Description

Technical Field

[0001] The present invention belongs to the technical field of optical module manufacturing, and particularly relates to a high-temperature resistant surface treatment process for optical modules based on composite electroplating. Background Art

[0002] With the rapid development of optical communication technology, optical modules are increasingly widely used in data centers, 5G communications, and high-speed optical transmission systems. However, in harsh environments such as high temperature, high humidity, and strong electromagnetic interference, the surface coatings of traditional optical modules are prone to problems such as oxidation, thermal fatigue, and decreased mechanical properties, resulting in reduced signal transmission stability and even device failure. To improve the high-temperature resistance and mechanical strength of optical modules, composite electroplating technology has become a research hotspot in the field of surface treatment in recent years because it can embed high-temperature resistant materials or fibers in the metal coating, significantly improving the thermal stability, hardness, and wear resistance of the coating. Traditional composite electroplating technology forms a metal-ceramic composite coating on the surface of the substrate by adding micron or nanoscale ceramic particles (such as SiC, Al2O3) or high-melting-point fibers (such as carbon fiber, ceramic fiber) to the electroplating solution (such as nickel-based, cobalt-based plating solutions) and using the principle of co-deposition. Such coatings not only inherit the electrical conductivity and toughness of metals but also have excellent high-temperature oxidation resistance and mechanical properties due to the dispersed high-temperature resistant phases.

[0003] However, in the surface treatment of optical modules with existing composite electroplating processes, it is difficult to achieve uniform suspension of nanoparticles by traditional mechanical stirring or single ultrasonic dispersion, resulting in particle agglomeration and sedimentation in the electroplating solution, and component segregation or increased porosity in the coating, which seriously affects the high-temperature resistance and bonding strength. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a high-temperature resistant surface treatment process for optical modules based on composite electroplating, which can solve problems such as uneven dispersion of particles / fibers and low co-deposition efficiency, thereby preparing a composite coating with high density, high particle content, and outstanding high-temperature resistance, meeting the long-term reliable operation requirements of optical modules in extreme environments.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] The high-temperature resistant surface treatment process for optical modules based on composite electroplating disclosed by the present invention includes the following steps:

[0007] Step 1, adding the pretreated high-temperature resistant material to the electroplating solution, and starting the ultrasonic dispersion device to perform premixing in the electroplating tank for 30 - 60 minutes;

[0008] Step 2, performing electroplating using a pulse power supply. During electroplating, the forward current density is 3 - 8 A / dm 2 , the duty cycle is 30% - 70%, and the reverse time is 0.5 - 2 ms;

[0009] Step 3: Continuously turn on ultrasonic dispersion during electroplating, and monitor the agglomeration position of the high-temperature resistant material in real time. Move the fixed-point stirring device to the corresponding agglomeration position and start it. Stir the electroplating solution at this position through the fixed-point stirring device to maintain the dispersion stability of the high-temperature resistant material.

[0010] Furthermore, the high-temperature resistant material is SiC or Al2O3 or ceramic fiber or carbon fiber. The addition amount of the high-temperature resistant material is 5% - 20% of the mass of the electroplating solution, and the high-temperature resistant material is pretreated with a silane coupling agent to enhance the bonding force with the coating.

[0011] Furthermore, the electroplating solution is a nickel-based or cobalt-based plating solution, with a pH value of 4.0 - 5.5, a temperature of 45 - 65 °C, an electroplating time of 20 - 60 min, and the porosity of the surface coating of the optical module ≤ 1.5%.

[0012] Furthermore, the fixed-point stirring device includes a motor, a rotating ring connected to the output end of the motor, and a rotating rod coaxially connected to the rotating ring. A rotating blade is installed on the outer side of the rotating rod. The notch of the electroplating tank forms a plane, and a cover plate is slidably installed on the upper side of the notch. The motor is fixed to the cover plate. By moving the cover plate on the upper surface of the notch, the stirring position of the fixed-point stirring device can be changed.

[0013] Furthermore, a limiting ring is rotatably fitted on the outer side of the rotating rod. A support rod is fixed on the outer side of the limiting ring, and multiple support rods are evenly spaced along the circumferential direction of the limiting ring. The outer end of the support rod is hinged with an arc-shaped shell, and a deflection control device for controlling the deflection of the arc-shaped shell is connected between the support rod and the arc-shaped shell; when moving the fixed-point stirring device to a specified position, the deflection control device controls the arc-shaped shell to open. After reaching the specified position, the deflection control device controls the arc-shaped shell to close. Multiple arc-shaped shells can be combined to form a cylindrical limiting cover with the rotating rod as the axis, restricting the agglomerates of the high-temperature resistant material therein. The limiting cover is located outside the rotating blade and can restrict the displacement of the agglomerates.

