Abstract
Description
Technical Field
[0001] This utility model relates to an anode titanium mesh arrangement structure, specifically to a cross arrangement structure of anode titanium mesh in a copper cylinder and its horizontal coating lines. Background Technology
[0002] Currently, horizontal coating lines are typically designed with eight copper tanks to complete the thickening of a 1μm copper layer. The copper tanks are divided into a pre-plating area and a copper plating area. Copper tanks one to three are the pre-plating area, which is the base plating stage and lays a good foundation for thickening the copper plating. Copper tanks four to eight are the copper plating thickening area.
[0003] like Figure 1 As shown, the anode titanium mesh 100 is arranged symmetrically from top to bottom. The coating passes through the middle of the upper and lower anode titanium mesh 100. The copper plating solution is drawn up from the bottom of the copper tank, and the immersion height is about 1 to 2 cm higher than the upper anode titanium mesh. The anode of each copper tank is made of multiple titanium meshes spliced together, which facilitates the adjustment of local current. The edge of the coating is connected to the negative terminal of the rectifier with a continuous conductive clamp 200 to form a power circuit.
[0004] In the traditional method, the anode titanium mesh is usually centered in the copper bath of the pre-plating zone. However, since the pre-plating zones one to three of the copper bath are the base plating stage, the output current is small and the plating layer is very thin. The anode titanium mesh being centered in the copper bath can easily cause gaps on both sides of the bath, resulting in uneven pre-plating thickness. After winding, the appearance will show deformation, which will ultimately affect the final coating.
[0005] Therefore, a cross-arrangement structure of anode titanium mesh in a copper cylinder and its horizontal coating lines were designed to solve the above problems.
[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content
[0007] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a cross-arrangement structure of anode titanium mesh in a copper cylinder.
[0008] To achieve the above and other related objectives, the technical solution provided by this utility model is: a cross-arrangement structure of anode titanium mesh within a copper tank, used in a pre-plating zone copper tank. The pre-plating zone copper tank consists of a first section, a second section, a third section, and a fourth section. Each of the first, second, third, and fourth sections contains an anode titanium mesh splicing structure, and these anode titanium mesh splicing structures are arranged in a cross-arrangement. In this solution, the cross-arrangement of the anode titanium mesh splicing structures within the pre-plating zone copper tank reduces gaps on both sides of the tank, resulting in a more uniform current distribution.
[0009] Furthermore, the anode titanium mesh splicing structure in the first section of the copper tank is arranged close to the operating side of the pre-plating area copper tank; the anode titanium mesh splicing structure in the second section of the copper tank is arranged close to the maintenance side of the pre-plating area copper tank; the anode titanium mesh splicing structure in the third section of the copper tank is arranged close to the operating side of the pre-plating area copper tank; and the anode titanium mesh splicing structure in the fourth section of the copper tank is arranged close to the maintenance side of the pre-plating area copper tank. In this design, compared to the traditional central arrangement, setting the anode titanium mesh splicing structure to be cross-displaced towards the operating and maintenance sides of the copper tank allows for a more uniform current distribution, ensuring a uniform pre-plating layer thickness.
[0010] Furthermore, the distance between the anode titanium mesh splicing structure in the first section of the copper cylinder and the maintenance side of the pre-plating zone copper cylinder is greater than the distance between the anode titanium mesh splicing structure in the second section of the copper cylinder and the maintenance side of the pre-plating zone copper cylinder; the distance between the anode titanium mesh splicing structure in the third section of the copper cylinder and the maintenance side of the pre-plating zone copper cylinder is greater than the distance between the anode titanium mesh splicing structure in the fourth section of the copper cylinder and the maintenance side of the pre-plating zone copper cylinder. In this scheme, the arrangement of each anode titanium mesh splicing structure 5 relative to the same side of the pre-plating zone copper cylinder is cross-arranged, resulting in a more uniform current distribution and a more uniform pre-plating layer thickness.
