Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot systems face challenges in efficiently performing workpiece transfer tasks while moving, as they require stationary conditions for accurate image taking and operation, leading to increased cycle times and reduced flexibility.
Innovation Solution
A robot system comprising a robot mounted on a movable object with a camera that takes images of reference objects while moving, allowing the robot to operate on workpieces based on these images, enabling continuous correction of teaching data for precise positioning and posture adjustments during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the robot system stops the movable object at a predetermined teaching position to take images and perform work, then the image taking accuracy and work precision are improved, but the cycle time increases and productivity decreases
Solution Approach 1:
The patent applies the dynamics principle by enabling the robot system to perform image taking and work operations while the movable object is in motion, rather than requiring it to stop. The camera and robot are mounted on the movable object, allowing them to capture images and manipulate workpieces during movement. This dynamic operation eliminates the need for stopping, thereby maintaining measurement precision while significantly improving productivity by reducing cycle times.
2Manufacturing precision
If the robot system stops the movable object at a predetermined teaching position to perform work, then the work precision is improved, but the operational flexibility is reduced
Solution Approach 1:
The system enables dynamic work operations where the robot can manipulate workpieces while the movable object is moving, allowing the system to adapt to various operational scenarios without requiring predetermined stopping positions. This enhances operational flexibility while maintaining work precision through real-time image guidance and continuous positioning correction.
Solution Approach 2:
The camera and robot mounted on the movable object perform self-guided operations by continuously capturing images of reference objects and adjusting their positions relative to workpieces during movement. This self-service capability allows the system to maintain precision while adapting to different work scenarios without external intervention or predetermined stopping points.
3Measurement precision
If the robot system requires stationary conditions for image taking and operation, then the measurement accuracy is improved, but the cycle time increases
Solution Approach 1:
The patent implements continuous useful action by enabling the camera to continuously capture images of reference objects and the robot to continuously perform work operations while the movable object is in motion. This eliminates idle stopping time and maintains measurement accuracy through continuous image acquisition and real-time processing, thereby significantly reducing cycle time while preserving measurement precision.
