Requirement EP 1 548 524 A1 discloses a similar method for joining a ceramic-based part to a metal-based part.

Résumé de l'inventionSummary of the invention

Le but de la présente invention est de pallier tout ou partie les inconvénients cités précédemment en proposant une pièce d'habillage formée à partir d'une partie comportant un matériau à base de silicium ou de céramique qui est directement soudée par rayonnement électromagnétique sur une autre partie comme, par exemple, un métal ou un alliage métallique.The object of the present invention is to overcome all or part of the disadvantages mentioned above by providing a trim part formed from a part comprising a silicon-based material or ceramic which is directly welded electromagnetic radiation to another part as, for example, a metal or a metal alloy.

A cet effet, selon un premier mode de réalisation, l'invention se rapporte à une pièce d'habillage pour une pièce d'horlogerie comportant une première partie à base de silicium, une deuxième partie à base de métal caractérisée en ce qu'une surface de la première partie est soudée par rayonnement électromagnétique du type laser sur une surface de la deuxième partie afin de les solidariser.For this purpose, according to a first embodiment, the invention relates to a cladding part for a timepiece comprising a first silicon-based part, a second metal-based part characterized in that The surface of the first part is welded with electromagnetic radiation of the laser type on a surface of the second part in order to secure them.

Selon l'invention, la première pièce à base de silicium comporte du silicium monocristallin, du silicium monocristallin dopé, du silicium polycristallin, du silicium polycristallin dopé, du silicium poreux, de l'oxyde de silicium, du quartz, de la silice, du nitrure de silicium ou du carbure de silicium.According to the invention, the first silicon-based part comprises monocrystalline silicon, doped monocrystalline silicon, polycrystalline silicon, doped polycrystalline silicon, porous silicon, silicon oxide, quartz, silica, silicon nitride or silicon carbide.

Selon un deuxième mode de réalisation, l'invention se rapporte à une pièce d'habillage pour une pièce d'horlogerie comportant une première partie à base de céramique, une deuxième partie à base de métal caractérisée en ce qu'une surface de la première partie est soudée par rayonnement électromagnétique du type laser sur une surface de la deuxième partie afin de les solidariser.According to a second embodiment, the invention relates to a trim piece for a timepiece comprising a first ceramic-based portion, a second metal-based portion characterized in that a surface of the first part is welded by electromagnetic radiation of the laser type on a surface of the second part to secure them.

Selon l'invention, la première pièce à base de céramique comporte du verre photostructurable, du borosilicate, de l'aluminosilicate, du verre de quartz, du zerodur, du corindon monocristallin, du corindon polycristallin, de l'alumine, de l'oxyde d'aluminium, du nitrure d'aluminium, du rubis monocristallin, du rubis polycristallin, de l'oxyde de zirconium, de l'oxyde de titane, du nitrure de titane, du carbure de titane, du nitrure de tungstène, du carbure de tungstène, du nitrure de bore ou du carbure de bore.According to the invention, the first ceramic-based part comprises photostructurable glass, borosilicate, aluminosilicate, quartz glass, zerodur, monocrystalline corundum, polycrystalline corundum, alumina, oxide of aluminum, aluminum nitride, monocrystalline ruby, polycrystalline ruby, zirconium oxide, titanium oxide, titanium nitride, titanium carbide, tungsten nitride, carbide tungsten, boron nitride or boron carbide.

Avantageusement selon les deux modes de réalisation de l'invention, on comprend que le soudage direct des surfaces rend sensiblement invisible la solidarisation car le rayonnement électromagnétique agit directement à l'interface entre les deux pièces. Par conséquent, la pièce d'habillage est du type composite sans qu'il soit perceptible comment elle a été obtenue sauf par vérification destructive. Avantageusement selon l'invention, les parties déjà développées peuvent donc être utilisées et désormais solidarisées avec une meilleure adhérence et une garantie de tenue dans le temps plus élevé qu'avec le collage.Advantageously according to the two embodiments of the invention, it is understood that the direct welding of the surfaces makes the joining substantially invisible because the electromagnetic radiation acts directly at the interface between the two parts. Therefore, the dressing is composite type without it being noticeable how it was obtained except by destructive verification. Advantageously according to the invention, the parts already developed can be used and now secured with better adhesion and a guarantee of staying with time higher than with bonding.

