Description

Technical Field

[0001] This utility model relates to the field of optical fiber ferrule cleaning technology, specifically to an MPO ferrule cleaning device. Background Technology

[0002] In the field of optical fiber communication, especially in data centers, high-performance computing networks, and 5G bearer networks, MPO multi-core fiber optic connectors are widely used due to their high density and high efficiency. A standard MPO connector can accommodate 12, 24, or even more optical fibers, and the cleanliness of its ferrule end face directly determines the transmission quality of the optical signal.

[0003] Currently, cleaning the end face of MPO ferrules mainly relies on manual dry cleaning. Operators use specialized MPO cleaning pens or tweezers, employing internal adhesive rollers or wiping strips to mechanically scrape and adhere contaminants. While this method can clean the MPO ferrule end face to some extent, it has significant drawbacks: First, the cleaning effect is highly dependent on the operator's technique, resulting in poor repeatability and a risk of scratching the delicate ceramic ferrule due to improper operation. Second, the removed contaminants may detach from the cleaning tools and remain inside the interface or in the air, causing secondary contamination. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an MPO ferrule cleaning device that solves the problems of low cleaning efficiency and secondary pollution that are common in existing MPO ferrule cleaning technologies.

[0005] According to an embodiment of the present invention, an MPO ferrule cleaning device includes: Equipment box; A cleaning box having a cleaning chamber extending through the end of the cleaning box to form an opening for installing the insert; An airflow distributor is located in the equipment box and is equipped with at least one auxiliary airflow pipe, the end of which extends into the cleaning chamber. The vacuum generator and solenoid valve are both located in the equipment box. The solenoid valve is connected to the airflow distributor and the vacuum generator through the main air blowing pipe. The vacuum generator is equipped with a suction pipe, which is located in the equipment box and extends into the cleaning chamber.

[0006] Preferably, the end of the cleaning box is detachably provided with a mounting block, and the mounting block has a mounting hole for installing the insert.

[0007] Preferably, both the mounting block and the cleaning box have multiple assembly holes at their ends, with each assembly hole on the mounting block corresponding to one assembly hole on the cleaning box.

[0008] Preferably, there are four auxiliary air blowing pipes, and the four auxiliary air blowing pipes are respectively installed on multiple different sides of the cleaning box.

[0009] Preferably, the side of the equipment box has several through holes corresponding to the air inlet of the solenoid valve and the exhaust port of the vacuum generator.

[0010] Preferably, a filter element is provided in the through hole corresponding to the exhaust port of the vacuum generator.

[0011] Preferably, it also includes a sensor, which is located in the cleaning chamber.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This solution highly integrates airflow distribution, blowing, and suction modules into the equipment box and cleaning box. Compressed air is used as the cleaning medium and has no physical contact with the MPO ferrule end face, avoiding the risk of scratching or damaging the precision ceramic ferrule due to mechanical scraping. Moreover, with the linkage of the vacuum generator and solenoid valve, the entire blowing and suction process is automated.

[0017] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] This invention provides an MPO ferrule cleaning device, comprising: Equipment box 1; Cleaning box 2, the cleaning box 2 has a cleaning cavity 201 extending through the end of the cleaning box 2 to form an opening for installing the insert; Airflow distributor 5 is located in equipment box 1 and is equipped with at least one auxiliary air blowing pipe 501. The end of the auxiliary air blowing pipe 501 extends into the cleaning chamber 201. Vacuum generator 4 and solenoid valve 7 are both located in equipment box 1. Solenoid valve 7 is connected to airflow distributor 5 and vacuum generator 4 through main air blowing pipe 701. Vacuum generator 4 is equipped with suction pipe 401, which is located in equipment box 1 and extends into the cleaning chamber 201.

[0019] In this embodiment, as Figures 1 to 3 As shown, the airflow distributor 5, vacuum generator 4 and solenoid valve 7 are all integrated in the equipment box 1. The equipment box 1 is a closed box structure, which can prevent external contamination of the various devices of the equipment.

