Specifically, the transverse movement mechanism 81 is a screw linear module. One end of the screw linear module is located directly above the material transfer work point, and the other end is located directly above the material transfer workbench 6. The motor drives the screw to rotate, thereby causing the slide arranged on the screw to move linearly. The vertical movement mechanism 82 is arranged on the transverse movement mechanism 81. The transverse movement mechanism 81 is used to drive the vertical movement mechanism 82 to move horizontally. The vertical movement mechanism 82 is a cylinder or a hydraulic cylinder. The suction plate 83 is arranged on the vertical movement mechanism 82, and the suction plate 83 is driven to move vertically by the vertical movement mechanism 82. The suction plate 83 includes a suction plate 83 body and a There are several suction ports 830, which are connected to the vacuum pump through an air pipe. The vacuum pump forms a vacuum environment at the suction port 830, so that the suction plate 83 can adsorb the bottom support of the wine box. When the bottom support of the wine box is transported, the horizontal movement mechanism 81 is used to drive the vertical movement mechanism 82 and the suction plate 83 to move as a whole to above the material transfer working point, and then the vertical movement mechanism 82 drives the suction plate 83 to move downward, and the suction port 830 contacts and adsorbs the bottom support of the wine box. Then the vertical mechanism drives the suction plate 83 to move upward, and the horizontal movement mechanism 81 drives the vertical movement mechanism 82, the suction plate 83 and the bottom support of the wine box to move horizontally to just above the material transfer workbench 6. Finally, the vertical movement mechanism 82 drives the suction plate 83 and the bottom support of the wine box to move downward, and the suction port 830 stops adsorption, so that the bottom support of the wine box is placed on the material transfer workbench 6.

[0045] In order to improve the working efficiency of the bottom support of the wine box, two suction discs 83 are configured. The two suction discs 83 are arranged and connected and fixed along the straight direction of the conveyor belt 2. The blocking member 7 is configured with two suction discs 83.

When distributing materials, the bottom supports of the wine boxes stacked in a pile are pushed to the distributing hole 10. At this time, the upper support plate 410 retracts and the lower support plate 420 extends. The bottom supports of the wine boxes fall from the distributing hole 10 to the lower support plate 420, and the lower support plate 420 bears the weight. Then the upper support plate cylinder 41 drives the upper support plate 410 to extend and insert into the gap between the bottom supports of the wine boxes. The lower support plate 420 retracts and bears the weight through the upper support plate 410. The bottom supports of the wine boxes located on the lower side of the upper support plate 410 are kept in a stacked state by the friction between the bottom supports of the wine boxes. Then the vertical cylinder 431 drives the horizontal cylinder 432 and the distributing plate 433 to move upward, so that the distributing plate 4 33 is aligned with the stacking seam of the bottom wine box bottom support, and then the dividing plate 433 is driven by the horizontal cylinder 432 to move horizontally and extend, and the dividing plate 433 is inserted into the stacking seam of the bottom wine box bottom support, and then the dividing plate 433 is driven downward by the vertical cylinder 431, driving the downward peeling of the bottom wine box bottom support, and the peeled wine box bottom support falls to the supporting rack 5, is supported by the supporting rack 5 and lowered to the conveyor belt 2, and finally the horizontal cylinder 432 drives the dividing plate 433 to retract and return to its original position, the lower supporting plate 420 extends, the upper supporting plate 410 retracts, the wine box bottom support drops the lower supporting plate 420, and the peeling of the bottom wine box bottom support is repeated.

[0047] The specific working process of this embodiment is as follows:

[0048] The stacked wine box bottom supports are pushed to the material distribution hole 10, at which time the upper support plate 410 retracts and the lower support plate 420 extends, and the wine box bottom supports fall from the material distribution hole 10 to the lower support plate 420, and the lower support plate 420 bears the weight, and then the upper support plate cylinder 41 drives the upper support plate 410 to extend and insert into the gap between the wine box bottom supports, and the lower support plate 420 retracts, and the wine box bottom supports are loaded by the upper support plate 410, and the wine box bottom supports located on the lower side of the upper support plate 410 are supported by the friction between the wine box bottom supports. The friction force keeps the stacking state, and then the vertical cylinder 431 drives the horizontal cylinder 432 and the dividing plate 433 to move upward, so that the dividing plate 433 is aligned with the stacking seam of the bottom support of the bottom wine box, and then the dividing plate 433 is driven to move horizontally through the horizontal cylinder 432, and the dividing plate 433 is inserted into the stacking seam of the bottom support of the bottom wine box, and then the dividing plate 433 is driven downward by the vertical cylinder 431 to drive the bottom support of the bottom wine box to be peeled off downward, and the peeled bottom support of the wine box falls to The support frame 5 is supported and lowered to the conveyor belt 2 by the support frame 5. The conveyor belt 2 conveys the bottom support of the wine box. When passing through the scanning detection device 3, a photo is taken to detect whether it is qualified. If it is unqualified, the blocking member 7 retracts to allow the bottom support of the wine box to fall out. If it is qualified, the blocking member 7 extends to allow the bottom support of the wine box to stay at the material transfer working point. After the two bottom supports of the wine boxes stay at the material transfer working point, the horizontal movement mechanism 81 drives the vertical movement mechanism 82 and the suction plate 83 to move as a whole to the top of the material transfer working point , then the vertical movement mechanism 82 drives the suction plate 83 to move downward, the suction port 830 contacts and adsorbs the bottom support of the wine box, and then the vertical mechanism drives the suction plate 83 to move upward, and the transverse movement mechanism 81 drives the vertical movement mechanism 82, the suction plate 83 and the bottom support of the wine box to move transversely to the top of the material transfer workbench 6, and finally the vertical movement mechanism 82 drives the suction plate 83 and the bottom support of the wine box to move downward, and the suction port 830 stops adsorbing, thereby placing the bottom support of the wine box on the material transfer workbench 6.
