Detection device for annular magnetic steel

Abstract

The invention discloses a detection device for annular magnetic steel. The detection device comprises an end surface detection device, an alignment module, a grabbing and transferring device, a curved surface detection module and a good product queue module, which are sequentially arranged along the moving position of the annular magnetic steel, wherein the curved surface detection module comprises a rotating device, a curved surface detection device and an identification system. According to the detection device, whether the front and back end surfaces and the curved surfaces of the annular magnetic steel have appearance defects or not can be automatically detected; under the transmission power of a feeding mechanism, the annular magnetic steel moves in a half reclining manner, so that detection of defects of the front and back end surfaces is facilitated, a turnover action is achieved through guide plates, and the structure is simple; the rotating device is adopted for curved surface detection of the annular magnetic steel, multiple pieces of annular magnetic steel are stacked in the axis direction of the rotating device, and a single rotating action is carried out, so that automatic detection of curved surface defects of the annular magnetic steel can be achieved at a time, and the detection efficiency is remarkably improved; and after the detection process is finished, the annular magnetic steel without defects can be orderly arranged along the direction of the circle center axis of the magnetic steel, so that subsequent boxing is facilitated.

Description

technical field [0001] The invention relates to the field of magnetic steel detection, in particular to a detection device for ring-shaped magnetic steel. Background technique [0002] With the rapid development of intelligent manufacturing technology, the traditional labor-intensive manufacturing industry has been severely impacted. The reason is that the cost of labor is getting higher and higher, the use of a large number of labor will cause management difficulties, and the harsh manufacturing environment is easy to affect human health. , especially the highly repetitive and high-intensity manual visual inspection work, is increasingly being replaced by machines. In the field of magnetic material testing, the detection of appearance defects of small flat annular magnetic steel parts involves the detection of both front and back sides and curved surfaces. After working in a normal way, workers are prone to visual fatigue and missed inspections. The quality of manual visua...
