Description

Technical Field

[0001] This invention relates to the field of aluminum wire anodizing technology, specifically to an anodizing equipment and process for aluminum wire. Background Technology

[0002] Anodizing is a key process for generating a protective oxide film, which can further improve the corrosion resistance, insulation, and mechanical properties of materials. Traditional anodizing technology is mainly used for aluminum components with large surface areas and regular shapes, such as aluminum plates and profiles. Anodizing is performed on aluminum components using immersion anodizing equipment to form an oxide film on the surface of the aluminum components.

[0003] However, when using immersion oxidation equipment to anodize small-diameter, slender aluminum wires, the slender shape of the wires leads to uneven electric field distribution and imprecise electrolyte temperature control, making it impossible to achieve a stable oxidation reaction. Consequently, the aluminum wires cannot form a uniform and thick oxide film, resulting in weak corrosion resistance, insulation strength, and wear resistance of existing aluminum wires, which restricts the application scenarios and fields of aluminum wires. Summary of the Invention

[0004] Given that existing technologies cannot achieve a stable oxidation reaction of aluminum wire, resulting in the inability to form a uniform and thick oxide film, the corrosion resistance, insulation strength, and wear resistance of existing aluminum wires are relatively weak, limiting their application scenarios and fields. This invention provides an anodizing equipment and process for aluminum wire. By uniformly winding the aluminum wire onto an aluminum wire hanger, controlling a suspended water blowing device to immerse the aluminum wire in the electrolyte solution of the anodizing tank, and applying a rated voltage with a rectifier, the anodizing process integrates a filter, an ice water machine, and a cold water tank, improving the control precision of the anodizing process and the uniformity of the oxidation reaction. This effectively promotes the rapid and dense formation of the oxide film, resulting in a uniform and thick oxide film on the surface of the aluminum wire, enhancing its corrosion resistance, insulation strength, and mechanical wear resistance, and expanding its application capabilities.

[0005] This invention provides an anodizing apparatus for aluminum wire, comprising:

[0006] An anodizing tank is filled with an electrolyte solution, and several cathode plates are installed on the inner wall.

[0007] A cold water tank, connected to the anodizing tank pipeline, is used to input a cooling electrolyte solution into the anodizing tank;

[0008] A chiller, connected to the cold water tank pipeline, is used to cool the electrolyte solution in the cold water tank.

[0009] The filter has its input end connected to the pipeline of the anodizing tank and its output end connected to the pipeline of the cold water tank, and is used to transport the electrolyte solution in the anodizing tank to the cold water tank.

[0017] S4: Start the filter to extract the electrolyte solution from the anodizing tank and transfer it to the cold water tank.

[0018] S5: Start the chiller to cool the electrolyte solution in the chilled water tank.

[0019] S6: Controls the flow of the electrolyte solution cooled in the cold water tank back into the anodizing tank, completing the cooling cycle of the electrolyte solution.

[0020] S7: After the aluminum wire is immersed in the electrolyte solution for 30 to 60 minutes, the suspension blowing device is controlled to suspend the aluminum wire and remove it from the anodizing tank.

[0021] S8: The suspended aluminum wire is dried by blowing water through a suspended water blowing device.

[0022] S9: Detect the oxide film thickness of the aluminum wire.

[0023] Furthermore, the degreasing and oil removal includes: immersing the aluminum wire in an acidic or alkaline solution for 3 to 5 minutes, subjecting the immersed aluminum wire to ultrasonic treatment to shake off surface oil, and then subjecting the immersed aluminum wire to heat treatment at a temperature of 40°C to 70°C.

[0024] Furthermore, the surface alkaline etching includes immersing the aluminum wire in a sodium hydroxide solution at a temperature of 50℃~60℃ for 1min~2min to activate the surface of the aluminum wire.

[0025] Furthermore, the surface neutralization includes immersing the aluminum wire in an acidic solution for 1 to 2 minutes to remove residual ash.

[0026] Furthermore, in step S3, the rectifier supplies electricity to the electrolyte solution at a voltage of 8-20V.

[0027] Furthermore, the temperature of the electrolyte solution in the anodizing tank is maintained at 15℃~25℃.

[0028] Furthermore, in step S7, the drying temperature is 80℃~120℃, and the drying time is 5min-10min.

