Description
Technical field
The present invention relates to technical field of solar cell manufacturing, particularly relate to the series connection welding method of solar battery sheet, welding production line used and welding Welding compound spraying coater used.
Background technology
The welding sequence of solar battery sheet is one of critical process during solar module is produced, it not only has strict requirement to the quality of connection between cell piece and welding, and also have very high requirement to the cleanliness factor in cell piece front, must not the impurity such as residual flux in the front of cell piece, to avoid the daylighting effect affecting cell piece.In the series winding welding process of solar battery sheet, the positive and negative of adjacent two cell pieces relatively, complete connection by same welding.As shown in Figure 1, namely when welding 5 is welded with the reverse side 3 of first piece of cell piece 1 by its upper surface 6, then welded with the front 2 of second piece of cell piece 1 by the lower surface 4 of welding 5, welded with the front of first piece of cell piece by the lower surface of another welding 5 simultaneously, welded with the reverse side of second piece of cell piece by the upper surface of this welding.The method series cells at the two sides of welding spraying scaling powder is adopted in prior art, when adopting the method series cells, need first all to coat scaling powder at the tow sides of welding, then with manipulator, cell piece is placed on the table, welding is moved to directly over cell piece, after blocking welding, welding is placed on cell piece and completes the connection of welding to cell piece, during such welding cell piece, in the welding production line of cell piece, by sucker suction welding, the welding being coated with fluxing agent is inhaled predetermined welding position, when adopting sucker suction welding, due to welding being coated with scaling powder, scaling powder very easily blocks sucker, cause welding absorption insecure or dislocation, in order to solve this technical problem, scaling powder drying device is adopted to carry out drying to scaling powder, but still inevitably cause scaling powder to block sucker hole.In order to improve above-mentioned technical problem, now with manipulator, cell piece is placed on the table, the surface of then again welding being moved to cell piece is welded, therefore, the action of placing battery plate needs certain coordinating with between the action pulling welding, otherwise two actions produce interference, will reduce the welding efficiency of cell piece like this, when adopting this method to carry out welding of battery film, the welding that can only complete 600 cell pieces per hour.
In order to improve the welding efficiency of cell piece, what extensively adopt at present is all spray scaling powder at the tow sides of cell piece, by manipulator cell piece one is transplanted on welding bench and makes cell piece one front 2 upwards, by sucker, welding is transplanted on workbench, make the upper surface 6 of welding relative with the reverse side 3 of welding, be welded to connect by the scaling powder being coated in cell piece one reverse side by the upper surface of welding one end and the reverse side of cell piece one; Then by manipulator, cell piece two is transplanted on welding bench, and the front 2 of cell piece two is upwards arranged, now the lower surface of welding and the front 2 of cell piece two are oppositely arranged, by the scaling powder be coated on cell piece front 2 welding cell piece two and welding, thus complete the connection of cell piece one and cell piece two.By sucker, another welding is transplanted on welding bench, and make the upper surface of welding relative with the reverse side of cell piece two, the upper surface of one end of another welding is connected by the scaling powder being coated in cell piece two reverse side, by manipulator, cell piece three is transplanted on welding bench again, the front of cell piece three and the lower surface of another welding are oppositely arranged, by the scaling powder being coated in cell piece three front, the front of the lower surface of the other end of another welding and cell piece three is welded to connect, completes being connected in series of other cell piece successively.Although adopt this method to improve operating efficiency, make the quantity of welding cell piece reach 900 per hour, but owing to being all spray scaling powder on the obverse and reverse two sides of cell piece, painting position due to scaling powder is difficult to accurately, or scaling powder is gradually mapped to outside precalculated position in spraying process, therefore when welding and welding of battery film complete, scaling powder can be left on the two sides of cell piece, in order to reduce the impact of residual scaling powder on the lighting performance of cell piece, need clear up by the scaling powder residual to cell piece front, which not only adds the operation of welding cell piece, reduce the efficiency of welding of battery film, and due to scaling powder cleaning not thorough, thus affect the lighting performance of cell piece, reduce the quality of cell piece.
