To solve at least one aspect of the problems in the background art, the present invention provides an automatic fiber stripping device, which may be referred to as a "full-automatic fiber connector batch fiber stripping device", and in the embodiments described below, includes a device capable of performing batch fiber stripping.

Fig. 1 is a perspective view showing an embodiment of the automatic fiber stripping device. It is understood that the optical fiber line described herein refers to a wire material before the optical fiber patch cord is connected to the splice (ferrule), and includes an optical fiber line core and a protective layer covering the optical fiber line core.

The automatic fiber stripping device comprises a frame 1. Conventionally, the frame 1 is an assembly of aluminium profiles and plates, the structural arrangement of which is well known to those skilled in the art and will not be described in detail here and not illustrated in its entirety in the figures.

An optical fiber line carrier (optical fiber carrier) 2 is arranged on the rack 1, the optical fiber line carrier 2 is movable in the rack 1, if the optical fiber line carrier can be installed along the rack 1 in a transverse sliding manner, and an optical fiber line clamp (optical fiber clamp) 22 is fixedly arranged on the optical fiber line carrier 2. The optical fiber carrier 2 is placed with the optical fiber 23 to be stripped, as shown in the embodiment of the figure, the optical fiber carrier 2 is provided with an optical fiber placing basket 21, and the optical fiber is carried and placed in the optical fiber placing basket 21. The optical fiber wire clamp 22 fixed on the optical fiber wire carrier 2 can primarily fix the end of the optical fiber wire 23 which needs to be stripped. If the optical fiber line clamp 22 is two plate members for arranging and clamping a plurality of optical fiber lines, the optical fiber line clamp 22 can clamp and fix the optical fiber lines by using a conventional fixing device in the art, which is well known to those skilled in the art and will not be described herein again.

The transmission driving assembly 3 (transmission driving device) is disposed between the optical fiber carrier 2 and the rack 1, and can drive the optical fiber carrier 2 to move on the rack 1. The rack 1 is provided with a plurality of different stations, such as a fiber stripping station and a cleaning station, which are described in detail later, and when the optical fiber carrier 2 is driven by the transmission driving component 3, the optical fiber carrier can move from one station to another station on the rack. Specifically, the transmission driving assembly 3 includes two transmission pulleys 31 rotatably mounted on the frame 1, a double-sided toothed belt 32 is disposed between the two transmission pulleys 31, a transmission toothed plate 34 capable of meshing with the double-sided toothed belt 32 is disposed on the optical fiber carrier 2, and a transmission driving motor 33 is connected to one of the transmission pulleys 31. After the transmission driving motor 33 drives the double-sided toothed belt 32 to move, the transmission toothed plate 34 drives the optical fiber carrier 2 to generate transverse displacement due to the meshing effect, so that transmission driving is realized. Meanwhile, in the parts not shown in the figure, one of the rack 1 and the optical fiber line carrier 2 has a slide rail, and the other has a slide groove, and the optical fiber line carrier 2 and the rack 1 are connected in a sliding fit manner through the slide rail and the slide groove.

Fig. 2 shows a schematic three-dimensional enlarged structure of the fiber stripping station of the automatic fiber stripping device, the rack 1 is further provided with an optical fiber wire guiding and clamping assembly (optical fiber guiding and clamping device) 4, and the position of the optical fiber wire guiding and clamping assembly 4 is the fiber stripping station of the rack 1. At the fiber stripping station of the frame 1, the optical fiber wire guiding and clamping component 4 is arranged below the optical fiber wire clamp 22, when the transmission driving component 3 drives the optical fiber wire carrier 2 to the fiber stripping station, the optical fiber wire guiding and clamping component 4 can guide and fix the optical fiber wire 23 clamped on the optical fiber wire clamp 22, so that the optical fiber wire 23 can freely hang down due to the guiding and self-weight effects. The direction in which the optical fiber wire hangs freely due to the guiding and self-weight action is the extending direction a of the optical fiber wire. After the suspended optical fiber wire 23 is clamped by the optical fiber wire guiding and clamping assembly 4, a short section is formed below the optical fiber wire guiding and clamping assembly 4, so that a straight vertical state can be easily formed, and the stability and the accuracy of the subsequent fiber stripping operation can be ensured.

