Description

Technical Field

[0001] This invention relates to the field of ceramic ferrule testing technology, specifically to an automated concentricity probe testing device for ceramic ferrules. Background Technology

[0002] The automated concentricity probe testing device for ceramic ferrules is a specialized device for automatic and high-precision measurement and sorting of the concentricity (eccentricity) of the inner hole, outer circle, and key positions of fiber optic ceramic ferrules (core components of fiber optic connectors). Its core testing process relies on probe testing technology, which collects displacement signals by contacting the end contour of the object under test with the probe. Combined with an automated mechanism, it realizes unmanned operation of the entire process of feeding, positioning, rotation, testing, data processing, and sorting. It is widely used in the batch quality inspection process of optical communication device manufacturing.

[0003] When testing ceramic ferrules of special specifications, or when the probe rod must be designed to be thin and long due to mechanical avoidance requirements, even if the spindle speed is not high, the probe, being a cantilever beam structure, has an inherent mechanical frequency. During the automated rotation of the ceramic ferrule, if the rotation frequency of the ceramic ferrule is close to the vibration frequency of the probe support, resonance will occur, causing false ripples in the measurement results and distorting the accuracy of the measurement data. Existing technology uses particle dampers to solve this problem by designing a tiny cavity inside the probe rod and filling it with fine tungsten particles. When resonance occurs, the friction and impact between powder or ceramic microspheres will generate nonlinear damping, which will greatly suppress the amplitude. However, when the rotation frequency of the ceramic core reaches a certain critical point, the tungsten powder inside the particle damper will undergo collective displacement and aggregation when the vibration frequency changes. This aggregation changes the mass distribution (center of gravity position) of the probe arm. For a precision spindle, even if the center of gravity shifts by only a few micrometers, it will introduce a new eccentric torque, induce dynamic imbalance error that is strongly correlated with the rotational speed, and ultimately lead to a lack of consistency in the concentricity data measured at different rotational speeds, making it impossible to verify each other.

[0004] To address this, an automated concentricity probe detection device for ceramic ferrules is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an automated concentricity probe detection device for ceramic ferrules. During the downward movement of the probe test needle, a transmission component synchronously drives an auxiliary support component to slide forward and rise slightly, providing support and resistance to the middle section of the probe test needle. Simultaneously, a partition plate divides the inner cavity of the particle damper on the long probe into several independent chambers. This solves the problems of inconsistency and distortion in concentricity measurement data at different rotational speeds when detecting long ceramic ferrules. Specifically, the slender probe, due to its cantilever beam structure, easily resonates with the rotational frequency of the ceramic ferrule. Furthermore, existing particle dampers tend to aggregate with changes in vibration frequency, altering the probe's center of gravity and causing dynamic imbalance errors. This effectively suppresses probe resonance, prevents particle aggregation and displacement of the probe's center of gravity, and ensures the accuracy of concentricity detection for long ceramic ferrules at different rotational speeds.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automated concentricity probe testing device for ceramic ferrules includes a worktable, a drive base, and a vertical cantilever. It also includes a fixed rod, a vertical moving base, a transmission base, a transmission assembly, a probe testing assembly, and an auxiliary support assembly. The fixed rod is fixed inside the vertical cantilever. The vertical moving base is disposed inside the vertical cantilever and slidably sleeved on the surface of the fixed rod. The transmission base is fixed on the surface of the vertical moving base. The transmission assembly is installed inside the transmission base. The probe testing assembly is installed at the top of the transmission assembly. The auxiliary support assembly is located at the top of the transmission assembly and below the probe testing assembly. When the vertical moving base is driven downwards, it simultaneously drives the transmission assembly to extend forward. When the transmission assembly extends forward, it simultaneously drives the auxiliary support assembly to slide forward. Simultaneously, the auxiliary support assembly slides forward and extends upwards, supporting the bottom middle section of the probe testing assembly.

[0007] Preferably, the transmission assembly includes a base, a lead screw, and a transmission rod. The base is disposed inside the front end of the transmission seat, the lead screw is disposed inside the transmission seat and its rear end extends to the rear end of the transmission seat, and the transmission rod is fixed to the rear end surface of the base and is threadedly connected to the front end of the lead screw.

