DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-14 This application is described in further detail.

[0033] The embodiment of the present application discloses an automated optical fiber assembly device.

[0034] Reference Figure 1The automated optical fiber assembly equipment includes a frame on which two symmetrical assembly stations are arranged.

[0035] Reference Figure 2-4 The feeding mechanism 1 includes a fixed frame 11, a movable plate 12 and a first clamping jaw 13, and the first cutting mechanism 2, a peeling mechanism 24, a cleaning mechanism 3, a second cutting mechanism 4, and a third cutting mechanism 5 are arranged in sequence along the length direction of the fixed frame 11.

[0036] A plurality of first clamps 13 are arranged at intervals along the length direction of the movable plate 12, and a clamping plate 131 is provided on the bottom surface of each first clamp 13. A clamping groove 111 for clamping and moving all the clamping plates 131 is opened on the inner wall of the fixed frame 11. The movable plate 12 is located below the clamping plate 131, and the movable plate 12 performs horizontal reciprocating motion through the linear module 121.

[0037] A shift fork 14 is provided on the top surface of the movable plate 12, and the shift fork 14 corresponds to the first clamping jaw 13 one by one. The shift fork 14 is swingably connected to the movable plate 12 through a mounting seat 15, and the mounting seat 15 is fixedly mounted on the top surface of the movable plate 12. The shift fork 14 is rotatably connected to the mounting seat 15 through a torsion spring, and the torsion spring applies a force to the shift fork 14 to make one end of the shift fork 14 close to the first clamping jaw 13 tilt upward, and after the end of the shift fork 14 close to the first clamping jaw 13 tilts upward, the adjacent first clamping jaw 13 can be moved along the direction from the first cutting mechanism 2 to the peeling mechanism 24. When the shift fork 14 moves along the direction from the peeling mechanism 24 to the first cutting mechanism 2 to reset, the shift fork 14 rotates downward when one end of the shift fork 14 close to the adjacent first clamping jaw 13 contacts the first clamping jaw 13 in the reset direction.

[0038] The moving plate 12 controls each fork 14 to move along the direction from the first cutting mechanism 2 to the peeling mechanism 24 first, an original empty position is set on the side of the first cutting mechanism 2 away from the peeling mechanism 24, an empty position 1 is set between the peeling mechanism 24 and the cleaning mechanism 3, an empty position 2 is set between the cleaning mechanism 3 and the second cutting mechanism 4, an empty position 3 is set between the second cutting mechanism 4 and the third cutting mechanism 5, and a final empty position is set on the side of the third cutting mechanism 5 away from the second cutting mechanism 4. When the moving plate 12 moves along the direction from the first cutting mechanism 2 to the peeling mechanism 24, the fork 14 pushes the adjacent first clamping jaw 13 to move along the direction from the first cutting mechanism 2 to the peeling mechanism 24, so that the first clamping jaw 13 at the original empty position moves to the first cutting mechanism 2 The first clamping jaw 13 at the first cutting mechanism 2 moves to the peeling mechanism 24, the first clamping jaw 13 at the peeling mechanism 24 moves to the first empty position, the first clamping jaw 13 at the first empty position moves to the cleaning mechanism 3, the first clamping jaw 13 at the cleaning mechanism 3 moves to the second empty position, the first clamping jaw 13 at the second empty position moves to the second cutting mechanism 4, the first clamping jaw 13 at the second cutting mechanism 4 moves to the third empty position, the first clamping jaw 13 at the third empty position moves to the third cutting mechanism 5, the first clamping jaw 13 at the third cutting mechanism 5 moves to the final empty position, the card slots 111 at the original empty position and the final empty position both pass through the top surface of the fixed frame 11, and the first clamping jaw 13 at the final empty position is moved to the original empty position by the manipulator; Then the moving plate 12 controls each fork 14 to move to reset along the direction from the stripping mechanism 24 to the first cutting mechanism 2, and the fork 14 rotates downward when one end close to the adjacent first clamping jaw 13 contacts the first clamping jaw 13 in the reset direction, until the fork 14 finally moves to reset. Since the first clamping jaw 13 is heavier as a whole and the friction between the clamping plate 131 and the clamping slot 111 is large, when the first clamping jaw 13 is passed by the upturned end of the fork 14, the first clamping jaw 13 can still remain stable without displacement. This cycle is repeated to realize automated loading and simultaneous operation of multiple mechanisms on corresponding optical fiber segments, and multiple optical fiber segments can be subjected to different operations at the same time, thereby improving the efficiency of optical fiber assembly.

