Step-by-step transmission of fully automatic barrel plating method and production line

Abstract

The invention relates to a fully-automatic roll plating method and production line in a step-by-step passing manner. A travelling crane and other expensive equipment are not adopted during the transferring of materials, so that the construction cost of the whole production line is low; and the upgrading renovation of an electroplating production enterprise are carried out without pressure. A rolling barrel is open, so that electric ions between a plated product and an anode can be exchanged and transferred in a barrier-free manner; and cathode conducting wires are fixedly connected, so that the lost electric energy due to the poor contact of traditional electrode hanging rods is reduced. Thus, the actual production proves that the electroplating time and the electric energy can be saved by more than 40% under the same electroplating condition by utilizing the fully-automatic roll plating method provided by the invention. The experiment proves that a product which has the same quality as the quality effect obtained by the machined product with the mill finish less than 2*2mm in a rack plating manner can be plated by the fully-automatic roll plating production line in the step-by-step passing manner. In the production line, a centrifugal dirt collector is arranged at the lower part of each cleaning tank, so that the cleaning water can be used for a long time, i.e., the discharge of sewage is reduced by 40%. Thus, the energy conservation and the environment friendliness are realized.

Description

technical field [0001] The invention relates to an electroplating method and a production line, in particular to a step-by-step automatic barrel plating method and a production line. Background technique [0002] At present, the barrel plating of electroplating enterprises is still produced with closed barrels that have not changed their structure for decades. The barrels are closed, and the fresh electroplating solution outside the barrel continuously passes through numerous small holes on the wall of the barrel. The old electroplating solution in the drum and the hydrogen generated during the electroplating process are also discharged out of the drum through these small holes. The ion exchange of the plating solution inside and outside the barrel is difficult, the concentration in the barrel decreases, resulting in low current efficiency, the increase of the tank pressure leads to the increase of the temperature of the plating solution, the decrease of the appearance of th...

AI Technical Summary

Problems solved by technology

The structure of the automatic equipment for the workpiece to be plated to enter and exit the drum is complicated and the cost is high

In this way, the solutions brought out between the processes pollute each other greatly, the water consumption of drum cleaning is large, the solution loss is large, and the production method is wasteful, which puts a lot of pressure on wastewater discharge and treatment, which is not economical and not energy-saving and environmentally friendly.
