Abstract

The invention discloses a device for detecting the tightness of a flexible packaged article, comprising: a detection chamber, a vacuuming device capable of evacuating the detection chamber, and a device for real-time and continuous detection of the thickness of the flexible packaging article in the detection chamber during the vacuuming process. Laser thickness measurement system, and identification system for automatic judgment of tightness. The device for detecting the tightness of the flexible package article of the present invention has the advantages of defect quantification, defect location, high sensitivity, and accurate detection of tiny air leakage. The sealing detection device adopts optical measurement system, software automatic recording and judgment integration technology, and is suitable for high-efficiency and automatic online continuous production detection. In addition, the invention also discloses a method for detecting the tightness of a flexible package.

Description

technical field [0001] The invention relates to a detection device and a detection method for the airtightness of soft packaging articles. Background technique [0002] The packaging material of flexible packaging batteries (such as flexible packaging lithium-ion batteries) is generally a layer of 60-150 micron aluminum-plastic composite film, which is used to vacuum-seal electrode materials and electrolytes to isolate them from the atmosphere. Any damage to the flexible packaging bag will cause outside air to enter the electrolyte and pole pieces, resulting in electrolyte leakage and inflation. In the use of flexible packaging batteries, gas inflation and liquid leakage will not only greatly shorten the life of the battery, but may also damage the entire electrical appliance. Therefore, preventing gas inflation and liquid leakage is an important issue for flexible packaging batteries. [0003] Commonly used methods for testing the airtightness of flexible packaging batteri...
