Description

Technical Field

[0001] This application relates to the field of electroplating technology, and in particular to a nickel plating tank. Background Technology

[0002] Electroplating is a technique that deposits a metal coating on the surface of a substrate material through electrolysis. Nickel plating is one of the most common electroplating processes. It involves placing the workpiece to be plated as the cathode and a nickel plate as the anode in a plating solution containing nickel ions. Under the action of direct current, nickel ions are reduced and deposited on the surface of the workpiece to form a uniform nickel coating, thereby giving the workpiece excellent surface properties.

[0003] There are also some electroplating systems in the prior art. For example, Chinese Patent No. CN221192405U, published on June 21, 2024, discloses an electroplating system including an oil removal tank, a first draining tank, an acid pickling tank, a second draining tank, an electroplating tank, and a third draining tank. In the conveying direction of the electroplated workpiece in the electroplating system, the oil removal tank, the first draining tank, the acid pickling tank, the second draining tank, the electroplating tank, and the third draining tank are arranged sequentially. The conveying path of the electroplated workpiece passes through the interior of the first draining tank, the second draining tank, and the third draining tank, respectively. The interior of the first draining tank, the second draining tank, and the third draining tank are all equipped with multiple air nozzles. The air nozzles in any draining tank are arranged on both sides of the horizontal direction of the conveying path of the electroplated workpiece in that draining tank, and the air nozzles in any draining tank are tilted downwards towards the conveying path of the electroplated workpiece in that draining tank.

[0004] The application describes using multiple air nozzles inside the drain tank to blow away liquid from the electroplated workpiece. However, the inventor believes that because the nozzles are located on the inner wall of the drain tank, in actual operation, the plating rack needs to be passed through the drain tank to ensure that the nozzles can effectively act on the workpiece on the rack and the surrounding liquid, which increases the complexity of the process. Utility Model Content

[0005] This application provides a nickel plating tank with higher liquid blowing efficiency.

[0006] The nickel plating tank provided in this application adopts the following technical solution: A nickel plating tank includes a main body and a gantry frame. The main body has alternating processing pools and drain pools. The drain pools are provided with mounting seats on both sides. Multiple air nozzles are vertically arranged on the mounting seats. The air nozzles are located above the drain pools. The gantry frame is located above the main body and is driven to connect a plating rack. The plating rack is moved above the drain pool by the gantry frame and aligned with the air nozzles.

[0007] Preferably, the gantry includes a support, a longitudinal sliding mechanism, a fixed plate, and a vertical drive motor. The longitudinal sliding mechanism is movably connected to the support along the longitudinal direction, the fixed plate is connected to the longitudinal sliding mechanism, and the drive motor is disposed on the longitudinal sliding mechanism. A groove is formed on the fixed plate, the plating rack is movably connected to the groove along the longitudinal direction, and the drive motor is driven to the top of the plating rack to drive the plating rack to move longitudinally.

[0008] Preferably, the plating rack includes a sliding plate and multiple frames, the multiple frames are mounted on the sliding plate and are evenly distributed in the transverse direction, the top of the sliding plate is provided with multiple rotating motors, the multiple rotating motors are connected one-to-one to the frames to drive the frames to rotate, and the frames are provided with four sets of hooks distributed at 90° intervals.

[0009] Preferably, the bottom end of the fixing plate is located below the bottom end of the frame and on the rear side of the frame.

[0010] Preferably, the drain opening is movably connected to a protective mesh plate.

[0011] In summary, this application includes at least one of the following beneficial technical effects: 1. By placing the air nozzle above the drain tank, the liquid blowing process does not require additional driving of the plating rack into the drain tank, simplifying the liquid blowing steps, saving time in the liquid blowing process, and thus improving the efficiency of nickel plating.

[0012] 2. By setting up a rotating motor, the frame can be driven to rotate and cooperate with the air nozzle. The frame can rotate while blowing liquid, so that the product on the hook, which was originally in a position that was not easily exposed to wind, can be exposed to wind through rotation, thus improving the efficiency of blowing liquid.

[0013] 3. By setting up a fixing plate, the fixing plate can not only guide the slide plate, but also act as a stop to prevent liquid from splashing into the adjacent reaction tank, thus ensuring the reaction effect of the next reaction tank. Attached Figure Description

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] This application provides a nickel plating tank, such as Figures 1 to 4 As shown, it includes a main body 1 and a gantry frame 2. The main body 1 is a steel structure laid on the ground. Processing pools 11 and draining pools 12 are arranged alternately along the longitudinal direction on the main body 1. The longitudinal direction is the conveying direction of the products in the nickel plating process. Different processing pools 11 contain different processing solutions required for nickel plating, such as alkaline degreasing solution, acidic degreasing solution or organic solvent for degreasing, hydrochloric acid or sulfuric acid solution for rust removal, and nickel ion-containing solution for electroplating. The above are commonly used processing solutions in the nickel plating process in the prior art, which will not be described in detail here.

