DISPOSITIF D'ASSEMBLAGE AVEC SYSTEME DE CONTROLE DE L'ASSEMBLAGEASSEMBLY DEVICE WITH ASSEMBLY CONTROL SYSTEM
Domaine technique de l'inventionTechnical field of the invention
L'invention concerne un dispositif d'assemblage de deux éléments de construction, ledit dispositif d'assemblage étant équipé d'un système de contrôle de l'assemblage comportant un capteur de mesure d'un paramètre physique de contrôle de l'assemblage et une étiquette radiofréquence communiquant avec ledit capteur de mesure.The invention relates to a device for assembling two construction elements, said assembly device being equipped with an assembly control system comprising a sensor for measuring a physical parameter for controlling the assembly and a device for controlling the assembly. radiofrequency label communicating with said measurement sensor.
État de la techniqueState of the art
Les capteurs de mesure utilisés, à l'heure actuelle, dans les systèmes de contrôle intégrés aux dispositifs d'assemblage, fonctionnent selon un principe binaire, c'est-à-dire du type tout ou rien. Ces systèmes de contrôle permettent de statuer, à distance, sur l'état activé ou non du capteur de mesure.The measurement sensors currently used in control systems integrated with the assembly devices operate according to a binary principle, that is to say, of the all-or-nothing type. These control systems make it possible to remotely decide on the activated or non-activated state of the measurement sensor.
En fonction de l'agencement du dispositif lui-même et du fonctionnement du système de contrôle intégré, l'état du capteur ne permet parfois pas de statuer avec certitude sur l'état assemblé ou non du dispositif d'assemblage. Ainsi, avec beaucoup de dispositifs d'assemblage connus, il est possible que le capteur de mesure change d'état bien que le dispositif ne soit pas à l'état assemblé.Depending on the arrangement of the device itself and the operation of the integrated control system, the state of the sensor sometimes does not make it possible to decide with certainty on the assembled state or not of the assembly device. Thus, with many known assembly devices, it is possible that the measuring sensor changes state although the device is not in the assembled state.
D'autre part, de tels capteurs de mesure ne permettent pas de contrôler qualitativement l'assemblage réalisé. Dans beaucoup d'applications connues, il est possible que l'assemblage soit mal réalisé (par exemple à cause de conditions de montage non respectées), sans que le système de contrôle ne puisse le détecter. En effet, dans ce cas, le capteur de mesure change d'état lors de l'assemblage, et le système de contrôle permet de constater que l'assemblage a été réalisé. Mais un risque subsiste que le dispositif se détériore ensuite dans le temps, voire se désassemble, à cause des mauvaises conditions de montage.On the other hand, such measuring sensors do not allow to qualitatively control the assembly made. In many known applications, it is possible that the assembly is poorly made (for example because of assembly conditions not respected), without the system of control can not detect it. Indeed, in this case, the measuring sensor changes state during assembly, and the control system allows to note that the assembly was made. But a risk remains that the device then deteriorates over time, or even disassembles, because of poor mounting conditions.
Objet de l'inventionObject of the invention
L'invention a pour but d'améliorer le contrôle de l'assemblage des dispositifs d'assemblage de deux éléments de construction.The object of the invention is to improve the control of the assembly of the assembly devices of two construction elements.
Selon l'invention, ce but est atteint par le fait que le système de contrôle est apte à déterminer une courbe caractéristique représentative de l'évolution du paramètre physique de contrôle lors de l'assemblage des deux éléments de construction, et en ce que l'étiquette radiofréquence est apte à transmettre un signal de contrôle représentatif de ladite courbe caractéristique jusqu'à une unité de contrôle extérieure pour comparaison avec une courbe spécifique prédéterminée.According to the invention, this object is achieved by the fact that the control system is able to determine a characteristic curve representative of the evolution of the physical control parameter during the assembly of the two construction elements, and that the The radiofrequency tag is adapted to transmit a control signal representative of said characteristic curve to an external control unit for comparison with a predetermined specific curve.
