Description

Technical Field

The invention relates to the technical field of electroplating equipment, in particular to an open type roller and a workpiece processing device.

Background

Barrel plating, namely barrel electroplating, is to place a certain number of workpieces in an inner cavity of a barrel plating barrel, and under the rotation of a barrel, the workpieces are continuously contacted with electroplating solution in a tank body, and a metal layer or an alloy coating with required thickness is deposited on the surface of the workpieces, so that the purposes of protecting the surface of the workpieces and other functions are achieved.

Open cylinder among the prior art is including setting up conductive shaft, driving shaft, driven shaft and the drive belt in the cylinder both sides, and wherein, the drive belt is around establishing on driving shaft and driven shaft and being the closed ring, and the front side outer peripheral face of drive belt both sides is around establishing in the periphery of conductive dish, encloses between the front side outer peripheral face of drive belt and two conductive dishes to have the opening and inwards sunken holding inner chamber. External drive power drive driving shaft rotates, and the driving shaft rotates and drives the drive belt rotation so that the work piece that holds the inner chamber constantly rolls, makes the plating solution of work piece and cell body and the conductive shaft contact of cylinder both sides, adsorbs metal ion completion electroplating after the work piece contact conductive shaft is electrically conductive.

However, when a small amount of workpieces are arranged in the roller, the workpieces are scattered in the roller, and part of the workpieces distributed in the middle of the roller cannot contact the conductive shafts on two sides and cannot be conductively adsorbed with metal ions in the rotating and rolling process, so that the electroplating effect is influenced; a small number of workpieces can be fully contacted with the conductive shafts on the two sides only by rolling for many times, so that the electroplating efficiency is low.

The material of the transmission belt is non-conductive material such as plastic, the electroplating solution contains cations, the workpiece to be plated is used as a cathode, the workpiece with the electroplating solution is contacted with cathode conductive shafts at two sides in the rolling process to conduct electricity, and the cations in the electroplating solution on the workpiece deposit on the surface of the workpiece through electrolysis to form a plating layer after the electricity is conducted. When a few workpieces are arranged in the roller, the conductive area of the cathode needs to be increased properly, the transmission belt cannot be directly made into a conductive material, if the transmission belt is used as the cathode, the area of the transmission belt is much larger than that of a product, most of cations are deposited on the surface of the transmission belt to form a coating, and effective and uniform electroplating of the workpieces cannot be realized; at the same time, the cation consumption is high, and the electroplating cost is greatly increased.

Still have a cylinder structure among the prior art, the cable conductor penetrates as the conducting electrode among the electroplating process in the cylinder from the both sides terminal surface of cylinder, and external power drive cylinder is rotatory, and the work piece constantly overturns in the cylinder and the contact of cable conductor accomplishes the electroplating. The roller structure has the advantage that the cable is easy to be wound with a workpiece to damage the cable or the workpiece when the cable rotates along with the roller.
