Abstract:
Determined is a correlation value R (=I(t)/I(0)) between an intensity I(0) of monitor light at least at one specific wavelength which is detected before cure of resin RSN and an intensity I (t) of the monitor light at the specific wavelength which is thereafter detected, and the cure of the resin RSN is judged to be completed when a temporal change of the correlation value R comes to a stable state. In assembly manufacturing, light-cure resin RSN is interposed between at least two members M1 and M2. After the above described cure end point is detected, application of resin curing light to the resin RSN is stopped, and the assembly is transferred.
Abstract:
The correlation R=I(t)/I(0) between the intensity I(0) of at least one specific wavelenght of monitoring light measured before a resin RSN is cured and the Intensity (t) of the specific wavelenght after the resin RSN is cured is determined. When the variation with time of the correlation R becomes stable, it is judged that the curing of the resin RSN has ended. To produce an assembly, a photocuring resin RSN is interposed between at least two members (M1, M2). When the curing end point is detected, the irradiation of the resin RSN with resin-curing light is stopped, and the assembly is transferred.
