When in use, the rotating shaft 2 is driven to rotate by the servo motor 3, and then the grinding plate 4 and the grinding paper 5 on its upper side are driven to rotate eccentrically around the rotating shaft 2.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 8As shown, two self-rotating mechanisms 7 are arranged above the grinding platform 1, and the two self-rotating mechanisms 7 are symmetrically arranged about the axis of the rotating shaft 2. The upper end of the rotating shaft 2 is fixedly sleeved with a driving gear 6. The self-rotating mechanism 7 includes a slide bar 701 that slides through the support plate 13, and a rotating ring 702 is fixedly arranged at the lower end of the slide bar 701. A rotating rod 703 is rotatably arranged at the lower side of the rotating ring 702. The outer fixed sleeve of the rotating rod 703 is provided with a self-rotating gear 704 that meshes with the driving gear 6. The thickness of the self-rotating gear 704 is at least three times that of the driving gear 6. A clamping mechanism 8 is arranged at the lower end of the rotating rod 703, and an MPO optical fiber connector (not shown in the figure) can be fixedly clamped by the clamping mechanism 8. During the grinding process, the rotating shaft 2 is driven to rotate by the servo motor 3, and then the driving gear 6 on the rotating shaft 2 is driven to rotate, so that the two self-rotating gears 704 that mesh with the driving gear 6 can be rotated, and then the rotating rod 703 is driven to rotate at the lower side of the rotating ring 702. By rotating the clamping mechanism 8 at the lower end of the rotating rod 703, the multiple MPO fiber optic connectors fixed on the lower side of the clamping mechanism 8 can be rotated, and then the multiple MPO fiber optic connectors can be rotated to grind the upper surface of the grinding paper 5 on the upper side of the grinding plate 4. At the same time, the grinding plate 4 and the grinding paper 5 can also be used to grind relative to the multiple MPO fiber optic connectors, thereby further improving the grinding efficiency. A hanging bracket 9 is fixedly provided on the upper side of the support plate 13, and a plurality of electric telescopic rods 15 are fixedly provided on the lower side of the hanging bracket 9 for driving the sliding rod 701 to move up and down respectively. The sliding rod 701 is driven to move up and down by the electric telescopic rod 15, and then the self-rotating gear 704 on the sliding rod 701 is driven to slide and mesh on the driving gear 6, thereby driving the clamping mechanism 8 at the lower end of the sliding rod 701 to move up and down, so that the multiple MPO fiber optic connectors on the lower side of the clamping mechanism 8 can be lifted and lowered, so that the grinding height of the MPO fiber optic connector can be adjusted, thereby improving the grinding efficiency.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7As shown, the clamping mechanism 8 includes a top plate 801 fixedly arranged at the lower end of the rotating rod 703, a screw hole 808 is opened at the lower end of the rotating rod 703, a screw 807 matched with the screw hole 808 is arranged in the middle of the top plate 801, and the screw 807 passes through the middle of the top plate 801 and matches with the screw hole 808, so that the clamping mechanism 8 can be replaced easily, and multiple clamping mechanisms 8 can be replaced easily to improve the grinding efficiency. A plurality of first fixing plates 802 are equidistantly arranged on the circumference of the lower side of the top plate 801, and a plurality of second fixing plates 803 corresponding to the first fixing plates 802 are equidistantly arranged on the edge circumference of the top plate 801, a screw rod 804 is arranged through the middle thread of the second fixing plate 803, and a clamping plate 806 matched with the first fixing plate 802 is arranged at one end of the screw rod 804, A knob 805 is fixedly provided at the other end of the screw rod 804. When in use, the MPO fiber optic connector is placed between the first fixed plate 802 and the clamping plate 806, and then the knob 805 is turned to drive the screw rod 804 to move on the second fixed plate 803, thereby driving the clamping plate 806 at one end of the screw rod 804 to press the MPO fiber optic connector against one side of the first fixed plate 802, so that the MPO fiber optic connector can be fixed between the clamping plate 806 and the first fixed plate 802. Four waste chip openings 11 are opened on the grinding platform 1, two of which are located below the clamping mechanism 8. The waste glass chips ground from the port of the MPO fiber optic connector can fall through the waste chip openings 11 to prevent the waste glass chips from accumulating on the grinding platform 1 and affecting subsequent grinding.