[0020] The solenoid valve 7 has an air inlet and at least two air outlets, which are conventional accessories in the prior art. The solenoid valve 7 is used as an air filling accessory. The air inlet is connected to a compressed gas source. After the solenoid valve 7 releases the pressurized gas, one of the air outlets of the solenoid valve 7 is connected to the air distribution device 5 through a main air blowing pipe 701 to provide an air source for cleaning. The other air outlet is connected to the air supply port of the vacuum generator (4) through another main air blowing pipe 701 to provide power for generating a vacuum. The air distribution device 5 delivers the airflow to the cleaning chamber 201 through the auxiliary air blowing pipe 501 to blow clean the MPO insert end that has been inserted into the cleaning chamber 201. At the same time, compressed air enters the air supply port of the vacuum generator 4. The vacuum port of the vacuum generator 4 is connected to the cleaning chamber 201 through the suction pipe 401, which can quickly push the cleaned impurities to the low-pressure area and realize the function of air extraction.

[0021] Secondly, the cleaning device also includes a sensor 6, which is located in the cleaning chamber 201. The sensor 6 consists of two parts: its signal receiving end is installed inside the equipment box 1, and its detection end is installed in the cleaning chamber 201. The sensor 6 can be a micro switch. When the MPO insert is inserted and touches the detection end of the micro switch, the detection end of the micro switch sends a signal to trigger the solenoid valve 7 and the vacuum generator 4 to start synchronously, thereby realizing automated cleaning.

[0022] This device highly integrates airflow distribution, blowing, and suction modules into equipment box 1 and cleaning box 2. Compressed air is used as the cleaning medium and has no physical contact with the MPO ferrule end face, avoiding the risk of scratching or damaging the precision ceramic ferrule due to mechanical scraping. Moreover, with the linkage of vacuum generator 4 and solenoid valve 7, the entire blowing and suction process is automated. Each operation executes the same cleaning process with the same intensity and duration, ensuring the consistency and repeatability of the cleaning effect. It is suitable for batch operations and has high efficiency.

[0023] A single auxiliary air pipe 501 can only blow air from one direction. For the grooves, holes and back areas blocked by pins on the MPO ferrule end face that are parallel to the airflow direction, the cleaning effect is limited. In order to achieve comprehensive cleaning of the MPO ferrule end face, specifically, there are four auxiliary air pipes 501, and the four auxiliary air pipes 501 are respectively installed on multiple different sides of the cleaning box 2. The multiple auxiliary air pipes 501 wrap around the ferrule end face from various angles, blowing away dust from all directions and improving the cleaning quality.

[0024] Specifically, such as Figure 1 As shown, different MPO connectors (such as 8-pin, 12-pin, 24-pin) or similar connectors from different manufacturers may have slight differences in their external dimensions, positioning key positions, or locking mechanisms. The end of the cleaning box 2 is detachably equipped with a mounting block 3. The mounting block 3 has mounting holes 301 for mounting the ferrule. By replacing different specifications of the mounting block 3, the mounting holes 301 on each mounting block 3 can be precisely matched with a specific model of ferrule, which can achieve cleaning of connectors of different specifications.

[0025] The detachable connection of the mounting block 3 can be a snap-fit, preferably a bolt connection. Both the mounting block 3 and the cleaning box 2 have multiple assembly holes 302 at their ends. Each assembly hole 302 of the mounting block 3 corresponds to each assembly hole 302 of the cleaning box 2. When the mounting block 3 is mated to the end of the cleaning box 2, it can be installed between two corresponding assembly holes 302 by bolts, thus ensuring the installation strength of the mounting block 3.

[0026] Specifically, such as Figure 2 As shown, the side of the equipment box 1 has several through holes 101 corresponding to the air inlet of the solenoid valve 7 and the exhaust port of the vacuum generator 4. Each through hole 101 corresponding to the solenoid valve 7 ensures the normal input of standard compressed air to the solenoid valve 7, and the through hole 101 corresponding to the vacuum generator 4 ensures the normal exhaust of the vacuum generator 4. At the same time, the through hole 101 corresponding to the exhaust port of the vacuum generator 4 is equipped with a filter element 102. The exhaust port of the vacuum generator 4 not only discharges the clean compressed air that drives it, but also discharges the dusty air drawn up from the cleaning chamber 201. The filter element 102 can completely intercept solid particles in the exhaust and avoid environmental pollution.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
