  • Patent number: 12186970
    Abstract: A multi-arm forming device for space on-orbit composite braiding is provided. Through the rotary movement of a combination of circularly arranged mechanical arm-type laying apparatuses relative to a mold, a plurality of hot press laying heads are controlled together to implement high-efficiency and high-freedom winding and braiding formation of a composite member. The retraction and expansion deformation of the gasbag mold is achieved by inflating and deflating based on design, and the overall device is lightened by switching its structural volume in an operating/non-operating state, thereby achieving the purpose of facilitating the lift-off of rockets and the demolding, repair and weight reduction of winding and braiding structural members for operation in space. Additionally, gas in a gasbag can be used as emergency kinetic energy for the movement and attitude adjustment of the overall device in space. High-quality and efficient winding and braiding formation of composites in space are achieved ultimately.

  • Publication number: 20240227287
    Abstract: A nozzle-replaceable printing head for continuous fiber printing and a printing method are provided. The printing head includes a fixed bracket, a wire feeding module located at an upper part of the structure, an upper guide pipe, a shearing module located at a middle part of the structure, a lower guide pipe, a heat dissipation sleeve, a throat pipe, a heating coil, and a nozzle module located at a bottom of the structure, where a continuous fiber reinforced thermoplastic resin matrix pre-impregnated composite wire coaxially penetrates through the other side of the printing head from top to bottom and is fed for printing. An adjustment groove with scales is configured to standardize adjustment on clamping and feeding states of pre-impregnated composite wires of different specifications.

  • Publication number: 20240227307
    Abstract: A path planning method based on dynamic contour offset discretization and for spatial curved-surface printing is provided. Firstly, transversal equal slicing is carried out on a target model, and single/double contours are labeled; secondly, central slicing is carried out on the model, curvature contours are discretized, feature values of contour offsets of slice layers are calculated on the basis of a surface contour curvature of the model, and dynamic offset filling for inner contours of horizontal slices is realized; then longitudinal equal slicing is carried out on the slices, and spatial discrete points of the target model are obtained; and finally, virtual double contours are constructed for the single contours, and labeling processing for the discrete points is carried out, so that a discretized three-dimensional spatial equidistant lattice of the target model is obtained.
