A fiber threading device and method

Abstract

This invention discloses a fiber threading device and method, belonging to the field of ferrule manufacturing technology, including the following steps: fixing the parallel-ribbed optical fiber; adjusting the position of the ferrule's insertion window and inserting the parallel-ribbed optical fiber into the guide groove of the ferrule; adjusting the relative position of the ferrule and the parallel-ribbed optical fiber so that the parallel-ribbed optical fiber can be inserted into the insertion channel of the ferrule; applying adhesive through the ferrule's window; threading the parallel-ribbed optical fiber into the insertion channel, so that the end of the parallel-ribbed optical fiber protrudes from the insertion channel away from the insertion window. The fiber threading method of this invention, by adjusting the relative position of the ferrule and the parallel-ribbed optical fiber, makes the parallel-ribbed optical fiber tangent to the guide groove of the ferrule. When pushing the parallel-ribbed optical fiber into the insertion channel, the parallel-ribbed optical fiber slides along the channel of the guide groove into the insertion channel, improving the accuracy of the parallel-ribbed optical fiber entering the insertion channel and significantly reducing the problem of optical fiber damage caused by the parallel-ribbed optical fiber abutting against the ferrule wall.

Description

Technical Field

[0001] This invention belongs to the field of ferrule manufacturing technology, specifically relating to a fiber threading device and a fiber threading method. Background Technology

[0002] Fiber optic patch cords are devices that allow for detachable connections between optical fibers. They are used to precisely align the two ends of an optical fiber to maximize the coupling of light energy from the discovering fiber to the receiving fiber and minimize the impact on the system caused by the connection to the optical link.

[0003] Fiber optic patch cords mainly consist of optical transmission cables and connectors (such as plugs) located at the ends of the cables. During the manufacturing process, operators manually perform rough cutting to ensure the fiber ends are flush. Then, a spring is inserted through the fiber end, and it is then inserted into a rubber plug. After the rubber plug is inserted, the fiber is cut to the desired length, excess fiber ends are removed, and the remaining fiber is stripped. After stripping, any residue on the fiber surface is manually wiped, and the fiber is tested for damage by flicking it with a finger. Finally, the stripped fiber is inserted into a pre-applied MT ferrule.

[0004] Because fiber optic installation requires processes such as coarse cutting, length setting, and fiber stripping, the fiber heights of the fibers in the bundled fiber may be inconsistent. During the insertion of the MT ferrule, the fiber may come into contact with the upper and lower walls of the MT ferrule, leading to installation failure or even fiber breakage. Summary of the Invention

[0005] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a fiber threading device and a fiber threading method to solve the problem that the optical fiber is prone to abutting against the ferrule wall in the existing fiber threading method, causing fiber breakage.

[0006] To achieve the above objectives, the present invention provides a fiber threading method, which includes the following steps:

[0007] S1, fixed and equipped with optical fiber;

[0008] S2. Adjust the position of the ferrule insertion window and insert the end of the parallel fiber into the guide slot of the ferrule;

[0009] S3. Adjust the relative position of the ferrule and the parallel fiber, so that the parallel fiber can be inserted into the corresponding insertion channel of the ferrule.

[0010] S4. Apply the adhesive through the skylight of the insert;

[0011] S5. Insert the parallel fiber into the plug channel, so that the parallel fiber protrudes from the end of the plug channel away from the plug window.

[0012] As a further improvement of the present invention, S2 specifically includes:

[0013] S201. Adjust the position of the ferrule or the parallel fiber along the third direction so that the parallel fiber is located between the top surface of the insertion window and the platform of the guide groove.

[0014] S202, Move along the first direction with optical fiber and insert the optical fiber into the platform of the guide groove.

[0015] As a further improvement of the present invention, after step S202, the method further includes: moving along the second direction with an optical fiber or ferrule, such that the projection of the optical fiber along the first direction falls on the area where the guide groove is located.

[0016] As a further improvement of the present invention, S3 specifically includes:

[0017] S301, Move the ferrule along the third direction so that the fiber optic cable contacts the platform of the guide slot;

[0018] S302. The ferrule is swung around the second direction as an axis so that each fiber in the parallel fiber contacts the platform of the guide slot.

[0019] S303, Move the ferrule a second time along the third direction so that there is a gap between the end of the fiber facing the insertion channel and the bottom surface of the guide groove.

