Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for mounting light-emitting components on illumination boards face challenges due to variations in positional deviations between actual and reference positions, leading to reduced productivity and quality.
Innovation Solution
Classifying light-emitting components into ranks based on positional deviations and using corresponding correction values to group and mount them, allowing for accurate positioning without extensive recognition processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If optical recognition processing is performed on each component during mounting to correct positional deviations, then mounting precision is improved, but productivity deteriorates due to the time required for recognition processing
Solution Approach 1:
The patent applies preliminary action by performing optical recognition and rank classification of light-emitting components before the actual mounting process. Components are recognized, classified into ranks based on positional deviations, and grouped in advance, so that during mounting only simple rank identification is needed rather than full optical recognition of each component's position. This preliminary classification resolves the contradiction by preparing data beforehand to enable fast mounting while maintaining precision.
2Ease of manufacture
If components are supplied in mixture irrespective of positional deviations, then ease of supply is improved, but mounting quality deteriorates due to inability to reflect variations in positional deviations
Solution Approach 1:
The patent applies local quality by differentiating component supply based on their specific positional deviation characteristics. Instead of uniform treatment, components are classified into multiple ranks according to their local positional deviation properties and supplied separately. This allows the mounting process to apply appropriate correction strategies for each rank, improving mounting quality while maintaining ease of supply through systematic categorization.
Solution Approach 2:
The patent segments the component supply process by dividing light-emitting components into multiple ranks based on their positional deviations. Rather than supplying all components together as a homogeneous group, they are segmented into rank 1, rank 2, etc., based on recognition results. This segmentation enables targeted mounting strategies for each group, resolving the contradiction between ease of supply and mounting quality.
3Manufacturing precision
If position correction processing is performed on each component during mounting based on recognition results, then mounting precision is improved, but productivity deteriorates due to time consumption in recognition and correction processing
Solution Approach 1:
The patent performs preliminary recognition and rank classification of all light-emitting components before mounting. The positional deviations are measured and components are assigned to ranks in advance. During mounting, only the rank information needs to be referenced for position correction, rather than performing full optical recognition and calculation for each component. This preliminary action significantly reduces mounting time while maintaining precision.
Solution Approach 2:
The patent creates a rank classification model that represents the positional deviation characteristics of components. Instead of processing each component's full positional data during mounting, a simplified rank copy is used that captures the essential deviation information. This copying approach maintains mounting precision while dramatically reducing the computational and time overhead during the actual mounting process.
