The buffer member is connected to the base and supports the side of the positioning film near the installation area in the first direction. The buffer member is elastically expandable and contractable along the first direction, allowing the positioning film to compress when it is pressed close to the installation area, so that the protective film can approach and adhere to the target object in the installation area. In this utility model, the buffer member is retractable, making it easier for the end of the protective film near the buffer member to contact the target object when the positioning film is pressed to bring it closer, thereby improving the contact and adhesion effect between the protective film and the target object.

Description

Technical Field

[0001] This utility model relates to the field of film application equipment technology, and in particular to a film applicator. Background Technology

[0002] To prevent damage to the screens of mobile phones and other objects from impacts, tempered glass screen protectors are usually applied to the screens. Existing screen protectors come with release films on both sides at the factory; these two release films are a positioning film and a peel-off film, respectively.

[0003] The positioning film has positioning holes at both ends; the film applicator includes a base, a first positioning element, a second positioning element, and a support element; the base has an installation area for placing the target object; the first and second positioning elements are both connected to the base and are spaced apart on opposite sides of the length of the installation area; the first and second positioning elements are used to position the positioning film; the support element is connected to the base and is used to support the side of the positioning film close to the protective film.

[0004] When applying the film, first place the target object in the installation area, then fit the positioning holes at both ends of the positioning film onto the first positioning component and the second positioning component respectively. The support component supports one end of the positioning film, and the tear-off film is located on the side of the protective film closer to the installation area. This completes the installation of the positioning film assembly on the film applicator.

[0005] Next, first peel off the protective film, then press the positioning film to bring the protective film closer to the target object, and finally attach the protective film to the target object's display screen. Then peel off the positioning film to complete the film application.

[0006] However, due to the presence of the support, the end of the protective film closest to the support is not easy to get close to the target object, which can easily lead to the protective film not being able to meet the required adhesion to the target object. Utility Model Content

[0007] This utility model provides a film applicator, which aims to improve the adhesion between the protective film and the target object.

[0008] This utility model provides a film applicator for attaching a protective film from a positioning film assembly to a target object. The applicator includes a base, a first positioning member, a second positioning member, and a buffer member. The base has an installation area on one side along a first direction, where the target object is placed. The first and second positioning members are both connected to the base and spaced apart on opposite sides of the installation area along a second direction to position the positioning film. The buffer member is connected to the base and supports the side of the positioning film near the installation area in the first direction. The buffer member is elastically expandable and contractable along the first direction, allowing the positioning film to compress when it is forced close to the installation area, thus enabling the protective film to approach and adhere to the target object in the installation area. The second direction is perpendicular to the first direction.

[0009] Optionally, in the second direction, the buffer and the first positioning member are located on the same side of the mounting area; and / or, the buffer is a sponge.

[0010] Optionally, the buffer member is provided with a clearance hole, which penetrates the buffer member in the first direction; the first positioning member passes through the clearance hole, one end of the first positioning member is connected to the base, and the other end of the first positioning member protrudes from the buffer member to position the positioning film.

[0011] Optionally, in the first direction, the buffer member can move as a whole relative to the first positioning member to move closer to or further away from the base; wherein, when the buffer member moves closer to the base, it can abut against the base; when the buffer member moves away from the base, it can separate from the base and cause the first positioning member to exit the clearance hole.

[0012] Optionally, in the first direction, the length of the first positioning member and the length of the buffer member are both greater than the length of the second positioning member; the first positioning member is detachably connected to the base; and / or, the buffer member is detachably connected to the base.

[0013] Optionally, the base is provided with a first connection hole, and the first positioning member is pluggably disposed in the first connection hole.

[0014] Optionally, the applicator further includes an adhesive component connected to the base and used to adhere the positioning film; the adhesive component is located on the side of the first positioning component opposite to the second positioning component.

[0015] Optionally, the adhesive is located on one side of the base in a second direction.

[0016] Optionally, in the first direction, the base has a bottom surface and a bearing surface disposed opposite to each other, and the mounting area is at least a portion of the bearing surface; along the direction from the bottom surface to the bearing surface, the first positioning member, the second positioning member, and the buffer member all protrude from the bearing surface.

[0017] Optionally, the first positioning element is a first positioning post, which can be inserted into the first positioning hole of the positioning film to achieve positioning of the positioning film; and / or, the second positioning element is a second positioning post, which can be inserted into the second positioning hole of the positioning film to achieve positioning of the positioning film; and / or, the mounting area is provided with a mounting hole for accommodating and positioning the target object.

