Problems solved by technology

[0002] Many products have certain requirements for airtightness. For example, laser light sources have high laser energy. If the airtightness of the light source is not good, it is easy to absorb dust and adhere to the lens, resulting in a decrease in the brightness of the light source and affecting the life and reliability of the product. , therefore, the tightness detection of the product is particularly important
[0003] At present, the main method of airtightness testing is to put the product into the dust box and check the dust entering the product. The detection of batch products is difficult to be applied in the batch production process of products

Abstract

The invention provides a sealing detection method and system. The system comprises an air inlet pipeline connected with an air inlet of detected equipment, inflation equipment which is connected withthe other end of the air inlet pipeline and is used for inflating the detected equipment, and an air outlet pipeline connected with an air outlet of the detected equipment, wherein the air inlet pipeline and the air outlet pipeline are respectively provided with an air pressure gauge and a air flow meter. Through measuring the air pressure and the flow of the air in the detected equipment and theair pressure and the flow of the air flowing out of the detected equipment from the air outlet, whether the detected equipment passes sealing detection is determined. The method is advantaged in thatthe detection result of each detected equipment can be accurately acquired, and consistency of batch product detection can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of airtightness detection, in particular to a method and system for airtightness inspection. Background technique [0002] Many products have certain requirements for airtightness. For example, laser light sources have high laser energy. If the airtightness of the light source is not good, it is easy to absorb dust and adhere to the lens, resulting in a decrease in the brightness of the light source and affecting the life and reliability of the product. , therefore, the tightness detection of the product is particularly important. [0003] At present, the main method of airtightness testing is to put the product into the dust box and check the dust entering the product. The detection of batch products is difficult to be applied in the batch production process of products. Contents of the invention [0004] The object of the present invention is to provide a leak detection method and system, which are use...
