Description

Technical Field

[0001] This utility model relates to a FA all-convex fiber grinding device. Background Technology

[0002] Optical fiber is a type of fiber made of glass or plastic that serves as a means of light transmission. Its core structure typically consists of a core, cladding, and coating. The core has a higher refractive index than the cladding, allowing light to travel within the core via total internal reflection.

[0003] Optical fibers can be classified into single-mode fiber and multimode fiber according to their transmission mode. Single-mode fiber has a small core diameter and a long transmission distance, making it suitable for long-distance communication; multimode fiber has a larger core diameter and a shorter transmission distance, and is often used in short-distance scenarios such as local area networks.

[0004] Today, optical fiber occupies a central position in the communications field, supporting global internet, telephone, and cable television services, and boasts advantages such as large transmission capacity, low loss, and resistance to electromagnetic interference. Furthermore, it has wide applications in fields such as medicine, sensing, and laser technology, making it a crucial infrastructure for the information age.

[0005] In current fiber polishing methods, directly polishing the fiber using bare fiber polishing equipment is inefficient; applying protective adhesive and then polishing directly using a 380 ring polisher results in low yield but also many defective convex fibers.

[0006] Therefore, a FA (fine grinding) full convex fiber grinding device is proposed to address the above problems. Utility Model Content

[0007] The purpose of this invention is to overcome the existing defects and provide a FA all-convex fiber grinding device with high grinding yield and no chipping.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a FA fully convex fiber polishing device, comprising a base, on which multiple horizontally arranged V-grooves are formed; a groove is formed at the front end of the base; an optical fiber is placed in each of the V-grooves; an upper cover plate is connected to the middle of the base to press down the middle of the multiple optical fibers; and a front cover plate is connected to the front end of the base to press down the front end of the multiple optical fibers.

[0009] Preferably, the upper cover plate is fixed to the middle of the upper end face of the base by applying FA adhesive; at the same time, the middle part of the optical fiber is fixed to the inner wall of the V-groove by applying FA adhesive.

[0010] Preferably, the front cover plate is fixed above the groove by a non-aqueous adhesive; at the same time, the optical fiber tip is fixed to the inner wall of the V-groove by applying non-aqueous adhesive.

[0011] Preferably, the front end of the optical fiber protrudes from the front sidewall of the base.

[0012] Preferably, the upper end face of the base is provided with a recessed platform at the rear end.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This FA full convex fiber polishing device has the advantages of strong operability and low process cost. The polishing yield can reach more than 80% in one pass, and the convex fiber has a beautiful appearance without defects. Attached Figure Description

[0021] 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.

[0022] like Figure 1-5As shown, an FA (fiber optic) full-convex fiber polishing device includes a base 1 with multiple horizontally arranged V-grooves 2 on the base 1; a groove 3 is formed at the front end of the base 1; an optical fiber 4 is placed in each V-groove 2; an upper cover plate 5 is connected to the middle of the base 1 to press down the middle of the multiple optical fibers 4; the upper cover plate 5 is fixed to the middle of the upper end face of the base 1 by applying FA head adhesive; at the same time, the middle of the optical fiber 4 is fixed to the inner wall of the V-groove 2 by applying FA head adhesive.

[0023] Specifically, the front end of the base 1 is connected to the front cover plate 6, which presses down the front ends of multiple optical fibers 4. The front cover plate 6 is fixed above the groove 3 with non-aqueous adhesive; at the same time, the front ends of the optical fibers 4 are fixed to the inner wall of the V-groove 2 with non-aqueous adhesive.

[0024] Specifically, the front end of fiber 4 protrudes from the front side wall of base 1.

[0025] Specifically, a recessed platform 7 is provided at the rear end of the upper surface of the base 1.

[0026] like Figure 1-5 As shown, a groove 3 is opened at the front end of the V-groove 2, dividing the V-groove into 3 parts. The front part is an auxiliary V-groove, which is used to smooth and lift the optical fiber when laying it. The middle groove part is a hollow design, which is to expose the convex fiber part after polishing. The rear V-groove is the functional area, which is the normal FA part.

[0027] When assembling the FA, first use a clamp to fix the optical fiber 4 into the V-groove 3, install the top cover plate 5, leave the distance for the step of the front cover plate 6, and then apply FA head adhesive to fix the V-groove 3, optical fiber 4 and top cover plate 5.

[0028] Then, the front cover plate 6 is fixed to the front end of the V-groove 3 using a non-aqueous adhesive.

[0029] Grind the FA to a certain angle (usually 42.5 degrees). At this time, the non-aqueous adhesive and the front cover plate 6 protect the front fiber from wear and proper grinding.

[0030] Remove the front cover plate 6 and the non-water-soluble adhesive to form the product we want to achieve.

[0031] This FA fully convex fiber polishing device features multiple horizontally arranged V-grooves 2 on a base 1; a groove 3 at the front end of the base 1; an optical fiber 4 placed in each V-groove 2; an upper cover plate 5 connected to the middle of the base 1, pressing down the middle of the multiple optical fibers 4; and a front cover plate 6 connected to the front end of the base 1, pressing down the front end of the multiple optical fibers 4. It has the advantages of strong operability and low process cost, and the polishing yield can reach over 80% in one pass, resulting in a beautiful convex fiber appearance without defects.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
