Fig. 1 shows the configuration of an exemplary grinding assembly 10 (an assembly comprising a grinding base 4, a grinding disc arrangement 5 and a grinding jig 6). The polishing assembly 10 can be used for fully automated fiber optic connector polishing. In fig. 1, a connector holder 21 is fixed to the connector carrier 2. The connector clamp 21 includes a plug retention strip 22 for retaining plugs of a batch of fiber optic connectors. The plug fixing strip 22 is provided with a plurality of plug through holes corresponding to the plugs of the optical fiber connectors, and the plug fixing strip 22 is provided with a plug pressing device which is pressed and held after plug-in mounting, so that the plugs of the optical fiber connectors are clamped and fixed. The structural arrangement of the plug strip 22 is well known to those skilled in the art and will not be described in detail herein.

Generally, the plug clip of the optical fiber connector is fixed in the plug fixing strip 22, and the plug fixing strip 22 is mounted to the connector carrier 2, for example, in fig. 1, the plug fixing strip 22 can be mounted to the connector carrier 2 by using a magnetic attraction device 23. The grinding assembly 10 can be used to grind the bottom end face of an optical fiber cord in an optical fiber connector that is clamped in the plug retention strip 22.

The grinding assembly 10 includes a grinding base 4, a grinding disc device 5 and a grinding jig 6. The polishing disc device 5 is attached to the polishing base 4 and polishes the bottom end surface of the optical fiber in the optical fiber connector. A grinding jig 6 is also mounted on the grinding base 4. Referring to fig. 1, in a polishing unit 10, a polishing disc device 5 is mounted on a polishing base 4, and a polishing jig 6 is provided on the polishing base 4 at the polishing disc device 5.

The grinding jig 6 includes two fixed bar carriers 61. Two fixed bar carriers 61 are relatively fixedly arranged on both sides of the grinding disc device 5. Referring to fig. 1, the plug strip 22 has a longitudinal direction L1 and a width direction W1, and two strip stages 61 are fixedly provided on both sides of the polishing disc device 5 along the longitudinal direction L1 of the plug strip 22.

The grinding jig 6 further comprises a fixed clamp block 62, a movable clamp block 63 and a clamp applicator 64. The fixed clamp block 62 is provided on one of the fixed bar stages 61 (the fixed bar stage 61 on the right in fig. 1) of the two fixed bar stages 61, and the movable clamp block 63 is movably mounted on the other fixed bar stage 61 (the fixed bar stage 61 on the left in fig. 1) of the two fixed bar stages 61 in the lateral direction. The clamping force applicator 64 is used for driving the movable clamping block 63 to move towards the fixed clamping block 62, so as to form clamping on the plug fixing strip 22. Referring to fig. 1, a fixed clamping block 62 is arranged on one of the fixed strip carriers 61, and a movable clamping block 63 is slidably mounted on the other fixed strip carrier 61 in the transverse direction, specifically, the movable clamping block 63 is slidably mounted on the other fixed strip carrier 61 along the length direction L1 of the plug fixed strip 22. A clamping force applicator 64 is arranged between the movable clamping block 63 and the grinding base 4, wherein the clamping force applicator 64 can be realized by an electric cylinder or an air cylinder, a hydraulic cylinder and the like. For example, the clamping force applicator 64 may be fixed to the grinding base 4, and the output shaft outputting the linear motion is connected to the movable clamping block 63, so as to drive the movable clamping block 63 to move along the length direction L1 of the fixed plug strip 22, and further move closer to or away from the fixed clamping block 62, so as to clamp or release the two ends of the fixed plug strip 22 along the length direction L1. The fixed clamping block 62 can be matched with the movable clamping block 63 to realize clamping action on one hand, and can be used for positioning after clamping on the other hand, so that the optical fiber connector after clamping cannot obviously deviate, and the effective grinding of the optical fiber connector is ensured.

In the illustrated embodiment, the grinding fixture 6 may further include a corner crimping cylinder 66. The corner holding cylinder 66 may be provided on the polishing base 4 corresponding to each fixed bar stage 61. Referring to fig. 4, the polishing base 4 is provided with corner holding cylinders 66 corresponding to the respective fixing bar stages 61, and specifically, a corner holding cylinder 66 may be provided on one side of the corresponding fixing bar stage 61 in the width direction W1 (of the plug fixing bar 22). In the illustrated polishing jig 6, the corner holding cylinders 66 (both corner holding cylinders 66) may be located on the same side of the retainer bar stage 61 in the width direction W1 of the plug retainer bar 22, which makes it possible to reduce the size of the polishing jig 6 in the width direction W1.

