Abstract

The present application relates to the technical field of optical element processing, in particular to a profiling polishing mechanism for special-shaped FA end face. It comprises a workbench, the top of which is fixed with a sealing cover; an annular track is fixed on the workbench, and an annular template groove is formed on the top of the annular track. The present application constructs an internal circulation gas path system integrating adsorption, chip removal and jet cleaning, and sets electromagnetic valves and industrial cameras to realize timing control of jet only when the hollow micro-porous polishing ball contacts the workpiece, which not only avoids the scattering of chips, but also ensures the stability of negative pressure in the sealing cover.

Description

Technical Field

[0001] This invention relates to the field of optical component processing technology, and more specifically to a contour polishing mechanism for irregularly shaped FA end faces. Background Technology

[0002] As a core component in optical communication systems, fiber optic arrays (FAs) are increasingly exhibiting complex end-face shapes, evolving from traditional planar surfaces to irregularly shaped structures such as inclined planes and curved surfaces. The surface quality of irregularly shaped FA end faces directly affects optical signal transmission efficiency, thus requiring extremely high polishing precision. Existing polishing equipment is mostly designed for planar workpieces and is ill-suited for the contour polishing needs of irregularly shaped end faces, resulting in problems such as uneven polishing and over-polishing of edges.

[0003] In the polishing process of irregularly shaped FA end faces, the removal of polishing debris is a key factor affecting surface quality. In traditional polishing equipment, debris easily adheres to the surface of the polishing tool and is carried to the workpiece surface during the polishing process, causing secondary scratches. At the same time, the accumulation of debris on the workpiece surface also reduces polishing efficiency and affects machining accuracy. How to effectively remove debris and keep the polishing tool clean during the polishing process is a problem that urgently needs to be solved in the current polishing technology of irregularly shaped FA end faces.

[0004] In the existing technology, although there are contour polishing devices that use mold grooves to achieve lifting and lowering, and polishing mechanisms that use gear transmission to achieve rotation, there is still no integrated solution that combines lifting, rotation and revolution combined motion with air jet timing control. This makes it difficult to synchronize the debris removal and polishing action during the polishing process, affecting the surface quality. Summary of the Invention

[0005] The purpose of this invention is to provide a contour polishing mechanism for irregularly shaped FA end faces, so as to solve the technical problem that polishing debris can easily cause secondary scratches in the prior art, and at the same time solve the technical problem that polishing tools are difficult to self-clean.

[0006] To achieve the above objectives, the present invention provides a contour polishing mechanism for irregularly shaped FA end faces, comprising a worktable with a sealing cover fixed to the top; an annular track fixed to the worktable, with an annular template groove on the top of the annular track; an adsorption seat located above the annular track, with a meshing collar fitted on the outer wall of the adsorption seat, the meshing collar meshing with a meshing toothed ring fixed to the inner wall of the sealing cover; a vertical tube rotatably mounted at the bottom of the adsorption seat, with an annular air hole on the tube wall, and a sliding contact fixed at the bottom end of the vertical tube and slidably mounted in the annular template groove; a drive assembly mounted below the worktable, the drive assembly being connected to the adsorption seat via a transmission component; an input end of an adsorption pump connected to the top of the adsorption seat via a pipeline, and an output end of the adsorption pump connected to a discharge pipe; at least one hollow microporous polishing ball mounted inside the sealing cover, the hollow channel of the hollow microporous polishing ball being connected to the discharge pipe via a jet hose.

[0007] Furthermore, an annular sleeve is fixedly installed at the top of the transmission component. The annular sleeve is fitted around the outer periphery of the vertical pipe, and the inner ring wall of the annular sleeve has a through hole that communicates with the annular air hole.

[0008] Furthermore, a solenoid valve is fixedly installed on the inner wall of the sealing cover. The input end of the solenoid valve is connected to the discharge pipe, and the output end of the solenoid valve is connected to the jet hose.

[0009] Furthermore, a sensor for detecting the contact state between the hollow microporous polishing ball and the workpiece is installed inside the sealing cover, and the sensor is electrically connected to the solenoid valve.

