Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

L'invention concerne un sous-ensemble 10 d'horlogerie qui comporte, d'une part au moins un composant 1 d'horlogerie en matériau micro-usinable, et d'autre part une coque 20 de protection agencée pour entourer une partie de ce composant 1.The invention relates to a watchmaking subassembly 10 which comprises, on the one hand, at least one watchmaking component 1 made of micro-machinable material, and on the other hand a protective shell 20 arranged to surround a part of this component 1.

Par matériau micro-usinable on entend assez largement tout matériau permettant d'obtenir des composants d'horlogerie en silicium, oxyde de silicium, DLC, matériau amorphe, céramique, ou similaire, et notamment par la mise en oeuvre de procédés tels que « MEMS » ou « LIGA » maintenant bien connus de l'homme du métier. Des progrès considérables ont pu être réalisés en horlogerie, en raison des caractéristiques particulièrement avantageuses des composants réalisés avec de tels procédés dans ces matériaux : reproductibilité parfaite, haute précision géométrique, bonne caractéristiques élastiques durables dans le temps, et la réalisation de composants de très petites dimensions est désormais possible de façon répétitive. Notamment la confection de ressorts-spiraux, d'ancres, de roues d'échappement, de sautoirs, de balanciers, est bien dominée. Ces technologies permettent aussi la réduction du nombre de composants d'un ensemble, car elles se prêtent bien à la réalisation de composants monolithiques comportant des liaisons flexibles, des articulations, des éléments suspendus, ou similaire. La réalisation de composants de types entièrement nouveaux a aussi été rendue possible: c'est le cas de l'application très particulière, illustrée par les figures, et nullement limitative, à un fil de torsion de section rectangulaire, utilisé comme élément de rappel dans un oscillateur à balancier. Il existe toutefois des limitations de mise en oeuvre, en particulier la difficulté ou l'impossibilité de réaliser des formes en dépouille, et la faible résistance au cisaillement, ce qui limite l'application de tels composants à des fonctions où ils subissent des contraintes en compression, en élongation, ou en torsion. Le maintien de ces composants peut, de ce fait, être malaisé dans certaines configurations.Micro-machinable material is broadly understood to mean any material making it possible to obtain watch components made of silicon, silicon oxide, DLC, amorphous material, ceramic, or the like, and in particular by the implementation of processes such as "MEMS Or "LIGA" now well known to those skilled in the art. Considerable progress has been made in watchmaking, because of the particularly advantageous characteristics of the components made with such processes in these materials: perfect reproducibility, high geometric precision, good elastic characteristics over time, and the production of very small components dimensions is now possible in a repetitive way. Especially the production of springs-springs, anchors, escape wheels, jumpers, rockers, is well dominated. These technologies also make it possible to reduce the number of components of a set, since they lend themselves well to the production of monolithic components comprising flexible links, articulations, suspended elements, or the like. The realization of entirely new-type components has also been made possible: this is the case of the very particular application, illustrated by the figures, and in no way limiting, to a torsion wire of rectangular section, used as a return element in a pendulum oscillator. However, there are limitations of implementation, in particular the difficulty or the impossibility of producing undercut shapes, and the low shear strength, which limits the application of such components to functions where they are subjected to constraints in compression, elongation, or torsion. Maintaining these components can, therefore, be difficult in some configurations.

L'invention se propose en particulier de prévenir tout endommagement des composants micro-usinables lors de leur montage dans un sous-ensemble.The invention proposes in particular to prevent damage to the micro-machinable components during their assembly in a subassembly.

C'est pourquoi l'invention associe un tel composant 1 à une coque 20, au moins partiellement enveloppante, qui a pour but de protéger ce composant 1, et d'encaisser à sa place les efforts présentant un risque de destruction du composant 1. Une telle coque 20 est assimilable à une pince, qui soumet le composant 1 uniquement à des efforts de compression, ce qui ne pose aucun problème.This is why the invention associates such a component 1 with a shell 20, at least partially enveloping, which aims to protect this component 1, and to collect in its place the forces with a risk of destruction of the component 1. Such a shell 20 is similar to a clamp, which submits component 1 only to compression forces, which is no problem.

De préférence, le composant 1 comporte une zone plus largement dimensionnée que les autres, qui est prévue pour son assemblage, et qui est dénommée zone de fixation 2. Si aucune zone ne remplit cette condition, la zone de fixation 2 est tout simplement le tronçon du composant 1 qui est situé dans la zone d'assemblage prévue. Un même composant 1 peut bien sûr comporter plusieurs telles zones de fixation 2, qui peuvent prendre la forme de noyaux .Preferably, the component 1 comprises an area more widely dimensioned than the others, which is provided for its assembly, and which is called fixing zone 2. If no zone fulfills this condition, the fixing zone 2 is simply the section component 1 which is located in the planned assembly area. The same component 1 can of course have several such attachment zones 2, which can take the form of cores.

