Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a workpiece screening device. Background Technology

[0002] Defect detection is a quality control technology that uses machine vision to automatically identify and evaluate defects such as spots, pits, and scratches on the surface of objects. This technology is widely used in industrial fields with strict requirements for appearance, such as metal surfaces, glass surfaces, and electronic components. It mainly uses image processing algorithms combined with multi-light source collaborative imaging systems to enhance the imaging effect of surface defects of different materials through dark field, bright field, and transmitted light illumination methods. After defect detection on the surface of the workpiece, the workpiece needs to be screened and classified in order to distinguish between qualified and unqualified workpieces.

[0003] According to Chinese utility model application number CN202420774383.7, a multifunctional optical screening operating table is proposed. The utility model describes that "through the design of stepper motor one, the rotating shaft can be driven to rotate inside the bent support frame, thereby causing the circular screening table to tilt forward or backward as a whole, so that the workpiece on its top slides forward or backward under the action of gravity, thereby realizing the function of automatically discharging qualified or unqualified workpieces and improving the overall screening efficiency."

[0004] This multifunctional optical screening operating table uses an optical camera to detect defects on the surface of the workpiece. The circular screening table tilts forward or backward to classify and collect qualified and unqualified workpieces. After screening each workpiece, the next workpiece needs to be installed, which is time-consuming and labor-intensive and affects the screening efficiency. Therefore, a workpiece screening device is proposed to solve the above problems. Utility Model Content

Display screen 8 shows the inspection results, as well as the number of qualified and unqualified workpieces. Finally, the external air pump is turned on, causing nozzle 76 to blow air. When a qualified workpiece rotates to the designated position, nozzle 76 blows air to blow the qualified workpiece towards the left feed pipe 72. When an unqualified workpiece rotates to the designated position, nozzle 76 blows air to blow the unqualified workpiece towards the right feed pipe 72. When debris rotates to the designated position, nozzle 76 blows air to blow the debris towards the collection box 73, realizing classified collection. Multiple workpieces can be screened continuously without the need for workpiece installation, saving time and labor and improving screening efficiency.
