Electroplating method capable of automatically and continuously supplementing liquid

Abstract

The invention provides an electroplating method capable of automatically and continuously supplementing liquid. The method comprises the following steps that firstly a workpiece to be electroplated ishung, an electroplating anode and an electroplating cathode are connected, then electroplating liquid is added and an adjusting lead screw (135) is screwed to keep the buoyancy of a floating ball (133) balanced with the tensile force of the adjusting lead screw (135), thereby achieving the goal of sensing the concentration of the electroplating liquid; then transmission equipment (4) is started for performing electroplating, a circulating water pump (122) is continuously started in the electroplating process to keep the concentration of the electroplating liquid uniform, meanwhile, along withthe proceeding of the electroplating process, the concentration of the electroplating liquid is reduced, the electroplating liquid is supplemented through the sensing of a sensing device (13), the dosing of a dosing device (2) and the uniform mixing of a circulating device (12), and finally, electroplating is completed; and a power supply of the transmission equipment (4) is firstly turned off, and then a power supply between a plating material metal anode and a cathode of an electroplating bracket (3) is turned off. The method is high in automatic assembly line degree, high in electroplatingefficiency, wide in application range and high in practicability.

Description

technical field [0001] The invention relates to the technical field of electroplating processing, in particular to an electroplating method for automatic and continuous liquid replenishment. Background technique [0002] Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. It is a process of using electrolysis to attach a layer of metal film to the surface of metal or other materials to prevent metal oxidation ( Such as rust), improve wear resistance, electrical conductivity, reflective properties, corrosion resistance (copper sulfate, etc.) and enhance the appearance. [0003] At present, in the existing electroplating process, most of the operations need to be carried out manually, such as the pendant before electroplating and the pick-up after electroplating, the power-on, concentration detection and replenishment of the electroplating solution during the electroplating proces...

Problems solved by technology

[0003] At present, in the existing electroplating process, most of the operations need to be carried out manually, such as the pendant before electroplating and the pick-up after electroplating, the power-on, concentration detection and replenishment of the electroplating solution during the electroplating process, etc. The automation of the entire process is low and manual Process breakpoints are prone to occur during operation, resulting in low process continuity, wasting manpower and material resources while increasing the electroplating operation time; at the same time, the electroplating process of the prior art mostly uses original station hangers, and lowers the hangers and workpieces to the electroplating pool. After electroplating, lift the hanger and workpiece, and then remove the hanger and workpiece, the overall electroplating efficiency is low, and assembly line production cannot be realized

In the existing electroplating process, there is also electroplating of anode insoluble metals (such as electroplating chromium), which needs to consume metal ions (ie chromium ions) in the electroplating pool to complete the electroplating; in order to ensure the quality and efficiency of electroplating, it is necessary to manually check the concentration of the electroplating solution regularly. detection and replenishment, so as to avoid the problems of decreased electroplating efficiency and low electroplating quality due to the decrease of electroplating solution concentration; Such as chromium ions) are mostly heavy metals or toxic and harmful ions, which are likely to affect the health of operators. Third, if operators do not operate properly, it is easy to leak or lose the electroplating solution in the air, causing environmental pollution

[0004] Therefore, for the current electroplating process as a whole, it still has a low degree of automation and cannot fully realize assembly line production. Higher, easy to cause damage to human health and environmental pollution
