Description

Technical Field

[0001] This application belongs to the field of electronic component testing technology, and in particular relates to a switchable insulator leak detection test platform, leak detection system and method. Background Technology

[0002] In the electronics industry, with the continuous development of information technology, the application scope of electronic components, as the foundation of all electronic devices, has also expanded. Some components operate in extremely harsh environments, making their reliability a key concern. Sealing, as a crucial indicator of component reliability, has a significant impact on component lifespan. For example, poor sealing can lead to electromigration and ion contamination, causing anything from component failure to substantial economic losses.

[0003] In the overall structure of the encapsulation shell, the insulator is embedded between the metal sealing frame and the base. One end of it is connected to the external circuit through an external lead, and the other end is connected to the chip inside the shell. It plays the role of connecting the internal chip and the external circuit. It is a weak link in the sealing of the encapsulation shell, so it is particularly necessary to check the sealing of the ceramic insulator.

[0004] Helium mass spectrometry (HMS) leak detection has gained widespread application in the field of vacuum leak detection technology due to its high detection sensitivity and fast response speed. There are many HMS leak detection methods, but the most commonly used method for insulators is the helium spray method. One end of the insulator is connected to the instrument, a vacuum is created, and helium is sprayed from the other end of the insulator using a spray gun. If there is a leak in the device under test, when helium is sprayed onto the leak, the gas is immediately drawn into the vacuum system and diffuses into the mass spectrometry chamber. The gas is then analyzed and measured in the mass spectrometry chamber to determine whether the insulator's sealing performance is up to standard.

[0005] In existing insulator leak detection systems, only one insulator can be tested at a time, resulting in very low efficiency. However, hundreds, thousands, or even tens of thousands of insulators often need to be tested, requiring operators to waste a significant amount of time and energy. Furthermore, during the test, tweezers are needed to press and fix the insulator firmly to ensure a good seal between one end of the insulator and the vacuum side of the leak detection instrument. This operation is complex and lacks stability; even slight hand tremors or insufficient pressure can lead to test failure, necessitating retesting. This places high demands on the operators. Summary of the Invention

[0006] To overcome the problems existing in related technologies, this application provides a switchable insulator leak detection test platform, leak detection system and method to solve the problems of low leak detection efficiency, high time cost, complex operation and instability in existing leak detection systems.

[0055] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] To address the aforementioned issues, this application provides a switchable insulator leak detection test platform.

[0057] Reference Figure 1 The following is a detailed description of the switchable insulator leak detection test platform:

[0058] A switchable insulator leak detection test platform 100 includes: a clamping device 101, a gasket 102, a first cavity structure 103, a sealing gasket 104, a second cavity structure 105, and a pressure sensor 106.

[0059] The clamping device 101, gasket 102, first cavity structure 103, sealing gasket 104, and second cavity structure 105 are connected sequentially from top to bottom. The first cavity structure 103 and the second cavity structure 105 combine to form a cavity structure, and the gasket 102 is connected to the first cavity structure 103 through the first groove 1032. The pressure sensor 106 is located inside the clamping device 101, such as... Figure 1 As shown by the dashed line, the pressure sensor 106 is used to detect the pressure of the clamping device 101 when clamping the insulator.

[0060] For example, the first groove 1032 is located in the upper half of the first cavity structure 103. The sealing gasket 104 is used to seal the cavity structure.

[0061] Specifically, such as Figure 2 As shown, the clamping device 101 is provided with a plurality of first vent holes 1011; the first vent holes 1011 are connected to the high-pressure gas cylinder through multiple first channels, and a mass flow meter is provided on any one of the first channels; wherein, the mass flow meter is used to control the gas flow.

[0062] The number of first vent holes 1011 is the same as the number of first channels; the upper side of the first vent holes 1011 extends beyond the preset height of the plane of the pressing device 101 and is provided with threads for connection with the first channels. The pressing device 101 is provided with a second groove 1012 on its upper part for fixed connection with the drive frame 300; multiple pressure sensors 106 are placed inside the second groove 1012.

[0063] Specifically, the first vent 1011 includes a first channel and a second channel. The first channel is located above the second channel, which is located at the bottom of the vent. The second channel is shaped like a frustum of a cone, and the diameter of each cross-section of the frustum is larger than the diameter of the first channel, such as... Figure 3 and Figure 4 As shown, Figure 4 for Figure 3 A detailed view of the first vent in the section indicated by the dashed line.

[0064] Specifically, the gasket 102 is made of rubber; the gasket 102 is connected to the first cavity structure 103 by adsorption; the diameter of the gasket 102 is the same as the diameter of the pressing device 101. The gasket 102 is provided with a plurality of second vent holes 1021, the number of which is the same as the number of first vent holes 1011, such as... Figure 5 and Figure 6 As shown.

[0065] For example, the gasket 102 can be adsorbed onto the first cavity structure 103 by applying light fluorinated oil to the gasket 102.

[0066] For example, gasket 102 can also be a vacuum rubber material, which improves the sealing performance.

