Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounting lines with multiple machines, communication failures between configuration management devices and component mounting machines lead to unnecessary production suspensions, degrading efficiency as the system cannot confirm whether installed devices are allowed for use.
Innovation Solution
A component mounting line management device with a configuration management device that stores installation device identification and location information, allowing local determination of device usage through both communication-normal-time and communication-abnormal-time sections, ensuring continuous production even without communication with the central management device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication between configuration management device and component mounting machine is required for installation device determination, then production quality control is improved, but production efficiency deteriorates during communication failures
Solution Approach 1:
The system divides the installation device determination function into two independent parts: a central configuration management device for quality control and local component mounting machines for continuous operation. Each machine has its own determination section that can operate independently when communication is unavailable, allowing production to continue while maintaining quality control through the central device when communication is available.
Solution Approach 2:
The configuration management device performs preliminary determination of installation device compatibility before production starts. The determination results are stored in advance, allowing component mounting machines to make quick local decisions without real-time communication, thus preventing production delays while ensuring quality control through pre-validated configurations.
2Reliability
If centralized management of installation device information is implemented, then device compatibility is improved, but system complexity increases during communication failures
Solution Approach 1:
The system segments the management function by distributing determination capabilities to individual component mounting machines while maintaining centralized information storage. Each machine has its own determination section that uses locally stored configuration data, reducing the complexity burden during communication failures while maintaining compatibility through centralized management when communication is available.
Solution Approach 2:
The system creates local copies of installation device information and determination results within each component mounting machine. These copies enable machines to operate independently during communication failures without losing compatibility control, as the local copies contain the necessary configuration data and determination outcomes from the centralized system.
3Manufacturing precision
If communication is required for installation device verification, then manufacturing precision is improved, but production continuity deteriorates
Solution Approach 1:
The verification function is segmented between centralized configuration management and local execution. The configuration management device provides precise verification of installation device compatibility, while local component mounting machines maintain production continuity by using stored determination results when communication is unavailable, thus balancing precision with continuity.
Solution Approach 2:
Installation device verification is performed in advance by the configuration management device before production begins. The verification results are stored locally at component mounting machines, allowing production to continue without interruption even when communication with the central device fails, thus maintaining both manufacturing precision and production continuity.

AI summary
There is provided a component mounting line management device that can determine whether an installation device detachably attached to a component mounting machine is used, when communication between a configuration management device and the component mounting machine is impossible. In the component mounting line management device (1) according to the present invention, each component mounting machine or each installation device includes an installation device information memory device (11). The installation device information memory device (11) stores installation device identification information of the installation device attached at an installation position, and location information on the installation position in correlation with each other. Each component mounting machine includes a communication-abnormal-time installation device determination section (12). When communication with the configuration management device (1H) is impossible, the communication-abnormal-time installation device determination section (12) compares installation device identification information of the installation device mounted at the installation position and the location information on the installation position, to installation device identification information of the installation device and location information correlated with the installation device identification information, which are stored in the installation device information memory device (11), so as to determine whether the installation device is used.
