Description

Technical Field

[0001] This invention belongs to the field of optical cable processing and manufacturing, and specifically relates to a cable threading device. Background Technology

[0002] In the assembly process of many cable connectors, it is usually necessary to manually strip the cable, then merge the sub-cables together, and then manually thread the sub-cables onto the required components of the connector.

[0003] Typically, cable connectors require springs and rubber sleeves to be threaded through the cable. Due to the precision limitations of cable connectors, the actual size of the rubber sleeve and the cable is not significantly different. This causes friction between the rubber sleeve and the cable surface during the threading process. The material used for the rubber sleeve has high friction, which makes the cable easily bend and arch during the threading process. This prevents the rubber sleeve from moving in the preset direction, resulting in threading failure. Therefore, the current method of threading cables with rubber sleeves has a low degree of automation and low threading efficiency. Summary of the Invention

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a cable threading device to solve the problem of low positioning and threading efficiency of rubber sleeves and cables in existing cable connectors.

[0019] As a further improvement of the present invention, it includes a material fixing component, which is disposed on one side of the clamping seat where the clamping rod protrudes, and the lifting part swings around the material fixing component.

[0020] As a further improvement of the present invention, the pushing part and the clamping part are arranged adjacent to each other, and the pushing part is provided with a clamping handle at one end facing the clamping part. One end of the clamping handle is connected to the pushing part, and the other end extends towards the clamping part. The clamping handle is located between the material fixing assembly and the clamping part.

[0021] As a further improvement of the present invention, an air blowing section is included, which is disposed on the lifting section, and the air outlet of the air blowing section faces the incoming material fixing assembly.

[0022] As a further improvement of the present invention, the material receiving fixing component is provided with a first pressure cover, the first pressure cover is detachably connected to the material receiving fixing component, the first pressure cover and the material receiving fixing component cooperate to form a fixing groove, and the opening direction of the fixing groove is set towards the pushing part.

[0032] When the lifting part is in the first position, the second driving component pushes the two clamping rods of the pushing part, so that the clamping handles of the two clamping rods move toward the fixed groove along the straight line formed by the fixed groove and the jaw head of the clamping part; the clamping gap between the two clamping rods is greater than the gap between the two jaw heads.

[0033] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0034] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include:

[0035] (1) The cable threading device of the present invention is provided with a clamping part and a pushing part. The clamping part clamps the end of the cable sub-cable, and the lifting part drives the clamping part and the pushing part to rise, so that the end of the sub-cable is raised, avoiding interference between the rubber sleeve and the first spring and the incoming material fixing component during the pushing process, and facilitating the pushing part to push the rubber sleeve and the first spring to a predetermined position, so as to realize the automatic threading of the first spring and the rubber sleeve on the cable.

[0036] (2) The cable threading device of the present invention sets the pushing part in the form of two clamping rods, uses the clamping gap between the two clamping rods to pass the cable through, and then the end of the clamping rod abuts against the rubber sleeve, and then the clamping rod is driven to move by the second driving component. The setting of the clamping gap avoids interference between the pushing part and the cable during the pushing process, and can effectively push the rubber sleeve to the preset position, thereby realizing the automation of cable threading.

[0037] (3) The cable threading device of the present invention is provided with a sliding groove seat, and a protrusion is provided on the sliding groove seat, and a corresponding groove is provided on the clamping rod. When the protrusion and the groove cooperate with each other, the two clamping rods are in a straight state. When the second drive component pushes the two clamping rods to move, the protrusion and the groove separate, the protrusion abuts against the straight area of ​​the clamping rod, the two clamping rods close together, the gap of the clamping gap is reduced, and the two clamping rods complete the clamping of the rubber sleeve, which facilitates the push part to push the rubber sleeve to move.

[0038] (4) The cable threading device of the present invention is provided with a gripper head, a gripper top rod and a third drive assembly. The gripper top rod abuts against the swing gap at one end of the two gripper heads, and the wedge-shaped surface at the end of the gripper top rod pushes the swing gap at one end of the two gripper heads to expand, so that the swing gap at the other end of the two gripper heads is correspondingly reduced, thereby achieving the clamping of the cable.

[0039] (5) The cable threading device of the present invention provides a guide plate on one side of the lifting part and a corresponding slider on the clamp. The first rotating shaft on the slider is inserted into the first arc groove on the guide plate to limit the swing trajectory of the lifting part, ensuring that the swing trajectory of the lifting part is strictly controllable during the movement of the pushing part and the clamping part, so as to facilitate the automation of cable threading by the cable threading device.