[0023] Embodiment 2: Based on embodiment 1, further improvement is made in that Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a brush mechanism 10 that cooperates with the end faces of multiple MPO fiber optic connectors is fixedly arranged on one side of the short axis of the grinding plate 4. The brush mechanism 10 includes a mounting plate 1001 fixedly arranged on one side of the short axis of the grinding plate 4, and a first brush 1002 is fixedly arranged on the upper side of the mounting plate 1001. When in use, the grinding plate 4 will also drive the mounting plate 1001 on the side of the short axis of the grinding plate 4 to rotate during rotation, thereby driving the first brush 1002 on the upper side of the mounting plate 1001 to rotate together. When the long axis side of the grinding plate 4 passes through multiple MPO fiber optic connectors, the end faces of multiple MPO fiber optic connectors will be ground. When the short axis side of the grinding plate 4 passes through the MPO fiber optic connector, the first brush 1002 will scrape off the glass waste on the end face of the MPO fiber optic connector, so that the glass waste will fall out through the waste opening 11, thereby preventing the glass waste from scratching the end face of the MPO fiber optic connector during the next grinding process.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, both sides of the support plate 13 are provided with a chip suction mechanism 14 that cooperates with the grinding paper 5, wherein two waste chip ports 11 are located below the chip suction mechanism 14, and the chip suction mechanism 14 includes a hanging plate 1401 fixedly arranged on one side of the support plate 13, a hanging rod 1402 is fixedly arranged on the lower side of the hanging plate 1401, a horizontal plate 1403 is fixedly arranged on the lower end of the hanging rod 1402, and a second brush 1406 located on both sides of a chip suction cover 1404 is fixedly arranged on the lower side of the horizontal plate 1403, and the glass waste on the upper side of the grinding paper 5 can be brushed into the waste chip port 11 through the second brush 1406, a chip suction cover 1404 that cooperates with the grinding paper 5 is arranged on the lower side of the horizontal plate 1403, and a chip suction pipe 1405 connected to the chip suction cover 1404 is arranged on the upper side of the horizontal plate 1403. One end of 1405 is connected to a vacuum cleaner (not shown in the figure). When in use, when the long axis of the grinding plate 4 moves to the lower side of the chip suction cover 1404, the glass waste on the surface of the grinding paper 5 on the upper side of the grinding plate 4 will be sucked by the vacuum cleaner, so that the glass waste on the surface of the grinding paper 5 can be cleaned. On the one hand, it can improve the effect of the next grinding, and on the other hand, it can prevent the glass waste from scratching the end face of the MPO optical fiber connector. In addition, the second bristles 1406 on both sides of the chip suction cover 1404 can brush off the glass waste on the surface of the grinding paper 5, further improving the cleaning effect. At the same time, when the chip brushing mechanism 10 passes through the second bristles 1406, the second bristles 1406 and the first bristles 1002 brush off the residual waste on each other, and the waste falls into the waste opening 11 for collection.

[0025] It should be noted that, when using the MPO fiber optic connector processing device, the MPO fiber optic connector is placed between the first fixing plate 802 and the clamping plate 806, and then the knob 805 is turned to drive the screw rod 804 to move on the second fixing plate 803, thereby driving the clamping plate 806 at one end of the screw rod 804 to press the MPO fiber optic connector on one side of the first fixing plate 802, so that the MPO fiber optic connector can be fixed between the clamping plate 806 and the first fixing plate 802, and then the servo motor 3 drives the rotating shaft 2 to rotate, thereby driving the grinding plate 4 and the grinding paper 5 on its upper side to rotate eccentrically around the rotating shaft 2, and at the same time, the rotating shaft 2 drives the driving gear 6 to rotate, so that the two self-rotating gears meshing with the driving gear 6 can rotate. 704 rotates, thereby driving the rotating rod 703 to rotate on the lower side of the rotating ring 702, so that the clamping mechanism 8 at the lower end of the rotating rod 703 rotates, and the multiple MPO fiber optic connectors fixed on the lower side of the clamping mechanism 8 can be rotated, and then the multiple MPO fiber optic connectors can be rotated to grind the upper surface of the grinding paper 5 on the upper side of the grinding plate 4, so that the multiple MPO fiber optic connectors can be ground under the action of their own rotation and the revolution of the grinding paper 5. In the process of grinding, the rotating shaft 2 will drive the eccentric rotation of the grinding plate 4, and will also drive the mounting plate 1001 on the short axis side of the grinding plate 4 to rotate, thereby driving the first brush 1002 on the upper side of the mounting plate 1001 to rotate together. When one side of the short axis of the grinding plate 4 passes through the MPO fiber optic connector, it will pass The first brush 1002 scrapes away the glass waste on the end face of the MPO optical fiber connector, so that the glass waste falls out through the waste opening 11. When the long axis of the grinding plate 4 moves to the lower side of the chip suction cover 1404, the glass waste on the surface of the grinding paper 5 on the upper side of the grinding plate 4 is sucked by the vacuum cleaner, so that the glass waste on the surface of the grinding paper 5 can be cleaned, and the second brushes 1406 on both sides of the chip suction cover 1404 can brush away the glass waste on the surface of the grinding paper 5, further improving the cleaning effect. After the multiple MPO optical fiber connectors on the lower side of the clamping mechanism 8 on one side are ground once by the grinding paper 5 (that is, when the grinding paper 5 passes through the clamping mechanism 8), the servo motor 3 continues to drive the rotating shaft 2 to rotate, so that the grinding plate 4 is located at the clamping mechanism on the other side. The servo motor 3 stops rotating, and then the electric telescopic rod 15 on the upper side of the grinding plate 4 drives the self-rotating mechanism 7 and the clamping mechanism 8 to descend, so that the MPO optical fiber connector on the lower side of the clamping mechanism 8 is pressed tightly against the upper side of the grinding paper 5. At the same time, the electric telescopic rod 15 on the other side also drives the self-rotating mechanism 7 and the clamping mechanism 8 to descend. The servo motor 3 then continues to drive the rotating shaft 2 to rotate, so that the end face of the MPO optical fiber connector after the first grinding can be brushed by the first brush 1002, and the MPO optical fiber connector on one side is ground at the same time. When the grinding and brushing are completed, the servo motor 3 stops rotating, and the electric telescopic rod 15 on one side drives the self-rotating mechanism 7 and the clamping mechanism 8 to rise, and the clamping mechanism 8 on the other side descends.The servo motor 3 continues to drive the shaft 2 to rotate, and the end face of the MPO fiber optic connector after the first grinding can be brushed by the first brush 1002. At this time, the end faces of the MPO fiber optic connectors on both sides have completed one grinding and one brushing. The servo motor 3 stops driving the shaft 2 to rotate, and then the electric telescopic rod 15 drives the self-rotating mechanism 7 and the clamping mechanism 8 to rise. Repeat the above operation, and the MPO fiber optic connector can be continuously ground and the glass waste can be brushed.

[0026] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention.