[0014] Furthermore, arc-shaped limiting guide rails are fixed on the inner wall of the arc-shaped shell. A notch for the rotating blade to cooperate is formed inside the arc-shaped limiting guide rails. A telescopic device is fixed on the outer wall of the arc-shaped shell. The output end of the telescopic device extends along the axial direction of the arc-shaped shell and is connected to the arc-shaped limiting guide rails. The arc-shaped limiting guide rails can be pushed to displace axially through the telescopic device. The rotating blade and the rotating rod are in frictional fit in the axial direction, and the arc-shaped limiting guide rails can drive the rotating blade to displace.

[0015] Further, a guide hole is provided at the lower end of the arc-shaped housing. A guide rod is slidably installed in the guide hole. The guide rod is fixedly connected to a magnetic base. The magnetic base is connected to the arc-shaped housing through an elastic connection device. An electromagnet is installed at the bottom of the electroplating tank. After moving the fixed-point stirring device to a specified position, the electromagnet is activated. The electromagnet attracts the magnetic base, and the magnetic base can limit the circumferential direction of the arc-shaped housing.

[0016] Further, a fixed blade is connected to the outer side of the rotating rod in a matching manner, and a stop member for restricting the rotation of the fixed blade is installed inside the arc-shaped housing.

[0017] Further, the rotating rod includes an upper rod, a plug rod, and a lower rod. The plug rod is fixedly connected to the upper rod, and the plug rod is inserted and matched with the lower rod. An inner sleeve is connected to the outer side of the plug rod. A plurality of relief grooves are evenly formed on the outer circumference of the inner sleeve. A clamping plate is hinged in the relief groove. A torsion reset device is installed between the clamping plate and the inner sleeve. An outer sleeve is coaxially installed on the outer side of the inner sleeve. Clamping teeth corresponding to the clamping plate are formed on the inner wall of the outer sleeve. The outer sleeve is installed at the center of the fixed blade.

[0018] Further, the rotating ring is connected to the rotating rod through an elastic spiral coil, and a fan blade is simultaneously connected to the lower end of the rotating rod.

[0019] The beneficial effects of the present invention are as follows:

[0020] A high-temperature resistant surface treatment process for optical modules based on composite electroplating disclosed by the present invention solves the problem of local agglomeration of particles caused by gravity sedimentation or charge adsorption in traditional composite electroplating by real-time monitoring of the agglomeration position and starting fixed-point stirring. By dynamically adjusting the stirring position, it can ensure that the high-temperature resistant materials in the electroplating solution are always in a uniformly suspended state, thereby avoiding problems such as composition segregation or increased porosity in the coating.

Specific implementation manners

[0032] As Figure 1 shown, the high-temperature resistant surface treatment process for optical modules based on composite electroplating disclosed by the present invention includes the following steps:

[0033] Step 1: Add the pretreated high-temperature resistant material into the electroplating solution, and start the ultrasonic dispersion device to perform premixing in the electroplating tank for 30 - 60 min; By using ultrasonic premixing for 30 - 60 minutes, it can effectively break the initial agglomeration of high-temperature resistant materials such as SiC, Al2O3 particles or ceramic fibers, and ensure their uniform distribution in the electroplating solution.

[0034] Step 2: Perform electroplating using a pulsed power supply. During electroplating, the forward current density is 3 - 8 A / dm 2 , the duty cycle is 30% - 70%, and the reverse time is 0.5 - 2 ms; By adopting the above process, it can promote the co-deposition of high-temperature resistant materials and metal ions, and improve the density of the coating.

[0035] Step 3: Continuously turn on the ultrasonic dispersion during the electroplating process, and real-time monitor the agglomeration position of the high-temperature resistant material. Move the fixed-point stirring device to the corresponding agglomeration position and start it, and stir the electroplating solution at this position through the fixed-point stirring device to maintain the dispersion stability of the high-temperature resistant material.

[0036] Furthermore, the high-temperature resistant material of the present invention is SiC or Al2O3 or ceramic fiber or carbon fiber. The addition amount of the high-temperature resistant material is 5% - 20% of the mass of the electroplating solution, which significantly improves the oxidation resistance of the coating in high-temperature environments. Moreover, the high-temperature resistant material is pretreated with a silane coupling agent to enhance the bonding force with the coating, meeting the long-term reliability requirements of the optical module under extreme working conditions.

