Definitions

  • the present invention relates to a method of assembling a brittle component on a metal part, as well as components assembled according to this method. More particularly, the present invention relates to the assembly of a micromechanical part, in particular the watch, according to the aforementioned method.
  • the present invention therefore aims to provide a new method of assembling fragile components that does not have these disadvantages of known assemblies and which is also particularly suitable for use in the field of timepieces.
  • the object of the present invention is to provide a method of assembling fragile components, especially for the watch industry, which can be used to assemble parts made of materials that break easily without debris.
  • the subject of the invention is a process for assembling fragile components according to claim 1 and a micromechanical part assembled using this method according to claim 11.
  • the various embodiments with the particularly advantageous solutions are defined in the dependent claims.
  • the board (1) will have the characteristic of having a central hole not round but having a shape for subsequent galvanic growth.
  • the shape in the case shown is composed of a substantially circular central portion and 6 cells (AI) of substantially semicircular shape. This structure can be more easily observed at Figures 3 to 6 . Obviously, the structure of the central hole of the board (1) can also vary.
  • the method according to the present invention therefore consists of the following steps:
  • the next step, represented at figure 3 consists in covering all the components of the part with an insulating material.
  • the material typically used is parylene because its deposition is consistent on the parts.
  • Parylene is a biocompatible polymer film which is deposited under vacuum after evaporation and transformation of its precursor. The properties and handling of parylene are well known to those skilled in the art so that a detailed description is not necessary.
  • the parylene is removed on the surface of the shaft (2).
  • the parylene layer (3) is removed mechanically by rotation of the board (1).
  • a mechanical or laser ablation solution can also be considered with similar results.
  • the figure 4 represents the surfaces (4) of the axis (2) stripped of their parylene.
  • a fine galvanic growth (5) typically greater than 2 microns ( ⁇ m) is then performed on the axis (2), in other words, on the surfaces (4) released from the parylene layer (3).
  • the other parts of the assembly being protected by this insulating layer (3) no growth will occur on these parts coated with parylene (3). This explains the use of the name "selective growth”.
  • This step of the process according to the present invention is represented at figure 5 .
  • This growth (5) will take place in the cells (AI) and prevent any rotation between the board (1) and the axis (3).
  • the radial displacement will also be prevented by the growth of the metal (5) at the edge of the board (1). If the wheel does not press against a span one can consider the growth (5) on both edges.
  • the board (1) being locked in rotation and in axial displacement, it is thus blocked.
  • the insulating material (3) is removed from all the surfaces of the room.
  • the assembly process of the part is completed.
