Description

Technical Field

[0001] This application relates to the field of adsorption equipment technology, and more particularly to an adsorption device. Background Technology

[0002] In current product processing, a vacuum valve creates a vacuum through a vacuum passage to evacuate multiple adsorption holes, allowing the adsorption element with multiple adsorption holes to adsorb the product being processed, thus ensuring stable product processing. However, when adsorbing products, some irregularly shaped products or improper placement may result in some adsorption holes not being completely covered. This allows external atmosphere to enter the vacuum passage through the partially covered adsorption holes, disrupting the vacuum state of all adsorption holes on the adsorption element and reducing the adsorption stability of the product. Utility Model Content

[0003] In view of the above situation, it is necessary to provide an adsorption device to improve the adsorption stability of the workpiece.

[0004] Some embodiments of this application provide an adsorption device, including a connecting component, a supporting component, and multiple sets of adsorption components. The connecting component includes a connecting member, an air extraction member and a pressure relief member respectively connected to the connecting member, with the air extraction member and the pressure relief member respectively connected to the connecting member. The supporting component is detachably connected to the connecting member and has multiple evenly arranged connecting slots, and the supporting component is configured to support a workpiece. Multiple adsorption components are connected to a connecting component and correspond one-to-one with multiple connecting slots. Each adsorption component includes a valve body detachably connected to the connecting component, an elastic element abutting against the valve body, and a sealing element abutting against the elastic element. The valve body is provided with a receiving slot, which is connected to the connecting component and the corresponding connecting slot. The receiving slot is configured to adsorb the workpiece under the conduction of the suction component and release the workpiece under the conduction of the pressure relief component. The elastic element is located in the receiving slot, and the sealing element is slidably located in the receiving slot and is away from the connecting component relative to the elastic element. The sealing element and the valve body abut against the two ends of the elastic element, respectively. The sealing element is configured to compress the elastic element and seal the receiving slot under negative pressure.

[0005] In some embodiments, the receiving groove includes a conical groove and a through groove that are connected to each other. The conical groove is located away from the connecting member relative to the through groove. The cross-sectional area of ​​the conical groove in the radial direction of the through groove decreases along the direction of the valve body toward the connecting member. The through groove is connected to the connecting member.

[0006] In some embodiments, the valve body includes a main body and a threaded body. The main body passes through the bearing assembly along the direction of the connecting member towards the valve body and communicates with a corresponding connecting groove, with a tapered groove disposed on the main body. One end of the threaded body is connected to the main body, and the other end of the threaded body is threadedly connected to the connecting member, with a through groove disposed on the threaded body.

[0007] In some embodiments, the valve body further includes a first sealing body and a second sealing body. The first sealing body is sleeved on the threaded body, and its two ends abut against the main body and the connecting member, respectively. The second sealing body surrounds the end of the tapered groove away from the connecting member, and its two ends abut against the main body and the supporting assembly, respectively.

[0008] In some embodiments, each adsorption assembly further includes a filter element embedded in the valve body at the end away from the connecting element and located between the receiving groove and the connecting groove.

[0009] In some embodiments, the connecting component further includes a pressure detection element disposed on one side of the connecting component and connected to the connecting component, and the pressure detection element is connected to the air extraction element and the pressure relief element respectively.

[0010] In some embodiments, the support assembly includes a fixing member and a support member. The fixing member is detachably connected to the connecting member. The fixing member has multiple receiving slots, each corresponding to a valve body of a set of adsorption assemblies. Each receiving slot penetrates the fixing member and accommodates a corresponding valve body. The support member is located on the side of the fixing member opposite to the connecting member and is detachably connected to the fixing member. The support member has multiple through slots, each corresponding to a receiving slot. Each through slot penetrates the support member and communicates with a corresponding receiving slot to form a connecting slot.

[0011] In some embodiments, the carrier further includes a positioning member disposed on the side of the carrier opposite to the fixing member, and the positioning member is configured to position the external removal member.

[0012] In some embodiments, the connecting component includes a support member, one end of which is connected to the connecting component, and the other end of which abuts against the bearing component to support the bearing component.

[0013] In some embodiments, the connecting assembly further includes a seal disposed around the valve body of the plurality of adsorption assemblies and on the side of the connecting assembly facing the carrier assembly, with the two ends of the seal abutting against the connecting assembly and the carrier assembly, respectively.

[0014] When the aforementioned adsorption device adsorbs a workpiece, the air extraction component can extract air through multiple sets of adsorption components and corresponding connecting slots to adsorb the workpiece to the carrying component. When a connecting slot is not completely covered by the workpiece, the sealing component corresponding to the not-completely-covered connecting slot compresses the elastic component to the wall of the receiving slot under negative pressure to seal the corresponding receiving slot, preventing external atmosphere from entering the connecting component and disrupting the vacuum state of other adsorption components. This ensures that the other completely covered connecting slots stably adsorb the workpiece, thereby improving the adsorption stability of the workpiece. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0024] Please see Figure 1 and Figure 2 This application provides an adsorption device 100, which includes a connecting component 10, a supporting component 20 connected to the connecting component 10, and multiple adsorption components 30 respectively connected to the connecting component 10. The adsorption device 100 is used to stably adsorb workpiece 200 to improve the adsorption stability of workpiece 200.