[0020] As a further improvement of the present invention, the ferrule swing angle range is 5°~10°.

[0021] As a further improvement of the present invention, S3 also includes:

[0022] S304. Move along the first direction with optical fiber and insert the optical fiber into the plug-in channel.

[0023] S305. If the parallel fiber can be inserted into the corresponding insertion channel, move the parallel fiber in the direction away from the insertion channel so that the parallel fiber returns to the original position of the guide groove.

[0024] If the parallel fiber cannot be inserted into the plug channel, adjust the position of the ferrule until the parallel fiber can be inserted into the plug channel, and move the parallel fiber to the original position of the guide slot.

[0025] As a further improvement of the present invention, in S5, the optical fiber moves back and forth multiple times along the first direction between the original position of the guide groove and one end of the insertion channel guide groove.

[0026] As a further improvement to the present invention, S6 is also included:

[0027] S601, the ferrule swings along a third direction, so that the ferrule is arranged horizontally as a whole;

[0028] S602, Move the ferrule along the third direction so that the parallel fiber extends horizontally along the first direction;

[0029] S603, Move along the first direction and carry the optical fiber, so that the rubber plug on the optical fiber passes into the insertion channel.

[0030] As a further improvement of the present invention, it also includes S7: grinding one end of the fiber extending from the insertion channel so that the fiber end is not wrapped with glue.

[0031] This application also includes a fiber threading device, which comprises:

[0032] A first clamping member and a second clamping member, wherein the clamping opening of the first clamping member and the clamping opening of the second clamping member at least partially overlap along a first direction;

[0033] A first displacement mechanism, wherein the first clamping member is connected to the first displacement mechanism, and the first displacement mechanism is used to drive the first clamping member to move along a first direction and a second direction;

[0034] The second displacement mechanism is connected to the second clamping member, and the second displacement mechanism is used to drive the second clamping member to move and swing in a third direction.

[0035] As a further improvement of the present invention, the second displacement mechanism includes a first moving component, the first moving component including a base, a sliding part and a pushing part;

[0036] The base has an arc-shaped groove, the bottom surface of the sliding part is an arc-shaped convex surface, the sliding part is slidably disposed on the base, the pushing part abuts against the sliding part, and the pushing shaft of the pushing part extends along the first direction.

[0037] As a further improvement of the present invention, it also includes an identification mechanism and a dispensing mechanism, both of which are disposed above the first clamping member, and the relative positions of the identification mechanism, the dispensing mechanism and the first clamping member along the second direction are adjustable.

[0038] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0039] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include:

[0040] (1) The fiber threading method of the present invention adjusts the relative position of the ferrule and the parallel fiber, and limits and presses the parallel fiber through the guide groove of the ferrule, so that the parallel fiber is flush as a whole, avoiding the problem of some fibers in the parallel fiber lifting and abutting against the wall of the ferrule, causing damage to the fiber.

[0041] (2) The fiber threading method of the present invention adjusts the vertical position of the ferrule and the parallel fiber once, so that the parallel fiber is pressed into the guide groove. Then, the ferrule is driven to swing, and the parallel fiber tends to be bent by the ferrule, so that the raised fiber and the other fibers in the parallel fiber fall on the bottom surface of the guide groove. Finally, by lifting the ferrule, the end of the parallel fiber is tangent to the guide groove. When the parallel fiber is pushed into the insertion channel, the parallel fiber slides into the insertion channel along the channel of the guide groove, thereby improving the accuracy of the parallel fiber entering the insertion channel.

[0042] (3) The fiber threading method of the present invention determines the matching degree between the fiber and the plug channel by trial threading, then puts the glue in from the skylight, and then uses the fiber to bring the glue into the plug channel by repeated fiber threading, so that the plug channel is filled with glue and free of air bubbles, ensuring the optical transmission performance of the finished fiber patch cord.

[0043] (4) The fiber threading device of the present invention, through the combined use of the first displacement mechanism and the second displacement mechanism, realizes the threading of the fiber and the ferrule, the automatic adjustment of the ferrule position, etc., and realizes a similar method to manual threading in a device manner. Moreover, the threading method of the fiber threading device can realize the overall accuracy of fiber threading, make up for the difference problem in the manual fiber threading process, ensure the quality of fiber threading, and improve the overall yield of fiber optic patch cords.

