Description

Technical Field

[0001] The utility model relates to the technical field of proportioning devices, and more specifically to a precise metering and proportioning device for electroless nickel plating. Background Art

[0002] Electroplating is the process of coating 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 adhere a 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 (such as copper sulfate), and enhancing aesthetics. Existing electroless nickel plating solution preparation is usually done manually by staff. The problem caused by this manual preparation is that staff cannot accurately control the amount of prepared materials, which affects product quality.

[0003] In response to the above problems, regarding the technical problem that the staff cannot accurately control the amount of prepared materials during manual preparation, thereby affecting the quality of the product, after a lot of searches, a patent application number 202221606557.6 of a precise metering and proportioning device for electroless nickel plating was found, which belongs to the field of proportioning devices and includes a frame, a proportioning tank is provided inside the frame, and an adding tank is fixedly connected to the top of the frame; the utility model controls the closing of the first infusion tube by providing a corresponding solenoid valve, and slowly adds the liquid through the second infusion tube until the configuration is completed. The whole process realizes continuous feeding configuration and effectively improves the accuracy of metering and proportioning. However, the technical solution provided by the patent has the following problems:

[0004] After various liquids enter the mixing tank through the infusion tube, they are usually in a relatively static state and will not move in the mixing tank. If two or more liquids enter the mixing tank without stirring, the different liquids may be unevenly distributed in the tank. During electroplating, this uneven mixing state will directly affect the effect of electroless nickel plating, and inconsistent coating thickness may occur. Some areas may have too thick coatings due to excessive concentration of a certain component, while other areas may have thin coatings due to insufficient components. This not only affects the appearance quality of the product, but may also affect the performance of the coating.

[0005] The utility model can play the role of stirring and mixing the liquids in the proportioning tank through automatic rotation after two or more liquids are put into the proportioning tank and the proportioning is completed, so that the various components are fully integrated and local concentration differences are avoided, thereby providing a stable and uniform plating solution for the subsequent electroless nickel plating process.

[0014] Beneficial effects:

[0015] 1. By installing a solenoid valve and a flowmeter, the solenoid valve can quickly open or close according to the control system's instructions, thereby accurately controlling the timing and flow rate of the chemical liquid flowing out of the feed box. When proportioning is required, the control system sends a signal to the solenoid valve to open the solenoid valve, allowing the liquid to flow out smoothly. When liquid flow is not required, the solenoid valve closes to ensure that the liquid does not accidentally leak. The flowmeter monitors the liquid flow in real time. It can accurately measure the flow rate of the chemical liquid passing through and promptly feeds this data back to the control system. Based on the flow data fed back by the flowmeter and the preset proportion, the control system accurately controls the liquid flow by adjusting the opening of the solenoid valve to ensure that each chemical liquid can flow out and proportion according to the predetermined proportion.

[0016] 2. The rotating rod, gears and rotating wheels are provided. The rotating rod rotates under the drive of the motor. Several gears are fixedly installed at equal distances on the surface of the rotating rod and rotate synchronously with the rotation of the rotating rod. The gears are engaged with the rotating wheels. When the gears rotate, they can drive the rotating wheels to rotate. The rotation of the rotating wheels transmits the power of the rotating rod and gears to the auxiliary rod, so that the auxiliary rod can perform the stirring action. On the other hand, the rotation speed and direction of the rotating wheel can be adjusted by the speed of the gears and rotating rod, thereby realizing the control of the stirring intensity and effect.

[0017] 3. An auxiliary rod, bearing 1 and bearing 2 are provided. Bearing 1 is installed at the upper end of the rotating wheel, and the bottom of the fixed rod is embedded in bearing 1. When the rotating rod rotates, the inside of the sleeve rotates with the rotation of the rotating rod, while the surface of the sleeve is in a stationary state, providing a fixed support force for the fixed rod. The setting of bearing 1 makes the connection between the fixed rod and the rotating wheel more flexible, reduces friction and wear, and ensures that the rotating wheel can stably drive the auxiliary rod to rotate. Bearing 2 is embedded and installed at the bottom of the proportioning box. The bottom of the auxiliary rod is connected to bearing 2. Bearing 2 provides a stable support and rotation basis for the auxiliary rod, so that the auxiliary rod can rotate smoothly in place. At the same time, the high precision and low friction characteristics of bearing 2 ensure the rotation accuracy and stability of the auxiliary rod, further improving the stirring effect and the accuracy of the proportioning;

[0018] 4. In summary, this electroless nickel plating precise metering and proportioning device is provided with structures such as gears, rotating wheels, auxiliary rods and blades. The gears rotate under the drive of the motor and transmit power to the rotating wheel through engagement with the rotating wheel. The rotation of the rotating wheel further drives the auxiliary rod to rotate. The blades on the surface of the auxiliary rod stir the chemical liquid in the proportioning box as the auxiliary rod rotates, so that different chemical liquids can be mixed together quickly and evenly, ensuring the quality of electroless nickel plating. At the same time, by accurately measuring the flow rate of the chemical liquid, the accuracy of the proportioning can be guaranteed to meet the electroplating needs under different process requirements.

