Description

(1) Technical Field

[0001] The present invention relates to a multi-wheel turntable type optical fiber side polishing device, belonging to the field of optical fiber micro-processing devices. (2) Background Art

[0002] Optical fiber side polishing is an optical fiber micro-processing technology for side polishing optical fibers, which means polishing the optical fiber to a specified depth from the side of the optical fiber. When the optical fiber cladding or core is polished to a certain depth, the ability of the optical fiber to confine the optical field in the core will be weakened, so that the evanescent field can penetrate through the remaining cladding or directly interact strongly with the external environment behind the side polished surface, such as reflection, scattering, absorption, etc. Accordingly, secondary material addition and subtraction processing can be carried out on the side polished surface of the optical fiber, such as coating to produce the SPR effect, coating environment-sensitive materials to make sensors, fitting the side polished surfaces of two optical fibers to make couplers, and using two-photon polymerization technology or femtosecond laser processing technology to process high-precision optical structures on the side polished surface.

[0003] Precisely because side polished optical fibers are pre-devices for a large number of optical fiber devices and have very broad application prospects, realizing the stable, efficient and batch preparation of side polished optical fibers while ensuring processing accuracy is of extremely important significance for the commercial application of optical fiber devices based on side polished optical fibers.

[0004] Currently, the methods for side polishing optical fibers mainly fall into two categories. One is to fix both ends of the optical fiber and polish the side by attaching sandpaper to a roller. The other category is to fix the side polished section of the optical fiber, such as embedding it in a groove or fixing it with epoxy resin for side polishing. The first category of methods uses a polishing roller with a cantilever beam structure, such as patent CN111596407B. When the roller rotates, since the device does not have a buffer structure, during actual polishing, the motor jitter will inevitably be transmitted to the roller and the optical fiber, affecting the polishing quality, and the way of fixing the sandpaper to the polishing wheel is also an important factor affecting the side polishing quality of the optical fiber. The second category of methods uses a groove fixing method, such as patent 201920119607.X, which uses a wide groove for fixing and a cantilever beam type transmission grinding belt for side polishing. It has a great improvement compared with the traditional groove fixing side polishing method, but it is not easy to ensure the stability of the optical fiber in a wide groove. After the fixing glue solidifies, residual stress is likely to remain. When the optical fiber is side polished to break the cylindrical structure, the release of the residual stress will cause the side polished section of the optical fiber to break. Moreover, it is difficult to fix the sandpaper tightly with the transmission grinding belt. If the interface of the spliced sandpaper is uneven, it will affect the side polishing result. This method is also not suitable for batch side polishing of optical fibers. The undulation degree of the transmission grinding belt is relatively large, and it is difficult to simultaneously take into account the heights of the optical fibers in multiple micro-grooves, resulting in inconsistent side polishing depths of the optical fibers. To solve the above technical problems, there is an urgent need for an optical fiber side polishing device that solves the problems of frequent sandpaper replacement, batch polishing of optical fibers, and unstable rotation of the polishing wheel during the polishing process. (3) Summary of the Invention

[0017] As a preferred technical solution, the coordinated cooperation of the polishing device and the optical fiber clamping device realizes semi-automatic batch polishing of optical fibers.

[0018] The structure for specifically realizing the beneficial effects of the present invention is described as follows:

[0019] The multi-wheel turntable type optical fiber side polishing device is as Figures 1 to 12 As shown together, it includes a main body frame, a polishing device and an optical fiber clamping device; the main components in the polishing device are the sandpaper installation structure, the multi-wheel structure and the transmission structure; the main components in the optical fiber clamping device are the optical fiber loading structure and the optical fiber tension adjustment structure. The part arrangement structure of the multi-wheel turntable type optical fiber side polishing device is as follows: the polishing wheel 201 is sleeved into the bearing holes 302 and 306 by the polishing wheel tail handle 206 and is constrained on the I-shaped double disc 300. The driven rubber roller 207 is fixed on the polishing wheel tail handle 206. Multiple polishing wheels are fixed on the I-shaped double disc 300 in the same way. The driving rubber roller 308 is fixed on the transmission shaft 309. At this time, the polishing wheel part 200 is as Figure 8As shown in the figure; the rotating shaft 310 is inserted into the rotating shaft hole 303, and the I-shaped double disc 300 is constrained in the main body frame 100 by the main body frame one 101 and the main body frame three 103. The transmission shaft 309 is constrained in the main body frame 100 by the main body frame three 103 and the main body frame five 105; the rotating motor 402 is connected to the rotating shaft 310 by the coupling 405, and the polishing motor 403 is connected to the transmission shaft 309 by the flexible coupling 406; the optoelectronic switch 401 is fixed on the main body frame two 102; the above polishing device is installed on the electric slide table one 404. The multi-fiber fixture one 501 is arranged on the left side of the substrate 508 and the left side of the polishing wheel one 209. The V-groove wheel set one 502 is arranged in the middle of the substrate 508 and the right side of the polishing wheel one 209. The electric slide table two 507 is arranged on the right side of the substrate 508. The V-groove wheel set two 505 and the multi-fiber fixture two 506 are arranged on the electric slide table 507; the V-groove wheel set basket 503 is arranged in the middle of the V-groove wheel set one 502 and the V-groove wheel set two 505, and the counterweight 504 is arranged in the V-groove wheel set basket 503; the above fiber clamping devices are all installed on the electric slide table three 509. The computer 600 is connected to and controls the optoelectronic switch 401, the rotating motor 402, the polishing motor 403, the electric slide table one 404, the electric slide table two 507 and the electric slide table three 509.