Referring to fig. 2 and 4, a pressing arm 67 may be fixed to an end (an upper end in fig. 2) of a piston rod 66a of the corner pressing cylinder 66, and a pressing block 68 may be provided at an end of the pressing arm 67. A pressing buffer elastic element 69 is arranged between the pressing block 68 and the end of the pressing arm 67 for pressing the plug fixing strip 22. The angular holding cylinder 66 may be realized by, for example, an electric cylinder, or an air cylinder, a hydraulic cylinder, etc., and the piston rod 66a thereof is also an output shaft for outputting motion thereof, and preferably, the angular holding cylinder 66 may be realized by a 90-degree press-down clamping rotary air cylinder which can realize press-down after rotation of the piston rod 66 a. The corner pressure cylinder 66, the pressure arm 67, the pressure block 68, the pressure buffer elastic member 69 and the like can jointly form a pressure holding component. The pressing and holding buffer elastic member 69 may be, for example, a pressing and holding buffer spring, and by providing the pressing and holding buffer spring, after the piston rod 66a of the 90-degree pressing and clamping rotary cylinder serving as the corner pressing and holding cylinder 66 is rotated and pressed down, the pressing and holding buffer spring is compressed, so as to provide a pressing force for pressing down the plug fixing strip 22, and the setting of the pressing and holding buffer spring is also adapted to slight vertical jumping of the plug fixing strip 22 during grinding, and by setting different spring forces of the pressing and holding buffer spring, optical fiber connectors with different technical requirements can be ground by matching with the grinding disc device 5, thereby conveniently meeting the grinding requirements of different customers. The holding block 68 may be a buffer limit screw, and the material of the top of the screw head may be polyurethane, so as to avoid hard contact with the plug strip 22. In practical use, the piston rod 66a can rotate by a predetermined angle with the pressure arm 67 by providing a driving force through the corner pressure cylinder 66, so that the pressure block 68 is located above the plug fixing strip 22, and thus when the plug fixing strip 22 slightly bounces up and down during grinding, the elastic force formed after the pressure buffer elastic member 69 is compressed can enable the pressure block 68 to press and hold the plug fixing strip 22 downwards against the grinding disc device 5.

In the polishing assembly 10, the movable clamping block 63 is driven by the clamping force applicator 64 to move towards the fixed clamping block 62, so that the two ends of the plug fixing strip 22 in the length direction L1 can be tightly clamped, and then the corner pressing cylinder 66 is matched to drive the pressing arm 67 to rotate to enable the pressing block 68 to press and hold the two ends of the plug fixing strip 22 in the length direction L1 downwards by abutting against the polishing disc device 5 through the elastic force of the pressing and holding buffer elastic piece 69, so that the convenient, efficient and reliable clamping and dismounting of the optical fiber connector during polishing treatment can be realized.

In the illustrated embodiment, the grinding fixture 6 may further include an end baffle 65. End stops 65 are located on the grinding bed 4 at the fixed and movable clamping blocks 62, 63 for centering the plug fastening strip 22 in the width direction W1. Referring to fig. 1, end side baffles 65 are respectively disposed on the grinding base 4 at the fixed clamping block 62 and the movable clamping block 63, specifically, the end side baffles 65 may be disposed at two sides of the fixed clamping block 62 and/or the movable clamping block 63 along the width direction W1, so that the centering limit of the plug fixing strip 22 in the width direction W1 may be achieved, and the centering limit cooperates with the clamping action of the fixed clamping block 62 and the movable clamping block 63, so that the optical fiber connector clamped and fixed may not significantly deviate in the horizontal plane.

It is to be understood that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims. Further, the conversion methods in the different embodiments may be appropriately combined.

Fig. 5 is a partially enlarged view of a portion a in fig. 4. In the embodiment shown in fig. 5, both ends of the plug fixing strip 22 in the length direction L1 may be provided with V-shaped notches 221. Correspondingly, the fixed clamp block 62 and the movable clamp block 63 may be provided with a tip structure 621 engaged with the V-shaped notch 221. This allows a better clamping positioning of the plug strip 22.

