Description

Technical Field

[0001] This utility model relates to the technical field of optical module production equipment, specifically to an anti-static dust removal device for cleaning optical modules. Background Technology

[0002] As a core optical component in data centers and communication equipment, the cleanliness of the interface face of optical modules directly affects the quality of optical signal transmission. Contamination such as dust and electrostatic adsorption can lead to increased insertion loss, higher bit error rate, and even permanent damage. Therefore, efficient and non-destructive cleaning in optical module maintenance has become a key technical aspect.

[0003] The existing patent publication number CN216500953U discloses a cleaning device for the end face of an optical module, which uses an electric pump to intermittently pump anhydrous ethanol in a cleaning dish to a sponge block, so that the sponge block always contains sufficient anhydrous ethanol, thereby ensuring the cleaning effect.

[0004] However, the sponge can only clean the outer surface of the optical module and cannot penetrate into the ferrule end face inside the interface. In actual use, dust and oil stains tend to accumulate in the interface ferrule area, causing the optical path to be blocked and the optical module interface to be unable to be cleaned, thus failing to meet the requirements. Therefore, there is an urgent need for an anti-static dust removal device for cleaning optical modules to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an anti-static dust removal device for cleaning optical modules, which has the advantages of efficient cleaning and static electricity elimination, and solves the problem that traditional optical module cleaning devices cannot clean the inside of the interface.

[0007] (II) Technical Solution

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An anti-static dust removal device for cleaning optical modules includes a workbench and an optical module placement frame. A cleaning table is fixedly installed on the top of the workbench. A sealing mechanism for isolating the closed space formed by the outside is provided on the top of the cleaning table. An anti-static mechanism for eliminating static electricity in the closed space is provided at the bottom of the cleaning table. A cleaning mechanism for cleaning the optical module interface is provided on the top of the cleaning table.

[0009] The cleaning mechanism includes a cleaning housing fixedly connected to the top of the cleaning table. An active roller is rotatably connected inside the cleaning housing. A cleaning port is opened on the side wall of the cleaning housing. A cleaning roller is rotatably connected to the inner side wall of the cleaning port. A cleaning belt is connected to the outside of the active roller and the cleaning roller for transmission. A first motor is fixedly installed on the side wall of the cleaning housing. A synchronizing rod is fixedly connected to the output shaft of the first motor. The synchronizing rod is fixedly connected to the active roller.

[0010] The beneficial effects of this utility model are:

[0011] This anti-static dust removal device for cleaning optical modules creates an isolated environment through a closed structure to avoid secondary pollution. The anti-static mechanism uses a plasma fan to neutralize static charges and prevent dust adsorption. The cleaning mechanism uses a flexible cleaning belt to contact the inside of the optical module interface, achieving precise dust removal and improving cleaning efficiency and reliability.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the static elimination mechanism includes a filter box fixedly installed on the top of the workbench. The cleaning table has two ventilation openings inside. One of the ventilation openings is fixedly connected to the filter box through a pipe. The filter box is fixedly connected to a plasma fan through a pipe. When the plasma fan is running, it generates plasma, which is transported to the other ventilation opening through the pipe.

[0014] The beneficial effects of adopting the above-mentioned further solutions are that the efficient ion airflow generated by the plasma fan actively neutralizes the static charge in the enclosed space, fundamentally avoiding secondary pollution caused by electrostatic adsorption of fine dust; the filter box can effectively filter out particulate impurities in the airflow, protect the plasma fan and extend its service life, and ensure the continuous and stable static elimination effect.

[0015] Furthermore, the sealing mechanism includes a sealing side plate fixedly connected to the top of the cleaning table, a guide slide fixedly connected to the top of the cleaning table, a fixed shell fixedly connected to the top of the cleaning table, and a sliding cover sleeved on the outside of the fixed shell slidably connected inside the guide slide.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the sliding cover slides along the guide slide, which together with the sealing side plate and the fixed shell forms a sealed operating space, effectively isolating dust and moisture in the external environment, providing a clean and stable working environment for cleaning the optical module, preventing secondary pollution during the cleaning process, and ensuring the consistency of cleaning quality.

[0017] Furthermore, a guide base is fixedly connected to the top of the cleaning platform, a second motor is fixedly installed on the side wall of the sealing side plate, a threaded rod is fixedly connected to the output shaft of the second motor, and a slide table is slidably connected to the external thread of the threaded rod inside the guide base. The optical module placement frame is fixedly installed on the top of the slide table and moves synchronously along the guide base with the slide table.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by driving the threaded rod with the second motor, the slide table and the optical module placement frame are moved precisely along the guide base, realizing the automated and precise positioning of the optical module interface relative to the cleaning belt. This not only improves cleaning efficiency, but also ensures that each optical module can be cleaned in the same optimal position, thereby improving the standardization and reliability of the cleaning operation.

