Description

Technical Field

[0001] The invention belongs to the field of air tightness testing, in particular to an integrated testing structure. Background Art

[0002] In the field of modern product testing, combining circuit connection with specific stress scenarios is an important means to ensure product quality. Currently, among the product testing technologies involving stress scenarios, the more common ones are as follows: Figure 7 The method shown in the figure is to construct a pressurized environment by setting a sealing ring between the product and the tooling. Specifically, this method is to connect the pressure controller to the air inlet of the sealing structure during the test, and the controller supplies air to the sealing structure, thereby applying the required pressure to the product. From the development status of the existing technology, although the pressure test structure based on the sealing ring seal has met the testing needs of some products to a certain extent. However, with the improvement of product testing accuracy requirements and the expansion of testing scale, its shortcomings are becoming increasingly prominent:

[0003] Figure 7 When the test structure is pressurized for the product to be tested, each product needs to be individually equipped with a sealing ring, and when the number of test products is insufficient, a plug seal is required. This multi-point sealing method makes the entire sealing system more complicated, and the number of sealing links increases, resulting in a significant increase in the risk of system leakage. Furthermore, due to the presence of multiple sealing parts, once a leak occurs, it is difficult for technicians to quickly and accurately locate the leak point, which greatly reduces the efficiency of troubleshooting and may cause delays in testing. The presence of multiple sealing parts makes the installation operation complicated. During the installation process, improper operation can easily affect the sealing effect, which in turn has an adverse effect on the reliability of the test results. In summary, the prior art has many shortcomings in product pressure testing, and a more optimized test structure is urgently needed to overcome the above problems in order to meet the efficient and precise requirements of modern product testing. Summary of the invention

[0004] In order to solve the problem of inconvenience in checking air leakage of multiple products, the present invention proposes an integrated test structure. It adopts an integrated test structure, the sealed cavity is welded and provided with an air inlet, connected to the airtight socket through a sealing gasket, and contains a circuit board and a mounting seat. When the number of tested products is insufficient, no plug sealing is required, thereby reducing the risk of leakage.

[0005] In order to achieve the above objectives, this application specifically adopts the following technical solutions:

[0006] An integrated test structure comprises: a sealed chamber, which is a welded part, the left side of which is connected to an airtight sealing socket by a sealing gasket assembly, a pressurized air inlet is arranged on the right side, and the remaining positions are sealed by welding;

[0007] The airtight socket is fixed to the sealed cavity by screws to achieve a sealed connection between the inside and outside of the cavity;

[0008] A test interface for installing the product to be tested is set in the cavity. The test interface is connected to the product to be tested through an airtight socket to realize signal acquisition and pressure testing of the product.

[0009] Furthermore, the inner wall of the sealing cavity is smoothed to reduce installation loss of the sealing ring and improve sealing performance.

[0010] Furthermore, the pressurized air inlet is connected to an external pressure controller for adjusting the test pressure in the cavity.

[0011] Furthermore, the airtight socket is made of corrosion-resistant material to meet the requirements of different testing environments.

[0012] Furthermore, the sealing gasket is made of high temperature and high pressure resistant material to improve the reliability of the sealing cavity.

[0013] Furthermore, the cavity is designed with standardized dimensions and can be adapted to products to be tested of different specifications.

[0014] Furthermore, the sealed cavity includes a circuit board component, and the circuit board component is provided with a plurality of product mounting seats, which can be used to place one or more products to be tested, and the products to be tested are connected to the circuit board component.

[0015] Furthermore, a dust cover is provided outside the pressurized air inlet on the right side of the cavity to protect the cleanliness of the air inlet and prevent blockage.

[0016] Furthermore, the cavity can be quickly vented after the test is completed, and the impact on the product to be tested can be reduced through the designed exhaust channel.

[0017] Furthermore, the cavity can monitor the pressure inside the cavity in real time through a pressure sensor at different test stages, and transmit the data to an external control system.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The integrated test structure of the present invention avoids the need for multiple sealing rings in traditional technology through the design of a sealed cavity with overall welding, thus greatly reducing the risk of leakage. The optimized design of the sealing gasket and the airtight sealing socket further improves the overall sealing performance and ensures the stability of the pressure environment. At the same time, the integrated design integrates multiple sealing points into one structure, simplifies the installation operation, reduces the number of manual intervention steps, and reduces the possibility of reduced sealing performance due to installation errors, thereby significantly improving the convenience and efficiency of the test process.

[0020] By adding smooth treatment inside the sealing cavity, the installation loss of the sealing ring is reduced and the service life of the equipment is extended; at the same time, the use of high temperature and high pressure resistant sealing gaskets and corrosion-resistant airtight socket materials makes the device adapt to complex test environments and ensures the reliability of test data.

[0021] The pressurized air inlet is connected to an external pressure controller, and rapid exhaust can be achieved through the designed exhaust channel. The pressure sensor integrated in the cavity can monitor the pressure in the cavity in real time and transmit the data to the external system, realizing precise control and status monitoring of the pressure environment and improving the intelligence level of the test operation.

