[0045] To make the objectives, features, and advantages of the present disclosure more apparent and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0046] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0047] Referring Figures 1 - 6 As shown, an adsorption assembly according to an exemplary embodiment of the present disclosure includes a first adsorbent member 1 and a second adsorbent member 2. The first adsorbent member 1 has an annular groove 11, and a connecting portion 12 is protrudingly provided at the bottom of the annular groove 11. A through hole 121 penetrating the first adsorbent member 1 is formed in the connecting portion 12, and a ventilation hole 122 communicating with the annular groove 11 is formed in the hole wall of the through hole 121; the second adsorbent member 2 is disposed in the annular groove 11 and fixedly connected to the connecting portion 12. Wherein, the adsorption assembly has an adsorption end face 3, and adsorption holes 30 are formed on the adsorption end face 3, and the adsorption holes 30 communicate with the annular groove 11.

[0048] In this embodiment, the adsorption assembly can be disposed at the front end of the suction nozzle for adsorbing the part to be picked up. The part to be picked up can specifically be parts or components such as studs and connectors. The adsorption assembly has an adsorption end face 3 in contact with the part to be picked up and a connecting end face 13 opposite to the adsorption end face 3. The connecting end face 13 is located on the first adsorbent member 1, and a fastening portion 14 for connecting with the front end of the suction nozzle is provided on the connecting end face 13. The fastening portion 14 can specifically be a threaded structure, and the through hole 121 penetrates the connecting portion 12 and the fastening portion 14. At least one ventilation hole 122 capable of communicating with the annular groove 11 is formed in the hole wall of the through hole 121, so that air flow can pass through the ventilation hole 122 and enter the annular groove 11 from the through hole 121 or enter the through hole 121 from the annular groove 11. When the number of ventilation holes 122 is multiple, preferably, the multiple ventilation holes 122 are uniformly arranged along the circumference of the hole wall of the through hole 121 to enable the air flow to pass through evenly and stably. In the embodiments shown in the present disclosure, the number of ventilation holes 122 is taken as four as an example. Since the second adsorbent member 2 is firmly connected to the connecting portion 12, the ventilation holes 122 on the connecting portion 12 should be designed to ensure that the second adsorbent member 2 after connection does not obstruct the ventilation of the ventilation holes 122. The shape and size of the adsorption holes 30 can be adaptively designed according to actual needs to meet different adsorption requirements. The adsorption end face 3 is a plane, and the adsorption holes 30 are formed on the adsorption end face 3 and can communicate with the annular groove 11, so that air flow can pass through the adsorption assembly to ensure that the part to be picked up can be adsorbed. It can be understood that the outer contour of the first adsorbent member 1 can include, but is not limited to, a circle or a polygon.

[0049] In this embodiment, since the adsorption assembly includes a first adsorbent 1 and a second adsorbent 2, a through hole 121 is provided in the first adsorbent 1, and an air vent 122 communicating with the annular groove 11 is formed on the hole wall. When the adsorption assembly is arranged on an existing nozzle, gas can flow through the through hole 121, the annular groove 11 and the adsorption holes 30 on the adsorption end face 3 of the adsorption assembly, so as to achieve the adsorption effect. The structure is simple and the disassembly and assembly are convenient. In addition, the first adsorbent 1 and the second adsorbent 2 can be adaptively designed, and the adsorption holes 30 can also be designed according to actual needs to meet the adsorption of different sizes and types of parts to be picked up. Therefore, the adsorption assembly has strong adaptability, and the adsorption area can be flexibly adjusted to meet the adsorption requirements of different parts to be picked up, and the cost is relatively low.

[0050] In an implementable embodiment, the adsorption end face 3 includes a first end face 31 on the first adsorbent 1 and a second end face 32 on the second adsorbent 2, and the adsorption holes 30 are formed on the second end face 32.

[0051] Specifically, in an implementable embodiment, the number of the adsorption holes 30 is multiple, and the multiple adsorption holes 30 are located inside the circumferential direction of the second adsorbent 2.

