Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component supply systems face challenges in accurately determining whether scattered components can be held due to orientation and distance issues, leading to inefficiencies in component pickup.
Innovation Solution
A component supply system that includes a holding tool, an imaging device, and a control device with a first calculating section to determine if the calculated index value of the component's side surface matches a set value, allowing the control section to control the holding tool's movement for successful component pickup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional methods are used to determine whether scattered components can be held, then the determination process is simple, but the accuracy of determining holdability is insufficient
Solution Approach 1:
The patent replaces conventional mechanical judgment methods with an optical imaging system. An imaging device captures images of scattered components, and image processing algorithms automatically determine holdability by analyzing component orientation and spacing in the captured images, achieving high accuracy without complex mechanical measurement systems.
Solution Approach 2:
The patent introduces an imaging device as an intermediary between the scattered components and the determination system. The imaging device captures visual information that is then processed to determine whether components can be held, serving as a mediator that translates physical component states into analyzable image data.
2Productivity
If the holding tool attempts to pick up all scattered components, then the productivity increases, but components may be missed due to inaccurate holdability determination
Solution Approach 1:
The patent implements a feedback mechanism where the imaging device continuously monitors the stage for scattered components, the control device determines holdability based on image analysis, and the holding tool executes pickup only when holdability is confirmed. This closed-loop feedback system ensures high productivity while maintaining reliability by preventing missed pickups.
3Measurement precision
If the imaging device captures detailed images of components, then the measurement precision of side surface size improves, but the processing time increases
Solution Approach 1:
The patent applies partial action by capturing images that provide sufficient detail for side surface size measurement without excessive detail. The imaging device is positioned and configured to capture the necessary component features for accurate measurement while avoiding unnecessary image processing of extraneous details, thus balancing precision with processing speed.
Data Source
AI summary
A loose component supply device in which components scattered on stage are imaged by camera. Because the viewing angle of the camera is α>0, a side surface of the component is imaged. Based on the image data of the component, an index value specifying a size of the side surface of the component is calculated. Then, in a case in which the calculated index value matches a set value, it is determined that it is possible to hold the component. In other words, in a case in which there is a certain distance between multiple components, from imaging a side surface of the component, if an index value that specifies the size of the side surface of the component matches the set value, it is determined that it is possible to hold the component.
