Description

Technical Field

[0001] The present invention relates to the technical field of ceramic ferrule end face detection equipment, in particular to a detection device and a cleaning system for a ceramic ferrule end face. Background Art

[0002] ODN is the abbreviation of Optical Distribution Network, which is a distributed optical fiber network that can transmit optical signals to different user terminals. ODN can support a variety of services such as broadband access, indoor and outdoor wireless access, and enterprise network access, which can greatly improve the speed and reliability of the network. As an important part of transmitting split optical signals in the ODN system, the ceramic ferrule of the connecting device plays a key role in connecting the upper and lower parts. The end face of the ceramic ferrule plays a vital role in the high-speed transmission of signals. Only by ensuring the cleanliness of the end face can the stable and high-speed transmission of signals be guaranteed.

[0003] A ceramic ferrule assembly usually includes a fiber core and a shell. After the ceramic ferrule assembly is processed, the end face of the ceramic ferrule assembly needs to be inspected. The prior art usually manually takes the ceramic ferrule assembly to be inspected and places it on a detection platform, and then manually focuses and manually observes the fiber core end face and the ceramic end face of the shell. The entire detection process is all done manually, which is inefficient and prone to large operating errors.

[0004] For example, a ceramic ferrule assembly end face detection machine with publication number CN217505673U includes: a machine platform; a loading and unloading assembly, which is arranged on the machine platform; a core end face detection mechanism and a ceramic surface detection mechanism, which are both arranged on the machine platform; by arranging the loading and unloading assembly, the loading mechanism, the core end face detection mechanism and the ceramic surface detection mechanism, automatic loading and unloading and automatic transfer of the ceramic ferrule assembly are realized, and automatic detection of the end face appearance of the ceramic ferrule assembly is completed, which effectively reduces the difficulty of detection operation, improves detection efficiency, and avoids the interference of manual operation errors with the detection results, thereby effectively improving the end face detection accuracy.

[0005] Although the above patent can automatically clean and inspect the ceramic ferrule, the movement of the ceramic ferrule always needs to be carried out by a robotic arm. During the transportation process of the ceramic ferrule, it is possible to be contaminated again, affecting the detection structure.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. This device uses a clean bench mechanism, a plasma fan, and an intelligent integrated optical fiber end face detector to keep the ceramic ferrule end face clean for a long time. It is finally installed in the engineering communication system to ensure high-speed and stable signal transmission. At the same time, automated equipment is used to automatically inspect and confirm the end face of the ceramic ferrule to avoid human errors, improve production efficiency, ensure end face yield, ensure product quality, and solve the problem of possible re-contamination during the transportation of the ceramic ferrule.

[0026] 2. Before inspecting the end face of the ceramic ferrule, the ultraviolet lamp is used to irradiate the inside of the workbench to ensure its sterilization effect and achieve self-cleaning of the working area. After the end, turn off the ultraviolet lamp, turn on the lighting and air filter, keep the wind speed running at a slow speed, allow the air to circulate, then turn on the plasma fan, adjust the wind speed gear, and align the air outlet with the fixing mechanism, which has a good sterilization effect on the inspection of the ceramic ferrule end face.

[0027] 3. The mechanical arm drives the ceramic ferrule to translate and insert it into the connecting tube. The air pump is turned on. High-speed gas is ejected through the air pipe and sprayed on the ceramic ferrule, which can blow away the dust and oil stains on the surface of the ceramic ferrule to achieve the effect of cleaning the end face and ensure the accuracy of the ceramic ferrule detection results. During the cleaning process, the spiral blades, inner cylinder, bellows, and connecting tube rotate, so that the gas is evenly sprayed on the ceramic ferrule, and the cleaning is more comprehensive.

