US 2011/0095467 A1 · Adaptive Clamp Width Adjusting Device

Abstract

The present invention describes an adaptive clamp width adjusting device (200) for use in an integrated circuit package process machine. The device (200) includes a travel component (210) and a fixed component (310). The travel component (210) carries a clamp (220a,220b) with an adjustable width and a rotary screw (230a) operable for such adjustment by a driven wheel (232). The fixed component (310), mounted on a base plate (312), includes a motor (320) and a drive wheel (324) attacked to the motor shaft. When the device (200) is in a clamp width conversion station (40a), the travel component (210) is aligned above the fixed component (310) so that when the base plate (312) is raised and the drive wheel (324) engages the driven wheel (232), the clamp width is operable to be adjusted by the motor (320) according to a width of a workpiece (W).

Dependent claims

An adaptive clamp width adjusting or setting device comprising:

a travel component, which comprises a fixed clamp portion, an adjustable clamp portion and a rotary screw for adjusting a distance between the fixed and adjustable clamp portions, with the rotary screw being operable by a driven wheel attached thereto;
and
a fixed component, which comprises a base plate and a motor mounted on the base plate, with the motor shaft having a drive wheel attached thereto;
wherein, when the clamp width is to be adjusted to accommodate a workpiece, the travel component is moved into alignment over the fixed component and the base plate is raised so that the drive wheel engages with the driven wheel and the distance between the fixed and moveable clamp portions is operatively adjusted by controlling the motor according to a width of the workpiece.
