Robot Tool Driving Module for Dynamic Axis Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robot manipulators with articulated arms have limited tool working ranges due to fixed tool positions, restricting applicability and efficiency, especially in first- and second-type manipulators, while third-type manipulators require manual adjustment, complicating use and reducing efficiency.
Innovation Solution
A tool driving module that automatically rotates the tool to align its center point with the end-shaft axis, using a motor-driven mechanism with a connection part, driving arm, and tool fixing bracket, allowing detachable connection to the articulated arm without altering the original structure, enabling broader tool working ranges and easy tool replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the tool is directly connected with the end-shaft of the articulated arm, then the structure is simple, but the work position of the tool cannot be changed and the working range is limited
Solution Approach 1:
The patent introduces a driving mechanism that enables the tool to rotate dynamically around the end-shaft axis, transforming the static connection into a dynamic adjustable system. This allows the tool work position to be changed while maintaining relative simplicity in the overall structure.
Solution Approach 2:
The patent divides the tool connection system into separate components: the tool, the tool holder, and the driving mechanism. This segmentation allows independent adjustment of the tool position and orientation without complicating the entire end-shaft structure.
2Device complexity
If the tool module is connected with the end-shaft and the work position is fixed, then the structure is simple, but the working range of the tool is limited
Solution Approach 1:
The patent equips the tool module with a driving mechanism that enables automatic rotation and position adjustment, transforming the fixed work position into an adjustable one, thereby expanding the working range without significantly increasing structural complexity.
3Adaptability or versatility
If the inclination angle of the tool is adjusted by hand, then the work position can be changed, but the complexity of use increases and production efficiency is reduced
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated driving mechanism that uses motor control to adjust the tool inclination angle and work position, thereby reducing operation complexity and improving production efficiency.
Solution Approach 2:
The driving mechanism enables the tool module to self-adjust its position and orientation automatically based on control signals, eliminating the need for manual intervention and complex operational procedures.
4Adaptability or versatility
If various robot manipulators are developed to solve the problems, then the working range is extended, but the cost increases
Solution Approach 1:
The patent designs a universal tool module with a standardized driving mechanism that can be attached to existing robot manipulators, enabling one tool module design to serve multiple applications and reducing overall system cost compared to developing separate manipulators for each function.
Solution Approach 2:
The patent separates the tool module from the robot manipulator body, allowing the tool to be independently designed, manufactured, and replaced without affecting the main robot structure, thereby reducing costs associated with developing and modifying entire manipulator systems.