[0065] Example:

[0066] Please see Figures 1-11 In a preferred embodiment of the present invention, the fiber threading device includes a first clamping member 3 and a second clamping member 4, wherein the clamping opening of the first clamping member 3 and the clamping opening of the second clamping member 4 at least partially overlap along a first direction; the first clamping member 3 is connected to a first displacement mechanism 5, which is used to drive the first clamping member 3 to move along a first direction and a second direction; the second clamping member 4 is connected to a second displacement mechanism 7, which is used to drive the second clamping member 4 to swing about the second direction as an axis and move along a third direction.

[0067] The first clamping member 3 in this application is mainly used to clamp the parallel-ribbed optical fiber 1, and the second clamping member 4 in this application is mainly used to clamp the ferrule 2. The first displacement mechanism 5 and the second displacement mechanism 7 work together to move the parallel-ribbed optical fiber 1 and the ferrule 2, thereby achieving the insertion of the parallel-ribbed optical fiber 1 and the ferrule 2. It should be noted that the parallel-ribbed optical fiber 1 is formed by removing the outer sheath of the optical fiber, arranging the optical fibers sequentially to form a ribbon-like structure, and fixing the optical fibers with glue or tape.

[0068] Preferably, the first direction in this application is the direction in which the first clamping member 3 and the second clamping member 4 are arranged opposite each other, the second direction is preferably the direction perpendicular to the first direction in the horizontal direction, and the third direction is preferably the vertical direction.

[0069] Specifically, the first clamping member 3 in this application is preferably a jig, which can fix the parallel fiber 1. Simultaneously, the end of the parallel fiber 1 that passes through the ferrule 2 is essentially flush. It should be noted that the first clamping member 3 can also fix the rubber plug and spring that pass through the parallel fiber 1. The parallel fiber protrudes from the first clamping member on the side of the rubber plug facing away from the spring. This protruding fiber has a bare core structure (fiber with the surface coating removed). During the insertion of the parallel fiber 1 into the ferrule 2, the section inserted into the ferrule is the parallel fiber connected to the rubber plug on the side facing away from the spring. Without special explanation, the later mention of inserting the parallel fiber into the ferrule 2 actually refers to the parallel fiber with a bare core structure connected to the rubber plug on the side facing away from the spring. During the insertion of the parallel fiber into the ferrule 2, the rubber plug and spring are fixed within the first clamping member and move with it.

[0070] The first displacement mechanism 5 in this application includes a platform on which the first clamping member 3 is fixedly mounted, and a first driving mechanism is provided below the platform. The first driving mechanism is used to drive the entire platform to move along a first direction so as to insert the parallel fiber 1 into the ferrule 2. A second driving mechanism is provided below the first driving mechanism and is mounted on a slide rail 6 extending along a second direction. The second driving mechanism can drive the entire platform to move along the second direction so as to align the parallel fiber 1 in the port of the ferrule 2.

[0071] Furthermore, the second clamping member 4 in this application preferably includes a clamping body, the upper end of which is provided with two clamping blocks arranged opposite each other along a second direction, wherein the clamping blocks can move along the second direction to realize the change of the clamping gap between the two clamping blocks, thereby realizing the clamping and fixing of the insert 2. Correspondingly, a second displacement mechanism is provided below the clamping body, the second displacement mechanism specifically including a first moving component 701 and a second moving component 702, wherein the first moving component 701 is a slide structure, the bottom surface of which is arc-shaped, and the slide can drive the second clamping member 4 to swing about the second direction as an axis. Specifically, the first moving component 701 in this application includes a base 7011, a sliding part 7012, and a pushing part 7013. The base 7011 has an arc-shaped groove, and the bottom surface of the sliding part 7012 has a corresponding arc-shaped convex surface. The sliding part 7012 is slidably disposed on the base 7011, while the pushing part 7013 abuts against the sliding part 7012. The pushing shaft of the pushing part 7013 extends along a first direction. When the first moving component 701 needs to drive the second clamping member 4 to swing, the pushing part 7013 drives the sliding part 7012 to swing within the arc-shaped groove. The ferrule 2 held by the second clamping member 4 swings accordingly, and the insertion channel 203 end of the ferrule 2 is higher than the insertion window 201 end, causing the ferrule 2 to tilt as a whole. The side of the ferrule 2 away from and carrying the optical fiber 1 is higher along a third direction than the side of the ferrule 2 closer to and carrying the optical fiber 1.

