Description

TECHNICAL FIELD

[0001] The utility model belongs to cylindrical battery manufacturing equipment technical field, especially relates to a cylindrical battery helium detection machine. BACKGROUND

[0002] The primary battery (referred to as cylindrical battery hereinafter) of cylindrical lithium battery is a sealed container containing anode and anolyte. The poor sealing of the battery will cause the battery to leak electrolyte during use, and more seriously, water vapor will penetrate into the electrolyte, which will destroy the insulation performance of the internal electrochemical system of the battery. A small amount of water will cause an abnormal large current during the charging process of the battery, causing abnormal heating, explosion and combustion. The sealing of the battery is related to the safety of the battery and the device using the battery, such as electric vehicles.

[0003] The industry uses helium as a tracer gas for leak detection. The helium is first filled and sealed in the cylindrical battery. When detecting, the cylindrical battery is placed in a sealed cavity and vacuumed by a vacuum pump to form a vacuum cavity. The pressure difference between the inside and outside of the cylindrical battery is formed, and the helium leaks from the possible leak welding, cracks, pores, slag and other places from the inside to the outside. The vacuum pump extracts the vacuum gas in the vacuum cavity that may contain the leaked helium to the helium detector. After a certain period of time, when the speed of the helium extracted from the vacuum cavity by the detection pump to the helium detector is equal to the speed of the helium leaked from the battery to the vacuum cavity, that is, when the detected helium and the leaked helium are balanced, the flow rate of the helium detected per unit time is the helium leakage rate of the cylindrical battery. The sealing of the battery is detected by helium, which is called helium detection.

[0004] The leakage of the sealed container is absolute, and the non-leakage is relative. The qualified standard of the air tightness of the cylindrical battery is that the helium leakage rate is greater than or equal to 9.9*10- 7 Pa·m3 / s at 23 DEG C, and it is judged as unqualified. According to this standard, the unqualified products are detected and removed, so as to ensure that the sealing performance of the battery entering the use is qualified, thereby ensuring the safety performance of the battery entering the use.

[0005] The requirements for the helium detection of the cylindrical battery are:

[0006] (1) The air pressure in the sealed cavity reaches ≦20Pa after 2s of vacuum extraction.

[0007] (2) The air tightness of the vacuum cavity: after the air pressure reaches ≦20Pa, the air pressure rises ≦1Pa / s.

[0008] Therefore, we develop a cylindrical battery helium detection machine to detect the sealing of the cylindrical battery. Utility model content
