  • Publication number: 20240131808
    Abstract: A tape laying device includes a tape transmission mechanism, a compaction head mechanism, a cutter mechanism, a heating mechanism and a motion mechanism. The tape transmission mechanism is configured to transmit the pre-impregnated tape. The compaction head mechanism, connected with the tape transmission mechanism, is configured to depress and drive the pre-impregnated tape transmitted by the tape transmission mechanism to follow a moving path so as to adhere the pre-impregnated tape onto the mould surface. The cutter mechanism is configured to cut the pre-impregnated tape. The heating mechanism, disposed downstream to the cutter mechanism, is configured to heat the pre-impregnated tape. The motion mechanism is used to have the cutter mechanism having an active path to move toward the moving path while the cutter mechanism cuts the pre-impregnated tape.
