[0002] With the rapid development of communication networks, fiber optic connectors, characterized by their simplicity, reliability, low insertion loss, and low return loss, are primarily used in fiber optic communication systems, data centers, local area networks (LANs), broadcast television networks, and other scenarios requiring high reliability and high-performance optical transmission. Fiber optic connectors connect fiber optic transmission equipment, switches, and optical modules to achieve high-speed, stable fiber optic communication. In building large-scale fiber optic communication networks, fiber optic connectors, due to their standardized interface dimensions and connection methods, are compatible with other fiber optic equipment and connectors, ensuring smooth network operation. Currently, the production of fiber optic connectors is primarily manual, with each connector individually crimped between the tailstock and ferrule.

Detailed Implementation

[0028] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0029] Example 1

[0030] like Figures 1 to 4As shown, the fully automatic fiber optic connector ceramic ferrule crimping and testing device includes a crimping worktable 1. A tailstock vibrating feeding plate 2 and a ferrule vibrating feeding plate 3 are respectively arranged on both sides of the crimping worktable 1. A supporting base 4 is slidably mounted on the crimping worktable 1, and a tailstock tooling plate 5 is slidably mounted on the supporting base 4. The moving direction of the tailstock tooling plate 5 is perpendicular to the moving direction of the supporting base 4. Several tailstock tooling holes 6 are opened on the top surface of the tailstock tooling plate 5, arranged in a rectangular array. A pipeline conveying assembly is provided on the tailstock vibrating feeding plate 2, including a conveying pipeline 7. The conveying pipeline 7 is installed at an angle, with its high end connected to the output end of the tailstock vibrating feeding plate 2, and its low end located at the tailstock tooling plate 2. Within the moving range of plate 5, the ferrule vibrating feeder 3 is also equipped with a pipeline conveying assembly. A ferrule fixture plate 9 is placed on the crimping worktable 1. The ferrule fixture plate 9 has several ferrule through holes 10. The ferrule fixture plate 9 is gripped and conveyed onto the tailstock fixture plate 5 by a robotic arm, ensuring that the several ferrule through holes 10 correspond one-to-one with several tailstock fixture holes 6. A crimping assembly is located above the crimping worktable 1. The crimping assembly includes a crimping plate 11, which has a degree of freedom to move along the height of the crimping worktable 1. The crimping plate 11 is used to crimp the ferrule onto the tailstock. The fiber optic connector includes a tailstock and a ceramic ferrule. The tailstock is crimped to the ceramic ferrule. The tailstock is placed inside the tailstock vibrating feeder 2, and the tailstock is crimped by the tailstock vibrating feeder 2. The tailstock is fed in a neat and orderly manner, falling into the conveying pipe 7 of the tailstock vibrating feeder 2. The inner diameter of the conveying pipe 7 matches the diameter of the tailstock, allowing the tailstock to be conveyed within the pipe. The supporting chassis 4 drives the tailstock tooling plate 5 to move horizontally. The tailstock tooling plate 5 can move horizontally, and its direction of movement is perpendicular to that of the supporting chassis 4, giving it two degrees of vertical freedom of movement on the horizontal plane. This allows the multiple tailstock tooling holes 6 on the tooling plate 5 to move sequentially to directly below the output port of the conveying pipe 7. Under the action of the tailstock vibrating feeder 2, the conveying pipe 7 vibrates slightly, allowing the tailstock to move smoothly within it. The tailstock then falls from the conveying pipe 7 into the tailstock tooling plate. The tailstock is sequentially fed into multiple tailstock tooling holes 6. Then, the tailstock tooling plate 5 is reset, and the ferrule tooling plate 9 is placed on the tailstock tooling plate 5 by the robot arm, so that the tailstock tooling holes 6 are coaxially aligned with the ferrule through holes 10. Then, the tailstock tooling plate 5 moves to the feeding position of the ferrule vibrating feeding plate 3. The ceramic ferrule is placed in the ferrule vibrating feeding plate 3, and the ferrule is regularly conveyed by the ferrule vibrating feeding plate 3, so that the ferrule falls into the conveying pipe 7 of the ferrule vibrating feeding plate 3. With the movement of the tailstock tooling plate 5, the ferrule is sequentially fed into multiple ferrule through holes 10. The axial dimension of the ferrule through hole 10 is designed according to the size of the ferrule. The ferrule enters the ferrule through hole 10, and the top of the ferrule is above the top surface of the ferrule tooling plate 9.The distance between the top of the ferrule and the top surface of the ferrule fixture plate 9 is equal to the crimping depth of the ferrule. Then, the crimping plate 11 moves downward, pressing the ferrule downward. When the crimping plate 11 contacts the ferrule fixture plate 9, it indicates that the tail shank and ferrule have completed the crimping operation. Then, the crimping plate 11 moves upward to reset, and the robotic arm removes the ferrule fixture plate 9 and places it back in its original position. The robotic arm then sequentially unloads the crimped fiber optic connectors. After unloading, the above crimping operation is repeated, realizing the automated and mass production of fiber optic connectors. It can crimp multiple fiber optic connectors simultaneously, improving the crimping efficiency of fiber optic connectors. Furthermore, the automated production of fiber optic connectors reduces labor costs and the defect rate.

