Automated Component Feeding Unit Selection for Mounting Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mounting systems, operators face inefficiencies and delays due to the manual search and potential mistakes in combining component feeding units for light-emitting elements and resistance elements, leading to decreased mounting work efficiency.
Innovation Solution
A mounting system with a component mounter, storage, and an automatic unit exchange device that selects and conveys the correct combination of component feeding units based on stored combination and storage information, reducing operator effort and preventing mistakes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual combination of component feeding units is performed by operator, then flexibility in component selection is maintained, but operator workload increases and mounting efficiency decreases
Solution Approach 1:
The system performs automatic self-service by having the control section autonomously select and exchange component feeding units based on storage information and combination information, eliminating the need for operator intervention in the combination process while maintaining operational flexibility
Solution Approach 2:
The system performs preliminary actions by pre-storing component feeding units in the storage area with their characteristic ranks recorded, and pre-establishing combination information in the control section, so that when mounting is needed, the correct combinations are already prepared and can be quickly deployed without manual searching
2Reliability
If operator searches for combination target component feeding units, then correct combinations can be achieved, but time is lost and mounting start is delayed
Solution Approach 1:
The control section uses feedback from storage information (characteristic ranks of stored components) and combination information (required combinations for light-emitting elements and resistance elements) to automatically determine and select the correct component feeding units, ensuring combination accuracy without manual verification
Solution Approach 2:
The system replaces the mechanical manual searching and selection process with an automated control system that uses information processing and automatic exchange mechanisms to select and position component feeding units, dramatically reducing the time from combination decision to mounting start
3Productivity
If automatic unit exchange device is implemented, then operator load is reduced and mistakes are prevented, but system complexity increases
Solution Approach 1:
The control section serves multiple functions: it stores combination information, manages storage information for component feeding units, performs the selection logic, and controls the unit exchange device, consolidating these functions into a single multi-functional control system rather than requiring separate dedicated devices for each function
Solution Approach 2:
The storage area acts as an intermediary between the component supply source and the mounting position, buffer1 serves as an intermediary storage buffer, and the unit exchange device acts as an intermediary mechanism that bridges the storage area and mounting position, allowing the system to manage complexity through layered intermediary structures

AI summary
A mounting system including a component mounter, a storage, and a unit exchange device includes a selection section that selects a combination of the specific component feeding unit and the related component feeding unit from the component feeding unit stored in the storage based on combination information indicating a combination of the characteristic rank of the specific component and a component type of the related component corresponding to the characteristic rank, and storage information including the component type, a position, and the characteristic rank of the specific component of the component feeding unit stored in the storage; and a control section that controls the unit exchange device to take out the combination of the specific component feeding unit and the related component feeding unit from the storage and to convey the combination to the component mounter.
