Description

Technical Field

[0001] The invention belongs to connector automatic processing technology, and in particular relates to a heterosexual terminal pin mechanism. Background Art

[0002] The main function of the connector is to transmit electrical signals from one circuit system to another through terminals. Connector terminals are the general term for connector hardware, including shells and terminals. During their production process, pin insertion operation is required, that is, the terminals are inserted into the carrier.

[0003] The traditional mechanical cam pin insertion mechanism includes a cam box and an XYZ three-axis robot module to complete the automatic pin insertion of the terminal. The traditional mechanical cam is a five-piece cam mechanism, namely the lower head cam, the upper chuck cam, the upper knife cam, the lower knife cam, and the pin insertion cam. The upper and lower knife cams are used to cut the terminals from the material strip, and the upper and lower chuck cams hold the cut terminals. The automatic pin insertion of the terminals is achieved through the cooperation of the pin insertion cam and the XYZ three-axis robot module.

[0004] Traditional pin insertion mechanisms are unable to insert non-straight terminals, nor can they insert two types of terminals on a single strip. Because the pin insertion platform is fixed, it cannot accommodate angled terminals. The position of the pins cannot be adjusted for angled terminals, making insertion angle and depth impossible. According to traditional designs, current pin insertion mechanisms struggle to accommodate heterogeneous and angled terminals. They also suffer from complex structures, numerous procedures, high failure rates, and low insertion precision. Summary of the Invention
