[0035] In the embodiment of the present application, when it is necessary to perform air tightness test on the product 20 to be tested, the product 20 to be tested can be placed between the two flexible support layers 10, and then the first clamping member 11 is used to clamp the edges of the two flexible support layers 10, so that a sealed cavity can be formed between the product 20 to be tested and the flexible support layer 10. Then, the vacuum pump 12 is used to evacuate the cavity, so that a negative pressure environment can be formed in the cavity. By detecting the pressure of the cavity by the pressure detector 13, it can be determined whether the air tightness of the product 20 to be tested meets the requirements. The detection platform described in the embodiment of the present application can perform air tightness test without tearing off the release paper of the product 20 to be tested, and the product after the test does not affect the use, and the test loss is small and the efficiency is high. Moreover, a series of cumbersome steps of manually tearing off the release paper, pasting, connecting tools such as the pressure gauge and the vacuum pump, and dismantling can be avoided, so as to achieve non-destructive and rapid detection.

[0036] Specifically, the material of the flexible support layer 10 may include but is not limited to at least one of flexible materials such as silicone and rubber, and the embodiment of the present application does not specifically limit the material of the flexible support layer 10. In practical applications, the flexible support layer 10 can be used to simulate the skin environment. In this way, by forming a sealed cavity between the flexible support layer 10 and the product to be detected 20 and forming a negative pressure environment in the cavity, the real environment in which the product to be detected 20 contacts the user's skin can be simulated, so as to further improve the accuracy of the airtightness detection of the product to be detected 20.

[0037] In practical applications, a suction port may be provided on the product to be detected 20, and the suction pump 12 is connected to the suction port through the plug hole 101 to perform a suction operation on the cavity between the product to be detected 20 and the flexible support layer 10. Usually, the suction port is usually arranged in the central area of ​​the product to be detected 20, and correspondingly, the plug hole 101 on the flexible support layer 10 can also be arranged in the central area, so that the suction pump 12 can be better connected to the suction port of the product to be detected 20.

[0038] Optionally, the detection platform may further include: a second clamping member 14, the second clamping member 14 is connected to the flexible support layer 10 and is arranged around the plug hole 101, and the second clamping member 14 can be used to clamp the two flexible support layers 10 with the plug hole 101. In practical applications, the second clamping member 14 can be used to clamp the flexible support layer 10 at the plug hole 101 to avoid air leakage at the plug hole 101, further improve the sealing effect of the cavity formed between the product 20 to be detected and the flexible support layer 10, thereby facilitating further improvement of the detection accuracy of the airtightness detection of the product 20 to be detected.

[0039] Optionally, the first clamping member 11 and the second clamping member 14 are both electromagnetic clamping members, which can clamp the two flexible support layers 10 and the product to be detected 20 when powered on, and the implementation method is simple and the response is fast.

[0040] In some optional embodiments of the present application, the electromagnetic clamping member may include an iron core and an electromagnetic member, wherein the iron core is connected to one of the two flexible support members, and the electromagnetic member is connected to the other of the two flexible support members, and the iron core and the electromagnetic member are arranged opposite to each other, and when the electromagnetic member is energized, the iron core and the electromagnetic member are electromagnetically adsorbed and connected to clamp the two flexible support layers 10.

When the first electromagnetic member 11 is energized, due to the electromagnetic adsorption between the first electromagnetic member 11 and the first iron core 112, the edges of the two flexible support layers 10 and the product to be detected 20 may be clamped, so that a sealed cavity is formed between the product to be detected 20 and the flexible support layer 10.

[0042] Similarly, the second clamping member 14 may include a second iron core 142 and a second electromagnetic member 141, wherein the second electromagnetic member 141 may be connected around the plug hole 101 of the upper flexible support layer 10, and the second iron core 142 may be connected to the lower flexible support layer 10 and arranged opposite to the second iron core 142. When the second electromagnetic member 141 is energized, due to the electromagnetic adsorption effect between the second electromagnetic member 141 and the second iron core 142, the two flexible support layers 10 and the product to be detected 20 may be clamped, so that a sealed cavity is formed between the product to be detected 20 and the flexible support layer 10, so as to avoid air leakage from the plug hole 101, and further improve the sealing effect of the cavity formed between the product to be detected 20 and the flexible support layer 10.

[0043] like Figure 2 As shown, the iron core and the electromagnetic member are both annular members; wherein the first iron core 112 in the first clamping member 11 and the first electromagnetic member 11 are connected to the edge of the flexible support layer 10; the second iron core 142 and the second electromagnetic member 141 in the second clamping member 14 are arranged around the plug-in hole 101. In practical applications, by arranging the iron core and the electromagnetic member into annular shapes, the product to be detected 20 and the flexible support layer 10 can be sealed from all around the product to be detected 20 and the plug-in hole 101, so as to further enhance the sealing effect of the cavity formed between the product to be detected 20 and the flexible support layer 10.

[0044] Optionally, the iron core and the electromagnetic component are both bonded to the flexible support layer 10 to achieve reliable connection between the iron core, the electromagnetic component and the flexible support layer 10.

The embodiment of the present application does not specifically limit the connection method of the iron core and the electromagnetic component on the flexible support layer 10.

[0046] Optionally, the first clamp 11 and the second clamp 14 are both mechanical clamps, which may include but are not limited to a manipulator, a mechanical caliper, an air pump connecting push rod, a multi-point screwing and clamping mechanical structure, etc. The specific content of the mechanical clamp may not be limited in the embodiment of the present application.

In a specific application, a control circuit may be provided in the controller, and the control circuit may work with the air pump 12, the first clamp 11 and the second clamp 14 in a preset order. For example, the control circuit may first control the first clamp 11 and the second clamp 14 to clamp the flexible support layer 10 and the product to be detected 20 to form a cavity between the product to be detected 20 and the flexible support layer 10. Then, the air pump 12 is controlled to perform an air extraction operation on the cavity to form a negative pressure environment in the cavity to achieve air tightness detection of the product to be detected 20.

[0048] Optionally, the detection platform also includes a touch button, and the controller is electrically connected to the touch button. The controller can be used to control the vacuum pump 12, the first clamping member 11 and the second clamping member 14 to start or stop working in response to the operation on the touch button, so as to achieve one-button start and stop, thereby further improving the efficiency of the detection platform in detecting the product 20 to be detected.

[0049] Optionally, the pressure detector 13 may be a pressure gauge, and the detection end of the pressure gauge may extend into the cavity formed by the product to be detected 20 and the flexible support layer 10 to detect the pressure in the cavity. Since the pressure gauge can directly read the pressure in the cavity, the operator can intuitively read the pressure in the cavity.

[0050] In summary, the detection platform described in the embodiments of the present application may at least include the following advantages:

[0051] In an embodiment of the present application, a sealed cavity can be formed between the product to be tested and the flexible support layer by placing the product to be tested between the two flexible support layers and clamping the first clamping member at the edges of the two flexible support layers.