Enfin, les parties à base de céramique ou de silicium n'ont pas à avoir de moyens de déformation élastique ou plastique évitant qu'elles soient brisées par un assemblage car le soudage solidarise directement les surfaces des parties à base de céramique ou de silicium contre les surfaces des parties à base de métal. On comprend ainsi l'avantage immédiat dans le domaine de l'horlogerie tant du point de vue de la compacité (pas de volume supplémentaire nécessaire aux moyens de déformation élastique ou plastique) que de la robustesse (soudure matériau - matériau).Finally, the ceramic-based or silicon-based parts do not have to have elastic or plastic deformation means that prevent them from being broken by an assembly because the welding directly affixes the surfaces of the ceramic or silicon-based parts against surfaces metal-based parts. We thus understand the immediate advantage in the field of watchmaking both from the point of view of compactness (no additional volume required for elastic or plastic deformation means) that robustness (welding material - material).

Conformément à d'autres variantes avantageuses des deux modes de réalisation de l'invention :

De plus, l'invention se rapporte à une pièce d'horlogerie caractérisée en ce qu'elle comporte une pièce d'habillage selon l'une des variantes précédentes.In addition, the invention relates to a timepiece characterized in that it comprises a covering part according to one of the preceding variants.

De manière additionnelle, l'invention se rapporte également à un procédé de fabrication d'une pièce d'habillage selon le premier mode de réalisation pour une pièce d'horlogerie comportant les étapes suivantes :

De plus, le rayonnement électromagnétique du type laser offre une grande flexibilité quant à la localisation et la forme (plate, en pente, non rectiligne, etc.) des zones qui doivent être soudées. On comprend ainsi que les parties déjà développées peuvent être utilisées et désormais solidarisées avec une meilleure adhérence et une garantie de tenue dans le temps plus élevé qu'avec le collage.Advantageously according to the two embodiments of the invention, it is understood that the method is simple, fast and that it is not necessary to provide the material to secure the two materials or to apply a force of approximation between the first and second parts.In addition, the laser-type electromagnetic radiation offers great flexibility in the location and shape (flat, sloping, non-straight, etc.) of the areas to be welded. parts already developed can be used and now secured with better adhesion and a guarantee of staying in time higher than with the bonding.

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

Comme expliqué ci-dessus, l'invention se rapporte à une pièce d'habillage formée à l'aide d'une partie dont le matériau ne comporte pas de domaine plastique utilisable, c'est-à-dire avec un domaine plastique très restreint, avec une deuxième partie comportant le même type de matériau ou un autre type de matériau.As explained above, the invention relates to a cladding part formed using a part whose material has no usable plastic field, that is to say with a very plastic field. restricted, with a second part comprising the same type of material or another type of material.

Cette pièce d'habillage a été imaginée pour des applications dans le domaine horloger et est rendue nécessaire par la part croissante que tiennent les matériaux fragiles comme ceux à base de silicium ou de céramique. On peut, à titre d'exemple, envisager de former un boîtier, un cadran, un réhaut, une glace, une lunette, un poussoir, une couronne, un fond de boîtier, une aiguille ou un bracelet totalement ou partiellement à base de matériaux fragiles.This piece of clothing has been designed for applications in the field of watchmaking and is made necessary by the growing share of fragile materials such as those based on silicon or ceramic. It is possible, for example, to form a case, a dial, a flange, an ice, a bezel, a pusher, a crown, a case back, a needle or a bracelet wholly or partially based on materials. fragile.

Toutefois, le fait de toujours pouvoir utiliser des parties habituelles comme, par exemple, les glaces en corindon dont la fabrication est maîtrisée, est une contrainte qui est difficile à concilier avec l'utilisation de parties ne comportant pas de domaine plastique.However, the fact of always being able to use usual parts such as, for example, corundum mirrors whose production is controlled, is a constraint which is difficult to reconcile with the use of parts that do not comprise a plastic field.

