Solar Panel Bond-Line Cutting for Clean Glass Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for dismantling and disposing of solar panels are inefficient, particularly in disassembling and disposing of solar panels, and the solar panels are inefficient in terms of resource utilization and energy saving, especially when both glass plates on both surfaces need to be disassembled.
Innovation Solution
A solar panel disassembling apparatus using a wire-shaped cutting blade and a fixing structure that holds both surfaces of the solar panel, allowing for precise separation of glass plates from the film layer by cutting the bonding surface without crushing, utilizing a first and second fixing plate, a moving unit, and a wire-shaped cutting blade to separate the glass plates from the film layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a scraper or blade is used to remove the film layer from the glass plate, then the disassembly process can be initiated, but the film layer cannot be cleanly removed and damage occurs to the components
Solution Approach 1:
The cutting blade is divided into multiple segments (first cutting blade and second cutting blade) that can independently cut the bonding surface at different locations. This segmentation allows precise cutting at specific bond lines while avoiding damage to the film layer, achieving clean separation without the need for aggressive scraping methods
Solution Approach 2:
The fixing structure acts as an intermediary mechanism that holds the solar panel in a controlled state during cutting. By securing the panel between fixing plates and applying clamping force, the system enables precise cutting blade interaction with the bonding surface while preventing uncontrolled movement that would cause damage
2Manufacturing precision
If both glass plates in a double-sided solar panel are to be disassembled, then complete separation can be achieved, but the complexity and time required increase significantly
Solution Approach 1:
The first cutting blade and second cutting blade are configured to simultaneously cut the bonding surfaces of both glass plates in a single operational sequence. The fixing structure holds both glass plates in place at the same time, allowing parallel cutting operations that reduce total disassembly time while maintaining complete separation
Solution Approach 2:
The cutting blades continuously move along the bonding surfaces of both glass plates without interruption, maintaining constant cutting action throughout the disassembly process. This continuous operation eliminates idle time between cutting operations and ensures complete separation of both glass plates from the film layer
3Strength
If the glass plate is bonded to the film layer with strong bonding, then the solar panel maintains structural integrity, but the film layer becomes difficult to remove without crushing the glass plate
Solution Approach 1:
The fixing structure is positioned and adjusted in advance to securely hold the solar panel before cutting begins. The clamping force is applied preliminarily to stabilize the panel, ensuring that when the cutting blades engage the bonding surface, the glass plate remains in the correct position and does not shift or crack during the separation process

AI summary
There is provided a solar panel disassembling apparatus. The solar panel disassembling apparatus includes: a first fixing plate and a second fixing plate that hold both surfaces of the solar panel, respectively, in a state of having a distance from each other without coming into close contact with each other such that bond lines at a perimeter of the bonding surface are exposed: a moving unit that moves the first fixing plate and the second fixing plate in a parallel direction parallel to the bonding surface; and a wire-shaped cutting blade that is disposed in front of the solar panel in a movement direction of the solar panel to be parallel to the bonding surface and cuts the bonding surface, while passing through the bond line exposed toward the front between the first fixing plate and the second fixing plate.
