Description

Technical Field

[0001] This utility model relates to the field of film applicator technology, specifically to a film applicator and film applicator device. Background Technology

[0002] Mobile phone screens are prone to scratches and bumps during use, affecting the phone's appearance and lifespan. Therefore, a protective film needs to be applied to the screen manually or with a screen protector applicator. Screen protector applicators on the market have a slot to hold the phone, and an elastic element is installed within the slot. The deformation of the elastic element in contact with the device clamps and fixes the device in place. However, when the elastic element is repeatedly compressed and released over a long period, its structure undergoes irreversible creep, losing its elasticity. This causes the phone to loosen its position in the slot, leading to misalignment between the screen protector and the phone screen during application, affecting the quality of the application. Summary of the Invention

[0003] In view of the above problems, this utility model provides a film applicator and film applicator device to solve the problem of poor film applicator quality caused by unstable connection between the film applicator and electronic equipment due to long-term use in existing film applicator devices.

[0004] According to a first aspect of the present invention, a film applicator is provided, the film applicator comprising:

[0005] The mounting base has a mounting groove for accommodating electronic devices and protective film assemblies, and the mounting groove has at least two opposing side walls;

[0006] At least one positioning element, the positioning element being disposed within the mounting groove and connected to the side wall;

[0007] At least one elastic element is disposed within the mounting groove, and a clearance groove is provided on the side wall. The clearance groove is provided corresponding to the elastic element to accommodate the elastic element at least when the elastic element deforms, and at least a portion of the elastic element is placed outside the clearance groove. The distance between the side of the elastic element away from the clearance groove and the opposite side wall is less than the distance between the positioning element and the opposite side wall.

[0008] In one alternative embodiment, a gap is formed between the elastic element and the sidewall of the mounting groove, the elastic element comprising a connecting end and an abutting end;

[0009] The connecting end is connected to the bottom of the mounting groove, and the abutting end extends toward the opening of the mounting groove.

[0010] In one alternative embodiment, the abutting end has a protrusion on the side away from the clearance groove;

[0011] The distance between the positioning element and the opposite sidewall is greater than the distance between the protrusion and the opposite sidewall.

[0012] In one alternative, the protrusion is located at the end of the abutment near the groove.

[0013] In one alternative embodiment, the abutting end is provided with a guide slope on the side away from the clearance groove, and the guide slope extends obliquely from the groove opening toward the bottom of the groove toward the side gradually away from the clearance groove.

[0014] In one alternative embodiment, the protrusion has an abutment surface extending from the groove opening toward the groove bottom, the minimum distance between the abutment surface and the groove bottom being greater than or equal to half the maximum length dimension of the elastic member to the groove bottom.

[0015] In one alternative embodiment, the applicator includes: a plurality of elastic elements and a plurality of positioning elements; the elastic elements and the positioning elements are spaced apart along the length direction of the sidewall.

[0016] In one alternative embodiment, the distance between the side of the connecting end away from the clearance groove and the opposite sidewall is greater than the distance between the positioning member and the opposite sidewall.

[0017] In one alternative, one end of the elastic member is located within the clearance groove and connected to one of the sidewalls, while the other end, away from the clearance groove, faces the opposite sidewall.

[0018] According to a second aspect of the present invention, a film applicator is provided, the film applicator comprising any of the film applicators described in the first aspect above and a protective film assembly, the protective film assembly being placed at the bottom of the mounting groove.

[0019] This utility model embodiment uses two structures, a positioning component and an elastic component, to assemble and fix electronic devices of different sizes to the mounting slot. By setting the positioning component, the maximum size of the electronic device assembled with the mounting base is limited, thereby limiting the degree to which the electronic device can compress the elastic component. This prevents the elastic component from being compressed to the extreme, which would damage its internal structure, thus protecting the elastic component and extending its service life.

[0020] In addition, by setting positioning elements, the maximum size of electronic devices that can be placed in the mounting slot is limited, which prevents excessively large electronic devices from being forcibly installed into the mounting slot and ensures that the structure of the applicator and electronic devices will not be damaged due to mutual squeezing.

