Title:
MULTI-INSPECTION AND MULTI-STEP GAS LEAK DEFECT INSPECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/006452
Kind Code:
A1
Abstract:
The present relates to a gas leak defect inspection system. The present invention provides a gas leak defect inspection system that is formed in a structure that only supplies compressed air to an object to be inspected and does not recover the air again, such that since a plurality of objects to be inspected can be connected in parallel through a multi-manifold, it is possible to simultaneously inspect a plurality of objects to be inspected for gas leak defects during a single inspection operation, and when inspecting the objects to be inspected for gas leaks, it is possible to perform the inspection under a plurality of target pressure states in consideration of the use environment of the objects to be inspected rather than performing the inspection under a single target pressure state, thereby enabling a more accurate inspection. The order of target pressures can be specified, such that compressed air under a plurality of target pressure states can be smoothly provided. It is possible to more accurately simulate the actual use environment of the objects to be inspected, such that the accuracy of a gas leak inspection result can be improved, and a single inspection cycle, in which an inspection is performed under a plurality of target pressure states, is repeated automatically, such that inspection accuracy can be further improved.