La courbe spécifique prédéterminée enregistrée dans l'unité de contrôle est établie pour des conditions d'assemblage correspondant à un assemblage normal satisfaisant à toutes les exigences attendues. Un système de contrôle conforme à l'invention permet donc, lorsque la comparaison est positive entre la courbe spécifique prédéterminée et la courbe caractéristique reçue, de conclure avec certitude que le dispositif est à l'état assemblé, et que l'assemblage a été qualitativement bien réalisé.The predetermined specific curve recorded in the control unit is established for assembly conditions corresponding to a normal assembly satisfying all the expected requirements. A control system according to the invention therefore makes it possible, when the comparison is positive between the predetermined specific curve and the characteristic curve received, to conclude with certainty that the device is in the assembled state, and that the assembly has been qualitatively well done.

Description de modes particuliers de réalisationDescription of particular embodiments
Les figures 1 à 3 illustrent un premier mode de réalisation de dispositif d'assemblage selon l'invention. Le dispositif d'assemblage, repéré 10, est de forme allongée et destiné à l'assemblage d'un tube sur un support (non représentés), avec une partie supérieure 11 pour l'emboîtement du tube, et une partie inférieure 12 pour la fixation du dispositif d'assemblage 10 sur le support. Dans la variante représentée, les parties supérieure et inférieure 11 et 12 sont constituées par deux ensembles monoblocs en matière plastique, rendus solidaires l'un à l'autre dans la zone centrale du dispositif d'assemblage 10.Figures 1 to 3 illustrate a first embodiment of assembly device according to the invention. The assembly device, marked 10, is of elongated shape and intended for assembling a tube on a support (not shown), with an upper part 11 for the interlocking of the tube, and a lower part 12 for the fixing the assembly device 10 on the support. In the variant shown, the upper and lower parts 11 and 12 consist of two monoblock assemblies of plastic material, secured to one another in the central zone of the assembly device 10.
La zone centrale du dispositif d'assemblage 10 forme un carter 13 rectangulaire, d'épaisseur faible, pour le logement d'une étiquette radiofréquβnce 14 de forme annulaire. Le carter 13 est composé d'un couvercle 15, de forme rectangulaire, appartenant à la partie supérieure 11, et d'une plaque 16, de forme complémentaire du couvercle 15, appartenant à la partie inférieure 12.The central zone of the assembly device 10 forms a rectangular casing 13, of small thickness, for housing a radiofrequency tag 14 of annular shape. The housing 13 is composed of a lid 15, of rectangular shape, belonging to the upper part 11, and a plate 16, of complementary shape of the lid 15, belonging to the lower part 12.
Depuis la face extérieure du couvercle 15 s'étend un élément de maintien 17 d'une bague de clipage 18 du tube. La bague de clipage 18 est en forme de « C » dόformable dont l'ouverture est dirigée vers le haut. L'élément de maintien 17 présente une section en forme de croisillon pour une bonne rigidité. Les extrémités de la bague de clipage 18 supportent des ailettes de guidage 19, convergentes, facilitant la mise en place du tube dans la bague de clipage 18 lors de l'emboîtement.From the outer face of the cover 15 extends a holding member 17 of a clipping ring 18 of the tube. The clipping ring 18 is shaped "C" deformable whose opening is directed upwards. The holding member 17 has a cross-shaped section for good rigidity. The ends of the clipping ring 18 support guide vanes 19, converging, facilitating the introduction of the tube in the clipping ring 18 during the nesting.
