1. A multi-degree-of-freedom additive mixed weaving apparatus for a continuous fiber reinforced composite material, comprising a printing platform, a robotic arm, an additive device, and a fiber pulling device, wherein:
a lower surface of the printing platform is provided with a displacement device, and the displacement device is used to rotate the printing platform horizontally and adjust a pitch angle of the printing platform,
the additive device is located above the printing platform and is connected to one end of the robotic arm, and the additive device is provided with a pressing roller, the pressing roller attached to the additive device with a support rod,
the robotic arm comprises a plurality of rotating joints used to drive the additive device to print and melt a fiber tow on the printing platform according to a predetermined path,
the fiber pulling device is disposed on the printing platform and is used to grab a pre-set vertical reinforced fiber and make it cross-weave with the fiber tow in each layer of printing, and
when working, the robotic arm drives the additive device to print, and the displacement device drives the printing platform to move with the additive device, so that a central axis of the support rod of the pressing roller is always perpendicular to a horizontal plane defined by the lower surface of the printing platform to press the melted fiber tow and the reinforced fiber cross-woven with the fiber tow,
wherein the additive device comprises a fixed platform, an upper surface of the fixed platform is connected to one end of the robotic arm, and a lower surface of the fixed platform is provided with a tow feeding mechanism and a laser, and wherein the tow feeding mechanism is used to output the fiber tow onto the printing platform, and the laser is used to melt the fiber tow.