[0040] (6) The cable threading device of the present invention provides a material fixing component on one side of the clamp seat to clamp and fix the cable, which facilitates the determination of the insertion position of the rubber sleeve and the first spring; at the same time, when the lifting part drives the clamping part to move, the end of the cable is raised accordingly, so as to avoid the bottom of the cable resting on the material fixing component and affecting the insertion of the rubber sleeve and the first spring.

[0041] (7) The cable threading device of the present invention provides a detachable first pressure cover on the incoming material fixing component and a corresponding cover removal claw. The fixing groove formed by the first pressure cover and the incoming material fixing component can accurately position the rubber sleeve at the threading position. The cover removal claw can remove the first pressure cover after the rubber sleeve is threaded in place, which facilitates the subsequent processes of the cable connector.

[0059] Example:

[0060] Please see Figures 1-8 In a preferred embodiment of the present invention, the cable threading device includes a lifting part, which includes a clamping seat 9, a pushing part 3 and a clamping part 10 disposed on the clamping seat 9; wherein, the clamping part 10 is used to clamp one end of the cable 19, and the pushing part 3 is used to push the cable threading component along the cable 19; and the lifting part is also provided with a first driving component 11, which is used to drive the lifting part to swing.

[0061] Specifically, the cable threading device in this application is mainly used to thread the cable threading component onto the cable 19. The cable threading component includes a rubber sleeve 22 and a first spring 21. It fixes the end of the cable 19 through the clamping part 10, and then drives the cable 19 to swing through the first driving component 11 on the lifting part, so that the cable 19 is tilted towards the pushing part 3. After the end of the cable 19 tilts, it separates from the placement platform of the cable 19, so that the first spring 21 and the rubber sleeve 22 will not interfere with the placement platform during the threading process, and it is convenient for the rubber sleeve 22 and the first spring 21 to be threaded into the preset position.

[0062] In this application, the stripped portion of the cable 19 is the sub-cable 20. The cable 19 and the sub-cable 20 are a single unit, and the portion where the first spring 21 and the rubber sleeve 22 are fitted is the sub-cable 20. For ease of description in the following text, the cable 19 and the stripped sub-cable 20 will be collectively referred to as cable 19.

[0063] For clarity, a lifting coordinate system is set up in the lifting section, with the first coordinate axis being the length direction of the clamping section, the second coordinate axis being the width direction of the clamping section, and the third coordinate axis being the vertical direction perpendicular to the platform of the clamping seat 9.

[0064] Furthermore, as a preferred embodiment of the present invention, the pushing part 3 in this application includes two opposing clamping rods 302, with a clamping gap between the two clamping rods 302; one end of each clamping rod 302 protrudes from the clamping seat 9 along the first coordinate axis direction of the lifting part coordinate system, and the other end is connected to a second driving component 305 that reciprocates along the first direction of the lifting part coordinate system. In this application, by using two opposing clamping rods 302 and leaving a clamping gap between them, when the sub-cable 20 is actually inserted, the sub-cable 20 passes through the clamping gap, and the ends of the two clamping rods 302 (protruding from the clamping seat 9) abut against the rubber sleeve 22. The second driving component 305 pushes the rubber sleeve 22 to move along the first direction, pushing the rubber sleeve 22 to a predetermined position. Since the outer circumferential dimension of the rubber sleeve 22 is larger than that of the first spring 21, the rubber sleeve 22 pushes the first spring 21 to a preset position when it moves along the first direction to the predetermined position.

[0065] More preferably, the pushing part 3 in this application also includes a sliding seat 301, the two clamping rods 302 are both disposed in the sliding seat 301, and the sliding seat 301 has an opening for the two clamping rods 302 to extend out; the sliding seat 301 has a protrusion 306 on at least one side facing the two clamping rods 302, and a groove is correspondingly provided on the two clamping rods 302, the protrusion 306 and the groove correspondingly cooperate.

