Fiber stripping device for butterfly cables

Technical Field

The invention relates to the field of optical cables, and in particular to a fiber stripping device for butterfly cables.

Background technique

The butterfly optical cable is also called the butterfly cable. As shown in Figure 1, the butterfly cable used outdoors has higher requirements for tensile strength. Therefore, the butterfly cable used outdoors includes a main body part and a suspension wire part. The main body part includes optical fiber and a sheath. In order to enhance the strength of the main body part, the main body part also includes reinforcing elements symmetrically arranged on both sides of the optical fiber; the suspension wire part includes a reinforcing member and a sheath. The suspension wire part is connected to the main body part to improve the tensile strength of the optical cable.

Before making the fiber optic connector of the butterfly cable, a certain length of the suspension wire part will be removed, and then the fiber stripping operation will be performed. The specific fiber stripping operation is: the worker uses wire strippers to strip the bare optical fiber of the specified length from the main body.

The existing fiber stripping operation is completed manually, which has the problems of high labor intensity, low production efficiency, and unstable work quality.

Summary of the invention

In view of the above problems, the present invention overcomes at least one disadvantage and proposes a fiber stripping device for butterfly cables, which can reduce labor intensity, improve production efficiency and ensure relatively stable fiber stripping quality.

The technical solution adopted by the present invention is as follows:

A fiber stripping device for a butterfly cable, comprising:

Scaffolding;

A traction mechanism, installed on the base frame, is used to traction the conveying butterfly cable;

A separation mechanism, used to split the butterfly cable from the traction mechanism, so that the main body part and the suspension wire part of the butterfly cable are separated;

a stripping mechanism for stripping the sheath and the reinforcing element of the body portion out of the separation mechanism;

The controller is used to control the operation of the traction mechanism and the stripping mechanism.

The butterfly cable can be transported by the traction mechanism, and the butterfly cable from the traction mechanism can be split by the separation mechanism, so that the main body of the butterfly cable and the suspension wire part are separated, and then the stripping mechanism is used to strip the separated main body, that is, to strip the sheath and reinforcement elements of the main body. The fiber stripping device can realize mechanized operation, which can reduce labor intensity, improve production efficiency, and ensure a more stable stripping quality compared to the existing manual operation.

In one embodiment of the present invention, the traction mechanism includes:

A pair of rollers that cooperate with each other, the two rollers are used to clamp and convey the butterfly cable;

A first driving assembly, used for driving at least one roller to rotate;

The inlet guide block has a first limit opening, which is aligned with the middle position of the two rollers and is used to guide the butterfly cable between the two rollers;

The outlet guide block and the inlet guide block are respectively arranged on the front and rear sides of a pair of rollers, and the outlet guide block has a second limiting opening, and the second limiting opening is aligned with the middle position of the two rollers.

The butterfly cable can enter and exit the traction mechanism through a pair of rotating rollers. The inlet guide block and the outlet guide block are respectively arranged on the front and rear sides of the pair of rollers, so that the butterfly cable can be limited by the first limit opening and the second limit opening, which can ensure that the butterfly cable is reliably transported by the rollers.

In one embodiment of the present invention, the two rollers are respectively a driving roller and a driven roller, and the traction mechanism further includes:

Two mounting seats, each of which has a slide groove, and both ends of the active roller are rotatably mounted on the corresponding mounting seats;

Two sliders are slidably mounted on corresponding slide grooves, and two ends of the driven roller are rotatably mounted on corresponding sliders;

The regulating spring is installed in the slide groove, one end of which is against the corresponding sliding block, and is used to make the driven roller have a movement tendency to move toward the driving roller.

The arrangement of the slide groove, the slider and the adjusting spring enables the driven roller to move adaptively according to the specific shape of the butterfly cable, thereby ensuring that the traction mechanism can work reliably.

