Component Mounter Holding Body Rotation for Side Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In component mounting systems, imaging a picked-up component from the side often results in improper orientation, leading to suboptimal imaging due to the component not being aligned in a preferred direction during the imaging process.
Innovation Solution
The component mounter alternately performs component pickup and holding body revolving processes, adjusting the component's holding angle to a detection angle suitable for imaging by rotating the holding bodies on their axes, ensuring accurate orientation and detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the component is picked up and imaged from the side without rotation, then the imaging process is simple and fast, but the component orientation is unpredictable and often improper for detection
Solution Approach 1:
The holding bodies are made rotatable on their axes to dynamically adjust component orientation. The rotation mechanism allows the holding bodies to change from a static pickup orientation to a dynamic detection orientation, enabling the component to be properly aligned for side imaging while maintaining the simplicity of the pickup process.
Solution Approach 2:
The component holding angle is changed as a parameter to optimize detection. By rotating the holding bodies, the component orientation angle is adjusted from the pickup angle to a detection angle that is suitable for side imaging, thereby improving measurement precision without complicating the overall system.
2Measurement precision
If the holding bodies rotate on their axes to adjust component orientation, then the component can be properly oriented for detection, but the processing time increases due to the additional rotation step
Solution Approach 1:
The holding bodies perform periodic rotation at specific intervals in the process flow. Rather than continuous rotation, the system uses discrete periodic rotation actions to adjust component orientation only when needed for detection, minimizing time loss while ensuring proper imaging quality.
Solution Approach 2:
The rotation of holding bodies is performed in advance before the imaging detection step. By preliminarily adjusting the component orientation to the detection angle before imaging occurs, the system ensures proper imaging quality without requiring time-consuming adjustments during the detection process itself.

AI summary
A component mounter of the present disclosure includes a mounting head having multiple holding bodies, a revolving mechanism configured to revolve the multiple holding bodies along a revolution trajectory, a rotating mechanism configured to cause the multiple holding bodies to rotate on their axes in synchronism with each other, a detection section configured to detect a component located in one or more component detection positions which are different from the component pickup positions on the revolution trajectory from a side thereof; and a control section. The control section performs component pickup processing for causing the mounting head to cause at least one of the holding bodies located in the component pickup position to pick up and hold the component and holding body revolving processing for causing the revolving mechanism to locate the holding body that does not hold the component in the position of the holding body that picks up the component during the component pickup processing alternately and repeatedly. In executing the holding body revolving processing, the control section performs holding body rotating processing for causing the rotating mechanism to change a component holding angle of a component held to at least one of the holding bodies located in the component detection position through a current holding body revolving processing to a detection angle that differs from the component holding angle of the component when the component is picked up.
