[0002] The headphone cover is a component that covers the outside of the headphone unit. The headphone cover usually comes into direct contact with the ear and is usually made of soft material. Its main purpose is to cushion the pressure on the ear and reduce the feeling of pressure when wearing it for a long time, so as to isolate external noise.

[0003] The earcups are usually assembled with the earphones using a snap-on method.

[0054] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0055] like Figures 1 to 7 As shown, this embodiment proposes an automatic headphone cover assembly robot, including an assembly frame 1, on which an assembly robot body 2 and a mounting mechanism 3 are mounted. The mounting mechanism 3 is used to place and fix the headphones to be assembled. It also includes a lifting frame 4, a vision camera 5, an inflatable fixing component, and a flexible clamping component. The lifting frame 4 is fixedly installed at the working end of the assembly frame 1. The vision camera 5 is located at the bottom of the lifting frame 4. The inflatable fixing component is installed at the bottom of the lifting frame 4 and is used to contact the inner ring of the headphone cover to fix it. The inflatable fixing component includes a connecting frame 6, an annular airbag 8, and anti-slip protrusions. The connecting frame 6 is fixedly installed at the bottom of the hoisting frame 4. The connecting frame 6 is elliptical in shape. The vision camera 5 is fixedly installed at the bottom of the connecting frame 6. The outer side of the connecting frame 6 has an annular mounting groove 7. The annular airbag 8 is fixedly fitted on the mounting groove 7. The annular airbag 8 is adapted to the shape of the mounting groove 7. The inner circle of the annular airbag 8 is provided with an air inlet end and an air outlet end. The outer circle of the annular airbag 8 is provided with several strip-shaped anti-slip protrusions 9 at equal intervals. The several anti-slip protrusions 9 are all arranged parallel to the axis of the connecting frame 6. The inflation part is installed inside the hoisting frame 4 and is used to inflate and deflate the annular airbag 8.

[0056] Specifically, when assembling the earphone cover on the earphone, the earphone is first installed on the mounting mechanism 3 and the position where the earphone cover needs to be installed is ensured to be upward, then the earphone cover is sent to the side of the assembling robot body 2 through the conveying device of the external device, at this time the assembling robot body 2 is started to drive the lifting frame 4 to move, the position of the lifting frame 4 is detected through the visual camera 5 until the lifting frame 4 drives the connecting frame 6 and the flexible clamping assembly to move above the earphone cover, the position of the connecting frame 6 and the earphone cover is automatically aligned by the visual camera 5, then the lifting frame 4 is moved until the connecting frame 6 drives the annular air bag 8 to move to the inner circle of the earphone cover, at this time the inflation part is started to inflate the annular air bag 8 until the outer periphery of the annular air bag 8 contacts the earphone cover, so as to fix the shape of the earphone cover and adapt to the shape of the earphone cover more, avoiding that the earphone cover is obviously deformed when clamping the earphone cover, thereby affecting assembly, the vertical anti-skid protrusion 9 increases the friction with the earphone cover, thereby preventing the earphone cover from sliding in the circumferential direction along the mounting groove 7 in the inflation process, ensuring that the earphone cover is stably fixed, then the flexible clamping assembly is started to clamp the earphone cover, then the assembling robot body 2 is started again to move the earphone cover to the position where the earphone needs to be installed, under the action of the visual camera 5, the buckle at the bottom of the earphone cover is aligned with the corresponding recess of the earphone, and the earphone cover is installed on the earphone in a pressing or rotating manner, when the earphone cover needs to be loosened, the flexible clamping assembly is retracted and the air in the annular air bag 8 is discharged, and the earphone can be taken out after the installation is completed.

[0057] As shown in the above, Figure 3 , Figure 4 The inflation part includes a gas pump 10, an air inlet pipe 11, an air outlet pipe 12 and an air outlet control valve 13, the gas pump 10 is fixedly installed in the lifting frame 4, the air inlet pipe 11 is communicated between the output end of the gas pump 10 and the air inlet end of the annular air bag 8, the air outlet pipe 12 is communicated at the air outlet end of the annular air bag 8, and the air outlet control valve 13 is fixedly installed on the lifting frame 4 and communicated with the other end of the air outlet pipe 12.

