Technical Field

[0001] The utility model relates to the technical field of optical fiber head coating auxiliary devices, in particular to an optical fiber head coating limiting device. Background Art

[0002] Optical fiber, as the primary medium for optical waveguides, is currently widely used in various fields, including fiber-optic communication transmission, fiber laser manufacturing, semiconductor laser fiber coupling output, and medical laser cosmetic equipment. The coating industry applies various types of optical thin films to the end faces of optical fibers, such as anti-reflection (anti-reflection) coatings, bandpass coatings, high-reflection coatings, and long-wave (short-wave) cutoff coatings. Optical coatings can also improve the wear and corrosion resistance of optical fiber tips, extending their service life. By depositing multiple layers of dielectric coatings on the end faces of optical fiber tips, various spectral requirements can be achieved.

[0003] Fiber optic products consist of fiber optic heads and optical fibers. The fiber optic head is a round glass column with a diameter of 1-3mm, and the optical fiber is a fiber coil bundled together with a length of 0.5-1m. The main difficulty with existing fiber optic head coating is that it cannot meet the demand for simultaneous coating of large quantities of fiber optic heads. Coating needs to be carried out in batches, and the coating efficiency is low. Utility Model Content

[0004] The purpose of the utility model is to provide an optical fiber head coating limiting device, which can limit a large number of optical fiber heads at the same time and meet the demand for simultaneous coating of a large number of optical fiber heads.

[0005] The technical solution of this utility model:

[0006] A fiber optic head coating limiting device includes a mounting seat, a plurality of strip grooves are horizontally opened on the top of the mounting seat, and a plurality of placement holes for the columns of the fiber optic heads to pass through are longitudinally opened in the strip grooves. Each row of fiber optic heads is limited by a slide, and the slides are fitted together in pairs; the slide has a plurality of limiting grooves; after the columns of the fiber optic heads pass through the placement holes, they are clamped in the strip grooves by the outer protrusions of the fiber optic heads, and finally blocked above the outer protrusions of the fiber optic heads by the limiting grooves on the slide.

[0007] Furthermore, the left and right ends of the top of the mounting seat are provided with limit plates, and the slide plate is located between the two limit plates; the top of the mounting seat is provided with a pressure plate with an open middle portion, and the top four corners of the pressure plate are connected to the mounting seat by bolts;

[0008] The front end of the pressure plate is provided with a butterfly bolt, the rear end of which penetrates the pressure plate and extends to the front side of the front slide; the rear end of the pressure plate is provided with a spring plunger, the front end of which penetrates the pressure plate and extends to the rear side of the rear slide;

[0009] The butterfly bolt rotates backward to squeeze the front slide, and all slides move backward so that the limit groove blocks the outer convex part of the optical fiber head, and the rear slide squeezes the spring plunger so that the butterfly bolt and the spring plunger clamp the slide.

[0010] Furthermore, there are two mounting seats, both of which are arranged on a base.

[0011] Furthermore, a plurality of support rods are longitudinally arranged above the base, and both left and right ends of the support rods are fixed to the base via fixing rods, and a plurality of hooks are fixed on the support rods.

[0012] Furthermore, the lower end of the fixing rod is threadedly connected to the base, and the upper end passes through the support rod and is fixed by a nut.

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-Figure 5 As shown, the present invention provides a first embodiment of a fiber optic head coating position limiting device, comprising a mounting base 1 having a plurality of strip-shaped grooves 101 transversely defined on the top of the mounting base 1. A plurality of placement holes 102 are longitudinally defined within the strip-shaped grooves 101 for the columns 301 of the fiber optic heads 3 to pass through. Each row of fiber optic heads 3 is position-limited by a slide 2, with two slides 2 aligned with each other. The slide 2 has a plurality of position limiting grooves, the number of which is the same as the number of fiber optic heads 3 in each row. The position limiting grooves include a placement groove 201 at the rear end and a retaining groove 202 at the front end. The placement groove 201 is for the columns 301 of the fiber optic heads 3 to pass through, while the retaining groove 202 is for blocking the outer protrusion 302 of the fiber optic heads 3. After passing through the placement holes 102, the columns 301 of the fiber optic heads 3 are retained within the strip-shaped grooves 101 by the outer protrusion 302 of the fiber optic heads 3. Finally, the position limiting grooves on the slide 2 are positioned above the outer protrusion 302 of the fiber optic heads 3, thereby limiting the position of the fiber optic heads 3.

