Description

Technical Field

[0001] This utility model relates to the technical field of magnetic ring winding processing equipment, and in particular to a magnetic ring inductor rotary wire feeding mechanism. Background Technology

[0002] During the winding process of a magnetic ring inductor, in order to prevent the end of the metal wire (i.e., copper wire) from coming loose and to ensure stable winding in the early stages, and to prevent the copper wire from shifting in the early stages, one end of the wire (hereinafter referred to as the wire end) needs to be tightened during the winding process. However, the magnetic ring will move during the winding process, for example, the position of the magnetic ring will rotate during the winding.

[0003] An existing long-wire magnetic winding equipment and process, with application number CN202310900455.8, includes a worktable, a copper wire feeding mechanism, a copper wire compression and winding mechanism, a coil loading and unloading mechanism, a coil clamping and rotating mechanism, and a copper wire winding hooking mechanism. The copper wire feeding mechanism, copper wire compression and winding mechanism, coil loading and unloading mechanism, coil clamping and rotating mechanism, and copper wire winding hooking mechanism are all set on the worktable.

[0004] The aforementioned magnetic ring winding device includes a winding lever assembly. Referring to

[0031] in the specification and Figure 6, it can be seen that the winding lever assembly relies on left-right and up-down transmission components to achieve winding. However, the movement of the wire end during the winding process is relatively mechanical and requires coordinated movement to match the movement during magnetic ring winding. Single left-right or up-down movement can lead to insufficient wire end traction or misalignment within a single winding unit. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic ring inductor rotary wire feeding mechanism to overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The eccentric rotary wire feeding assembly includes a wire feeding guide for outputting metal wire, and the wire feeding guide and the longitudinal output shaft are arranged non-coaxially.

It is worth noting that there is only one rotary drive assembly; the two reducers are connected via transmission elements, so the rotary drive assembly only needs to be connected to one of the rotary drive assemblies.

[0013] To elaborate further, each of the two reducers includes a transverse input shaft. The transverse input shafts of the two reducers are connected by a reducer connecting shaft and a pair of swivel couplings.

[0015] To elaborate further, the wire feeding guide rail fixing plate is equipped with a lifting motor, the output end of the lifting motor is fixedly equipped with a coupling, one end of the bottom of the coupling is connected to a lead screw, the lead screw is fitted with a lead screw fixing seat, the lead screw fixing seat is threadedly connected to the lead screw, the lead screw fixing seat is fixedly connected to the wire feeding slider, the wire feeding slider is also fixedly equipped with a pair of wire feeding reinforcing ribs, the wire feeding reinforcing ribs are fixedly connected to the reducer fixing plate.

The wire clamping cylinder is slidably connected to the wire feeding guide rail fixing plate through the wire feeding slider and the wire feeding guide rails.

The magnetic ring is circular, and the tightening end and the wire feeding end of the eccentric rotary wire feeding assembly can rotate along the trajectory of the magnetic ring. Therefore, this invention can achieve the purpose of the wire end following the rotation of the magnetic ring, thereby improving the stability and accuracy of magnetic winding.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings:

[0028] like Figs. 1-3 As shown, this embodiment provides a magnetic ring inductor rotary wire feeding mechanism, which can effectively solve the problems of loose wire end traction or misalignment of the winding of metal wire (copper wire) during the magnetic ring winding process in the prior art. Through the coordinated design of the eccentric rotary wire feeding component, lifting mechanism, wire clamping component and rotary drive component, the function of stable wire feeding and following the rotation of the magnetic ring winding is realized.