[0020] The sandpaper installation structure is as Figure 6 shown. The one-way bearing 205 is embedded in the bottom of the hollow column cavity of the head of the polisher 201. One end of the sandpaper roller 203 is sleeved into the one-way bearing 205, and one end is constrained by the cover plate 202; both ends of the long strip sandpaper extend into the hollow column cavity of the polisher 201 along the sandpaper seam 204 and are pasted on the sandpaper roller 203. Rotating the sandpaper roller 203 can lock the sandpaper on the surface of the polishing wheel one 209. Since the sandpaper is not directly attached to the surface of the polishing wheel, it effectively solves the problem of the height difference of the sandpaper caused by different adhesive heights, incomplete or excessive surrounding of the polishing wheel surface by the sandpaper, and can avoid the problem of fiber jitter during polishing, which affects the polishing quality.

[0021] The multi-wheel structure is as Figure 7 and Figure 8 shown. The sandpapers are installed on the polishing wheel one 209 to the polishing wheel four 208 in decreasing order of roughness. When the I-shaped double disc 300 rotates one week, the sandpapers can sequentially complete the rough polishing, transitional polishing, fine polishing and polishing processes on the fiber, solving the problem of repeatedly lifting the polishing wheel to replace the sandpaper during the polishing process.

[0022] The transmission structure is as Figure 3 and Figure 8As shown, the polishing motor 403 drives the transmission shaft 309 to rotate through a flexible coupling 406. When the driving rubber roller 308 contacts the driven rubber roller III 207, the transmission shaft 309 drives the driven rubber roller III 207 to rotate, and the driven rubber roller III 207 drives the polishing wheel III 201 to rotate, realizing the polishing of the optical fiber. Since the polishing motor does not directly drive the polishing wheel, it can avoid the eccentric rotation of the polishing wheel caused by the non - coincidence of the central axes of the motor and the polishing wheel. In addition, the transmission structure uses the method of rubber roller fitting, which can also reduce the transmission of motor jitter to the polishing wheel and the optical fiber, thereby improving the polishing quality.

[0023] The optical fiber loading structure is as Figures 9 to 12 shown. One end of X multiple optical fibers 510 is installed in the multi - fiber fixture I 501, and the other ends of the multiple optical fibers 510 pass through the V - groove wheel set I 502, the V - groove wheel set basket 503, and the V - groove wheel set II 505 in sequence, and finally are installed in the multi - fiber fixture II 506. At this time, the V - groove wheel set basket 503 should be located on the substrate 508, and the electric slide II 507 should be located at the leftmost end. Specifically as Figure 10 shown. In the multi - fiber fixture I 501 and the multi - fiber fixture II 506, the multiple optical fibers 510 are placed in the optical fiber grooves 5012 on the groove base 5011, and the multiple optical fibers 510 are fastened in the optical fiber grooves 5012 using the magnetic cover plate 5013; as Figure 11 shown. In the V - groove wheel set I 502 and the V - groove wheel set II 505, each optical fiber separately occupies the V - groove of a V - groove pulley I 5022 on the pulley set base 5021; as Figure 12 shown, as Figure 12 shown. In the V - groove wheel set basket 503, the counterweight 504 is set in the basket main body 5031, and the multiple optical fibers 510 pass through the V - groove wheel set basket 503, and each optical fiber also separately occupies the V - groove of a V - groove pulley II 5032. The optical fiber loading structure of the two optical fiber fixtures and the three V - groove pulley sets can effectively load multiple optical fibers for batch polishing.