[0010] Furthermore, the sensor is an industrial camera that is fixedly mounted on the top of the inner cavity of the sealed cover.

[0011] Furthermore, a suction pipe, a suction connector, and a connecting pipe are sequentially connected between the input end of the adsorption pump and the top of the adsorption seat, and the connecting pipe is rotatably connected to the transmission component.

[0012] Furthermore, the drive assembly includes a servo motor fixedly mounted below the workbench, with a pinion connected to the output end of the servo motor, a large gear meshing with the pinion, and a square seat fixedly mounted on the top of the large gear; the transmission component is an L-shaped bend, with a square block fixed to the bottom end of the transmission component, and the square block is inserted into the square seat.

[0013] Furthermore, the hollow microporous polishing ball is driven to rotate by a micro motor, which is fixedly installed on the inner wall of the sealed cover.

[0014] Furthermore, there are multiple hollow microporous polishing balls, which are distributed along the circumferential direction of the adsorption seat; the number of jet hoses corresponds to the number of hollow microporous polishing balls, and each jet hose is connected to a corresponding solenoid valve.

[0015] Furthermore, a support frame is installed at the bottom of the workbench, and a control box is fixedly installed at the bottom of the workbench. The control box contains a controller, which is electrically connected to the servo motor, solenoid valve, industrial camera, and adsorption pump.

[0016] The present invention has the following beneficial effects: By sequentially connecting the adsorption pump, discharge pipe, jet hose and hollow microporous polishing ball, an internal circulation air circuit system integrating adsorption, chip removal and jet cleaning is constructed; on this basis, a solenoid valve and an industrial camera are further set to realize the timing control of jetting only when the hollow microporous polishing ball is in contact with the workpiece, which not only avoids chip dispersion, but also ensures stable negative pressure inside the sealed cover. Unlike conventional solutions that use separate vacuum pumps and air compressors, this solution employs a single adsorption pump to simultaneously provide both adsorption negative pressure and air jet positive pressure. The piping design automatically matches these pressures: the negative pressure generated at the pump's input is used for adsorption, fixation, and debris suction, while the positive pressure at the output is used for air jet cleaning. This design not only simplifies the system structure but also ensures a dynamic balance between adsorption and air jet cleaning—as the air jet volume increases, the suction volume at the adsorption end increases synchronously, maintaining a stable negative pressure within the sealed enclosure.

[0017] The vertical tube and the adsorption seat are raised and lowered by the cooperation of the annular template groove and the sliding contact. The adsorption seat rotates by the meshing transmission of the meshing toothed ring and the meshing collar. The workpiece is raised and lowered and rotated on the basis of the revolution driven by the drive component, forming a composite motion system. This system enables the sequential contact and differential removal of each point on the workpiece surface with the hollow microporous polishing ball, thus completing the imitation forming.

[0018] By combining the composite motion system with the air path timing control, a complete contouring-cleaning closed loop is formed: the debris generated during workpiece polishing is sucked into the suction port at the top of the suction seat, while the air jet on the surface of the hollow microporous polishing ball blows away the attached debris and then sucks it into the same suction port, so that the path of debris from generation to removal is minimized, avoiding secondary adhesion and ensuring the cleanliness of the polished surface.

[0019] This invention organically combines a lifting mechanism, a rotation mechanism, a revolution mechanism, and a pneumatic timing control mechanism to form a synergistic technical solution: lifting and rotation ensure contouring accuracy, revolution ensures full coverage, and pneumatic timing ensures synchronized cleaning. These features are interdependent and together solve the technical problem of secondary scratches from debris during the polishing of irregularly shaped FA end faces. The overall technical effect far exceeds the sum of the individual features. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] The present invention will be further described below with reference to embodiments.

[0025] Example 1: The following describes the embodiments of the present invention in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 7 As shown, the contour polishing mechanism for irregular FA end faces provided in this embodiment includes a worktable 1, an annular track 4, an adsorption seat 51, a vertical tube 53, a drive assembly, an adsorption pump 71, and a sealing cover 3.