The specific structure of the optical fiber wire guiding and clamping assembly 4 is shown in fig. 3, the optical fiber wire clamping assembly 4 includes a first clamping unit 41 and a second clamping unit 42, and the first clamping unit 41 and the second clamping unit 42 can move relatively to each other to approach each other until moving to a clamping position where the optical fiber wire to be clamped can be clamped.

The first clamping unit 41 has a plurality of first slots 410 and a plurality of first teeth 411 as shown in the drawing, and the first teeth 411 and the first slots 410 are respectively disposed at different positions in the extending direction a of the optical fiber, that is, the first teeth 411 and the first slots 410 are staggered with each other along the extending direction a of the optical fiber, and may be disposed adjacently as shown in the drawing, or may be disposed at intervals with each other different from the one shown in the drawing.

The plurality of first teeth 411 and the plurality of first slots 410 are respectively arranged along the length direction b of the first clamping unit 41, and the first slots 410 protrude from the first teeth 411 toward the fiber optic cable position as shown in the figure. The optical fiber line position refers to the position of a plurality of optical fiber lines to be clamped. The tooth top of the first tooth 411 is aligned with the groove bottom of the first groove 410 in the fiber-line extending direction a, i.e., the tooth top of the first tooth 411 is one-to-one opposed to the groove bottom of the first groove 410 in an orthographic projection viewed in a top view in the holding unit as shown in the drawing. Since the optical fiber to be held is drooping in the extending direction a of the optical fiber, the optical fiber at the bottom of the first groove 410 is located at the tooth top of the first tooth 411.

The second clamping unit 42 is disposed opposite to the first clamping unit 41 as shown in the figure, and includes a plurality of second slots 420, and the plurality of second slots 420 and the plurality of first teeth 411 are disposed correspondingly. And for the corresponding first tooth 411 and second slot, the inner profile of the second slot 420 is conformal and aligned with the outer profile of the first tooth 411 as shown in the figure, so that in the clamped state, the second slot 420 can cooperate with the first tooth 411 to clamp the optical fiber line, i.e. the tooth top of the first tooth 411 can clamp the optical fiber line to the groove bottom of the second slot 420.

During clamping, the plurality of optical fiber wires to be clamped are suspended, and the first clamping unit 41 and the second clamping unit 42 move relative to each other. Ideally, a plurality of optical fiber wires to be clamped hang down in a direction perpendicular to the horizontal plane, the positions of the optical fiber wires are just located at the middle position between the tooth tops of the first teeth 411 and the groove bottoms of the second grooves 420, and the first clamping unit 41 and the second clamping unit 42 move relative to each other at the same constant speed at the same time.

However, in actual conditions, although the optical fiber wire to be clamped is in a substantially suspended state, since the optical fiber wire is a flexible member, slight deformation or bending may occur, so that the optical fiber wire may be warped toward the first clamping unit 41 or the second clamping unit 42. Or the overhanging position of the optical fiber line may be slightly closer to the first clamping unit 41 or the second clamping unit 42. In a case that may occur in any of the aforementioned practical conditions, when the first clamping unit 41 and the second clamping unit 42 are moved relative to each other, the first clamping unit 41 may come into contact with the optical fiber line to be clamped before the second clamping unit 42. At this time, if the first slot 410 is not provided in the first holding unit 41, it may occur that the optical fiber wire slides along the tooth wall of the first tooth 411, causing the optical fiber wire to be pinched between the tooth wall of the first tooth 411 and the slot wall of the second slot 420. By arranging the first groove 410 in the first clamping unit 41, when the optical fiber to be clamped is relatively closer to the first clamping unit 41, the first clamping unit 41 at this time contacts with the optical fiber, the first groove 410 at this time contains the optical fiber to be clamped therein first, and plays a certain guiding role for the optical fiber in the process of gradually approaching to the second clamping unit 42, so that the optical fiber gradually falls into the bottom of the first groove 410 and is just positioned at the top of the first tooth 411, and thus in the clamping state, the top of the first tooth 411 clamps the optical fiber at the bottom of the second groove 420. Similarly, if the optical fiber to be clamped is relatively closer to the second clamping unit 42, the second clamping unit 42 will contact the optical fiber first, and the second groove 20 will contain the optical fiber to be clamped therein first, and will guide the optical fiber in the process of gradually approaching to the second clamping unit 41, so that the optical fiber gradually falls into the bottom of the second groove 420, and thus the tooth crest of the first tooth 411 will clamp the optical fiber to the bottom of the second groove 420 in the clamped state.

