Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection of air tightness parts, in particular to a detection valve plate and a detection test bench. Background Art

[0002] In air tightness tests, a variety of electronic components and pipelines are usually required to ensure the accuracy, reliability and automation of the test. This results in a large number of electronic components and pipelines that need to be connected being piled up inside the test bench and other equipment, causing the internal space of the equipment to be crowded and messy.

[0003] Based on this, the current method is to mark the pipelines and plan the pipeline layout so that they can be regularly set up in the equipment, or use management brackets to fix the messy pipelines. However, the above methods cannot reduce the number of pipelines and the required length, etc. There is still a large number of pipelines piled up, and the piled up pipelines make it difficult to find the problem pipelines in time during inspection and maintenance, resulting in an unstable test environment. Utility Model Content

[0004] The utility model provides a detection valve plate and a detection test bench to solve the problem in the prior art that too many air tightness detection pipelines lead to clutter inside the equipment.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is to provide a detection valve plate, and the detection valve plate includes: a base, a first tube group and a second tube group.

[0006] The base is recessed with a plurality of first air path holes and a plurality of second air path holes along a first direction; the first tube group includes a plurality of first nozzles for connecting to the air inlet of the target product to be tested and a plurality of first air path tubes embedded in the base, wherein the first nozzles are embedded in the first air path holes along the second direction and are correspondingly connected to the first air path tubes.

[0007] The second tube group includes a plurality of second nozzles for connecting to the air outlet of the target product to be tested and a plurality of second air path tubes embedded in the base, wherein the second nozzles are embedded in the second air path holes along the second direction and are correspondingly connected to the second air path tubes.

[0008] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects:

[0009] By arranging the first nozzle and the first air path hole on the base and embedding the first air path pipe, all the pipes of the first pipe group for air intake can be integrated on the detection valve plate, thereby facilitating the layout of the air intake pipe system, reducing the occupation of the internal space of the detection equipment by a large number of pipes, and increasing the space utilization rate. Correspondingly, the second nozzle and the second air path hole are arranged on the base, so that all the pipes for air outlet can be integrated on the detection valve plate, facilitating the systematic layout of the air outlet pipe.

[0010] Among them, the integrated pipeline design can effectively shorten the pipeline length, reduce internal pressure loss and gas leakage. In addition, the connection sections of the pipeline are all located on the detection valve plate, making the maintenance and inspection of the pipeline more convenient.

[0011] In some embodiments, the detection valve plate is further provided with a first pressure sensor, which is connected to the first tube group and is used to detect the intake air pressure value of the target product to be detected.

[0012] By adopting the above technical solution, a first pressure sensor is added to detect and control the intake air pressure value of the first pipe group to ensure that the intake air pressure passing through the detection valve plate is within a safe and effective range.

[0013] In some embodiments, the detection valve plate is further provided with a second pressure sensor, and the second pressure sensor is connected to the second tube group and is used to detect the outlet air pressure value of the target product to be detected.

[0014] By adopting the above technical solution, a second pressure sensor is added to detect and control the outlet air pressure value of the second tube group, so as to facilitate monitoring the pressure value at the output end of the target product to be tested for comparison with the inlet air pressure value, so as to facilitate judgment whether there is leakage in the target product to be tested.

[0015] In some embodiments, the detection valve plate further includes a water sink interface, and the water sink interface is located on both sides of the base along the first direction, wherein the water sink interface is used to connect to an external water sink.

[0016] With the above technical solution, when the air tightness test is currently performed on the target product through a water tank, in order to observe the leaked gas in the water tank, the target product needs to be immersed in the water tank. However, by adding a water tank interface, the water inside the water tank is connected, so that the target product does not need to be immersed in the water tank to directly observe whether bubbles are generated. This also avoids the target product being damaged due to being immersed in water.

[0017] In some embodiments, the detection valve plate also includes a first air-controlled valve group and a second air-controlled valve group, wherein the first air-controlled valve group includes a plurality of first air-controlled valves connected one-to-one with the first nozzles; and the second air-controlled valve group includes a plurality of second air-controlled valves connected one-to-one with the second nozzles.

[0019] In the above technical solution, the pneumatic control valve is used to adjust the gas flow through the pneumatic control valve. The first pneumatic control valve group, the second pneumatic control valve group and the third pneumatic control valve group are set to realize the opening and closing of different gas paths, thereby forming different connection test circuits to detect the air tightness of the target product to be tested.

[0020] In some embodiments, the first nozzle is located between the first air-controlled valve and the third air-controlled valve along the third direction, wherein the first air-controlled valve group, the first tube group and the third air-controlled valve group are arranged in an array along the first direction to effectively utilize the space of the detection valve plate.

[0021] In some embodiments, the detection valve plate also includes a solenoid valve group, which includes a plurality of solenoid valves arranged in an array along the first direction, wherein the solenoid valve group is electrically connected to the first air-controlled valve group, the second air-controlled valve group and the third air-controlled valve group, respectively.

[0022] By adopting the above technical solution, the solenoid valve is used to control the first air-controlled valve group, the second air-controlled valve group and the third air-controlled valve group to realize their automatic control.

[0023] In some embodiments, the first nozzle is interference fit with the first air path hole, and / or the second nozzle is interference fit with the second air path hole.

[0024] By adopting the above technical solution, the interference fit method can effectively prevent the first nozzle from coming out of the corresponding first air path hole and the second nozzle from coming out of the corresponding second air path hole, so as to improve the stability of the pipeline connection.

