Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment, and in particular to an edge effect control device. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It is a process that uses electrolysis to attach 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.

[0003] Currently, when steel strips are electroplated in electroplating solutions, the "edge effect" can cause the nickel plating on the edges of the steel strip to be thicker, resulting in an uneven nickel layer across the entire steel strip. Utility Model Content

[0004] The purpose of this invention is to provide an edge effect control device that can effectively avoid edge effects during electroplating of steel strip edges and improve the uniformity of the electroplated layer.

[0005] To solve the above-mentioned technical problems, this utility model provides an edge effect control device, including an electroplating tank filled with electroplating solution, rotating rollers rotatably arranged on both sides of the upper part of the electroplating tank, and a steel strip sequentially wrapped around the outer periphery of the two rotating rollers so that the steel strip between the two rotating rollers hangs down into the electroplating tank. Clamps are arranged opposite each other on both sides of the electroplating tank, and edge barriers are connected to both ends of the clamps. The edge barriers match the side of the vertical section of the steel strip located in the electroplating tank.

[0006] Furthermore, the fixture is provided with a plurality of electroplating anode blocks on its side, and the electroplating anode blocks are in contact with the electroplating solution.

[0007] Furthermore, the edge barrier has a groove on the side facing the steel strip, and the groove matches the edge of the steel strip so that the edge of the steel strip is located inside the groove during electroplating.

[0008] Furthermore, the edge barrier is provided with a plurality of perforated holes along its length, and the perforated holes are disposed through the groove.

[0009] Furthermore, the clamp is connected to a telescopic mechanism on its side so that the telescopic mechanism can adjust the distance between the edge barrier and the side of the steel strip.

[0010] Furthermore, the clamp is detachably connected to the edge barrier.

[0011] The beneficial effects of this invention are as follows: the rotation of the two rollers continuously drives the steel strip to fall into the electroplating tank for nickel plating. During the electroplating process, the clamps on both sides of the electroplating tank simultaneously drive the edge barriers at both ends to move closer to the sides of the steel strip, so that the edge barriers are in contact with the sides of the vertical section of the steel strip in the electroplating tank, effectively suppressing the edge effect, ensuring uniform distribution of the nickel layer, and improving the electroplating quality.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0017] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0018] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0019] like Figures 1-3The present invention provides an edge effect control device, including an electroplating tank 1 containing electroplating solution, rotating rollers 2 rotatably disposed on both sides of the upper part of the electroplating tank 1, and a steel strip 3 sequentially wrapped around the outer periphery of the two rotating rollers 2 so that the steel strip 3 between the two rotating rollers 2 hangs down into the electroplating tank 1. Clamps 4 are arranged opposite to each other on both sides of the electroplating tank 1, and edge barriers 5 are connected to both ends of the clamps 4. The edge barriers 5 match the vertical side of the steel strip 3 located in the electroplating tank.

[0020] The rotation of two rollers continuously drives the steel strip to fall into the electroplating tank for nickel plating. During the electroplating process, the clamps on both sides of the electroplating tank simultaneously move the edge barriers at both ends closer to the sides of the steel strip, so that the edge barriers fit against the sides of the vertical section of the steel strip in the electroplating tank, effectively suppressing the edge effect, ensuring uniform distribution of the nickel layer, and improving the electroplating quality.

[0021] The rotating rollers can be controlled to rotate by a motor or other driving components, and the two rotating rollers rotate in the same direction, so that one roller unwinds the steel strip and the other roller rewinds the steel strip, ensuring the continuous and stable operation of the steel strip.

[0022] In one embodiment of this solution, the steel strip between the two rollers has a U-shaped structure, and the edge barrier is arranged parallel to the two vertical sections of the U-shaped structure. Since the steel strip is continuously conveyed, the bottom of the U-shaped structure will pass through the vertical section during the conveying process, thereby ensuring that the electroplating effect of the steel strip is consistent at each position.

[0023] Preferably, a plurality of electroplating anode blocks 6 are provided on the side of the clamp 4, and the electroplating anode blocks 6 are in contact with the electroplating solution.

[0024] Specifically, by using the electroplating anode block as the electroplating anode and the portion of the steel strip located in the electroplating bath as the electroplating cathode, the electroplating process is stabilized. At the same time, the electroplating anode block is fixed by a fixture to ensure that it maintains a constant distance from the steel strip during the electroplating process, thereby optimizing the electroplating current distribution and further improving the uniformity of nickel layer deposition and electroplating efficiency.

[0025] Preferably, the edge barrier 5 has a groove 7 on the side facing the steel strip 3, and the groove 7 matches the side of the steel strip 3 so that when the steel strip 3 is electroplated, the side of the steel strip 3 is located inside the groove 7.

[0026] Specifically, by setting the groove, the side of the steel strip can be located inside the groove, so that the edge barrier further surrounds the vertical side of the steel strip, improves the uniformity of the electroplating current distribution, and ensures that the electroplating layer on the vertical side of the steel strip is uniform.

[0027] Preferably, the edge barrier 5 is provided with a plurality of hollow holes 8 along its length, and the hollow holes 8 are provided through the groove 7.

[0028] Specifically, the perforated design allows the electroplating solution to flow through the perforations, ensuring that the solution reaches the edges of the steel strip and thus guaranteeing a stable electroplating effect. Simultaneously, the perforated design effectively reduces the deposition of the electroplating solution on the edge barrier, improving the utilization rate of the solution and ensuring the high efficiency and stability of the entire electroplating process.

[0029] Preferably, the clamp 4 is connected to a telescopic mechanism 9 on one side so that the telescopic mechanism 9 can adjust the distance between the edge barrier 5 and the side of the steel strip 3.

[0030] Specifically, the distance between the edge barrier 5 and the steel strip 3 is adapted to steel strips of different widths, ensuring that the edge barrier is always in close contact with the side of the steel strip, with precise adjustment range; improving the stability and consistency of electroplating quality, and avoiding uneven electroplating caused by changes in the width of the steel strip.

[0031] The telescopic mechanism can be a hydraulic telescopic rod.

[0032] Preferably, the clamp 4 and the edge barrier 5 are detachably connected.

[0033] Specifically, when it is necessary to change the size of the edge barrier or perform maintenance, the edge barrier can be quickly removed from the fixture without affecting the fixture itself or the fixing structure of the electroplating anode block, ensuring the simplicity and efficiency of maintenance operations, while ensuring the continuity and stability of the electroplating process.

[0034] In one embodiment of this solution, the clamp and the edge barrier are detachably connected by a bolt and nut structure.

[0035] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
