A drum electroplating device

Abstract

The invention discloses a drum electroplating device, which comprises a bracket and a drum. The drum is a hollow structure, and two ends of the drum are respectively formed or fixedly connected with an end cover, and the drum is rotatably connected to the bracket through the two end covers. ; It also includes two conductive mechanisms that cooperate with the two end covers one by one, and the two conductive mechanisms respectively include conductive bearing bushes, planar conductive parts and conductive shafts for connecting cables; the conductive parts are installed on the end caps. On the inner end face, the conductive shaft is fixed on the end cover and is located at the rotation axis of the end cover. The conductive shaft is electrically connected to the conductive part; the conductive bearing is located outside the drum and is pressed against the side of the conductive shaft by an elastic positioning mechanism. . The present invention adopts the above-mentioned structure, which not only has minimal wear and durability, saves the material cost and maintenance cost of frequent replacement of electric wires in the prior art, but also solves the problem of deformation of small and thin parts due to the impact of electric wires, and reduces The labor cost of subsequent manual classification of defective parts is reduced.

Description

technical field [0001] The invention relates to an electroplating device, in particular to a drum 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 barrel plating can only be used to achieve mass production. [0003] It is a common practice in the industry to use electric wires to conduct electricity in drum plating equipment. The drum electroplating equipment of prior art is as figure 1 , figure 2 As shown, the end caps 11' at both ends of the drum 1' are respectively connected with the shaft sleeve 3' and the shaft core 4' to rotate with the bracket 2'. Specifically, the shaft sleeve 3' is fixed to the end cap 11' of the drum by screws. Together, the shaft core 4' is fixed together with the bracket 2' through the ...