[0025] In some embodiments, the present application also provides a detection test bench, including a shell, in which the above-mentioned detection valve plate is arranged. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0036] In order to facilitate the subsequent description, before describing the specific structure of the detection valve plate, this application first combines Figure 1 and Figure 2A first direction (X), a second direction (Z), and a third direction (Y) are defined. The first direction is the length direction of the detection valve plate when it is normally placed, such as the X direction; the second direction is the height direction of the detection valve plate when it is normally placed, such as the Z direction; the third direction is the width direction of the detection valve plate when it is normally placed, such as the Y direction. In this application, the first direction (X), the second direction (Z), and the third direction (Y) are perpendicular to each other.

[0037] It can be understood that the mutual perpendicularity in the present application is not absolute perpendicularity, and the approximate perpendicularity caused by processing errors and assembly errors (for example, the angle between two structural features is 89.9°) is also within the range of mutual perpendicularity in the present application.

[0038] See also Figures 1 to 3 As shown, Figure 1 A top view of an embodiment of a detection valve plate provided by the present application is shown; Figure 2 Shows Figure 1 A cross-sectional view of part A; Figure 3 Shows Figure 1 Cross-sectional view of part B.

[0039] In some embodiments, the detection valve plate includes: a base 10 , a first tube group 20 and a second tube group 30 .

[0040] The base 10 is recessed with a plurality of first air path holes 11 and a plurality of second air path holes 12 along a first direction; the first tube group 20 includes a plurality of first nozzles 21 for connecting to the air inlet of the target product to be tested and a plurality of first air path tubes 22 embedded in the base 10, wherein the first nozzles 21 are embedded in the first air path holes 11 along the second direction and are correspondingly connected to the first air path tubes 22.

[0041] The second tube group 30 includes a plurality of second nozzles 31 for connecting to the gas outlet of the target product to be tested and a plurality of second gas pipes 32 embedded in the base 10 , wherein the second nozzles 31 are embedded in the second gas hole 12 along the second direction and are connected to the second gas pipes 32 accordingly.

[0042] In the present application embodiment, combined Figure 1 As shown, the first air path hole 11 and the second air path hole 12 of the base 10 are arranged at intervals along the first direction, wherein the first nozzle 21 and the second nozzle 31 are respectively embedded in the first air path hole 11 and the second air path hole 12. Exemplarily, the first nozzle 21 is interference fit with the first air path hole 11, and the second nozzle 31 is interference fit with the second air path hole 12, so that the first nozzle 21 can be effectively prevented from being disengaged from the corresponding first air path hole 11 and the second nozzle 31 can be prevented from being disengaged from the corresponding second air path hole 12, thereby improving the stability of the pipeline connection.

[0043] Among them, combined Figure 2 As shown, a first air circuit pipe 22 connected to the first nozzle 21 is also embedded in the base 10. Exemplarily, the first nozzle 21 and the first air circuit pipe 22 are connected at the first air circuit hole 11, so that multiple air intake paths of the first tube group 20 are integrated into the detection valve plate, which is convenient for systematic layout of the air intake pipelines.

[0044] Combination Figure 3 As shown, the base 10 is embedded with a second gas line pipe 32 connected to the second nozzle 31, wherein the second nozzle 31 is connected to the second gas line hole 12 at the second gas line hole 12, further realizing that multiple gas outlets of the second pipe group 30 are integrated into the detection valve plate, which is convenient for systematic layout of the gas outlet pipeline. Among them, the present application does not limit the number of the first nozzle 21 and the second nozzle 31, for example Figure 1 Six first nozzles 21 and three second nozzles 31 are shown in the figure, but it can also be set to three first nozzles 21 and one second nozzle 31 according to the interface setting with the detection target product.

[0045] In summary, the detection valve plate effectively reduces the occupation of a large number of pipelines in the internal space of the detection equipment, and increases its space utilization. The embedded first gas line pipe 22 and the second gas line pipe 32 can effectively shorten the length of the pipeline required for detection, reduce internal pressure loss and gas leakage. In addition, the connection sections of the pipelines are all located on the detection valve plate, making the maintenance and inspection of the pipelines more convenient.

A second pressure sensor 41 is added to detect and control the outlet pressure value of the second tube group 30, so as to facilitate monitoring the pressure value at the output end of the target product to be tested, so as to compare it with the inlet pressure value, and facilitate judging whether the target product to be tested has leakage.

[0048] Exemplarily, the plurality of first nozzles 21 of the first tube group 20 are integrated into the first pressure sensor 40 to detect the total intake air pressure value; the plurality of second nozzles 31 of the second tube group 30 are integrated into the second pressure sensor 41 to check the total outlet air pressure value.

The first pneumatic control valve group 23, the second pneumatic control valve group 33 and the third pneumatic control valve group 24 are provided to realize the opening and closing of different gas paths, thereby forming different connection test circuits to detect the air tightness of the target product to be tested.

[0052] In some embodiments, the first nozzle 21 is located between the first air-controlled valve and the third air-controlled valve along the third direction, wherein the first air-controlled valve group 23, the first tube group 20 and the third air-controlled valve group 24 are arranged in an array along the first direction to effectively utilize the space of the detection valve plate.

[0053] In some embodiments, the detection valve plate also includes a solenoid valve group 60, which includes a plurality of solenoid valves arranged in an array along a first direction, wherein the solenoid valve group 60 is electrically connected to the first air-controlled valve group 23, the second air-controlled valve group 33 and the third air-controlled valve group 24, respectively.

[0057] In the embodiment of the present application, when the air tightness test is currently performed on the target to be tested through a water tank, in order to observe the leaked gas in the water tank, the target product to be tested needs to be immersed in the water tank. However, by adding a water tank interface 50, the water inside the water tank is connected, so that the target product to be tested does not need to be immersed in the water tank, and the phenomenon of whether bubbles are generated can be directly observed.
