Rocking Workpiece Holder for Multi-Surface Component Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounted body manufacturing systems for three-dimensionally shaped workpieces have complex configurations due to multiple degrees of freedom in workpiece posture adjustment and mounting on multiple surfaces, leading to a complicated setup.
Innovation Solution
A system with a first and second positioning mechanism that rocks a workpiece holder around a lateral axis to align and change the posture of a workpiece, allowing for simple mounting of components on multiple surfaces using applicators and mounters with integrated posture changers, reducing the complexity by using a transport mechanism to move the workpiece holder between positioning stages.

1Adaptability or versatility
If multiple degrees of freedom are used for workpiece posture adjustment and mounting on multiple surfaces, then the system can handle three-dimensional workpieces effectively, but the configuration becomes complex
Solution Approach 1:
The system divides the workpiece holder into multiple independent positioning mechanisms, each responsible for a specific mounting surface. The first positioning mechanism handles the first mounting surface while the second positioning mechanism handles the second mounting surface, allowing each mechanism to be simpler and more specialized rather than requiring one complex mechanism to handle all surfaces
Solution Approach 2:
The system adds a transport mechanism that moves the workpiece holder between different positioning mechanisms in the vertical dimension. This allows the workpiece to be presented to different positioning mechanisms at different heights, enabling multi-surface mounting without requiring all positioning mechanisms to operate simultaneously in the same space, thus reducing overall system complexity

AI summary
When a workpiece holder holding a workpiece is rocked around a lateral rocking axis by a work stage of a mounter and the workpiece is positioned so that one mounting surface of the workpiece faces a predetermined direction to be worked, a component is mounted on the one mounting surface by a mounting head of the mounter. When a posture of the workpiece in the workpiece holder is changed by a posture changing head of a posture changer and thereafter the workpiece holder in which the posture of the workpiece is changed is rocked around the lateral rocking axis by the work stage of the mounter and the workpiece is positioned so that the other mounting surface of the workpiece faces a predetermined direction to be worked, a component is mounted on the other mounting surface by the mounting head of the mounter.
