Description

Technical Field

[0001] This invention relates to the field of optical fiber processing technology, specifically to a high-stability optical module optical fiber coupling precision positioning mechanism. Background Technology

[0002] Optical modules are among the most important components in modern communications. During operation, the transmitting end converts electrical signals into optical signals, which are then transmitted through optical fibers. The receiving end then converts the optical signals back into electrical signals. The fabrication of the optical fiber in an optical module involves assembling related ceramic ferrules, metal tail shanks, etc., and then connecting the ceramic ferrules to the processed optical fiber end caps.

[0003] During processing and assembly, the assembly of ceramic ferrules and metal tailstocks, as well as the connection assembly of ceramic ferrules and optical fibers, are usually performed on two separate devices. For example, the installation fixture for ceramic ferrule optical fiber connectors with patent publication number CN202443148U is used for crimping and assembling ferrules and tailstocks; the optical fiber assembly mechanism with guide positioning blocks with patent publication number CN110989095B; and the device for manufacturing hollow optical fiber connectors with patent publication number CN221507194U are used for connecting and assembling ferrules and optical fibers.

[0004] Therefore, the above-mentioned equipment can only process ceramic ferrules individually. After each processing, the ceramic ferrule needs to be removed from its original position, transferred from one device to another, and repositioned for subsequent processing. The ceramic ferrule needs to be repeatedly disassembled and repositioned, which is troublesome to operate and transfer, and affects the continuity of processing.

[0005] Based on this, the present invention designs a highly stable optical module fiber coupling precision positioning mechanism to solve the above problems. Summary of the Invention

[0064] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0065] Example 1

[0066] Please refer to the accompanying drawings. This invention provides a technical solution:

[0067] A high-stability optical module fiber coupling precision positioning mechanism includes a base frame 100 and a rotating loading assembly 200 and a rotating processing assembly 400 located on the top two sides of the base frame 100, respectively.

[0068] The rotating processing assembly 400 is provided with a feeding station A, a clamping station B, a core installation station C, a flipping station D, a glue injection station E, and a fiber optic connection station F in sequence and evenly along the circumferential direction. The rotating processing assembly 400 is also provided with six flipping tailstock positioning assemblies 500.

[0069] Multiple insert positioning components 300 are evenly installed on the rotating feeding component 200 along the circumferential direction. The height of the insert positioning component 300 is greater than the height of the flip-type tailstock positioning component 500, and one of the insert positioning components 300 is located at the insert installation station C and above the corresponding flip-type tailstock positioning component 500.

[0070] The top of the rotating processing assembly 400 is provided with a fixing frame 404 above the clamping station B, the insert installation station C, and the glue injection station E. An adjustment assembly 600, a material picking assembly 700, and a glue injection assembly are provided on the corresponding fixing frame 404 in sequence. The bottom of the rotating processing assembly 400 is provided with a flipping drive assembly 800 at the flipping station D.

[0071] The flip-type tailstock positioning assembly 500 has limiting structures on both sides inside, and the flip drive assembly 800 has a corresponding limiting cancellation structure inside.

[0072] When coupling and assembling structures such as optical fibers and ceramic ferrules, the ferrule section 1002 is fed and positioned by rotating the feeding assembly 200 with multiple ferrule positioning assemblies 300. The position is switched by rotating the feeding assembly 200 along the circumferential direction, thereby realizing intermittent feeding of the ferrule section 1002.

[0073] At the loading station A, the flip-type tailstock positioning component 500 is loaded onto the corresponding position on the rotating processing component 400, so that multiple tailstock parts 1001 are located in the component. The rotating processing component 400 is rotated intermittently and its position is switched in sequence. Thus, starting from the loading station A, it passes through the clamping station B, the ferrule installation station C, the flip station D, the glue injection station E, and the optical fiber connection station F in sequence.

