The width of the positioning element 20 is equal to or greater than the distance between two adjacent second winding surfaces 11, and specifically, is slightly greater than the distance between two adjacent second winding surfaces 11, so as to implement the winding operation more effectively.

Specifically, in the present embodiment, the second winding surface 11 is an inclined surface, and specifically, the edge of the upper end surface 12 of the winding disk 10 is inclined obliquely downward toward the front end surface 13 and the rear end surface 14 thereof, respectively. Correspondingly, the clamping surface 31 is also an inclined surface, so that the two inclined surfaces can be matched to clamp the lug wire 200 wound between the two, the structure is simple, and the clamping is convenient.

The wire-wound plate 10 in this embodiment not only can be used to place the positioning member 20 and the clamping member 30 and drive them to rotate, but also can be used to simplify the structure and optimize the manufacturing process, thereby reducing the manufacturing cost.

Specifically, a rotating shaft 15 is provided at the center of the receiving plate 10, and the rotating shaft 15 is used for connecting with a rotating driver (not shown in the figure), so that the receiving plate 10 can be driven by the rotating driver to rotate for 180 ° each time.

Of course, the lower end of the arc-shaped portion 22 may also extend outwardly to form a rib at the lower edge of the first winding surface 21, so as to further prevent the ear wire 200 from slipping off the wound first winding surface 21 during the winding process.

Referring to fig. 2 and 3, in order to facilitate the installation of the clamping members 30, an installation groove 10c is respectively formed at the edge of each second winding surface 11 corresponding to the front and rear opposite ends of the upper end surface 12 of the winding plate 10, and four clamping members 30 are rotatably installed in the corresponding installation grooves 10 c. Specifically, the positioning slot 10c is an L-shaped slot, and can extend from the upper end surface 12 of the reel 10 to the lower end surface 16 of the reel 10.

With reference to fig. 4 and 5, the ear wire winding positioning structure 100 of the present invention further includes an anti-slip member 40, the anti-slip member 40 and the second winding surface 11 are disposed in a one-to-one correspondence, and can be protruded on the upper end of the second winding surface 11 corresponding to the second winding surface for preventing the ear wire 200 from slipping off from the second winding surface 11. Specifically, the anti-slip member 40 is disposed on the upper end surface 12 of the bobbin disk 10 and can be suspended from the upper end of the second bobbin surface 11 to form a rib. The anti-slip member 40 is block-shaped, and the abutting surface 41 of the block-shaped anti-slip member 40 abutting against the winding disc 10 is a plane, a limit included angle is formed between the plane abutting surface 41 and the second winding surface 11 of the inclined surface, and the ear wire 200 wound on the second winding surface 11 slides in the range defined by the limit included angle, so that the ear wire 200 is effectively prevented from slipping off the wound second winding surface 11.

It should be noted that, as shown in fig. 5, when the reel 10 rotates 180 °, an ear wire segment 201 with a length and a shape is formed by winding between a positioning member 20 and two adjacent clamping members 30, and at this time, the ear wire segment 201 only needs to be cut off from the whole ear wire 200, and fig. 5 is a cut-off diagram, so that the uninterrupted operation of winding and positioning the ear wire 200 can be realized with the continuous rotation of the reel 10.

Referring to fig. 6 to 10, in the second embodiment of the ear wire wrapping positioning structure 100 of the present invention, the main difference from the first embodiment is that: the second winding surface 11 is a vertical surface, and is specifically disposed at the lower end of the front end surface 13 and the rear end surface 14 of the winding disc 10, and the upper end of the front end surface 13 and the rear end surface 14 of the winding disc 10 is an inclined surface or a vertical surface connected to the second winding surface 11. In contrast, the holding surface 31 is a vertical surface so that the ear line 200 wound between the two vertical surfaces can be firmly clamped. When the ear wire 200 is in a round strip shape, the holding surface 31 may be an arc surface whose radian corresponds to the shape of the outer contour of the ear wire 200, so that the holding stability can be enhanced. Correspondingly, the anti-slip member 40 is block-shaped, and the contact surface 41 of the block-shaped anti-slip member 40 with the reel 10 is substantially L-shaped. In this embodiment, one end of the anti-slip element 40 suspended at the upper end of the second winding surface 11 completely protrudes from the second winding surface 11, so as to form a boss at the upper end of the second winding surface 11, and the suspension surface 42 of the boss may be a plane, an inclined surface or an arc surface.

Referring to fig. 11 to 13, in the third embodiment of the ear wire wrapping positioning structure 100 of the present invention, the difference from the second embodiment is mainly that: the structure of the anti-slip member 40 is different, and in this embodiment, the anti-slip member 40 is partially extended around the flange 10 itself, thereby further simplifying the structure. Specifically, the joints of the upper end surface 12 of the winding disc 10 and the front end surface 13 and the rear end surface 14 thereof extend in the direction away from the winding disc 10, respectively, so that the boss-shaped retaining pieces 40 are formed at the upper end of the corresponding second winding surface 11. In this embodiment, four positioning blocks 50 may be further added to the reel 10, the four clamping members 30 may be correspondingly pivoted to the side ends of the corresponding positioning blocks 50, and the specific structure of the positioning blocks 50 may be the same as that of the anti-release member 40 in the first embodiment. Of course, the positioning block 50 for pivotally connecting the clamping member 30 may be formed to protrude upward around the upper end surface 12 of the tray 10.
