[0002] In modern industrial production, water pumps are important equipment for fluid transportation, and their performance and reliability directly affect the operating efficiency and safety of the entire system. One of the core components of a water pump is the bearing, which plays a key role in supporting the rotating shaft, reducing friction, and maintaining smooth operation. Therefore, quality control of the bearing is crucial to ensure the overall performance of the water pump.

[0003] During the installation and detection of bearings, correctly identifying the reference end (i.e., the front and back faces) is a basic requirement. If the installation direction of the bearing is incorrect, it will not only lead to a decrease in pump efficiency, but also may cause serious mechanical failures such as overheating, accelerated wear, and even equipment damage. Traditional manual detection methods rely on the experience and skills of operators, which are highly subjective and prone to errors, making it difficult to meet the needs of large-scale production and high-precision detection.

[0004] With the development of automation technology, more and more enterprises have begun to adopt automated equipment to improve production efficiency and product quality. However, in the installation or detection production line of water pump bearings, achieving automatic judgment of the reference end of the bearing still faces certain challenges. Existing automation solutions often require complex vision systems and precise mechanical structures, which not only increase equipment costs but also make maintenance more difficult.
