At this time, it is necessary to separate TP film from glass cover plate, so as to reuse the glass cover plate.
[0003] In the conventional rework process, it is usually heated, cut off, remove glue and paste film. In the rework process, the OCA glue used for lamination needs to be heated and softened first, then the metal wire TP film and the OCA glue in the glass are cut off, the TP film is torn off from the glass, then alcohol and other chemical agents are used to clean the surface of the glass until the surface is free of glue and dust, and finally a new TP film is laminated. Since the size of TP film is large, it is necessary to cut off all the OCA glue and directly tear off the TP film from the glass cover plate, which not only needs a lot of force to repeatedly pull the metal wire to cut off the OCA glue, but also needs to resist the glass in the cutting process to prevent the glass from being damaged in the pulling process. In order to ensure that the OCA glue is cut off without damaging the surface of the cover plate glass, the cutting of OCA glue and the tearing of TP film are usually completed by manual operation, which is very laborious.