C'est pourquoi, selon un premier mode de réalisation, l'invention se rapporte à une pièce d'habillage pour une pièce d'horlogerie comportant une première partie à base de silicium, une deuxième partie à base de métal caractérisée en ce qu'une surface de la première partie est soudée par rayonnement électromagnétique sur une surface de la deuxième partie afin de les solidariser.This is why, according to a first embodiment, the invention relates to a trim piece for a timepiece comprising a first silicon-based part, a second metal-based part characterized in that a surface of the first part is welded by electromagnetic radiation to a surface of the second part to secure them.

Avantageusement selon l'invention, on comprend qu'il n'est pas obligatoire d'apporter de la matière pour solidariser les deux parties comme pour le collage ou l'utilisation d'une partie intermédiaire. Ainsi, à titre d'exemple, un simple trou permettant de coopérer avec un boîtier de section correspondante est suffisant, le trou étant formé dans la première partie ou dans la deuxième partie.Advantageously according to the invention, it is understood that it is not mandatory to provide the material to secure the two parts as for gluing or the use of an intermediate portion. Thus, for example, a simple hole for cooperating with a housing of corresponding section is sufficient, the hole being formed in the first part or in the second part.

On comprend donc que les parties déjà développées peuvent être utilisées et désormais soudées par rayonnement électromagnétique avec une meilleure adhérence et une garantie de tenue dans le temps plus élevée qu'avec un collage. Enfin, le soudage direct des surfaces rend sensiblement invisible la solidarisation. En effet, il suffit que l'une des première et deuxième parties soit opaque et, une autre, transparente à la longueur d'onde dudit rayonnement électromagnétique pour souder lesdites surfaces des première et deuxième parties lorsqu'elles sont l'une contre l'autre. Un tel soudage par rayonnement électromagnétique du type laser est, par exemple, expliqué dans le document EP 1 436 830 incorporé par référence dans la présente description. De plus, comme expliqué dans le document EP 1 436 830 , si les première et deuxième pièces sont transparentes à la longueur d'onde dudit rayonnement électromagnétique du type laser, de manière optionnelle, un matériau intermédiaire destiné à favoriser la solidarisation entre les deux matériaux peut être utilisé. Ainsi, ce matériau intermédiaire forme une couche destinée à induire un échauffement suffisamment intense pour générer la fusion des deux matériaux.It is therefore understood that the already developed parts can be used and now welded by electromagnetic radiation with better adhesion and a guarantee of staying with time higher than with a collage. Finally, the direct welding of the surfaces makes the fastening substantially invisible. Indeed, it is sufficient that one of first and second portions are opaque and another transparent to the wavelength of said electromagnetic radiation for welding said surfaces of the first and second portions when they are against each other. Such welding by electromagnetic radiation of the laser type is, for example, explained in the document EP 1 436 830 incorporated by reference in the present description. In addition, as explained in the document EP 1 436 830 if the first and second pieces are transparent to the wavelength of said laser-type electromagnetic radiation, optionally an intermediate material for promoting bonding between the two materials may be used. Thus, this intermediate material forms a layer intended to induce a sufficiently intense heating to generate the melting of the two materials.

Selon le premier mode de réalisation, la première partie à base de silicium comporte, de manière préférée, du silicium monocristallin, du silicium monocristallin dopé, du silicium polycristallin, du silicium polycristallin dopé, du silicium poreux, de l'oxyde de silicium, du quartz, de la silice, du nitrure de silicium ou du carbure de silicium. De plus, la première partie à base de silicium peut en outre comporter optionnellement au moins un revêtement partiel d'oxyde de silicium, de nitrure de silicium, de carbure de silicium ou d'un allotrope du carbone suivant les applications prévues de la pièce d'habillage.According to the first embodiment, the first silicon-based part preferably comprises monocrystalline silicon, doped monocrystalline silicon, polycrystalline silicon, doped polycrystalline silicon, porous silicon, silicon oxide, quartz, silica, silicon nitride or silicon carbide. In addition, the first silicon-based portion may further optionally comprise at least one partial coating of silicon oxide, silicon nitride, silicon carbide or a carbon allotrope according to the intended applications of the part of silicon. dressing.

