Description

technical field [0001] The invention relates to the field of automatic production of soft magnetic cores, in particular to a high-speed visual inspection device for soft magnetic cores. Background technique [0002] With the rapid growth of demand for various consumer electronics and the rapid development of the soft magnetic metal oxide industry, China has gradually developed into the world's largest producer and exporter of soft magnetic metal oxides. However, the production process of soft magnetic metal oxide workpieces is complicated, and defects such as cracks, broken corners, stains, and excessive dimensional errors will inevitably be introduced. Therefore, the defect detection of soft magnetic workpieces is particularly important. The traditional detection methods include manual detection method, eddy current detection method and penetration detection method. These methods all have the disadvantages of low efficiency, complex detection process and low degree of autom...

However, the production process of soft magnetic metal oxide workpieces is complicated, and defects such as cracks, broken corners, stains, and excessive dimensional errors will inevitably be introduced.

Therefore, the defect detection of soft magnetic workpieces is particularly important. Traditional detection methods include manual detection, eddy current detection, and penetration detection. These methods have disadvantages such as low efficiency, complicated detection process, and low degree of automation. The key dimension information of the workpiece cannot be obtained

Patent 201510787229.9 discloses a multi-station transmission camera mechanism for automatic detection of soft magnetic cores. This mechanism uses intermittent rotation devices to realize the cooperation of detection modules, workpiece calibration modules, and kicking modules. However, this method requires a turntable Intermittent start and stop, unable to meet the detection rate requirement of more than 1200 per minute, and the method disclosed in the literature includes four sets of camera light source systems, which cannot complete the detection and measurement of the six sides of the workpiece
