Technical field

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

Background technique

Butterfly optical cable is also called butterfly cable. As shown in Figure 1, the butterfly cable used outdoors has higher tensile strength requirements. Therefore, the butterfly cable used outdoors includes a body part 1 and a suspension part 2. The body part includes optical fiber 3 and Sheath 5, in order to enhance the strength of the body part, the body part also includes reinforcing elements 4 symmetrically arranged on both sides of the optical fiber; the suspension line part includes reinforcing members 6 and sheath 5, and the suspension line part is connected to the body part to improve the resistance of the optical cable.

When making a connector, there is no need for a hanging wire part, so the company will pre-remove the hanging wire part of a specified length during production, and then proceed with the rest of the work. By removing the hanging wire part, the head of the butterfly cable has good bendability when used on site.

The existing method of removing a section of the hanging wire is divided into three steps. The first step is for the worker to use scissors to cut a hole at the connection between the body part and the hanging wire part. The second step is for the worker to use the strength of his wrist to cut the hanging wire part along the front. The opening is torn to the specified length. The third step is for the worker to use large calipers to cut off the root of the torn hanging wire.

When making a connector, after removing a section of the hanging wire, a section of bare optical fiber needs to be stripped out. The existing stripping operation is as follows: workers use wire strippers to strip the body part of the bare optical fiber to a specified length.

The above operation methods have problems such as high labor intensity, low production efficiency, and unstable work quality.

The detection element is used to detect the hanging wire part and send the detection signal to the controller. The controller controls the punching cylinder and the peeling mechanism based on the signal from the detection component.

In actual application, when the detection element detects the hanging wire part, the work of the peeling mechanism and the punching mechanism can be controlled according to the delay setting time. The purpose of this control is to ensure the combined requirements of the length of the cut suspension line part and the length of the stripped body part.

In actual use, when the controller receives the signal from the detection element 54, it controls the work of the stripping cylinder 45 and the punching cylinder 57 of the stripping assembly according to the delay set time. The purpose of the delay set time is to enable the body part to continue to move the device. The distance is set, so that the stripping component can strip out the optical fiber within the set length range. When the fiber stripping cylinder 45 is working, the piston rod of the fiber stripping cylinder 45 pushes to cut off the sheath and reinforcing elements of the body part, and keeps the fiber stripping cylinder 45 The piston rod does not move, and the drive motor 30 of the traction mechanism 9 rotates in the opposite direction to drive the butterfly cable to retract backward, so that the bare optical fiber can be obtained.

In this case, the detecting element 54 can be installed on the limiting block 58 or the base frame 7 , and the hanging wire can be detected on the detecting element 54 Partially, the controller controls the punching cylinder 57 to work, and then controls the peeling mechanism 12 to work after delaying the set time. It is also possible to control the punching cylinder 57 to operate after a first set time delay after the detection element 54 detects the hanging wire portion, and then control the peeling mechanism 12 to operate after a second set time delay.

The purpose of various delay controls is to ensure the combined requirements of the length of the cut off hanging wire part and the length of the stripped body part.

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

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

Extend the end of the butterfly cable 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 limit opening 21 of the inlet guide block 17, and then enters between the driving roller 23 and the driven roller 24. During this time, through the forward rotation of the drive motor, the two rollers transmit the butterfly cable backwards, and the exit guide block 18 close to the rollers receives and limits the butterfly cable through the second limiting port 22, and then introduces 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 body part and the hanging wire part. The cutting knife 33 separates the butterfly cable to separate the body part and the hanging wire part of the butterfly cable. Through the separation channel 34, the separated body Part of it enters the first channel 35, the separated hanging wire part enters the second channel 36, the body part comes out of the separation channel 34 and enters the first limiting channel of the fiber stripping pad 39, and the hanging wire part comes out of the separating channel 34 and enters the limiting channel in the limiting hole 59 of the block 58;

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

The roller continues to rotate. After delaying the set 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 sheath and strengthen the body part. The component is cut off, and the two avoidance notches 47 form an escape hole only for the optical fiber to pass through. The piston rod of the fiber stripping cylinder 45 keeps pushing, and the controller then 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 from the sheath, and the sheath and reinforcing element of the separated body part fall through the first through hole 62. When the end of the screw cable retracts to the first through hole 16, the motor resumes forward rotation, completing the process. A cycle.
