Description

[Technical field]

[0001] The invention belongs to the technical field of earphone ear shell films, and in particular relates to an earphone ear shell automatic protective film wrapping device. [Background technology]

[0002] As people pursue a better quality of life, more and more high-gloss ear shells are appearing on the market to meet consumers' demand for a perfect earphone appearance. However, high-gloss ear shells are easily scratched during subsequent packaging and assembly, resulting in poor appearance. Therefore, they need to be wrapped with a protective film to avoid defective products. The traditional method of wrapping the ear shell with a protective film is to use a customized die-cut protective film and wrap it manually. When wrapping the protective film manually, hold the ear shell with one hand and hold a roll of protective film with the other hand to rotate the protective film around the edge of the ear shell for wrapping. The protective film needs to be tightened with a large force while wrapping it. If the protective film is not tightened enough, it is easy for the protective film to loosen after being placed for a period of time. Manually wrapping the protective film is inefficient and has large errors. It cannot meet production requirements, and it is labor-intensive and costly. [Summary of the invention]

[0050] Specific embodiments, such as Figure 1-7The device for automatically wrapping a protective film around an earphone ear shell shown in the figure comprises a workbench 1, on which a protective cover 2 is provided, a jig seat 3 for placing an earphone ear shell 100, a rotation drive assembly 4 for driving the jig seat 3 to rotate, an ear shell pressing assembly 5 for pressing the earphone ear shell on the jig seat 3 and rotating synchronously with the rotation of the jig seat 3, a protective film feeding assembly 6 for providing a protective film 200 and shifting the protective film 200 to the earphone ear shell corresponding to the jig seat 3, a protective film pressing assembly 7 for pressing the protective film onto the earphone ear shell, and a protective film cutting assembly 8 for cutting the protective film. When in use, the ear shell of the earphone is placed on the jig seat, the protective film is shifted to the position corresponding to the ear shell of the earphone through the protective film feeding assembly, the ear shell pressing assembly cooperates with the jig seat to press and fix the ear shell of the earphone, and then the protective film pressing assembly is used to press the protective film on the ear shell of the earphone, and the jig seat and the ear shell pressing assembly are driven by the rotary drive assembly to rotate together to drive the ear shell of the earphone to rotate, so as to wrap the protective film, and the rotation stops after the rotation reaches the set number of winding circles, and the protective film is cut off by the protective film cutting assembly, so as to realize the automatic wrapping of the ear shell of the earphone with the protective film, which is highly efficient and reduces the labor intensity and production cost. Furthermore, a protective cover 2 is provided to play a protective and dustproof role.

[0051] Specifically, the ear shell pressing assembly 5 includes an ear shell pressing mounting frame 51, a pressing head mounting plate 52, a pressing head 53 and a pressing head driving member 54. The ear shell pressing mounting frame 51 is arranged on the workbench 1; the pressing head 53 is rotatably arranged on the pressing head mounting plate 52; the pressing head driving member 54 is arranged on the workbench 1, and is used to drive the pressing head mounting plate 52 to move up and down. The pressing head driving member 54 adopts a telescopic cylinder. When in use, the telescopic end of the telescopic cylinder extends to drive the pressing head mounting plate 52 and the pressing head 53 to descend and press the ear shell of the earphone on the fixture seat 3. At the same time, the pressing head 53 can rotate with the rotation of the ear shell of the earphone, ensuring that the ear shell of the earphone can also remain fixed on the fixture seat 3 during rotation.

[0052] More specifically, the pressing head mounting plate 52 includes an upper mounting plate 521, a guide post 522, a lower mounting plate 523, and a first elastic element 524. The upper mounting plate 521 is connected to the pressing head driving member 54; the guide post 522 is movably disposed on the upper mounting plate 521; the lower mounting plate 523 is connected to the guide post 522; the first elastic element 524 is sleeved on the guide post 522 and is located between the upper mounting plate 521 and the lower mounting plate 523. The elastic force of the first elastic element 524 allows the pressing head to press against the ear shell of the earphone, which plays a buffering role and avoids damaging the ear shell of the earphone.

