Definitions

  • the invention relates to a double spiral and its method of manufacture and, more particularly, to a double spiral formed in one piece.
  • the regulating member of a timepiece generally comprises an inertia flywheel called a balance wheel and a resonator called a spiral. These pieces are decisive for the running quality of the timepiece. Indeed, they regulate the movement, that is to say that they control the frequency of the movement.
  • the object of the present invention is to overcome all or part of the aforementioned drawbacks by proposing a double monoblock spiral whose thermo-elastic coefficient can be adjusted and which is obtained by means of a manufacturing process which minimizes the difficulties of 'assembly.
  • the invention relates to a double spiral comprising, made in a layer of silicon-based material, a first spiral spring mounted coaxially on a ferrule, the ferrule having an extension portion projecting from said spiral spring. and which is made in a second layer of silicon-based material characterized in said extending portion is extended in a third layer of silicon-based material coaxially with a second coil spring to form a double monoblock spiral made of silicon-based materials.
  • the invention relates to a timepiece characterized in that it comprises a double spiral according to one of the preceding variants.
  • Process 1 comprises successive steps intended to form at least one type of double monobloc spiral which can be integrally formed of silicon-based materials.
  • the first step 100 is to provide a substrate 3 of the silicon-on-insulator type (also known as the acronym English SOI).
  • the substrate 3 comprises an upper layer 5 and a lower layer 7 each composed of silicon-based material.
  • the substrate 3 is chosen so that the height of the lower layer 7 corresponds to the height of a portion of the final double spiral 21.
  • the upper layer 5 is used as spacing means with respect to the lower layer 7. Consequently, the height of the upper layer 5 will be adapted according to the configuration of the double spiral 21. According to said configuration, the thickness of the upper layer 5 can oscillate, for example, between 10 and 200 microns.
  • cavities 8 and 10 are selectively etched, for example by a deep reactive ion etching process (also known as DRIE), in the upper layer 5 of silicon-based material.

  • the pattern 9 forms the middle part of the ferrule 27 of the double spiral 21.
  • the pattern 9 is substantially circular cylinder-shaped, however, advantageously according to the method 1, the etching on the upper layer 5 leaves no freedom as to the geometry of the pattern 9.
  • it may not necessarily be circular but, for example, elliptical and / or comprise a non-circular inner diameter.
  • a third step 102 an additional layer 11 of silicon-based material is added to the substrate 3.
  • the additional layer 11 is fixed on the upper layer 5 by means of fusion welding of the silicon-based material (also known as acronym SFB). So, step 102 advantageously allows to cover the upper layer 5 by bonding with a very strong adhesion including the upper face of the pattern 9 on the underside of the additional layer 11.
  • the additional layer 11 may, for example, have a thickness similar to that of the lower layer 7.
  • cavities 12 and 14 are selectively etched, for example, by a method of the DRIE type similar to that of step 101, in the additional silicon layer 11. These cavities 12 and 14 make it possible to form two patterns 13 and 15 defining the inner and outer contours of silicon parts of the double spiral 21.
  • the pattern 13 is substantially circular cylinder shaped and the pattern 15 substantially spiral.
  • the etching on the additional layer 11 leaves complete freedom on the geometry of the patterns 13 and 15.
  • the pattern 15 may, for example, have more turns or an open external curve.
  • the pattern 13 made in the additional layer 11 is of similar shape and substantially perpendicular to the pattern 9 made in the upper layer 5.

  • a material bridge 16 is left between the outer curve of the pattern 15 and the remainder of the unetched layer 11.
  • the patterns 13 and 15 being etched at the same time, they therefore form a one-piece part in the additional layer 11.
  • the patterns 13 and 15 respectively form the upper part of the ferrule 27 and the first spiral spring 23 of the double spiral 21.
  • the patterns 13 and 15 etched in the additional layer 11 are connected from below the pattern 13, with a very strong adhesion, above the etched pattern 9 of the upper layer 5. and laterally by the outer curve of the pattern 15 to the additional layer 11.
  • the method 1 may comprise a fifth step 104 of oxidizing at least the pattern 15, that is to say the first spiral spring 23 of the double spiral in order to make it more mechanically resistant and to adjust its thermal coefficient. elastic.

  • the etching in the lower layer 7 leaves complete freedom on the geometry of the patterns 17 and 19.
  • the pattern 19 may, for example, have more turns or an open external curve.
  • the pattern 17 made in the lower layer 7 is of similar shape and substantially perpendicular to the pattern 9 made in the upper layer 5.

  • a material bridge 16 is left between the outer curve of the pattern 19 and the remainder of the unetched layer 7.
  • the patterns 17 and 19 being etched at the same time, they therefore form a single piece in the lower layer 7.
  • the patterns 17 and 19 respectively form the lower part of the ferrule 27 and the second spiral spring 25 of the double spiral 21.
  • a double monoblock spiral 21 integrally formed of silicon-based materials is obtained, as can be seen in FIGS. Figures 10 and 11 . It is therefore understood that there is no longer any problem of assembly because it is directly carried out during the manufacture of the double hairspring 21.
  • the latter comprises a first hairspring 23, a second hairspring 25 which are coaxially connected to the hairspring. one with respect to the other with a single ferrule 27.
  • the ferrule 27 is formed by the three successive patterns 13, 9 and 17 by etching in the respective successive layers 11, 5 and 7. It is thus clear that the median pattern 9 is useful as a spacing means between the first spiral spring 23 and the second spiral spring 25 but also as guiding means of said spiral spring.

  • each spiral spring 23 and 25 may comprise its own number. of turns, its own geometric characteristics close to the ferrule 27, its own winding direction of the turns but also its own curve geometry, especially at its external part.
  • one and / or the other spiral spring 23, 25 may thus comprise an open outer curve to cooperate with a racking system or comprise, on the end of the outer curve, a bead adapted to serve as a fixed attachment point.
  • the ferrule 27 may also comprise dimensions and / or geometries that are uniformly clean or different on at least one of the lower 17, median 9 and / or high 13 portions.
  • the inner diameter may have a complementary shape on all or part of the height of the shell 27.

  • the spiral springs 23 and 25 have the same height, that is to say are etched in layers 7 and 11 of the same thickness and have the same number of turns. They have their ends of external curve points which are angularly offset with respect to the shell of substantially 180 °. Finally, the winding directions of the turns of the spiral springs 23 and 25 are opposite.

It is therefore understood that the double spiral 21 is adapted to receive by its cavities 18, 10 and 12, advantageously, an axis of smaller diameter than is currently manufactured.
  • said axis may be fixed on the inner diameter 18 and / or 10 and / or 12 of the ferrule 27.
