Description

The welding feeding mechanism of the automatic string welding machine of solar battery sheet

Technical field

The utility model embodiment is related to the automatic string welding machine technical field of solar battery sheet, more particularly to a kind of solar energy The welding feeding mechanism of the automatic string welding machine of cell piece.

Background technology

With the lifting of the degree of automation, the automatic string welding machine of solar battery sheet all begins to take on the welding supply of automation Device, existing welding feeding mechanism mainly include：For load welding material volume and externally export welding discharge mechanism, apply help weldering Agent mechanism, reshaping device, welding bending mechanism, cutting mechanism and material pulling mechanism, welding is clamped by the fixture of material pulling mechanism End is dragged so that is cut after the coated solder of welding of discharge mechanism output, shaping, bending at cutting mechanism It is disconnected, and material pulling mechanism also keeps clamping the welding short-movie for being cut off and moves further into overlapping station, then welding is short Piece discharge to be placed in advance overlapping station solar cell on piece, then material pulling mechanism return again at cutting mechanism again The end for clamping welding carries out next actuation cycle.

Above-mentioned existing welding feeding mechanism can be suitably used for welding during relatively large sized solar battery sheet series welding Supply, however, when want series welding solar cell chip size it is relatively small when, its required welding short strip size of correspondence also can phase Should reduce, at this time, the part that welding short-movie is exposed at outside the fixture of material pulling mechanism may be very short, and fixture itself have it is certain Thickness so that at overlapping station, the welding short-movie of fixture clamping relative to solar battery sheet be it is hanging, it is loose at this time When driving fixture release welding short-movie, under welding short-movie from eminence equivalent to being thrown, it is not easy to accurately fall in solar battery sheet Welding position, so as to influence follow-up welding quality.

To adapt to the supply requirement of this small size welding short-movie, existing another kind welding feeding mechanism, its using The material pulling mechanism for the fixture that can be overturn with 180 degree, fixture after the first side position clamps the welding short-movie that cutting mechanism cuts around Trunnion axis overturns 180 degree, and be moved to overlapping station the outer end that welding short-movie is not clamped is taken put it is flat to overlapping is placed in Solar cell on piece at edge of table, then fixture unclamps return, while welder is to being stacked with the solar energy of welding short-movie Cell piece implements welding, welding short-movie is connected with solar battery sheet, then will be welded with welding short-movie by conveying mechanism Solar battery sheet remove, and put new solar battery sheet at overlapping platform edges, start that next to put welding short The actuation cycle of piece.This welding feeding mechanism can make the welding short-movie height that fixture clamps and solar battery sheet substantially flat Together, align it is relatively accurate, however, it is desirable to solar battery sheet is placed in the flat edge of table of overlapping, using overlapping on the outside of platform Space keep away bit space to provide rotation for fixture, occupied space is big, is unfavorable for the miniaturization of equipment, and can only often put one Welding short-movie is just stacked after row's solar battery sheet, and must be first welded at overlapping platform edges again after stacking welding short-movie Solar battery sheet remove and can just put new solar battery sheet, the inefficiency of whole motion flow.