Preferably, the driving roller is mounted on two mounting seats via rolling bearings, and the driven roller is mounted on two sliding blocks via rolling bearings.

Due to the effect of the adjusting spring, when the butterfly cable is not conveyed, the adjusting spring makes the two rollers tangent.

In one embodiment of the present invention, the traction mechanism further includes an adjusting bolt, which is threaded on the mounting seat, and one end of the adjusting bolt extends into the slide slot to abut against the adjusting spring to adjust the compression amount of the adjusting spring.

By setting the adjusting bolt, the compression amount of the adjusting spring can be adjusted, thereby adjusting the pressure of the compression spring so that the pressure between the driven roller and the driving roller meets the requirements, which will not damage the butterfly cable and ensure sufficient friction to transport the butterfly cable.

In one embodiment of the present invention, the traction mechanism further includes an L-shaped guide plate, the horizontal side of the guide plate is fixed to the base frame, and the vertical side of the guide plate has a first through hole corresponding to the first limit opening.

In actual use, due to the presence of the guide plate, the imported guide block can be fixed to the vertical side of the guide plate, and the mounting seat can also be fixed to the vertical side of the guide plate. This arrangement can not only ensure that the structure is fixed reliably, but also the guide plate can cover structures such as rollers, making it less likely to cause accidents during operation.

In one embodiment of the present invention, the first driving component includes:

Two gears are respectively mounted on the rotating shafts of the corresponding rollers, and the two gears mesh with each other;

The driving motor is used to drive the active roller to rotate.

The driving motor of the present application may or may not include a reduction gearbox, and the phrase "the driving motor is used to drive the active roller to rotate" of the present application means that the output shaft of the driving motor may be connected to the active roller via a coupling, or connected to the gear on the active roller via a coupling.

When the driving motor is working, it can drive the active roller to rotate. Because of the meshing of the two gears, the driven gear will also rotate. Both rollers have power, so the butterfly cable entering between the two rollers can be reliably transported.

In one embodiment of the present invention, the inlet guide block and the outlet guide block are both L-shaped structures, and both the inlet guide block and the outlet guide block include a vertical portion and a horizontal portion extending to the junction of the two rollers, and the first limit opening and the second limit opening are arranged on the corresponding horizontal portion.

The L-shaped structure enables the horizontal portion to be closer to the junction of the two rollers, so that the first limit opening and the second limit opening are closer to the junction of the rollers, ensuring reliable and stable transportation and correct positioning.

In one embodiment of the present invention, the separation mechanism comprises:

A separation knife seat is fixed relative to the base frame, and has a separation channel corresponding to the second limit opening;

A cutting knife is installed on the separation knife seat, and the cutting knife divides the separation channel into a first channel and a second channel. The cutting knife is used to split the butterfly cable from the second limiting opening to separate the main body part and the suspension wire part of the butterfly cable, wherein the separated main body part enters the first channel, and the separated suspension wire part enters the second channel.

The cutting knife is provided to split the butterfly cable from the second limit port, so as to separate the main body part and the suspension wire part of the butterfly cable; through the separation channel, the separated main body part enters the first channel, and the separated suspension wire part enters the second channel, which can effectively limit the direction of the separated main body part and the suspension wire part, prevent interference, and ensure the reliable implementation of the subsequent processes.

In one embodiment of the present invention, the cutting knife includes a second straight surface and a second guide surface, and the intersection of the second straight surface and the guide surface is the cutting edge of the cutting knife.

In one embodiment of the present invention, the peeling mechanism includes:

The fiber stripping pad has a first limiting channel, wherein the first limiting channel is used to receive the main body of the butterfly cable from the separation mechanism;

The stripping assembly is arranged on a side of the fiber stripping pad away from the separation mechanism and is used for stripping the sheath and the reinforcing element of the main body part coming out of the first limiting channel.