[0066] When using the two clamping rods 302 to push the rubber sleeve 22, since the rubber sleeve 22 itself is small, it is difficult to push the rubber sleeve 22 by abutting alone. The clamping rods 302 are needed to clamp and push the rubber sleeve 22. Therefore, this application provides a corresponding sliding seat 301 to ensure the stable pushing of the clamping rods 302. A protrusion 306 is provided on the sliding seat 301, and a groove is provided on the clamping rods 302. When the clamping rods 302 move in the first direction, the protrusion 306 and the groove are matched and disengaged accordingly, realizing the corresponding opening and clamping of the clamping rods 302, that is, the loosening and clamping of the rubber sleeve 22.

[0067] Correspondingly, the rubber sleeve 22 threaded onto the sub-cable 20 of this application has a stepped collar at one end facing the clamping rod 302. When the clamping rod 302 clamps, the end of the clamping rod 302 abuts against the stepped structure of the rubber sleeve 22, thereby clamping the rubber sleeve 22 and pushing it along the first direction. Preferably, in this application, the sliding seat 301 has protrusions 306 on both sides facing the clamping rod 302, and the two clamping rods 302 have corresponding grooves, so that when the second drive assembly 305 pushes the clamping rods 302 to move, the two clamping rods 302 simultaneously clamp the rubber sleeve 22.

[0068] Furthermore, as a preferred embodiment of the present invention, a push block 303 is also provided between the clamping rod 302 and the second drive assembly 305. The push block 303 is connected to the drive shaft of the second drive assembly 305, and the two clamping rods 302 are connected to the push block 303 through a spring sheet 304. Since the clamping rods 302 in this application need to clamp the rubber sleeve 22, if the two clamping rods 302 are directly connected to the second drive assembly 305, they cannot complete the clamping action. Therefore, the push block 303 and the spring sheet 304 are provided. When the protrusion 306 on the slide seat 301 squeezes the clamping rod 302 and causes the clamping rods 302 to move relative to each other, the spring sheet 304 can bend accordingly, thereby reducing the clamping gap between the two clamping rods 302.

[0069] Preferably, a second spring 307 is provided between the two clamping rods 302 in this application. The two ends of the second spring 307 are respectively connected to the two clamping rods 302 and are used to apply elastic force to the two clamping rods 302. When the clamping rods 302 move to the point where the groove on them corresponds to the protrusion 306 on the slide seat 301, the two clamping rods 302 return from the clamped state to the open state.

[0070] Furthermore, in this application, a guide plate 14 is provided on one side of the lifting part, and a slider 12 is correspondingly provided on one side of the clamp 9. The slider 12 is provided with a first rotating shaft 13 along the second direction of the coordinate system of the lifting part. A first arc-shaped groove 15 is provided on the guide plate 14, and the first rotating shaft 13 partially passes through the first arc-shaped groove 15. By providing a slider 12 corresponding to one side of the clamp 9 and providing a first rotating shaft 13 on the slider 12, and using the first arc-shaped groove 15 on the guide plate 14 to limit the rotation trajectory of the first rotating shaft 13, this application further limits the swing trajectory of the lifting part, realizes controllable swing trajectory during the installation of the sub-cable 20, ensures that the rubber sleeve 22 pushes the same installation trajectory each time, avoids the problem of interference between the rubber sleeve 22 and the sub-cable 20 caused by different swing trajectories during each installation of the rubber sleeve 22, and improves the installation efficiency of the rubber sleeve 22.

[0071] Preferably, the center of the first arc-shaped groove 15 is located on the end face of the fixed groove facing the pushing part 3. The protruding port of the cable 19 is located exactly on the end face of the fixed groove facing the pushing part 3. When the center of the first arc-shaped groove 15 is exactly located on the end face of the fixed groove facing the pushing part 3, the swing center of the pushing part 3 is exactly the swing end point of the sub-cable 20, so that the swing trajectory of the sub-cable 20 is controllable.

[0072] More preferably, the guide plate 14 of this application is further provided with a second arc-shaped groove 16, which is concentrically arranged with the first arc-shaped groove 15. Simultaneously, the slider 12 is provided with a second rotating shaft 17 in the second direction of the lifting part coordinate system, and the second rotating shaft 17 partially passes through the second arc-shaped groove 16. The second arc-shaped groove 16 has the same function as the first arc-shaped groove 15; through the cooperation of the first arc-shaped groove 15 and the second arc-shaped groove 16, the swing trajectory of the lifting part is precisely limited.

[0073] Preferably, the lifting part in this application further includes a swing angle platform 8, on which the aforementioned clamp 9, pushing part 3, clamping part 10, and guide plate 14 are all disposed. The clamp 9 is used to cooperate with the first drive assembly 11 to drive the pushing part 3 and clamping part 10 as a whole to move. The swing angle platform 8 is a support platform used to place the aforementioned structural components.