[0037] The electroplating solution uses a nickel-based or cobalt-based electroplating solution, with a pH value of 4.0 - 5.5, a temperature of 45 - 65 °C, an electroplating time of 20 - 60 min, and the porosity of the surface coating of the optical module ≤ 1.5%. Nickel provides good ductility and conductivity, and cobalt can improve the high-temperature hardness of the coating. By setting a reasonable pH value and temperature, this range can not only ensure the stability of the electroplating solution but also avoid excessive acidity causing particle dissolution or excessive temperature causing the electroplating solution to volatilize. Using the above electroplating time ensures uniform coating thickness, and at the same time, intermittent deposition through a pulsed power supply reduces internal stress.

[0038] As Figures 2 - 8 shown, in the present invention, the fixed-point stirring device includes a motor 1, a rotating ring 2 connected to the output end of the motor 1, and a rotating rod 3 coaxially connected to the rotating ring 2. A rotating blade 4 is installed on the outer side of the rotating rod 3. The notch of the electroplating tank forms a plane, and a cover plate 5 is slidably installed on the upper side of the notch. The motor 1 is fixed to the cover plate 5, and the motor 1 is located on the upper side of the cover plate 5. The output end passes through the cover plate 5 and is connected to the rotating ring 2. By moving the cover plate 5 on the upper surface of the notch, the stirring position of the fixed-point stirring device can be changed, and the cover plate 5 can also prevent the overflow and waste of the electroplating solution.

[0039] In some other embodiments, the electroplating tank is made of a transparent material, and the position of the agglomerates can be observed with the naked eye, and then the cover plate 5 is manually controlled to slide. After sliding to the specified position, the stirring device is started. It should be noted that the electroplating tank can be used in conjunction with a vibration stirring device. Under its strong vibration, the agglomerates at the bottom of the tank are not easily aggregated.

[0040] In this embodiment, a limiting ring 6 is rotatably fitted on the outer side of the rotating rod 3. The limiting ring 6 can move vertically along with the rotating rod 3 but can rotate on the outer side of the rotating rod 3. Among them, three support rods 7 are fixed to the outer side of the limiting ring 6. The support rods 7 extend along the radial direction of the limiting ring 6, and multiple support rods 7 are evenly spaced along the circumferential direction of the limiting ring 6. The outer end of each support rod 7 is hinged with an arc-shaped housing 8, and a deflection control device 9 for controlling the deflection of the arc-shaped housing 8 is connected between the support rod 7 and the arc-shaped housing 8; the deflection control device 9 uses a micro motor 1, and both ends of the micro motor 1 are hinged to the support rod 7 and the arc-shaped housing 8 respectively, which can control the deflection of the arc-shaped housing 8 to open or close.

[0041] Specifically, when moving the fixed-point stirring device to a specified position, the deflection control device 9 controls the opening of the arc-shaped housing 8. After reaching the specified position, the deflection control device 9 controls the closing of the arc-shaped housing 8. By adopting the above method, it is convenient to reduce the fluid resistance during the movement of the device, avoid affecting the position of the agglomerates, and the closure after positioning can enhance the local stirring efficiency.

[0042] Multiple arc-shaped housings 8 can be combined to form a cylindrical limit cover with the rotating rod 3 as the axis, restricting the agglomerates of the high-temperature resistant material therein. The limit cover is located outside the rotating blade 4, which can limit the displacement of the agglomerates. By combining the physical constraint of the limit cover with the ultrasonic cavitation effect, the stubborn agglomerates can be decomposed more thoroughly.

[0043] In this embodiment, an arc-shaped limit guide rail 10 is fixed on the inner wall of the arc-shaped housing 8. A notch for the cooperation of the rotating blade 4 is formed inside the arc-shaped limit guide rail 10. A telescopic device 11 is fixed on the outer wall of the arc-shaped housing 8. The output end of the telescopic device 11 extends along the axial direction of the arc-shaped housing 8 and is connected to the arc-shaped limit guide rail 10. The arc-shaped limit guide rail 10 can be pushed to displace axially through the telescopic device 11. The rotating blade 4 and the rotating rod 3 are in frictional fit in the axial direction. The arc-shaped limit guide rail 10 can drive the rotating blade 4 to displace. By adjusting the position of the rotating blade 4 through the telescopic device 11, the dispersion requirements of agglomerates at different depths can be met. The axial frictional fit between the rotating blade 4 and the rotating rod 3 allows the blade to finely adjust its position under the drive of the limit ring 6 to avoid mechanical interference.

