Description
Spezieller Transponder zur Verwendung auf oder in metallischer Umgebung sowie in erhöhter TemperaturumgebungSpecial transponder for use on or in metallic environments and in elevated temperature environments
2.2 Stand der Technik2.2 State of the art
Elektronische Transponder bestehen üblicherweise aus einer Spule und einem elektronischen Transponder-Chip sowie einem Resonanzkondensator, welcher üblicherweise vom Hersteller-Werk aus in den Transponder-Chip integriert ist.Electronic transponders usually consist of a coil and an electronic transponder chip as well as a resonance capacitor, which is usually integrated into the transponder chip by the manufacturer.
Diese beiden Bauteile werden üblicherweise in Plastikteile wie Münzen und Schlüsselanhänger oder Plastikkarten eingelegt und verklebt oder laminiert. Transponder werden heutzutage in zahlreichen Gebieten eingesetzt wie beispielsweise in Zeiterfassungen, Lagerlogistik und zur Prozessdatenerfassung.These two components are usually inserted into plastic parts such as coins and key chains or plastic cards and glued or laminated. Transponders are used today in numerous areas such as time recording, warehouse logistics and process data acquisition.
2.3. Problem2.3. Issue
Den im Schutzanspruch 1 angegebenen Transpondern liegt das Problem zugrunde, einen Transponder zu schaffen, der auch in einer Umgebung eingesetzt und gelesen werden kann, bei welcher der Transponder normalerweise durch metallische Einflüsse in seiner Funktion beeinflusst oder gar komplett gestört wird.The transponders specified in claim 1 are based on the problem of creating a transponder that can also be used and read in an environment in which the transponder's function is normally influenced or even completely disrupted by metallic influences.
Weiterhin war ein Transponder zu schaffen, welcher auch in rauen Bedingungen (beispielsweise im Maschinen und Werkzeugbau) eingesetzt werden kann.Furthermore, a transponder had to be created that could also be used in harsh conditions (for example in machine and tool construction).
Diese Transponder können nicht mehr auf die herkömmliche Weise hergestellt werden, da das Metall den Induktivitätswert der Spule in unbekanntem Maße verändert und somit die Resonanzfrequenz des Transponders verstimmt.These transponders can no longer be manufactured in the conventional way because the metal changes the inductance value of the coil to an unknown extent and thus detunes the resonance frequency of the transponder.
2.4. Lösung 2.4. Solution
Das Problem wird mit der Konstruktion aus Schutzanspruch 1.1. bis 1.5 gelöst.The problem is solved with the construction of claims 1.1 to 1.5.
Hierbei handelt es sich um einen Transponder, bei welchem die Spule durch einen speziellen Ferritkern von der metallischen Umgebung abgeschirmt wird.This is a transponder in which the coil is shielded from the metallic environment by a special ferrite core.

2.5. Erreichte Vorteile2.5. Benefits achieved
Der Ferritkern richtet durch seine spezielle Form (siehe Zeichnung Topfkern) das Magnetfeld des Transponders in eine bestimmte Richtung (Vorderseite offen) und schirmt gleichzeitig die gegenüberliegende Seite ab.Due to its special shape (see drawing of pot core), the ferrite core directs the magnetic field of the transponder in a specific direction (front side open) and at the same time shields the opposite side.
Der Ferritkern bestimmt maßgeblich die Induktivität der Spule und somit die Resonanzfrequenz des Transponders.The ferrite core largely determines the inductance of the coil and thus the resonance frequency of the transponder.
Der Transponder wird dann lagerichtig in ein Metallgehäuse eingeklebt undThe transponder is then glued into a metal housing in the correct position and
vergossen.shed.
Die Vergussmasse dient gleichzeitig als Orientierung der Transponderrichtung.The potting compound also serves as an orientation for the transponder direction.
2.6. Weitere Ausgestaltung2.6. Further development
Die Vorteile der o.g. Konstruktion ergeben sich aus den hervorragenden Eigenschaften der Transponder in Bezug auf die Lesbarkeit in metallischen Gegenständen wie Hochregale aber auch in Maschinen und Anlagen.The advantages of the above-mentioned design arise from the excellent properties of the transponders in terms of readability in metallic objects such as high shelves but also in machines and systems.
Gepaart mit der mechanischen und thermischen Belastbarkeit durch den Einbau ein Metall oder Kunststoffgehäuse konnte ein Bauteil erstellt werden, welches in einer Vielzahl von Einsatzgebieten Anwendung finden kann, wie z.B. bei statistischer Prozesskontrolle an Maschinen usw.Coupled with the mechanical and thermal resilience provided by the installation of a metal or plastic housing, a component was created that can be used in a wide range of applications, such as statistical process control on machines, etc.
Weiterhin ist der Transponder durch die hohe thermische Belastbarkeit in Anlagen einsetzbar, bei denen ein herkömmlicher Transponder nicht die nötige Zuverlässigkeit bietet. Das Metallgehäuse trägt ein übriges zum mechanischen Schutz des Transponders bei.Furthermore, the transponder's high thermal resilience means it can be used in systems where a conventional transponder does not offer the necessary reliability. The metal housing also contributes to the mechanical protection of the transponder.
Die o.g. Transponder sind in der Bauweise als Schrauben (siehe Zeichnung: Transponderschraube MIO) ausführbar und somit sehrThe above-mentioned transponders can be designed as screws (see drawing: Transponder screw MIO) and are therefore very
leicht montierbareasy to assemble
