Description

Technical field:

[0001] The present invention relates to the technical field of inductor production, in particular to an automatic winding device for a ring-shaped common-mode inductor. Background technology:

[0002] Common-mode inductors (CMCs), also known as common-mode chokes, are commonly used in computer switching power supplies to filter common-mode electromagnetic interference (EMI). In circuit board design, CMCs also act as EMI filters, suppressing the outward radiation of electromagnetic waves generated by high-speed signal lines.

[0003] With the continuous development of current electronic technology, many electronic products require the use of common-mode inductors made of wire (usually enameled copper wire) to achieve EMI filtering and improve anti-interference capabilities.

[0004] The traditional common-mode inductor winding method involves manually winding two wires (usually enameled copper wire) around two sides of a magnetic ring, forming two coils on either side of the ring to create a common-mode inductor. However, the quality of common-mode inductors produced by this method varies greatly, and rework is often required due to poor quality. Furthermore, the labor intensity is high and the work efficiency is low, which far exceeds the growing production capacity requirements. In response to this, automatic winding machines have emerged on the market, but these machines use a cylinder to drive the lever, which is unstable and has low control accuracy, making it difficult to guarantee winding quality.

[0005] In view of this, the inventors propose the following technical solutions. Summary of the invention:

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an automatic winding device for a toroidal common-mode inductor.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions: the annular common-mode inductor automatic winding device includes a first Y-axis driving module installed on the machine platform, a first Y-axis vertical plate installed on the first Y-axis driving module and driven by the first Y-axis driving module to move in the Y-axis direction, a first Z-axis lifting plate vertically installed on the first Y-axis vertical plate in a slidable manner and a first Z-axis driving module for driving the first Z-axis lifting plate to rise and fall, a first horizontal slide rail installed on the front end surface of the first Z-axis lifting plate, a second horizontal slide rail and a forward and reverse thread screw and a first servo motor assembly for driving the forward and reverse thread screw to rotate, an installation A first drive sleeve on the positive thread section in the positive and negative thread screw, a second drive sleeve installed on the negative thread section in the positive and negative thread screw, a first fixed block installed on the first horizontal slide rail and the second horizontal slide rail and linked to the first drive sleeve, a second fixed block installed on the first horizontal slide rail and the second horizontal slide rail and linked to the second drive sleeve, a first shifting rod installed on the first fixed block and used to move or push the wire, and a second shifting rod installed on the second fixed block and used to move or push the wire. When the first servo motor assembly drives the positive and negative thread screw to rotate, the positive and negative thread screw drives the first shifting rod and the second shifting rod to move synchronously relative to each other.

[0008] Furthermore, in the above technical solution, the first Y-axis drive module includes a first Y-axis guide rail installed on the machine platform, a first screw rod distributed parallel to the first Y-axis guide rail, a first pulley installed at the end of the first screw rod, a first servo motor distributed parallel to the first Y-axis guide rail, a second pulley installed on the rotating shaft of the first servo motor, and a first belt connected to the first pulley and the second pulley, and the first Y-axis vertical plate is installed on the first Y-axis guide rail through a slider.

[0009] Furthermore, in the above technical solution, the structure of the first Z-axis driving module is the same as the structure of the first Y-axis driving module.

[0010] Furthermore, in the above technical solution, a protrusion is provided in the middle of the positive and negative thread screw to separate the positive thread section and the negative thread section.

[0011] Furthermore, in the above technical solution, a rotatable first dial wheel is provided at one side of the front end of the first dial lever, and a rotatable second dial wheel is provided at one side of the front end of the second dial lever.

[0012] Furthermore, in the above technical solution, the first dial wheel has a first annular wire-diverting groove, which is narrowed from the opening end to the inside; the second dial wheel has a second annular wire-diverting groove, which is narrowed from the opening end to the inside.

[0013] Furthermore, in the above technical solution, the inner walls on both sides of the first annular wire routing groove are both convex arc-shaped; the inner walls on both sides of the second annular wire routing groove are both convex arc-shaped.

[0014] Furthermore, in the above technical solution, the front end of the first lever is further provided with a first sensor for detecting whether there is a wire in the first dial wheel; the front end of the second lever is further provided with a second sensor for detecting whether there is a wire in the second dial wheel.

[0015] By adopting the above technical solution, the present invention has the following advantages compared to the prior art: the winding device of the present invention uses a first servo motor assembly in conjunction with a forward and reverse threaded screw to synchronously drive the first and second levers for relative movement, resulting in more stable operation and higher precision, better ensuring the quality of winding. It can also simultaneously move or push two wires, effectively improving work efficiency. Furthermore, the present invention can achieve the simultaneous winding of two coils using the first and second levers, significantly improving work efficiency, reducing labor intensity, and effectively increasing production efficiency.