Depuis la face extérieure de la plaque 16 s'étend un voile de support 20 de deux ergots flexibles 21 assurant la fixation de la partie inférieure 12 sur le support. Les ergots flexibles 21 s'étendent depuis l'extrémité distale du voile de support 20 en direction de la plaque 16. Lors de l'insertion du voile de support 20 dans un trou correspondant pratiqué dans le support, les ergots flexibles 21 se rabattent progressivement contre le voile de support 20. Lorsque les ergots flexibles 21 sont libérés, ceux-ci reviennent dans leur configuration initiale par retour élastique, réalisant ainsi la retenue longitudinale du support entre les ergots flexibles 21 et la plaque 16.From the outer face of the plate 16 extends a support web 20 of two flexible lugs 21 for fixing the lower portion 12 on the support. The flexible lugs 21 extend from the distal end of the support veil 20 in the direction of the plate 16. During the insertion of the support veil 20 into a corresponding hole made in the support, the flexible lugs 21 are progressively folded down. against the support web 20. When the flexible lugs 21 are released, they return to their initial configuration by springback, thus achieving the longitudinal retention of the support between the flexible lugs 21 and the plate 16.
La fixation de la plaque 16 dans le couvercle 15 est réalisée par tout moyen approprié, par exemple par collage, par soudage, ou par clipage. Dans d'autres variantes, la partie inférieure 12 est surmoulée sur le couvercle 15. Un centreur 22, de forme cylindrique, est agencé à l'intérieur du couvercle 15 pour assurer le maintien transversal de l'étiquette radie-fréquence 14. Cette dernière est mise en place dans le couvercle 15 avant la fixation de la partie inférieure 12. De manière complémentaire, et en référence à la figure 3, la plaque 16 comporte un évidement principal 23, de forme cylindrique, pour le logement de l'étiquette radie-fréquence 14. Dans le fond de l'évidement principal 23 est agencé coaxialement un évidement secondaire 24 pour la réception du centreur 22 pendant la fixation des parties supérieure et inférieure 11 et 12 par mise en place de la plaque 16 dans le couvercle 15.Fixing the plate 16 in the lid 15 is carried out by any appropriate means, for example by gluing, welding, or clipping. In other variants, the lower portion 12 is overmolded on the cover 15. A centralizer 22, of cylindrical shape, is arranged inside the cover 15 to ensure the transverse retention of the radie-frequency tag 14. The latter is placed in the cover 15 before fixing the lower part 12. In a complementary manner, and with reference to Figure 3, the plate 16 has a main recess 23, of cylindrical shape, for the housing of the radie label -frequency 14. In the bottom of the main recess 23 is arranged coaxially a secondary recess 24 for the receiving the centering device 22 during fixing of the upper and lower parts 11 and 12 by placing the plate 16 in the cover 15.
Un avidement supplémentaire 25 est pratiqué dans l'un des angles de la plaque 16, en périphérie de l'évidement principal 23. L'όvidβment supplémentaire 25 permet de loger un capteur d'accélération (non représenté sur la figure 3) dont la fonction sera détaillée plus loin. Le capteur d'accélération et l'étiquette radiofréquence 14 sont donc intégrés au dispositif d'assemblage 10.Additional avidement is performed in one of the corners of the plate 16, at the periphery of the main recess 23. The additional element 25 accommodates an acceleration sensor (not shown in FIG. 3) whose function will be detailed later. The acceleration sensor and the radiofrequency label 14 are therefore integrated in the assembly device 10.
Comme représenté schématiquement à la figure 4, le capteur d'accélération, qui est repéré 26 sur cette figure et qui est destiné, en pratique, à être logé dans l'évidement supplémentaire 25, est relié à l'étiquette radiofréquence 14 qui est, par exemple, du type passif. L'étiquette radiofréquence 14 comporte une antenne 27 accordée sur une fréquence prédéterminée et connectée à une puce 28 qui contient un code d'identification individuel ID. Le capteur d'accélération 26 est connecté à un microprocesseur 29 de la puce 28. La puce 28 comporte, en outre, une mémoire 30 reliée au microprocesseur 29. Le capteur d'accélération 26 associé à l'étiquette radiofréquence 14 constitue un système de contrôle CR intégré au dispositif d'assemblage 10.As shown diagrammatically in FIG. 4, the acceleration sensor, which is marked 26 in this figure and which is intended, in practice, to be housed in the additional recess 25, is connected to the radiofrequency tag 14 which is for example, of the passive type. The radiofrequency tag 14 includes an antenna 27 tuned to a predetermined frequency and connected to a chip 28 which contains an individual ID code ID. The acceleration sensor 26 is connected to a microprocessor 29 of the chip 28. The chip 28 furthermore comprises a memory 30 connected to the microprocessor 29. The acceleration sensor 26 associated with the radiofrequency tag 14 constitutes a memory system. CR control integrated into the assembly device 10.
