Electronic Component Mounting System Dual Collation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The electronic component mounting system faces a significant productivity decline when the mounting line management apparatus and integrated management apparatus lose access to each other, preventing collation work and halting the mounting process for new supply reels, even if collation for previously mounted components is complete.
Innovation Solution
The system includes a dual collation unit setup, where the integrated management apparatus performs collation if access is available, and the mounting line management apparatus performs collation independently if access is lost, allowing continuous production by using identification information from a barcode reader to manage electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If collation work is performed by the integrated management apparatus, then centralized management and control are improved, but system reliability deteriorates when access between apparatuses is lost
Solution Approach 1:
The collation function is segmented between two independent entities: the integrated management apparatus and the mounting line management apparatus. Each can perform collation independently, allowing the system to maintain operation continuity even when one apparatus becomes inaccessible. This segmentation eliminates the single point of failure in the centralized collation system.
2Productivity
If centralized collation management is implemented, then data consistency and control are improved, but productivity deteriorates when access is unavailable
Solution Approach 1:
The mounting line management apparatus is equipped with local collation capability, allowing it to perform identification information verification independently when the integrated management apparatus is inaccessible. This local quality enhancement ensures that the mounting line can continue operations without interruption, preventing information management bottlenecks.
3Loss of time
If the system waits for access restoration before performing collation, then data accuracy is improved, but time loss increases
Solution Approach 1:
The mounting line management apparatus performs collation work in advance using locally stored identification information when the integrated management apparatus is inaccessible. This preliminary action allows the system to maintain manufacturing precision without waiting for access restoration, eliminating time delays in the collation process.

AI summary
An electronic component mounting system includes: mounting line management apparatuses disposed in each of mounting lines and an integrated management apparatus connected to the mounting line management apparatuses. The integrated management apparatus includes a first collation unit which performs collation of an electronic component based on identification information for identifying the electronic component. The mounting line management apparatus includes a second collation unit which performs collation of the electronic component. When the identification information is read out by the identification information reading-out unit, the collation of the electronic component is performed by the first collation unit if the mounting line management apparatus can access the integrated management apparatus, and the collation of the electronic component is performed by the second collation unit if the mounting line management apparatus cannot access the integrated management apparatus.
