Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a multi-channel helium detection device for 5G communication components. Background Technology

[0002] 5G communication uses high-frequency bands (such as millimeter waves), making it sensitive to signal attenuation. The sealing of components directly affects transmission stability. Taking RF coaxial connectors as an example, their leakage rate must be controlled below extremely low standards; otherwise, it will lead to signal failure or equipment malfunction. 5G base stations need to cope with extreme environments such as high temperature, high humidity, and salt spray. Component sealing failure will accelerate material corrosion and shorten equipment lifespan. Helium leak detection can detect micron-level gaps, ensuring long-term stable operation of components under harsh conditions. Helium leak detection is widely used as a standard for airtightness testing in fields such as 5G optoelectronic devices and semiconductor equipment, with detection accuracy far exceeding that of traditional pressure testing. Helium leak detection utilizes the small size and fast diffusion speed of helium molecules, using mass spectrometry to detect leaks. During testing, the component is placed in a high-pressure helium environment, allowing helium to seep into potential gaps. The component is then placed in a vacuum chamber, allowing helium to escape from the gaps. Finally, a helium mass spectrometer is used to capture the escaped helium, and the leakage rate is quantified by the ion current intensity.

[0003] However, existing helium testing equipment can usually only test individual components of the same model in the same chamber, resulting in low testing efficiency, inconvenience for continuous helium recovery, and high cost. Utility Model Content

[0024] 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.

[0025] Please see Figure 1-6 and Figure 8The 5G communication component multi-channel helium detection equipment of this embodiment includes a first frame 1 and a second frame 2 and a third frame 3 disposed on both sides of the first frame 1. A first translation mechanism 6 is horizontally arranged in the middle of the second frame 2. The moving platform of the first translation mechanism 6 is detachably provided with a first feeding plate 7. A first mounting frame 4 is provided on the upper side of the end of the first translation mechanism 6 facing the first frame 1. A first sealing box 5 is fixedly connected to the top of the first mounting frame 4. A second translation mechanism 13 is horizontally arranged in the middle of the third frame 3. A second feeding plate 14 is detachably provided on the moving platform of the second translation mechanism 13. A second mounting frame 11 is provided on the upper side of the end of the second translation mechanism 13 facing the first frame 1. The top of the second mounting frame 11 is fixedly connected to the first frame 1. The first and second sealing boxes 12 are fixedly connected. The top edges of the first and second feeding plates 7 and 14 are provided with several air inlet joints 21. The interiors of the first and second sealing boxes 5 and 12 are provided with several chambers. The first translation mechanism 6 is provided with a first limiting block 8 at the middle of the end away from the first frame 1. The first lifting mechanism 10 is vertically provided on the lower side of the end of the first translation mechanism 6 facing the first frame 1. The first lifting mechanism 10 is located directly below the first sealing box 5. The second translation mechanism 13 is provided with a second limiting block 15 at the middle of the end away from the first frame 1. The second lifting mechanism 17 is vertically provided on the lower side of the end of the second translation mechanism 13 facing the first frame 1. The second lifting mechanism 17 is located directly below the second sealing box 12. Before testing, the components to be tested are placed on top of the first loading plate 7 and the second loading plate 14 according to their size and the position of the chambers. Then, several air inlet connectors 21 on the top of the first loading plate 7 and the second loading plate 14 are connected to the air holes on the surface of the components through flexible hoses. Then, the first translation mechanism 6 and the second translation mechanism 13 drive the first loading plate 7 and the second loading plate 14 to the bottom of the first sealing box 5 and the second sealing box 12, respectively. At this time, the first lifting mechanism 10 and the second lifting mechanism 17 drive the first loading plate 7 and the second loading plate 14 to move upward until the first loading plate 7 abuts against the bottom of the first sealing box 5, and the second loading plate 14 abuts against the bottom of the second sealing box 12. This allows the components to be located in different chambers inside the first sealing box 5 and the second sealing box 12, facilitating subsequent testing. Through the above steps, continuous and synchronous testing of various types and sizes of components in different chambers can be achieved, effectively improving the testing efficiency of the equipment.

[0026] The first sealed box 5 has a first connecting hole 9 on one side wall facing the first frame 1, and the second sealed box 12 has a second connecting hole 16 on one side wall facing the first frame 1. A pair of vacuum pumps 18 are fixedly connected to the upper side of the first frame 1. A first connecting pipe 19 connects the vacuum pumps 18 to the first connecting hole 9, and a second connecting pipe 20 connects the vacuum pumps 18 to the second connecting hole 16. After the first sealed box 5 and the second sealed box 12 are sealed, the vacuum pumps 18 evacuate several chambers inside the first sealed box 5 and the second sealed box 12 through the first connecting pipe 19 and the second connecting pipe 20, respectively, so that the components are in a vacuum environment and the air inside them is discharged.

[0027] A gas pump 22 is fixedly connected to the bottom of the first frame 1. The gas pump 22 is connected to several gas inlet connectors 21, and a solenoid valve 23 is installed between each gas inlet connector 21 and the gas pump 22. During testing, helium gas is sequentially injected into the corresponding chamber components through the gas pump 22 along the gas inlet connectors 21, causing the helium gas to flow out along the gaps on the outer wall of the component. Finally, the escaped helium gas is captured by a helium mass spectrometer leak detector, and the leak rate is quantified by the ion current intensity, realizing continuous detection of components in different chambers. During testing, the flow rate and pressure of helium gas injected into different chambers can be precisely controlled and adjusted by the solenoid valves 23, which facilitates continuous recovery of helium gas while testing multiple components.

[0028] Working principle: Before testing, the components to be tested are placed on top of the first loading plate 7 and the second loading plate 14 according to their size and the position of the chamber. Then, several air inlet connectors 21 on the top of the first loading plate 7 and the second loading plate 14 are connected to the air holes on the surface of the components through flexible hoses. Then, the first translation mechanism 6 and the second translation mechanism 13 drive the first loading plate 7 and the second loading plate 14 to the bottom of the first sealing box 5 and the second sealing box 12, respectively. At this time, the first lifting mechanism 10 and the second lifting mechanism 17 drive the first loading plate 7 and the second loading plate 14 to move upward until the first loading plate 7 abuts against the bottom of the first sealing box 5, and the second loading plate 14 abuts against the bottom of the second sealing box 12. This allows the components to be located in different chambers inside the first sealing box 5 and the second sealing box 12, facilitating subsequent testing. Through the above steps, continuous and synchronous testing of various types and sizes of components in different chambers can be achieved, effectively improving the testing efficiency of the equipment.

[0029] During testing, after the first sealed box 5 and the second sealed box 12 are sealed, the vacuum pump 18 evacuates several chambers inside the first sealed box 5 and the second sealed box 12 through the first connecting pipe 19 and the second connecting pipe 20, respectively, so that the components are in a vacuum environment and the air inside them is discharged. Then, the gas filling pump 22 fills the corresponding chambers of the components with helium through the gas inlet connector 21, so that the helium flows out through the gaps on the outer wall of the components. Finally, the escaped helium is captured by the helium mass spectrometer leak detector, and the leak rate is quantified by the ion current intensity, so as to realize the continuous detection of components in different chambers. During testing, the flow rate and pressure of the helium filling in different chambers can be precisely controlled and adjusted by the solenoid valve 23, which facilitates the continuous recovery of helium while testing multiple components.
