Board Production Image Tracing for Suspect Processing Results
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tracing devices fail to accurately record traceability information when image processing results are erroneously determined normal, making it difficult to identify the cause of abnormalities in production processes.
Innovation Solution
A tracing device that records image data as traceability information only when the image processing results do not meet certain reliability criteria, allowing for the identification of abnormal image processing steps by determining appropriateness conditions and recording image data and parameters associated with the processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all image data is recorded irrespective of image processing results, then complete traceability is achieved, but data management complexity and storage requirements increase significantly
Solution Approach 1:
The patent applies local quality by differentiating the recording treatment based on image processing results. Only image data with specific characteristics (abnormal processing results) are recorded, rather than uniformly recording all image data. This selective approach reduces data volume while maintaining traceability for critical cases, thereby lowering data management complexity without completely sacrificing traceability capability.
2Device complexity
If only abnormal image data is recorded, then data storage is reduced, but traceability of erroneously determined normal cases is lost
Solution Approach 1:
The patent implements preliminary action by evaluating image processing results before determining whether to record image data. The system预先 (in advance) assesses whether the image processing result is abnormal or suspicious, and based on this preliminary evaluation, decides to record the image data. This prevents loss of traceability for potentially problematic cases while avoiding unnecessary recording of clearly normal cases.
Solution Approach 2:
The patent introduces an intermediary mechanism - the image processing result evaluation - that mediates between the extremes of recording all image data versus recording only abnormal cases. By using the processing result as an intermediary criterion, the system selectively records data with suspected abnormalities, achieving a balance between traceability and storage efficiency.
3Reliability
If image processing reliability is low, then false normal determinations occur, but these cases cannot be traced without additional recording mechanisms
Solution Approach 1:
The patent implements feedback by using image processing results to control the recording action. When the image processing result indicates low reliability or abnormality, the system feeds back this information and triggers recording of the corresponding image data. This feedback mechanism ensures that cases with potential false normal determinations are captured and preserved for later traceability and analysis.

AI summary
A tracing device includes an appropriateness determination section configured to determine whether an image processing, which is executed in a production process of a board product by a board work machine, satisfies an appropriateness condition indicating reliability of a result of the image processing when the result of the image processing stays within a permissible range in which the result of the image processing is determined normal and an information management section configured to record image data used in the image processing as traceability information according to the result of the determination made by the appropriateness condition determination section.