[0021] Finally, by setting a clearance groove on the side wall of the mounting groove, the elastic element can be offset towards the clearance groove and enter the clearance groove when subjected to force. The clearance groove provides deformation space for the elastic element, avoids excessive compression deformation of the elastic element, and further extends the service life of the elastic element.

In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, specific embodiments of this utility model are given below.

[0040] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention. Example 1

[0041] Please see Figures 1-10 The film applicator 100 provided by this utility model includes: a mounting base 1, at least one positioning member 2, and at least one elastic member 3. Figure 1 and Figure 7 As shown, a mounting slot 11 is provided on the mounting base 1. When the electronic device 200 to be coated with a screen protector is assembled with the screen protector applicator 100, the mounting slot 11 is used to accommodate the electronic device 200 and the protective film assembly 300. The electronic device 200 includes electronic products such as mobile phones and tablets that require screen protector application. During screen protector application, the protective film assembly 300 is first placed in the mounting slot 11, then the screen of the electronic device 200 is positioned with the bottom 13 of the mounting slot 11 facing it, and the electronic device 200 is assembled into the mounting slot 11, so that the screen of the electronic device 200 and the protective film assembly 300 are adhered together.

[0042] like Figure 3 As shown, the mounting groove 11 has at least two opposing side walls. The positioning member 2 is disposed in the mounting groove 11 and is connected to the side wall. The elastic member 3 is disposed in the mounting groove 11 to accommodate the elastic member 3 at least when the elastic member 3 deforms. An avoidance groove 14 is provided on the side wall of the mounting groove 11. The avoidance groove 14 is provided corresponding to the elastic member 3, and at least part of the elastic member 3 is placed outside the avoidance groove 14. The distance between the side of the elastic member 3 away from the avoidance groove 14 and the opposite side wall is less than the distance between the positioning member 2 and the opposite side wall.

[0043] like Figure 4As shown, a relief groove 14 is formed by recessing one side wall of the mounting groove 11 away from the other side wall. The elastic member 3 is placed inside the mounting groove 11, and in the opposite direction of the two opposite side walls of the mounting groove 11, part of the elastic member 3 is located inside the relief groove 14, and part of the elastic member 3 is located outside the relief groove 14. The space between the positioning member 2 and the opposite side wall, and the space between the side of the elastic member 34 away from the relief groove 14 and the opposite side wall, are used for assembling the electronic device 200. When the electronic device 200 is assembled into the mounting groove 11, the side wall of the electronic device 200 first contacts the elastic member 3. After being squeezed by the electronic device 200, the elastic member 3 shifts in the direction of the relief groove 14 and enters the relief groove 14. The elastic member 3 provides a clamping force to the side wall of the electronic device 200 to fix the electronic device 200 in the mounting groove 11.

[0044] When the elastic element 3 is pressed by the electronic device 200 and shifted towards the relief groove 14, the state of the elastic element 3 changes from as follows: Figure 5 The state change shown is as follows Figure 8 As shown, the distance between the side of the elastic element 3 away from the clearance groove 14 and the opposite sidewall gradually increases. When the distance between the side of the elastic element 3 away from the clearance groove 14 and the opposite sidewall is less than the distance between the positioning element 2 and the opposite sidewall, the positioning element 2 does not contact the sidewall of the electronic device 200. The pressing force formed by the elastic element 3 pressing against the sidewall of the electronic device 200 fixes the electronic device 200 in the mounting groove 11, preventing the electronic device 200 from moving and affecting the film application effect of the protective film assembly 300 and the screen of the electronic device 200.

[0045] When the electronic device 200 is large, during the process of installing the electronic device 200 into the mounting slot 11, the side wall of the electronic device 200 contacts the positioning member 2. At this time, the elastic member 3 has shifted into the clearance slot 14. The distance between the side of the elastic member 3 away from the clearance slot 14 and the opposite side wall is equal to the distance between the positioning member 2 and the opposite side wall. That is, both the positioning member 2 and the elastic member 3 are in contact with the side wall of the electronic device 200, and both apply a compressive force to the side wall of the electronic device 200 to make the electronic device 200 stably fixed in the mounting slot 11.

