Description

technical field [0001] The invention belongs to the field of transformer production equipment, in particular to a copper wire unwinding system and a use method for winding transformer coils. Background technique [0002] In the automatic production process of transformer coils, the copper wire needs to be wound on the iron core. In the process of winding the copper wire, the basic process adopted is: first, the copper wire coil is stored on the material rack, and then the The end of the copper wire is connected to the iron core to be wound, and finally, the iron core is driven to rotate, and then the copper wire is pulled to be wound on the iron core. [0003] In the above-mentioned copper wire winding process, there is insufficient tension of the copper wire, which leads to the loose winding of the copper wire on the iron core, which affects the performance of the transformer; in addition, due to the thicker diameter of the copper wire, when it is pulled from the After unw...