[0074] More preferably, the slider 12 in this application is further provided with an adjusting arm 18. The first rotating shaft 13 is an eccentric shaft, and an installation notch is provided on the eccentric shaft. One end of the adjusting arm 18 is engaged in the installation notch, and the other end extends freely. By rotating the adjusting arm 18, the adjusting arm 18 drives the first rotating shaft 13 to rotate, so that the first rotating shaft 13 is pressed into the first arc-shaped groove 15, thereby improving the accuracy of the swing amplitude of the clamping part 10. Preferably, the adjusting arm 18 extends towards the slider 12 and is fixed to the slider 12 by screws. When it is necessary for the adjusting arm 18 to rotate, by tightening or loosening the screws, the screws force the adjusting arm 18 to rotate, thereby realizing the rotation of the first rotating shaft 13.

[0075] Further preferably, this application also includes a material fixing component 1, which is disposed on one side of the clamping base 9 where the clamping rod 302 protrudes, and the lifting part swings around the material fixing component 1. The material fixing component 1 is mainly used to fix and place the cable 19 so as to facilitate the swinging and threading of the sub-cable 20. The material fixing component 1 has a placement groove 7 for placing the cable 19, and the center line of the cable 19 is flush with the plane of the material fixing component 1. The sub-cable 20 is assembled with a core structure in a subsequent process, and the core moves along the axial direction of the cable 19 on the material fixing component 1 and is assembled with the sub-cable 20. The sub-cable 20 needs to be flat and have a strip structure on the material fixing component 1, but the sheath of the cable 19 itself has a certain thickness, and there is a height difference between the sub-cable 20 and the material fixing component 1, which can easily cause the sub-cable 20 to bend. Therefore, a placement groove 7 is provided on the incoming material fixing component 1. By placing the cable 19 in the placement groove 7 and placing the sub-cable 20 on the incoming material fixing component 1, the sub-cable 20 is prevented from being bent excessively.

[0076] More preferably, the swing angle of the clamping part 10 in this application is between 15° and 30°. When the swing angle of the clamping part 10 is too small, it will cause interference between the pushing part 3 and the table surface of the incoming material fixing component 1 when pushing; when the swing angle of the clamping part 10 is too large, the bending arc of the sub-cable 20 is too large, and the pushing part 3 will jam the rubber sleeve 22. Optionally, the swing angle of the clamping part 10 in this application can be adjusted according to the actual size of the cable 19, the insertion position of the rubber sleeve 22, etc., and the clamping angle of the clamping part 10 includes, but is not limited to, the above-mentioned swing range.

[0077] More preferably, the clamping part 10 in this application includes a gripper head 1001, a gripper top rod 1002, and a third drive assembly 1003 arranged sequentially along the first direction of the lifting part coordinate system. The gripper heads 1001 are arranged in pairs, with a swing gap between the two gripper heads 1001. A pivot pin 1004 is provided on each of the two gripper heads 1001, and the two gripper heads 1001 can swing by their respective pivot pins 1004. One end of the gripper top rod 1002 is arranged towards the swing gap, and the other end is connected to the third drive assembly 1003. The driving direction of the third drive assembly 1003 is the same as the arrangement direction of the gripper top rod 1002. The end of the gripper head 1001 facing the gripper top rod 1002 is inclined, and the wedge-shaped surface of the gripper top rod 1002 is in contact with the inclined surface of the gripper head 1001. The clamping part 10 is mainly used to clamp the sub-cable 20 (not the rubber sleeve 22). In this application, the third drive assembly 1003 drives the jaw push rod 1002 to move toward the two jaw heads 1001. The wedge-shaped surface of the jaw push rod 1002 abuts against the inclined surface of the two jaw heads 1001. The two jaw heads 1001 swing around the pivot pin 1004, so that the two jaw heads 1001 move toward each other on the side away from the third drive assembly 1003 to achieve the clamping operation.

[0078] Preferably, a third spring 1005 is provided between the two gripper heads 1001. The third spring 1005 has the same function as the second spring 307, which is used to open up the ends of the two gripper heads 1001 that are clamped together when the gripper push rod 1002 exits the swing gap between the two gripper heads 1001.

