In traditional manual assembly, workers need to complete multiple steps such as wire cutting, stripping, terminal crimping and insertion, which is not only inefficient, but also prone to poor product consistency and high scrap rate due to operational errors. At the same time, manual operation requires high skills of workers, and long-term operation can easily cause fatigue and work injuries. In addition, with the popularization of electronic devices and intelligent applications, the market demand for wire terminals continues to increase, and manual operations are difficult to meet the production needs of high efficiency and high quality.

[0003] In order to solve these problems, automatic assembly machines for wire terminals have been gradually applied to the production field. Its automated assembly method integrates cutting, stripping, terminal crimping, detection and other functions to achieve efficient continuous production, greatly improving efficiency and consistency. However, the current automatic assembly technology still has some shortcomings, such as: complex equipment structure, high development and maintenance costs; low compatibility with specific specifications or non-standard terminals; under high precision requirements, equipment stability and reliability still need to be optimized.
