[0025] like Figure 1 and Figure 2 As shown, the optical fiber interface end face cleaning device includes a shell, which includes a middle shell 101, a left cover 102 and a right cover 103. A partition 1011 is provided in the middle shell 101, and the partition 1011 divides the internal space of the middle shell 101 into a left accommodating portion and a right accommodating portion. The left cover 102 is used to cover the left accommodating portion, and the right cover 103 is used to cover the right accommodating portion.

[0026] The right accommodating part of the housing is provided with a cassette box 200, and a cleaning belt 201 is provided on the cassette box 200. The cleaning belt 201 is a cloth strip. The cleaning belt 201 is movable and can be driven by a motor. After the optical fiber connector is installed on the cleaning device, the cleaning belt 201 contacts the end face of the optical fiber interface. The cleaning belt 201 rubs the end face of the optical fiber interface when moving, thereby cleaning the end face of the optical fiber interface.

[0027] like Figures 2 to 4 As shown, a box body 300 and a sprayer 400 are also provided in the shell. The box body 300 is installed in the left accommodating portion. Cleaning liquid or water is filled in the box body 300. The box body 300 is connected to the sprayer 400. The sprayer 400 is arranged at a position opposite to the cleaning belt 201, and the cleaning liquid or water is sprayed on the cleaning belt by the sprayer 400. The end face of the optical fiber connector is rubbed with the part sprayed with the cleaning liquid or water to wipe off the dirt, so that the cleaning belt can wet clean the end face of the optical fiber interface, and the cleaning effect on stubborn dirt is better.

[0028] The box body 300 is connected to the sprayer 400 through a pipe 302. The partition plate 1011 is provided with a through hole 10111 for the pipe 302 to pass through. The sprayer 400 is located in the right receiving portion. A blocking cover 401 covering the outside of the sprayer is installed in the right receiving portion.

[0029] like Figure 2 and Figure 5 As shown, a sensor 301 is provided at the bottom of the box 300, and the liquid level in the box 300 is monitored by the sensor 301. When the liquid level in the box drops to the sensing point of the sensor, the cleaning device will alarm and automatically stop cleaning, so that it can be obtained in real time whether the water in the box is exhausted.

[0030] The box body 300 is supported by a transparent material, and a window 1012 for observing the liquid level in the box body 300 is provided on the middle shell 101 of the shell. A liquid level observation window is provided on the front of the shell, and the user can observe the liquid level in the box body in real time through the window. A water inlet 303 is provided on the top of the box body 300.

[0031] like Figure 1 As shown, the housing is provided with a function selection button 110, through which the dry mode or the wet mode is selected for cleaning. When the dry mode is selected, the device only performs conventional cleaning, that is, the motor drives the clean cleaning cloth strip in the cleaning belt to rub against the end face of the optical fiber connector in the same direction for a certain distance, thereby wiping off the dirt on the end face of the optical fiber connector. When the wet mode is selected, the device sprays the clean cleaning cloth strip in the cleaning belt with cleaning liquid or water through the sprayer at the bottom of the box to humidify it. After a certain period of time, the motor drives the humidified cleaning cloth strip in the cleaning belt to rub against the end face of the optical fiber connector in the same direction for a certain distance, thereby wiping off the dirt on the end face of the optical fiber connector.

[0032] like Figure 2 As shown, the right side cover 103 is detachably mounted on the middle shell 101. By removing the right side cover of the device, the cassette box can be replaced, and the service life and life of the device can be extended by replacing a clean cleaning tape.

[0033] In this embodiment, the right side cover 103 is snap-connected with the middle shell 101, the upper and lower edges of the right side cover are provided with buckles, the upper and lower edges of the right receiving portion of the middle shell are provided with slots that cooperate with the buckles, and the buckles cooperate with the slots to fix the right side cover 103 on the middle shell 101. When the right side cover needs to be removed, just slide the right side cover upwards to separate the right side cover from the middle shell.

[0034] like Figure 1 , Figure 2 and Figure 5 As shown, the cleaning device of the utility model further includes a connector adapter 500 and a PAD module 600. A socket 1013 is provided on the middle shell 101. The connector adapter 500 is detachably installed in the socket 1013. A pin 1014 is provided inside the socket 1013. The pin 1014 contacts the conductive sheet on the connector adapter 500. The PAD module 600 is provided obliquely below the connector adapter 500. After the connector adapter 500 is installed, the cleaning tape is located between the connector adapter 500 and the PAD module 600. After the optical fiber connector 1 is plugged into the connector adapter 500, the ferrule of the connector adapter 500 will squeeze the PAD module 600.

[0035] Since the connector adapter is detachably installed in the socket, the cleaning device can be switched to different types of cleaning states by replacing the adapter at the cleaning port. When you need to clean a certain type of fiber optic interface, just choose to replace it with the corresponding adapter. Currently, the cleaning device can clean the surface dirt of nine different types of fiber optic interfaces, namely connectors (PC and APC), SC connectors (PC and APC), duplex LC connectors (PC and APC), 1.25 ferrules (PC and APC), 2.5 ferrules (PC and APC), MT (PC), MT (APC), MPO (PC), MPO (APC). Users can switch arbitrarily according to their needs.

[0036] Since the PAD module is provided, the cleaning device can realize automatic induction cleaning through the PAD module. The PAD module contains springs and pressure sensors inside, which can sense the pressure applied to the PAD module in real time and give ADC value data feedback, thereby triggering cleaning. The force applied to the pressure sensor is obtained by the pressure of the silicone pad pressed by the optical fiber connector on the PAD module. The magnitude of the pressure is transmitted to the pressure sensor through the internal spring for numerical feedback. A value for starting cleaning is set based on the principle that the greater the force applied to the PAD module, the greater the force sensed by the pressure sensor, and the greater the ADC value. When the pressure applied to the PAD module reaches or reaches the set value, cleaning can be started. The magnitude of the pressure is determined by the depth of the optical fiber connector pressed into the PAD module, and the depth of the optical fiber connector pressed into the PAD module is limited by the adapter.

[0037] When different types of adapters are inserted, the cleaning device can automatically identify and enter the cleaning state corresponding to the adapter type (using permutations and combinations) by performing different conduction sequences or numbers of ejectors between the ejector pins and the metal conductive sheet on the adapter.

[0038] This application is an improvement on Seiko Giken's desktop cleaning machine. Seiko Giken's product patent discloses the cassette box, cassette, adapter, PAD module and its cleaning principle. The utility model of this application is to achieve wet cleaning by setting up a box and a sprayer, which has a better cleaning effect on stubborn dirt.

[0039] like Figure 6 and Figure 7 As shown, the utility model controls different sensors on the device through a single-chip microcomputer chip. In different usage scenarios, the logic is realized through the process to trigger the functions of different sensors.

[0040] refer to Figure 6The single-chip microcomputer (MCU) controls the stepper motor, buttons, USB interface, screen, fixture chip select sensor, cleaning belt sensor, pressure sensor, ultrasonic sensor, and liquid level sensor in the box.
