Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
79 words
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.
Claim 2
Independent Claim
79 words
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.
Claim 3
Dependent Claim
28 words
The device as claimed in claim 1 in which at least one of said elastically deformable jaws provides for a translational displacement of the constituent element gripped thereby.
Claim 4
Dependent Claim
48 words
The device as claimed in claim 1 wherein the component holders each have a support section for accomodating the crystal of each of the resonators, said support section including two elastically deformable parts configured in such a manner that they can be spread apart to free the crystal.
Claim 5
Dependent Claim
32 words
The device as claimed in claim 3 wherein the commponent holders include holes to provide for the passage therethrough at suitable locations of a laser beam utilized for adjusting the resonator frequency.
Claim 6
Dependent Claim
28 words
The device as claimed in claim 1 wherein the means for indexing the component holders include means for advancing the component holder and for positioning each holder individually.
Claim 7
Dependent Claim
37 words
The device as claimed in claim 1 wherein at least portions of the component holders are arranged for accomodating the assembled resonators and so that the holders may be used as a packaging element for the resonators.
Claim 8
Dependent Claim
30 words
The device as claimed in claim 1 wherein some of said means for joining the component holders together rigidly join the component holders together to form blocks of individual holders.
Claim 9
Dependent Claim
23 words
The device as claimed in claim 1 wherein some of said means for joining the component holders together are flexible to form chains.
Claim 10
Dependent Claim
39 words
The device as claimed in claim 7 or 8 wherein some of said means for joining are rigid and some are flexible so that the individual component holders form blocks of component holders hinged flexibly together to form chains.
Claim 11
Independent Claim
91 words
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.
Claim 12
Independent Claim
91 words
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.
