Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is told about further, so that the technical solution of the utility model is more readily understood and grasps.
" embodiment 1 "
As shown in Fig. 3 Fig. 4, a kind of structuring photovoltaic welding belt, including welding matrix 1, this welding matrix 1 is flat copper wire, for the sunray in reflected illumination to welding, wherein a welding matrix 1 at least EDS maps has one or more circular arc camber extended along welding length direction, it is coated with on circular arc camber and its shape, the corresponding metallic reflector of size 2, this metallic reflector 2 is stannum layer, in order to use dip-coating process of tin, wherein circular arc camber is parallel to welding length direction, and controlled tin thickness by being coated with (plating) stannum thickness control device, thus realize freely regulating of tin thickness.Tin layers uses dip-coating process of tin, easy to process, pollution-free, tin layers solderability is preferable, certainly may be used without electroplating technology processing, be positioned at the lower section of described circular arc camber and be provided with multiple passage 3 extended towards described welding matrix 1 length direction in the most described welding matrix 1, the same side of two adjacency channels 3 is connected by union elbow, electric wire between welding and cell piece can penetrate in passage 3, thus prevents electric wire to be exposed to outer problem electric leakage and electric wire damage occur.
It addition, the cross section of circular arc camber is a circular arc, the central angle θ angular range of its circular arc is 00<θ<900, and the cross section of circular arc camber is in the same size, along welding transverse width direction in continuously without spaced apart, the cross section size of certain circular arc camber can also be inconsistent, along welding transverse width direction in continuously without spaced apart.Certainly, circular arc camber width horizontal along welding, oblique is that consecutive intervals distribution also can be implemented, above-mentioned along welding transverse width direction in being only used as the present embodiment optimal technical scheme without spaced apart continuously, but be not limited to the present embodiment.
" embodiment 2 "
