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

[0003] During the production process of optical communication lens caps, it is necessary to perform an airtightness test on the sealing part between the lens and the cap.

[0015] The present invention provides an airtightness detection device for an optical communication lens cap. Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention conveys the optical communication lens tube cap through a conveyor belt, and drives the driving disk to reciprocate by using a driving motor. When the driving disk rotates, it drives the driving plate to rotate. The driving groove on the driving plate cooperates with the driving column to make the connecting plate pass through the limit of the positioning slider and the positioning slide rod, thereby realizing the "∏" movement. When the entrance of the detection tube is in contact with the end face of the optical communication lens tube cap, the lens on the optical communication lens tube cap is inside the detection tube, and then the electric push rod fixes the optical communication lens tube cap on the detection tube, and then the "∏" movement is used to facilitate the optical communication lens tube cap on the conveyor belt. The communication lens cap is moved to the detection rack, and the air pump is started to allow the gas to enter the interior of the optical communication lens cap through the ventilation pipe. The pressure sensor in the detection tube is used to detect the air pressure change inside the lens cap. By real-time monitoring of the pressure data, it is determined whether the lens cap has good air tightness. 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 tested for air tightness, effectively improving production efficiency and the reliability of quality control; 2. In the present invention, when the positioning slider slides on the positioning slide rod, it drives the piston connected to the push rod to move in the exhaust pipe, and the gas in the exhaust pipe enters the exhaust pipe. Part of the gas in the exhaust pipe enters the push pipe, and the gas in the push pipe drives the push rod on the push plate to push the U-shaped push rod. 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 with the end face of the detection frame, ensuring that the optical communication lens cap will not interfere with the detection result due to impurities during detection; 3. In the present invention, when the cleaning roller is in the process of horizontal sliding, the cleaning roller will ensure that the cleaning roller is in a rotating state during the process of horizontal movement by the sliding block through the cooperation between the auxiliary gear and the auxiliary tooth plate on the connecting shaft, and the cooperation between the connecting shaft and the bearing, so as to improve the cleaning effect by the rotation of the cleaning roller; 4. In the present invention, when the optical communication lens cap is in the process of being driven by the connecting plate to descend, the sealing ring will be located at the exact center of the detection frame through the driving of the U-shaped push rod. During the continuous descent of the optical communication lens cap, the sealing ring will be located 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 synergistic effect of the expansion of the sealing airbag and the sealing ring, a stable sealing environment is formed at the contact surface of the optical communication lens cap and the detection frame, thereby effectively enhancing the airtightness detection effect of the optical communication lens cap and avoiding the occurrence of air leakage or errors.

One end of the push rod 33 away from the push plate 32 extends to the outside of the push pipe 30 and is fixedly connected to the U-shaped push rod 40. The U-shaped push rod 40 is slidingly connected to the U-shaped plate 34. The cleaning roller 39 is located on the inner side of the two U-shaped plates 34. The end surface of the detection frame 3 is cleaned by the cleaning roller 39. The auxiliary gear 41 is meshed with the auxiliary tooth plate 42. The spring 31 is located on the outside of the push rod 33. The spring 31 is used to ensure that the push plate 32 can return to its original position.

[0022] In this embodiment, when the positioning slider 18 slides on the positioning slider 17, it will drive the piston on the connecting push rod 27 to move in the exhaust pipe 26, and the gas in the exhaust pipe 26 will enter the exhaust pipe 28. Part of the gas in the exhaust pipe 28 will enter the push tube 30. The gas in the push tube 30 will drive the push rod 33 on the push plate 32 to push the U-shaped push rod 40.

When the cleaning roller 39 is in the process of horizontal sliding, the cleaning roller 39 will ensure that the cleaning roller 39 is in a rotating state during the horizontal movement of the sliding block 36 through the cooperation between the auxiliary gear 41 and the auxiliary tooth plate 42 on the connecting shaft 38, and the cooperation between the connecting shaft 38 and the bearing 37, and the rotation of the cleaning roller 39 is used to improve the cleaning effect.

[0023] A connecting rod 43 is fixedly installed on the inner side of the U-shaped push rod 40, and a sealing ring 44 is fixedly installed on the connecting rod 43. An annular groove 45 is provided on the inner side of the sealing ring 44, and a sealing airbag 46 is fixedly installed inside the annular groove 45.

A valve is provided on the L-shaped pipe 49, and the valve is used to determine whether the L-shaped pipe 49 is ventilated. Since valves are a technology well known to people in this field, they are not described in detail here.

