Electronic Component Mounting System Deviation Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mounting systems, frequent changes in the assignment of electronic components between mounting apparatuses lead to inaccurate feedback of inspection results, causing positional deviations in electronic components that are not corrected in a timely or accurate manner.
Innovation Solution
A mounting system with a storage and controller that stores formats for each substrate including divisional information of mounting apparatuses and deviation amounts of electronic components, allowing real-time updates and corrections based on changes in assignment, ensuring accurate feedback and correction of positional deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the assignment of mounting of electronic components by mounting apparatus is changed frequently to raise mounting tact, then mounting productivity is improved, but inspection result feedback accuracy deteriorates
Solution Approach 1:
The patent segments the substrate production process into distinct formats, where each format contains divisional information linking specific electronic components to specific mounting apparatuses. This segmentation allows the system to track and maintain accurate inspection result feedback even when assignments change frequently, as each format acts as an independent record that can be updated without affecting others.
Solution Approach 2:
The patent implements a dynamic format management system where the divisional information in each format can be changed in response to assignment changes. When a mounting apparatus assignment changes, the corresponding format is updated to reflect the new assignment, ensuring that inspection results are always feedback to the correct apparatus despite frequent reconfigurations.
2Productivity
If multiple mounting apparatuses are connected in line to raise mounting efficiency, then productivity is improved, but tracking and correcting positional deviation becomes more complex
Solution Approach 1:
The patent introduces formats as an intermediary data structure that mediates between multiple mounting apparatuses and the inspection apparatus. Each format contains divisional information that acts as a mapping table, simplifying the tracking of which apparatus mounted which component. This intermediary layer reduces the complexity of managing assignments across multiple apparatuses by providing a centralized information repository.
3Reliability
If real-time updates of divisional information are implemented when assignment changes, then inspection feedback accuracy is improved, but system complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-defining the format structure with divisional information fields before assignment changes occur. The system is designed to accommodate future assignment changes through this pre-established framework, allowing real-time updates without requiring complex reconfiguration. The format template is prepared in advance, reducing the complexity of real-time modifications.

AI summary
A mounting system including: a storage that stores plural formats for each substrate including divisional information of a mounting apparatus indicating which of plural mounting apparatuses that divisionally mount plural electronic components on a substrate mounts what electronic component on the substrate and information on a deviation amount of an electronic component indicating how much each of the electronic components mounted on the substrate and inspected by an inspection apparatus is deviated from its regular position; and a controller that changes, according to a change of an assignment of mounting, the divisional information in a format corresponding to the substrate for which the assignment has been changed, and controls the mounting apparatus that has mounted the electronic component and has been specified from the mounting apparatuses to mount the electronic component on the substrate after correcting a deviation amount based on the information on a deviation amount.