De manière connue, un signal de porteuse P reçu par l'antenne 27 de l'étiquette radiofréquence 14 sert généralement simultanément de signal d'interrogation et d'alimentation en énergie de l'étiquette radiofréquence 14. Celle-ci renvoie alors un signal de porteuse désigné ci-après signal de contrôle SC, modulé par exemple en amplitude par son code ID.In a known manner, a carrier signal P received by the antenna 27 of the radiofrequency tag 14 generally serves simultaneously as an interrogation and power supply signal for the radiofrequency tag 14. This then sends a signal of carrier designated hereinafter control signal SC, modulated for example in amplitude by its ID code.
Le signal de porteuse P est émis par une unité de contrôle 31 extérieure au système de contrôle CR, et située à distance du dispositif d'assemblage 10. Dans la variante de réalisation décrite, pour pouvoir communiquer par radiofréquence avec l'étiquette radiofréquence 14 solidaire du dispositif d'assemblage 10, l'unité de contrôle 31 comporte une unité de traitement βThe carrier signal P is emitted by a control unit 31 external to the control system CR, and located at a distance from the assembly device 10. In the variant embodiment described, in order to be able to communicate by radio frequency with the radiofrequency tag 14 secured to it of the assembly device 10, the control unit 31 comprises a processing unit β
électronique, de préférence à microprocesseur, connectée à une mémoire, à une antenne par l'intermédiaire d'une interface d'émission-réception, ainsi qu'à une interface homme-machine. L'interface homme-machine de l'unité de contrôle 31 peut comporter un clavier, un écran de visualisation et/ou un haut-parleur. Le signal de contrôle SC émis par l'antenne 27 de l'étiquette radiofréquence 14, est adapté pour être reçu par l'antenne de l'unité de contrôle 31.electronic, preferably microprocessor, connected to a memory, to an antenna via a transceiver interface, and to a man-machine interface. The human-machine interface of the control unit 31 may comprise a keyboard, a display screen and / or a loudspeaker. The control signal SC transmitted by the antenna 27 of the radiofrequency tag 14 is adapted to be received by the antenna of the control unit 31.
En pratique, l'assemblage du tube sur le support grâce au dispositif d'assemblage 10 est généralement pratiqué dans une zone où la communication entre l'étiquette radiofréquβnce 14 et l'unité de contrôle 31 est possible. Grâce au signal de porteuse P1 l'étiquette radiofréquence 14 et le capteur d'accélération 26 sont alimentés en énergie. Lors de l'assemblage du tube ou du support respectivement sur les parties supérieure 11 et inférieure 12 du dispositif d'assemblage 10, le capteur d'accélération 26 mesure les vibrations internes du dispositif d'assemblage 10. Le capteur d'accélération 26 transmet, lors de l'assemblage, un signal de mesure SM au microprocesseur 29. Ce dernier génère, en temps réel, à partir du signal de mesure SM, une courbe caractéristique représentative de l'évolution de l'accélération mesurée par le capteur d'accélération 26 pendant l'assemblage. Le microprocesseur 29 génère ensuite un signal d'excitation SE de l'antenne 27, représentatif de la courbe caractéristique générée. A partir du signal d'excitation SE1 l'antenne 27 de l'étiquette radiofréquence 14 génère un signal de contrôle SC représentatif de la courbe caractéristique générée par le microprocesseur 29. Le signal de contrôle SC est reçu par l'unité de contrôle 31, laquelle peut pratiquer, grâce à son unité de traîtement, une comparaison entre la courbe caractéristique générée par le système de contrôle CR pendant l'assemblage du tube et du support, et une courbe spécifique prédéterminée enregistrée dans la mémoire de l'unité de contrôle 31. La courbe spécifique prédéterminée est préalablement établie pour des conditions d'assemblage correspondant à un assemblage normal satisfaisant à toutes les exigences attendues. Après traitement par le microprocesseur de l'unité de contrôle 31, le résultat de la comparaison est indiqué à l'opérateur grâce à l'interface homme-machine, et/ou enregistré dans la mémoire de l'unité de contrôle 31.In practice, the assembly of the tube on the support by the assembly device 10 is generally practiced in an area where the communication between the radiofrequency label 14 and the control unit 31 is possible. With the carrier signal P 1, the radiofrequency tag 14 and the