Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging coil winding devices, in particular to a wireless charging coil positioning winding device. Background Art

[0002] Wireless charging coil is an important component used in wireless charging technology. It is a coil structure made of conductive material, usually one or more coils wound in a spiral or toroidal shape. In the wireless charging system, the electrical energy is transmitted from the charger to the receiver through the principle of electromagnetic induction, and then converted into current to supply the device for charging.

[0003] When the existing wireless charging coil winding device is winding the coil, the coil pay-off mechanism is affected by the faster rotation speed of the driving motor at the coil winding mechanism, so that the coil pay-off mechanism may cause the coil to pay-off too fast due to the large inertia and the too fast rotation speed. The coil unwinding process lacks uniformity and orderliness, causing the coils to cross and tangle with each other, thereby affecting the uniformity of the electromagnetic field distribution and reducing the efficiency of wireless charging. At the same time, if the coil pay-off speed is too fast, the wireless charging coil may easily become loose when being wound. The loose coil may cause poor contact between the coils, affecting the energy transmission efficiency and reducing the yield rate of the wireless charging coil. Therefore, it is necessary to improve a wireless charging coil positioning and winding device to solve the above problems. Utility Model Content
