System for realising connection lines between strings of cells in photovoltaic modules

摘要

The invention relates to a system for realising connection lines between strings of cells in photovoltaic modules. Such lines consists of conductor foils L welded to electric terminals T of the strings S. The system 1 comprises: - a support platform 2 for at least one photovoltaic module having the electric terminals bare: - at least one device 10 for positioning at least one foil L at one or more terminals, the positioning device comprising one or more releasable gripping elements 11 of the foil L; - at least one device 20 for welding the foil L to one or more electric terminals. The system being characterised by the fact that the positioning device comprises at least one screening plate for welding 12 positioned near the gripping elements. The plate and the gripping elements being movable in relation to each other between a first position, in which they are distanced from each other to create an aperture 13 for the insertion of the terminals, and a second position, in which they are brought closer together so as to reduce the opening of such aperture and allow contact of the foil (L) with one or more electric terminals T.