[0008] Preferably, the transmission base has symmetrically fixed limit seats on both sides of the front end, and the base has symmetrically fixed limit rods that pass through the interior of the limit seats on both sides, and the limit rods are slidably connected to the limit seats.

[0009] Preferably, the rear end of the transmission seat is provided with a fixed gear that is fixedly connected to the lead screw, the surface of the vertical moving seat is provided with a through groove, the inside of the through groove is rotatably connected to a drive gear, the surface of the fixed rod is provided with a rack, the drive gear is meshed with the rack, the rear end of the transmission seat is rotatably connected to a transmission gear, the transmission gear is located between the drive gear and the fixed gear, and it is meshed with both the drive gear and the fixed gear.

[0010] Preferably, the probe testing assembly includes a support base, a particle damper, and a probe test needle. The support base is fixed to the top of the transmission base, the particle damper is fixed to the front end of the support base, and the probe test needle is fixed to the front end of the particle damper.

[0011] Preferably, the particle damper has several partition plates fixedly arranged inside along its axial direction. The partition plates are separated from the inside of the particle damper to form several independent cavities, and several spherical particles are evenly distributed in each independent cavity. When the spherical particles are subjected to resonance, they undergo irregular friction and impact motion in the corresponding independent cavity to attenuate the vibration amplitude.

[0012] Preferably, the auxiliary support assembly includes a fixed plate, a support plate, a crossbeam, an inclined sliding groove, and an inclined support rod. The fixed plate is fixed to the top of the base, the support plate is disposed at the top of the fixed plate, the crossbeam is fixed inside the transmission seat and is located above the transmission rod, the inclined sliding groove is symmetrically opened on both sides of the support plate, and the inclined support rod is symmetrically fixed to the front end of the crossbeam and is slidably connected to the inclined sliding groove.

[0013] Preferably, the fixed plate has symmetrical openings on both sides of the lifting groove, and the bottom end of the support plate is symmetrically fixed with lifting rods adapted to the lifting grooves, and the lifting rods are slidably connected to the lifting grooves.

[0014] Preferably, the spherical particles are made of high-density ceramic microspheres and have a mixed particle size distribution.

[0015] Preferably, each independent cavity formed by the partition plate is filled with high-viscosity dimethicone oil, and the high-viscosity dimethicone oil fills the gaps between the spherical particles.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, when the concentricity of a long ceramic ferrule is detected by a slender probe, the vertical moving seat drives the probe testing assembly to descend, and simultaneously drives the transmission assembly to move horizontally along the axial direction. At the same time as the transmission assembly moves horizontally, it also drives the auxiliary support assembly to slide and rise synchronously, so that the auxiliary support assembly moves to the middle section of the probe testing assembly to form a fulcrum. This provides auxiliary support for the probe testing assembly, thereby canceling the resonance generated when the probe testing assembly contacts the ceramic ferrule, thus ensuring the accuracy of the concentricity detection of the long ceramic ferrule.

[0017] 2. Through the configuration of a lead screw, transmission rod, fixed gear, drive gear, rack, transmission gear, inclined sliding groove, inclined support rod, and support plate, during the downward movement of the vertical moving seat, the drive gear meshes with the rack. When the drive gear rotates, it sequentially drives the transmission gear and fixed gear to rotate synchronously. The rotation of the fixed gear drives the lead screw to rotate, thereby extending the transmission rod outward. Simultaneously, it drives the inclined sliding groove on the support plate to slide along the axis of the inclined support rod, thereby driving the support plate to slide forward and rise. This causes the support plate to contact the middle section of the probe test needle, thus counteracting the "head-down" deflection caused by the weight of the long probe. This ensures that the probe test needle always contacts the ceramic ferrule in a horizontal posture closest to the axis, significantly improving the reference accuracy of concentricity measurement.