[0027] The workbench 1 is a flat plate structure, with a support frame 11 installed at its bottom to support the entire device. A control box 2 is fixedly installed at the bottom of the workbench 1, housing a controller 21. A sealing cover 3, a transparent hemispherical cover, is fixedly installed at the center of the top of the workbench 1 for easy observation of the internal working conditions. The sealing cover 3 has an opening on its front, inside which a sealing door is fitted. A silicone frame strip is installed where the sealing door and the opening meet to ensure a tight seal. A handle 32 is installed on the front of the sealing door for easy opening and closing.

[0028] A meshing toothed ring 33 is fixedly installed on the inner wall of the sealing cover 3. Multiple industrial cameras 34 are fixedly installed on the top of the inner cavity of the sealing cover 3. The industrial cameras 34 use image recognition algorithms to determine the contact state between the workpiece and the hollow microporous polishing ball 76: when the gap between the workpiece surface and the polishing ball is less than a preset threshold (e.g., 0.1 mm) or when a change in reflectivity occurs on the workpiece surface, it is determined to be in contact. The controller 21 controls the opening and closing of the corresponding solenoid valve 35 in real time based on the output signals from the industrial cameras 34.

[0029] The annular track 4 is fixedly installed on the worktable 1 and is located inside the sealing cover 3. An annular template groove 41 is formed at the top of the annular track 4. The depth of the groove bottom varies continuously along the circumference, and its variation curve matches the target contour of the FA end face to be processed. Mounting lugs 42 are vertically fixed to the outer ring wall of the annular track 4. The mounting lugs 42 are detachably connected to the worktable 1 by screws, facilitating the replacement of annular tracks 4 with different contours.

[0030] The adsorption seat 51 is positioned above the annular track 4 and is used to adsorb and fix the workpiece. The top of the adsorption seat 51 has an adsorption port that matches the shape of the back of the workpiece. A meshing collar 52 is fixedly fitted onto the outer wall of the adsorption seat 51, and the meshing collar 52 meshes with a meshing toothed ring 33 on the inner wall of the sealing cover 3. When the adsorption seat 51 revolves, the meshing collar 52 rolls on the stationary meshing toothed ring 33, forcing the adsorption seat 51 to rotate.

[0031] The rotation mechanism in this design does not require an independent drive source. Instead, it passively generates rotation by the rolling motion of the meshing collar 52 on the fixed meshing gear ring 33 during the revolution of the adsorption seat 51. This design not only simplifies the structure but also ensures strict synchronization between rotation and revolution—the ratio of rotation speed to revolution speed is determined by the gear ratio, achieving stable composite motion without additional control. This is a key difference from conventional actively driven rotation mechanisms.

[0032] A vertical tube 53 is rotatably mounted on the bottom of the adsorption base 51, and can rotate freely relative to the adsorption base 51. An annular air hole 54 is formed through the wall of the vertical tube 53, surrounding it. A sliding contact 55 is vertically fixed to the bottom of the vertical tube 53, and is slidably mounted within an annular retaining groove 41. When the adsorption base 51 revolves, the sliding contact 55 slides within the annular retaining groove 41, and the undulating contour of the annular retaining groove 41 forces the sliding contact 55 and the vertical tube 53 to move up and down.

[0033] Unlike conventional contouring machining that relies solely on the template groove 41 for single lifting, this solution employs a synergistic lifting motion with revolution and rotation: revolution causes the workpiece to pass sequentially over the polishing balls, rotation causes the positions of various points on the workpiece surface to change continuously, and lifting ensures that points at different heights on the same workpiece surface contact the polishing balls at different times. All three work together to achieve contouring. The lifting mechanism is not isolated but a crucial component of the complex motion system.

[0034] The drive assembly is installed below the worktable 1 and is used to drive the adsorption seat 51 to revolve. The drive assembly includes a servo motor 61, a pinion 62, a gear 63, and a bracket 64. The servo motor 61 is fixedly installed at the top of the inner cavity of the control box 2, and its output end extends downward. The pinion 62 is fixedly installed at the output end of the servo motor 61. The gear 63 meshes with the pinion 62, and its bottom is rotatably mounted on the bracket 64 via a bearing. The bracket 64 is fixedly installed at the bottom of the control box 2. A connecting tube 65, which is a hollow tube, is vertically fixedly installed at the center of the bottom of the gear 63. A square seat 66 is fixedly installed on the top of the gear 63, and the square seat 66 is connected to the connecting tube 65.