[0018] In the film applicator provided in this embodiment of the invention, the buffer member can support the protective film, thus functioning as a support member in the prior art. Simultaneously, the buffer member can retract, allowing the end of the protective film near the buffer member to more easily contact the target object when the protective film is pressed and positioned to bring it closer, thereby improving the contact and adhesion effect between the protective film and the target object.

[0031] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figures 1 to 4As shown, in one embodiment, the film applicator 10 is used to attach the protective film 202 on the positioning film 201 in the protective film assembly 20 to a target object. The film applicator 10 includes a base 1, a first positioning member 2, a second positioning member 3, and a buffer member 4. The base 1 has an installation area 11 for placing the target object. The first positioning member 2 and the second positioning member 3 are both connected to the base 1 and are spaced apart on opposite sides of the installation area 11 along a second direction. The first positioning member 2 and the second positioning member 3 are used to position the positioning film 201. The buffer member 4 is connected to the base 1 and is used to support the side of the positioning film 201 close to the installation area 11 in a first direction. The buffer member 4 can elastically expand and contract along the first direction, so that when the positioning film 201 is subjected to force and approaches the installation area 11, it can compress the buffer member 4 so that the protective film 202 can approach and attach to the target object in the installation area 11. The second direction is perpendicular to the first direction.

[0035] In this embodiment, the buffer 4 supports the protective film 202, functioning as a support in the prior art. Simultaneously, the buffer 4 is retractable, allowing the end of the protective film 202 near the buffer 4 to more easily contact the target object when the positioning film 201 is pressed to bring the protective film 202 closer to the target object, thereby improving the contact and adhesion effect between the protective film 202 and the target object.

[0036] Among them, Figure 1 In the example shown, the second direction is parallel to the X-axis, and the first direction is parallel to the Z-axis.

[0037] In addition, the first direction can refer to the thickness direction of the base 1, and the second direction can refer to the length direction of the base 1.

[0038] In a practical application scenario, the first direction is parallel to the vertical direction, and the second direction is parallel to the horizontal direction.

[0039] Furthermore, "the buffer 4 can elastically expand and contract along the first direction" means that the buffer 4 can contract along the first direction and can expand and return to its original position along the first direction after contraction.

[0040] It should be noted that during use, after the positioning film 201 is positioned by the first positioning member 2 and the second positioning member 3, the positioning film 201 can be held on the side of the mounting area 11 of the base 1 in the first direction. Specifically, the part of the positioning film 201 that covers the protective film 202 is held on the side of the mounting area 11. At this time, the protective film 202 is held on the side of the mounting area 11 in the first direction.

[0041] When the first direction is parallel to the vertical direction, the protective film 202 can be held on the upper side of the base 1.

[0042] "The buffer 4 supports the side of the positioning film 201 near the installation area 11 in the first direction" means that the buffer 4 supports the surface of the positioning film 201 near the protective film 202.

[0043] like Figure 3 and Figure 4 As shown, the protective film assembly 20 typically includes a protective film 202, a positioning film 201, an optical adhesive layer 203, and a peelable film 204; wherein, the optical adhesive layer 203 is disposed on the protective film 202; the peelable film 204 is disposed on the side of the optical adhesive layer 203 away from the protective film 202, and is used to cover and protect the optical adhesive layer 203; the positioning film 201 covers the side of the protective film 202 away from the optical adhesive layer 203, and the positioning film 201 is provided with a first positioning hole 205 and a second positioning hole 206, which are respectively located at opposite ends of the positioning film 201.

[0044] In use, first place the target object in the mounting area 11; then install the protective film assembly 20 on the applicator 10. At this time, the first positioning member 2 extends into the first positioning hole 205, the second positioning member 3 extends into the second positioning hole 206, the buffer member 4 supports the positioning film 201, and the tear-off film 204 is located on the side of the optical adhesive layer 203 close to the mounting area 11; then, tear off the tear-off film 204. At this time, the optical adhesive layer 203 remains on the protective film 202, and the support of the buffer member 4 prevents the optical adhesive layer 203 from contacting the target object in the mounting area 11; then, apply force to the positioning film 201 from the side of the positioning film 201 away from the protective film 202, press the positioning film 201 so that the optical adhesive layer 203 is close to the target object, and finally make the optical adhesive layer 203 adhere to the target object, thereby achieving the adhesion of the protective film 202 to the target object; then, tear off the positioning film 201 again, thereby achieving the film application operation on the target object.

[0045] It should be noted that, for ease of description, it is usually assumed that the protective film 202 has an optical adhesive layer 203 on the side used to stick the target object.

[0046] Furthermore, the protective film 202 can be a tempered glass film or other flexible protective film, and the target object can be an electronic product such as a mobile phone or tablet computer. The film applicator 10 of this embodiment makes it easier to attach ultra-thin tempered glass films or similar devices to target objects such as mobile phones.

