Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot systems face challenges in achieving a balanced size and movable range, where downsizing the work robot to save space results in a reduced ability to cover the entire workpiece range, leading to incomplete coating or operation inefficiencies.
Innovation Solution
A robot system configuration that includes a work robot with a support member connecting it to the workpiece supplier, where the robot arm is turnable about a crossing axis, optimizing the robot's position and posture to match the workpiece range, ensuring complete coverage and efficient operation while maintaining a compact system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the work robot is downsized to save space, then the system size is reduced, but the movable range is reduced leading to incomplete coating coverage
Solution Approach 1:
The robot arm is configured to rotate about an axis that crosses the workpiece turning axis, adding a dimensional crossing relationship between the robot arm movement and workpiece rotation. This spatial arrangement allows a compact robot to access the entire workpiece surface area even when the workpiece rotates, effectively expanding the movable range without increasing robot size.
2Device complexity
If the robot arm turning axis is aligned parallel to the workpiece turning axis, then the structure is simplified, but the robot cannot cover the entire workpiece range efficiently
Solution Approach 1:
Instead of aligning the robot arm turning axis parallel to the workpiece turning axis, the invention positions them to cross each other at a specific angle. This asymmetric crossing configuration optimizes the robot's ability to cover the workpiece surface area, improving coating completeness and operational efficiency while maintaining reasonable structural complexity.

AI summary
A robot system includes a workpiece supplier, a work robot, and a support. The workpiece supplier is to turn a workpiece about a workpiece turning axis to position the workpiece at a work position. The work robot includes a base and a robot arm. The robot arm is connected to the base turnably about an arm turning axis to perform a work on the workpiece at the work position. The arm turning axis crosses the workpiece turning axis. The support connects the workpiece supplier and the base.
