Abstract

The invention discloses a welding pressing device and a series welding machine. The welding pressing device comprises a pressing frame, a cooling structure and a pressing against structure. The cooling structure is mounted on the pressing frame and corresponds to the battery piece welding strip flattening area, a cooling pipeline is arranged in the cooling structure, and cooling media circulate inthe cooling pipeline. The pressing against structure is arranged on the cooling structure. The series welding machine comprises the welding pressing device, a battery piece feeding device, a weldingstrip feeding device, a welding conveying device, a welding lamp box and a moving device, the battery piece feeding device provides a battery piece, the welding strip feeding device provides a weldingstrip, the battery piece feeding device and the welding strip feeding device arrange the welding strip and the battery piece on the welding conveying device, the moving device drives the welding lampbox to lift, the welding pressing device presses the object to be welded, and the welding lamp box welds the object to be welded. The welding strip tin immersion phenomenon of the battery piece welding strip flattening area is reduced, and the shredding problem in the battery piece combing production can be solved.

Description

technical field [0001] The invention belongs to the field of photovoltaic cell production, and in particular relates to a welding pressing device and a stringer using the welding pressing device. Background technique [0002] In the field of photovoltaic production, in order to improve the photoelectric conversion rate per unit area of ​​photovoltaic modules, a parallel photovoltaic module is currently proposed, that is, the middle section of the welding ribbon is flattened, and the welding ribbon is used to connect two overlapping cells at the edges. The flattened middle section is located in the overlapping area of ​​the two battery sheets. [0003] When the ribbon is welded to the cell, the ribbon segment at the flattened area of ​​the ribbon will usually be tinned due to the heat during welding, resulting in thickening of the overlapping area, thereby increasing the split rate of the subsequent process. Contents of the invention [0004] A main purpose of the present ...
