Automated dismantling and separation system for solar panels

An automated dismantling and separation system for solar panels is provided, which mainly disassembles the aluminum frame of the solar panel to form the stack material through the frame disassembly system, and the stack material is transported by the handling device to the stack material disassembly system, and the stack material is heated through the heating unit to melt the EVA adhesive between the glass upper cover, wafer layer and backplane layer. Then the topmost material is removed through the suckers of the handling device to expose the residual adhesive, and the residual adhesive is scraped off by the scraper, so that each layer of material is repeatedly removed in sequence and collected and recycled respectively to achieve the purpose of high efficiency and environmental protection.

Delamination of used solar module

Delamination of a solar module (for, e.g., purposes of recycling) may be achieved by applying a rotating member(s) against surface(s) of a used solar module. In certain embodiments, the rotating member may comprise a straight router bit, which may be applied under computer control. Successive application of rotating member(s) at different heights, may afford the collection of different materials. According to one particular embodiment, a rotating router bit may be applied first against a polymer backsheet, and then at a different height against other materials comprising metals and PV material such as crystalline silicon. Collection of resulting fractions produced by delamination at different heights, can produce material (e.g., metals, silicon) of relatively high purity and suitable for reuse.
