Abstract

The invention discloses a multi-layer welding strip and a battery piece conveying device. The device comprises a split synchronous belt conveyor line, a battery piece conveying part, a floating positioning station, a welding strip gripping and clamping part, a welding strip sucking and releasing part and a series welding battery string transmission line. According to the invention, a photovoltaic battery module can be easily produced by the cooperation between the parts; the solar battery pieces in the photovoltaic battery module are welded in a staggered mode, which can simplify the production technical process and improve the production efficiency as compared with the traditional series welding process of a battery string welded by single battery pieces in series. In addition, the output voltage and output current of the photovoltaic battery module can be improved at the same time, and the output power is then improved. The photovoltaic battery sub modules with an imbricate structure are compact in structure and reasonable in layout.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a multi-layer soldering strip and cell sheet handling device. Background technique [0002] The production process of monocrystalline silicon and polycrystalline silicon solar cells involves the string welding process of solar cells. The existing automatic solar cell welding machine adopts the back-connected welding method of adjacent cells to complete the string welding process of a single string of cells step by step. , that is, the cell adsorption and handling device first places the 156mm×156mm cell on the transmission line of the serially welded cell string, and then the ribbon clamping part extracts a plurality of interconnected ribbons whose length is about twice the side length of the cell from the wire-releasing mechanism and puts them together. It is cut by the ribbon cutting module, and then the ribbon clamping part will directly place the cut multiple ribbons on...
