[0001] This utility model belongs to the field of electroplating technology, specifically relating to a conveying device for multi-layer gradient nickel-gold electroplating. Background Technology
[0002] Nickel-gold is an alloy composed of nickel and other metals such as copper, silver, and zinc. Gold is the elemental form of the chemical element gold; it is a soft, golden-yellow, corrosion-resistant precious metal. The nickel content in nickel-gold is not fixed but depends on the specific alloy type, the intended use of the product, and relevant manufacturing standards.
[0003] In nickel-gold electroplating of materials, multiple layers are often applied to the outer surface to extend the lifespan of the plating. Currently, due to the varying elemental content of the plating layers, multiple plating tanks are needed for multi-gradient plating. This process typically requires manual feeding of materials into each tank sequentially for individual plating, which introduces delays and wastes time, resulting in low plating efficiency. Therefore, this application proposes a conveying device for multi-gradient nickel-gold electroplating. Utility Model Content
[0004] The purpose of this invention is to provide a conveying device for multi-layer gradient nickel-gold electroplating, in order to solve the problem mentioned in the background art that when processing multi-layer nickel-gold electroplating, it is necessary to manually feed the material into multiple electroplating tanks in sequence. However, manual handling has a certain lag, which will cause some waste of time and result in low efficiency of material electroplating.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveying device for multi-layer gradient nickel-gold electroplating, comprising a base plate, a support, a crawler conveyor, and an electroplating device. The support is mounted on the base plate, and the crawler conveyor is mounted on the support. The crawler conveyor includes several crawler plates, and mounting seats are provided on the crawler plates. Vertical pipes are provided on the mounting seats, and lifting plates that can move vertically relative to the vertical pipes are inserted into the vertical pipes.
[0006] The bottom of the lifting plate is provided with a support frame, and hooks are installed at the bottom of the support frame;
[0007] The upper side of the base plate is provided with a guide rail, and the support frame is provided with a lifting rod that cooperates with the guide rail. The guide rail includes an electroplating rail and a connecting rail.
[0008] The electroplating track includes a falling area, a horizontal area, and an upward area. The base plate is provided with a first electroplating box and a second electroplating box. Multiple electroplating tracks are provided.
[0009] In a further technical solution, the vertical pipe is provided with a vertical groove and an auxiliary groove.
[0010] In a further technical solution, two auxiliary grooves are provided, with the vertical groove located in the middle of the vertical pipe, and the two auxiliary grooves respectively located on both sides of the vertical groove, and both auxiliary grooves are connected to the vertical groove.
[0011] In a further technical solution, two guide blocks are installed on the top of the lifting plate, and the two guide blocks cooperate with two auxiliary slots respectively.
[0012] In a further technical solution, a spring is provided inside the vertical groove, with one end of the spring connected to the inner wall of the vertical groove and the other end of the spring connected to the lifting plate.

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0028] like Figures 1-5 As shown in the figure, the multi-layer gradient nickel-gold electroplating conveying device provided by this utility model includes a base plate 1, a support 2, a crawler conveyor 3, and an electroplating device. The support 2 is set on the base plate 1, and the crawler conveyor 3 is set on the support 2. The crawler conveyor 3 includes a plurality of crawler plates 4. The crawler conveyor 3 can drive the crawler plates 4 to rotate, so as to achieve the effect of transporting materials.
[0029] In order to transport the raw materials that need to be electroplated, mounting seats 5 are provided on the track plates 4. The mounting seats 5 need to be spaced several track plates 4 apart. This is to avoid the materials hanging at the bottom from colliding with each other. There can be four or multiples of four mounting seats 5. A vertical tube 6 is provided on the mounting seat 5. A lifting plate 7 that can move up and down relative to the vertical tube 6 is inserted into the vertical tube 6.
[0030] Specifically, the vertical tube 6 is provided with a vertical groove 601 and auxiliary grooves 602. There are two auxiliary grooves 602, and the vertical groove 601 is located in the middle of the vertical tube 6. The two auxiliary grooves 602 are respectively located on both sides of the vertical groove 601, and both auxiliary grooves 602 are connected to the vertical groove 601. Two guide blocks are installed on the top of the lifting plate 7, and the two guide blocks cooperate with the two auxiliary grooves 602 respectively. The lifting plate 7 cooperates with the vertical groove 601, and the lifting plate 7 and the vertical groove 601 can only slide relative to each other up and down. With the help of the two guide blocks on the top of the lifting plate 7, the remaining movement of the lifting plate 7 can be guided, thus making the up and down movement of the lifting plate 7 smoother.
[0031] More specifically, a spring 8 is installed inside the vertical groove 601. One end of the spring 8 is connected to the inner wall of the vertical groove 601, and the other end of the spring 8 is connected to the lifting plate 7. The spring 8 is positioned at the junction of the lifting plate 7 and the vertical groove 601.
