Strip material electroplating device

Abstract

The invention provides a strip material electroplating device. The strip material electroplating device comprises a supporting frame, a conductive wheel mechanism, a pressing wheel mechanism and a supporting wheel mechanism, wherein the conductive wheel mechanism, the pressing wheel mechanism and the supporting wheel mechanism are arranged on the supporting frame. A pressing wheel of the pressing wheel mechanism cooperates with a conductive wheel of the conductive wheel mechanism to form a rolling clamping portion. A strip material is clamped by the rolling clamping portion and is in electric contact with the conductive wheel. The rolling and clamping portion has the functions of clamping and guiding and also achieves rolling electric conduction with the strip material. A supporting wheel of the supporting wheel mechanism is located at the bottom of the strip material. The supporting wheel has the function of supporting, achieves rolling guiding of the bottom of the strip material and avoids the bottom of the strip material from conducting electricity. The strip material is not prone to being scratched, and sparks caused by friction are avoided. In this way, the quality problems, such as scratches, scorching, peeling and an uneven plating layer, caused by sliding electric conduction are fundamentally solved.

Description

technical field [0001] The invention relates to the technical field of electroplating equipment manufacturing, in particular to an electroplating device for continuous electroplating with strip materials. Background technique [0002] Continuous electroplating can improve the wear resistance, electrical conductivity, and reflective properties of the workpiece, thereby improving the practicability and decoration of the workpiece, so it is widely used, second only to rack plating and barrel plating, and its types can be divided into Partial plating, spot plating, rainbow plating, pearl plating, etc. [0003] In the prior art, the electroplating method for strip material (such as copper strip) is as follows: figure 1 As shown, the conduction mode of the current plating tank is very simple, and the copper strip 20' is guided by the insulating rods (not shown) on both sides, and the current is obtained by direct friction with the stainless steel rod 10' connected to the power su...

AI Technical Summary

Problems solved by technology

Due to the sliding friction between metals, it is easy to scratch the copper strip; the sparks generated by the sliding will also burn the copper strip, and then cause peeling; the gap between the insulating rod and the copper strip that acts as a guide is fixed, and its Excessive clearance makes the copper strip 20' easy to swing and cause uneven coating

These have seriously affected the quality pass rate of the copper strip, which also reduces the performance of the relay, and the gap is too small to cause the transmission to be blocked.