[0074] At clamping station B, the internal structure of the flip-type tail shank positioning component 500 is adjusted by adjusting component 600 to clamp and position the tail shank part 1001 after loading. At insert installation station C, multiple insert parts 1002 on insert positioning component 300 are clamped and picked up by material taking component 700. After insert positioning component 300 and material taking component 700 are misaligned, material taking component 700 drives insert part 1002 to move down. Through pressure, insert part 1002 is inserted into tail shank part 1001, completing the crimping of insert part 1002 and tail shank part 1001.

[0075] After the ferrule is installed, the tailstock portion 1001 moves to the flipping station D. The limiting structure in the flipping drive assembly 800 moves the limiting structure in the flipping tailstock positioning assembly 500 and removes the limiting on the flipping structure inside the flipping tailstock positioning assembly 500. As a result, the flipping drive assembly 800 causes the flipping tailstock positioning assembly 500 to flip the tailstock portion 1001 and the ferrule portion 1002, so that the tailstock portion 1001 is above the ferrule portion 1002 and the insertion channel 1005 of the tailstock portion 1001 faces upward.

[0076] At the glue injection station E, the glue is injected into the insertion channels 1005 in the multiple tail sections 1001 through the glue injection assembly. Then, when it moves to the optical fiber connection station F, the treated optical fiber end can be inserted into the tail section 1001 and cured and connected by glue, etc., to realize the component connection operation in optical fiber coupling.

[0077] This invention enables the rotational feeding and positioning of the ferrule portion 1002 and the tailstock portion 1001, making feeding faster and more convenient. Furthermore, through the cooperation of the flip-type tailstock positioning assembly 500, the ferrule positioning assembly 300, and the material handling assembly 700, the crimping assembly of the ferrule portion 1002 and the tailstock portion 1001 is achieved. By setting multiple workstations, this invention can realize the feeding, clamping, positioning, crimping, flipping, gluing, and fiber optic connection of the tailstock portion 1001 during intermittent rotation and position switching, resulting in a more compact connection during processing, improved processing efficiency, and precise positioning and connection of the ferrule portion 1002, the tailstock portion 1001, and the optical fiber.

[0078] Each time the present invention is fed, it can perform feeding and positioning operations on multiple insert parts 1002 and tail shank parts 1001, thereby increasing the number of insert parts 1002 and tail shank parts 1001 in each processing and improving processing efficiency.

[0079] The flip-type tailstock positioning assembly 500 includes a rectangular frame 501 mounted on the rotating processing assembly 400. The rectangular frame 501 has a rectangular flip frame 503 inside. The flip frame 503 has flip gears 502 fixed at both ends. The center of the flip gears 502 is rotatably connected to the middle of the inner end of the rectangular frame 501. The two side walls of the rectangular frame 501 are provided with limiting structures, and the limiting structures contact the bottom sides of the flip frame 503.

[0080] The bottom of the flip gear 502 is engaged with a horizontal flip rack 509. The outer ends of the two flip racks 509 extend out of the rectangular frame 501 and are fixed with a movable plate 510. The other end of the flip rack 509 is connected to the inner side wall of the rectangular frame 501 through a spring, and a shaft hole is provided at the center of the end. A guide shaft 513 is slidably connected through the shaft hole. One end of the guide shaft 513 is fixed to the side wall of the rectangular frame 501.

[0081] Two clamping seats 504 are symmetrically arranged in the flip frame 503. Multiple V-shaped grooves are evenly arranged on the opposite side of the clamping seat 504, and the other side is connected to the side wall of the flip frame 503 through an adjustment structure. Sliding blocks 514 are fixed at both ends of the clamping seat 504. A sliding groove is provided on the inner end of the flip frame 503. The sliding block 514 is slidably connected in the sliding groove and is connected to the end of the sliding groove through a spring.

