Particularly, along with the separation on the sticky tape is rolled up from the sticky tape, the sticky tape is under adsorption of adsorption apparatus, along with adsorption apparatus motion to the station that photovoltaic module is located, adsorption apparatus can be coaxial with first pin hole and second pin hole alignment, pastes the sticky tape on photovoltaic module's backplate, realizes the protection to the photovoltaic module surface.
And S106, performing laminating operation on the photovoltaic module.
Particularly, after the tape-stripping is accomplished, can use the laminator to begin to laminate to photovoltaic module, when the laminator applys pressure, the glue that overflows between each layer can flow through first pin hole and second pin hole, because the isolation of sticky tape, the glue that overflows can remain on the sticky tape surface, and can not directly solidify and bond on the photovoltaic module surface to, can not damage photovoltaic module's surface quality.
And S107, after the lamination is finished, removing the adhesive tape adhered to the back plate of the photovoltaic module.
Specifically, after each layer of structure in the photovoltaic module is firmly bonded and fixed, the laminator can remove the pressure, tear off the adhesive tape adhered to the back plate of the photovoltaic module after the lamination is finished, and take away the residual glue on the adhesive tape along with the removal of the adhesive tape, so that it can be understood that the residual overflowed glue on the back plate of the photovoltaic module is also removed.
In the embodiment of the invention, the method is used for improving the laminating process in the laminating process, the equipment is used for supplementing the processes of bonding and removing the adhesive tape in the traditional laminating process, the automatic unfolding and conveying of the adhesive tape can be realized, and the automatic bonding of the adhesive tape can be completed by using the adsorption mechanism, so that the manual one-by-one adhesive tape sticking is avoided, and compared with the participation of manpower in the traditional laminating process, the labor input can be reduced, the labor cost is reduced, and the laminating efficiency and the product quality are improved. In addition, the application of auxiliary components such as photoelectric sensors and cutting mechanisms can further improve the automation degree of the equipment, greatly weaken the human participation degree, liberate the labor force of people and improve the laminating efficiency.
