Description

Technical Field

[0001] This invention relates to a square magnetic core winding and pulling wire assembly mechanism. Background Technology

[0002] Square magnetic cores are named for their square shape, formed by two parallel core pillars. Traditionally, winding these cores using conventional hook winding methods is difficult because the winding of one core is blocked by the other, hindering completion. Therefore, a common practice is to separate the two core pillars, winding each pillar individually before reassembling them. However, this method divides the winding process into three steps: left winding, right winding, and assembly, significantly increasing complexity, equipment costs, and overall efficiency. Furthermore, the wound core requires wire pulling and alignment to position the wire into clamps at both ends for subsequent soldering. Therefore, designing a mechanism that sequentially pushes the wire through the two core pillars of a square magnetic core, pulls it into place, and clamps the wire into the clamps is essential. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a square magnetic core pushing and pulling wire assembling mechanism that can sequentially push and form wire winding, pull wire feet into place, and press wire feet of a square magnetic core with two core pillars.

[0036] During work:

[0037] The square magnetic core 8 is fitted onto the bottom mold 42. Then, the upper mold cover 52, driven by the first pressing cylinder 51, presses the cover onto the bottom mold base 41, i.e., the upper mold 53 is fitted onto the bottom mold 42. At the same time, the upper mold product placement slot 531 is fitted onto the square magnetic core 8. The external wire feeding equipment feeds the wire into the wire guide channel 453 of the angled wire feeding wing plate 45. The wire 9 enters the angled wire feeding channel and the first lead wire thread groove of the module in sequence through the wire feeding guide channel 453. The first section of the wire 9 advances along the first lead wire thread groove and forms a layer of threaded coil around the product magnetic core column, wrapping the magnetic core column of the product. The external wire feeding device continuously feeds and pushes the wire, which advances along the first lead thread groove and forms a threaded coil around the product's magnetic core pillar. The already formed threaded coil rotates and rises along the product's magnetic core pillar under the push of the subsequent forming until the entire thread surrounds the product's magnetic core pillar, completing the wire pushing and winding forming of the two magnetic core pillars of the square magnetic core 8. Then, the wire pushing and winding upper mold cover 52 is reset under the action of the first pressing cylinder 51.

[0038] The bottom mold conveying cylinder 31 drives the bottom mold base 41 to move below the upper mold cover 62. The second pressing cylinder 61 drives the upper mold cover 62 to press down onto the bottom mold base 41, so that the upper mold 63 is pressed onto the bottom mold 42. At this time, the pull end of the first upper mold pull member 1 and the pull end of the second upper mold pull member 2 are respectively placed between the horizontally placed wires at both ends of the square magnetic core 8. Then, the two upper mold pull cylinders 64 start simultaneously and drive the first upper mold pull member 1 and the second upper mold pull member 2 to separate. During the separation process, the pull end of the first upper mold pull member 1 and the pull end of the second upper mold pull member 2 respectively straighten the wires at both ends of the square magnetic core 8, so that the ends of the wires at both ends are vertically distributed along the two ends of the square magnetic core 8, completing the wire pulling action of the wires at both ends of the square magnetic core 8. Then, the upper mold cover 62 is reset under the action of the second pressing cylinder 61.

[0039] The bottom mold conveying cylinder 31 drives the bottom mold base 41 to move below the upper mold cover 72. The third pressing cylinder drives the upper mold cover 72 to press down onto the bottom mold base 41, so that the upper mold component 73 is pressed onto the bottom mold 42. During the pressing process, the four wire leads 732 on the upper mold component 73 are respectively aligned with the four wire leads on both ends of the square magnetic core 8 and the four metal clips 81 on both ends of the square magnetic core 8. In the early stage of the pressing process, the four wire leads fall into the four pressing wire positions 733 along the curved edge of the pressing wire position 733. In the later stage of the pressing process, the four wire leads are respectively guided by the four pressing wire positions 733 and pressed into the four metal clips 81 on both ends of the square magnetic core 8, completing the wire assembly action. Finally, the upper mold cover 72 is reset under the action of the third pressing cylinder. During the pressing process, the buffer spring 74 acts as a buffer for the mold 73 on the whole line, preventing the mold 73 on the whole line from pressing hard on the bottom mold 42 and damaging the square magnetic core 8.

[0040] This invention is applicable to the field of square magnetic core winding.
