Embodiment Construction

[0039] like Figure 1~3 As shown, the device for separating solar cell module glass provided by the present invention includes a transmission mechanism, a scraping mechanism, a laser scanning mechanism 5, a control mechanism, a clamping mechanism 7, a boosting mechanism, a blowing mechanism and a receiving mechanism.

[0040] The transmission mechanism is connected with the control mechanism, and it is used to drive the solar cell assembly to move under the control of the control mechanism. like Figure 4 As shown, the solar cell assembly includes an upper layer of glass 1 and a lower layer assembly 2 connected to the glass 1 through an adhesive film. The solar cell assembly is preferably a crystalline silicon solar cell assembly. In this embodiment, the lower layer assembly 2 includes silicon wafers from top to bottom. , film and back sheet; the conventional size of solar cell modules is 1 meter * 2 meters.

[0041] The transmission mechanism specifically includes a transmi...

Abstract

The invention provides a method for separating solar cell module glass. The method comprises the following steps that firstly, a scraper blade is preheated, and then a solar cell module is driven by atransmission mechanism to move forwards by a set distance; a blade of the scraper is cut into the solar cell module from the lower part of the solar cell module in an obliquely upward manner, and theblade of the scraper contacts with the lower surface of the glass; and then the solar cell module continues to move, and the adhesive film adhered to the glass and the lower-layer module bonded withthe adhesive film are scraped off together by the blade of the scraper. Before scraping, the solar cell module can be scanned by the laser scanning mechanism so as to reduce the adhesive force of theadhesive film on the lower surface of the glass. According to the invention, efficient separation of complete glass in a solar cell module, especially a crystalline silicon module, can be realized, and the residual glue rate of the glass surface is very low.

Description

technical field [0001] The invention relates to the field of solar cell recycling, in particular to a method for separating solar cell module glass. Background technique [0002] The photovoltaic power generation market is developing rapidly, which requires that photovoltaic modules after their lifespan, especially crystalline silicon battery modules and components (silicon, copper, aluminum, silver, glass, plastic, etc.) occupy more than 80% of the world market Harmful treatment, and even recycling, can alleviate the shortage of raw materials for photovoltaic devices, and reduce resource waste and ecological environment pollution. [0003] Internationally, the European and Japanese energy industries have carried out in-depth research on photovoltaic module recycling and harmless treatment technology and management systems, and have incorporated them into regulations and policies. In 2012, the European Union meeting formally changed the "waste electrical and electronic equi...