In one embodiment of the present invention, the fiber stripping device also includes a detection element, which is installed on a base frame, a fiber stripping pad or a stripping component, and is used to detect the main body and send a detection signal to a controller. The controller controls the stripping component to work according to the signal of the detection element.

The fiber stripping pad can receive the main body part coming out of the first channel and limit the main body part, thereby providing a guarantee for the subsequent fiber stripping operation of the stripping assembly. The moving main body part can be sensed by the detection element. In actual use, the detection element can be set on the side of the stripping assembly away from the fiber stripping pad. When the detection element detects the main body part, the controller controls the stripping assembly to work. In actual use, the detection element can also be installed on the fiber stripping pad or between the fiber stripping pad and the stripping assembly. At this time, the controller needs to delay control. Through delay control, the main body part can continue to move the set distance, so that the stripping assembly can also strip out optical fiber within a set length range.

In one embodiment of the present invention, the fiber stripping pad includes a block body and a cover plate, the block body has a first groove, and the first groove and the cover plate form the first limiting channel.

In one embodiment of the present invention, the stripping assembly includes:

The fiber stripping knife seat is relatively fixed to the base frame;

The fiber stripping cylinder, the cylinder body of the fiber stripping cylinder is relatively fixed to the base frame;

The second fiber stripping knife is relatively fixed to the piston rod of the fiber stripping cylinder. The first fiber stripping knife and the second fiber stripping knife both have avoidance recesses. When the piston rod of the fiber stripping cylinder is pushed outward, the first fiber stripping knife and the second fiber stripping knife cooperate with each other to cut off the sheath and reinforcement element of the main body part, and the two avoidance recesses form an avoidance hole for only the optical fiber to pass through.

When the stripping assembly is not working, there is space between the first fiber stripping knife and the second fiber stripping knife, through which the main body of the butterfly cable can pass. When the stripping assembly is working, the piston rod of the fiber stripping cylinder pushes outward, and the first stripping knife and the second stripping knife cooperate with each other to cut off the sheath and reinforcing element of the main body. The two avoidance recesses form an avoidance hole through which only the optical fiber passes. The piston rod of the fiber stripping cylinder keeps extending, and the traction mechanism works to retract the butterfly cable, so that the sheath and reinforcing element of the main body can be stripped off to obtain the required bare optical fiber.

In one embodiment of the present invention, the base frame has a first through hole, which is arranged on a side of the fiber stripping knife seat facing away from the fiber stripping pad, and is used for the sheath and reinforcing element that are partially stripped from the main body to fall through.

In order to facilitate the peeling off of the sheath and reinforcing element of the main body, an inclined pouring surface can be provided on the fiber stripping knife holder in actual use.

In one embodiment of the present invention, the first fiber stripping knife and the second fiber stripping knife both include a first body, the first body has a cutting blade, the cutting blade includes a first straight surface and a first inclined surface, the avoidance recess is arranged on the cutting blade, at least one side of the cutting blade has a limiting column, and the first body also has a limiting step; when the first fiber stripping knife and the second fiber stripping knife cooperate, the first straight surfaces of the two cutting blades contact and interlace with each other, the limiting column of the first fiber stripping knife abuts against the limiting step of the second fiber stripping knife, and the limiting column of the second fiber stripping knife abuts against the limiting step of the first fiber stripping knife, and the two avoidance recesses form the avoidance hole.

The first fiber stripping knife and the second fiber stripping knife are arranged in this way so as to more reliably cut off the sheath and the reinforcing element of the main body part. Through the cooperation of the limiting step and the limiting column, reliable positioning can be achieved to ensure the quality of fiber stripping.

In one embodiment of the present invention, the detection element is a displacement sensor or a photoelectric sensor, etc. For example, the main body can be detected by a diffuse reflection sensor.

In one embodiment of the present invention, the base frame includes a bottom plate, and the traction mechanism, the separation mechanism, and the peeling mechanism are all disposed on the bottom plate.

