Description

Technical Field

[0001] The present application relates to the field of atmosphere detection technology, and in particular to a device, method, equipment, storage medium and program product for sampling the internal atmosphere of a device. Background Art

[0002] With the rapid development of electronic devices, their application scenarios are becoming increasingly extensive. In order to adapt to the actual needs of various environments and scenarios, hermetically sealed components have come into being. Hermetically sealed components are widely used due to their excellent environmental adaptability and reliability. The internal cavity of hermetically sealed components is generally filled with high-purity nitrogen or other inert gases. However, during the packaging or application process, water vapor, oxygen, carbon dioxide, or organic gases may be introduced, causing the internal chip to accelerate degradation or even failure, affecting the reliability of the component. Therefore, it is usually necessary to strictly control and accurately detect the composition and content of the atmosphere inside the hermetically sealed component to ensure the application reliability of the component.

[0003] In traditional technology, the packaging structure of the component sample is usually directly destroyed, and then the escaping atmosphere is collected for component detection and analysis.

[0047] In an exemplary embodiment, Figure 1 As shown, a device for sampling the internal atmosphere of a device is provided, which includes a sampling chamber 102 and a puncture module 104. A puncture hole 1021 is opened on the cavity body of the sampling chamber, and the puncture module 104 is arranged in the sampling chamber 102 and corresponding to the puncture hole 1021.

[0048] It should be noted that the internal cavity of hermetic sealed components is generally filled with high-purity nitrogen or other inert gases. However, during the packaging or application process, water vapor, oxygen, carbon dioxide or organic gases may be introduced, causing the internal chip to accelerate degradation or even failure, affecting the reliability of the component. Therefore, it is usually necessary to strictly control and accurately detect the atmosphere composition and content inside the hermetic sealed components to ensure the application reliability of the components. Before performing atmosphere testing, it is necessary to sample the atmosphere inside the hermetic sealed component. Then, the sampled atmosphere can be transmitted to a mass spectrometer, gas chromatograph or other detection instrument for component detection. The device internal atmosphere sampling device provided in this embodiment is used to sample the atmosphere to be tested inside the device to be tested 202, wherein the device to be tested 202 refers to the airtight packaged component to be sampled, and the atmosphere to be tested refers to the atmosphere inside the device to be tested. The atmosphere to be tested is filled in the air-filled cavity 2021 of the device to be tested 202. When sampling from the air-filled cavity 2021, at least the cavity wall of the air-filled cavity 2021 needs to be pierced to allow the atmosphere to be tested in the air-filled cavity 2021 to escape.

[0049] The sampling chamber 102 is a cavity structure having an internal space capable of accommodating gas. A puncture hole 1021 is provided on the cavity of the sampling chamber 102. The puncture hole 1021 is used to form a gas channel between the gas-filled cavity 2021 of the device under test 202 and the sampling chamber 102. When collecting the atmosphere to be measured, the sampling chamber 102 is in a sealed state and is connected to the gas-filled cavity 2021 of the device under test 202 only through the puncture hole 1021, so that the atmosphere to be measured in the gas-filled cavity 2021 can escape into the sampling chamber 102 through the puncture hole 1021. A puncture module 104 is provided in the sampling chamber 102. For example, the puncture module 104 can be a puncture needle. The puncture needle has a small force-bearing area and a fast puncture speed, resulting in a small deformation of the shell surface and a small puncture depth, which is conducive to improving puncture efficiency and sampling quality. The puncture module 104 can move under the action of external force. The puncture module 104 is correspondingly arranged to the puncture hole 1021 so that the needle tip of the puncture module 104 can pass through the puncture hole 1021 and pierce the outside of the sampling cavity 102 during the movement of the puncture module 104. In this way, before sampling, the shell surface 2022 of the device under test 202 can be attached to the outer surface of the sampling cavity 102, and the shell surface 2022 can cover the puncture hole 1021. Then, the movement of the puncture module 104 can be controlled so that the needle tip of the puncture module 104 passes through the puncture hole 1021 and pierces the device under test 202, piercing the shell surface 2022 of the device under test 202 and puncturing the air-filled cavity 2021 in the device under test 202. After the air-filled cavity 2021 is punctured, the atmosphere to be tested in the air-filled cavity 2021 escapes from the puncture point, passes through the puncture hole 1021, and enters the sampling cavity 102, thereby realizing the collection of the atmosphere to be tested.

