Description

DISPOSITIF DE TRANSFERT PAR PAQUETS DE COMPOSANTS PLANS ENTRE UN POSTE DE CHARGEMENT ET UN POSTE DE DECHARGEMENT.DEVICE FOR PACKET TRANSFER OF PLANT COMPONENTS BETWEEN A LOADING STATION AND AN UNLOADING STATION.
Domaine technique de l'invention. L'invention est du domaine des techniques de manipulation par paquets de composants plans au cours de leur fabrication, et notamment de plaques de silicium ou analogues. Elle a pour objet un dispositif de transfert de tels composants entre un poste de chargement et un poste de déchargement. Etat de la technique. On connaît des techniques de manipulation par paquets de composants plans, entre un poste de chargement et un poste de déchargement. Ces composants plans sont par exemple des plaquettes de silicium pour la réalisation de cellules solaires. On notera toutefois que la présente invention ne s'applique pas seulement à de telles plaquettes, mais à tout composant plan susceptible d'être transportés entre le poste de chargement et le poste de déchargement. De telles manipulations interviennent par exemple pour transférer des composants depuis au moins une nacelle de stockage vers au moins une nacelle de traitement, cette dernière permettant de recevoir les composants pour l'application d'un traitement dans un dispositif spécifique, tel qu'un traitement thermique ou autre traitement. Les composants sont disposés dans la nacelle de stockage en adjacence parallèlement dans leur plan général, et doivent être déplacés vers la nacelle de traitement, où ils sont à nouveau disposés parallèlement en adjacence. De manière habituelle, les nacelles de stockage et de traitement sont équipées de supports des composants, qui sont munis de peignes pour la réception des composants entre les dents des peignes. Ces dispositions visent à maintenir les composants parallèlement entre eux par l'intermédiaire de deux de leurs bords adjacents reposant sur les peignes. II est fréquent que le pas de séparation des dents des peignes de la nacelle de stockage soit différent de celui de la nacelle de traitement. En effet, pour optimiser l'exploitation du volume utile de la nacelle de traitement, le pas des peignes équipant cette dernière est réduit au mieux. Plus particulièrement, le pas des peignes de la nacelle de stockage correspond à un nombre multiple, et notamment au double, de celui des peignes de la nacelle de traitement. Se pose alors le problème de transférer les composants entre le poste de chargement et le poste de déchargement en modifiant leur pas de séparation entre celui correspondant aux peignes équipant la nacelle de stockage et celui correspondant aux peignes équipant la nacelle de traitement.Technical Field of the Invention The invention is in the field of packet manipulation techniques of planar components during their manufacture, and in particular silicon wafers or the like. It relates to a device for transferring such components between a loading station and an unloading station. State of the art Methods of packet manipulation of planar components between a loading station and an unloading station are known. These planar components are, for example, silicon wafers for the production of solar cells. Note, however, that the present invention does not apply only to such platelets, but to any plane component that can be transported between the loading station and the unloading station. Such manipulations occur for example to transfer components from at least one storage nacelle to at least one processing nacelle, the latter to receive the components for the application of a treatment in a specific device, such as a treatment thermal or other treatment. The components are arranged in the storage pod in parallel adjacency in their general plane, and must be moved to the processing pod, where they are again arranged parallel in adjacency. Typically, the storage and processing pods are equipped with component supports, which are provided with combs for receiving the components between the teeth of the combs. These provisions aim at keeping the components parallel to each other via two of their adjacent edges resting on the combs. It is common that the separation pitch of the teeth of the nacelle storage combs is different from that of the nacelle treatment. Indeed, to optimize the exploitation of the useful volume of the nacelle treatment, the pitch of the combs equipping the latter is reduced at best. More particularly, the pitch of the combs of the storage nacelle corresponds to a multiple number, and especially double, that of the combs of the nacelle treatment. There then arises the problem of transferring the components between the loading station and the unloading station by modifying their separation step between that corresponding to the combs equipping the storage nacelle and that corresponding to the combs equipping the nacelle treatment.