Selon un deuxième mode de réalisation, l'invention se rapporte à pièce d'habillage pour une pièce d'horlogerie comportant une première partie à base de céramique, une deuxième partie à base de métal caractérisée en ce qu'une surface de la première partie est soudée par rayonnement électromagnétique sur une surface de la deuxième partie afin de les solidariser.According to a second embodiment, the invention relates to a covering part for a timepiece comprising a first ceramic-based part, a second metal-based part characterized in that a surface of the first part is welded by electromagnetic radiation to a surface of the second part to secure them.

Avantageusement selon l'invention, on comprend qu'il n'est pas obligatoire d'apporter de la matière pour solidariser les deux parties comme pour le collage ou l'utilisation d'une partie intermédiaire. Ainsi, à titre d'exemple, un simple trou permettant de coopérer avec une glace de section correspondante est suffisant, le trou étant formé dans la première partie ou dans la deuxième partie.Advantageously according to the invention, it is understood that it is not mandatory to provide the material to secure the two parts as for gluing or the use of an intermediate portion. So, as a for example, a simple hole for cooperating with an ice of corresponding section is sufficient, the hole being formed in the first part or in the second part.

On comprend donc que les parties déjà développées peuvent être utilisées et désormais soudées par rayonnement électromagnétique avec une meilleure adhérence et une garantie de tenue dans le temps plus élevée qu'avec un collage. Enfin, le soudage direct des surfaces rend sensiblement invisible la solidarisation. En effet, il suffit que l'une des première et deuxième parties soit opaque et, une autre, transparente à la longueur d'onde dudit rayonnement électromagnétique pour souder lesdites surfaces des première et deuxième parties lorsqu'elles sont l'une contre l'autre. Un tel soudage par rayonnement électromagnétique du type laser est, par exemple, expliqué dans le document EP 1 436 830 incorporé par référence dans la présente description. De plus, comme expliqué dans le document EP 1 436 830 , si les première et deuxième pièces sont transparentes à la longueur d'onde dudit rayonnement électromagnétique du type laser, de manière optionnelle, un matériau intermédiaire destiné à favoriser la solidarisation entre les deux matériaux peut être utilisé. Ainsi, ce matériau intermédiaire forme une couche destinée à induire un échauffement suffisamment intense pour générer la fusion des deux matériaux.It is therefore understood that the already developed parts can be used and now welded by electromagnetic radiation with better adhesion and a guarantee of staying with time higher than with a collage. Finally, the direct welding of the surfaces makes the fastening substantially invisible. Indeed, it suffices that one of the first and second parts is opaque and another transparent to the wavelength of said electromagnetic radiation to weld said surfaces of the first and second parts when they are one against the other. Such welding by electromagnetic radiation of the laser type is, for example, explained in the document EP 1 436 830 incorporated by reference in the present description. In addition, as explained in the document EP 1 436 830 if the first and second pieces are transparent to the wavelength of said laser-type electromagnetic radiation, optionally an intermediate material for promoting bonding between the two materials may be used. Thus, this intermediate material forms a layer intended to induce a sufficiently intense heating to generate the melting of the two materials.

Selon le deuxième mode de réalisation, la première partie à base de céramique comporte, de manière préférée, du verre photostructurable, du borosilicate, de l'aluminosilicate, du verre de quartz, du zerodur, du corindon monocristallin, du corindon polycristallin, de l'alumine, de l'oxyde d'aluminium, du nitrure d'aluminium, du rubis monocristallin, du rubis polycristallin, de l'oxyde de zirconium, de l'oxyde de titane, du nitrure de titane, du carbure de titane, du nitrure de tungstène, du carbure de tungstène, du nitrure de bore ou du carbure de bore. De plus, la première partie à base de céramique peut en outre comporter optionnellement au moins un revêtement partiel d'oxyde de silicium, de nitrure de silicium, de carbure de silicium ou d'un allotrope du carbone suivant les applications prévues de la pièce d'habillage.According to the second embodiment, the first ceramic-based portion preferably comprises photostructurable glass, borosilicate, aluminosilicate, quartz glass, zerodur, monocrystalline corundum, polycrystalline corundum, aluminum oxide, alumina, aluminum oxide, aluminum nitride, monocrystalline ruby, polycrystalline ruby, zirconium oxide, titanium oxide, titanium nitride, titanium carbide, tungsten nitride, tungsten carbide, boron nitride or boron carbide. In addition, the first ceramic-based portion may further optionally comprise at least one partial coating of silicon oxide, silicon nitride, silicon carbide or a carbon allotrope according to the intended applications of the trim piece.