In the present application, the controller is used to control the action components of each mechanism, specifically, to control the operation of the motor and each cylinder.

The beneficial effects of the present invention are as follows: the butterfly cable can be transported by the traction mechanism, the butterfly cable from the traction mechanism can be split by the separation mechanism, so that the main body part and the suspension wire part of the butterfly cable are separated, and then the fiber stripping operation is performed on the separated main body part by the stripping mechanism, that is, the sheath and the reinforcing element of the main body part are stripped. The fiber stripping device can realize mechanized operation, which can reduce labor intensity, improve production efficiency and ensure stable fiber stripping quality compared with the existing manual operation.

The present invention is described in detail below in conjunction with the accompanying drawings.

Example 1

As shown in FIG2 , a cutting and stripping device for a butterfly cable comprises:

Base frame 7;

A traction mechanism 9, mounted on the base frame 7, is used to traction and convey the butterfly cable;

The separation mechanism 10 is used to split the butterfly cable from the traction mechanism 9 so as to separate the main body part and the suspension wire part of the butterfly cable;

a stripping mechanism 12 for stripping the sheath and the reinforcing element of the body portion coming out of the separation mechanism 10;

The cutting mechanism 11 is used to cut off the suspension wire portion coming out of the separation mechanism 10;

The controller is used to control the operation of the traction mechanism 9 , the stripping mechanism 12 and the punching mechanism 11 .

The butterfly cable can be transported by the traction mechanism 9, and the butterfly cable from the traction mechanism 9 can be divided by the separation mechanism 10, so that the main body part and the suspension wire part of the butterfly cable are separated, and then the separated suspension wire part is cut by the punching mechanism 11 to cut off a section of the suspension wire part, and the separated main body part is stripped by the stripping mechanism 12 to strip the sheath and reinforcement elements of the main body part to obtain a section of bare optical fiber. The cutting and stripping device of the present application can realize mechanized operation, and compared with the existing manual operation, it can reduce labor intensity, improve production efficiency, and ensure a more stable cutting and stripping quality.

As shown in FIGS. 3 , 4 , 5 and 6 , in this embodiment, the traction mechanism 9 includes:

A pair of rollers that cooperate with each other, the two rollers are used to clamp and convey the butterfly cable;

A first driving assembly, used for driving at least one roller to rotate;

The inlet guide block 17 has a first limit opening 21, and the first limit opening 21 is aligned with the middle position of the two rollers, and is used to guide the butterfly cable between the two rollers;

The outlet guide block 18 and the inlet guide block 17 are respectively arranged at the front and rear sides of a pair of rollers. The outlet guide block 18 has a second limiting opening 22, and the second limiting opening 22 is aligned with the middle position of the two rollers.

The butterfly cable can enter and exit the traction mechanism 9 through a pair of rotating rollers. The inlet guide block 17 and the outlet guide block 18 are respectively arranged on the front and rear sides of the pair of rollers, so that the butterfly cable can be limited by the first limit opening 21 and the second limit opening 22, so that the butterfly cable is in the correct transmission position, ensuring that the butterfly cable is reliably transported by the rollers.

As shown in FIGS. 3 , 5 and 6 , in this embodiment, the two rollers are respectively a driving roller 23 and a driven roller 24 , and the traction mechanism 9 further includes:

Two mounting seats 25, namely a main mounting seat and an auxiliary mounting seat, each of the two mounting seats 25 has a slide groove 26, and both ends of the active roller 23 are rotatably mounted on the corresponding mounting seats 25;

Two sliders 27 are slidably mounted on the corresponding slide grooves 26, and two ends of the driven roller 24 are rotatably mounted on the corresponding sliders 27;

An adjusting spring 28 is installed in the slide groove 26, one end of which is against the corresponding slider 27, so as to make the driven roller 24 have a movement tendency to move toward the driving roller 23;

The first drive assembly comprises:

Two gears 29 are respectively mounted on the rotating shafts of the corresponding rollers, and the two gears 29 are meshed with each other;

The driving motor 30 is used to drive the active roller 23 to rotate.