[0052] In this embodiment, the adsorption holes 30 extend along the axial direction of the second adsorbent 2 and penetrate through the second adsorbent 2 to communicate with the annular groove 11. The number of the adsorption holes 30 can be one or multiple. When the number of the adsorption holes 30 is one, the adsorption hole 30 can be a continuous annular hole, or can be a hole with a shape including but not limited to a round hole, a square hole or a multi-round hole, etc. Preferably, the number of the adsorption holes 30 is multiple, and a counterbore 21 corresponding to the connecting part 12 is further provided at the second end face 32 of the second adsorbent 2. Therefore, a boss is formed around the counterbore 21, and the multiple adsorption holes 30 are arranged on the boss and are evenly distributed on the boss to ensure that the air flow can pass through evenly and stably. For example, referring to Figure 4 and Figure 5 As shown, taking the adsorption hole 30 as a round hole as an example, the number of the adsorption holes 30 is four, and the four adsorption holes 30 have the same shape and size. The adjacent two adsorption holes 30 are arranged at the same interval, and the four adsorption holes 30 are located on the same circumference. Referring to Figure 6 As shown, taking the adsorption hole 30 as a round hole as an example, the number of the adsorption holes 30 is eight, and the eight adsorption holes 30 have the same shape and size. The adjacent two adsorption holes 30 are arranged at the same interval, and the eight adsorption holes 30 are located on the same circumference.

[0053] Furthermore, in an implementable embodiment, an air vent groove 321 is formed on the second end face 32, and the air vent groove 321 communicates the adjacent two adsorption holes 30.

[0054] In this embodiment, by providing the ventilation groove 321, the air flow can be increased. It can be understood that the ventilation groove 321 is not limited to communicating adjacent two adsorption holes 30, and can also communicate multiple adsorption holes 30, and can be provided continuously or at intervals.

[0055] In an implementable embodiment, the adsorption end face 3 includes a first end face 31 on the first adsorbent 1 and a second end face 32 on the second adsorbent 2, and the adsorption holes 30 are formed on the second end face 32. The number of the adsorption holes 30 is multiple, and the multiple adsorption holes 30 communicate with the circumferential direction of the second adsorbent 2.

[0056] In this embodiment, the adsorption holes 30 communicate with the circumferential direction of the second adsorbent 2, that is, the adsorption holes 30 communicate with the inner wall of the annular groove 11. The adsorption holes 30 extend along the axial direction of the second adsorbent 2 and penetrate through the second adsorbent 2. The number of the adsorption holes 30 can be one or multiple. When the number of the adsorption holes 30 is one, the adsorption hole 30 can be a continuous annular hole, or can be a hole with a shape including but not limited to a round hole, a square hole or a multi-round hole, etc. Preferably, the number of the adsorption holes 30 is multiple, and the second end face 32 of the second adsorbent 2 further has a counterbore 21 corresponding to the connecting portion 12. Therefore, a boss is formed around the counterbore 21, and the multiple adsorption holes 30 are arranged on the boss and are evenly distributed on the boss to ensure that the air flow can pass through evenly and stably. For example, referring to Figure 7 and Figure 8 as shown, the number of the adsorption holes 30 is eight, and the eight adsorption holes 30 have the same shape and size. Adjacent two adsorption holes 30 are arranged at the same interval, and the eight adsorption holes 30 are located on the same circumference.

[0057] Furthermore, referring to Figures 9 - 11 as shown, in an implementable embodiment, a ventilation groove 321 is formed on the second end face 32, and the ventilation groove 321 communicates adjacent two adsorption holes 30.

[0058] In this embodiment, by providing the ventilation groove 321, the air flow can be increased. It can be understood that the ventilation groove 321 is not limited to communicating adjacent two adsorption holes 30, and can also communicate multiple adsorption holes 30, and can be provided continuously or at intervals. In this embodiment, taking the number of the adsorption holes 30 being four and the number of the ventilation grooves 321 being two as an example, one ventilation groove 321 communicates with two adjacent adsorption holes 30 among them, and the other ventilation groove 321 communicates with the other two adsorption holes 30.

