Detailed implementation manners

[0028] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0029] Example 1: As shown in Figure 1 , Figure 2As shown in the figure, an MPO fiber optic connector processing device includes a grinding platform 1. Support legs are arranged around the lower side of the grinding platform 1. On both sides of the grinding platform 1, support rods 12 are fixedly arranged respectively. At the upper ends of the support rods 12, a support plate 13 is fixedly arranged. In the middle of the upper side of the grinding platform 1, a rotating shaft 2 is rotatably arranged. The upper end of the rotating shaft 2 is rotatably connected to the support plate 13. The support plate 13 can limit the upper end of the rotating shaft 2 to ensure that the rotating shaft 2 is more stable during rotation. At the bottom of the grinding platform 1, a servo motor 3 for driving the rotation of the rotating shaft 2 is fixedly arranged. On the rotating shaft 2, a grinding plate 4 rotatable on the upper side of the grinding platform 1 is fixedly arranged. The grinding plate 4 is eccentrically fixed on the rotating shaft 2. That is, when the rotating shaft 2 rotates, it drives the grinding plate 4 to rotate eccentrically around the rotating shaft 2. A grinding paper 5 is arranged on the upper side of the grinding plate 4. During use, the servo motor 3 drives the rotating shaft 2 to rotate, and then drives the grinding plate 4 and the grinding paper 5 on its upper side to rotate eccentrically around the rotating shaft 2.

[0030] As Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 8As shown, there are two self-rotation mechanisms 7 arranged above the grinding platform 1. The two self-rotation mechanisms 7 are symmetrically arranged with respect to 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-rotation mechanism 7 includes a slide bar 701 that slidably penetrates through the support plate 13. The lower end of the slide bar 701 is fixedly provided with a rotating ring 702. The lower side of the rotating ring 702 is rotatably provided with a rotating rod 703. The outer side of the rotating rod 703 is fixedly sleeved with a self-rotation gear 704 that meshes with the driving gear 6. The thickness of the self-rotation gear 704 is at least three times that of the driving gear 6. The lower end of the rotating rod 703 is provided with a clamping mechanism 8. Through the clamping mechanism 8, the MPO fiber optic connector (not shown in the figure) can be fixedly clamped. During the grinding process, the servo motor 3 drives the rotating shaft 2 to rotate, and then drives the driving gear 6 on the rotating shaft 2 to rotate, which can make the two self-rotation gears 704 meshing with the driving gear 6 rotate. Then it drives the rotating rod 703 to rotate under the lower side of the rotating ring 702, making the clamping mechanism 8 at the lower end of the rotating rod 703 rotate, so that the multiple MPO fiber optic connectors fixed under the clamping mechanism 8 rotate. Thus, the multiple MPO fiber optic connectors rotate and are ground on the upper surface of the abrasive paper 5 on the upper side of the grinding plate 4. At the same time, the grinding plate 4 and the abrasive paper 5 can also revolve relative to the multiple MPO fiber optic connectors for grinding, further improving the grinding efficiency. The upper side of the support plate 13 is fixedly provided with a suspension bracket 9. The lower side of the suspension bracket 9 is fixedly provided with a number of electric telescopic rods 15 that respectively drive the slide bar 701 to move up and down. The electric telescopic rods 15 drive the slide bar 701 to move up and down, and then drive the self-rotation gear 704 on the slide bar 701 to slide and mesh on the driving gear 6, and then drive the clamping mechanism 8 at the lower end of the slide bar 701 to move up and down, so that the multiple MPO fiber optic connectors under the clamping mechanism 8 move up and down, adjusting the grinding height of the MPO fiber optic connector and improving the grinding efficiency.

[0031] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7As shown in the figure, 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 provided 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. By passing the screw 807 through the middle of the top plate 801 and matching it with the screw hole 808, it is convenient to replace the clamping mechanism 8 and convenient to replace multiple clamping mechanisms 8, improving the grinding efficiency. A number of first fixing plates 802 are equidistantly arranged on the lower side circumference of the top plate 801. A number 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 lead screw 804 is threadedly penetrated through the middle of the second fixing plate 803. A clamping plate 806 clamped and matched with the first fixing plate 802 is arranged at one end of the lead screw 804. A knob 805 is fixedly arranged at the other end of the lead screw 804. When in use, put the MPO fiber optic connector between the first fixing plate 802 and the clamping plate 806, and then rotate the knob 805, which can drive the lead screw 804 to move on the second fixing plate 803, and further drive the clamping plate 806 at one end of the lead screw 804 to press the MPO fiber optic connector against one side of the first fixing plate 802, so that the MPO fiber optic connector is fixed between the clamping plate 806 and the first fixing plate 802. Four waste chip openings 11 are provided on the grinding platform 1, and two of the waste chip openings 11 are located below the clamping mechanism 8. Through the waste chip openings 11, the glass waste chips ground from the port of the MPO fiber optic connector can fall, preventing the glass waste chips from accumulating on the grinding platform 1 and affecting subsequent grinding.

