[0050] The traditional way of winding magnetic rings is a crochet hook mode. If you need to wind multiple layers of large-diameter magnetic rings, you need to hook the copper wire under the crochet hook for each circle. The friction between the hook and the copper wire is sliding friction. The hook exerts a certain force on the copper wire for each circle. When the diameter of the wound copper wire is large and the rhythm is fast, the force exerted by the hook on the copper wire will accumulate when the number of circles is too many. The accumulated force will thin the diameter of the copper wire, reduce the cross-sectional area, and increase the overall resistance, seriously affecting the quality requirements of the product. The method of tightening both ends can reduce the tension on the copper wire by 30% to 50%.

[0051] The present invention divides the tensioning of the copper wire into two stages and adds a tensioning wheel as a buffer module, thereby reducing the overall force on the copper wire when it is tensioned, reducing the total tension on the copper wire when the magnetic ring is completely wrapped, reducing the reduction in the diameter of the copper wire, reducing the resistance value, and improving the qualified rate.
