  • Patent number: 4604027
    Abstract: Apparatus (11), which includes two adjacent wafer treating facilities (21 and 22), features an overhead positioning mechanism (20), the operation of which is controlled by a control module (48) to handle articles, such as semiconductor wafers (16), in a plurality of sequential plating operations. The vertical movement of a manipulator extension (46) is controlled with a relatively greater degree of precision to protect the wafers from becoming damaged. In the horizontal direction, a traveling frame (106) steadies a lead screw (59) spanning an extended distance between the two facilities (21 and 22) to support a precise movement of the manipulator extension (46) with respect to both of the facilities.

  • Patent number: 4425074
    Abstract: Articles (18) are transferred from a first position, such as a feed track (37) on which they are located closely spaced, to a second position such as a heat seal apparatus. At the heat seal apparatus the spacing of the articles is to coincide with the spacing of frame members (32) to which the articles are to be joined. The change in the spacing occurs during the transfer of the articles from the first to the second positions by means of a transfer mechanism (41). A plurality of pickup members (43) are slideably mounted to an arm (44) of the mechanism (41). The pickup members (42) which are resiliently urged apart with respect to each other are forced together at one end of the travel of the arm (44) to assume the close spacing established by the width of the pickup members. At the other end of the travel of the arm (44) the resilient urging force drives the pickup members (43) against predetermined stop positions.