As described above, no matter whether the optical fiber to be clamped is closer to the first clamping unit 41 or the second clamping unit 42 or both of them are in contact with the optical fiber, it can be ensured that the optical fiber is clamped between the tooth top of the first tooth 411 and the groove bottom of the second groove 420 in the clamped state, and it is ensured that the optical fiber does not fall between the tooth wall of the first tooth 411 and the second groove 420, so that the optical fiber can be clamped at a desired position, and the optical fiber can be further processed in the subsequent process.

The first clamping unit 41 and the second clamping unit 42 may be driven by an air cylinder 45 shown in the figure to move relatively or oppositely, specifically, the first clamping unit 41 and the second clamping unit 42 may also be slidably disposed on a frame body, and are driven by the air cylinder 45 to slide, which is not described herein again.

The rack 1 is also provided with a fiber tail processing assembly, the fiber tail processing assembly is used for carrying out coating stripping, clamping and cutting procedures on the fiber tail of the optical fiber line, and the fiber tail refers to a section of one end of the optical fiber line, which needs to be stripped. Fig. 4 is a perspective view of an embodiment of the fiber tail processing assembly, and fig. 5 is an exploded view of an embodiment of the fiber tail processing assembly. Fig. 6 and 8 are schematic views showing the tail processing assembly in an initial state according to one embodiment, fig. 7 and 9 are schematic views showing the tail processing assembly in a state of clamping a position of an optical fiber wire according to one embodiment, fig. 10 is an enlarged view of a portion a of fig. 9, and fig. 11 is a schematic view showing a state when the optical fiber wire is stripped or after a fiber stripping operation is completed according to one embodiment.

The fiber tail processing assembly comprises a fiber stripping frame 5, and a fiber tail cutting device 6 and a hot melting separation device 7 which are arranged on the fiber stripping frame 5. The fiber tail cutting device 6 is used for uniformly cutting the bottom ends of the optical fiber wires 23 after the optical fiber guiding and clamping device 4 guides and clamps the optical fiber wires 23. The fiber tail cutting device 6 comprises two fiber tail cutting seats 61 which are arranged on the fiber stripping frame 5 in a relatively sliding mode, cutting blades 63 are fixedly arranged on the two fiber tail cutting seats 61 respectively, and fiber tail cutting drivers 62 are arranged between the two fiber tail cutting seats 61 and the fiber stripping frame 5 respectively. When the fiber tail cutting driver 62 drives the two fiber tail cutting seats 61 to approach each other, the shearing force of the two cutting blades 63 can form a cutting effect on the bottom ends of the plurality of optical fiber wires 23, and after cutting, the lengths of the plurality of optical fiber wires 23 below the optical fiber guiding and clamping device 4 form the same length.