[0019] Furthermore, the cleaning housing is rotatably connected to two guide rollers, the cleaning belt passes around the two guide rollers and extends to the bottom of the cleaning housing, and the top of the cleaning housing is fixedly connected to a feed pipe for adding cleaning liquid into the cleaning housing to wet the cleaning belt and improve the dust removal effect.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the two guide rollers change the transmission path of the cleaning belt, allowing it to effectively extend to the bottom of the cleaning housing. The feed pipe can drip cleaning liquid to keep the cleaning belt at a suitable humidity, thereby enhancing the ability to dissolve and remove stubborn stains, while reducing the potential damage to the end face of the optical module caused by drying friction.

[0021] Furthermore, there are several cleaning housings arranged in a horizontal array on the top of the cleaning table, and the active rollers of several cleaning housings are linked by a synchronization rod to achieve multi-station synchronous cleaning.

[0022] The advantage of adopting the above-mentioned further solution is that multiple cleaning housings are linked by a synchronizing rod, and only one first motor is needed to drive all cleaning belts to operate synchronously, thereby keeping the cleaning belts moist at all times.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the embodiments, by Figure 1-5 The present invention provides an anti-static dust removal device for cleaning optical modules. The present invention includes a workbench 1 and an optical module placement frame 3. A cleaning table 2 is fixedly mounted on the top of the workbench 1. A sealing mechanism for isolating the closed space formed by the outside world is provided on the top of the cleaning table 2. The sealing mechanism includes a sealing side plate 13 fixedly connected to the top of the cleaning table 2. A guide slide 14 is fixedly connected to the top of the cleaning table 2. A fixed shell 15 is fixedly connected to the top of the cleaning table 2. A sliding cover 16 sleeved on the outside of the fixed shell 15 is slidably connected inside the guide slide 14.

[0031] In this embodiment, in actual use, the top of the sliding cover 16 is fixedly connected to a handle, which makes it easy for people to push the sliding cover 16 along the guide slide 14 by manually pushing it. This allows the sliding cover 16, together with the sealing side plate 13 and the fixed shell 15, to form a sealed operating space, effectively isolating dust and moisture from the external environment, providing a clean and stable working environment for cleaning the optical module, preventing secondary pollution during the cleaning process, and ensuring the consistency of cleaning quality.

[0032] Specifically, refer to Figure 3 The bottom of the cleaning station 2 is equipped with an antistatic mechanism for eliminating static electricity in the enclosed space. The antistatic mechanism includes a filter box 11 fixedly installed on the top of the workbench 1. The cleaning station 2 has two ventilation openings 10 inside. One of the ventilation openings 10 is fixedly connected to the filter box 11 through a pipe. The filter box 11 is fixedly connected to a plasma fan 12 through a pipe. When the plasma fan 12 is running, it generates plasma, which is transported to the other ventilation opening 10 through a pipe.

[0033] In this embodiment, in actual use, the high-efficiency ion airflow generated by the plasma fan 12 actively neutralizes the static charge in the enclosed space, fundamentally avoiding secondary pollution caused by electrostatic adsorption of fine dust. The air inlet of the plasma fan 12 is connected to the filter box 11, so that the air in the enclosed space flows into the filter box 11 through the vent 10. The filter box 11 is equipped with a filter element. The filter element material is a combination of a high-efficiency HEPA filter and an activated carbon layer. The HEPA filter is used to capture particulate matter in the airflow, and the activated carbon layer adsorbs volatile organic compounds and odors, ensuring that the airflow entering the plasma fan 12 is clean, extending the fan's lifespan and improving the stability of static elimination, protecting the plasma fan 12 and extending its service life, and ensuring the continuous and stable effect of static elimination.

[0034] Specifically, refer to Figure 4 The top of the cleaning platform 2 is equipped with a cleaning mechanism for cleaning the optical module interface. The cleaning mechanism includes a cleaning housing 4 fixedly connected to the top of the cleaning platform 2. An active roller 5 is rotatably connected inside the cleaning housing 4. A cleaning port is opened on the side wall of the cleaning housing 4. A cleaning roller 6 is rotatably connected to the inner side wall of the cleaning port. A cleaning belt 7 is connected to the outside of the active roller 5 and the cleaning roller 6 for transmission. A first motor 8 is fixedly installed on the side wall of the cleaning housing 4. A synchronizing rod 9 is fixedly connected to the output shaft of the first motor 8. The synchronizing rod 9 is fixedly connected to the active roller 5.