[0029] Furthermore, the aluminum wire hanger includes: two parallel vertical rods arranged along the y-axis, a main shaft and at least two auxiliary shafts installed between the two parallel vertical rods along the z-axis, a fixing assembly installed on the parallel vertical rods for fixing the starting and ending ends of the aluminum wire, and a suspension assembly installed on the top of the two parallel vertical rods for suspending and hanging. The main shaft is installed on the central axis of the parallel vertical rods, and one end of the main shaft extends out of the parallel vertical rods and connects to the winding output end of the winding machine. The two parallel vertical rods, the main shaft, and the auxiliary shafts are all made of conductive material. The winding machine controls the rotation of the main shaft to wind the aluminum wire around the auxiliary shafts at equal intervals.

[0030] Furthermore, the suspended water blowing device includes: a gantry, a suspension assembly mounted on the inner side of the gantry via a y-axis sliding assembly, two brackets mounted on the bottom ends of both sides of the gantry along the x-axis direction, a traveling water blowing mechanism mounted on each of the brackets via an x-axis sliding assembly, and a crossbar mounted between the two brackets.

[0031] The gantry and the two supports are both located on the upper plane, the anodizing tank is located on the lower plane, the suspension beam is suspended from the bottom of the suspension assembly, the top two sides of the anodizing tank are provided with engaging components that cooperate with the suspension beam, aluminum wire is wound on the aluminum wire hanger, and several aluminum wire hangers are suspended from the suspension beam.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. This invention patent involves uniformly winding aluminum wire onto an aluminum wire hanger, controlling a suspension water blowing device to immerse the aluminum wire in the electrolyte solution of the anodizing tank, and applying a rated voltage with a rectifier. During the anodizing process, a filter, chiller, and cold water tank are integrated to achieve continuous and precise control of the electrolyte solution temperature, ensuring a consistent and stable temperature throughout the anodizing tank. This improves the control precision and uniformity of the anodizing process, effectively promoting the rapid and dense formation of the oxide film. The thicker oxide film further enhances the corrosion resistance, insulation strength, and mechanical wear resistance of the aluminum wire, expanding its application potential in high-end electronic components, precision instruments, and weather-resistant structural parts.

[0034] 2. This invention mounts the main shaft to the winding output end of the winding machine and fixes the end of the aluminum wire to a parallel vertical rod using a fixing assembly. This allows the entire aluminum wire hanger to rotate synchronously when the winding output end of the winding machine rotates, uniformly winding the aluminum wire around multiple auxiliary shafts at equal intervals. This achieves a high-precision, evenly spaced arrangement of the aluminum wires, forming a wire array. By making both the main shaft and auxiliary shafts conductive, the aluminum wire can act as the anode electrode during anodizing, ensuring uniform current flow and rapid formation of a uniform oxide film, further improving process efficiency and quality.

[0048] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0051] Please refer to Figures 1-8 The present invention provides an anodizing device for aluminum wire, comprising: an anodizing tank 1, a cold water tank 2, an ice water machine 3, a filter 4, a rectifier 8, a suspended water blowing device 5, a suspension beam 6, and an aluminum wire hanger 7.

[0052] An electrolyte solution is injected into the anodizing tank 1. A cold water tank 2 is connected to the anodizing tank 1 via a pipe and is used to supply the cooled electrolyte solution into the anodizing tank 1. A chiller 3 is connected to the cold water tank 2 via a pipe and is used to cool the electrolyte solution in the cold water tank 2. The input end of the filter 4 is connected to the anodizing tank 1 via a pipe, and the output end is connected to the cold water tank 2 via a pipe, used to transport the electrolyte solution in the anodizing tank 1 to the cold water tank 2. A suspended water blowing device 5 is installed at the top of the anodizing tank 1. A suspension beam 6 is suspended from the bottom of the suspended water blowing device 5. An aluminum wire hanger 7 is suspended from the suspension beam 6. A rectifier 8 is electrically connected to the anodizing tank 1 and the suspension beam 6 to provide current.

