[0033] Example:

[0034] like Figures 1 to 6 As shown, a film applicator includes a pushing component 200 and a base 100 assembled on the pushing component 200;

[0035] The base 100 has a receiving groove 110, and the receiving groove 110 is used to fix the electronic device 01 and the protective film 02;

[0036] The pushing assembly 200 includes a first roller 220 and a rolling track 230 connected to the first roller 220. The first roller 220 and the rolling track 230 are arranged on both sides of the base 100 along the thickness direction. In the thickness direction of the base 100, the projection of the first roller 220 is located in the rolling track 230.

[0037] When the base 100 moves along the first direction on the rolling track 230 , the first roller 220 pushes the protective film 02 so that the protective film 02 is attached to the electronic device 01 .

[0038] In this embodiment, the film applicator uses a rolling track 230, so that the base 100 can move on the rolling track 230. Compared with the relative movement of the base 100 and the first roller 220 through an ordinary slide rail, the rolling track 230 can ensure the smooth movement and alignment of the base 100, so that the force on the protective film 02 during the film application process is more even, thereby improving the film application accuracy and film application quality. At the same time, the rolling track 230 reduces the friction between the base 100 and the pushing component 200, which is more labor-saving when used, and further increases the film application efficiency.

[0039] The rolling track 230 may include a plurality of spherical, cylindrical or arc-shaped protrusions. By rotating the protrusions, the base 100 can roll relatively on the rolling track 230 instead of sliding, which can reduce friction and save effort.

[0040] The length extension direction of the receiving groove 110 and the length extension direction of the base 100 can be the same or different, and there can be an angle between the two. Preferably, the length extension direction of the receiving groove 110 is the same as the length extension direction of the base 100, so that the required length of the first roller 220 is shorter and the structural strength of the first roller 220 is high. The length and width of the receiving groove 110 can be equal, or the length and width of the receiving groove 110 can be adjusted to be suitable for different electronic devices 01.

[0041] The width direction of the base 100 forms an angle with the first direction. Preferably, the width direction of the base 100 is perpendicular to the first direction, the length direction of the base 100 is parallel to the first direction, and the length direction of the receiving groove 110 is parallel to the first direction.

[0042] Furthermore, to ensure that the base 100 moves along the first direction on the rolling track 230, a plurality of guide tracks extending along the first direction may be provided on the rolling track 230. The structure of the guide track may be various. For example, a groove or a protrusion may be provided on the surface of the rolling track 230 facing the base 100 to form a guide track. A protrusion or a groove matching the guide track may be provided on the side of the base 100 facing the rolling track 230. Alternatively, the rolling track 230 may be provided with protrusions or grooves at both ends perpendicular to the first direction to form a guide track. Both ends of the base 100 along the width direction fit into the guide track, thereby further reducing the error of the relative movement trajectory between the base 100 and the rolling track 230 and improving the film sticking accuracy and quality.

[0043] Furthermore, if Figure 3 and 5 As shown, the rolling track 230 includes a plurality of second rollers 231 spaced apart along the first direction, the axis of each second roller 231 is parallel to the axis of the first roller 220, and the axes of the second roller 231 and the first roller 220 form an angle with the first direction.

[0044] Preferably, the axis of each second roller 231 and the axis of the first roller 220 are perpendicular to the first direction.

[0045] Furthermore, if Figure 5 As shown, each second roller 231 includes a roller 2321 and protrusions 2322 disposed at both ends of the roller 2321. In the direction of the roller 2321 along the axis, the projection of each protrusion 2322 covers the projection of the roller 2321.

[0046] The base 100 perpendicular to the first direction is defined as the width direction of the base 100 , and both ends of the base 100 in the width direction abut against one side of each protrusion 2322 facing the roller 2321 .

[0047] Each raised portion 2322 forms a guide track, and both ends of the base 100 along the width direction can fit into the guide track, so that the base 100 can move in the first direction along the rolling track 230, reducing the error during movement between the base 100 and the rolling track 230, and improving the film sticking accuracy and quality.