[0072] As an optional embodiment of the present invention, the first moving component 701 in this application includes a lifting part, which is disposed on the side of the second clamping member 4 away from the first clamping member 3 along the first direction. When the lifting part correspondingly lifts the second clamping member 4, the side of the ferrule 2 that is away from and carries the optical fiber 1 is higher than the side of the ferrule 2 that is close to and carries the optical fiber 1 along the third direction, and the ferrule 2 is in an inclined state.

[0073] Correspondingly, the second moving component 702 is located below the first moving component 701, and is used to drive the second clamping member 4 to move up and down along a third direction.

[0074] The ferrule 2 in this application specifically includes a ferrule 2 body. The ferrule 2 body has a insertion window 201, a guide groove 202, and an insertion channel 203 sequentially formed along a first direction. The insertion window 201, the guide groove 202, and the insertion channel 203 penetrate the ferrule 2 body along the first direction. The insertion window 201 is a rectangular area. The guide groove 202 is a plurality of arcs (grooves with an arc-shaped cross-section), and the radius of the arc is slightly larger than the radius of each optical fiber. There is a stepped surface between the guide groove 202 and the insertion window 201, and the height of the guide groove 202 along a third direction is higher than the height of the lower surface of the insertion window. The insertion channel 203 is a plurality of parallel circular holes, and the diameter of the circular holes is slightly larger than the diameter of each optical fiber. The circular holes are concentric with the arcs. In one specific embodiment, the side of the insertion channel 203 near the guide groove 202 has a flared opening for introducing optical fibers. Meanwhile, the insertion window 201 and the guide groove 202 are provided with a skylight 204 on one side along the third direction. The skylight 204 partially connects the insertion window 201 and the guide groove 202. The installation of the parallel fiber 1 in the ferrule 2 can be viewed through the skylight 204, and adhesive dots can be applied into the ferrule 2 through the skylight 204.

[0075] Specifically, as a preferred embodiment of the present invention, the fiber threading device in this application further includes an adhesive dispensing component 8 and an identification component 9, wherein the adhesive dispensing component 8 and the identification component 9 are both disposed above the second clamping member 4, and both the adhesive dispensing component 8 and the identification component 9 have a driving mechanism for moving along a second direction. The driving mechanism drives the adhesive dispensing component 8 and the identification component 9 to move. When the identification component 9 is located above the skylight 204, the position and status of the fiber 1 can be observed through the skylight 204. When the adhesive dispensing component 8 is located above the skylight 204, adhesive can be dispensed through the skylight 204 to insert the adhesive into the ferrule 2. Specifically, the adhesive dispensing point is located in the guide groove 202 area.

[0076] Based on the fiber threading device in this application, this application also includes a fiber threading method, which specifically includes the following steps:

[0077] S1. Fixing the parallel fiber 1; In this application, the fixing of the parallel fiber 1 is mainly achieved by the first clamping member 3, which is mainly to ensure the stability of the parallel fiber 1 during the insertion process. In addition, the end of the parallel fiber 1 that is inserted into the ferrule 2 in this application has been wiped clean, and the coating layer on its surface has been removed.

[0078] S2. Adjust the position of the insertion window 201 of the ferrule 2 and insert the parallel fiber 1 into the guide groove 202 of the ferrule 2.

[0079] S3. Adjust the relative positions of the ferrule 2 and the parallel fiber 1 so that the parallel fiber 1 can be inserted into the insertion channel 203 of the ferrule 2. Optionally, during the adjustment process, in addition to adjusting the position of the ferrule 2, the position of the parallel fiber 1 can also be adjusted, or the parallel fiber 1 and the ferrule 2 can be adjusted at the same time.

[0080] S4. Apply the adhesive through the skylight 204 of the insert 2;

[0081] S5. Insert the parallel fiber 1 into the plug channel 203, so that the parallel fiber 1 protrudes from the end of the plug channel 203 away from the plug window 201.

[0082] Furthermore, step S2 in this application specifically includes:

[0083] S201. Adjust the position of the ferrule 2 or the fiber 1 along the third direction so that the fiber 1 is located between the top surface of the insertion window 201 and the platform of the guide groove 202.

[0084] S202, Move along the first direction and carry optical fiber 1, so that the projection of optical fiber 1 on the ferrule 2 is located on the guide groove 202.

