Description
Technical field
When the utility model relates to photovoltaic welding belt technical field more particularly to a kind of High-efficiency photovoltaic solder strip and its implementing welding
Screen printing apparatus used.
Background technique
Photovoltaic welding belt is also known as tin-coated copper strip or applies tin copper strips, the connection being mainly used between photovoltaic module cell piece, hair
The conductive important function for gathering electricity is waved, as shown in Figure 1, when the multi-disc cell piece 2 of photovoltaic module is connected using welding 1, it is two neighboring
The front of one of cell piece 2 is welded with the back side of welding 1 between cell piece 2, the back side of another cell piece 2 and welding 1
Front welding；
Obvious welding also problem of bring shading while converging on photovoltaic module, in order to solve this problem, mesh
Also reflective solder strip is used on preceding photovoltaic module accordingly, mainly by doing V-groove in copper-based take, by V-groove come anti-
Sunlight is penetrated, realizes the multiplexing of light, increases the power of photovoltaic module with this, has the one side of V-groove to be also referred to as decorative pattern on welding
Face can cover solder layer on its patterned surface of most welding on the market at present accordingly, on the one hand using solder layer to base band
It is protected, increases its corrosion-resistant and oxidative resistance；On the other hand using solder layer to be welded with cell piece, and solder
Problem brought by the setting of layer is as follows:
Decorative pattern since the thickness of solder layer on welding patterned surface is thicker, in the place section of welding and the welding of cell piece front
Reflective income is smaller, that is to say, that after welding, the ratio being filled with solder is fewer for V-groove, then reflective more, more increase component
Power, it is clear that the thickness of reduction patterned surface (contain V-shaped groove surface) solder layer as far as possible is then more conducive to increase power, but welds
The bed of material is too thin, but influences the welding in cell back silver face, therefore how to balance solder layer, that is, can guarantee welding, and energy
It realizes maximum reflective income, is always the reflective solder strip application problem to be solved.
Reflective solder strip on the market passes through right two major classes at present:
One is plating reflective solder strip, such welding, by doing decorative pattern in copper-based take, the then system by way of plating
Standby tin-lead solder layer, due to being that copper-based band is electroplated together, in order to guarantee the welding of back silver, solder layer generally will not be low
In 13 μm, but thickness is too thick (more than 15 μm), will lead to the severe (packing ratio of fill solder that V-groove is melted after welding
Example 40%-50%), reflective income is seldom, and therefore, this type welding patterned surface solder layer is between 13-15 μm, for 60
The component power of piece is promoted only about between 1.5-2W, and this type welding electroplating cost is high, the condition window narrows of application,
Cell piece and string welding machine slightly have fluctuation, connect bad problem with regard to will appear battery back silver soldering；
Secondly being segmented welding, V-groove decorative pattern exactly is done in copper-based take, one section of solder layer is 2-5 μm thin (for anti-
Light), one section 18-25 μm of the solder thickness welding for the cell piece back side.Such welding is the solder prepared by physics mode
Layer, advantage are that reflective power is higher, promote about 3W for 60 component powers, but this reflective solder strip is in use process
In, since the solder layer length at 18-25 μ m thick end is all inconvenient, and head and the tail both ends cell piece top edge in photovoltaic module
The length of pad and the pad at remaining position is inconsistent, therefore the welding that segmented welding can be more usual loses 5-10%,
And need to add in string welding machine and identify the device for being segmented position, the fraction defective of application is high.When being most importantly segmented, due to being to do
The solder layer of different sections, therefore production efficiency is low, stability is poor.And this mode does twill low efficiency, at high cost, stability
Difference；Chinese patent 201510386460.7 discloses a kind of photovoltaic welding belt and preparation method thereof, which actually also belongs to
In such segmented welding, this welding equally exists the above problem.
For with this, the utility model be intended to provide it is a kind of can guarantee welding, and be able to achieve maximum reflective income
Photovoltaic welding belt.

The welding quality that silver is carried on the back as welding 1 and cell piece 2 is then by welding, prepared by weld-aiding cream or tin cream
Now solder layer 3 processed is formed in the V-groove of welding 1, the welding quality of welding 1 is ensured with this, and now the thickness of solder layer 3 processed can be according to
Depending on the weld strength guaranteed on welding 1 and cell piece 2 between back silver face 2-1.
As shown in figure 5, having 5 rows 4 column in the case of the back silver face 2-1 of every cell piece 2, as shown in figure 8, the print on web plate 6
Brush mouth 6-1 equally has 5 rows 4 column, is printed simultaneously using 5 root bead bands 1,5 root bead bands 1 is correspondingly placed on pedestal 7 simultaneously, welding
1 is respectively positioned between pedestal 7 and web plate 6, and when printing is put into weld-aiding cream or tin cream in the inner cavity 5-1 of platform 5 first, then web plate
Lower air cylinder 9 directly drives platform 5 and moves down, and makes to be pressed on welding 1 under the web plate 6 on platform 5, and subsequent scraper lower air cylinder 12 is driven
Dynamic scraper 8 is pressed on web plate 6, finally drives active synchronization wheel 14 to rotate by motor 13, and drives slide using synchronous belt 16
11 is mobile, to realize movement of the scraper 8 on web plate 6, by the 5-1 of inner cavity weld-aiding cream or tin cream blow into the printing of web plate 6
Mouth 6-1 is mentioned to realize that solder layer 3 processed occurs in the position printing for the back silver face 2-1 that correspondence need to weld cell piece 2 on welding 1
Now preparation efficiency and precision of the solder layer 3 processed on welding 1 is risen, and the preparation process stability of entire solder layer 3 now processed is strong.
