Dense busbar solder strip threading device and threading method, and series welding machine

Abstract

The invention relates to a dense busbar solder strip threading device, which comprises a base, a guide track plate group, a left fixed wheel group, a right fixed wheel group, a driving wheel group, a counter weight wheel group and a guiding and driving assembly, wherein the guide track plate group is fixedly arranged on the base; the left fixed wheel group and the right fixed wheel group are fixed on the left upper end and the right upper end of the guide track plate group; the guiding and driving assembly is fixed at the outer side of the guide track plate group; the counter weight wheel group and the driving wheel group are fixed on the guiding and driving assembly; the guiding and driving assembly drives the counter weight wheel group and the driving wheel group to move up and down. When a plurality of solder strips are threaded, a driving mechanism drives the counter weight wheel group to move downwards, so that the solder strips bear gravity of counter weights, and meanwhile, driving wheels also correspondingly move downwards to positions close to a strip distributing mechanism, so that the threading operation of the dense busbar solder strips is finished at the moment. The structure positions are arranged compactly and orderly, and the solder strips can be threaded conveniently and quickly without intertwining in a limited space. The invention furthermore provides a series welding machine.

Description

technical field

[0001] The invention relates to the technical field of mechanical equipment, in particular to a strip threading device, a strip threading method and a stringer welding machine for dense grid welding strips. Background technique

[0002] At present, the social energy problem is becoming more and more severe, the decline of traditional energy reserves and the environmental problems brought about are increasingly restricting the development of the economy, and the photovoltaic industry, as the backbone of the new energy industry, is rapidly blooming everywhere in our country.

[0003] At present, three-grid and four-grid solar cells are widely used. Solar cells are semiconductor devices that convert solar energy into electrical energy. Grid wires are an important part of batteries. Experiments have shown that fine grids are more conducive to the collection of cell current and make the lateral resistance smaller, and the smaller the spacing of the fine grid lines...