[0031] Example 2

[0032] Based on Example 1, such as Figure 1 and Figure 4As shown, the crimping assembly further comprises a crimping frame 29, on which a lifting strut 30 is arranged. The top of the lifting strut 30 is rotatably provided with a switching crossbeam 31. The bottom of one end of the switching crossbeam 31 is connected to the crimping plate 11, and the bottom of the other end of the switching crossbeam 31 is connected to a detection plate 32. A plurality of infrared sensors 33 are mounted on the bottom surface of the detection plate 32, and the plurality of infrared sensors 33 are in one-to-one correspondence with the plurality of tail shank tooling holes 6. A cylinder 34 is vertically mounted on the crimping frame 29, and the telescopic shaft of the cylinder 34 is connected to the lifting strut 30. The top of the lifting strut 30 is rotatably provided with a switching main shaft 35, which is fixedly connected to the switching crossbeam 31. A first gear 36 is sleeved on the switching main shaft 35, and a switching motor 37 is mounted on the lifting strut 30. The output shaft of the switching motor 37 is connected to a second gear 38, which meshes with the first gear 36. The expansion and contraction of the cylinder 34 drives the lifting strut 30 to move up and down, and the lifting strut 30 drives the switching crossbeam 31 to move up and down. During crimping, the switching crossbeam 31 drives the crimping plate 11 to move downward, and the ferrule is squeezed by the crimping plate 11 to complete the crimping operation. After the crimping is completed and the ferrule tooling plate 9 is removed, quality inspection needs to be carried out first before the optical connector is unloaded. The specific operation is as follows: the switching motor 37 drives the switching main shaft 35 to rotate through the meshing of the first gear 36 and the second gear 38, and the switching main shaft 35 drives the switching crossbeam 31 to rotate, so that the detection plate 32 is aligned with the tail shank tooling plate 5. The top surface height of the ferrule is detected by the infrared sensor 33, so as to judge the crimping depth of the ferrule, thereby detecting whether the crimping of the ferrule is qualified. According to the feedback of the infrared sensor 33, the optical connectors are sorted and unloaded into qualified and unqualified ones. An unqualified box and a qualified box are arranged on the side of the crimping workbench 1. The unloaded optical connectors that pass the inspection are placed in the qualified box, and the unloaded optical connectors that fail the inspection are placed in the unqualified box. There are two types of unqualified conditions: exceeding the standard length and being shorter than the standard length; therefore, the unqualified box is divided into two spaces, one for placing optical connectors exceeding the standard length, and the other for those shorter than the standard length. For the ones shorter than the standard size: use a special tool to separate the ceramic ferrule and the tail shank, and perform crimping again. For the ones exceeding the standard size: start the rework process system to analyze the cause of the excess.

