Abstract

The invention relates to the technical field of welding, in particular to a pressing needle device and welding equipment. The pressing needle device comprises a pressing needle assembly. The pressingneedle assembly comprises a connecting beam, fixing beams and pressing needles. The fixing beams are connected with the connecting beam in an intersecting manner, and the pressing needles are mountedon the fixing beams. By means of the technical scheme, the welding effect can be improved, and the assembly efficiency of the pressing needles can be improved.

Description

technical field [0001] The present application relates to the field of welding technology, in particular, to a needle pressing device and welding equipment. Background technique [0002] Solar photovoltaic cells, referred to as photovoltaic cells for short, use the photovoltaic effect to directly convert the sun's light energy into electrical energy. The photovoltaic effect, also known as the "photovoltaic effect", refers to the phenomenon that light causes a potential difference between different parts of an inhomogeneous semiconductor or a combination of a semiconductor and a metal. When sunlight irradiates the photovoltaic cell, the photons of sunlight excite electron-hole pairs in the cell, and the electrons and holes move to the two ends of the cell respectively. If the external path is formed, a current will be formed to generate electrical energy. The power generation efficiency of photovoltaic cells mainly depends on the amount of light energy received by the solar ...
