Description

Technical Field

[0001] The utility model belongs to the technical field of metal surface treatment, and in particular relates to a stirring device for electroplating liquid. Background Art

[0002] Electroplating solution is a chemical solution used in electroplating process, which usually contains metal salts, additives and other ingredients. Electroplating solution applies electric current to the metal surface, so that metal ions are deposited on the metal surface to form a uniform metal film to improve the appearance, corrosion resistance and other properties of the metal. Common electroplating solutions include chrome plating solution, nickel plating solution, copper plating solution, etc. Electroplating solution is widely used in surface treatment processes in industries such as automobiles, electronics, and aerospace.

[0003] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to attach a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics. The electroplating solution mainly includes main salt, conductive salt, buffer, complexing agent, additives, etc. Different electroplating solutions have different composition ratios.

[0004] However, in the above prior art, the electroplating solution needs to be mixed and stirred after it is proportioned. The current mixing and stirring work is done manually, which has low work efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A stirring device for electroplating liquid, comprising:

[0007] Tank;

[0008] Paddle mechanism;

[0009] A connecting frame, used for connecting the paddle mechanism to the tank body;

[0010] The driving mechanism has an output end connected to the paddle mechanism and drives the paddle mechanism to rotate to stir the electroplating solution temporarily stored in the tank.

[0011] Furthermore, at least two of the paddle mechanisms are provided, and the planes where two adjacent paddle mechanisms are located are arranged at an angle.

[0012] Furthermore, the tank body is connected with a driving gear matched with the driving mechanism and a driven gear meshed with the driving gear, and the rotating shaft in each of the paddle mechanisms is respectively connected with the corresponding driven gear.

[0013] Furthermore, a plurality of spoilers are arranged on the inner side of the blade mechanism, and the spoilers are arranged at equal intervals along the width or length direction of the blade mechanism.

[0014] Furthermore, the spoilers are symmetrically distributed on the inner side of the blade mechanism, and the spoilers on each side are inclined in opposite directions.

[0015] Furthermore, the paddle mechanism is rectangular in shape, and a reinforcement plate is connected to the inner side of the paddle mechanism.

[0016] Furthermore, the tank body is provided with a plurality of liquid inlet valves.

[0017] Furthermore, a liquid outlet valve is provided at the bottom of the tank body.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] By arranging a paddle mechanism in the tank body, the plating solution in the tank body is efficiently stirred to prevent the metal salt in the plating solution from precipitating or crystallizing in the solution. It also helps to maintain the uniform temperature distribution of the plating solution and ensure the uniform mixing of the chemical components in the plating solution, thereby improving the quality and stability of the plating solution.

[0020] The paddle mechanism set at an angle prevents the plating liquid from flowing in the same direction during the stirring process, and the stirring is more uniform. At the same time, during the forward or reverse rotation of each paddle mechanism, the spoiler can push the plating liquid upward or downward, so that the plating liquid flows along different liquid levels, so that the plating liquid is stirred more uniformly as a whole.

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] Among them, the drawings are only used for exemplary explanations, and they only show schematic diagrams rather than actual drawings, and cannot be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted, and the same or similar reference numerals in the drawings of the embodiments of the utility model correspond to the same or similar parts; in the description of the utility model, it should be understood that if the terms "upper", "lower", "left", "right", "inner", "outer" and the like appear, the directions or positional relationships indicated are based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, so the terms describing the positional relationship in the drawings are only used for exemplary explanations, and cannot be understood as limitations on this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0028] like Figure 1 - Figure 3 As shown, a stirring device for electroplating liquid of the utility model comprises a tank body 1, a paddle mechanism 2, a connecting frame and a driving mechanism 4;

[0029] Among them, several liquid inlet valves 10 are arranged on the tank body 1, and a liquid outlet valve 11 is arranged at the bottom of the tank body 1. According to the matching conditions of various materials in the electroplating solution, the liquid is introduced into the tank body 1 through the connection between the pipeline and the liquid inlet valve 10.

[0030] The connecting frame is used to connect the paddle mechanism 2 inside the tank body 1;

[0031] The output end of the driving mechanism 4 is connected to the paddle mechanism 2 and drives the paddle mechanism 2 to rotate to stir the electroplating liquid temporarily stored in the tank 1. The driving mechanism 4 adopts a servo motor.

[0032] To further improve the stirring effect and efficiency of the electroplating solution, the paddle mechanism 2 can be set to two or more, and the planes where two adjacent paddle mechanisms 2 are located are set at an angle. In this embodiment, two paddle mechanisms 2 are set, and the angle between them is 90 degrees.

[0033] By arranging a paddle mechanism 2 in the tank body 1, the plating liquid in the tank body 1 is efficiently stirred to prevent the metal salt in the plating liquid from precipitating or crystallizing in the solution. It also helps to maintain a uniform temperature distribution of the plating liquid and ensure that the chemical components in the plating liquid are evenly mixed, thereby improving the quality and stability of the plating liquid.

[0034] The tank body 1 is connected with a driving gear 5 matched with the driving mechanism 4 and a driven gear 6 meshed with the driving gear 5, and the rotating shaft 7 in each blade mechanism 2 is respectively connected with the corresponding driven gear 6. Through the cooperation of the driven gear 6 and the driving gear 5, the power of the driving mechanism 4 is distributed to the blade mechanism 2 respectively.

[0035] In addition, a plurality of spoilers 20 are arranged on the inner side of the blade mechanism 2 , and the spoilers 20 are arranged at equal intervals along the width or length direction of the blade mechanism 2 .

[0036] The paddle mechanism 2 set at an angle prevents the plating liquid from flowing in the same direction during the stirring process, and the stirring is more uniform. At the same time, during the forward or reverse rotation of each paddle mechanism 2, the spoiler 20 can push the plating liquid upward or downward, so that the plating liquid flows along different liquid levels, so that the plating liquid is stirred more uniformly as a whole.

[0037] Specifically, the spoilers 20 are symmetrically distributed on the inner side of the blade mechanism 2, and the spoilers on each side are inclined in opposite directions.

[0038] The paddle mechanism 2 is rectangular in shape, and a reinforcing plate 21 is connected to the inner side of the paddle mechanism 2. The reinforcing plate 21 is tilted to divide the outer frame of the paddle mechanism 2 into a triangle shape, thereby improving the overall stability of the paddle mechanism.

[0039] The above are only embodiments of the utility model. The common sense such as the known specific structures and characteristics in the scheme is not described in detail here. The ordinary technicians in the relevant field are aware of all the common technical knowledge in the technical field to which the utility model belongs before the application date or priority date, can obtain all the existing technologies in the field, and have the ability to apply the conventional experimental means before that date. The ordinary technicians in the relevant field can improve and implement the scheme in combination with their own abilities under the enlightenment given by this application. Some typical known structures or known methods should not become obstacles for the ordinary technicians in the relevant field to implement this application. It should be pointed out that for the technicians in this field, without departing from the structure of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
