Solar Panel Disassembly Using Wire Blade Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for disassembling solar panels, particularly double-sided panels, struggle to cleanly separate the glass plates from the film layer without crushing the glass, which complicates resource utilization and recycling processes.
Innovation Solution
A solar panel disassembling apparatus that uses a wire-shaped cutting blade to separate the glass plate and the film layer, with a supply module that fixes and moves the solar panel to expose the bond line and prevent perpendicular loading on the bonding surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a scraper or conventional disassembling method is used to separate the film layer from the glass plate, then the disassembling process can be performed, but the film layer cannot be cleanly removed and the glass plate may be crushed
Solution Approach 1:
The patent replaces the conventional scraper-based mechanical disassembling method with a wire-shaped cutting blade that uses a cutting mechanism. This substitution enables clean separation of the film layer from the glass plate without crushing the glass, as the wire blade precisely cuts through the bonding interface rather than scraping against it.
Solution Approach 2:
The patent changes the disassembling mechanism from scraping to cutting by introducing a wire-shaped blade with specific geometric parameters. The wire blade's thin profile and sharp edge allow it to penetrate the bonding layer and separate the film from the glass cleanly, transforming the disassembling process from a forceful scraping action to a precise cutting action.
2Device complexity
If the solar panel is disassembled with loads applied perpendicularly to the bonding surface, then the disassembling process is simpler, but the cut surfaces re-bond and the separation fails
Solution Approach 1:
The patent applies preliminary action by positioning the wire-shaped cutting blade to cut through the bonding layer before any perpendicular loading occurs. The blade is inserted and advanced to sever the bonding between film and glass, creating separated cut surfaces that prevent re-bonding even when subsequent loading is applied during the disassembling process.
Solution Approach 2:
The patent segments the solar panel structure by cutting through the bonding layer, separating the film layer from the glass plate into distinct segments. This segmentation prevents the cut surfaces from re-bonding by creating physical separation, allowing the disassembling process to proceed reliably even with perpendicular loads applied.
3Adaptability or versatility
If a double-sided solar panel is disassembled, then both glass plates must be separated from the film layer, but conventional methods cannot handle both surfaces effectively
Solution Approach 1:
The patent achieves universality by designing a wire-shaped cutting blade system that can effectively disassemble both single-sided and double-sided solar panels using the same cutting mechanism. The blade's ability to precisely cut through bonding layers on either surface of the film allows it to handle various panel configurations without requiring different disassembling methods.
Solution Approach 2:
The patent employs periodic action by sequentially processing each surface of the double-sided solar panel. The wire blade first cuts one surface, then the panel is repositioned and the blade cuts the other surface, creating a rhythmic periodic disassembling process that efficiently handles both sides without compromising productivity.

AI summary
A solar panel disassembling apparatus according to an embodiment of the present disclosure separates a glass plate of a solar panel and a film layer bonded to the glass plate from each other. The solar panel disassembling apparatus includes a supply module that stands and fixes the solar panel such that a bond line between the glass plate and the film layer is exposed upward and downward and that moves the solar panel in a parallel direction parallel to a bonding surface between the glass plate and the film layer, and a wire-shaped cutting blade that is disposed in front of the solar panel in a movement direction of the solar panel to have a distance from the supply module, is disposed in parallel to the bonding surface, and separates the glass plate and the film layer from each other.