[0028] 4. After the second water pump is turned on, the cleaning liquid is sprayed out from the atomizing nozzle. When the avoidance hole is rotated to be connected with the outlet of the atomizing nozzle, the cleaning liquid will be sprayed on the ceramic ferrule through the avoidance hole. When the avoidance hole is rotated to be misaligned with the outlet of the atomizing nozzle, the cleaning liquid will not be sprayed out. Therefore, intermittent liquid spraying occurs, which is convenient for cleaning the ceramic ferrule multiple times. The cleaned liquid flows out from the dust outlet hole of the inner cylinder and can be re-extracted into the first cylinder by the first water pump for utilization, thereby saving energy.

[0029] 5. Through the coordination between the gas cleaning component and the liquid cleaning component, the two can be controlled separately and started at the same time, which can not only ensure the cleanliness of the end face of the ceramic ferrule, but also keep the end face clean for a long time, thus ensuring the end face yield and product quality.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figure 1-Figure 5 The present invention provides a technical solution: a detection device for the end face of a ceramic ferrule, comprising an ultra-clean bench mechanism 1, a control mechanism 2 is fixedly installed on the upper end of the ultra-clean bench mechanism 1, and the control mechanism 2 is electrically connected to the ultra-clean bench mechanism 1 and the internal components of the ultra-clean bench mechanism 1, and is used to open, close and adjust the entire device.

[0042] The clean bench mechanism 1 includes an outer frame 11 , with glass windows 12 inlaid on both sides of the outer frame 11 . When the ceramic ferrule is inspected, the glass windows 12 are in a visible state, which is convenient for operators to visually monitor the ceramic ferrule so as to use the control mechanism 2 for control and adjustment.

[0043] An air filter 17 is installed on the top of the outer frame 11. The air outlet of the air filter 17 is set at the upper end of the outer frame 11. When it is turned on, the clean air flow blown out from the air outlet has a certain and uniform cross-sectional wind speed, which can remove the original air in the working area of ​​the clean bench mechanism 1 and take away dust particles and biological particles to form a sterile and highly clean working environment, providing a clean working environment for end face inspection.

[0044] A push-pull mechanism 3 is installed on one side of the clean bench mechanism 1. The push-pull mechanism 3 is installed on one side of the clean bench mechanism 1 to control the opening and closing of the clean bench mechanism 1, thereby ensuring that the end face of the ceramic ferrule is inspected in a clean space.

[0045] A fixing mechanism 5 is installed in the clean bench mechanism 1, and the fixing mechanism 5 is used to fix the position of the ceramic ferrule during the detection process.

[0046] A back hole 19 is opened at the back of the outer frame 11, and a static electricity removal mechanism 4 is installed at the back end of the clean bench mechanism 1. The static electricity removal mechanism 4 includes a back plate 41 arranged at the back end of the outer frame 11, and a plasma fan 42 is embedded on the back plate 41. The plasma fan 42 is located in the back hole 19.

[0047] When the surface of the ceramic ferrule carries electrostatic charge, the plasma fan 42 generates an airflow containing a large number of positive ions and negative ions. These ions will be attracted to objects with opposite charges, thereby neutralizing the charge on the ceramic ferrule. If the surface of the ceramic ferrule carries a negative charge, it will absorb the positive ions in the airflow; if the surface of the ceramic ferrule carries a positive charge, it will absorb the negative ions in the airflow. In this way, the plasma fan 42 can effectively eliminate the static electricity on the surface of the ceramic ferrule.

[0048] A second slide groove 18 is provided at the back end of the outer frame 11, and a slider 43 is fixedly installed on the back plate 41. The slider 43 is slidably installed in the second slide groove 18. Through the cooperation of the back plate 41, the slider 43 and the second slide groove 18, the back plate 41 can drive the plasma fan 42 to move on the back of the outer frame 11. No matter where the back plate 41 moves to, the plasma fan 42 is always located in the back hole 19 and is always located on one side of the ceramic ferrule during the detection process, which can eliminate static electricity on the surface of the ceramic ferrule at all times.

