[0002] Fiber optic patch cords are used as jumpers from equipment to fiber optic cabling links. They have a thicker protective layer and are generally used to connect optical terminals and terminal boxes. They are used in fiber optic communication systems, fiber optic access networks, fiber optic data transmission, and local area networks. In order to improve the use of fiber optic patch cords, their end faces need to be polished in multiple levels. Fiber optic patch cord end face polishing equipment is a professional equipment used to perform high-precision grinding and polishing on the end faces of fiber optic patch cords.

[0040] Embodiment 2 proposed based on Embodiment 1:

[0041] Refer to Figures 2-7 On the machine base 1, a dust suction mechanism is provided, and the dust suction mechanism is used to absorb the debris and dust generated during the grinding process. The dust suction mechanism includes an arc-shaped cover 24 on one side of the machine base 1. An air inlet cover 25 is arranged inside the arc-shaped cover 24. A pipeline 26 is arranged inside the arc-shaped cover 24. The pipeline 26 is communicated with the arc-shaped cover 24 and the air inlet cover 25 through a connecting pipe 27. The connecting pipe 27 is fixedly connected with the arc-shaped cover 24, the air inlet cover 25 and the pipeline 26. The end of the pipeline 26 is communicated and fixedly installed with a vertical pipe 28. The lower end of the vertical pipe 28 is provided with an opening. A sealing plug 29 is arranged at the lower port of the vertical pipe 28. The sealing plug 29 is in transitional fit with the vertical pipe 28. A suction pump 30 is fixedly installed on the machine base 1. The intake pipe of the suction pump 30 is communicated with the upper end of the vertical pipe 28. The exhaust pipe of the suction pump 30 extends outside the machine base 1. An annular strip 31 is fixedly installed inside the vertical pipe 28. A filter plate 32 is arranged inside the vertical pipe 28. The filter plate 32 is placed on the annular strip 31. A shock-absorbing pad is arranged at the bottom of the machine base 1.

[0042] During the grinding work, by setting the suction pump 30 to suck the air in the vertical pipe 28, and cooperating with the conduction of the pipeline 26 and multiple connecting pipes 27, a negative pressure air flow is generated at the air inlet cover 25 and the arc-shaped cover 24, so that the dust and debris generated at the end face of the optical fiber are sucked in from the air inlet cover 25. The arc-shaped cover 24 absorbs the dust adhered to the grinding disc 2, so as to comprehensively absorb the dust and debris generated by grinding. The air flow containing dust and debris enters the vertical pipe 28, and the dust and debris are filtered through the filter plate 32. After the suction pump 30 stops running, the dust and debris on the filter plate 32 will fall onto the sealing plug 29 under the action of gravity. By removing the sealing plug 29 at the bottom of the vertical pipe 28, the dust and debris in the vertical pipe 28 can be cleaned.

[0043] The suction pump 30 cooperates with the pipeline network to form a negative pressure in the grinding area, and synchronously absorbs the end face debris and the residual dust on the disk surface through the air intake hood 25 and the arc-shaped hood 24, reducing secondary pollution. The filter plate 32 intercepts dust particles and automatically settles to the sealing plug 29 after the machine stops, supporting quick cleaning and reducing the maintenance cost.

[0044] Overall working principle: The working schematic diagram of the device can be referred to Figure 2 as shown. Insert the limit rod 16 through the lower limit hole 15, and insert the end of the limit rod 16 into the movable seat 10, thereby fixing the movable seat 10. Place the optical fiber in multiple clamping plates 5, and drive the multiple clamping plates 5 to clamp the optical fiber through the elastic force of the elastic member 7. Drive the connecting piece 14 to move towards the optical fiber through the electric telescopic rod 13, so that the grinding disk 2 contacts the end of the optical fiber, so that the rough grinding area 3 contacts the end of the optical fiber and can carry out grinding work. During the grinding work, drive the first pulley 18 on one side to rotate through the servo motor 17, cooperate with the belt 22 to drive the first pulley 18 on the upper side to rotate, and carry out the tensioning work on the belt 22 through the second pulleys 21 on both sides, thereby driving the internal spline tube 11 to rotate, and transmit to the grinding disk 2 through the external spline shaft 12, thereby driving the rough grinding area 3 on the grinding disk 2 to contact the optical fiber and carry out grinding work.

[0045] When it is necessary to adjust the contact between the fine grinding area 4 and the end face of the optical fiber, move the grinding disk 2 upward by a certain distance, insert the limit rod 16 into the upper limit hole 15 and insert the end into the movable seat 10, thereby fixing the movable seat 10 located above. Drive the two mounting seats 20 to move closer to each other by rotating the bidirectional lead screw 23, and the distance between the two second pulleys 21 can be adjusted to make the belt 22 in a tensioned state, so that the two first pulleys 18 are in a transmission state.

[0046] During the grinding work, by setting the suction pump 30 to suck the air in the vertical pipe 28, and cooperating with the conduction of the pipeline 26 and multiple connecting pipes 27, a negative pressure air flow is generated at the air intake hood 25 and the arc-shaped hood 24, so that the dust and debris generated at the end face of the optical fiber are sucked in from the air intake hood 25. The arc-shaped hood 24 absorbs the dust adhering to the grinding disk 2, thereby comprehensively absorbing the dust and debris generated by grinding. The air flow containing dust and debris enters the vertical pipe 28, and the dust and debris are filtered through the filter plate 32. After the suction pump 30 stops, the dust and debris on the filter plate 32 will fall onto the sealing plug 29 under the action of gravity. By disassembling the sealing plug 29 at the bottom of the vertical pipe 28, the dust and debris in the vertical pipe 28 can be cleaned.

[0047] A method for grinding the end face of an optical fiber jumper includes the following steps:

[0048] Fixing the optical fiber: Place the optical fiber between multiple elastic clamping plates 5, and use the elastic force of the elastic member 7 to automatically clamp the optical fiber by the clamping plates 5;

[0049] Coarse grinding mode setting: Insert the limit rod 16 into the lower limit hole 15 and fix the movable seat 10. Drive the connecting piece 14 through the electric telescopic rod 13 to drive the grinding disc 2 to move, so that the coarse grinding area 3 contacts the end of the optical fiber;

[0050] Power transmission: Start the servo motor 17 to drive the first pulley 18 on one side to rotate. Link the first pulley 18 on the other side through the belt 22. Tighten the belt 22 by using the second pulleys 21 on both sides, and drive the internal spline tube 11 and the external spline shaft 12 to drive the grinding disc 2, so as to realize the grinding of the optical fiber in the coarse grinding area 3;

[0051] Fine grinding mode switching: Lift the grinding disc 2 and re-insert the limit rod 16 into the upper limit hole 15 to fix the movable seat 10. Adjust the bidirectional lead screw 23 to make the mounting seat 20 drive the second pulley 21 to adjust the spacing. After tightening the belt 22, start the transmission system to make the fine grinding area 4 contact the optical fiber.
