Description

Technical Field

[0001] The present invention relates to the technical field of airtightness detection, and specifically to an airtightness detection device for an optical communication lens cap. Background Art

[0002] An optical communication lens cap is usually a component used in an optical communication system, especially in optical fiber communication. It is mainly used to protect and fix optical fibers or optical lenses to ensure their stability and safety.

[0003] During the production of an optical communication lens cap, it is necessary to perform airtightness detection on the sealed part between the lens and the cap. This detection is to ensure that gas or moisture does not penetrate and affect the performance of the lens. Currently, most of the detection methods rely on manual operation, but manual operation has problems such as low detection efficiency, quality fluctuations in manual operation, and human errors. Although there are now special detection devices for detection, during the detection process, due to the inability to ensure the airtightness between the optical communication lens cap and the ventilation device, when gas is filled into the optical communication lens cap, some gas will leak out from the connection between the two, which will lead to inaccurate detection data for the optical communication lens cap.

[0018] The present invention provides an airtightness detection device for an optical communication lens cap. Compared with the prior art, it has the following beneficial effects:

[0019] 1. In the present invention, the optical communication lens cap is conveyed by the conveyor belt. The driving motor drives the driving disc to rotate reciprocally. When the driving disc rotates, it drives the driving plate to rotate. The driving groove on the driving plate cooperates with the driving column, so that the connecting plate is limited by the positioning slider and the positioning slide rod, thereby realizing a "∏" movement. When the inlet of the detection cylinder fits with the upper end face of the optical communication lens cap, the lens on the optical communication lens cap is inside the detection cylinder. Then, the electric push rod fixes the optical communication lens cap on the detection cylinder, and then uses the "∏" movement to conveniently move the optical communication lens cap on the conveyor belt to the detection frame. By starting the air pump, gas enters the inside of the optical communication lens cap through the ventilation pipe. The pressure sensor in the detection cylinder is used to detect the air pressure change inside the lens cap. By real-time monitoring of the pressure data, it is judged whether the lens cap has good airtightness. The whole process is completed by automatic control of the conveyor belt, and the sequential detection from one optical communication lens cap to the next optical communication lens cap ensures that each optical communication lens cap can be effectively detected for airtightness, effectively improving the production efficiency and the reliability of quality control;

[0020] 2. In the present invention, when the positioning slider slides on the positioning slide bar, it will drive the piston on the connecting push rod to move in the exhaust cylinder. The gas in the exhaust cylinder will enter the exhaust pipe, and part of the gas in the exhaust pipe will enter the push pipe. The gas in the push pipe will drive the push rod on the push plate to push the U-shaped push rod, and the U-shaped push rod is used to drive the cleaning roller on the sliding block to clean the surface of the detection frame, ensuring that the bottom end of the optical communication lens cap fits the end face of the detection frame, and ensuring that when the optical communication lens cap is detected, the detection result will not be interfered by impurities.

[0021] 3. In the present invention, when the cleaning roller slides horizontally, the cleaning roller will ensure that it rotates during the horizontal movement using the sliding block through the cooperation of the auxiliary gear on the connecting rotating shaft and the auxiliary toothed plate, as well as the cooperation between the connecting rotating shaft and the bearing. The rotation of the cleaning roller is used to improve the cleaning effect.

[0022] 4. In the present invention, when the connecting plate drives the optical communication lens cap to descend, the sealing ring will be driven by the U-shaped push rod to be at the exact center position of the detection frame. During the continuous descent of the optical communication lens cap, the sealing ring will be on the outside of the optical communication lens cap. At the same time, the sealing airbag in the sealing ring will expand due to the filling of another part of the gas in the exhaust pipe. Through the expansion of the sealing airbag and the synergistic effect of the sealing ring, a stable sealing environment is formed at the contact surface between the optical communication lens cap and the detection frame, effectively enhancing the airtightness detection effect of the optical communication lens cap and avoiding air leakage or errors.