Selon une première technique connue, les composants sont transférés manuellement entre le poste de chargement et le poste de déchargement. Une telle technique, longue et fastidieuse, n'est pas satisfaisante au regard des cadences de transfert qui sont inappropriées et qui méritent d'être améliorées. En outre, compte tenu de la faible épaisseur des composants, une telle manipulation manuelle induit des risques de détérioration de ceux-ci, avec en conséquence un rebut important. C'est pourquoi il a été proposé des dispositifs de transfert mécanisé des composants entre le poste de chargement et le poste de déchargement. De tels dispositifs comportent une tête de transfert des composants, qui est mobile entre le poste de chargement dans lequel la tête de transfert saisit les composants disposés dans la nacelle de stockage, et le poste de déchargement dans lequel la tête de transfert dépose les composants dans la nacelle de traitement. Cette tête de transfert comporte deux mâchoires équipées de peignes, qui sont mobiles l'une vers l'autre pour saisir les composants par pincement en les happant par les bords de leurs tranches. Cependant, de tels moyens de saisie des composants sont insatisfaisants car ils sont source d'un risque de détérioration de ces derniers, en raison notamment des vibrations induites par la manoeuvre des mâchoires l'une vers l'autre. De surcroît, la présence de moyens de motorisation pour la manœuvre des mâchoires, outre le fait d'être une source potentielle de panne, n'est pas satisfaisante au regard d'un environnement des composants recherché protégé. De tels dispositifs, présentant des avantages par rapport à une manœuvre manuelle des composants, n'offrent cependant pas la faculté de modifier en toute sécurité pour les composants, le pas séparant les composants lors de leur transfert. Si des aménagements spécifiques pour la modification d'un tel pas sont envisageables pour le transfert de composants plus robustes que des cellules solaires, tels que pour des composants électroniques, la fragilité des cellules solaires rend la conception de tels agencements plus délicate. On notera qu'il est souhaitable que de tels agencements soient d'une organisation structurelle la plus simple possible, avec une mise en œuvre n'accroissant pas outre mesure la complexité globale du dispositif de transfert.According to a first known technique, the components are transferred manually between the loading station and the unloading station. Such a technique, which is long and tedious, is not satisfactory with regard to transfer rates which are inappropriate and which deserve to be improved. In addition, given the small thickness of the components, such manual handling induces the risk of deterioration thereof, with consequent significant rejection. This is why it has been proposed mechanisms mechanized transfer of components between the loading station and the unloading station. Such devices include a component transfer head, which is movable between the loading station in which the transfer head grasps the components arranged in the storage pod, and the unloading station in which the transfer head deposits the components in the nacelle of treatment. This transfer head has two jaws equipped with combs, which are movable towards each other to grip the components by pinching by catching them by the edges of their slices. However, such means of capturing the components are unsatisfactory because they are a source of a risk of deterioration of the latter, especially because of the vibrations induced by the jaws maneuver towards each other. In addition, the presence of motorization means for operating the jaws, in addition to being a potential source of failure, is not satisfactory with respect to an environment of protected components sought. Such devices, having advantages over a manual operation of the components, however do not offer the ability to change safely for the components, the step separating the components during their transfer. If specific arrangements for the modification of such a step are possible for the transfer of more robust components than solar cells, such as for electronic components, the fragility of solar cells makes the design of such arrangements more difficult. It should be noted that it is desirable for such arrangements to be of the simplest possible structural organization, with an implementation that does not unduly increase the overall complexity of the transfer device.
En outre, il est souhaitable qu'un même dispositif puisse être utilisé alternativement pour des composants de tailles significativement différentes. La saisie des composants par resserrement des mâchoires rend les réglages des positions relatives des mâchoires d'une taille à l'autre des composants qui sont délicats et fastidieux, avec en corollaire un rendement de la disponibilité d'utilisation du dispositif qui est insatisfaisant. Ces réglages méritent donc d'être simplifiés. Objet de l'invention.In addition, it is desirable that the same device can be used alternately for components of significantly different sizes. The gripping of the components by tightening the jaws makes the adjustments of the relative positions of the jaws from one size to another of the components that are delicate and tedious, with consequent efficiency of the availability of use of the device which is unsatisfactory. These settings deserve to be simplified. Object of the invention

It is more particularly targeted by the present invention to provide such a device which is simple in structure and whose implementation allows its operation at high rates, while allowing the mechanized transfer of components without risk of alteration thereof, including for particularly fragile components such as solar cells.
Il est aussi visé par la présente invention de permettre un tel transfert mécanisé des composants offrant la possibilité de modifier lors de leur transfert l'écart, ou pas, les séparant les uns des autres respectivement au poste de chargement et au poste de déchargement. Plus particulièrement encore, il est visé de proposer un tel dispositif permettant rapidement et aisément son adaptation au transfert de composants de dimensions, voire de conformation, significativement différentes.It is also the object of the present invention to allow such a mechanized transfer of the components offering the possibility of modifying during their transfer the difference, or not, separating them from each other respectively at the loading station and at the unloading station. More particularly, it is intended to propose such a device that allows for rapid and easily its adaptation to the transfer of components of dimensions, or even conformation, significantly different.
Le dispositif de la présente invention est reconnaissable en ce qu'il comprend un bâti supportant un premier châssis de réception d'au moins une nacelle de stockage des composants. Ce premier châssis est placé au poste de chargement. Le bâti supporte en outre un deuxième châssis supportant au moins une nacelle de traitement des composants. Ce deuxième châssis est placé au poste de déchargement. Les nacelles de stockage et de traitement sont équipées de supports de peignes de maintien des composants parallèlement les uns aux autres dans leur plan général. Le pas des peignes équipant la nacelle de stockage est plus important d'un multiple du pas des peignes équipant la nacelle de traitement. On notera que les premier et deuxième châssis sont plus particulièrement ajourés dans la zone de soutien respectivement de la nacelle de stockage et de la nacelle de traitement, et que les nacelles de stockage et de traitement sont plus particulièrement agencées en cage ou analogue, pour permettre le passage à leur travers d'une nacelle de transfert portée par une colonne élévatrice tel qu'il sera décrit plus loin.The device of the present invention is recognizable in that it comprises a frame supporting a first receiving frame of at least one component storage pod. This first frame is placed at the loading station. The frame further supports a second frame supporting at least one component processing pod. This second frame is placed at the unloading station. The storage and processing pods are equipped with support brackets for holding the components parallel to each other in their general plan. The pitch of the combs equipping the storage nacelle is greater by a multiple of the pitch of the combs equipping the nacelle of treatment. It will be noted that the first and second frames are more particularly perforated in the support zone respectively of the storage nacelle and the processing nacelle, and that the storage and processing nacelles are more particularly arranged in a cage or the like, to enable passing through them a transfer pod carried by a lift column as will be described later.