[0024] The optical fiber tension adjustment structure is as Figure 9 、 11 and shown in 12. After all the optical fibers are loaded, the V - groove wheel set basket 503 should be located on the substrate 508 and at the lowest height. When the electric slide II 507 slides to the right end, the multiple optical fibers 510 bent between the two V - groove wheel sets will start to straighten and lift the V - groove wheel set basket 503. Thereafter, when the V - groove wheel set basket 503 is stationary, when the resultant force of the tension F l of the multiple optical fibers 510 on the left side of the V - groove wheel set basket 503 and the tension F r of the multiple optical fibers 510 on the right side of the V - groove wheel set basket 503 balances the gravity G of the V - groove wheel set basket 503, F l can be calculated by Equation 1

[0025] Fl = G / cosθ (1)

[0026] Where θ is the angle by which the optical fiber deviates from the original axis, and θ can be calculated from Equation 2

[0027] θ = cos -1 (d0 / l) (2)

[0028] Where d0 is half of the distance between the two V-groove wheel sets, and l is half of the length of the optical fiber between the two V-groove wheel sets, then

[0029]

[0030] Moreover, when installing the optical fiber, the electric slide table II 507 is always located at the leftmost end, making the length of the optical fiber between the two V-groove wheel sets a fixed value. Therefore, the tension on multiple optical fibers 510 can be calculated from the moving distance d of the V-groove wheel set II 505, that is, the tension F on the optical fiber can be calculated from the moving distance d of the electric slide table II 507 l and the relative tension change amount F d .

[0031]

[0032] This optical fiber tension adjustment structure applies different tensions to the optical fiber according to different polishing stages to change the polishing pressure between the polishing wheel and the optical fiber, which can effectively balance the polishing quality and polishing efficiency.

[0033] Due to the above technical solution, when the device is working, the polishing wheel installed with the sandpaper having the highest roughness is driven to rotate by the I-shaped double disc and positioned to the lowest position by the photoelectric gate to contact the optical fiber. The driven rubber roller gradually contacts the driving rubber roller, driving the polishing wheel to start rotating to polish the optical fiber with a preset polishing pressure. After reaching the predetermined polishing depth, the polishing wheel installed with the sandpaper having the second highest roughness changes the polishing pressure to polish the optical fiber in the same way, and so on until the polishing wheel installed with the sandpaper having the lowest roughness polishes the optical fiber, and then the polishing process ends; The specific beneficial effects of the present invention are as follows

[0034] 1. Multiple polishing wheels are installed with sandpapers of different roughnesses and can be selected and used by installing a double disc, which can solve the problem of frequent sandpaper replacement during the polishing process, improve the optical fiber processing efficiency, and reduce sandpaper loss.

[0035] 2. Both ends of the sandpaper are fixed on the sandpaper roller and locked on the surface of the polishing wheel by a one-way bearing arranged at the bottom of the hollow column cavity at the head of the polishing wheel, avoiding the situation that the surface of the polishing wheel fluctuates greatly due to the sandpaper sticking, missing, or overlapping, resulting in high-frequency jitter of the optical fiber during polishing, affecting the polishing quality and even causing optical fiber breakage, and improving the yield rate.

[0036] 3. The polishing motor drives the driving rubber roller through a flexible coupling. The driving rubber roller drives the driven rubber roller through a hollow rubber roller, and the driven rubber roller drives the polishing wheel to rotate. The multi-stage shock-absorbing transmission method can effectively prevent the vibration of the polishing motor from being transmitted to the polishing wheel and the optical fiber, affecting the polishing accuracy.

[0037] 4. The optical fiber loading and optical fiber tension adjustment structure of two optical fiber clamps and a three-V-groove pulley group can effectively balance the polishing quality and polishing efficiency in the case of batch polishing. (IV) BRIEF DESCRIPTION OF THE DRAWINGS

[0068] Subsequently, the computer 600 controls the first electric slide table 404 to stop moving, drives the I-shaped double disc 300 to rotate, and controls the second electric slide table 507 to move a preset distance d4. When the fourth polishing wheel 208 rotates to the lowest point, it drives the rubber roller 308 to contact the fourth driven rubber roller 211, and drives the fourth polishing wheel 208 to rotate. The fourth polishing wheel 208 contacts multiple optical fibers 510.

[0070] Subsequently, the optical fiber is removed, and then the "optical fiber polishing can be ended", obtaining a batch of side-polished optical fibers with the same polishing depth and a flat side-polished surface.
