In the embodiments provided in the present disclosure, the blowing device 200 may be disposed above the inside of the cavity 100, and may also be disposed above the outside of the cavity 100. According to some embodiments, referring to fig. 6 and 7, the blowing device 200 is disposed outside the cavity 100, for example, outside the second cylinder 140 described above. Wherein, the roof of cavity 100 can be seted up a plurality of gas inlets 101 that the gas got into cavity 100 inside, and a plurality of gas inlets 101 can evenly be laid on the roof, all provide gas pressure for each position of protection film 30 upper surface.

Further, as shown in fig. 6 and 7, the blowing device 200 may be configured as a first groove structure matching the shape of the top of the chamber 100, and the notch of the first groove structure faces the air inlet hole 101, so that the blowing device 200 and the top of the chamber 100 enclose a closed structure, further concentrating the air in the chamber 100. According to some embodiments, the blowing device 200 may further be opened with an air inlet for the external air to enter, so as to blow the external air to the inside of the cavity 100.

Referring to fig. 2 to 4, the film pasting device provided by the present disclosure may further include a vacuum suction device 300 installed below the cavity 100, for example, the vacuum suction device 300 may be installed below the first cylinder 130, so as to suck the gas at the bottom of the cavity 100, so that a certain pressure difference is formed between the top and the bottom of the cavity 100, which is more beneficial for pasting the protection film 30.

Further, the vacuum suction device 300 may be disposed below the inside of the chamber 100, or may be disposed below the outside of the chamber 100. According to some embodiments, referring to fig. 2 to 4, the vacuum suction device 300 may be disposed outside the chamber 100, for example, outside the first cylinder 130 described above. A plurality of exhaust holes 102 for discharging gas can be formed in the bottom wall of the cavity 100, and the exhaust holes 102 can be uniformly distributed on the bottom wall, so that negative pressure can be formed at each position of the lower surface of the protective film 30.

According to an embodiment provided by the present disclosure, referring to fig. 4, 6, and 7, the protective film 30 may cover the entire opening surface of the first cylinder 130. Thus, after the second cylinder 140 is fastened to the first cylinder 130, the protection film 30 can separate the interior of the cavity 100 into two relatively closed chambers, the blowing device 200 works to gradually increase the gas pressure in the chamber where the second cylinder 140 is located, the vacuum absorbing device 300 works to gradually decrease the gas pressure in the chamber where the first cylinder 130 is located, and the gas pressure difference between the two chambers gradually increases, so that the gas pressure applied to the protection film 30 can be further increased, the protection film 30 is firmly pressed on the device 20 to be attached, and the attachment of the protection film 30 is facilitated.

It can be seen that the sticking of the protective film 30 to the screen of the apparatus 20 to be film-attached can be achieved by the single action of the air blowing means 200 or the combined action of the air blowing means 200 and the vacuum sucking means 300. In the embodiment where the protective film 30 is a tempered film and the blowing device 200 has a heating component, the device to be laminated 20 may further have a 3D curved screen, for example, the device to be laminated 20 may be a full-screen mobile phone having a 3D screen. Adopt the pad pasting device that this disclosure provided can carry out the pad pasting to the 3D screen fast effectively, and each position homoenergetic that protection film 30 corresponds to the curved surface screen can receive balanced gas pressure for one-step pad pasting of curved surface screen targets in place, and can not produce bubble or fold. After the film pasting is completed, a CCD positioning system can be adopted, and laser fine cutting is used for cutting off the redundant protective film 30 along the periphery of the screen, so that the film coating process of the protective film 30 is finally completed.