[0047] like Figure 1 and Figure 2 As shown, in one embodiment, in a first direction, the base 1 has a bottom surface 12 and a bearing surface 13 disposed opposite to each other, and the mounting area 11 is at least a portion of the bearing surface 13; along the direction from the bottom surface 12 to the bearing surface 13, the first positioning member 2, the second positioning member 3 and the buffer member 4 all protrude from the bearing surface 13.

[0048] In use, the protective film assembly 20 is usually placed on the side where the bearing surface 13 is located. Along the direction from the bottom surface 12 to the bearing surface 13, the first positioning member 2, the second positioning member 3, and the buffer member 4 are all set to protrude from the bearing surface 13, which can facilitate the support and positioning of the positioning film 201 of the protective film 202.

[0049] When the first direction is parallel to the vertical direction, the bearing surface 13 can be the upper surface of the base 1, and the bottom surface 12 can be the lower surface of the base 1.

[0050] Additionally, the bearing surface 13 can be a plane, and it can be perpendicular to the first direction. Similarly, the bottom surface 12 can be a plane, and it can be perpendicular to the first direction.

[0051] In one embodiment, in the second direction, the buffer 4 and the first positioning member 2 are located on the same side of the mounting area 11. This makes it easier to apply the film. In use, the buffer 4 supports the end of the positioning film 201 that is positioned by the first positioning member 2. After the positioning film 201 is installed on the applicator 10, the height of the end supported by the first positioning member 2 can be greater than the height of the end supported by the second positioning member 3.

[0052] In one embodiment, the buffer 4 is a sponge. This can improve the contraction effect of the buffer 4 and also prevent the buffer 4 from damaging the positioning film 201 or the protective film 202.

[0053] In one embodiment, when the first positioning member 2 and the buffer member 4 are disposed on the same side, in the first direction, the lengths of both the first positioning member 2 and the buffer member 4 are typically set to be greater than the length of the first positioning member 2. In this case, for ease of transportation and other operations, the first positioning member 2 can be detachably connected to the base 1; and / or, the buffer member 4 can be detachably connected to the base 1.

[0054] The lengths of the first positioning member 2 and the buffer member 4 refer to their dimensions in the first direction after they are installed on the base 1.

[0055] In addition, after assembly, along the direction from the bottom surface 12 to the bearing surface 13, the length of the first positioning member 2 protruding from the bearing surface 13 and the length of the buffer member 4 protruding from the bearing surface 13 are both greater than the length of the second positioning member 3 protruding from the bearing surface 13.

[0056] like Figure 2 As shown, in one embodiment, the base 1 is provided with a first connecting hole 14, and the first positioning member 2 is pluggably disposed in the first connecting hole 14, thereby realizing the detachable connection between the first positioning member 2 and the base 1.

[0057] The first connecting hole 14 may be disposed on the bearing surface 13 and extend towards the bottom surface 12. Moreover, the first connecting hole 14 may be a blind hole.

[0058] "The first positioning member 2 is pluggably disposed in the first connecting hole 14" means that the first positioning member 2 can extend into the first connecting hole 14 to achieve its connection with the base 1; at the same time, after the first positioning member 2 extends into the first connecting hole 14, it can also be withdrawn from the first connecting hole 14 to achieve its disassembly from the base 1.

[0059] In one embodiment, the base 1 is provided with a second connecting hole, and the second positioning member 3 is disposed in the second connecting hole, thereby realizing the connection between the second positioning member 3 and the base 1.

[0060] The second positioning element 3 and the second connecting hole can be an interference fit. Alternatively, the second positioning element 3 and the second connecting hole can be pluggably connected.

[0061] In one embodiment, the first positioning member 2 is a first positioning post, which can be inserted into the first positioning hole 205 of the positioning film 201 to achieve positioning of the positioning film 201.

[0062] The first positioning post can be a cylindrical structure.

[0063] In addition, two first positioning members 2 are provided, which are spaced apart along a third direction, wherein the third direction is perpendicular to the second direction and perpendicular to the first direction. Figure 1 Of the directions shown, the third direction is parallel to the Y-axis.

[0064] In one embodiment, the second positioning member 3 is a second positioning post, which can be inserted into the second positioning hole 206 of the positioning film 201 to position the positioning film 201. The second positioning post can be a cylindrical structure. Additionally, two first positioning members 2 are provided, spaced apart along a third direction.

[0065] like Figure 1 and Figure 2 As shown, in one embodiment, the mounting area 11 is provided with mounting holes 15, which are used to accommodate and position the target object.