[0058] It should be noted that the air inlet end and the air outlet end of the annular air bag 8 are both unidirectionally arranged, that is, when the air inlet pipe 11 stops discharging, the air entering the annular air bag 8 cannot be discharged from the air inlet end but only from the air outlet end.

[0059] Specifically, when the earphone cover is fixed by the annular air bag 8, the gas pump 10 is started to inflate the annular air bag 8 through the air inlet pipe 11 until the outer side of the annular air bag 8 contacts the earphone cover, and then the gas pump 10 is closed, so as to fix the earphone cover, when the earphone cover needs to be loosened, the air outlet control valve 13 is started to discharge the air in the annular air bag 8 from the air outlet pipe 12, so as to loosen the earphone cover.

[0060] AsFigures 4 to 6 As shown, the flexible clamping assembly is installed at the bottom of the hoisting frame 4 to clamp the headphone cover after its position is fixed. The flexible clamping assembly includes a first clamping slot 14, a second clamping slot 15, a first swing frame 16, a second swing frame 17, a flexible positioning part, and a flexible assembly part. Two first clamping slots 14 and two second clamping slots 15 are symmetrically opened at the bottom of the hoisting frame 4. The two second clamping slots 15 are staggered from the two first clamping slots 14. A first swing frame 16 is rotatably installed in each of the two first clamping slots 14. The two first swing frames 16 are symmetrically arranged. A second swing frame 17 is rotatably installed in each of the two second clamping slots 15. The two second swing frames 17 are symmetrically arranged. A flexible positioning part is installed at the bottom of each of the two first swing frames 16 for fixing the headphone cover. A flexible assembly part is installed at the bottom of each of the two second swing frames 17 for clamping the headphone cover during installation.

[0061] Specifically, when clamping the headphone cover, the two first swing brackets 16 are first driven to swing in the two first clamping slots 14 respectively, thereby fixing the headphone cover through the flexible positioning part and the annular airbag 8. Then, the two second swing brackets 17 are driven to swing in the two second clamping slots 15 respectively, thereby clamping the headphone cover through the flexible assembly part, ensuring that it is stable and does not move during use, thus improving the reliability of the headphone cover installation process. After assembly, when it is necessary to loosen the headphone cover, the two first swing brackets 16 and the two second swing brackets 17 are removed, so that the flexible positioning part and the flexible assembly part are disengaged from the headphone cover, thereby loosening the headphone cover.

[0062] The above, such as Figure 5 , Figure 6 As shown, the flexible positioning part includes a flexible positioning plate 18. The bottom of each of the two first swing frames 16 is detachably mounted with a flexible positioning plate 18 via a first top plate 19. The two flexible positioning plates 18 are arranged symmetrically. The inner sides of the two flexible positioning plates 18 are respectively adapted to the two ends of the long axis of the earphone cover to be clamped. Several mounting strips 20 are fixedly installed at equal distances on the side of the two flexible positioning plates 18 near the connecting frame 6. The end of the several mounting strips 20 near the hoisting frame 4 is set as a sawtooth shape.

[0063] Specifically, when the two first swing frames 16 swing in the two first clamping grooves 14 respectively, the two flexible positioning plates 18 are driven to swing by the two first top plates 19 respectively, and the serrated mounting strips 20 abut against the two ends of the long shaft of the earphone cover. The flexible positioning plates 18 are preferably made of rubber material, and when the flexible positioning plates 18 contact the earphone cover, the flexible positioning plates 18 are deformed, so that the serrated mounting strips 20 are more fitted to the outside of the earphone cover, and the serrated mounting strips 20 form stable support points to support the structure. The serrated design effectively prevents the earphone cover from sliding during installation, and ensures that the earphone cover does not displace during fixing. Meanwhile, the flexible positioning plates 18 made of rubber material can also buffer the impact force during installation, further improving the stability and safety of installation.