[0085] The fiber threading process in this application is achieved through a fiber threading device. Specifically, in one embodiment, since the size of the ferrule 2 is fixed and the diameter of the optical fiber also has a unified standard, the initial position height of the first clamping member 3 and the second clamping member 4 can be set so that the height of the parallel fiber 1 along the third direction is higher than the height of the guide groove 202 and lower than the height of the inner wall of the insertion window. This ensures that when the parallel fiber 1 is inserted into the ferrule 2, it will not abut against the step formed by the guide groove 202 and the insertion window 201, nor will it abut against the inner wall of the insertion window. Thus, when the parallel fiber 1 is inserted along the first direction, it is positioned above the platform of the guide groove 202 along the third direction. This application uses the first moving component 701 to adjust the height of the ferrule 2 in the third direction, so that the parallel fiber 1 can be inserted into the ferrule 2 accordingly. As a further improvement to this solution, the initial positions of the first clamping member 3 and the second clamping member 4 can be achieved through electrical control. That is, the initial positions of the first clamping member 3 and the second clamping member 4 can be set by the first displacement mechanism 5 and the second displacement mechanism 7. When other specifications of fiber optic cables or ferrules are replaced, the initial positions of the first clamping member 3 and the second clamping member 4 can be changed so that after the material is replaced, the height of the fiber optic cable along the third direction is higher than the height of the ferrule guide groove and lower than the height of the inner wall of the insertion window.

[0086] In another embodiment of the present invention, the height of the top surface of the insertion window 201 along the third direction and the height of the platform of the guide groove 202 are visually recognized. Specifically, by obtaining the height of the top surface of the insertion window 201 along the third direction and the height of the platform of the guide groove 202, the height of the parallel fiber 1 when it is inserted is obtained. By adjusting the position of the parallel fiber 1 along the third direction accordingly, the height of the parallel fiber 1 along the third direction is higher than the height of the guide groove 202 and lower than the height of the inner wall of the ferrule 2. This ensures that when the parallel fiber 1 is inserted into the ferrule 2, it will not abut against the step formed by the guide groove 202 and the insertion window 201, nor will it abut against the inner wall of the insertion window. Thus, when the parallel fiber 1 is inserted along the first direction, it is located above the platform of the guide groove 202 along the third direction.

[0087] Preferably, after adjusting the height of the ferrule 2 or the parallel fiber 1 along a third direction in step S201 of this application, it further includes: moving the parallel fiber 1 or the ferrule 2 along a second direction, so that the projection of the parallel fiber 1 falls on the area where the guide groove 202 is located, and each fiber in the parallel fiber 1 falls into the conductor groove 202. During the insertion process, since the parallel fiber 1 extends a certain length along the second direction, it is also necessary to adjust the position of the parallel fiber 1 or the ferrule 2 in the second direction accordingly, so that the parallel fiber 1 does not abut against the two side walls of the insertion window 201, and does not abut against the inner wall of the insertion channel 203 during the insertion process. It should be noted that the parallel fiber 1 contains multiple fibers. When adjusting the parallel fiber 1 to fall into the guide groove 202, each arc of the guide groove 202 accommodates each fiber in the parallel fiber 1. Here, since the radius of the guide groove 202 matches the radius of the fiber, and the parallel fiber 1 itself is initially fixed with glue, there will be no situation where one arc accommodates two fibers.

[0088] Furthermore, as a preferred embodiment of the present invention, step S3 in this application specifically includes:

[0089] S301, Move the ferrule 2 along the third direction so that the fiber 1 with parallel cable comes into contact with the platform of the guide slot 202;

[0090] S302, the ferrule 2 is swung along the third direction so that each fiber in the parallel fiber 1 is in contact with the platform of the guide groove 202;

[0091] Preferably, in step S302 of this application, the swing angle of the ferrule 2 is between 5° and 10°. In the normal placement state, the ferrule 2 is placed horizontally on the plane. When the ferrule 2 is swung in step S302, the first moving component 701 drives the ferrule 2 to swing, causing one end of the insertion channel 203 of the ferrule 2 to rise, and the angle between the ferrule 2 as a whole and the horizontal plane is between 5° and 10°.

