At present, liquid crystal displays are used as display panels in various portable electronic products, and particularly, liquid crystal displays are important components of products such as video cameras, notebook computers, mobile terminals, personal digital processors, and the like. In addition to the liquid crystal panel, the liquid crystal display panel must be connected with a driving chip at its periphery for controlling the display signal, and in order to realize the conduction of the chip, an ACF (anisotropic conductive film) needs to be laminated on the Flexible Printed Circuit (FPC).
The existing ACF conductive adhesive film attachment modes include two modes, namely a pressure head attachment mode and a roller attachment mode. Wherein, the pressure head attaching mode is as follows: pressing the ACF adhesive tape on the display substrate through a pressing head for about 0.5-1S generally, then lifting the pressing head, and finally peeling off the base band of the ACF adhesive tape attached to the display substrate through a peeling rod to leave only the ACF conductive adhesive film; the roller attaching mode is as follows: the ACF adhesive tape is pressed on the display substrate from right to left by controlling a roller through a cylinder, then the roller is lifted up by the cylinder, and finally the peeling rod is controlled by another cylinder to move from right to left, so that the ACF base band is separated from the ACF conductive adhesive film.
