As a camera used to present video and audio in real time, it can provide a more scientific basis for accident handling and positioning, so that our property and life safety can be fully guaranteed.General cameras must be waterproof. The camera lens is the most important part of the camera, and its airtightness is also very important.Therefore, consumers have particularly high requirements for its air tightness. If its air tightness is not good, water vapor will easily enter during special weather and cause malfunctions, causing damage to the internal chip of the camera and making the camera unusable.
Hirays Technology has also done in-depth research on the air tightness of camera lenses and has achieved good results. So this time we will share a case of air tightness testing of camera lenses for your reference. We hope it will be helpful to you.
Hirays Technology camera lens three-station air tightness detector
1. Appearance analysis of camera lens
1. The camera lens is cylindrical in shape, small in size, and irregular in shape. The surface is wrapped with black waterproof shell material. The surface of the camera lens is smooth. The front end is a lens made of a round mirror, and the back is a turnbuckle that connects the camera;

1. The surface of the camera lens has a high degree of sealing. With such an appearance, the detection method of directly filling the interior with gas cannot be used. It is easy to cause deviations in the detection results due to the inability to fix it.
2. Breakthrough in the detection of vehicle camera lenses
2. Before inspection, Hirays Technology will customize a mold tooling according to the shape of the vehicle camera lens, and clamp it according to the shape, diameter, size, and location to be inspected of the lens;

3. The test this time is a three-station air tightness detector. Using a three-station air tightness detector can realize simultaneous detection of three stations without any impact on the accuracy and stability of the detection. It saves time during detection and reduces the company's air tightness detection costs;

4. When the inspection starts, place the camera lens upwards into the mold, and place the circular hole connected below into the clamping position. At this time, the upper and lower molds are closed to form a closed space, and then connected to our instrument. There is a valve island, gas tank and other components inside the instrument as well as the program we have set. After the connection, press the start button when testing the wire.

5. During the test, the instrument will inflate the inside of the camera through the lower round port.If the camera lens 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.At this time, you can determine whether the lens is leaking, and the instrument test result will also show NG, which means the air tightness test failed.If the tested camera lens does not leak, the gas in the tooling mold will be in a constant state after inflation, and the pressure value and leakage value displayed on the instrument will also be stable. The instrument test result will display OK, indicating that the air tightness test has passed.
3. Advantages of using multi-station tightness detector
(1) Save time and cost; this detector can provide three detection channels during detection, and can detect three camera lenses at the same time. The test speed is three times faster than usual, which is more conducive to saving time and cost.
(2) Equipment cost is lower; the three-station sealing tester is controlled by three testing equipment and requires only one person to operate, streamlining manpower for the enterprise and optimizing the manufacturer's capital chain.
(3) Strong operability and high efficiency; the tester is also equipped with"Positive, negative"Two pressure forms and 8 basic test modes can be selected individually or combined.It uses 24-bit A/D conversion, 32-bit CPU operation, and a completely independently developed industrial control operating system, combined with a full-touch human-computer interaction interface.Built-in RS232 serial port, RJ45 network port, USB communication interface, LTP external I/O control port, supports multiple communication protocols, diversified self-service operations, and combines artificial intelligence with intelligence to enhance the operability of the device.