[0066] The mounting hole 15 can be a rectangular hole, with the first direction being its depth direction, the second direction being its length direction, and the third direction being its width direction.

[0067] In addition, the mounting hole 15 is a blind hole, and its bottom surface 12 can support the target object. Furthermore, the wall of the mounting hole 15 can be provided with a corresponding limiting structure to limit the installation position of the target object within it.

[0068] like Figure 2As shown, in one embodiment, the buffer 4 is provided with a clearance hole 41, which penetrates the buffer 4 in the first direction; the first positioning member 2 is disposed in the clearance hole 41, one end of the first positioning member 2 is connected to the base 1, and the other end of the first positioning member 2 protrudes out of the buffer 4 to position the positioning film 201.

[0069] This allows the buffer 4 to better support the end of the positioning membrane 201 that is positioned by the first positioning member 2. At the same time, when the buffer 4 elastically expands and contracts along the first direction, the first positioning member 2 and the wall of the clearance hole 41 can cooperate to limit and guide the movement, effectively preventing the buffer 4 from disengaging from the positioning membrane 201 due to deformation, and improving the support effect of the buffer 4 on the positioning membrane 201.

[0070] In one embodiment, in a first direction, the buffer 4 can move as a whole relative to the first positioning member 2 to approach or move away from the base 1; wherein, when the buffer 4 approaches the base 1, it can abut against the base 1; when the buffer 4 moves away from the base 1, it can separate from the base 1 and cause the first positioning member 2 to exit the clearance hole 41.

[0071] This allows for a detachable connection between the buffer component 4 and the base 1. It also facilitates the installation and removal of the buffer component 4 on the base 1, making it easier to maintain the film applicator 10.

[0072] It should be noted that when the first positioning member 2 exits the clearance hole 41, the first positioning member 2 disengages from the buffer member 4, and at this time, the removal operation of the buffer member 4 from the base 1 is completed. When the buffer member 4 is fitted onto the first positioning member 2 (i.e., the first positioning member 2 passes through the clearance hole 41) and moved to abut against the base 1, the installation operation of the buffer member 4 on the base 1 is completed.

[0073] In addition, when the buffer 4 is close to the base 1, it actually moves along the direction from the bearing surface 13 to the bottom surface 12; when the buffer 4 is away from the base 1, it actually moves along the direction from the bottom surface 12 to the bearing surface 13; when the buffer 4 touches the base 1, it actually touches the bearing surface 13.

[0074] It should be understood that when the first positioning member 2 passes through the clearance hole 41 and the buffer member 4 abuts against the base 1, when the buffer member contracts or expands, it can also move the first positioning member 2. However, at this time, the buffer member 4 moves only a portion relative to the first positioning member 2.

[0075] like Figure 1 and Figure 2 As shown, in one embodiment, the film applicator 10 further includes an adhesive member 5, which is connected to the base 1 and used to adhere the positioning film 201; the adhesive member 5 is located on the side of the first positioning member 2 opposite to the second positioning member 3.

[0076] This allows the protective film assembly 20 to be installed more stably on the applicator 10. At the same time, positioning it on the side of the first positioning member 2 opposite to the second positioning member 3 avoids interference from the adhesive member 5 during the operation of pressing the positioning film 201 to adhere the protective film 202 to the target object.

[0077] The adhesive component 5 can be double-sided adhesive, which is adhered to the base 1 and used to adhere the positioning film 201.

[0078] like Figure 1 and Figure 2 As shown, in one embodiment, the mounting area 11 is located on one side of the base 1 in a first direction; the adhesive 5 is located on one side of the base 1 in a second direction. In this way, surfaces of the base 1 in different directions can be utilized, thereby improving the utilization rate of space on the base 1 and helping to reduce the size of the base 1.

[0079] like Figure 1 and Figure 2 As shown, in one embodiment, in the second direction, the base 1 has a first side 16 and a second side 17 disposed opposite to each other. The first side 16 intersects the bearing surface 13 and the bottom surface 12, and the second side 17 intersects the bearing surface 13 and the bottom surface 12. The direction from the first side 16 to the second side 17 is the same as the direction from the first positioning member 2 to the second positioning member 3. An adhesive member 5 is disposed on the first side 16.

[0080] It should be understood that the above-mentioned settings can also be replaced in other ways, such as:

[0081] In other embodiments, the number of first positioning elements 2 can be one or more.

[0082] In other embodiments, the buffer 4 can also be an elastically expandable object such as a rubber component, a silicone component, a spring, or a sheet. Specifically, when the buffer 4 is a spring, it can be a helical spring, etc.; when the buffer 4 is a sheet, it can be a U-shaped sheet, etc.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
