Title:
SOLAR CELL WELDING MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/155327
Kind Code:
A1
Abstract:
A solar cell welding machine (100) comprises a machine base, a conveying assembly (1), a first welding-strip feeding device (3), a second welding-strip feeding device (4), and a cell-member loading and unloading device (5), an interconnection welding device (6), and a busbar welding device (7). The machine base has a cell-member laying station (11), a waiting station (12), an interconnection welding station (14), and a busbar welding station (15). The conveying assembly enables a plurality of solar cell members (b) to successively pass through the cell-member laying station to be delivered to the interconnection welding station. The first welding-strip feeding device conveys a first welding strip (c) to the cell-member laying station. The second welding-strip feeding device conveys a plurality of second welding strips (d) to the waiting station and the cell-member laying station. The cell-member loading and unloading device conveys a solar cell-member to the cell-member laying station. The interconnection welding device forms a plurality of interconnected solar cell strings (a) by means of welding. The busbar welding device forms a cell interconnection plate (A) by means of welding. The solar cell welding machine improves production efficiency, simplifies sorting and busbar welding operations and processes related to solar cell strings, enables solar cell members to be compactly arranged, and improves the overall conversion efficiency of photovoltaic modules.
