[0002] Wire harness processing refers to the process of processing and assembling various electrical cables, connectors, insulating sleeves and other raw materials through a series of processes such as stripping, cutting, crimping, and fixing to make electrical connection harnesses that meet specific requirements according to product design requirements. This process needs to be carried out strictly in accordance with the design drawings and process requirements to ensure that the quality of each wire harness is reliable and the performance is stable, so that it can be used in various electronic products and equipment to play its role in connecting and transmitting electrical signals.

[0003] In wire harness processing, a terminal crimping machine is needed to crimp the terminals. Although the existing technology has met the user's needs to a certain extent, there are still certain defects in the use process. The specific problems are as follows: when in use, the terminal crimping machine usually crimps one end of the wire harness and then crimps the other end of the wire harness. After the crimping on one side is completed, the wire harness on the other side may move or loosen, resulting in a loose connection, which in turn affects the quality and stability of the wire harness. Additional processes or manual operations are required to ensure the connection quality of the wire harness on the other side, which increases working time and cost, and is prone to inconsistencies, affecting overall production efficiency and product quality.