[0050] In one feasible embodiment, the shell surface of the device under test that is in contact with the outer surface of the sampling cavity includes at least the cavity wall of the air-filled cavity and may also include the outer shell of the device under test, that is, it can be a composite layer of the outer shell of the device under test and the cavity wall of the air-filled cavity.

[0051] In one feasible embodiment, each opening of the sampling chamber 102 may be provided with a dynamic sealing module. The opening of the sampling chamber 102 may include at least a puncture hole 1021 and may also include other channels connected to other functional devices, such as a vacuum channel connected to a vacuum pump and a sample inlet channel 1022 connected to an atmosphere detection device. The dynamic sealing module includes at least one of an elastic sealing ring 1102 and a valve. As an example, an elastic sealing ring 1102 can be provided on the sealing area of ​​the puncture hole 1021 provided on the outer surface of the sampling cavity 102, and the sealing area is larger than the puncture hole 1021. In this way, before piercing the shell surface 2022, the shell surface 2022 of the device under test 202 can be pressed against the outer surface of the sampling cavity 102 provided with the puncture hole 1021, so that the shell surface 2022 fits tightly with the elastic sealing ring 1102, thereby forming a sealed channel between the device under test 202 and the sampling cavity 102, and the device under test 202 and the sampling cavity 102 do not need to be connected as one. When replacing the device under test 202, there is no need to disassemble it. Only the pressure on the shell surface 2022 needs to be removed, and the device under test 202 and the sampling cavity 102 can be separated, so that the device under test 202 can be replaced quickly and easily.

[0052] In one feasible embodiment, a dynamic sealing module is provided between the sampling chamber 102 and the puncture module 104. Since the relative position between the puncture module 104 and the sampling chamber 102 may change during the sampling process, the dynamic sealing module between the sampling chamber 102 and the puncture module 104 may be a dynamic sealing connector, which refers to a connector that can achieve a dynamic seal, such as a metal bellows 1101. One end of the metal bellows 1101 is connected to the cavity of the sampling chamber 102, and the other end is connected to the puncture module 104 or the transmission mechanism 106 or the main structure used to secure the puncture module 104. In this way, when the relative position between the puncture module 104 and the sampling chamber 102 changes, the sampling chamber 102 can still remain sealed.

[0053] In one feasible embodiment, the puncture module 104 can move under contact transmission control such as manual control or the motor control module 108, or under non-contact control such as electromagnetic field control.

[0054] In one feasible embodiment, a first valve can be provided on the puncture hole 1021. After the atmosphere to be measured is collected through the sampling chamber 102, the first valve is closed to seal the atmosphere to be measured within the sampling chamber 102. Then, the puncture hole 1021 is connected to the puncture hole 1021 of the atmosphere detection device, and the first valve is opened to transfer the atmosphere to be measured in the sampling chamber 102 to the atmosphere detection device for detection. Alternatively, an injection channel 1022 can be provided on the cavity of the sampling chamber 102. The injection channel 1022 is used to connect the sampling chamber 102 and the atmosphere detection device. In this way, the atmosphere to be measured collected in the sampling chamber 102 can be transferred to the atmosphere detection device for detection through the injection channel 1022.

[0055] In one feasible embodiment, a vacuum channel is provided on the body of the sampling chamber 102, which is used to connect the sampling chamber 102 to a vacuum pump. A second valve is provided on the vacuum channel. After the shell surface 2022 is in contact with the outer surface of the sampling chamber 102 and covers the puncture hole 1021, and before the puncture module 104 pierces the shell surface 2022, the second valve and the vacuum pump are opened. The vacuum pump removes the original gas in the sampling chamber 102 to improve the purity of the subsequently collected atmosphere to be measured. At the same time, a certain vacuum level can be formed in the sampling chamber 102. In this way, after the puncture module 104 pierces the shell surface 2022, the atmosphere to be measured in the gas-filled cavity 2021 can escape into the sampling chamber 102 more quickly and in greater quantities. After the vacuum level in the sampling chamber 102 falls below a preset vacuum level, the second valve and the vacuum pump can be closed. At this time, the second valve is used to isolate and seal the sampling chamber 102.