[0067] For example, the clamping device 101 has 13 first vent holes 1011, with 8 evenly distributed around the outermost ring, 4 evenly distributed around the middle ring, and 1 on the innermost ring. Figure 5The dotted lines in the diagram do not actually exist; they are marked in the figure to indicate the relationship between the three concentric circles containing the first vent hole 1011. These 13 vent holes are independent and do not affect each other. The upper side of each first vent hole, i.e., the upper side of the first channel, protrudes and is threaded, for connecting to the high-pressure gas cylinder via a vent pipe, i.e., the first channel. The lower side of each first vent hole, i.e., the second channel, is conically enlarged to facilitate smooth insertion of the insulator. The clamping device 101 has a slot, i.e., a second groove, on its upper part for easy fixing to the drive frame 300, allowing it to be controlled to move up and down using the drive frame 300. Furthermore, the slot contains four pressure sensors 106 to monitor the pressure of the clamping device 101 when clamping the insulator, ensuring a good seal on the lower side of the insulator before testing.

[0068] Specifically, the number of the first vent hole 1011 of the pressing device 101 and the number of the second vent hole 1021 of the gasket 102 are both n; the first vent hole 1011 and the second vent hole 1021 are distributed on three concentric circles of different diameters.

[0069] Among them, the positions of m first vent holes 1011 and m second vent holes 1021 correspond one-to-one and are located on the outermost concentric circle; the positions of p first vent holes 1011 and p second vent holes 1021 differ by a first preset angle and are located on the middle concentric circle; the positions of k first vent holes 1011 and k second vent holes 1021 differ by a second preset angle and are located on the innermost concentric circle; where m, p, and k add up to n.

[0070] The side of the gasket 102 also has a protrusion 1022, such as Figure 6 As shown, the edge of the first cavity structure 103 is provided with three grooves, such as... Figure 7 As shown, the grooves are, in order, the third groove 1033, the fourth groove 1034, and the fifth groove 1035; the protrusion 1022 mates with the grooves; when the protrusion 1022 is located in the third groove 1033, the m first vent holes 1011 and m second vent holes 1021 on the outermost concentric circle correspond one-to-one; when the gasket 102 is rotated by a first preset angle, the protrusion 1022 is located in the fourth groove 1034, and the p first vent holes 1011 and p second vent holes 1021 on the middle concentric circle correspond one-to-one; when the gasket 102 is rotated by a second preset angle, the protrusion 1022 is located in the fifth groove 1035, and the k first vent holes 1011 and k second vent holes 1021 on the innermost concentric circle correspond one-to-one.

[0071] For example, the gasket 102 is made of rubber and can be tightly adhered to the first cavity structure of the test platform 200. The gasket 102 has 13 second vent holes 1021. The outermost 8 second vent holes 1021 correspond one-to-one with the outermost 8 first vent holes 1011 of the clamping device 101. The middle ring of 4 second vent holes 1021 are rotated 30 degrees clockwise relative to the outermost 8 second vent holes 1021, and the innermost 1 second vent hole 1021 is rotated 60 degrees relative to the outermost 8 second vent holes 1021. The side of the gasket 102 has a protrusion 1022 for easy switching and fixing of the gasket 102. When the protrusion 1022 of the gasket 102 is in a groove of the first cavity structure 103, namely the third groove 1033, the outermost ring of 8 through holes corresponds one-to-one with the outermost 8 through holes of the pressing device 101; when the gasket 102 is rotated 30 degrees clockwise, the protrusion 1022 of the gasket 102 is in the second groove of the first cavity structure 103, namely the fourth groove 1034, the middle ring of through holes of the gasket 102 corresponds one-to-one with the middle ring of through holes of the pressing device 101; when the gasket 102 is rotated 30 degrees clockwise again, the protrusion 1022 of the gasket 102 is in the third groove of the first cavity structure 103, namely the fifth groove 1035, the innermost through hole of the gasket 102 corresponds to the innermost through hole of the pressing device 101.

[0072] Specifically, the first cavity structure 103 and the second cavity structure 105 are connected by multiple bolts 1037. The first cavity structure 103 is provided with multiple third vent holes 1031, which correspond one-to-one with the first vent holes 1011 of the pressing device 101, such as... Figure 7 , Figure 8 and Figure 9 As shown.

[0073] The first groove 1032 is provided on the upper surface of the first cavity structure 103 for positioning the gasket 102 and the clamping device 101. A column 1036 is provided in the middle of the first cavity structure 103, which passes through the gasket 102 and the clamping device 101, allowing the gasket 102 and the clamping device 101 to move vertically. Figure 8 and Figure 9 As shown.

[0074] Specifically, a fourth vent 1051 is provided on the lower side of the second cavity structure 105. The diameter of the fourth vent 1051 is the same as the diameter of the fifth vent of the leak detection device, and it is used to connect with the leak detection device.

