摘要：使用刷镀机构能在它垫或刷与被镀的作用相对运动从而让它获得了镀层方法。刷镀机的基本原理是和电镀机器一样的，正常工作的时候是零件为阴极，将要镀层上去的金属或者不溶性的导电材料作为阳极，再阳极的外层需要包裹一层吸水性好的纤维材料，使用垫或刷的方式，以便让其吸附镀液，当阳极和零件表面接触的的时候，它们会产生不听的相对运动，此时，电流通过阳极和自己想要镀层的材料吸附镀液，金属就会慢慢地沉积在零件的表面，从而完成镀层，随着时间的累积，程度也会慢慢地加厚，刷镀的均匀性是靠电流的密度，镀液的流量，刷镀的时间长短和阳极的移动速度来决定的。74975

目前，各种的刷镀机构已经应用于广泛的范围，是一种新的刷镀机构，适用于五金刷镀，电解，氧化，抛光等等的作用， 它所镀的表面镀层比较坚固，附着力强，对金属等的镀件也有修补，使其表面变得光滑。

Design of Brush Plating Mechanism for Automatic Brush Plating Machine

Abstract：The use of a brush plating mechanism in its pad or brush and the role of the relative movement of the plating so that it obtained a coating method The basic principle of the brushing machine is the same as that of the electroplating machine。 When the normal working part is the cathode, the metal or insoluble conductive material to be plated is used as the anode, and the outer layer of the anode needs to be wrapped with a layer of absorbent material , The use of pad or brush in order to allow it to absorb the bath, when the anode and parts of the surface contact, they will not listen to the relative movement, this time, the current through the anode and the material you want to plating the plating solution , The metal will slowly deposited on the surface of the parts, thus completing the coating, with the accumulation of time, the degree will slowly thicken, brush plating uniformity is by the current density, bath flow, brush plating The length of time and the speed of the anode to decide。

At present, a variety of brush plating mechanism has been applied to a wide range, is a new brush plating mechanism for metal brush plating, electrolysis, oxidation, polishing and so on, it is coated with a more solid surface coating Strong focus on the metal and other plating also repair, so that the surface becomes smooth

Key words: Brush plating mechanism, coating, widely used