[0053] In this embodiment, aluminum wire is evenly wound onto an aluminum wire hanger 7. The suspended water blowing device 5 is controlled to immerse the aluminum wire in the electrolyte solution of the anodizing tank 1. The rated voltage is applied in conjunction with the rectifier 8. During the anodizing process, the filter 4, the chiller 3, and the cold water tank 2 are integrated to achieve continuous and precise control of the electrolyte solution temperature. This ensures that the electrolyte solution temperature in the anodizing tank 1 is consistent and stable, improving the control precision of the anodizing process and the uniformity of the oxidation reaction. This effectively promotes the rapid and dense formation of the oxide film, resulting in a uniform and thick oxide film on the surface of the aluminum wire. The formation of a thicker oxide film can further enhance the corrosion resistance, insulation strength, and mechanical wear resistance of the aluminum wire, further expanding the application potential of aluminum wire in high-end electronic components, precision instruments, and weather-resistant structural parts.

[0054] like Figure 6 and Figure 7 As shown, the aluminum wire hanger 7 includes: two parallel vertical rods 71 ​​arranged along the y-axis, a main shaft 72 and at least two auxiliary shafts 73 installed between the two parallel vertical rods 71 ​​along the z-axis, a fixing assembly 74 installed on the parallel vertical rods 71 ​​for fixing the starting and ending ends of the aluminum wire, and a suspension assembly 75 installed on the top of the two parallel vertical rods 71 ​​for suspending and hanging. The main shaft 72 is installed on the central axis of the parallel vertical rods 71, and one end of the main shaft 72 extends out of the parallel vertical rods 71 ​​and connects to the winding output end of the winding machine. The two parallel vertical rods 71, the main shaft 72 and the auxiliary shafts 73 are all made of conductive material. The winding machine controls the rotation of the main shaft 72 to wind the aluminum wire onto the auxiliary shafts 73 at equal intervals.

[0055] In this embodiment, by installing the main spindle 72 to the winding output end of the winding machine and fixing the end of the aluminum wire to the parallel vertical rod 71 via the fixing component 74, the entire aluminum wire hanger 7 rotates synchronously when the winding output end of the winding machine is rotated. This allows the aluminum wire to be wound evenly and at equal intervals onto the auxiliary spindle 73, achieving a high-precision, evenly spaced arrangement of the aluminum wires to form a wire array. By making both the main spindle 72 and the auxiliary spindle 73 conductive, the aluminum wire can act as an anode electrode during the subsequent anodizing process, ensuring uniform current flow and rapid formation of a uniform oxide film, further improving process efficiency and quality.

[0056] To further explain, the first end of the aluminum wire is first fixed to one end of the parallel vertical rod 71 by the fixing component 74. Then, the main shaft 72 is installed with the winding output end of the winding machine. The winding machine is started, and the aluminum wire hanger 7 is controlled to rotate synchronously with the winding output end of the winding machine, so that the aluminum wire is evenly and equidistantly wound on the auxiliary shaft 73 set at the first end of the parallel vertical rod 71 and the auxiliary shaft 73 set at the tail end. It is ensured that the aluminum wire establishes an effective contact point with all the auxiliary shafts 73 set between the two parallel vertical rods 71. At this time, the aluminum wire is wound along the y-axis and distributed on the auxiliary shafts 73. After the winding is completed, the tail end of the aluminum wire is fixed by the fixing component 74.

[0057] When anodizing aluminum wire, the aluminum wire hanger 7 of this embodiment, on which the aluminum wire is wound, is immersed in the electrolyte solution of the anodizing tank 1. The electrolyte solution flows through the gap between the auxiliary shafts 73 to achieve uniform oxidation treatment on the surface of the aluminum wire, so that a stable oxide film is formed on the surface of the aluminum wire, which significantly improves the corrosion resistance, hardness and insulation performance of the aluminum wire, thereby enhancing the overall mechanical strength and durability of the aluminum wire.

[0058] Furthermore, the conductive material is made of titanium alloy or aluminum alloy. Titanium alloy has high corrosion resistance, high strength, and light weight, which gives the aluminum wire hanger 7 high resistance to acids and alkalis, improving its durability in oxidizing electrolyte environments. Aluminum alloy has good conductivity, high strength, and hardness, and its base material is the same as that of aluminum wire, avoiding corrosion from dissimilar metal contact. During anodizing, a thin oxide film can be formed on the surface of the aluminum wire hanger 7, further enhancing its resistance to acids and alkalis.

