Specifically, the shaft 220 and the suction assembly 100 may be fixedly connected by a threaded structure such as a screw or a bolt. The casing 210 may further have a through hole 211 communicating with the second accommodating cavity Q2, so that gas is introduced into the through hole 211, and the gas may push the rotating portion 230 to rotate, and the rotating portion 230 drives the shaft body 220 to rotate, so as to drive the suction component 100 connected with the shaft body 220 to rotate, thereby implementing actions such as adsorption and rotation on the article, improving the integrity of the rotary suction device 10, simplifying the operation steps, and improving the efficiency of production and processing. It should be noted that the driving assembly 200 may have various use manners, for example, the driving assembly 200 may be horizontally disposed so as to rotate the suction assembly 100 in a horizontal direction; or may be vertically disposed so that the suction assembly 100 rotates in a vertical direction; any other angle may be used, and the combination may be varied.
In some embodiments, the second accommodating cavity Q2 and the first accommodating cavity Q1 may have various structures, and the second accommodating cavity Q2 may be located on one side of the first accommodating cavity Q1 or may be disposed around the periphery of the first accommodating cavity Q1. Considering that the rotating portion 230 located in the second accommodating chamber Q2 may have a wide moving range, as shown in fig. 3, the second accommodating chamber Q2 may be disposed to be circumferentially disposed around the first accommodating chamber Q1 around the central axis a of the shaft 220, to provide a 360 ° rotatable space for the rotating portion 230, to increase the moving range of the rotating portion 230, and to further increase the moving range of the shaft 220 and the suction assembly 100.
In some embodiments, the second accommodation chamber Q2 may have a plurality of regions. As shown in fig. 4 and 6, the second receiving chamber Q2 may include a limiting region Q21 and a rotating region Q22, the limiting region Q21 being close to the through hole 211, the rotating region Q22 being far from the through hole 211, and the rotating part 230 being located in the rotating region Q22 such that gas introduced through the through hole 211 can pass through the limiting region Q21 to reach the rotating region Q22, pushing the rotating part 230 to rotate.

Further, the stopper 240 may have various structures. In some embodiments, as shown in fig. 4 and 5, the limiting portion 240 may have a structure with a fan-ring cross section in each plane perpendicular to the central axis a of the shaft body 220, so that two end surfaces of the limiting portion 240, that is, two opposite surfaces passing through the central axis a, can limit rotation of the rotating portion 230, and further limit rotation of the rotating portion 230 to the limiting region Q21, so as to control the rotating portion 230. It can be appreciated that two opposite surfaces of the limiting portion 240 passing through the central axis a of the shaft body 220 may be the first surface S1 and the second surface S2, respectively. The first surface S1 and the second surface S2 may be collinear, so that the rotating portion 230 may rotate 180 ° and further may drive the shaft 220 and the suction assembly to rotate 180 °. Correspondingly, the through hole 211 may include two sub through holes 211A, where the two sub through holes 211A pass through the limiting portion 240, and may be respectively communicated with the rotating area Q22 through the first surface S1 and the second surface S2, so that gas introduced into the through hole 211 may reach the rotating area Q22, and the gas introduced into the two sub through holes 211A may enable the rotating portion 230 to rotate in different directions, thereby realizing diversity of rotation directions of the rotating portion 230. Further, gas is sequentially introduced into the two sub through holes 211A, and each time the introduced gas can make the rotating part 230 limited by the limiting part 240, so that the reciprocating rotation of the rotating part 230 can be realized, further, the reciprocating rotation of the shaft body 220 and the suction assembly 100 is realized, the automation is realized, the time cost and the labor are reduced, and the production and processing efficiency is improved.

It should be noted that, the distance from the end surface of each of the limiting protrusions near to the end of the shaft 220 to the central axis a of the shaft 220 is smaller than the distance from the end surface of the rotating portion 230 far from the end of the shaft 220 to the central axis a of the shaft 220, so as to limit the rotation of the rotating portion 230.
On the other hand, the first and second limiting protrusions 241 and 242 may be detachably connected to the housing 210. For example, the first limiting protrusion 241 and the second limiting protrusion 242 may be both installed on the inner wall of the housing 210 by threaded connection, or may be connected by mortise and tenon, so that the first limiting protrusion 241 and the second limiting protrusion 242 may be replaced and assembled. Further, the mounting positions of the first limiting protrusion 241 and the second limiting protrusion 242 may be multiple, so that limiting areas Q21 with different sizes are defined, the rotating portion 230 is enabled to achieve a rotating range with different sizes, and the driving assembly 200 combined in multiple modes is achieved by matching with the detachable limiting portion 240, so that adaptability of the device is improved.

Alternatively, the number of seal rings 250 per position may be arbitrary.
In some embodiments, as shown in fig. 1, 2, and 7, the suction assembly 100 may include a suction nozzle 110 and a mounting plate 120.

The number of the suction nozzles 110 or the vacuum suction cups and other devices can be multiple, and the suction nozzles or the vacuum suction cups can be distributed at one end of the mounting plate 120 at intervals, so that the sucking stability of articles is improved. On the other hand, the plurality of suction nozzles 110 may be separately disposed at different ends of the mounting plate 120, so as to suck a plurality of articles at the same time, thereby improving efficiency.
