Technical Field
[0001] The present invention relates to the technical field of anodizing, and in particular to an anodizing treatment device and process for metal shells of electronic products. Background Art
[0002] In the electronics manufacturing industry, metal casings are key components that protect electronic components and enhance product appearance and quality. Therefore, their surface treatment processes are crucial. Anodizing, a commonly used metal surface treatment technology, forms a dense oxide film on the metal surface, which not only improves the metal's corrosion resistance, wear resistance, and hardness, but also imparts a specific color and gloss to the metal casing, meeting the dual demands of aesthetics and practicality for electronic products. However, traditional anodizing equipment and methods often have some problems when clamping metal shells for oxidation treatment. On the one hand, the clamped parts of the metal shells are easily subjected to clamping force for a long time, which easily forms clamping marks or uneven oxidation during the oxidation process, affecting the appearance quality and performance of the metal shells. On the other hand, traditional anodizing equipment often lacks an effective electrolyte disturbance mechanism during the treatment process, resulting in limited ion diffusion rate in the electrolyte and serious concentration polarization, which in turn affects the quality and thickness uniformity of the oxide film.

[0014] A process for anodizing a metal shell of an electronic product, comprising the following steps: S1. Adjust the position of the upper and lower clamping plates: Rotate the knob on the outside of the power box to rotate the worm gear through the worm, which in turn drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod causes the upper clamping plate and the lower clamping plate to move axially along the bidirectional threaded rod, thereby adjusting the distance between the upper clamping plate and the lower clamping plate; S2. Metal shell hanging process: Place the metal shell vertically between the upper clamping plate and the lower clamping plate, aligning the edge of the shell with the clamping rod. The clamping rod maintains the clamping of the metal shell under the action of the alternating clamping assembly. S3. Anodizing process: Connect the metal shell to the positive pole of the power supply, and the corrosion-resistant metal of the cathode in the electrolyte container to the negative pole of the power supply to form a circuit. Inject electrolyte into the electrolyte container and completely immerse the metal shell in the electrolyte through the hook on the side of the power box. After the power is turned on, the shell acts as the anode to undergo oxidation reaction, and an oxide film is formed on the surface. During the oxidation process, the clamping rods will alternately clamp under the drive of the drive component, and at the same time, the vibration plate will vibrate; S4, alternating clamping process: The driving assembly drives the sector friction wheel through the motor to alternately rub the first friction wheel and the second friction wheel, so that the spline rod rotates back and forth at a certain angle, and the spline rod drives the turntable to rotate accordingly. During the rotation of the turntable, the slide rod drives the slide rod to make a circular motion with the axis of the turntable as the center through the slide groove, and the first connecting rod is pushed away from the turntable by the slide rod to make the second connecting rod or the third connecting rod slide in the direction away from the turntable. The push block fixedly connected to the bottom of the second connecting rod or the third connecting rod will move away from the turntable and compress the spring. The rack drives the sector gear to rotate, and then drives the fourth connecting rod to rotate around the axis of the sector gear. The fourth connecting rod drives the arc rod and the clamping rod to move synchronously, and the multiple groups of clamping rods installed in conjunction with the second connecting rod or the third connecting rod release the clamping of the metal shell; S5. Vibration process: When the spline rod rotates back and forth, the bottom face gear rotates synchronously, driving the multiple spur gears meshing with it to rotate back and forth. The spur gears drive the rotating rod to rotate back and forth. The vibration plate vibrates as the rotating rod rotates back and forth. The vibration wave is transmitted to the electrolyte, breaking the concentration polarization layer, accelerating ion diffusion, and improving the quality of the oxide film. S6, removal process: After the oxidation is completed, the device is taken out from the electrolyte container and the metal shell is removed.
[0015] Compared with related technologies, the anodizing treatment device and process for metal shells of electronic products provided by the present invention have the following beneficial effects: Improved uniformity and quality of oxide film: The present invention realizes alternate clamping of the metal shell during the anodic oxidation process by using an alternating clamping assembly. This design avoids the obstruction of the metal shell's clamped parts from oxidation during the long clamping process caused by the traditional clamping structure, ensuring that all parts of the metal shell surface can undergo uniform anodic oxidation reaction, thereby improving the uniformity and quality of the oxide film. Improved efficiency and quality of anodizing: The vibration component generates vibration waves through the vibration plate and transmits them to the electrolyte, effectively breaking the concentration polarization layer. This innovative design accelerates the diffusion of ions, allowing ions in the electrolyte to reach the surface of the metal shell more quickly, promoting the oxidation reaction and further improving the quality and thickness of the oxide film. Improved device flexibility: The adjustment assembly realizes the precise adjustment of the distance between the upper clamping plate and the lower clamping plate through the cooperation of the bidirectional threaded rod, worm gear and worm. This design enables the invention to adapt to metal shells of different sizes, improving the versatility and flexibility of the equipment. Easy to operate, safe and reliable: The operation process of the present invention is simple and easy to understand. The distance between the upper clamping plate and the lower clamping plate can be adjusted by rotating the knob. The alternating clamping and anodizing treatment of the metal shell can be achieved by motor drive. At the same time, the protective shell on the side wall of the power box and the anti-slip pattern on the side wall of the knob also improve the safety and reliability of the equipment.

