[0018] The three-prong terminal riveting mechanism of this embodiment can realize the automatic riveting of three-prong terminals. The stamping assembly is equipped with a sensor 311, which can sense whether there is a terminal at the stamping position, which helps to improve the operational stability and efficiency of the three-prong terminal riveting mechanism. Specifically, the three core wires of the wire enter through the wire inlet assembly. The three core wires pass through the three-core wire inlet respectively. The wire inlet assembly guides the core wires. Then the terminal conveying assembly conveys the terminal forward. The sensor 311 senses that the terminal has been conveyed to the predetermined position. The stamping assembly performs the stamping operation to rivet the three-prong terminal to the core wire. Then the wire inlet die cylinder drives the wire inlet module group to separate. The riveted power line with the terminal leaves the three-prong terminal riveting mechanism.
