Abstract

The invention provides a multi-main-grid photovoltaic battery sheet and solder strip positioning device, which comprises a front end pulling positioning device and a tail positioning device, wherein the front end pulling positioning device comprises a first power mechanism, a sliding mechanism and a clamping jaw installed on the sliding mechanism, the first power mechanism drives the sliding mechanism to slide so as to make the clamping jaw clamping the front end of a solder strip pull the solder strip by a preset distance or make the clamping jaw after the solder strip releasing be completelyseparated from the solder strip, the tail positioning device comprises a second power mechanism, a guide plate provided with a plurality of guide grooves, a plurality of guide blocks and a pluralityof clamping blocks, each guide groove is oppositely provided with a guide block and a clamping block, the tail of the solder strip falls into the guide groove after the solder strip is cut off, and the second power mechanism drives the guide blocks and the clamping blocks to move face to face or back to back so as to clamp or release the solder strip located in the guide groove, so that the solderstrip is aligned with the multi-main-grid photovoltaic battery sheet. The positioning mode is accurate, the subsequent series welding effect is good, the grid line resistance is reduced, and the photoelectric conversion efficiency is improved.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a positioning device for multi-busbar photovoltaic cells and welding strips. Background technique [0002] With the development of new energy, the photovoltaic industry continues to grow, and photovoltaic cells are also developing rapidly and constantly changing. The battery assembly is formed by connecting multiple battery sheets through ribbon welding to form a battery string, and then connecting the batteries in series through confluence welding. Nowadays, after the development and innovation of solar cells, MBB (multi-busbar) solar cells have become the mainstream, and their photoelectric conversion efficiency can be increased by 0.2%, reducing costs. Moreover, MBB cells have less silver paste and thinner silver wires, saving 25%-35% of positive silver consumption. In order to reduce the influence of photovoltaic module resistance, the more precise the connection betw...
