Preparation Device for Component Feeder Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting devices face productivity losses due to the need to acquire images of components during the mounting process, which reduces efficiency and increases cycle time.
Innovation Solution
A preparation device that captures images of a holding member attached to a component supply device, executes an initial setting process, and stores correspondence information associating the images with identification information of the component supply device, allowing for determination of component presence without capturing images during the mounting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If images are acquired during the mounting process to determine component presence, then component detection accuracy is improved, but productivity decreases due to increased cycle time
Solution Approach 1:
The patent applies preliminary action by capturing images of the holding member in advance during a preparation phase before the actual mounting process begins. The preparation capturing section acquires images of the holding member at a preparation position, and the preparation control section stores these images along with identification information of the component supply device. This allows the mounting device to reference pre-captured images during mounting, eliminating the need to capture images during the mounting process itself, thus maintaining detection accuracy while improving productivity.
2Measurement precision
If images are captured at the start of mounting process for each feeder, then component presence can be determined, but productivity is reduced due to the large number of feeders requiring preparation
Solution Approach 1:
The patent applies segmentation by dividing the system into distinct functional sections: a preparation device with a preparation capturing section for capturing images of the holding member, and a mounting device with a mounting capturing section for capturing images during the mounting process. The preparation control section manages image capture and storage for multiple feeders in advance, while the mounting control section uses these pre-stored images during mounting operations. This segmentation allows independent optimization of preparation and mounting processes, enabling efficient handling of multiple feeders without compromising throughput.
3Productivity
If the preparation device captures images of the holding member and stores correspondence information, then the mounting device can determine component presence without capturing images during mounting, but device complexity increases
Solution Approach 1:
The patent applies the intermediary principle by introducing a preparation control section that acts as a mediator between the preparation capturing section and the mounting control section. The preparation control section captures images of the holding member, extracts feature values, stores correspondence information linking images to component supply device identification, and provides this information to the mounting control section. This intermediary structure centralizes the complex tasks of image capture, feature extraction, and data management in the preparation phase, simplifying the mounting process while maintaining high productivity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables the preparation device to suppress decreases in mounting process efficiency without reducing cycle time, by obtaining necessary images and feature values during the preparation stage rather than during the mounting process.

AI summary
A preparation device includes a fixing section configured to fix a component supply device to which a holding member configured to hold a component is attached and feed the holding member, a preparation capturing section configured to capture an image of the holding member fixed to the fixing section, and a preparation control section configured to execute an initial setting process of the holding member by using a captured image captured by the preparation capturing section and cause a storage section to store correspondence information that associates a captured image including a region of the holding member captured by the preparation capturing section in which the component is present and/or a feature value with identification information of the component supply device, and/or correspondence information that associates a captured image including a region of the holding member captured by the preparation capturing section in which the component is not present and/or a feature value with the identification information of the component supply device.
