  • Servo motor tension control for modular AFP head assembly
    Patent number: 10981342
    Abstract: A modular head assembly or end effector for a fiber placement machine having a machine controller includes a back plate and a plurality of carbon fabric spool assemblies, each assembly including a servo motor combination and a dancer assembly for maintaining tension of the fabric as it is payed out. The spool assemblies include a linear displacement sensor for the dancer assembly and a sensor for determining the diameter of the carbon spool, the outputs of which are used to control the action of the servo motors. A programmable disconnecting assembly mates the modular head assembly with the fiber placement machine.
