Abstract
A method and an apparatus for fixing a part and a part support for mounting the part by use of adhesive via an intermediate member are disclosed. The adhesive is implemented by photocuring adhesive while the intermediate member is formed of a material transparent for light. The intermediate member is free from coloring and deformation when illuminated by light for curing the adhesive. The adhesive is prevented from dropping or turning round to other portions during assembly.
Claims31
A method of fixing a part and a part support for mounting said part by use of photocuring adhesive via an intermediate member formed of resin transparent for light, said method comprising the steps of:
- radiating light for curing the adhesive;
- and
- cutting a part of the light lying in a wavelength range causing a property of the intermediate member to change.
A method as claimed in claim, wherein the part of the light to be cut is UV (Ultra Violet) rays lying in a short wavelength range.
An apparatus for fixing a part and a part support for mounting said part via an intermediate member formed of resin transparent for light and contacting said part and said part support, said apparatus comprising:
- applying means for applying photocuring adhesive to interfaces between said part, said part support and said intermediate member;
- radiating means for radiating light to said interfaces via said intermediate member;
- and
- a bandpass filter positioned on an optical path for the light for cutting a part of said light lying in a wavelength range causing a property of the intermediate member to change.
A method of fixing a part and a part support for mounting said part via an intermediate member by using adhesive said method comprising the steps of:
- positioning the intermediate member between the part and the part support;
- applying adhesive to a substantially vertical first interface and a substantially horizontal second interface between the part and the part support end the intermediate member;
- causing pressing meant to press the intermediate member against the part and the part support;
- and
- causing the adhesive applied to said first interface and raid interface to spread.
An apparatus for fixing a part and a part support for mounting said part by using adhesive with the intermediary of an intermediate member provided between said part and said part support, said apparatus comprising:
- part support holding means for positioning and holding the part support at a preselected assembling position;
- part supporting means for supporting the part in a position adjustable relative to the part support held by said part support holding means;
- position detecting means for detecting a position of the part supported by said part supporting means;
- position adjusting means for adjusting, based on the position detected by said position detecting means, a position in which the part should be mounted to the part support held by said part support holding means;
- adhesive applying means for applying the adhesive to a substantially vertical first interface and a substantially horizontal second interface between the part and the intermediate member and between the part support and said intermediate member;
- and
- pressing means for pressing the intermediate member against the part and the part support to thereby cause the adhesive applied to said first interface and said second interface to spread.
A method of fixing a part and a part support for mounting said part via an intermediate member by using adhesive said method comprising the steps of:
- positioning the intermediate member between the part and the part support;
- and
- applying adhesive to a substantially vertical first interface and a substantially horizontal second interface between the part and the intermediate member and between the part support and said intermediate member
- the adhesive to be applied to said first interface having higher viscosity than the adhesive to be applied to said second interface.
An apparatus for fixing a part and a part support for mounting said part by using adhesive with the intermediary of an intermediate member provided between said part and said part support, said apparatus comprising:
- part support holding means for positioning and holding the part support at a preselected assembling position;
- part supporting means for supporting the part in a position adjustable relative to the part support held by said part support holding means;
- position detecting means for detecting a position of the part supported by said part supporting means;
- position adjusting means for adjusting, based on the position detected by said position detecting means, a position in which the part should be mounted to the part support held by said part support holding means;
- and
- adhesive applying means for applying the adhesive to a substantially vertical first interface and a substantially horizontal second interface between the part and the intermediate member and between the part support and said intermediate member;
- said adhesive applying means comprising first applying means and second applying means for applying the adhesive to said first interface and said second interface, respectively, the adhesive to be applied by said first applying means has higher viscosity then the adhesive to be applied by said second applying means.
A method of fixing a part and a part support for mounting said part via an intermediate member by using adhesive, said method comprising the steps of;
- positioning the intermediate member between the part end the part support:
- applying adhesive to a substantially vertical first interface and a substantially horizontal second interface between the part and the intermediate member and between the part support end said intermediate member;
- and
- half-curing, before a relative position of the part and the part support is adjusted, the adhesive applied to said first interface to a degree preventing said adhesive from dropping due to an own weight.
A method as claimed in claim 28, further comprising the step of radiating, before a relative position of the part and the part support is adjusted, light of an amount capable of half-curing the photocuring adhesive,
An apparatus for fixing a part and a part support for mounting said part by using adhesive with the intermediary of an intermediate member provided between said part and said part support, said apparatus comprising:
- part support holding means for positioning and holding the part support at a preselected assembling position;
- part supporting means for supporting the part in a position adjustable relative to the part support held by said part support holding means;
- position detecting means for detecting a position of the part supported by said part supporting means;
- position adjusting means for adjusting, based on the position detected by said position detecting means, a position in which the part should be mounted to the part support held by said part support holding means;
- and
- adhesive curing means for curing the adhesive applied to a substantially vertical first interface and a substantially horizontal second interface between the port and the intermediate member and between the part support and said intermediate member;
- and
- control means for controlling a degree of curing of the adhesive to be cured by said adhesive curing means and selecting either one of said first interface and said second interface for effecting the curing.
