Description

Technical Field

[0001] The invention relates to the technical field of optical fiber grating production, and in particular to a grating production device. Background Art

[0002] Fiber Bragg grating is a diffraction grating formed by periodically modulating the refractive index of the fiber core in the axial direction by a certain method. It is a passive filter device. Its manufacturing method is to use the photosensitivity of the optical fiber material to write the incident light coherent field pattern into the fiber core by ultraviolet light exposure, and produce a periodic change of the refractive index along the axial direction of the core in the fiber core, thereby forming a permanent spatial phase grating. Its function is essentially to form a narrowband (transmission or reflection) filter or reflector in the fiber core. When a beam of wide spectrum light passes through the fiber Bragg grating, the wavelength that meets the fiber Bragg condition will be reflected, and the remaining wavelengths will continue to be transmitted through the fiber Bragg grating. In the prior art, each process of grating production, peeling, cleaning, writing, coating and cutting is mostly separated, which will lead to low production efficiency, high labor costs, and product consistency cannot be guaranteed.

[0053] In one or more embodiments of the present invention, the adjustment assembly 28 includes a slave swivel 29, a mounting plate 30 having the same number as the through holes and corresponding to each other, a main swivel 31 and a second support frame 32, the second support frame 32 is arranged on the workbench 1 and is located on both sides of the main swivel 31, the main swivel 31 is rotatably connected to the second support frame 32, the main swivel 31 is connected to the slave swivel 29 through a connecting piece, the through holes are arranged on the slave swivel 29, the mounting plate 30 is arranged on the inner wall of the slave swivel 29, and a filter is arranged on the mounting plate 30, and the laser emitted by the laser source 27 passes through the through holes and the filter in sequence and irradiates the surface of the optical fiber from which the epidermis has been removed.

[0054] By setting the rotatable main rotating ring 31 and the slave rotating ring 29, the main rotating ring 31 and the slave rotating ring 29 can be rotated according to different grating etching requirements, so that different filters can filter light of different wavelengths in the emitted laser, thereby realizing the switching of gratings of different wavelengths, which is very convenient and enhances the versatility of the entire device.

[0056] In one or more embodiments of the present invention, the coating mechanism includes a raw material bin 33, a heating mechanism 34 and a clamping portion 35 consisting of an upper clamping plate and a lower clamping plate. The heating mechanism 34 is arranged on the workbench 1 through a third support frame 36. The clamping portion 35 is connected and arranged below the heating mechanism 34. The raw material bin 33 is connected and arranged above the heating mechanism 34.

The cutting and traction mechanism drives the optical fiber to pass through the circular groove formed by the lower surface of the upper clamping plate and the upper surface of the lower clamping plate to coat the surface of the optical fiber after grating etching.

[0057] By setting up the heating mechanism 34 of the raw material bin 33, the coating raw material in the raw material bin 33 can be heated and then passed into the clamping part 35, so that when the optical fiber passes through the clamping part 35, the coating can be applied to the part of the optical fiber where the skin is removed, thereby completing the processing of the grating.

[0058] In the embodiment of the present invention, the raw material in the raw material bin is polyethylene, which is heated by the heating mechanism to form a liquid, and enters the clamping part 35 through the pipeline, is coated on the part of the optical fiber where the skin is removed, and forms a transparent coating.

[0059] In practice, magnetic blocks are provided at corresponding positions on the upper clamping plate and the lower clamping plate, respectively. When the upper clamping plate and the lower clamping plate are brought close to each other, the upper clamping plate and the lower clamping plate are automatically attracted together through the magnetic blocks and the optical fiber is clamped. When the optical fiber needs to be placed, the upper clamping plate and the lower clamping plate are separated, and the optical fiber is placed in the semicircular groove on the lower clamping plate, and the upper clamping plate is covered so that the optical fiber is clamped.

