Optimization Program for Multi-Board Substrate Mounting Work
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mounting work systems face inefficiencies in throughput when dealing with multiple-board substrates that have defective circuit patterns, as the presence of defective patterns leads to standby times for mounting machines, reducing overall system productivity.
Innovation Solution
An optimization program that distributes the mounting work procedures across multiple mounting machines, ensuring all machines work on all circuit patterns, and adjusts procedures based on each machine's mounting performance to equalize workload and minimize waiting times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mounting work is divided between multiple mounting work machines, then mounting work can be performed in parallel improving throughput, but when defective circuit patterns are present, some machines must wait reducing overall throughput
Solution Approach 1:
The patent dynamically adjusts the mounting work procedure distribution based on the presence of defective circuit patterns. When defects are detected, the system reconfigures which machines perform mounting work on which circuit patterns, allowing machines that would otherwise be idle to utilize their capacity on valid patterns, thereby eliminating standby time while maintaining parallel operation
Solution Approach 2:
The system changes the assignment parameters of mounting work procedures based on defect information. By detecting defective circuit patterns and modifying the work distribution parameters accordingly, the system ensures that all mounting work machines have productive tasks whenever possible, converting potential idle time into productive mounting operations
2Adaptability or versatility
If mounting work procedures are set to handle multiple-board substrates with potential defects, then flexibility is improved, but complexity of work procedure settings increases
Solution Approach 1:
The system incorporates feedback from defect detection to automatically adjust mounting work procedures. By using defect information as feedback, the system dynamically optimizes work distribution without requiring complex manual programming, reducing setting complexity while maintaining high adaptability to different substrate configurations and defect patterns

AI summary
With multiple-board substrate defined as a circuit substrate provided with multiple boards of circuit pattern on which multiple electronic components are mounted, when performing mounting work of multiple electronic components on a multiple-board substrate using three mounters lined up in a row, electronic component mounting work procedures are set such that mounting work of electronic components for each of multiple circuit patterns is performed by all three mounters. Work procedures for mounting work of electronic components surrounded by the dashed lines are set to a first mounter, work procedures for mounting work of electronic components surrounded by the single-dashed solid lines are set to a second mounter, and work procedures for mounting work of electronic components surrounded by the double-dashed solid lines are set to a third mounter.
