Open chain belt type barrel plating machine

Abstract

The invention discloses an electro-plating device and specifically relates to an open chain belt type barrel plating machine. The open chain belt type barrel plating machine comprises an electro-plating slot, an anode plate, a cathode plate guide wire and a control device, wherein the control device is electrically connected with the anode plate and the cathode plate guide wire respectively; the open chain belt type barrel plating machine further comprises a chain belt, a transmission wheel for driving the chain belt to move left and right and a motor; the motor is electrically connected with the control device; the chain belt is arc-shaped and arranged in the electro-plating slot; the circle centre of the circular arc where the chain belt lies is arranged above the chain belt; a plurality of liquid through holes for passing bath solution are arranged on the chain belt; and an unloading mechanism is fixed at the left side of the electro-plating slot. The open chain belt type barrel plating machine is simple in structure, high in production efficiency, good in quality of the surface of a plated part and extensive in applicative component dimension range; moreover, the chain belt for bearing components is open so as to be capable of detecting the quality of plated work pieces at any time in a working status, thereby ensuring the product yield.

Description

technical field [0001] The invention relates to an electroplating production equipment, in particular to an open chain-belt barrel plating machine. Background technique [0002] Barrel plating is drum electroplating, which is to place a certain number of small parts in a special drum, and deposit various metal or alloy coatings on the surface of the parts in a rolling state in an indirect conductive manner, so as to achieve surface protection and decoration and various functions. An electroplating processing method for the purpose. The existing barrel plating method is: put the small parts that have been pre-plated into the barrel, and the parts rely on their own gravity to press the cathode conductive device in the barrel tightly to ensure that the current required for the parts to be plated can be maintained. Then, the drum rotates at a certain speed in a certain direction, and the parts roll and fall continuously after being rotated in the drum; at the same time, the mai...

AI Technical Summary

Problems solved by technology

[0004] 1. The traditional drum is a closed structure, the ion exchange of the plating solution inside and outside the drum is difficult, the concentration in the drum decreases, resulting in low current efficiency, the increase of the tank pressure causes the temperature of the plating solution to rise, the appearance of the coating decreases, and the production time of a single coating is too long

2. The closed drum cannot detect the plating situation of the workpiece in real time, which makes it time-consuming and time-consuming for the production line to change the workpiece and line up the test plating, and the production efficiency is low

3. The electroplating solution is consumed more when the entire drum is out of the tank, so that the main metal ions in the electroplating solution are consumed faster

4. The traditional barrel plating machine needs to invest a lot of equipment costs and maintenance costs to realize the automatic production line

5. The structure of the automatic equipment for the workpiece to be plated to enter and exit the drum is complicated and the cost is high
