Photovoltaic module recovery device and method based on EVA light passivation mechanism

Abstract

The invention discloses a photovoltaic module recycling device and method based on an EVA light passivation mechanism, the photovoltaic module recycling device comprises a feeding conveying line, a darkroom, a suction cup assembly and a discharging conveying chamber, the feeding conveying line comprises a pair of supports a and a roller shaft a and is used for conveying a frameless photovoltaic module to the darkroom, and the darkroom comprises an ultraviolet lamp; carrying out ultraviolet irradiation on the frameless photovoltaic module to change the EVA three-dimensional network of the frameless photovoltaic module, and rapidly oxidizing and delaminating; the suction cup assembly comprises a supporting frame, a guide rail, a swing supporting arm and a vacuum suction cup. The frameless photovoltaic assembly is disassembled through cooperation of the vacuum suction cup and the swing supporting arm. The discharging conveying line comprises a pair of supports b and a rolling shaft b, and the split frameless photovoltaic modules are conveyed to the next procedure. According to the invention, ultraviolet irradiation is carried out on the frameless photovoltaic module at normal temperature, so that the packaging material of the frameless photovoltaic module, namely the three-dimensional net shape of EVA, is changed, the packaging material is quickly oxidized and delaminated, gaps are formed among the materials, and external force does not need to be applied when the materials are separated.

Description

technical field [0001] The invention belongs to the technical field of resource recovery automation, in particular to a photovoltaic module recovery device based on the EVA light passivation mechanism, and also relates to a photovoltaic module recovery method based on the EVA light passivation mechanism. Background technique [0002] In the past ten years, my country's photovoltaic installed capacity and cumulative installed capacity have ranked first in the world. According to a survey supported by the Photovoltaic Committee of the China Renewable Energy Society, there are photovoltaic panels in the southwest and northwest regions of my country that have been generating electricity for more than 30 years. The large-scale installation of photovoltaic modules in China began in 2009. Through the "Golden Sun Demonstration Project" supported by the state, the industrialization and large-scale development of domestic photovoltaic power generation have been rapidly promoted. [0...
