High temperature carrier film consists of three layers: carrier film layer, adhesive layer, and release film layer. Before use, the release film of the high temperature carrier film must be torn off, and then the adhesive side is attached to one side of the FPC PET substrate, and then the other side is used for the rest of the process.

When the position of the carrier film layer is offset, the film pasting position is inaccurate, which affects the film pasting quality of the equipment and reduces the film pasting efficiency of the equipment. After the edge of the carrier film layer is installed on the anti-sticking pad 805, the electric adjustment rod 802 starts to operate, and the pressing plate 804 is pressed down to fix the carrier film layer, thereby increasing the stability of the equipment, ensuring the accuracy of the equipment during film pasting, and improving the film pasting quality of the equipment. After the fixation is completed, the electric telescopic rod 10 starts to press down, and the laminator 11 presses the carrier film layer onto the film pasting original 15 for film pasting. During the film pressing process, the film breaking blade on the outer frame of the sliding frame 16 is used to automatically cut the carrier film. The film-applied original 15 is transported out through the electric push rod 13, the staff replaces the film-applied original 15, the electric push rod 13 is restored, the electric motor 706 starts to operate and drives the rotating column 702 to rotate and rewind the residual pieces of the supporting film layer that has just been film-applied, and pulls the supporting film layer out for film-applied work, the power gear 705 drives the linkage gear 709 to rotate through the linkage belt 707, and automatically removes the release film.