The first cutting knife 22 cuts the optical fiber on the first workbench 211 when it swings, and then the first movable frame 21 moves toward the direction close to the fixed frame 11 until the first clamp 13 at the first cutting assembly can clamp the optical fiber section.

The translation assembly 712 includes a screw module 7121, a sliding plate 7122, and a 7-type plate 7123. The sliding plate 7122 is connected to the slide of the screw module 7121 through a transition plate 714. The transition plate 714 is fixedly connected to the slide of the screw module 7121.

The sliding plate 7122 is fixedly connected to the output end of the lifting cylinder 713.

[0053] The lead screw module 7121 drives the transition plate 714 to slide along the length direction of the conveying frame 711, and the transition plate 714 then drives the sliding plate 7122 to slide along the length direction of the conveying frame 711 through the lifting cylinder 713, and the lifting cylinder 713 also drives the sliding plate 7122 to rise and fall. The 7-type plate 7123 is fixedly connected to the sliding plate 7122 and is arranged at intervals along the length direction of the sliding plate 7122. A metal fixed block 7111 and a movable carrier 7112 are arranged on the top surface of the conveying frame 711. A plurality of fixed blocks 7111 are arranged equidistantly along the length direction of the sliding plate 7122. The movable carrier 7112 is placed on the top surface of the fixed block 7111 and is detachable from the fixed block 7111. The 7-type plate 7123 is located below the top plate of the conveying frame 711. A first lifting groove for lifting and lowering the 7-type plate 7123 is provided on the top plate of the conveying frame 711. A second lifting groove corresponding to the first lifting groove is provided on the fixed block 7111. After passing through the first lifting groove and the second lifting groove, the 7-type plate 7123 contacts the movable carrier 7112 and lifts the movable carrier 7112 upward.

[0054] The sliding plate 7122 rises and drives the corresponding movable module 7112 to rise through the 7-type plate 7123, and then the sliding plate 7122 moves in the direction close to the wire pulling mechanism 8, so that a movable carrier 7112 away from the wire pulling mechanism 8 moves to the position where an adjacent movable carrier 7112 just exists, and then the sliding plate 7122 descends, and finally the sliding plate 7122 moves in the direction away from the wire pulling mechanism 8 to its original position.

[0055] A plurality of shells used in conjunction with optical fibers are placed on the movable carrier 7112, and resin for fixing the optical fibers is arranged inside the shells. An electric heating wire is arranged inside the fixing block 7111, and when the fixing block 7111 is heated, the movable carrier 7112 is heated, and when the movable carrier 7112 is heated, the resin inside the shells melts.

[0056] Reference Figure 11-12 The threading mechanism 7 includes a positioning assembly 72 and a threading assembly 73 . The positioning assembly 72 is disposed on the conveying frame 711 , and the threading assembly 73 is disposed on a side of the optical fiber transfer streamline 62 away from the conveying frame 711 .

[0057] The threading assembly 73 includes a movable module 731 and a threading clamp 732. The movable module 731 includes a second horizontal linear module 7311, a second lifting linear module 7312 and a third horizontal linear module 7313. The slide of the second horizontal linear module 7311 slides along the length direction of the movable carrier 7112, and the slide of the third horizontal linear module 7313 slides toward or away from the conveying frame 711.

[0058] The frame of the second horizontal linear module 7311 is installed on the top surface of the frame, and the second lifting linear module 7312 and the third horizontal linear module 7313 are each provided with two groups. The frames of the two second lifting linear modules 7312 are simultaneously provided on the slide of the second horizontal linear module 7311 through a synchronization plate, and the frames of the two third horizontal linear modules 7313 are respectively provided on the slides corresponding to the two groups of second lifting linear modules 7312.

[0059] The threading clamps 732 are disposed on slides corresponding to the two sets of third horizontal linear modules 7313 , and three optical fiber segments are spaced between the two optical fiber segments operated by the two threading clamps 732 .

