The middle layer of the back plate mainly provides mechanical property, electrical insulation property and barrier property, and the middle layer is commonly used as a PET polyester material, so that the PET polyester material has poor ultraviolet light resistance and humid heat aging resistance, and more modified high-barrier hydrolysis-resistant PET is obtained. The inner layer of the backboard mainly ensures reliable adhesion of the backboard and the component packaging material.

The pasting of general solar energy encapsulation backplate is through the manual rubber coating, and the manual rubber coating can only be carried out the rubber coating to encapsulation backplate according to operating personnel's experience to the manual rubber coating, and operating efficiency is comparatively low, and this application aims at intelligent the encapsulation backplate and carries out the rubber coating drying, and semi-automatization is spacing and is carrying out the accuse to encapsulation backplate rubber coating volume to the rubber coating position, realizes that the accurate fixed rubber coating is carried out to encapsulation backplate, is dry.
