In another further preferred embodiment, described embossing device also comprises makes the compact arranged fastener of described sheet metal.
In a preferred embodiment, described embossing device is by making with the nonwettable material of melting scolding tin, or described embossing device surface coverage has and the nonwettable material thin-layer of melting scolding tin.
In further preferred embodiment, the described and nonwettable material of melting scolding tin is stainless steel, pottery, glass or enamel.
In a preferred embodiment, the surface roughness Ra of described v-depression is less than 30 μ m.
After photovoltaic welding belt welding in prior art, welding surface texture is level and smooth, cause people to be incident upon the lip-deep light of photovoltaic welding belt and be directly reflected solar module, cause light the not high enough phase of utilization ratio this, the surface that embossing device of the present utility model contacts with photovoltaic welding belt has V-type groove, thereby be used in conjunction with welder in welding process, can be by the concavo-convex pattern of special angle reflection ray in welding surface formation, making to be incident to the lip-deep light of photovoltaic welding belt reflects by special angle, part reflection ray can produce total reflection and again incide solar battery surface at photovoltaic module upper surface, patterned structure of the present utility model has improved the utilization rate of incident light, the corresponding efficiency that improves photovoltaic module.
In addition, consider the direct v-depression in embossing device Surface Machining 10 μ m to 100 μ m sizes, machining accuracy is had relatively high expectations, production cost is also higher, the angle that the utility model provides the first edge at sheet metal to go out to need by cutting, attrition process, by after sheet metal close-packed arrays, form the technical scheme of v-depression again.
