[0032] A sliding film applicator, such as Figures 1-6As shown, it is composed of a frame 1, positioning posts 110, slide rails 120 and a slider 2. The frame 1 is provided with a receiving cavity 130. The receiving cavity 130 is provided with a limiting portion 131. The positioning posts 110 are arranged on two opposite sides 101, 103 of the frame 1. The slide rails 120 are arranged on the other two sides 102, 104 of the frame 1 where no positioning posts are provided. The slider 2 can slide on the slide rails 120. The bottom of the slider 2 is provided with rollers 201. The rollers 201 are provided with a roller shaft 202 perpendicular to the slide rails 120. It is characterized in that: one end of the slide rail 120 is bent and extended to the side 105 of the frame, so that the slider 2 can slide to the side 105 of the frame and be flipped from horizontal sliding to vertical sliding. The receiving cavity 130 is used to receive the electronic product to be film-applied. The limiting portion 131 is used to fix the electronic product to be film-applied, generally in a U shape, and an inverted eight shape is also acceptable. The material can be made of foam material and adhered to the receiving cavity. By equipping U-shaped foams of different sizes, different sizes of products to be film-applied can be adapted, which can reduce the manufacturing of the film-applying device mold and save production costs. The positioning posts 110 are for cooperating with the screen protector with positioning holes. The positioning posts 110 are arranged on two opposite sides 101, 103 of the frame 1, mainly to support the screen protector on both sides and keep the screen protector as horizontal as possible. The slide rails 120 are arranged on the other two sides 102, 104 of the frame where no positioning posts are provided so that the slider 2 can slide above the screen protector without being interfered by the positioning posts 110. When the slider 2 slides, the pressure is transmitted to the screen protector through the rollers 201, so that the screen protector is close to the screen to complete the film application. The material of the rollers 201 has elasticity, such as rubber. The shape of the rollers 201 is adapted to the screen, that is, if the screen is flat, the rollers 201 are cylindrical; if the screen is a double-sided curved screen, the shape of the rollers 201 is adapted to the curved screen. In order to make the rollers apply pressure to the screen protector, at the same horizontal plane, the lowest height of the rollers 201 must be lower than the height of the positioning posts 110. Therefore, one end of the slide rail 120 is bent and extended to the side 105 of the frame, so that the slider 2 can slide to the side 105 of the frame and be flipped from horizontal sliding to vertical sliding. When the slider 2 is flipped, it will drive the rollers 201 to avoid the positioning posts 110 and not collide with the positioning posts 110 relatively close to the side 101 where the slide rail is fully extended.

[0033] Preferably, as Figures 3-5As shown, the width H of the slider 2 is less than the height L of the entire sliding film applicator when the slider 2 is in the horizontal sliding state, and / or both ends of the slide rail 120 are provided with stoppers 121, and a concave portion 203 is provided on one side 101 close to the horizontal plane when the slider 2 slides vertically. When the slider 2 is flipped to the side 105, the width H of the slider 2 is less than the height L of the entire film applicator when the slider is in the horizontal sliding state. At this time, the overall height of the sliding film applicator is significantly reduced compared to L when the slider is in the horizontal sliding state, which is beneficial for reducing packaging during product factory shipment, facilitating transportation, and at the same time reducing packaging costs. Both ends of the slide rail 2 are provided with stoppers 121, so that the slider 2 moves within the slide rail and does not completely slide out. The concave portion 203 facilitates the user to hold and slide the slider, and when the slider 2 is in the vertical sliding state, the user's fingers do not touch the tabletop and the slider can be lifted again.

[0034] Preferably, as Figure 1 、 2 、4 - 6 show, the slide rail 120 is a groove, and both ends of the slider 2 are provided with sliding shafts 204 that match the groove. The slider 2 slides within the groove 120 relying on the sliding shafts 204.