The hot melting separation device 7 is used for hot melting the upper end of the coating layer to be stripped of the optical fiber 23, the hot melting separation device 7 comprises two hot melting separation seats 70 which are arranged on the fiber stripping frame 5 in a relatively sliding mode, coating layer clamping parts 71 are respectively fixedly arranged on the two hot melting separation seats 70, and coating layer cutting blades 72 are respectively fixedly arranged on the hot melting separation seats 70 above the coating layer clamping parts 71. A hot melting separation driver is respectively arranged between the two hot melting separation seats 70 and the fiber stripping frame 5. The hot melt heating apparatus further includes a hot melt heating unit (hot melt heating rod) 74 provided on the hot melt separating seat 70, and heat generated by the hot melt heating unit 74 is transferred to the coating incision blade 72 mainly by heat conduction.

When the hot melting separation driver drives the two hot melting separation seats 70 to approach each other, the two cladding cutting blades 72 can respectively cut the cladding of the optical fiber 23 but not the core wire, the hot melting heating unit 74 transfers heat to the optical fiber 23 through the cladding cutting blades 72, the cladding of the optical fiber is softened and melted under the action of high temperature, and the cladding at the cutting position of the cladding cutting blades 72 can be easily separated. The two coating clamping portions 71 can clamp the coating below the cut, and when the stripping driver 51 drives the fiber stripping frame 5 to descend, the clamping force of the coating clamping portions 71 can tear the cut of the coating cutting blade 72 to strip the coating, as shown in fig. 11. Fig. 11 is a schematic diagram of the fiber stripping frame being driven to descend or descending, that is, the schematic diagram can be expressed in the stripping process that the cladding has been stripped from the optical fiber wire or after the stripping state has been completed.

Specifically, the coating cutting blade 72 is provided at an upper portion of the coating clamping portion 71, the cutting blade 63 is provided at a lower portion of the coating clamping portion 71, and the heat-melting heating unit 74 also transfers heat to the optical fiber wire coating through the coating clamping portion 71. It is understood that the heat-fusible heating unit 74 can directly transfer heat to the optical fiber wire coating through the coating clamping portion 71, and at the same time, since the heat transfer to the optical fiber wire coating is also thermally conductive, it is understood that the heat-fusible heating unit 74 transfers heat to the optical fiber wire 23 through the coating cutting blade 72.

In one embodiment of the automatic fiber stripping device, because cutting and hot melting can be performed synchronously, the fiber tail cutting seat 61 in the fiber tail cutting device 6 and the hot melting separation seat 70 in the hot melting separation device 7 can be an integral piece, which is collectively referred to as a seat body of the automatic fiber stripping device. That is, the fiber stripping frame 5 is equivalently provided with two slidable seat bodies. Meanwhile, the fiber tail cutting driver 62 and the thermal fusion separation driver may be the same component, and the fiber tail cutting driver 62 may also serve as the thermal fusion separation driver, which is called as a driving unit in the automatic fiber stripping device. In this embodiment, the coating cutting blade 72 and the cutting blade 63 are provided on the holder body at intervals in the extending direction a of the optical fiber. Hereinafter, each of the seat bodies may refer to a combination of the filament tail cutting seat 61 and the thermal fusion separating seat 70, and the driving unit refers to the filament tail cutting driver 62 and the thermal fusion separating driver.

Through the arrangement of the two seat bodies and the coating cutting-in blade 72, the cutting blade 63 and the hot-melting heating unit 74 which are respectively arranged on the two seat bodies, when the two seat bodies move relative to each other, the two seat bodies can clamp the optical fiber wire to be stripped, and heat generated by the hot-melting heating unit 74 is transferred to the clamped optical fiber wire through the coating cutting-in blade 72. At the same time, the two coating cutting blades 72 can cut the coating of the optical fiber wire, respectively, but not the core wire, so that the coating softened after being heated can be easily peeled off from the core wire, and the two cutting blades 63 can cut the optical fiber wire so that the ends of the plurality of optical fiber wires are flush. Therefore, clamping, cladding cutting and fiber tail cutting of the optical fiber are synchronously performed, and a foundation is provided for automatic fiber stripping.

