Optical Component Support Structure for UV Adhesive Curing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In optical devices where a silicon lens is used, the ultraviolet light-blocking properties of silicon hinder effective curing of ultraviolet curable adhesives, making bonding difficult.
Innovation Solution
Incorporating a support part with a first support portion that allows light to pass through and a metallized layer to reflect light onto the adhesive, ensuring adequate curing of both the first and second adhesive layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a silicon lens is used as an optical component, then optical performance is improved, but ultraviolet light transmission is blocked preventing adhesive curing
Solution Approach 1:
The optical component is divided into a light-transmitting portion (optical element part) and a support portion. The support portion includes an optical opening that segments the structure to allow UV light to reach the adhesive layer without compromising the optical performance of the lens portion.
Solution Approach 2:
A mirror is introduced as an intermediary element to reflect ultraviolet light onto the adhesive layer. This mediator enables the UV light to bypass the silicon lens and effectively cure the adhesive from a different angle.
2Strength
If the support part is made opaque to block light, then structural integrity is improved, but adhesive curing is prevented
Solution Approach 1:
The support part is segmented by introducing an optical opening that allows UV light transmission. This segmentation enables the support structure to maintain its mechanical strength while creating a light path for adhesive curing.
Solution Approach 2:
The support part has different optical properties in different regions: most of the support structure remains opaque for structural integrity, while the optical opening region is designed to be transparent to UV light to enable adhesive curing.
3Strength
If ultraviolet curable adhesive is used for bonding, then bonding strength is improved, but curing is prevented by silicon lens blocking
Solution Approach 1:
A mirror is positioned to reflect ultraviolet light onto the adhesive layer, serving as a mediator that redirects the curing light around the silicon lens to achieve effective adhesive bonding.
Solution Approach 2:
The curing light is introduced from a different spatial dimension by using the mirror to reflect light onto the adhesive layer from the side, rather than attempting to pass light through the silicon lens from the front.