[0046] like Figure 9 and Figure 10 As shown, due to the different sizes of the electronic devices 200, when the size of the electronic device 200 is less than the distance between the positioning member 2 and the opposite sidewall, in the opposite direction of the two sidewalls, the sidewall of the electronic device 200 only abuts against the elastic member 3, and the elastic member 3 applies a pressing force to the electronic device 200 to stably fix the electronic device 200 in the mounting groove 11; when the size of the electronic device 200 is greater than or equal to the distance between the positioning member 2 and the opposite sidewall, such as Figure 7 and Figure 8As shown, the positioning member 2 and the elastic member 3 are in contact with the side wall of the electronic device 200 at the same time, and both exert pressure on the side wall of the electronic device 200 to fix the electronic device 200 in the mounting groove 11. This invention uses two structures, a positioning element 2 and an elastic element 3, to assemble and fix electronic devices 200 of different sizes to the mounting slot 11. The positioning element 2 limits the maximum size of the electronic device 200 assembled with the mounting base 1, thereby limiting the degree to which the electronic device 200 can compress the elastic element 3. This prevents the elastic element 3 from being repeatedly subjected to extreme compression during use, which could damage its internal structure and thus protect the elastic element 3 and extend its service life. In addition, the positioning element 2 limits the maximum size of the electronic device 200 that can be placed in the mounting slot 11, preventing excessively large electronic devices 200 from being forcibly installed into the mounting slot 11. This ensures that the film applicator 100 and the electronic device 200 will not damage their structures due to mutual compression. Finally, by providing a relief groove 14 on the side wall of the mounting slot 11, the elastic element 3 can shift into the relief groove 14 when subjected to force. The relief groove 14 provides deformation space for the elastic element 3, preventing it from being excessively compressed and deformed, further extending the service life of the elastic element 3.

[0047] In this embodiment, as Figure 5 As shown, a gap is formed between the elastic element 3 and the side wall of the mounting groove 11. The elastic element 3 includes a connecting end 31 and an abutting end 32. The connecting end 31 is connected to the bottom 13 of the mounting groove 11, and the abutting end 32 extends toward the opening 12 of the mounting groove 11.

[0048] In the insertion direction of the electronic device 200 into the mounting groove 11, one end of the elastic member 3 is fixedly connected to the bottom 13 of the mounting groove 11, and the other end extends to the opening 12 of the mounting groove 11. The side of the elastic member 3 near the clearance groove 14 is spaced a certain distance from the side wall, so that when the side wall of the electronic device 200 and the side of the elastic member 3 away from the clearance groove 14 are pressed into contact, the elastic member 3 shifts into the clearance groove 14 and does not press against the side wall of the mounting groove 11.

[0049] The end of the elastic element 3 that is connected to the bottom 13 of the mounting groove 11 is the connecting end 31, and the other end located at the opening 12 of the mounting groove 11 is the abutting end 32. When the side wall of the electronic device 200 and the elastic element 3 are pressed against each other, the abutting end 32 contacts the side wall of the electronic device 200.

[0050] Under the action of external force, the electronic device 200 is assembled into the mounting groove 11, and its sidewall contacts the abutment end 32, generating a continuous compressive force on the electronic device 200, such as... Figure 10As shown, the contact area between the electronic device 200 and the elastic element 3 gradually increases during the assembly process, allowing the electronic device 200 to be subjected to a relatively uniform compressive force as it continues to be assembled into the bottom of the groove 13. The abutting end 32 gradually shifts into the clearance groove 14 during assembly. The compressive force exerted by the abutting end 32 on the side wall of the electronic device 200 can be decomposed into a horizontal clamping force and a vertical resistance force. The horizontal direction is the relative direction of the two side walls of the mounting groove 11, and the vertical direction is the insertion direction of the electronic device 200 into the mounting groove 11. The horizontal clamping force acting on the side wall of the electronic device 200 stably fixes the electronic device 200 within the mounting groove 11; the external force counteracts the vertical resistance force, allowing the electronic device 200 to continue being installed into the mounting groove 11, ensuring that the electronic device 200 is installed into the mounting groove 11 and remains stable within it. The elastic element 3 has a connecting end 31 and an abutting end 32 at both ends of the insertion direction of the electronic device 200 into the mounting groove 11, so as to ensure that the electronic device 200 enters the mounting groove 11 accurately and smoothly along the preset trajectory under the action of external force.