[0032] In order to suspend the materials to be electroplated, a support frame 9 is provided at the bottom of the lifting plate 7, and a hook 11 is installed at the bottom of the support frame 9 to suspend the materials to be electroplated.
[0033] To allow materials suspended on hook 11 to enter the electroplating tank, a guide rail 16 is provided on the upper side of the base plate 1, and a lifting rod 10 is provided on the support frame 9. The lifting rod 10 cooperates with the guide rail 16. The guide rail 16 includes electroplating rails 1601 and connecting rails 1602. Multiple electroplating rails 1601 are connected by connecting rails 1602. (See reference...) Figure 1 The guide rail 16 is set around the crawler conveyor 3. The electroplating rail 1601 in a local area allows the lifting plate 7 and lifting rod 10 to fall and rise, allowing the suspended material to be immersed in the electroplating solution in the electroplating tank. The weight of the material is mostly supported by the guide rail 16 and lifting rod 10. The crawler conveyor 3 has a relatively small pulling force and is not prone to deformation due to excessive material weight. However, it is still not suitable for electroplating heavy materials, as this could easily damage the guide rail 16.
[0034] Specifically, the electroplating track 1601 includes a falling area, a horizontal area, and an upward area. The falling area is inclined downwards and smoothly connected to the side connecting track 1602. The upward area is also smoothly connected to the side connecting track 1602. The two ends of the horizontal area are smoothly connected to the falling area and the upward area, respectively. In this way, the entire lifting rod 10 falls, moves horizontally, and rises along the electroplating track 1601.
[0035] The lifting rod 10 moves along the guide rail 16. When it reaches the electroplating rail 1601, it first moves down along the falling area and then enters the horizontal area. In the horizontal area, the material is completely immersed in the electroplating solution in the electroplating tank. The electroplating device starts and electroplats a layer of nickel-gold on the surface of the material. Then, the crawler conveyor 3 drives the mounting base 5 and other components to continue moving, pushing the material into the lifting area. In this area, the material is gradually pulled out of the electroplating solution. Finally, the material is removed from the electroplating tank. By setting up multiple electroplating rails 1601 and multiple electroplating tanks, the material can be electroplated in sequence. The electroplating process is integrated into one, eliminating the need for transfer between multiple devices, which saves transfer time and improves efficiency. Moreover, multiple electroplating tanks can perform their respective electroplating steps simultaneously. In this way, when electroplating large quantities of material, the electroplating time of each step can overlap to a certain extent, reducing time loss and increasing output.
[0036] In order to improve the plating effect, nickel-gold electroplating is mostly carried out by multi-layer electroplating. The electroplating process includes the following steps: First, a layer of pure copper with a nickel content of 0% is electroplated on the outer surface of the workpiece.
[0037] Next, a layer of low-nickel gold with a nickel content of 5-8% is electroplated onto the surface of the pure copper plating.
[0038] Next, a layer of medium-nickel gold with a Sn content of 10-13% is electroplated onto the surface of the low-nickel gold plating.
[0039] Finally, a layer of high-nickel gold with a Sn content of 14-20% is electroplated onto the surface of the medium-nickel gold plating.
[0040] In order to perform multi-gradient nickel-gold electroplating on the material, a first electroplating box 12 and a second electroplating box 13 are set on the base plate 1, and multiple electroplating tracks 1601 are set, including a third electroplating box 14 and a fourth electroplating box 15. Some factories use a two-step electroplating method to save costs, so the electroplating boxes can also be set according to actual needs. When there are four electroplating boxes, there are four electroplating tracks 1601, which are located at the first electroplating box 12, the second electroplating box 13, the third electroplating box 14, and the fourth electroplating box 15, respectively.
[0041] In summary, this utility model embodiment provides a multi-layer gradient nickel-gold electroplating conveying device. The lifting rod 10 moves along the guide rail 16. When it reaches the electroplating rail 1601, it first moves down along the falling area and then enters the horizontal area. In the horizontal area, the material is completely immersed in the electroplating solution in the electroplating tank. The electroplating device starts and electroplats a layer of nickel-gold on the surface of the material. Then, the crawler conveyor 3 drives the mounting base 5 and other components to continue moving, pushing the material into the lifting area. In this area, the material is gradually pulled out of the electroplating solution. Finally, the material is removed from the electroplating tank. By setting up multiple electroplating rails 1601 and multiple electroplating tanks, the material can be electroplated in sequence. The electroplating process is integrated into one, eliminating the need for transfer between multiple devices, saving transfer time and improving efficiency. Moreover, multiple electroplating tanks can perform their respective electroplating steps simultaneously. In this way, when electroplating large quantities of material, the electroplating time of each step can overlap to a certain extent, reducing time loss and increasing output.
[0042] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