[0048] In the direction of the roller 2321 along the axis, the projection of the protrusion 2322 can be circular, polygonal or other shapes, as long as the projection of each protrusion 2322 covers the projection of the roller 2321 .

[0049] Furthermore, if Figure 1 and 3 As shown, the pushing assembly 200 further includes a fixing member 210 , the first roller 220 and the second roller 231 are clamped on the fixing member 210 , and the base 100 is disposed inside the fixing member 210 .

[0050] In the present embodiment, the fixing member 210 is in the shape of a frame with two ends through. In other embodiments, the fixing member 210 can also be in the shape of a fully enclosed or semi-enclosed cover, or the fixing member 210 can also be in other shapes. Among them, the weight of the fixing member 210 in the shape of a frame is lighter than that of the fixing member 210 in the shape of a cover, saving materials and reducing costs. At the same time, the base 100 is inserted into the fixing member 210. Since the first roller 220 and the second roller 231 are arranged on both sides of the base 100 in the thickness direction, the fixing member 210 allows the base 100 to be limited in the thickness direction of the base 100 by the first roller 220 and the second roller 231. The base 100 can move on the rolling track 230 without shaking in the thickness direction of the base 100.

[0051] Furthermore, if Figures 1 to 3 As shown, the fixing member 210 includes a main body 211, an extension portion 212 and a fixing portion 213 connected in sequence, the extension portion 212 extends from the main body 211 along a first direction, and the fixing portion 213 and the extension portion 212 are respectively arranged on both sides of the base 100 along the thickness direction;

[0052] When the base 100 moves along the first direction on the rolling track 230, the first roller 220 moves from the first position of the base 100 to the second position of the base 100, and the receiving groove 110 is arranged between the first position and the second position of the base 100; when the first roller 220 is located at the first position of the base 100, the base 100 is at least partially arranged between the fixing portion 213 and the extension portion 212.

[0053] In this embodiment, when the base 100 moves along the first direction on the rolling track 230, the first roller 220 moves from the first position of the base 100 to the second position of the base 100, so that the first roller 220 pushes the protective film 02, that is, in the thickness direction of the base 100, the overlapping part between the projection of the base 100 and the projection of the rolling track 230 becomes smaller and smaller.

[0054] When the first roller 220 is located at the first position of the base 100, it is in the initial state of film application. The base 100 is at least partially inserted between the fixing portion 213 and the extension portion 212 to ensure a stable connection between the pushing assembly 200 and the base 100. The fixing member 210 adopts a frame structure, which is lighter than a fixing member 210 in the shape of a cover.

[0055] Preferably, one end of the base 100 close to the second position is disposed between the fixing portion 213 and the extending portion 212 .

[0056] Furthermore, if Figure 5 As shown, the base 100 further includes a limiting portion 120 disposed at a first position. When the first roller 220 is located at the first position of the base 100 , the limiting portion 120 abuts against a side of the first roller 220 facing the first position of the base 100 .

[0057] When the base 100 moves along the first direction on the rolling track 230, the first roller 220 moves from the first position of the base 100 to the second position of the base 100, the receiving groove 110 is arranged between the first position and the second position of the base 100, and the limiting portion 120 limits the sliding stroke of the first roller 220, ensuring that the first roller 220 stays at the first position of the base 100, preventing the base 100 from continuing to move in a direction away from the first direction.

[0058] The limiting portion 120 matches the first roller 220. In this embodiment, the cross section of the limiting portion 120 along the axis of the first roller 220 is arc-shaped. In other embodiments, the cross section of the limiting portion 120 along the axis of the first roller 220 can also be a rectangular surface or an inclined surface.

[0059] Preferably, if Figure 1 As shown, a plurality of roller assembly holes are provided on the body 211 , some of the roller assembly holes are used to assemble the first roller 220 , and another part of the roller assembly holes are used to assemble the second roller 231 .

[0060] The roller assembly hole is in the shape of a gourd hole, that is, the roller assembly hole includes a belly and a neck. The belly of the roller assembly hole for assembling the first roller 220 and the belly of the roller assembly hole for assembling the second roller 231 are arranged opposite to each other, which facilitates the installation of the first roller 220 and the second roller 231 and ensures that the first roller 220 and the second roller 231 will not slip when in use.

