Description

Substrate positioning mechanism

The present invention relates to a substrate positioning mechanism, and more particularly to a substrate positioning mechanism for pre-positioning a substrate before the substrate is attached with an AAC (Anisotropic Conductive Film).

Generally, the electronic component and the circuit board may be connected by an anisotropic conductive film (ACF), which is applied to, for example, a flexible printed circuit (FPC), an IC. On a transparent electrode of indium tin oxide (ITO) on a glass substrate of a wafer terminal or a liquid crystal display (LCD) to form an electrical connection between the two terminal interfaces.

Substrate 10 The surface of the transparent electrode terminal (not shown).

However, since each of the positioning flaps 14 is locked and fixed by two screws 15 and each of the positioning flaps 14 has two long slots, the positioning flap 14 is relatively easy to rotate and faces the X direction during the locking process. The Y direction and the Y direction are respectively shifted to different degrees, and the offset degrees of the two positioning blocks 14 are also different from each other, so that it is not easy to be fixed at the correct locking position, which causes the substrate 10 to be positioned when positioning. The front side edge of the blocking piece 14 cannot be in flat contact with the other side surface 102 of the substrate 10, thereby causing a deviation in the angular positioning of the substrate 10 in the Y direction; further, each positioning blocking piece 14 is a leading edge (rectangular shape) The side surface) contacts the other side surface 102 of the substrate 10 via a surface contact manner, and the large area contact of the two is also easily worn, thereby causing loss of the other side surface 102 of the substrate 10.