[0059] like Figures 2-5As shown, the suspended water blowing device 5 includes: a gantry 51, a suspension assembly 53 installed inside the gantry 51 via a y-axis sliding assembly 52, two supports 54 installed at the bottom ends of both sides of the gantry 51 along the x-axis direction, a traveling water blowing mechanism 56 installed on each support 54 via an x-axis sliding assembly 55, and a crossbar 57 installed between the two supports 54. The gantry 51 and the two supports 54 are both located on the upper plane, the anodizing tank 1 is located on the lower plane, the suspension beam 6 is suspended from the bottom of the suspension assembly 53, and the top sides of the anodizing tank 1 are provided with engaging assemblies 9 that cooperate with and engage with the suspension beam 6. Aluminum wire is wound on aluminum wire hangers 7, and several aluminum wire hangers 7 are suspended from the suspension beam 6.

[0060] To further explain, the y-axis sliding assembly 52 includes: y-axis slide rails 521 symmetrically installed on both sides of the gantry 51, and sliding members 522 slidably disposed with the y-axis slide rails 521. The suspension assembly 53 is installed on the two sliding members 522 along the x-axis direction.

[0061] To further explain, the suspension assembly 53 includes: a crossbeam 531 mounted on two sliding members 522 along the x-axis direction, and a connector 532 mounted on the crossbeam 531. The suspension beam 6 is suspended from the bottom of the connector 532, and several aluminum wire hangers 7 wrapped with aluminum wire are suspended from the suspension beam 6.

[0062] In this embodiment, the movement of the suspension assembly 53 in the y-axis direction is controlled by driving the y-axis sliding assembly 52, so that the suspension beam 6 moves stably accordingly, thereby realizing the lifting and lowering control of several aluminum wire hangers 7 suspended on the suspension beam 6. Specifically, the connecting frame is provided with a suspension rope connected to the top of the gantry 51. When it is necessary to raise the height of the suspension beam 6, the suspension rope is tightened, and the suspension beam 6 and the aluminum wire hangers 7 suspended on the suspension beam 6 rise synchronously. The crossbeam 531 rises accordingly, driving the sliding member 522 to slide on the y-axis slide rail 521 to assist in the raising of the suspension beam 6. When it is necessary to lower the height of the suspension beam 6, the suspension rope is loosened, and the suspension beam 6 and the aluminum wire hangers 7 suspended on the suspension beam 6 move downward synchronously. The crossbeam 531 lowers accordingly, driving the sliding member 522 to slide on the y-axis slide rail 521 to assist in the lowering of the suspension beam 6.

[0063] Furthermore, the engaging assembly 9 includes: engaging mounting bases 91 symmetrically installed on the top wall of the anodizing tank 1, and engaging grooves 92 provided on the engaging mounting bases 91; both ends of the suspension beam 6 are provided with engaging blocks 61 corresponding to the engaging grooves 92. When the suspension beam 6 moves along the y-axis to the top of the anodizing tank 1, the engaging blocks 61 engage with the engaging grooves 92, thereby stably fixing the suspension beam 6 to the top of the anodizing tank 1. At this time, several aluminum wire hangers 7 suspended on the suspension beam 6 extend into the anodizing tank 1 to perform the anodizing operation of the aluminum wires.

[0064] Furthermore, the suspension beam 6, the locking assembly 9, and the locking block 61 all use the same conductive material as the parallel vertical rod 71. When the rectifier 8 outputs positive current to the suspension beam 6 and simultaneously delivers negative current to the cathode plate 11, the suspension beam delivers the positive current to the aluminum wire hanger 7. Through the conductive action of the main shaft rod 72 and the auxiliary shaft rod 73, and in conjunction with the cathode plate 11 and the electrolyte solution, the aluminum wire is anodized.

[0065] like Figures 2-5 As shown, the traveling water blowing mechanism 56 includes: a motor 561 mounted on a crossbar 57, a traveling drive assembly 562 coaxially mounted with the output shaft of the motor 561, a water receiving tray 563 mounted with the x-axis sliding assembly 55, and a water blowing assembly 564 mounted on the water receiving tray 563. The traveling drive assembly 562 is mounted on the water receiving tray 563.

