To achieve these goals, the present invention is to realize by the following technical solutions: a kind of light having moulding fancy
Volt brazing band, including continuous print burnishing surface and the fancy face having moulding, burnishing surface, fancy face repeatability or the intersection edge of discontinuity
The length direction of described welding extends, and fancy face is the concavo-convex relief fabric at interval, and burnishing surface, the bottom surface in fancy face are and light
The plane of volt silicon wafer welding.
As preferably, the lobe in described fancy face is flat configuration or acute angle, does not limit angle and the pattern of projection, i.e.
Fancy moulding whether which kind of kenel, as long as the conduction of heat demand in Automatic Production Line welding time point face can be met.
The processing technology of a kind of photovoltaic brazing band having moulding fancy, photovoltaic brazing band is by rotating shaft fancy roller and rotating shaft
The rolling of formula support roller forms, and rotating shaft fancy roller surface uses the structure that the patterned flank of tooth is crisscross arranged, rotary shaft support roller with bright finish
For full bright finish riding wheel structure；By the copper strips that need to process along rolling between the two, the described patterned flank of tooth, the arc length of bright finish and
The fancy face of photovoltaic brazing band, the length of burnishing surface keep consistent.
Beneficial effects of the present invention: (1) is made into one in the preparation section of machine at photovoltaic welding belt, copper cash is through flattening → quenching
→ embossing → tin plating → winding operation, and this embossing device is beneficial to realize the production line balance of the tin plating welding of photovoltaic, wherein embossing
Operation is simple, convenient raising production efficiency；
(2) the photovoltaic brazing band utilizing this embossing device to make can recycle light source, improves generating efficiency；
(3) using the structure that burnishing surface is arranged in a crossed manner with fancy face innovatively, the ridge design on fancy face can improve it
Poly-electro ultrafiltration, strengthens light source effect, and the smooth structure in bottom is convenient weld with cell silicon chip, it is ensured that during welding firm surely
Fixed, take into account Automation of Welding technological process and the conducting function of himself.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
Detailed description of the invention, is expanded on further the present invention.
With reference to Fig. 1-7, this detailed description of the invention by the following technical solutions: a kind of photovoltaic brazing band having moulding fancy,
Including continuous print burnishing surface A with have the fancy face B, burnishing surface A of moulding, fancy face B repeatability or the intersection of discontinuity along described
The length direction of welding extends, i.e. burnishing surface A and the fancy face B such repeated overlapping indefinite extension having moulding, described fancy
Face B is the concavo-convex relief fabric at interval, and burnishing surface A, the bottom surface of fancy face B are the plane welded with photovoltaic silicon wafer C.
The lobe that it should be noted that described fancy face B is flat configuration or acute angle, does not limit angle and the type of projection
Formula, i.e. fancy moulding whether which kind of kenel, as long as the conduction of heat demand in Automatic Production Line welding time point face can be met
?；Such as Fig. 2, Fig. 3, the bottom surface of copper strips contacts with photovoltaic silicon wafer C, and part protruding for fancy face B is the most smooth or acute angle,
As long as the conduction of heat demand with robot welding system heat conduction pressing plate D point face when producing welding can be met.
Angle effect between the B concave projection volt of this detailed description of the invention fancy face is to play more to fill by the irradiation of light
Point, make the most repeatedly be irradiated by light source between concavo-convex fluctuating to be heated and reflect, such as Fig. 4, Fig. 5, glass E covers on copper strips,
Photovoltaic silicon wafer C is welded on copper strips bottom surface, and sunray is irradiated on the fancy face B of copper strips, and light is through copper strips fancy moulding angle
Reflexing on bottom cover glass E, light impinges upon on photovoltaic silicon wafer C after glass E reflects, and recycles light source, i.e. reflects
Light can be refracted to again on the lighting surface of assembly silicon wafer of photovoltaic generation by the glass on welding again, make silicon wafer battery
The purpose being more heated is to strengthen generating efficiency.
In photovoltaic copper strip, the major function of burnishing surface A is to ensure that photovoltaic band and photovoltaic silicon crystal slate F weld on automatic production line
Firm stable when connecing, when the smooth face of weld in bottom surface of photovoltaic silicon crystal slate F welds with burnishing surface A phase.
The processing technology of a kind of photovoltaic brazing band having moulding fancy, described photovoltaic brazing band is by the rotating shaft fancy on top
The rotary shaft support roller I rolling of roller H and bottom forms, and the surface of rotating shaft fancy roller H uses patterned flank of tooth H1 and bright finish H2
The structure being crisscross arranged, rotary shaft support roller I is then full bright finish riding wheel structure；Copper strips J edge need to be processed roll between the two,
Described patterned flank of tooth H1, the arc length of bright finish H2 keep consistent with the length of the fancy face B of photovoltaic brazing band, burnishing surface A, this copper
Preparation is simple for welding, easy to operate.
This detailed description of the invention uses the structure that burnishing surface is arranged in a crossed manner with fancy face innovatively, concavo-convex on fancy face
Decorative pattern can improve its poly-electro ultrafiltration, it is possible to recycles light source, strengthens light source effect, improves generating efficiency；And bottom is smooth
Structure convenient weld with cell silicon chip, it is ensured that firm stable during welding, be smooth compared to existing surface on the market
Smooth common bright finish welding or surface are concave-convex type welding, and welding utilizes the photovoltaic welding belt machine of being made into one to make, copper
Line is through flattening → quenching → embossing → tin plating → winding process, and the photovoltaic brazing band that this embossing device makes has taken into account welding certainly
Dynamic metallization processes flow process and the conducting function of himself, the more convenient production line balance of the tin plating welding of photovoltaic, there is wide city
Field application prospect.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these become
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and
