Abstract

The invention provides a metal plating part surface continuous cleaning process which includes the steps: rust removal; washing; oil removal; washing. The invention further provides a metal plating part surface continuous cleaning control system which comprises a data input module, an instruction output module and a PLC (programmable logic controller). The data input module comprises an approach switch, a liquid level sensor, a temperature sensor and an emergency switch, and the instruction output module comprises a first motor, an electric heater, a second motor and a draught fan. According to the metal plating part surface continuous cleaning process and the metal plating part surface continuous cleaning control system, the qualification rate of an electroplated metal plating part can be increased and reaches 99%, water is saved, the water consumption of the process for cleaning metal plating parts is about half of that of a conventional method, and resources are saved.

Description

technical field [0001] The invention relates to the technical field of cleaning metal plating parts, in particular to a continuous cleaning process and control system for the surface of metal plating parts. Background technique [0002] Metal surface treatment can effectively improve and enhance the performance of the original metal without increasing too much cost. In recent years, with the continuous improvement of the technological level of metal surface treatment, its application range has become more and more extensive. The electroplating process is a technology that uses the principle of electrolysis to deposit a metal coating with good adhesion but different properties from the base material on mechanical products; electroplating is a mature surface treatment technology that uses the principle of electrolysis to deposit on some metal surfaces The process of plating a thin layer of other metals or alloys, through electrolysis, attaches a layer of metal film to the sur...
