Dual Chuck Work Head for Complex Circuit Substrate Wire Mounting
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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
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
2Adaptability or versatility
If multiple chucks move independently to handle complex arrangements, then versatility is improved, but control complexity increases
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
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

AI summary
A work machine and a mounting method by which end portions of a wire member can be mounted on connecting sections which are arranged variously are provided. A work head includes a first holding section configured to hold a first end portion and a second holding section configured to hold a second end portion. A control device includes a first mounting section configured to mount the first end portion held by the first holding section on a first connecting section, a moving section configured to cause a work head moving device to move the work head in accordance with a position of the second connecting section after having mounted the first end portion on the first connecting section, and a second mounting section configured to mount the second end portion held by the second holding section on a second connecting section.