[0092] It is worth noting that the swing amplitude of the ferrule 2 in this application is small. During the swing, the parallel fiber 1 and the ferrule 2 undergo a slight displacement along the first direction. This displacement will not cause the parallel fiber 1 to detach from the guide groove 202. Optionally, in order to ensure that the parallel fiber 1 does not detach from the guide groove 202, the parallel fiber 1 can be moved a set distance along the first direction toward the ferrule 2 after S302 to ensure that the parallel fiber 1 always falls on the guide groove 202.

[0093] S303, the ferrule 2 is moved a second time along the third direction, so that the end of the fiber 1 facing the insertion channel 203 leaves a gap with the bottom surface of the guide groove 202.

[0094] Specifically, this application first raises the ferrule 2 along a third direction in step S301, so that all the parallel fiber 1 falls into the guide groove 202 and connects with the bottom surface of the guide groove 202, so that the parallel fiber 1 can pass into the insertion channel 203 in the subsequent process. At the same time, in step S302, the ferrule 2 is swung so that the parallel fiber 1 and the guide groove 202 form a certain angle. During this process, some of the straight fibers will abut against the platform of the guide groove 202 and be raised accordingly. At this time, some of the raised fibers and the straight fibers are raised to the same height, so that each fiber core in the parallel fiber 1 abuts against the platform of the guide groove 202. Then, in step S303, the ferrule 2 is raised a second time, so that the parallel fiber 1 bends, and finally presents a form similar to bending and cutting into the guide groove 202 (e.g., Figure 9 As shown in the figure, its end has a gap with the bottom surface of the guide groove 202, which facilitates the subsequent insertion of the optical fiber 1 into the plug-in channel 203.

[0095] More preferably, this application also includes step S304: moving along the first direction with the optical fiber 1 and inserting the optical fiber 1 into the insertion channel 203;

[0096] S305. If the parallel fiber 1 can be inserted into the insertion channel 203, move the parallel fiber 1 in the direction away from the insertion channel 203 so that the parallel fiber 1 returns to the original position of the guide groove 202.

[0097] If the parallel fiber 1 cannot be inserted into the insertion channel 203, adjust the position of the ferrule 2 until the parallel fiber 1 can be inserted into the insertion channel 203, and move the parallel fiber 1 to the original position of the guide groove 202. After the position adjustment of the parallel fiber 1 and the ferrule 2 is completed in the above steps S301~S303, it does not mean that the parallel fiber 1 can be inserted into the insertion channel 203. Since the fixed position of the parallel fiber 1 with glue or tape is a certain distance from the end face of the fiber, and the process of stripping and wiping the fiber before inserting the parallel fiber 1 into the ferrule 2 will cause the height of the multiple fibers on the end face of the parallel fiber 1 to be inconsistent in the third direction. Therefore, the distance between the end of the parallel fiber 1 and the surface of the guide groove 202 may be different in each fiber insertion process. Therefore, it is necessary to perform trial insertion of the parallel fiber 1 as in steps S304 and S305 of this application to ensure that the parallel fiber 1 can be inserted into the insertion channel 203. Correspondingly, when the parallel fiber 1 cannot be inserted, the relative position of the parallel fiber 1 and the ferrule 2 needs to be adjusted to ensure that the parallel fiber 1 is inserted into the insertion channel 203.

[0098] Furthermore, in step S5 of this application, the optical fiber 1 is moved back and forth multiple times along the first direction. During the dispensing process, adhesive is also needed to fix the optical fiber in the insertion channel 203. The adhesive dispensed into the skylight 204 is mainly carried into the insertion channel 203 through the optical fiber. In order to ensure that the insertion channel 203 is completely filled with adhesive and to avoid the formation of air bubbles inside, which would affect the optical performance of the optical fiber patch cord, this application involves repeatedly passing the fiber along the first direction to ensure that the insertion channel 203 is filled with adhesive.

[0099] Furthermore, the fiber threading method in this application also includes step S6:

[0100] S601, Swing the ferrule 2 along the third direction so that the ferrule 2 is arranged horizontally as a whole;

[0101] S602, Move the ferrule 2 along the third direction so that the parallel fiber 1 extends horizontally along the first direction;

[0102] S603, Move along the first direction and carry optical fiber 1, so that the rubber plug on optical fiber 1 is inserted into the insertion channel 203.

