Description

Technical Field

[0001] This utility model relates to the field of electroplating solution circulation, and in particular to an electroplating solution circulation and dispersion mechanism. Background Technology

[0002] In the modern electroplating production field, the uniform dispersion of electroplating solution plays a decisive role in ensuring the quality of the coating. With the continuous improvement of the precision requirements for metal surface treatment in industries such as electronics and automotive parts, the effect of electroplating solution circulation and dispersion has become a key factor restricting the product yield.

[0003] Currently, Chinese patent CN214808914U discloses an electroplating solution circulating filter. The electroplating solution is filtered sequentially from left to right through the filter plates inside the filter grid, so that the electroplating solution is filtered multiple times in a single cycle, which increases the filtration effect and efficiency of the electroplating solution. Moreover, the device is inexpensive and easy to use.

[0004] The most widely used electroplating solution circulation and dispersion method in most industries is the traditional pump circulation. Traditional pump circulation relies on a single pipeline to transport the electroplating solution from the storage tank to the electroplating tank. Although this method can achieve basic circulation of the plating solution, the flow path of the plating solution in the electroplating tank is relatively fixed, making it difficult to form sufficient turbulence. This results in uneven distribution of additives and metal ions in the plating solution, which directly affects the gloss and uniformity of the coating. Utility Model Content

[0005] The main purpose of this invention is to provide an electroplating solution circulation and dispersion mechanism, which aims to solve the problem of the existing electroplating solution circulation and dispersion methods widely used in most industries, which are mainly traditional pump circulation. Traditional pump circulation relies on a single pipeline to transport the electroplating solution from the storage tank to the electroplating tank. Although this method can achieve basic circulation of the plating solution, the flow path of the plating solution in the electroplating tank is relatively fixed, making it difficult to form sufficient turbulence. This leads to uneven distribution of additives and metal ions in the plating solution, which directly affects the gloss and uniformity of the coating.

[0006] To achieve the above objectives, the present invention proposes an electroplating solution circulation and dispersion mechanism, which includes an electroplating tank, a spraying mechanism inside the electroplating tank, and a stirring turbine on the rear side of the inner wall of the electroplating tank.

[0007] The spraying mechanism includes two fixed pipes, several nozzles, a three-way pipe, and a pump body. The fixed pipes are fixedly connected to the inner wall of the electroplating tank. The nozzles are fixedly connected to the fixed pipes on the side closest to them. The rear side of the three-way pipe passes through the electroplating tank and is fixedly connected to the front side of the fixed pipes. The bottom of the three-way pipe is fixedly connected to the output end of the pump body. The nozzles are inclined downwards and staggered.

[0008] Preferably, a connecting pipe is fixedly connected to the rear side of the pump body, and the rear side of the connecting pipe is fixedly connected to the front side of the electroplating tank.

[0009] Preferably, a limiting card is fixedly connected to the front side of the inner wall of the electroplating tank, the limiting card is located at the rear side of the connecting pipe, a limiting mesh is embedded inside the limiting card, a connecting card is provided at the top of the electroplating tank, a connecting plate is fixedly connected to the bottom of the connecting card, a filter plate is fixedly connected to the bottom of the connecting plate, and the filter plate is movably inserted into the inside of the limiting card.

[0010] Preferably, a limit button is provided on the front side of the connecting card, and the rear side of the limit button passes through the connecting card and is connected to the internal thread of the electroplating tank.

[0011] Preferably, a servo motor is provided on the rear side of the electroplating tank, and the front side of the output shaft of the servo motor passes through the electroplating tank and is fixedly connected to the rear side of the stirring turbine.

[0012] Preferably, a first support plate is fixedly connected to the front side of the electroplating tank, the bottom of the pump body is fixedly connected to the top of the first support plate, a second support plate is fixedly connected to the rear side of the electroplating tank, and the bottom of the servo motor is fixedly connected to the top of the second support plate.

[0013] Preferably, a drain pipe is fixedly connected to the left side of the electroplating tank, and a valve is installed inside the drain pipe.

[0014] Preferably, a controller is fixedly connected to the front side of the electroplating tank.

