Multi-Feeder Exchange Mechanism for Faster Mounting Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exchange devices for component mounting systems require significant non-production time for exchanging cassette-type feeders or component supply units, leading to inefficiencies in board production, as each element is exchanged individually, causing interruptions and prolonging setup changes.
Innovation Solution
An exchange device with multiple holding sections that can move independently in the attachment/detachment direction, allowing for simultaneous handling and exchange of multiple exchangeable elements, such as tape feeders, reducing the time required for component mounting device downtime and improving production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If exchangeable elements are exchanged one by one using conventional exchange devices, then the exchange operation is simple to perform, but the non-production time is prolonged and production efficiency is reduced
Solution Approach 1:
The exchange device is divided into multiple independent holding sections (first holding section, second holding section, etc.), each capable of independently holding and exchanging exchangeable elements. This segmentation allows parallel exchange operations to occur simultaneously across different holding sections, thereby reducing total exchange time and improving production efficiency without requiring a completely new monolithic device design.
Solution Approach 2:
Multiple holding sections are integrated into a single exchange device structure that shares common components such as the moving section, driving devices, and control system. This merging approach enables simultaneous exchange of multiple exchangeable elements while avoiding the need for completely separate exchange devices, thus improving productivity without proportionally increasing device complexity.
2Loss of time
If multiple exchangeable elements are exchanged simultaneously, then non-production time is shortened, but the device complexity increases
Solution Approach 1:
The exchange device incorporates a moving section that can dynamically reposition holding sections along the arrangement direction, and attachment/detachment directional moving sections that can independently move holding sections in the attachment/detachment direction. This dynamic positioning capability allows the device to efficiently handle multiple exchangeable elements simultaneously while maintaining a relatively compact and manageable structure through coordinated motion rather than static complexity.
Solution Approach 2:
The exchange device is designed with multiple holding sections that can universally handle different types of exchangeable elements (such as tape feeders or component supply units). Each holding section can perform the same exchange function independently, allowing the device to simultaneously exchange multiple elements of the same or different types, thereby reducing non-production time without requiring specialized structures for each element type.
3Duration of action of moving object
If a single holding section is used for exchange operations, then the device structure is simple, but the exchange operation time is prolonged
Solution Approach 1:
The exchange device is divided into multiple independent holding sections (first holding section, second holding section, etc.), each capable of independently holding and exchanging exchangeable elements. This segmentation allows parallel exchange operations to occur simultaneously across different holding sections, thereby reducing total exchange time and improving production efficiency without requiring a completely new monolithic device design.
Solution Approach 2:
The exchange device is configured with multiple holding sections, which may be more than the minimum single holding section needed for basic exchange operations. This excessive action approach allows the device to handle multiple exchangeable elements simultaneously, reducing exchange operation time and improving productivity, while the modular nature of the holding sections keeps the overall device structure manageable.

AI summary
An exchange device to exchange an exchangeable element includes an arrangement directional moving section to move with respect to the component mounting device in the arrangement direction; multiple attachment/detachment directional moving sections provided in the arrangement directional moving section to move independently of each other in the attachment/detachment direction of the exchangeable element; at least one holding section provided in each of the multiple attachment/detachment directional moving sections to hold the exchangeable element; an arrangement direction driving device to move the arrangement directional moving section in the arrangement direction; and an attachment/detachment direction driving device to move multiple attachment/detachment directional moving sections, independently of each other, in the attachment/detachment direction.
