The invention relates to a cleaning and electroplating all-in-one machine which comprises multiple functional tanks, a hoisting mechanism, a plating article hanging basket, a rack and an electronic control mechanism. The rack is of a rectangular frame type structure, the functional tanks are placed at the bottom of the rack side by side, and the top of the rack is provided with a pair of guide rails; the hoisting mechanism comprises a rail car, a hanging bracket and air cylinders, and the rail car is placed on the guide rails and driven by a motor to move left and right along the guide rails; the air cylinders are fixed on the rail car, and piston rods are vertically downward; the hanging bracket is fixed at the ends of the piston rods and provided with hook sets of which the number corresponds to that of the functions tanks; the bottom of the plating article hanging basket is provided with support rods side by side, and the top of the plating article hanging basket is provided with a horizontal lifting handle, so that the plating article hanging basket is lifted and moved by the hook sets; the motor and the air cylinders are controlled by the electronic control mechanism, and the rack is provided with an infrared sensor used for detecting the moving position of the plating article hanging basket and transmitting a signal to the electronic control mechanism. The cleaning and electroplating all-in-one machine has the advantages that the design is reasonable, the structure is impact, the process switching between workpiece cleaning and workpiece electroplating is operated simply, and the efficiency is high.
