Coil winding module and coil winding device

The invention relates to a module and a device for winding a coil, in particular to a coil winding module and a coil winding device capable of improving product quality.

Radio Frequency Identification (RFID) is a technology that uses radio frequency transmission waves as object identification to provide tracking of goods, goods, and even animals. It also enhances the convenience of warehousing and logistics management. In the transportation, manufacturing, management and animal research industries. In particular, in the radio frequency identification system, the coil is used as an important medium for data transmission and reading and reception. The radio frequency identification system generates a receiving coil by using a magnetic flux generated by a current through the transmitting coil. The magnetic field changes to exchange information between the transmitting coil and the receiving coil; if you want to improve the transmission rate and prevent data transmission errors, you should use a high-performance, high-reliability coil.

In addition, in recent years, the wireless power (WP) technology, which is attracting attention, mainly uses near-field sensing (ie, inductive coupling), and the wireless charging charger transmits energy to the powered device. In detail, in the wireless charging system, a coil is disposed in the wireless charging charger, and an alternating current electromagnetic field is generated by driving the alternating current, and another coil is disposed in the electric device to receive the alternating electromagnetic field and converted. It is electric energy, and thus the battery in the electric device is charged by the electric energy. Therefore, high-performance, high-reliability coils are also one of the key factors to improve wireless charging efficiency.