[0059] Referring to Figures 12 - 15 as shown, in an implementable embodiment, the adsorption end face 3 includes a first end face 31 on the first adsorbent 1 and a second end face 32 on the second adsorbent 2, and the adsorption holes 30 are formed on the first end face 31 and penetrate to the bottom of the annular groove 11.

[0060] In this embodiment, the adsorption holes 30 are arranged to extend along the axial direction of the first adsorbent 1 and communicate with the annular groove 11. Specifically, the adsorption holes 30 can be selected to be opened on the inner wall of the annular groove 11; or the adsorption holes 30 can be arranged at a position avoiding the inner wall, and the annular groove 11 and the adsorption holes 30 are opened and communicated at a position close to the bottom of the annular groove 11. At this time, no hole needs to be opened on the second end face 32, and the circumferential direction of the second adsorbent 2 is attached to the inner wall of the annular groove 11. Among them, the number of the adsorption holes 30 can be one or more. When the number of the adsorption holes 30 is one, the adsorption hole 30 can be a continuous annular hole, or can be a hole with a shape including but not limited to a round hole, a square hole or a multi-round hole, etc. Preferably, the number of the adsorption holes 30 is multiple, and the multiple adsorption holes 30 are evenly distributed to ensure that the air flow can pass through evenly and stably. For example, referring to Figure 12 As shown, the number of the adsorption holes 30 is four, and the shapes and sizes of the four adsorption holes 30 are the same. The adjacent two adsorption holes 30 are arranged at the same interval, and the four adsorption holes 30 are located on the same circumference.

[0061] Referring to Figure 16 As shown, in an implementable embodiment, the adsorption end face 3 includes a first end face 31 on the first adsorbent 1 and a second end face 32 on the second adsorbent 2. Part of the adsorption holes 30 are opened on the first end face 31, and the other part of the adsorption holes 30 are opened on the second end face 32.

[0062] In this embodiment, the adsorption holes 30 defined on the first end face 31 are the first holes 301, and the adsorption holes 30 defined on the second end face 32 are the second holes 302. The first holes 301 are arranged to extend along the axial direction of the first adsorbent 1 and communicate with the annular groove 11. Specifically, the first holes 301 can be selected to be opened on the inner wall of the annular groove 11; or the first holes 301 can be arranged at a position avoiding the inner wall, and the annular groove 11 and the first holes 301 are opened and communicated at a position close to the bottom of the annular groove 11. The second holes 302 extend along the axial direction of the second adsorbent 2 and penetrate through the second adsorbent 2 to communicate with the annular groove 11. An air vent groove 321 can also be opened on the second end face 32. The air vent groove 321 communicates the adjacent two second holes 302. By providing the air vent groove 321, the air flow can be increased. The air vent groove 321 is not limited to communicating the adjacent two second holes 302, and can also communicate multiple second holes 302, and can be arranged continuously or at intervals. Among them, the number of the first holes 301 and the second holes 302 can be one or more. When the number of the first holes 301 and the second holes 302 is one respectively, the first holes 301 and the second holes 302 can be continuous annular holes respectively, or can be holes with a shape including but not limited to a round hole, a square hole or a multi-round hole, etc. Preferably, the number of the first holes 301 and the second holes 302 is multiple, and the multiple first holes 301 and the multiple second holes 302 are respectively evenly distributed to ensure that the air flow can pass through evenly and stably. For exampleFigure 16 The number of the first holes 301 shown is four, and the shapes and sizes of the four first holes 301 are the same. Adjacent two first holes 301 are arranged at the same interval, and these four first holes 301 are located on the same circumference; the number of the second holes 302 is also four, and the number of the ventilation grooves 321 is two. One ventilation groove 321 communicates with two adjacent second holes 302, and the other ventilation groove 321 communicates with the other two second holes 302.

[0063] Referring to Figure 2 、 Figure 3 and Figures 17 - 19 As shown, in an implementable embodiment, the adsorption holes 30 are formed between the outer periphery of the second adsorbent 2 and the inner wall of the annular groove 11.