[0035] The transmission component 67 is an L-shaped bend that passes through the center of the worktable 1 and can rotate relative to it. A square block 68 is fixedly installed at the bottom of the transmission component 67, and the square block 68 is inserted into the square seat 66 to achieve synchronous rotation between the transmission component 67 and the large gear 63. An annular sleeve 69 is fixedly installed at the top of the transmission component 67 and fits around the outer circumference of the vertical tube 53. A through hole 610 is opened in the inner wall of the annular sleeve 69, which is connected to the annular air hole 54 on the vertical tube 53. When the transmission component 67 rotates, it drives the annular sleeve 69 and the vertical tube 53 to revolve.

[0036] The adsorption pump 71 is fixedly installed at the bottom of the inner cavity of the control box 2. The adsorption pump 71 is used to generate negative pressure to adsorb workpieces and collect debris. The input end of the adsorption pump 71 is connected to a filter 78 via a suction pipe 72. The output end of the filter 78 is connected to a suction connector 73 via a pipe. The suction connector 73 is fixedly installed on a bracket 64, and a connecting pipe 65 is inserted into the suction connector 73 to form a rotatable sealed connection. The output end of the adsorption pump 71 is connected to a discharge pipe 74, which extends through the control box 2 and the workbench 1. The end of the discharge pipe 74 is fixed to a sealing cover 3 and connected to the input end of each solenoid valve 35.

[0037] Multiple micromotors 75 are fixedly installed on the inner wall of the sealing cover 3, and the micromotors 75 are distributed along the circumferential direction of the adsorption seat 51. Each micromotor 75 has a hollow microporous polishing ball 76 installed at its output end. The surface of the hollow microporous polishing ball 76 has evenly distributed air jet holes with a diameter of 0.1-0.3 mm, arranged in an array, with an adjacent hole spacing of 0.5-1 mm. The hollow microporous polishing ball 76 is fixedly connected to the output end of the micromotor 75 via a connecting tube. The connecting tube is hollow and communicates with the interior of the hollow microporous polishing ball 76. A connecting ring is fixedly installed at the end of the micromotor 75, and the connecting tube is fitted inside the connecting ring. An air jet hose 77 connects the connecting ring to the output end of the solenoid valve 35.

[0038] The controller 21 is installed inside the control box 2 and is electrically connected to the servo motor 61, solenoid valve 35, industrial camera 34, and adsorption pump 71. The controller 21 controls the opening and closing of the corresponding solenoid valve 35 based on the contact state between the polishing ball and the workpiece detected by the industrial camera 34.

[0039] The working process of this embodiment is as follows: First, open the sealed door and place the irregularly shaped FA end face workpiece to be processed on top of the adsorption seat 51, with the adsorption port of the adsorption seat 51 in contact with the back of the workpiece. Start the adsorption pump 71. The adsorption pump 71 passes through the suction pipe 72, suction connector 73, connecting pipe 65, transmission component 67, annular sleeve 69, through hole 610, annular air hole 54 on vertical pipe 53, and internal channel of vertical pipe 53, finally reaching the adsorption port at the top of the adsorption seat 51 to adsorb and fix the workpiece.

[0040] The servo motor 61 is started, which drives the pinion 62 to rotate. The pinion 62 drives the large gear 63 to rotate, and the large gear 63 drives the transmission component 67 to rotate through the square seat 66 and the square block 68. The transmission component 67 drives the annular sleeve 69 to rotate, and the annular sleeve 69 drives the vertical tube 53 and the adsorption seat 51 to revolve.

[0041] When the adsorption seat 51 revolves, the sliding contact 55 at the bottom of the vertical tube 53 slides within the annular template groove 41. The undulating contour of the annular template groove 41 forces the sliding contact 55 and the vertical tube 53 to move up and down. At the same time, the meshing collar 52 on the outer wall of the adsorption seat 51 rolls on the fixed meshing toothed ring 33, forcing the adsorption seat 51 to rotate.