[0056] In one feasible embodiment, the device for sampling the internal atmosphere of the device may further include a device to be tested 202 fixing device for placing and fixing the position of the device to be tested 202, and may further apply pressure to the device to be tested 202 so that the device to be tested 202 is tightly fitted to the outer surface of the sampling chamber 102, thereby improving the sealing of the device, preventing the loss of the atmosphere to be tested, and increasing the concentration of the atmosphere to be tested in the sampling chamber 102.

[0057] In the above-mentioned internal atmosphere sampling device of the device, a puncture hole 1021 is provided on the cavity of the sampling cavity 102, and a puncture module 104 is provided at a position corresponding to the puncture hole 1021 in the sampling cavity 102, so that the needle tip of the puncture module 104 can extend from the sampling cavity 102 to the outside of the sampling cavity 102 through the puncture hole 1021. In this way, when the shell surface 2022 of the device under test 202 is in contact with the outer surface of the sampling cavity 102 and covers the puncture hole 1021, the needle tip of the puncture module 104 is controlled to extend to the outside of the sampling cavity 102, so as to puncture the shell surface 2022 and puncture the gas in the device under test 202. The air-filled cavity 2021 allows the atmosphere to be tested in the air-filled cavity 2021 of the device to be tested 202 to escape from the puncture point and enter the sampling cavity 102 through the puncture hole 1021. Since the shell surface 2022 is in contact with the outer surface of the sampling cavity 102, the atmosphere to be tested has no other flow path after escaping, so it will all escape into the sampling cavity 102. In this way, the sampling cavity 102 can collect all the escaped atmosphere to be tested, and the volume of the sampling cavity 102 only needs to be able to accommodate the puncture module 104. Therefore, the purity and concentration of the collected atmosphere to be tested can be effectively guaranteed, thereby improving the accuracy of the detection results.

[0058] In an exemplary embodiment, Figure 2 As shown, the device for sampling the internal atmosphere of the device further includes a motor control module 108 and a transmission mechanism 106 . One end of the transmission mechanism 106 is connected to the puncture module 104 , and the other end of the transmission mechanism 106 is connected to the motor control module 108 .

[0059] It should be noted that conventional techniques often employ manual puncture to destroy the package structure of the DUT 202 before sampling. However, the internal structure of the DUT 202 is complex, and manual puncture makes it difficult to precisely control the puncture depth. If the puncture depth is too shallow, the shell 2022 may not be pierced, or the puncture site may be too small, making it difficult for the test atmosphere to escape or requiring a long time. If the puncture depth is too deep, the needle tip may strike other structures within the DUT 202 or even puncture other shell surfaces of the DUT 202, causing leakage of the test atmosphere and making it difficult to guarantee sampling quality. Furthermore, manual puncture requires a high level of operator skill and experience, making it difficult to guarantee sampling efficiency.

[0060] As an example, the control parameter values ​​of the motor control module 108 corresponding to various materials or models of shell surfaces 2022 can be pre-tested. The control parameter values ​​are used to ensure that the shell surface 2022 can be pierced by the puncture module 104 without contacting other parts of the device under test 202. Then, during sampling, the control parameter values ​​corresponding to the device under test 202 can be queried based on the material or model of the shell surface 2022. The motor control module 108 is set based on the queried control parameter values. Then, the motor control module 108 can control the transmission mechanism 106 to drive the puncture module 104 to reciprocate based on the set control parameter values. The control parameter values ​​may include at least one of the motor operating speed, the motor rotation angle, the motor torque, the rotation angle of the puncture module 104, the movement distance of the puncture module 104, and the speed of the puncture module 104. The directions of reciprocating motion of the puncture module 104 include a puncture direction approaching the shell surface 2022 and a retreat direction away from the shell surface 2022. When the puncture module 104 moves along the puncture direction, the needle tip of the puncture module 104 passes through the puncture hole 1021, extends from the sampling cavity 102, pierces the device to be tested 202 outside the sampling cavity 102, and pierces the shell surface 2022 of the device to be tested 202.