[0064] In the present embodiment, the annular groove 11 may include, but is not limited to, a circular groove or a polygonal groove. When the annular groove 11 is a circular groove, the outer diameter of the second adsorbent 2 is smaller than the diameter of the circular groove, so as to form the adsorption holes 30 between the second adsorbent 2 and the circular groove. When the annular groove 11 is a polygonal groove, for example, the polygonal groove is a regular octagonal groove, the outer diameter of the second adsorbent 2 is smaller than or equal to the distance between two opposite sides of the regular octagonal groove, and the second adsorbent 2 is embedded in the regular octagonal groove and is in line contact with the inner wall of the regular octagonal groove. Therefore, the adsorption holes 30 can be formed between the outer periphery of the second adsorbent 2 and the regular octagonal groove.

[0065] In an implementable embodiment, a fastener 4 is further included, and the second adsorbent 2 and the first adsorbent 1 are locked by the fastener 4.

[0066] In the present embodiment, a counterbore 21 corresponding to the connecting portion 12 is provided at the second end face 32 of the second adsorbent 2. The fastener 4 includes a head and a locking portion. The fastener 4 may specifically be a fastener such as a screw or a bolt. The head of the fastener 4 is placed in the counterbore 21. Correspondingly, the through hole 121 of the connecting portion 12 has an internal thread section, and the locking portion is locked and connected with the internal thread section. Among them, the ventilation hole 122 can extend to the internal thread section without affecting the connection between the internal thread section and the locking portion. An adhesive layer 5 is further provided between the head and the counterbore 21. The adhesive layer 5 may specifically be a double-sided tape to prevent air from entering the gap between the second adsorbent 2 and the first adsorbent 1 connected by the fastener 4, resulting in loss of the air suction volume.

[0067] Referring to Figures 20 - 22 As shown, the present disclosure further provides a nozzle, which includes a main body 6. A passage 61 is provided in the main body 6, and the passage 61 penetrates through the main body 6. The nozzle is further provided with an adsorption assembly in any one of the above implementable embodiments, and the first adsorbent 1 is connected to the main body 6.

[0068] In this embodiment, the first adsorbing member 1 is connected to the main body 6 of the suction nozzle and is used to adsorb the member to be sucked. The member to be sucked can specifically be parts or components such as studs and connectors. The adsorption assembly has an adsorption end face 3 in contact with the member to be sucked and a connection end face 13 opposite to the adsorption end face 3. The connection end face 13 is located on the first adsorbing member 1, and a fastening portion 14 for connecting to the main body 6 is provided on the connection end face 13. The fastening portion 14 can specifically be a threaded structure. The through hole 121 penetrates through the connecting portion 12 and the fastening portion 14. Correspondingly, one end of the passage 61 of the suction nozzle close to the adsorption assembly has an internal thread section for locking with the fastening portion 14. A gasket 7 is further provided between the connection end face 13 of the first adsorbing member 1 and the main body 6. The suction nozzle is further connected to a driving assembly (not shown in the figure). The driving assembly is communicated with the passage 61 and is used to pump vacuum so that a vacuum negative pressure is formed inside and outside the suction nozzle, and thus the suction nozzle can suck the member to be sucked. Since the suction nozzle is provided with an adsorption assembly, the adsorption assembly includes a first adsorbing member 1 and a second adsorbing member 2. A through hole 121 is provided in the first adsorbing member 1, and air holes 122 communicating with the annular groove 11 are opened on the hole wall. When the adsorption assembly is arranged on the existing suction nozzle, gas can flow through the through hole 121, the annular groove 11, and the adsorption holes 30 on the adsorption end face 3 of the adsorption assembly, so as to achieve the adsorption effect. The structure is simple and the disassembly and assembly are convenient. In addition, the first adsorbing member 1 and the second adsorbing member 2 can be adaptively designed, and the adsorption holes 30 can also be designed according to actual needs to meet the adsorption of different sizes and types of members to be sucked. Therefore, the adsorption assembly has strong adaptability, the adsorption area can be flexibly adjusted to meet the adsorption requirements of different members to be sucked, and the cost is relatively low.
