DETAILED DESCRIPTION

[0021] In order for those skilled in the art to better understand the technical scheme of the utility model, the utility model is described in detail below in combination with the drawings, and the description in this part is only exemplary and explanatory, and should not have any limiting effect on the protection scope of the utility model.

[0022] As Figures 1-3The utility model discloses a specific structure is: a kind of wire storage mechanism for flat wire alpha winding, including winding seat 21, fixed winding shaft 22 is provided on winding seat 21, fixed winding shaft is connected winding motor by transmission structure, the end of fixed winding shaft 22 is connected with fixed winding disc 23, the fixed winding shaft 22 is sleeved with wire storage gear 24, wire storage gear 24 is fixedly connected with wire storage disc 25, and the width of wire storage disc 25 is matched with the width of flat wire, wire storage position adjusting device 11 for adjusting position on fixed winding shaft 22 is cooperated with wire storage gear 24, and wire storage gear 24 can be relatively rotated with fixed winding shaft 22 when wire storage gear 24 is cooperated with wire storage drive structure 6, wire storage gear 24 is synchronously rotated with fixed winding shaft 22 when wire storage gear 24 is not in the cooperation state with wire storage drive structure 6, and the rotating direction of wire storage gear 24 when being driven by wire storage drive structure 6 is opposite with the rotating direction when being synchronously rotated with fixed winding shaft 22, wire storage position adjusting device 11 includes spring installed in the inboard of fixed winding disc 23 and position adjusting frame 28 installed in the outside of winding seat 21, another end of spring acts on wire storage disc 25, position adjusting frame 28 is provided with position adjusting cylinder 29 consistent with the trend of fixed winding shaft 22, position adjusting cylinder 29 is connected with position adjusting block 30, position adjusting block 30 is connected with two position adjusting rods 31 passing through winding stand 21, two position adjusting rods 31 are connected with position adjusting top plate 32, and position adjusting top plate 32 is installed with position adjusting roller 33 tangentially cooperated with wire storage gear 24.

[0023] When the wire needs to be stored, the position adjusting cylinder 29 drives the position adjusting block 30 and the position adjusting rod 31 to move, and then the position adjusting top plate 32 and the position adjusting roller 33 thereon push the wire storage gear 24 to move towards the fixed bobbin 23, and then the spring is in a compressed state until the wire storage gear 24 reaches the position matched with the wire storage driving structure 6, and then the wire storage gear 24 is driven to rotate by the wire storage driving structure 6 to perform the wire storage operation. At this time, the spring and the position adjusting roller 33 have an acting force on the wire storage gear and the wire storage disc integrated structure, which can avoid rotation during the wire storage process. After the wire storage is completed, the position adjusting cylinder 29 returns to the original position, and under the action of the spring, the wire storage gear 24 and the wire storage disc 25 integrated structure are pushed along the fixed bobbin 22. At this time, the wire storage gear 24 rotates synchronously with the fixed bobbin 22. To achieve the above-mentioned two states of the wire storage gear 24 and the fixed bobbin 22, the key groove and spline structure can be used, or the spline shaft and spline sleeve structure can be used. That is, when the wire storage state is reached, the fixed bobbin and the wire storage gear 24 matched part has no spline or non-spline shaft structure; when the wire release state is reached, the fixed bobbin and the wire storage gear 24 matched part has a spline or spline shaft structure. When the bobbin performs the winding, the winding rotation of the fixed bobbin drives the wire storage gear 24 and the wire storage disc 25 to rotate, and then the wire release is realized. At this time, the wire storage direction of the wire storage gear 24 needs to be controlled to be opposite to that during the wire release.

[0024] As shown in Figure 2 , the wire storage disc 25 is provided with a notch, and the side of the wire storage disc 25 close to the fixed bobbin 23 is provided with an arc-shaped lead block 26 matched with the notch. The lead block 26 is provided with a lead slot.

The pressing clamping structure 10 includes a pressing clamping cylinder 34 connected with a pressing clamping movable seat 35. The pressing clamping movable seat 35 is provided with a pressing clamping device 36 matched with the wire head pressing column 27.

[0027] When the wire storage gear 24 enters the wire storage state and the flat wire end head enters the wire storage disc 25, the pressing and clamping cylinder 34 drives the pressing and clamping movable seat 35 to move, and then the pressing and clamping device 36 clamps the wire head pressing column 27, and then the pressing and clamping movable seat 35 is continuously pushed, so that the wire head pressing column 27 is pushed into the wire storage disc 25, the pressing of the flat wire is completed, then the pressing and clamping device 36 is released, and the pressing and clamping cylinder 34 returns to the original position to avoid interference with the rotation of the wire storage. In order to ensure the continuous pressing effect of the wire head pressing column 27 on the wire head, the friction between the wire head pressing column 27 and the wire storage gear 24 needs to be designed, so that the wire head pressing column 27 is not thrown out, and the cylinder is pulled out, so that the friction does not affect the pulling out; when the wire is released, the wire head pressing column 27 needs to be pulled out.

[0028] As shown in Figure 5 The wire storage driving structure 6 includes a driving feeding cylinder 37, the driving feeding cylinder 37 includes a wire storage driving motor 38, the wire storage driving motor 38 is connected with a driving gear 39, the wire storage driving structure moves the wire storage driving motor 38 and the driving gear 39 through the driving feeding cylinder 37, so that the driving gear 39 is engaged with or separated from the wire storage gear 24.