The feed box 2 is located at the upper end of the shelf above the inside of the cabinet and is used to store different chemical liquid raw materials. The number of feed boxes 2 can be adjusted according to actual needs to meet the requirements of different formulas. The solenoid valve 3 and the flow meter 4 are provided. The flow meter 4 is installed on the discharge pipe 203 below the feed box 2, the solenoid valve 3 is used to control the outflow of the liquid, and the flow meter 4 can accurately measure the outflowing liquid flow. Through the cooperation of the solenoid valve 3 and the flow meter 4, accurate measurement of each chemical liquid can be achieved. The motor 103 is fixedly installed at the left end of the proportioning box 102, and the output end of the motor 103 is fixedly connected to the rotating rod 104, and a number of gears 105 are fixedly installed on the surface of the rotating rod 104.

When the gear 105 rotates, it can drive the auxiliary rod 5 to rotate through the rotating wheel 501. When performing metering and proportioning, different chemical raw materials are first injected into different feed boxes through the feed pipe 202. Inside the material box 2, the solenoid valve is then opened to allow the liquid inside the feed box 2 to flow from the feed box 2 into the discharge pipe 203.

[0026] In the embodiment of the present utility model, a sleeve 502 is provided above the rotating wheel 501, a fixed rod 503 is fixedly installed at the bottom of the sleeve 502, a bearing 504 is embedded in the upper end of the rotating wheel 501, the sleeve 502 is nested in the surface of the rotating rod 104 and is rotatably connected to the rotating rod 104, the bottom of the fixed rod 503 is embedded in the internal connection of the bearing 504, a bearing 2 506 is provided at the bottom of the auxiliary rod 5, the bearing 2 506 is embedded in the bottom of the proportioning box 102, a bearing 504 is embedded in the upper end of the rotating wheel 501, a fixed rod 503 is embedded in the bearing 504, and the fixed rod A sleeve 502 is fixedly installed on the upper end of 503. The sleeve 502 is nested in the surface of the rotating rod 104 and is rotatably connected thereto. When the rotating rod 104 rotates, the inside of the sleeve 502 rotates along with the rotation of the rotating rod 104. The surface of the sleeve 502 is in a stationary state, providing a fixed support force for the fixed rod 503, and the bottom of the fixed rod 503 is embedded in the bearing 1 504. Therefore, when the rotating rod 104 drives the gear 105 to rotate the rod, and then drives the rotating wheel 501 to rotate, the auxiliary rod 5 can rotate in place through the bearing 1 504 and the bearing 2 506, thereby stirring the chemical raw materials in the proportioning box 102.

[0027] In the embodiment of the present invention, blades 505 are provided on the surface of the auxiliary rod 5. When the rotating rod 104 drives the gear 105 to rotate, and then the rotating wheel 501 rotates, the auxiliary rod 5 rotates in place through the action of bearing 1 504 and bearing 2 506. At this time, the blades 505 on the surface of the auxiliary rod 5 rotate together with the auxiliary rod 5 to stir the chemical raw materials in the proportioning box 102. The thrust and shear force generated by the rotational motion of the blades 505 make the chemical raw materials continuously flow and mix in the proportioning box, thereby achieving accurate metering ratio and sufficient stirring effect. Since the blades 505 enhance the stirring effect, the chemical raw materials can reach a uniform proportioning state more quickly, thereby shortening the production cycle and improving production efficiency.

[0028] Working principle: When using the device for metering and proportioning, first inject different chemical liquid raw materials into the feed box 2 through the feed pipe 202. When proportioning is required, open the solenoid valve 3 to allow the chemical liquid to flow from the feed box 2 into the discharge pipe 203. The flow meter 4 measures the flow of the liquid in real time and transmits the data to the control system. The control system adjusts the flow of the liquid according to the preset proportion by controlling the opening of the solenoid valve 3 to achieve accurate metering. The measured chemical liquid flows into the proportioning box 102. At this time, the motor 103 is started, and the motor 103 drives the rotating rod 104 to rotate. When the rotating rod 104 rotates, it drives the gear 105 to rotate, and then drives the rotating wheel 5 01 rotates, and the rotating wheel 501 drives the auxiliary rod 5 to rotate in place through the bearing 1 504 and the bearing 2 506 when rotating, while the sleeve 502 and the fixed rod 503 provide a certain support force for the rotation of the auxiliary rod 5, so that the auxiliary rod 5 is more stable when rotating. When the auxiliary rod 5 rotates, it drives the blades 505 on the surface to rotate, thereby stirring and mixing the chemical raw materials inside the proportioning box 102. The control system adjusts the speed and running time of the motor 103 according to the preset stirring time and intensity to ensure that the chemical liquid is fully mixed and reaches a uniform proportioning state. Then, according to actual needs, the proportioned liquid is transported to the electroplating tank for electroless nickel plating process.