[0061] In this embodiment, the motor control module 108 can achieve precise control of the operation of the puncture module 104 puncturing the shell surface 2022, which can not only accurately control the puncture depth and improve the sampling quality, but also save human resources and improve sampling efficiency.

[0062] In an exemplary embodiment, Figure 3 As shown, the device for sampling the internal atmosphere of the device further includes a torque sensor 112 . The torque sensor 112 can be provided on the motor control module 108 to collect the current torque value of the motor during the reciprocating motion of the puncture module 104 .

[0063] It should be noted that since the position of the puncture module 104 is not fixed, the starting point before each puncture of the shell surface 2022 is not necessarily fixed. For example, during the process of the puncture module 104 retreating after puncturing the shell surface 2022, due to human factors or sudden factors such as power outages, the puncture module 104 did not move the entire distance according to the pre-set program, but stopped halfway, or the measurement precision and accuracy of the device decreased. In this case, it is difficult to accurately estimate the distance that the puncture module 104 needs to move to pierce the shell surface 2022 and pierce the air-filled cavity 2021 in the device to be tested 202, and it is difficult to accurately control the puncture depth.

[0064] Among them, in the process of the motor control module 108 controlling the movement of the puncture module 104, the resistance encountered by the needle tip of the puncture module 104 is different, and the torque value of the motor control module 108 is different. The greater the resistance, the greater the torque value. That is, before the puncture module 104 contacts the shell surface 2022, the torque value of the motor control module 108 is small. After contacting the shell surface 2022, the torque value continues to increase with the movement of the puncture module 104. After the puncture module 104 punctures the shell surface 2022, the torque value decreases instantaneously. Therefore, the torque value when the puncture module 104 contacts the shell surface 2022 but does not pierce the shell surface 2022 can be determined in advance through testing as the first torque limit value. The torque value when the puncture module 104 contacts the shell surface 2022 but does not pierce the shell surface 2022 to the time when the shell surface is just pierced can also be determined in advance through testing as the second torque limit value. The first displacement value refers to the displacement value at which the puncture module 104 can pierce the shell surface 2022 by continuing to move after contact with the shell surface 2022. For shell surfaces 2022 of the same material, same size or same model, the first displacement value is the same or similar, and therefore can be determined in advance through testing.

[0065] As an example, when sampling, the first torque limit value, the second torque limit value and the first displacement value corresponding to the device under test 202 can be queried according to the material or model of the shell surface 2022; then, the transmission mechanism 106 is controlled by the motor control module 108 to drive the puncture module 104 to move in the direction close to the shell surface 2022. During the movement, the current torque value of the motor control module 108 can be collected in real time or at intervals through the torque sensor 112, and the relationship between the current torque value and the first torque limit value can be determined. When it is detected that the current torque value exceeds the first torque limit, the transmission mechanism 106 is controlled to drive the puncture module 104 to continue moving along the current movement direction by the first displacement value and then stop moving. Alternatively, the transmission mechanism 106 is controlled to drive the puncture module 104 to continue moving along the current movement direction, and the current torque value is continuously detected during the movement. When the current torque value reaches the preset second torque limit, the movement of the puncture module 104 is stopped. In this way, the movement can be stopped just when the shell surface 2022 is punctured, thereby avoiding collision between the puncture module 104 and other parts of the device under test 202.

[0066] In this embodiment, although the distance that the puncture module 104 needs to move to puncture the shell surface 2022 is difficult to estimate, the first displacement value required to puncture the shell surface 2022 after the puncture module 104 contacts the shell surface 2022 can be determined through testing. Therefore, this embodiment can accurately determine the time when the needle tip of the puncture module 104 contacts the shell surface 2022 by monitoring whether the current torque value of the motor control module 108 exceeds the preset first torque limit. At this time, the transmission mechanism 106 is controlled to drive the puncture module 104 to continue to move the first displacement value along the current movement direction, thereby achieving the purpose of accurately controlling the puncture depth.

