stops when the flat packaging box 20 is above the position, and the lifting cylinder 123 starts to move to drive the first support frame 122 to move. When it reaches the top of the unformed flat packaging box 20, the suction cup will automatically suck the unformed flat packaging box 20, and then the lifting cylinder 123 hangs the unformed plate-shaped packaging box 20, and the first motor 141 continues to operate to drive the first adsorption structure 12 to stop moving when it reaches above the first assembly line 400. At this time, the unformed plate-shaped packaging box 20 is still sucked by four rows of suction cups and is in a folded state. The control system continues to issue instructions, and the two rows of suction cups on the right are deflated. The unformed plate-shaped packaging box 20 unfolds from the crease. Half of it is sucked by the two rows of suction cups on the left, and the other half naturally falls at the crease by its own gravity. Packaging The whole box is in an unfolded state. When the folding and forming packaging box 30 enters the first assembly line 400, the cylinder sensor senses the signal, and the positioning cylinder 410 extends to fix the folding and forming packaging box 30 on the limiting column 440 to prevent the packaging box from collapsing. Then, the foldable packaging box 30 is transported on the first assembly line 400. Under the limit of the second limiting plate 420 and the limiting column 440, it is ensured that the folding and formed packaging box 30 is transported in an unfolded manner, and stops moving after reaching the limit sensor 430. . At this time, the robot arm 41 starts to move. The robot arm of the robot arm 41 rotates and lifts to drive the second adsorption structure to around the folding forming packaging box 30. The chute on the second adsorption component can move left and right to adjust the first suction cup group 422 and the second suction cup. The distance between the groups 423 is such that the foldable packaging box 30 is clamped, and then the foldable packaging box 30 is placed above the refrigerator through the rotation and lifting of each movement mechanism of the robotic arm. The suction cup of the second adsorption structure is deflated, thereby the foldable packaging box 30 is 30 is set on the outside of the refrigerator under the action of gravity.