[0051] When the electronic device 200 presses against the abutting end 32, the abutting end 32 shifts as a whole toward the clearance groove 14 and enters the clearance groove 14. The distance between the side of the elastic member 3 away from the clearance groove 14 and the side wall of the opposite mounting groove 11 becomes wider, so that the space between the elastic member 3 and the side wall of the opposite mounting groove 11 can accommodate the electronic device 200 and can clamp and fix the electronic device 200 in the mounting groove 11.

[0052] In one embodiment of this utility model, such as Figure 5 As shown, a protrusion 321 is provided on the side of the abutment end 32 away from the relief groove 14; the distance between the positioning member 2 and the opposite side wall is greater than the distance between the protrusion 321 and the opposite side wall.

[0053] A protrusion 321 is formed on the side of the abutment end 32 away from the clearance groove 14, extending horizontally towards the side wall of the opposite mounting groove 11. This ensures that, in the opposite direction of the two side walls of the mounting groove 11, the distance between the side of the protrusion 321 away from the clearance groove 14 and the opposite side wall is less than the distance between the positioning member 2 and the opposite side wall. This allows the film applicator 100 to fix the film onto electronic devices 200 of different sizes. During assembly, the side of the protrusion 321 away from the clearance groove 14 contacts the side wall of the electronic device 200, clamping the electronic device 200. This avoids the elastic member 3 being too thick in the opposite direction of the two side walls of the mounting groove 11, which would result in insufficient offset of the elastic member 3 and an inability to stably clamp the electronic device 200.

[0054] like Figure 5As shown, a guide ramp 322 is provided on the side of the abutment end 32 away from the clearance groove 14. The guide ramp 322 extends obliquely from the groove opening 12 towards the groove bottom 13, gradually moving away from the clearance groove 14. The guide ramp 322 is used to contact the side wall of the electronic device 200 to guide the electronic device 200 into the mounting groove 11. The guide ramp 322 extends gradually away from the clearance groove 14 from the groove opening 12 towards the groove bottom 13 to guide the electronic device 200 to move smoothly into the mounting groove 11 along the insertion direction. Under the action of external force, the external force acts on the guide ramp 322 through the electronic device 200, forcing the abutment end 32 of the elastic member 3 to deflect and enter the clearance groove 14 until the electronic device 200 is fully in place in the mounting groove 11.

[0055] In one implementation of this embodiment, such as Figure 5 As shown, the protrusion 321 has an abutment surface 323 extending from the slot opening 12 to the slot bottom 13. The minimum distance between the abutment surface 323 and the slot bottom 13 is greater than or equal to half the maximum length dimension of the elastic member 3 to the slot bottom 13. The minimum distance between the abutment surface 323 and the slot bottom 13 is the distance between the end of the abutment surface 323 away from the slot opening 12 and the slot bottom 13 in the insertion direction of the electronic device 200 into the mounting slot 11.

[0056] During the insertion of the electronic device 200 into the mounting slot 11, the contact end 32 and the side wall of the electronic device 200 are pressed and offset. At this time, the deformation of the elastic element 3 varies at different positions, and the elastic deformation gradually decreases from the slot opening 12 to the slot bottom 13, forming a progressive clamping force on the electronic device 200. During the assembly process, the protrusion 321 and the electronic device 200 are pressed and contacted, causing the elastic element 3 to shift. The protrusion 321 is located at the end of the contact end 32 closest to the slot opening 12, maintaining the maximum distance between the protrusion 321 and the connecting end 31. This minimizes the deformation of the connecting end 31 caused by the offset of the protrusion 321 and the electronic device 200 during pressing and clamping, preventing excessive elastic deformation on the connecting end 31 from causing breakage at the connection between the connecting end 31 and the slot bottom 13, thus protecting the connecting end 31. In addition, positioning the protrusion 321 close to the slot opening 12 can prevent the electronic device 200 from falling out of the mounting slot 11.