[0049] A detection mechanism 6 is also installed in the clean bench mechanism 1. The detection mechanism 6 includes an optical fiber end face detector 61. A detection port 62 is set on one side of the optical fiber end face detector 61. The optical fiber end face detector 61 performs optical detection through an amplifier and an extended end face focusing mirror constituting a sensor. When the switch of the intelligent integrated optical fiber end face detector 61 is turned on, the software will automatically enter the main interface. One end of the ceramic ferrule can be inserted into the detection port 62. The operator manually adjusts the X and Y axis image adjustment screws to make the observed object in the middle of the display screen, and then adjusts the embracing focus ring so that the image can be clearly displayed. The green value displayed on the optical fiber end face detector 61 indicates pass, and the red value indicates fail. Repeat the above steps to test. After the end face inspection is qualified, put on a clean dust cap and then flow to the next process.

[0050] The device uses a clean bench mechanism 1, a plasma fan 42, and an intelligent integrated optical fiber end face detector 61 to work together, so that the end face of the ceramic ferrule can be kept clean for a long time, and finally installed in the engineering communication system to ensure high speed and stability of signal transmission. At the same time, automated equipment is used to automatically inspect and confirm the end face of the ceramic ferrule to avoid human judgment errors, improve production efficiency, ensure end face yield, and ensure product quality.

[0051] Example 2: Please refer to Figure 2-Figure 5 The clean bench mechanism 1 also includes a material storage box 13 installed at the lower end of the outer frame 11, and a working plate 14 is fixedly installed at the upper end of the material storage box 13. The working plate 14 is provided with a through hole 15 connected to the material storage box 13. The liquid generated inside the clean bench mechanism 1 can be discharged through the through hole 15 and finally stored in the material storage box 13, so as to avoid the long-term accumulation of dust or liquid inside the clean bench mechanism 1.

[0052] The control mechanism 2 includes a support frame 21, which is fixedly mounted on the upper end of the outer frame 11. A mounting hole 22 is opened in the middle of the support frame 21, and the air filter 17 is installed in the mounting hole 22. A control panel 23 is installed on one side of the support frame 21. The air filter 17, the plasma fan 42, and the optical fiber end face detector 61 are all electrically connected to the control panel 23. The control panel 23 can be opened, closed, and adjusted without the operator's hand reaching into the clean bench mechanism 1 for control and adjustment, which is convenient for control outside the workbench, further reducing the entry of dust during the detection process.

[0053] A first slide groove 16 is provided on both sides of the outer frame 11, and the push-pull mechanism 3 includes a central axis 31 fixedly installed on the upper end of the first slide groove 16, and a flexible shielding curtain 32 is fixedly installed on the outside of the central axis 31. The flexible shielding curtain 32 is wrapped around the central axis 31, and an ultraviolet lamp 33 is fixedly installed on the lower end of the flexible shielding curtain 32. When the ultraviolet lamp 33 is turned on, the surrounding environment can be sterilized. The side wall of the flexible shielding curtain 32 is inlaid with a light 34. When the light 34 is turned on, the surrounding environment can be illuminated.

[0054] Before inspecting the end face of the ceramic ferrule, first pull down the flexible shielding curtain 32 and turn on the ultraviolet lamp 33. The ultraviolet lamp 33 irradiates the inside of the workbench and keeps the flexible shielding curtain 32 in a semi-closed state for 10 minutes to ensure its sterilization effect and realize self-cleaning of the working area. After the inspection, turn off the ultraviolet lamp 33, turn on the lighting light 34 and the air filter 17, keep the wind speed running in a slow state, and circulate the air. Then turn on the plasma fan 42, adjust the wind speed gear, and align the air outlet with the fixing mechanism 5, so as to achieve a good sterilization effect for the inspection of the end face of the ceramic ferrule.

[0055] The fixing mechanism 5 includes a fixing plate 51 fixedly mounted on the working plate 14, a mechanical arm 52 fixedly mounted on the upper end of the fixing plate 51, a rotating block 53 rotatably mounted on the upper end of the mechanical arm 52, an arc plate 54 fixedly mounted on the upper end of the rotating block 53, and a plurality of protrusions 55 fixedly mounted on the arc plate 54.

