Tin connection prevention device

The utility model discloses a tin connection prevention device which comprises an installation plate, a knife rest mechanism fixedly installed on the upper side of the installation plate, a tin placing mechanism fixedly installed on the upper side of the installation plate and arranged on the front side of the knife rest mechanism, and a translation mechanism and a turnover mechanism fixedly installed on the upper side of the installation plate. And the output ends of the translation mechanism and the turnover mechanism are fixedly provided with a front wire stripping clamp mechanism. Through the arrangement of the front wire stripping clamp mechanism, under the constraint of the wire passing hole in the wire passing block, the wire heads of the wire are forced to be separated through the telescopic wire passing block, the phenomenon that the wire heads get close to or make contact with one another, and consequently tin connection occurs in the subsequent tin pick-up process is avoided, the linear guide rail
