Description

Technical Field

[0001] This utility model specifically relates to a circumferential anode titanium basket and a carbon fiber metal electrodeposition device, belonging to the field of electrodeposition technology. Background Technology

[0002] Carbon fiber metallization involves coating the surface of carbon fibers with a uniform thickness of metal or alloy. The main reaction apparatus is an electrodeposition tank, including conductive cathode rollers and anode titanium baskets. The carbon fiber is in contact with the cathode rollers at both ends of the electrodeposition tank, providing electrical conductivity. The portion of the carbon fiber immersed in the plating solution serves as the workpiece to be plated. The soluble metal to be plated, filled within the titanium basket, acts as the anode. Under energized conditions, precipitated cations enter the plating solution and move towards the carbon fiber bundle. The metal cations gain electrons on the carbon fiber surface, are reduced to metal particles, and deposit to form the coating.

[0003] Traditional anode titanium baskets are rectangular frames placed at the bottom of the electrodeposition tank, with carbon fibers suspended directly above the basket and submerged near the surface of the plating solution. Due to the relative positions of the carbon fibers and the basket, the electric field lines are unevenly distributed; they are denser below the carbon fiber bundle and denser above the basket. The lower part of the carbon fiber bundle accumulates more electrons, resulting in a stronger cation absorption capacity and a thicker coating. Conversely, the upper part has sparser electric field lines, fewer electrons, and a weaker cation absorption capacity, resulting in a thinner coating. This leads to uneven coating thickness and black cores within the carbon fiber bundle. Furthermore, the denser electric field lines above the basket cause the metal to dissolve quickly. The anolyte produced by the dissolution of the upper metal covers the surface of the undissolved metal below, affecting cation deposition, reducing current efficiency, and wasting the metal to be plated. Utility Model Content

[0004] The main objective of this invention is to provide a circumferential titanium anode basket and a carbon fiber metal electrodeposition device. The main body of the titanium basket is an annular tubular frame with a titanium screen fixed on its surface. The cavities between the screens are filled with soluble anode metal. Current is transmitted to the metal to be plated through the titanium basket screen. The carbon fiber moves at a constant speed near the axis of the titanium basket, and the distance between the carbon fiber and each point on the titanium basket is approximately equal, forming uniformly diverging electric field lines. The anode metal loses electrons and releases cations into the plating solution, which are uniformly distributed around the carbon fiber bundles. Under the action of the electric field, the cations move towards the surface of the carbon fiber and gain electrons to complete the metal electrodeposition, resulting in a coating of uniform thickness, thereby overcoming the shortcomings of the prior art.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model includes:

[0006] The first aspect of this utility model provides a circumferential anode titanium basket, which includes: a conductive support frame and a titanium basket body, wherein the titanium basket body is a circular cylindrical structure, and the conductive support frame is fixed and electrically connected to the titanium basket body;

[0008] The central region of the titanium basket body has a cavity structure with open ends formed by its own overall enclosure. Furthermore, the titanium basket body is provided with a slit that directly communicates with the cavity structure. The slit allows carbon fibers to enter and exit the cavity structure radially along the titanium basket body, and the cavity structure allows carbon fibers to pass continuously along their own axial direction.

[0014] Compared with the prior art, the advantages of this utility model include:

[0015] This utility model provides a carbon fiber metal electrodeposition device, which innovates the design of the carbon fiber metallization anode device by proposing an annular anode titanium basket. The anode titanium basket has an annular barrel-shaped structure. The carbon fiber moves near the axis of the annular anode titanium basket. Under the condition of energization, electric field lines are uniformly distributed from far to near the carbon fiber bundle as the center. The cations are uniformly distributed around the carbon fiber under the action of the electric field force, so that the electron distribution on each filament in the carbon fiber bundle is uniform and the cation attraction ability is equal. Each carbon fiber can obtain a metal coating of uniform thickness, which solves the problems of uneven metal coating and black core of carbon fiber. At the same time, the optimized distribution of electric field lines also improves the tip discharge effect of carbon fiber and reduces the problem of fuzz on the fiber surface after metal deposition.

[0043] Specifically, the structures of the pay-off roller assembly 100, pretreatment assembly 200, posttreatment assembly 400 and take-up roller assembly 500 in this application are all known in the art and are not considered improvements to the present invention. Therefore, only a simple overview and description of their structures are given below.

[0044] Specifically, the pay-off roller assembly 100 is used to pay off one or more rolls of carbon fiber, and the take-up roller assembly 500 is used to take up one or more rolls of carbon fiber. As known to those skilled in the art, the pay-off roller assembly 100 generally includes one or more freely rotatable pay-off rollers, which are used to fix the carbon fiber rolls, and the carbon fiber rolls can rotate together with the pay-off rollers. Preferably, the pay-off roller assembly 100 may also include a speed adjustment mechanism for adjusting the speed of the pay-off rollers, etc., and by adjusting the speed of the pay-off rollers, the tension and pay-off rate of the carbon fiber during travel can be adjusted.

[0045] Specifically, the pretreatment component 200 is used to remove the sizing agent from the surface of the carbon fibers and / or to clean the carbon fibers, i.e., the aforementioned pretreatment. For example, the pretreatment component 200 may include a high-temperature treatment chamber, a pre-impregnation tank, and / or a spraying mechanism, etc., whereby the high-temperature treatment chamber is used to remove the sizing agent from the surface of the carbon fibers, and the pre-impregnation tank and / or the spraying mechanism is used to clean the carbon fibers. Specifically, the post-treatment component 400 is used to clean and dry the carbon fibers after metal electrodeposition treatment. Specifically, the post-treatment component 400 may include a washing mechanism and an oven, etc.

