Embodiment 1

[0057] Such as figure 1 and figure 2 As shown, the equipment of the present invention includes a laser scanning device, a first collecting and conveying device, a hot knife device, a low-temperature processing device 1, a second collecting and conveying device, a rolling device 17 and a separating device. The solar cell assembly 28 includes a back plate 281, a lower EVA film 282, a cell sheet 283, an upper cover EVA film 284 and a five-layer structure of glass 285, wherein the cell sheet 283 includes an aluminum back field coating, a metal bus strip, a metal solder belt and cell body.

[0058] A feeding device can also be arranged in front of the laser scanning device as required. On the feeding device, the laser scanning device, the first collecting and conveying device, the low-temperature processing device 1, the second collecting and conveying device, and the rolling device 17, a transfer platform for transferring the solar cell module 28 to the next device is provided,...

Embodiment 2

[0069] The method for dismantling solar cell assembly of the present invention comprises the steps:

[0070] a. Prepare the equipment for dismantling solar cell modules described in Embodiment 1, and place the glass 285 of the solar cell module 28 facing upward on the delivery platform of the feeding device. At this time, the delivery platform of the feeding device and the first laser scanning device A delivery platform 2 starts the delivery, and sends the solar battery module 28 into the laser scanning device, and the delivery platform of the feeding device and the first delivery platform 2 stop running.

[0071] b. The swing controller 6 of the laser scanning device drives the laser head 5 to swing vertically to the feeding direction of the solar cell assembly 28. After the laser head 5 scans the linear area in the width direction of the solar cell assembly 28, the first delivery platform 2 drives the solar cell The assembly 28 moves towards the direction of the vacuum chuck...

Abstract

The invention provides equipment and a method for disassembling a solar cell module. The equipment for disassembling the solar cell module comprises a laser scanning device, a first collecting and conveying device, a hot knife device, a low-temperature processing device, a second collecting and conveying device, a rolling device and a separating device. According to the equipment and the method for disassembling the solar cell module provided by the invention, glass and an upper cover ethyl vinyl acetate (EVA) film adhered to the glass are disassembled from the solar cell module through the laser scanning device, and the glass and the upper cover EVA film adhered to the glass are separated through the hot knife device, so that the complete glass is obtained. Then through a low-temperatureenvironment manufactured by a low-temperature processing device under normal pressure, a complete backboard, a complete laid EVA film and a cell of the solar cell module are obtained. According to theequipment and the method for disassembling the solar cell module provided by the invention, the cells are crushed through the rolling device so as to obtain silicon wafer particles, metal welding strips and metal busbar, and different materials are separated and sorted through the separating device, so that the environment-friendly disassembling and the classified recycling of waste solar cell modules are achieved.

Description

technical field [0001] The invention relates to the field of solar battery recycling, in particular to a device and method for dismantling solar battery components. Background technique [0002] The photovoltaic power generation market is developing rapidly, which requires the post-life photovoltaic modules, especially crystalline silicon battery modules and their components (glass, silicon, copper, aluminum, silver, plastic, etc.) Harmless 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 equipment" regulations, and listed p...