[0082] The adjustment structure includes an adjustment screw 505 rotatably connected to the inner wall of the flip frame 503. The two sides of the adjustment screw 505 have opposite thread directions and an adjustment gear 506 is fixed in the middle. Adjustment blocks 507 are threadedly connected to the two sides of the adjustment screw 505 respectively. An adjustment wheel 508 is rotatably connected to one end of the adjustment block 507 near the clamping seat 504. The side wall of the clamping seat 504 is provided with two adjustment grooves. The near ends of the two adjustment grooves are provided with symmetrical inclined surfaces, and the adjustment wheel 508 is located in the corresponding adjustment groove and contacts the wall surface of the adjustment groove.

[0083] The limiting structure includes vertical limiting support plates 511 symmetrically located on both sides of the outside of the flip frame 503. A horizontal boss is fixed on the lower inner side of the limiting support plate 511, and the boss contacts the bottom ends of the flip frame 503. The side of the limiting support plate 511 away from the flip frame 503 is connected to the inner wall of the rectangular frame 501 through multiple springs, and multiple horizontal spring rods are evenly provided. Multiple spring cylinders 512 are fixed on the inner wall of the rectangular frame 501, and the spring rods are slidably connected in the spring cylinders 512.

[0084] At the loading station A, multiple tail shank portions 1001 are located between two clamping seats 504, and each tail shank portion 1001 is located between two corresponding V-grooves. The annular boss 1003 on the tail shank portion 1001 is located on the top of the clamping seat 504.

[0085] When the tail shank portion 1001 moves to the clamping position B, the adjusting gear 506 drives the adjusting screw 505 to rotate through the adjusting component 600, causing the adjusting blocks 507 and adjusting wheels 508 on both sides to move towards the center at the same time. Thus, through the action of the adjusting wheel 508 and the inclined surface of the adjusting groove, the clamping seat 504 is pushed to move towards the tail shank portion 1001, and then the tail shank portion 1001 is clamped and fixed by the clamping seats 504 on both sides, achieving the purpose of positioning.

[0086] At the flipping station D, the limiting support plate 511 and the convex strip are disengaged from the flipping frame 503 by the limiting cancellation structure, thus canceling their limiting effect. The flipping drive assembly 800 causes the moving plate 510 to drive the flipping rack 509 to move, which in turn causes the flipping gear 502 to drive the flipping frame 503, clamping seat 504 and tail shank 1001 to flip, so that the position of the tail shank 1001 is reversed to facilitate subsequent dispensing and fiber optic connection operations.

[0087] After the flip is completed, the limiting structure returns to its original position. Through the contact between the limiting support plate 511, the protrusion and the flip frame 503, its position is restricted to prevent it from rotating, thereby improving the positional stability of the flip frame 503 and the internal tail shank 1001.

[0088] The tilting drive assembly 800 includes two vertical third hydraulic rods 801 fixedly connected to the base frame 100. The top ends of the two third hydraulic rods 801 are jointly fixed to a lifting frame 802. The top of the lifting frame 802 is provided with a limit cancellation structure.

[0089] Two horizontal connecting rods 808 are symmetrically fixed on one side of the lifting frame 802. An inclined rotating cylinder 809 is rotatably connected to the outer end of the connecting rod 808. The rotating cylinder 809 is connected to a rotating rod through a spring. The outer ends of the two rotating rods extend out of the corresponding rotating cylinder 809 and are rotatably connected to a push wheel 810.

[0090] A push gear 811 is fixed at the bottom of the rotating cylinder 809. A horizontal push rack 812 meshes with the bottom of the push gear 811. The push rack 812 is slidably connected to the bottom of the connecting rod 808. A telescopic seat 813 is fixed between the two push racks 812. A telescopic hydraulic rod 814 is connected between the telescopic seat 813 and the lifting frame 802.

