Component Mounting System Defect Investigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounting systems, identifying the cause of abnormalities detected during the mounting process is challenging due to the need for operators to manually analyze extensive image data captured by cameras, leading to increased man-hours and inefficiency.
Innovation Solution
A component mounting system that includes a camera to image the mounting process, store video data in memory, and extract specific image data based on abnormality information from an inspector, allowing for efficient output of relevant image data to facilitate quicker investigation of defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an operator checks all image data captured during mounting process to investigate abnormality cause, then complete information is obtained, but many man-hours are required
Solution Approach 1:
The system extracts only the image data corresponding to defective boards from the entire mounting process video stream. When the inspector detects an abnormality, the identification information (board ID, position, timing) is used to extract only the relevant image segments, eliminating the need for operators to review all image data and significantly reducing analysis time while preserving complete information about the defect.
2Reliability
If monitoring camera images all operations during mounting process, then complete visual record is obtained, but data analysis burden increases
Solution Approach 1:
The system performs preliminary organization of image data during the mounting process by associating each image segment with identification information (board ID, position, timing). This preliminary tagging and organization eliminates the need for complex post-process analysis, as the data is already structured and linked to specific boards and operations, reducing analysis complexity while maintaining complete visual records.

AI summary
A component mounting system includes a mounting machine configured to perform a mounting process of a component on a board by an operation of a unit for the mounting process, an inspector configured to perform an inspection process by using an image of the board after the mounting process and output abnormality information capable of specifying a defective board having an abnormality detected in the inspection process, a camera configured to image the operation of the unit in the mounting machine during the mounting process in a video to store image data in a memory, and a data output section configured to extract image data during the mounting process of the defective board from the memory based on the abnormality information and output the image data to an outside.
