Description

Technical Field

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

[0002] Fastener screening devices are equipment that use nuts and bolts to compare and judge the quality of fasteners based on the comparison structure and then separate them. The advantages of fastener screening devices are that they can improve production efficiency, reduce labor costs, and improve product quality and safety. Through automated detection and sorting processes, the error rate of manual operation can be greatly reduced, and the consistency and stability of products can be improved.
