Air tightness test of camera lens

Camera is used to present video and audio in real time. It can provide more scientific basis for accident handling and positioning, and fully guarantee the safety of our property and life. General cameras should be waterproof, camera lens as the most important part of the camera, its air tightness is also very important. Therefore, consumers have high requirements for its air tightness. If its air tightness is not good, it is easy to enter the water vapor in special weather, resulting in failure, resulting in damage to the internal chip of the camera, and the camera can not be used.

Hiris technology has also done in-depth research on the air tightness of camera lens, and has made good achievements, so this time we will share a case of air tightness detection of camera lens for your reference, hoping to help you.


Three position air tightness detector for hiris technology camera lens

1、 Shape analysis of camera lens

1. The camera lens is a cylinder with small volume and irregular shape. The surface is wrapped with black waterproof shell material. The surface of the camera lens is smooth. The front end is made of a round mirror, and the back side is connected with the turnbuckle of the camera;

1. The sealing degree of the camera lens surface is high, so the detection method of directly filling gas into the interior can not be used for such a shape, and the detection results are prone to deviation due to unfixed.

2、 Break through the difficulties of vehicle camera lens detection

2. Before the detection, Harris technology will customize a mold tooling according to the shape of the car camera lens, and carry out the clamping according to the shape, diameter, size of the lens and the place to be detected;

3. The air tightness tester with three working positions is used for this test. The three working positions can be tested at the same time without any influence on the accuracy and stability of the test. It saves time and reduces the cost of air tightness test;

4. At the beginning of detection, put the camera lens upward into the mold, and the circular hole connected at the lower part downward. At this time, the upper and lower molds are closed to form a closed space, and then connected with our instrument. There is a valve island, air tank and other parts inside the instrument and the program we set. After connecting, press the start button when detecting the wire.

5. During the detection, the instrument will inflate into the camera through the lower circular opening. If the camera lens is not sealed, air leakage occurs. At this time, the leakage value display data in the instrument is larger and larger, and the pressure value drops. At this time, whether the camera lens leaks can be determined, and the instrument test results will also show ng, which means that the air tightness test fails. If the tested camera lens does not leak, the gas in the tooling die will be in a constant state after inflation, the pressure value and leakage value displayed on the instrument are also stable, and the test result of the instrument will display "OK", indicating that the air tightness test has passed.

3、 Advantages of using multi position tightness detector

(1) Save time and cost; The detector can provide three detection channels, 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) Lower equipment cost; The three position tightness tester is controlled by three testing equipment. It only needs one person to operate. It simplifies the manpower for the enterprise and optimizes the capital chain of the manufacturer.

(3) It has strong operability and high efficiency; The tester is also equipped with & quot; Positive and negative & quot; Two pressure forms and eight basic test modes can be selected or combined. Using 24 bit a / D conversion, 32-bit CPU operation, and fully independent development of industrial control operating system, with full touch human-computer interface. Built in RS232 serial port, RJ45 network port, USB communication interface, LTP external I / O control port, support a variety of communication protocols, diversified self-service operation, artificial and intelligent combination, enhance the operability of the device.
