Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for measuring mounting accuracy in component mounting machines are labor-intensive and inefficient, requiring operators to repeatedly open and close machine covers to set and remove mounting accuracy measurement boards, making the process cumbersome and time-consuming.
Innovation Solution
A system that allows component mounting machines to switch between production and mounting accuracy measurement modes, enabling a single mounting accuracy measurement board to be conveyed automatically between machines along the board conveyance path for sequential measurement, reducing operator workload and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the operator manually sets the mounting accuracy measurement board in each component mounting machine, then the mounting accuracy can be measured, but the operator workload increases significantly and the measurement process becomes time-consuming
Solution Approach 1:
The system enables self-service measurement by allowing the mounting accuracy measurement board to be automatically conveyed through multiple component mounting machines. The board itself serves as the measurement medium that travels through the system, eliminating the need for operators to manually set up measurement boards in each machine. The measurement process becomes autonomous, with the board being sequentially processed through machines 14-1 to 14-n without human intervention.
Solution Approach 2:
A single mounting accuracy measurement board is designed to be universally compatible with multiple component mounting machines (14-1 to 14-n). The board serves multiple functions: it acts as a measurement target for different machines, a conveyance medium through the production line, and a reusable measurement medium that can be processed sequentially by multiple machines. This multi-functionality eliminates the need for separate measurement boards for each machine.
2Measurement precision
If the operator repeatedly opens and closes machine covers to set measurement boards, then mounting accuracy measurement is possible, but the measurement process becomes extremely troublesome and inefficient
Solution Approach 1:
The manual mechanical operation of opening covers, setting boards, and closing covers is replaced by an automated conveyance system. The board conveyance mechanism automatically transports the measurement board through the component mounting machines, substituting the repetitive mechanical actions of the operator with an automated mechanical system that integrates with the existing production line conveyance infrastructure.
Solution Approach 2:
The measurement process achieves continuity by seamlessly integrating the measurement board conveyance into the existing board conveyance path. The board moves continuously through the system from one machine to the next without interruption, maintaining the flow of useful action. The measurement operations occur during the natural conveyance process, eliminating idle time and repetitive setup actions.
3Measurement precision
If multiple component mounting machines measure mounting accuracy individually with separate measurement boards, then each machine's accuracy can be assessed, but the process requires multiple boards and increased operator intervention
Solution Approach 1:
The patent merges the measurement processes of multiple component mounting machines into a single integrated workflow. Instead of separate measurement operations with individual boards, the system combines all measurement activities into one continuous process using a single measurement board that sequentially visits each machine. This consolidation reduces the number of measurement boards needed and simplifies the overall measurement system architecture.

AI summary
Each of multiple component mounting machines constituting a component mounting line is configured to switch between a production mode in which a component is mounted on a circuit board that has been conveyed in and then conveyed out, a mounting accuracy measurement mode in which a mounting accuracy measurement component is mounted at a predetermined position on a mounting accuracy measurement board and the mounting accuracy is measured, and a pass mode in which a component is conveyed out without being mounted on the board conveyed in. When the control mode of two or more component mounters among the multiple component mounting machines is the mounting accuracy measurement mode, the mounting accuracy is measured by conveying the mounting accuracy measurement board along the board conveyance path, and the two or more component mounting machines sequentially use the mounting accuracy measurement board to measure the mounting accuracy.