[0066] Furthermore, the vehicle drive assembly 562 includes: a rotating rod 5621 coaxially mounted along the z-axis direction with the output shaft of the motor 561 via a gearbox; control gears 5622 disposed at both ends of the rotating rod 5621; and racks 5623 mounted along the x-axis direction on both sides of the water receiving tray 563 and meshing with the control gears 5622. When the motor 561 controls the rotating rod 5621 to rotate, the control gears 5622 and racks 5623 mesh to drive the water blowing assembly 564 to move and blow water onto several aluminum wire hangers 7 with wound aluminum wires suspended on the suspension beam 6.

[0067] Furthermore, the water blowing assembly 564 includes: two 7-shaped hollow rods 5641 installed at the tail end of the water receiving tray 563 along the x-axis direction, a hollow connecting rod 5642 connected to the ends of the two 7-shaped hollow rods 5641, a number of air knife components 5643 installed on the hollow connecting rod 5642 along the z-axis direction, a high-pressure air pump installed externally, and an air pipe installed at the output end of the high-pressure air pump. The air pipe passes through the 7-shaped hollow rods 5641 and the hollow connecting rod 5642 in sequence, and the end of the air pipe is inserted into the air knife component 5643.

[0068] Furthermore, there is a water blowing cavity 58 between the water blowing assembly 564 and the water receiving tray 563. When the suspension beam 6 moves to the same horizontal plane as the water blowing cavity 58, the water blowing assembly 564 moves along the x-axis to blow water onto the aluminum wire hangers 7 with several wound aluminum wires suspended on the suspension beam 6.

[0069] In this embodiment, the motor 561 drives the trolley drive assembly 562 in coordination with the x-axis sliding assembly 55 to achieve precise movement of the water receiving tray 563 along the x-axis direction. This allows the water blowing assembly 564 to work synchronously with the water receiving tray 563 to efficiently blow water onto the aluminum wire hangers 7 with wound aluminum wires suspended on the suspension beam 6. Specifically, a high-speed airflow is controlled to blow out from the air knife 5643. Through the continuous movement of the water receiving tray 563 along the positive x-axis, the high-speed airflow blows water onto the aluminum wire hangers 7 with wound aluminum wires suspended on the suspension beam 6 from the tail end to the head end, and the dripping water falls into the water receiving tray 563. Subsequently, the water receiving tray 563 is controlled to move in the opposite x-axis direction to achieve a second water blowing from the head end to the tail end. The bidirectional reciprocating water blowing structure of this embodiment can automatically and thoroughly dry the aluminum wires wound on the aluminum wire hangers 7, significantly improving the cleanliness and drying quality of the aluminum wire surface.

[0070] In this embodiment, when the y-axis sliding assembly 52 assists the suspension assembly 53 in sliding until the suspension beam 6 and the water blowing chamber 58 are located on the same x-axis plane, the motor 561 is started, and the rotating rod 5621 rotates forward accordingly, driving the control gears 5622 set at both ends to rotate forward synchronously. Through the meshing of the control gears 5622 and the rack 5623, the water receiving tray 563 and the water blowing assembly 564 are controlled to move towards the suspension beam 6 along the x-axis direction. As the water receiving tray 563 and the water blowing assembly 564 continue to move, the high-pressure pump is started simultaneously, so that the high-pressure airflow is sprayed out from the air knife 5643. As the water receiving tray 563 and the water blowing assembly 564 continue to move along the x-axis direction, several aluminum wire hangers 7 with aluminum wires wound on the suspension beam 6 are gradually inserted into the water blowing chamber 58, and the high-pressure airflow sprayed out from the air knife 5643 also performs the first water blowing operation on the aluminum wires on the aluminum wire hangers 7 during the movement.

[0071] When the control gear 5622 meshes with the rack 5623 to the end of the rack 5623, the aluminum wire hanger 7 is fully embedded in the water blowing chamber 58 and remains in this state. At this time, the control motor 561 reverses, the rotating rod 5621 rotates in the opposite direction, and drives the control gears 5622 set at both ends to rotate in the opposite direction synchronously. Through the meshing of the control gear 5622 and the rack 5623, the water receiving tray 563 and the water blowing assembly 564 are controlled to move away from the suspension beam 6 along the x-axis. During this movement, the air knife 5643 continuously sprays high-pressure airflow to perform a secondary water blowing operation on the aluminum wire on the aluminum wire hanger 7.

