Abstract

The application discloses a modular robot with a high-precision force control servo rivet gun and a control method thereof. The application can monitor the pre-tightening force and the breaking force of each rivet that needs to be riveted, so as to achieve intelligent control, automatic compensation, precise force control, real-time whole-process monitoring and rapid riveting functions. That is, the force condition and the monitoring process of riveting are monitored from the process of grabbing the rivet to the process of rivet entering the hole to the process of breaking the rivet, so that the riveting quality and the production standard are greatly improved. Through the high-precision force sensor and the control system, the application can accurately control the force in the riveting operation and automatically adjust the compensation force value. Through the servo motor and the high-precision transmission system, the application can accurately control the position of the rivet gun, so as to realize high-precision riveting operation. Through the preset riveting process parameters and the control system, the application can realize automatic and intelligent riveting operation.
