The soft glue 37 can protect the optical fiber 6 from being squeezed and deformed inside the exposed optical fiber 6 after passing through the heat stripping module 2 and being damaged, which affects the performance of the optical fiber 6.

[0042] In an optional embodiment, if Figure 3 and Figure 5As shown, the cutting knife assembly 31 includes a sliding seat 311 and a blade 312.

The blade 312 driving motor drives the blade 312 to rotate normally on the mounting position 313.

[0043] In an optional embodiment, if Figure 6 and Figure 7 As shown, it also includes a shell 7, a residual material collection box 8 and a clamp 9. The shell 7 is used to protect the cutting knife module 3 and the thermal stripping module 2. The guide assembly 5 includes a guide cylinder 51 and a sliding portion 52. The guide cylinder 51 passes through the shell 7 and is laid on the surface of the second bracket 33 away from the device body 1. The sliding portion 52 is arranged on the peripheral side of the shell 7. The movable end of the sliding portion 52 is provided with the clamp 9. The clamp 9 clamps the optical fiber 6, and the sliding portion 52 pulls the optical fiber 6 to move in the direction away from the thermal stripping module 2. Specifically, the device body 1 is provided with a material receiving port 11, and the stripped coating layer of the optical fiber 6 enters the residual material collection box 8 through the material receiving port 11, which can prevent the residual material from popping out, ensuring safe operation while keeping the working environment clean and orderly; the shell 7 is provided with a limiting hole, and the guide cylinder 51 passes through the limiting hole. The guide cylinder 51 is in a funnel structure, and the large diameter end of the guide cylinder 51 is interference fit with the hole wall of the limiting hole, and the small diameter end is laid on the surface of the second bracket 33. The central axis of the guide cylinder 51 is consistent with the central line of the limiting groove 331 and the soft glue 37 to avoid displacement, so that the optical fiber 6 can accurately enter the thermal stripping module 2 and the cutting head assembly for corresponding operation; the sliding part 52 includes a base 521 and a slide rail 522, and the slide rail 522 moves in the opposite direction along the length of the base 521 to pull out the optical fiber 6; the clamp 9 is provided with a clamping groove, and the groove wall of the clamping groove is provided with a movable wall to clamp the optical fiber 6. In this embodiment, the clamp 9 can adopt a pneumatic clamp or an electric clamp; further, the clamp 9 can also be provided with a high-precision sensor and a ruler, which can detect the thickness of the optical fiber 6 in real time and automatically adjust the clamping force and position. At the same time, the ruler adopts a combination of electronic display and fine-tuning device, which is convenient for the operator to accurately adjust the reserved length of the optical fiber 6, greatly improving the adaptability of the tool to optical fibers 6 of different specifications.

[0044] Further, such as Figure 7As shown, the control structure 4 also includes a human-machine interaction interface, such as a display screen, operation buttons, etc. In this embodiment, the human-machine interaction interface adopts a touch screen, which is easy and intuitive to operate. The human-machine interaction interface clearly displays various parameter setting options, working status indicators and operation control buttons, which is convenient for operators to quickly set parameters, monitor the working status in real time and perform precise operation control. In order to improve the safety of the device, multiple sensing devices can also be set to immediately trigger a temporary shutdown function when an abnormal situation is detected. At this time, the device can not only stop the current operation, but also automatically return to the initial state and release the clamping of the optical fiber 6 clamp 9.

[0045] When in use, the optical fiber 6 is passed through the device from the guide assembly 5, and passes through the cutting head module through the guidance of the guide assembly 5, and the end of the optical fiber 6 enters the thermal stripping module 2, and the first drive motor 22 drives the movable clamping plate 212 to move toward the fixed clamping plate 211 to clamp the end of the optical fiber 6 and heat it. At this time, the second drive drives the clamping head 321 to be in the motor open state. When the heating is completed, the first drive motor 22 stops running, and the slide rail 522 cooperates with the clamp 9 to pull the optical fiber 6 out of the device. The heat-softened coating is separated from the inner lining of the optical fiber 6, and the exposed inner lining of the optical fiber 6 is retreated to the cutting knife assembly 31, so that the cutting point corresponds to the blade 312, and the movable clamping plate 212 is opened by the tension of the first tension spring 23, and the residual material falls into the residual material collection box 8, and the clamping head 321 is closed by the tension of the second tension spring 322, clamping the optical fiber 6, and the driving motor of the blade 312 drives the blade 312 to rotate, and the sliding motor drives the sliding seat 311 to move along the length direction of the limit groove 331, completing the automatic stripping and cutting of the optical fiber 6.

[0046] In summary, the device can realize the automation of processes such as coating stripping and end face cutting of optical fiber 6, and the automated operation and precise control can effectively reduce the damage of optical fiber 6 and improve the flatness of the end face of optical fiber 6, thereby improving the fusion quality of optical cable joints and reducing signal transmission loss; it can significantly shorten the production time of a single optical cable joint, and can greatly improve work efficiency and reduce communication interruption time in batch production or emergency repair operations; the intelligent adjustment function makes it suitable for optical fibers 6 of various specifications, reduces the dependence on operator experience, and facilitates popularization and application; the friendly human-computer interaction interface makes it easy for operators to get started and reduces the difficulty of operation.
