Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically to a polishing device for producing optical fiber communication guide pins. Background Technology

[0002] When splicing optical fibers, the connectors are small, and deviations can easily damage them or cause connection errors. Therefore, guide pins are needed to facilitate connector insertion. In the production of guide pins for optical fiber communication, grinding is a key process. Its purpose is to remove burrs and sharp edges from both ends of the guide pin and ensure the flatness and perpendicularity of the end face to meet the accuracy requirements of subsequent assembly. However, traditional feeding methods often rely on manual handling or simple vibratory feeders. Due to the small size and smooth surface of the guide pins, uneven feeding spacing, stacking, or jamming can easily occur, making it difficult to achieve precise feeding of a single fiber and affecting the consistency of subsequent grinding and positioning. Grinding often uses a fixed clamp to hold the guide pin and a single grinding head to reciprocate. This requires frequent clamp adjustments to adapt to guide pins of different lengths, and grinding at both ends needs to be completed in two separate processes. This is not only inefficient but also results in inconsistent grinding amounts at both ends due to positioning errors in the two clamping processes, making it difficult to guarantee the product qualification rate. Therefore, a highly automated guide pin production equipment that can accurately position and efficiently complete grinding is needed. Summary of the Invention

[0003] This invention aims to solve the above-mentioned technical problems by providing a grinding device for the production of optical fiber communication guide pins.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: a grinding device for producing optical fiber communication guide pins, including a processing table, a feeding mechanism on one side of the top of the processing table, and a grinding mechanism connected to one side of the feeding mechanism; the feeding mechanism includes two parallel No. 1 support plates, and a feeding roller is rotatably connected between the tops of the two No. 1 support plates, the feeding roller being driven by a No. 1 servo motor fixed on the No. 1 support plate; a guide groove is fixedly connected between the two No. 1 support plates and on the side near the grinding mechanism; the grinding mechanism includes a grinding table, the grinding table being fixedly connected to the end of the guide groove away from the feeding mechanism, and sliders that can slide along the length of the grinding table and move closer to each other at both ends of the grinding table, trapezoidal grinding sleeves being rotatably connected to the tops of the two sides of the sliders that move closer to each other, the trapezoidal grinding sleeves being driven by a No. 3 servo motor fixed on the sliders.

[0005] As a preferred technical solution of this utility model, a material box is fixedly connected between the tops of the two No. 1 support plates, and a plurality of feeding grooves are equidistantly opened on the outer wall of the feeding roller along the circumference. The bottom opening of the material box is connected to the upper opening of the feeding groove. The output end of the No. 1 servo motor passes through the No. 1 support plate and is fixedly connected to the rotation shaft of the feeding roller.

[0006] As a preferred technical solution of this utility model, two parallel No. 2 support plates are fixedly connected to the bottom ends of the grinding table, and a bidirectional lead screw is rotatably connected between the two No. 2 support plates. The two ends of the bidirectional lead screw are respectively threaded to the bottom of the two sliders.

[0007] As a preferred technical solution of this utility model, a second servo motor is fixedly connected to one of the second support plates, and the output end of the second servo motor passes through the second support plate and is fixedly connected to one end of the bidirectional lead screw.

[0008] As a preferred technical solution of this utility model, a limiting block is fixedly connected to the top of the side of the grinding table away from the guide groove.

[0009] As a preferred technical solution of this utility model, a third servo motor is fixedly connected to the side of each of the two sliders away from the other slider. The output end of the third servo motor passes through the slider and is fixedly connected to the rotating shaft of the trapezoidal grinding sleeve. The third servo motor, the first servo motor and the second servo motor are all controlled by an encoder.

[0010] This utility model has the following advantages: the coordinated design of the material box and the feeding roller, combined with the No. 1 servo motor driving the feeding roller to rotate, realizes the single quantitative feeding of the guide needle; the guide groove further guides the guide needle to roll smoothly to the grinding table, avoiding stacking or deviation, and solves the problems of uneven spacing and jamming in the traditional feeding method. The grinding mechanism adjusts the slider spacing via a bidirectional lead screw to accommodate guide pins of different lengths. Two trapezoidal grinding sleeves are driven by independent No. 3 servo motors to rotate in opposite directions, simultaneously applying uniform pressure to both ends of the guide pins for grinding. This avoids the problem of uneven end faces caused by the cancellation of grinding forces when rotating in the same direction, while also reducing the number of clamping operations and improving production efficiency and product qualification rate.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please refer to the following: Figure 1-4 This utility model discloses a grinding device for producing fiber optic communication guide pins, comprising a processing table 1, a feeding mechanism 2 on one side of the top of the processing table 1, and a grinding mechanism 3 connected to one side of the feeding mechanism 2; the feeding mechanism 2 includes two parallel first support plates 4, and a feeding roller 5 is rotatably connected between the tops of the two first support plates 4, the feeding roller 5 being driven by a first servo motor 7 fixed on the first support plate 4; a guide groove 9 is fixedly connected between the two first support plates 4 and on the side closer to the grinding mechanism 3; the grinding mechanism 3 includes a grinding table 10, the grinding table 10 being fixedly connected to the end of the guide groove 9 away from the feeding mechanism 2, and two sliders 13 at both ends of the grinding table 10 being slidable along the length of the grinding table and able to approach each other, trapezoidal grinding sleeves 14 being rotatably connected to the tops of the two sides of the two sliders 13 approaching each other, the trapezoidal grinding sleeves 14 being driven by a third servo motor 16 fixed on the sliders 13.

[0017] A material box 8 is fixedly connected between the tops of the two No. 1 support plates 4. Several feeding grooves 6 are equidistantly opened on the outer wall of the feeding roller 5 along the circumference. The bottom opening of the material box 8 is connected to the upper opening of the feeding groove 6. The output end of the No. 1 servo motor 7 passes through the No. 1 support plate 4 and is fixedly connected to the rotating shaft of the feeding roller 5.

[0018] Two parallel support plates 11 are fixedly connected to the bottom ends of the grinding table 10. A bidirectional lead screw 12 is rotatably connected between the two support plates 11. The two ends of the bidirectional lead screw 12 are respectively threaded to the bottom of the two sliders 13.

[0019] A second servo motor 15 is fixedly connected to one of the second support plates 11. The output end of the second servo motor 15 passes through the second support plate 11 and is fixedly connected to one end of the bidirectional lead screw 12.

[0020] A limiting block 17 is fixedly connected to the top of the side of the grinding table 10 away from the guide chute 9.

[0021] Two sliders 13 are fixedly connected to a third servo motor 16 on the side away from the other slider. The output end of the third servo motor 16 passes through the slider 13 and is fixedly connected to the rotating shaft of the trapezoidal grinding sleeve 14. The third servo motor 16, the first servo motor 7 and the second servo motor 15 are all controlled by an encoder.

[0022] Specifically, when using this utility model, the guide pins to be polished are loaded into the material box 8 in batches. The bottom opening of the material box 8 corresponds one-to-one with the feeding groove 6 of the feeding roller 5. At this time, the feeding roller 5 is stationary, and the bottommost guide pin falls into the feeding groove 6.

[0023] Start the No. 1 servo motor 7 to drive the feeding roller 5 to rotate at a constant speed. The feeding groove 6 carries the guide pin and moves along the roller axis. When the feeding groove 6 rotates to the end, the guide pin leaves the groove due to gravity and rolls along the guide groove 9 toward the grinding table 10. The inclination angle of the guide groove 9 is 15° to ensure that the guide pin slides smoothly and avoids jumping or jamming.

[0024] When the guide pin slides to the grinding table 10, its front end first contacts the limiting block 17, which not only prevents the guide pin from continuing to slide and avoids it from rushing out due to inertia, but also allows the guide pin to remain in a horizontal state, providing stable positioning for subsequent grinding.

[0025] Based on the current length of the guide pin, start the second servo motor 15 to drive the bidirectional lead screw 12 to rotate. The threads at both ends of the bidirectional lead screw 12 rotate in opposite directions, causing the two sliders 13 to move towards each other along the second support plate 11. The top of the sliders 13 is slidably connected to the grinding table 10 through the guide rail to ensure the movement accuracy. When the center of the inner hole of the two trapezoidal grinding sleeves 14 is aligned with the two ends of the guide pin, the second servo motor 15 stops running.

[0026] Two servo motors 16 are started, driving the left trapezoidal grinding sleeve 14 to rotate clockwise and the right trapezoidal grinding sleeve 14 to rotate counterclockwise, respectively. At the same time, servo motor 15 is started again, driving the slider 13 to continue moving towards each other until the grinding sleeve contacts both ends of the guide pin. Since the inner hole of the grinding sleeve matches the outer contour of the guide pin and has a slight taper, it automatically centers and applies constant pressure upon contact. The counterclockwise rotating grinding sleeve cancels out the radial runout during unidirectional rotation, ensuring that the grinding amount at both ends is uniform.

[0027] After grinding is completed, servo motor 16 stops rotating, servo motor 15 reverses to drive slider 13 to reset, guide pin loses support from grinding sleeve, removes guide pin, repeats the above steps to achieve continuous automated production.

[0028] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
