Waterproof test scheme of smart Bracelet

Recently, after in-depth business communication with xinzhisheng plastic mold (Shenzhen) Co., Ltd., xinzhisheng hopes that Hailisi technology will provide it with a waterproof test scheme for its smart bracelet. This time, xinzhisheng plastic mold (Shenzhen) Co., Ltd. is to test the sealing between the charging pile and the plastic of the back shell of the smart bracelet, which is required to reach the waterproof level of IP68 50m. The following is a brief introduction to the waterproof test solution.

1、 Design mold and tooling

Considering the problem of product shape, Harris technology needs to design the corresponding mold and tooling before testing. The mold is divided into the upper mold and the lower mold, which can be put into the back cover of the smart bracelet. After the upper mold and the lower mold are closed, it can provide a sealed environment for testing the waterproof level.

2、 Waterproof test process

Before the test, hiris technology will put the back cover of the smart Bracelet into the mold and connect it with our instrument through tooling. The instrument is composed of tester, gas source and tooling. There is a valve island, gas storage tank and other parts inside the waterproof tester and the program we set. At this time, press the start button, the tester will automatically drop and close the mold.

During the test, the instrument will inflate the mold. If the back cover of the smart bracelet is not sealed, there will be air leakage, and the gas will leak to the other end. At this time, the leakage value in the instrument will display more and more data, and the pressure value will drop. At this time, it can be determined that the back shell of the smart bracelet is leaking, and the instrument test results will also show ng. If the back cover of the tested smart Bracelet does not leak, the gas will be in a constant state after inflation, and the pressure value and leakage value displayed on the instrument are also stable. The test result of the instrument will display the word OK, indicating that the back shell of the smart bracelet has passed the air tightness test.


3、 Brief introduction of other functions of intelligent Bracelet waterproof tester

1. The waterproof tester can support leakage test, blocking test, positive pressure test, negative pressure test and other leakage test methods. The test range is wide, and users can choose according to their own test needs.

2. Large size touch screen is used as the human-machine interface, which can easily monitor the test results and set various parameters in the process of waterproof test.

3. It has the alarm function of qualified and unqualified products, which can eliminate the possibility of manual misjudgment and misinspection.

4. With 4-way switch input and 8-way relay output, it can accept the control of external sensors and switch buttons, and can control the external relay, solenoid valve and other executive components, which is convenient to realize the full automation of the test.

5. The waterproof tester has 200 user subroutines. By setting the parameters of the subroutines on the touch screen, the user can connect different subroutines in series to form a test process. Through the I / O interface of the leakage tester, the leakage tester can receive the control signals from external sensors and control the external executive components (relays, solenoid valves, etc.). So as to realize the automation of the test process.

6. With test data recording function, test data can be downloaded to U disk and displayed by computer.

7. With barcode scanning function, it can track and record defective products and repair situation; The function of upper computer.

The above content is the solution analysis of the waterproof test of smart bracelet. The newly customized hiris technology tester has entered the production stage, and it is believed that it will be put into the waterproof test of smart Bracelet in the near future. Thank you for your support and trust.
