Abstract
Description
Technical Field
[0001] The utility model relates to the field of electroplating equipment, in particular to an inner cavity flow plating equipment for a rotating workpiece. Background Art
[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to adhere a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics.
[0003] For workpieces made of hollow pipes, existing electroplating equipment completely immerses the workpieces in the electroplating solution for electroplating. Firstly, the electroplating is uneven, and secondly, the electroplating effect on the inner wall of the pipe is poor.
[0004] In 2004, the applicant applied for an electroplating machine unit. In this structure, liquid storage tanks are arranged above and below the barrel, and a plating liquid flow channel is formed between the lower liquid storage tank, the inner cavity of the barrel and the upper liquid storage tank. An anode that moves in the vertical direction is connected to the top of the barrel, and a number of electrodes are connected to the side walls of the barrel. The inner wall of the barrel is electroplated by flowing electroplating liquid. Compared with the original solution of completely immersing the workpiece in the electroplating liquid for electroplating, the electroplating effect of the inner wall of the pipe is significantly improved, but it still has the problem of uneven electroplating. Utility Model Content
[0005] In order to solve the problems of the prior art, the utility model provides an inner cavity flow plating device for a rotating workpiece, which drives a barrel to rotate through a spinning mechanism to make the electroplating of the inner wall of the barrel more uniform.
[0006] The utility model comprises a base, wherein a lower liquid storage tank is arranged at the bottom of the base, a barrel is connected to the middle of the base, an upper liquid storage tank and an electrode rod are arranged at the upper part of the base, the electrode rod passes through the upper liquid storage tank and extends into the inner cavity of the barrel and is arranged concentrically with the barrel, a plating liquid flow channel is formed between the lower liquid storage tank, the inner cavity of the barrel and the upper liquid storage tank, a motor-driven spinning mechanism is arranged in the middle of the base, the spinning mechanism clamps the outer wall of the barrel and drives the barrel to rotate around its own axis; an electrode rotating with the barrel is attached to the outer wall of the barrel.
[0007] As a further improvement, the barrel rotation angle is -360°~360°. Taking the initial position as a reference, the barrel rotation does not exceed one circle forward and backward, and can rotate alternately forward and backward within this range.
[0008] As a further improvement, the spinning mechanism clamps the middle of the barrel, and the electrodes are attached to the outer wall of the barrel and are symmetrically distributed with the spinning mechanism as the axis of symmetry.
[0009] The working process of this utility model is as follows:
[0010] 1. Fix the barrel through the spinning mechanism so that the barrel is connected with the upper and lower liquid storage tanks;
[0011] 2. The electrode rod moves downward into the inner cavity of the barrel, concentric with the barrel, and moves up and down in the inner cavity;
[0012] 3. The electroplating liquid is introduced into the liquid inlet of the lower liquid storage tank, and the electroplating liquid enters the upper liquid storage tank through the barrel and is discharged from the upper liquid storage tank;
[0013] 4. Install electrodes on the barrel and carry out the electroplating process. During the electroplating process, the barrel is based on the initial position and rotates no more than one circle forward and backward. It can rotate forward and backward alternately within this range;