Le bâti est en outre porteur d'au moins une tête de transfert, qui est mobile entre le poste de chargement et le poste de déchargement en surplomb de ces derniers. Cette tête de transfert comporte au moins un jeu de supports en vis-à-vis équipés de peignes pour maintenir les composants parallèlement les uns aux autres dans leur plan général, lors de leur transfert depuis le poste de chargement vers le poste de déchargement. Ces supports sont plus particulièrement disposés sur la tête de transfert en ménageant un espace entre eux, pour le passage de ladite nacelle de transfert tel qu'il sera décrit plus loin.The frame is also carrying at least one transfer head, which is movable between the loading station and the unloading station overhanging them. This transfer head comprises at least one set of supports in vis-à-vis equipped with combs to keep the components parallel to each other in their general plan, during their transfer from the loading station to the unloading station. These supports are more particularly arranged on the transfer head by providing a space between them, for the passage of said transfer pod as will be described later.
Le dispositif est en outre équipé de moyens de préhension au poste de chargement successivement de paquets de composants en nombre correspondant au dit multiple. Le dispositif est aussi équipé de moyens de dépôt, sur un jeu de dit supports équipant la tête de transfert, des dits paquets de composants en interposition séquentielle de ces derniers d'un composant à l'autre des dits paquets.The device is further equipped with gripping means at the loading station successively packets of components in number corresponding to said multiple. The device is also equipped with means for depositing, on a set of said media equipping the transfer head, said packets of components in sequential interposition of the latter from one component to the other of said packets.
Selon une forme préférée de réalisation, les dits moyens de préhension comprennent une colonne élévatrice porteuse d'une nacelle de transfert des composants vers la tête de transfert. Lesdits moyens de dépôt associent quant à eux un premier jeu de dits supports pour la réception d'un premier paquet de composants, les dits moyens de préhension pour la saisie d'au moins un deuxième paquet de composants conjointement avec le premier paquet de composants préalablement déposé sur ledit premier jeu de supports, et un deuxième jeu de dits supports pour la réception conjointe des dits premier et deuxième paquets de composants portés par les moyens de préhension.According to a preferred embodiment, said gripping means comprise an elevating column carrying a nacelle for transferring the components to the transfer head. Said depositing means associates a first set of said supports for receiving a first packet of components, said gripping means for entering at least a second package of components together with the first package of components previously deposited on said first set of supports, and a second set of said supports for the joint reception of said first and second packets of components carried by the gripping means.
Plus particulièrement, les jeux de supports sont au moins en nombre correspondant au dit multiple. Les peignes des supports d'un premier jeu comportent alternativement des fentes borgnes et des fentes débouchantes, tandis que les peignes des supports d'un deuxième jeu comportent des fentes borgnes. Le pas d'espacement des fentes borgnes des peignes équipant les supports du premier jeu correspond au pas des peignes équipant la nacelle de stockage, et correspond au dit multiple du pas d'espacement des fentes borgnes des peignes équipant les supports du deuxième jeu.More particularly, the media sets are at least in number corresponding to said multiple. The combs of the supports of a first game comprise alternately blind slots and open slots, while the combs of the supports of a second set comprise blind slots. The spacing pitch of the blind slots of the combs equipping the supports of the first set corresponds to the pitch of the combs equipping the storage nacelle, and corresponds to the said multiple of the spacing pitch of the blind slots of the combs equipping the supports of the second set.
Le dispositif comprend en outre au moins un chariot monté mobile sur le bâti entre lesdits premier et deuxième châssis. Ce chariot est porteur d'une colonne élévatrice porteuse elle-même d'une nacelle de transfert équipée de peignes de maintien des composants parallèlement les uns aux autres dans leur plan général. Le pas des peignes équipant la nacelle de transfert correspond au pas des peignes équipant la nacelle de traitement.The device further comprises at least one carriage mounted movably on the frame between said first and second frame. This carriage carries a lift column itself carrying a transfer pod equipped with holding combs components parallel to each other in their general plan. The pitch of the combs equipping the transfer nacelle corresponds to the pitch of the combs equipping the nacelle treatment.
Le dispositif comprend en outre des moyens de commande et de manoeuvre respective du chariot, de la colonne élévatrice et de la tête de transfert, pour accomplir un cycle de fonctionnement du dispositif comprenant les étapes suivantes :The device further comprises respective control and operating means of the carriage, the lifting column and the transfer head, to accomplish a cycle of operation of the device comprising the following steps:
*) éloigner la tête de transfert du surplomb d'une première nacelle de stockage porteuse d'un premier paquet de composants, *) placer le chariot sous la première nacelle et manœuvrer la colonne élévatrice en un mouvement ascendant au cours duquel la nacelle de transfert traverse le premier châssis en circulant entre les peignes de la première nacelle de stockage pour saisir par soutien le premier paquet de composants et placer ce paquet au dessus du premier châssis, *) déplacer la tête de transfert et disposer les supports du premier jeu de part et d'autre des composants du premier paquet, les fentes borgnes des peignes étant situés en regard des tranches des composants,*) move the transfer head from the overhang of a first carrier storage pod to a first package of components, *) place the truck under the first platform and maneuver the lift column in an upward motion during which the transfer pod traverses the first frame by moving between the combs of the first storage pod to grab the first package of components by support and place this package on top of the first frame, *) move the transfer head and arrange the supports of the first game from and other components of the first package, the blind slots of the combs being located opposite the slices of the components,
