[0046] The film laminating process using the film laminating machine 100 of the present application is as follows:

[0047] Start, the vacuum pump 131 is energized, the upper solenoid valve 132 is energized, the upper cavity 1111 is connected, and the upper cavity 1111 is evacuated. The pressure relief solenoid valve 134 is not energized and is in a closed state. The pressing film 120 is elastic and moves upward elastically. About 2 seconds later, the lower solenoid valve 133 is energized, the lower cavity 1112 is connected, and the lower cavity 1112 is evacuated. At this time, the upper and lower cavities 1112 are evacuated at the same time.

[0048] When the pressure is evacuated to about -100KPA, the air in the cavity is extremely rarefied, the upper solenoid valve 132 is powered off, and the upper cavity 1111 is stopped from being vacuumed. The upper solenoid valve 132 is powered off for about 5 to 10 seconds, and the pressure relief solenoid valve 134 is powered on, and the upper cavity 1111 is connected to the atmosphere through the pressure relief solenoid valve 134, and the pressure of the upper cavity 1111 is relieved. At this time, the pressing film 120 is under the pressure of atmospheric pressure, and the pressing film 120 moves downward to press the mobile phone UV film downward until the mobile phone UV film is pressed against the mobile phone. At this time, the lower cavity 1112 is about -100kpa, and the air is extremely rarefied, and no bubbles will be generated between the mobile phone UV film and the mobile phone.

[0049] The pressure relief solenoid valve 134 is energized for about 10-20 seconds, and the mobile phone UV film is well attached to the mobile phone. The pressure relief solenoid valve 134 is de-energized, closing the connection between the upper cavity 1111 and the atmosphere. The upper solenoid valve 132 is energized, and the upper cavity 1111 and the lower cavity 1112 are simultaneously evacuated for 10 seconds. The lower solenoid valve 133 is de-energized, and the lower cavity 1112 is connected to the atmosphere through the lower solenoid valve 133 to relieve pressure. After 2 seconds, the upper solenoid valve 132 is de-energized, the film pressing sheet 120 is separated from the mobile phone and the mobile phone UV film, the film pressing sheet 120 is reset, and the mobile phone UV film is attached to the mobile phone.

[0050] The upper electromagnetic valve 132 is energized, connected to the upper cavity 1111, and the upper cavity 1111 is evacuated. The membrane sheet 120 is elastic, and the membrane sheet 120 elastically moves upward. About 2 seconds later, the lower electromagnetic valve 133 is energized, connected to the lower cavity 1112, and the lower cavity 1112 is evacuated. At this time, the upper cavity 1111 and the lower cavity 1112 are evacuated at the same time.

[0051] When the vacuum is evacuated to about -85KPA, the upper solenoid valve 132 is powered off, and the upper cavity 1111 is stopped from being evacuated. The upper solenoid valve 132 is powered off for about 5 to 10 seconds, and the pressure relief solenoid valve 134 is powered on, and the upper cavity 1111 is connected to the atmosphere through the pressure relief solenoid valve 134, and the pressure of the upper cavity 1111 is relieved. At this time, the pressing film 120 moves down under the pressure of atmospheric pressure, and the UV film of the mobile phone is pressed down until the mobile phone film is pressed against the mobile phone. At this time, the pressure of the silicone sheet on the mobile phone film is smaller than that at -100kpa, and no white edge will appear after UV curing. Turn on the UV lamp, and the UV light passes through the transparent pressing film 120 to cure the UV film of the mobile phone. When the UV curing time is up, the pressure relief solenoid valve 134 is powered off, and the upper solenoid valve 132 is powered on. At this time, the upper cavity 1111 and the lower cavity 1112 are evacuated at the same time for about 10 seconds. The lower solenoid valve 133 is powered off, the lower chamber 1112 is depressurized, and after 2 seconds, the upper solenoid valve 132 is powered off, the film pressing sheet 120 moves upward, and the vacuum pump 131 is powered off. The film is applied, the applied mobile phone is taken out, and the release film is torn off.
