No-clean weld joint detection device used for bent type electronic pipes

The invention discloses a no-clean weld joint detection device used for bent-type electronic pipes. The weld joint detection device comprises a vacuum detection bench. A movable pedestal is configured on the vacuum detection bench. A stand column is arranged on the movable pedestal. A support disc capable of up-down moving along the stand column is installed on the stand column via a lock pin. An alcohol storing box is arranged on the vacuum detection bench. An injector is configured to the alcohol storing box. According to the invention, the injector is used for extracting and injecting alcohol in the alcohol storing box to a sealing end of the pipe body, so the sealing end is covered by the alcohol; then vacuum extraction is performed by the vacuum detection bench; and if the alcohol on the sealing end does not disappear obviously and rapidly, it means that the weld joint detection device is well sealed, and if the alcohol disappears quickly, it means that the weld joint detection device is not well sealed, so the sealing end can be adjusted.
