Nanjing Kaiyan Electronics has applied for a patent for a photovoltaic module resource recycling system and recovery method aimed at enhancing frame dismantling efficiency and ensuring effective frame removal. The patent application, co-filed with Nanjing Normal University, is identified under publication number CN119839008A with an application date of January 2025.
The patent abstract indicates that the invention pertains to the recycling technology of photovoltaic modules, which include components such as frames, glass, solar cells, and back panels. The system involves the reutilization of broken frames, glass powder recycling, sorting and reuse of solar cells, and back panel recycling. The pre-treatment process for recycling photovoltaic modules includes the recovery of components and multi-layer segmentation of the modules.
The recovery component securely fixes the photovoltaic module and employs a cutting blade alongside a rotating arc plate to detach the frame. This process significantly enhances the efficiency of frame removal while ensuring that the frame’s dismantling is executed effectively. The multi-layer segmentation component is equipped with two sets of rotatable cutting blades designed to separate the glass, solar cells, and back panels for subsequent recycling. Additionally, one side of the multi-layer segmentation component features a fixing component that ensures the photovoltaic module remains stationary during the cutting process, guaranteeing precise segmentation.
