Currently, typical vacuum suction devices include components such as vacuum generators and suction cups. The vacuum generator uses a high-speed positive pressure air flow to generate a vacuum at the suction port and sucks objects through the suction cup.

[0010] As a further solution of the present utility model: One side of the adapter base facing the suction cup bottom cover is provided with a second counterbore. The large hole diameter of the second counterbore is larger than the diameter of the pneumatic component, so that the pneumatic component is movably connected in the second counterbore; The small hole diameter of the second counterbore is smaller than the diameter of the pneumatic component, so that the pneumatic component can close or open the small hole of the second counterbore under the drive of the external negative pressure air flow; One side of the suction cup bottom cover facing the adapter base is provided with a second through hole, and the second through hole and the second counterbore are communicated with each other to form an air flow channel; The diameter of the second through hole is smaller than the diameter of the pneumatic component, so as to limit the pneumatic component.

The small hole diameter of the third counterbore is smaller than the diameter of the pneumatic component, and the large hole diameter of the third counterbore is larger than the diameter of the pneumatic component; One side of the adapter base facing the suction cup bottom cover is provided with a fourth counterbore.

The matrix suction cups can synchronously suck or adsorb multiple points in the adsorption plane. When the adsorption fails at local points due to the structural holes of the product, other adsorption points can still suck the product, so as to perform the transfer work, thereby improving the versatility of the suction cup assembly, saving the time for replacing the suction cup assembly in the production process, improving the production efficiency, and at the same time, the cost of customizing the suction cup can be saved, and the production cost can be reduced.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 to 7 , in the embodiment of the present invention, a matrix sucker assembly includes a sucker cylinder body 10 and an adsorption assembly 30 that are in gas path communication with each other. One end of the sucker cylinder body 10 is connected to an external vacuum generating device to supply negative pressure air flow, and the other end is connected to the adsorption assembly 30. At least one adsorption assembly 30 is fixedly connected to the sucker cylinder body 10 and forms a gas path communication with the sucker cylinder body 10; the adsorption assembly 30 is provided with at least two vacuum suction nozzles 31. One end of the vacuum suction nozzle 31 is connected to the adsorption assembly 30, and the other end forms a free end for sucking an external material 70; a pneumatic component 33 is arranged in the air flow channel 32 inside the adsorption assembly 30. Driven by the external negative pressure air flow, the pneumatic component 33 closes or opens the air flow channel 32, thereby closing or opening the sucking operation of the vacuum suction nozzle 31.

[0035] Specifically, the pneumatic component 33, preferably, is a circular ball made of aluminum material, so that it is convenient to move freely in the air flow channel 32, and at the same time, the outer wall of its spherical body can be used to form a blocked closed state for the air flow channel 32.

[0036] When using the matrix suction cup assembly to perform a suction operation on the external material 70, multiple vacuum nozzles 31 in the matrix can simultaneously perform vacuum suction on the external material 70. When a part of the vacuum nozzles 31 corresponds to the avoidance position 71 of the external material 70, that is, the sucked part of the vacuum nozzle 31 is empty, the lower part of the vacuum nozzle 31 is in a state of being connected to the atmosphere, and the upper part of the vacuum nozzle 31 is connected to the air flow channel 32. The air flow channel 32 is connected to the air guide space 41 through the air guide hole 42, so as to generate a negative pressure air flow under the drive of an external vacuum generating device.

[0037] And the pneumatic component 33 that is exactly located in the air flow channel 32 and can move freely is affected by the negative pressure air flow on the side facing the adapter base 40. In the state where the other side is connected to the atmosphere, it is pushed by the atmospheric pressure, so that the pneumatic component 33 can move towards the adapter base 40 and block the small hole of the fourth counterbore 53 on the adapter base 40, thereby preventing the air flow from continuing to flow into the air guide space 41 of the adapter base 40. This is equivalent to closing the vacuum nozzle 31 here, avoiding the continuous consumption of negative pressure air flow by the vacuum nozzle 31 in the avoidance position 71, and reducing the suction pressure of the entire suction cup assembly.

[0038] Secondly, another part of the vacuum nozzles 31 exactly corresponds to the non-avoidance position 71 of the external material 70, so as to perform a suction operation on the external material 70. Since the sucked external material 70 also closes the vacuum nozzle 31, air cannot continue to flow into the interior of the vacuum nozzle 31. Therefore, the atmospheric pressure that continuously provides extrusion and pushing to the pneumatic component 33 cannot be provided, so that the pneumatic component 33 cannot block the air flow channel 32, and the air path between the vacuum nozzle 31, the air flow channel 32, the air guide hole 42 and the air guide space 41 is continuously kept connected. Furthermore, the vacuum nozzle 31 can perform continuous suction operation on the external material 70, achieving the effect that the external material 70 with various structures, different shapes or different avoidance positions 71 can be sucked.