[0018] 3. By setting a partition plate and spherical particles inside the particle damper, the partition plate divides the large chamber into multiple independent units, causing the spherical particles to gather to one side under micro-vibration. The displacement is also limited within the millimeter-level partition plate grid, ensuring that the mass distribution (center of gravity position) of the long probe cantilever beam remains highly stable at different rotation frequencies. This solves the problem of inconsistent concentricity detection data at different rotation speeds. When the ceramic ferrule rotates at high speed and contacts the probe resonance, the spherical particles in the chamber dissipate energy through countless inelastic collisions (beads hitting the partition plate) and micro-friction (beads squeezing each other), instantly suppressing the probe amplitude to the sub-micron level. This eliminates false ripples mixed in with the measurement results, improves the authenticity of the data, and greatly enhances the detection efficiency of automated production lines.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 8 This invention provides an automated concentricity probe detection device for ceramic ferrules, the technical solution of which is as follows: Reference Figure 1 , Figure 2 and Figure 3An automated concentricity probe testing device for ceramic ferrules includes a worktable 1, a drive base 2, and a vertical cantilever 3. The drive base 2 is fixed to the top of the worktable 1, and the vertical cantilever 3 is slidably connected to the top of the drive base 2. It also includes a fixed rod 4, a vertical moving base 5, a transmission base 6, a transmission assembly 7, a probe testing assembly 8, and an auxiliary support assembly 9. The fixed rod 4 is fixed inside the vertical cantilever 3, allowing the vertical moving base 5 to move up and down along the axis of the fixed rod 4. The vertical moving base 5 is located inside the vertical cantilever 3 and is used to drive the entire probe to move, enabling the probe test needle 83 to accurately contact and test the ceramic ferrule to be tested. The probe test needle 83 is slidably fitted onto the surface of the fixed rod 4. The transmission base 6 is fixed to the surface of the vertical moving base 5 and serves as the base for mounting the transmission assembly 7, the probe testing assembly 8, and the auxiliary support assembly 9. The transmission assembly 7 is installed inside the transmission base 6. When seat 5 moves downward, it simultaneously drives transmission component 7 to extend forward, thereby converting the vertical downward movement of vertical moving seat 5 into horizontal forward movement of transmission component 7. Probe test component 8 is installed at the top of transmission component 7 to facilitate contact with ceramic insert for testing. Auxiliary support component 9 is located at the top of transmission component 7. When transmission component 7 moves horizontally forward, it simultaneously drives auxiliary support component 9 to slide forward with it. During the sliding process, auxiliary support component 9 extends upward and finally abuts against the bottom of the middle section of probe test component 8, forming a stable support. It is located below probe test component 8. When vertical moving seat 5 is driven downward, it simultaneously drives transmission component 7 to extend forward. When transmission component 7 extends forward, it simultaneously drives auxiliary support component 9 to slide forward. As auxiliary support component 9 slides forward, it extends upward and supports the bottom of the middle section of probe test component 8.

[0023] Reference Figure 3 and Figure 6 In one embodiment of the present invention, the transmission assembly 7 specifically includes a base 71, a lead screw 72, and a transmission rod 73. The base 71 is disposed at the front end of the transmission seat 6, the lead screw 72 is disposed inside the transmission seat 6 and its rear end extends to the rear end of the transmission seat 6, and the transmission rod 73 is fixed to the rear end surface of the base 71 and is threadedly connected to the front end of the lead screw 72. When the lead screw 72 rotates, it forms a helical transmission engagement with the transmission rod 73, thereby driving the transmission rod 73 to synchronously drive the base 71 to move forward, so that the base 71 extends outward from the inside of the transmission seat 6.

[0024] Reference Figure 7In one embodiment of the present invention, specifically, limiting seats 711 are symmetrically fixed on both sides of the front end of the transmission seat 6. Limiting rods 712 that pass through the interior of the limiting seats 711 are symmetrically fixed on both sides of the base 71. The limiting rods 712 are slidably connected to the limiting seats 711. As the base 71 extends outward from the interior of the transmission seat 6, the limiting rods 712 are simultaneously driven to slide along the interior of the limiting seats 711. The sliding cooperation between the limiting rods 712 and the limiting seats 711 limits the movement trajectory of the base 71 in the circumferential direction, effectively preventing the base 71 from swaying or deviating, and achieving precise guidance for the horizontal movement of the base 71.

