Problems solved by technology

Not only will it cause the conductive copper plate to glow red and hot, but it will even cause the workpiece to be burned out and deformed; it will also pose a threat to the cooling system of the electroplating solution; in addition, the high current will increase the equipment investment of the electroplating power supply
[0005] Secondly, the conduction of multiple anodes at the same time will also cause the problem of uneven conduction.
Due to the large number of anodes, it is inevitable that the conduction ability of the current will be affected due to the different degrees of copper plate surface oxidation and lead anode surface passivation, thus affecting the average distribution of current.
This will cause the problem of uneven thickness of the electroplating layer of the workpiece.
[0006] Thirdly, in fixed anodic plating, the thickness of the electroplating layer is uneven, forming the defect of saddle-shaped electroplating layer
[0007] 2) The barrel plating electroplating process has the disadvantage that it can only electroplate cylindrical workpieces; during the electroplating process, the workpiece will be exposed to the surface of the solution, resulting in a greater risk of poor bonding of the coating; more electroplating auxiliary tools are required, and the tooling Inconvenient loading and unloading, easy to cause damage to electroplated parts
[0008] 3) The mobile cathodic electroplating process has the following disadvantages: it is only suitable for electroplating of small pieces, but it is not easy to realize for large pieces; for a production line, it can only be electroplated for shaped products, which has poor versatility
[0010] In the general mobile anodic plating process, because the anode moves at a constant speed according to the parameters set in advance, it cannot be dynamically adjusted according to the size of each section of the workpiece, so it is impossible to accurately control the coating thickness of each section of the workpiece
[0011] 5) Continuous electroplating has its disadvantages: a set of equipment can only plate stereotyped products, and its adaptability to different products is weak; the loss of sealing sleeves is relatively large; the unplated part of the workpiece is outside the solution, and if it is not handled properly, it will cause Oxidation will affect the adhesion of the coating

Description

technical field [0001] The invention belongs to the technical field of electroplating equipment, and in particular relates to an electroplating device with variable speed movement of an anode. 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 material parts to prevent Metal oxidation (such as rust), improve wear resistance, electrical conductivity, reflective properties, corrosion resistance (copper sulfate, etc.) and enhance the appearance. The outer layer of many coins is also electroplated. The traditional electroplating tank structure diagram is as follows: figure 1 As shown, the traditional electroplating mainly has the following methods: [0003] 1) Fixed anodic plating process, which has the following disadvantages: [0004] First of a...
