Machine, third camera and the 4th camera are all higher frequency camera.
10. a kind of workpiece, defect detection and elimination method are detected and are picked based on the described in any item workpiece, defects of claim 1-9
Except device, which comprises the following steps:
S1, the workpiece that multiple cylinders are sequentially placed in the transmission device, each workpiece are located between two idler wheels, workpiece
Side is abutted with the surface of two adjacent idler wheels；
S2, the translation component, runner assembly and detection device work, wherein translation component drives workpiece linear transmission, and turns
All roller steerings are consistent in dynamic component, and workpiece rotates under the action of idler wheel, when the first phase of workpiece motion s to detection device
Machine, second camera, third camera and the 4th camera the visual field in, first camera and second camera carry out image to the side of workpiece
Acquisition and defects detection, third camera and the 4th camera carry out Image Acquisition and defects detection to two bottom surfaces of workpiece；
The data of acquisition are transmitted to data processor by S3, first camera, second camera, third camera and the 4th camera, described
Data processor judges that the image of precomputation acquisition whether there is surface defect,
If there are surface defects, as rejected product for the image of acquisition, then component operation is rejected, it is unqualified to push bar promotion at this time
Product are to scrap collecting tank；
If defect is not present in the image of acquisition, continue to transmit backward.
