Abstract

The invention relates to a steel ball surface defect detection method which comprises the following steps: S1, shooting and storing surface images of qualified steel balls and unqualified steel balls, and establishing a standard image library; S2, shooting a to-be-detected steel ball surface image, and comparing the to-be-detected steel ball surface image with an image in the standard image library; and S3, overturning the steel ball, continuously shooting the to-be-detected steel ball surface image, and comparing the surface image with the standard image library. The invention also relates to a steel ball surface defect detection device, which comprises: a camera used for shooting the to-be-detected steel ball surface; an overturning assembly which comprises a first roller rod and a second roller rod, wherein the end of the first roller rod and the end of the second roller rod are connected with rotating motors used for rotating the first roller rod or the second roller rod correspondingly, the first roller rod and the second roller rod are respectively connected with an air cylinder used for driving the first roller rod or the second roller rod to move in the axial direction, the width of a gap between the first roller rod and the second roller rod is smaller than the outer diameter of a to-be-detected steel ball, and detection efficiency is improved.

Description

technical field [0001] The invention relates to a steel ball surface defect detection method, and also relates to a steel ball surface defect detection device. Background technique [0002] For the screening and classification of surface defects of steel ball blanks, due to the complex surface defects of steel ball blanks after production, especially for steel balls produced by hot rolling process, there are generally connecting ribs, scraping skins, ring grooves, random rotation, covering, Dimples, pits, etc., and due to the particularity of steel ball products, different from disc parts, steel balls are three-dimensional workpieces, and defects may be located in various positions on the entire surface of steel balls. At present, enterprises generally use artificial naked eyes to observe and select The way. However, there may be omissions and negligence in naked eye observation, and there is human subjectivity in quality grading. Different pickers may have different classi...