[0057] The side of the protrusion 321 closest to the slot 12 in the vertical direction is a guide slope 322. The area on the protrusion 321 that is in contact with the side wall of the electronic device 200 is an abutment surface 323. In the vertical direction, the lower end of the guide slope 322 and the upper end of the abutment surface 323 are connected. The distance between the lower end of the abutment surface 323 and the bottom of the slot 13 is greater than or equal to half of the maximum length dimension from the elastic member 3 to the bottom of the slot 13.

[0058] The distance between the abutment surface 323 and the opposite side wall of the mounting groove 11 is less than the distance between the positioning member 2 and the opposite side wall of the mounting groove 11. When the electronic device 200 is fixed in the mounting groove 11, the abutment surface 323 and the side wall of the electronic device 200 are in contact by pressure. The minimum distance between the abutment surface 323 and the bottom of the groove 13 is greater than or equal to half the maximum length dimension of the elastic member 3 to the bottom of the groove 13. That is, the distance between the abutment surface 323 and the opposite side wall of the mounting groove 11 is less than the distance between the area of ​​the elastic member 3 away from the clearance groove 14 (excluding the abutment surface 323) and the side wall of the other mounting groove 11. This ensures that when the electronic device 200 is correctly installed and fixed in the groove, there is a certain space distance between the other areas of the elastic member 3 (excluding the abutment surface 323) and the side wall of the electronic device 200. This prevents the presence of the elastic member 3 from hindering the adhesion between the protective film assembly 300 and the edge of the screen when the screen is attached.

[0059] The distance between the side of the connecting end 31 away from the clearance groove 14 and the opposite sidewall is greater than the distance between the positioning member 2 and the opposite sidewall. The sidewall of the electronic device 200 assembled into the mounting groove 11 is relatively large. The elastic member 3 and the positioning member 2 simultaneously squeeze and clamp the sidewall of the electronic device 200. The fact that the distance between the side of the connecting end 31 away from the clearance groove 14 and the opposite sidewall is greater than the distance between the positioning member 2 and the opposite sidewall ensures that there is a certain gap between the sidewall of the electronic device 200 and the connecting end 31, thus preventing the screen edge of the electronic device 200 from contacting the connecting end 31 and affecting the edge bonding effect of the screen edge and the protective film assembly 300.

[0060] In one implementation of this embodiment, such as Figure 5 As shown, the connection end 31 and the bottom 13 of the mounting groove 11 are integrated and connected to avoid friction between the elastic element 3 and the bottom 13 of the mounting groove 11 when the electronic device 200 is repeatedly inserted and removed from the mounting base 1, thereby eliminating surface peeling and cracks caused by minute displacement and improving the service life of the elastic element 3.

[0061] like Figure 8 As shown, the contact surface 323 is curved. When the screen of the electronic device 200 is curved, the curved contact surface 323 is used to contact the side wall of the electronic device 200 to avoid the screen from contacting the elastic element 3 and thus affecting the film application effect.

[0062] In one implementation of this embodiment, when the film applicator 100 has an elastic element 3 and a positioning element 2, the elastic element 3 and the positioning element 2 are disposed close to the same side wall of the mounting groove 11 on opposite side walls. When assembled with the electronic device 200, the elastic element 3 and the positioning element 2 squeeze and clamp the electronic device 200 with the opposite side wall to fix the electronic device 200.

[0063] In another implementation of this embodiment, such as Figure 2 As shown, the film applicator 100 includes multiple elastic elements 3 and multiple positioning elements 2; the elastic elements 3 and positioning elements 2 are spaced apart along the length of the sidewall. The elastic elements 3 are located at both ends of the sidewall, and at least one positioning element 2 is located in the middle of the sidewall.