Since the stepping motor and the conveyor roller are well-known technologies to those skilled in the art, no specific description will be made here;

[0034] The intermittent gripping assembly includes a driving motor 11 fixedly installed on the mounting frame plate 7.

One end of the driving column 21 far away from the connecting plate 20 passes through the driving groove 14 and extends into the U-shaped groove 16. The driving column 21 is in sliding contact with the driving groove 14 and the U-shaped groove 16. The position of the optical communication lens cap is fixed by the two clamping plates 24, so that the lens end surface of the optical communication lens cap fits with the inlet of the detection cylinder 9.

[0035] In this embodiment, the optical communication lens cap is conveyed by the conveyor belt 2. The driving motor 11 is used to drive the driving disk 12 to rotate reciprocally. When the driving disk 12 rotates, it will drive the driving plate 13 to rotate. By using the cooperation between the driving groove 14 on the driving plate 13 and the driving column 21, the connecting plate 20 is limited by the positioning slider 18 and the positioning slide bar 17, so as to realize a "∏"-shaped movement. When the inlet of the detection cylinder 9 fits with the upper end surface of the optical communication lens cap, the lens on the optical communication lens cap is inside the detection cylinder 9. Then, the electric push rod 23 fixes the optical communication lens cap on the detection cylinder 9. Then, the "∏"-shaped movement is used to move the optical communication lens cap on the conveyor belt 2 to the detection rack 3. By starting the air pump 4, the gas enters the inside of the optical communication lens cap through the ventilation pipe 5. The pressure sensor 10 in the detection cylinder 9 is used to detect the air pressure change inside the lens cap. By real-time monitoring of the pressure data, it is judged whether the lens cap has good airtightness. The whole process is completed by the automatic control of the conveyor belt 2. The sequential detection from one optical communication lens cap to the next optical communication lens cap ensures that each optical communication lens cap can be effectively subjected to airtightness detection, effectively improving the production efficiency and the reliability of quality control.

[0036] An auxiliary component is provided on the mounting base plate 1 and on one side of the detection frame 3. Through the auxiliary component, the detection frame 3 is closely attached to the optical communication lens cap to ensure the accuracy of the airtightness detection. The auxiliary component includes a stabilizing plate 25 fixedly installed on the mounting frame plate 7. A exhaust cylinder 26 is fixedly installed on the stabilizing plate 25. A connecting push rod 27 is slidably installed on the exhaust cylinder 26. The air outlet of the exhaust cylinder 26 is fixedly communicated with an exhaust pipe 28. A mounting vertical plate 29 is fixedly installed on the mounting base plate 1. A push tube 30 is fixedly installed on the mounting vertical plate 29. A spring 31 is fixedly connected inside the push tube 30. One end of the spring 31 away from the push tube 30 is fixedly connected with a push plate 32. A push rod 33 is fixedly installed on the push plate 32. Symmetrically arranged U-shaped plates 34 are fixedly installed on the mounting base plate 1. A sliding groove 35 is opened on the U-shaped plate 34. A sliding block 36 is slidably installed inside the sliding groove 35. A bearing 37 is fixedly installed on the sliding block 36. A connecting rotating shaft 38 is fixedly installed on the bearing 37. A cleaning roller 39 is fixedly installed at one end of the connecting rotating shaft 38. A U-shaped push rod 40 is fixedly installed at one end of the sliding block 36. An auxiliary gear 41 is fixedly installed at the other end of the connecting rotating shaft 38. An auxiliary tooth plate 42 is fixedly installed on the outer side of the U-shaped plate 34. An air inlet pipe is provided on the exhaust cylinder 26, and check valves are provided on both the air inlet pipe and the exhaust pipe 28. The other end of the push rod 33 is fixedly connected with a piston. At the same time, the principle of the exhaust cylinder 26 is the same as that of a bicycle pump in the prior art. The air inlet pipe, the check valve, the piston and the bicycle pump are all well-known technologies to those skilled in the art and will not be specifically described here;