Par exemple, le composant 1 de la figure 2 comporte en partie médiane une première zone de fixation 2, illustrée plus en détail sur la figure 1, et qui est prévue pour l'accrochage relatif entre un balancier 110 et le composant 1, tel que visible sur la figure 6, et comporte en parties d'extrémité deux noyaux 2 pour l'accrochage et la mise sous tension du fil de torsion que constitue ce composant 1 particulier.For example, component 1 of the figure 2 comprises in the middle part a first fixing zone 2, illustrated in more detail on the figure 1 , and which is provided for the relative hooking between a beam 110 and the component 1, as visible on the figure 6 and comprises in end portions two cores 2 for hooking and energizing the torsion wire constituted by this particular component 1.

Cette zone de fixation 2 comporte elle-même au moins une surface de contact 3 périphérique. Dans une réalisation particulière, la zone de fixation 2 comporte encore au moins une surface de positionnement 4. Parmi les différentes surfaces délimitant la zone de fixation 2, une surface de contact périphérique 3 est une surface de jonction avec la coque 20 qui, selon l'invention, protège le composant 1 en particulier lors de son assemblage. Par exemple, si la zone de fixation 2 est cylindrique, même si cette forme est difficile à obtenir avec les procédés cités plus haut dans l'état actuel de la technologie, la surface de contact périphérique est une surface cylindrique unique. Si la zone de fixation 2 est plate, tel que visible sur les autres figures, il comporte deux surfaces de contact périphérique 3 qui sont de préférence les plus grandes surfaces parallèles et opposées, de part et d'autre de la zone de plus faible épaisseur de cette zone de fixation 2. D'autres formes de la zone de fixation 2 peuvent être réalisables, et requérir des appuis sur plus de deux surfaces: la figure 9 illustre la théorie d'une zone de fixation 2 comportant trois surfaces de contact périphérique 3.This attachment zone 2 itself comprises at least one peripheral contact surface 3. In a particular embodiment, the fastening zone 2 further comprises at least one positioning surface 4. Among the various surfaces delimiting the fastening zone 2, a peripheral contact surface 3 is a joining surface with the shell 20 which, according to invention, protects the component 1 in particular during its assembly. For example, if the fastening zone 2 is cylindrical, even though this shape is difficult to obtain with the methods mentioned above in the current state of the art, the peripheral contact surface is a single cylindrical surface. If the fixing zone 2 is flat, as visible in the other figures, it comprises two peripheral contact surfaces 3 which are preferably the largest parallel and opposite surfaces, on either side of the zone of smaller thickness. of this fastening zone 2. Other forms of the fastening zone 2 may be feasible, and require support on more than two surfaces: the figure 9 illustrates the theory of an attachment zone 2 having three peripheral contact surfaces 3.

La coque 20 est agencée pour maintenir cette zone de fixation 2 dans un logement 5 que comporte la coque 20, selon au moins un degré de liberté.The shell 20 is arranged to maintain this fastening zone 2 in a housing 5 that includes the shell 20, in at least one degree of freedom.

A cet effet, la coque 20 est déformable, à géométrie variable entre une forme dite rétreinte et au moins une forme expansée. Par « rétreinte » on entend la forme contractée de la coque 2 résultant d'une opération de chassage ou similaire. Par « déformable » on entend que cette coque est dimensionnée pour subir sans dommage les déformations, relativement faibles, occasionnées par une opération de chassage ou similaire. Cette coque 2 est conçue pour permettre une introduction facile du composant 1 dans un logement intérieur 5, que comporte cette coque 20, dans une position ouverte correspondant à une forme expansée, laquelle n'est généralement pas unique. La coque 20 est conçue pour être refermée autour de la zone de fixation 2 du composant 1, pendant le passage de la forme expansée à la forme rétreinte où la zone de fixation 2 est maintenu sous pression. Ce passage d'une forme à l'autre comporte une étape d'accostage, qui correspond à un appui simple de la coque 20 sur la zone de fixation 2, sans application d'un effort.For this purpose, the shell 20 is deformable, with a variable geometry between a so-called shrunken shape and at least one expanded form. By "shrinkage" is meant the contracted shape of the hull 2 resulting from a driving operation or the like. By "deformable" is meant that this shell is sized to withstand without damage relatively small deformations, caused by a driving operation or the like. This shell 2 is designed to allow easy introduction of the component 1 in an inner housing 5, that includes the shell 20, in an open position corresponding to an expanded form, which is generally not unique. The shell 20 is designed to be closed around the attachment zone 2 of the component 1, during the passage from the expanded form to the necking form where the fixing zone 2 is kept under pressure. This passage from one form to another comprises a docking step, which corresponds to a simple support of the shell 20 on the attachment zone 2, without the application of a force.

