Description

RADIO-ETIQUETTE DE TYPE RFID POURVUE D'UN ORIFICE TRAVERSANT  RADIO-LABEL OF RFID TYPE PROVIDED WITH A CROSSING ORIFICE
La présente invention concerne une radio-étiquette de type RFID pourvue d'un orifice traversant. Par le terme RFID, de l'anglais radio frequency identification, on désigne tout type de radio-identification, H s'agit d'une méthode pour mémoriser et récupérer des données à distance, par une liaison radio en utilisant des dispositifs appelés « radio-étiquettes » (« RFID tag » ou « RFID transponder » en anglais). Les radio-étiquettes sont de petits objets, tels que des étiquettes autoadhésives, qui peuvent être collés ou incorporés dans des objets ou produits, voire même implantés dans des organismes vivants, par exemple dans le cadre du suivi et/ou de l'identification animale. Les radio-étiquettes comprennent une antenne associée à une puce électronique qui leur permet de recevoir et de répondre aux requêtes radio émises depuis un émetteur-récepteur. Ces puces électroniques contiennent un identifiant et, éventuellement, des données complémentaires, par exemple relatives à l'objet ou à l'organisme vivant sur lequel elles sont fixées. The present invention relates to an RFID type radio-tag having a through hole. By the term RFID, English is defined as any type of radio-identification, it is a method for remotely storing and retrieving data, over a radio link using devices called "radio" tags "(" RFID tag "or" RFID transponder "). Radio tags are small objects, such as self-adhesive labels, which can be glued or incorporated in objects or products, or even implanted in living organisms, for example in the context of animal tracking and / or identification. . The radio tags include an antenna associated with an electronic chip that allows them to receive and respond to radio requests sent from a transceiver. These electronic chips contain an identifier and possibly additional data, for example relating to the object or the living organism to which they are attached.
La communication en champ proche (NFC, selon l'expression en anglais : Near Field Communication) est un type particulier de radio identification basée sur une communication radio à courte portée et à haute fréquence, permettant l'échange d'informations entre des périphériques jusqu'à une distance d'environ 10 cm dans le cas générai. Cette technologie offre l'avantage, à la différence des radio-étiquettes RFID, de pouvoir sécuriser les échanges d'information entre le lecteur, par exemple un smartphone, et la radio-étiquette NFC. Par ailleurs, l'administrateur de la radio-étiquette NFC peut gérer l'accès et/ou les informations contenues dans la radio-étiquette NFC. Near Field Communication (NFC) is a special type of radio identification based on short-range and high-frequency radio communication, allowing the exchange of information between devices until at a distance of about 10 cm in the general case. This technology offers the advantage, unlike RFID RFID tags, of being able to secure the exchange of information between the reader, for example a smartphone, and the NFC radio-tag. In addition, the administrator of the NFC tag can manage the access and / or the information contained in the NFC tag.
II est donc important de pouvoir solidariser la radio-étiquette NFC sur un support de manière pérenne, fiable et sécurisée. Ainsi, on connaît par US-A-2009/021377 une étiquette comportant une puce électronique. Cette étiquette comprend également une antenne et elle est montée sur un DVD ou un CD, autour de l'orifice central. Si on fixe sur un support des radio -étiquettes adhésives inarrachabies et indéchirables, il arrive également que la radio -étiquette NFC soit noyée dans le matériau constitutif du support. Or, avec certains supports et/ou procédés de fixation de la radio-étiquette NFC, certains problèmes peuvent apparaître. It is therefore important to be able to secure the NFC tag on a support in a durable, reliable and secure manner. Thus, US-A-2009/021377 discloses a label comprising an electronic chip. This tag also includes an antenna and is mounted on a DVD or CD, around the center hole. If we fix on a support radio-labels adhesive inarrachabie and tear-proof, it arrives also that the radio-tag NFC is embedded in the material constituting the support. However, with certain supports and / or methods for fixing the NFC radio-tag, certain problems may appear.
