Specific embodiments

[0054] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 making creative efforts fall within the scope of protection of the present invention.

[0055] As Figures 1 to 7 shown, this embodiment proposes an automatic assembly robot for earphone covers, including an assembly frame 1, an assembly robot body 2 and an installation mechanism 3 are installed on the assembly frame 1. The installation mechanism 3 is used to place and fix the earphones of the earphone covers to be assembled. It also includes a hoisting frame 4, a vision camera 5, an inflatable fixing component and a flexible clamping component. The hoisting frame 4 is fixedly installed at the working end of the assembly frame 1. The vision camera 5 is arranged at the bottom of the hoisting frame 4. The inflatable fixing component is installed at the bottom of the hoisting frame 4 and is used to contact the inner ring of the earphone cover to fix the earphone cover. The inflatable fixing component includes a connecting frame 6, an annular airbag 8, anti-slip protrusions 9 and an inflating part. The connecting frame 6 is fixedly installed at the bottom of the hoisting frame 4. The connecting frame 6 is arranged in an elliptical shape. The vision camera 5 is fixedly installed at the bottom of the connecting frame 6. An annular installation groove 7 is opened on the outer side of the connecting frame 6. The annular airbag 8 is fixedly sleeved on the installation groove 7. The annular airbag 8 is adapted to the shape of the installation groove 7. The inner ring of the annular airbag 8 is provided with an air inlet end and an air outlet end. A plurality of strip-shaped anti-slip protrusions 9 are equidistantly arranged on the outer circular part of the annular airbag 8. A plurality of anti-slip protrusions 9 are all arranged parallel to the axis position of the connecting frame 6. The inflating 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, first install the earphone on the installation mechanism 3 and ensure that the position where the earphone cover needs to be installed is upward. Then, through an external conveying device, send the earphone cover to the side of the assembly robot body 2. At this time, start the assembly robot body 2 to drive the hoisting rack 4 to move. Detect the position of the hoisting rack 4 through the vision camera 5 until the hoisting rack 4 drives the connecting frame 6 and the flexible clamping assembly to move above the earphone cover. Automatically align the position of the connecting frame 6 and the earphone cover by the vision camera 5. Then move the hoisting rack 4 until the connecting frame 6 drives the annular airbag 8 to move into the inner circle of the earphone cover. At this time, start the inflation part to inflate the annular airbag 8 until the outer periphery of the annular airbag 8 contacts the earphone cover, so as to fix the shape of the earphone cover and better adapt to the shape of the earphone cover, avoiding obvious deformation of the earphone cover when clamping it, thus affecting the assembly. Increase the friction with the earphone cover through the vertically arranged anti-slip protrusions 9, so as to prevent the earphone cover from sliding circumferentially along the installation groove 7 during the inflation process and ensure the stable positioning of the earphone cover. Then start the flexible clamping assembly to clamp the earphone cover. Then start the assembly robot body 2 again to move the earphone cover to the position where the earphone needs to install the earphone cover. Under the action of the vision camera 5, align the buckle at the bottom of the earphone cover with the groove at the corresponding position of the earphone, and install the earphone cover on the earphone by pressing or rotating. When it is necessary to loosen the earphone cover, retract the flexible clamping assembly and discharge the air in the annular airbag 8. After the installation is completed, the earphone can be taken out.

[0057] As described above, such as Figure 3 , Figure 4 shown, the inflation part includes an air pump 10, an air inlet pipe 11, an exhaust pipe 12 and an exhaust control valve 13. The air pump 10 is fixedly installed inside the hoisting rack 4. The air inlet pipe 11 is connected between the output end of the air pump 10 and the air inlet end of the annular airbag 8. The exhaust pipe 12 is connected to the air release end of the annular airbag 8. The exhaust control valve 13 is fixedly installed on the hoisting rack 4 and is connected to the other end of the exhaust pipe 12.

[0058] It should be added that both the air inlet end and the air release end of the annular airbag 8 are set unidirectionally, that is, when inflating, after the air inlet pipe 11 stops exhausting, the air entering the inside of the annular airbag 8 cannot be discharged from the air inlet end and can only be discharged from the air release end.

[0059] Specifically, when fixing the earphone cover through the annular airbag 8, start the air pump 10. The air pump 10 inflates the annular airbag 8 through the air inlet pipe 11 until the outer side of the annular airbag 8 contacts the earphone cover, then the air pump 10 can be closed to fix the earphone cover. When it is necessary to loosen the earphone cover, start the exhaust control valve 13 to make the air in the annular airbag 8 be discharged from the exhaust pipe 12, thus loosening the earphone cover.

