METHOD AND DEVICE FOR PRODUCING SELF-ADHESIVE RFID TRANSPONDERS

摘要

The invention relates to the production of self-adhesive RFID transponders, in which RFID chips are successively bonded to antennae. The method comprises the following steps: a) an antenna strip (13) is advanced with a self-adhesive first carrier strip (18) at an identical speed; b) the chips are applied to the antenna strip (13) by means of an application unit (17), to form a large number of RFID transponder inlays, each chip being allocated to one respective antenna (15) and making electrical contact with the latter by means of a contact device (17); c) the antenna strip (13) and the carrier strip (18) are then joined and the carrier strip (18) is laminated onto the antenna strip (13) by means of a lamination device (23, 24), in such a way that the carrier strip (18) covers the antennae (15) and the chips; d) each RFID transponder inlay is die-cut using a die cutting unit (25, 26), which severs the antenna strip (13) without severing the carrier strip (18), to form transponders (30a); and e) the sections (28) of the antenna strip (13) that are devoid of antennae are removed from the carrier strip (18), leaving intact the carrier strip (30) that supports the die-cut RFID transponders (30a).
