Component Mounting Device Substrate Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounting devices with multiple lanes, product-type switching operations often require stopping the operation of one lane, leading to potential misinterpretation of ongoing manufacturing, especially when abnormalities occur, causing unnecessary reloading of the mounting program.
Innovation Solution
A component mounting device with substrate presence/absence detecting sections and an input control processing system that prohibits product-type switching operations if substrates are present, allowing for seamless lane operation changes without interrupting continuous manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If product-type switching operation is performed for a mounting lane that continues manufacturing, then the mounting program is reloaded, but this causes unnecessary operation interruption and potential errors
Solution Approach 1:
The control unit performs preliminary detection of substrate presence before allowing product-type switching operations. By checking whether a substrate is present in the mounting lane in advance, the system prevents switching operations from being executed during continuous manufacturing, thereby avoiding unnecessary program reloading and ensuring operational reliability.
2Adaptability or versatility
If the operator stops a mounting lane for abnormality handling or data input, then the lane operation is interrupted, but this may be mistaken for end of manufacturing
Solution Approach 1:
The control unit provides visual feedback through distinct display indicators showing the actual operation status of each mounting lane. When a lane is stopped for abnormality handling or data input, the display clearly indicates this state rather than showing it as end of manufacturing. This feedback mechanism prevents misinterpretation of operation status while maintaining operational flexibility.
3Ease of operation
If product-type switching is allowed for all mounting lanes, then operation flexibility is improved, but continuous manufacturing may be accidentally interrupted
Solution Approach 1:
The control unit performs preliminary detection of substrate presence in each mounting lane before enabling product-type switching operations. By checking substrate presence in advance, the system allows switching only when appropriate (when no substrate is present), preventing accidental interruption of continuous manufacturing while maintaining operational flexibility when needed.

AI summary
In the operation execution step wherein the operation switches are clicked to execute the operation related to product-type switching, if the substrate presence/absence detecting sensors S1, S2 that detect the presence/absence of substrates in the front-side substrate transporting mechanism 11A and rear-side substrate transporting mechanism 11B detect the presence of substrates, it is judged that the manufacturing operation of the corresponding substrate type has not ended, and the input control processing is executed so that the input operation by the operation switch for executing the operation related to product-type switching is prohibited. As a result, it is possible to prevent the problems related to reloading of the mounting program before the manufacturing has ended.