Referring to fig. 6, the grinding assembly 10 may further include a count sensor 9 for counting the number of rotations of the grinding pad in the grinding disc arrangement 5. The counter sensor 9 may be provided on the grinding bed 4. The polishing pad in the polishing pad device 5 has a certain service life, the number of times of finishing the internal control program can be increased every time the polishing is finished, and the pad changing program is started after the current polishing pad finishes the preset limit number of times. The home position sensor may perform a home position returning action, and the position after the home position returning action is completed may be a reference position provided for the polishing disc device 5 to be used for positioning a subsequent pad changing apparatus. And when the return to the original point is finished, the pad replacing equipment is operated.

The configuration of an exemplary abrasive disc device 5 is shown in fig. 7 to 9.

Referring to fig. 7 and 9, the grinding disc device 5 may include a grinding center shaft 51, a rotation driven gear 52, and a rotation driving device 53. Wherein the grinding central shaft 51 can be vertically mounted on the grinding base 4. The rotation driven gear 52 may be rotatably mounted on the grinding center shaft 51, and may be fitted around the grinding center shaft 51 via a rotary bearing 59, for example. A rotation driving means 53 may be provided on the grinding bed 4 for driving the rotation driven gear 52 to rotate. Preferably, the rotary bearing 59 may be a flat bearing such as a flat needle bearing, which may ensure flatness of the rotation driven gear 52, may also transfer the load of the entire grinding disc device 5 from the motor spindle to the flat bearing, and may prevent the rotation driven gear from rubbing against the lower mounting block.

The grinding disc device 5 may further comprise at least three revolution oscillation transmission wheels 54 and a revolution oscillation drive device 55. At least three revolution swing transmission wheels 54 may be respectively rotatably installed on the rotation driven gear 52. An eccentrically disposed revolving swing pin 56 is fixedly attached to each revolving swing transmission wheel 54, wherein at least one revolving swing transmission wheel 54, such as 54a, has its rotation axis geared with the grinding center shaft 51, as shown at B1 in fig. 9. The revolution pendulum driving device 55 can drive the grinding center shaft 51 to rotate. A synchronous toggle connecting disc 57 is connected between the revolution swing toggle pins 56, and toggle pin sleeving holes corresponding to the revolution swing toggle pins 56 are formed in the synchronous toggle connecting disc 57. The top ends of the revolving swing toggle pins 56 are commonly connected to a grinding disc holder 58, and the revolving swing toggle pins 56 are rotatably connected to the grinding disc holder 58. The polishing pad base 58 is provided with a polishing pad for polishing the bottom end surface of the optical fiber.

The rotation driving device 53 may include, for example, a rotation driving motor and a rotation transmission, and a rotation driving gear 531 constantly engaged with the rotation driven gear 52 is attached to an output shaft of the rotation transmission.

When the rotation driving device 53 is turned on, the rotation driven gear 52 rotates around the center axis of the polishing center shaft 51, and the rotation driven gear 52 and the polishing center shaft 51 are relatively rotatably attached via the rotary bearing 59, so that the polishing center shaft 51 does not rotate therewith, and the revolution swing transmission wheel 54 is not driven, and the polishing disk holder 58 rotates around the polishing center shaft 51 with the rotation driven gear 52 at a fixed position on the rotation driven gear 52, thereby generating a rotation motion.

After the orbital swing drive device 55 is turned on, the grinding center shaft 51 starts to rotate, and similarly, the grinding center shaft 51 does not affect the rotation driven gear 52. The revolution swing transmission wheel 54a in transmission connection with the grinding central shaft 51 starts to rotate, the revolution swing shifting pin 56 on the revolution swing transmission wheel starts to rotate around the rotating shaft of the corresponding revolution swing transmission wheel 54a, due to the connection effect of the synchronous shifting connecting disc 57, the three revolution swing shifting pins 56 form synchronous shifting rotation with the same angle and the same rotating speed, the grinding disc seat 58 is finally driven to rotate around the rotating shaft of the revolution swing transmission wheel 54 to form revolution swing motion, and the revolution swing track of the grinding disc seat 58 is consistent with the track of the revolution swing shifting pin 56.

When the rotation driving device 53 and the revolution pendulum driving device 55 are both turned on, the grinding plate base 58 forms a composite motion of rotation and revolution pendulum, and can grind the bottom end surface of the optical fiber wire in the optical fiber connector from multiple directions, thereby forming a good grinding effect.

It will be appreciated that the abrasive disc arrangement 5 may also be used in other conventional techniques for end-face grinding, such as by using a motor-driven abrasive pad.

Fig. 1-4 also show a polishing apparatus 100 (fully automated fiber optic connector polishing apparatus) that can be used for fully automated fiber optic connector polishing.