[0103] After inserting the parallel fiber 1 into the insertion channel 203, the corresponding rubber plug carried on the parallel fiber 1 also needs to be inserted into the insertion window 201 of the ferrule 2. Since the size of the rubber plug is similar to that of the insertion window 201, if the parallel fiber 1 and the ferrule 2 are set at an angle to each other, the rubber plug will not be able to be inserted into the ferrule 2. Based on this, this application swings the ferrule 2 to restore it to a horizontal state, and then moves the ferrule 2 downward along a third direction so that the parallel fiber 1 is inserted into the ferrule 2 in a straight state. At this time, the parallel fiber 1 is basically in a horizontally extending state along the first direction.

[0104] Preferably, this application further includes step S7: grinding one end of the fiber optic cable 1 extending out of the plug-in channel 203 so that the end of the fiber optic cable 1 is free of adhesive wrapping. Correspondingly, the fiber optic patch cord in this application is used for the connection and transmission of optical signals. At this time, it is necessary to grind the end of the fiber optic cable 1 so that all the adhesive on the end of the fiber optic cable 1 extending out of the plug-in channel 203 is removed, so as to realize the optical signal transmission between the optical fibers.

[0105] Specifically, the fiber threading device in this application performs the following steps for fiber threading:

[0106] The first clamping member 3 and the second clamping member 4 are used to clamp and fix the fiber optic cable 1 and the ferrule 2 respectively. The positions of the first clamping member 3 and the second clamping member 4 are initialized so that the fiber optic cable 1 is located between the top surface of the insertion window 201 and the bottom surface of the guide groove 202 in the third direction to facilitate subsequent insertion. The second driving mechanism moves along the slide rail 6 so that the fiber optic cable 1 is aligned with the guide groove 202 in the first direction. The first driving mechanism drives the fiber optic cable 1 to move towards the ferrule 2 and the fiber optic cable 1 falls into the channel where the guide groove 202 is located. The second moving component 702 moves along... The ferrule 2 is vertically raised, with the fiber optic cable 1 abutting against the bottom surface of the guide groove 202; the first moving component 701 swings accordingly, causing the end of the ferrule 2 away from the fiber optic cable 1 to tilt upwards, and the fiber optic cable 1 to connect with the guide groove 202 at an angle; the second moving component 702 raises the ferrule 2 a second time, and the fiber optic cable 1 is slightly bent and tangent to the guide groove 202; the first driving mechanism drives the fiber optic cable 1 to move towards the insertion channel 203, and the fiber optic cable 1 is inserted into the insertion channel 203 accordingly; the first driving mechanism drives the fiber optic cable 1 to move in the direction away from the ferrule 2, and The fiber optic cable 1 returns to the guide groove 202; the dispensing assembly 8 moves above the skylight 204 of the ferrule 2, dispensing adhesive and wrapping the end with the fiber optic cable 1; the fiber optic cable 1 is reciprocated into the insertion channel 203 along the first direction, and adhesive tape is inserted into the insertion channel 203, filling the insertion channel 203 with adhesive; the first drive mechanism drives the fiber optic cable 1 to extend from the other end of the insertion channel 203; the first moving assembly 701 drives the ferrule 2 to swing, the end of the ferrule 2 away from the end with the fiber optic cable 1 descends, and the ferrule 2 is arranged horizontally; the second moving assembly 701 drives the ferrule 2 to swing, the end of the ferrule 2 away from the end with the fiber optic cable 1 descends, and the ferrule 2 is arranged horizontally as a whole .... Component 702 drives the ferrule 2 to descend, and the fiber 1 is in a straight state. The first drive mechanism drives the fiber 1 to move toward the ferrule 2, and the rubber plug on the fiber 1 is inserted into the insertion window 201 of the ferrule 2. The second clamping component releases the ferrule 2, and the first drive mechanism drives the fiber 1 to move away from the second clamping member 4. The ferrule 2 is inserted onto the fiber 1 and is correspondingly pulled away from the second clamping member 4, and the fiber insertion is completed. Subsequently, the end of the fiber 1 extending out of the insertion channel 203 is polished so that the end of the fiber 1 is not wrapped with glue.

[0107] As a further improvement to this solution, the position of the insertion window 201 of the ferrule 2 can also be obtained through visual recognition, and the positions of the top surface of the insertion window 201 and the bottom surface of the guide groove 202 along the third direction can be obtained; the second moving component 702 moves up and down along the third direction, so that the parallel fiber 1 is located between the top surface of the insertion window 201 and the bottom surface of the guide groove 202 in the third direction.
