Car cameras require a certain level of waterproofing, because when the camera is in a humid environment, water vapor and dust can easily enter the protective case, causing the device to become foggy, dusty, and damaged.Therefore, manufacturers will conduct air tightness testing on vehicle cameras to determine whether the products meet the waterproof level requirements.This time, Hirays Technology will bring you a detailed vehicle camera air tightness testing case. The equipment used is our independently developed high-precision vehicle camera air tightness tester. The following is a brief introduction to the application cases of this instrument.
one,Car camera sealing process
Most of the existing waterproof and dustproof camera casings are plastic shells or aluminum shells. The head of the waterproof camera is connected to the camera base through threads. The threads are provided with waterproof glue. The front shell and the back shell are welded together using ultrasonic waves to form a sealed environment, leaving no inflatable port to achieve overall sealing.
two,Key points for air sealing testing of vehicle cameras
1. Need to achieve non-destructive testing of vehicle cameras
2. to achieveIPX7Grade waterproof test pressure
3. This car camera has wires, so you need to take into consideration when testing

Four,Introduction to Hair Sealing Technology Vehicle Camera Air Seal Testing
Since the car camera does not have an inflation hole, Hirays Technology uses the indirect detection method. We customize a mold for the car camera to assist in the inspection.The mold is divided into an upper mold and a lower mold. After the two are closed, they can provide a sealed testing environment for air sealing testing. They can also protect the vehicle camera during testing and prevent equipment from being scratched.
After putting the product into the mold, start the detection, and the precision pressure sensor of the air tightness detection equipment starts to work, strictly monitor the air pressure changes in the mold, and control the detected air pressure within a certain range.Finally, after a series of calculations, the gas leakage value can be obtained. Based on the leakage value, the airtightness and performance of the vehicle camera can be detected.IPWaterproof rating.The following is a detailed picture of the air tightness detector testing the vehicle camera.
five,Hirays Technology vehicle camera air tightness tester parameters
In addition to the overall air tightness test, Hirays Technology's vehicle camera air tightness tester can also test the camera lens, casing, wires and other parts with different tooling. Its strong applicability has been used by many manufacturers as the core instrument for air tightness testing in production lines.