[0037] One end of the connecting push rod 27 away from the exhaust cylinder 26 is fixedly connected with the positioning slider 18. One end of the exhaust pipe 28 away from the exhaust cylinder 26 is fixedly communicated with the push tube 30. The end of the push rod 33 away from the push plate 32 extends to the outside of the push tube 30 and is fixedly connected with the U-shaped push rod 40. The U-shaped push rod 40 is slidably connected with the U-shaped plate 34. The cleaning roller 39 is located inside the two U-shaped plates 34. The end face of the detection frame 3 is cleaned by the cleaning roller 39. The auxiliary gear 41 meshes with the auxiliary tooth plate 42. The spring 31 is located outside the push rod 33. The spring 31 is used to ensure that the push plate 32 can return to its original position.

[0038] In this embodiment, when the positioning slider 18 slides on the positioning slide bar 17, it will drive the piston on the connecting push rod 27 to move in the exhaust cylinder 26. The gas in the exhaust cylinder 26 will enter the exhaust pipe 28. Part of the gas in the exhaust pipe 28 will enter the push pipe 30. The gas in the push pipe 30 will drive the push rod 33 on the push plate 32 to push the U-shaped push rod 40. The U-shaped push rod 40 is used to drive the cleaning roller 39 on the sliding block 36 to clean the surface of the detection frame 3, ensuring that the bottom end of the optical communication lens cap fits the end face of the detection frame 3, and ensuring that when the optical communication lens cap is detected, it will not be interfered by impurities and affect the detection result. When the cleaning roller 39 slides horizontally, the cleaning roller 39 will cooperate with the auxiliary gear 41 on the connecting rotating shaft 38 and the auxiliary toothed plate 42, and the cooperation between the connecting rotating shaft 38 and the bearing 37, ensuring that the cleaning roller 39 rotates while moving horizontally by using the sliding block 36, and improving the cleaning effect by the rotation of the cleaning roller 39.

[0039] An inner connecting rod 43 is fixedly installed on the inner side of the U-shaped push rod 40. A sealing ring 44 is fixedly installed on the connecting rod 43. An annular groove 45 is formed on the inner side surface of the sealing ring 44. A sealing airbag 46 is fixedly installed inside the annular groove 45. A connecting pipe 47 is fixedly communicated with the sealing airbag 46. One end of the connecting pipe 47 away from the sealing airbag 46 is fixedly communicated with a telescopic hose 48. One end of the telescopic hose 48 away from the connecting pipe 47 is fixedly communicated with an L-shaped pipe 49. One end of the connecting pipe 47 away from the sealing airbag 46 extends to the outside of the sealing ring 44. One end of the L-shaped pipe 49 away from the telescopic hose 48 is fixedly communicated with the exhaust pipe 28. A valve is arranged on the L-shaped pipe 49 to determine whether the L-shaped pipe 49 is ventilated. Since the valve is a well-known technology for those skilled in the art, it will not be specifically described here.

[0040] In this embodiment, when the connecting plate 20 drives the optical communication lens cap to descend, the sealing ring 44 will be driven by the U-shaped push rod 40 to be in the center position of the detection frame 3. During the continuous descent of the optical communication lens cap, the sealing ring 44 will be on the outside of the optical communication lens cap. At the same time, the sealing airbag 46 in the sealing ring 44 will expand by the filling of another part of the gas in the exhaust pipe 28. Through the expansion of the sealing airbag 46 and the cooperation of the sealing ring 44, a stable sealing environment is formed at the contact surface between the optical communication lens cap and the detection frame 3, effectively enhancing the airtightness detection effect of the optical communication lens cap and avoiding air leakage or errors.