[0091] The limit cancellation structure includes two push plates 803 symmetrically located in the lifting frame 802. The middle part of the push plate 803 is inclined outward, and the lower part of the push plate 803 is connected to the lifting frame 802 by a spring. A horizontal sliding shaft 807 is also fixed on the side of the push plate 803 where the spring is located. The sliding shaft 807 passes through the side wall of the lifting frame 802 and is slidably connected to it. Two bidirectional cams 804 are symmetrically arranged between the lower parts of the two push plates 803. Two symmetrical protrusions are provided on the wheel surface of the bidirectional cams 804, and a fourth gear 805 is coaxially fixed at the bottom of the bidirectional cams 804. A fifth gear 806 is meshed between the two fourth gears 805. The fifth gear 806 is connected to a motor, and the motor is fixed to the lifting frame 802.

[0092] When the tailstock portion 1001 moves to the flipping station D, the lifting frame 802 and the push wheel 810 are moved upward by the third hydraulic rod 801. The push wheel 810 is located outside the moving plate 510, and the tops of the two push plates 803 are located inside the bottom of the limiting support plate 511. Through the drive of the motor and the transmission of the fourth gear 805 and the fifth gear 806, the two bidirectional cams 804 are rotated, so that the two push plates 803 move outward at the same time. At the same time, the tops of the push plates 803 push the limiting support plate 511 to move to both sides. The boss on the limiting support plate 511 disengages from the rectangular frame 501 and leaves enough space between the two limiting support plates 511.

[0093] After the limit is removed, the telescopic hydraulic rod 814 drives the telescopic seat 813 and the push gear 811 to move, thereby driving the push wheel 810 and the rotating cylinder 809 and other structures to move towards the rectangular frame 501. During the movement, the top of the push wheel 810 contacts the bottom of the second rotating platform 401, which limits the height position of the push wheel 810. The position of the push wheel 810 relative to the rotating cylinder 809 and other structures is automatically adjusted by the spring and the rotating rod. Then, during the movement of the push wheel 810, it contacts the moving plate 510 and pushes it to move inward into the rectangular frame 501. Then, the flipping rack 509 and the flipping gear 502 flip the flipping frame 503 and its internal structure.

[0094] After the flipping operation is completed, the push plate 803 returns to its original position through the rotation of the bidirectional cam 804 and the cooperation of the guide shaft 513, spring and other structures. This causes the limit support plate 511 and the convex strip to return to their original positions, and they contact the bottom sides of the flipping frame 503 again, providing limit support so that it cannot rotate. Then the push wheel 810 returns to its original position, and the lifting frame 802 moves down.

[0095] The base frame 100 is equipped with an adjustment component 600 at the fiber optic connection station F. The adjustment component 600 on the base frame 100 has the same structure as the adjustment component 600 on the rotating processing component 400, but is set in the opposite direction. This is so that after the fiber optic connection operation is completed, the internal structure of the flip-type tailstock positioning component 500 can be moved by the adjustment component 600 on the base frame 100, and the tightening and fixing of the tailstock part 1001 can be removed from it, and the processed ferrule part 1002 and the connected fiber optic cable can be taken out from it.

[0096] Example 2

[0097] The structure of this embodiment is basically the same as that of embodiment one, except that the core positioning assembly 300 includes a positioning seat 301 mounted on the rotating feeding assembly 200. The length direction of the positioning seat 301 coincides with the rotation radius direction of the rotating feeding assembly 200. The positioning seat 301 is provided with a plurality of stepped threaded holes evenly along the length direction and is threadedly connected to a threaded ring platform 304. An installation cylinder 303 is fixed inside the threaded ring platform 304. The top end of the installation cylinder 303 extends out of the positioning seat 301 and the bottom end is closed.

[0098] Two vertical limiting arc plates 306 are symmetrically arranged and slidably connected in the mounting cylinder 303. The top ends of the two limiting arc plates 306 extend out of the mounting cylinder 303 and are jointly fixed with an annular connecting plate 308. The bottom ends of the two limiting arc plates 306 pass through the bottom surface of the mounting cylinder 303 and extend out of the positioning seat 301. A spring base plate 305 is jointly fixed at the bottom ends. A spring connects the spring base plate 305 and the bottom end of the mounting cylinder 303.