Il en est ainsi avec un disque vinyle utilisé comme support. Lorsque Ton souhaite fixer de manière sécurisée et pérenne une radio-étiquette NFC sur un disque vinyle, on incorpore cette dernière au matériau constitutif du disque, lors d'une opération de pressage à chaud connue en soi et qui a pour objet de graver des sillons, correspondant aux vibrations acoustiques, sur le disque vinyle. Lors de cette opération, la radio- étiquette NFC doit être située dans une zone plane, non gravée pour ne pas nuire à la lecture de sillons et donc à la restitution sonore. En d'autres termes, seule la région voisine de l'orifice central qui reçoit l'arbre de rotation du disque vinyle est utilisable. Par ailleurs, il est souhaitable que les conditions de fixation de la radio-étiquette sur le support, en particulier en termes de pression et température, n'affectent pas, ou à minima, l'étiquette.  This is so with a vinyl record used as a medium. When it is desired to securely and permanently fix an NFC radio-label on a vinyl disc, the latter is incorporated in the material constituting the disc, during a heat-pressing operation known per se and whose purpose is to engrave grooves. , corresponding to acoustic vibrations, on the vinyl record. During this operation, the NFC radio-label must be located in a flat zone, not engraved so as not to interfere with the reading of grooves and thus the sound reproduction. In other words, only the region adjacent to the central orifice which receives the rotation shaft of the vinyl disc is usable. Furthermore, it is desirable that the conditions for fixing the radio-tag on the support, in particular in terms of pressure and temperature, do not affect, or at least the label.
La demanderesse a constaté que l'emploi d'une radio-étiquette NFC telle que disponible dans le commerce ne convient pas. En effet, cette dernière, lors de l'opération de pressage du disque, a tendance, sous l'action combinée de la chaleur et de la pression, à se déplacer. La radio-étiquette NFC se retrouve alors soit sur un sillon soit en porte-à faux sur l'orifice central.  The Applicant has found that the use of a NFC radio-tag as commercially available is not suitable. Indeed, the latter, during the pressing operation of the disc, tends, under the combined action of heat and pressure, to move. The NFC radio-tag is then found either on a furrow or cantilevered on the central hole.
C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant une radio-étiquette de type RFID aisée à mettre en place dans le matériau constitutif d'un disque vinyle, sans déplacement de celle-ci lors des opérations de pressage, cela quel que soit le type de disque vinyle.  It is these drawbacks that the invention more particularly intends to remedy by proposing an RFID-type radio-tag that is easy to put into place in the constituent material of a vinyl disc, without moving it during pressing operations. , regardless of the type of vinyl record.
A cet effet, l'invention a pour objet une radio-étiquette de type RFID pour disque vinyle comportant au moins une puce électronique et une antenne, configurée en spirale et dont la partie centrale de la radio-étiquette est pourvue d'un orifice traversant, caractérisée en ce que la radio-étiquette est de sous-type NFC et en ce que l'antenne forme une spirale circulaire dont le centre géométrique est confondu avec le centre géométrique par lequel passe l'axe de rotation d'un disque vinyle sur lequel est fixée la radio-étiquette et en ce que la radio-étiquette comprend une zone située entre son centre géométrique et la spire la plus proche est pleine dépourvue d'équipement. For this purpose, the subject of the invention is an RFID-type radio-label for a vinyl disk comprising at least one electronic chip and an antenna, configured in a spiral and whose central part of the radio-tag is provided with a through-orifice. , characterized in that the radio-tag is of NFC subtype and in that the antenna forms a circular spiral whose geometric center coincides with the geometric center through which the axis of rotation of a vinyl disk passes over which is fixed radio-label and in that the radio-tag comprises an area between its geometric center and the nearest turn is full without equipment.
Avec une telle configuration, la radio-étiquette est, une fois fixée, positionnée autour de l'orifice central du disque vinyle avec son antenne régulièrement répartie autour de l'orifice central du disque. Lors des opérations de pressage à chaud, la demanderesse a constaté qu'une telle configuration évite ou du moins limite tout déplacement de la radio-étiquette. L'antenne configurée en spirale permet une répartition homogène des forces selon toutes les directions. On annule de la sorte l'effet de ces forces et la radio-étiquette a, si ce n'est un déplacement nul, au moins un déplacement extrêmement limité.  With such a configuration, the radio-tag is, once fixed, positioned around the central orifice of the vinyl disk with its antenna evenly distributed around the central orifice of the disk. During hot pressing operations, the Applicant has found that such a configuration avoids or at least limits any movement of the radio-tag. The spiral antenna provides a uniform distribution of forces in all directions. In this way, the effect of these forces is canceled and the radio-tag has, if not a zero displacement, at least one extremely limited displacement.
Selon des aspects avantageux mais non obligatoires de l'invention, une telle radio-étiquette peut comprendre une ou plusieurs des caractéristiques suivantes:  According to advantageous but non-compulsory aspects of the invention, such a radio-tag may comprise one or more of the following characteristics:
- l'antenne comprend entre quatre et quinze spires.  the antenna comprises between four and fifteen turns.
