Abstract

The invention provides an IC card annular coil winder which comprises a conical winding body, a tip cone used in cooperation with the winding body and a spiral column installed on the winding body, the interior and the exterior of the winding body are both of a conical structure, and a tip cone hole used for allowing the tip cone to be inserted is formed in the center line of the winding body. A spiral hole of a spiral structure is formed in the winding body, the screw pitch of the spiral hole is the same as that of the spiral column, the winding body, the spiral column and the tip cone are detachably installed, a take-up plate used for wire unwinding is installed at the bottom of the winding body, and elastic contraction gaskets are installed at the joint position of a stepped hole of the spiral hole. Opposite surfaces of the contraction gaskets are respectively connected with the spiral hole and the spiral column; according to the invention, the production process and the production precision are improved, the precise and fine copper ring is more stably used in the IC card chip, the design precision is improved, the material waste is reduced, the service life of the product is prolonged, and the quality of precise production is improved.

Description

technical field [0001] The invention relates to the technical field of coil winding, in particular to an IC card ring coil winding device. Background technique [0002] The IC card realizes the functions of storage and information transmission through a tiny chip. The chip of the IC card is very small, usually compressed in a small space, and uses radio frequency technology for signal transmission. The IC card chip of the terminal is through The form of copper coil forms an induction current in the radio frequency circuit to activate the induction circuit. The induction current enters the induction circuit and sends the stored simple information to the receiving device. The most important thing for an IC card is the number of turns of the coil and the compactness of the coil. At present, the winding of the coil is realized by rotating the mold and the wire drawing equipment on the plane. The mold is simple, but it is easy to break the wire, and the spacing of the coil windin...