*) abaisser la colonne élévatrice et disposer la nacelle de transfert en position initiale, les composants du premier paquet étant retenus par les fentes borgnes des peignes équipant les supports du premier jeu, *) déplacer la tête de transfert en disposant les supports du premier jeu en surplomb d'une deuxième nacelle de stockage porteuse d'un deuxième paquet de composants, les fentes débouchantes des peignes équipant les supports du premier jeu étant situées en regard des composants du deuxième paquet,*) lower the lift column and have the transfer pod in the initial position, the components of the first package being retained by the blind slots of the combs equipping the supports of the first game, *) move the transfer head by arranging the supports of the first game overhanging a second storage nacelle carrying a second package of components, the open slots of the combs equipping the supports of the first set being located opposite the components of the second package,
*) placer le chariot sous la deuxième nacelle et manœuvrer la colonne élévatrice en un mouvement ascendant au cours duquel la nacelle de transfert traverse le premier châssis en circulant entre les peignes de la deuxième nacelle de stockage pour saisir par soutien le deuxième paquet de composants et l'acheminer entre les supports du premier jeu, les composants traversant les fentes débouchantes des peignes équipant ces supports et étant alternativement intercalés entre les composants du premier paquet, et faire poursuivre le mouvement ascendant de la colonne élévatrice, la nacelle de transfert saisissant par soutien les premier et deuxième paquets de composants,*) place the carriage under the second platform and maneuver the lift column in an upward movement during which the transfer pod passes through the first frame by circulating between the combs of the second storage pod to seize by support the second package of components and transporting it between the supports of the first game, the components passing through the opening slots of the combs equipping these supports and being alternately interposed between the components of the first package, and continuing the upward movement of the lifting column, the grabbing transfer pod by support the first and second component packets,
*) déplacer la tête de transfert et disposer les supports du deuxième jeu de part et d'autre des composants des premier et deuxième paquets, les fentes borgnes des peignes étant situées en regard des tranches des composants, *) abaisser la colonne élévatrice et disposer la nacelle de transfert en position initiale, les composants des premier et deuxième paquets étant retenus par les fentes borgnes des peignes équipant les supports du deuxième jeu,*) move the transfer head and arrange the supports of the second set on either side of the components of the first and second packets, the blind slots of the combs being located opposite the slices of the components, * ) lower the lift column and arrange the transfer pod in the initial position, the components of the first and second packets being retained by the blind slots of the combs equipping the supports of the second set,
*) le cas échéant, lorsque les supports du deuxième jeu sont en pluralité, répéter les opérations de préhension des composants d'un paquet de composants par la nacelle de transfert, et de dépôt de ces composants correspondant à un nouveau deuxième paquet dans les supports du premier jeu en interposition séquentielle avec les composants des paquets préalablement déposés, *) déplacer la tête de transfert vers le poste de déchargement en disposant les supports du deuxième jeu en surplomb de la nacelle de traitement, * ) if necessary, when the supports of the second set are in plurality, repeating the operations of gripping the components of a package of components by the transfer basket, and depositing these components corresponding to a new second package in the supports the first game in sequential interposition with the components of previously deposited packets, *) move the transfer head to the unloading station by arranging the supports of the second game overhanging the processing nacelle,
*) déplacer le chariot vers le poste de déchargement en disposant la nacelle de transfert sous la nacelle de traitement, et manœuvrer la colonne élévatrice en un mouvement ascendant au cours duquel la nacelle de transfert traverse le deuxième châssis en circulant entre les peignes de la nacelle de traitement, et faire poursuivre le mouvement ascendant de la colonne élévatrice jusqu'entre les supports du deuxième jeu, la nacelle de transfert saisissant par soutien le premier et le deuxième paquet de composants,*) move the trolley to the unloading station by arranging the transfer basket under the processing nacelle, and maneuver the lift column in an upward movement during which the transfer nacelle passes through the second frame by circulating between the nacelle combs processing, and continue the upward movement of the riser up between the supports of the second set, the transfer basket grabbing by supporting the first and the second package of components,
*) éloigner la tête de transfert du surplomb de la nacelle de traitement, et abaisser la colonne élévatrice pour disposer la nacelle de transfert en position initiale, les composants étant retenus par les peignes de la nacelle de traitement. Ces dispositions sont telles que les paquets des composants déposés dans la nacelle de traitement sont espacés d'un pas correspondant à l'inverse du dit multiple du pas d'espacement des composants placés dans la nacelle de stockage. La modification du pas séparant les composants est plus particulièrement obtenue en interposant séquentiellement les composants du deuxième paquet entre les composants du premier paquet préalablement déposés sur le deuxième support. Par exemple, selon la forme préférée de réalisation selon laquelle le pas d'espacement entre les peignes équipant la nacelle de stockage correspond au double du pas de la nacelle de traitement, les composants du premier paquet et ceux du deuxième paquet seront placés en alternance sur les supports du deuxième jeu de la tête de transfert. Dans ce cas, le pas d'espacement des fentes borgnes des peignes équipant les supports du premier jeu correspond au double du pas d'espacement des fentes des peignes des supports du deuxième jeu.*) move the transfer head from the overhead of the processing nacelle, and lower the lift column to arrange the transfer nacelle in the initial position, the components being retained by the combs of the nacelle treatment. These arrangements are such that the packets of the components deposited in the processing nacelle are spaced by a step corresponding to the inverse of said multiple of spacing step of the components placed in the storage nacelle. The modification of the pitch separating the components is more particularly obtained by sequentially interposing the components of the second packet between the components of the first packet previously deposited on the second support. For example, according to the preferred embodiment in which the spacing pitch between the combs equipping the storage nacelle is twice the step of the processing nacelle, the components of the first packet and those of the second packet will be placed alternately on the supports of the second set of the transfer head. In this case, the spacing pitch of the blind slots of the combs equipping the supports of the first set corresponds to twice the spacing pitch of the slots of the combs of the supports of the second set.
