    Air leak tester for the amart watch

    2018-12-10

    Testing principle

    Hairuisi sealing tester is a new ,high precision and non-destructive air leak tester .Our air leak tester adopts pressure principle and uses compressed air as the medium to detect leaks. It is a non-destructive testing instrument. The working principle is to apply a certain pressure to the inner cavity or outside of the product to be tested, then close the valve. After a period of stability, measure the change of the air pressure during the detection period and calculate the leakage amount by our precision sensor.This instrument is widely used in the sealing test of open products or sealed products with its high precision and full-featured features.

    ♦Product description 

    The user of this watch is for young children ,so waterproof testing for the chinldren is required .The waterproof rating of this children's watch is IP67 . The following is our testing programme .

     

    Testing point

    Children's watches are electronic products.The testing point mainly USB part and battery part .Through waterproof testing ,The testing result and data can be offered to the watch manufacturer to them to improve the product quality .


     

    ♦The design of testing mold

    Since the testing product don't have Inflatable mouth.Hairuisi Technology needs to customize a suitable mold .The mold is fixed to the tooling to detect the product 's waterproof .The mold is

    divided into upper and lower parts. When the upper and lower molds are closed, a sealed space can be formed. At this time, the instrument will inflate the mold, and the sealed space is

    beneficial for monitoring the change of the air pressure in the watch.

    In addition to waterproof testing of children's smart watches as a whole, we can also test different parts of them with different molds, such as USB interface, charging port, buttons, etc., to

    achieve all-round waterproof detection, breaking through its detection difficulties. 


    ♦Testing process 

    1.Connect the leak tester to the power supply and air supply.At the same time,the fixture and the tester are also connected through the air source,

     so that the our air leak tester can control the fixture.

    2.Acoording to the customer's testing requirements and our test experiments on products in the early stage to set the testing parameters on our air leak tester .

    3.Put the testing product in the mold and press the start button .the fixture will seal the mold and Certain compressed air will be input from our instrument into the mold.

    when input air time finished ,The valve will close and our instrument will measure the change of the air pressure during the detection period and calculate the leakage amount by our precision sensor.

     

    when the testing time is finished ,The testing result (OK or NG )will be shown on our screen .



    ♦Features of our air leak tester 

    1)Large touch screen, intelligent operation system, the graphic UI design based on the detection process,the operation interface is simple and clear, easy to teach and easy to learn.

    2)With the alarm function of qualified and unqualified products, the possibility of artificial misjudgment can be excluded.

    3) It has network function and can be equipped with host computer monitoring software to realize remote management and monitor quality. 

    4)Can select the bar code scanning function and printer, convenient product data management and quality tracing, instrument history records can be as many as 200 thousand and can be exported.
