Abstract
A TAB-type lead automatic inspection system is provided to position with high accuracy at high speed for improving reliability and productivity of inspecting. A lead positioning method used for a TAB-type lead automatic inspection system or processing system, comprising fixing a product onto a table movable in an X-axis direction and two Y-axis directions in parallel to the product mounting surface, and positioning X-axis, Y-axis and rotational angle .theta. directions, and a lead positioning device used for a TAB-type lead automatic inspection system in a highly rigid translation mechanism provided with a pair of hinges in one sheet plate comprising microfeeding piezoelectric actuators for driving a translation mechanism of one axis in the X-axis direction and two axes in the Y-axis direction, and control means for feedbacking a lead positioning sensing signal, and driving each piezoelectric actuator, thereby positioning X, Y and .theta. directions with high accuracy at high speed.
