[0001] The utility model relates to the technical field of charger production, in particular to a charger wire winding device. Background Technique
[0002] A charger mainly consists of a stable power supply plus necessary control circuits such as constant current, voltage limit, and time limit. The charger coil is a key component in the charger, and it plays an important role in both wireless charging and wired charging. The charger wire winding device is one of the indispensable important devices in the electronic manufacturing industry.
[0003] The principle of the charger wire winding device mainly involves two aspects: electromagnetic induction and precision mechanical control. Through the application of precise mechanical control and the principle of electromagnetic induction, the charger coil winding device can efficiently produce charger coils that meet the requirements, providing strong support for the production of chargers.
[0004] Most of the existing machine wire winding methods are to respectively set a manipulator on both sides of a ring-shaped inductive iron core, push out the inductive coil and then pass it through, rather than being able to continuously wind the wire like winding a bar-shaped inductive iron core. Such a wire winding method has a very slow wire winding speed and low production efficiency; therefore, a charger wire winding device is proposed to solve the above problems. Content of the Utility Model

[0008] Preferably, a driving motor is arranged on one side of the lower end of the arc-shaped mounting frame. A driving wheel is fixedly installed on the rotating shaft of the driving motor. The two guide wheels, the tensioning wheel and the driving wheel on the outer side of the lower end of the arc-shaped mounting frame are rotationally matched through a belt, and the part of the belt between the two guide wheels is tangent to the wire winding ring.