[0064] As shown in the above, Figure 5 , Figure 6 The flexible assembly part includes arc-shaped flexible assembly plates 21, and the two second swing frames 17 are detachably installed with the arc-shaped flexible assembly plates 21 at the bottoms through second top plates 22. The two arc-shaped flexible assembly plates 21 are symmetrically arranged, the inner sides of the two arc-shaped flexible assembly plates 21 are respectively adapted to the two ends of the short shaft of the earphone cover to be clamped, and a plurality of friction strips 23 are equidistantly arranged on the side of the two arc-shaped flexible assembly plates 21 close to the connecting frame 6, and the plurality of friction strips 23 are cross arranged.

[0065] Specifically, after the two ends of the long shaft of the earphone cover are fixed, the two second swing frames 17 swing in the two second clamping grooves 15 respectively, and the arc-shaped flexible assembly plates 21 are driven to swing by the second top plates 22, until the friction strips 23 are in close contact with the two ends of the short shaft of the earphone cover, and the position of the arc-shaped flexible assembly plate is fixed. The cross arrangement of the friction strips 23 increases the contact area, effectively prevents the earphone cover from sliding, and ensures stable clamping. The arc-shaped flexible assembly plates 21 are also preferably made of rubber material, and the arc-shaped design makes the arc-shaped flexible assembly plates 21 more fitted to the curved surface of the earphone cover, which increases the contact area with the earphone cover, improves the installation precision and stability.

[0066] During installation of the earphone cover, if the installation mode is a rotating mode, the arc-shaped flexible assembly plates 21 increase the friction force with the earphone cover through the cross-arranged friction strips 23, which can effectively clamp the earphone cover for rotation to install. If the installation mode is a combination of a rubber ring and a groove, the cross-arranged friction strips 23 can still provide stable support during the pressing process, ensuring stable installation of the earphone cover.

[0067] As shown in the above, Figure 7As shown, the device further comprises a swing assembly for driving the first swing frame 16 and the second swing frame 17 to swing, which comprises a driving member 24, a driving frame 25, a sliding groove 26 and a sliding column 27. Four driving members 24 are symmetrically and fixedly installed inside the lifting frame 4. The two first clamping grooves 14 and the two second clamping grooves 15 are provided with the driving members 24 near one side of the connecting frame 6. The driving frame 25 is sleeved on the upper part of the two first swing frames 16 and the two second swing frames 17. The driving frame 25 is fixedly connected with the output end of the driving member 24. The driving frame 25 is slidingly installed inside the lifting frame 4 along the stroke direction of the driving member 24. The sliding grooves 26 are formed in the two sides of the two first swing frames 16 and the two second swing frames 17. The two sliding columns 27 are symmetrically installed inside each driving frame 25 and slidingly fit with the sliding grooves 26.

[0068] Specifically, when the first swing frame 16 or the second swing frame 17 needs to be driven to swing, the driving member 24 is started to drive the driving frame 25 to move. The driving frame 25 drives the sliding column 27 to move. At this time, the sliding column 27 slides in the sliding groove 26 to drive the swing frame to swing, thereby clamping the earphone cover.

[0069] As shown above, Figure 7 As shown, the bottom of the two first swing frames 16 and the two second swing frames 17 is provided with an assembly groove 28. A plurality of anti-skid protrusions 29 are equidistantly arranged inside each assembly groove 28. The anti-skid protrusions 29 are arranged perpendicularly to the sliding direction of the assembly groove 28.

[0070] Specifically, the bottom of the first swing frame 16 and the second swing frame 17 is provided with the assembly groove 28. During the installation of the flexible positioning plate 18, the first top plate 19 or the top plate is inserted into the assembly groove 28 at the bottom of the first swing frame 16. The anti-skid protrusions 29 are in contact with the bottom of the first top plate 19 to provide additional friction to prevent sliding. Then, the above steps are repeated to install the arc-shaped flexible assembly plate 21. The anti-skid protrusions 29 are in close contact with the bottom of the top plate to further enhance the stability during use and facilitate disassembly and assembly.