[0060] Such asFigures 4 to 6 As shown in the figure, the flexible clamping assembly is installed at the bottom of the hoisting frame 4 and is used to clamp the earphone cover after the position of the earphone cover is fixed. The flexible clamping assembly includes a first clamping groove 14, a second clamping groove 15, a first swing frame 16, a second swing frame 17, a flexible positioning part and a flexible assembly part. Two first clamping grooves 14 are symmetrically formed at the bottom of the hoisting frame 4, and two second clamping grooves 15 are symmetrically formed at the bottom of the hoisting frame 4. The two second clamping grooves 15 are arranged staggeredly with the two first clamping grooves 14. A first swing frame 16 is rotatably installed in each of the two first clamping grooves 14, and the two first swing frames 16 are symmetrically arranged. A second swing frame 17 is rotatably installed in each of the two second clamping grooves 15, and the two second swing frames 17 are symmetrically arranged. Flexible positioning parts are installed at the bottoms of the two first swing frames 16 and are used to fix the earphone cover, and flexible assembly parts are installed at the bottoms of the two second swing frames 17 and are used to clamp the earphone cover during installation.

[0061] Specifically, when clamping the earphone cover, it is necessary to first drive the two first swing frames 16 to swing in the two first clamping grooves 14 respectively, so as to fix the earphone cover through the flexible positioning part and cooperate with the annular airbag 8. Then, drive the two second swing frames 17 to swing in the two second clamping grooves 15 respectively, so as to clamp the earphone cover through the flexible assembly part, ensuring its stability during use and improving the reliability during the installation process of the earphone cover. After the assembly is completed, when the earphone cover needs to be released, move the two first swing frames 16 and the two second swing frames 17 away, so that the flexible positioning part and the flexible assembly part are separated from the contact with the earphone cover, thereby releasing the earphone cover.

[0062] As described above, as Figure 5 、 Figure 6 shown in the figure, the flexible positioning part includes a flexible positioning plate 18. Flexible positioning plates 18 are detachably installed at the bottoms of the two first swing frames 16 through first top plates 19. The two flexible positioning plates 18 are symmetrically arranged. 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. A plurality of mounting strips 20 are evenly and fixedly installed on one side of the two flexible positioning plates 18 close to the connecting frame 6. One ends of the plurality of mounting strips 20 close to the hoisting frame 4 are all serrated.

[0063] Specifically, when the two first swing frames 16 swing in the two first clamping grooves 14 respectively, the two flexible positioning plates 18 can be driven to swing by the two first top plates 19 respectively. At this time, the serrated mounting strips 20 are abutted against both ends of the long axis of the earphone cover. The flexible positioning plates 18 are preferably made of rubber material. When contacting the earphone cover, the flexible positioning plates 18 are deformed, so that the serrated mounting strips 20 fit more closely to the outer side of the earphone cover, forming stable support points to support the structure. The serrated design effectively prevents the earphone cover from sliding during installation, ensuring that the earphone cover will not be displaced during fixation. At the same time, 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 described above, Figure 5 , Figure 6 As shown in, the flexible assembly part includes an arc-shaped flexible assembly plate 21. The bottoms of the two second swing frames 17 are detachably installed with arc-shaped flexible assembly plates 21 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 both ends of the short axis of the earphone cover to be clamped. A plurality of friction strips 23 are equidistantly arranged on one side of the two arc-shaped flexible assembly plates 21 close to the connecting frame 6, and the plurality of friction strips 23 are arranged in a cross pattern.

[0065] Specifically, after both ends of the long axis 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 both ends of the short axis of the earphone cover, then the position of the arc-shaped flexible plate can be fixed. The friction strips 23 are arranged in a cross pattern, so as to increase the contact area, effectively prevent the earphone cover from sliding, ensure firm clamping, and the arc-shaped flexible assembly plates 21 are also preferably made of rubber material. At the same time, the arc-shaped design makes the arc-shaped flexible assembly plates 21 fit more closely to the curved surface of the earphone cover, which increases the contact area with the earphone cover and improves the installation accuracy and stability.

[0066] When installing the earphone cover, if the installation method is a rotation method, the arc-shaped flexible assembly plate 21 increases the friction force with the earphone cover through the cross-arranged friction strips 23, and can effectively clamp the earphone cover for rotation to install. If the installation method is the cooperation of a rubber ring and a groove for installation, then during the pressing process, the cross-arranged friction strips 23 can still provide stable support to ensure the stable installation of the earphone cover.