[0039] As Figure 1 and Figure 2 shown, preferably, the adsorption assembly 30 is provided with an adapter base 40 and a suction cup bottom cover 60 that are connected in an air path. One side of the adapter base 40 is fixedly connected to the suction cup cylinder block 10, and the other side is fixedly connected to the suction cup bottom cover 60. One side of the suction cup bottom cover 60 is fixedly connected to the adapter base 40, and N vacuum nozzles 31 are installed on the other side. The installation positions of the N vacuum nozzles 31 form a matrix structure, so as to perform an adsorption operation of synchronous suction of the N vacuum nozzles 31 on the external material 70.

[0040] Specifically, in order to form a matrix suction cup assembly, preferably, N is greater than 2. For example, a set of adsorption components 30 can be provided with 59 vacuum suction nozzles 31. Then, multiple sets of adsorption components 30 can be installed on a suction cup cylinder body 10, such as installing two sets of adsorption components 30, so as to form a matrix suction cup assembly with 118 vacuum suction nozzles 31. And by closing the air flow channels 32 corresponding to the vacuum suction nozzles 31 at the avoidance positions 71 of the external material 70 through the pneumatic component 33, the air guide space 41 of the adapter base 40 can evenly disperse the pressure of the negative pressure air flow to the remaining open air flow channels 32, so that the vacuum suction nozzles 31 corresponding to the open air flow channels 32 can generate relatively uniform adsorption force, and thus be converted into corresponding adsorption surfaces to perform adsorption operation on the external material 70.

[0041] In the first embodiment, as Figure 4 shown, preferably, on one side of the suction cup bottom cover 60 facing the adapter base 40, there is a first counterbore 61. The diameter of the small hole of the first counterbore 61 is smaller than the diameter of the pneumatic component 33, and the diameter of the large hole of the first counterbore 61 is larger than the diameter of the pneumatic component 33, so that the pneumatic component 33 is movably connected in the first counterbore 61; on one side of the adapter base 40 facing the suction cup base, there is a first through hole 51. The first through hole 51 and the first counterbore 61 communicate with each other to form an air flow channel 32; the diameter of the first through hole 51 is smaller than the diameter of the pneumatic component 33, so that the pneumatic component 33 can close or open the first through hole 51 under the drive of the external negative pressure air flow.

[0042] Specifically, in the first embodiment, the counterbore can be arranged inside the suction cup bottom cover 60, and the adapter base 40 only needs to be provided with a simple through hole. In order to enable the pneumatic component 33 to move correspondingly under the drive of the negative pressure air flow and block the first through hole 51, thereby closing the corresponding vacuum suction nozzle 31, the first through hole 51 and the first counterbore 61 can be arranged coaxially.

[0043] Secondly, the small hole part of the first counterbore 61 mainly plays a role in limiting the pneumatic component 33 to prevent it from falling off; while the large hole part has a certain depth and can form a space for the pneumatic component 33 to move freely, that is, the pneumatic component 33 is driven by the negative pressure air flow at the large hole part and flips and rolls freely. The vacuum suction nozzle 31 is installed on the suction cup bottom cover 60 and is in a communicating state with the small hole of the first counterbore 61.

[0044] In the second embodiment, as Figure 5As shown, preferably, a second counterbore 52 is provided on one side of the adapter base 40 facing the suction cup bottom cover 60. The diameter of the large hole of the second counterbore 52 is larger than the diameter of the pneumatic component 33, so that the pneumatic component 33 is movably connected within the second counterbore 52; the diameter of the small hole of the second counterbore 52 is smaller than the diameter of the pneumatic component 33, so that the pneumatic component 33 can close or open the small hole of the second counterbore 52 under the drive of the external negative pressure air flow; a second through hole 62 is provided on one side of the suction cup bottom cover 60 facing the adapter base 40. The second through hole 62 and the second counterbore 52 communicate with each other to form an air flow channel 32; the diameter of the second through hole 62 is smaller than the diameter of the pneumatic component 33, so as to form a limiting effect on the pneumatic component 33.

[0045] Specifically, in the second embodiment, the counterbore can be provided on the adapter base 40, and the suction cup bottom cover 60 only needs to be provided with a simple through hole. Similarly, the second counterbore 52 and the second through hole 62 can be coaxially arranged. A part of the inner wall of the second through hole 62 can support the pneumatic component 33 to prevent the pneumatic component 33 from falling off from the second through hole 62. And the large hole part of the second counterbore 52 has a certain depth, so as to form a space for the free movement of the pneumatic component 33. The vacuum suction nozzle 31 is installed on the suction cup bottom cover 60 and is in communication with the second through hole 62.

[0046] In the third embodiment, as Figure 3 and Figure 6 shown, preferably, a third counterbore 63 is provided on one side of the suction cup bottom cover 60 facing the adapter base 40. The diameter of the small hole of the third counterbore 63 is smaller than the diameter of the pneumatic component 33, and the diameter of the large hole of the third counterbore 63 is larger than the diameter of the pneumatic component 33; a fourth counterbore 53 is provided on one side of the adapter base 40 facing the suction cup bottom cover 60. The diameter of the small hole of the fourth counterbore 53 is smaller than the diameter of the pneumatic component 33, and the diameter of the large hole of the fourth counterbore 53 is larger than the diameter of the pneumatic component 33. The third counterbore 63 and the fourth counterbore 53 communicate with each other to form an air flow channel 32; and the third counterbore 63 and the fourth counterbore 53 are coaxially arranged, and the space formed between the large hole of the third counterbore 63 and the large hole of the fourth counterbore 53 is available for the free movement of the pneumatic component 33, so that the pneumatic component 33 can close or open the small hole of the fourth counterbore 53 under the drive of the external negative pressure air flow.

