[0002] In the assembly of passive optical devices fiber arrays in optical communication, optical fibers need to be assembled into V-grooves. The current jig operation method is as follows: put it into the V-groove, use the left hand to push the jig gripper to clamp the V-groove. After loading the optical fiber, the gripper still needs to be manually opened to put the cover plate. The following defects exist:

[0003] 1. It is extremely dependent on personal operation feel, the force is not easy to control, and it is easy to deviate from the center position. Since the gland fixture is stressed in the center, the deviation of the V-groove from the center position makes the gland unable to press the assembled product, easily leading to assembly failure;

[0004] 2. After loading the optical fiber, opening the gripper to put the cover plate is also likely to cause the position of the optical fiber to change and leave the V-groove, affecting the assembly.

[0005] Therefore, the existing jigs have uneven gripping force, inconvenient operation and difficult control, high operation difficulty, the assembled products cannot be maintained, low first-pass yield, high repeatability, difficult efficiency improvement, strong dependence on operation techniques, affecting the assembly yield, high operation difficulty, poor stability and low efficiency.

[0036] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0037] like Figures 1 to 6 As shown, an FA assembly fixture includes a bottom plate 7, a base 6 is arranged on the bottom plate 7, a placement area for accommodating FA is arranged on the base 6, clamping mechanisms for clamping FA are arranged on both sides of the placement area on the base 6, a clamping mechanism for clamping the cover plate of FA is arranged above the placement area on the base 6, and a driving mechanism is also arranged on the base 6. The driving mechanism is transmission-connected with the clamping mechanism and can drive the clamping mechanisms on both sides of the placement area to move closer or farther synchronously to clamp or release FA.

[0038] The FA assembly fixture of the present invention places the FA to be assembled in the placement area, and then drives the clamping mechanism to clamp the V-groove base and the cover plate of the FA through the driving mechanism to achieve the positioning of the V-groove base of the FA, and combines with the clamping mechanism to press the cover plate of the FA downward, so that precise bonding assembly can be achieved after dispensing glue between the V-groove base and the cover plate of the FA, and the clamping mechanism can adjust the clamping position, which greatly improves the assembly efficiency and reduces the assembly failure rate, and the placement area between the clamping mechanisms can adapt to the assembly of FAs of different specifications and sizes, and the matching degree of the product is higher.

[0039] In one or more embodiments of the present invention, the clamping mechanism includes two clamping blocks, a clamping table, and a guide shaft 8. A clamping groove is recessed downward on the base 6 along a direction perpendicular to the V-groove on the FA. The guide shaft 8 is arranged between the inner walls at both ends of the clamping groove. The two clamping blocks and the clamping table are respectively sleeved on the guide shaft 8, and the two clamping blocks are located on both sides of the clamping table. A placement area is formed between the upper surface of the clamping table and the clamping blocks on both sides. The clamping blocks can slide on the guide shaft 8. One end of the clamping block close to the driving mechanism is connected to the driving mechanism, and the driving mechanism can drive the two clamping blocks to move synchronously closer to or away from each other to clamp or loosen the FA. By providing the guide shaft 8 and arranging the clamping blocks on the guide shaft 8, it is convenient for the driving mechanism to drive the two clamping blocks to clamp the V-groove base and the positioned cover plate of the FA to be assembled in the placement area, ensuring that there is no loosening or displacement. At the same time, the clamping table can provide a placement area for the FA to be assembled, playing a supporting role to ensure the smooth completion of the assembly.

[0040] In an embodiment of the present invention, in order to ensure the stability of the movement of the clamping blocks and the firmness of clamping the V-groove base, two guide shafts 8 are arranged in parallel at intervals, so that the clamping blocks move stably under the drive of the driving mechanism.