The automatic fiber stripping device further comprises a fiber stripping frame driving unit (stripping driver) 51, wherein the fiber stripping frame driving unit 51 is arranged between the fiber stripping frame 5 and the rack 1 and can drive the fiber stripping frame 5 to move along the extension direction a of the optical fiber. So as to realize that the fiber stripping frame 5 and the two seat bodies arranged on the fiber stripping frame are driven to lift or descend along the extending direction a of the optical fiber line together.

When the two driving units drive the two base bodies to move relative to each other to the clamping position shown in fig. 7, the hot melting heating unit 74 effectively melts the cladding of the optical fiber, and simultaneously the two cladding cutting blades 72 respectively cut into the cladding of the optical fiber, at this time, the fiber stripping frame driving unit 51 drives the fiber stripping frame 5 to move down integrally, and the clamping force of the cladding clamping portion 71 can tear the cutting points of the two cladding cutting blades 72, so as to drive the section of cladding to be separated from the core wire of the optical fiber 23. Because the relative height positions of the cladding cutting blade 55 and the cutting blade 56 on the base body 52 are relatively fixed, the height difference between the cutting point of the cladding cutting blade 55 and the cutting point of the cutting blade 56 is kept unchanged, the length of the cladding stripped after hot melting is kept consistent, and the fiber stripping precision is high.

In one embodiment of the automatic fiber stripping apparatus, the heat-melting heating unit 54 is an electric heating rod, and the heat generated by the electric heating rod is transferred to the clamped optical fiber mainly by heat conduction.

In one embodiment of the automatic fiber stripping apparatus, the two coating cutting blades 72 in the fiber tail processing assembly are adjustable toward or away from the optical fiber line to be clamped. In the case of optical fiber wires, the coating layer wrapped around the inner core sometimes has different layer thicknesses due to production process errors, resulting in optical fiber wires having different diameters. If the optical fiber with larger diameter is excessively clamped, the cladding of the optical fiber can be damaged or even broken, and the two cladding cutting-in blades 72 are arranged on the base body to be adjustable, so that the two cladding cutting-in blades 72 can be prevented from excessively cutting in the cladding of the optical fiber to damage the core wire of the optical fiber. In particular, the adjustable setting of the two-layer cutting edge 72 can be achieved by: if the housing body is provided with a slot, the coating cutting edge 72 can be fixedly connected with the housing body through the slot and the fastener, and the coating cutting edge 72 can be adjusted by adjusting the position of the fastener in the slot.

In one embodiment of the automatic fiber stripping device, in a portion not shown in the figure, the fiber stripping frame 51 is further provided with a limiting unit, such as a boss structure, for each of the two seat bodies. The limiting unit limits the two base bodies to move relative to each other at the clamping position as shown in fig. 7, and ensures that one of the two base bodies does not move towards the other base body too much, so that the optical fiber line to be clamped can not be clamped at the designated position. The structure of the position-limiting unit is similar to that of the existing position-limiting structure, and is not described herein again.

In one embodiment of the automatic fiber stripping device, the fiber tail cutting seat 61 comprises a mounting groove 610 and limiting edges 611 arranged at two sides of the mounting groove 610, and the coating cutting blade 72 is mounted in the mounting groove 610. In the clamping position shown in fig. 7, the two limiting edges 611 at the corresponding positions between the two fiber tail cutting seats 61 respectively limit the depth of the two coating cutting edges 72 cutting into the optical fiber coating, and further prevent the two coating cutting edges 72 from excessively cutting into the optical fiber coating to damage the core.

As shown in fig. 10, in one embodiment of the automatic fiber stripping apparatus, a tail cutting base 61 is provided with a cutting blade blower corresponding to a cutting blade 63. The cutting knife blower is used for blowing the cutting knife edge 63 with strong force after cutting is finished, blowing off waste materials possibly stuck on the cutting knife edge 63, and avoiding the influence of the waste materials on the next cutting of the cutting knife edge 63. The cutting knife blower comprises a blowing air distribution channel 64 formed in a fiber tail cutting seat 61, and a plurality of blowing holes 65 which are communicated with the blowing air distribution channel 64 and are arranged in one-to-one correspondence with cutting positions of cutting knife edges 63 are formed in the fiber tail cutting seat 61. Of course, the blowing and air distributing passage 64 is connected to a control valve and a fan or an air compressor, which are well known and commonly used technologies, and are not described herein and not shown in the drawings.

