Assignee: SHANGHAI ORIENTAL MAGNETIC CARD ENGINEERING CO., LTD.
Field: Machine tools (Mechanical engineering)
Classification: CPC G  B  H | IPC B  G

Claim 8:
9. The contactless card manufacturing method according to claim 7, wherein
the solder pin is vertically arranged and moves up and down relative to the fixing mechanism, and when the solder pin moves downwards, a tip of the solder pin is pressed on the wire and the pin, wherein
the pin welding device comprises an auxiliary solder pin, wherein the auxiliary solder pin is vertically arranged and moves synchronously with the solder pin, and when the auxiliary solder pin moves downwards, a tip of the auxiliary solder pin is pressed on the wire and the copper wire; and
a cutting mechanism, wherein the cutting mechanism is used for cutting off the wire; and
step S6 comprises the following steps:
S61: providing a welding material on the pin of the chip;
S62: straightening the wire and fixing the two ends of the wire through the fixing mechanism;
S63: changing a relative position of the fixing mechanism to the chip so that the middle part of the wire abuts against the pin of the chip;
S64: abutting the tip of the solder pin against the wire and the pin and abutting the tip of the auxiliary solder pin against the wire and the copper wire to form two welding points, so that the wire is welded to the pin and the copper wire; and
S65: cutting off any side of the wire close to the welding point through the cutting mechanism.