[0099] The limiting arc plate 306 is provided with spring grooves on its opposite sides, and the limiting block 307 is slidably connected in the spring groove. The opposite sides of the two limiting blocks 307 are both set as V-shaped surfaces, and the other side is connected to the inner wall of the spring groove through a spring sheet.

[0100] When feeding the ceramic body of the insert part 1002, the ceramic body is inserted between the two limiting arc plates 306 and positioned between the two limiting blocks 307. Through the elastic action of the spring sheet, the limiting blocks 307 clamp the ceramic body to achieve elastic positioning. When the picking component 700 is above the positioning seat 301, the picking component 700 moves down and contacts the annular connecting plate 308 and presses it down. During the pressing process, the bottom end of the ceramic body is restricted by the bottom end of the mounting cylinder 303, and the two sides are restricted by the limiting blocks 307. Thus, during the downward movement of the annular connecting plate 308 and the limiting arc plates 306, the ceramic body is kept in a vertical state, and the upper part gradually enters the interior of the picking component 700 so that it can be clamped and transferred by the picking component 700 later.

[0101] The rotating feeding assembly 200 includes a support frame 101 fixed on the base frame 100. A vertical first fixed cylinder 102 is provided at the top center of the support frame 101. A rotating main shaft 203 is rotatably connected in the first fixed cylinder 102. A first rotating table 201 is fixed at the top of the rotating main shaft 203. Multiple mounting brackets 202 are evenly fixed along the circumferential direction on the outer side of the first rotating table 201. The positioning seat 301 of the insert positioning assembly 300 is provided with mounting grooves 302 on both sides. The mounting brackets 202 are fixedly installed in the mounting grooves 302. A first gear 204 is fixed at the bottom of the rotating main shaft 203. A second gear 205 meshes with one side of the first gear 204. The second gear 205 is connected to a motor, and the motor is fixedly connected to the support frame 101.

[0102] When feeding multiple insert parts 1002, the main shaft 203 drives the first rotating table 201 and multiple insert positioning components 300 on it to rotate through the drive of the motor and the transmission of the first gear 204 and the second gear 205. The rotation angle is half of the included angle between two adjacent mounting brackets 202, so that the insert positioning component 300 rotates to the material picking component 700 to pick up the material. Then it rotates again to make the position of the insert positioning component 300 offset from the position of the material picking component 700. The material picking component 700 drives the insert part 1002 to move down and perform insertion processing with the tail shank part 1001 on the rotating processing component 400.

[0103] Example 3

[0104] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the rotating processing assembly 400 includes a base 103 fixed to the top of the base frame 100. A vertical second fixed cylinder 104 is fixed in the middle of the top of the base 103. A drive cylinder 405 is rotatably connected in the second fixed cylinder 104. A second rotating platform 401 is fixed at the top of the drive cylinder 405. The second rotating platform 401 is provided with a rectangular groove corresponding to the position of each rectangular frame 501. The rectangular frame 501 is fixedly installed in the rectangular groove. A horizontal boss is fixed on the outside of the rectangular frame 501 and is connected to the second rotating platform 401 through the boss to provide limiting and support functions and improve the positional stability of the flip-type tailstock positioning assembly 500.

[0105] A first gear ring 406 is fixed on the outer side of the drive cylinder 405. A third gear 407 is meshed on one side of the first gear ring 406. The third gear 407 is connected to a motor, and the motor is fixed to the second fixed cylinder 104.

[0106] A vertical fixed shaft 402 is provided at the center of the drive cylinder 405. The bottom end of the fixed shaft 402 is fixedly connected to the base 103, and the top end passes through the drive cylinder 405 and the second rotating table 401 and is fixed to a fixed seat 403. Multiple fixed brackets 404 are fixed on the outer side of the fixed seat 403.

