Solar Panel Frame Removal Machine for Efficient PV Recycling

A photovoltaic module aluminium frame removal machine is a piece of equipment specifically designed for the pre-treatment of end-of-life solar panels. It rapidly separates the external aluminium frame from the module, thereby improving the efficiency of subsequent recovery of glass, silicon, and metal, whilst reducing labour costs and the risks associated with module dismantling.

Why Are Aluminium Frames Removed First in PV Module Recycling?

In a standard crystalline silicon PV module, the aluminium frame typically accounts for 8–12 per cent of the module’s total weight. Not only does it possess significant recycling value, but it also affects the stable operation of subsequent crushing, pyrolysis and sorting processes. Furthermore, if the modules proceed directly to further processing, the aluminium frames can easily cause blockages in conveyor equipment, increased wear on cutting tools and a reduction in sorting accuracy.

Traditional manual frame removal methods rely primarily on pneumatic tools or manual labour, with a single worker typically able to process only a few dozen modules per day. Faced with the future market for large-scale decommissioned photovoltaic modules, manual methods are unlikely to meet the demands of industrial-scale recycling in terms of both efficiency and cost.

Working Principle and Features of the Solar Panel Aluminium Frame Removal Machine

The solar panel aluminium frame removal machine employs a semi-automatic dismantling method. It secures the module in place using a positioning and clamping mechanism, and utilises a specialised separation mechanism to rapidly peel and separate the aluminium frame from the glass module. The entire process does not require the modules to be crushed, thereby maximising the integrity of the materials for subsequent recycling.

Compared with traditional manual dismantling, this equipment offers the following features:

Rapid aluminium frame removal, suitable for continuous batch processing;

Reduced manual involvement, lowering labour intensity and safety risks;

Separate collection of aluminium frames, enhancing the recycling value of the aluminium;

Preservation of the module’s main body, facilitating subsequent glass separation, junction box removal and pyrolysis recycling;

Key pre-treatment equipment in photovoltaic recycling production lines

From the perspective of recycling economics, efficient front-end pre-treatment not only enhances the purity of the recovered materials but also reduces energy consumption and equipment wear costs. Furthermore, within a complete solar panel recycling process, aluminium frame removal machines are typically used in combination with junction box removal equipment, glass separation systems, pyrolysis equipment and metal sorting systems to form a continuous processing workflow.
