AI Technical Summary

⚠Technical Problem

In existing technologies, the separation of double-glass modules mainly relies on chemical reagents to dissolve the encapsulating film. This process is time-consuming and difficult to handle in the subsequent chemical reagent treatment. Furthermore, the module is prone to breakage during the drilling process, which affects the purity of subsequent material sorting.

⚗Method used

A double-glass module layer separation device is used. After the adhesive film is fixed by vacuum adsorption and softened by heating, it is separated into layers by wire cutting and metal brush or scraper, avoiding the use of chemical reagents.

🎯Benefits of technology

It achieves component layering without breakage, maintains component integrity, avoids chemical contamination, and improves separation efficiency and material purity.

Abstract

This invention relates to a layer separation device and process for double-glass modules, belonging to the technical field of photovoltaic module recycling equipment and processes. It includes a separation platform providing a work surface for the double-glass modules and equipped with a vacuum adsorption port; a module identification and alignment component disposed on the separation platform; a layer separation component configured to separate the double-glass modules, with a drive mechanism within the separation platform connecting the layer separation component to the drive mechanism; a glass gripping and transfer component; and a separation process. This invention can complete the layer separation of various materials such as the cover glass, silicon cell layer, and backsheet glass of a double-glass module, preventing breakage during the layer separation process and maintaining module integrity; it uses a physical method to separate the inner battery adhesive layer of the glass, avoiding secondary pollution caused by the use of chemical reagents.
