Component Supply Device Stage Color Contrast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current component supply devices have limitations in accurately acquiring information about the position and orientation of components on a stage due to insufficient contrast and stability issues, especially with cylindrical components that may roll on flat stages.
Innovation Solution
The device addresses this by providing multiple types of stages that can be removably attached to the component support section, allowing for stages with different colors or textures to be used based on the component's color or shape, enhancing contrast and stability, such as using a black stage for white components or a grooved stage for cylindrical components to prevent rolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single type of stage is used for all components, then the device complexity is reduced, but the measurement precision of component position and orientation deteriorates when components have similar colors or require stability
Solution Approach 1:
The patent applies parameter changes by modifying the stage's surface properties (color, texture, pattern) to optimize contrast for different component types. Multiple stages with different parameters (white, black, textured, grooved) are prepared to enhance image recognition accuracy for components with varying characteristics.
Solution Approach 2:
The system dynamically selects and attaches the appropriate stage type based on the component being processed. The stage attachment mechanism allows rapid switching between different stage configurations to match the specific requirements of each component type, optimizing measurement precision without permanent complexity.
2Reliability
If a flat stage is used for cylindrical components, then the manufacturing precision is simplified, but the stability of the component deteriorates causing rolling
Solution Approach 1:
The patent applies local quality by adding grooves or textured patterns only in specific locations on the stage where cylindrical components are placed. This localized modification provides stability and prevents rolling without requiring the entire stage structure to be complex, maintaining ease of manufacture while improving reliability.
3Measurement precision
If a stage with the same color as the component is used, then the device complexity is reduced, but the measurement precision deteriorates due to poor contrast
Solution Approach 1:
The patent directly applies color changes by providing stages in different colors (white, black, etc.) to create maximum contrast with components of varying colors. This ensures clear visual distinction and accurate image recognition, with the control system automatically selecting the appropriate stage color based on the component being processed.

AI summary
A component supply device that images stage 226 on which multiple leaded components 410 are supported in a scattered state, and holds a component supported on the stage using a component holding tool based on the image data, wherein multiple stages of different colors are prepared, and a stage from among the multiple stages a stage with a color different to a component that is planned to be supplied is removably attached to component support member 220. By this, for example, in a case in which a component planned to be supplied is white, by attaching a black stage to the component support section, due to the contrast between the background and the target object, it is possible to clearly recognize the white component supported on the black stage. By this, it is possible to acquire with good accuracy information related to a position, orientation, and the like of a component on the stage based on the image data.
