  • Patent number: 11007728
    Abstract: This invention relates to a fiber placement head integrating tow converging mechanism, comprising: fiber placement head mounting base; fixed yarn box component and revolving yarn box component arranged at the side end of the fiber placement head mounting base, tow passage formed between the revolving mounting face of the said fiber placement head mounting base and the relative face of the revolving yarn box component; tow conveying components respectively arranged on the sides of the fixed yarn box component and revolving yarn box component; and tow converging mechanism for guiding and converging tows conveyed by tow conveying components. Through appropriate design of guide pulley and tow passage, the fiber placement head realizes the guiding and converging of multiple tows, avoiding intervening among the tows.

  • Patent number: 10632693
    Abstract: A fiber coil mounting device is used in automated composite material layup equipment. The fiber coil mounting device includes a fiber coil mounting shaft with axial hollow structure, a fiber stop plate disposed on two sides of the fiber coil mounting shaft, and an anti-slide fiber coil tightening mechanism. The anti-slide fiber coil tightening mechanism includes a piston assembly disposed inside the axial hollow structure, a spring piece disposed on the piston assembly, a driving unit controlling an axial slide of the piston assembly, and a tightening unit driven by an axial force produced by the spring piece during the axial slide of the piston assembly.