[0041] Working principle:

[0042] During use, place the optical communication lens cap to be subjected to airtightness detection on the conveyor belt 2, and ensure that there is a certain distance between the optical communication lens caps;

[0043] The optical communication lens cap is conveyed by the conveyor belt 2. By using the driving motor 11 to drive the driving disk 12 to rotate reciprocally, when the driving disk 12 rotates, it will drive the driving plate 13 to rotate. By using the driving groove 14 on the driving plate 13 to cooperate with the driving column 21, the connecting plate 20 is limited by the positioning slider 18 and the positioning slide bar 17, so as to realize the "∏" motion. When the entrance of the detection cylinder 9 fits with the upper end surface of the optical communication lens cap, the lens on the optical communication lens cap is inside the detection cylinder 9. Then the electric push rod 23 fixes the optical communication lens cap on the detection cylinder 9. By using the "∏" motion, it is convenient to move the optical communication lens cap on the conveyor belt 2 to the detection rack 3. By starting the air pump 4, the gas enters the inside of the optical communication lens cap through the ventilation pipe 5. The pressure sensor 10 in the detection cylinder 9 is used to detect the air pressure change inside the lens cap. By real-time monitoring of the pressure data, it is judged whether the lens cap has good airtightness. The whole process is completed by the automatic control of the conveyor belt 2. The sequential detection from one optical communication lens cap to the next optical communication lens cap ensures that each optical communication lens cap can be effectively detected for airtightness;

[0044] When the positioning slider 18 slides on the positioning slide bar 17, it will drive the piston on the connecting push rod 27 to move in the exhaust cylinder 26. The gas in the exhaust cylinder 26 will enter the exhaust pipe 28. Part of the gas in the exhaust pipe 28 will enter the push pipe 30. The gas in the push pipe 30 will drive the push rod 33 on the push plate 32 to push the U-shaped push rod 40. By using the U-shaped push rod 40 to drive the cleaning roller 39 on the sliding block 36 to clean the surface of the detection rack 3, it is ensured that the bottom end of the optical communication lens cap fits with the end surface of the detection rack 3, and it is ensured that when the optical communication lens cap is detected, it will not be interfered by impurities and affect the detection result;

[0045] When the cleaning roller 39 is sliding horizontally, the cleaning roller 39 will cooperate with the auxiliary gear 41 on the connecting rotating shaft 38 and the auxiliary toothed plate 42, and cooperate with the connecting rotating shaft 38 and the bearing 37, so as to ensure that when the cleaning roller 39 moves horizontally by using the sliding block 36, it is in a rotating state. By using the rotation of the cleaning roller 39, the cleaning effect can be improved;

[0046] When the connecting plate 20 drives the optical communication lens cap to descend, the sealing ring 44 will be driven by the U-shaped push rod 40 to be at the exact center position of the detection frame 3. During the continuous descent of the optical communication lens cap, the sealing ring 44 will be on the outside of the optical communication lens cap. At the same time, the sealing airbag 46 inside the sealing ring 44 will expand due to the filling of another part of the gas in the exhaust pipe 28. Through the expansion of the sealing airbag 46 and the synergistic effect of the sealing ring 44, a stable sealing environment is formed at the contact surface between the optical communication lens cap and the detection frame 3, effectively enhancing the airtightness detection effect of the optical communication lens cap and avoiding air leakage or errors.

[0047] In this technical solution, when the cleaning roller 39 cleans the surface of the detection frame 3, the optical communication lens cap is in the horizontal movement during the "∏" movement. At this time, the L-shaped pipe 49 will be in a non-ventilated state through the action of the valve. When the optical communication lens cap is in the vertical downward movement during the "∏" movement and the optical communication lens cap is inside the sealing ring 44, the valve on the L-shaped pipe 49 is opened at this time, so that another part of the gas in the exhaust pipe 28 enters the sealing airbag 46, and the sealing airbag 46 is used to ensure the sealing between the optical communication lens cap and the sealing ring 44. At the same time, in order to ensure that the environment inside the detection cylinder 9 is in a low-pressure environment and ensure that the pressure sensor 10 can accurately detect whether the optical communication lens cap leaks air, a pump body can be set on the detection cylinder 9, and the gas inside the detection cylinder is pumped away through the pump body to ensure that the inside of the detection cylinder 9 is in a stable environment. Since the principle of the pump body is a well-known technology to those skilled in the art, it will not be specifically described here.

[0048] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0049] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
