The invention discloses a surface treatment production line of copper products. The surface treatment production line comprises a conveying rail which is arranged along a straight line, wherein a processing slot group distributed along the straight line is arranged below the conveying rail; the processing slot group comprises a hot dipping oil removing slot, a first rinsing slot, a pickling slot, a second rinsing slot, a passivation slot, a third rinsing slot, a lead washing slot and a fourth rinsing slot which are sequentially and adjacently arranged; an electrical conveying mechanism which can reciprocate along the conveying rail and is provided with a lifting rack is matched and arranged on the conveying rail; and the electrical conveying mechanism is controlled by an electrical control system. By adopting the scheme, when the surface treatment production line of the copper product works, the electrical conveying mechanism sequentially lifts or moves a turnover basket filled with the copper products, so that the turnover basket sequentially dips into each corresponding processing slot to perform corresponding surface treatment on the copper products according to the surface treatment requirements of the copper products. Compared with the prior art, the surface treatment production line has the advantages of lower labor intensity of a worker, and high production efficiency.