The frame of the fourth horizontal linear module 721 is fixed on the conveying frame 711, the connecting frame 722 is fixed on the slide of the fourth horizontal linear module 721, and the pressure sensor 723 is arranged on the connecting frame 722. The pressure sensor 723 is located on the side of the movable carrier 7112 away from the threading clamp 732. The optical fiber segment operated by the threading clamp 732 passes through the shell and abuts against the corresponding pressure sensor 723. When the pressure detected by the pressure sensor 723 exceeds the set value, the threading clamp 732 pulls the optical fiber segment back for re-threading. If the threading fails three times, the re-threaded optical fiber segment and the optical fiber assembly of the shell are judged as unqualified and recorded in the data system.

[0061] Reference Fig.13 The wire pulling mechanism 8 includes a fifth horizontal linear module 81, a third lifting linear module 82, and a wire pulling clamp 83. A heightening platform 84 is provided on the top surface of the frame. The frame of the fifth horizontal linear module 81 is provided on the heightening platform 84, the frame of the third lifting linear module 82 is provided on the slide of the fifth horizontal linear module 81, and the wire pulling clamp 83 is installed on the slide of the third lifting linear module 82. Two groups of wire pulling mechanisms 8 are provided, and the horizontal movement strokes of the wire pulling clamps 83 of the two groups of wire pulling mechanisms 8 are independently set.

[0062] The visual inspection mechanism includes a camera 85, which is electrically connected to a computing system. The camera 85 captures the movable carrier 7112 located in front of the elevated platform 84 and sends the image to the computing system. A slit is provided on the upper side of the shell, and the camera 85 can capture the position of the end of the optical fiber segment away from the wire-pulling clamp 83 in the shell through the slit. The computing system calculates the travel that the wire-pulling clamp 83 needs to move based on the initial position of the optical fiber segment and the final position that the end of the optical fiber segment needs to reach away from the wire-pulling clamp 83, so as to ensure that the position of the end of the optical fiber segment away from the wire-pulling clamp 83 in the shell reaches a qualified level.

[0063] If the distance between the end of the optical fiber segment close to the wire clamp 83 and the movable carrier 7112 is less than the set value, the wire clamp 83 pulls the optical fiber segment again until the distance between the end of the optical fiber segment close to the wire clamp 83 and the movable carrier 7112 reaches the qualified range.

[0064] If the distance between the end of the optical fiber segment close to the wire clamp 83 and the movable carrier 7112 is greater than the set value, the optical fiber assembly is judged as unqualified and recorded in the data system.

[0065] A laser cutting head 86 is also disposed on the elevated platform 84 . The laser cutting head 86 moves along the length direction of the movable carrier 7112 . The laser cutting head 86 cuts the end of the optical fiber segment close to the wire clamp 83 according to the set data.

[0066] The computing system calculates the travel distance that the wire-pulling clamp 83 needs to move according to the initial position of the optical fiber segment and the final position that the end of the optical fiber segment away from the wire-pulling clamp 83 needs to reach. The wire-pulling clamp 83 moves toward the direction close to the movable carrier 7112 and then descends and clamps the optical fiber segment. Then the wire-pulling clamp 83 pulls the optical fiber segment so that the position of the end of the optical fiber segment away from the wire-pulling clamp 83 in the shell reaches an acceptable level. Since there is an error in the movement of the wire-pulling clamp 83 and the distance that the optical fiber segment needs to move is very small, the camera 85 takes a picture of the optical fiber segment again. If the distance between the end of the optical fiber segment close to the wire-pulling clamp 83 and the movable carrier 7112 is less than a set value, the wire-pulling clamp 83 pulls the optical fiber segment again until the distance between the end of the optical fiber segment close to the wire-pulling clamp 83 and the movable carrier 7112 reaches an acceptable range. If the distance between the end of the optical fiber segment close to the wire-pulling clamp 83 and the movable carrier 7112 is greater than a set value, the optical fiber assembly is judged to be unqualified and recorded in the data system, thereby improving the assembly accuracy of the optical fiber.