Le rétreint qui suit cet accostage peut provenir d'un effort intrinsèque à la coque 20, comme sur les figures 5 et 9 où des moyens de clipage assurent un effort répercuté sur la zone de fixation 2, ou comme sur la figure 4 où l'élasticité de certaines zones de la coque 20 permet à la fois d'assurer son maintien en position fermée, et d'exercer un effort de pression sur la zone de fixation 2.The shrinkage that follows this berthing may come from an intrinsic effort on the hull 20, as on the figures 5 and 9 where clipping means provide a force echoed on the attachment zone 2, or as on the figure 4 where the elasticity of certain zones of the shell 20 makes it possible both to maintain it in the closed position and to exert a pressure force on the fastening zone 2.

Ce rétreint peut aussi être imposé par une interaction avec un composant externe, qui vient comprimer la coque 20 autour de la zone de fixation 2. C'est le cas de la figure 7 où la coque 20 est une pince expansible, du type bien connu en équipement de machine-outil, maintenue à force dans un alésage 112. Il en est de même pour la figure 6, où c'est l'introduction de la coque 20, contenant le composant 1, dans un alésage 112 que comporte un composant récepteur 110, ici un balancier, qui assure l'application d'un effort centripète sur la coque 20, qui transmet un effort de pression à la zone de fixation 2 qui est ainsi fermement maintenue.This shrinkage can also be imposed by an interaction with an external component, which compresses the shell 20 around the attachment zone 2. This is the case of the figure 7 where the shell 20 is an expandable clamp, of the type well known in machine tool equipment, held by force in a bore 112. It is the same for the figure 6 , where it is the introduction of the shell 20, containing the component 1, in a bore 112 that comprises a receiving component 110, here a balance, which ensures the application of a centripetal force on the shell 20, which transmits a pressure force to the fastening zone 2 which is thus firmly maintained.

D'autres formes de réalisation peuvent naturellement être retenues selon la configuration géométrique particulière des composants à maintenir ensemble.Other embodiments may naturally be selected according to the particular geometrical configuration of the components to be held together.

L'invention concerne encore un ensemble 100 d'horlogerie, comportant au moins un composant récepteur 110 et au moins un tel sous-ensemble 10.The invention also relates to a watchmaking assembly 100 comprising at least one receiving component 110 and at least one such subassembly 10.

Le composant récepteur 110 comporte une chambre réceptrice 111 pour chaque sous-ensemble 10. Et la surface intérieure 112 de chaque chambre réceptrice 111 est agencée pour recevoir une surface extérieure 26 que comporte chaque coque 20 correspondante de chaque sous-ensemble 10.The receiving component 110 comprises a receiving chamber 111 for each subassembly 10. And the inner surface 112 of each receiving chamber 111 is arranged to receive an outer surface 26 that comprises each corresponding shell 20 of each subassembly 10.

Avantageusement, au moins une surface intérieure 112 d'une chambre réceptrice 111 est dimensionnée pour comprimer la surface extérieure 26 de la coque 20 correspondante lors de l'insertion du sous-ensemble 10 correspondant dans la chambre réceptrice 111, pour faire passer la coque 20 de sa forme expansée à sa forme rétreinte lors de cette insertion.Advantageously, at least one inner surface 112 of a receiving chamber 111 is sized to compress the outer surface 26 of the corresponding shell 20 during insertion of the corresponding subassembly 10 into the receiving chamber 111, to pass the shell 20 from its expanded form to its narrowed shape during this insertion.

Pour revenir au cas particulier des figures 1 à 4, le composant récepteur 110 est un balancier, et le composant 1 est un fil de torsion. L'invention fournit une bonne solution pour assembler une pièce en silicium dans une pièce métallique. Dans ce cas, la partie à assembler, constituant la zone de fixation 2, est une plaquette sensiblement parallélépipédique. La coque 20 est ici composée de deux demi-lunes, formant le premier élément 21 et le deuxième élément 22, et qui viennent enrober la plaquette en silicium de la zone de fixation 2. Cette zone de fixation 2 comporte, de part et d'autre et de façon symétrique, deux éléments flexibles 6 : 61, 62, qui permettent de positionner précisément ce noyau 1 dans les demi-lunes 21 et 22. Ces demi-lunes 21 et 22 sont dimensionnées de manière à ce qu'elles se chassent l'une dans l'autre, et elles appliquent à la zone de fixation 2 en silicium uniquement des contraintes de compression. De cette manière, une fois les demi-lunes 21 et 22 assemblées sur le fil 1, le tout se maintient par soi-même et peut être manipulé aisément. Une fois le fil 1 enrobé de cette coque 20 à deux demi-lunes 21 et 22, le tout peut être chassé dans une chambre réceptrice 111, notamment un alésage du balancier 110.To return to the particular case of Figures 1 to 4 the receiving component 110 is a pendulum, and the component 1 is a torsion wire. The invention provides a good solution for assembling a silicon part in a metal part. In this case, the part to be assembled, constituting the attachment zone 2, is a substantially parallelepipedal plate. The shell 20 is here composed of two half-moons, forming the first element 21 and the second element 22, and which encase the silicon wafer of the fixing zone 2. This fixing zone 2 comprises, on the one hand, and on the other another and symmetrically, two flexible elements 6: 61, 62, which allow to precisely position this core 1 in the half-moons 21 and 22. These half-moons 21 and 22 are dimensioned so that they hunt one to the other, and they apply to the fastening zone 2 in silicon only compressive stresses. In this way, once the half-moons 21 and 22 assembled on the wire 1, the whole is maintained by itself and can be handled easily. Once the wire 1 coated with this hull 20 to two half-moons 21 and 22, the whole can be driven into a receiving chamber 111, including a bore of the balance beam 110.