[0046] Please refer to the following: Figure 1 , Figure 2 The electrodeposition reaction assembly 300 includes an electrodeposition reaction tank 310, two cathode rollers 320, four guide rollers 330, an anode titanium basket 340, and a power supply. The two cathode rollers 320 are arranged on both sides of the electrodeposition reaction tank 310 along a first direction. The anode titanium basket 340 is arranged inside the electrodeposition reaction tank 310. The four guide rollers 330 are spaced apart on both sides of the anode titanium basket 340 along the first direction, with two on each side. The two cathode rollers 320 and the four guide rollers 330 together restrict the movement of the carbon fiber in the electrodeposition reaction tank 310 and allow the carbon fiber to pass through the anode titanium basket 340 along the axial direction within the electrodeposition reaction tank 310, especially allowing the carbon fiber to pass through the central region of the anode titanium basket 340. At the same time, the four guide rollers 330 can also adjust the tension of the carbon fiber.

[0047] Please refer to the following for details. Figure 1 and Figure 2 The cathode roller 320 is made entirely of conductive material. Its end is connected to the negative terminal of the power supply, and its surface is in close contact with the carbon fiber, which then absorbs electrons and acts as the cathode. Specifically, the cathode roller 320 can rotate around its own axis to reduce wear between the cathode roller 320 and the carbon fiber. More specifically, to ensure that the carbon fiber and the surface of the cathode roller 320 remain in contact, a limiting rod 350 is correspondingly provided above each cathode roller 320. The limiting rod 350 is arranged parallel to the cathode roller 320 and is used to compress the carbon fiber, keeping it in contact with the roller surface of the cathode roller 320. To reduce wear on the carbon fiber caused by the limiting rod 350, it is designed to rotate around its own axis. For example, the limiting rod 350 can be a sponge rod, etc.

[0048] Specifically, the guide roller 330 is made of insulating, corrosion-resistant, and high-temperature-resistant material. Its shaft is equipped with a bearing, allowing it to rotate passively to reduce contact friction with the carbon fiber and improve the surface fuzziness of the carbon fiber. After passing through multiple conductive rollers 330, the carbon fiber reverses its direction of travel and is completely immersed in the electroplating mother liquor within the electrodeposition reaction tank 310. The surface and interior of the carbon fiber are in full contact with the electroplating mother liquor. The compression by the guide rollers 330 and the immersion in the solution allow air bubbles on the carbon fiber surface to detach promptly, reducing the porosity of the coating and improving the corrosion resistance of the metal composite fiber.

The metal cations in the electroplating mother liquor are uniformly distributed around the carbon fiber monofilaments under the action of the electric field, gaining electrons from the surface of each carbon fiber to complete the metal electrodeposition on the carbon fiber surface.

[0050] Specifically, the interior of the titanium basket body 342 has a receiving cavity for accommodating the anode metal material. The surface of the titanium basket body 342 is also provided with an anode metal material filling port 3423 and multiple perforated structures. The anode metal material filling port and the perforated structures are all connected to the receiving cavity inside the basket body. The central region of the titanium basket body 342 has a perforated structure 3421 formed by the entire body and open at both ends. Furthermore, a slit 3422 is provided on the titanium basket body 342, which directly communicates with the perforated structure 3421. The slit 3422 allows carbon fibers to enter and exit the perforated structure 3421 along the radial direction of the titanium basket body 342, and the perforated structure 3421 allows carbon fibers to pass continuously along its own axial direction. The multiple perforated structures are distributed on multiple concentric circumferences or multiple coaxial cylindrical surfaces. The centers of the multiple circumferences are located on the axis of the titanium basket body 342, or the multiple cylindrical surfaces are coaxial with the titanium basket body 342. For example, the slit has a circumferential width of 1cm to 2cm, and the receiving cavity has a radial width of 3cm to 5cm.

[0051] In a typical implementation, the titanium basket body 342 can be a one-piece structure. More specifically, the titanium basket body 342 has an inner ring surface, an outer ring surface, a first end face, a second end face, a first side face, and a second side face. The outer ring surface surrounds the outer periphery of the inner ring surface. The first end face and the second end face are located at both ends of the titanium basket body 342 along the axial direction of the titanium basket body 342. The first side face and the second side face are spaced apart along the circumference of the titanium basket. The gap 3422 is located between the first side face and the second side face. The first side face and the second side face are closed structures. The perforated structures are distributed on the inner ring surface, the outer ring surface, the first end face, and the second end face. The multiple perforated structures located on the same circumference or the same cylindrical surface have the same shape and size.

[0052] In another typical implementation, the titanium basket body 342 includes a non-closed inner ring screen, a non-closed outer ring screen, a first end face screen, a second end face screen, a first side plate, and a second side plate. The outer ring screen is arranged around the periphery of the inner ring screen. The first end face screen and the second end face screen are located at both ends of the inner ring screen and the outer ring screen along the axial direction of the inner ring screen, and are fixedly connected to the inner ring screen and the outer ring screen. The first side plate and the second side plate are respectively fixedly connected to the inner ring screen, the outer ring screen, the first end face screen, and the second end face screen. The first side plate and the second side plate are arranged along the inner ring screen. The mesh is circumferentially spaced, and the inner ring screen, the outer ring screen, the first end face screen, the second end face screen, the first side plate, and the second side plate enclose and form a circular receiving cavity.
