Board Machine Trace Log Classification for Faster Error Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trace assistance devices for board work machines struggle to efficiently identify the cause of mounting errors from large volumes of accumulated trace logs, leading to decreased production efficiency.
Innovation Solution
A trace assistance device that classifies and stores trace logs by operation environment or control, allowing for the acquisition of related logs belonging to the same or similar categories as a reference log when a trigger event occurs, facilitating analysis and error identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trace logs are accumulated to improve traceability, then the ability to trace past operations is improved, but the difficulty of acquiring relevant logs for error analysis increases
Solution Approach 1:
The patent segments the large volume of trace logs by adding classification tags that categorize logs according to the operation environment (e.g., mounting head type, board type, component type) and operation control (e.g., suction pressure, mounting speed). This segmentation enables efficient retrieval of relevant logs by filtering based on tag combinations, resolving the contradiction between maintaining comprehensive traceability and enabling easy log acquisition for error analysis.
2Reliability
If multiple trace logs are stored to improve traceability, then the completeness of operation history is improved, but the time required to identify error causes increases
Solution Approach 1:
The patent applies preliminary action by pre-classifying and tagging trace logs during the logging process itself, rather than performing classification when error analysis is needed. The classification tags are added in advance based on the operation environment and control parameters, so that when an error occurs, relevant logs can be immediately retrieved by matching tags without time-consuming post-processing classification.
3Ease of operation
If trace logs are classified by adding tags, then the ease of acquiring relevant logs is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal tagging system where a single tag structure serves multiple classification purposes. The same tags that classify operation environment (mounting head, board, component) also classify operation control parameters (pressure, speed, temperature). This multi-functional tagging approach enables easy log acquisition through flexible tag combination filtering without requiring separate complex classification systems for different log types.

AI summary
A trace assistance device of a board work machine, including: a storage section configured to classify multiple trace logs in which an operation history of the board work machine performing a predetermined work on a board is recorded into a category relating to an operation environment or an operation control and store the multiple trace logs; and a log acquisition section configured to define the trace log, in which a series of operations relating to the trigger event is recorded, as a reference log in a case where a predetermined trigger event occurs in a work by the board work machine, and acquire, from the multiple trace logs stored in the storage section, a related log belonging to a same category or a similar category with the reference log.
