Soldering Work Traceability Using Time-Synced Full-Board Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work management systems for soldering operations lack effective traceability of soldering works performed on a board, as they primarily capture images and data from specific joining locations rather than the entire board, making it difficult to ensure position traceability and monitor the soldering process comprehensively.
Innovation Solution
A work management apparatus and method that includes capturing and storing chronologically continuous images of the entire board and monitor information associated with identification information, allowing for chronological display of captured images and monitor data, ensuring accurate traceability and monitoring of soldering works.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If images are captured only from specific joining locations, then the focus on critical areas is improved, but the traceability of the entire board deteriorates
Solution Approach 1:
The patent divides the board into multiple regions of interest (joining locations) and captures images from each region separately. This segmentation allows focused detection at critical joining points while the system maintains traceability by associating each captured image with its specific board position and identification information.
Solution Approach 2:
The patent adds the dimension of spatial coordinates and identification information to the captured images. By embedding position data, board ID, and location information within the image metadata, the system achieves comprehensive traceability without sacrificing the focused detection capability at specific joining locations.
2Loss of information
If comprehensive images of the entire board are captured, then the traceability is improved, but the data storage and processing complexity increases
Solution Approach 1:
The patent extracts only the essential traceability information (board ID, position coordinates, location description) from the complete board context and stores it as metadata associated with each captured image. This extraction approach maintains comprehensive traceability while significantly reducing the data storage and processing requirements compared to capturing and managing entire board images.
3Reliability
If multiple parameters are monitored simultaneously, then the monitoring comprehensiveness is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent merges multiple monitoring parameters (temperature, humidity, image data, position information) into a single integrated data structure associated with each board ID and location. This consolidation allows comprehensive monitoring while simplifying operation, as users can access all parameters through a unified interface rather than managing separate monitoring systems.

AI summary
A work management apparatus, a work management method, and a non-transitory computer-readable storage medium storing a control program for managing a plurality of soldering works to be manually performed on a board, include: storing, in association with identification information of the board acquired by an identification information acquisition device connected to the work management apparatus, captured images of an entirety of the board and monitor information being chronologically continuous and respectively acquired by an image-capturing device and a soldering monitor device each connected to the work management apparatus in the soldering works; and chronologically displaying each of the captured images and monitor information stored in association with one piece of identification information selected from among the stored identification information of the board in a state where a capturing date and time of the captured image and an acquisition date and time of the monitor information match.
