Abstract
A fabrication procedure for crystal resonators in which belted component holders are used, each accomodating the constituent elements of a resonator. When the above-mentioned elements are assembled, the component holders serve the purpose of assembly fixtures. The assembled resonators are retained in the component holders which thus also provide a packaging function for the final products. The component holders have elastically deformable clamps which accomodate the constituent elements of the resonators to be assembled and have support sections which receive the crystal element of each resonator.
Claims10
A device for assembling crystal resonators at an assembly station, each resonator being formed of constituent elements including a crystal, the device comprising:
- a plurality of component holders, each holder being provided with means for receiving said constituent elements, said means for receiving including elastically deformable jaws between which the constituent elements may be enaged;
- means for accurately positioning and indexing said component holders at said assembly station;
- and
- means for joining the individual component holders together in series.
A method for assembling and packaging crystal resonators at an assembly station, each resonator being formed of constituent elements including a crystal comprising the steps of
- engaging the constituent elements of the crystal resonators between elastically deformable jaws of component holders forming blocks hinged in chains, said holders positioning said elements at the assembly station;
- connecting at least some of said elements together;
- adjusting the frequency of the crystals;
- encapsulating the resonators;
- removing the blocks of component holders from the assembly station;
- and
- storing said crystal resonator in said component holders.
