The system comprised of a rivet bowl feeder, an escapement and a punch assembly. The bowl feeder fed rivets in the correct orientation to an escapement before presenting it to an upper punch, which retained the rivet through vacuum.
The punch assembly consisted of a “C” frame, pneumatic cylinder, upper and lower punch assembly and component clamping pin. The upper punch assembly uses a spring-loaded inner punch in a normally open position to allow a vacuum to be achieved in order to hold the rivet.
SP Automation & Robotics designed a unique rivet tooling comprising of the vacuum hold tool, locating tool, stripper tool, and lower tooling. To allow the system to cater for various lengths of rivets, and thicknesses of sheet metal material, interchangeable stops/collars were provided. This enabled the client to quickly change between batches and set-ups.
Digital signals were required to enable the future cobot to integrate with the system seamlessly.
