Robot Seal Belt Inner Outer Sections Dust-Proofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robots, including substrate conveying robots, face inadequate dust-proofing, leading to particle release and corrosion from corrosive gases, which reduces their lifespan.
Innovation Solution
A robot design featuring a seal belt with inner and outer belt sections that cover the opening, combined with a drive mechanism and intake mechanism to prevent particle release and gas entry, enhancing dust-proofing and preventing corrosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single shield film is used to cover the opening, then the structure is simple, but the dust-proof effect is insufficient and corrosive gas can penetrate through
Solution Approach 1:
The seal belt is divided into an inner belt section and an outer belt section, creating a multi-layer sealing structure. The inner belt section provides primary sealing close to the opening, while the outer belt section provides secondary sealing, together forming a more reliable dust-proof barrier that prevents both particles and corrosive gases from penetrating through.
Solution Approach 2:
The inner belt section is positioned within the outer belt section, creating a nested configuration where the inner section is closer to the opening and the outer section provides additional protection. This nested arrangement enhances the dust-proof effect by creating multiple barriers that corrosive gas and particles must penetrate.
2Reliability
If the belt is fixed rigidly to prevent movement, then sealing is improved, but particle generation from scraping increases
Solution Approach 1:
The seal belt is designed to be movable rather than rigidly fixed, allowing it to dynamically adjust its position as the movable member moves in and out. The belt can flex and shift to maintain contact with the casing opening, ensuring continuous sealing performance without generating excessive particles from rigid scraping.
Solution Approach 2:
The seal belt is constructed as a flexible element that can deform and adapt to the movement of the movable member. This flexibility allows the belt to maintain effective sealing contact with the casing opening while reducing friction and particle generation compared to rigid sealing structures.
3Reliability
If the belt extends beyond the movable member range, then dust-proofing is improved, but the belt length increases
Solution Approach 1:
The seal belt is segmented into an inner belt section that extends beyond the movable member's travel range to ensure continuous coverage of the opening, and an outer belt section that provides additional sealing. This segmentation allows the critical inner section to be sufficiently long for dust-proofing while the outer section can be optimized separately.
Solution Approach 2:
The inner belt section is designed with greater length extension beyond the movable member range compared to the outer belt section, concentrating the additional length where it is most needed for dust-proof coverage at the opening, while the outer section can be shorter as it provides secondary sealing further from the critical opening area.

AI summary
A seal belt includes inner and outer belt sections. The inner belt section revolves according to the movable member movement. The outer belt section includes, between the inner belt section and an opening, a first portion in which a first end is retained at a movable member inside section portion, the portion being closer to the opening lower end, and the remaining portion extends along the opening and is retained at a third space position, and a second portion in which a first end is retained at an inside section portion, the portion being closer to the lower end, and the remaining portion extends to a fourth space position along the opening and is retained at the fourth space position. The first portion and second portions lengths are changed in a complementary manner according to the movable member movement. The drive mechanism is surrounded by the inner belt section.
