However, this method requires regular replacement of the tape, which reduces the productivity and increases the production cost.
The second method is to pick up the protective film with a needle and then to remove the protective film with a clip. As shown in fig. 4 and 5, one end of the protective film 13 is lifted up using a needle (pin)17, and then the protective film 13 is sandwiched upward using a clip 18 to be peeled off. However, this method easily causes the adhesive remaining on the pin to cause secondary contamination, and then the protective film is easily dropped in the process of clamping the clip.
Therefore, it is necessary to provide a film tearing device and a method for using the same to solve the problems of the prior art.

As shown in fig. 6 and 7, the film tearing device 20 of the present invention is used for peeling off the protective film 13 of the welding area, wherein the protective film 12 of the display area and the protective film 13 of the welding area are disposed on the flexible oled display panel 11, the film tearing device 20 includes a suction nozzle 21, an air duct 22, and a processing module 23, the suction nozzle 21 is disposed above the film 13 to be peeled, the suction nozzle 21 is connected to the processing module 23 through the air duct 22, and the processing module 23 is used for providing an adsorption force to the suction nozzle 21 through the air duct, so that the film 13 to be peeled is peeled off under the adsorption force of the suction nozzle 21, that is, the film 13 to be peeled off is peeled off from the welding area of the display panel.
Wherein, in order to improve the efficiency of the suction, the suction nozzle 21 has a suction surface 211, the suction surface 211 is close to the side of the film to be torn 13, and the area of the suction surface 211 is larger than that of the film to be torn 13. Preferably, in order to improve the absorption effect, the area of the absorption surface 211 is slightly larger than the area of the film to be torn 13, that is, the difference between the area of the absorption surface 211 and the area of the film to be torn 13 is within a preset range.
