Solution Overview

Problem

Conventional component mounting devices require complex device structures due to the need for dedicated substrate transfer devices, which increases complexity and reduces flexibility in transferring mounting targets.

Innovation Solution

A component mounting device with a conveyance unit, a head unit that can move horizontally to hold and transfer components, and a controller that manages the head unit's movement to transfer the mounting target to a different position, eliminating the need for a dedicated transfer device by using the head unit for both component mounting and transfer operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a dedicated substrate transfer device is provided to transfer the substrate from the substrate conveyance device to the substrate holder, then the substrate can be transferred between different positions, but the device structure becomes complex

Engineering Contradiction:

Improvedevice structureVSAvoidtransfer capability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The head unit is designed to perform multiple functions: it can hold components for mounting operations and simultaneously hold the placement member for transfer operations. This multi-functionality eliminates the need for a dedicated transfer device, reducing device complexity while maintaining transfer capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The transfer function is merged with the mounting function by using the same head unit for both operations. The head unit combines component holding capability with placement member holding capability, integrating two previously separate functions into one unified system.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If the head unit holds the placement member to transfer the mounting target, then the degree of freedom in selecting holding positions is improved, but the risk of positional deviation and fall increases

Engineering Contradiction:

Improveholding position selectionVSAvoidpositional accuracy

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The head unit includes multiple heads that can independently hold the placement member at different positions. This segmentation allows flexible selection of holding positions while distributing the holding load across multiple points, reducing the risk of positional deviation and fall.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The placement member acts as an intermediary between the head unit and the mounting target. By holding the placement member rather than directly holding the mounting target, the system gains flexibility in holding position selection while the placement member provides stable support to prevent positional deviation and fall.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A component mounting device includes a conveyance unit that conveys a placement member on which a mounting target is placed, a head unit movable in a horizontal plane, and a controller. The controller transfers the mounting target from the conveyance unit to a transfer position by controlling movement of the head unit in the horizontal plane in a state in which the placement member is held by one or a plurality of heads of the head unit.
