Tinning die for photovoltaic triangular solder strip

The utility model discloses a tin plating mould for a photovoltaic triangular welding strip, which comprises an annular mould sleeve and a mould core, the mould core is arranged in the annular mould sleeve, a central constant-diameter tin-plating hole is arranged on the mould core, a plurality of convex ribs are uniformly distributed on the inner wall of the constant-diameter tin-plating hole, and the outline formed by the tops of the plurality of convex ribs is used as a constant-diameter channel of the welding strip to be tinned. And the part, except the sizing channel, of the constant-diameter tin flowing hole is a tin flowing channel. According to the utility model, the plurality of convex ribs are arranged on the inner wall of the constant-flow tin-plating hole, so that a welding strip penetrates through the constant-flow tin-plating hole, tin liquid is ensured to be uniformly scraped, the thickness of a plating layer of the welding strip is uniform, a large amount of residual soldering ...
