摘要:
Backsheet (10, 20) for photovoltaic panels (100, 200) with conductive interface elements (130a-d) intended to simplify the electrical connection of the terminal points of the circuit to the back junction box (141 ); said conductive elements (130a-d) are of the non-through type through the backsheet, with double contacting face (131, 132), and are integrated on the front side (114, 214) towards the cells within recessed seats (111, 211) and in correspondence of through-holes (110, 210) in such a way as to enable an electrical connection by contact from the back side (115, 215) through said holes, in a guided way, by means of respective conductive elements protruding and fastened to the junction box. In particular, such a simplified contacting solution can be realized with extreme precision, without manual operations and at extremely low costs, with an automated assembly method.
摘要:
An assembly method (10) and a combined and bivalent workstation (S2) for automatically assembling photovoltaic panels, with printing of ECA on cell portions and progressive arrangement with a partial superimposition on the contacts, preforming shingled strings (402) in a continuous cycle, which are ready for loading on a backsheet, without dry-curing. The method (10) provides a macro-phase of lay-up (11) entirely made in said station (S2), with simultaneous and coordinated sub-phases (11.1 11.9): picking (11.1) of portions with a first handler (R1a - R1b) and control, oriented loading on a vacuum belt (11.2), control of positioning on the belt (11.3), printing of ECA (11.4), control of printing and positioning (11.5), progressive superimpositions (11.6) on a shuttle-tray (210) with bidirectional translation coordinated with a second handler (R2) with chocked vacuum, picking of the shingled string (11.7) with a third handler (R3), control of string alignment (11.8), loading and pre-fixing (11.9). Vision systems (V1, V2, V3) are integrated for the execution of said sub-phases.
摘要:
A method and related automatic production plant are disclosed for the silk-screen printing of inks or conductive pastes on photovoltaic cells or wafers, with an integrated handling system of the LSM moving coils drive type, wherein multiple shuttles with on-board coils act on a rail with permanent magnets in an independent but coordinated way, synchronous and/or asynchronous with respect to each other, to simultaneously perform missions different from each other in such a way as to advantageously carry out the printing operating steps provided by the method. Each shuttle is provided with an equipped tray of the removable type which is specifically configured to carry out the automated processing of the single cell, it also being intended to interact with the plant.
摘要:
Automatic production system (10) and production process (20a-b) for the automatic manufacturing of conductive backsheets (300) 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 (11 ) combined with a secondary line (12) having a flow converging to a station of calibrated superimposition with fixing (113). 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 (308) holed in correspondence of the electrical contacts comprising an automatic picking device (126) which takes, roto-translates and holds said multi-layer element during processing and releases it only after said calibrated superimposition with fixing. The system (10) is combined with a particular control system (140) made up of at least four devices (141-4) integrated with one another to enable calibration and check the automated processes.
摘要:
Plant (10) and system for the automatic horizontal assembly of photovoltaic panels (30) with front-back-contact solar cells (300-1) of crystalline silicon, of the type called H-type, the contacting being carried out at a temperature lower than 150°C also with the prefixing of conductive elements onto the encapsulating layer; the present invention solves the main problems of the conventional stringing systems and provides high production capacity with a precise positioning of the components. The plant (10) is made up of single workstations (100A-I) of the modular type which are arranged sequentially in a linear series, individually equipped according to the specific working process, being adjacent and laterally open to be crossed by the conveying line (110) of the trays (109) containing the panels being worked; after the automatic assembly in said plant (10), the panels are ready to be rolled in conventional furnaces.
