Assembly nut conveying device and control method

The invention discloses an assembly nut conveying device which comprises a protection module, a capturing module, a conveying module, a gas supply module and a system module, nuts enter from a sliding collection guide port, matched nuts are guided out from a gas supply guide port after model detection, by designing a strip-shaped supply structure, supply and demand space are separated, adaptive scenes are increased, and meanwhile multi-direction use is facilitated; carrying in assembly and installation operation is facilitated; a capturing module is designed to capture assembly nuts of various models, and the application range of the device is widened while specification matching inspection of the assembly nuts is achieved; a conveying module is designed, a multi-specification nut assembling operation mode with rotation and movement separated is formed, and efficient circulating operation of the device is achieved; the gas supply module for pushing and supplying the assembly nuts through gas is designed, and