[0030] The following describes the implementation of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. In the absence of conflict, the following embodiments and the features in the embodiments can be combined with each other. Among them, the drawings are only used for exemplary illustrations, and only schematic diagrams are shown, not physical drawings, and cannot be understood as limitations on the present invention; in order to better illustrate the embodiments of the present invention, some parts of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product 5; for those skilled in the art, the omission of certain known structures and their descriptions in the drawings is understandable.

[0031] See also Figure 1 , which is a specific structural diagram of the present invention, wherein the sealed cavity 1 is a welded part. During the manufacturing process, the various parts are connected by welding process. Except for the airtight socket 2 assembled and connected by the sealing gasket 3 on the left side and the pressurized air inlet 4 on the right side, the rest of the positions are sealed by welding. This overall welding design effectively reduces the risk of leakage.

[0032] The left side of the sealed cavity 1 is connected to the airtight socket 2 through the sealing gasket 3. The sealing gasket 3 is made of high temperature and high pressure resistant materials and plays an important role in ensuring the reliability of the sealed cavity 1. When assembling, the sealing gasket 3 is placed at the corresponding position on the left side of the sealed cavity 1, and then the airtight socket 2 is aligned with the sealing gasket 3 and the sealed cavity 1 to perform the next connection operation.

[0033] A pressurized air inlet 4 is provided on the right side of the sealed cavity 1, and the air inlet 4 is used to connect to an external pressure controller. During the test, the external pressure controller delivers gas to the sealed cavity 1 through the air inlet 4 to adjust the test pressure in the cavity. In order to prevent the air inlet 4 from being contaminated or blocked when not in use, a dust cover is added to the outside of the pressurized air inlet 4 on the right side of the cavity. In actual operation, when a pressure test is required, the dust cover is removed and the pressure controller is connected; after the test is completed, the dust cover is covered to protect the cleanliness of the air inlet 4.

[0034] See also Figure 2 The overall shape of the sealed chamber 1 is relatively regular, and its external structure design is convenient for connection and installation with other components. Its shape and size are designed according to the test requirements and the layout of internal components, and can provide a stable and sealed environment for the entire test structure.

[0035] The inner wall of the sealing cavity 1 is smoothed. This smoothing has many advantages in practical applications. On the one hand, when installing sealing parts such as sealing rings, it can reduce the installation loss of the sealing rings and avoid damage to the sealing rings during installation or use due to the rough inner wall, thereby extending the service life of the sealing rings; on the other hand, the smooth inner wall helps to improve the sealing performance and reduce the possibility of gas leakage in the inner wall of the cavity.

[0036] See also Figure 3 The airtight socket 2 is fixed to the sealed cavity 1 by screws to achieve a sealed connection between the inside and outside of the cavity. The airtight socket 2 is made of corrosion-resistant material, and the above material selection enables it to adapt to the requirements of different test environments. In the actual installation process, the airtight socket 2 is first aligned with the installation position on the sealed cavity 1, and then it is firmly fixed on the sealed cavity 1 with screws.

[0037] The airtight socket 2 has a connection structure (not shown in the figure), which is used to connect with external equipment and the test interface inside the sealed cavity 1. Its design ensures that the gas and signal inside and outside the cavity can be transmitted safely and stably, while ensuring the sealing performance to prevent gas leakage.

[0038] The airtight socket 2 plays a key connecting role in the entire test structure. It not only connects the inside and outside of the sealed cavity 1, but also realizes the signal collection and pressure testing functions of the product 5 through connection with the test interface.

[0039] See also Figures 4 to 6 A test interface for installing the product to be tested 5 is provided in the cavity, and the test interface is connected to the product to be tested 5 through the airtight socket 2, so as to realize signal acquisition and pressure testing of the product 5. Inside the sealed cavity 1, a circuit board assembly 6 is also included. A plurality of product mounting seats 7 are provided on the circuit board assembly 6, which can be used to place one or more products to be tested 5, and the product to be tested 5 is connected to the circuit board assembly 6. When testing, the product to be tested 5 is placed on the product mounting seat 7 of the circuit board assembly 6, and the electrical connection and pressure testing of the product to be tested 5 are realized through the test interface and the airtight socket 2. The design and layout of the circuit board assembly 6 are determined according to the type of the product to be tested 5 and the test requirements. It can provide a stable electrical connection and signal transmission path to ensure that the signal of the product to be tested 5 can be accurately acquired and pressure can be applied to it during the test process.

[0040] As mentioned above, the pressurized air inlet 4 is connected to an external pressure controller to adjust the test pressure in the cavity. In actual test operation, the external pressure controller sets the corresponding pressure value according to the test requirements, and then delivers gas to the sealed cavity 1 through the pressurized air inlet 4 to make the cavity reach the required test pressure. This pressure regulation method can accurately control the test pressure to meet the test requirements of different products 5.

