Abstract
Description
Technical Field
[0001] This application relates to the field of electroplating technology, and more specifically, to an anode sludge removal device. Background Technology
[0002] In the current electronics manufacturing industry, electronics factories often face a thorny problem during the production process with soluble anodic VCP (vertical continuous plating) or DVCP (two-way vertical continuous plating) copper plating lines: an abnormally thin copper layer appears at the bottom edge of the board. In-depth research has revealed that the key factor causing this production defect is the excessive accumulation of anode sludge in the equipment, preventing sufficient copper ion deposition in the bottom area of the board during electroplating, thus resulting in insufficient copper layer thickness.
[0003] Currently, conventional methods used in the industry to address this issue have significant limitations. On the one hand, replacing all anode bags and copper balls every three months can alleviate the problem of anode sludge accumulation to some extent, but frequent replacements not only consume a lot of manpower and resources but also increase equipment downtime, affecting production efficiency. On the other hand, for certain sheet thicknesses, an additional production process switch is required in the third month, changing the original one-time plating process to two-stage electroplating. Specifically, after the first electroplating, the sheet must be removed, flipped, and then subjected to the second electroplating. This cumbersome process not only increases the complexity of the production process and significantly increases the difficulty of production management but also significantly increases production costs, placing considerable economic pressure on enterprises.
[0004] In view of this, the present application aims to provide an anode sludge removal device to reduce the accumulation of copper-plated anode sludge, reduce the cost of replacing anode bags and cleaning copper balls, as well as maintenance time and labor costs, thereby effectively solving the above-mentioned technical problems.

[0028] See Figure 1 As shown, the anode sludge removal device of this embodiment includes a filter assembly 1, an aeration assembly 2, and a plurality of filter modules 3 arranged sequentially along the electroplating line. Each filter module 3 contains an anode unit 4. The filter assembly 1 is connected to the anode unit 4. Each filter module 3 is provided with an aeration pipe 31 and an anode sludge suction pipe 32. The aeration section of the aeration pipe 31 and the suction section of the anode sludge suction pipe 32 are both located on the bottom side inside the anode unit 4. The aeration pipe 31 is connected to the aeration assembly 2, and the anode sludge suction pipe 32 is connected to the filter assembly 1.
[0029] This embodiment has a simple structure and reasonable design. In use, the aeration pipe 31 is used to aerate the bottom side inside the anode unit 4, so that the anode mud is suspended. Then, the suspended anode mud is sucked into the filter assembly 1 through the anode mud suction pipe 32 for filtration, so as to effectively remove the anode mud and ensure the stable operation of the electroplating process.
[0030] Specifically, the anode mud removal device in this embodiment can be activated during equipment maintenance to avoid quality problems caused by excessive turbulence of electroplating solution during production.
[0031] In some embodiments, a protective mesh structure 5 is also included, which is arranged around the bottom side and above the anode unit 4. The aeration section of the aeration pipe 31 and the suction section of the anode sludge suction pipe 32 are both located within the area enclosed by the protective mesh structure 5.
[0032] In this embodiment, by setting the protective mesh structure 5, the situation where the anode unit 4 deforms inward and blocks the suction during the extraction of anode mud can be avoided. At the same time, the internal structure of the anode unit 4, such as the anode titanium basket, can be prevented from hitting the pipeline below during installation, thus affecting the cleaning effect.
[0033] In some embodiments, the aeration section of the aeration pipe 31 is located below the suction section of the anode sludge suction pipe 32.
[0034] Specifically, the aeration section of the aeration pipe 31 aerates towards the bottom and side of the anode unit 4.
[0035] In this embodiment, since the anode mud is deposited on the bottom side inside the anode unit 4, this arrangement allows it to be sprayed towards the bottom and sides of the tank through the aeration pipe 31 to achieve a dust-raising effect, thereby enabling the anode mud suction pipe 32 to better suck it in and achieve a better cleaning effect.
[0036] In some embodiments, the filtration assembly 1 includes a delivery pipeline 11, a delivery pump 12, a centrifugal filter bag dewatering mechanism 13, a bag filter mechanism 14, and a collection tank 15. The inlet end of the delivery pipeline 11 is connected to the anode mud suction pipe 32, and the outlet end of the delivery pipeline 11 is connected to the collection tank 15. The delivery pump 12, the centrifugal filter bag dewatering mechanism 13, and the bag filter mechanism 14 are arranged sequentially along the delivery direction of the delivery pipeline 11. The collection tank 15 is connected to the anode unit 4 through a return pipe 16.
[0037] Specifically, the return pipe 16 is equipped with a circulating return pump 17.
[0038] Specifically, the centrifugal filter bag dehydration mechanism 13 has an interception filtration accuracy of 5.0 μm, and the bag filter mechanism 14 has a filtration accuracy of 1.0 μm.
[0039] In this embodiment, the extracted anode mud is first sent to the centrifugal filter bag dewatering mechanism 13 to dry and recycle the anode copper mud. The filtrate is then filtered through the bag filter mechanism 14 and returned to the collection tank 15. The filtrate in the collection tank 15 is then sent back to the anode unit 4 through the return pipe 16.
[0040] In some embodiments, the anode mud suction pipe 32 and the conveying pipe 11 are both made of transparent pipe.
[0041] In this embodiment, by using transparent tubing, operators can visually observe the flow and concentration changes of the anode mud inside the tubing, as well as any abnormal phenomena such as blockages, allowing for timely detection and handling of problems and ensuring the normal operation of the anode mud removal device.
[0042] In some embodiments, the aeration component 2 is configured as an air compressor, and the aeration pipe 31 of each of the filter modules 3 is connected to the air compressor.
[0043] In this embodiment, the aeration component 2 is set as an air compressor, and the aeration pipes 31 of each filter module 3 are connected to the air compressor. The air compressor can provide a stable air source, ensuring that the aeration pipes 31 in each filter module 3 can aerate normally, and facilitates centralized control and management of the aeration process, thereby improving aeration efficiency and stability.
[0044] In some embodiments, the anode unit 4 is provided with an anode bag, an anode frame, an anode basket and a copper ball arranged sequentially from the outside to the inside. The aeration section of the aeration pipe 31 and the suction section of the anode sludge suction pipe 32 are both located within a space within the bottom side of the anode frame with a height not exceeding 15dm.
[0045] This embodiment specifically shows that the anode unit 4, which is composed of an anode bag, an anode frame, an anode basket, and copper balls, is adopted in the prior art. Specifically, four anode titanium baskets can be used as a filter module 3. Multiple filter modules 3 are arranged in sequence to extend to the entire copper tank of the electroplating line, thereby realizing the removal of anode mud from the entire electroplating line.
[0046] Specifically, in the above embodiments, the connection positions of the various pipe fittings and pipelines can adopt existing technologies such as bolt connection, flange connection, clamp connection or heat fusion connection, as long as the strength of the connection is ensured.
[0047] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
