Description

Technical Field

[0001] This utility model relates to the field of optical fiber polishing technology, specifically to an optical fiber polishing device. Background Technology

[0002] In today's era of rapid digital information development, optical fiber, as a high-efficiency and high-speed data transmission medium, is constantly expanding its application scope, covering many fields such as communications, medical care, and industrial sensing. Whether in large-scale communication network deployment or miniaturized, personalized optical fiber sensing experiments and innovation projects, the demand for optical fiber processing, especially the polishing of optical fiber end faces, is increasing.

[0003] Professional fiber optic polishing machines can perform high-precision fiber polishing operations, ensuring that the polished fiber end faces are flat and smooth, meeting stringent optical performance requirements. However, these devices are often complex in structure, integrating numerous precision mechanical transmission components, automated control elements, and high-precision polishing disc systems. This results in high manufacturing costs and expensive prices. For many DIY users with limited budgets, such as hobbyists in the field of fiber optic communication, student teams engaged in fiber optic sensing research, or individual entrepreneurs developing small-scale fiber optic application projects, the high procurement costs become a significant barrier, greatly limiting their exploration and innovative practices in the field of fiber optics.

[0004] On the other hand, DIY users typically choose simple polishing equipment, such as homemade hand polishing platforms or inexpensive general-purpose polishing tools, when performing fiber optic polishing. While these devices are inexpensive, their functionality is very limited. The most prominent problem is their inability to switch between different grit counts. In fiber optic polishing, different grit count polishing pads play different roles in removing surface materials and improving surface roughness. From using low-mesh polishing pads to quickly remove larger uneven areas in the coarse polishing stage, to using high-mesh polishing pads to gradually improve the smoothness of the fiber end face in the fine polishing and polishing stages, the precise selection and switching of the polishing pad grit count at each stage is crucial. The lack of this switching capability makes it difficult for DIY users to process fibers according to scientific and standardized polishing procedures, ultimately resulting in inconsistent fiber end face quality after polishing, failing to achieve ideal optical performance indicators, and severely affecting the performance of fibers in practical applications. Therefore, developing a fiber optic polishing device that is both cost-effective and capable of switching between different grit counts has become an urgent task to meet the needs of DIY users and promote the widespread application of fiber optic technology among a wider range of people. Utility Model Content

[0005] The purpose of this invention is to provide an optical fiber polishing device to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] An optical fiber polishing device includes a support mechanism and a polishing mechanism.

[0008] Furthermore, the support mechanism includes a support base with a turntable on its top surface. The support mechanism also includes a first driving member that drives the turntable to rotate. The first driving member includes a rotating shaft rotatably mounted at the center of the support base. The turntable is mounted on the top of the rotating shaft. A first motor is mounted on the outer side of the support base, and a worm gear is connected to the output end of the first motor. A worm wheel is mounted on the outer side of the rotating shaft. The worm gear and worm wheel are meshed together. The worm gear drive has a large transmission ratio, enabling the first motor to output at a relatively low speed to achieve smooth, slow rotation of the turntable, facilitating precise switching between grinding discs of different grit sizes. Simultaneously, the worm gear drive also has a self-locking function, preventing the turntable from rotating unexpectedly due to external forces when the motor stops working, ensuring the stability of the grinding disc position during grinding and improving grinding accuracy.

[0009] Furthermore, the first motor is a servo motor, which has precise control performance and can accurately control the rotation angle and speed of the turntable. When switching grinding discs, it can ensure that the grinding disc stops accurately in the working position, avoiding optical fiber grinding position deviation due to inaccurate positioning; and it can flexibly adjust the rotation speed of the turntable according to different grinding requirements, improving grinding efficiency and quality.

[0010] Furthermore, the grinding mechanism includes four sets of grinding discs, which are equidistantly distributed on the top surface of the turntable. Each of the four grinding discs has polishing paper of different grit sizes adhered to its surface. The grinding mechanism also includes a second driving component that drives any one of the grinding discs to rotate. The second driving component includes a connecting shaft installed at the center of the bottom surface of the four grinding discs, and the connecting shaft is rotatably connected to the turntable. A driven gear is mounted on the outer side of the connecting shaft. A base is installed inside the support, and a second motor is installed inside the base. The output end of the second motor is connected to a driving gear, which meshes with any one of the driven gears. This structural design allows for convenient selection of grinding discs with different grit sizes for operation, meeting the different stages of fiber optic grinding from coarse to fine grinding, and significantly improving the grinding effect. Simultaneously, the gear transmission enables the transmission of a large torque, ensuring stable rotation of the grinding discs and guaranteeing the reliability of the grinding process.

[0011] Furthermore, the driving gear is located between the driven gear and the rotating shaft.

[0012] Furthermore, the support base has several heat dissipation holes on its side. During the operation of the device, the second motor will generate heat. The heat dissipation holes can effectively promote air circulation and dissipate this heat in a timely manner, preventing the device from being damaged or its performance from deteriorating due to overheating, extending the service life of the device, and ensuring stable operation of the device.

[0013] Furthermore, the side of the support base is provided with a wire groove, which can extend the circuit of the second motor to the outside so that the user can supply power to the second motor.

