The invention relates to the technical field of wire harness processing, and discloses an electronic wire harness production line, and the production line comprises a feeding device, a processing device and a collecting device which are sequentially arranged in the wire harness advancing direction; the processing device is arranged on a workbench, and the feeding device comprises a wire harness feeding unit and a wire harness conveying unit which are sequentially arranged in the feeding direction; the processing device comprises a wire cutting unit, a feeding unit, a crimping unit and a terminal chain pushing unit. The wire cutting unit comprises a knife rest arranged on the collecting table and close to one side of the movable seat; the three cutter assemblies are arranged in parallel inthe length direction of the cutter rest, a cutter driving part is arranged on the cutter rest, a pull-back part is arranged below a movable base and used for driving the movable base to move in the width direction of the workbench, and a moving part is arranged between the collecting table and the workbench and used for driving the wire harness to move. The length direction of the knife rest is parallel to that of the workbench. The production line has the following advantages and effects that the machining procedures are integrated, and the machining efficiency is high.
