Brush Cleaning Roller Assembly for Substrate Rotation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scrubber boxes in electronic device manufacturing lack effective support and control for substrate rotation during cleaning, leading to reduced throughput and shorter roller assembly lifespan, necessitating a more robust and durable solution.
Innovation Solution
A roller assembly with a washer assembly featuring an annular groove and compressible materials to securely grip substrates, allowing precise control over rotation and reducing slippage, while also being easily replaceable and cost-effective.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional roller assemblies are used to support substrate rotation, then the cleaning process can be performed, but the substrate rotation control is insufficient leading to slippage and reduced throughput
Solution Approach 1:
The washer assembly incorporates an annular groove with compressible material specifically at the substrate contact region, providing localized enhanced grip and rotation control where needed, while the rest of the roller assembly maintains its structural function
Solution Approach 2:
The washer assembly uses a composite structure combining rigid washer bodies with compressible material inserts in the annular groove, creating a hybrid material system that provides both structural support and compliant substrate gripping capability
2Duration of action of stationary object
If traditional roller assemblies are used, then the cleaning process can proceed, but the roller assembly lifespan is reduced requiring frequent replacement
Solution Approach 1:
The compressible material in the annular groove provides dynamic adaptation to substrate thickness variations, maintaining optimal contact pressure and grip throughout the roller assembly lifecycle, thereby extending service life while sustaining reliable substrate control
Solution Approach 2:
The compressible material acts as a cushioning element that compensates for wear and dimensional changes in the washer assembly over time, maintaining consistent substrate grip and rotation control throughout the extended service life of the roller assembly
