Description

Technical Field

[0001] The invention belongs to the technical field of electroplating, and in particular relates to an electroplating device for conveniently collecting residual anode electroplating material and a use method thereof. Background Art

[0002] The titanium basket is a kind of hanger used to hold anodes on electroplating equipment. For example, when copper plating is required, the titanium basket will hold copper balls as anodes and the cathodes as plated parts. After direct current is applied, the copper balls in the titanium basket will gradually dissolve, while titanium is very stable and will not be dissolved. Therefore, the titanium basket is a commonly used anode hanger for electroplating.

[0003] During electroplating, the copper balls at the bottom of the titanium basket usually dissolve and shrink first. The shrunken copper balls no longer participate in the reaction due to passivation and other reasons. For example, in some electroplating processes, the copper balls stop dissolving when they shrink to about 10mm and no longer continue to shrink, which leads to a reduction in the anode area. Therefore, the electroplating tank should regularly add copper anodes (copper balls) and remove the smaller copper balls at the bottom to maintain the anode area.

[0004] When copper balls need to be replaced or added during electroplating, it is often necessary to lift the titanium basket to remove the copper balls from the plating solution for collection of all or a reduced portion of them. This operation is rather cumbersome, requiring not only the corresponding lifting mechanism to collect the copper balls from the titanium basket, but also the screening of the smaller copper balls, which are both cumbersome processes and affect production efficiency to a certain extent.

[0005] In view of this, it is necessary to provide a device that can collect or screen the residual copper balls without lifting the titanium basket. Summary of the invention

[0006] The purpose of the present invention is to provide an electroplating device which can conveniently recycle residual anode electroplating materials such as small copper balls and ensure the anode area without lifting the titanium basket.

[0017] Preferably, it also includes a power system for driving the feeding screw to rotate.

[0018] Preferably, the power system comprises a power unit and a transmission device, and the power unit is a hand crank or a motor.

[0019] Preferably, a valve is provided on the residual material output pipe.

[0020] Preferably, the portion of the residual material output pipe outside the electroplating tank is inclined, and a first valve and a second valve are provided on the portion, and the first valve is higher than the second valve; wherein the first valve is arranged close to the electroplating tank, and the second valve is arranged close to the material receiving tank, and the portion of the residual material output pipe between the first valve and the second valve forms a residual material accommodating portion.

[0021] A method for using an electroplating device with a single valve for conveniently collecting residual anode electroplating materials, characterized in that it includes the following steps: when collecting residual materials, starting a power system, opening the valve, the power system driving the feeding screw to rotate, the residual materials entering the conveying device through a residual material outlet, and then being collected to a material receiving trough through a residual material output pipe, the material receiving trough separating the residual materials and the liquid medicine, and the liquid medicine recovery pipeline re-discharging the separated liquid medicine into the electroplating tank.

[0024] 1. No need to lift the titanium basket, the residual anode plating material can be easily recovered, ensuring the continuity of electroplating production, which is not only conducive to simplifying the structure of electroplating equipment, but also conducive to improving production efficiency.

[0025] 2. Taking copper plating as an example, it was found during production that the copper balls at the bottom of the titanium basket began to dissolve and shrink first. The conveying device designed according to this characteristic limits the diameter of the residual material outlet or residual material inlet to 9-12mm, so that only the copper ball residual material of the corresponding diameter (this smaller copper ball residual material no longer participates in the reaction) can pass through, and the larger copper balls continue to stay in the titanium basket and continue to participate in the reaction. At the same time, it also makes room for the newly added copper balls, which is conducive to ensuring sufficient anode area and ensuring the quality of electroplating.

[0026] 3. A double valve is set on the residual material output pipe. Normally, the first valve is open and the second valve is closed. The power system is started intermittently to allow the residual material to enter and be temporarily stored in the residual material storage part. When collecting the residual material, first close the first valve and then open the second valve to release the residual material. This can greatly reduce the outflow of the medicine when collecting the residual material, effectively prevent the liquid level in the electroplating tank from dropping, and ensure the smooth progress of production.