The arrangement of the slide groove 26, the slider 27 and the adjusting spring 28 enables the driven roller 24 to move adaptively according to the specific shape of the butterfly cable, thereby ensuring that the traction mechanism 9 can work reliably.

Preferably, the driving roller is mounted on two mounting seats via rolling bearings, and the driven roller is mounted on two sliding blocks via rolling bearings.

Due to the effect of the adjusting spring, when the butterfly cable is not conveyed, the adjusting spring makes the two rollers tangent.

In actual use, the drive motor 30 may or may not include a reduction gearbox. In this application, "the drive motor 30 is used to drive the active roller 23 to rotate" means that the output shaft of the drive motor 30 can be connected to the active roller 23 through a coupling, or connected to the gear 29 on the active roller 23 through a coupling.

When the driving motor 30 is working, it can drive the active roller 23 to rotate. Because of the meshing action of the two gears 29, the driven gear will also rotate. Both rollers have power, so that the butterfly cable entering between the two rollers can be reliably transported. By switching the rotation direction of the driving motor 30, the forward and backward operations of the butterfly cable can be realized. Specifically, the butterfly cable is controlled to move forward first. When the stripping mechanism 12 works, the driving motor 30 is controlled to rotate in the opposite direction to make the butterfly cable move backward.

As shown in Figs. 3, 5 and 6, in this embodiment, the traction mechanism 9 further includes an adjusting bolt 31, which is screwed on the mounting seat 25, and one end of the adjusting bolt 31 extends into the slide slot 26, and abuts against the adjusting spring 28, so as to adjust the compression amount of the adjusting spring 28. By setting the adjusting bolt 31, the compression amount of the adjusting spring 28 can be adjusted, thereby adjusting the pressure of the compression spring, so that the pressure between the driven roller 24 and the driving roller 23 meets the requirements, which will not damage the butterfly cable, and can ensure sufficient friction to transport the butterfly cable.

As shown in Figs. 3 and 6, in this embodiment, the traction mechanism 9 further includes an L-shaped guide plate 13, the horizontal side 14 of the guide plate 13 is fixed to the base frame 7, and the vertical side 15 has a first through hole 16 corresponding to the first limit opening 21. In actual use, due to the existence of the guide plate 13, the inlet guide block 17 can be fixed to the vertical side 15 of the guide plate 13, and the mounting seat 25 can also be fixed to the vertical side 15 of the guide plate 13. Such a setting can not only ensure that the structure is fixed reliably, but also the guide plate 13 can shield the roller and other structures, so that accidents are not likely to occur during operation.

As shown in Figs. 6 and 8, in this embodiment, the inlet guide block 17 and the outlet guide block 18 are both L-shaped structures, and both the inlet guide block 17 and the outlet guide block 18 include a vertical portion 19 and a horizontal portion 20 extending toward the junction of the two rollers, and the first limiting opening 21 and the second limiting opening 22 are arranged on the corresponding horizontal portion 20. The L-shaped structure enables the horizontal portion 20 to be closer to the junction of the two rollers, so that the first limiting opening 21 and the second limiting opening 22 are closer to the junction of the rollers, ensuring reliable and stable transportation and correct positioning.

As shown in Figure 6, in order to facilitate the insertion of the butterfly cable, the cross-sectional area of the first through hole 16 gradually increases, and the farther away from the first limit opening 21, the larger the cross-sectional area of the first through hole 16; in order to facilitate the butterfly cable to enter the second limit opening 22, the cross-sectional area of the second limit opening 22 gradually increases, and the closer to the inlet guide block 17, the larger the cross-sectional area of the second limit opening 22.

