Detection scheme of car camera lens

To achieve good waterproof effect, the car camera lens is basically sealed as a whole, but the wire part is not waterproof, which brings challenges to waterproof detection. Because the traditional water immersion detection method is not suitable for the waterproof detection of vehicle camera lens, on the one hand, the wire leakage is likely to damage the internal parts, on the other hand, the pressure of water immersion method can not meet the test pressure requirements of ipx7 waterproof. As a result, Harris technology has developed a waterproof detection scheme for the new car camera



Demonstration of waterproof detection scheme for camera lens


This new vehicle camera lens waterproof detector uses compressed air as the detection medium and pressure drop as the test method for waterproof detection. The vehicle camera lens non-destructive waterproof detection is realized, and the problem that the pressure of traditional water immersion method is not up to the standard is also solved. Improve the detection accuracy of the waterproof performance of the camera, so as to improve the reliability of the camera products, increase its safety factor, and ensure its service life.

In order to achieve high-precision waterproof detection, this equipment only leaves a very small internal space (1.5cc), which can maximize the stability and reliability of the test. And equipped with imported high sensitive pressure sensor, can detect the leakage of 0.1pA, fully meet the requirements of vehicle camera lens waterproof test

In addition, we hope the instrument can meet the production demand of automation. We have added "positive and negative" pressure forms and 8 Basic test modes for this instrument, which can be selected individually 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, and increase the remote control function, real-time monitoring of product data.


The intimate function of hiris technology vehicle camera lens waterproof detector has been recognized by many manufacturers, so this vehicle camera waterproof detector has been put into a large number of production testing.
