[0002] In modern automotive engine manufacturing, the reliability of engine piping is directly linked to engine performance and service life. Engine piping is a welded assembly of main pipes, branch pipes, and orifice brackets. Joints require perforations to ensure gas flow. However, if piping is not properly perforated or becomes clogged, the piping's essential functions will not be fulfilled, potentially causing engine damage and impacting the vehicle's operational safety.

Given these issues, there is an urgent need for an automated device that can efficiently and accurately detect pipe patency and perform airtightness testing to improve production efficiency and product quality.