[0035] Specifically, refer to Figure 5 The cleaning housing 4 has two guide rollers 21 rotatably connected inside. The cleaning belt 7 passes around the two guide rollers 21 and extends to the bottom of the cleaning housing 4. The top of the cleaning housing 4 is fixedly connected to a feed pipe for adding cleaning liquid into the cleaning housing 4 to wet the cleaning belt 7 and improve the dust removal effect. There are several cleaning housings 4, which are arranged in a horizontal array on the top of the cleaning table 2. The drive rollers 5 of several cleaning housings 4 are linked by a synchronization rod 9 to realize multi-station synchronous cleaning. Multiple cleaning housings 4 are linked by a synchronization rod 9, and only one first motor 8 is needed to drive all cleaning belts 7 to operate synchronously.

[0036] In this embodiment, in actual use, the two guide rollers 21 change the transmission path of the cleaning belt 7, so that it can effectively extend to the bottom of the cleaning housing 4. The feed pipe can drip cleaning liquid to keep the cleaning belt 7 at a suitable humidity, thereby enhancing the ability to dissolve and remove stubborn stains, while reducing the potential damage to the end face of the optical module caused by drying friction.

[0037] The cleaning belt 7 wears out during use and needs to be replaced periodically. To replace it, locate the joints between the beginning and end of the cleaning belt 7 on the cleaning roller 6, separate them, and attach a new cleaning belt 7. The first motor 8 drives the synchronizing rod 9 to rotate the drive roller 5, causing the old cleaning belt 7 to move the new cleaning belt 7 into the cleaning housing 4. After the replacement is complete, remove the old cleaning belt 7 and attach the new cleaning belt 7 end to end to complete the replacement.

[0038] Specifically, refer to Figure 4 A guide base 17 is fixedly connected to the top of the cleaning table 2. A second motor 18 is fixedly installed on the side wall of the sealing side plate 13. A threaded rod 19 is fixedly connected to the output shaft of the second motor 18. A slide table 20 is slidably connected to the outside of the threaded rod 19 and is connected to the inside of the guide base 17. The optical module placement frame 3 is fixedly installed on the top of the slide table 20 and moves synchronously along the guide base 17 with the slide table 20.

[0039] In this embodiment, in actual use, the second motor 18 drives the threaded rod 19, which in turn drives the slide table 20 and the optical module placement frame 3 to move precisely along the guide base 17. This achieves automated and precise positioning of the optical module interface relative to the cleaning belt 7, which not only improves cleaning efficiency but also ensures that each optical module can be cleaned in the same optimal position, thereby enhancing the standardization and reliability of the cleaning operation.

[0040] Working principle:

[0041] The operator places the optical module to be cleaned on the optical module placement frame 3, and manually pushes the sliding cover 16 along the guide slide 14 to close the sliding cover 16 with the sealing side plate 13 and the fixed shell 15, forming a sealed operating space. The plasma fan 12 is started, generating an airflow rich in positive and negative ions. The airflow enters the sealed space through a duct from a vent 10, neutralizes the static charge on the surface of the optical module and the cleaning belt 7, and then flows back to the filter box 11 through another vent 10. The HEPA filter and activated carbon layer in the filter box 11 filter out particulate pollutants in the airflow, and the purified air is recirculated to continuously eliminate static electricity.

[0042] The second motor 18 is started via the control panel, driving the threaded rod 19 to rotate and causing the slide table 20 to move along the guide base 17, so that one end of the cleaning housing 4 is inserted into the interface of the optical module. The first motor 8 is started, driving all the active rollers 5 of the cleaning housing 4 to rotate synchronously via the synchronizing rod 9, causing the cleaning belt 7 to continuously rotate around the cleaning roller 6 and the guide roller 21. At the same time, ethanol is applied to the surface of the cleaning belt 7 to wet it. The optical module interface comes into contact with the cleaning belt 7, and the wet cleaning belt 7 dissolves and wipes the stains on the end face of the interface core. After cleaning is completed, the first motor 8 stops, and the second motor 18 drives the slide table 20 in the opposite direction to return to the initial position. The sliding cover 16 is opened, and the operator inserts the sealing cover into the optical module interface.