[0021] A process for anodizing a metal shell of an electronic product, comprising the following steps: S1. Adjust the position of the upper clamping plate 3 and the lower clamping plate 4: Rotate the knob 30 on the outside of the power box 1 to rotate the worm gear 7 through the worm 8, which in turn drives the bidirectional threaded rod 6 to rotate. The rotation of the bidirectional threaded rod 6 causes the upper clamping plate 3 and the lower clamping plate 4 to move axially along the bidirectional threaded rod 6, thereby adjusting the distance between the upper clamping plate 3 and the lower clamping plate 4; S2. Metal shell hanging process: Place the metal shell vertically between the upper clamping plate 3 and the lower clamping plate 4, so that the edge of the shell is aligned with the position of the clamping rod 25. The clamping rod 25 maintains the clamping of the metal shell under the action of the alternating clamping assembly; S3. Anodizing process: Connect the metal shell to the positive electrode of the power supply, and connect the corrosion-resistant metal of the cathode in the electrolyte container to the negative electrode of the power supply to form a circuit. Inject electrolyte into the electrolyte container, and immerse the metal shell completely in the electrolyte through the hook 35 on the side of the power box 1. After the power is turned on, the shell acts as the anode to undergo oxidation reaction, and an oxide film is formed on the surface. During the oxidation process, under the drive of the drive assembly, the clamping rod 25 will alternately clamp, and at the same time, the vibration plate 29 will vibrate. S4, alternating clamping process: The driving assembly drives the sector friction wheel 12 through the motor 32 to alternately rub the first friction wheel 10 and the second friction wheel 11, so that the spline rod 2 rotates reciprocatingly at a certain angle, and the spline rod 2 drives the turntable 13 to rotate accordingly. During the rotation of the turntable 13, the slide rod 15 drives the slide rod 15 through the slide groove 14 to make a circular motion with the axis of the turntable 13 as the center. The slide rod 15 pushes the first connecting rod 16 away from the turntable 13, so that the second connecting rod 17 or the third connecting rod 18 slides in the direction away from the turntable 13. The push block 19 fixedly connected to the bottom of the second connecting rod 17 or the third connecting rod 18 will accordingly move away from the turntable 13 and compress the spring 20. The rack 22 drives the sector gear 21 to rotate, and then drives the fourth connecting rod 23 to rotate around the axis of the sector gear 21. The fourth connecting rod 23 drives the arc rod 24 and the clamping rod 25 to move synchronously, and the multiple groups of clamping rods 25 installed in conjunction with the second connecting rod 17 or the third connecting rod 18 release the clamping of the metal shell; S5. Vibration process: When the spline rod 2 rotates back and forth, the bottom face gear 26 rotates synchronously, driving the multiple spur gears 27 meshing with it to rotate back and forth. The spur gears 27 drive the rotating rod 28 to rotate back and forth. The vibration plate 29 rotates back and forth with the rotating rod 28 to generate vibration. The vibration wave is transmitted to the electrolyte, breaking the concentration polarization layer, accelerating ion diffusion, and improving the quality of the oxide film. S6, removal process: After the oxidation is completed, the device is taken out from the electrolyte container and the metal shell is removed.
[0022] The working principle of the anodizing treatment device for metal shells of electronic products provided by the present invention is as follows: Adjust the position of the upper clamping plate 3 and the lower clamping plate 4: By rotating the knob 30 on the outside of the power box 1, the worm 8 rotates synchronously. Since the worm wheel 7 is meshed with the worm 8, the rotation of the worm 8 drives the worm wheel 7 to rotate. The top of each bidirectional threaded rod 6 is fixedly connected to the worm wheel 7, so the bidirectional threaded rod 6 rotates accordingly. The bidirectional threaded rod 6 is threadedly connected to the upper clamping plate 3 and the lower clamping plate 4. The rotation of the bidirectional threaded rod 6 causes the upper clamping plate 3 and the lower clamping plate 4 to move axially along the bidirectional threaded rod 6, thereby adjusting the distance between the upper clamping plate 3 and the lower clamping plate 4 to adapt to metal shells of different sizes. The anti-slip grooves on the side wall of the knob 30 can increase friction, making it easier for the operator to turn the knob 30. The protective shell 31 rotatably connected to the side wall of the power box 1 can protect the rotating worm 8 and other components to prevent accidental touch; Metal shell hanging process: The second and third connecting rods 17 and 18 are reset by the second and third connecting rods 17 and 18 respectively, and the second and third connecting rods 17 and 18 are reset by the second and third connecting rods 17 and 18 respectively. Anodizing process: Connect the metal shell to the positive electrode of the power supply, and connect the corrosion-resistant metal of the cathode in the electrolyte container to the negative electrode of the power supply to form a circuit. Inject electrolyte into the electrolyte container and completely immerse the metal shell in the electrolyte through the hook 35 on the side of the power box 1. When the power is turned on, the shell acts as the anode to undergo oxidation reaction, and an oxide film is formed on the surface. Alternating clamping process: In the initial state, the middle part of the friction part