Further, in one embodiment, the blowing holes 65 are also provided in correspondence with the coating cutting edges 72, so that the blowing unit can blow strongly towards the coating cutting edges 72 to blow off possibly stuck waste material.

Further, in one embodiment, the blowing wind channel 64 of the cutting blade blower may double as the blowing wind channel 64 of the coating blade blower, which draws the blowing holes 65 that cut into the blade 72 toward the coating directly from the blowing wind channel 64 of the cutting blade blower. The coating cutting blade 72 and the cutting blade 63 may be simultaneously blown by one blowing unit, or two blowing units may be used, for example, a coating cutter blower is provided for the coating cutting blade 72, and a cutting cutter blower is provided for the cutting blade 63 to respectively control the blowing.

In an embodiment of the automatic fiber stripping device, the automatic fiber stripping device further includes a waste collecting assembly (waste collector) 52, wherein the waste collecting assembly 52 is disposed on the frame 1 or the fiber stripping frame 51, and is disposed corresponding to the clamping position of the two seat bodies, and is disposed below the two seat bodies in height. The waste collection assembly 52 is shown in the drawings as being of a box-like construction having a space within which waste is collected. The waste material cut by the cutting blade 63 and the waste material peeled by the two seat bodies can fall into the waste material collecting assembly 52 under the action of self-gravity to be collected. The waste collecting assembly 52 is only required to be positioned right below the blanking positions of the fiber tail cutting device 6 and the hot melting separation device 7.

In one embodiment of the automatic fiber stripping device, as shown in fig. 1, a fiber stripping and cleaning assembly (fiber stripping and cleaning device) 8 is further disposed on the frame 1, the position of the fiber stripping and cleaning assembly 8 is a cleaning station on the frame 1, and the fiber stripping and cleaning assembly 8 includes a cleaning tank 81, a cleaning tank lifting and driving unit (cleaning tank lifting driver) 82, and an ultrasonic cleaning unit (ultrasonic transducer). The cleaning tank 81 contains a cleaning liquid therein, and the cleaning tank lifting drive unit 82 is disposed on the frame 1 and can drive the cleaning tank 81 to move along the extending direction a of the optical fiber, so as to realize the lifting or lowering in the extending direction a of the optical fiber. After fiber stripping, fine grease may inevitably remain on the stripped core wire, which can be cleaned by the fiber stripping cleaning assembly 8. Specifically, the transmission driving assembly 3 drives the optical fiber wire carrier 2 to the cleaning station after the fiber stripping is completed. The cleaning tank lifting drive unit 82 drives the cleaning tank 81 to lift up, the core wire portion of the stripped coating on the optical fiber 23 is immersed in the cleaning liquid in the cleaning tank 81, and the ultrasonic wave is turned on, thereby realizing the cleaning operation. After the cleaning, the ultrasonic wave is turned off, the cleaning tank lifting driving unit 82 drives the cleaning tank 81 to descend, and the transmission driving assembly 3 can continuously transmit the optical fiber carrier 2. The arrangement of the cleaning tank 81, the cleaning liquid and the ultrasonic cleaning unit is easy for those skilled in the art to obtain according to the structural principle of the existing ultrasonic cleaning machine, and is not described herein again.

In one embodiment of the automatic fiber stripping device, the fiber optic cable clamps 22 disposed in the fiber optic cable carrier 2 are symmetrically disposed as shown in the figure, so that two fiber stripping stations and two cleaning stations are correspondingly disposed on the frame 1. Therefore, the optical fiber wire clamp 22 can complete more fiber stripping and cleaning work of the optical fiber wire 23 by one-time transmission, and the fiber stripping efficiency is further improved.