[0025] Please see Figure 1 and Figure 2 The connecting component 10 includes a connecting member 11 detachably connected to the supporting component 20, an air extraction member 12 communicating with the connecting member 11, a pressure relief member 13 disposed on one side of the air extraction member 12 and communicating with the connecting member 11, a pressure detection member 14 communicating with the air extraction member 12 and the pressure relief member 13 respectively, a support member 15 connected to the connecting member 11, and a sealing member 16 abutting against the connecting member 11. The connecting member 11 is generally plate-shaped and communicates with the air extraction member 12, the pressure relief member 13, the pressure detection member 14, and the multiple adsorption components 30 respectively. The support member 15 is generally cylindrical, with one end connected to the connecting member 11 and the other end abutting against the supporting component 20. The sealing member 16 is arranged around the multiple adsorption components 30 and is disposed on the side of the connecting member 11 facing the supporting component 20, with both ends of the sealing member 16 abutting against the connecting member 11 and the supporting component 20 respectively. The connecting component 11 can be any connecting part, connecting plate, or connecting body that is connected to the air extraction component 12, the pressure relief component 13, the pressure detection component 14, and the multiple adsorption components 30 respectively. The air extraction component 12 can be an air extraction valve, the pressure relief component 13 can be a pressure relief valve, the pressure detection component 14 can be a pressure gauge, and the sealing component 16 can be a sealing ring.

[0026] When adsorbing workpiece 200, the suction unit 12 draws air through the connecting member 11 and multiple sets of adsorption components 30 to adsorb workpiece 200 to the carrying component 20. When releasing workpiece 200, the pressure relief unit 13 releases pressure through the connecting member 11 and multiple sets of adsorption components 30 to release the adsorbed workpiece 200, thereby achieving stable adsorption or release of workpiece 200. The pressure detection unit 14 monitors the negative pressure state of the connecting member 11 in real time when adsorbing workpiece 200, so that the operator can adjust the placement position of workpiece 200 and inspect the adsorption device 100 in a timely manner to ensure the adsorption device is functioning properly. The adsorption device 100 stably adsorbs the workpiece 200, thereby improving the adsorption stability of the workpiece 200; the support member 15 supports the carrier component 20, which can provide support for the carrier component 20 and prevent the carrier component 20 from deforming or displacing when adsorbing the workpiece 200 or when the workpiece 200 is processed, thereby ensuring the adsorption stability and processing stability of the workpiece 200; the sealing member 16 seals the connecting member 11 and the carrier component 20, preventing external atmosphere from damaging the overall sealing of the adsorption device 100 between the two, thereby improving the adsorption stability of the adsorption device 100.

[0027] Please see Figure 1 , Figure 2 and Figure 3 The supporting component 20 includes a fixing member 21 detachably connected to the connecting member 11, a supporting member 22 detachably connected to the fixing member 21, and a positioning member 24 connected to the supporting member 22. The fixing member 21 is generally plate-shaped and detachably connected to the connecting member 11. The fixing member 21 has multiple receiving slots 211, each corresponding to a set of adsorption components 30. Each receiving slot 211 penetrates the fixing member 21 and accommodates the corresponding adsorption component 30. The supporting member 22 is also generally plate-shaped and is located on the side of the fixing member 21 away from the connecting member 11 and detachably connected to the fixing member 21. The supporting member 22 has multiple through slots 221, each corresponding to a receiving slot 211. Each through slot 221 penetrates the supporting member 22 and communicates with the corresponding receiving slot 211 to form a connecting slot 23. The multiple connecting slots 23 are evenly arranged. The positioning element 24 is generally rod-shaped and is located on the side of the bearing element 22 opposite to the fixing element 21. The positioning element 24 is configured to position an external transfer element. The external transfer element can be a robotic arm.

[0028] By setting the carrier 22 and the fixing member 21 to be detachably connected, the fixing member 21 and the carrier 22 form a split structure, which makes it easy to assemble multiple adsorption components 30 to the carrier component 20 and the connecting component 10, thereby improving the ease of assembly and disassembly; the receiving groove 211 and the through groove 221 are connected to form a connecting groove 23, so that the connecting groove 23 is connected to the corresponding adsorption component 30, ensuring that the adsorption component 30 stably adsorbs the workpiece 200 through the connecting groove 23, thereby improving the adsorption stability of the workpiece 200; the positioning member 24 positions the external transfer member so that the external transfer member corresponds to the carrier 22, which is conducive to the external transfer member accurately transferring the processed workpiece 200.

