Abstract
The invention relates to an automatic screw detection mechanism. Through a suction screwdriver on a screw suction mechanism, a screw is fed to a circular groove formed by a semicircular groove a of a detection blanking mechanism and a semicircular groove b of a pull block. After the screw is positioned well, an image of the screw is captured by a CCD light source and a CCD, and the appearance of the screw is inspected. The precision of dimensional detection of appearance and length of the screw can be within 0.05mm. After data comparison, if the screw is defective, a detection pull cylinder acts to retreat the semicircular groove a, so that the defective screw falls, and the suction screwdriver discharges again for detection. If the screw is good, the suction screwdriver sucks the detected screw again for subsequent operations. The automatic screw detection mechanism provided by the invention is a high-precision detection mechanism and can be suitable for a precision product automatic screw-driving machine. By the adoption of the mechanism provided by the invention, the screw-driving accuracy can be increased, the product quality can be improved, and the labor intensity of workers can be reduced.
Description
Technical field:
