Abstract:
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).
Abstract:
The invention relates to an apparatus and a method for transferring a plurality of chips (6) from a wafer (1) to a substrate, in particular a web (15), wherein at least one first wheel (2) or at least one first roller for successively picking up the chips (6) on its outer circumference (3) by means of a rotational movement (5) of the first wheel (2) or the first roller is provided.
Abstract:
The invention relates to a device for printing at least one web that is driven continuously through said device, in addition to a method for printing said web. At least one unit (12, 13, 14) is integrated into the device (1) for the continuous transfer of individual transponders (10) or transponder parts (10a), which operate according to the radio frequency identification principle, from at least one continuous carrier belt (8) to the web (2). During said process, the running speed of the carrier belt (8) is adapted to the running speed of the web (2), the latter speed being predetermined by the printing process. A connection device (11, 11a, 11b, 11c) connects the transponders (10) or transponder parts (10a) to the web (2) in a predetermined section of the carrier belt (8) and the web (2), when the speeds have been synchronised.
Abstract:
The invention relates to an apparatus for testing the reading reliability of smart labels (3), having a reader (6), a transport device (2) arranged at a distance from the reader (6), for receiving and transporting the smart labels (3), and a device for setting the transmission power of the reader (6), the reader (6) having a reader antenna (7) whose distance (d) from the transport device (2) can be altered.
Abstract:
The invention relates to a method for producing thin-film solar modules, comprising the following steps: providing flexible thin-film solar cells as separate segments in a container or on a web wound up to a roll, the flexible thin-film solar cells bearing with a first side against the web, wherein each of the flexible thin-film solar cells is designed to have a first electric pole and a second electric pole; transferring the flexible thin-film solar cells from the web to a first film web such that the first pole of a first flexible thin-film solar cell is positioned next to the second pole of a second flexible thin-film solar cell; and applying electrically conductive contact strips to the first and second poles of the flexible thin-film solar cells in longitudinal and/or transverse direction relative to the conveying direction of the first film web in order to electrically connect the flexible thin-film solar cells in a serial and/or parallel manner; laminating a transparent flexible second thermoplastic film web onto the first film web and the flexible thin-film solar cells in order to form a solar module strand formed by the first and second film webs and the flexible thin-film solar cells located therebetween; separating the plurality of thin-film solar modules from the solar module strand formed; and feeding these separated thin-film solar modules to a crosslinking station.
Abstract:
The invention relates to a method and a measuring device for contactless testing of the electromagnetic properties of an antenna with the aid of said measuring device. The antenna, when fitted with a chip, can form a transponder for an identification system. The inventive method comprises the following steps: an electromagnetic measuring field of a given frequency is emitted by a transmitting antenna of the measuring device, the antenna arranged in the measuring field is tested at said given frequency, the test results for the antenna are evaluated by comparing them with a reference value. According to the invention, the antenna is measured in a non-fitted state.
Abstract:
A thin-film solar module can have the following features: a first film web; a sequence of electrically conductive contact points arranged at a distance from one another on the first film web with respective first and second regions; a sequence of flexible thin-film solar cells which has a first side that is designed as a first pole at least in certain regions and a second side that is designed as a second pole at least in certain regions, a photovoltaically active layer structure, a flexible sealing layer located on the first side of the layer structure, and at least one electrical conductor located between the layer structure and the sealing layer and contacting the first pole, wherein the flexible sealing layer and the electric conductor protrude laterally past the photovoltaically active layer structure; wherein the thin-film solar cells are arranged on the first film web such that the second pole contacts a first contact point of the contact points on the first film web in the first region and the electric conductor contacting the first pole contacts a second contact point adjacent to the first contact point on the first film web in the second region.