[0014] Compared with existing technologies, the advantages of this invention are as follows: The device is equipped with four sets of polishing discs with different grit numbers of polishing paper adhered to their surfaces, which can be switched by rotating the discs via a first driving component. From the coarse polishing stage, which uses low-grit polishing paper to quickly remove larger uneven parts on the fiber surface, to the fine polishing and polishing stages, which use high-grit polishing paper to gradually improve the smoothness of the fiber end face, this invention can precisely match each stage of fiber polishing, ensuring that the polished fiber end face achieves ideal optical performance indicators. This effectively improves the problem of inconsistent polishing quality previously caused by the inability to switch polishing grit numbers for DIY users. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an optical fiber polishing device, including a support mechanism 100 and a polishing mechanism 200.

[0022] In one embodiment of this utility model, the support mechanism 100 further includes a support base 1001, a turntable 1002 on the top surface of the support base 1001, and a first driving member that drives the turntable 1002 to rotate. The first driving member includes a rotating shaft 1004 rotatably mounted at the center of the support base 1001, the turntable 1002 being mounted on the top of the rotating shaft 1004, and a first motor 1003 mounted on the outer side of the support base 1001. The output end of the first motor 1003 is connected to a worm gear 100. 6. A worm gear 1005 is installed on the outer side of the rotating shaft 1004. The worm 1006 and the worm gear 1005 are meshed together. When the first motor 1003 is turned on, the output shaft of the motor drives the worm 1006 to rotate. The worm 1006 and the worm gear 1005 mesh with each other. Since the worm gear 1005 is installed on the rotating shaft 1004, and the top of the rotating shaft 1004 is connected to the turntable 1002, the rotation of the worm 1006 drives the worm gear 1005 to rotate, thereby causing the turntable 1002 to rotate around the rotating shaft 1004, realizing the switching of different grinding discs 2001.

[0023] In one embodiment of this utility model, the first motor 1003 is further configured as a servo motor. A control signal is sent to the servo motor through a pre-set control program, and the control signal precisely adjusts the rotation angle and speed of the servo motor's output shaft. When it is necessary to switch the grinding disc, the control signal causes the servo motor to drive the worm gear 1006 to rotate by a corresponding angle, thereby causing the turntable 1002 to rotate accurately to the target grinding disc position. During the grinding process, the servo motor speed can also be adjusted in real time according to the actual situation, thereby changing the turntable speed.

[0024] As an embodiment of this utility model, the grinding mechanism 200 further includes four sets of grinding discs 2001, which are equidistantly distributed on the top surface of the turntable 1002. The surfaces of the four sets of grinding discs 2001 are coated with polishing paper of different grit sizes. The grinding mechanism 200 also includes a second driving member, which drives any one of the grinding discs 2001 to rotate. The second driving member includes a connecting shaft 2005 installed at the center of the bottom surface of the four sets of grinding discs 2001, and the connecting shaft 2005 is rotatably connected to the turntable 1002. A driven gear 2006 is installed on the outer side of the connecting shaft 2005. A base 2002 is installed inside the support 1001, and a second motor 2003 is installed inside the base 2002. The output end of the second motor 2003 is connected to a driving gear 2004. The driving gear 2004 is meshed with any one of the driven gears 2006. When the second motor 2003 is started, the motor output shaft drives the driving gear 2004 to rotate. When the driving gear 2004 meshes with a driven gear 2006, the rotation of the driving gear 2004 drives the driven gear 2006 to rotate. Since the driven gear 2006 is mounted on the connecting shaft 2005, and the connecting shaft 2005 is fixed to the polishing disc 2001, the connecting shaft 2005 and the polishing disc 2001 rotate synchronously to achieve the polishing operation of the optical fiber. At the same time, the optical fiber connector has been pre-installed before polishing. Specifically, one end of the optical fiber is passed through the optical fiber connector, so that the optical fiber connector is fixed on the outside of the optical fiber. Then, the outer jacket of the protruding end of the optical fiber is cut off, and then the end face of the protruding optical fiber is polished. The optical fiber can be held by hand or fixed with a special optical fiber clamp. During polishing, special optical fiber polishing fluid also needs to be dripped onto the polishing paper.

[0025] In one embodiment of this utility model, the driving gear 2004 is further located between the driven gear 2006 and the rotating shaft 1004.

[0026] As an embodiment of this utility model, the support base 1001 is further provided with several heat dissipation holes on its side. Utilizing the principle of heat exchange, the heat generated inside the device raises the air temperature. The hot air, which has a lower density, rises and is discharged through the heat dissipation holes. Meanwhile, the cold air outside, which has a higher density, enters the device through the heat dissipation holes, forming natural convection and continuously carrying away the heat inside the device, thus maintaining the internal temperature of the device within a reasonable range.

[0027] As an embodiment of this utility model, the support base 1001 is further provided with a wire groove on its side, which can extend the circuit of the second motor to the outside so that the user can supply power to the second motor.

[0028] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuits of the first motor and the second motor can be implemented by those skilled in the art through simple programming, which is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
