[0002] In the production process of industries such as electronics, electrical appliances, and automotive wiring harnesses, terminal wire processing is a critical step. It requires the completion of processes such as wire stripping, terminal crimping, and waterproof plug assembly to ensure the electrical connection reliability and waterproof performance of the wiring harness. As the industry continues to increase its requirements for production efficiency and product quality stability, terminal wire processing equipment is gradually developing towards automation. Currently, some terminal wire processing equipment has significant shortcomings. In the waterproof plug processing stage, there is a lack of efficient screening, conveying, and precise alignment mechanisms, which often results in problems such as disordered arrangement of waterproof plugs and large deviations in connection with the wires, affecting assembly quality. Furthermore, the coordination between different processes of the equipment is poor. For example, the processes of stripping, crimping, and inserting waterproof plugs are not smoothly connected and require manual adjustment, which not only increases labor costs but also reduces overall production efficiency, making it difficult to meet the high-efficiency and precision requirements of large-volume terminal wire processing. To address this, we have proposed a fully automatic double-head terminal crimping and waterproof plug insertion terminal machine. Utility Model Content
