Picking Head 3D Imaging Synchronized With Conveyor Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional picking devices struggle to accurately acquire three-dimensional information of moving workpieces due to blur caused by the time required for three-dimensional imaging, limiting their ability to sort and recover disassembled or crushed products with precision.
Innovation Solution
A picking device that synchronizes a three-dimensional imaging device with the transport speed of the workpieces using a movement mechanism, allowing it to capture images in synchronization with the transport direction, thereby reducing blur and enabling accurate three-dimensional information acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a three-dimensional imaging device is used to capture moving workpieces, then three-dimensional information can be obtained, but movement blur occurs due to the time required for imaging
Solution Approach 1:
The imaging device is made movable and synchronized with the transport speed of workpieces. By dynamically adjusting the imaging device's movement to match the conveyor belt speed, the relative position between the imaging device and workpieces remains constant during imaging, eliminating blur while capturing three-dimensional information
Solution Approach 2:
The system uses feedback from the transport speed information to control the imaging device's movement. The imaging device receives real-time speed data from the conveyor system and adjusts its own movement accordingly, ensuring synchronous operation and maintaining image clarity throughout the imaging process
2Measurement precision
If the imaging time is extended to capture three-dimensional data, then measurement accuracy improves, but productivity decreases due to slower imaging speed
Solution Approach 1:
The imaging process operates continuously without interruption by moving the imaging device synchronously with the conveyor. This eliminates the need to stop the conveyor for imaging, maintaining continuous workpiece transport and imaging simultaneously, thus preserving productivity while achieving accurate three-dimensional capture