[0044] In this embodiment, a guide hole is opened at the lower end of the arc-shaped housing 8. A guide rod 12 is slidably installed in the guide hole. The guide rod 12 is fixedly connected with a magnetic seat 13. The magnetic seat 13 is connected to the arc-shaped housing 8 through an elastic connection device 14. An electromagnet 15 is installed at the bottom of the electroplating tank. After moving the fixed-point stirring device to the specified position, the electromagnet 15 is started. The electromagnet 15 attracts the magnetic seat 13, and the magnetic seat 13 can limit the circumferential direction of the arc-shaped housing 8. The cooperation between the electromagnet 15 and the magnetic seat 13 can quickly lock the position of the arc-shaped housing 8 to prevent it from shifting under stirring.

[0045] In this embodiment, a fixed blade 16 is connected in a mating manner to the outer side of the rotating rod 3, and a stopper 17 for restricting the rotation of the fixed blade 16 is installed on the inner side of the arc-shaped housing 8. The stopper 17 is a stopper rod. When the inner arc surface of the fixed blade 16 contacts the stopper 17, it stops under the blocking action of the stopper rod and does not rotate together with the rotating rod 3. Specifically, the rotating rod 3 includes an upper rod 18, a plug rod 19, and a lower rod 20. The plug rod 19 is fixedly connected to the upper rod 18, and the plug rod 19 is in plug-in fit with the lower rod 20; an inner sleeve 21 is connected to the outer side of the plug rod 19, and a plurality of relief grooves 22 are uniformly formed on the outer circumference of the inner sleeve 21. A clamping plate 23 is hinged in the relief groove 22, and a torsion reset device 24 is installed between the clamping plate 23 and the inner sleeve 21; an outer sleeve 25 is coaxially installed on the outer side of the inner sleeve 21, and a tooth 26 corresponding to the clamping plate 23 is formed on the inner wall of the outer sleeve 25, and the outer sleeve 25 is installed at the center of the fixed blade 16.

[0046] Initially, under the prestress of the torsion reset device 24, the outer end of the clamping plate 23 is in close contact with the tooth 26. After the rotating rod 3 rotates, the plug rod 19 of the rotating rod 3 drives the inner sleeve 21 to rotate, the inner sleeve 21 drives the clamping plate 23 to rotate, and the clamping plate 23 acts on the tooth 26 to drive the outer sleeve 25 to rotate counterclockwise. When the fixed blade 16 rotates to contact the stopper rod, the fixed blade 16 stops under the blocking action of the stopper rod, and the clamping plate 23 compresses the torsion reset device 24 under the reaction force of the tooth 26 and deflects in the relief groove 22, thereby making way for the tooth 26 and preventing the fixed blade 16 from interfering with the rotation of the inner sleeve 21. During the subsequent stirring process, the fixed blade 16 does not move, and the agglomerates are stirred by the combined action of the rotating blade 4 and the fixed blade 16.

[0047] In this embodiment, the rotating ring 2 is connected to the rotating rod 3 through an elastic spiral ring 27, and a fan blade 28 is simultaneously connected to the lower end of the rotating rod 3. The fan blade 28 can drive the flow of the electroplating solution in the vertical direction, which can achieve a better effect of stirring and dispersing.

[0048] The working principle and process of the fixed-point stirring device of the present invention application are as follows: After loading the required electroplating solution into the electroplating tank, prepare the required materials, close the cover plate 5 at the mouth of the electroplating tank, and start electroplating after starting the power supply. Initially, the arc-shaped housing 8 is in an open state, and the agglomeration position of the high-temperature resistant material is monitored in real time. When agglomerates are observed, the fixed-point stirring device is moved to the corresponding horizontal position of the agglomeration, and the deflection control device 9 controls the arc-shaped housing 8 to close. Multiple arc-shaped housings 8 can be combined to form a cylindrical limiting cover with the rotating rod 3 as the axis, restricting the agglomerates of the high-temperature resistant material therein. Subsequently, the telescopic device 11 is started to control the displacement of the arc-shaped limiting guide rail 10 and the rotating blade 4, so that at least one rotating blade 4 is adjacent to or in full contact with the agglomerates. Then, the electromagnet 15 is started, and the electromagnet 15 attracts the magnetic seat 13 to limit the circumference of the arc-shaped housing 8 through the electromagnet 15. Finally, the motor 1 is started, and the electroplating solution at this position is stirred through the fixed-point stirring device.

[0049] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