[0079] Furthermore, in this application, the pushing part 3 is arranged adjacent to the clamping part 10, and the pushing part 3 has a clamping handle 308 at one end facing the clamping part 10. One end of the clamping handle 308 is connected to the pushing part 3, and the other end extends towards the clamping part 10. The clamping handle 308 is located between the material fixing assembly 1 and the clamping part 10. In the cable threading device of this application, the clamping part 10 is used to fix the end of the sub-cable 20, and the pushing part 3 is used to push the rubber sleeve 22 along the extension direction of the sub-cable 20. Both are arranged along the sub-cable 20. In order to avoid interference between the main body of the pushing part 3 and the clamping part 10, the pushing part 3 and the clamping part 10 are arranged adjacent to each other, and a clamping handle 308 is provided at one end of the pushing part 3 facing the clamping part 10. By extending the clamping handle 308 in front of the clamping part of the clamping part 10, the clamping handle 308 can push the rubber sleeve 22 along the arrangement direction of the sub-cable 20. Preferably, the clamping handle 308 moves between the fixed slot and the gripper head 1001 along the first direction of the lifting coordinate system.

[0080] More preferably, this application also includes an air blowing section 4, which is also disposed on the lifting section, and the air outlet of the air blowing section 4 is disposed facing the material fixing assembly 1. By providing the air blowing section 4, this application uses the airflow blown by the air blowing section 4 to push the first spring 21 to a preset position, so as to facilitate the rubber sleeve 22 to be pushed to the preset position.

[0081] Furthermore, the incoming material fixing component 1 in this application is provided with a first pressure cover 2, which is detachably connected to the incoming material fixing component 1. The first pressure cover 2 and the incoming material fixing component 1 cooperate to form a fixing groove, and the opening direction of the fixing groove is set towards the pushing part 3. During the installation of the cable connector, it is necessary to push the first spring 21 and the rubber sleeve 22 to a preset position. In order to control the pushing part 3 to push the rubber sleeve 22 to the preset position, the first pressure cover 2 and the incoming material fixing component 1 form a fixing groove. When the rubber sleeve 22 is pushed to the fixing groove, the rubber sleeve 22 is blocked by the fixing groove and stops, so as to push the rubber sleeve 22 to the preset installation position. Correspondingly, the first pressure cover 2 is provided with a notch facing the incoming material fixing component 1, and the incoming material fixing component 1 is provided with a protrusion facing the first pressure cover 2. The notch and the protrusion cooperate to form the fixing groove.

[0082] Preferably, the first pressure cap 2 in this application is provided with a magnetic attraction structure, and the material receiving and fixing component 1 is correspondingly provided with a magnetic attraction structure. The magnetic attraction structure allows the first pressure cap 2 to be tightly attached to the material receiving and fixing component 1 when the two are closed, thereby fixing the rubber sleeve 22 at the placement slot. Simultaneously, the magnetic attraction structure facilitates the fixing and separation of the first pressure cap 2 and the material receiving and fixing component 1. Of course, in addition to the magnetic attraction structure, other mechanical connection structures, such as slots and elastic buckles, can also be used between the first pressure cap 2 and the material receiving and fixing component 1.

[0083] Furthermore, the incoming material fixing assembly 1 in this application is also provided with a second pressure cover 6, which is disposed adjacent to the first pressure cover 2. The contact end face of the second pressure cover 6 and the first pressure cover 2 is flush with the stripped end face of the cable 19 and the sub-cable 20. Since the first pressure cover 2 and the incoming material fixing assembly 1 are detachably assembled, when the pushing part 3 pushes the rubber sleeve 22 to the placement slot, the first pressure cover 2 needs to be separated from the incoming material fixing assembly 1. When the rubber sleeve 22 moves to the placement slot, the first pressure cover 2 is then closed on the incoming material fixing assembly 1. When the first pressure cover 2 is separated from the incoming material fixing assembly 1, the cable 19 itself has no fixing structure, which causes the position of the cable 19 to be uncontrollable when the clamping part 10 drives the exposed end of the sub-cable 20 to rise. The cable 19 will be lifted up with the sub-cable 20, which is inconvenient for the rubber sleeve 22 to be fitted. Therefore, a second pressure cap 6 is provided. The second pressure cap 6 cooperates with the incoming material fixing component 1 to fix the cable 19, so that the clamping part 10 only needs to be lifted by a small amount, and the pushing part 3 can push the rubber sleeve 22 to the predetermined position. Preferably, the end face where the second pressure cap 6 and the first pressure cap 2 meet is the stripping end face of the cable 19 and the sub-cable 20. The way the second pressure cap 6 presses the cable 19 tightly limits the starting point of the lifting of the sub-cable 20 in the subsequent fiber threading process. When the lengths of different sub-cables 20 extending from the end faces of the second pressure cap 6 and the first pressure cap 2 are equal, and the lifting range of the clamping part 10 is the same, the bending range of the sub-cable 20 can be controlled, which makes it convenient for the rubber sleeve 22 to be pushed to the preset position.

