Soldering system of waste printed-circuit board

The invention relates to the technical field of waste processing of electrical and electronic products, and discloses a soldering system of a waste printed-circuit board. The soldering system comprises a plurality of working grooves, tracks and a shifting device, wherein the working grooves are arranged in a single row and used for holding soldering solution of the waste printed-circuit board respectively; the tracks are positioned above the working grooves and arranged along the working grooves; and the shifting device comprises a bracket and a clamping mechanism used for clamping the waste printed-circuit board, wherein the bracket is assembled on the track in a sliding manner, and the clamping mechanism is assembled on the bracket in a sliding manner and can slide relative to the bracket in the height direction and a horizontal direction perpendicular to the track. The soldering system has the benefits that the shifting device improves the working efficiency of the waste printed-circuit board, and massive
