Description

Technical Field

[0001] The utility model relates to the technical field of magnetic winding wire stranding, in particular to a multi-station turntable stranding mechanism. Background Art

[0002] In today's world, networks are everywhere. Network transformers are the main electronic components of network equipment. In the past, the production process of network transformers included winding the T1 ring; manually tapping the T1 ring and twisting the wires; fixing the T2 ring in a special fixture and winding the T2 ring. With the advancement of technology, the winding of the T1 ring can be automated by machines. However, before winding the T2 ring, the wire ends of the T1 wire need to be tapped and then twisted, and then the T2 ring needs to be wound. The process is relatively complicated. Therefore, the manufacturing of network transformers now often requires the winding of the T1 ring to be completed by machines first. After the T1 winding is completed, the wire tail needs to be twisted before the T2 ring is wound. During the twisting process, an enameled wire needs to be added to the part of the tail wire of the T1 ring to achieve twisting. In the existing network transformer manufacturing process, the enameled wire needs to be twisted in sections before winding the T2 ring to achieve better electrical performance. In the segmentation process, the first section of the multiple enameled wires needs to be twisted into one strand, and then the scattered wire ends need to be distinguished. After the distinction, some of the enameled wires are twisted to achieve segmented twisting. Manual twisting and distinction are prone to errors, and the twisted wire quality is poor and uneven, and the efficiency is low. Utility Model Content