[0067] As described above, Figure 7As shown in the figure, it further includes a swing assembly for driving the first swing frame 16 and the second swing frame 17 to swing, including 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 hoisting machine frame 4. Driving members 24 are provided on one side of the two first clamping grooves 14 and the two second clamping grooves 15 close to the connecting frame 6. Driving frames 25 are sleeved on the upper parts of the two first swing frames 16 and the two second swing frames 17. The driving frame 25 is fixedly connected to the output end of the driving member 24. The driving frame 25 is slidably installed inside the hoisting machine frame 4 along the stroke direction of the driving member 24. Sliding grooves 26 are formed on both sides of the two first swing frames 16 and both sides of the two second swing frames 17. Two sliding columns 27 are symmetrically installed inside each driving frame 25. The sliding columns 27 are slidably matched with the sliding grooves 26.

[0068] Specifically, when it is necessary to drive the first swing frame 16 or the second swing frame 17 to swing, start the driving member 24 to push 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, so as to clamp the earphone cover.

[0069] As described above, Figure 7 As shown in the figure, assembly grooves 28 are provided at the bottoms of the two first swing frames 16 and the two second swing frames 17. A number of anti-slip ridges 29 are equidistantly arranged inside each assembly groove 28. The anti-slip ridges 29 are arranged perpendicular to the sliding direction of the groove of the assembly groove 28.

[0070] Specifically, assembly grooves 28 are provided at the bottoms of the first swing frame 16 and the second swing frame 17. During the installation of the flexible positioning plate 18, insert the first top plate 19 or the top plate into the assembly groove 28 at the bottom of the first swing frame 16. Contact with the bottom of the first top plate 19 through the anti-slip ridges 29 to provide additional friction to prevent sliding. Then repeat the above steps to install the arc-shaped flexible assembly plate 21. Through the close contact between the anti-slip ridges 29 and the bottom of the top plate, the stability during use is further enhanced, and it is convenient for disassembly and assembly.

[0071] The working principle or usage process of this application is:

[0072] When assembling the earphone cover on the earphone, first install the earphone on the installation mechanism 3 and ensure that the position where the earphone cover needs to be installed faces upward. Then, through an external conveying device, send the earphone cover to the side of the assembly robot body 2. At this time, start the assembly robot body 2 to drive the lifting rack 4 to move. Detect the position of the lifting rack 4 through the vision camera 5 until the lifting rack 4 drives the connecting frame 6 to move above the earphone cover. Automatically align the position of the connecting frame 6 and the earphone cover by the vision camera 5. Then move the lifting rack 4 until the connecting frame 6 drives the annular airbag 8 to move into the inner circle of the earphone cover. At this time, start the air pump 10. The air pump 10 inflates the annular airbag 8 through the air inlet pipe 11 until the outer side of the annular airbag 8 contacts the earphone cover, then the air pump 10 can be closed, thereby fixing the earphone cover, avoiding obvious deformation of the earphone cover when clamping the earphone cover, which affects the assembly. Increase the friction with the earphone cover through the vertically arranged anti-slip protrusions 9, thereby preventing the earphone cover from sliding circumferentially along the installation groove 7 during the inflation process, ensuring the stable positioning of the earphone cover.

[0073] Then clamp the earphone cover. Start the driving member 24 to push 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, driving 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, and then the two flexible positioning plates 18 can be driven to swing by the two first top plates 19 respectively. At this time, the serrated installation strip 20 abuts against both ends of the long axis 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, making the serrated installation strip 20 more conform to the outer side of the earphone cover, forming stable support points to support the structure. The serrated design effectively prevents the earphone cover from sliding during the installation process, ensuring that the earphone cover does not displace during the fixing process. At the same time, the rubber material flexible positioning plate 18 can also buffer the impact force during installation, further improving the stability and safety of the installation.

[0074] After fixing both ends of the long axis of the earphone cover, the two second swing frames 17 swing in the two second clamping grooves 15 respectively, driving the arc-shaped flexible assembly plate 21 to swing through the second top plate 22 until the friction strips 23 are in close contact with both ends of the short axis of the earphone cover, then the position of the arc-shaped flexible plate can be fixed. The friction strips 23 are arranged in a cross pattern, thereby increasing the contact area, effectively preventing the earphone cover from sliding, ensuring firm clamping. And the arc-shaped flexible assembly plate 21 is also preferably made of rubber material. At the same time, the arc-shaped design makes the arc-shaped flexible assembly plate 21 more conform to the curved surface of the earphone cover, which increases the contact area with the earphone cover, improving the installation accuracy and stability.

[0075] Then, through the setting of the assembled robot body 2, align the earphone cover with the earphone, install the earphone component at the designated position of the earphone to complete the assembly of the earphone cover. Then loosen the earphone cover. At this time, start the exhaust control valve 13 so that the air in the annular airbag 8 is discharged from the exhaust pipe 12. At the same time, retract the driving member 24 to separate the flexible positioning plate 18 and the arc-shaped flexible assembly plate 21 from contacting the earphone cover, thereby loosening the earphone cover. After the assembly is completed, the earphone can be taken out.

[0076] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
