[0043] Among them, such as Figure 1-14 As shown, the tail rotating assembly 3 includes a first mounting bracket 3-1, a rotating mounting cylinder 3-2, and a first gear 3-3. The first mounting bracket 3-1 is mounted on the mounting plate 1-1, the rotating mounting cylinder 3-2 is mounted on the first mounting bracket 3-1, the rotating mounting cylinder 3-2 is used to mount the tail of the earphone, and the first gear 3-3 is mounted on the rotating mounting cylinder 3-2. The third transmission device 8 is connected to the first gear 3-3 through the gear set 10.

[0044] The first gear 3-3 drives the earphone to rotate by rotating the mounting cylinder 3-2.

[0045] Among them, such as Figure 1-14 As shown, the head rotation assembly 4 includes a fixed track 4-1, a movable frame 4-2, a rotating shaft 4-3, and a contoured head 4-4.

The connecting plate 5-4 drives the contour positioning workpiece 2-2 to move through the first transmission device 6.

[0048] The linear motor 5-3 drives the connecting plate 5-4 to slide on the linear track 5-2.

[0049] Among them, such as Figure 1-14 As shown, the first transmission device 6 includes a connecting rod 6-1, a push plate 6-2, a moving groove 6-3, and a first spring 6-4. The connecting rod 6-1 is mounted on the connecting plate 5-4, the push plate 6-2 is mounted on the connecting rod 6-1, and the moving groove 6-3 is mounted on the contour positioning workpiece 2-2. The connecting rod 6-1 slides inside the moving groove 6-3. The first spring 6-4 is provided between the connecting rod 6-1 and the moving groove 6-3. The push plate 6-2 presses to release the restriction of the limiting device 9 on the third transmission device 8.

[0050] The movable connecting rod 6-1 moves the movable groove 6-3 by squeezing the first spring 6-4. The movable groove 6-3 moves the contour positioning workpiece 2-2. When the contour positioning workpiece 2-2 cannot move, the first spring 6-4 will be compressed, allowing the connecting rod 6-1 to move further. When the connecting rod 6-1 squeezes the limiting device 9 through the push plate 6-2, the limiting device 9 will release the restriction on the third transmission device 8.

[0051] Among them, such as Figure 1-14 As shown, the second transmission device 7 includes a first rack 7-1, a mounting base 7-2, a transmission connecting shaft 7-3, a second gear 7-4, a third gear 7-5, and a second rack 7-6. The first rack 7-1 is mounted on the contour positioning workpiece 2-2. The mounting base 7-2 is mounted on the mounting plate 1-1. The transmission connecting shaft 7-3 is mounted on the mounting base 7-2. The transmission connecting shaft 7-3 is equipped with the second gear 7-4 and the third gear 7-5. The second gear 7-4 meshes with the first rack 7-1, and the third gear 7-5 meshes with the second rack 7-6. The second rack 7-6 is mounted on the movable frame 4-2.

[0052] The moving contour positioning workpiece 2-2 drives the first rack 7-1 to move. The first rack 7-1 drives the third gear 7-5 to rotate through the second gear 7-4 and the transmission connecting shaft 7-3. The rotating gear moves through the second rack 7-6. The moving second rack 7-6 drives the moving frame 4-2 to move.

[0053] Among them, such as Figure 1-14 As shown, the third transmission device 8 includes a push bar 8-1, a movable sleeve 8-2, a sliding plate 8-3, a third spring 8-4, a limiting sleeve 8-5, and a push tooth 8-6.

[0054] The moving frame 4-2 drives the push bar 8-1 to move. However, due to the movement of the limiting device 9, the moving sleeve 8-2 cannot move. Therefore, the moving sleeve 8-2 will move relative to the push bar 8-1 and compress the third spring 8-4. When the moving sleeve 8-2 is released from the restriction, the compressed third spring 8-4 will push the moving sleeve 8-2 outward. The moving sleeve 8-2 drives the push tooth 8-6 to move together.

[0055] Among them, such as Figure 1-14 As shown, the limiting device 9 includes a limiting block 9-1, a limiting groove 9-2, an inclined surface 9-3, a fixing bolt 9-4, a sliding plate 9-5, a lifting plate 9-6, and a fourth spring 9-7.

The fixing bolt 9-4 is disposed on the mounting plate 1-1, and the sliding plate 9-5 slides on the fixing bolt 9-4. A fourth spring 9-7 is provided between the sliding plate 9-5 and the fixing bolt 9-4. The lifting plate 9-6 is disposed on the sliding plate 9-5. The sliding plate 9-5 enters the limiting groove 9-2 to restrict the movement of the movable sleeve 8-2, and the pushing plate 6-2 pushes the lifting plate 9-6 to release the restriction.

[0056] When the sliding plate 9-5 is inside the limiting groove 9-2, the movable sleeve 8-2 is limited and cannot move. When the pushing plate 6-2 pushes the lifting plate 9-6 to push the sliding plate 9-5 out of the limiting groove 9-2, the movable frame 4-2 drives the contour head 4-4 to wrap around the head of the earphone. Then, the compressed third spring 8-4 pushes the movable sleeve 8-2 to move. The movable sleeve 8-2 drives the gear set 10 to rotate through the pushing tooth 8-6. The rotating gear set 10 drives the rotating mounting cylinder 3-2 to rotate, thereby driving the earphone to rotate and complete the film application. The inclined surface 9-3 allows the sliding plate 9-5 to easily enter the limiting groove 9-2 after the movable sleeve 8-2 is reset.

[0057] It is understood that the present invention has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of the present invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
