Definitions

  • the present invention relates to tool holders.
  • the present invention relates to a tool holder arranged to improve positioning of a tool.
  • An induction heating device typically comprises a coil, local to or remote from the induction heating device, arranged to induce heating in a susceptor.
  • the susceptor typically comprises an electrically-conductive material, for example a metal, that absorbs electromagnetic energy from the induction heating device and may be used to heat an electrical insulator, for example a polymer.
  • the coil is positioned closely spaced-apart from the susceptor, in alignment with the susceptor, for example coaxially or concentrically, and parallel to the susceptor.
  • the coil may provide the desired heating effect, for example the susceptor may be heated, for example uniformly heated.
  • the susceptor is a coated susceptor, for example having a coating comprising a heat-activated adhesive or film, arranged to provide coupling, for example adhering, bonding or welding, between the susceptor and another part proximal to and/or in contact with the coating.
  • the another part may be, for example, a membrane comprising a polymeric composition comprising a polymer.
  • Relatively thin and/or sensitive coatings may be damaged by incorrect heating, compromising an integrity and/or a uniformity of a coupling to the another part.
  • induction heating of susceptors comprising such coatings may require relatively more accurate and/or precise positioning of a coil of an induction heating device, for example in 1 , 2 or 3 planes and/or orientations.
  • the coil may be positioned over the susceptor, for example partly or completely over the susceptor and thereby, partly and/or completely hiding, covering or concealing the susceptor. That is, the susceptor may not be visible.
  • a user may manually position the coil according to a movement of the coil relatively distal the susceptor.
  • the coil may be positioned proximal the ground while the user may stand on the ground during use. That is, the accuracy and/or precision of manual positioning of the coil by the user may be reduced.
  • the another part may overlay the susceptor partly and/or completely, and thereby, partly and/or completely hiding, covering or concealing the susceptor, which may be additionally and/or alternatively embedded or recessed in a substrate. That is, the susceptor may not be visible and/or apparent. Hence, the accuracy and/or precision of the manual positioning of the coil by the user may be reduced, whereby heating of the susceptor may be non-uniform. The non-uniform heating may thus reduce the integrity and/or the uniformity of the coupling of the coated susceptor to the another part. The integrity and/or the uniformity of the coupling may not be readily determined and may become first apparent during premature failure of the coupling.

  • a mount coupled to the member, wherein the mount comprises a coupling arranged to receive the tool
  • the tool holder is arranged to move from the first configuration to the second configuration by a displacement of the handle
  • the displacement of the mount is less than the displacement of the handle; and wherein the mount is arranged to permit the tool to move, relative to the foot, in a direction transverse to the plane, while remaining parallel to the plane P.

  • the tool holder permits the coil to be translated by the displacement of the mount in the plane parallel to the membrane to the second configuration. During the translation, the coil may remain spaced apart from the membrane by the spacing.
  • the coil is arranged parallel to the membrane in the second, translated configuration.
  • the mount is arranged to permit the coil to move, relative to the foot, in the direction transverse to the plane, while remaining parallel to the plane P, such that the coil may be spaced relatively more proximal the membrane by a smaller spacing, for example the coil may contact the membrane.
  • Movement of the tool holder from the first configuration to the second configuration is by the displacement of the handle. Since the displacement of the mount is less than the displacement of the handle, an accuracy and/or precision of positioning the coil may be improved, compared with a direct translation of the coil. By improving the accuracy and/or the positioning of the coil relative to the susceptor, the tool holder provides for more uniform heating of the susceptor by the coil.
