Adjustable Base Frame for Substrate Carrier Roller Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing process of display panels faces issues with substrate fragmentation due to impact or crooked flow when substrates transition from conveyer belts to rollers, leading to yield reduction and waste.
Innovation Solution
A base frame for a substrate carrier is designed with a first and second vertical rod, cross rods, and extensions that accommodate rollers, allowing for adjustable spacing to prevent substrate impact and fragmentation, and a substrate transfer mechanism with additional rollers to ensure smooth substrate flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spacing between conveyer belt and rollers is reduced to prevent substrate impact, then substrate fragmentation is prevented, but the device complexity increases due to additional rollers and adjustable base frame structure
Solution Approach 1:
The base frame incorporates adjustable components that allow the spacing between the conveyer belt and rollers to be dynamically modified. This enables the system to adapt to different substrate sizes and conveyance requirements while maintaining proper support geometry to prevent fragmentation.
Solution Approach 2:
The base frame is divided into multiple adjustable segments including vertical rod extensions and positioning mechanisms. This segmentation allows independent adjustment of roller positions to optimize the transition zone between conveyer belt and rollers, preventing substrate impact without requiring complete structural redesign.
2Productivity
If additional rollers are added to narrow the spacing and ensure smooth substrate flow, then substrate yield increases, but the manufacturing cost and device complexity increase
Solution Approach 1:
The additional rollers are integrated into a multi-functional base frame structure that serves both as a support framework and a conveyance mechanism. The same structural components provide both mechanical support and controlled substrate guidance, reducing the need for separate dedicated elements.
Solution Approach 2:
The base frame acts as an intermediary structure that mediates the transition between the conveyer belt and the carrier platform. By providing a structured framework with integrated rollers, it creates a gradual transition zone that protects substrates from impact while maintaining production efficiency.
3Adaptability or versatility
If the base frame structure is made adjustable to accommodate different storage modes, then adaptability increases, but the manufacturing precision requirements increase
Solution Approach 1:
The base frame employs adjustable parameters such as rod extension lengths and roller positioning that can be modified to accommodate different storage configurations. These parameter changes allow the same structure to adapt to various substrate sizes and carrier types without requiring multiple dedicated fixtures.
Solution Approach 2:
The adjustable components are pre-configured with standard positioning features and connection mechanisms that facilitate repeatable setup. This preliminary preparation of adjustment mechanisms reduces the precision requirements during actual operation, as the systems are designed to accommodate reasonable tolerances through their inherent adjustment capabilities.