- L'orifice traversant de la partie centrale de la radio-étiquette est circulaire.  - The through hole of the central part of the radio-tag is circular.
- Le diamètre de l'orifice traversant la partie centrale de la radio-étiquette est au moins égal au diamètre de l'orifice central du disque vinyle. - The diameter of the orifice passing through the central part of the radio-label is at least equal to the diameter of the central orifice of the vinyl disc.
L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lecture de la description qui va suivre de plusieurs modes de réalisation de l'invention, donnée à titre d'exemple non limitatif et faite en référence au dessin suivant dans lequel:  The invention will be better understood and other advantages thereof will appear more clearly on reading the following description of several embodiments of the invention, given by way of non-limiting example and made with reference to FIG. following drawing in which:
- La figure 1 est une vue de dessus, schématique et simplifiée, d'une radio-étiquette conforme à un mode de réalisation de l'invention.  - Figure 1 is a top view, schematic and simplified, a radio-label according to one embodiment of the invention.
La figure 1 illustre, de manière schématique, une radio-étiquette 1 destinée à être incorporée, par une opération de pressage à chaud connue en soi, à la matière constitutive d'un disque vinyle. Pour mémoire, de tels disques sont de diamètres externes différents, selon le nombre de sillons gravés sur le disque, donc selon le nombre de fichiers sonores gravés sur le disque. Plus le diamètre externe du disque vinyle est important et plus, potentiellement, le nombre de fichiers sonores est susceptibles d'être important, donc de facto la durée d'écoute. On classe les disques vinyles en fonction de leurs vitesses de lecture, cette dernière étant en relation directe avec leur diamètre. Il y a des 45 tours/min, des 33 tours/min et des 78 tours /min. Outre des vitesses de lecture différentes, ces disques ont un orifice central assurant le passage de l'arbre de rotation du lecteur d'un diamètre diffèrent. L'invention permet d'équiper ces divers types de disque vinyle avec une radio-étiquette. Figure 1 schematically illustrates a radio tag 1 to be incorporated, by a hot pressing operation known per se, to the constituent material of a vinyl disc. For the record, such discs have different external diameters, depending on the number of grooves engraved on the disc, so depending on the number of sound files burned on the disc. The larger the outer diameter of the vinyl record is, and the more potentially the number of sound files is likely to be important, so de facto the listening time. Vinyl records are classified according to their reading speeds, the latter being in direct relationship with their diameter. There are 45 rpm, 33 rpm and 78 rpm. In addition to different reading speeds, these discs have a central hole ensuring the passage of the drive rotation shaft of a different diameter. The invention makes it possible to equip these various types of vinyl record with a radio-tag.
Par la suite, pour faciliter la lecture, le terme étiquette sera seul utilisé, étant entendu qu'ici ce terme désigne autant une radio-étiquette RFID que, plus particulièrement, une radio-étiquette NFC.  Subsequently, for ease of reading, the term label will only be used, it being understood that here this term refers to both an RFID radio-tag and, more particularly, an NFC radio-tag.
A la figure 1 , l'étiquette 1 est illustrée avec une forme externe circulaire de diamètre E. En variante, la forme externe est différente, par exemple carrée, rectangulaire, ovale ou triangulaire. Dans tous les cas, l'encombrement maximal de l'étiquette, donc ici le diamètre E, est tel que l'étiquette, fixée sur un disque vinyle, est entièrement comprise dans la zone dépourvue de sillons d'un disque vinyle, quel que soit le type de ce dernier. Selon l'invention, par fixation de l'étiquette sur le disque vinyle, on désigne le fait d'incorporer dans le matériau constitutif du disque l'étiquette, de sorte qu'il n'y a pas de surépaisseur du disque due à l'étiquette, celle-ci étant par ailleurs inarrachable.  In FIG. 1, the label 1 is illustrated with a circular external shape of diameter E. As a variant, the external shape is different, for example square, rectangular, oval or triangular. In all cases, the maximum size of the label, so here the diameter E, is such that the label, fixed on a vinyl record, is entirely included in the area devoid of furrows of a vinyl record, whatever the type of the latter. According to the invention, by fixing the label on the vinyl disc, it is meant to incorporate in the constituent material of the disc the label, so that there is no extra thickness of the disc due to the label, which is otherwise unobtrusive.
