[0002] Electroplating solution refers to a liquid that can expand the cathode current density range of metals, improve the appearance of the coating, and increase the anti-oxidation stability of the solution. Electroplating solution usually includes main salt, complexing agent and distilled water.

[0003] Because different types of plating solution formulas require different ingredients, the specific methods of preparation are also different. They should be prepared correctly according to the specific preparation process and precautions. However, the various preparation methods and sequences are roughly the same.

[0004] The following basic requirements are usually followed:

[0005] After adding about 50% volume of distilled water into the plating tank, gradually add the calculated amount of complexing agent, conductive salt and other chemicals under stirring conditions to dissolve them in the water. It should also be heated or cooled in time to promote the complete dissolution of the chemicals.

[0006] Dissolve the calculated amount of main salt chemicals in the above formula. You can also make a paste with a small amount of distilled water in another container before adding it. The main salt should be added after the complexing agent is added to fully ensure the dissolution and complexation of the main salt.

[0007] Dissolve additives, plating solution formula, brightener and other chemicals in separate containers, and then add the above.

[0008] After adding distilled water to the specified volume and adjusting the pH value, the electroplating should be filtered, analyzed and adjusted, and then energized. After the test plating is qualified, it should be used normally. Therefore, in view of these current situations, it is urgent to develop an electroplating liquid adding device to meet the needs of actual use. Utility Model Content

The present invention is described in detail below in conjunction with the drawings.

[0031] See also Figure 1-6 A specific electroplating liquid adding device is provided, comprising a tank body 1, a liquid filling chassis 2 and a pipeline structure 3. The interior of the tank body 1 is a hollow mixing chamber. The liquid filling chassis 2 is arranged at the bottom end of the mixing chamber. The bottom end surface of the liquid filling chassis 2 is provided with a downwardly protruding connecting column 23. The center of the connecting column 23 is a hollow solution through hole 21. The solution through hole 21 and the mixing chamber are in a conducting structure. A plurality of liquid preparation through holes 22 are opened in the middle of the liquid filling chassis 2. The liquid preparation through holes 22 penetrate the top end surface and the bottom end surface of the liquid filling chassis 2. The pipeline structure 3 comprises a solution tube body 32, a liquid outlet tube body 33, a salt solution tube body 31 and a coordination liquid tube body 34. Figure 1 and Figure 2 As shown;

[0032] One end of the solution tube body 32 is arranged on the side wall of the connecting column 23, and one end of the liquid outlet tube body 33 is arranged at the bottom end of the connecting column 23. The liquid outlet tube body 33 and the solution tube body 32 are both connected to the solution through hole 21. One end of the saline tube body 31 and the coordination liquid tube body 34 are arranged on the bottom end surface of the liquid injection chassis 2, and the saline tube body 31 and the coordination liquid tube body 34 are respectively connected to the corresponding liquid through hole 22. The middle parts of the saline tube body 31, the coordination liquid tube body 34 and the liquid outlet tube body 33 are all provided with an electromagnetic valve 311, and the middle part of the solution tube body 32 is provided with a diaphragm valve 321. Figure 4 and Figure 5 shown.

[0033] The present application discloses an electroplating liquid adding device, in which a pipeline structure 3 composed of a solution tube body 32, a liquid outlet tube body 33, a salt solution tube body 31 and a coordination liquid tube body 34 is arranged inside a tank body 1, and is respectively injected into the tank body 1 through a solution through hole 21 and a coordination liquid through hole 22 in a liquid injection bottom plate 2, so that the solution (distilled water), the main salt solution and the coordination liquid can be merged into the tank body 1 in an orderly and quantitative manner.

[0034] At the same time, the solution tube 32 is injected into the tank body 1 from bottom to top through the solution through hole 21. During the injection process, the solution tube 32 can collide and mix with the main salt solution and the coordination liquid in the tank body 1, and a sufficient mixing effect can be achieved without the need for manual stirring.

[0035] Specifically, Figure 2As shown, the solution through hole 21 and the connecting column 23 are arranged at the center of the liquid injection bottom plate 2, the liquid distribution through hole 22 is opened at the periphery of the solution through hole 21, and the top surface of the liquid injection bottom plate 2 is also provided with a sinking circular groove, which is opened at the periphery of the solution through hole 21.

[0036] The top of the tank body 1 is provided with a cover plate 8, and the top surface of the cover plate 8 is provided with an air inlet interface 81, which penetrates the top surface and the bottom surface of the cover plate 8, and is connected to the mixing chamber.

[0037] The top surface of the liquid injection bottom plate 2 is also provided with a sealing gasket 9, specifically, as Figure 6 As shown, the sealing gasket 9 is fixedly connected along the periphery of the liquid filling chassis 2. When the liquid filling chassis 2 is connected to the bottom end of the tank body 1, the sealing gasket 9 is clamped between the liquid filling chassis 2 and the tank body 1. The sealing gasket 9 can effectively improve the sealing performance between the liquid filling chassis 2 and the tank body 1.

[0038] In a further scheme, a detection mechanism 4 is further provided on one side of the tank body 1, and the detection mechanism 4 includes a conducting tube body 41, a first sensor 43 and a second sensor 44. Corner joints 42 are provided at both ends of the conducting tube body 41, and the two ends of the conducting tube body 41 are respectively connected to the top of the tank body 1 and the connecting column 23 through the corner joints 42. The first sensor 43 is arranged at one end of the conducting tube body 41 close to the connecting column 23, and the second sensor 44 is arranged at one end of the conducting tube body 41 close to the top of the tank body 1, wherein the first sensor 43 and the second sensor 44 can be composed of water level sensors or pH sensors.

[0039] By electrically connecting the first sensor 43 and the second sensor 44 to the solenoid valve 311 and the electronic components controlling the diaphragm valve 321, the water level signal or the pH value signal can be used as the start signal of the solenoid valve 311 and the diaphragm valve 321 through the first sensor 43 and the second sensor 44, so that the solution (distilled water), the main salt solution and the coordination liquid can be merged into the tank body 1 in an orderly and quantitative manner.

[0040] The working process of an electroplating liquid adding device is as follows: pre-configured coordination agent and other auxiliary agents are passed through, and the main salt solution is injected into the interior of the tank body 1 through the coordination liquid pipe body 34 to the liquid distribution through hole 22; when the water level signal of the first sensor 43 is triggered, the solenoid valve 311 of the coordination liquid pipe body 34 is closed, and the solenoid valve 311 of the salt liquid pipe body 31 is opened at the same time; the pre-configured main salt solution is injected into the interior of the tank body 1 through the salt liquid pipe body 31 to the liquid distribution through hole 22; when the water level signal of the first sensor 43 is triggered, the solenoid valve 311 of the salt liquid pipe body 31 is closed, and the solenoid valve 311 of the isolation pipe body 31 is opened at the same time. Diaphragm valve 321, the solution (distilled water) is injected into the interior of the tank body 1 through the solution tube body 32 to the solution through hole 21. During the injection process, it can be impacted and mixed with the main salt solution and the coordination liquid in the tank body 1, and the effect of sufficient mixing can be achieved without the need for manual stirring. When the water level in the conductive tube body 41 reaches the position of the second sensor 44, the second sensor 44 can detect the pH value of the plating solution in the conductive tube body 41. When the pH value of the plating solution reaches a suitable range, the second sensor 44 feeds back a corresponding electrical signal, thereby closing the diaphragm valve 321.