[0035] Preferably, as Figures 4-6 shown, the number of positioning posts 110 provided on one side 101 of the frame 1 relatively close to the side where the curved extended slide rail is provided with positioning posts is two, and a support portion 140 is further provided between the two positioning posts 110. The number of positioning posts 110 on the same side is two in order to better stretch the screen protector. Similarly, the function of the support portion 140 is to support the screen protector from bottom to top, prevent the user from accidentally touching it, keep the distance between the screen protector and the screen of the product to be film-applied when the slider 2 has not slid, not to be immediately attached, facilitate dust removal, and make it fit more evenly when the slider 2 slides.

[0036] Preferably, as Figure 1 、 2 、4, 6 show, the two sides 102, 104 of the frame 1 provided with the slide rail are further provided with first limiting strips 150. The length of the first limiting strips 150 is shorter than that of the slide rail 120, and they are parallel to the slide rail 120 in space. Both ends of the slider 2 are provided with first limiting grooves 250 that match the first limiting strips. Since the sliding shafts 204 and the slide rail 120 are on the same horizontal plane, and the additional first limiting strips 150 and first limiting grooves 250 are on the same vertical plane, it is more beneficial for the slider 2 to slide in a fixed direction in space.

[0037] Preferably, as Figure 2 、 6As shown, positioning strips 205 are provided at both ends of the slider 2. The sliding shaft 204 is arranged on the positioning strips 205. The positioning strips 205 are matched with the grooves 120 and can slide on the grooves 120. The sliding shaft 204 is a protruding cylinder. There are two sliding rails 120. When the sliding shaft 204 slides, it is not easy to keep both ends sliding in parallel. However, for the positioning strips 205, since they are strips and the sliding shaft 204 and the positioning strips 205 are on the same horizontal plane, it can keep the sliding more parallel and uniform without shaking up and down.

[0038] Preferably, as Figure 1 、 4 、6 shows, the sliding rail 120 is provided with a notch 122, so that when a part of the positioning strip 205 slides out of the sliding rail 120 when the slider 2 is about to flip and slide to the side 105 of the frame body, but the sliding shaft 204 is still within the sliding rail 120. The notch 122 is arranged close to the bent and extended part of the frame body. The purpose is to enable the slider 2 to flip. First, it avoids the positioning column 110, and second, it reduces the overall height of the film applicator after the slider 2 flips.

[0039] Preferably, as Figure 1 、 4 -6 shows, the supporting part 140 has elasticity and is in a sheet-like inverted V-shaped or inverted U-shaped structure. One side of the supporting part 140 is connected to the frame body 101, and the highest point Z of the supporting part 140 is not higher than the top D of the positioning column. When the slider 2 slides to the position of the supporting part 140, the roller 201 will surely exert pressure on the supporting part 140. The lowest point G of the roller is lower than the highest point Z of the supporting part. At this time, the sliding rail 120 is horizontally fixed. Therefore, the supporting part 140 needs to have a certain elasticity to facilitate the passage of the slider 2. In the plastic field, a sheet-like inverted V-shaped or inverted U-shaped structure is more likely to have elasticity while providing a certain support. Other shape structures that can achieve the same function can also be substituted. The highest point Z of the supporting part 140 is not higher than the top D of the positioning column to prevent the screen protection film from detaching from the positioning column 110 and affecting film application.

[0040] Preferably, as Figure 1 、 4 、6 shows, on both sides 102 and 104 of the frame body 1 provided with the first limiting strip 150, a second limiting strip 160 is further provided. The second limiting strip 160 is arranged inside the frame body 1 and is parallel to the first limiting strip 150 in space. Second limiting grooves 260 matching the second limiting strip 160 are provided at both ends of the slider 2. The purpose of the second limiting strip 160 and the second limiting grooves 260 is the same as that of the first limiting strip 150 and the first limiting grooves 250. The second limiting strip 160 is arranged inside the frame body 1 and is matched with the second limiting grooves 260 provided on the slider 2 to clamp the slider 2 and make the slider 2 more fixed in space.

[0041] Preferably, as Figure 1 、4 As shown in FIGS. 5 and 6, on the side 103 of the frame body 1 relatively far from the bent and extended slide rail, the number of positioning posts 110 is two, and a drawbar opening 133 is also provided. The drawbar opening 133 is for facilitating the pulling out of the drawbar of the screen protector, and it can be located below the two positioning posts 110 or between the two positioning posts.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
