Description

Winding device and method for winding a component with a wire and winding machine Technical Field The present invention relates to a winding device and a method for winding a component with a wire and a winding machine. Background In order to optimize the compactness of the component to be wound, such as the stator, it may be advantageous to arrange the interconnecting wires in a delta-series connection or a star-series connection opposite the connection side of the U/V/W. In this way, fewer wire crossings and normal wire accumulation are formed. Since the needle carrier inserted from one side then has to be able to wind the wire on the outer diameter of the stator on the opposite side, it may be advantageous for the winding nozzle to have an expanded degree of freedom. In this respect, DE 10 2004 028 566 A1 relates to a winding device having a receptacle with a parallelogram guide for selectively setting different operating positions of the winding needle. In order to achieve a pivot axis which coincides with the wire outlet opening on the winding needle during the pivoting movement of the winding needle, so that the working position can be changed without affecting the wire tension and the wire path, the two lever arms of the parallelogram guide are connected by two pivot elements embodied as pivot plates, wherein the pivot axis of the pivot elements is arranged on the housing so as to be pivotable transversely with respect to its longitudinal axis. In this way, by introducing a parallel displacement of the two parallel lever arms of the parallelogram guides with a common drive with push rods, a lateral displacement of the parallelogram guides is achieved at the same time, so that no further actuation means are required. A pivot angle range of up to 90 ° can be achieved. In document DE 10 2011 008 662 A1, a needle winding system for winding a carrier to be wound, in particular a stator, an armature or a rotor of an electric motor with distributed windings, comprises a winding head which is translatably movable in longitudinal and transverse directions, and a needle carrier system with an outlet wire nozzle and a wire guide. U.S. patent document 10,944,311 B2 discloses a nozzle rotation device having a nozzle unit including a nozzle for ejecting a wire from a tip thereof and a nozzle holder for holding the nozzle, wherein the nozzle unit rotatably supports the nozzle holder, and a nozzle holder driving member that is provided integrally with the nozzle unit and moves in the nozzle unit to rotate the nozzle holder. In document JP 2011-004477A, a further method for winding a wire is described. In document JP 2003-169 455A nozzle holder, a nozzle rotation unit and corresponding devices and methods are disclosed.
