Abstract

The invention discloses a translation type airtight container vacuum degree detection system, comprising: a workbench, a translation stage is arranged in the middle of the work stage, and at least a pair of parallel electrodes are arranged on both sides of the stage; The electrode has a high-frequency electric field applied on the surface to induce glow discharge in the airtight container to be tested; a signal detection analyzer is also provided on the workbench, and the signal detector can capture the airtight container to be tested moving in the airtight container. The glow discharge signal generated in the middle of the electrode. Each airtight container is moved on the translation stage, and when it moves to the middle of the electrode, a glow discharge is generated, and the signal detection analyzer analyzes the vacuum degree of the container and records it into the system, which can realize the airtight container of the assembly line. Detection of vacuum degree.

Description

technical field [0001] The invention relates to a container vacuum degree detection system, in particular to a translation type airtight container vacuum degree detection system. Background technique [0002] Airtight containers are often used to store medicines, food and other substances, and they need to be stored for a long time. Therefore, it is very important to maintain a vacuum state inside the container for the preservation of the internal substances. Therefore, when producing such products, it is necessary to check the vacuum degree in the container. detection. [0003] The prior art generally employs methods such as probes that scan light sources such as infrared by detecting changes in wavelength across the light source in a sealed container. However, this method requires expensive equipment and takes a long time for automated wavelength analysis. Contents of the invention [0004] The invention overcomes the deficiencies of the prior art and provides a system...