[0071] The working principle or use process of the present application is as follows:

[0072] When the earphone cover is assembled on the earphone, the earphone is first installed on the mounting mechanism 3, and the position where the earphone cover needs to be installed is ensured to be upward, then the earphone cover is sent to the side of the assembly robot body 2 through the conveying device of the external device, at this time the assembly robot body 2 is started to drive the lifting frame 4 to move, the position of the lifting frame 4 is detected by the visual camera 5 until the lifting frame 4 drives the connecting frame 6 to move above the earphone cover, then the position of the connecting frame 6 and the earphone cover is automatically aligned by the visual camera 5, and then the lifting frame 4 is moved until the connecting frame 6 drives the annular air bag 8 to move to the inner circle of the earphone cover, at this time the air pump 10 is started, the air pump 10 fills air into the annular air bag 8 through the air inlet pipe 11 until the outer side of the annular air bag 8 contacts the earphone cover, that is, the air pump 10 can be closed, so as to fix the earphone cover and avoid that the earphone cover is deformed obviously when clamping the earphone cover, thereby affecting assembly, the vertical anti-skid protrusions 9 increase the friction with the earphone cover, thereby preventing the earphone cover from sliding in the circumferential direction along the mounting groove 7 in the air filling process, and ensuring that the earphone cover is stably fixed in position.

[0073] Then the earphone cover is clamped, the driving part 24 is started, the driving frame 25 is pushed to move, the driving frame 25 drives the slide column 27 to move, at this time the slide column 27 slides in the sliding groove 26 to drive the first swing frame 16 and the second swing frame 17 to swing, the two first swing frames 16 swing in the two first clamping grooves 14 respectively, that is, the two flexible positioning plates 18 are driven to swing by the two first top plates 19 respectively, at this time the serrated mounting strips 20 abut against both ends of the long shaft of the earphone cover, the flexible positioning plate 18 is preferably made of rubber material, when contacting the earphone cover, the flexible positioning plate 18 deforms, so that the serrated mounting strips 20 are more fitted to the outer side of the earphone cover, so as to form a stable support point to support the structure, the serrated design effectively prevents the earphone cover from sliding in the installation process, ensures that the earphone cover does not displace in the fixing process, and the flexible positioning plate 18 made of rubber material can also buffer the impact force in the installation process, thereby further improving the stability and safety of the installation.

[0074] After the two ends of the long shaft of the earphone cover are fixed, the two second swing frames 17 swing in the two second clamping grooves 15 respectively, the arc-shaped flexible assembly plate 21 is driven to swing by the second top plate 22, until the friction strips 23 are in close contact with both ends of the short shaft of the earphone cover, that is, the position of the arc-shaped flexible plate is fixed, the friction strips 23 are arranged in cross, thereby increasing the contact area, effectively preventing the earphone cover from sliding, ensuring clamping stability, and the arc-shaped flexible assembly plate 21 is also preferably made of rubber material, and the arc-shaped design makes the arc-shaped flexible assembly plate 21 more fitted to the curved surface of the earphone cover, which increases the contact area with the earphone cover, improves the installation precision and stability.

[0075] Then through the setting of assembling the robot body 2, the earphone cover is aligned with the earphone, the earphone assembly is installed to the designated position of the earphone, the assembly of the earphone cover is completed, and then the earphone cover is loosened, at this time the exhaust control valve 13 is started, so that the air in the annular air bag 8 is exhausted from the exhaust pipe 12, and at the same time the driving member 24 is retracted, so that the flexible positioning plate 18 and the arc-shaped flexible assembly plate 21 are separated from the contact of the earphone cover, thereby loosening the earphone cover, and the earphone can be taken out after the assembly is completed.

[0076] The above only is the preferred embodiment of the present application, and does not limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
