Technical problem to be solved by the invention is to provide a kind of clever structure, it is simple for production, can improve cell piece power generation
The welding of the high power gain of efficiency.
The present invention is achieved through the following technical solutions:
A kind of welding of high power gain, the welding include a Copper-Aluminum compound base and the tin-lead for being wrapped in Copper-Aluminum compound base
Layer, the aluminium foil layer that the Copper-Aluminum compound base includes a copper foil layer and is compounded on copper foil layer by roll-in, the Copper-Aluminum compound
On surface where the aluminium foil of base, also pressure is equipped with twill, and twill angle meets 120 ~ 135 degree, and oblique angle direction is along welding side
To, or with welding direction formed angle, angle is at 25 ~ 60 degree.
Preferably, the twill is the twill of triangular structure.
Preferably, the twill in the Copper-Aluminum compound base is continuous or segmentation.
Preferably, the Copper-Aluminum compound base before twill is pressed on surface with a thickness of 0.1-0.3mm, wherein aluminium foil layer
With a thickness of 30-40um, width 0.8-12mm.
The invention also discloses the production methods of the welding of above-mentioned high power gain, comprise the following steps:
(1) aluminium foil layer is pressed into Copper-Aluminum compound base material by roller with copper foil layer, the Copper-Aluminum compound base material after pressing
Expect thickness 0.1-0.3mm, wherein aluminium foil layer with a thickness of 30-40um, width 0.8-12mm；
(2) by one side where the aluminium foil of Copper-Aluminum compound base material by rolling with structured roller, by uppermost aluminium foil
Upper extrusion twill structure, this structure are continuous or are made into segmentation according to actual needs；
(3) technical process of the Copper-Aluminum compound base material of structure out Jing Guo tinning will be rolled, make Copper-Aluminum compound base material
Tin-lead welding material i.e. in Wire wrap forms finished product.Since aluminium foil layer will not generate with tin-lead compound, finished product is remained
Structure, and non-structural region is all filled with by tin-lead.
The beneficial effects of the present invention are:
High power gain welding clever structure of the invention, by the way that aluminium foil is pressed into Copper-Aluminum compound base by roller with copper foil
Layer, twill structure is then extruded on the aluminium foil of Copper-Aluminum compound base, then will roll the Copper-Aluminum compound substrate surface of structure out
Tin-lead welding material is superscribed, which will not generate compound characteristic using aluminium foil layer and tin-lead, therefore obtain finished product guarantor
The effect of twill structure has been stayed, and non-structural region is all filled with by tin-lead, therefore when in use, it can be by welding
The twill structure allows welding to have anaclasis effect, and the light reflected is reflected on panel, then the electricity on side is reflected by panel
Pond on piece, the light that multiple reflection comes facilitate the power for increasing the cell piece beside welding, provide generating efficiency, technical process
Succinctly, at low cost, environmental protection is practical, is worthy to be popularized.
Detailed description of the invention
The present invention is described in detail by following specific embodiments and drawings for ease of explanation,.
Fig. 1 is the structural schematic diagram of the Copper-Aluminum compound base of the embodiment of the present invention 1；
Fig. 2 is the structural schematic diagram of the Copper-Aluminum compound base of the embodiment of the present invention 2.
Specific embodiment
Embodiment 1
As shown in Figure 1, a kind of welding of high power gain, the welding includes a Copper-Aluminum compound base and is wrapped in Copper-Aluminum compound
The tin lead layer of base, the aluminium foil layer 2 that the Copper-Aluminum compound base includes a copper foil layer 1 and is compounded on copper foil layer 1 by roll-in,
On surface where the aluminium foil of the Copper-Aluminum compound base, also pressure is equipped with twill 3, and twill angle meets 120 ~ 135 degree, oblique angle side
Angle is formed to along welding direction, or with welding direction, angle is at 25 ~ 60 degree.
The twill 3 is the twill of triangular structure.
Twill 3 in the Copper-Aluminum compound base is continuous.
The Copper-Aluminum compound base before twill is pressed on surface with a thickness of 0.1-0.3mm, wherein aluminium foil layer with a thickness of
30-40um, width 0.8-12mm.
The production method of the welding of above-mentioned high power gain, comprises the following steps:
