Description

Technical Field

[0001] This utility model relates to the technical field of optical fiber processing and polishing equipment, specifically to an end face polishing device for optical fiber processing. Background Technology

[0002] Optical fiber, short for optical waveguide fiber, is a type of fiber made of glass or plastic used as a means of light transmission. The transmission principle is total internal reflection of light. The tiny optical fibers are encased in a plastic sheath, allowing them to bend without breaking. Typically, a light-emitting diode (LED) or a laser beam is used at one end of the fiber to transmit light pulses, while a photosensitive element is used at the other end to detect these pulses. In everyday life, because the transmission loss of light through optical fibers is much lower than that of electricity through wires, optical fibers are used for long-distance information transmission.

[0003] To meet diverse industrial needs, optical fibers require grinding and polishing, followed by ultrasonic cleaning before further processing. Polishing improves the smoothness of the fiber end face, contributing to higher production quality. However, the fiber processing generates significant amounts of dust that easily floats in the air. Furthermore, some polishing processes utilize grinding fluid, which can cause dust debris and grinding fluid to float or be ejected during operations, polluting the work area and making recycling and cleaning difficult. Therefore, an end-face grinding device for optical fiber processing is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an end-face grinding device for optical fiber processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an end-face grinding device for optical fiber processing, comprising a housing, a gantry fixedly mounted on the top of the housing, a sliding sleeve sleeve slidably fitted on the outer side of the top of the gantry, a high-precision electrically controlled telescopic rod fixedly mounted on the bottom of the sliding sleeve sleeve, an optical fiber clamp fixedly mounted on the output end of the high-precision electrically controlled telescopic rod, a hollow sandwich limiting cylinder fixedly mounted on the top of the housing, a conical eave fixedly mounted on the top of the hollow sandwich limiting cylinder, a plurality of flow guiding holes opened inside the conical eave, a flow guiding cone ring fixedly mounted on the bottom of the inner side of the hollow sandwich limiting cylinder, and a plurality of sinking tubes fixedly fitted on the top of the housing, the bottom end of the sinking tubes being connected to a ring. The casing has a drain pipe at its bottom, a container frame fixedly installed at the bottom of its inner cavity, an air inlet pipe connected to the inside of the hollow sandwich limiting cylinder, a dust filter box connected to the end of the air inlet pipe away from the hollow sandwich limiting cylinder, several dust filter plates movably inserted into the inside of the dust filter box, a connecting pipe connected to the bottom of the dust filter box, an air pump connected to the other end of the connecting pipe, an air outlet pipe connected to the output end of the air pump, a grinding motor fixedly installed at the bottom of the inner cavity, a sealed bearing movably sleeved on the outside of the output end of the grinding motor, a grinding disc connected to the top of the output end of the grinding motor, and a detachable back plate movably installed on the back of the casing by bolts.

[0006] Preferably, both the hollow sandwich limiting cylinder and the conical eave are hollow sandwich structures, the conical eave is an inwardly expanding annular structure, and the bottom of the inner cavity of the hollow sandwich limiting cylinder is arc-shaped.

[0007] Preferably, the sealed bearing is fixedly sleeved on the top of the housing, and the output end of the grinding motor passes through the housing through the sealed bearing and extends to the inner side of the hollow sandwich limiting cylinder. The grinding disc and the hollow sandwich limiting cylinder are concentric circles.

[0008] Preferably, the sinking tube is fixedly inserted through the shell and connected to the bottom of the hollow sandwich limiting cylinder cavity. The sinking tube is evenly distributed in a circle on the inner side of the shell and the hollow sandwich limiting cylinder. The end of the drainage tube away from the ring tube corresponds to the position of the top of the container placement frame.

[0009] Preferably, the guide holes are evenly distributed circumferentially inside the inner wall of the conical eaves, the air outlet pipe is fixedly inserted through the shell and connected to the outside of the shell, the connecting pipe is connected to the bottom of the dust filter box cavity, the air inlet pipe is fixedly inserted through the shell and connected to the top of the dust filter box cavity, the air inlet pipe is connected to the hollow part of the hollow interlayer limiting cylinder, and the air pump and the dust filter box are both fixedly installed at the bottom of the shell cavity.

[0010] Preferably, a control panel is fixedly mounted on the front of the housing.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this structure, the user places the optical fiber to be polished into the inner side of the optical fiber clamp and clamps it in place. Then, the high-precision electronically controlled telescopic rod is activated to extend and the optical fiber contacts the top of the polishing disc. At this time, the polishing motor is started to rotate, which drives the polishing disc to rotate, thereby polishing the end face of the optical fiber. As the polishing proceeds, dust is generated. At this time, the air pump is activated, which applies negative pressure to the connecting pipe and the dust filter box. The sealed airflow inside the dust filter box enters through the air inlet pipe and exhausts the airflow inside the hollow interlayer limiting cylinder and the conical eaves. The airflow enters through the guide hole and guides the dust and airflow into the dust filter box. After being filtered by the dust filter plate, the air pump extracts the airflow and discharges it to the outside of the shell through the air outlet pipe, which avoids dust overflow and increases the environmental protection effect.

[0012] In this invention, when the optical fiber is polished with polishing fluid at the top of the polishing disc, excess polishing fluid is guided into the hollow sandwich limiting cylinder. It then flows down the inside of the hollow sandwich limiting cylinder, is guided by the flow guide cone ring, enters the sinking pipe, and is converged by the ring pipe. Finally, it is guided through the drainage pipe into the return container placed inside the container placement frame for easy recycling. Furthermore, when cleaning the inside of the hollow sandwich limiting cylinder, the water flow is discharged through this channel, facilitating recycling and cleaning, thus increasing the convenience of use.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: an end-face grinding device for optical fiber processing, including a housing 1, a gantry 3 fixedly installed on the top of the housing 1, a sliding sleeve 5 slidably sleeved on the outer side of the top of the gantry 3, a high-precision electrically controlled telescopic rod 6 fixedly installed at the bottom of the sliding sleeve 5, an optical fiber clamp 7 fixedly installed at the output end of the high-precision electrically controlled telescopic rod 6, a hollow sandwich limiting cylinder 4 fixedly installed on the top of the housing 1, a conical eave 20 fixedly installed on the top of the hollow sandwich limiting cylinder 4, a plurality of guide holes 19 opened inside the conical eave 20, a guide cone ring 21 fixedly installed at the bottom of the inner side of the hollow sandwich limiting cylinder 4, a plurality of sinking tubes 22 fixedly sleeved on the top of the housing 1, the bottom end of the sinking tubes 22 connected to a ring tube 23, and the bottom of the ring tube 23... A drainage pipe 24 is connected to the bottom of the inner cavity of the housing 1. A container placement frame 18 is fixedly installed at the bottom of the inner cavity of the housing 1. An air inlet pipe 10 is connected to the inside of the hollow interlayer limiting cylinder 4. One end of the air inlet pipe 10 away from the hollow interlayer limiting cylinder 4 is connected to a dust filter box 16. Several dust filter plates 17 are movably inserted into the inside of the dust filter box 16. A connecting pipe 15 is connected to the bottom of the dust filter box 16. The other end of the connecting pipe 15 is connected to a vacuum pump 14. The output end of the vacuum pump 14 is connected to an air outlet pipe 9. A grinding motor 12 is fixedly installed at the bottom of the inner cavity of the housing 1. A sealed bearing 13 is movably sleeved on the outside of the output end of the grinding motor 12. A grinding disc 11 is drivenly connected to the top of the output end of the grinding motor 12. A detachable back plate 8 is movably installed on the back of the housing 1 by bolts.

[0020] The working principle of the above technical solution is as follows: During use, the user places the optical fiber to be polished into the inner side of the optical fiber clamp 7 and clamps it in place. Then, the high-precision electrically controlled telescopic rod 6 is activated to extend and the optical fiber contacts the top of the polishing disc 11. At this time, the polishing motor 12 is started to rotate, which drives the polishing disc 11 to rotate, thereby polishing the end face of the optical fiber. As the polishing is carried out, dust is generated. At this time, the air pump 14 is activated. The air pump 14 applies negative pressure to the connecting pipe 15 and the dust filter box 16. The sealed airflow inside the dust filter box 16 enters through the air inlet pipe 10 and discharges the airflow inside the hollow interlayer limiting cylinder 4 and the conical eaves 20. The airflow enters through the guide hole 19 and guides the dust and airflow into the dust filter box 16. After being filtered by the dust filter plate 17, the air pump 14 extracts the airflow and discharges it to the outside of the housing 1 through the air outlet pipe 9, which avoids dust overflow and increases the environmental protection effect.

[0021] In another implementation scheme, such as Figures 1-4 As shown, both the hollow sandwich limiting cylinder 4 and the conical eave 20 are hollow sandwich structures. The conical eave 20 is an inwardly expanding annular structure, and the bottom of the inner cavity of the hollow sandwich limiting cylinder 4 is arc-shaped.

[0022] The hollow interlayer in the middle of the hollow interlayer limiting cylinder 4 and the conical eave 20 facilitates airflow guidance, thereby facilitating airflow discharge, increasing relative stability, and making it easier for airflow to pass through. The structure of the conical eave 20 expanding inward towards the center facilitates the formation of an airflow discharge extension at the top of the hollow interlayer limiting cylinder 4, which facilitates the discharge of airflow and dust and reduces overflow.

[0023] In another implementation scheme, such as Figures 1-3 As shown, the sealed bearing 13 is fixedly sleeved on the top of the housing 1. The output end of the grinding motor 12 passes through the housing 1 through the sealed bearing 13 and extends to the inner side of the hollow sandwich limiting cylinder 4. The grinding disc 11 and the hollow sandwich limiting cylinder 4 are concentric circles.

[0024] The sealed bearing 13 limits the output shaft of the grinding motor 12 and facilitates the operation of the structure.

[0025] In another implementation scheme, such as Figures 1-4 As shown, the sinking pipe 22 is fixedly inserted through the shell 1 and connected to the bottom of the inner cavity of the hollow interlayer limiting cylinder 4. The sinking pipe 22 is evenly distributed in a circle on the inner side of the shell 1 and the hollow interlayer limiting cylinder 4. The end of the drainage pipe 24 away from the ring pipe 23 corresponds to the position of the top of the container placement frame 18.

[0026] When the optical fiber is polished with polishing fluid at the top of the polishing disc 11, excess polishing fluid will be guided into the hollow sandwich limiting cylinder 4. At this time, it flows down into the hollow sandwich limiting cylinder 4, and is guided by the flow guiding cone ring 21, enters the sinking pipe 22, and is converged by the ring pipe 23, and then guided by the drainage pipe 24 into the return container placed inside the container placement frame 18 for easy recycling. When cleaning the inside of the hollow sandwich limiting cylinder 4, the water will be discharged through this channel, which is convenient for recycling and cleaning, increasing the convenience of use.

[0027] In another implementation scheme, such as Figures 1-4 As shown, the guide holes 19 are evenly distributed in a circle on the inner side wall of the conical eaves 20. The air outlet pipe 9 is fixedly inserted through the housing 1 and connected to the outside of the housing 1. The connecting pipe 15 is connected to the bottom of the inner cavity of the dust filter box 16. The air inlet pipe 10 is fixedly inserted through the housing 1 and connected to the top of the inner cavity of the dust filter box 16. The air inlet pipe 10 is connected to the hollow part of the hollow interlayer limiting cylinder 4. The air pump 14 and the dust filter box 16 are both fixedly installed at the bottom of the inner cavity of the housing 1.

[0028] Start the air pump 14. The air pump 14 applies negative pressure to the connecting pipe 15 and the dust filter box 16. The sealed airflow inside the dust filter box 16 enters through the air inlet pipe 10 and discharges the airflow inside the hollow interlayer limiting cylinder 4 and the conical eaves 20. The airflow enters through the guide hole 19 and guides the dust and airflow into the dust filter box 16. After being filtered by the dust filter plate 17, the air pump 14 extracts the airflow and discharges it to the outside of the housing 1 through the air outlet pipe 9.

[0029] In another implementation scheme, such as Figure 1 As shown, a control panel 2 is fixedly mounted on the front of the housing 1.

[0030] The output of the control panel 2 is electrically connected to the input of the high-precision electric telescopic rod 6, the grinding motor 12 and the air pump 14 via wires, which facilitates the addition of automated control functions and enhances the auxiliary operation effect.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