[0060] like Figure 6As shown, in one or more embodiments of the present invention, the cutting and traction mechanism includes a driving motor 37, a fourth support frame 38, two rotating wheels 39, a linkage mechanism and a cutter mechanism, the fourth support frame 38 is arranged at the other end of the workbench 1, the two rotating wheels 39 are arranged side by side on one side of the fourth support frame 38, and the optical fiber passes between the two rotating wheels 39, and the cutter mechanism is arranged on the above-mentioned fourth support frame 38, the driving motor 37 is transmission-connected with the linkage mechanism, and the linkage mechanism is transmission-connected to the rotating wheel 39 and the cutter mechanism respectively, and can drive the two rotating wheels 39 to pull the optical fiber located therebetween, and can periodically drive the cutter mechanism to cut the optical fiber passing through between the two rotating wheels 39, and at the same time, the linkage mechanism can periodically drive the connecting frame 18 to move toward the side away from the fiber winding mechanism.

[0061] By setting the driving motor 37 and the linkage mechanism, the driving motor 37 can drive the linkage mechanism to drive the two rotating wheels 39 to rotate, thereby pulling the optical fiber. At the same time, the linkage mechanism also drives the cutter mechanism to cut the optical fiber passing through the two rotating wheels 39 to obtain the final optical fiber grating product. In addition, the linkage mechanism can periodically drive the connecting frame 18 to move toward the side away from the fiber winding mechanism to ensure that the fiber stripping mechanism periodically peels the optical fiber.

[0062] In one or more embodiments of the present invention, the linkage mechanism includes three transmission gears 40, two linkage gears 41 and a linkage disk 42 with a U-shaped cross-section. The two transmission gears 40 are rotatably arranged on the other side of the fourth support frame 38 and are connected one-to-one with the two rotating wheels 39. Another transmission gear 40 is arranged on one side of the fourth support frame 38. The two linkage gears 41 are respectively arranged on two sides of the fourth support frame 38 and mesh with one transmission gear 40 on the corresponding side. The linkage disk 42 is slidably arranged on the workbench 1 through a second return spring and is located at the corresponding Below the linkage gear 41, a stopper 43 abutting against the connecting frame 18 is provided on the linkage disk 42, and racks are respectively provided on the end faces of both ends of the linkage disk 42. An arc segment gear is provided on the outer wall of the linkage gear 41, and the arc segment gear is meshed with the corresponding rack on the linkage gear 41. When the driving motor 37 drives the transmission gear 40 to drive the linkage gear 41 to rotate, the arc segment gear on the linkage gear 41 drives the linkage disk 42 to periodically reciprocate, and the linkage disk 42 drives the stopper 43 to periodically drive the connecting frame 18 to move toward the side away from the fiber winding mechanism.

[0063] By setting the transmission gear 40, on the one hand, the two rotating wheels 39 can be driven to drive the optical fiber, and on the other hand, the transmission gear 40 drives the arc segment gear on the linkage gear 41 to drive the linkage disk 42 to periodically reciprocate, so that the fiber stripping mechanism can periodically strip the optical fiber. Here, the arc segment gear adopts a quarter arc shape.

[0064] In one or more embodiments of the present invention, the cutter mechanism includes a cutter seat 44 of a frame-shaped structure, and the optical fiber passing through between the two rotating wheels 39 passes through the cutter seat 44. A cutter 45 is arranged in the cutter seat 44, and cutting grooves matching the cutter 45 are arranged on the inner walls on the opposite sides of the cutter seat 44. The cutter 45 is slidably arranged in the cutting groove through a fourth slide rod 46. A section of the fourth slide rod 46 away from the cutter 45 passes through the side wall of the cutter seat 44 and is connected to a wedge block 47. A second linkage rod 48 is arranged on the linkage disk 42, and one end of the second linkage rod 48 away from the linkage disk 42 abuts against the inclined surface of the wedge block 47. The linkage disk 42 can drive the second linkage rod 48 to move periodically, and the second linkage rod 48 can periodically drive the wedge block 47 to drive the cutter 45 to complete the cutting of the optical fiber in the cutter seat 44.