L'étiquette 1 comprend une puce électronique 2 reliée par soudure conductrice aux extrémités 3, 4 d'une antenne filaire continue 5. Une zone 20 forme un pont non conducteur permettant de passer par-dessus l'antenne et de relier la puce 3 à une extrémité 3 de l'antenne 5. L'antenne 5 est configurée en spirale circulaire. Le nombre de spires est au moins de quatre généralement compris entre quatre et douze, avec un maximum de quinze. Le nombre de spires est adapté afin de permettre la lecture des informations présentes sur l'étiquette, selon l'épaisseur de l'emballage du produit sur lequel est fixée l'étiquette. L'écartement entre deux spires voisines est compris entre 0,5 mm et 1 mm, étant entendu que le fil constitutif de l'antenne a une section voisine de 0,5 mm. Comme cela ressort de la figure 1 , la zone située entre le centre géométrique 6 de la spirale et la spire 7 la plus proche est divisée en deux zones 8, 9 concentriques. The tag 1 comprises an electronic chip 2 connected by conductive soldering to the ends 3, 4 of a continuous wire antenna 5. A zone 20 forms a non-conductive bridge making it possible to pass over the antenna and to connect the chip 3 to one end 3 of the antenna 5. The antenna 5 is configured in a circular spiral. The number of turns is at least four generally between four and twelve, with a maximum of fifteen. The number of turns is adapted to allow the reading of the information present on the label, according to the thickness of the packaging of the product on which the label is attached. The spacing between two adjacent turns is between 0.5 mm and 1 mm, it being understood that the constituent wire of the antenna has a section close to 0.5 mm. As is apparent from Figure 1, the area between the geometric center 6 of the spiral and the nearest turn 7 is divided into two concentric zones 8, 9.
La zone 8, à savoir la plus proche de la spire 7, est pleine et dépourvue de tout équipement. En variante, elle peut comporter un marquage visuel. Dans un autre mode de réalisation, des orifices traversant sont ménagés dans cette zone 8.  Zone 8, which is the closest to turn 7, is full and devoid of any equipment. Alternatively, it may include a visual marking. In another embodiment, through openings are formed in this zone 8.
La zone 9, située autour du centre géométrique 6, est évidée et forme un orifice traversant circulaire. Le diamètre D de la zone 9 est compris entre 7 mm et 40 mm, étant entendu qu'un diamètre D voisin de 7 mm correspond au diamètre central d'un disque vinyle 33 tours. Un tel diamètre D est adapté au diamètre de l'orifice central des disques vinyle, que ce soit un 33 tours, un 45 tours ou un 78 tours. Selon un mode de réalisation, Chaque disque, que ce soit un 33 tours, un 45 tours ou un 78 tours, reçoit une étiquette dont le diamètre D de la zone 9 est adapté à l'arbre de rotation du disque, donc à son orifice central. Selon un autre mode de réalisation, Le diamètre D de la zone centrale 9 d'une étiquette correspond au diamètre maximal rencontré. Une telle étiquette peut donc équiper tout type de disque vinyle, quel que soit le diamètre de son arbre de rotation donc de son orifice.  Zone 9, located around the geometric center 6, is recessed and forms a circular through hole. The diameter D of the zone 9 is between 7 mm and 40 mm, it being understood that a diameter D close to 7 mm corresponds to the central diameter of a vinyl record 33 turns. Such a diameter D is adapted to the diameter of the central orifice of the vinyl records, be it a 33 rpm, a 45 rpm or a 78 rpm. According to one embodiment, each disc, be it a 33 rpm, a 45 rpm or a 78 rpm, receives a label whose diameter D of the zone 9 is adapted to the rotation shaft of the disc, therefore to its orifice central. According to another embodiment, the diameter D of the central zone 9 of a label corresponds to the maximum diameter encountered. Such a label can therefore equip any type of vinyl record, regardless of the diameter of its rotation shaft and its orifice.
Ainsi, lorsque l'étiquette 1 est en position sur un disque de vinyle, le centre géométrique 6 de l'antenne 5 configurée en spirale est confondu avec le centre géométrique du disque vinyle par lequel passe son axe de rotation. La zone 9 a un diamètre tel qu'en aucun cas elle ne peut être obturée, même partiellement, par une partie du disque vinyle lorsque l'étiquette est en place sur celui-ci. En d'autres termes, le diamètre D de la zone 9 est suffisant pour que la zone 8 n'empiète jamais sur la partie évidée du disque. L'antenne 5 est donc toujours positionnée en spirale autour de l'orifice central du disque vinyle lorsque l'étiquette 1 est en place sur le disque.  Thus, when the label 1 is in position on a vinyl disc, the geometric center 6 of the antenna 5 configured in a spiral coincides with the geometric center of the vinyl disc through which its axis of rotation passes. The zone 9 has a diameter such that in no case it can be closed, even partially, by a portion of the vinyl disc when the label is in place thereon. In other words, the diameter D of the zone 9 is sufficient so that the zone 8 never encroaches on the recessed part of the disk. The antenna 5 is therefore always positioned spirally around the central orifice of the vinyl disc when the label 1 is in place on the disc.
