Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection equipment, in particular to a piston ring detection and sorting equipment for automobile. BACKGROUND

[0002] Among the key components of automobile engines, the quality of piston rings directly affects the power performance, fuel economy and emission indicators of the engine. In the production and processing process of piston rings, appearance detection is an important link to ensure product quality. Defects such as scratches, cracks and deformation on the surface of the piston ring are identified by a detection device, so as to realize the sorting of qualified and unqualified products.

[0003] However, in the actual production environment, impurities and dust will inevitably adhere to the surface of the piston ring.