[0015] In this invention, after injecting an external electroplating solution into the electroplating tank, the pump is activated by the controller. The pump draws the electroplating solution from the front of the tank through a connecting pipe, distributes it to the fixed pipes on both sides via a three-way pipe, and then sprays it downwards from inclined and staggered nozzles, forming a multi-angle cross jet stream. This initially disperses the electroplating solution within the tank. Simultaneously, the controller adjusts the servo motor speed according to process requirements, driving the stirring turbine to rotate and further agitate and mix the jet stream, refining the liquid flow path and enhancing the turbulence effect of the electroplating solution. This ensures that the additives and metal ions inside the external electroplating solution are evenly distributed, resulting in more uniform electroplating of the workpiece. During circulation, when the electroplating solution flows through the limit card, the limit screen and filter plate work together to intercept solid impurities, preventing them from circulating with the liquid. When the filter plate needs to be replaced, the limit button is turned out, and the connecting clip is pulled upwards to remove the filter plate from the limit card. The drain pipe is used for periodically discharging waste liquid, and the valve controls... The electroplating solution preparation and discharge process achieves efficient circulation and uniform dispersion of the electroplating solution through the synergistic effect of jet dispersion, turbine stirring, and impurity filtration. Furthermore, the filter plates are easy to replace, effectively extending the service life of the electroplating solution. This solves the problem of the widely used electroplating solution circulation and dispersion methods in most industries, which are mainly traditional pump circulation. Traditional pump circulation relies on a single pipeline to transport the electroplating solution from the storage tank to the electroplating tank. While this method can achieve basic circulation of the plating solution, the flow path of the plating solution within the electroplating tank is relatively fixed, making it difficult to form sufficient turbulence. This leads to uneven distribution of additives and metal ions in the plating solution, directly affecting the gloss and uniformity of the coating. It should be noted that the electroplating tank is a mature, publicly available technology. As a basic carrier, it needs to be used in conjunction with mature technology components such as an external power supply and heating system to complete the entire electroplating process, which will not be elaborated here. Additionally, an existing ultrasonic defoamer can be selected as needed to prevent bubbles from affecting the electroplating effect on the workpiece. Attached Figure Description

[0028] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0029] This invention provides an electroplating solution circulation and dispersion mechanism, which aims to solve the problem of the existing electroplating solution circulation and dispersion methods widely used in most industries, which are mainly traditional pump circulation. Traditional pump circulation relies on a single pipeline to transport the electroplating solution from the storage tank to the electroplating tank. Although this method can achieve basic circulation of the plating solution, the flow path of the plating solution in the electroplating tank is relatively fixed, making it difficult to form sufficient turbulence. This leads to uneven distribution of additives and metal ions in the plating solution, which directly affects the gloss and uniformity of the coating.

[0030] like Figure 1-6 As shown in the figure, the electroplating solution circulation and dispersion mechanism provided in this embodiment of the present invention includes an electroplating tank 1, a spraying mechanism 2 is provided inside the electroplating tank 1, and a stirring turbine 5 is provided on the rear side of the inner wall of the electroplating tank 1.

[0031] The spraying mechanism 2 includes two fixed pipes 201, several nozzles 202, a three-way pipe 203, and a pump body 204. The fixed pipes 201 are fixedly connected to the inner wall of the electroplating tank 1. The nozzles 202 are fixedly connected to the fixed pipes 201 on the side closest to the fixed pipes 201. The rear side of the three-way pipe 203 passes through the electroplating tank 1 and is fixedly connected to the front side of the fixed pipes 201. The bottom of the three-way pipe 203 is fixedly connected to the output end of the pump body 204. The nozzles 202 are inclined downwards and staggered.

[0032] In the technical solution of this utility model, after injecting external electroplating solution into the electroplating tank 1, the pump body 204 is started by the controller 7. The pump body 204 draws the electroplating solution from the front of the electroplating tank 1 through the connecting pipe 11, distributes it to the fixed pipes 201 on both sides through the three-way pipe 203, and then sprays it downwards from the inclined and staggered nozzles 202, forming a multi-angle cross jet flow, so that the electroplating solution is initially dispersed in the tank. At the same time, the controller 7 adjusts the speed of the servo motor 8 according to the process requirements, driving the stirring turbine 5 to rotate. The jet stream is then agitated and mixed a second time, further refining the flow path and enhancing the turbulence of the electroplating solution. This ensures a uniform distribution of additives and metal ions within the external electroplating solution, resulting in more even electroplating of the workpiece. During circulation, when the electroplating solution flows through the limit card 10, the limit mesh 15 and filter plate 14 work together to intercept solid impurities, preventing them from circulating with the liquid. When the filter plate 14 needs to be replaced, the limit button 13 is turned out, and the connecting card 3 is pulled upwards to remove the filter plate 14 from the limit card 10. The drain pipe 4 is used for periodic discharge of waste liquid, and the valve 16 controls the discharge process. Through the synergistic effect of jet dispersion, turbine stirring, and impurity filtration, the electroplating solution achieves efficient circulation and uniform dispersion. The filter plate 14 is easy to replace, which can effectively extend the service life of the electroplating solution. This solves the problem of the electroplating solution circulation and dispersion method widely used in most industries, which is mainly traditional pump circulation. Traditional pump circulation relies on a single pipe to transport the electroplating solution from the storage tank to the electroplating tank. Although this method can achieve basic circulation of the plating solution, the flow path of the plating solution in the electroplating tank is relatively fixed, making it difficult to form sufficient turbulence. This leads to uneven distribution of additives and metal ions in the plating solution, which directly affects the gloss and uniformity of the coating. It should be noted that the electroplating tank 1 is a mature technology that has been published. As a basic carrier, it needs to be used with mature technology components such as external power supply and heating system to complete the complete electroplating process. It will not be elaborated here. In addition, the existing ultrasonic defoamer can be selected as needed to avoid bubbles affecting the electroplating effect of the workpiece.

