Abstract
Description
Technical Field
[0001] The utility model relates to the field of production and manufacturing of magnetic ring inductors, in particular to an anti-winding mechanism for tail wires of multi-winding inductors. Background Art
[0002] The wound magnetic ring is the core component of a toroidal inductor. Due to the varying requirements of the toroidal inductor, the style of the wound magnetic ring must also be designed to align with the inductor's needs. Toroidal inductors are typically categorized as differential-mode and common-mode inductors. A differential-mode inductor is made by winding a single wire around the toroid from beginning to end, while a common-mode inductor is made by winding two wires in parallel or separately. One type of toroidal inductor currently available requires three sets of rubber wire wrapped around the toroid. Because the rubber wire itself is somewhat elastic, the tail wire of the previous layer can easily lift up during multiple windings and become entangled in the next winding, reducing the winding quality. The traditional processing method is manual processing, where the tail wire is clamped by hand to prevent it from getting entangled. However, manual processing efficiency is too low to meet the needs of modern production and processing. Currently, self-rotating inductor winding machines are commonly used on the market for multi-winding inductor processing, but there is no mechanism to prevent the tail wire from getting entangled. The tail wire still needs to be held manually, which does not meet the requirements of automated production equipment and also poses certain risks to operators. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the existing technology and provide a multi-winding inductor tail wire anti-winding mechanism that can be used in conjunction with an inductor self-rotating multi-winding winding device to effectively prevent the tail wire from winding, thereby improving production efficiency and winding yield.
[0004] The technical solution adopted by the present invention is: the present invention includes a base and a winding chamber opened on the base, and also includes at least two groups of tail wire clamping modules arranged on the base, the tail wire clamping modules include a support frame, a vertical screw rod arranged on the support frame, a vertical slider slidingly matched with the vertical screw rod, a horizontal cylinder arranged on the vertical slider and a clamping scissors driven by the horizontal cylinder, a stop structure is also provided on the clamping scissors, and the two groups of the clamping scissors are relatively arranged in the winding chamber.
[0005] Furthermore, the clamping scissors are composed of a stationary knife and a movable knife. The stationary knife is fixedly arranged on the vertical slider through a connecting piece. The movable knife is rotatably connected to the stationary knife through a rotating pin and is fixedly connected to the output end of the horizontal cylinder at the top.
[0006] Furthermore, the stop structure adopts an L-shaped baffle, wherein the top of the long end is rotatably connected to the stationary knife through a second rotating pin, and the short end is horizontally arranged between the stationary knife and the movable knife, and the connection point between the stop structure and the stationary knife is lower than the connection point between the stationary knife and the movable knife.
[0007] Furthermore, the planes where the two groups of tail wire clamping modules are located are perpendicular to each other, an auxiliary wire pushing structure is provided on any one group of the tail wire clamping modules, and a winding tool moving structure is provided on the other group of the tail wire clamping modules.

[0009] Finally, the winding tooling movable structure includes a movable bracket fixedly arranged at the bottom of the corresponding support frame, a movable cylinder fixedly arranged on the movable bracket, and a tooling clamp connected to the output end of the movable cylinder, and the tooling clamp can move inside and outside the winding chamber.
[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention is designed for multi-winding inductor self-rotating winding equipment, so as to avoid the problem of subsequent winding being entangled due to the elastic warping of the leather wire when the inductor is wrapped around the leather wire. Specifically, the tail wire is clamped by two groups of tail wire clamping modules arranged on the base. The inductor self-rotating tooling is now installed on the tooling fixture, and the inductor self-rotating tooling is brought into the winding chamber by the mobile cylinder. After the first group of wires is wound, two groups of tail wires are naturally generated on both sides of the inductor. At this time, the output end of the horizontal cylinder extends outward, pushing the movable knife to rotate on the static knife, and the lower end opens. The vertical screw starts and drives the vertical slider to move downward to the tail wire position. The output end of the horizontal cylinder is recovered, and the lower end of the clamping scissors is tightened to clamp the tail wire. Then the vertical screw is reset, and the tail wire is pulled up, and then the next group of leather wires are wound to avoid the problem of tail wire entanglement. Therefore, the utility model can be used in conjunction with an inductive self-rotating multi-winding winding device to effectively prevent the tail wire from being entangled, thereby improving production efficiency and winding yield.