[0011] Furthermore, each of the aforementioned anode titanium mesh splicing structures is composed of six anode titanium mesh units symmetrically spliced together. In this design, symmetrically splicing the anode titanium mesh units makes the anode titanium mesh splicing structure more stable.
[0012] Furthermore, the anode titanium mesh unit is trapezoidal in shape. In this design, the trapezoidal anode titanium mesh unit is easy to assemble and has a strong load-bearing capacity.
[0013] Furthermore, the anode titanium mesh unit includes a titanium mesh body, titanium plates, and positive electrode connection points. Several titanium plates are disposed on the titanium mesh body, and each titanium plate has several welding points. In this design, the titanium plates and welding points on the titanium mesh body facilitate welding; the positive electrode connection points facilitate wiring; and the production efficiency of the anode titanium mesh unit is improved.
[0014] Furthermore, the welding points are evenly distributed on the titanium plate. In this design, the even distribution of welding points on the titanium plate ensures the stability of the welded structure.
[0015] Furthermore, each of the anode titanium mesh units has one positive terminal connection point. In this design, providing one positive terminal connection point ensures concentrated and stable current output.
[0016] This utility model also discloses a horizontal coating line, including a pre-plating zone copper tank and a copper plating zone copper tank, wherein the pre-plating zone copper tank includes a cross-arrangement structure of anode titanium mesh in the copper tank as described in any of the above embodiments.
[0017] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:
[0018] The cross-arrangement structure of the anode titanium mesh in the copper cylinder designed in this utility model has a simple arrangement method, only requiring spatial displacement without the need to change the core components. The displacement size is flexibly adjustable. Compared with the traditional anode titanium mesh centrally distributed structure, it reduces the gaps on both sides of the copper cylinder, making the current distribution more uniform, thereby making the pre-plating layer thickness more uniform and preventing it from affecting the final coating. It can also improve the appearance and prevent deformation after winding. Attached Figure Description

[0029] Example 1: See Figure 4As shown, this embodiment provides a cross-arrangement structure of anode titanium mesh in a copper tank for use in the pre-plating zone copper tank. The pre-plating zone copper tank consists of a first copper tank 1, a second copper tank 2, a third copper tank 3, and a fourth copper tank 4. Each of the first copper tank 1, the second copper tank 2, the third copper tank 3, and the fourth copper tank 4 is provided with an anode titanium mesh splicing structure 5. The anode titanium mesh splicing structures 5 in the first copper tank 1, the second copper tank 2, the third copper tank 3, and the fourth copper tank 4 are arranged cross-arranged with each other.
[0030] In the cross arrangement, only spatial displacement is required, and the core components do not need to be changed. The displacement size is flexibly adjustable.
[0031] In this embodiment, the anode titanium mesh splicing structure 5 in the copper cylinder of the pre-plating zone is arranged in a cross pattern, which can reduce the gaps on both sides of the cylinder edge and make the current distribution more uniform.
[0032] Example 2: See Figure 4 As shown, this embodiment is a further improvement based on Embodiment 1.

[0033] The arrangement near the operating side and the arrangement near the maintenance side can be interchanged.
[0034] Specifically, the anode titanium mesh splicing structure 5 in the first copper tank 1 is shifted 150mm from its central position within the tank towards the operating side of the pre-plating zone copper tank; the anode titanium mesh splicing structure 5 in the second copper tank 2 is shifted 150mm from its central position within the tank towards the maintenance side of the pre-plating zone copper tank; the anode titanium mesh splicing structure 5 in the third copper tank 3 is shifted 150mm from its central position within the tank towards the operating side of the pre-plating zone copper tank; and the anode titanium mesh splicing structure 5 in the fourth copper tank 4 is shifted 150mm from its central position within the tank towards the maintenance side of the pre-plating zone copper tank.
[0035] The offset distance of the anode titanium mesh splicing structure 5 relative to the center position inside the cylinder is not limited to 150mm. It can be adjusted according to the specific plan in the implementation process to reduce the gaps on both sides of the cylinder and make the current distribution uniform.
