Embodiment
[0037] Such as figure 2 As shown in FIG. 1 , it is a structural schematic diagram of the screw internal oblique tooth defect detection system of the present invention. The defect detection system 100 of screw internal oblique teeth includes a transparent or translucent pallet 160 for placing the screw G, which can be a turntable or a belt, and the defect detection system also includes
[0038] The lighting unit 110 is at a fixed distance X1 from a surface B1 of the supporting board 160 , of course, the distance X1 between the lighting unit 110 and the supporting board 160 can be changed as required. The lighting unit 110 is used to irradiate light to the supporting plate 160 and the screws G to be inspected placed thereon. The lighting unit 110 may include one or more light sources, so that the lighting unit 110 can irradiate light to the transparent or translucent supporting plate 160 and the screws to be detected placed thereon on the entire plane range of the transparent ...

The invention relates to a detection system for the defects of inclined teeth in screws, which comprises a supporting plate (160) for laying the screws, a lighting unit (110), a reflecting unit (120), an imaging unit (130), an image establishing module (140) and an image processing module (150), wherein the lighting unit (110) is away from one surface B1 of the supporting plate (160) for a fixed distance X1, the reflecting unit (120) comprises at least a group of reflectors which are away from the other surface B2 of the supporting plate (160) for a fixed distance X2, the imaging unit (130) is away from the surface B2 of the supporting plate (160) for a fixed distance X3 and is positioned above the reflecting unit (120), the image establishing module (140) is connected with the imaging unit (130), and the image processing module (150) is connected with the image establishing module (140). The invention also discloses a detection method for the defects of inclined teeth in screws. The detection system for the defects and the method provided by the invention can detect whether the defects of the inclined teeth occur in the inner screw teeth of the screws and can judge the severity degree of the existing defects of the inclined teeth.
Description
technical field [0001] The invention relates to a defect detection system and a detection method thereof, in particular to a screw internal oblique tooth defect detection system and a detection method thereof, belonging to the field of optical detection. Background technique [0002] The internal oblique tooth defect of the screw refers to the situation where the axis of the internal thread of the screw is inclined during the processing. Such as figure 1 Shown is a schematic cross-sectional view of the screw. in, figure 1 (a) is a cross-sectional view of a screw without internal oblique teeth defects. At this time, the central axis OO' of the screw is perpendicular to the horizontal direction, and the angle between the internal thread 1 and the horizontal direction is A1, and this value is regarded as this specification screw The theoretical value of the inclination angle of the internal thread (usually, the theoretical value is replaced by a certain value range during ac...