[0021] like Figure 1 and Figure 3 As shown, the treatment tank 11 has V-shaped grooves formed on both sides of the transverse direction. The V-shaped grooves are used to place the gantry frame 2. The drain tank 12 is set between two adjacent treatment tanks 11 and is used to receive the residual liquid dripping from the product after it has been soaked in the previous treatment tank 11. The opening of the drain tank 12 is movably connected to a protective grid plate 6. Specifically, the opening of the drain tank 12 has a stepped structure. The protective grid plate 6 is set on the stepped structure and can be removed when needed. The protective grid plate 6 is used to prevent falling products from falling into the drain tank 12.

[0022] like Figure 1 and Figure 4 As shown, the gantry 2 includes a support 21, a longitudinal sliding mechanism 22, a fixing plate 23, and a vertical drive motor 24. The support 21 is fixed on both sides of the main body 1, and the longitudinal sliding mechanism 22 is movably connected to the support 21 along the longitudinal direction and is located above the main body 1. like Figures 1 to 4As shown, the fixed plate 23 is connected to the longitudinal sliding mechanism 22. A groove is formed on the fixed plate 23, and a plating rack 5 is movably connected in the groove. The plating rack 5 is used to hang products. The drive motor is set on the longitudinal sliding mechanism 22 and is connected to the top of the plating rack 5. It is used to drive the plating rack 5 to move longitudinally, so that the products hanging on the plating rack 5 move down to enter the processing tank 11, and move up after processing. The longitudinal sliding mechanism 22 drives the plating rack 5 to move longitudinally above the drain tank 12. The specific structure of the bracket 21 and the longitudinal sliding mechanism 22 is a common structure of the gantry 2 in the nickel plating process in the prior art, and will not be described in detail here.

[0023] Specifically, the plating rack 5 includes a slide plate 51 and multiple frames 52. The multiple frames 52 are mounted on the slide plate 51 and are evenly distributed laterally. Multiple rotating motors 53 are installed on the top of the slide plate 51. The multiple rotating motors 53 are connected one-to-one to the frames 52 to drive the frames 52 to rotate. Four sets of hooks 54 are installed on the frames 52 at 90° intervals. The rotating motors 53 drive the frames 52 to rotate, which in turn drives the hooks 54 to rotate. The fixing plate 23 is located on the rear side of the frames 52, and its bottom end is located below the bottom end of the frames 52. This can prevent residual liquid from splashing into the treatment tank 11 behind the product during the draining process, thus affecting the treatment effect of the liquid in the treatment tank 11.

[0024] like Figure 1 and Figure 2 As shown, mounting bases 3 are provided on both sides of the drain pool 12. The mounting bases 3 can be made of stainless steel. Multiple air nozzles 4 are vertically arranged on the upper edge of the mounting base 3. The air nozzles 4 on both sides face each other and are located above the drain pool 12. They are used to blow the residual liquid on the product into the drain pool 12.

[0025] The specific working process of a nickel plating tank according to this application includes: the longitudinal sliding mechanism 22 drives the plating rack 5 to move longitudinally, and through the drive motor, it is sequentially inserted into different treatment tanks 11. After immersion in each reaction tank, the longitudinal sliding mechanism 22 and the drive motor cooperate to stop the plating rack 5 above the adjacent drain tank 12. The air nozzle 4 is activated to blow the residual liquid off the product. At the same time, the rotating motor 53 drives the frame 52 to rotate so that the product on each hook 54 can be exposed to the air to improve the blowing efficiency. The fixing plate 23 can prevent the residual liquid blown off from flying into the adjacent reaction tank.

[0026] Compared with the prior art, the liquid blowing step of the nickel plating tank of this application does not require additional driving of the plating rack 5 into the drain tank 12, which simplifies the liquid blowing step. The cooperation between the rotating motor 53 and the air nozzles 4 on both sides improves the liquid blowing efficiency. The fixing plate 23 not only provides guidance for the slide plate 51, but also acts as a stop to prevent liquid from splashing into the adjacent reaction tank, thus ensuring the reaction effect of the next reaction tank.

[0027] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