Il en ressort une optimisation de l'exploitation du volume utile de la nacelle de traitement. On comprendra que cette dernière est susceptible de recevoir un nombre quelconque de paquets de composants successivement transférés depuis le poste de chargement. Par ailleurs, la modification du pas d'espacement des composants entre le poste de chargement et le poste de déchargement a avantageusement été opérée de manière mécanisée, avec pour avantage de permettre des cadences satisfaisantes de transfert des composants, malgré la dite modification du pas les séparant les uns des autres. En outre, la manipulation des composants, tant lors de leur déplacement que lors du changement de leur maintien d'un organe à l'autre du dispositif, s'effectue sans prise des composants mais par simple soutien de ces derniers par leurs tranches, avec pour avantage d'éviter leur détérioration, y compris pour des composants particulièrement fragiles tels que des cellules solaires.It shows an optimization of the exploitation of the useful volume of the nacelle of treatment. It will be understood that the latter is capable of receiving any number of packets of components successively transferred from the loading station. Moreover, the modification of the spacing pitch of the components between the loading station and the unloading station has advantageously been operated in a mechanized manner, with the advantage of allowing satisfactory rates of transfer of the components, despite said modification of the pitch. separating from each other. In addition, the manipulation of the components, both during their displacement and during the change of their maintenance of an organ to the other of the device, is performed without taking the components but simply by supporting them by their slices, with the advantage of avoiding their deterioration, including for particularly fragile components such as cells solar.
De préférence, le dispositif comporte au moins deux jeux de deux nacelles de stockage supportés par le premier châssis. Les nacelles de stockage d'un même jeu sont notamment disposées en adjacence longitudinale, selon plus particulièrement une variante de réalisation dans laquelle la tête de transfert et le chariot sont montés mobiles sur le bâti en translation. Le premier châssis est monté mobile sur le bâti entre deux positions alternatives, dont une première position dans laquelle un premier jeu de nacelles de stockage est en position de déchargement, et dans laquelle un deuxième jeu de nacelles de stockage est en position d'attente, et une deuxième position dans laquelle ledit deuxième jeu est en position de déchargement et ledit premier jeu en position d'attente. Ces dispositions sont telles que lors du transfert des composants hors du premier jeu de nacelles de stockage, le deuxième jeu de nacelles de stockage peut être chargé sur le premier châssis, puis les nacelles de stockage étant déchargées, être placé en position de déchargement par interversion des positions du premier châssis entre ses première et deuxième positions.Preferably, the device comprises at least two sets of two storage pods supported by the first frame. Storage nacelles of the same set are in particular arranged in longitudinal adjacency, according to more particularly an embodiment wherein the transfer head and the carriage are movably mounted on the frame in translation. The first frame is movably mounted on the frame between two alternative positions, including a first position in which a first set of storage pods is in the unloading position, and in which a second set of storage pods is in the waiting position, and a second position in which said second game is in unloading position and said first game in standby position. These arrangements are such that during the transfer of the components out of the first set of storage pods, the second set of storage pods can be loaded on the first frame, then the storage pods are unloaded, be placed in the position of unloading by reversal positions of the first frame between its first and second positions.
Le premier châssis est par exemple monté mobile entre ses première et deuxième positions par pivotement sur le bâti dans son plan général autour d'un axe médian.The first frame is for example movably mounted between its first and second positions by pivoting on the frame in its general plane around a central axis.
Selon une forme préférée de réalisation, les premier et deuxième jeux de supports équipant la tête de transfert sont disposés en prolongement l'un de l'autre. La tête de transfert et le chariot sont manœuvrables en translation sur le bâti le long d'un premier et d'un deuxième rail respectif porté par le bâti et s'étendant entre le poste de chargement et le poste de déchargement.According to a preferred embodiment, the first and second sets of supports equipping the transfer head are arranged in extension of one another. The transfer head and the carriage are operable in translation on the frame along a respective first and second rail carried by the frame and extending between the loading station and the unloading station.
La nacelle de traitement est notamment équipée de peignes dont les dents sont inclinées d'un angle A par rapport à l'aplomb de l'assise que prend la nacelle de traitement sur le deuxième châssis, celui-ci étant porté par le bâti parallèlement au sol. Ces dispositions visent à maintenir les composants sur la nacelle de traitement de manière légèrement inclinée suivant ledit angle A, de l'ordre de 3° par exemple, afin de conforter leur immobilisation en position de soutien lors de l'opération ultérieure de traitement. Dans ce cas, les premier et deuxième rails, ainsi que le premier châssis, sont avantageusement portés par le bâti en étant inclinés par rapport au sol du dit angle A. L'axe de manœuvre de la colonne élévatrice est quant à lui avantageusement incliné par rapport à l'aplomb du dit angle A, suivant sa direction d'élévation. Il ressort de ces dispositions que lors du transfert des composants, ceux-ci sont soutenus et déplacés suivant l'angle A d'inclinaison correspondant à celui de soutien des composants à l'intérieur de la nacelle de traitement.The treatment nacelle is in particular equipped with combs whose teeth are inclined at an angle A relative to the plumb of the seat that takes the processing pod on the second frame, the latter being carried by the frame parallel to the ground. These provisions are intended to maintain the components on the nacelle treatment slightly inclined at said angle A, of the order of 3 ° for example, to strengthen their immobilization in the support position during the subsequent treatment operation. In this case, the first and second rails, as well as the first frame, are advantageously carried by the frame being inclined relative to the ground of said angle A. The axis of maneuver of the riser is advantageously inclined by relative to said angle A, according to its elevation direction. It follows from these provisions that during the transfer of the components, they are supported and moved according to the angle of inclination corresponding to the support of the components inside the nacelle treatment.
