The utility model relates to a conveying line for detecting the electrical property of a battery cell module. The system comprises a detection transport line, a rotary translation line, an unqualifiedtransport line and a plurality of qualified transport lines, the detection conveying line comprises an incoming material conveying belt, a material blocking mechanism, a material clamping mechanism and a detection mechanism. The material blocking mechanism, the material clamping mechanism and the detection mechanism are arranged on the incoming material conveying belt. The rotary translation linecomprises a translation sliding rail, a translation slider, a rotary cylinder, a jacking cylinder and a transition conveying belt, the translation slider can slide relative to the translation slidingrail, the rotary cylinder is arranged on the translation slider, the jacking cylinder is connected with the movable end of the rotary cylinder, and the transition conveying belt is fixed to the movable end of the jacking cylinder. According to the conveying line for detecting the electrical property of the battery cell module, a mode that the rotary translation line is switched back and forth between the unqualified conveying line and the plurality of qualified conveying lines is adopted, so that qualified products and unqualified products are separated, errors are avoided, the labor is reduced, and the working efficiency is improved.