[0032] Embodiment 2: Further improvement based on Embodiment 1 lies in that, as Figure 1 , Figure 2 , Figure 3 , Figure 5 shown, a chip brushing mechanism 10 matched 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 chip brushing mechanism 10 includes a mounting plate 1001 fixedly arranged on one side of the short axis of the grinding plate 4. A first brush hair 1002 is fixedly arranged on the upper side of the mounting plate 1001. When in use, during the rotation of the grinding plate 4, it will also drive the mounting plate 1001 on one side of the short axis of the grinding plate 4 to rotate, and further drive the first brush hair 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 the 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 glass waste chips on the end face of the MPO fiber optic connector will be scraped off by the first brush hair 1002, so that the glass waste chips fall out through the waste chip opening 11, preventing the glass waste chips from scratching the end face of the MPO fiber optic connector during the next grinding.

[0033] As Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, chip suction mechanisms 14 that cooperate with the abrasive paper 5 are provided on both sides of the support plate 13. Among them, two waste chip ports 11 are located below the chip suction mechanisms 14. The chip suction mechanism 14 includes a suspension plate 1401 fixedly arranged on one side of the support plate 13. A suspension rod 1402 is fixedly arranged on the lower side of the suspension plate 1401. A cross plate 1403 is fixedly arranged at the lower end of the suspension rod 1402. Second brush hairs 1406 located on both sides of the chip suction cover 1404 are fixedly arranged on the lower side of the cross plate 1403. Through the second brush hairs 1406, the glass waste chips on the upper side of the abrasive paper 5 can be brushed into the waste chip port 11. A chip suction cover 1404 that cooperates with the abrasive paper 5 is arranged on the lower side of the cross plate 1403. A chip suction pipe 1405 that communicates with the chip suction cover 1404 is arranged on the upper side of the cross plate 1403. One end of the chip suction pipe 1405 communicates with a vacuum cleaner (not shown in the figure). During use, when the long axis of the grinding plate 4 moves to the lower side of the chip suction cover 1404, the glass waste chips on the surface of the abrasive paper 5 on the upper side of the grinding plate 4 will be attracted by the vacuum cleaner, so that the glass waste chips on the surface of the abrasive paper 5 can be cleaned. On the one hand, the effect of the next grinding can be improved. On the other hand, it can also prevent the glass waste chips from scratching the end face of the MPO fiber optic connector. And the glass waste chips on the surface of the abrasive paper 5 can be brushed off by the second brush hairs 1406 on both sides of the chip suction cover 1404, further improving the cleaning effect. At the same time, when the chip brushing mechanism 10 passes through the second brush hairs 1406, the second brush hairs 1406 and the first brush hairs 1002 brush off the residual waste chips on each other, and the waste chips fall into the waste chip port 11 for collection.

[0034] It should be noted that for this MPO fiber optic connector processing device, when in use, place the MPO fiber optic connector between the first fixed plate 802 and the clamping plate 806, and then rotate the knob 805, which can drive the lead screw 804 to move on the second fixed plate 803. Further, the clamping plate 806 at one end of the lead screw 804 presses 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. Then, drive the rotating shaft 2 to rotate through the servo motor 3, and further drive the grinding plate 4 and the abrasive paper 5 on its upper side to rotate eccentrically around the rotating shaft 2. At the same time, the rotating shaft 2 drives the driving gear 6 to rotate, which can make the two self-rotating gears 704 meshing with the driving gear 6 rotate. Further, drive the rotating rod 703 to rotate under 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 it can make the multiple MPO fiber optic connectors fixed under the lower side of the clamping mechanism 8 rotate. Further, the multiple MPO fiber optic connectors can rotate and be ground on the upper surface of the abrasive 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 abrasive paper 5. During the grinding process, when the rotating shaft 2 drives the grinding plate 4 to rotate eccentrically, it will also drive the mounting plate 1001 on the short-axis side of the grinding plate 4 to rotate, and further drive the first brush bristles 1002 on the upper side of the mounting plate 1001 to rotate together. When the short-axis side of the grinding plate 4 passes through the MPO fiber optic connector, the glass waste chips on the end face of the MPO fiber optic connector can be scraped off by the first brush bristles 1002, so that the glass waste chips fall out through the waste chip port 11. When the long axis of the grinding plate 4 moves to the lower side of the chip suction cover 1404, the glass waste chips on the surface of the abrasive paper 5 on the upper side of the grinding plate 4 can be attracted by the vacuum cleaner, so that the glass waste chips on the surface of the abrasive paper 5 can be cleaned. And the glass waste chips on the surface of the abrasive paper 5 can be brushed off by the second brush bristles 1406 on both sides of the chip suction cover 1404, further improving the cleaning effect. And when the multiple MPO fiber optic connectors under the lower side of one clamping mechanism 8 are ground once by the abrasive paper 5 (that is, when the abrasive 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 under the other clamping mechanism 8, and the servo motor 3 stops rotating. Then, drive the self-rotating mechanism 7 and the clamping mechanism 8 to descend through the electric telescopic rod 15 on the upper side of the grinding plate 4, so that the MPO fiber optic connectors under the lower side of the clamping mechanism 8 are pressed and adhered to the upper side of the abrasive 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 fiber optic connector after the first grinding can be brushed off by the first brush bristles 1002, and at the same time, the MPO fiber optic connectors on one side can be ground. When the grinding and brushing are completed, the servo motor 3 stops rotating. After the grinding and brushing are completed on one side, the electric telescopic rod 15 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 rotating 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 bristles 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 rotating shaft 2 to rotate. Then, the electric telescopic rod 15 drives the self-rotating mechanism 7 and the clamping mechanism 8 to rise. By repeating the above operations, the MPO fiber optic connector can be continuously ground and the glass chips can be brushed off.

[0035] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
