Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting devices do not account for the determination of the supply state of components from a component supply device during the mounting process, specifically in terms of rotational alignment, which is crucial for accurate inspection and mounting.
Innovation Solution
A component mounting device that includes a head for picking up components, an imaging device for capturing images, and a control device that creates recognition data by obtaining angle information about the component's supply angle and rotating the captured image to a reference angle, allowing for the determination of the component's supply state and subsequent accurate pickup and mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image recognition data is created in advance with component direction aligned to reference direction, then recognition accuracy for mounting state inspection is improved, but the process does not account for component supply angle variations causing mounting errors
Solution Approach 1:
The patent applies dynamics by making the image capture frame rotatable to match the actual supply angle of components. Instead of using a fixed reference direction, the system dynamically adjusts the capture frame's orientation based on detected supply angles, allowing the recognition process to adapt to varying component supply orientations while maintaining recognition accuracy
Solution Approach 2:
The patent changes the parameter of image capture frame orientation from a fixed reference direction to a variable angle that matches the actual supply angle. By adjusting the capture frame's rotational parameter based on detected supply angles, the system maintains recognition accuracy across different component supply orientations
2Reliability
If separate processes are used for creating recognition data and determining supply state, then comprehensive inspection is achieved, but process complexity increases
Solution Approach 1:
The patent merges the recognition data creation process with the supply state determination process into a single integrated workflow. The same captured images are used for both creating the rotationally-adjusted recognition data and determining the supply state, eliminating the need for separate inspection processes while maintaining comprehensive reliability
Solution Approach 2:
The patent creates a multi-functional recognition data that serves dual purposes: it is used for both mounting state inspection and supply state determination. The rotationally-adjusted image capture frame enables the same recognition data to verify both the correct mounting orientation and the proper supply angle, reducing process complexity
Data Source
AI summary
A component mounting device includes a control device configured to execute a recognition data creation process and a pickup process. In the recognition data creation process, the control device creates the recognition data by obtaining the angle information of the component, causing the imaging device to operate so as to image the component, and rotating the captured image so obtained to the reference angle based on the angle information. In the pickup process, the control device causes the head to operate so as to pick up the component after the supply state of the component is determined based on the captured image obtained by causing the imaging device to operate so as to image the component, the recognition data created in the recognition data creation process, and the angle information.
