Claim 6:
7. A contactless card manufacturing method for manufacturing a contactless card, comprising: providing a contactless card manufacturing apparatus including: an antenna implantation device, wherein the antenna implantation device is used for implanting a copper wire into a card manufacturing base material; a chip fixing device, wherein the chip fixing device is used for placing a chip at a fixed position on the card manufacturing base material; a pin welding device, wherein the pin welding device is used for welding two ends of a wire to a pin of the chip and to the copper wire respectively; and a transmission device, wherein the transmission device is used for transmitting the card manufacturing base material among the antenna implantation device, the chip fixing device and the pin welding device, wherein the pin welding device comprises: a fixing mechanism, wherein the fixing mechanism straightens the wire and fixes the two ends of the wire, so that a middle part of the wire is kept on the pin of the chip; a solder pin; and a cutting mechanism, wherein the cutting mechanism is used for cutting off the wire, the cutting mechanism comprising a crimping knife arranged on one side of the solder pin of the pin welding device and moving up and down relative to the fixing mechanism, and when the crimping knife moves downwards, the crimping knife cutting off the wire, the cutting mechanism further comprising a limit device, which is located below the crimping knife and arranged close to the chip, and a top of the limit device is of a same height as an upper surface of the chip; wherein the contactless car manufacturing method comprising the following steps:
S1: transmitting, by the transmission device, the card manufacturing base material to the antenna implantation device;
S2: implanting the copper wire into the card manufacturing base material through the antenna implantation device;
S3: transmitting, by the transmission device, the card manufacturing base material from the antenna implantation device to the chip fixing device;
S4: placing the chip at a fixed position on the card manufacturing base material through the chip fixing device;
S5: transmitting, by the transmission device, the card manufacturing base material from the chip fixing device to the pin welding device; and
S6: welding the copper wire to the pin of the chip through the pin welding device.
