Abstract

The invention relates to an overlapping type string welder. The overlapping type string welder comprises a feeding device, a detecting device, a transportation adjusting device, a solder feeding device, an overlapping device and a welding device, wherein the feeding device, the detecting device, the transportation adjusting device, the solder feeding device, the overlapping device and the welding device are arranged along a conveying line; the solder feeding device is used for adding a conductive solder at one end of each cell; the overlapping device is used for overlapping the cells which are processed by the solder feeding device; the overlapping region of adjacent cells is capable of covering the conductive solder; the welding device is used for heating the conductive solder to form cell strings. The overlapping type string welder is capable of realizing an overall production process including welding and discharging of a single cell and tandem cell strings, is relatively high in production efficiency and is capable of satisfying the requirements of large-scale production.

Description

technical field [0001] The invention relates to a laminated string welding machine, which belongs to the field of photovoltaic equipment. Background technique [0002] With the increasing rise of photovoltaic module products, it has brought about the rapid development of my country's solar energy industry. With the continuous and rapid development of my country's manufacturing industry, great breakthroughs and improvements have been made in photovoltaic module packaging, silicon wafer processing, and crystalline silicon solar cell manufacturing. [0003] The stringer is one of the core equipment in the production process of traditional photovoltaic modules. It is a device that connects individual cells into battery strings through interconnecting bars. This traditional connection method will leave gaps between cells. At the same time, the part blocked by the interconnection strips cannot receive sunlight, which leads to a low area utilization rate of the entire traditional ...