The polishing apparatus 100 may include the polishing assembly 10 described above. The grinding apparatus 100 may further include a frame 1. The grinding base 4 of the grinding assembly 10 may be vertically movably mounted on the frame 1. The frame 1 is generally a combination of profiles and plates, well known to those skilled in the art and will not be described in detail here. Referring to fig. 2, the grinding base 4 may be vertically slidably mounted on the frame 1, for example, the grinding base 4 may be vertically slidably mounted on the frame 1 through four guide rod guide structures 42, as shown in fig. 2 and 3.

Grinding apparatus 100 may also include a grinding feed 41 for driving grinding base 4 vertically, i.e., for driving grinding assembly 10 vertically as a whole. Referring to fig. 2, a grinding and feeding device 41 may be disposed between the grinding base 4 and the frame 1, specifically, the grinding and feeding device 41 may be implemented by an electric cylinder, an air cylinder, a hydraulic cylinder, or the like, and is fixedly mounted on the frame 1, and an output shaft of the output linear motion of the grinding base drives the grinding base 4 and the grinding assembly 10 to integrally slide vertically by connecting four guide rod and guide sleeve structures 42.

The polishing apparatus 100 may further include a transfer driving apparatus 3 for driving the connector carrier 2 mounted with the plug fixing strip 22 to be transferred between different stations. Referring to fig. 1 and 4, the connector carrier 2 can be transversely (along the length direction L1) slidably mounted on the rack 1, and two connector clamps 21 (plug fixing strips 22) are symmetrically disposed on the connector carrier 2, that is, the connector carrier 2 transports two batches of optical fiber connectors at a time, it can be understood that two corresponding optical fiber connectors in the width direction W1 in the two batches of optical fiber connectors transported by the connector carrier 2 can be two end portions of the same optical fiber connector, in other words, the connector carrier 2 transports two end portions of one batch of optical fiber connectors at a time. A transmission driving device 3 may be disposed between the connector carrier 2 and the rack 1, and the transmission driving device 3 may drive the connector carrier 2 to transmit between different stations, so as to drive the optical fiber connectors on the connector clamps 21 (plug fixing strips 22) to transmit at different stations.

The position of the grinding disc device 5 is a grinding station. When the connector carrier 2 is transferred to the polishing station by the transfer drive device 3, the optical fiber connectors on the connector holder 21 (plug fixing bar 22) are positioned above the polishing disc device 5. The grinding and feeding device 41 drives the grinding base 4 to rise to the highest position, and the grinding disc device 5 is in contact with the optical fiber connector, of course, the bottom end face of the optical fiber in the optical fiber connector is in contact at the moment. The grinding jig 6 clamps and fixes the connector jig 21, and in the conventional art, clamps and fixes the plug fixing strip 22 in the connector jig 21. Then, the polishing disk device 5 is turned on to polish the bottom end surfaces of the optical fiber lines in the optical fiber connector. After polishing, the polishing disc device 5 is stopped, the polishing jig 6 is released from clamping, and the polishing base 4 is returned by the polishing feed device 41, thereby completing the automatic polishing operation.

After the grinding feeding device 41 drives the grinding base 4 to rise and the grinding disc device 5 to contact with the optical fiber connector, the two fixed strip carrying tables 61 contact with the two ends of the plug fixed strip 22, the clamping force applicator 64 drives the movable clamping block 63 to move towards the fixed clamping block 62 to clamp the plug fixed strip 22, and the two corner pressing cylinders 66 can also respectively press and hold the two ends of the plug fixed strip 22 to finally fix the plug fixed strip 22 in the connector clamp 21. The end side baffle 65 can be used as a centering limit in the width direction W1 of the plug fixing strip 22 when the grinding base 4 is fed upwards, and is matched with the clamping action of the fixed clamping block 62 and the movable clamping block 63, so that the optical fiber connector clamped and fixed cannot be obviously deviated in a horizontal plane.

As mentioned above, in practical applications, the plug fixing strip 22 can be fixed on the connector carrier 2 by the magnetic attraction device 23. The magnetic attraction can be maintained throughout the grinding process.

In another embodiment, when the polishing base 4 is driven to be raised to the highest position, the polishing disk device 5 can be kept at a slight distance from the bottom surface of the optical fiber line of the optical fiber connector and the fixed bar stages 61 can be kept at a slight distance from the both ends of the plug fixed bar 22 without directly contacting the polishing disk device 5 with the bottom surface of the optical fiber line in the optical fiber connector and directly contacting the fixed bar stages 61 with the both ends of the plug fixed bar 22.
