After the waterproof camera has undergone the waterproofing process, it needs to be tested for sealing by a sealing tester to monitor whether the overall sealing of the camera reaches the corresponding waterproof level and sealing requirements.Therefore, today, Hirays Technology uses an example to show you the camera sealing test, hoping to provide you with a reference for solving the problem of camera sealing testing.

1. Display of Hirays camera sealing tester

Hirays camera sealing tester is divided into three parts: tester, air source, and tooling.Because the tester, air source, and tooling are self-contained, they cooperate with each other during the test but do not affect each other, which improves the accuracy of the sealing test.

2. Parameters of Hirays camera sealing tester

The equipment is available in three models, which can meet the sealing testing standards required by different cameras. It has complete interface and data transmission functions to achieve diversified operations and testing records.

3. Working principle of Hirays camera sealing tester

This camera sealing tester of Hirays Technology uses compressed air for testing, and cooperates with the pressure drop method detection principle to detect changes in gas pressure and volume through equal air intake, pressure stabilization, detection, and monitoring. Finally, the precision tester PLC performs a series of sampling, calculation, and analysis to obtain the leakage rate, leakage value, etc.

4. Operation steps of Hirays camera sealing tester

Before the test, due to the overall sealed structure of the camera without an inflatable port, we will customize a specific mold for the camera to assist in the sealing test. The camera will be placed into the mold. After the upper and lower molds are closed, a sealed inspection space will be formed to solve the inspection problems caused by the structure of the camera. In addition, the mold can also protect the camera from damage during inspection.

When the detector is started, the tooling connected to the mold injects a certain volume of gas into the mold through the air source. When the detected air pressure is reached, the air supply is automatically cut off and the pressure is stabilized.During voltage stabilization, we can clearly see the data changes of the detector, first fast, then slow, and then leveling off.If the camera is not sealed and air leakage occurs, the leakage value displayed in the instrument will become larger and larger, and the pressure value will decrease at the same time.If the tested camera does not leak, the gas will be in a constant state after inflation, and the pressure and leakage values ​​displayed on the instrument will also be relatively stable.

Finally, the pressure sensor can calculate the gas leakage value through a series of calculations based on changes in air pressure. Based on the leakage value, the camera sealing and IP waterproof level are detected. The following is a detailed picture of the detection.

5. Basic functions of Hirays camera sealing tester

1. This waterproof tester can support leak test methods such as leak test, obstruction test, positive pressure test, negative pressure test, etc. The test range is wide, and users can choose according to their own testing needs.

2 , Using a large-size touch screen as the human-machine interface, you can easily monitor the test results and set various parameters during the waterproof test process.

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

4 , with 4-channel switch input and 8-channel relay output, it can be controlled by external sensors and switch buttons, and can control external relays, solenoid valves and other actuators, conveniently realizing full automation of the test.

5 The waterproof tester has 200 user subroutines. By setting the parameters of the subroutine on the touch screen, the user can connect different subroutines in series to form a test process, and through the I/O interface of the leakage meter, the leakage meter can accept control signals from external sensors and control external actuators (relays, solenoid valves, etc.).Thereby automating the testing process.

6. It has a test data recording function, and the test data can be downloaded to a USB flash drive and displayed on the computer.

7. It has barcode scanning function, which can track and record defective products and repair status; host computer function, etc.
