Description
Technical Field
[0001] The utility model relates to the field of production and manufacturing of magnetic ring inductors, in particular to a magnetic ring retaining mechanism with a wire clamping function. Background Art
[0002] Wirewound toroids are the core component of toroidal inductors. To meet the varying needs of toroidal inductors, the toroidal winding style must be designed to match the desired inductor specifications. Toroidal inductors are typically categorized as differential-mode and common-mode. A single wire wound from end to end around the toroid is considered a differential-mode inductor, while a two-wire winding, bifilar or split-wound toroid is considered a common-mode inductor. In traditional processing technology, the winding of magnetic ring inductors is mostly done manually. The magnetic ring is placed on a winding table and fixed with a clamp. Then the enameled wire is manually wound around the magnetic ring in circles. This winding process is inefficient and highly dependent on the workers' proficiency, which cannot meet production needs. With the development of technology, automatic winding equipment has gradually replaced manual winding to improve production efficiency. However, there is a problem of tail wire entanglement during the winding process of the robotic arm, resulting in a low winding yield rate of the product. Therefore, it is necessary to add a wire clamping mechanism to the winding station, which greatly increases the size and use cost of the equipment. At the same time, it also makes the automatic winding process more complicated and increases the failure rate of winding. Utility Model Content

[0022] The present invention is applied to the automatic winding equipment of magnetic ring inductors.

At this time, the transverse cylinder moves the wire feeding module to the top of the magnetic ring and starts feeding the wire. When the wire passes through the magnetic ring to the position of the wire pulling clamp 33, , the wire pulling cylinder 32 starts and drives the wire pulling clamp 33 to clamp the wire end, and the wire pulling slide 30 drives the wire pulling slider 31 to move downward according to the winding length preset by the system.

The driving cylinder 21 starts, and the output shaft 25 extends upward. Under the drive of the wire clamping linkage rod 22, the clamping head 24 swings downward and pushes the wire end into the wire storage groove 29 for clamping. The wire cutting cylinder 102 starts and controls the wire cutting head 103 to cut the wire, and the winding equipment performs subsequent winding work. During the process, the wire clamping head 24 always clamps the tail wire, effectively avoiding the problem of tail wire entanglement. The first vertical cylinder 12 and the second vertical cylinder 14 play the role of fine-tuning alignment.