As shown in Fig. 7, in this embodiment, the cutting knife 33 includes a second straight surface 37 and a second guide surface 38. The intersection of the second straight surface 37 and the guide surface is the blade of the cutting knife 33. The second guide surface 38 is located on the side where the first channel 35 is located. The second guide surface 38 is an inclined surface or an arc surface, and the suspension wire part is not easily deformed. After the second guide surface 38 is located on the side where the first channel 35 is located, it is convenient to guide the divided body part so that the divided body part and the suspension wire part are separated from each other.

The fiber stripping pad 39 can receive the main body part coming out of the first channel 35 and limit the main body part, providing a guarantee for the fiber stripping operation of the stripping assembly later. When the stripping assembly is not working, there is a space between the first fiber stripping knife 44 and the second fiber stripping knife 46, which can allow the main body part of the butterfly cable to pass through. When the stripping assembly is working, the piston rod of the fiber stripping cylinder 45 pushes outward, and the first stripping knife and the second stripping knife cooperate with each other to cut off the sheath and reinforcing element of the main body part.

The setting of the limit hole 59 can receive and limit the suspension wire portion from the second channel 36, preventing the suspension wire portion from bending to other areas, affecting the work of other structures or affecting the falling of the suspension wire portion after cutting. The second through hole 60 corresponding to and connected to the limit hole 59 is set on the base frame 7, so that the cut suspension wire portion can fall down.

As shown in Fig. 10, in this embodiment, the side wall of the limiting hole 59 away from the separation mechanism 10 is an inclined side wall 61. This arrangement facilitates the reliable drop of the cut suspension wire part.

As shown in Fig. 2, in this embodiment, the base frame 7 includes a bottom plate 8, and the traction mechanism 9, the separation mechanism 10, the peeling mechanism 12 and the cutting mechanism are all arranged on the bottom plate 8. In this application, the controller is used to control the action components of each mechanism, specifically, to control the operation of the drive motor 30 and each cylinder.

As shown in FIG7 , in this embodiment, the cutting and stripping device further includes a detection element 54, which is mounted on the fiber stripping pad 39 for detecting the main body and sending a detection signal to the controller. The controller controls the stripping assembly and the punching and cutting mechanism 11 to work according to the signal of the detection element 54. In actual use, when the controller receives the signal of the detection element 54, it controls the fiber stripping cylinder 45 and the punching and cutting cylinder 57 of the stripping assembly to work according to the delay setting time. The purpose of the delay setting time is to enable the main body to continue to move the set distance, so that the stripping assembly can strip the optical fiber within the set length range. When the fiber stripping cylinder 45 works, the piston rod of the fiber stripping cylinder 45 pushes to cut off the sheath and reinforcing element of the main body, and keeps the piston rod of the fiber stripping cylinder 45 stationary. The driving motor 30 of the traction mechanism 9 rotates in the opposite direction to drive the butterfly cable to retreat and retract, so that the bare optical fiber can be obtained. In actual use, two delay times can also be set to delay the control of the punching and cutting mechanism 11 and the stripping assembly to work.

In addition to being installed on the fiber stripping pad 39 , the detection element 54 may also be installed on the base frame 7 or the stripping assembly. In other embodiments, the detection element 54 may be disposed on a side of the stripping assembly away from the fiber stripping pad 39 .

In addition to detecting the main body, the detection element 54 can also be used to detect the suspension wire in other embodiments. In this case, the detection element 54 can be installed on the limit block 58 or the base frame 7. When the detection element 54 detects the suspension wire, the controller can control the punching and cutting cylinder 57 to work, and then control the stripping mechanism 12 to work after a delay of a set time. It is also possible that after the detection element 54 detects the suspension wire, the punching and cutting cylinder 57 can be controlled to work after a delay of a first set time, and the stripping mechanism 12 can be controlled to work after a delay of a second set time.

The purpose of various delay controls is to ensure that the length of the cut-off suspension wire portion and the length of the stripped main body portion meet the requirements.

