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.

Abstract: This invention relates to a cutter device for automated composite material placement equipment, including cutter component, drive mechanism that drives the cutter component to slide, and guide mechanism that provides slide room for the cutter component, the said guide mechanism comprises: cutter stop, base, cover plate arranged on the base, and cutting board arranged between the base and the cover plate; guide groove for accommodating cutter component slide is provided at the said base's contact side with the cutting board; the said cutter stop is arranged at the outer side of the guide groove to limit the cutter component from sliding out; the said cutting board has a protruding part relative to the base and the cover plate, a first tow guide hole is provided on the said protruding part; a second tow guide hole coaxial with the first guide hole is provided at the said cutter stop, a cutter avoidance groove is further provided at the said cutter stop's side close to the cutting board, and the second tow guide

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.

Abstract: This invention relates to a creel structure integrated on the fiber placement head of the automated placement equipment, comprising: fiber placement head mounting base, fixed yarn box component fixed and mounted on fiber placement head mounting base, and revolving yarn box component mounted on fiber placement head mounting base, the said revolving yarn box component is coupled with the fiber placement head mounting base through revolving shaft. This creel structure can avoid intervention that arise due to equipment maintenance and spindle replacement, making equipment maintenance and spindle replacement more convenient and swift.
