Solution Overview

Problem

Existing electronic circuit component mounting systems face inefficiencies in mounting operations due to the need to move mounting devices to multiple feeders and simultaneous loading and preparation processes, which can lead to reduced operational efficiency and increased deviation during component placement.

Innovation Solution

An electronic circuit component mounting system that uses a mounting head with multiple nozzle holders and a head-side feeder system, where the component holding tool contacts the component at a pickup position and the circuit substrate during mounting, optimizing the component reception order and simultaneous mounting of tape and bulk components to improve efficiency and reduce deviation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple bulk feeders are used to supply electronic circuit components, then component supply capacity is improved, but the mounting device must move to each feeder which reduces mounting operation efficiency

Engineering Contradiction:
Improvecomponent supply capacityVSAvoidmounting operation efficiency
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

Multiple bulk feeders are merged into a single integrated head-side feeder that is positioned on the mounting head. This allows multiple component types to be supplied from one location, eliminating the need for the mounting device to move between multiple separate feeders while maintaining the capacity to supply various electronic circuit components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The feeder system is transitioned from a main-body-side configuration to a head-side configuration, changing the spatial dimension of component supply. By positioning the feeder on the mounting head itself, the system enables simultaneous access to multiple component types without requiring lateral movement between feeders.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If simultaneous loading and mounting preparation operations are performed, then operational efficiency is improved, but device complexity increases

Engineering Contradiction:
Improveoperational efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system enables continuous operation by performing board loading and mounting preparation simultaneously. While the board is being loaded onto the mounting head, the mounting preparation operations are conducted in parallel, ensuring that no time is wasted and the mounting process flows continuously without interruption.

Inventive Principle:
Principle #20Continuity of useful action

3Manufacturing precision

If the component holding tool contacts the component at pickup position and the substrate during mounting, then mounting precision is improved, but the need for device movement increases

Engineering Contradiction:
Improvemounting precisionVSAvoidmounting operation efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The component pickup and mounting functions are extracted and integrated into the mounting head, eliminating the need for separate pickup and mounting operations. The component holding tool is positioned to contact the component at the pickup position and then directly place it on the substrate, reducing intermediate movements while maintaining precision through controlled contact points.

Inventive Principle:
Principle #2Taking out (Extraction)