[0041] As Figure 3 shown, in one or more embodiments of the present invention, the clamping block includes a cover plate clamping block 17 and a base clamping block 18. The cover plate clamping block 17 is arranged on the base clamping block 18, and the cover plate clamping block 17 and the base clamping block 18 are connected by a height adjustment bolt. The height of the cover plate clamping block 17 can be adjusted by the height adjustment bolt. A through hole matching the guide shaft 8 is formed through the base clamping block 18 along a direction perpendicular to the V-groove on the FA. The base clamping block 18 is sleeved on the guide shaft 8, and the driving mechanism drives the base clamping block 18 together with the cover plate clamping block 17 to slide along the guide shaft 8. By providing the cover plate clamping block 17 and the base clamping block 18, when the driving mechanism drives the base clamping block 18 together with the base clamping block 18 to move along the guide shaft 8, the cover plate clamping block 17 and the base clamping block 18 can respectively clamp the V-groove base and the cover plate of the FA to be assembled, ensuring that there is no loosening or displacement of the V-groove base and the cover plate before the assembly is complete.

[0042] Here, three height adjustment bolts are provided. One adjustment bolt drives the cover plate clamping block 17 to move upward, and the other two lock the cover plate clamping block 17 downward, thereby realizing the height adjustment of the cover plate clamping block 17.

[0043] In one or more embodiments of the present invention, the cross-section of the cover clamping block 17 on the side close to the placement area is wedge-shaped. The side walls of the two cover clamping blocks 17 on the side close to the placement area clamp both sides of the cover of the FA respectively. A relief groove for the pressing mechanism to move downward and press the FA is provided on the surface of the cover clamping block 17 on the side close to the placement area. The height of the cover clamping block 17 is adjusted to be equal to the set height of the cover of the FA. By setting the cross-section of the cover clamping block 17 on the side close to the placement area to be wedge-shaped, it can ensure that the cover clamping block 17 is more accurate when clamping the cover. And setting the relief groove can facilitate the downward movement of the clamping mechanism to enter the relief groove, abut against the cover of the FA to be assembled, and press down the cover of the FA to be assembled.

[0044] In one or more embodiments of the present invention, the driving mechanism includes a displacement table pressing plate 9, a slide table handle 15, two displacement tables 10, a driving rod and two driving blocks. A driving groove is provided adjacent to the clamping groove on the base 6. The two displacement tables 10 are correspondingly arranged at both ends of the driving groove. The displacement table pressing plate 9 covers the upper ends of the two displacement tables 10. The driving rod is arranged between the two displacement tables 10 along a direction parallel to the guide shaft 8, and one end of the driving rod extends out of the corresponding displacement table 10. The slide table handle 15 is arranged at the end of the driving rod extending out of the displacement table 10. The two driving blocks are sleeved on the driving rod at intervals and are respectively threadedly connected to the driving rod. One end of the base clamping block 18 away from the clamping groove extends into the driving groove and is respectively connected and fixed to the corresponding driving block. The slide table handle 15 drives the driving rod to rotate, and the driving rod drives the two driving blocks to drive the base clamping block 18 and the corresponding cover clamping block 17 to move closer to or away from each other synchronously to clamp or loosen the FA. By setting the driving rod, by screwing the slide table handle 15, the driving rod can drive the two driving blocks to drive the base clamping block 18 and the corresponding cover clamping block 17 to move closer to or away from each other synchronously to clamp or loosen the FA, which can be adaptively adjusted for different specifications and sizes, and the operation is simple and convenient.

[0045] Here, in order to prevent the driving block from rotating and being displaced relative to the driving rod during movement on the driving rod, in practice, by setting two driving rods and cooperating with the displacement table pressing plate 9, it can ensure that the two driving blocks move smoothly and synchronously on the driving rod.

[0046] In one or more embodiments of the present invention, the driving mechanism further includes a slide table locking screw 16. A locking hole facing the driving rod is provided on the side wall of the driving groove close to the slide table handle 15. The slide table locking screw 16 passes through the displacement table pressing plate 9 and extends into the locking hole. Rotating the slide table locking screw 16 can lock or loosen the driving rod. By providing the slide table locking screw 16, when the driving rod drives the two driving blocks to drive the base clamping block 18 and the corresponding cover clamping block 17 to move closer to each other synchronously to clamp the FA, it can prevent the driving rod from rotating randomly, which may affect the fixation of the V-groove base of the FA by the base clamping block 18 and the corresponding cover clamping block 17 to the cover, further ensuring the assembly accuracy.

