AUTOMATIC PRODUCTION SYSTEM AND PRODUCTION PROCESS OF A CONDUCTIVE BACKSHEET WITH INTEGRATED ENCAPSULATING AND DIELECTRIC LAYER FOR PHOTOVOLTAIC PANELS

摘要

Automatic production system and production process for the automatic manufacturing of conductive backsheets with an integrated encapsulating and dielectric layer, for photovoltaic panels of the back-contact type. The system includes operating stations in sequence and is made up of at least one main line combined with a secondary line having a flow converging to a station of calibrated superimposition with fixing. The main line, on trays on a continuous conveying system, arranges and prepares the back supporting and conductive layer, whereas the secondary line forms the encapsulating and dielectric multi-layer element holed in correspondence of the electrical contacts comprising an automatic picking device which takes, roto-translates and holds said multi-layer element during processing and releases it only after the calibrated superimposition with fixing. The system is combined with a control system made up of at least four devices integrated with one another to enable calibration and check the automated processes.

1. Automatic production system (10) for the assembly and control of conductive backsheets for photovoltaic panels with a back-contact architecture, said backsheets being of the type with an integrated encapsulating and dielectric layer, said system being characterised in that it comprises:
at least one processing main line; at least one processing secondary line; wherein said main line is combined with said secondary line, each line being made up of operating stations which are configured in sequence with a flow converging to a common station of calibrated superimposition and fixing to form said conductive, backsheet with an integrated encapsulating and dielectric layer; said main line forming on the lower part the supporting conductive backsheet, which is carried on trays on a continuous conveying system; said secondary line forming on the upper part the encapsulating and dielectric multi-layer element in such a way as to act as an insulating mask once superimposed and fixed on said conductive backsheet in said station of calibrated superimposition; said system comprising an integrated control system for controlling the positions and the processes by means of the comparison of the actual status with a predefined status, said integrated system being made up of at least four control devices which are individually placed in correspondence of the stations to be controlled and also automatically integrated with one another in such a way as to enable the processing or the simple passage of the product being processed to the following station; said secondary line comprising an automatic picking device which is continuous and permanent along the stations being intended to take, move and hold individually said encapsulating and dielectric multi-layer element during processing and release it only after the fixing on said conductive backsheet at said station of calibrated superimposition, in such a way as to combine and synchronize the two lines according to the detections by said integrated control system and compensating for the alignment and the relative positioning of said holed encapsulating and dielectric multi-layer element with respect to said conductive backsheet (304); said system ending in the unloading station of said conductive backsheet with an integrated encapsulating and dielectric layer from the tray with at least three branches of which one is for the continuous conveying of said tray and two are for the finished product, being respectively of the compliant and non-compliant type.