[0072] Furthermore, the two-stage water-blowing process improves both the water-blowing effect and operational efficiency. The first water-blowing occurs simultaneously with the aluminum wire hanger 7 entering the water-blowing chamber 58, where a high-pressure airflow initially dries the aluminum wire on the hanger 7 from the tail end to the head end. Subsequently, the aluminum wire hanger 7 is fully embedded in the water-blowing chamber 58. At this point, by controlling the reverse movement of the water receiving tray 563 and the water-blowing assembly 564, a second reverse drying process is performed on the aluminum wire on the hanger 7 from the head end to the tail end, improving the cleanliness and dryness of the aluminum wire surface and effectively ensuring the efficiency of the water-blowing operation.

[0073] To further explain, the 7-shaped hollow rod 5641 includes a horizontal section and a vertical section. The distance between the horizontal sections of the two 7-shaped hollow rods 5641 must be greater than the length of the aluminum wire hangers 7 hanging on the suspension beam, so that the aluminum wire hangers 7 can be completely embedded in the water blowing chamber 58. This ensures that the water blowing range of the air knife set on the hollow connecting rod 5642 can cover all the aluminum wire hangers, thus ensuring the efficiency of the aluminum wire water blowing operation.

[0074] like Figures 1-8 As shown, the present invention also provides an anodizing process for an aluminum wire anodizing device, comprising the following steps:

[0075] S1: The aluminum wire to be processed is evenly wound on the aluminum wire hanger 7 to perform surface pretreatment on the aluminum wire, and then the aluminum wire is anodized. The surface pretreatment includes: degreasing and oil removal, surface alkaline etching, and surface neutralization.

[0076] S2: Suspend the aluminum wire hanger 7 on the suspension beam 6 and control the suspension water blowing device 5 to completely immerse the aluminum wire in the electrolyte solution of the anodizing tank 1.

[0077] S3: Control the rectifier 8 to supply negative current to the cathode plate 11, and at the same time supply positive current to the suspension beam 6.

[0078] S4: Start the filter 4 to extract the electrolyte solution from the anodizing tank 1 and transfer it to the cold water tank 2.

[0079] S5: Start the chiller 3 to cool the electrolyte solution in the cold water tank 2.

[0080] S6: Control the flow of the electrolyte solution cooled in the cold water tank 2 back into the anodizing tank 1 to complete the cooling cycle of the electrolyte solution.

[0081] S7: After the aluminum wire is immersed in the electrolyte solution for 30 to 60 minutes, the suspension blowing device 5 is used to suspend the aluminum wire and remove it from the anodizing tank 1.

[0082] S8: The suspended aluminum wire is dried by blowing water through the suspended water blowing device 5.

[0083] S9: Detect the oxide film thickness of the aluminum wire.

[0084] To further explain, the aluminum wire needs to be degreased and deoiled first, then its surface is alkali-etched, and finally its surface is neutralized.

[0085] To further explain, the degreasing and oil removal process includes: first, immersing the aluminum wire in an acidic or alkaline solution for 3 to 5 minutes; then, subjecting the immersed aluminum wire to ultrasonic treatment to shake off surface oil; and finally, heating the immersed aluminum wire at a temperature of 40°C to 70°C.

[0086] To further explain, the surface alkaline etching process includes immersing the aluminum wire in a sodium hydroxide solution at a temperature of 50℃~60℃ for 1min~2min to activate the surface of the aluminum wire.

[0087] To further explain, surface neutralization includes immersing the aluminum wire in an acidic solution for 1 to 2 minutes to remove the ash residue remaining after alkaline etching.

[0088] Furthermore, the temperature of the electrolyte solution in anodizing tank 1 is maintained at 15℃~25℃.

[0089] To further explain, in step S3, the rectifier 8 is energized into the electrolyte solution with a voltage of 8V~20V.

[0090] To further clarify, in step S7, the drying temperature is 80℃~120℃, and the drying time is 5min~10min.