[0067] Reference Fig.14 The substitute mechanism 9 includes a substitute conveyor belt 91, a replacement robot 92, a discharge robot 93, and a waste conveyor belt 94. The substitute conveyor belt 91 is provided with a substitute carrier, and the substitute carrier is provided with assembled qualified optical fiber components. The discharge robot 93 clamps the corresponding unqualified optical fiber components to the waste conveyor belt 94 according to the unqualified information provided by the data system, and then the replacement robot 92 clamps the qualified optical fiber components on the substitute conveyor belt 91 to the empty position on the movable carrier 7112.

[0068] The unloading robot 93 grabs the integral movable carrier 7112 filled with qualified optical fiber components and places it on the qualified product conveyor belt 95 .

[0069] Since the optical fiber components have multiple subsequent processing steps, the replacement mechanism 9 replaces all unqualified optical fiber components with qualified ones to facilitate connection with subsequent processing steps.

[0070] The implementation principle of an automated optical fiber assembly device in the embodiment of the present application is as follows: When the first cutting knife 22 swings, it cuts the optical fiber on the first workbench 211, and then the first movable frame 21 moves toward the direction close to the fixed frame 11 until the first clamp 13 at the first cutting assembly can clamp the optical fiber segment, and then the auxiliary air clamp 23 releases the optical fiber segment, and the first clamp 13 clamps the optical fiber segment, and finally the first movable frame 21 moves to its original position in the direction away from the fixed frame 11, and the first clamp 13 moves to the stripping mechanism 24 with the cut optical fiber segment.

[0071] When the first clamping jaw 13 moves to the cleaning mechanism 3 with the stripped optical fiber segment, there is space between the upper cleaning cloth and the lower cleaning cloth, and the third movable frame 31 moves toward the direction close to the fixed frame 11 so that the optical fiber segment is located between the upper cleaning cloth and the lower cleaning cloth, and then the first lifting plate 34 and the second lifting plate 35 slide toward each other until they abut between the upper and lower pressing rollers 33, and then the upper cleaning cloth and the lower cleaning cloth move in opposite directions to wipe and clean the optical fiber segment, and then the first lifting plate 34 and the second lifting plate 35 slide toward the direction away from each other until the upper and lower pressing rollers 33 separate, and the third movable frame 31 moves to its original position in the direction away from the fixed frame 11, and the first clamping jaw 13 moves to the second empty position with the cleaned optical fiber segment.

[0072] The first clamping jaw 13 clamps the cleaned optical fiber segment and moves it to the second cutting mechanism 4, and the fourth movable frame 41 moves toward the direction close to the fixed frame 11, so that the optical fiber segment is located above the second cutting knife 42, and then the upper clamping plate 43 is rotated until the bottom surface of the upper clamping plate 43 is in contact with the outer periphery of the second cutting knife 42, and the second cutting knife 42 cuts off the end of the optical fiber segment when sliding, so that the part of the optical fiber segment cut by the first cutting knife 22 is smoother, reducing burrs, and improving the smoothness of the subsequent optical fiber segment passing into the shell.

[0073] While the positioning air clamp 51 clamps the optical fiber segment, the upper blade 521 and the lower blade 522 cut off the unstripped portion near the middle of the optical fiber segment, thereby making the optical fiber segment a completely stripped optical fiber, and the cut unstripped portion falls into the waste box 53 to keep the equipment clean.

[0074] The second clamping claw 613 clamps the optical fiber segment cut by the third cutting mechanism 5, and the moving module 61 moves the optical fiber segment to the intermediate transfer tool 623 at the optical fiber transfer streamline 62 for preparation of threading.

[0075] When the intermediate transfer gear 623 and the movable carrier 7112 are moved to correspond to the threading clamp 732, the movable module 731 runs and controls the threading clamp 732 to move in the direction close to the movable carrier 7112, and then the threading clamp 732 clamps the optical fiber segment and passes the optical fiber segment through the corresponding shell. Since the threading stroke of the threading clamp 732 is fixed, when the pressure detected by the pressure sensor 723 exceeds the set value, it means that the angle or position of the optical fiber threading is incorrect. The threading clamp 732 pulls the optical fiber segment back for re-threading until the pressure detected by the pressure sensor 723 enters the normal range. If the threading fails three times, the re-threaded optical fiber and the optical fiber assembly of the shell are judged as unqualified, and the replacement mechanism is used to replace the prepared qualified optical fiber assembly.

[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
