Description

Technical Field

[0001] This utility model belongs to the field of electroplating technology, specifically relating to a gold electroplating solution circulation device. Background Technology

[0002] Gold electroplating is a process that deposits a thin layer of gold on the surface of a metal using electrochemical methods. This process not only enhances the aesthetics of products but also increases conductivity and improves corrosion resistance. The principle of gold electroplating is that gold ions in an electrolyte are deposited on the surface of the metal to be plated under the action of an electric current, forming a thin layer of gold.

[0003] Gold plating solution contains no solid components. It is a liquid plating solution mainly composed of metal salts, complexing agents, additives, etc., and is used to form a uniform coating on the metal surface.

[0004] Currently, in order to improve the utilization rate of electroplating solution, circulation equipment is usually used to recycle the electroplating solution, and filtration and impurity removal are important functions of electroplating solution circulation equipment.

[0005] A search revealed that Chinese utility model patent CN221940679U, authorized by the patent, discloses "a circulating filtration device for electroplating solution," which includes an electroplating tank. A bracket is fixedly connected to the right side of the electroplating tank, and a box is fixedly connected to the right side of the bracket. A circulation pipe is fixedly connected to the lower end of the box, and the end of the circulation pipe away from the box is fixedly connected to the electroplating tank. A cover is slidably connected to the upper inner side of the box.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-3The present invention provides the following technical solution: a gold electroplating solution circulation device, including an electroplating platform 1 and an electroplating tank 2 fixed on the top surface of the electroplating platform 1, and further including: a storage tank 3, two circulation pumps 4 and a collection tank 7.

[0037] Furthermore, by Figure 1 and Figure 2 As shown, in this embodiment, the storage tank 3 is fixed to the top surface of the electroplating platform 1. The inlet of one circulation pump 4 is connected to the storage tank 3, and the outlet is connected to the electroplating tank 2 via an inlet hose 5. The inlet of the other circulation pump 4 is connected to the electroplating tank 2 via a return hose 6, and the outlet is connected to the storage tank 3. The collection tank 7 is installed inside the storage tank 3 by a pull-out method, and the storage tank 3 has a disassembly port 31 for the collection tank 7 to pass through. The collection tank 7 is machined with filter holes 71. With the above scheme, when using it, first inject an appropriate amount of gold electroplating solution into the storage tank 3, or directly inject the gold electroplating solution into the electroplating tank 2, and the metal parts are electroplated in the electroplating tank 2. After the electroplating is completed, start the circulation pump 4 connected to the return hose 6. The gold plating solution in the electroplating tank 2 is drawn out by the circulation pump 4. The gold plating solution passes through the return hose 6 into the storage tank 3 and enters the collection tank 7 under gravity. Impurities are trapped in the collection tank 7, while the gold plating solution passes through the filter hole 71. The circulation pump 4 connected to the inlet hose 5 is started. The circulation pump 4 draws out the gold plating solution in the storage tank 3 and returns it to the electroplating tank 2 through the inlet hose 5. This utility model uses the collection tank 7 with filter hole 71 to filter the recovered gold plating solution and temporarily recover the intercepted impurities. The filter hole 71 is located on the side wall of the collection tank 7, which is not easy to clog. In addition, the collection tank 7 is installed by a pull-out method, which is easy to install, use and disassemble for cleaning, which helps to improve work efficiency.

[0038] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the outer wall of the collection box 7 abuts against the inner wall of the disassembly port 31. After adopting the above solution, the stability of the collection box 7 during use can be further improved, and the collection box 7 can be prevented from shaking or shifting during operation.

[0039] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, it also includes: positioning strips 32, two positioning strips 32 are symmetrically fixed in the liquid storage tank 3, and the collection box 7 is located below the positioning strips 32. After adopting the above solution, when in use, the two positioning strips 32 further position the installation position of the collection box 7 from above, which further improves the stability of the installation of the collection box 7.

[0040] Preferably, by Figure 1 and Figure 2As shown in this embodiment, the positioning strip 32 is an "L"-shaped component. The two positioning strips 32 correspond to the left and right corners of the top of the collection box 7, respectively. With the above solution, the "L"-shaped positioning strip 32 can clamp the collection box 7 from both sides during use, further improving the stability of the collection box 7 installation.

[0041] It should be noted that, for the collection box 7 of this utility model, when the collection box 7 is in the installed state, the embedded end face of the collection box 7 abuts against the inner wall of the liquid storage tank 3, which can be understood as the length of the collection box 7 being equal to the width of the liquid storage tank 3.

[0042] Preferably, by Figures 1-3 As shown, this embodiment also includes: a limiting plate 72, a positioning screw 9, and a wing nut 10.

The two positioning screws 9 are symmetrically fixed to the outer wall of the liquid storage tank 3, and the positioning screws 9 pass through the positioning holes 722. The wing nut 10 is installed on the protruding end of the positioning screw 9 by thread engagement. With the above scheme, when using, after pushing the collection box 7 into the liquid storage tank 3, the positioning screw 9 passes through the positioning holes 722. Then, the wing nut 10 is tightened on the protruding end of the positioning screw 9 to lock the collection box 7, thus achieving stable installation of the collection box 7. After unscrewing the wing nut 10, the collection box 7 can be pulled out for cleaning, which is convenient to use.

The rubber sealing ring 11 is bonded and fixed to the outer wall of the liquid storage tank 3 at the position corresponding to the disassembly port 31 and facing the limiting plate 72. After adopting the above solution, when the collection box 7 is installed, the limiting plate 72 cooperates with the liquid storage tank 3 and clamps the rubber sealing ring 11, causing the rubber sealing ring 11 to shrink, which further improves the sealing performance of the collection box 7 after installation and avoids leakage accidents.

[0044] Preferably, by Figures 1-3 As shown, this embodiment also includes a handle 721, which is fixed to the outer wall of the limiting plate 72. With the above solution, the collection box 7 can be easily pulled out from the liquid storage tank 3 by the handle 721 during use.

[0045] Preferably, by Figure 1 and Figure 2As shown, this embodiment also includes a top plate 8, which is fixed to the top of the liquid storage tank 3 with bolts, and a liquid replenishment port 81 is fixed on the top plate 8.