of the sector friction wheel 12 is frictionally connected with the first friction wheel 10, and the motor 32 drives the sector friction wheel 12 to alternately rub the first friction wheel 10 and the second friction wheel 11, so that the spline rod 2 rotates back and forth at a certain angle. When the sector friction wheel 12 is frictionally connected with the first friction wheel 10, the spline rod 2 rotates forward, and the spline rod 2 drives the turntable 13 to rotate forward through the internal spline 33. During the rotation process, the turntable 13 drives the slide rod 15 to make a circular motion with the axis of the turntable 13 as the center through the slide groove 14, and the slide rod 15 pushes the first friction wheel 10 to rotate back and forth. A connecting rod 16 moves away from the turntable 13. The first connecting rod 16 pushes the second connecting rod 17 to slide away from the turntable 13. The push block 19 fixedly connected to the bottom of the second connecting rod 17 moves away from the turntable 13 and compresses the spring 20. The rack 22 fixedly connected to the top of the second connecting rod 17 drives the sector gear 21 to rotate, thereby driving the fourth connecting rod 23 to rotate around the axis of the sector gear 21. The fourth connecting rod 23 drives the arc rod 24 and the clamping rod 25 to move synchronously. The multiple groups of clamping rods 25 installed in conjunction with the second connecting rod 17 release the clamping of the metal shell. When the sector-shaped friction wheel 12 is frictionally connected with the second friction wheel 11, the spline rod 2 rotates in the opposite direction, and the spline rod 2 drives the turntable 13 to rotate in the opposite direction through the internal spline 33. During the rotation of the turntable 13, the slide rod 15 drives the slide rod 15 through the slide groove 14 to make a circular motion with the axis of the turntable 13 as the center. As the turntable 13 continues to reverse, the second connecting rod 17 will gradually reset under the elastic force of the spring 20, and the multiple groups of clamping rods 25 installed in conjunction with the second connecting rod 17 will re-clamp the metal shell. When the second connecting rod 17 is reset, the turntable 13 will continue to reverse, and the slide groove 14 will gradually approach and push the third connecting rod 18 to match The sliding rod 15 is installed together, and the sliding rod 15 pushes the first connecting rod 16 away from the turntable 13. The first connecting rod 16 pushes the third connecting rod 18 to slide in the direction away from the turntable 13. The push block 19 fixedly connected to the bottom of the third connecting rod 18 will then move away from the turntable 13 and compress the spring 20. The rack 22 fixedly connected to the top of the third connecting rod 18 drives the sector gear 21 to rotate, and then drives the fourth connecting rod 23 to rotate around the axis of the sector gear 21. The fourth connecting rod 23 drives the arc rod 24 and the clamping rod 25 to move synchronously, and the multiple groups of clamping rods 25 installed in conjunction with the third connecting rod 18 release the clamping of the metal shell; When the sector-shaped friction wheel 12 is frictionally connected with the first friction wheel 10 again, the spline rod 2 rotates forward, and the spline rod 2 drives the turntable 13 to rotate forward through the internal spline 33. During the rotation process, the turntable 13 drives the slide rod 15 through the slide groove 14 to make a circular motion with the axis of the turntable 13 as the center. As the turntable 13 rotates forward, the third connecting rod 18 is gradually reset under the elastic force of the spring 20, and the multiple groups of clamping rods 25 installed in conjunction with the third connecting rod 18 re-clamp the metal shell. When the third connecting rod 18 is reset, the turntable 13 continues to rotate forward, so that the multiple groups of clamping rods 25 installed in conjunction with the second connecting rod 17 release the clamping of the metal shell. Vibration process: When the spline rod 2 rotates back and forth, the bottom face gear 26 rotates synchronously, driving the multiple spur gears 27 meshing with it to rotate back and forth. The spur gears 27 drive the rotating rod 28 to rotate back and forth. The vibration plate 29 rotates back and forth with the rotating rod 28 to generate vibration.

The rotation of the bidirectional threaded rod (6) causes the upper clamping plate (3) and the lower clamping plate (4) to move axially along the bidirectional threaded rod (6), thereby adjusting the distance between the upper clamping plate (3) and the lower clamping plate (4); S2. Metal shell hanging process: The metal shell is vertically placed between the upper clamping plate (3) and the lower clamping plate (4), so that the edge of the shell is aligned with the position of the clamping rod (25), and the clamping rod (25) maintains the clamping of the metal shell under the action of the alternating clamping assembly; S3.

The electrolyte is injected into the electrolyte container, and the metal shell is completely immersed in the electrolyte through the hook (35) on the side of the power box (1). After the power is turned on, the shell acts as an anode to undergo an oxidation reaction, and an oxide film is formed on the surface.

The vibration plate (29) generates vibration as the rotating rod (28) rotates back and forth. The vibration wave is transmitted to the electrolyte, breaking the concentration polarization layer, accelerating ion diffusion, and improving the quality of the oxide film; S6, removal process: After the oxidation is completed, the device is taken out from the electrolyte container and the metal shell is removed.