[0029] Please see Figure 2 , Figure 3 and Figure 4 Multiple adsorption components 30 correspond one-to-one with multiple connecting slots 23. Each adsorption component 30 includes a valve body 31 detachably connected to the connecting member 11, an elastic member 32 abutting against the valve body 31, a sealing member 33 abutting against the elastic member 32, and a filter member 34 embedded in the valve body 31. The valve body 31 is generally cylindrical and is located in a corresponding receiving slot 211. The valve body 31 has a receiving slot 311 extending axially along the valve body 31. The receiving slot 311 is connected to the connecting member 11 and the corresponding connecting slot 23, respectively. The receiving slot 311 is configured to adsorb the workpiece 200 when the suction member 12 is activated, and to release the workpiece 200 when the pressure relief member 13 is activated. The elastic element 32 is disposed in the receiving groove 311. The sealing element 33 is generally block-shaped and slidably disposed in the receiving groove 311, away from the connecting member 11 relative to the elastic element 32. The sealing element 33 and the valve body 31 respectively abut against the two ends of the elastic element 32. The filter element 34 is generally disc-shaped and is embedded in the end of the valve body 31 away from the connecting member 11, located between the receiving groove 311 and the connecting groove 23. The elastic element 32 can be a spring, and the filter element 34 can be any filter plate, filter body, or similar filter part capable of filtering debris and dirt.

[0030] The valve body 31 is connected to the connecting member 11 and the connecting groove 23 through its receiving groove 311. When the adsorption device 100 adsorbs the workpiece 200, the receiving groove 311 forms a negative pressure under the conduction of the suction member 12 to stably adsorb the workpiece 200. When the adsorption device 100 releases the workpiece 200, the receiving groove 311 breaks the negative pressure under the conduction of the pressure relief member 13 to stably release the workpiece 200, thereby achieving stable adsorption and stable release of the workpiece 200. When the connecting groove 23 is not completely covered by the workpiece 200, the valve body 31 continuously suctions air under the conduction of the suction member 12, and a pressure difference is formed on both sides of the sealing member 33, causing the sealing member 33 to compress the elastic member 32 to the groove wall of the receiving groove 311 under the action of negative pressure. The sealing of the receiving groove 311 prevents external atmosphere from entering the connecting member 11 and disrupting the vacuum state of other connecting grooves 23 and the adsorption assembly 30, ensuring that the other completely covered adsorption holes stably adsorb the workpiece 200, thereby improving the adsorption stability of the workpiece 200. At the same time, when the adsorption device 100 releases the workpiece 200, the elastic member 32 pushes the sealing member 33 away from the connecting member 11, so that the adsorption device 100 can repeat the adsorption operation. The filter member 34 is provided between the receiving groove 311 and the connecting groove 23, which can filter the debris and dirt of the product during the processing of the workpiece 200, preventing debris and dirt from entering the valve body 31 and clogging the valve body 31, which helps to extend the service life of the adsorption assembly 30.

[0031] Please see Figure 3 and Figure 4 The valve body 31 includes a main body 312 passing through the receiving groove 211, a threaded body 313 threadedly connected to the connecting member 11, a first sealing body 314 sleeved on the threaded body 313, and a second sealing body 315 abutting against the main body 312. The main body 312 is generally cylindrical and communicates with the corresponding connecting groove 23. The main body 312 has a tapered groove 3121. The threaded body 313 is generally rod-shaped and has a through groove 3131. One end of the threaded body 313 is connected to the main body 312, and the other end is threadedly connected to the connecting member 11. The cross-sectional area of ​​the tapered groove 3121 in the radial direction of the through groove 3131 decreases along the direction from the valve body 31 to the connecting member 11. The tapered groove 3121 is farther away from the connecting member 11 relative to the through groove 3131. The tapered groove 3121 and the through groove 3131 communicate to form the receiving groove 311. The first sealing body 314 is generally ring-shaped and is fitted onto the threaded body 313. Both ends of the first sealing body 314 abut against the main body 312 and the connecting member 11, respectively. The second sealing body 315 is also generally ring-shaped and surrounds the end of the tapered groove 3121 away from the connecting member 11. Both ends of the second sealing body 315 abut against the main body 312 and the fixing member 21, respectively. Both the first sealing body 313 and the second sealing body 315 can be sealing rings.

[0032] By setting the threaded body 313 to be threadedly connected to the connecting member 11, it is easy to assemble the valve body 31 and other parts of the adsorption assembly 30 to the connecting member 11, which facilitates the disassembly and maintenance of a single adsorption assembly 30, thereby improving the disassembly and assembly efficiency. By setting the first sealing body 314 and the second sealing body 315, both ends of the valve body 31 can be sealed, effectively preventing gas leakage from both ends of the valve body 31, thereby improving the overall sealing performance and adsorption stability of the adsorption device 100. By setting the conical groove 3121, a groove with a larger top and a smaller bottom is formed. When the sealing member 33 moves close to the connecting member 11 under negative pressure, the gap between the sealing member 33 and the groove wall of the conical groove 3121 can be gradually reduced until the sealing member 33 completely seals the conical groove 3121, ensuring that external gas will not enter the connecting member 11 through the uncovered connecting groove 23 and the corresponding conical groove 3121, thereby improving the adsorption stability of the workpiece 200.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