Les supports de la tête de transfert sont plus particulièrement portés aux extrémités respectives de bras coudés fixés dans leur zone médiane d'inflexion à un organe de transfert monté mobile sur le bâti, notamment pour ménager sans gêne le dit passage de la nacelle de transfert. Dans le cas où la tête de transfert est mobile en translation sur le bâti, ledit organe de transfert est notamment agencé en chariot circulant le long du premier rail.The supports of the transfer head are more particularly carried at the respective ends of bent arms fixed in their median zone of inflection to a transfer member mounted to move on the frame, in particular for unhindered handling of said passage of the nacelle. transfer. In the case where the transfer head is movable in translation on the frame, said transfer member is in particular arranged in a carriage running along the first rail.
La tête de transfert est de préférence équipée de moyens de réglage de la position relative des supports d'un même jeu l'un par rapport à l'autre. Ces moyens de réglage sont avantageusement des moyens de réglage discret mettant en œuvre des moyens du type par brochage. Ces dispositions sont telles que le réglage de l'écartement des supports équipant la tête de transfert est susceptible d'être réalisé rapidement et aisément, pour être adapté selon des dimensions prédéterminées et significativement différentes des composants destinés à être transférés. II est néanmoins envisageable d'agencer les moyens de réglage en moyens à variation continue de la position relative des supports d'un même jeu, un tel agencement présentant toutefois l'inconvénient de rendre plus délicat la mise en œuvre des moyens de réglage.The transfer head is preferably equipped with means for adjusting the relative position of the supports of the same set relative to each other. These adjustment means are advantageously discrete adjustment means implementing means of the type by broaching. These arrangements are such that the adjustment of the spacing of the media equipping the transfer head is likely to be achieved quickly and easily, to be adapted to predetermined dimensions and significantly different components to be transferred. Nevertheless, it is conceivable to arrange the means of adjustment in continuously variable means of the relative position of the supports of the same set, such an arrangement however having the drawback of making the implementation of the adjustment means more difficult.
Selon un exemple préféré de réalisation desdits moyens de réglage par brochage, ceux- ci associent notamment des broches traversant un organe respectif de soutien des supports par leurs extrémités correspondantes, ces organes de soutien étant fixés sur la tête de transfert. La broche coopère en outre sélectivement avec une pluralité d'ouvertures ménagées à travers les supports à leurs extrémités. Selon la forme préférée de réalisation selon laquelle les supports sont montés sur la tête de transfert par l'intermédiaire de bras coudés, les organes de soutien des supports sont préférentiellement fixés aux extrémités des bras coudés, et sont agencés en collier de réception par coulissement d'une colonne respective de guidage des supports.According to a preferred embodiment of said broaching adjustment means, these associate in particular pins passing through a respective support member supports by their corresponding ends, these support members being fixed on the transfer head. The pin further selectively cooperates with a plurality of openings formed through the supports at their ends. According to the preferred embodiment in which the supports are mounted on the transfer head by means of bent arms, the support members of the supports are preferably fixed to the ends of the bent arms, and are arranged as a sliding receiving collar. a respective column for guiding the supports.
On notera que les moyens de manœuvre respectivement de la tête de transfert et du chariot sont de préférence des moyens de manœuvre indépendants.It should be noted that the means of maneuver respectively of the transfer head and the carriage are preferably independent maneuvering means.
Les composants sont susceptibles de comporter deux tranches inclinées orthogonalement l'une par rapport à l'autre. Par exemple, les composants sont globalement conformés en plaque parallélépipédique, et notamment carrée. Selon un autre exemple de conformation des composants, ceux-ci sont susceptibles d'être conformés en disque ou analogue. Les peignes équipant respectivement les nacelles de stockage, de traitement et de transfert, et équipant respectivement les supports de la tête de transfert, sont de préférence inclinés en vis-à-vis d'un angle de 45°, pour saisir les composants par les deux dites tranches, et notamment par deux de leurs bords adjacents.The components may have two slices inclined orthogonally relative to each other. For example, the components are generally shaped parallelepiped plate, and in particular square. According to another example of conformation of the components, these are likely to be shaped disk or the like. The combs equipping respectively the storage, processing and transfer pods, respectively equipping the supports of the transfer head, are preferably inclined in relation to an angle of 45 °, to grasp the components by the two said slices, and in particular two of their adjacent edges.
Avantageusement, le dispositif est susceptible d'être équipé de moyens de réglage de l'inclinaison l'un par rapport à l'autre des peignes coopérants, le réglage de cette inclinaison étant effectué selon la conformation des composants à transférer. Description des figures. La présente invention sera mieux comprise, et des détails en relevant apparaîtront, à la lecture de la description qui va en être faite en relation avec les figures des planches annexées, dans lesquelles : Les fig.1 et fig.2 sont des illustrations d'ensemble d'un dispositif de transfert de composants plans selon un exemple de réalisation de la présente invention, respectivement vu en perspective et vu de face.Advantageously, the device may be equipped with means for adjusting the inclination relative to each other of the cooperating combs, the adjustment of this inclination being effected according to the conformation of the components to be transferred. Description of the figures. The present invention will be better understood and details will arise from reading the description which will be made in connection with the figures of the attached plates, in which: FIGS. 1 and 2 are general illustrations of a device for transferring planar components according to an exemplary embodiment of the present invention, respectively seen in perspective and viewed from the front.