Selon les deux modes de réalisation, la deuxième partie comporte préférentiellement un alliage de fer comme de l'acier 15P, 20AP ou 316L, un alliage de cuivre comme du laiton, un alliage de nickel comme du maillechort, du titane ou un de ses alliages, de l'or ou un de ses alliages, de l'argent ou un de ses alliages, du platine ou un de ses alliages, du ruthénium ou un de ses alliages, du rhodium ou un de ses alliages ou du palladium ou un de ses alliages.According to the two embodiments, the second part preferably comprises an iron alloy such as 15P, 20AP or 316L steel, a copper alloy such as brass, a nickel alloy such as nickel silver, titanium or one of its alloys , gold or one of its alloys, silver or one of its alloys, platinum or one of its alloys, ruthenium or one of its alloys, rhodium or any of its alloys or palladium or one of its alloys its alloys.

Selon les deux modes de réalisation de l'invention, la première partie et/ou la deuxième partie peuvent former une grande variété de pièces d'habillage pour une pièce d'horlogerie. A titre d'exemples nullement limitatifs et en relation avec la figure 1, la première partie et/ou la deuxième partie peuvent ainsi former notamment un boîtier 1 comme la carrure 2 et les cornes 3, un cadran 4, un réhaut, une lunette 5, un poussoir 6, une couronne 7, un fond 8 de boîtier, une aiguille 9, un bracelet 10 comme un maillon 11, un décor 12, une applique 13, une glace 14, un fermoir, un pied de cadran, une tige de couronne ou une tige de poussoir.According to the two embodiments of the invention, the first portion and / or the second portion can form a wide variety of trim parts for a timepiece. As non-limiting examples and in relation to the figure 1 the first part and / or the second part can thus form in particular a housing 1 such as the middle part 2 and the horns 3, a dial 4, a flange, a bezel 5, a pusher 6, a crown 7, a bottom 8 of the housing , a needle 9, a bracelet 10 as a link 11, a decoration 12, a wall 13, an ice 14, a clasp, a dial foot, a crown rod or a push rod.

A titre d'exemple, la figure 2 présente une pièce d'habillage 21 formant un cadran 22. Le corps du cadran 22 comporte plusieurs appliques 23, 24 formant par exemple un tour d'heures, un décor 25 pouvant, par exemple, représenter une marque de fabrique et plusieurs pieds 26, 27 de cadran permettant de fixer le cadran 22 à une pièce d'horlogerie.For example, the figure 2 has a dressing part 21 forming a dial 22. The body of the dial 22 comprises a plurality of sconces 23, 24 forming for example a round of hours, a decor 25 may, for example, represent a trademark and several feet 26, 27 of dial for fixing the dial 22 to a timepiece.

On comprend donc, par exemple, que le cadran 22 peut directement être soudé par rayonnement électromagnétique tel qu'un laser au niveau de ses surfaces de contacts 28, 29, 30, 31, 32 avec les appliques 23, 24 et/ou le décor 25 et/ou les pieds 26, 27. Il suffit que, soit le cadran 22, soit les appliques 23, 24 et/ou le décor 25 et/ou les pieds 26, 27, soit transparent à la longueur d'onde dudit rayonnement électromagnétique pour souder les surfaces en contact. Bien entendu, d'autres types de surface de contact peuvent être prévus comme des surfaces en pente ou des surfaces non rectilignes.It is thus understood, for example, that the dial 22 can be directly welded by electromagnetic radiation such as a laser at its contact surfaces 28, 29, 30, 31, 32 with the appliques 23, 24 and / or the decoration 25 and / or the feet 26, 27. It suffices that either the dial 22, or the appliques 23, 24 and / or the decor 25 and / or the feet 26, 27, is transparent to the wavelength of said radiation. electromagnetic for welding the surfaces in contact. Of course, other types of contact surface may be provided as sloping surfaces or non-rectilinear surfaces.

