Since car cameras are exposed outdoors for a long time, they are often exposed to wind and rain. When washing the car, they also face the impact of strong pressure water cannons.Therefore, it is very necessary for car cameras to have good waterproof performance.Hairuisi supplies waterproof testing equipment and related equipment to various types of vehicle camera manufacturers.

The picture below is one of our customers’ car cameras.At present, cameras generally use sealing rings to achieve product sealing.needAir tightness testingThe parts are usually the camera lens, waterproof sealing ring, and wiring harness. Cameras with wiring harnesses need to seal the wires on the jig.

Hairis air tightness testing equipment uses compressed air as testing equipment, so whether it has an inflation port will be considered for all tested products.For products with an inflation port, the direct test method of direct inflation can be used for testing.For products without an inflation port, it is necessary to make a mold for the product according to its shape, place the product in the mold, and fill the mold with a certain pressure of test gas to simulate the state of the product in water.Use our pressure sensor and display to observe the changes in gas pressure in the mold in real time to determine whether the product is leaking (to determine whether the product is waterproof)

Compared with traditional waterproof detection methods, Hairisi's waterproof detection equipment has more advantages than traditional waterproof detection methods:

1. The detection medium is air: air will not cause secondary damage to the product or the camera. Even if the product test result fails, it can be directly repaired.For traditional products that are tested with water, the water will directly enter the interior of the defective product, making repairs difficult.

2. The steps of traditional detection methods are relatively complicated. For example, if a leak is found in a car camera by soaking it in water, the camera needs to be dried first before maintenance can be carried out, which takes too long and is inefficient.

3. In traditional waterproof detection methods, the standard for judging water leakage is mainly based on the operator's naked eye observation, which often leads to misjudgment and cannot effectively control defective products.

Hai RuisiAir tightness testing equipmentIt has overcome the shortcomings of traditional waterproof testing methods and solved waterproof testing problems for many companies. The air tightness waterproof testing equipment developed by our company has been used in thousands of factories. It does no damage to the product and has high testing efficiency. We can produce multi-channel, multi-station air tightness testing equipment according to customer production needs. At the same time, the testing accuracy can reach 1pa. Even small leaks can be accurately sensed on our instruments and displayed intuitively on the display.
