Solar Cell Transport Traceability Through Frame Position Coding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing processes for solar cells face challenges in accurately tracing and recording process information at the solar cell level, leading to confusion and loss of information during transport and processing.
Innovation Solution
A method and device for tracing solar cells by coding each cell with a unique code based on the frame code of the loading frame, associating process information with these codes, and uploading them to a computer system for accurate record-keeping, using sensors to monitor and correct transfer abnormalities, and integrating with a computer system for comprehensive traceability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If solar cells are transported through multiple processes without individual coding, then the transport process is simple, but process information is lost and records become confused
Solution Approach 1:
The patent divides the loading frame into multiple positions and assigns unique cell codes to each solar cell based on its position. This segmentation allows individual tracking of each solar cell through the manufacturing process, preventing information loss and confusion while maintaining manageable complexity through systematic coding.
Solution Approach 2:
The patent implements coding of solar cells with unique identifiers before they enter the transport and processing sequence. By pre-assigning cell codes based on loading frame positions and caching them in advance, the system establishes traceability from the outset, enabling accurate record-keeping without adding complexity during the actual transport process.
2Reliability
If sensors are added to monitor transfer abnormalities, then tracing accuracy improves, but device complexity increases
Solution Approach 1:
The patent incorporates sensors that detect transfer abnormalities and provide feedback to the control system. When a solar cell is detected to be transferred abnormally, the system generates an alarm and can pause operation, ensuring tracing accuracy through continuous monitoring while maintaining reasonable complexity through targeted rather than universal sensing.