[0107] When switching the positions of multiple flip-type tailstock positioning components 500, the drive cylinder 405 drives the second rotating table 401 and multiple rectangular frames 501 on it to rotate through the drive of the motor and the transmission of the third gear 407 and the first gear ring 406. Each rotation switches the position, so that the flip-type tailstock positioning components 500 pass through six stations in sequence and perform corresponding operations.

[0108] Example 4

[0109] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the adjustment component 600 includes a first hydraulic rod 601 fixed to the bottom of the fixing frame 404. A horizontal lifting rod 602 is fixed to the bottom end of the first hydraulic rod 601. A bidirectional hydraulic rod 604 is provided in the middle of the bottom of the lifting rod 602. Vertical adjusting racks 603 are symmetrically fixed at both ends of the bidirectional hydraulic rod 604. Multiple teeth are evenly fixed on the opposite sides of the two adjusting racks 603. Two adjusting gears 506 are symmetrically located on both sides above the corresponding rectangular frame 501 and correspond to the positions of the two adjusting gears 506 in the rectangular frame 501.

[0110] When the flip-type tailstock positioning assembly 500 rotates to the clamping position B, the first hydraulic rod 601 drives the lifting rod 602 and the adjusting rack 603 to move downwards. The adjusting rack 603 meshes with the corresponding adjusting gear 506, and during the downward movement, it drives the adjusting gear 506 and the adjusting screw 505 to rotate. This causes the adjusting blocks 507 on both sides to drive the adjusting wheels 508 to move towards the center simultaneously. Through the action of the adjusting wheels 508 and the inclined sidewall of the adjusting groove, the position of the clamping seat 504 is adjusted so as to clamp and fix the tailstock part 1001 placed between the two clamping seats 504. After the positioning operation is completed, the bidirectional hydraulic rod 604 drives the adjusting racks 603 on both sides to move outwards, so that the adjusting racks 603 disengage from the adjusting gear 506, and then move back to their original position through the first hydraulic rod 601.

[0111] The material handling assembly 700 includes two second hydraulic rods 701 fixed to the bottom of the fixing frame 404. The bottom of the two second hydraulic rods 701 is fixed together to a material handling frame 702. The top of the material handling frame 702 is provided with a strip-shaped through groove 703, and two material handling seats 704 are symmetrically arranged inside. The material handling seats 704 are connected to the inner side wall of the material handling frame 702 through a plurality of evenly arranged hydraulic cylinders 705, and a plurality of V-shaped grooves are evenly arranged on the other side of the material handling seats 704.

[0112] During material handling, the two material handling seats 704 are located on the upper sides of the corresponding ceramic body. The second hydraulic rod 701 drives the material handling seats 704 to move down, so that the upper part of the ceramic body gradually enters the material handling frame 702 and is located between the two material handling seats 704. Then, the hydraulic cylinder 705 moves the material handling seats 704 on both sides to the middle at the same time, and clamps and fixes the ceramic body through the V-groove. Then, it moves up to return to its original position. When the rotating feeding assembly rotates and the position of the insert positioning assembly 300 after material handling is misaligned with the material handling assembly 700, the material handling assembly 700 drives the ceramic body to move down and presses the ceramic body onto the tail shank part 1001.

[0113] Example 5

[0114] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the glue injection assembly includes a glue tank 900 fixed to the bottom of the fixing frame 404. The bottom of the glue tank 900 is connected to a horizontal glue injection tube through a pump body. The bottom of the glue injection tube is evenly provided with multiple glue injection nozzles along the length direction. The position of the glue injection nozzles corresponds one-to-one with the position of multiple tail sections 1001 on the same flip-type tail section positioning assembly 500. The insertion channels 1005 of the multiple tail sections 1001 are glued through the pump body, glue injection tube and multiple glue injection nozzles to facilitate the subsequent connection of optical fibers.
