Equipment Unit Allocation for Electronic Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic component mounting systems face challenges in accurately managing equipment units, leading to incorrect allocation and potential production stoppages when handling multiple production lots with shared equipment units.
Innovation Solution
An electronic component mounting system with a production plan data storage unit, mounting data storage unit, component library data storage unit, inventory data storage unit, necessary unit data creation unit, and unit reservation unit to manage and allocate equipment units based on production plan data and mounting data, ensuring correct allocation and availability for each production lot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If equipment units are shared among multiple production lots to improve resource utilization, then productivity increases, but equipment unit allocation accuracy deteriorates leading to production stoppages
Solution Approach 1:
The system performs preliminary allocation of equipment units to production lots before actual production begins. The allocation result storage unit records which equipment units are assigned to which production lots in advance, ensuring that when production starts, the correct equipment units are already reserved and available, preventing both over-allocation and under-allocation scenarios.
Solution Approach 2:
The system implements feedback mechanisms where the production lot management unit continuously monitors equipment unit allocation status and provides feedback to adjust allocations. When equipment units are actually used or become unavailable, the system receives feedback and reallocates resources accordingly, ensuring accurate tracking and prevention of production stoppages.
2Manufacturing precision
If setup instructions are prepared for each substrate type to improve manufacturing precision, then mounting accuracy improves, but device complexity increases making it difficult to manage multiple production lots
Solution Approach 1:
The production lot management unit serves multiple functions: it manages equipment unit allocations, tracks production status, coordinates setup instructions, and monitors resource availability. By creating a universal management system that handles all these tasks centrally, the patent reduces the need for separate management mechanisms for each substrate type while maintaining mounting accuracy through proper equipment-unit-to-production-lot matching.
Data Source
AI summary
Necessary unit data indicative of the type and number of equipment units used in component mounting operation is obtained on the basis of production plan data, mounting data, and component library for each of production lots in advance. New allocation processing for allocating an equipment unit necessary for production execution of a new production lot to be newly produced on an electronic component mounting line for the new production lot on the basis of the necessary unit data is executed, and component reservation processing for registering the allocation result as the inventory data is conducted by a unit reservation unit.
