Battery sealing testing equipment is a device that uses air tightness testing technology to detect battery sealing and sealing performance.Widely used, such as power batteries, electric vehicle batteries, sailboat battery seal detection, etc.

1. Equipment overview.

Battery tightness testing equipment is usually also called air tightness testing equipment, air tightness tester, air tightness testing, air tightness testing, waterproof testing equipment, sealing testing equipment, sealing detector, etc. It is mainly used for sealing testing.Hirays sailing boat battery precision sealing detection system has a built-in high-precision 24-bit A/D conversion module, and the precision sampling analysis module cooperates with the system independently developed by Hirays“IVT”Air tightness control technology enables trace gas leakage detection.It can effectively detect small leaks and analyze sealing performance.

2. General parameters of seal detection instruments:

• Test pressure: 0～500Kpa

• Negative pressure:-80Kpa

• Test accuracy:±0.1pa

• Gas source: 0.4～1000Kpa

• Pressure adjustment accuracy: 0.01Kpa

• Working environment: temperature -20～40℃, humidity 25%～65%

• Power supply: AC 220V

3. Testing principle of air tightness tester

Use compressed air of a certain pressure and a certain volume to inflate the product. If the product has an inflation hole, air is directly supplied to the product's inflation hole. After charging for a certain period of time, the air supply source is cut off, and the pressure sensor inside the air tightness testing instrument is used to monitor the pressure change after the product is inflated to determine the sealing performance of the product; products such asIf there is no inflation hole, you need to design a test mold to wrap the product to simulate the use environment of the product, then quantitatively inflate the surface of the product through the mold, cut off the air source, and use the pressure sensor built in the air tightness test instrument to monitor the pressure changes after the product is inflated. The test diagrams of the two test methods are as follows:

4. The process and method of using air tightness testing seals.

First determine the test standard. Generally, the sailboat battery test uses the IP protection level test standard. Some use IP67 protection level, and some use IP68 protection level. For example, the test air pressure of the IP67 test standard is about 10kpa.First determine the test pressure and protection level requirements.Design a mold according to the product shape. The mold is divided into upper and lower molds. Usually, an automatic tooling is made to control the opening and closing of the upper and lower molds.Put the product into the mold, start the sealing tester, the tooling will merge the mold, and then the instrument will inflate the mold quantitatively and at constant pressure.The precision seal detector begins to detect and analyze the test data.Once the leakage rate of the product is obtained, the sealing performance of the product can be determined based on the leakage rate.

5. This sealing testing equipment can also detect the IP protection level, leakage amount and leakage rate of cameras, wires, home appliances, mobile phones, speakers and other products.

The following are cases where some customers use sealing testing equipment for testing.