[0047] Before assembly, when it is necessary to rotate the driving rod, loosen the slide table locking screw 16 so that the slide table locking screw 16 is separated from the driving rod. During assembly, when the base clamping block 18 and the corresponding cover clamping block 17 clamp the V-groove base and the cover respectively, in order to prevent the driving rod from rotating, tighten the slide table locking screw so that the slide table locking screw 16 abuts against the driving rod. After the assembly is completed, loosen the slide table locking screw 16 again so that the slide table locking screw 16 is separated from the driving rod.

[0048] In one or more embodiments of the present invention, the FA assembly fixture further includes an optical fiber fixing member 11, an optical fiber pressing plate 12, a sponge block 13, and a hand-tightening screw 14. The optical fiber fixing member 11 is provided on the base 6 and is located on both sides of the optical fiber 20. The optical fiber pressing plate 12 is rotatably provided on the base 6 along a direction perpendicular to the optical fiber 20 on the side of the optical fiber fixing member 11 away from the placement area. A protection groove adapted to the sponge block 13 is provided on the lower surface of the optical fiber pressing plate 12. The sponge block 13 is provided in the protection groove. The hand-tightening screw 14 is provided at one end of the optical fiber pressing plate 12, and the hand-tightening screw 14 passes through the optical fiber pressing plate 12 and is movably connected to the upper surface of the base 6. The optical fiber pressing plate 12 can drive the sponge block to rotate to abut against the base 6, and the hand-tightening screw 14 locks the optical fiber pressing plate 12 and the base 6 to press the optical fiber 20 against the surface of the base 6. By providing the optical fiber fixing member 11, the optical fiber pressing plate 12, and the sponge block 13, the optical fiber 20 of the FA can be limited and fixed, and by providing the sponge block 13, while fixing the optical fiber 20 of the FA, the damage to the optical fiber 20 can be reduced, improving the product quality.

[0049] In this application, the displacement table pressing plate 9 is U-shaped, the optical fiber fixing member 11 is located inside the U-shaped opening, and the optical fiber pressing plate 12 is provided on one side of the U-shaped opening.

[0050] In one or more embodiments of the present invention, the pressing mechanism includes an upward-pulling handle 1 with an L-shaped interface, an adjusting portion 2, a pressing block 3, a pressing plate 5, a spring 19, and a guide rod 21. The pressing plate 5 is disposed on the surface of the clamping groove on the base 6 away from the driving mechanism. The upward-pulling handle 1 is disposed on the pressing plate 5, and the guide rod 21 penetrates through the upward-pulling handle 1 and the pressing plate 5. The adjusting portion 2 is disposed at the upper and lower ends of the guide rod 21. The spring 19 is sleeved on the guide rod 21 and is located between the adjusting portion 2 and the upper surface of the upward-pulling handle 1. In the natural state, the spring 19 is in a compressed state. One end of the upward-pulling handle 1 close to the placement area extends downward, and the pressing block 3 is disposed between the two sides of the end of the upward-pulling handle 1 close to the placement area. In the natural state, the spring 19 drives the upward-pulling handle 1 to drive the pressing block 3 to press down the cover plate of the FA. When the upward-pulling handle 1 is lifted upward, the upward-pulling handle 1 drives the pressing block 3 to move upward to separate the pressing block 3 from the cover plate of the FA. By providing the upward-pulling handle 1, the pressing block 3, and the guide rod 21, the pressing block 3 can be moved upward and rotated together by the upward-pulling handle 1 to expose the placement area, facilitating the placement of the V-groove base and the cover plate of the FA to be assembled. The spring 19 can facilitate the automatic reset of the upward-pulling handle 1 after release. The pressure of the spring 19 can be conveniently adjusted through the adjusting portion, thereby adjusting the pulling force for pulling the upward-pulling handle 1, making the operation more convenient.

[0051] Here, the adjusting portion includes a cylindrical fixing portion at the lower end of the guide rod 21 and a rotating portion at the upper end of the guide rod 21. In practice, a pressure adjustment screw is used to adjust the distance between the adjusting portion and the upward-pulling handle 1, thereby adjusting the compression degree of the spring to achieve the adjustment of the pulling force for pulling the upward-pulling handle 1.

[0052] In one or more embodiments of the present invention, the pressing plate 5 is provided with a waist-shaped hole for the upward-pulling handle 1 and the guide rod 21 to pass through. The length direction of the waist-shaped hole is parallel to the V-groove direction of the FA. The guide rod 21 can drive the upward-pulling handle 1 to move along the V-groove direction of the FA. By providing the waist-shaped hole, the guide rod 21 can conveniently drive the upward-pulling handle 1 to move along the V-groove direction of the FA, thereby adjusting the position of the pressing block 3 to be applicable to FAs of different specifications and sizes and achieving precise assembly.

[0053] In an embodiment of the present invention, fixing holes 4 are respectively provided at the four corners of the bottom plate 7 to facilitate fixing the bottom plate 7 to an external carrier.

[0054] The present invention also provides a method for assembling an FA, using the FA assembly fixture as described above, characterized by including the following steps:

[0055] Adjust the initial positions of the pressing mechanism and the clamping mechanism on the FA assembly fixture according to the FA to be assembled, where the gap in the middle of the clamping mechanism is greater than the width of the FA;

[0056] Lift the upper pull handle 1 upward and rotate it by an angle to expose the placement area, and adjust the height adjustment bolt so that the height of the cover plate clamping block 17 is equal to the set height of the cover plate of the FA;

[0057] Place the V-groove base of the FA in the placement area, adjust the slide table handle 15 and drive the two base clamping blocks 18 and the corresponding cover plate clamping blocks 17 to approach each other synchronously via the drive rod to clamp the V-groove base and the cover plate of the FA, tighten the slide table locking screw 16 and ensure that the V-groove base is fixed;

[0058] Rotate and open the optical fiber pressing plate 12, place one end of the optical fiber 20 in the V-groove on the V-groove base of the FA one by one, and pass the other end of the optical fiber 20 through the area between the two optical fiber fixing members 11, and rotate and close the optical fiber pressing plate 12. The optical fiber pressing plate 12 drives the sponge block to rotate and abut against the base 6, and presses the optical fiber 20 against the surface of the base 6;

[0059] Place the cover plate of the FA and adjust its position to be completely aligned with the V-groove base, rotate the upper pull handle 1 above the placement area so that the pressing block 3 presses down on the cover plate of the FA;

[0060] Apply glue at the steps and the end points of the V-groove of the V-groove base of the FA, and bond and fix the V-groove base and the cover plate;

[0061] Lift the upper pull handle 1 upward and rotate it by an angle to expose the placement area, loosen the slide table locking screw 16, adjust the slide table handle 15 and drive the two base clamping blocks 18 and the corresponding cover plate clamping blocks 17 to move away from each other synchronously via the drive rod to loosen the FA;

[0062] Rotate and open the optical fiber pressing plate 12, and take out the assembled FA from the placement area to complete the assembly.

[0063] The FA assembly method of the present invention exposes the placement area by lifting the upper pull handle 1 upward and rotating it by an angle, so that it is more convenient to place the FA to be assembled. By adjusting the slide table handle 15 and driving the two base clamping blocks 18 and the corresponding cover plate clamping blocks 17 to approach each other synchronously via the drive rod to clamp the V-groove base and the cover plate of the FA, precise positioning and fixing of the FA are achieved. By providing the optical fiber fixing members 11, the optical fiber pressing plate 12 and the sponge block 13, the optical fiber 20 of the FA can be limited and fixed, and by providing the sponge block 13, while fixing the optical fiber 20 of the FA, damage to the optical fiber 20 can be reduced and the product quality can be improved.

[0064] It should be noted that for FA assemblies of different specifications and dimensions, before assembly, the upper pull handle 1 can be driven to move along the V-groove direction of the FA by the guide rod 21, so as to adjust the position of the pressing block 3.

[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