In one embodiment of the fiber tail processing assembly, a first heat insulation unit 58 is disposed between the driving unit and the housing, so as to prevent the driving unit from being affected by heat generated by the housing.

In one embodiment of the fiber tail processing assembly, the fiber stripping frame 5 is provided with a slide rail 510 and a slide block 511, and the seat body is connected with the slide block 511, so that the seat body slides along the slide rail 510 on the fiber stripping frame 5. A second heat insulation unit 512 is disposed between the seat 5 and the sliding block 511, and is also used to prevent the sliding block 511 or the sliding rail 511 from being affected by heat generated by the seat.

In one embodiment of the fiber tail processing assembly, the coating cutting edge 72 is a V-notch edge as shown to facilitate cutting of the fiber optic strand coating and the cutting edge 63 is a flat-notch edge to facilitate cutting of the fiber optic strand end.

In one embodiment of the fiber tail processing assembly, one of the two bodies has a protrusion 524, and the other has a groove at a corresponding position, and the groove and the protrusion 524 can be guided at a position where the two bodies are close to each other.

In one embodiment of the fiber tail treatment assembly, the drive unit is a pneumatic cylinder.

In one embodiment of the fiber tail processing assembly, a temperature control unit (temperature controller) 75 is disposed in the housing, and the temperature control unit 75 is connected to the hot-melting heating unit 74 to detect the temperature of the housing heated by the hot-melting heating unit 74.

In the present embodiment, the optical fiber 23 to be stripped is placed in the optical fiber placing basket 21 of the optical fiber carrier 2, and one end to be stripped is primarily fixed by the optical fiber clamp 22. The fiber optic line 23 extends downwardly beyond the fiber clamp 22 by a length that is preferably greater than the distance from the cutting edge 63 to the lower end of the fiber clamp 22. The transmission driving device 3 drives the optical fiber carrier 2 to a fiber stripping station, the plurality of optical fiber wires 23 preliminarily fixed on the optical fiber clamp 22 reach the optical fiber guiding and clamping device 4, and the optical fiber guiding and clamping device 4 guides and clamps the plurality of optical fiber wires 23. After the guide clamping, the lower end of the optical fiber wire 23 can be easily formed into a straight vertical state. The fiber tail cutting driver 62 drives the two fiber tail cutting seats 61 to approach each other, the two cutting blades 63 firstly carry out uniform cutting on the bottom ends of the plurality of optical fiber wires 23, and the cut waste automatically falls into the waste collector 52. The portions of the coating to be peeled are then clamped by the two coating clamps 71, and simultaneously with the clamping, the corresponding coating cutting edges 72 cut into the upper ends of the coatings to be peeled. After the cladding of the optical fiber wire is effectively melted, the peeling driver 51 drives the fiber peeling frame 5 to move down integrally. The clamping force of the cladding clamps 71 may cause the entry point to tear and peel the cladding from the core. Because the cladding cutting blade 72 and the cutting blade 63 are relatively fixed, the height difference between the cutting point of the cladding cutting blade 72 and the cutting point of the cutting blade 63 is kept unchanged, the length of the cladding peeled off after hot melting is kept consistent, and the fiber stripping precision is high. After the coating is completely separated from the core wire, the tail cutting driver 62 drives the two tail cutting seats 61 to be away from each other, and the stripped coating loses the clamping effect and can freely fall into the waste collector 52. The stripping driver 51 drives the stripping frame 5 to return integrally, and the optical fiber guide clamping device 4 releases the guide clamping function. At this time, the optical fiber 23 on the optical fiber clamp 22 is not subjected to external force, the transmission driving device 3 drives the optical fiber carrier 2 to reach the cleaning station, and the fiber stripping and cleaning device 8 can effectively clean the stripped core wire part.
