[0002] The sealing ring is a sealing component widely used in industrial fields, with good sealing performance and durability.

[0003] The main molding processes for sealing rings are calendering, compression molding and injection molding. In these commonly used sealing ring molding methods, excess soft glue will appear around the sealing ring during molding. Please refer to Figure 5 Excess soft glue 101 and 102 are formed on the outside and inside of the sealing ring 100. These soft glues have different shapes and need to be removed one by one. However, when the sealing ring is mass-produced, some excess soft glue will still be mixed in the sealing ring products.

[0004] According to Chinese patent CN213762921U, a sealing ring processing and sorting device is disclosed. The device detects the sealing ring through a weight sensor, and the weight sensor transmits the weight of the sealing ring to a motor. When the weight of the sealing ring meets the current starting requirement of the motor, the motor drives the sealing ring to be scraped into a collection box. However, this device cannot meet the needs of large-scale screening of sealing rings, and its sorting efficiency is low.
