Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber sensitive ring production and manufacturing, in particular to an adapter tool for automatic dispensing and bonding of optical fiber rings. Background Technique

[0002] In the field of precision manufacturing of fiber optic gyroscopes, as a core sensitive component, the bonding quality of the fiber optic ring during the production process plays a crucial role in the performance of the final product. Currently, the bonding process between the fiber optic ring and the metal base mostly adopts manual operation, and this method has significant deficiencies. Specifically, it is difficult to uniformly control the amount of glue during the manual bonding process, resulting in bonding parallelism and angular deviation, which in turn affects the accuracy and stability of the fiber optic gyroscope. In addition, there are also risks such as glue sticking in non-bonding areas, damage to the pigtail and body of the fiber optic ring during manual operation, which not only reduces the product quality but also increases the production cost and scrap rate.

[0003] In view of the above defects of manual bonding, the industry has begun to explore an automatic transformation plan for bonding the fiber optic ring and the metal base. However, during the automatic bonding process, especially when the bonding surface of the fiber optic ring faces upward and the bonding surface of the metal base faces downward and is integrally inverted, the fixation of the pigtail becomes a major problem. During the flipping and clamping process of the robotic arm, it is difficult to ensure the state of the pigtail, increasing the risk of pigtail damage and posing extremely high requirements for the control accuracy and situation awareness ability of the automatic equipment. Content of the Utility Model

[0004] In view of this, in view of the deficiencies existing in the prior art, the main purpose of the present utility model is to provide an adapter tool for automatic dispensing and bonding of fiber optic rings, which solves the technical problems of unstable bonding quality, easy damage to the pigtail, increased production cost and scrap rate, as well as low production efficiency and difficulty in meeting the automatic requirements during the bonding process between the fiber optic ring and the metal base.

[0005] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0006] An adapter tool for automatic dispensing and bonding of fiber optic rings of the present utility model includes:

[0007] A tooling main body, on which an installation ring column protrudes;

[0008] A fiber optic ring component, which is placed on the installation ring column. A pigtail ring groove is opened on the outer peripheral side of the installation ring column of the tooling main body. Between the pigtail ring groove and the installation ring column, there are also multiple positioning columns. The positioning columns are installed on the tooling main body and are arranged at equal intervals along the outer peripheral side of the fiber optic ring component. An avoidance arc groove is also opened on the tooling main body, which is arranged between two adjacent positioning columns, and the center of the arc of the avoidance arc groove coincides with the center of the ring of the installation ring column;

[0009] The fiber climbing steps are symmetrically arranged on any two adjacent avoidance arc grooves and are installed on the outer side wall of the installation ring column. The fiber climbing steps are spirally ascending. One end of the fiber optic ring member close to the tooling main body is convexly provided with an out-fiber step, and the out-fiber step is located between the two fiber climbing steps. An out-fiber avoidance groove corresponding to the out-fiber step is opened on the installation ring column. Avoidance notches corresponding to the fiber climbing steps one by one are opened on one side of the pigtail ring groove close to the fiber optic ring member.

[0010] The mounting seat is provided with a fitting ring groove corresponding to the fiber optic ring member. The mounting seat is fitted and installed on the fiber optic ring member and is bonded to one end of the fiber optic ring member away from the tooling main body.

[0011] As a preferred solution, it further includes an extension column. A jack is opened at one end of the positioning column away from the tooling main body, and the extension column is detachably installed on the jack.

[0012] As a preferred solution, one end of the installation ring column close to the mounting seat is provided with a placement surface, and a positioning convex ring is convexly provided on the placement surface.

The depth of the out-fiber avoidance groove is greater than the height of the out-fiber step, and the length of the out-fiber avoidance groove is greater than the length of the out-fiber step. The out-fiber avoidance groove and the out-fiber step together form an avoidance through cavity, and the avoidance through cavity is in an inverted "U" shape and sequentially penetrates through the installation ring column and the positioning convex ring.

[0013] As a preferred solution, a guide inclined surface is further opened at one end of the positioning convex ring away from the placement surface. The fiber optic ring member is in clearance fit with the positioning convex ring, and the outer diameter of the placement surface is 2-3 mm smaller than the outer diameter of the fiber optic ring member.

[0014] As a preferred solution, one end of the fiber optic ring member away from the installation ring column is provided with a first bonding surface, and the bottom of the fitting ring groove is provided with a second bonding surface that cooperates with the first bonding surface.

[0015] As a preferred solution, the fiber climbing steps are located below the out-fiber avoidance groove. The vertical height distance from the out-fiber avoidance groove to the starting end of the fiber climbing steps is 1-2 mm, and the terminating end of the fiber climbing steps is lower than the bottom of the pigtail ring groove.

[0016] As a preferred solution, the avoidance notch is in a 45° arc shape, and the diameter of the inscribed circle formed by multiple positioning columns is greater than the outer diameter of the mounting seat.

[0017] As a preferred solution, the pigtail loop groove is used to place the fiber optic pigtail, and the fiber optic pigtail is fixed to the tooling main body by tape.