acceleration sensor 26 are supplied with energy. When assembling the tube or the support respectively on the upper 11 and lower 12 parts of the assembly device 10, the acceleration sensor 26 measures the internal vibrations of the assembly device 10. The acceleration sensor 26 transmits , during assembly, a measurement signal SM to the microprocessor 29. The latter generates, in real time, from the measurement signal SM, a characteristic curve representative of the evolution of the acceleration measured by the sensor. acceleration 26 during assembly. The microprocessor 29 then generates an excitation signal SE of the antenna 27, representative of the generated characteristic curve. From the excitation signal SE 1 the antenna 27 of the radiofrequency tag 14 generates a control signal SC representative of the characteristic curve generated by the microprocessor 29. The control signal SC is received by the control unit 31 which can, by virtue of its processing unit, make a comparison between the characteristic curve generated by the control system CR during assembly of the tube and the support, and a predetermined specific curve recorded in the memory of the control unit 31. The predetermined specific curve is previously established for assembly conditions corresponding to a normal assembly satisfying all the expected requirements. After treatment with microprocessor of the control unit 31, the result of the comparison is indicated to the operator through the human-machine interface, and / or stored in the memory of the control unit 31.
Lorsque le résultat de la comparaison pratiquée par l'unité de traitement de l'unité de contrôle 31 est positif entre la courbe spécifique prédéterminée et la courbe caractéristique reçue, il est possible de conclure avec certitude que le dispositif d'assemblage 10 se trouve dans l'état assemblé, et que l'assemblage a été qualitativement bien réalisé. Au contraire, lorsque ce résultat est négatif, il est possible de conclure que l'assemblage n'a pas été effectué, ou n'a pas été qualitativement bien réalisé bien que le dispositif d'assemblage 10 soit à l'état assemblé, et d'estimer dans ce cas le type de défaut de montage (montage excessif, montage insuffisant...)-When the result of the comparison made by the processing unit of the control unit 31 is positive between the predetermined specific curve and the characteristic curve received, it is possible to conclude with certainty that the assembly device 10 is in the assembled state, and that the assembly was qualitatively well done. On the other hand, when this result is negative, it is possible to conclude that the assembly has not been performed, or has not been performed qualitatively well, even though the assembly device 10 is in the assembled state, and to estimate in this case the type of mounting defect (excessive mounting, insufficient mounting ...) -
En pratique, l'assemblage du tube sur le support grâce au dispositif d'assemblage 10 peut aussi être pratiqué dans une zone où la communication entre l'étiquette radiofréquence 14 et l'unité de contrôle 31 n'est pas prévue. Dans ce cas, le système de contrôle CR comporte une source d'énergie intégrée pour l'alimentation de l'étiquette radiofréquence 14 et du capteur d'accélération 26. Par exemple, la source d'énergie peut être intégrée à l'étiquette radiofréquence 14, laquelle constitue alors un étiquette du type semi-actif. Dans d'autres variantes, la source d'énergie est extérieure à l'étiquette radiofréquence 14, et est fournie à cette dernière, par exemple par l'intermédiaire de l'antenne 27 ou d'une deuxième antenne (non représentée) prévue dans l'étiquette radiofréquence 14 et accordée sur une deuxième fréquence prédéterminée.In practice, the assembly of the tube on the support by the assembly device 10 can also be practiced in an area where the communication between the radiofrequency label 14 and the control unit 31 is not provided. In this case, the control system CR comprises an integrated power source for supplying the radiofrequency label 14 and the acceleration sensor 26. For example, the energy source can be integrated into the radiofrequency label 14, which then constitutes a label of the semi-active type. In other variants, the energy source is external to the radiofrequency tag 14, and is supplied to the latter, for example via the antenna 27 or a second antenna (not shown) provided in FIG. the radiofrequency tag 14 and tuned to a second predetermined frequency.