[0036] In this embodiment, compared with the traditional centered arrangement, the anode titanium mesh splicing structure 5 is set to be cross-displaced towards the operating side and maintenance side of the copper cylinder, which can make the current distribution more uniform and ensure the uniform thickness of the pre-plating layer.
[0037] Example 3: See Figure 4 As shown, this embodiment is a further improvement based on embodiment two. Specifically, the distance between the anode titanium mesh splicing structure 5 in the first copper cylinder 1 and the maintenance side of the pre-plating area copper cylinder is greater than the distance between the anode titanium mesh splicing structure 5 in the second copper cylinder 2 and the maintenance side of the pre-plating area copper cylinder; the distance between the anode titanium mesh splicing structure 5 in the third copper cylinder 3 and the maintenance side of the pre-plating area copper cylinder is greater than the distance between the anode titanium mesh splicing structure 5 in the fourth copper cylinder 4 and the maintenance side of the pre-plating area copper cylinder.
[0038] In this embodiment, the arrangement of each anode titanium mesh splicing structure 5 relative to the same side of the pre-plating zone copper cylinder is cross-shaped, which makes the current distribution more uniform and the pre-plating layer thickness more uniform.
[0039] Example 4: See Figure 3 As shown, this embodiment is a further improvement based on embodiment three. Specifically, the anode titanium mesh splicing structure 5 is composed of six anode titanium mesh units 6 symmetrically spliced together.
[0040] In this embodiment, symmetrical splicing of the anode titanium mesh units 6 can make the anode titanium mesh splicing structure 5 more stable.
[0041] Example 5: See Figure 2 As shown, this embodiment is a further improvement based on embodiment four, specifically in that the shape of the anode titanium mesh unit 6 is trapezoidal.
[0042] In this embodiment, the trapezoidal anode titanium mesh unit 6 is easy to assemble and has a strong load-bearing capacity.
[0043] Example 6: See Figure 2 As shown, this embodiment is a further improvement based on embodiment five. Specifically, the anode titanium mesh unit 6 includes a titanium mesh body 601, a titanium plate 602, and a positive electrode connection point 603. There are several titanium plates 602, all of which are disposed on the titanium mesh body 601. Several welding points 604 are provided on the titanium plates 602.
[0044] Current transmission phenomenon: Current flows from the positive terminal of the rectifier through the wire to the positive terminal of the anode titanium mesh, and then through the welding point 604 between the titanium plate 602 and the titanium mesh, distributing throughout the titanium mesh. Among them, the positive terminal connection point 603 is a high current region.
[0045] In this embodiment, a titanium plate 602 and a welding point 604 are provided on the titanium mesh body 601 to facilitate welding; a positive electrode connection point 603 is provided to facilitate wiring; and the production efficiency of the anode titanium mesh unit 6 is improved.
[0046] Example 7: See Figure 2As shown, this embodiment is a further improvement based on embodiment six. Specifically, the welding points 604 are evenly distributed on the titanium plate 602.
[0047] In this embodiment, the welding points 604 are evenly distributed on the titanium plate 602, which can ensure the stability of the welded structure.
[0048] Example 8: See Figure 2 As shown, this embodiment is a further improvement based on embodiment seven. Specifically, each anode titanium mesh unit 6 has one positive terminal connection point 603.
[0049] In this embodiment, a positive terminal 603 is provided to make the current output concentrated and stable.
[0050] A horizontal coating line includes a pre-plating zone copper tank and a copper plating zone copper tank, wherein the pre-plating zone copper tank includes any one of the above eight embodiments.
[0051] The cross-arrangement structure of the anode titanium mesh in the copper cylinder designed in this utility model has a simple arrangement method, only requiring spatial displacement without the need to change the core components. The displacement size is flexibly adjustable. Compared with the traditional anode titanium mesh centrally distributed structure, it reduces the gaps on both sides of the copper cylinder, making the current distribution more uniform, thereby making the pre-plating layer thickness more uniform and preventing it from affecting the final coating. It can also improve the appearance and prevent deformation after winding.
