The invention discloses a method and a device for automatically detecting impurities in a health wine. The device comprises a detection wheel disc, a bottle feeding mechanism, a bottle discharging mechanism, a sorting mechanism for removing inferior health wine bottles, an mechanical arm for clamping and overturning health wine bottles, a detection bracket, a camera to shoot images for health wine bottles, a lens, a light source and a microprocessor. The method comprises the following steps: a health wine bottle is introduced into the detection wheel disc, is clamped and overturned by the mechanical arm; an sequence image of the health wine bottle is acquired when the health wine bottle is in an inverted state and keeps uniform motion; the acquired sequence image is located by a computer;whether impurities exist in the health bottle or not is judged; and the inferior health wine bottles are removed by a control sorting mechanism. The device and the method have the advantages of low cost, rapid detection speed, high reliability and high detection accuracy rate and the like.