[0075] For example, both the first cavity structure 103 and the second cavity structure 105 include four threaded holes, which correspond one-to-one. The first cavity structure 103 and the second cavity structure 105 are sealed and fixed together by bolts. The first cavity structure 103 and the second cavity structure 105 together form a cavity. To ensure the airtightness of both, a sealing gasket 104 is placed in a groove between the upper and lower halves. The first cavity structure 103 includes 13 third vent holes 1031, which correspond one-to-one with the first vent holes 1011 on the pressing device 101. The upper side of the first cavity structure 103 has a first groove 1032 with an inner diameter consistent with that of the gasket 102, facilitating the positioning of the gasket 102 and the pressing device 101. The gasket 102 and the pressing device 101 have the same diameter. A column 1036 is located in the middle of the first cavity structure 103, facilitating the vertical movement of the gasket 102 and the pressing device 101. The first cavity structure 103 has three grooves on its side, spaced 30 degrees apart, to facilitate the switching of channels for the gasket 102. The diameter of the vent hole on the lower half is the same as the diameter of the vent hole of the leak detection device, which facilitates connection with the leak detection device.

[0076] As can be seen, this invention utilizes a switchable insulator leak detection test platform. The beneficial effects of this invention compared to existing technologies are: a highly efficient, switchable insulator leak detection test platform with multiple test channels allows for simultaneous testing of multiple samples, significantly improving testing efficiency. The number of test channels is switchable simply by rotating the shim 102, making operation simple. If a test sample leaks, the sample can be screened by controlling the on / off state of the mass flow meter to determine which sample is leaking. The clamping device 101 is moved up and down by driving the platform 300 to clamp the test sample, improving upon the previous method of clamping with tweezers and enhancing stability and operability. The clamping device 101 contains a pressure sensor 106, which monitors the pressure value in real time during sample clamping. When the pressure reaches a certain value, the sealing of the lower side of the insulator is better, effectively ensuring the insulator's sealing before the test.

[0077] This application also provides a switchable insulator leak detection system, see [link to relevant documentation]. Figure 10 and Figure 11 The system includes: an experimental platform 100 for a switchable insulator leak detection system as described in the above embodiments, a high-pressure gas cylinder 200, a drive bench 300, a leak detection device 400, a data acquisition and display module 500, and a power supply module 600.

[0078] The high-pressure gas cylinder 200 is connected to the test platform 100 through multiple first channels, and a mass flow meter is installed on any one of the first channels; the test platform 100 is used to test multiple insulators; among them, the mass flow meter is used to control the gas flow.

[0079] The test platform 100 is fixedly connected to the drive frame 300; the drive frame 300 is used to control the up and down movement of the clamping device 101 in the test platform 100.

[0080] The leak detection device 400 is used to convert the detected gas into an electrical signal and send it to the data acquisition and display module 500.

[0081] The data acquisition and display module 500 is used to acquire electrical signals and display the leak detection results.

[0082] The power supply module 600 is used to provide voltage to the drive bench 300, the test platform 100, the leak detection device 400 and the data acquisition and display module 500.

[0083] Specifically, the first vent 1011 of the pressing device 101 is connected to the high-pressure gas cylinder through multiple first channels, and a mass flow meter is installed on any one of the first channels; wherein, the mass flow meter is used to control the gas flow.

[0084] For example, the high-pressure gas cylinder 200 is typically a high-pressure helium cylinder. The high-pressure helium cylinder can be equipped with a main valve, which is divided into three channels via a four-way adapter. Each channel contains three valves. Valve one is divided into eight channels, each connected to one of the eight outermost vent holes of the test platform 200 via threaded holes. Valve two is divided into four channels, each connected to one of the four middle vent holes of the test platform 200 via threaded holes. Valve three is one channel, connected to the innermost vent hole of the test platform 200. Additionally, each channel is equipped with a mass flow meter, which controls the flow of helium in each channel. If a defective product is detected in a certain channel during the test, the mass flow meter can be used to investigate the affected channel.

[0085] For example, the leak detection device 400, the data acquisition and display module 500, and the power supply module 600 can be integrated together in a single housing.

[0086] Specifically, the leak detection device 400 includes a vacuum pumping device, a mass spectrometer chamber, and a measurement circuit. It converts the detected helium gas into an electrical signal, which is then connected to the data acquisition and display module 500 to obtain the leak detection result.

[0087] The data acquisition and display module 500 is used to acquire the electrical signals of the leak detection device 400 and the signals of the pressure sensor 106 on the test platform 200, and display them in real time.

[0088] The power supply module 600 provides a stable voltage to the drive bench 300, test platform 200, leak detection device 400, and data acquisition and processing module to ensure the normal operation of each part.

[0089] This application also provides a switchable insulator leak detection method, applied to the aforementioned switchable insulator leak detection test platform.

[0090] The method includes: connecting a high-pressure gas cylinder 200 to a test platform 100 via multiple first channels, setting a mass flow meter on any one of the first channels, and using the test platform 100 to test the insulator; wherein the mass flow meter is used to control the flow of gas.

[0091] The test platform 100 is fixedly connected to the drive frame 300, and the drive frame 300 is used to control the clamping device 101 in the test platform 100 to move up and down.

[0092] The leak detection device 400 converts the detected gas into an electrical signal and sends it to the data acquisition and display module 500.

[0093] The data acquisition and display module 500 acquires electrical signals and displays the leak detection results.

[0094] The power supply module 600 provides voltage to the drive bench 300, the test platform 100, the leak detection device 400, and the data acquisition and display module 500.
