Description

Technical Field

[0001] The utility model relates to the technical field of coil processing, in particular to a guide needle positioning mechanism with variable distance of the guide needle. Background Art

[0002] A coil usually refers to a ring-shaped wire winding. The most common coil applications include: motors, inductors, transformers, and loop antennas. The coil in the circuit refers to an inductor. It means that the wires are wound one by one, and the wires are insulated from each other. The insulating tube can be hollow, or it can contain an iron core or a magnetic powder core, which is referred to as an inductor. Inductors can be divided into fixed inductors and variable inductors. Fixed inductor coils are referred to as inductors or coils. During the winding process of the coil, guide needles are often used to provide winding support for the coil wire. In order to prevent friction damage between the coil wire and the guide needle, the guide needle should be in a rotatable state on the positioning base plate on which it is installed during the winding process. The guide needle needs to be installed and placed by a positioning mechanism.