[0041] The cavity can monitor the pressure in the cavity in real time through the pressure sensor at different test stages, and transmit the data to the external control system. A pressure sensor is installed in the sealed cavity 1. During the entire test process, the pressure sensor continuously collects the pressure data in the cavity and transmits the data to the external control system. The external control system can analyze and process the received pressure data, such as judging whether the test pressure meets the requirements, whether there are pressure anomalies during the test, etc., and perform corresponding operations according to the analysis results, such as adjusting the output of the pressure controller, issuing an alarm, etc., to achieve precise control and status monitoring of the pressure environment and improve the intelligent level of the test operation.

[0042] The cavity can be exhausted quickly after the test is completed, and the designed exhaust channel can reduce the impact on the product to be tested 5. When the test is completed, the gas in the sealed cavity 1 can be quickly exhausted by opening the exhaust channel. The design of the exhaust channel is optimized to avoid excessive impact force or other adverse effects on the product to be tested 5 during the exhaust process, ensuring the integrity of the product to be tested 5 after the test.

[0043] The chamber is designed with standardized dimensions and can be adapted to different specifications of the products to be tested 5. This standardized design has great advantages in practical applications. Whether testing different models of products 5 in the research and development stage or batch testing of multiple specifications of products 5 on the production line, the sealed chamber 1 with standardized dimensions can be easily installed and operated.

[0044] When it is necessary to test products 5 of different specifications, it is only necessary to select appropriate circuit board components 6 and test interfaces for installation and configuration according to the size and test requirements of the product 5, without replacing the entire test structure, which greatly improves the versatility and use efficiency of the test equipment and reduces the test cost.

[0045] During the test, first check the integrated test structure to ensure that the sealed chamber 1, the airtight socket 2, the circuit board components and other components are intact. Check whether the dust cover of the pressurized air inlet 4 on the right side of the sealed chamber 1 is properly covered. If not, cover the dust cover to prevent dust and other foreign matter from entering the air inlet 4. Connect the external pressure controller to the pressurized air inlet 4 of the sealed chamber 1 through a suitable pipe to ensure a firm connection to prevent gas leakage during the test. Confirm that the product mounting seat 7 on the circuit board component inside the sealed chamber 1 is clean and free of foreign matter, and that the pressure sensor is properly connected to the external control system so that the pressure data in the chamber can be accurately monitored and transmitted.

[0046] According to the test requirements, select the product to be tested 5 of appropriate specifications. Since the cavity is designed with standardized dimensions, it can adapt to the products to be tested 5 of different specifications, and place the product to be tested 5 on the product mounting seat 7 on the circuit board component inside the sealed cavity 1. Ensure that the product to be tested 5 is in good contact with the test interface on the circuit board component so that signal acquisition and pressure testing can be achieved later.

[0047] Turn on the external pressure controller and slowly inject gas into the sealed cavity 1 through the pressurized air inlet 4. During the process of injecting gas, the pressure controller will gradually increase the pressure in the cavity according to the preset test pressure value. The pressurized air inlet 4, the airtight socket 2, and the sealing gasket 3 of the sealed cavity 1 work together to ensure that the gas will not leak during the pressurization process. The pressure sensor in the cavity monitors the pressure in the cavity in real time and transmits the pressure data to the external control system. The external control system determines whether the pressure in the cavity has reached the preset test pressure value based on the received data. When the preset pressure value is reached, the pressure controller stops injecting gas into the cavity.

[0048] After the test pressure is reached in the sealed cavity 1, the pressure is maintained for a period of time, which is usually determined according to the test standard of the product 5. During this period, the pressure in the cavity is continuously monitored by the pressure sensor. If the pressure in the cavity remains stable within the specified time without obvious pressure drop, it indicates that the air tightness of the product 5 to be tested is good. If the pressure drops, there may be a gas leak, which needs further investigation.

[0049] When the air tightness test is completed, the sealed cavity 1 is quickly vented through the designed exhaust channel. The exhaust channel can reduce the impact of the exhaust process on the product to be tested 5 and avoid damage to the product to be tested 5 due to exhaust. During the exhaust process, the pressure sensor continues to monitor the pressure in the cavity until the pressure in the cavity returns to the normal atmospheric pressure level. After the exhaust is completed, open the sealed cavity 1 and remove the tested product 5 from the product mounting seat 7 of the circuit board component. Check and organize the integrated test structure. If there are test tasks in the short term, keep the equipment connected; if no test is to be performed in the short term, remove the connecting pipe of the pressurized air inlet 4 and cover it with a dust cover to ensure that the equipment is in good condition the next time it is used.

[0050] Through the above process, the integrated test structure of the present invention can efficiently and accurately complete the air tightness test of the product 5, and in the entire test process, the reliability of the test and the stability of the equipment are ensured through the synergistic effect of various components.

[0051] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