[0025] Reference Figure 3 and Figure 5 In one embodiment of the present invention, specifically, the rear end of the transmission seat 6 is provided with a fixed gear 721 fixedly connected to the lead screw 72. A through groove 722 is provided through the surface of the vertical moving seat 5, and a drive gear 723 is rotatably connected inside the through groove 722. A rack 724 is provided on the surface of the fixed rod 4. Since the rack 724 is fixed to the outer wall of the fixed rod 4, when the vertical moving seat 5 moves downward, it synchronously drives the drive gear 723 on its surface to mesh with the rack 724. Under the meshing action, the drive gear 723 rolls along the rack 724 and rotates synchronously in the through groove 722. The drive gear 723 and the rack 724 are meshed and connected. A transmission gear 725 is rotatably connected to the rear end of the transmission seat 6. The transmission gear 725 is located between the drive gear 723 and the fixed gear. Between gears 721, and meshing with drive gear 723 and fixed gear 721, drive gear 723 meshes with transmission gear 725, and transmission gear 725 meshes with fixed gear 721; when drive gear 723 rotates, it sequentially drives transmission gear 725 and fixed gear 721 to rotate synchronously, and through the rotation of fixed gear 721, it drives lead screw 72 to rotate around its own axis. This three-stage gear meshing transmission structure can accurately realize the conversion from vertical movement to rotational movement. By matching the gear ratio, it can adapt the speed and amplify the torque, while realizing power reversal, making the structural layout more compact; rigid meshing transmission has no slippage or looseness problems, ensuring the smoothness of lead screw 72 rotation and transmission synchronization, thereby improving the accuracy of subsequent component movement and adapting to the high-frequency linkage requirements of equipment.

[0026] Reference Figure 2 and Figure 3As one embodiment of the present invention, specifically, the probe testing assembly 8 includes a support base 81, a particle damper 82, and a probe testing needle 83. The support base 81 is fixed to the top of the transmission base 6. The support base 81 integrally fixes the particle damper 82 and the probe testing needle 83 at its end to the upper part of the transmission base 6, realizing the integrated fixation of the particle damper 82 and the probe testing needle 83, ensuring the coaxiality of the installation, improving the stability of detection and vibration suppression, and simplifying assembly and saving layout space. The particle damper 82 is fixed to the front end of the support base 81. When the probe testing needle 83 contacts the high-speed rotating ceramic ferrule and generates resonance, the particle damper 82 can immediately dampen and suppress the resonance. The probe testing needle 83 is fixed to the front end of the particle damper 82 to facilitate contact with the ceramic ferrule for concentricity detection.

[0027] Reference Figure 8 As one embodiment of the present invention, specifically, a plurality of partition plates 811 are fixedly provided inside the particle damper 82 along its axial direction. The partition plates 811 and the particle damper 82 are separated to form a plurality of independent cavities, and a plurality of spherical particles 812 are evenly distributed in each independent cavity. When the spherical particles 812 are resonant, they perform irregular friction and impact movements in the corresponding independent cavity to attenuate the vibration amplitude. The partition plates 811 separate the independent cavities, restricting the large-range displacement of the spherical particles 812 and preventing the spherical particles 812 from aggregating and causing the center of gravity of the probe test needle 83 to shift. The spherical particles 812 perform friction and impact movements in the cavity with the resonance, rapidly attenuating the vibration amplitude and ensuring the accuracy of the detection. At the same time, the multi-cavity distributed damping makes the vibration suppression effect more uniform and stable.

[0028] Reference Figure 3 , Figure 4 and Figure 6In one embodiment of the present invention, the auxiliary support assembly 9 specifically includes a fixed plate 91, a support plate 92, a crossbeam 93, an inclined sliding groove 94, and an inclined support rod 95. The fixed plate 91 is fixed to the top of the base 71, and the support plate 92 is disposed at the top of the fixed plate 91. A semi-circular groove is formed at the top of the support plate 92. During the process of moving forward and rising with the base 71, the semi-circular groove abuts against the bottom end of the middle section of the probe test needle 83, providing a slight upward lifting force for the probe test needle 83, offsetting the downward deflection of the long probe due to its own weight, and ensuring that the probe test needle 83 contacts the ceramic ferrule in a horizontal posture that conforms to the theoretical axis. Significantly improving the benchmark accuracy of concentricity measurement, the crossbeam 93 is fixed inside the transmission seat 6 and located above the transmission rod 73, providing a fixed installation position for the inclined support rod 95, ensuring that the inclined sliding groove 94 slides along the axis of the inclined support rod 95, thereby driving the support plate 92 to slide forward and rise, so as to play a fixed axis guide to prevent the support plate 92 from deviating during the movement, ensuring that the sliding and rising action of the support plate 92 is accurate and stable, and improving the reliability of lifting and positioning. The inclined sliding groove 94 is symmetrically opened on both sides of the support plate 92, and the inclined support rod 95 is symmetrically fixed at the front end of the crossbeam 93, and it is slidably connected to the inclined sliding groove 94.