[0042] The workpiece undergoes a complex motion of revolution, rotation, and lifting under the influence of the adsorption seat 51. Each micro-motor 75 is activated, driving the hollow microporous polishing ball 76 to rotate at high speed. When the workpiece rotates to the position of the hollow microporous polishing ball 76, it comes into contact with the ball, achieving polishing.

[0043] An industrial camera 34 monitors the contact status between the workpiece and the hollow microporous polishing ball 76 in real time. When a hollow microporous polishing ball 76 is detected to be in contact with the workpiece, the controller 21 controls the corresponding solenoid valve 35 to open. The gas discharged by the adsorption pump 71 enters the interior of the hollow microporous polishing ball 76 through the discharge pipe 74, the solenoid valve 35, and the jet hose 77, and is ejected from the micropores on the surface of the hollow microporous polishing ball 76, blowing away the debris adhering to the surface of the polishing ball.

[0044] The blown-off debris is drawn into the adsorption port at the top of the adsorption seat 51 by the airflow, and enters the filter 78 through the vertical pipe 53, annular sleeve 69, transmission component 67, connecting pipe 65, suction connector 73, and suction pipe 72. The debris is intercepted and collected by the filter element inside the filter 78, and the filtered clean gas is discharged through the adsorption pump 71, forming a cycle. The dust collection cover at the bottom of the filter 78 can be opened periodically to clean the collected debris.

[0045] After the workpiece is polished, turn off the servo motor 61 and the micro motor 75, close all solenoid valves 35, turn off the adsorption pump 71, open the sealing door, and remove the workpiece.

[0046] The key to this technical solution lies in using the gas discharged from the adsorption pump 71 as the air source for jet cleaning, and achieving jet cleaning only when in contact with the workpiece through the cooperation of the solenoid valve 35 and the industrial camera 34. This design is not a simple functional addition, but is based on an in-depth analysis of the characteristics of debris generation during the polishing process: debris is mainly generated during contact polishing, so jet cleaning only at this time can effectively clean while avoiding airflow disturbance from affecting negative pressure stability. When faced with the problem of debris adhesion, those skilled in the art usually use external air blowing or machine shutdown for cleaning, and would hardly think of introducing the exhaust gas from the adsorption pump into the polishing ball and achieving contact-based timing control.

[0047] Example 2 This embodiment is basically the same as embodiment 1, except that the installation method of the annular track 4 and the control method of the hollow microporous polishing ball 76 are different.

[0048] In Embodiment 1, the annular track 4 is connected to the worktable 1 by screws via mounting lugs 42. Alternatively, the annular track 4 can be magnetically attached to the worktable 1, with an electromagnet embedded in a corresponding position on the worktable 1. The annular track 4 can be quickly replaced by switching the electromagnet on and off. This solution is suitable for production scenarios requiring frequent track replacement.

[0049] In Example 1, an industrial camera 34 is used to detect the contact state between the hollow microporous polishing ball 76 and the workpiece. Alternatively, a torque sensor can be installed on the drive shaft of the micro motor 75 to determine whether the polishing ball is in contact with the workpiece by detecting changes in the motor torque. When the polishing ball contacts the workpiece, the torque increases, and the controller 21 controls the solenoid valve 35 to open based on the torque signal. This solution is suitable for applications sensitive to optical detection.

[0050] In Example 1, a single adsorption pump 71 simultaneously provides both adsorption negative pressure and air jet source. Alternatively, a separate vacuum pump and air compressor can be used; the vacuum pump is used for workpiece adsorption and debris collection, while the air compressor is used for air jet cleaning of the hollow microporous polishing balls 76. The two air circuit systems operate independently, facilitating separate adjustment of pressure parameters.

[0051] In Example 1, the hollow microporous polishing ball 76 is directly driven by a micro motor 75. As an alternative, a flexible shaft drive can be used, in which the motor is mounted outside the sealing cover 3, and the power is transmitted to the polishing ball inside the sealing cover 3 through the flexible shaft, thereby reducing the heat generation inside the sealing cover 3.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