[0029] The rotary wire feeding mechanism includes a reducer mounting plate 8 and a pair of reducers 6 symmetrically arranged on the reducer mounting plate 8. Each reducer 6 includes a longitudinal output shaft 12 and a transverse input shaft, wherein the longitudinal output shaft 12 passes through the reducer mounting plate 8 and is fixedly connected to the eccentric rotary wire feeding assembly. Specifically, one bottom end of the longitudinal output shaft 12 passes through the reducer mounting plate 8 and is fixedly connected to the eccentric rotary wire feeding assembly via a wire feeding shaft fixing block 14. The top of the wire feeding shaft fixing block 14 is fixedly connected to the longitudinal output shaft 12, and a wire feeding shaft 15 is fixedly mounted at the bottom of the wire feeding shaft fixing block 14. An opening is provided at one bottom end of the wire feeding shaft 15, and a wire feeding guide pin 16 arranged coaxially is fixedly mounted at the opening. Both the wire feeding guide pin 16 and the wire feeding shaft 15 are of a through-hole structure, used for outputting metal wire. In order to ensure smooth transmission of the metal wire, a ceramic eye 13 is inserted at the bottom port of the longitudinal output shaft 12. The ceramic eye 13 and the longitudinal output shaft 12 are arranged coaxially and are both of the through-type structure to ensure the smoothness and stability of the metal wire during transmission.

[0030] Furthermore, the mechanism also includes a lifting mechanism for lifting the reducer fixing plate 8 and the eccentric rotary wire feeding assembly as a whole, adapting to winding requirements at different heights. The lifting mechanism includes a wire feeding guide rail fixing plate 7, on which a pair of wire feeding guide rails 20 are fixedly mounted. The wire feeding slider 18 is slidably connected to the wire feeding guide rail fixing plate 7 via the wire feeding guide rails 20, and the reducer fixing plate 8 is fixedly mounted on the wire feeding slider 18. The wire feeding slider 18 is also fixedly equipped with a pair of wire feeding reinforcing ribs 19, which are fixedly connected to the reducer fixing plate 8 to enhance the stability of the overall structure. The lifting motor 1 is mounted on the wire feeding guide rail fixing plate 7, and the output end of the lifting motor 1 is connected to the lead screw 21 via a coupling 17. The lead screw 21 is fitted with a lead screw fixing seat 23, which is threadedly connected to the lead screw 21 and fixedly connected to the wire feeding slider 18. This enables the lead screw 21 to rotate via the lifting motor 1, thereby driving the wire feeding slider 18 to slide up and down along the wire feeding guide rail 20, thus realizing the overall lifting of the reducer fixing plate 8 and the eccentric rotating wire feeding assembly.

[0031] Specifically, a wire clamping assembly is installed on the top of the reducer mounting plate 8 for clamping the metal wire and stabilizing its feeding. The wire clamping assembly includes a wire clamping cylinder fixing block 4, which is fixed to the top of the reducer 6. A wire clamping cylinder 2 is fixedly mounted on the side wall of the wire clamping cylinder fixing block 4. Wire clamping urethane adhesive 3 is fixedly mounted on the piston rod end and positioning part of the wire clamping cylinder 2 to achieve flexible clamping of the metal wire. The wire clamping urethane adhesive 3 is made of a material with good flexibility and adhesion, providing sufficient friction when clamping the metal wire to prevent it from loosening or shifting during feeding, while minimizing surface damage to the metal wire.

[0032] In addition, a rotary drive assembly is installed on one side of the reducer mounting plate 8 to drive the eccentric rotary wire feeding assembly to rotate relative to the reducer mounting plate 8. The rotary drive assembly includes a wire feeding motor mounting plate 5, which is fixed on the reducer mounting plate 8 and has a wire feeding motor 11 mounted on it. The wire feeding motor 11 is connected to the transverse input shaft of the reducer 6 via a pulley and belt. The transverse input shafts of the pair of reducers 6 are connected by a reducer connecting shaft 9 and a pair of cloverleaf couplings 10 to ensure that the two reducers 6 operate synchronously. Specifically, each of the opposite transverse input shafts of the pair of reducers 6 is fixedly equipped with a cloverleaf coupling 10, and the cloverleaf couplings 10 are connected by a fixed reducer connecting shaft 9, thereby enabling a single wire feeding motor 11 to drive the two reducers 6 to rotate synchronously, simplifying the transmission structure and improving the reliability and efficiency of the equipment.

[0033] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