[0027] It should be noted that, since in the actual coating process, the optical fiber head 3 is placed on the coating umbrella stand, and then the coating umbrella stand is rotated to perform coating, it is not necessary to fix the optical fiber head 3, and only a simple limit is required. The strip groove 101 is used to accommodate the optical fiber head 3, and the card groove 202 is used to block the outer protrusion 302 of the optical fiber head 3 to prevent the optical fiber head 3 from falling out of the coating umbrella stand during the rotary coating. Therefore, the utility model only limits the optical fiber head, not fixes it.

[0028] The left and right ends of the top of the mounting base 1 are each provided with a limit plate 103. The slide plate 2 is located between the two limit plates 103, and the top of the slide plate 2 is lower than the top of the limit plate 103, which can play a role in limiting and guiding the slide plate 2 when it slides. The top of the mounting base 1 is provided with a pressure plate 4 with an open middle portion. The four corners of the top of the pressure plate 4 are connected to the mounting base 1 by bolts 5. The left and right sides of the pressure plate 4 are respectively pressed on the two limit plates 103.

[0029] The front end of the pressure plate 4 is provided with two butterfly bolts 6, the rear ends of which penetrate the pressure plate 4 and extend to the front side of the front slide 2. The pressure plate 4 has threaded holes that match the butterfly bolts 6; the rear end of the pressure plate 4 is provided with two spring plungers 7, the front ends of which penetrate the pressure plate 4 and extend to the rear side of the rear slide 2.

[0030] The butterfly bolt 6 is rotated backward to squeeze the front end slide 2, causing the front end slide 2 to move backward. Since the slides 2 fit together, all the slides 2 move backward, so that the slots 202 on all the limit grooves are blocked above the outer protrusions 302 of the optical fiber head 3, playing a limiting role; and the rear end slide 2 squeezes the spring plunger 7, so that the butterfly bolt 6 and the spring plunger 7 clamp the slide 2 to prevent the slide 2 from shifting.

[0031] The working principle of this embodiment is as follows: the column 301 of the optical fiber head 3 is inserted into the placement hole 102, and the outer protrusion 302 of the optical fiber head 3 is pressed on the bottom of the strip groove 101, so that the optical fiber head 3 can be prevented from continuing to move downward, and then the butterfly bolt 6 is rotated backward to squeeze the front slide 2 so that the front slide 2 moves backward, so that all slides 2 move backward, so that the card grooves 202 on all the limit grooves are blocked above the outer protrusion 302 of the optical fiber head 3, which plays a limiting role; then the limiting device is placed on the coating umbrella stand for coating. After the coating is completed, the limiting device is taken out, the butterfly bolt 6 is unscrewed, the spring plunger 7 pushes the slide 2 open, and the optical fiber head 3 can be taken out in turn.

[0032] like Figure 6 As shown, based on the first embodiment, the utility model provides a second embodiment of the optical fiber head coating limit device, the number of the mounting base 1 is two, both are arranged on a base 8, and can be easily installed on the coating umbrella stand of the flat coating machine through the base 8, which is convenient for subsequent coating.

[0033] like Figure 7 As shown, based on the second embodiment, the utility model provides a third embodiment of the optical fiber head coating limiting device, a plurality of support rods 10 are longitudinally arranged above the base 8, and the left and right ends of the support rods 10 are fixed to the base 8 through fixing rods 9, and a plurality of hooks 11 are fixed on the support rods 10, and the hooks 11 are used to place the fiber coil 303 of the optical fiber head 3.

[0034] It should be noted that in order to clearly express the structure in the figure, Figure 7 Only the fiber coil 303 of one optical fiber head 3 is shown.

[0035] Based on the third embodiment, the present invention provides a fourth embodiment of a fiber head coating limiting device. The lower end of the fixing rod 9 is threadedly connected to the base 8, and the upper end passes through the support rod 10 and is fixed by a nut 13. The lower end of the fixing rod 9 has a lower thread, and the base 8 has a matching screw hole 801, which facilitates the assembly and disassembly of the fixing rod 9. The top of the fixing rod 9 has a limiting block 12, and the upper end of the fixing rod 9 has an upper thread that matches the nut 13. The nut 13 and the limiting block 12 can clamp the support rod 10 between them, making it easy to assemble and disassemble.

[0036] The above description is only a preferred embodiment of the present invention and should not be understood as limiting the present application. All equivalent changes and modifications made within the scope of the patent application of the present invention should fall within the scope of the present invention.
