Rolling barrel electroplating device

Abstract

The invention discloses a rolling barrel electroplating device. The rolling barrel electroplating device comprises a bracket and a rolling barrel; the rolling barrel is a hollow structure, and the two ends of the rolling barrel are respectively molded or fixedly connected with end covers; and the rolling barrel is rotationally connected to the bracket through the two end covers. The rolling barrel electroplating device further comprises two electric conducting mechanisms matched with the two end covers one to one; the two electric conducting mechanisms respectively comprise electric conducting bearing bushes for connecting with cables, surface-shaped electric conducting parts and electric conducting shafts; the electric conducting parts are mounted on the inner end surfaces of the end covers; the electric conducting shafts are fixed on the end covers, and are positioned on the rotating axis of the end covers; the electric conducting shafts are electrically connected with the electric conducting parts; and the electric conducting bearing bushes are positioned out of the rolling barrel, and are tightly pressed on the side surfaces of the electric conducting shafts through elastic positioning mechanisms. The rolling barrel electroplating device adopts the structure, is less in wear and durable, saves the material cost and the maintenance cost caused by frequent replacement of electric leads in the prior art, solves the problem of deformation of small sheet type parts due to the beating of the electric leads, and reduces the labor cost caused by subsequent classification of bad parts through labors.

Description

technical field [0001] The invention relates to an electroplating device, in particular to a barrel electroplating device. Background technique [0002] With the development of relay products in the direction of miniaturization and precision, the parts in relay products are getting smaller and thinner. The surface plating of metal parts is not suitable for rack plating because the parts are too small, and only barrel plating can be used to achieve mass production. [0003] It is a common practice in the industry for drum electroplating equipment to use electrical wires to conduct electricity. The prior art drum electroplating equipment such as figure 1 , figure 2 As shown, the end covers 11' at both ends of the drum 1' are respectively connected to the bracket 2' by the shaft sleeve 3' in cooperation with the shaft core 4'. Specifically, the shaft sleeve 3' is fixed to the end cover 11' of the drum through screws At the same time, the shaft core 4' is fixed with the bra...

Problems solved by technology

[0004] Yet the problem that above-mentioned drum electroplating equipment brings is: firstly, electric wire 5 ' stirs inside drum 1 ', realizes electric conduction function and beats parts like hammer again at the same time, just the deformation rate of parts increases greatly, especially For small and thin parts

Secondly, the electric wire 5' itself is also very easy to be twisted and damaged, resulting in frequent replacement and high material and labor costs.

These are contrary to the development direction of the surface plating of relay products
