Robot Joint Sealing Structure for Dust- and Moisture-Proof Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots, particularly multi-joint arms, face challenges in durability, dust-proofing, and moisture-proofing, which affect their performance and longevity.
Innovation Solution
A robot design featuring a first arm, a second arm rotatably joined to the first arm, a sealing member between the arms, and a joint block to cover and join the arms, enhancing assembly convenience and structural stability while providing dust and moisture protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-joint arm structure is used to enable robot flexibility and movement, then the robot's operational capability is improved, but the durability and protection against dust and moisture deteriorate due to exposed joints and multiple connection points
Solution Approach 1:
The joint block is nested within the joint structure, covering the sealing member and connecting the first and second arms. This nested configuration protects the internal sealing components while maintaining the multi-joint arm's flexibility and movement capability.
Solution Approach 2:
A sealing member is introduced as a flexible protective element between the first arm and second arm. The sealing member forms a protective barrier that prevents dust and moisture ingress while allowing the joint to maintain its rotational flexibility and operational range.
2Device complexity
If traditional joining methods are used for multi-joint arms, then the structure is simpler, but the assembly convenience and structural stability deteriorate
Solution Approach 1:
The joining structure is segmented into distinct functional components: a joint block for mechanical connection, and a sealing member for protection. This segmentation allows each component to perform its specific function optimally while simplifying the overall assembly process through modular installation.
Solution Approach 2:
The joint block serves as an intermediary component that facilitates the connection between the first arm and second arm. It provides a standardized interface that simplifies assembly while the integrated sealing member ensures structural stability and environmental protection.
3Ease of operation
If joints are exposed in multi-joint arms, then the structure is more open and accessible, but the dust-proof and moisture-proof performance deteriorate
Solution Approach 1:
The sealing member acts as a flexible protective film or shell that covers the joint interface between the first and second arms. It maintains dust-proof and moisture-proof performance while allowing the joint to remain accessible for operation and maintenance through its flexible design.
Solution Approach 2:
The sealing member is nested within the joint block structure, creating a protective envelope around the joint interface. This nested configuration shields the joint from dust and moisture while maintaining the overall accessibility of the multi-joint arm system.