Les moyens de positionnement 4 représentés sur les figures 1 à 4 autorisent un positionnement latéral dans le plan méplat de la zone de fixation 2 par les bras élastiques 61 et 62, et aussi un positionnement axial selon la direction du fil 1, par des appuis 63 et 64 que comporte la zone de fixation 2, et qui sont agencés pour coopérer avec des surfaces 65 et 66 correspondantes du premier élément 21, tel que visible sur la figure 3. Ces appuis 63 et 64 peuvent comporter des éléments flexibles afin d'assurer un positionnement précis.The positioning means 4 represented on the Figures 1 to 4 allow lateral positioning in the flat plane of the attachment zone 2 by the elastic arms 61 and 62, and also axial positioning in the direction of the wire 1, by supports 63 and 64 that includes the fixing zone 2, and are arranged to cooperate with corresponding surfaces 65 and 66 of the first element 21, as visible on the figure 3 . These supports 63 and 64 may comprise flexible elements to ensure accurate positioning.

La figure 8 résume un autre positionnement simple, dans lequel la zone de fixation 2 comporte un alésage 7, agencé pour coopérer avec un tourillon ou une goupille 33 que comporte la surface complémentaire principale 31. La configuration inverse est naturellement réalisable.The figure 8 summarizes another simple positioning, wherein the attachment zone 2 comprises a bore 7, arranged to cooperate with a pin or a pin 33 that comprises the main complementary surface 31. The reverse configuration is naturally achievable.

Le procédé d'assemblage peut être résumé ainsi :

  • le composant 1 en matériau micro-usinable, notamment du silicium, est enveloppé d'un composant intermédiaire constitué par une coque 20, puis le tout est chassé dans un composant récepteur 110. Le composant 1 ne perçoit du chassage qu'une contrainte de compression, mais pas de frottement ou de déplacement ;
  • le composant 1 peut comporter des éléments de guidage, permettant d'obtenir un positionnement précis ;
  • le ou les composants intermédiaires, ici les deux demi-lunes 21 et 22, peuvent former un sous-ensemble 10 autoporteur, avant d'être chassé dans le composant récepteur 10.
The assembly process can be summarized as follows:
  • the component 1 of micro-machinable material, in particular silicon, is wrapped with an intermediate component consisting of a shell 20, then the whole is driven into a receiving component 110. The component 1 perceives hunting only a compressive stress but no friction or displacement;
  • the component 1 may comprise guide elements, to obtain a precise positioning;
  • the intermediate component or components, here the two half-moons 21 and 22, can form a self-supporting subassembly, before being driven into the receiving component 10.

L'invention concerne encore un mouvement 200 d'horlogerie comportant au moins un tel ensemble 100.The invention also relates to a watch movement 200 comprising at least one such assembly 100.

L'invention concerne encore une montre 300 comportant au moins un tel ensemble 100.The invention also relates to a watch 300 comprising at least one such assembly 100.

Le principe de l'invention est applicable à d'autres configurations de composants, comme par exemple l'assemblage à une structure d'un piton en silicium, ou d'une tige fixe en silicium, ou similaire.The principle of the invention is applicable to other configurations of components, such as for example the assembly to a structure of a silicon stud, or a fixed rod of silicon, or the like.

En somme, grâce à l'invention, un composant en matériau micro-usinable, notamment en silicium, peut être chassé dans un autre élément. L'invention est aussi utilisable pour l'assemblage de certains matériaux fragiles, tels que verre, saphir, ou similaires, ou pour le maintien de micro-composants de très faible épaisseur.In sum, thanks to the invention, a component of micro-machinable material, in particular silicon, can be driven into another element. The invention can also be used for assembling certain fragile materials, such as glass, sapphire, or the like, or for the maintenance of micro-components of very small thickness.