La demanderesse a constaté de manière surprenante qu'une telle configuration en spirale permet, lorsque l'on incorpore une telle étiquette 1 dans un disque vinyle, de sorte que l'étiquette soit intégrée dans le matériau constitutif du disque vinyle, par l'opération connue de pressage à chaud au cours de laquelle on grave les sillons, de conserver le positionnement initial de l'étiquette 1 , sans déplacement de cette dernière. En effet, le pressage a tendance à générer un écrasement de la matière avec un effet centrifuge induisant un déplacement de la matière en direction de la périphérie du disque. Une configuration en spirale de l'antenne permet d'une part de répartir régulièrement la pression sur toute l'antenne et, d'autre part, de contre balancer l'effet centrifuge. Celui-ci a tendance, au pire, à rapprocher les spires mais cela sans modifier significativement le diamètre externe de l'antenne 5. Celle-ci est par ailleurs centrée sur le centre de rotation du disque, il ne peut donc y avoir de déformation ou de déplacement significatif de l'antenne 5 susceptible d'endommager ou d'affecter le fonctionnement de l'étiquette 1 . Cette dernière est ainsi fixée de manière pérenne dans le matériau constitutif du disque vinyle, sans possibilité d'arrachage et sans que les dimensions nominales du disque soient modifiées. The applicant has found, surprisingly, that such a spiral configuration makes it possible, when incorporating such a label 1 into a vinyl disc, so that the label is integrated into the constituent material of the vinyl disc, by the operation known hot pressing during which is engraved grooves, to maintain the initial positioning of the label 1, without displacement of the latter. Indeed, the pressing tends to generate a crushing of the material with a centrifugal effect inducing a movement of the material towards the periphery of the disc. A spiral configuration of the antenna allows on the one hand to regularly distribute the pressure on the entire antenna and, on the other hand, to counterbalance the centrifugal effect. It tends, at worst, to bring the turns but without significantly changing the outer diameter of the antenna 5. It is also centered on the center of rotation of the disc, so there can be deformation or significant displacement of the antenna 5 may damage or affect the operation of the tag 1. The latter is thus permanently fixed in the material constituting the vinyl disc, without the possibility of tearing and without the nominal dimensions of the disc are modified.
Pour effectuer un tel présage à chaud, l'antenne (5) est dans un premier temps, imprimée par sérigraphie, ou en variante par flexographie, sur un papier dédié, adapté pour permettre l'impression directe de circuits électroniques. Il s'agit, par exemple, du papier commercialisé sous l'appellation POWERCOAT par la société ARJOWIGGINS.  To carry out such a hot premix, the antenna (5) is initially printed by screen printing, or alternatively by flexography, on a dedicated paper adapted to allow the direct printing of electronic circuits. This is, for example, the paper sold under the name POWERCOAT by the company ARJOWIGGINS.
La fixation de la puce électronique est effectuée sur le papier pourvu de l'antenne imprimée avec une colle connue en soi et adaptée pour résister aux conditions du pressage, notamment en termes de température et de pression. En l'espèce, la colle et le papier utilisés permettent de supporter des pressions allant jusqu'à 50 bars et des températures voisines de 180°C.  The attachment of the electronic chip is performed on the paper provided with the antenna printed with an adhesive known per se and adapted to withstand the conditions of pressing, especially in terms of temperature and pressure. In this case, the glue and paper used can withstand pressures up to 50 bar and temperatures close to 180 ° C.
L'étiquette ainsi réalisée est alors pressée dans le vinyle en même temps que les sillons sont gravés, lors de l'étape connue sous l'expression de pressage à chaud. On obtient alors un disque vinyle équipé d'une étiquette noyée dans le matériau vinylique.  The label thus produced is then pressed into the vinyl at the same time as the grooves are etched, during the step known as hot pressing. This produces a vinyl disc equipped with a label embedded in the vinyl material.