[0033] Third Embodiment

[0034] On the basis of the second embodiment, as shown in Figures 1 to 3As shown, the conveying pipe 7 includes an input pipe 12, a conveying hose 13, and an output pipe 14. The conveying hose 13 is inclined, and its high end is connected to the input pipe 12. The input pipe 12 is vertically arranged directly below the output end of the tail vibrating feed pan 2. The output pipe 14 is vertically connected to the bottom end of the conveying hose 13. A tapered guide pipe 15 is fixed to the top of the input pipe 12. A guide hole 16 is opened through the tapered guide pipe 15 along its own axial direction. The diameter of the guide hole 16 gradually decreases towards the conveying hose 13. The top of the tapered guide pipe 15... The section has a large capacity, allowing the tailstock output from the tailstock vibrating feeder 2 to fall smoothly into the tapered guide tube 15. Under the action of the guide hole 16, the tailstock falls into the input pipe 12, and then enters the output pipe 14 through the conveying hose 13. The output pipe 14 is set vertically, so that the output pipe 14 can coaxially correspond to the tailstock tooling hole 6, allowing the tailstock to fall accurately into the tailstock tooling hole 6, thus achieving precise feeding of the tailstock. Similarly, the conveying pipe on the core vibrating feeder 3 has the same structure as the conveying pipe on the tailstock vibrating feeder 2, thus achieving precise feeding of the core.

[0035] Example 4

[0036] Since it is necessary to sequentially feed multiple tail shanks into multiple tail shank tooling holes 6 and multiple inserts into multiple insert through holes 10, in order to avoid sequentially conveying multiple tail shanks or inserts, based on embodiment three, such as Figures 1 to 4As shown, the pipeline conveying assembly also includes a limiting mounting bracket 17, a front baffle 18, and a rear baffle 19. The rear baffle 19 is vertically positioned at the output end of the tail shank vibrating feed plate 2, and the front baffle 18 is vertically positioned above the tail shank vibrating feed plate 2. The output end of the tail shank vibrating feed plate 2 is located between the front baffle 18 and the rear baffle 19. The front baffle 18 and the rear baffle 19 are staggered in the vertical direction, and both the front baffle 18 and the rear baffle 19 have a degree of freedom to move in the vertical direction. Two drive plates 20 are slidably mounted on the limiting mounting bracket 17, and racks 21 are connected to the opposite end faces of the two drive plates 20. A gear 22 is arranged between each rack 21. The gear 22 is rotatably connected to the limiting mounting bracket 17 via the main shaft 23. Both racks 21 mesh with the gear 22. A motor 24 is mounted on the limiting mounting bracket 17. The output shaft of the motor 24 is connected to the main shaft 23. Two drive plates 20 are connected to the front baffle 18 and the rear baffle 19 respectively via a special-shaped connecting rod 25. When the tail shank is not being fed, the rear baffle 19 moves downward to block the output end of the tail shank vibrating feeding plate 2, preventing the tail shank from entering the conveying pipe 7. At this time, the front baffle 18 is located between the last tail shank and the next tail shank, and is above the tail shank. When the tailstock is being fed, the motor 24 drives the main shaft 23 to rotate, the main shaft 23 drives the gear 22 to rotate, and the gear 22 drives the two racks 21 to move linearly. Since the two racks 21 are arranged opposite to each other, their directions of movement are opposite. The two racks 21 drive the front baffle 18 and the rear baffle 19 to move respectively through the irregular connecting rod 25. This causes the rear baffle 19 to move upward and disengage from the tailstock, allowing the front baffle 18 to insert between the end tailstock and the next tailstock. The front baffle 18 inserts between the end tailstock and the next tailstock first, and then the rear baffle 19 disengages from the end tailstock. The front baffle 18 blocks the next tailstock and its... After the tailstock is no longer blocked by the rear baffle 19, it falls into the conveying pipe 7. Then, the motor 24 reverses, so that the rear baffle 19 continues to block the output end of the tailstock vibrating feed plate 2. The front baffle 18 moves upward and disengages from the tailstock. At this time, the tailstock moves and contacts the rear baffle 19 to complete the limit. The tailstock in the previous position becomes the end tailstock. When the tailstock tooling plate 5 moves the next tailstock tooling hole 6 to the feeding position, the rear baffle 19 and the front baffle 18 repeat the above actions, so that one tailstock can be accurately fed each time. Similarly, the insert vibrating feed plate 3 also feeds one insert at a time in this way.

