If the car taillights are not properly sealed, there will be fogging, water accumulation, slow response speed, poor ventilation effect and other carlight problems, resulting in the taillights not being able to be used normally or even being damaged."Exploding lights".Therefore, we need to use professionalThe air tightness detector finds the location of leaks and improves the quality of car lights.So what is the best way to test the air tightness of car lights?Below, Hirays Technology shares its testing experience in this area.
The picture above shows the car taillight that Hirays will test this time. From the picture, we can see that the light is a long strip with screws on it.The waterproof structure of the taillight is divided into two parts. The first one is structural waterproofing, which uses the complex structural design of the car light to achieve the sealing of the car light. The second one is the material waterproofing, which is sealed by glue potting, waterproof film, sealing strips and other methods.In view of the specific conditions of the tail lights, Hirays Technology decided to use indirect testing methods to test the air tightness of the tail lights.
Since the taillight of this car does not have an air inlet, Hirays Technology needs to customize a special mold for it to conduct air tightness testing.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 sealing testing. They also play a role in protecting the taillights during testing and preventing scratches on the taillights.According to the regulations of the automobile manufacturing industry, automobile lamps have a maximum leakage standard. When producing lamps, it is necessary to use professional testing equipment to detect the air tightness of the lamps and find leakage gaps to provide a basis for the modification of the lamps.

Set the detection parameters before starting and inflate the mold indirectly.,, let the instrument fill a certain amount of gas into the mold. The gas will have a pressure stabilization process in the mold. At this time, a certain pressure will be formed around the product. The pressure is monitored through a precise pressure sensor. After a series of calculations, the gas leakage value can be obtained. Based on the leakage value, the air tightness and airtightness of the tail light can be detected.IPWaterproof rating.

five.Introduction to other functions
1. This sealing tester can support leakage testing methods such as leakage testing, obstruction testing, positive pressure testing, and negative pressure testing. It has a wide testing range 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. bring4switch input and8The relay output can be controlled by external sensors and switch buttons, and can control external relays, solenoid valves and other actuators to facilitate full automation of testing.
5. Waterproof tester has200segment 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 use the leakage meter's ownI/OThe interface allows the leak meter to receive control signals from external sensors and control external actuators (relays, solenoid valves, etc.).Thereby automating the testing process.
6. With test data recording function, test data can be downloaded toUdisk and displayed via computer.
7. With barcode scanning function, it can track and record defective products and repair status; host computer function, etc.
