For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0060] In the description of the present application, it should be understood that the "upper", "lower" and the like described in the embodiments of the present application are described from the angle shown in the drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when referring to an element connected to another element "on" or "below", it can not only be directly connected to another element "on" or "below", but also indirectly connected to another element "on" or "below" through an intermediate element.

[0061] As Figure 1 and Figure 2As shown, the embodiment of the present application provides a suction cup assembly 3 for picking up and placing articles such as glass slides, which comprises a communicating member 31, a flexible member 32 and a rigid suction cup 33. The communicating member 31 is provided with an air passage, and the communicating member 31 is used to connect an external negative pressure assembly (for example, a negative pressure pump or the like), so that the suction cup assembly 3 can freely realize suction picking up and loose placing; the rigid suction cup 33 is arranged at one end of the communicating member 31, and the rigid suction cup 33 forms a suction port of the suction cup assembly 3. Since the rigid suction cup 33 is not prone to deformation, it can effectively control the suction area and suction strength, prevent the suction cup assembly 3 from being adhered to the surface of the article, realize the rapid picking up and placing of the article, and also enable the suction cup assembly 3 to form reliable contact with the article, prevent the article from being deformed and causing the suction to be not firm, and realize the reliable movement of the article; a gap is arranged between the rigid suction cup 33 and the communicating member 31, the flexible member 32 is arranged between the communicating member 31 and the rigid suction cup 33, the flexible member 32 is sealingly connected to the communicating member 31, and the flexible member 32 is sealingly connected to the rigid suction cup 33, that is, the rigid suction cup 33 and the communicating member 31 are in communication with each other through the flexible member 32, so that the rigid suction cup 33, the flexible member 32 and the communicating member 31 form a sealed gas passage, and the reliable negative pressure state of the rigid suction cup 33 is ensured. Moreover, since the gap is arranged between the rigid suction cup 33 and the communicating member 31, the deformation constraint of the flexible member 32 is reduced, so that the rigid suction cup 33 can be flexibly adjusted according to the needs, such as expansion and contraction buffering or tilting, which can prevent the surface of the article from being damaged due to excessive stress, and can ensure that the angle of the suction cup assembly 3 is adapted to the surface of the article, so as to form reliable suction to the article.

[0062] Further, the flexible member 32 is arranged in an annular sheet structure extending along the radial direction of the communicating member 31, and the communicating member 31 and the rigid suction cup 33 form an annular gap along the radial direction; the inner circle of the flexible member 32 is connected to the communicating member 31, and the outer circle of the flexible member 32 is connected to the rigid suction cup 33. On the one hand, the softness of the flexible member 32 can be increased as much as possible, so that the flexible member 32 can be deformed according to the needs, and the rigid suction cup 33 can form gentle and reliable contact with the surface of the article; on the other hand, the radial deformation of the flexible member 32 can be effectively limited, so as to reduce the adverse effects of the shaking of the rigid suction cup 33. In addition, the structure of the flexible member 32 can be simplified, so as to simplify the production process and reduce the production cost.

[0063] In other embodiments, the flexible member 32 can also be arranged in an annular columnar structure, the communicating member 31 and the rigid suction cup 33 are arranged in an axial gap, one end of the flexible member 32 is connected to the communicating member 31, and the other end of the flexible member 32 is connected to the rigid suction cup 33. The flexible member 32 can also be arranged in an annular conical structure, the communicating member 31 and the rigid suction cup 33 form an annular gap along the radial direction and are arranged in an axial gap, the smaller end of the flexible member 32 is connected to the communicating member 31, and the larger end of the flexible member 32 is connected to the rigid suction cup 33.

[0064] The communication member 31 is provided in a columnar structure, and the air passage extends along the axial direction of the communication member 31. The communication member 31 can be provided as a rigidly connected component, or can be provided with a spring or other buffering member.

[0065] Further, the communication member 31 comprises a main body portion 311 and a connecting head 312 which are detachably connected. The connecting head 312 and the main body portion 311 can be connected to each other in a threaded fitting manner or a snap fitting manner, for example. The flexible member 32 is clamped between the connecting head 312 and the main body portion 311, so as to facilitate the dismounting and replacement of the flexible member 32 and prevent the flexible member 32 from being worn or aged to cause a poor seal. It can be understood that the flexible member 32 and the communication member 31 can also be connected to each other in a non-detachable manner such as bonding or injection molding.

[0066] Further, the rigid suction cup 33 comprises a suction cup body 331 provided in an annular structure. The inner side of the suction cup body 331 is provided with a flange 331a. The flexible member 32 is inserted into the inner cavity of the suction cup body 331 and overlapped with the flange 331a, so as to increase the fitting area of the flexible member 32 and the suction cup body 331 and thus increase the reliability of the connection therebetween.

[0067] Specifically, the inner side of the flange 331a forms a mounting hole, the radial dimension of the mounting hole is greater than the radial dimension of the communication member 31, so that an annular gap is formed between the communication member 31 and the mounting hole. The radial dimension of the flexible member 32 is greater than the radial dimension of the mounting hole, so that an overlapping fitting area is formed between the flexible member 32 and the flange 331a, thereby increasing the fitting area of the flexible member 32 and the suction cup body 331. The radial dimension of the flexible member 32 is not greater than the inner cavity of the suction cup body 331, so as to avoid the flexible member 32 interfering with the side wall of the suction cup body 331, affecting the flatness of the flexible member 32, and causing the flexible member 32 and the rigid suction cup 33 to seal poorly.

[0068] Further, the rigid suction cup 33 further comprises a locking member 332 which is detachably connected to the inner side of the suction cup body 331, for example, the locking member 332 can be connected to the suction cup body 331 in a threaded fitting manner or a snap fitting manner. The flexible member 32 is clamped between the flange 331a and the locking member 332, and the flexible member 32 is pressed by the locking member 332, which can prevent the flexible member 32 and the rigid suction cup 33 from being separated from each other and can also ensure that the flexible member 32 forms a reliable flattened state, thereby improving the sealing effect.

[0069] Further, a part of the locking member 332 extends to the outside of the rigid suction cup 33 to form a suction port, which can facilitate the mounting and dismounting operation of the locking member 332 and can also reduce the area of the suction port, thereby preventing the suction cup assembly 3 from being adhered to the surface of an object.

[0070] Further, the rigid suction cup 33 is provided with a tapered structure 33a, for example, at least one section of the locking member 332 is provided with the tapered structure 33a; and the radial dimension of the tapered structure 33a gradually decreases in the direction away from the communication member 31. By providing the tapered structure 33a, the inner cavity of the rigid suction cup 33 is formed with a first cavity 33b with a larger radial dimension near the communication member 31, so as to increase the deformation space of the flexible member 32, thereby increasing the active adjustment range of the rigid suction cup 33; and the inner cavity of the rigid suction cup 33 is formed with a second cavity 33c with a smaller radial dimension away from the communication member 31, so as to form a larger gas flow speed at the suction port, thereby forming a lower negative pressure state and improving the reliability of the article suction.

[0071] Further, the suction cup assembly 3 provided by the embodiment of the present application further comprises a micro-motion assembly 34, the communication member 31 is fixedly connected to the end of the micro-motion assembly 34, and the rigid suction cup 33 is driven to move axially by the micro-motion assembly 34 to complete the suction, lifting and placing actions, which can improve the accuracy of the action of the rigid suction cup 33 and reduce the impact of the rigid suction cup 33 on the surface of the article.
