  The present invention relates to a recycling apparatus for a solar cell module.

  In order to reuse the constituent materials of the used solar cell module (glass substrate, sealing agent, solar cell, wiring material, back sheet, etc.), it is necessary to separate the respective materials from each other. A recycling apparatus is used to separate other materials including solar cells from the glass substrate.

  As a conventional recycling apparatus, the sealing agent described in Patent Document 1 is heated and softened, and the heated blade is placed between the glass substrate and other materials cracked by the grinding process together with the solar cell. There was something that made it touch and separate.

  However, Patent Document 1 does not describe in detail the transport mechanism of the module and the operation of the blade even in FIG. 6 and the like attached. For this reason, the mechanism for positively abutting and separating the blade between the glass substrate and the other material is unclear, and there is room for improvement.

  Therefore, in Patent Documents 2 and 3 filed by the inventor of the present application, the warping of the solar cell module is also followed, the blade is brought into contact with other materials without breaking the glass substrate, and it takes a short time. There has been proposed a recycling apparatus of a solar cell module which can be peeled off efficiently.