[0084] Preferably, one end of the second pressure cap 6 is hinged to the material receiving and fixing component 1, and the other end is detachably assembled with the material receiving and fixing component 1. When it is necessary to fix the cable 19, the second pressure cap 6 is connected and fixed to the material receiving and fixing component 1; when the cable 19 is processed, one end of the second pressure cap 6 is separated from the material receiving and fixing component 1, and the cable 19 can be taken out from the material receiving and fixing component 1. Specifically, the end of the second pressure cap 6 facing the material receiving and fixing component 1 also forms a slot that matches the placement groove 7, and the cooperation between the second pressure cap 6 and the material receiving and fixing component 1 forms a passage for the cable 19 to pass through.

[0085] Furthermore, this application also includes a cap-removing gripper 5, which is disposed on the guide plate 14, and the projection of the cap-removing gripper 5 at least partially coincides with the first cap 2 in a third direction. In this application, the guide plate 14 is a frame structure covering the clamping seat 9, and an opening is provided on the guide plate 14 for the clamping rod 302 to pass through. Simultaneously, the cap-removing gripper 5 is disposed on the guide plate 14, and the driving direction of the cap-removing gripper 5 is vertical. The vertical projection of the cap-removing gripper 5 at least partially coincides with the projection of the first cap 2, allowing the cap-removing gripper 5 to descend and grasp the first cap 2, thereby realizing the removal and placement of the first cap 2. Preferably, the third direction here is the vertical direction.

[0086] Specifically, the cable threading device in this application is used to thread the rubber sleeve 22 into the designated position of the cable 19; the gripper head 1001 of the clamping part 10 is used to clamp the sub-cable 20, and the first drive assembly 11 is used to drive the lifting part to swing to the first position, so that the gripper head 1001 holding the cable 19 and the two clamping rods 302 of the pushing part 3 swing accordingly, so that the part of the sub-cable 20 extending out of the fixed slot forms a first gap with the table surface of the incoming material fixing assembly 1, and the two clamping rods 302 of the pushing part 3 can push the rubber sleeve 22 to the fixed slot through the first gap. Furthermore, the clamping gap between the two clamping rods 302 is greater than the thickness of the sub-cable 20 held by the clamping part 10, and (slightly) less than the thickness of the rubber sleeve 22. This ensures that when the rubber sleeve 22 moves along the extension direction of the sub-cable 20, the two clamping rods 302 can push the rubber sleeve 22 to move without interfering with the sub-cable 20, causing the sub-cable 20 to bend, and without causing excessive friction between the rubber sleeve 22 and the sub-cable 20, making it difficult to push.

[0087] Furthermore, the first drive assembly 11 in this application is used to drive the lifting part to swing between the first position and the second position, and the push part 3 and the clamping part 10 provided on the lifting part also swing accordingly with the swing of the lifting part; at the same time, the material fixing assembly 1 in this application is provided on one side of the lifting part, and it does not swing with the swing of the lifting part. It is mainly used to fix the other end of the cable 19, so that the end of the cable 19 connected to the clamping part 10 can be lifted. At the same time, when the lifting part is in the first position, the straight line formed by the fixing slot and the gripper head 1001 of the clamping part 10 forms a first gap with the material fixing assembly 1; when the lifting part is in the second position, the straight line formed by the fixing slot and the gripper head 1001 of the clamping part 10 forms a second gap with the material fixing assembly 1, and the first gap is greater than the second gap. When the lifting part in this application is in the first position, the second drive assembly 305 pushes the two clamping rods 302 of the pushing part 3, causing the clamping handles 308 of the two clamping rods 302 to move towards the fixed groove along the straight line formed by the fixed groove and the clamping part 10, so as to pass the rubber sleeve 22 to the preset position of the sub-cable 20. Furthermore, the clamping gap between the two clamping rods 302 in this application is greater than the gap between the two gripper heads 1001, so that after the gripper heads 1001 clamp the sub-cable 20, the gap between the clamping handles 308 on the two clamping rods 302 is greater than the thickness of the sub-cable 20, so that the clamping rods 302 can push the rubber sleeve 22 to move.

