Interruption Production Positioning in Electronic Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing production plans for electronic component mounting apparatuses are inefficient due to varying setup change times and optimal interruption production positions, leading to non-optimal overall production time periods.
Innovation Solution
A determination method and apparatus that search for optimal interruption production candidates within the initial production plan, calculating prior and posterior setup change times, interruption production times, and increased times to select the best position for interruption production, thereby minimizing overall production time impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If interruption production is performed for a different electronic circuit product in the initial production plan, then production flexibility is improved, but the overall production time period increases due to additional setup changes
Solution Approach 1:
The system performs preliminary calculation of setup change times for all possible interruption production positions before making the final determination. By pre-calculating the time required for setup changes at each candidate position, the system can identify the optimal position that minimizes total production time while still allowing interruption production to occur.
Solution Approach 2:
The production plan determination is made dynamic by evaluating multiple candidate positions for interruption production and selecting the optimal position based on calculated setup change times. The system adapts the production plan by choosing the best insertion point rather than using a fixed approach, thereby minimizing the impact on overall production time.
2Ease of operation
If the position of interruption production is determined empirically by a worker, then ease of operation is improved, but manufacturing precision deteriorates as the position is not necessarily optimal
Solution Approach 1:
The patent replaces the manual empirical determination method with an automated computer-based calculation system. The determination apparatus automatically calculates setup change times and identifies the optimal interruption production position, substituting human judgment with computational analysis to achieve both ease of operation and optimal results.
Solution Approach 2:
The system uses feedback from calculated setup change times to determine the optimal interruption production position. By computing and comparing the time requirements for different positions, the system receives feedback on which position minimizes production time impact, thereby objectively determining the best position rather than relying on empirical methods.

AI summary
An object is to provide a determination method and a determination apparatus for a production plan which can shorten time for a setup change by interposing an interruption production in an optimal position with respect to the production plan in which production is performed using an electronic component mounting apparatus. The determination method for a production plan includes an interposing-available candidate search process in which an interposing-available candidate in which the interruption production can be interposed within an initial production plan is searched for, a time calculation process for a prior/posterior setup change, in which time for the prior/posterior setup change which is required for the setup change before and after the interruption production is calculated for each searched for interposing-available candidate, and a production plan determination process in which the interruption production is interposed in the interposing-available candidate selected in the initial production plan so as to determine the production plan.
