As described in the background section, since the solder strip has a certain yield strength, an operator often occurs that the solder strip is completely cooled and solidified when the solder strip is not pressed to a solder point at the solder joint between the solder strip and the bus bar after welding in the welding process, and the solder strip is deformed and rebounded after welding, so that the phenomena of solder joint debonding and insufficient soldering occur, the quality of the photovoltaic module is affected, and the product yield of the photovoltaic module is reduced.
In view of the above, the present application provides a photovoltaic module welding auxiliary strip, please refer to fig. 2, and fig. 2 is a schematic structural diagram of the photovoltaic module welding auxiliary strip according to an embodiment of the present application.
The photovoltaic module welding auxiliary strip comprises a strip main body 1 and a magnet 2 embedded in the strip main body 1, wherein the strip main body 1 is provided with a first through hole 3 corresponding to the position of a welding strip and a second through hole 4 corresponding to the position of a bus bar protrusion.
It should be noted that, in the present embodiment, the shape of the second through hole 4 is not particularly limited, and may be set by itself as long as it is ensured that the bus bar protrusion can pass through the second through hole 4 and is not damaged. For example, the shape of the second through hole 4 may be circular, or elliptical, or rectangular, etc.
Preferably, the first through hole 3 is a horn-shaped through hole, and the end with the smaller aperture of the first through hole 3 is close to the solder strip.
The reason why the first through hole 3 is set to be the horn-shaped through hole is that firstly, the distance from the edge of the end with the smaller aperture of the first through hole 3 to the edge of the batten main body 1 is increased, so that the batten main body 1 is not easy to break, namely, the firmness of the batten main body 1 is increased, the service life of the batten main body 1 is prolonged, and the cost is saved; second, the less one end in 3 apertures of first through-hole is close to weld the area, when welding area and busbar welded promptly, the electric iron got into first through-hole 3 from the great one end in 3 apertures of first through-hole, made things convenient for operating personnel to operate very much, improved welding efficiency.
In the present embodiment, the number of the magnets 2 in the slat main body 1 is not particularly limited, as long as the photovoltaic module welding auxiliary slat and the laminated template are attracted to each other, so as to reduce the yield strength of the solder strip. Similarly, in this embodiment, the position of the magnet 2 inside the slat main body 1 is not particularly limited, and may be set by itself.
Preferably, magnet 2 is including being located respectively the first magnet at lath main part 1 both ends and being located the second magnet in the middle of lath main part 1, lath main part 1 is inside to be inlayed and is had three magnet promptly, is two first magnets that are located lath main part 1 both ends and is located the second magnet in the middle of lath main part 1 respectively for photovoltaic module welds supplementary lath and range upon range of template and reaches better inter attraction's effect, and the quantity of magnet also can not be too much simultaneously, reduces photovoltaic module welds the manufacturing cost of supplementary lath.
It should be further noted that, in this embodiment, the number of the first through holes 3 is not specifically limited, and the number of the first through holes 3 is equal to the number of the solder strips on a single battery piece. Similarly, the number of the second through holes 4 is not specifically limited in this embodiment, and the number of the protrusions on the bus bar used when the battery strings are combined into the battery array is determined, so that it is ensured that all the protrusions of the bus bar pass through the second through holes 4, and the protrusions are not damaged.
Optionally, on the basis of any one of the above embodiments, in an embodiment of the present application, the number of the first through holes 3 is 54, and the number of the second through holes 4 is 3. For a 9-grid photovoltaic module, nine solder strips are arranged on each cell, when the cell strings are stacked, welded and combined into a cell array, the number of the cell strings is generally 6, so that the number of the first through holes 3 is 54, the protruding positions of the bus bars are respectively located between the first cell string and the second cell string, between the third cell string and the fourth cell string, and between the fifth cell string and the sixth cell string, that is, the number of the second through holes 4 is set to 3, so that the condition can be met.
The photovoltaic module welding auxiliary strip provided by the embodiment comprises a strip main body 1 and a magnet 2 embedded in the strip main body 1, wherein the strip main body 1 is provided with a first through hole 3 corresponding to the position of a welding strip and a second through hole 4 corresponding to the position of a bus bar protrusion. The supplementary lath of photovoltaic module welding in this embodiment passes through magnet 2 and range upon range of template inter attraction for solder strip and busbar are pressed from both sides tightly, can reduce the yield strength of solder strip, weld solder strip and busbar through first through-hole 3, realize the fixed of solder strip and busbar, can effectively avoid appearing rosin joint, the condition of desoldering, promote photovoltaic module's product percent of pass.
