Component Mounting Imaging Control with Shared Lighting Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting devices require multiple imaging sessions under different lighting conditions for components spanning multiple classification categories, leading to prolonged production time.
Innovation Solution
Defining imaging conditions as a range of values rather than a single optimum value, allowing for shared imaging conditions among components with different ranges, thereby reducing the number of imaging sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple imaging sessions are performed under different lighting conditions for components spanning multiple classification categories, then accurate recognition of components is achieved, but production time is prolonged
Solution Approach 1:
The patent applies parameter changes by defining imaging conditions as ranges rather than fixed values. Multiple lighting conditions are consolidated into unified imaging condition ranges that can accommodate different component types, allowing the imaging system to capture multiple components in a single session without sacrificing recognition accuracy.
Solution Approach 2:
The patent implements universality by creating imaging condition ranges that serve multiple component classification categories simultaneously. Instead of having separate imaging conditions for each component type, a single imaging condition range can cover multiple categories, enabling the imaging section to handle diverse components without requiring multiple specialized imaging sessions.
2Manufacturing precision
If imaging conditions are defined as a single optimum value, then precise imaging control is achieved, but the number of imaging sessions increases when holding components with different imaging conditions
Solution Approach 1:
The patent transforms imaging conditions from fixed single values to ranges of values. This parameter change allows the system to maintain precise imaging control within the defined range while accommodating variations between different components. The range-based approach enables multiple components with different optimal conditions to be imaged under a single unified condition set.
Solution Approach 2:
The patent segments the imaging condition space into ranges that can encompass multiple component types. By dividing the parameter space into manageable ranges rather than treating each component individually, the system can group components that share overlapping imaging condition ranges, reducing the total number of imaging sessions required.

AI summary
A mounting device provided with: a collecting section configured to move a component for which imaging conditions are defined as a range including multiple values to an arrangement position in a state with multiple of the components collected; an imaging section configured to image the multiple components held by the collecting section; and a control section configured to, when the collecting section is holding the multiple components that include imaging conditions with ranges that are not the same, cause the imaging section to image the multiple components using imaging conditions with a shared value among the ranges defined for the multiple components held by the collecting section.
