The lens loosening test device includes a frame, a testing module, and a testing picture card. The testing module includes a base, a rotating drive component, a rotating bracket connected to and driven by the rotating drive component, a knocking component fixed to the rotating bracket, an imaging component, and a fixing component. The fixing component is configured to fix the lens to be tested to enable the lens to be tested to be arranged at top of the imaging component, the knocking component is configured to knock the lens to be tested, and the imaging component is configured to capture an image of the testing picture card by the lens to be tested and determine whether the lens to be tested is loose or not based on the image. The present application can accurately detect whether the lens is loose or not.