La fig.3 est une vue en perspective d'une tête de transfert équipant le dispositif illustré sur les fig.1 et fig.2.Fig.3 is a perspective view of a transfer head equipping the device shown in Fig.1 and Fig.2.
Les fig.4 et fig.5 sont des détails de peignes équipant la tête de transfert illustrée sur la fig.3. La fig.6 est une vue en perspective d'un premier châssis équipant le dispositif illustré sur les fig.1 et fig.2. La fig.7 est une vue en perspective d'un chariot équipant le dispositif illustré sur les fig.1 et fig.2. Les fig.8 à fig.16 sont des schémas d'un dispositif de l'invention tel que représenté sur les fig.1 et fig.2, illustrant successivement ses modalités de mise en œuvre.Fig.4 and fig.5 are details of combs equipping the transfer head shown in Fig.3. Fig.6 is a perspective view of a first frame equipping the device shown in Fig.1 and Fig.2. Fig.7 is a perspective view of a carriage equipping the device shown in Fig.1 and Fig.2. Fig.8 to Fig.16 are diagrams of a device of the invention as shown in Fig.1 and Fig.2, illustrating successively its implementation.
Sur les fig.1 et fig.2, le dispositif représenté est destiné au transfert de composants plans entre un poste de chargement 1 et un poste de déchargement 2. Des nacelles de stockage 3 sont placées au poste de chargement 1 et une nacelle de traitement 4 est placée au poste de déchargement 2. Ces nacelles 3 et 4 sont respectivement supportées par un premier châssis 5 et un deuxième châssis 6, installés sur un bâti 7. Les nacelles de stockage 3 et de traitement 4 sont équipés de peignes pour maintenir les composants parallèlement dans leur plan général.In FIGS. 1 and 2, the device shown is intended for the transfer of planar components between a loading station 1 and an unloading station 2. Storage pods 3 are placed at the loading station 1 and a processing pod. 4 is placed at the unloading station 2. These nacelles 3 and 4 are supported respectively by a first frame 5 and a second frame 6, installed on a frame 7. The storage nacelles 3 and 4 treatment are equipped with combs to maintain the components parallel in their general plan.
Un problème posé réside dans le fait que le pas des peignes des nacelles de stockage 3 n'est pas égal à celui des peignes de la nacelle de traitement 4. Plus particulièrement le pas des peignes des nacelles de stockage 3 correspond à un multiple de celui des peignes de la nacelle de traitement 4. Il est donc visé par l'invention de permettre le transfert des composants entre le poste de chargement 1 et le poste de déchargement 2, en modifiant leur pas d'écartement. Le dispositif de l'invention permet une telle modification d'écartement entre les composants en intercalant, lors de leur transfert entre le poste de chargement 1 et le poste de déchargement 2, les composants d'un premier paquet séquentiellement entre les composants d'au moins un deuxième paquet. Sur l'exemple de réalisation illustré sur les figures, ledit multiple correspond au double. Il doit cependant être compris que selon l'invention ce multiple pourrait correspondre à un nombre entier supérieur, les dispositions prévues pour compenser l'écart des composants entre eux lors de leur transfert depuis les nacelles de stockage 3 vers la nacelle de traitement 4 sont transposables à un quelconque dit multiple.A problem lies in the fact that the pitch of the nacelles of the storage pods 3 is not equal to that of the combs of the treatment nacelle 4. More particularly, the pitch of the nacelles of the storage nacelles 3 corresponds to a multiple of the It is therefore the object of the invention to allow the transfer of the components between the loading station 1 and the unloading station 2, by modifying their spacing pitch. The device of the invention allows such a change in spacing between the components by intercalating, during their transfer between the loading station 1 and the unloading station 2, the components of a first packet sequentially between the components of the less a second package. In the exemplary embodiment illustrated in the figures, said multiple corresponds to twice. However, it should be understood that according to the invention this multiple could correspond to a higher whole number, the arrangements for compensating for the difference between the components when they are transferred from the storage pods 3 to the treatment pod 4 are transposable. to any one said multiple.
Un autre problème posé réside dans la faiblesse des composants, qui sont susceptibles d'être particulièrement fragiles, tels que des composants constitués de cellules solaires. Il en ressort que leur transfert doit être opéré en évitant rigoureusement toute détérioration de ceux- ci. C'est pourquoi il est non seulement proposé la solution susvisée de modification de l'écart séparant les composants à partir de leur mise en interposition d'un paquet à l'autre, mais aussi de les manipuler uniquement par soutien, sans saisie des composants par pression, tels qu'au moyen de mâchoires mobiles l'une vers l'autre à la manière connue de l'art antérieur.Another problem lies in the weakness of the components, which are likely to be particularly fragile, such as components consisting of solar cells. It follows that their transfer must be made by strictly avoiding any deterioration thereof. This is why it is not only proposed the aforementioned solution for changing the gap between the components from their interposition of a package to another, but also to handle them only by support, without seizing components by pressure, such as by means of jaws movable towards each other in the manner known from the prior art.
