Description

Technical Field

[0001] The present invention relates to the technical field of stamping production lines, and particularly relates to a high-speed servo terminal feeding stamping production line and its production process. Background Art

[0002] In the field of traditional terminal manufacturing, there are generally problems such as low production efficiency and complex processes in the feeding stamping production line. Especially in the processing of multi-component terminals, the single-tape stamping mode is difficult to meet the requirements of high-efficiency production.

[0003] Existing production lines mostly adopt the single-tape step-by-step processing mode, where different components need to be stamped separately and then assembled. For example, for the flat plug terminals of new energy vehicles, the metal outer sleeve and the contact piece need to be processed independently first, and then completed through processes such as riveting and bending. This leads to repeated investment in equipment and loss in process connection, low production and assembly efficiency, easy material interference during double-tape synchronous feeding, and lack of a collaborative positioning mechanism, resulting in cumulative alignment errors and a high rejection rate. Moreover, the existing terminal stamping production line is not equipped with a vision inspection system, resulting in product defect identification relying on manual visual inspection or simple mechanical inspection, with problems such as low inspection efficiency, high missed inspection rate, and poor real-time performance.
