  • Publication number: 20240203764
    Abstract: A die-transfer tool includes a source frame stage, a target frame stage, a roller, and a driving mechanism. The source frame stage is configured to secure a first tape. The target frame stage is configured to secure a second tape, wherein the second tape has an adhesive surface facing the source frame stage when the second tape is mounted on the target frame stage. The roller is configured to move laterally over the non-adhesive surface of the second tape opposite the adhesive surface when a plurality of dies is between the first tape and the adhesive surface of the second tape. The driving mechanism is configured to vertically drive the target frame stage to adjust the relative position of the target frame stage above the source frame stage.

  • Patent number: 7704030
    Abstract: The present invention pertains to a screw for use in nonmetal objects comprising a plurality of cut-aiding portions formed by the longer and shorter cutting surfaces inclined toward opposite directions. Further, a cutting edge formed by the junction of any two adjacent cutting surfaces presents in a fastening direction of the screw. Thus, the cutting edge assists the threads to thoroughly severe and to shatter the fibers and debris of the objects, which can also be accommodated into the cut-aiding portions. Also, the ridge of the longer cutting surface aids in cutting fibers and further guides the debris out. In this manner, the present invention facilitates to enhance cutting capability for obtaining less screwing resistance, to prevent the destruction of the object and to increase the screwing speed.

  • Publication number: 20090110512
    Abstract: The present invention pertains to a higher fastening screw comprising a plurality of concavities formed on the threads, which are connected in sequence for being presented as a state of a single helix. Further, the concavities separately located adjacent to the screw head and to the drilling portion are disposed at relative positions for being accurately aligned by an imaginary line. In this manner, the configuration of the concavities would efficiently cut and sever the fibers of the object, so as to achieve a lower screwing resistance for a higher screwing efficiency and prevent the injuries to the operators.
