AI Technical Summary
During the production process, defective workpieces with large-area defects are difficult to separate from qualified workpieces, leading to problems such as equipment blockage, material jamming, and disordered production.
The first and second array cameras are used together to acquire images of the workpiece surface. Defective workpieces are removed along the conveying mechanism by a high-frequency solenoid valve. Automated separation is achieved by combining trigger sensors and controllers. The image acquisition quality is ensured by the supplementary lighting component, and the defect rate is counted by the weighing device.
It improves the ease of separating qualified and unqualified workpieces, reduces the risk of blockage in production equipment, increases testing efficiency, and allows for real-time monitoring of the defect rate.
