Abstract

The invention discloses a welding device and series welding equipment. The welding device comprises a rack, a mounting plate mounted on the rack, and a heating component for heating the mounting plate. The welding device further comprises a pressing needle for pressing a portion to be welded, and the pressing needle is mounted on the mounting plate and can acquire heat from the mounting plate. Thepressing needle carries out heating welding on stacked battery pieces and welding strips through the acquired heat. According to the technical scheme, the welding temperature can be accurately controlled through pressing needle welding, and therefore the welding effect of the front faces and the back faces of the battery pieces can be effectively controlled, and the welding quality of a battery string can be improved.

Description

technical field [0001] The invention belongs to the field of photovoltaic cell production, and in particular relates to a welding device and series welding equipment. Background technique [0002] In the production process of photovoltaic cells, there is a process of welding battery sheets into battery strings. The traditional process is to use infrared lamps for heating and welding, and control the welding effect of the welding light box on the battery strings placed below by controlling the power of the infrared lamps. [0003] However, the light box is not airtight, and the heat is dissipated relatively quickly, so it is difficult to accurately control the welding temperature. Moreover, it is difficult to guarantee the welding effect of the welding ribbon on the back of the cell. Contents of the invention [0004] In view of this, the present invention aims to provide a welding device and stringing equipment to solve the problem of poor welding effect of the backside ...
