Referring to FIG. 1 , the template 210 can also move the protective film 20 fixed on the template 210 to the side of the electronic device 30 where the surface 31 to be filmed is located, so that the protective film 20 is spaced from the surface 31 to be attached. In one embodiment, the protective film 20 can be directly opposite to the surface 31 to be attached to the film, that is, both the outer surface and the inner surface of the main body portion 21 are opposite and parallel to the main body surface 31a. Of course, the protective film 20 can also be inclined relative to the surface 31 to be attached to the film, that is, both the outer surface and the inner surface of the main body portion 21 are inclined relative to the main body surface 31a.

The clamping assembly 220 includes a first clamping member 221 and a second clamping member 222 . The protective film 20 has a first end 20a and a second end 20b disposed opposite to each other, and the first end 20a and the second end 20b can be understood as two ends of the protective film 20 in the length direction. The first clamping member 221 and the second clamping member 222 are used to clamp the opposite sides of the first end 20a of the protective film 20 fixed on the template 210, so that the side portion 22 located at the first end 20a can be unfolded. (The side portion 22 located at the expanded first end 20a can be flush with the main body portion 21, and can also be close to flush). Wherein, the first clamping member 221 and the second clamping member 222 may be coated with an anti-scratch film to reduce the risk of offset printing of the protective film, and the anti-scratch film may be an AF film.

In one embodiment, the first clamping member 221 is movably disposed on the template 210 and can hold the outer surface of the protective film 20 (it can be understood that the first clamping member 221 moves along the Z-axis direction shown in FIG.

In this way, the side portion 22 located at the first end 20a that is flush with the main body portion 21 can continue to maintain the flush state under the load-bearing action of the first bracket 311 and the second bracket 312 to avoid rebounding. In other embodiments, the first bracket 311 and the second bracket 312 can be omitted. In this case, the template 210 can first release the second end 20b of the protective film 20 so that the second end 20b overlaps the surface 31 to be attached to the film, and the second end 20b One end 20a is still held by the holding assembly 220 .

In step S850, the film sticking member 320 is moved from the second end 20b of the protective film 20 toward the first end 20a, so that the main body portion 21 of the protective film 20 is attached to the main body surface 31a, and the side portion 22 of the protective film 20 is attached to the main body surface 31a. Fitted with the side peripheral surface 31b. In one embodiment, the film sticking member 320 includes a roller, so that the roller rolls along the surface 31 to be filmed from the second end 20b of the protective film 20 toward the first end 20a. Wherein, in the embodiment of the first bracket 311 and the second bracket 312, when the film sticking member 320 moves to the first end 20a, the first bracket 311 and the second bracket 312 are removed, so that the first end 20a is attached to the Surface 31 to be filmed. In the embodiment in which the first bracket 311 and the second bracket 312 are omitted, when the film sticking member 320 moves to the first end 20a, the second clamping member 220 is removed, and the first end 20a of the protective film 20 is released, so that the first end 20a of the protective film 20 is released. One end 20a is attached to the surface 31 to be filmed.

In the film sticking method of the present application, since the first clamping member 221 and the second clamping member 222 are configured to be able to clamp the opposite sides of the first end 20a of the protective film 20, the first end 20a is located on the side of the first end 20a. The part 22 can be unfolded, so that when the film sticking member 320 moves from the second end 20b toward one end to press the protective film 20 to fit the surface 31 to be filmed, the gas between the protective film 20 and the surface 31 to be filmed can be trapped in the film sticking piece Under the compressive action of the 320, the gas diffuses from the second end 20b toward the first end 20a and is discharged from the position where the side portion 22 after the first end 20a is unfolded, avoiding the accumulation of gas in the side portion 22. The risk of gas is eliminated, so that the side portion 22 can better fit with the side peripheral surface 31b of the surface 31 to be filmed, the loss of the protective film 20 is reduced, the filming efficiency is improved, and automatic filming is realized.