[0014] like Figure 1 、 Figure 2 and Figure 3As shown, the utility model includes a base 1 and a winding chamber 2 opened on the base 1, and also includes at least two groups of tail wire clamping modules 3 arranged on the base 1, the tail wire clamping module 3 includes a support frame 30, a vertical screw rod 31 arranged on the support frame 30, a vertical slider 32 slidingly matched with the vertical screw rod 31, a horizontal cylinder 33 arranged on the vertical slider 32, and a clamping scissors driven by the horizontal cylinder 33, and a stop structure is also provided on the clamping scissors. The two groups of the clamping scissors are relatively arranged in the winding chamber 2. In this embodiment, the clamping scissors are composed of a static knife 34 and a movable knife 35. The static knife 34 is fixedly arranged on the vertical slider 32 by a connecting member 36, and the movable knife 35 is rotatably connected to the static knife 34 by a rotating pin 37, and the top is fixedly connected to the output end of the horizontal cylinder 33.
[0015] In the present invention, the stop structure utilizes an L-shaped baffle, with the top of the long end 38 pivotally connected to the stationary blade 34 via a second pivot pin 39. The short end 300 is positioned horizontally between the stationary blade 34 and the movable blade 35. The connection point between the stop structure and the stationary blade 34 is lower than the connection point between the two blades. The planes on which the two sets of tail wire clamping modules 3 lie are perpendicular to each other. An auxiliary wire pushing structure is provided on one set of the tail wire clamping modules 3, while a winding tooling movable structure is provided on the other set of the tail wire clamping modules 3.
[0016] In the present invention, the auxiliary wire pushing structure includes a wire pushing bracket 4 fixedly arranged at the bottom of the corresponding support frame 30, a wire pushing cylinder 5 is arranged on the wire pushing bracket 4, a wire pushing head 6 is fixedly arranged on the output end of the wire pushing cylinder 5, and the plane where the wire pushing head 6 is located is parallel to the plane where the corresponding clamping scissors are located. The winding tooling moving structure includes a moving bracket 7 fixedly arranged at the bottom of the corresponding support frame 30, a moving cylinder 8 fixedly arranged on the moving bracket 7, and a tooling fixture 9 connected to the output end of the moving cylinder 8, and the tooling fixture 9 can move in and out of the winding chamber 2.
[0017] The present invention is designed for a multi-winding inductor self-rotating winding device to avoid the problem of subsequent winding being entangled due to the elastic warping of the leather wire when the inductor is wrapped around the leather wire. Specifically, the tail wire is clamped by two groups of tail wire clamping modules 3 arranged on the base 1. The inductor self-rotating tooling is now installed on the tooling clamp 9. The inductor self-rotating tooling is brought into the winding chamber 2 by the moving cylinder 8. After the first group of wires is wound, two groups of tail wires are naturally generated on both sides of the inductor. At this time, the output end of the horizontal cylinder 33 extends outward, pushing the movable knife 35 to rotate on the static knife 34, and the lower end opens. The vertical screw rod 31 starts and drives the vertical slider 32 to move downward to the tail wire position. The output end of the horizontal cylinder 33 is recovered, and the lower end of the clamping scissors is tightened to clamp the tail wire. Then the vertical screw rod 31 is reset, and the tail wire is pulled up, and then the next group of leather wires are wound to avoid the problem of tail wire entanglement. Due to the positional relationship of the winding tooling moving structure, after completing one layer of winding, one of the tail wires can naturally be clamped by one group of the tail wire clamping modules 3, and the position of the tail wire at the other end will deviate. At this time, the auxiliary wire pushing structure starts to work, and the wire pushing cylinder 5 drives the wire pushing head 6 toward the clamping scissors in the corresponding tail wire clamping module 3 to assist it in clamping the tail wire, so as to complete the clamping of the two groups of tail wires and better avoid the problem of tail wire entanglement during the winding process.
[0018] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
