Surface treatment method

Abstract

The invention discloses a surface treatment method. The surface treatment method comprises the following steps that S1, an electroplated workpiece is placed in a recovery tank and is fixedly arrangedthrough an electroplating hanging part; and S2, the workpiece is subjected to gas washing, a plating solution on the workpiece is blown off, and the plating solution blown off from the workpiece is added back into a front plating tank to be recycled. According to the surface treatment method, through repeated recycling of the plating solution, waste of a large amount of electroplating metal copperand water is avoided, and a large amount of metal copper resources and water resources are saved.

Description

technical field [0001] The invention relates to a method for treating the surface of a workpiece containing plated metal copper on the surface. Background technique [0002] After the electroplating process is completed, the workpiece containing the plated metal copper needs to be cleaned. Most of the current electroplating process cleaning adopts the countercurrent cleaning method. The electroplated workpieces are cleaned through the recovery tank in an orderly manner according to the running direction of the production line, one countercurrent tank and two countercurrent tanks. , countercurrent three tanks, and finally flow out from one tank. Due to the large amount of water in the recovery tank, this process cannot be reused in large quantities, resulting in a lot of waste of electroplated metal copper, serious resource loss, and large water consumption. Contents of the invention [0003] The object of the present invention is to provide a surface treatment method to sa...

[0002] After the electroplating process is completed, the workpiece containing the plated metal copper needs to be cleaned. Most of the current electroplating process cleaning adopts the countercurrent cleaning method. The electroplated workpieces are cleaned through the recovery tank in an orderly manner according to the running direction of the production line, one countercurrent tank and two countercurrent tanks. , countercurrent three grooves, and finally flows out from one groove. Due to the large amount of water in the recovery tank, this process cannot be reused in large quantities, resulting in a lot of waste of electroplated metal copper, serious resource loss, and large water consumption.
