Workpiece Supply Robot Segmented Gripper Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bending robots require changing grippers for different workpiece sizes and shapes, limiting expendability due to the need for sensors and mechanisms on all grippers, restricting configuration and increasing complexity.
Innovation Solution
A workpiece supply robot with a permanent robot hand and an extending robot hand that can be removable, allowing partial extension without the restrictions of a common configuration, and a storage unit for the extending robot hand on the workpiece placement platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional auto gripper changer with multiple grippers is used, then different workpiece sizes and shapes can be handled, but the configuration is restricted and complexity increases due to sensors and mechanisms needing to be mounted on all grippers
Solution Approach 1:
The robot hand is divided into a permanent robot hand and a separate extending robot hand that can be attached or removed. This segmentation allows the permanent hand to maintain a simple, standardized configuration while the extending hand provides additional functionality only when needed, reducing overall system complexity.
Solution Approach 2:
The permanent robot hand is designed with a universal interface that can accommodate different extending robot hands for various workpiece types. This multi-functionality approach allows a single permanent hand structure to serve multiple purposes by combining with different extending hands, eliminating the need for sensors and mechanisms on all possible grippers.
2Adaptability or versatility
If the robot hand is made extendable to handle various workpiece sizes, then versatility improves, but configuration restrictions are imposed by common gripper designs
Solution Approach 1:
By separating the robot hand into permanent and extending components, the design achieves extendability without being constrained by the need for a single common gripper configuration. The permanent hand provides the base functionality while the extending hand adds capability for larger workpieces, maintaining operational flexibility.
Solution Approach 2:
The robot hand transitions from a static, fixed configuration to a dynamic, adaptable structure where the extending robot hand can be attached or removed based on the workpiece requirements. This dynamic configuration allows the system to adapt to different workpiece sizes without being restricted by a predetermined common gripper design.
3Adaptability or versatility
If multiple grippers with sensors and mechanisms are used, then workpiece handling capability is improved, but downtime increases due to installation and removal operations
Solution Approach 1:
The separation of the permanent robot hand from the extending robot hand enables quick attachment and removal of the extending component without affecting the permanent structure. This segmentation reduces downtime by allowing only the extending hand to be exchanged rather than replacing entire gripper assemblies with sensors and mechanisms.