[0018] As a preferred solution, the mounting seat is annular, the center of the ring of the mounting seat coincides with the center of the arc of the avoidance arc groove, and a stepped ring block is further convexly provided on the inner ring side of the mounting seat.

At the same time, the tight adhesion between the mounting seat and the fiber optic ring ensures the bonding effect, improves the product quality, effectively reduces the scrap rate and production cost, and meets the automatic and high-precision bonding requirements in the field of fiber optic gyroscope manufacturing.

[0034] Please refer to Figures 1 to 4 , the embodiment of the present utility model provides an adaptation tooling for automatic dispensing and bonding of optical fiber rings, including:

[0035] The tooling main body 10 provides functions of bearing, positioning and protecting the optical fiber tail fiber during the bonding of the optical fiber ring part 20. An installation ring column 11 is convexly provided on the tooling main body 10 for positioning and supporting the optical fiber ring part 20.

[0036] The optical fiber ring part 20 is placed on the installation ring column 11 to achieve precise positioning. The tooling main body 10 is provided with a tail fiber ring groove 12 along the outer peripheral side of the installation ring column 11 for the arrangement and fixation of the optical fiber tail fiber. A plurality of positioning columns 13 are also provided between the tail fiber ring groove 12 and the installation ring column 11. The positioning columns 13 are installed on the tooling main body 10 and are arranged at equal intervals along the outer peripheral side of the optical fiber ring part 20 to ensure the stability and accuracy of the optical fiber ring part 20. An avoidance arc groove 14 is also provided on the tooling main body 10. The avoidance arc groove 14 is arranged between two adjacent positioning columns 13, and the center of the arc of the avoidance arc groove 14 coincides with the center of the ring of the installation ring column 11 to ensure the symmetry of the structure.

[0037] The fiber climbing steps 30 are symmetrically arranged on any two adjacent avoidance arc grooves 14 and are installed on the outer side wall of the installation ring column 11. The fiber climbing steps 30 are in a spiral ascending shape, optimizing the routing path of the fiber optic pigtail and facilitating the spiral climbing of the fiber optic pigtail. One end of the fiber optic ring member 20 close to the tooling main body 10 is convexly provided with a fiber outlet step 21, which serves as the outlet of the fiber optic pigtail. The fiber outlet step 21 is located between the two fiber climbing steps 30, facilitating the leading out of the fiber optic pigtail. An optical fiber outlet avoidance groove 15 corresponding to the fiber outlet step 21 is opened on the installation ring column 11 to ensure the smooth leading out of the fiber optic pigtail. Avoidance notches 16 corresponding to the fiber climbing steps 30 are opened on one side of the pigtail ring groove 12 close to the fiber optic ring member 20 to avoid interference and obstruction, ensuring that the fiber optic pigtails on both sides can fall into the pigtail ring groove 12 in a relatively natural state, so that the work can be carried out continuously and smoothly.

[0038] The mounting seat 40 is a fixing and bonding component for the fiber optic ring member 20. A fitting ring groove 41 corresponding to the fiber optic ring member 20 is opened thereon to ensure the accuracy and stability of the installation. The mounting seat 40 is fitted and installed on the fiber optic ring member 20 and is bonded to one end of the fiber optic ring member 20 away from the tooling main body 10 to achieve a firm connection and ensure the stability and reliability of the overall structure.

[0039] In this embodiment, an extension column 50 is further included. The design of the extension column 50 enhances the flexibility and adaptability of the tooling main body 10. A jack 131 is opened at one end of the positioning column 13 away from the tooling main body 10. The jack 131 serves as the installation interface for the extension column 50 to ensure the stability and accuracy of the connection. The extension column 50 is detachably installed on the jack 131, facilitating the replacement of the extension column 50 with different sizes according to actual needs to adjust the extended size of the positioning column 13, further optimizing the positioning and supporting effects of the fiber optic ring member 20. At the same time, the detachable design is also convenient for maintenance and replacement, improving the practicality and service life of the tooling main body 10.

[0040] One end of the mounting ring column 11 close to the mounting seat 40 is provided with a placement surface 111, which provides a stable support foundation for the optical fiber ring member 20, ensuring the accuracy of the installation process. A positioning convex ring 112 is protruded on the placement surface 111. This design effectively restricts the radial movement of the optical fiber ring member and enhances the stability of the installation. The optical fiber ring member 20 is sleeved on the positioning convex ring 112 and placed on the placement surface 111 to ensure good positioning of the optical fiber ring member 20 in both the axial and radial directions. The depth of the fiber outlet avoidance groove 15 is greater than the height of the fiber outlet step 21 to ensure that the fiber outlet process is not blocked. The length of the fiber outlet avoidance groove 15 is greater than the length of the fiber outlet step 21, providing sufficient bending space for the optical fiber pigtail and reducing the stress it receives during the bending process. The fiber outlet avoidance groove 15 and the fiber outlet step 21 together form an avoidance cavity 60. The avoidance cavity 60 is in a "concave" shape and sequentially penetrates through the mounting ring column 11 and the positioning convex ring 112. This design not only provides a continuous and unobstructed channel for the optical fiber pigtail but also enhances the protection of the optical fiber pigtail during the bending and installation processes.

