Magnet appearance defect detection equipment is a high-precision automated inline inspection system used mainly for appearance and dimensional defect detection of magnetic materials, such as NdFeB magnets.
The equipment can automatically perform functions including metal ring defect inspection on the lens, dimension measurement, automatic loading, and automatic unloading. It replaces manual inspection by rapidly identifying a variety of appearance defects, including but not limited to chipping, indentations, yellow spots, color variation, contamination, scratches, bubbles, and raised bumps. At the same time, it measures dimensional parameters such as perpendicularity, parallelism, corner radius, length, width, and thickness to ensure product quality stability and consistency.
This equipment is widely used in production quality control of NdFeB magnetic materials. Through high-precision inspection, defective products can be identified and removed in a timely manner. It can also be applied to appearance and dimensional inspection of other magnetic materials.
Key features include a glass rotary table design with multiple inspection stations, allowing simultaneous detection at different positions and improving inspection efficiency. Each station can independently perform defect detection and dimensional measurement. The system is equipped with ultra-bright LED units to provide sufficient illumination, ensuring clear images and reliable identification of small surface defects. Built-in data storage records inspection results for quality evaluation and process optimization. The equipment automatically sorts OK and NG products based on inspection results, reducing manual intervention and improving production consistency. The minimum detectable defect size is 5 μm. A vibratory bowl feeder is used for automatic loading, and air blow-off is used for automatic unloading, forming a fully automated inspection process.
For precision positioning fixtures, rotary glass tables, or non-standard mechanical parts used in such inspection systems, Hansheng Automation provides custom machining services based on customer drawings.
