Production device and production method of conductive interconnection board, and conductive interconnection board

Abstract

The invention provides a production device and a production method of a conductive interconnection board of a back contact battery and the conductive interconnection board, and relates to the technical field of solar photovoltaics. The device comprises a workbench used for bearing a substrate, a wiring unit used for arranging a conductive wire on the substrate, and a moving unit used for enablingthe wiring unit and the substrate to move relatively. The wiring unit comprises: a plurality of wire pipes which are arranged side by side; a first group of conveying mechanisms which are used for conveying a plurality of conductive wires into the wire tubes from the feeding positions from the inlets of the corresponding wire tubes; a cutting mechanism which is used for cutting off the conductivewire in the wire pipe to obtain a wire section; a heating and rolling mechanism which is used for rolling the wire section on a substrate to form a conductive interconnection board; and a second groupof conveying mechanisms which are used for respectively introducing the plurality of wire sections into the heating and rolling mechanism from the outlets of the corresponding wire pipes. The conductive interconnection board is low in production cost and high in production efficiency.

Description

technical field [0001] The invention relates to the field of solar photovoltaic technology, in particular to a production device, a production method, and a conductive interconnection plate of a back contact battery. Background technique [0002] In the production of back-contact solar cells, it is necessary to electrically interconnect each cell. [0003] At present, there are mainly two types of conductive interconnections for back-contact solar cells. One is to pattern the copper foil laminated with the substrate to obtain a conductive interconnection plate, and to realize the conductive interconnection through the conductive interconnection plate. Sheet welding, so as to realize the conductive interconnection of each battery sheet. [0004] The above-mentioned conductive interconnection technology of back-contact solar cells, the first one requires patterning of the copper foil laminated with the substrate, which requires the use of a large amount of copper foil, and th...