Dans cette variante, lors de l'assemblage du tube ou du support respectivement sur les parties supérieure 11 et inférieure 12 du dispositif d'assemblage 10, le microprocesseur 29 génère, en temps réel, à partir du signal de mesure SM provenant du capteur d'accélération 26, une courbe caractéristique représentative de l'évolution de l'accélération mesurée. Le microprocesseur 29 génère et transfert ensuite jusqu'à la mémoire 30, des données D représentatives de ladite courbe caractéristique générée.In this variant, when assembling the tube or the support respectively on the upper 11 and lower 12 parts of the assembly device 10, the microprocessor 29 generates, in real time, from the measurement signal SM coming from the sensor d acceleration 26, a characteristic curve representative of the evolution of the measured acceleration. The microprocessor 29 then generates and transfers to the memory 30, data D representative of said generated characteristic curve.
Dans un temps ultérieur, lorsque le dispositif d'assemblage 10 est placé dans une zone où la communication entre l'étiquette radiofréquence 14 et l'unité de contrôle 31 est possible et que le signal de porteuse P est émis par l'unité de contrôle 31 et reçu par l'antenne 27, le signal de porteuse P sert uniquement de signal d'interrogation. A partir du signal de porteuse P, le microprocesseur 29 génère, à partir des données D stockées dans la mémoire 30, un signal d'excitation SE représentatif de la courbe caractéristique générée préalablement. A partir du signal d'excitation SE, l'antenne 27 de l'étiquette radiofréquence 14 génère un signal de contrôle SC représentatif de ladite courbe caractéristique. Le signal de contrôle SC est reçu par l'unité de contrôle 31 , laquelle fonctionne alors de la manière décrite ci-dessus.In a later time, when the assembly device 10 is placed in an area where the communication between the radiofrequency label 14 and the control unit 31 is possible and the carrier signal P is transmitted by the control unit 31 and received by the antenna 27, the carrier signal P serves only interrogation signal. From the carrier signal P, the microprocessor 29 generates, from the data D stored in the memory 30, an excitation signal SE representative of the characteristic curve previously generated. From the excitation signal SE, the antenna 27 of the radiofrequency tag 14 generates a control signal SC representative of said characteristic curve. The control signal SC is received by the control unit 31, which then operates as described above.
Dans certaines variantes, le capteur d'accélération 26 communique par radiofréquence avec la puce 28 de l'étiquette radiofréquence 14 par l'intermédiaire de l'antenne 27 ou d'une troisième antenne (non représentée) prévue dans l'étiquette radiofréquence 14 et accordée sur une troisième fréquence prédéterminée.In some embodiments, the acceleration sensor 26 communicates by radio frequency with the chip 28 of the radiofrequency tag 14 via the antenna 27 or a third antenna (not shown) provided in the radiofrequency tag 14 and tuned to a third predetermined frequency.
