  • Publication number: 20070217897
    Abstract: The present invention relates to a multi-directional gripping apparatus, adapted for fetching and positioning workpieces, which is primary comprised of a grabber and a driving mechanism. The grabber is further comprised of a rotation shaft and a plurality of gripping arms; wherein the plural gripping arms are positioned centering around the rotation shaft while extending toward different directions in respective. The driving mechanism includes a vertical driver, a horizontal driver and a rotation driver, by which the grabber can be driven to rotate and perform a vertical movement and a linear horizontal movement. By orientating the plural gripping arms to extend toward different directions in respective, more than one workpieces can be fetched and positioned to be processed simultaneously, such that the operation efficiency of the mechanical platform as well as the gripping apparatus are optimized, thereby the manufacturing process is shortened and the throughput is increased.

  • Patent number: 6984998
    Abstract: A multi-function probe card (40) includes a PCB (41), a plurality of probe needles (47), a counter (71) to acquire a “piece sequence parameter”, a signal-measuring device (72) via the probe needles (71) to acquire a current, and a voltage parameters etc. as well as a parametric processing system (74). The parametric processing system (74) includes an I/O unit (51)/(59), a processing unit (52), a time providing unit (55), a real time display unit (56), and a storing unit (57). Moreover, the piece sequence parameter, current parameter, and voltage parameter can be input into the processing unit (52) through the I/O unit (51)/(59). Thereafter, a parametric data structure can be set up to record and calculate in accordance with the datum and parameters, and finally to display service processes and conditions of the probe card (40) through the real time display unit (56).
