Problems solved by technology
Usually in the existing technology, image recognition is to collect the surface information of parts from multiple angles, which means that multiple cameras need to be set up to take pictures of the workpiece from multiple angles, or use automated equipment to flip the workpiece, and then take pictures of each surface of the workpiece, the above two The equipment and process required for this kind of situation inspection are relatively complicated
At present, there is no simple automatic inspection and sorting method suitable for cylindrical workpieces

Embodiment Construction
[0024] Reference numerals in the drawings include: guide plate 10 , conveyor belt 11 , push plate 12 , slit 111 , groove 13 , No. 1 camera 21 , No. 2 camera 22 , No. 3 camera 23 , mechanical push rod 31 , connecting plate 4 , Cylindrical workpiece 5, diameter recovery box 61, height recovery box 62, surface defect recovery box 63, frame body 70, stabilizing plate 8.
[0025] combined with figure 1 For the automatic sorting method of cylindrical parts shown, the No. 1 camera 21, No. 2 camera 22 and No. 3 camera 23 all use CCD cameras, No. 1 camera and No. 2 camera use a ring light source, and No. 3 camera uses a dome light source . In step 1, the images of the two bottom surfaces of the cylindrical workpiece 5 are captured at different times by the No. 1 camera 21 and the No. 2 camera 22. In step 2, the images of the captured bottom surfaces are processed and the contours of the images are extracted to calculate the size of the bottom surface image. Contour diameter, step 3, ...

The invention relates to a workpiece detection method, in particular to an automatic sorting method for columnar parts. When rolling columnar workpieces are photographed, the exposure time of a third camera is about 300-1200 microseconds, and the wavelength of light generated by a light source of the third camera is 620-760 nm. In the step 4, pushing plates moving at constant speed are used for pushing the columnar workpieces to roll on a slope. In the step 3, the columnar workpieces are placed in a diameter recovery box of a recovery system. In the step 5, the columnar workpieces are placed in a height recovery box of the recovery system. In the step 6, the columnar workpieces are placed in a surface defect recovery box of the recovery system. The sorting method can be used for detecting the columnar workpieces easily.
Description
technical field [0001] The invention relates to a workpiece detection method, in particular to an automatic sorting method for cylindrical parts. Background technique [0002] In the parts processing industry, one of the indispensable links is to check whether the parts are qualified. The criteria for qualified parts include: whether there are appearance defects and whether there are defects in size (outline dimensions). Appearance defects include: casting defects (air bubbles, unequal end faces), wear defects, rust, etc.; unqualified parts are mainly caused by production technology, production environment and human factors. [0003] In theory, to detect the workpiece, at least six faces of the workpiece must be photographed, and it is possible to have a relatively complete inspection of the workpiece. In the prior art, it is relatively common to use image recognition technology to identify whether a workpiece is qualified. Usually in the prior art, image recognition is t...