[0056] After the preparation work is completed, the ceramic ferrule can be installed on the arc plate 54, and the protrusions 55 press the two sides of the ceramic ferrule. By adjusting the movement trajectory of the mechanical arm 52, the ceramic ferrule can be inserted into the detection port 62 of the optical fiber end face detector 61. The whole process does not require manual operation and is in a dust-free and clean environment, ensuring the accuracy of the inspection data and the convenience of operation.

[0057] Example 3: Please refer to Figure 6-Figure 8The present invention also discloses a cleaning system for a ceramic end face in a detection device for a ceramic ferrule end face, including a cleaning mechanism 7 for cleaning the ceramic ferrule end face, the cleaning mechanism 7 is installed in a clean bench mechanism 1, the cleaning mechanism 7 includes an outer shell 71, the outer shell 71 is arranged on a side of the ceramic ferrule away from the optical fiber end face detector 61, and is also fixedly installed on the upper end of a fixing plate 51, two support plates 72 are fixedly installed inside the outer shell 71, one of the support plates 72 and the outer shell 71 can enclose a rectangular space, a filter 75 is installed in the middle of the space, a cleaning liquid and a first water pump 76 are stored in the space, and a connecting pipe 77 is connected to one side of the first water pump 76. After the first water pump 76 is turned on, the cleaning liquid inside the space can be extracted and used as the cleaning liquid for the ceramic ferrule.

[0058] A connecting mechanism 74 is provided on one side of the outer shell 71, and the connecting mechanism 74 includes a connecting pipe 741 which is inserted and connected with the outer shell 71, an overflow hole 742 is provided on one side of the connecting pipe 741, and the overflow hole 742 is provided at the upper end of the filter element 75, a bellows 743 is fixedly installed inside the connecting pipe 741, and an inner cylinder 744 is connected and installed on one side of the bellows 743, a sieve plate 745 is fixedly installed on one end of the inner cylinder 744, a rotating plate 746 is fixedly installed on the outer periphery of the inner cylinder 744, a baffle 7461 is installed on one end of the rotating plate 746, a spiral blade 747 is fixedly installed on one end of the rotating plate 746, a dust outlet hole 748 is provided on the outer periphery of the inner cylinder 744, and an air outlet hole 749 is provided on the rotating plate 746.

[0059] A gas cleaning assembly 8 is disposed inside the outer shell 71 . The gas cleaning assembly 8 includes an air pump 81 . An air pipe 82 is installed on one side of the air pump 81 .

[0060] The ceramic ferrule is mounted on the arc plate 54, and the mechanical arm 52 drives the ceramic ferrule to translate so that it is inserted into the connecting tube 741. One end of the ceramic ferrule passes through the bellows 743 and rests against the sieve plate 745. The air pump 81 is turned on, and high-speed gas is ejected through the air pipe 82, passes through the air outlet hole 749 on the rotating plate 746 and the dust outlet hole 748 of the inner cylinder 744, and sprayed on the ceramic ferrule, which can blow away the dust and oil stains on the surface of the ceramic ferrule to achieve the effect of cleaning the end face and ensure the accuracy of the ceramic ferrule detection result.

[0061] The high-pressure gas ejected from the air pipe 82 is also sprayed onto the spiral blade 747, driving the spiral blade 747, the rotating plate 746, the sieve plate 745, the inner cylinder 744, the bellows 743, and the connecting pipe 741 to rotate. During the rotation of the sieve plate 745, the gas can be disturbed so that the gas is evenly sprayed on the ceramic ferrule, which cleans it more comprehensively. During the rotation, the bellows 743 can rub against the outer periphery of the ceramic ferrule for secondary cleaning.

[0062] After cleaning, the inner cylinder 744 and one end of the connecting tube 741 are both conical structures. With the centrifugal force generated by the rotating airflow, the dust will slide out along the inclined surface of the conical structure and finally be discharged from the dust outlet hole 748 of the inner cylinder 744. It will not be brought out of the connecting tube 741 by the ceramic insert, thereby further ensuring the cleanliness of the ceramic insert.

[0063] The mechanical arm 52 draws the ceramic ferrule out of the connecting tube 741 , and the bellows 743 rubs the ceramic ferrule, further preventing dust from being brought out of the connecting tube 741 , resulting in a good use effect.

[0064] Example 4: Please refer to Figure 6-Figure 9 A liquid cleaning component 9 is arranged inside the outer shell 71, and the liquid cleaning component 9 includes a first cylinder 91 arranged inside the outer shell 71, a second cylinder 92 is arranged inside the first cylinder 91, a second water pump 93 is arranged inside the second cylinder 92, one end of the second cylinder 92 is connected to the third cylinder 94, a fixing ring 95 is fixedly installed on the inner wall of the first cylinder 91, the third cylinder 94 is slidably installed in the fixing ring 95, one end of the third cylinder 94 is rotatably connected to the inner cylinder 744, the third cylinder 94 also rotates inside the spiral blade 747, one end of the third cylinder 94 is installed with an atomizing nozzle 96, and an elastic member 97 is installed between the fixing ring 95 and the second cylinder 92.

[0065] A liquid inlet 98 is provided on both the first cylinder 91 and the second cylinder 92 , and the liquid inlet 98 is connected to the connecting pipe 77 . An air inlet 99 is provided at the lower end of the first cylinder 91 , and the air inlet 99 is arranged at the lower end of the spiral blade 747 and is also connected to the air pipe 82 .

[0066] Cleaning liquid is arranged inside the first cylinder 91. After the second water pump 93 is turned on, the cleaning liquid inside the first cylinder 91 is input into the second cylinder 92 and finally sprayed out through the atomizing nozzle 96. Since the sieve plate 745 is arranged on one side of the atomizing nozzle 96, a avoidance hole 7451 which is offset from the atomizing nozzle 96 is provided on the sieve plate 745. When the avoidance hole 7451 is rotated to be connected with the outlet of the atomizing nozzle 96, the cleaning liquid will avoid the hole 7451 and spray on the ceramic ferrule. When the avoidance hole 7451 is rotated to be offset from the outlet of the atomizing nozzle 96, the cleaning liquid will not spray out. Therefore, intermittent liquid spraying occurs, which is convenient for cleaning the ceramic ferrule multiple times.

[0067] A baffle 7461 is installed at one end of the rotating plate 746, and the baffle 7461 is rotatably connected to the third cylinder 94. When the avoidance hole 7451 rotates to be misaligned with the outlet of the atomizing nozzle 96, the pressure sprayed by the atomizing nozzle 96 is too large, which will drive the third cylinder 94 and the second cylinder 92 to stretch the elastic member 97, so that the third cylinder 94 slides inside the baffle 7461 to avoid the flow of high-pressure liquid. At this time, the pressure of the liquid flowing out of the avoidance hole 7451 is relatively small and will not be sprayed on the ceramic ferrule, which facilitates the splashing of the gas on the ceramic ferrule.

[0068] The cleaned liquid flows out from the dust outlet hole 748 of the inner cylinder 744, and finally flows to the filter element 75 through the overflow hole 742 on one side of the connecting pipe 741 for filtration, and finally can be pumped into the first cylinder 91 by the first water pump 76 for reuse, which can save energy.

[0069] After cleaning, the ceramic ferrule is reinserted into the inspection port 62 of the optical fiber end face detector 61 by the mechanical arm 52 for re-inspection and confirmation. After the end face inspection is qualified, a clean dust cap is put on and the fiber is transferred to the next process.

[0070] Through the cooperation between the gas cleaning component 8 and the liquid cleaning component 9, the two can be controlled separately and can also be started at the same time, which can not only ensure the cleanliness of the end face of the ceramic ferrule, but also enable the end face to remain clean for a long time, thereby ensuring the end face yield and product quality.

[0071] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0072] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
