A full-automatic wire rod single-end terminal press fitting wetting machine disclosed by the present invention comprises a rack, a terminal conveying and press fitting mechanism, a branching mechanism, a wire rod moving mechanism, a wire cutting, peeling and twisting mechanism, a wire pulling and clamping mechanism and a wetting mechanism. The rack is equipped with a workbench, the wetting machine utilizes the wire rod moving mechanism to move the wire rods to the branching mechanism and the terminal conveying and press fitting mechanism to branch the wires and press fit the terminals, and then the wire rods are cut, peeled, twisted, wetted with the soldering flux and the tin, so that the above mechanisms are integrated on the rack, and all the wire rods can be separated and straightened before the terminals are press fitted, and accordingly, the terminals and the wire rods are riveted more accurately and firmly. The wire rods can be cut, peeled and twisted automatically, so that the wire rod processing efficiency is improved. Moreover, the wire rods are wetted with the soldering flux and the tin automatically, so that that the operations of branching, terminal press fitting, cutting, peeling, twisting, wetting with soldering flux and tin of the wire rods all can be finished automatically, the artificial workload and the production cost are reduced, and the production efficiency is improved.
