EMBODIMENT

[0039] Please refer to Figures 1-6A fiber optic sleeve end polishing machine includes a frame 1, two rotating shafts 2 symmetrically distributed and rotatably connected to the inner side wall of the frame 1, a conveyor belt 3 sleeved on the outer surface of the two rotating shafts 2, and multiple bearing blocks 4 equidistantly distributed on the outer surface of the conveyor belt 3; a support frame 5 fixed to one side wall of the frame 1, a positioning component 6 adapted to the bearing block 4 on one side of the support frame 5, a mounting frame 7 fixed to one side wall of the frame 1, and a polishing component 8 on one side of the mounting frame 7; and a servo motor 9 fixed to one side wall of the frame 1, with a sprocket 10 fixed between the output shaft of the servo motor 9 and one of the rotating shafts 2, and the two sprockets 10 being connected by a chain 11.

[0040] In the embodiments of this application, the positioning component 6 includes a mounting groove 61, which is formed on one side wall of the support frame 5. A cylinder 62 is fixed inside the mounting groove 61, and a connecting frame 63 is fixed to the output end of the cylinder 62. A buffer plate 64 is fixed to the bottom side wall of the connecting frame 63, and a plurality of positioning blocks 65 are fixed to the bottom side wall of the buffer plate 64. Driven by the cylinder 62, the positioning blocks 65 and the rubber pad ring 13 can move synchronously. The precise synchronous movement mechanism enables the optical fiber sleeve to be accurately pressed and positioned. During the grinding process of the end of the optical fiber sleeve, it can effectively prevent the optical fiber sleeve from deviating or shifting, thereby improving the quality and efficiency of the grinding of the end of the optical fiber sleeve.

[0041] In the embodiments of this application, the polishing assembly 8 includes two drive rollers 81, which are symmetrically distributed and rotatably connected to one side wall of the mounting frame 7. A pulley 82 is provided between each of the two drive rollers 81, and a belt 83 is sleeved on the outer surface of the two pulleys 82. A guide roller 84 is slidably connected to one side wall of the mounting frame 7, and a polishing belt 85 is sleeved on the outer surface of the guide roller 84 and the two drive rollers 81. A tensioning assembly 12 adapted to the polishing belt 85 is provided on one side of the mounting frame 7. A support plate a86 is fixed to one side wall of the mounting frame 7, and a motor a87 is fixed to the top side wall of the support plate a86. The output shaft of the motor a87 is fixed to one end of one of the drive rollers 81. Through the setting of the polishing assembly 8, the polishing belt 85 is driven by the motor a87 to rotate at a constant and uniform speed, which not only ensures the smoothness and consistency of the polishing action, but also significantly improves the polishing effect on the end of the optical fiber sleeve. The polishing belt 85 can contact the end surface of the optical fiber sleeve more evenly, thereby achieving a more refined and smooth polishing effect.

[0042] In this embodiment, the tensioning assembly 12 includes two guide grooves 121, which are symmetrically distributed and formed on one side wall of the mounting frame 7. The guide roller 84 is slidably connected to the inside of the two guide grooves 121. Two mounting blocks 122 are symmetrically distributed and fixed to one side wall of the mounting frame 7. A lead screw 123 is rotatably connected to the adjacent side wall of the two mounting blocks 122. A threaded sleeve 124 is threaded to the external thread of the lead screw 123. One end of the guide roller 84 is rotatably connected to one side wall of the threaded sleeve 124. A support plate b125 is fixed to one side wall of the mounting frame 7. A motor b126 is fixed to one side wall. One end of the output shaft of the motor b126 is coaxially fixed to one end of the lead screw 123. Through the setting of the tensioning component 12, the user can flexibly adjust the tension of the polishing belt 85 according to the actual polishing requirements. The adjustable tensioning mechanism ensures that the polishing belt 85 always maintains an appropriate tension during use, thereby effectively avoiding the problem of the polishing belt 85 becoming loose due to insufficient tension. A loose polishing belt 85 may have a negative impact on the polishing effect of the fiber optic sleeve end, resulting in uneven polishing and a decrease in polishing accuracy. This ensures that the polishing effect of the fiber optic sleeve end reaches the best state.

[0043] Furthermore, the positioning block 65 is arranged in a semi-circular arc shape on the side near the bearing block 4, and the positioning block 65 is located directly above the bearing block 4; a rubber pad ring 13 is fixed on one side wall of the positioning block 65, and the central axis of the rubber pad ring 13 is collinear with the central axis of the positioning block 65. Through the cooperation of the positioning block 65 and the rubber pad ring 13, the purpose of accurately positioning the optical fiber sleeve is achieved, thereby greatly improving the stability during the grinding of the end of the optical fiber sleeve and effectively preventing the optical fiber sleeve from deviating during grinding.

[0044] Furthermore, one side of the guide groove 121 is set with a smooth arc surface, and the grinding belt 85 is located on one side of the bearing block 4. The setting of the guide groove 121 can prevent the guide roller 84 from getting stuck when moving in the guide groove 121. A base plate 14 is fixed to the bottom side wall of the frame 1. The projected area of ​​the base plate 14 is larger than the projected area of ​​the frame 1. The setting of the base plate 14 can support the frame 1 and prevent the device from shaking due to instability during operation.

[0045] During implementation, when the end of the optical fiber sleeve needs to be ground, the servo motor 9 drives the sprocket 10 to rotate synchronously. The meshing transmission between the sprocket 10 and the chain 11 causes the rotating shaft 2 to rotate synchronously, which in turn drives the conveyor belt to transport the optical fiber sleeve to the position directly below the rubber pad ring 13. Driven by the cylinder 62, multiple rubber pad rings 13 move synchronously, pressing the optical fiber sleeve against the bearing block 4. Driven by the motor a87, the transmission roller 81 rotates synchronously. The transmission action of the pulley 82 and the belt 83 causes the two transmission rollers 81 to rotate synchronously, causing the grinding belt 85 to rotate synchronously. The grinding belt 85 grinds the end of the optical fiber sleeve. When the tension of the grinding belt 85 needs to be adjusted, the motor b126 drives the lead screw 123 to rotate synchronously. The threaded transmission between the lead screw 123 and the lead sleeve 124 drives the guide roller 84 to move synchronously, thereby adjusting the tension of the grinding belt 85.

[0046] In this application, the rubber pad ring 13 has a smooth arc surface on one side, and the polishing belt 85 has a flat surface on the side near the bearing block 4. The smooth arc surface of the rubber pad ring 13 improves the stability of the fiber optic sleeve during clamping and positioning, effectively preventing jamming during clamping and positioning, and making the clamping and positioning of the fiber optic sleeve more accurate. A reinforcing plate 15 is fixed to one side wall of the mounting frame 7. The reinforcing plate 15 has an L-shaped cross-section. The reinforcing plate 15 can greatly improve the overall stability of the mounting frame 7, thereby improving the stability of the polishing belt 85 during use and effectively preventing the polishing belt 85 from deviating.