[0047] Specifically, in the third embodiment, counterbores can be respectively provided between the adapter base 40 and the suction cup bottom cover 60, and the large holes of the third counterbore 63 and the fourth counterbore 53 are respectively fitted with each other to form a space for the pneumatic component 33 to move freely. Thus, the pneumatic component 33 can be driven by the external negative pressure air flow to perform corresponding flipping and rolling, and block the small hole of the fourth counterbore 53, thereby closing the corresponding vacuum suction nozzle 31. Similarly, the vacuum suction nozzle 31 is installed on the suction cup bottom cover 60 and is in a communicating state with the small hole of the third counterbore 63.

[0048] As Figure 6 shown, preferably, the side wall of the large hole of the fourth counterbore 53 protrudes from the adapter base 40 to form an annular protrusion 54, and the annular protrusion 54 can be embedded in the large hole of the third counterbore 63, so that the outer wall of the annular protrusion 54 abuts against the inner wall of the large hole of the third counterbore 63 and forms a sealed connection.

[0049] Specifically, in order to prevent air leakage between the third counterbore 63 and the fourth counterbore 53, the annular protrusion 54 can be provided to form an interference fit with the inner wall of the large hole of the third counterbore 63 and achieve a sealing effect. Since the adapter base 40 and the suction cup bottom cover 60 are respectively provided with a plurality of corresponding counterbores, and each counterbore is equipped with a corresponding vacuum suction nozzle 31, in order to seal the connection part of each counterbore, preferably, the annular protrusion 54 is provided at the connection part of the counterbores, thereby optimizing the sealing performance.

[0050] As Figure 3 、 Figure 4 and Figure 7 shown, preferably, the upper part of the side of the adapter base 40 facing the suction cup cylinder body 10 is provided with a gas guiding space 41, and the lower part thereof is provided with a plurality of gas guiding holes 42. The plurality of gas guiding holes 42 are respectively communicated with a plurality of vacuum suction nozzles 31, and the gas guiding space 41 is respectively communicated with the suction cup cylinder body 10 and the plurality of gas guiding holes 42. A first groove 43 is provided at the edge part of the gas guiding space 41, and a first sealing ring 44 is provided in the first groove 43.

[0051] Specifically, the gas guiding space 41 is used to disperse and supply the negative pressure air flow provided by the suction cup cylinder body 10 to the plurality of gas guiding holes 42, so that the plurality of gas guiding holes 42 have uniform air flow pressure, thereby providing a better sucking operation for the external material 70. The first sealing ring 44 is used to form a sealed connection for the connection part between the adapter base 40 and the suction cup cylinder body 10 to prevent air leakage between them.

[0052] As Figure 3 、 Figure 5 and Figure 7As shown, preferably, the suction cup cylinder 10 is provided with a lower cylinder 20 and an upper cylinder 11 fixed to each other, the upper cylinder 11 is provided with an airflow space 13 on the inner side, and a straight-through air nozzle 12 is provided on the outer side thereof, one end of the straight-through air nozzle 12 is connected to the airflow space 13, and the other end thereof is connected to an external vacuum generating device, so as to generate a negative pressure airflow in the airflow space 13 and form a negative pressure state; the lower cylinder 20 is provided with an airflow hole 21, and the two ends of the airflow hole 21 are respectively connected to the airflow space 13 and the air guide space 41. A second groove 14 is provided at the edge of the airflow space 13, and a second sealing ring 15 is provided in the second groove 14.

[0053] Specifically, in order to simplify the complexity of the airflow pipeline in the suction cup cylinder 10, an airflow space 13 can be directly set in the upper cylinder 11, so that the airflow space 13 can correspond to multiple adsorption components 30 and provide corresponding negative pressure airflow. Similarly, a corresponding airflow hole 21 can be set at the position of the lower cylinder 20 corresponding to the adsorption component 30, and one airflow hole 21 can be used to correspond to one adsorption component 30, so that the airflow hole 21 can be connected to the air guide space 41 of the adsorption component 30, and a negative pressure airflow is carried out, thereby forming a corresponding negative pressure to perform the suction operation. The second sealing ring 15 can form a sealed connection between the connecting part of the upper cylinder 11 and the lower cylinder 20 to prevent air leakage between each other.

[0054] Secondly, in order to fix the lower cylinder 20 and the upper cylinder 11, a cylinder fixing bolt 22 can also be provided, and the upper cylinder 11 is provided with a corresponding threaded hole, so that the lower cylinder 20 can be firmly connected to the upper cylinder 11. Similarly, in order to fix the adapter base 40 and the suction cup bottom cover 60, a bottom cover locking bolt 64 can also be provided. Figure 4 As shown, it is preferred to use the bottom cover locking bolts 64 to fix the adapter base 40 and the suction cup bottom cover 60 to the lower cylinder body 20.

[0055] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