[0065] The linkage disk 42 drives the wedge block 47 through the second linkage rod 48 to periodically drive the cutter 45 to complete the cutting of the optical fiber in the cutter seat 44, thereby achieving fiber stripping and cutting synchronization. In order to enable the second linkage rod 48 to periodically drive the wedge block 47 to drive the cutter 45 to complete the cutting of the optical fiber in the cutter seat 44, it is necessary to set a fourth reset spring on the fourth slide bar 46, so that when the second linkage rod 48 can periodically drive the wedge block 47 to drive the cutter 45 to complete the cutting of the optical fiber in the cutter seat 44, after the linkage disk 42 is reset, the driving force of the second linkage rod 48 on the wedge block 47 disappears, and the fourth reset spring drives the wedge block 47 to reset.

[0066] When in use, firstly, the rotating disk 2 is placed in the slide groove 3, and the rotating disk 2 drives the slide groove 3 to compress the first spring 8 downward, and the second spring 10 in the stretched state drives the first sliding frame 4 to move toward the direction of the slide groove 3, and the upper ends of the first sliding frames 4 located on both sides of the rotating disk 2 clamp the rotating disk 2, and then one end of the optical fiber passes through between the two positioning wheels, the aligner, the two scrapers 17, the two cleaning blocks 26, the slave rotating ring 29, the main rotating ring 31, the clamping part 35, the two rotating wheels 39 and the cutter seat 44, and then the protective cover 11 is rotated to cover the rotating disk 2. At this time, the baffle 12 on the protective cover 11 abuts against the first linkage rod 20, and can drive the first linkage rod 20 to drive the driving frame 21 to move toward one side of the writing mechanism, and the second inclined sections on both sides of the driving frame 21 drive the third sliding frame 25 to drive the corresponding cleaning block 26 to approach and clamp the light. At this time, the slave rotating ring 29 is rotated first, so that the corresponding filter and through hole correspond to the laser head of the laser source 27. Simultaneously, the heating mechanism 34 heats the paint.

[0067] Then start the driving motor 37, the driving motor 37 drives the transmission gear 40 to drive the linkage gear 41 to rotate, the linkage gear 41 drives the two rotating wheels 39 to pull the optical fiber located therebetween, and at the same time the arc segment gear on the linkage gear 41 drives the linkage disk 42 to periodically reciprocate, the linkage disk 42 drives the block 43 to periodically drive the connecting frame 18 to move toward the side away from the fiber winding mechanism, so that the first inclined section on the connecting frame 18 drives the second sliding frame 16 to drive the scraper 17 to periodically peel the optical fiber, thereby completing the preparation work before grating etching.

[0068] The stripped optical fiber continues to move forward and is cleaned by two cleaning blocks 26 clamped together.

[0069] Subsequently, the optical fiber moves forward into the rotating ring 29, and the laser emitted from the laser head of the laser source 27 performs grating etching on the peeled fiber core. After the etching is completed, the optical fiber continues to move forward into the clamping part 35, and the heated and melted coating in the heating mechanism 34 enters the clamping part 35. When the optical fiber passes through the clamping part 35, the coating can be applied to the part of the optical fiber where the epidermis is removed.

[0070] Finally, the optical fiber continues to move forward into the cutter seat 44. Since the arc segment gear on the linkage gear 41 drives the linkage disk 42 to periodically reciprocate, the linkage disk 42 can drive the second linkage rod 48 to periodically move. The second linkage rod 48 can periodically drive the wedge block 47 to drive the cutter 45 to complete the cutting of the optical fiber in the cutter seat 44.

[0071] The whole process is carried out in a cycle, thereby completing the continuous grating etching of the optical fiber on the rotating disk 2.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
