Abstract
A screw detection device is configured to detect screws and has a device base with a controlling module, a carrying mechanism, a top visual-detection mechanism and a lateral visual-detection mechanism mounted inside. A screw is fed into the device base and is carried on two guide-rail assemblies of a carrying rail of the carrying mechanism. A top visual-detection camera of the top visual-detection mechanism and a lateral visual-detection camera of the lateral visual-detection mechanism take photographs of the screw on the carrying rail. The controlling module determines whether the screw is defective based on the photographs and controls a classifying assembly to discard a defective screw. The controlling module automatically controls the carrying rail, the top visual-detection camera and the lateral visual-detection camera, letting the screw detection device meet different-size screws' detection needs. Therefore, manual adjustments are unnecessary, reducing adjusting time and reducing errors from adjusting the device.