Les figures 5 à 7 illustrent un deuxième mode de réalisation de dispositif d'assemblage selon l'invention. Le dispositif d'assemblage, repéré 40, comporte une embase 41 destinée à être collée sur un support (non représenté), à partir de laquelle s'étend un corps allongé 42 pour l'emboîtement à force d'un manchon (non représenté) prévu sur un élément de construction à assembler avec le support. Dans la variante représentée, l'embase 41 présente une épaisseur faible et est constituée d'un collage d'une partie inférieure d'embase 41a et d'une partie supérieure d'embase 41b. La face inférieure de la partie inférieure d'embase 41a est destinée à être collée sur le support et sa face supérieure est destinée à être solidarisée contre la face inférieure de la partie supérieure d'embase 41b. Le corps allongé s'étend depuis la face supérieure de la partie supérieure d'embase 41b, en formant un angle légèrement incliné par rapport à la droite perpendiculaire. La valeur de l'angle incliné dépend de l'agencement relatif entre le support et le manchon de l'élément de construction à assembler avec le support.Figures 5 to 7 illustrate a second embodiment of assembly device according to the invention. The assembly device, marked 40, comprises a base 41 intended to be glued on a support (not shown), from which extends an elongate body 42 for the interlocking force of a sleeve (not shown). provided on a construction element to be assembled with the support. In the variant shown, the base 41 has a small thickness and consists of a bonding of a lower base portion 41a and an upper base portion 41b. The lower face of the lower base portion 41a is intended to be glued to the support and its upper face is intended to be secured. against the lower face of the upper base portion 41b. The elongate body extends from the upper face of the upper base portion 41b, forming a slightly inclined angle with respect to the perpendicular line. The value of the inclined angle depends on the relative arrangement between the support and the sleeve of the construction element to be assembled with the support.
Le corps allongé 42 est constitué d'une portion cylindrique 43 se dressant depuis la face supérieure de la partie supérieure d'embase 41b, et d'une pluralité d'ailettes radiales 44 (au nombre de trois dans l'exemple illustre) s'étendant axialement dans le prolongement de la portion cylindrique 43. Des nervures de butée 45 se dressent entre la face supérieure de la partie supérieure d'embase 41b et la base de la portion cylindrique 43 pour constituer une butée lors de l'emboîtement à force du manchon. La hauteur des nervures de butée 45 est adaptée suivant leur emplacement pour compenser l'angle d'inclinaison du corps allongé 42.The elongate body 42 consists of a cylindrical portion 43 rising from the upper face of the upper base portion 41b, and a plurality of radial fins 44 (three in number in the example shown). extending axially in the extension of the cylindrical portion 43. Stop ridges 45 are raised between the upper face of the upper base portion 41b and the base of the cylindrical portion 43 to form a stop when the interlocking force of the muff. The height of the abutment ribs 45 is adapted according to their location to compensate for the angle of inclination of the elongate body 42.
Sur la figure 6, la partie inférieure d'embase 41a est retournée par rapport à sa position de service, c'est-à-dire après son collage contre la face inférieure de l'embase supérieure 41b. En référence à la figure 6, la face inférieure de l'embase supérieure 41b comporte un évidement annulaire 46 pour loger l'étiquette radie-fréquence 14 du dispositif d'assemblage 10 précédemment décrit. Le maintien transversal de l'étiquette radie-fréquence 14 dans l'évidement annulaire 46 est assuré par un centreur 47 de forme cylindrique agencé au centre. L'étiquette radiofrèquence 14 est mise en place dans i'évidement annulaire 46 avant la fixation de la partie inférieure d'embase 41a.In FIG. 6, the base lower part 41a is turned over with respect to its service position, that is to say after its bonding against the lower face of the upper base 41b. Referring to Figure 6, the lower face of the upper base 41b has an annular recess 46 for housing the radie-frequency label 14 of the assembly device 10 described above. The transverse retention of the radiofrequency label 14 in the annular recess 46 is provided by a centralizer 47 of cylindrical shape arranged in the center. The radiofrequency tag 14 is put in place in the annular recess 46 before the fixing of the lower base portion 41a.
De manière complémentaire, la face supérieure de l'embase inférieure 41a comporte un évidement principal 48 de forme cylindrique pour la réception du centreur 47 pendant la fixation des parties inférieure et supérieure d'embase 41a, 41b. Un trou 49 débouchant sur la face inférieure de l'embase inférieure 41a est pratiqué au centre du fond de l'όvidement principal 48.In a complementary manner, the upper face of the lower base 41a has a main recess 48 of cylindrical shape for receiving the centralizer 47 during attachment of the lower and upper base portions 41a, 41b. A hole 49 opening on the underside of the lower base 41a is made in the center of the bottom of the main opening 48.
