Industrial Robot Base Coupling Frame Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial robots used in production lines for testing optical and electronic devices face challenges in reducing vibration impacts during operations, leading to elongated cycle times and reduced accuracy due to the high cost and positioning limitations of vibration isolation mechanisms, and issues with base installation accuracy when bases are spatially separated.
Innovation Solution
An industrial robot system comprising a first base supporting the robot main body, a second base for work placement, and a coupling frame that integrates these bases via their bottom portions, elongating the vibration transmission pathway and enhancing installation accuracy by fixing the second base to the floor with anchor bolts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a vibration isolation mechanism is installed in the transfer robot or test unit, then vibration transmission to works is reduced, but the mechanism itself is expensive and reduces positioning accuracy
Solution Approach 1:
The patent extracts the vibration isolation function from the robot or test unit and relocates it to the base structure. By providing a vibration isolation mechanism between the base and the floor surface, the harmful vibrations are isolated at the source without interfering with the positioning accuracy of the robot arm or workpiece handling operations.
2Object-affected harmful factors
If two bases are spatially separated to reduce vibrations, then camera vibrations are reduced, but installation accuracy and workability deteriorate
Solution Approach 1:
The patent merges the first base (supporting robot) and second base (supporting worktable) into a single integrated base structure. This unified base is then positioned as one unit on the floor surface with proper alignment, ensuring high installation accuracy while still maintaining vibration isolation through the mechanism between the base and floor.