[0024] In the present embodiment, when the optical communication lens cap is in the process of being driven by the connecting plate 20 to be in the process of being lowered, the sealing ring 44 will be located at the exact center of the detection frame 3 through the driving of the U-shaped push rod 40. During the continuous lowering of the optical communication lens cap, the sealing ring 44 will be located at the outside of the optical communication lens cap. At the same time, the sealing airbag 46 in the sealing ring 44 will be expanded by the filling of another part of the gas in the exhaust pipe 28. Through the synergistic effect of the expansion of the sealing airbag 46 and the sealing ring 44, the contact surface between the optical communication lens cap and the detection frame 3 forms a stable sealing ring 44 environment, which effectively enhances the airtightness detection effect of the optical communication lens cap and avoids the occurrence of air leakage or errors.

[0025] Working principle: When in use, the optical communication lens caps that need to be tested for air tightness are placed on the conveyor belt 2, and a certain distance is ensured between the optical communication lens caps; The optical communication lens cap is conveyed by the conveyor belt 2, and the driving motor 11 drives the driving disk 12 to reciprocate. When the driving disk 12 rotates, it drives the driving plate 13 to rotate. The driving groove 14 on the driving plate 13 cooperates with the driving column 21 to make the connecting plate 20 pass through the positioning slider 18 and the positioning slide bar 17 to achieve the "∏" movement. When the entrance of the detection tube 9 is in contact with the end face of the optical communication lens cap, the lens on the optical communication lens cap is inside the detection tube 9, and then the electric push rod 23 fixes the optical communication lens cap on the detection tube 9, and then The "∏" motion is used to facilitate the movement of the optical communication lens tube cap on the conveyor belt 2 to the detection rack 3. By starting the air pump 4, the gas enters the interior of the optical communication lens tube cap through the ventilation pipe 5. The pressure sensor 10 in the detection tube 9 is used to detect the air pressure change inside the lens tube cap. By real-time monitoring of the pressure data, it is determined whether the lens tube cap has good air tightness. The whole process is completed by the automatic control of the conveyor belt 2. The sequential detection from one optical communication lens tube cap to the next optical communication lens tube cap ensures that each optical communication lens tube cap can be effectively tested for air tightness. When the positioning slide block 18 slides on the positioning slide bar 17, it will drive the piston on the connecting push rod 27 to move in the exhaust tube 26, and the gas in the exhaust tube 26 will enter the exhaust pipe 28. Part of the gas in the exhaust pipe 28 will enter the push tube 30. The gas in the push tube 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 with the end face of the detection frame 3, ensuring that the optical communication lens cap will not interfere with the detection result due to impurities during detection; When the cleaning roller 39 is in the process of horizontal sliding, the cleaning roller 39 will ensure that the cleaning roller 39 is in a rotating state during the horizontal movement of the sliding block 36 through the cooperation between the auxiliary gear 41 and the auxiliary tooth plate 42 on the connecting shaft 38, and the cooperation between the connecting shaft 38 and the bearing 37, so as to improve the cleaning effect by the rotation of the cleaning roller 39; When the optical communication lens cap is in the process of being lowered by the connecting plate 20, the sealing ring 44 will be located at the exact center of the detection frame 3 through the driving of the U-shaped push rod 40. During the continuous lowering of the optical communication lens cap, the sealing ring 44 will be located on the outside of the optical communication lens cap. At the same time, the sealing airbag 46 in the sealing ring 44 will expand due to the filling of another part of the gas in the exhaust pipe 28. Through the synergistic effect of the expansion of the sealing airbag 46 and the sealing ring 44, a stable sealing ring 44 environment is formed on the contact surface between the optical communication lens cap and the detection frame 3, thereby effectively enhancing the airtightness detection effect of the optical communication lens cap and avoiding the occurrence of air leakage or errors.

[0026] In the present technical solution, when the cleaning roller 39 cleans the surface of the detection frame 3, the optical communication lens cap is in a horizontal movement in the "∏" motion. At this time, the L-shaped tube 49 will be in a non-ventilated state through the action of the valve. When the optical communication lens cap is in the process of vertically downward movement in the "∏" motion, and the optical communication lens cap is inside the sealing ring 44, the valve on the L-shaped tube 49 is opened, so that another part of the gas in the exhaust pipe 28 enters the sealing airbag 46. 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 tube 9 is in a low-pressure environment and to ensure that the pressure sensor 10 can accurately detect whether the optical communication lens cap is leaking, a pump body can be set on the detection tube 9, and the gas in the detection tube is pumped away by the pump body to ensure that the inside of the detection tube 9 is in a stable environment. Since the principle of the pump body is a technology well known to people in this field, it will not be described in detail here.