[0041] One end of the positioning convex ring 112 away from the placement surface 111 is also provided with a guiding inclined surface, which facilitates the quick installation and positioning of the optical fiber ring member 20, improving the installation efficiency. The optical fiber ring member 20 is in clearance fit with the positioning convex ring 112, which not only ensures the stability of the optical fiber ring member 20 but also avoids damage to the optical fiber ring member 20 caused by over-tight fit. The outer diameter of the placement surface 111 is 2-3 mm smaller than the outer diameter of the optical fiber ring member 20, providing sufficient operating space for the installation and adjustment of the optical fiber ring member 20.

[0042] Furthermore, one end of the optical fiber ring member 20 away from the mounting ring column 11 is provided with a first bonding surface 22, and the bottom of the fitting ring groove 41 is provided with a second bonding surface 411 that cooperates with the first bonding surface 22. This design enhances the connection strength between the optical fiber ring member 20 and the fitting ring groove 41, ensures the stable installation of the optical fiber ring member 20, and improves the overall stability and durability.

[0043] The fiber climbing step 30 is located below the fiber outlet avoidance groove 15. This layout provides a reasonable path for the climbing of the optical fiber pigtail, avoiding unnecessary bending and stress on the optical fiber pigtail during the climbing process. The vertical height distance from the fiber outlet avoidance groove 15 to the starting end of the fiber climbing step 30 is 1-2 mm, avoiding excessive bending of the optical fiber pigtail due to too large a height difference. The terminating end of the fiber climbing step 30 is lower than the bottom of the pigtail ring groove 12, ensuring a smooth transition of the optical fiber pigtail before climbing into the pigtail ring groove 12, reducing the friction and damage of the optical fiber pigtail in the pigtail ring groove 12, and improving the transmission efficiency and stability of the optical fiber pigtail.

[0044] Furthermore, the avoidance notch 16 is in a 45° arc shape, which optimizes the bending path and reduces the stress concentration during the bending of the fiber optic pigtail. The diameter of the inscribed circle formed by multiple positioning posts 13 is larger than the outer diameter of the mounting base 40, ensuring that the mounting base 40 will not be interfered by the positioning posts 13 during installation, and improving the convenience and accuracy of installation.

[0045] The pigtail ring groove 12 is used to place the fiber optic pigtail, effectively managing the layout of the fiber optic pigtail and avoiding the chaos of the fiber optic pigtail. The fiber optic pigtail is fixed to the tooling main body 10 by tape. Such a fixing method is simple and practical, ensuring the stability of the fiber optic pigtail during use, effectively restricting the fiber optic pigtail within the area without sliding or falling, and avoiding the risk of damaging the fiber optic pigtail in operations such as reverse buckling and robotic arm clamping.

[0046] The mounting base 40 is annular, and the center of the ring of the mounting base 40 coincides with the center of the arc of the avoidance arc groove 14, ensuring that the bending path of the fiber optic pigtail in the avoidance arc groove 14 matches the central position of the mounting base 40, improving the uniformity and consistency of the bending of the fiber optic pigtail. A stepped ring block 42 is also convexly provided on the inner ring side of the mounting base 40, facilitating additional connection or fixation and enhancing the structural stability of the mounting base 40.

[0047] It should also be noted that the overall tooling presents an annular structure. Non-bonding key structures such as the pigtail groove and the positioning posts 13 adopt a generalized size design, which is easy to adapt to the vision recognition system and the mechanical clamping system, realizing efficient and accurate recognition, positioning, and clamping. In addition, its design also fully considers the smoothness of the automation process, thereby improving production efficiency and reducing the need for human intervention. When the automated production capacity is insufficient to meet the production needs, this tooling can still assist manual production. Its positioning posts 13 can be used in combination with detachable extension posts 50 for positioning during manual bonding.

[0048] Specific working process:

[0049] During the bonding operation, an operator can coil the fiber optic pigtails on both sides of the fiber optic ring part 20 into circles with a diameter equivalent to that of the pigtail ring groove 12, place the fiber optic ring part 20 on the placement surface 111, let the fiber optic pigtails on both sides naturally fall into the pigtail ring groove 12 along the fiber climbing step 30, and fix them with tape. Then, the first bonding surface 22 of the fiber optic ring part 20 is brushed with glue by an automated device or an operator. After the glue brushing is completed, the automated device clamps the mounting base 40, makes the second bonding surface 411 face downwards, and lowers it parallel to the positioning posts 13 until the second bonding surface 411 is closely attached to the first bonding surface 22 until the mounting base 40 cannot be further pressed down. Then, the entire tooling is flipped to complete the bonding process.

[0050] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the principles of the present utility model shall fall within the protection scope of the present utility model.