[0067] In an exemplary embodiment, the control parameter value further includes a second displacement value, and the second displacement value is greater than the first displacement value or the third displacement value corresponding to the second torque limit value. After controlling the transmission mechanism 106 to drive the puncture module 104 to continue to move along the current motion direction by the first displacement value or controlling the transmission mechanism 106 to drive the puncture module 104 to continue to move along the current motion direction until the current torque value reaches the preset second torque limit value, the motor control module 108 is further configured to:

[0068] The control transmission mechanism 106 drives the puncture module 104 to move a second displacement value in the opposite direction of the current movement direction. After the puncture module 104 moves the second displacement value in the opposite direction of the current movement direction, the test atmosphere flows from the gas-filled cavity 2021 into the sampling cavity 102 .

[0069] Among them, the third displacement value refers to the displacement value moved by the transmission mechanism driving the puncture module from the current torque value being the first torque limit value to the current torque value being the second torque limit value. The displacement value can be recorded and determined during puncture.

[0070] As an example, after piercing the shell surface 2022, in order to allow the atmosphere to be tested to escape from the air-filled cavity 2021 faster, the transmission mechanism 106 can be immediately controlled to drive the puncture module 104 to move a second displacement value in the opposite direction of the current movement direction. Since the second displacement value is greater than the first displacement value, the puncture module 104 can be withdrawn from the rupture on the shell surface 2022 into the sampling cavity 102, so that the atmosphere to be tested can escape from the air-filled cavity 2021 and flow into the sampling cavity 102.

[0071] In one feasible embodiment, the device internal atmosphere sampling device can be used as a sampler of the atmosphere detection device. In this case, the device internal atmosphere sampling device and the atmosphere detection device are connected by a pipeline, and the atmosphere to be tested collected in the sampling chamber 102 is directly transmitted to the atmosphere detection device for atmosphere detection. In this case, if it is necessary to quantify the various components in the atmosphere to be tested, it is necessary to simultaneously test the standard sample and compare the test results of the atmosphere to be tested with the numerical values ​​of the test results of the standard sample to achieve quantification. In this way, the closer the flow rate of the atmosphere to be tested is to the standard sample, the more accurate the test result will be. The amount of the standard sample is usually sufficient, and the flow rate of the standard sample input to the atmosphere detection device will be larger. Therefore, the smaller the space in the sampling chamber 102 to accommodate the atmosphere to be tested, the smaller the obstruction when the atmosphere to be tested flows into the sampling chamber 102, the greater the flow rate of the atmosphere to be tested that can be transmitted to the atmosphere detection device, and the more accurate the test result will be. The puncture module 104 quickly retracts after puncturing the shell surface 2022 to reduce the obstruction when the atmosphere to be tested flows into the sampling chamber 102.

[0072] In this embodiment, the motor control module 108 controls the puncture module 104 to return to the second displacement value after puncturing the shell surface 2022, which can effectively regulate the escape flow of the test atmosphere, thereby improving the accuracy of the test result.

[0073] In an exemplary embodiment, Figure 2 As shown, the device for sampling the internal atmosphere of the device further includes a dynamic sealing module, which includes at least one of an elastic sealing ring 1102 and a metal bellows 1101 .

[0074] Among them, the elastic sealing ring 1102 refers to a sealing ring made of elastic material, which is arranged between the shell surface of the device under test 202 and the sealing area 2022 on the outer surface of the sampling chamber 102. The puncture hole 1021 is located in the sealing area, and the sealing area is larger than the puncture hole 1021. In this way, before piercing the shell surface 2022, the shell surface 2022 can be pressed against the outer surface of the sampling chamber 102 where the puncture hole 1021 is opened, so that the shell surface 2022 is tightly fitted with the elastic sealing ring 1102, and a sealed channel can be formed between the device under test 202 and the sampling chamber 102. The puncture hole 1021 is completely in the sealed channel and will not be connected to the external environment. By providing the elastic sealing ring 1102, the device under test 202 and the sampling chamber 102 do not need to be connected as one. When replacing the device under test 202, there is no need to disassemble it. It is only necessary to remove the pressure on the shell surface 2022, and the device under test 202 and the sampling chamber 102 can be separated, so that the device under test 202 can be replaced quickly and easily.