Le dispositif illustré comporte une tête de transfert 8 mobile le long d'un premier rail 9 supporté par le bâti 7. En se reportant par ailleurs sur la fig.3, cette tête de transfert 8 supporte deux jeux 10 et 11 de supports 12, supportant eux-mêmes chacun un peigne 13 ou 14. Les peignes 13 ou 14 sont disposés en regard l'un de l'autre pour les supports 12 d'un même jeu 10 ou 11 , en ménageant entre eux un espace pour le passage des composants, tel qu'il sera décrit plus loin. En se reportant par ailleurs sur les fig.4 et fig.5, les peignes 13 équipant les supports 12 d'un premier jeu 10 comportent des fentes débouchantes 15 et des fentes borgnes 16, tandis que les peignes 14 équipant les supports 12 d'un deuxième jeu 11 comportent des fentes 17 exclusivement borgnes. Le pas £1 séparant les fentes borgnes 16 des peignes 13 équipant le premier jeu 10 de supports 12 correspond au multiple du pas P2 des fentes 17 des peignes 14 du deuxième jeu 11 de supports 12, et notamment au double sur l'exemple illustré. On comprendra que le pas £1 des fentes borgnes 16 des peignes 13 équipant le premier jeu 10 de supports 12 correspond au pas des peignes équipant les nacelles de stockage 3, tandis que le pas P2 des fentes 17 des peignes 14 équipant le deuxième jeu 11 de supports 12 correspond au pas des fentes des peignes équipant la nacelle de traitement 4.The illustrated device comprises a transfer head 8 movable along a first rail 9 supported by the frame 7. Referring also to FIG.3, this transfer head 8 supports two sets 10 and 11 of supports 12, each supporting each a comb 13 or 14. The combs 13 or 14 are arranged facing each other for the supports 12 of the same set 10 or 11, in between them a space for the passage of components, as will be described later. Referring also to FIGS. 4 and 5, the combs 13 equipping the supports 12 with a first set 10 comprise open slots 15 and blind slots 16, whereas the combs 14 equipping the supports 12 with a second set 11 comprise slots 17 exclusively blind. The pitch £ 1 separating the blind slots 16 of the combs 13 equipping the first set 10 of supports 12 corresponds to the multiple of the pitch P2 of the slots 17 of the combs 14 of the second set 11 of supports 12, and in particular twice that of the illustrated example. It will be understood that the pitch 1 of the blind slots 16 of the combs 13 equipping the first set 10 of supports 12 corresponds to the pitch of the combs equipping the storage pods 3, whereas the pitch P2 of the slots 17 of the combs 14 equipping the second set 11 of supports 12 corresponds to the pitch of the slots of the combs equipping the treatment nacelle 4.
La tête de transfert 8 est équipée de moyens de réglage discret de l'écartement des supports 12 d'un même jeu 10 ou 11 l'un par rapport à l'autre. Ces dispositions permettent de résoudre un autre problème posé qui réside dans l'adaptation rapide du dispositif au transfert de composants de tailles significativement différentes. Ces moyens de réglage sont du type par brochage. Les supports 12 sont portés à leurs extrémités par la tête de transfert 8 par l'intermédiaire de bras coudés 18, fixés dans leur zone médiane d'inflexion à un organe de transfert 19 agencé en chariot de mobilité de la tête de transfert 8 le long du premier rail 9. Aux extrémités de ces bras coudés 18, sont rapportés des organes de soutien 20 des supports 12 agencés en collier de réception par coulissement de colonnes 21 de guidage des supports 12. Des broches 22, agencées en bouton à double position respectivement de verrouillage et de déverrouillage, coopèrent sélectivement avec une pluralité d'ouvertures ménagées à travers les supports 12 à leurs extrémités.The transfer head 8 is equipped with discrete adjustment means of the spacing of the supports 12 of the same set 10 or 11 relative to each other. These arrangements make it possible to solve another problem that lies in the rapid adaptation of the device to the transfer of components of significantly different sizes. These adjustment means are of the type by broaching. The supports 12 are borne at their ends by the transfer head 8 by means of bent arms 18 fixed in their median zone of inflection to a transfer member 19 arranged in a mobility carriage of the transfer head 8 along of the first rail 9. At the ends of these bent arms 18, there are attached support members 20 of the supports 12 arranged as collars for receiving sliding columns 21 for guiding the supports 12. Pins 22, arranged as double-sided button respectively locking and unlocking, selectively cooperate with a plurality of openings formed through the supports 12 at their ends.
Le dispositif illustré comporte en outre un chariot 23 mobile le long d'un deuxième rail 24 supporté par le bâti 7. En se reportant par ailleurs sur la fig.7, ce chariot 24 supporte une colonne élévatrice 25, porteuse d'une tête de transfert 26 équipée de peignes 27 dont le pas correspond au pas des peignes équipant la nacelle de traitement 4. En se reportant par ailleurs sur la fig.6, le premier châssis 5 est monté sur le bâti 7 de manière mobile en rotation autour d'un axe médian 28. Le premier châssis 5 est agencé pour recevoir en adjacence longitudinale des nacelles de stockage 3 d'un premier jeu, qui sont chargées de composants pour opérer le transfert de ces derniers, et des nacelles de stockage 3 d'un deuxième jeu qui viennent d'être libérées des composants dont elles étaient préalablement chargées, voire des nacelles de stockage 3 en attente de chargement en composants. La mobilité du premier châssis 5 vise à placer alternativement les nacelles de stockage 3 du premier et du deuxième jeu entre une position correspondante d'attente et de déchargement. Sur les fig.8 à fig.16, le dispositif représenté sur les fig.1 et fig.2 est schématisé pour illustrer successivement les modalités de sa mise en œuvre. Sur la fig.8, le dispositif est en position initiale, la nacelle de transfert 26 étant placée sous le premier châssis 5, et plus particulièrement sous une première nacelle de stockage 3 chargée en composants 29 d'un premier paquet.