La présente invention ne se limite pas à l'exemple illustré mais est susceptible de diverses variantes et modifications qui apparaîtront à l'homme de l'art. En particulier, la deuxième partie peut être d'un autre type de matériau qu'un métal ou un alliage métallique. Ainsi, de manière non limitative, la deuxième partie peut également être en un même matériau que la première partie, en céramique ou en un matériau semi-conducteur.The present invention is not limited to the illustrated example but is susceptible of various variations and modifications that will occur to those skilled in the art. In particular, the second part may be of another type of material than a metal or a metal alloy. Thus, without limitation, the second part may also be of the same material as the first part, ceramic or a semiconductor material.

Toutefois, dans ce cas, comme expliqué dans le document EP 1 436 830 , si les première et deuxième pièces sont transparentes à la longueur d'onde dudit rayonnement électromagnétique du type laser, de manière optionnelle, un matériau intermédiaire destiné à favoriser la solidarisation entre les deux matériaux, doit être utilisé. En effet, ce matériau intermédiaire formerait alors une couche destinée à induire un échauffement suffisamment intense pour générer la fusion des deux matériaux transparents à la longueur d'onde dudit rayonnement électromagnétique.However, in this case, as explained in the document EP 1 436 830 if the first and second pieces are transparent to the wavelength of said laser-type electromagnetic radiation, optionally an intermediate material for promoting bonding between the two materials should be used. Indeed, this intermediate material would then form a layer intended to induce heating sufficiently intense to generate the fusion of the two transparent materials at the wavelength of said electromagnetic radiation.

Comme expliqué ci-dessus, la première partie et/ou la deuxième partie peuvent former une variété de pièces d'habillage. A titre d'exemples additionnels à la figure 2, le boîtier 1 pourrait être formé à partir d'une première partie formant la carrure 2 et de plusieurs deuxièmes parties formant les cornes 3 ou le bracelet 10 pourrait être formé à partir de plusieurs premières parties formant plusieurs maillons 11 chaque première partie étant solidarisée à plusieurs deuxièmes parties formant des décors.As explained above, the first portion and / or the second portion may form a variety of trim pieces. As additional examples to the figure 2 , the housing 1 could be formed from a first part forming the middle part 2 and several second parts forming the horns 3 or the bracelet 10 could be formed from several first parts forming several links 11 each first part being secured to several second parts forming decorations.

De plus, une première partie pourrait former une glace 14 et être solidaire d'une deuxième partie formant une lunette 5, une première partie pourrait former un poussoir 6 et être solidaire d'une deuxième partie formant une tige de poussoir, une première partie pourrait former une couronne 7 et être solidaire d'une deuxième partie formant une tige de couronne, une première partie pourrait former un fond 8 de boîtier et être solidaire d'une deuxième partie formant une glace destinée à montrer le mouvement horloger, une première partie pourrait former un maillon d'attache de bracelet et être solidaire d'une deuxième partie formant un fermoir ou encore une première partie pourrait former un maillon 11 de bracelet et être solidaire d'une deuxième partie formant un contre-maillon.In addition, a first part could form a lens 14 and be integral with a second part forming a bezel 5, a first part could form a pusher 6 and be integral with a second part forming a push rod, a first part could form a ring 7 and be integral with a second portion forming a crown rod, a first portion could form a bottom 8 of the housing and be secured to a second portion forming an ice to show the watch movement, a first part could form a bracelet attachment link and be secured to a second part forming a clasp or a first part could form a bracelet link 11 and be integral with a second part forming a counter link.

Enfin, ledit au moins un revêtement partiel optionnel se saurait se limiter à de l'oxyde de silicium, de nitrure de silicium, du carbure de silicium ou un allotrope du carbone. Ainsi, suivant les applications prévues de la pièce d'habillage, d'autres matériaux peuvent être envisagés pour, par exemple, améliorer les qualités tribologiques, thermiques ou visuelles de la pièce d'habillage. A titre d'exemple, au moins un revêtement partiel antireflet peut être déposé.Finally, said at least one optional partial coating is not limited to silicon oxide, silicon nitride, silicon carbide or an allotrope of carbon. Thus, according to the intended applications of the covering part, other materials may be envisaged to, for example, improve the tribological, thermal or visual qualities of the dressing room. By way of example, at least one partial antireflection coating may be deposited.