[0075] The metal bellows 1101 refers to a metal bellows that can expand and contract along the tube diameter direction. One end of the metal bellows 1101 is connected to the cavity of the sampling chamber 102, and the other end is connected to the transmission mechanism 106. In this way, when the transmission device drives the puncture module 104 to move, the metal bellows 1101 can expand and contract accordingly. In this way, when the relative position between the transmission device and the sampling chamber 102 changes, the sampling chamber 102 can still remain in a sealed state.

[0076] In this embodiment, by providing a dynamic sealing module, the flexibility of use of the device can be improved while ensuring the sealing of the sampling cavity 102 .

[0077] In an exemplary embodiment, Figure 4 As shown, a sampling channel 1022 is opened on the cavity body of the sampling cavity 102, and the sampling channel 1022 connects the sampling cavity 102 and the atmosphere detection device, and is used to transmit the atmosphere to be measured collected by the sampling cavity 102 to the atmosphere detection device.

[0078] As an example, after the sampling chamber 102 collects the atmosphere to be measured, the atmosphere to be measured is transmitted to the atmosphere detection device through the sampling channel 1022 .

[0079] In a feasible embodiment, the sampling channel 1022 may also be provided with a flow valve for regulating the flow of the atmosphere to be measured input into the atmosphere detection device and regulating the sealing performance of the sampling chamber 102 .

[0080] In one embodiment, the second displacement of the puncture module 104 after piercing the shell 2022 should be greater than the sum of the distance between the puncture hole 1021 and the entrance of the injection channel 1022, the first displacement, and the thickness of the elastic sealing ring 1102, thereby reducing obstruction to the flow of the test gas into the injection channel 1022.

[0081] In this embodiment, by setting the sampling channel 1022, the internal atmosphere sampling device of the device can be used in conjunction with the atmosphere detection device, shortening the transfer time and transfer steps from sampling to detection of the atmosphere to be tested, reducing the transfer risk, and improving the detection accuracy.

[0082] In one possible implementation, Figure 5As shown, the device internal atmosphere sampling device includes a motor control module and a puncture motor module, wherein the motor control module includes a host computer, a controller, a driver and a sensor, and the puncture motor module includes a sampling chamber 102, a motor, a transmission mechanism 106, a puncture module 104, a metal bellows 1101 and a telescopic coupling 116. The device internal atmosphere sampling device may also include a clamp 114. The device under test (DUT) 202 is secured to the puncture hole (1021) of the sampling chamber (102) via a fixture (114). The interior of the sampling chamber (102) is first evacuated. A vacuum seal is established between the shell (2022) of the DUT 202 and the outer surface of the sampling chamber (102) via an elastic O-ring. A puncture transmission mechanism (106) is installed within the sampling chamber (102). The puncture module (104) is secured to the top of the transmission mechanism (106). A metal bellows (1101) provides a dynamic vacuum seal between the transmission mechanism (106) and the bottom of the sampling chamber (102). The bottom of the transmission mechanism (106) extends outside the sampling chamber (102) and is connected to the motor shaft via a telescopic coupling (116). This allows for axial reciprocating motion in response to the forward and reverse rotation of the motor shaft. A motor control system, comprised of a host computer, controller, driver, and sensors, precisely controls the motor's movements during the puncture sampling process. The overall sampling process is divided into three stages. In the first stage of puncture, the motor drives the transmission mechanism 106 at a preset speed to move toward the device under test 202. The puncture module 104 fixed on the top of the transmission mechanism 106 moves toward the device under test 202 until it contacts the shell surface 2022 of the device under test 202. At this time, the current torque value fed back by the torque sensor 112 built in or external to the motor reaches the preset first torque limit, the motor stops, the first stage of puncture ends, and the current position is recorded. In the second stage of puncture, the motor drives the transmission mechanism 106 at a preset speed to continue moving toward the device under test 202. As the device under test 202 moves in the desired direction, the puncture module 104 punctures the sample. When the position sensor reports that the motor's rotation angle (using the position recorded in the first phase as the zero angle) reaches a preset first angle threshold, the motor stops, ending the second puncture phase and recording the current position. During the third puncture phase, the motor drives the transmission mechanism 106 downward in the reverse direction at a preset speed, and the puncture module 104 retracts the needle. When the position sensor reports that the motor's rotation angle (using the position recorded in the second phase as the zero angle) reaches a preset second angle threshold, the motor stops, ending the third puncture phase. During the needle retraction process, the atmosphere inside the device under test 202 escapes into the sampling chamber 102 due to the pressure differential, completing the sampling process. Among them, the first torque limit of the first stage should ensure that the puncture module 104 can stop quickly after contacting the shell surface 2022, without causing significant deformation or rupture of the shell surface 2022; the first angle threshold of the second stage should be determined according to the specific packaging structure of the device under test 202, so that the needle insertion depth of the puncture module 104 can effectively penetrate the shell surface 2022.The reverse speed value of the motor in the third stage should ensure that the atmosphere to be tested inside the device under test 202 can escape quickly to complete sampling.