[0029] Reference Figure 4 and Figure 6 In one embodiment of the present invention, specifically, the two sides of the fixed plate 91 are symmetrically opened in the lifting groove 911, and the bottom end of the support plate 92 is symmetrically fixed with lifting rods 921 adapted to the lifting groove 911. The lifting rods 921 are slidably connected to the lifting groove 911. Through the symmetrical sliding cooperation between the lifting rods 921 and the lifting groove 911, the lifting movement of the support plate 92 is oriented and guided, limiting its horizontal deviation, ensuring the stability and coaxiality of the lifting movement of the support plate 92, and improving the accuracy of lifting and positioning the probe test needle 83.

[0030] Reference Figure 8 As one embodiment of the present invention, specifically, the spherical particles 812 are made of high-density ceramic microspheres. The high-density ceramic microspheres improve the impact damping effect and quickly dissipate the resonant energy. In addition, they adopt a mixed particle size setting, which makes the mixed particle size filling more dense, eliminates independent cavity gaps, and makes the vibration suppression more uniform and stable, adapting to the suppression requirements of different frequency resonances.

[0031] Reference Figure 8In one embodiment of the present invention, each independent cavity formed by the partition plate 811 is filled with high-viscosity dimethyl silicone oil, and the high-viscosity dimethyl silicone oil fills the gaps between the spherical particles 812. The silicone oil fills the gaps between the spherical particles 812, improves the density of the damping medium, and dissipates vibration energy in multiple dimensions through viscous damping and impact damping of the spherical particles 812, thereby enhancing the broadband vibration suppression effect. At the same time, the silicone oil coats the spherical particles 812, reduces impact wear, improves the service life of the damper, and also prevents the spherical particles 812 from shifting, thus ensuring vibration suppression stability.

[0032] Working principle: When the ceramic ferrule is sent to the testing area on the worktable 1 to await testing, the drive seat 2 first drives the vertical moving seat 5 on the surface of the vertical cantilever 3 to move downward on the surface of the fixed rod 4. During the downward movement of the vertical moving seat 5, the transmission component 7 inside the transmission seat 6 is simultaneously extended forward. At the same time, during the forward extension of the transmission component 7, the auxiliary support component 9 is simultaneously slid forward and extended upward. After the vertical moving seat 5 moves to the appropriate position, it stops moving downward. At this time, the extension position of the transmission component 7 is fixed, and the position of the auxiliary support component 9 is also fixed. The top of the auxiliary support component 9 is in contact with the bottom of the middle section of the probe test component 8 to provide auxiliary support. Then, the drive seat 2 drives the vertical cantilever 3 to move forward as a whole to contact the ceramic ferrule in the testing area for concentricity testing.

[0033] Specifically, when the vertical moving seat 5 is driven to move downward on the surface of the fixed rod 4, it simultaneously drives the drive gear 723 inside the through groove 722 to mesh and rotate with the rack 724. The through groove 722, through the transmission gear 725, drives the fixed gear 721 to rotate. As the fixed gear 721 rotates, it drives the lead screw 72 to rotate inside the transmission seat 6. At this time, by engaging the lead screw 72 inside the transmission rod 73, the transmission rod 73 can be pushed outward along the axis of the lead screw 72. This allows the transmission rod 73 to drive the base 71 to move forward from inside the transmission seat 6, while simultaneously causing the limiting rod 712 to slide inside the limiting seat 711, serving as a guide for movement. During the movement of the base 71, the support plate 92 above it slides forward on the surface of the inclined support rod 95 through the inclined sliding groove 94. While sliding, the support plate 92 moves upward on the top of the fixed plate 91, and at the same time, the lifting rod 921 slides upward inside the lifting groove 911 to guide the movement. Finally, the support plate 92 extends and fits against the middle section of the probe test needle 83. Then, the probe test needle 83 contacts the high-speed rotating ceramic ferrule to be tested for detection. At the same time, when resonance occurs, the spherical particles 812 placed in the independent cavity formed by the partition plate 811 can stabilize the center of the probe test needle 83 during resonance.
