Dual-Robot Workpiece Holder Auto-Exchange Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot-assisted processing systems require significant user intervention during changeover operations, which slows down processing speed and increases the need for personnel, while lacking flexibility to handle diverse workpieces efficiently.
Innovation Solution
An apparatus comprising two cooperating robots that automatically replace workpiece holders during processing operations, allowing the robots to handle and process multiple workpieces with minimal user intervention, and featuring a tool changer for tool exchange, enabling flexible handling and processing of various workpieces without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual replacement of workpiece holders is used during changeover operations, then personnel can directly exchange holders, but processing speed decreases and personnel requirements increase
Solution Approach 1:
The system performs self-service during changeover operations by automatically replacing workpiece holders using the robot itself, eliminating the need for external personnel intervention. The robot autonomously executes the replacement sequence, making the system serve itself during transitions between different workpiece types.
Solution Approach 2:
The control unit acts as an intermediary that coordinates the robot's actions during changeover. It manages the automated replacement process by sending controlled movements to the robot, serving as a mediator between the automation system and the changeover operation.
2Adaptability or versatility
If multiple different workpieces are processed, then flexibility increases, but changeover operations require more manual intervention
Solution Approach 1:
The robot is designed with multi-functionality to handle various workpiece holders through automated replacement. The same robot system serves multiple functions by automatically adapting to different workpiece types, eliminating the need for specialized manual procedures for each workpiece variant.
3Productivity
If automated workpiece holder replacement is implemented, then processing speed increases and personnel requirements decrease, but system complexity increases
Solution Approach 1:
The system merges the workpiece holder replacement function with the robot's existing handling capabilities. By integrating the replacement operation into the robot's normal workflow rather than adding a separate dedicated mechanism, the system achieves automation without proportionally increasing overall complexity.

AI summary
A first robot for handling at least one first workpiece in a first processing operation of the apparatus, a second robot cooperating with the first robot for processing the at least one first workpiece in the first processing operation, and at least one first workpiece holder for holding the at least one first workpiece during the first processing operation. In order to improve robot-assisted processing of workpieces which differ from one another, the first robot handles at least one second workpiece and the second robot processes the at least one second workpiece in a second processing operation of the apparatus. The first robot or the second robot in order, in a changeover operation of the apparatus, to replace the at least one first workpiece holder automatically by at least one second workpiece holder for holding the at least one second workpiece during the second processing operation.