Par ailleurs, une cavité 50 de forme allongée est pratiquée dans la matière de la portion cylindrique 43 depuis le centre du centreur 47. L'axe d'orientation de la cavité 50 est orthogonal au plan de l'embase 41. L'ouverture de la cavité 50 coïncide avec le trou 49, de sorte que la cavité 50 communique avec l'extérieur lorsque les parties inférieure et supérieure d'embase 41a, 41b sont fixées l'une à l'autre. La cavité 50 est destinée à loger un capteur de température (non représenté), dont la fonction sera détaillée plus loin.Furthermore, a cavity 50 of elongate shape is formed in the material of the cylindrical portion 43 from the center of the centralizer 47. The orientation axis of the cavity 50 is orthogonal to the plane of the base 41. The opening of the cavity 50 coincides with the hole 49, so that the cavity 50 communicates with the outside when the lower and upper base portions 41a, 41b are fixed to one another. The cavity 50 is intended to house a temperature sensor (not shown), whose function will be detailed later.
Plus précisément, le dispositif d'assemblage 40 intègre un système de contrôle CR identique à celui intégré dans le dispositif d'assemblage 10, à la différence que le capteur d'accélération 26 est remplacé par le capteur de température mentionné ci-dessus. Ce dernier est destiné à mesurer la température à proximité de l'ouverture du trou 49 lors du collage de la face inférieure de la partie inférieure d'embase 41a sur le support.More specifically, the assembly device 40 integrates a control system CR identical to that integrated in the assembly device 10, with the difference that the acceleration sensor 26 is replaced by the temperature sensor mentioned above. The latter is intended to measure the temperature near the opening of the hole 49 during the bonding of the lower face of the lower base portion 41a on the support.
En pratique, lors de l'assemblage de l'élément de construction avec le support, le microprocesseur 29 génère une courbe caractéristique représentative de l'évolution de la température mesurée par le capteur de température pendant le collage de la face inférieure de la partie inférieure d'embase 41a sur le support. Ladite courbe caractéristique est transmise, en temps réel ou ultérieurement suivant les applications, à l'unité de contrôle 31 pour pratiquer une comparaison avec une courbe spécifique prédéterminée. Le résultat de cette comparaison permet de vérifier que l'assemblage a été réalisé et de statuer sur la qualité de l'assemblage réalisé.In practice, during the assembly of the construction element with the support, the microprocessor 29 generates a characteristic curve representative of the evolution of the temperature measured by the temperature sensor during the bonding of the lower face of the lower part. base 41a on the support. Said characteristic curve is transmitted, in real time or subsequently according to the applications, to the control unit 31 to make a comparison with a predetermined specific curve. The result of this comparison makes it possible to verify that the assembly has been made and to decide on the quality of the assembly made.
Enfin, l'invention peut être appliquée à tout dispositif d'assemblage de deux éléments de construction pour lequel il est possible de mesurer, lors de l'assemblage, un paramètre physique de contrôle de l'assemblage. Les capteurs de mesure utilisés dans les systèmes de contrôle CR intégrés peuvent par exemple être du type capteur de pression, capteur de force, capteur de couple, capteur optique, capteur d'humidité, capteur d'énergie solaire, capteur piézoélectrique. D'autre part, suivant les variantes et les besoins, le capteur de mesure peut être situé à proximité des pièces du dispositif destinées à l'assemblage proprement dit, sans être intégré. Le système de contrôle CR est alors semi intégré. Finally, the invention can be applied to any assembly device of two construction elements for which it is possible to measure, during assembly, a physical parameter of control of the assembly. The Measuring sensors used in integrated CR control systems may for example be of the pressure sensor type, force sensor, torque sensor, optical sensor, humidity sensor, solar energy sensor, piezoelectric sensor. On the other hand, according to the variants and the needs, the measuring sensor can be located near the parts of the device intended for the assembly itself, without being integrated. The CR control system is then semi integrated.