[0091] In this embodiment, the surface of the pretreated aluminum wire is in an activated state, suitable for anodizing. The aluminum wire is then uniformly and stably wound onto the aluminum wire hanger 7 by a winding machine. Multiple aluminum wire hangers 7 are sequentially hung on the suspension beam 6. The suspension assembly 53 is controlled to move downwards along the y-axis, causing the suspension beam 6 and the aluminum wire hangers 7 to move downwards synchronously. At this time, the y-axis sliding assembly 52 slides accordingly to maintain the balance of the suspension assembly 53 and the suspension beam 6. When the locking blocks 61 at both ends of the suspension beam 6 engage with the locking grooves 92 at the top of the anodizing tank 1, the suspension beam 6 is fixedly engaged at the top of the anodizing tank 1. At this point, the aluminum wire on the aluminum wire hanger 7 is completely immersed in the electrolyte solution in the anodizing tank 1. Then, the rectifier 8 is started, supplying positive current to the suspension beam 6 and simultaneously supplying negative current to the cathode plate 11. The positive current is transmitted through the suspension beam 6 to the aluminum wire hanger 7 and further to the wound aluminum wire. At this time, the aluminum wire is the anode and the cathode plate 11 is the cathode. With the cooperation of the electrolyte solution, the aluminum wire at the anode is anodized. The supply voltage is controlled at 8V~20V, so that a thicker oxide film can be generated on the surface of the aluminum wire, which improves the corrosion resistance, hardness and insulation performance of the aluminum wire, further enhances the mechanical strength and durability of the aluminum wire, and broadens the application range of the aluminum wire.

[0092] Furthermore, during the anodizing process, the electrolyte solution heats up as the anodizing progresses, leading to a decrease in the anodizing effect and consequently, a poor quality oxide film. Therefore, it is necessary to circulate and cool the electrolyte solution within the anodizing tank 1. This is achieved by simultaneously activating the filter 4 and the chiller 3. The filter 4 extracts the heated electrolyte solution from the anodizing tank 1 and transfers it to the chiller 2. The chiller 3 cools the electrolyte solution in the chiller 2, and then the cooled electrolyte solution is returned to the anodizing tank 1, forming a cooling cycle. This ensures that the temperature of the electrolyte solution within the anodizing tank 1 is maintained between 15℃ and 25℃, thereby guaranteeing the anodizing effect on the aluminum wire.

[0093] After the aluminum wire and its hanger are immersed in the electrolyte solution for 30-60 minutes, the suspension assembly 53 is controlled to move upward along the y-axis, causing the suspension beam 6 and the aluminum wire hanger 7 to move upward synchronously. At this time, the y-axis sliding assembly 52 slides synchronously to maintain the stability of the suspension beam 6 and the aluminum wire hanger 7. Through the continuous upward movement of the suspension assembly 53 along the y-axis, the aluminum wire hanger 7 gradually leaves the electrolyte solution, and the rectifier 8, filter 4, and chiller 3 are shut down simultaneously. When the aluminum wire hanger 7 is completely removed from the electrolyte solution, the anodizing process is completed, and an oxide film with a thickness of 4μm-6μm has been formed on the surface of the aluminum wire.

[0094] When the suspension beam 6 moves along the y-axis into the water blowing chamber 58, the motor 561 is started, controlling the trolley drive assembly 562 to coordinate with the x-axis sliding assembly 55, so as to realize the synchronous and precise movement of the water receiving tray 563 and the water blowing assembly 564 along the x-axis. The high-pressure pump is started, so that the high-pressure airflow is sprayed out from the air knife 5643 to blow water on the aluminum wire on the aluminum wire hanger 7. By controlling the forward and reverse rotation of the motor 561, the bidirectional reciprocating water blowing operation on the aluminum wire on the aluminum wire hanger 7 is realized, further improving the cleanliness and dryness of the aluminum wire.

[0095] Then all the aluminum wire hangers 7 were removed from the suspension beam 6, and the aluminum wire hangers 7 and the aluminum wires wrapped around them were dried at a temperature of 80℃~120℃ for 5min-10min.

[0096] A small section of aluminum wire is ground and placed under an electron microscope for observation. The thickness of the oxide film produced by the aluminum wire is measured to check whether the thickness of the oxide film on the aluminum wire meets the standard.

[0097] Furthermore, the cathode plate 11 is made of lead or lead alloy, which has high resistance to sulfuric acid corrosion and can form a dense protective film on the surface, which can greatly delay further corrosion, thereby ensuring long-term stable operation and long service life, and can assist in the stable operation of anodizing.

[0098] It should be understood that the specific embodiments described above are for illustrative purposes only and are not intended to limit the scope of the invention. Obvious variations or modifications derived from the spirit of the invention are still within the protection scope of the invention.