In actual use, the detection element 54 is a displacement sensor or a photoelectric sensor, etc. For example, the body part or the suspension wire part can be detected by a diffuse reflection sensor.

In actual use, a trash can can be arranged below the two through holes to collect waste materials.

The specific working process of the cutting and stripping device for butterfly cables in this embodiment is as follows:

The end of the butterfly cable is extended into the first through hole 16 of the guide plate 13. After passing through the first through hole 16, the butterfly cable enters the first limiting opening 21 of the inlet guide block 17, and then enters between the active roller 23 and the driven roller 24. By driving the positive rotation of the motor, the two rollers transmit the butterfly cable backward, and the outlet guide block 18 close to the roller receives and limits the butterfly cable through the second limiting opening 22, and then guides the butterfly cable into the separation mechanism 10;

The blade of the cutting knife 33 of the separation mechanism 10 is aligned with the connection between the main body part and the suspension wire part, and the cutting knife 33 cuts the butterfly cable to separate the main body part and the suspension wire part of the butterfly cable, and the separated main body part enters the first channel 35 through the separation channel 34, and the separated suspension wire part enters the second channel 36. After the main body part comes out of the separation channel 34, it enters the first limiting channel of the fiber stripping pad 39, and the suspension wire part comes out of the separation channel 34 and enters the limiting hole 59 of the limiting block 58;

The separated body part and the suspension wire part continue to be transported backwards driven by the rollers. When the detection element 54 detects the body part, it sends a signal to the controller. The controller controls the punching cylinder 57 of the punching mechanism 11 to work according to the specified delay. The piston rod of the punching cylinder 57 pushes the first punching knife and the second punching knife 56 to cooperate with each other to cut off the suspension wire part from the second channel 36, thereby realizing the cutting operation. The cut suspension wire part falls out of the base frame 7 through the second through hole 60.

The roller continues to rotate, and after the set delay time, the controller controls the drive motor 30 to stop working and controls the piston rod of the fiber stripping cylinder 45 to push. The first stripping knife and the second stripping knife cooperate with each other to cut off the sheath and reinforcement elements of the main body. The two avoidance recesses 47 form an avoidance hole for only the optical fiber to pass through. The piston rod of the fiber stripping cylinder 45 keeps pushing action, and the controller controls the drive motor 30 to rotate in the opposite direction to drive the butterfly cable to retract. In this state, the optical fiber is pulled out of the sheath, and the separated sheath and reinforcement elements of the main body fall through the first through hole 62. When the end of the spiral cable retracts to the first through hole 16, the motor resumes forward rotation and completes a cycle.

Example 2

This embodiment discloses a fiber stripping device for a butterfly cable. The difference between this embodiment and embodiment 1 is that the punching mechanism 11 is removed. The fiber stripping device cannot cut the suspension wire part, but can perform a stripping operation on the main body part to obtain a bare optical fiber. The removal of the suspension wire part at a later stage can be performed manually or by other equipment. Compared with the existing fiber stripping operation, the fiber stripping device of this embodiment can improve efficiency, reduce labor intensity, and ensure a relatively stable processing quality. It should be noted that, preferably, the detection element 54 in this embodiment is used to detect the main body part. After the detection element 54 detects the main body part, the controller controls the fiber stripping cylinder 45 to work.

Example 3

This embodiment discloses a cutting device for butterfly cables. The difference between this embodiment and embodiment 1 is that the stripping mechanism 12 is removed. The cutting device cannot strip out the bare optical fiber, but can cut off the suspension wire portion. Compared with manual tearing and cutting, it can improve efficiency, reduce labor intensity, and ensure a more stable processing quality. The later fiber stripping operation of the main body can be performed using background technology or other equipment. It should be noted that the detection element 54 in this embodiment is used to detect the suspension wire portion. After the detection element 54 detects the suspension wire portion, the controller controls the punching cylinder 57 to work.
