Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in efficiently disassembling solar panels into a glass plate and a film-type stack after the exterior frame is removed, as existing methods often damage the glass plate and fail to cleanly separate the film stack, leading to management issues for large-scale solar photovoltaic power generation facilities.
Innovation Solution
A solar panel disassembling apparatus comprising a supporting plate, a moving scraper module with a blade, and a moving pressing module that uses heat and precise alignment to separate the glass plate from the film stack, allowing for accurate cutting and disassembly without damaging the glass plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a solar panel is disassembled using conventional methods, then the disassembly process is simple, but the glass plate is damaged and the film stack is not cleanly separated
Solution Approach 1:
The disassembling apparatus is divided into multiple functional modules: a pressing module that applies pressure to the film stack, a heating module that heats the film stack, and a scraping module with a blade that scrapes the film stack from the glass plate. Each module performs a specific function, allowing precise control over the disassembly process while maintaining manageable complexity through modular design.
Solution Approach 2:
Before the scraping operation, the pressing module pre-presses the film stack to align it, and the heating module pre-heats the film stack to reduce its adhesion to the glass plate. These preliminary actions prepare the film stack for clean separation, ensuring precise disassembly without damaging the glass plate.
2Reliability
If the film stack is not properly aligned before scraping, then the disassembly process is faster, but the glass plate is damaged
Solution Approach 1:
The pressing module performs preliminary pressing of the film stack to align it properly before the scraping operation begins. This pre-alignment ensures that the blade can scrape the film stack cleanly without causing damage to the glass plate, maintaining reliability while minimizing time loss through efficient sequential operations.
3Manufacturing precision
If the blade is not precisely positioned, then the apparatus is easier to operate, but the film stack is not cleanly separated from the glass plate
Solution Approach 1:
The apparatus includes a load cell that detects the contact force between the blade and the film stack in real-time. The controller receives feedback from the load cell and automatically adjusts the blade position to maintain optimal contact force, ensuring precise film stack separation without requiring manual adjustment or complex operation by the user.
4Manufacturing precision
If the film stack is heated to reduce adhesion, then the separation is cleaner, but the energy consumption increases
Solution Approach 1:
The heating module changes the temperature parameter of the film stack to reduce its adhesion to the glass plate. By controlling the temperature parameter, the apparatus achieves cleaner separation while managing energy consumption through targeted heating of only the film stack area that needs to be separated.