[0088] Specifically, the first position is the position when the first drive assembly 11 of this application drives the lifting part to swing to the predetermined position, and the second position is the position when the first drive assembly 11 of this application does not drive the lifting part to move, and the clamp 9 on the lifting part is located at the horizontal plane.

[0089] Furthermore, as a preferred embodiment of the present invention, the first pressure cap 2, clamping part 10, and pushing part 3 are arranged in pairs, and the first pressure cap 2, clamping part 10, and pushing part 3 form two independent fiber threading lines. When manufacturing a cable connector, it is necessary to simultaneously set ferrule structures at both ends of the cable connector. To facilitate the synchronous setting of ferrule structures at both ends of the cable 19, the cable threading device in this application includes two sets of paired fiber threading lines, each of which does not interfere with the others. Specifically, this application provides two first pressure caps 2 arranged side-by-side on the incoming material fixing assembly 1. The two first pressure caps 2 are arranged perpendicular to the axial direction of the cable 19. Correspondingly, clamping part 10 and pushing part 3 are arranged in pairs in the extension direction of the cable 19. When it is necessary to simultaneously assemble ferrule structures at both ends of the cable 19, the cable 19 is bent into a U-shape, and both ends of the cable 19 are simultaneously fixed to the first pressure cap 2.

[0090] It is worth noting that in this application, the first coordinate axis of the lifting part coordinate system is the arrangement direction of the lifting part and the material fixing component 1, that is, the arrangement direction of the cable 19; the second coordinate axis of the lifting part coordinate system is the direction in which the clamping part 10 and the lifting part are arranged side by side; the third coordinate axis of the lifting part coordinate system is the vertical direction perpendicular to the table surface of the clamping seat 9. Preferably, when the pushing part 3 and the clamping part 10 of the cable threading device are horizontal and not clamping the cable 19, the first direction is the same as the direction of the first coordinate axis; when the cable threading device is threading the cable, the first direction refers to the direction in which the clamping part 10 points to the opening of the fixing slot after the lifting part swings to the preset position.

[0091] It is worth noting that the aforementioned material fixing assembly 1 is used to place a cable 19 with one end stripped and exposing the sub-cable 20. A first spring 21 and a rubber sleeve 22 are sequentially fitted onto the stripped end of the sub-cable 20. Simultaneously, the pushing part 3 is used to push the first spring 21 and the rubber sleeve 22 to a preset position, so that the rubber sleeve 22 is precisely positioned at the fixing slot. The cable threading device of this invention operates as follows:

[0092] The first pressure cap 2 and the second pressure cap 6 are opened, and the cable 19 is placed into the placement slot 7 on the incoming material fixing assembly 1. The first pressure cap 2 and the second pressure cap 6 are then closed. The third drive assembly 1003 drives the gripper push rod 1002 to move toward the gripper head 1001. The gripper heads 1001 close together to clamp the sub-cable 20. The cap removal gripper 5 moves toward the first pressure cap 2, clamping the first pressure cap 2 and separating it from the incoming material fixing assembly 1. The first drive assembly 11 lifts up, the clamping seat 9 swings as a whole, and the end of the sub-cable 20 lifts up. The air blowing part 4 blows air toward the first spring 21. The second drive assembly 305 drives the push block 303 to move toward the clamping rod 302. The two clamping rods 302 close together, and the two clamping handles 308 clamp the rubber sleeve 22. The second drive assembly 305 drives the rubber sleeve 22 to move toward one end of the first pressure cover 2. When the rubber sleeve 22 reaches the designated position, the two clamping rods 302 return to the initial state. The first drive assembly 11 drives the clamping seat 9 to return to the horizontal state. The cover-removing claw 5 moves downward and presses the first pressure cover 2 onto the material fixing assembly 1. The first pressure cover 2 is adsorbed and fixed on the material fixing assembly 1 and fixes the rubber sleeve 22. The third drive assembly 1003 drives the claw top rod 1002 away from the claw head 1001. The claw head 1001 opens and releases the sub-cable 20.

[0093] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
