The second mechanical arm 3222 rotates around a horizontal axis relative to the first mechanical arm 3221, so as to achieve the purpose of adjusting the height of the adsorption assembly 323. It can be understood that the rotation of the second mechanical arm 3222 can make the suction module 323 suck the cases 100 with different heights, and can make the suction module 323 descend to suck the upper covers, and make the suction module 323 ascend to lift the sucked upper covers, so as to take the upper covers away.
The upper cover is sucked by the suction assembly 323 in a vacuum suction manner, the suction assembly 323 can suck the upper cover only by being abutted to the upper cover in a sealing manner, the second mechanical arm 3222 rotates around the horizontal axis to change the angle of the suction surface of the suction assembly 323, and in order to enable the second mechanical arm 3222 to rotate, the suction assembly 323 can still suck the upper cover, and the upper cover taking mechanism 32 further comprises an adaptor 324.
The first arm 3221 is rotatably connected to the base 321 through the adaptor 324, and the first arm 3221 is rotatably connected to the adaptor 324 around a horizontal axis to adjust an included angle between the adsorption component 323 and a horizontal plane, so that after the second arm 3222 changes the height of the adsorption component 323 and the angle of the adsorption surface, the first arm 3221 can continuously adjust the angle of the adsorption surface, and the adsorption component 323 can adsorb the upper cover. The adaptor 324 is rotatably connected to the base 321 about a vertical axis to drive the first mechanical arm 3221 and the second mechanical arm 3222 to rotate about the vertical axis.

The first conveying mechanism 11 can convey the box 100 to the bearing plate 3322, the turning assembly 332 turns, the box 100 can slide into the second conveying mechanism 12 from the bearing plate 3322, and the turning driving member is disposed on the bearing frame 331 and connected to the turning assembly 332 to drive the turning assembly 332 to turn. The baffle 3321 may prevent the box 100 from sliding off from the width direction of the conveying unit 1, and may also serve to connect the supporting plate 3322.
The four bearing plates 3322 are sequentially a first bearing plate, a second bearing plate, a third bearing plate and a fourth bearing plate, wherein the first bearing plate, the second bearing plate, the third bearing plate and the fourth bearing plate can be split structures, or the first bearing plate and the third bearing plate can be integrated, and the second bearing plate and the fourth bearing plate are integrated.
Assuming that the tilting mechanism 33 is just tilted to the position where the first carrier plate is butted with the first conveying mechanism 11, the included angle between two adjacent carrier plates 3322 is 90 °, so that the third carrier plate is just butted with the second conveying mechanism 12. At this time, the first carrying mechanism 11 can carry the box 100 to the first carrying plate, and the third carrying plate can provide the box 100 to the second carrying mechanism 12, thereby effectively providing the working efficiency. Since the first conveying mechanism 11 is higher than the second conveying mechanism 12, the first bearing plate and the third bearing plate are both inclined and the height of the first bearing plate and the height of the third bearing plate are gradually reduced from the first conveying mechanism 11 to the side of the second conveying mechanism 12, at this time, after the first conveying mechanism 11 conveys the box 100 to the first bearing plate, the box 100 automatically moves to the first bearing plate under the action of self gravity, and since the second bearing plate is arranged between the first bearing plate and the third bearing plate, the box 100 can be effectively prevented from directly falling into the second conveying mechanism 12 without being overturned in the overturning process of the overturning mechanism 33. Meanwhile, the box 100 on the third carrying plate is turned over 180 degrees in the vertical direction with respect to the box 100 on the first carrying plate, and the box 100 automatically slides to the second conveying mechanism 12 under the action of its own weight.
