Car tire pressure detectors are mainly installed inside car tires. If the seal is poor, on the one hand, it will affect the recognition of the sensor chip. On the other hand, the detector works in an environment with high temperature and high humidity in the tire. If the seal is poor, it will cause corrosion of the computer board and accelerate the aging of parts. Therefore, in order to ensure the stable operation of the product, manufacturers will test its waterproofness.This time, Hairis Technology will introduce the waterproof tester for automobile tire pressure detectors we developed. Below is the practical application of the detector.

1. Waterproof technology of automobile tire pressure detector

The waterproofing of automobile tire pressure detectors adopts structural waterproofing and material waterproofing. The tire pressure sensor packaging process has gone through glue filling-ultrasonic-laser welding. Currently, high-end tire pressure sensors use laser welding technology. The strength of laser welding can be judged by sealing test instruments.

2. Waterproof testing requirements and difficult solutions for automobile tire pressure detectors

1. Car tire pressure detectors are precision equipment and require non-destructive testing to avoid damage to the product.However, because the automobile tire pressure detector is small in size and has no inflation port, in order to solve the fixation problem during the detection process, Hairis Technology customized a mold for it.When the upper and lower molds are closed, a closed detection space will be formed. On the one hand, indirect detection is achieved, and on the other hand, the tire pressure detector is protected from unnecessary damage during detection. The following is a mold display.

2. Customers require that multiple products can be tested at the same time to improve testing efficiency and reduce labor costs.Therefore, Hairis Technology recommends that customers customize multi-station automotive tire pressure detector waterproof testing equipment. The multi-station detector is equipped with three waterproof detectors, which can operate the waterproof testing of 6 products at the same time. We designed the detector in a cabinet shape and scientifically designed the instrument space to reduce the floor area and facilitate operation.The following is a display of the waterproof testing equipment of Hairis multi-station automobile tire pressure detector.

3. The waterproof level must be enough to easily cope with high-pressure water guns, waterlogged roads, off-road wading, etc.Here we need to consider the issue of pressure. First, the detector must reach a waterproof level to detect pressure. Second, the car tire pressure detector must not withstand pressure to avoid damage.Therefore, in the process of setting the detection pressure, the precision pressure sensor is particularly important. The precision pressure sensor of the Hairis Technology Waterproof Detector strictly monitors the air pressure changes in the mold and controls the detection air pressure within a certain range.The following is a detailed display of waterproof testing equipment.

The above content is the application demonstration of the waterproof testing equipment of Hairis Technology's automotive tire pressure detector. This instrument has realized single-station and multi-station testing and can be customized according to user needs.At present, this equipment has been put into production testing, and its stable performance and high-efficiency testing have assisted corporate production.