[0033] Please refer to the following: Figure 1 and Figure 3 A connecting pipe 11 is fixedly connected to the rear side of the pump body 204, and the rear side of the connecting pipe 11 is fixedly connected to the front side of the electroplating tank 1. In this embodiment, the rear side of the pump body 204 is connected to the front side of the electroplating tank 1 through the connecting pipe 11 to form an electroplating solution circulation loop. This allows the plating solution drawn by the pump body 204 to be sprayed out through the nozzle 202 and then returned to the front of the electroplating tank 1 for recirculation, ensuring continuous flow of the electroplating solution and improving circulation efficiency.

[0034] For further information, please continue to refer to [link / reference]. Figure 2 , Figure 5 and Figure 6A limiting clip 10 is fixedly connected to the front side of the inner wall of the electroplating tank 1. The limiting clip 10 is located behind the connecting pipe 11. A limiting mesh 15 is embedded inside the limiting clip 10. A connecting clip 3 is provided at the top of the electroplating tank 1. A connecting plate 12 is fixedly connected to the bottom of the connecting clip 3. A filter plate 14 is fixedly connected to the bottom of the connecting plate 12. The filter plate 14 is movably inserted into the inside of the limiting clip 10. In this embodiment, by using the limiting clip 10 on the front side of the inner wall of the electroplating tank 1 in conjunction with the limiting mesh 15 and the filter plate 14, solid impurities in the circulating electroplating solution can be intercepted, preventing them from clogging the pump body 204 and the nozzle 202. The filter plate 14 is connected to the connecting clip 3 through the connecting plate 12, which facilitates installation and disassembly and allows for regular cleaning and replacement.

[0035] Please continue to refer to this. Figure 1 and Figure 5 A limit button 13 is provided on the front side of the connecting card 3, and the rear side of the limit button 13 passes through the connecting card 3 and is threadedly connected to the inside of the electroplating tank 1. In this embodiment, by using the limit button 13 on the front side of the connecting card 3 to pass through the connecting card 3 and be threadedly connected to the inside of the electroplating tank 1, the connecting card 3 and the filter plate 14 can be securely fixed, preventing them from loosening or shifting under the impact of the circulating electroplating solution, and ensuring the stability and reliability of the filtration structure.

[0036] Please refer to Figure 1 and Figure 2 A servo motor 8 is installed at the rear of the electroplating tank 1. The front of the output shaft of the servo motor 8 passes through the electroplating tank 1 and is fixedly connected to the rear of the stirring turbine 5. In this embodiment, the servo motor 8 at the rear of the electroplating tank 1 drives the stirring turbine 5 through its output shaft, which can perform secondary stirring and mixing on the electroplating solution sprayed from the nozzle 202, enhance the dispersion effect of the electroplating solution, make the composition of the electroplating solution more uniform, and ensure the electroplating quality of the workpiece. Furthermore, the output shaft of the servo motor 8 and the electroplating tank 1 are rotated and sealed by a rotating sealing ring of existing mature technology.

[0037] Additionally, please refer to Figure 1 and Figure 2 A first support plate 6 is fixedly connected to the front side of the electroplating tank 1, and the bottom of the pump body 204 is fixedly connected to the top of the first support plate 6. A second support plate 9 is fixedly connected to the rear side of the electroplating tank 1, and the bottom of the servo motor 8 is fixedly connected to the top of the second support plate 9. In this embodiment, the pump body 204 and the servo motor 8 are supported by the first support plate 6 and the second support plate 9 respectively, ensuring that they are installed stably and reducing vibration during operation.

[0038] Please refer to Figure 1 A drain pipe 4 is fixedly connected to the left side of the electroplating tank 1, and a valve 16 is installed inside the drain pipe 4. In this embodiment, the drain pipe 4 and valve 16 on the left side of the electroplating tank 1 facilitate the quick discharge of waste liquid in the electroplating tank 1 when the electroplating solution needs to be replaced, which is beneficial to the maintenance and management of the electroplating tank 1.

[0039] Additionally, please refer to Figure 1 A controller 7 is fixedly connected to the front side of the electroplating tank 1. In this embodiment, the controller 7 on the front side of the electroplating tank 1 can centrally control the operating parameters of components such as the pump body 204 and the servo motor 8, such as adjusting the flow rate of the pump body 204 and the speed of the servo motor 8, so as to realize the intelligent control of the electroplating solution circulation and dispersion process, and improve the electroplating efficiency and accuracy. It should be noted that the controller 7 is a mature technology that has been published and will not be described in detail here.
