Solution Overview

Problem

When picking up components in a lined up state, adjacent components often get lifted unintentionally, leading to mounting errors due to contact during the pickup process.

Innovation Solution

A component pickup method involving a holding device that moves a specified distance towards an adjacent component and then in the opposite direction to create a gap before raising the component, preventing adjacent components from being lifted.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a component is picked up while contacting an adjacent component, then the pickup process is simple and fast, but the adjacent component may be lifted up unintentionally causing mounting errors

Engineering Contradiction:
Improvepickup speedVSAvoidmounting accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The component holding device performs preliminary actions by moving in the first direction toward the adjacent component and then in the opposite direction before raising the component. This preliminary movement creates a gap between the picked-up component and adjacent components, preventing unintentional lifting of adjacent components during the pickup process.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the component holding device moves towards adjacent component and then in opposite direction, then adjacent components are prevented from being lifted, but the pickup process becomes more complex

Engineering Contradiction:
Improvemounting accuracyVSAvoidpickup process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The component holding device employs dynamic movement by changing direction during the pickup process. It moves in a first direction toward the adjacent component, then reverses to move in the opposite direction, creating a gap before final raising. This dynamic approach ensures reliable pickup while maintaining manageable process complexity through systematic motion control.

Inventive Principle:
Principle #15Dynamics

AI summary

A method for suitably picking up a component supplied in a lined up state. The component that is at pickup position is held using component holding device; and while holding the component with the component holding device, the component holding device is moved specified distance in a direction towards a component adjacent to the held component, then the component holding device is moved specified distance in a direction opposite to the first direction, and then the component holding device is raised.
