Abstract

The invention provides a magnetic tile defect detection and image obtaining system based on machine vision. The magnetic tile defect detection and image obtaining system comprises an inner / outer arc surface grinding deviation detection and image obtaining module, a 1 / 2 outer arc surface other defect detection and image obtaining module, an inner arc surface other defect detection and image obtaining module, an edge surface defect detection and image obtaining module and an end surface detect detection and image obtaining module, wherein the inner / outer arc surface grinding deviation detectionand image obtaining module comprises a first light source and a first camera, the first light source comprises a first left light source and a first right light source, the first left light source andthe first right light source are symmetrical relative to the vertical plane in which the connection line of the straight edges of the magnetic tile is positioned, and form equal acute angles with thevertical plane, the first camera is used for capturing the inner / outer arc surface of the magnetic tile and is positioned above the geometric center of the inner / outer arc surface, and the magnetic tile is positioned in the center of the light source area of the first light source. According to the present invention, with the magnetic tile defect detection and image obtaining system, the problemsof low manual efficiency and easy error generation of the machine sorting in the magnetic tile sorting can be solved, and the automatic magnetic tile detection based on the machine vision is precise.

Description

Technical field [0001] The invention relates to the technical field of mechanical engineering lighting, in particular to a magnetic tile defect detection and phase taking system based on machine vision. Background technique [0002] Magnet tile is a tile-shaped ferrite permanent magnet material, which is widely used in permanent magnet DC motors. Its function is to replace the magnetic winding to generate a magnetic field. It is an important component of permanent magnet motors. It is used in industries such as automobiles, home appliances, and power tools. The field is widely used and the demand is huge. The quality of the magnetic tile has a great influence on the performance of the permanent magnet motor, so the sorting of unqualified magnetic tiles has important economic value.

Problems solved by technology

[0003] At present, the detection of magnetic tile defects mainly relies on workers to distinguish and detect them with the naked eye. The labor intensity is high, the personnel are prone to fatigue, and the false detection rate is high, so it cannot be automated and intelligent. It is difficult to achieve correct sorting due to reasons such as large depth of field, poor imaging effect, and difficulty in obtaining images