[0037] Example 5

[0038] Based on Example 4, such as Figures 1 to 3As shown, a transverse linear drive module 26 is mounted on the top surface of the pressing workbench 1. A support chassis 4 is mounted on the slide of the transverse linear drive module 26. A longitudinal linear drive module 8 is mounted on the top surface of the support chassis 4. A tail shank tooling plate 5 is mounted on the slide of the longitudinal linear drive module 8. The transverse linear drive module 26 drives the support chassis 4 to move, and the longitudinal linear drive module 8 drives the tail shank tooling plate 5 to move, giving the tail shank tooling plate 5 two degrees of freedom of vertical movement in the horizontal direction. The top surface of the tail shank tooling plate 5 is open. A tapered positioning hole 27 is provided, and a positioning cone 28 is fixed on the bottom surface of the insert tooling plate 9. When the positioning cone 28 is fitted into the tapered positioning hole 27, a number of insert through holes 10 and a number of tail shank tooling holes 6 are coaxially aligned. When the robot arm places the insert tooling plate 9 on the tail shank tooling plate 5, the positioning cone 28 is inserted into the tapered positioning hole 27, thereby completing the positioning and matching of the insert tooling plate 9 and the tail shank tooling plate 5. At the same time, when the tail shank tooling plate 5 moves, the position between the tail shank tooling plate 5 and the insert tooling plate 9 will not shift.

[0039] The fully automated method for automatic crimping and testing of ceramic ferrules in fiber optic connectors, utilizing the aforementioned crimping and testing device, includes the following steps:

[0040] S1. The tail shanks are neatly arranged by the tail shank vibrating feeding plate 2 to be in the state of waiting to be fed. Then, the tail shanks are transported to the tail shank tooling plate by the pipeline conveying assembly on the tail shank vibrating feeding plate 2. One tail shank is placed in each tail shank tooling plate 5.

[0041] S2. The robot arm places the ferrule fixture plate 9 on the tail shank fixture plate 5, so that the tail shank fixture hole 6 corresponds to the ferrule through hole 10.

[0042] S3. The core vibrating feeding plate 3 arranges the cores neatly so that they are ready to be fed. Then, the cores are transported to the core tooling plate 9 through the pipeline conveying assembly on the core vibrating feeding plate 3 so that the cores are located in the core through hole 10.

[0043] S4. The pressing plate 11 moves downward to press all the inserts, thereby pressing multiple inserts into the corresponding tail shank at the same time.

[0044] S5. The switching beam 31 is rotated to put the detection plate 32 in the working position. The infrared sensor 33 detects the crimping quality of each ceramic ferrule. The robot arm puts qualified products into the qualified area and unqualified products into the unqualified area.

[0045] S6. Repeat the above operations S1-S5 to complete the mass production of ceramic ferrules.

8. A fully automated method for automatic crimping detection of ceramic ferrules in fiber optic connectors, utilizing the crimping detection device as described in claim 7, characterized in that... Includes the following steps: S1. The tail shank is neatly arranged by the tail shank vibrating feeding plate (2) to be in the state of waiting to be fed. Then the tail shank is transported to the tail shank tooling plate by the pipeline conveying assembly on the tail shank vibrating feeding plate (2). One tail shank is placed in each of the tail shank tooling plates (5). S2. The robot arm places the ferrule tooling plate (9) on the tail shank tooling plate (5) so that the tail shank tooling hole (6) corresponds to the ferrule through hole (10). S3. The core vibrating feeding plate (3) arranges the cores neatly so that they are ready to be fed. Then, the cores are transported to the core tooling plate (9) through the pipeline conveying assembly on the core vibrating feeding plate (3) so that the cores are located in the core through hole (10). S4. The pressing plate (11) moves downward to press all the inserts, thereby pressing multiple inserts into the corresponding tail shank at the same time. S5. The switching beam (31) rotates to put the detection plate (32) in the working position. The crimping quality of each ceramic ferrule is detected by the infrared sensor (33). The qualified products are put into the qualified area and the unqualified products are put into the unqualified area by the robot arm. S6. Repeat the above operations S1-S5 to complete the mass production of ceramic ferrules.