[0053] In addition, the protective film feeding assembly 6 includes a protective film feeding cylinder 61, a protective film clamping member 62, and a lifting and lateral movement mechanism 63. The protective film feeding cylinder 61 is arranged on the workbench 1, and is used to provide a protective film; the protective film clamping member 62 is used to clamp the protective film provided by the protective film feeding cylinder 61; the lifting and lateral movement mechanism 63 is arranged on the workbench 1, and is used to drive the protective film clamping member 62 to lift and lateral movement, so as to shift the protective film clamped by the protective film clamping member 62 to a position corresponding to the ear shell of the earphone on the fixture seat 3. More specifically, the protective film feeding assembly 6 also includes a guide plate 64 and a tensioning wheel 65 arranged on the workbench 1. When in use, the protective film is clamped by the protective film clamping member 62, and then the lifting and transverse movement mechanism 63 drives one end of the protective film clamped by the protective film clamping member 62 to move transversely to correspond to the ear shell of the earphone on the fixture seat 3. At the same time, the protective film is guided by the guide plate 64 and the tensioning wheel 65 to tension the protective film to ensure that the protective film is transported taut.

[0054] Furthermore, the lifting and transverse movement mechanism 63 includes a first movable guide rail 631 arranged along the X-axis direction, a first movable slider 632 slidingly arranged on the first movable guide rail 631, a first movable drive motor 633 for driving the first movable slider 632 to slide, and a first lifting cylinder 634 arranged on the first movable slider 632, and the protective film clamping member 62 is arranged at the output end of the first lifting cylinder 634.

[0055] Specifically, the protective film clamping assembly 7 includes a clamping rail 71, a clamping slider 72, a clamping wheel 73, a clamping driver 74, and a clamping spring 75.

Before the protective film feeding assembly 6 shifts the protective film, the clamping drive component 74 first drives the clamping wheel 73 to move away from the protective film. When the protective film feeding assembly 6 moves the protective film horizontally to a position corresponding to the earphone ear shell on the fixture seat 3, the clamping drive component 74 drives the clamping wheel 73 to retract, and the elastic force of the clamping spring 75 pulls the clamping wheel 73 toward the protective film and presses the protection on the highlight surface of the earphone ear shell. At the same time, when the earphone ear shell rotates, the clamping wheel 73 always keeps the protective film pressed against the earphone ear shell due to the tension of the clamping spring 75.

[0056] Furthermore, the rotary drive assembly 4 includes a rotary mounting plate 41, a driven shaft 42, a driven gear 43, a rotary drive motor 44, a driving gear 45 and a transmission belt 46.

The fixture seat 3 is driven to rotate by the rotary drive motor 44. Specifically, the fixture seat 3 is rotated clockwise for about 10 mm to allow the end face of the protective film suspended outside the ear shell of the earphone to stick to the ear shell of the earphone and then rotated counterclockwise. As the ear shell of the earphone rotates, the protective film is wrapped around the ear shell. The number of turns of the protective film can be set by modifying the parameters of the rotary drive motor 44 on the control touch screen.

[0057] Furthermore, the protective film cutting assembly 8 includes a cutting mounting frame 81, a cutting telescopic cylinder 82 disposed on the cutting mounting frame 81, and a cutting knife 83 disposed at the telescopic end of the cutting telescopic cylinder 82. The telescopic direction of the cutting telescopic cylinder 82 is perpendicular to the feeding direction of the protective film. The cutting telescopic cylinder 82 drives the cutting knife 83 to move in a direction perpendicular to the conveying direction of the protective film to cut the protective film.

[0058] Specifically, the workbench 1 is further provided with a mobile driving assembly 9, which is used to drive the fixture seat 3 to move in a direction close to or away from the ear shell pressing assembly 5, and the mobile driving assembly 9 includes a second mobile guide rail 91 arranged along the Y-axis direction, a second mobile slider 92 slidably arranged on the second mobile guide rail 91, and a second mobile driving motor 93 for driving the second mobile slider 92 to slide, and the fixture seat 3 is arranged on the second mobile slider 92.
