Robot Arm Takeout System Parallel Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional workpiece takeout systems require the robot arm to be deactivated each time a workpiece is taken from a different stocker, elongating the time required for sequential takeout operations from multiple stockers.
Innovation Solution
The robot arm performs workpiece takeout operations simultaneously with the disposed-state detector's detection of another workpiece's state in a different area, eliminating the need for deactivation and reducing the overall time for sequential takeout processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the robot arm is deactivated for the disposed-state detector to detect workpiece states in another stocker, then the detection accuracy is ensured, but the tact time for sequential takeout operations is elongated
Solution Approach 1:
The disposed-state detector performs detection of workpiece states in advance or concurrently with the robot arm's takeout operation, rather than sequentially. This allows the detection to be prepared beforehand or overlap with the robot's movement, eliminating the need to stop the robot for detection and thus reducing tact time while maintaining detection accuracy
Solution Approach 2:
The system enables continuous operation by allowing the robot arm to perform takeout operations without interruption while the disposed-state detector simultaneously detects workpiece states in other stockers. This parallel execution eliminates idle time and maintains continuous productive action throughout the sequential takeout process
2Productivity
If the robot arm operates continuously without deactivation, then the productivity is improved, but the disposed-state detector cannot accurately detect workpiece states
Solution Approach 1:
The disposed-state detector captures workpiece state information in advance or concurrently with the robot arm's operation, preparing detection data before it is needed for the next takeout operation. This ensures accurate detection without requiring the robot to stop, maintaining both productivity and detection accuracy
Solution Approach 2:
The system achieves continuous productive action by running the robot arm and disposed-state detector in parallel. The detector continuously monitors workpiece states in other stockers while the robot performs takeout operations, ensuring neither function interrupts the other and both maintain their respective performance levels