[0083] In an exemplary embodiment, Figure 6 As shown, a method for sampling the internal atmosphere of a device is provided. This embodiment uses the method applied to a terminal as an example, wherein the terminal may be, but is not limited to, various detection devices, personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices may be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, projection devices, etc. Portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted devices may be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. It is understandable that the method may also be applied to servers, and may also be applied to systems including terminals and servers, and implemented through the interaction between the terminals and servers. In this embodiment, the method includes the following steps S10-S20. Among them:

[0084] Step S10 : When it is determined that the shell surface of the device under test is in contact with the outer surface of the sampling cavity and covers the puncture hole, the puncture module passes through the puncture hole to puncture the air-filled cavity in the device under test.

[0085] It should be noted that the device internal atmosphere sampling method provided in this embodiment is used to control the aforementioned device internal atmosphere sampling device to sample the atmosphere inside the device under test. The device internal atmosphere sampling device includes a sampling chamber and a puncture module. The sampling chamber has a puncture hole formed therein, and the puncture module is disposed within the sampling chamber, corresponding to the puncture hole.

[0086] Step S20: collecting the atmosphere to be measured that escapes from the air-filled cavity through the sampling cavity.

[0087] In this embodiment, a puncture hole is opened on the cavity body of the sampling cavity, and a puncture module is arranged at a position corresponding to the puncture hole in the sampling cavity, so that the needle tip of the puncture module can extend from the sampling cavity to the outside of the sampling cavity through the puncture hole. In this way, when the shell surface of the device to be tested is in contact with the outer surface of the sampling cavity and covers the puncture hole, the needle tip of the puncture module is controlled to extend outside the sampling cavity, so as to pierce the shell surface and puncture the air-filled cavity in the device to be tested, so that the test atmosphere in the air-filled cavity of the device to be tested escapes from the puncture point and enters the sampling cavity through the puncture hole. Since the shell surface is in contact with the outer surface of the sampling cavity, the test atmosphere has no other flow path after escaping, so it will all escape into the sampling cavity. In this way, the sampling cavity can collect all the escaped test atmosphere, and the volume of the sampling cavity only needs to be able to accommodate the puncture module, so the purity and concentration of the collected test atmosphere can be effectively guaranteed, thereby improving the accuracy of the detection results.

[0091] The torque sensor collects the current torque value of the motor control module during the reciprocating motion of the puncture module;

[0092] When the motor control module detects that the current torque value exceeds the first torque limit, the motor control module controls the transmission mechanism to drive the puncture module to continue moving along the current movement direction by the first displacement value, or controls the transmission mechanism to drive the puncture module to continue moving along the current movement direction until the current torque value reaches a preset second torque limit, wherein the puncture module punctures the air-filled cavity in the device under test after continuing to move along the current movement direction by the first displacement value.
