[0044] In some embodiments, in order to reduce the wear of the optical fiber during the fiber guiding process and achieve the purpose of lossless fiber guiding, the surfaces of the fiber optic reel 160, the fiber guiding structure 150 and the fiber cutting structure 140 provided in this embodiment that are in contact with the optical fiber 200 can all be made of Teflon material.

[0045] Optional, see Figure 2a and Figure 2b , Figure 2a and Figure 2b is a structural schematic diagram of a fiber cutting structure provided by an embodiment of the present invention, such as Figure 2a and Figure 2b As shown, the fiber cutting structure 140 provided in this embodiment may include an encoder 141 and a pneumatic scissor head 142, the encoder 141 having a roller group, the fiber guiding structure 150 being used to guide the optical fiber 200 to sequentially pass through the conveying gap between the roller group and the fiber cutting gap of the pneumatic scissor head 142, the fiber cutting structure 140 determines the optical fiber length information by calculating the number of turns of the roller in the roller group driven by the optical fiber 200 passing through the conveying gap through the encoder 141.

At the same time, the protective structure 143 covers the cutting edge of the pneumatic scissor head 142, which can prevent the pneumatic scissor head 142 from causing damage to the fingers of the staff, thereby ensuring the safety of the automatic fiber guiding device 100 provided in this embodiment.

Specifically, in order to achieve the purpose of lossless fiber guiding, the material of the first limiting structure 144 and the second limiting structure 145 provided in this embodiment can also be Teflon material.

In this way, in order to realize the automatic fiber guiding function of the automatic fiber guiding device 100 provided in this embodiment, this embodiment can send a control instruction to the driving motor 162 through the PLC controller 130, so that the driving motor 162 rotates after receiving the control instruction of the PLC controller 130, thereby driving the synchronous belt 163 to work and drive the optical fiber disc 160 to rotate, thereby providing a conveying power for the conveying of the optical fiber 200.

In this way, through the optical fiber length information displayed in real time on the display 170, the staff can control the guiding length of the optical fiber 200 in real time, so as to accurately cut the optical fiber 200 of the required length.

[0060] In this example, please continue to refer to Figure 4a The automatic fiber guiding device 100 provided in this embodiment may further include a power switch 191 , and the power switch 191 is electrically connected to the PLC controller 130 and the fiber cutting structure 140 .

[0061] In other embodiments, see Figure 4b , Figure 4b 1 is a right side view of the automatic fiber guiding device 100 provided in an embodiment of the present invention, as shown in FIG.

[0063] In order to better illustrate the working principle of the automatic fiber guiding device 100 provided by the embodiment of the present invention, the following will describe in detail the method of using the automatic fiber guiding device 100 provided by the present embodiment: First, turn on the power switch 191 of the automatic fiber guiding device to power on the device. At this time, the PLC controller 130 automatically starts up, and then checks whether the air pressure value of the filter pressure reducing valve is normal. If normal, operate the virtual button "Enable Off" on the display interface of the PLC controller 130 to allow the drive motor 162 to rotate freely manually. At this time, the fiber optic disc 160 can be installed on the automatic fiber guiding device 100, and the head end of the optical fiber 200 on the fiber optic disc 160 is inserted from the fiber inlet of the fiber guiding structure 150, and is pulled downward along the arc direction, and then passed out from the fiber outlet of the fiber guiding structure 150, and then the head end of the optical fiber 200 is continued to be inserted from the right end of the fiber cutting structure 140, and then passed out from its left end to expose the preset length of the optical fiber 200 suspended in the air. At this time, you can choose between the manual fiber cutting mode and the automatic fiber cutting mode:

[0064] Automatic fiber cutting mode: Press the virtual button "Auto" on the display interface of the PLC controller 130 to make the automatic fiber guiding device 100 enter the automatic mode, and then press the virtual button "XX meters" to set the optical fiber length to be cut, and then you can manually pull the optical fiber 200 from the left side. When pulling out the optical fiber 200, driven by friction, the encoder 141 in the fiber cutting structure 140 will generate a length signal (optical fiber length information) and transmit it to the PLC controller 130. The PLC controller 130 will then transmit the processed length signal to the display 170 to display the specific length value of the current optical fiber 200. When the required length value XX meters is reached, the PLC controller 130 issues a command to activate the solenoid valve 180, thereby controlling the pneumatic scissor head 142 in the fiber cutting structure 140 to perform the cutting action. At this time, the optical fiber 200 is cut at the pneumatic scissor head 142, and XX meters of optical fiber 200 can be obtained. After that, the operation can be cyclically performed in the automatic mode.

[0065] Manual fiber cutting mode: When you want to temporarily cut a section of optical fiber 200 of an uncommon length, you can use the manual fiber cutting mode of the automatic fiber guiding device 100 provided in this embodiment: press the virtual button "Enable On" on the display interface of the PLC controller 130, and at the same time press the virtual button "Release". At this time, the encoder 141 in the fiber cutting structure 140 can start counting, and then manually visually observe the optical fiber length value on the display 170. When the required optical fiber length is reached, press the virtual button "Cut Fiber". At this time, the PLC controller 130 issues a command to activate the solenoid valve 180, thereby controlling the pneumatic scissor head 142 to perform the cutting action. At this time, the optical fiber 200 is cut at the pneumatic scissor head 142, and a fixed-length optical fiber 200 can be obtained.