[0061] Furthermore, if Figure 1 As shown, a gripping portion 160 is provided at one end of the base 100 along the first direction. Preferably, a gripping portion 160 is provided at one end of the base 100 close to the first position.

[0062] The grip portion 160 facilitates the user to exert force to pull the base 100, which is more labor-saving than direct pulling, and the base 100 can move more smoothly relative to the rolling track 230. As an example, the grip portion 160 is in the shape of an arc-shaped handle, so that the user has a better grip. It should be noted that the shape of the grip portion 160 can also be a square frame, various deformations of a square frame or an arc, or other shapes, and the utility model is not limited thereto.

[0063] In other embodiments, the gripping portion 160 may also be disposed on an end of the base 100 close to the second position, and the base 100 may be moved by pushing or pulling.

[0064] Furthermore, a plurality of fixing components are provided on one side of the base 100 facing the receiving groove 110 , and the fixing components are used to fix the protective film 02 .

[0065] In this embodiment, if Figures 1 to 2 As shown, the fixing assembly includes a first fixing assembly 130 and a second fixing assembly 140 . The first fixing assembly 130 and the second fixing assembly 140 are used to fix the release film 03 , and the release film 03 is attached to the surface of the protective film 02 .

[0066] The plurality of second fixing components 140 and the plurality of first fixing components 130 are disposed on both ends of the base 100 extending along the length direction.

[0067] It should be known that there can be multiple release films 03. When the protective film 02 is not in use, the release films 03 and the protective film 02 are laminated and bonded. The protective film 02 has an adhesive surface, which can be bonded to the electronic device 01. For example, Figure 6As shown, in this embodiment, only one release film 03 is provided, and the release film 03 is bonded to the adhesive surface and does not need to be fixed by the first fixing component 130. A tear strip is connected to one end of the release film 03, and the tear strip and the release film 03 are stacked. The end of the tear strip that is not connected to the release film 03 exceeds the other end of the release film 03. The user can separate the release film 03 from the protective film 02 by pulling the end of the tear strip that is not connected to the release film 03. After tearing, the release film 03 is suspended on the second fixing component 140. When in use, the release film 03 is fixed by the fixing component, so that the adhesive surface of the protective film 02 is aligned with the electronic device 01 to prevent the protective film 02 from deviating from the electronic device 01.

[0068] The first fixing component 130 may include a plurality of fixing protrusions disposed on both ends of the base 100 along the first direction. The fixing protrusions can be inserted into the positioning holes of the release film 03 to fix the release film 03 on a plane parallel to the length extension direction of the base 100 .

[0069] The second fixing assembly 140 includes a plurality of hook-shaped portions disposed on one end of the base 100 close to the first position, and the hook-shaped portions are used to hang the torn release film 03 .

[0070] It is understandable that in other embodiments, the first fixing component 130 and the second fixing component 140 may be hook-shaped or other shaped protrusions, and the first fixing component 130 and the second fixing component 140 may be disposed on the top surface or side of the base 100 .

[0071] Furthermore, an avoidance position 150 is provided in the receiving groove 110 , and the avoidance position 150 is used to avoid the lens assembly of the electronic device 01 .

[0072] The avoidance position 150 can prevent the lens assembly of the electronic device 01 from contacting the bottom of the receiving groove 110 when applying the film, thereby avoiding friction damage to the lens assembly. It can also place the electronic device 01 stably in the receiving groove 110, thereby avoiding shaking of the electronic device 01 due to the protrusion of the lens assembly when applying the film.

[0073] The avoidance position 150 can be a groove formed in the bottom of the receiving groove 110, or an opening penetrating the bottom of the receiving groove 110 in the thickness direction. Providing the avoidance position 150 can also reduce the weight of the film sticking assembly, especially when the avoidance position 150 is an opening penetrating the bottom of the receiving groove 110 in the thickness direction, the weight of the base 100 is reduced, less materials are required for manufacturing, and the cost is saved.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
