Solution Overview

Problem

Existing work machines face difficulties in inserting wire members into complexly arranged insertion holes on circuit substrates, as they require individual movement of chucks to insert wire members into adjacent holes, making it challenging to manage complex configurations.

Innovation Solution

A work machine with two work heads and chucks that can move independently in the X, Y, and Z directions, allowing for alignment and insertion of wire member end portions into corresponding connecting sections on the circuit substrate, even when these sections are complexly arranged.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a pair of chucks individually moves to insert wire members into adjacent insertion holes, then simple adjacent hole insertion is achieved, but complexly arranged insertion holes cannot be handled

Engineering Contradiction:
Improvecapability to handle complexly arranged insertion holesVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The work head is divided into two independent chucks (first chuck and second chuck), each capable of independently moving in the up-down direction. This segmentation allows each chuck to individually position and insert wire members into different insertion holes, enabling handling of complexly arranged holes while maintaining manageable device complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The chucks are designed with dynamic movement capability, rotating around a rotation axis to change their positional relationships. The first and second chucks can independently move up and down, and rotate to different angular positions, allowing adaptive positioning for various insertion hole arrangements on the circuit board

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple chucks move independently to handle complex arrangements, then versatility is improved, but control complexity increases

Engineering Contradiction:
Improveflexibility in handling various hole arrangementsVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Both chucks share the same structural design and movement mechanism, allowing them to perform identical functions independently. This universality simplifies the control system as both chucks can be controlled using the same control logic, reducing overall control complexity while maintaining high versatility for different insertion patterns

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The second chuck is essentially a copy of the first chuck in terms of structure and functionality. This copying approach allows the control system to use standardized control programs for both chucks, reducing the complexity of controlling multiple independent units while achieving flexible positioning for complex hole arrangements

Inventive Principle:
Principle #26Copying
