Multiaxial Robot Segmentation for Speed and Versatility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robots used in the 3C industries, such as SCARA and six-axis mechanical arms, face limitations in flexibility and efficiency, with SCARA being restricted to horizontal movements and six-axis arms being costly and inefficient for tasks requiring less than three-dimensional actions.
Innovation Solution
A multiaxial robot design incorporating a first rotation module with a base and arms rotating in a plane, a second rotation module with a wrist capable of rotating in a perpendicular plane, and an elevator member to enhance flexibility and operational range, allowing for up to six degrees of freedom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If SCARA robot is used for rapid positioning in X-Y plane, then positioning speed and rigidity are improved, but the robot is restricted to horizontal movements only and has short stroke in Z-direction
Solution Approach 1:
The robot system is divided into two functional modules: a SCARA module for rapid horizontal positioning and a six-axis mechanical arm module for three-dimensional movements. This segmentation allows each module to specialize in its optimal operation domain while working together to achieve both speed and versatility.
Solution Approach 2:
The patent combines the SCARA robot and six-axis mechanical arm into a single integrated system where the SCARA module handles rapid X-Y plane positioning and the six-axis module performs Z-direction and three-dimensional actions, merging the advantages of both robot types.
2Adaptability or versatility
If six-axis mechanical arm is used for three-dimensional actions, then flexibility and adaptability are improved, but the robot becomes slow and expensive
Solution Approach 1:
The system separates three-dimensional positioning tasks into two stages: rapid horizontal positioning by the SCARA module followed by precise three-dimensional adjustment by the six-axis module, reducing the need for the six-axis arm to perform slow horizontal movements.
Solution Approach 2:
The six-axis mechanical arm module is designed to handle multiple functions including three-dimensional positioning, gripping, and welding operations, making it a universal end-effector platform that works in conjunction with the SCARA module.
3Adaptability or versatility
If six-axis mechanical arm is used for tasks requiring less than three-dimensional actions, then versatility is improved, but efficiency and cost-effectiveness deteriorate
Solution Approach 1:
The system dynamically selects which module performs which task based on the requirements: SCARA module handles rapid horizontal positioning for high-speed tasks, while the six-axis module handles tasks requiring three-dimensional movements or complex orientations, optimizing productivity for each scenario.

AI summary
A multiaxial robot includes a first rotation module, a second rotation module, and a connecting member. The first rotation module includes a base and a plurality of arms. The arms are configured to rotate parallel to a first plane relative to the base. The second rotation module includes at least one wrist. The wrist is connected to the farthest arm arranged from the base in the first rotation module and configured to rotate parallel to a second plane relative to the first rotation module. The connecting member is pivotally connected to the base and connected to an adjacent one of the arms, or is connected between adjacent two of the arms and the wrist.
