Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component crimping apparatuses using photo-curable adhesive members, light irradiation can prematurely photocure adhesive members not targeted for crimping, leading to crimping failures when the number of components exceeds the number of crimping tools.
Innovation Solution
A component crimping apparatus with a substrate holding part, supporting parts featuring transparent members and a light shielding member to block light from reaching non-targeted adhesive members, ensuring precise light application only to targeted electrodes during crimping operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If light irradiation is applied to photocure adhesive members during crimping operations, then bonding strength is improved, but premature photocuring of non-targeted adhesive members occurs causing crimping failure
Solution Approach 1:
The patent applies local quality by making the supporting part transparent only in the specific region where light irradiation is needed for adhesive curing, while other regions remain opaque or are shielded. This allows light to selectively reach only the targeted adhesive member beneath the electrode being crimped, preventing premature curing of other adhesive members while ensuring adequate curing of the targeted one, thus resolving the contradiction between bonding strength and crimping success rate
2Productivity
If the number of components to be crimped exceeds the number of crimping tools, then productivity is reduced requiring multiple operations, but selective light irradiation becomes necessary to prevent premature curing
Solution Approach 1:
The patent segments the supporting part into multiple regions with different light transmission properties. Each region corresponds to a specific electrode position, allowing independent control of light irradiation to each region. This segmentation enables selective photocuring of adhesive members at different positions during sequential crimping operations, preventing premature curing while maintaining productivity even when component count exceeds tool count
3Manufacturing precision
If transparent members are installed only at specific electrode positions, then precise light control is achieved, but the structure becomes more complex
Solution Approach 1:
The patent makes the supporting part serve multiple functions: it provides mechanical support for electrodes, enables selective light transmission through transparent regions, and acts as a light shielding structure in non-transparent regions. By integrating these functions into a single supporting part rather than adding separate components, the patent achieves precise light irradiation control while minimizing structural complexity

Function Achieved in This Case
Prevents premature photocuring of adhesive members, thereby preventing crimping failures and ensuring successful bonding of components to the substrate even when the number of components exceeds the number of crimping tools.
Implementation Method 1

AI summary
A component crimping apparatus includes: a substrate holding part that holds a substrate of a transparent material, a component previously attached to each electrode of electrodes juxtaposed in an edge of the substrate through a photo-curable adhesive member; a supporting part having a base part with an optical path and a transparent member on the base part and connected to the optical path, and supports, by the transparent member, a region under a targeted electrode in the substrate; a crimping tool arranged over the transparent member and presses the component to the substrate; a light irradiating part that irradiates the adhesive member attached to the targeted electrode with light through the optical path; and a light shielding member that covers a portion in which the transparent member is not installed in an opening part of the optical path in the base part.
