ABSTRACT:
A device for assembly of an STN liquid crystal module has a Y axis variable rail which is disposed at a crossing direction to an X axis rail and can ride on and slide down the X axis rail installed on the upper side of a table. A Y axis fixed rail is disposed opposite and parallel to the Y axis variable rail. A plurality of lug mounts are slidably disposed on the two Y axis rails. Vacuum pads are positioned at the outside of the two Y axis rails and parallel to each other and move toward or retract from the rails. The pads are at a height corresponding to the height of the upper side of the lug mount plus the thickness of the electromagnetic circuit element and the pads are supported and moved by a first double-acting cylinder. A pair of bars are disposed at a lower position than that of the vacuum pads and move toward or retract from the Y axis rails by using a second double-acting cylinder. A plurality of bending elements are slidably disposed on each bar. The bending element move with the bar and can pass adjacent the side of the grooves formed on the lug mount.
