Component Mounting System Operating State Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional component mounting devices fail to detect and inspect abnormalities on substrates beyond component drops, leading to missed quality defects and increased outflow of defective substrates.
Innovation Solution
A component mounting system with a controller and server that acquires and transmits operating state changes likely to cause quality defects, enabling inspections beyond component drops, and instructing specific substrate inspections based on these changes, reducing the risk of missed abnormalities and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If foreign matter inspection is performed only when component drop is detected, then inspection resources are saved, but substrate abnormalities other than component drops are missed
Solution Approach 1:
The system performs preliminary monitoring of operating state changes during component mounting operations. When specific operating state changes are detected, the system proactively identifies substrates that require inspection before they leave the mounting device, enabling targeted inspection scheduling and reducing the need for comprehensive inspection of all substrates.
Solution Approach 2:
The system establishes a feedback loop where operating state changes during component mounting are continuously monitored and fed back to the control unit. This feedback mechanism enables real-time identification of substrates that require inspection, allowing the system to adapt inspection requirements based on actual mounting conditions and detect potential quality issues.
2Reliability
If comprehensive substrate inspection is performed for all operating state changes, then quality defects are detected, but inspection time and productivity are reduced
Solution Approach 1:
The system applies local quality control by identifying specific substrates that require inspection based on their individual operating state changes during mounting. Instead of uniformly inspecting all substrates, the system targets only those substrates associated with specific operating state changes, thereby reducing unnecessary inspection time while maintaining high quality detection reliability.
Solution Approach 2:
The system performs partial inspection action by conducting foreign matter inspection only on substrates associated with detected operating state changes, rather than performing comprehensive inspection on all substrates. This partial action approach maintains adequate quality control while reducing overall inspection time and preserving productivity.
3Ease of operation
If no additional inspection is performed for operating state changes other than component drops, then inspection process remains simple, but substrate abnormalities are missed
Solution Approach 1:
The system enables self-service quality control by automatically monitoring its own operating state changes and autonomously identifying substrates that require inspection. The control unit processes operating state information and generates inspection requirements without external intervention, maintaining operational simplicity while improving detection reliability through automated quality monitoring.

AI summary
A component mounting system includes a component mounting device including a component mounting unit configured to mount a component on a substrate, and a controller, and a server configured to be communicable with the controller. The controller is configured or programmed to acquire a plurality of types of operating state changes that are likely to cause a quality defect, and to transmit, to the server, information according to the types of the operating state changes. The server is configured to provide information indicating an inspection type for the substrate based on the information according to the types of the operating state changes.
