[0002] The ignition coil is a core component of an ignition system of a power-driven motor, and is mainly used for converting low voltage of a storage battery into high voltage to generate an electric spark to ignite mixed gas in a cylinder and drive the motor to operate.

[0003] When the coil is produced and processed, the outer wall of the iron core needs to be wound with a coil, and a winding group needs to be matched to complete the winding work. When the existing winding device winds the coil, the moving speed of the wire guide mechanism needs to be adjusted during reciprocating wire guiding, so that the moving speed of the wire guide mechanism is matched with the winding speed of the winding motor, otherwise uneven winding may occur, and in severe cases, the wire may be pulled. Before winding, the wire end is not conveniently and stably supported and positioned, because the wire end of the ignition coil needs to be left with a certain length, and the wire end left during winding will be continuously swung, and part of the wire end will be damaged. Therefore, the application provides a coil winding group for an ignition coil. CONTENT OF THE UTILITY MODEL
