Magnetic tile on-line detection apparatus, control system and control method thereof

Abstract

The invention discloses a magnetic tile on-line detection apparatus, a control system and a control method thereof. The detection apparatus comprises two sets of magnetic tile on-line detection mechanisms respectively for detections of magnetic tile surfaces; an upender for turn-over of magnetic tiles is arranged between the two sets of magnetic tile on-line detection mechanisms; the two sets of magnetic tile on-line detection mechanisms respectively comprise a frame, a servo motor arranged on the frame and a transmission band driven by the servo motor; the frame is provided with a magnetic tile end face detection apparatus and a magnetic tile cambered surface detection apparatus that are respectively connected to a control system; and the upender and the servo motor are respectively connected to the control system. According to cooperation of cameras and light sources in the magnetic tile end face detection apparatus and in the magnetic tile cambered surface detection apparatus, and setting and adjusting of the control system, the apparatus reaches appropriate light and acquires appropriate images, so as to distinguish good magnetic tile from magnetic tile with surface defects, and realize comprehensive on-line detection of magnetic tile, with high detection efficiency and precision.

Description

technical field [0001] The invention relates to the field of machine vision online detection, in particular to a magnetic tile online detection device, a control system and a control method thereof. Background technique [0002] Magnetic materials have become important basic functional materials in high-tech industries, and have penetrated into all aspects of the national economy. China has become the production and supply center of magnetic materials in the world, and the magnetic material industry has become a basic, pillar and leading industry in China. [0003] The tile-shaped magnets made of permanent ferrite materials (referred to as magnetic tiles) are mainly used in computers, industrial automatic control, magnetos for automobiles, motorcycles, and high-performance magnetos for military industries. At the end of 2010, China's permanent magnet ferrite was about 450,000 tons, and the output of permanent magnet ferrite has exceeded 55% of the global output. According t...

Problems solved by technology

[0005] However, at present, the domestic method of magnetic tile detection is manual detection, there is no automatic detection equipment, and there will be many problems in manual detection. Magnetic tile inspection is a dirty, tiring, and poor job. Workers are prone to fatigue in this environment, which affects the quality of inspection

[0006] At the same time, the color of the material of the ferrite tile itself is close to black, and the detection requires high light angle, light intensity, and camera position, and the contrast between the defect and the intact part is very low, which also makes the existing detection equipment and detection methods Difficult to distinguish between defects and tiles themselves

The application of machine vision inspection in the field of online inspection has already had a lot of successful experience, but due to factors such as the color and shape of the magnetic tile, there is no successful automatic inspection production line at present.