[0064] Along the length of the sidewall of the mounting groove 11, elastic members 3 are respectively provided at both ends of the sidewall of the mounting groove 11 to achieve multi-contact compression of the sidewall of the electronic device 200, avoiding damage to the electronic device 200 caused by the compression force acting on a small area of ​​the sidewall of the electronic device 200. Similarly, positioning members 2 are respectively provided at both ends of the sidewall of the mounting groove 11 to achieve multi-contact compression of the sidewall of the large-sized electronic device 200, protecting the electronic device 200.

[0065] A positioning element 2 is provided in the middle area of ​​the side wall of the mounting groove 11. When the film applicator 100 clamps and fixes a large electronic device 200, it can further distribute the clamping force to multiple areas of the side wall of the electronic device 200, thus protecting the electronic device 200. At the same time, it further enhances the strength of the side wall and prevents the film applicator 100 from being damaged due to the large size of the electronic device 200.

[0066] In another implementation, multiple clearance grooves 14 are symmetrically arranged on opposite side walls of the mounting groove 11. Each clearance groove 14 corresponds to an elastic member 3, and one elastic member 3 is partially housed within a clearance groove 14. The space between the protrusions 321 of the opposite elastic members 3 is used to accommodate the electronic device 200. The electronic device 200 installed between the protrusions 321 is clamped and fixed by the opposite elastic members 3, preventing the electronic device 200 from shaking within the mounting groove 11 and affecting the film application effect. Multiple positioning members 2 are symmetrically distributed on opposite side walls of the mounting groove 11. When the electronic device 200 is not installed in the mounting groove 11, the distance between two opposite positioning members 2 is greater than the distance between two opposite elastic members 3. This embodiment increases the contact area between the electronic device 200 and the elastic members 3 and positioning members 2 by symmetrically arranging multiple elastic members 3 and multiple positioning members 2 along the length of the side wall of the mounting groove 11, protecting the electronic device 200 and enhancing the strength of the side wall of the mounting groove 11. Multiple elastic elements 3 and multiple positioning elements 2 are provided on the opposite side walls of the mounting groove 11, making it difficult for the electronic device 200 to loosen or shift during use. At the same time, the multiple elastic elements 3 and multiple positioning elements 2 work together to ensure that the electronic device 200 can still be stably fixed in the mounting groove 11 even if one of the elastic elements 3 becomes fatigued. The elastic elements 3 and positioning elements 2 can be used to adapt to electronic devices 200 of different sizes, improving the versatility and applicability of the film applicator 100. In addition, the elastic elements 3 can effectively absorb external impacts and vibrations, further protecting the electronic device 200 from damage.

[0067] In another implementation of this embodiment, multiple elastic members 3 and multiple positioning members 2 are symmetrically arranged on both sides of the mounting groove 11 in the width direction. The elastic members 3 and positioning members 2 are used to clamp and fix the electronic device 200 in the width direction. On one side wall of the mounting groove 11 in the length direction, the electronic device 200 is fixed to the other side wall by means of an elastic part and an interference fit, so as to prevent the electronic device 200 from sliding in the length direction of the mounting groove 11.

[0068] In another implementation of this embodiment, one end of the elastic member 3 is located within the clearance groove 14 and connected to one side wall of the mounting groove 11, while the other end, away from the clearance groove 14, faces the opposite side wall. When the electronic device 200 is placed in the mounting groove 11, the end of the elastic member 3 away from the clearance groove 14 abuts against the side wall of the electronic device 200. The elastic member 3 as a whole undergoes elastic deformation as it shifts into the clearance groove 14, thus compressing and supporting the side wall of the electronic device 200. The elastic member 3 includes a spring structure, a sheet structure, etc.

[0069] This embodiment of the invention uses two structures—a positioning member 2 and an elastic member 3—to assemble and fix electronic devices 200 of different sizes to the mounting slot 11. The positioning member 2 limits the maximum size of the electronic device 200 assembled with the mounting base 1, thereby limiting the degree to which the electronic device 200 can compress the elastic member 3. This prevents the elastic member 3 from being excessively compressed, which could damage its internal structure, thus protecting the elastic member 3 and extending its service life. Furthermore, the positioning member 2 limits the maximum size of the electronic device 200 that can be placed in the mounting slot 11, preventing excessively large electronic devices 200 from being forcibly installed into the mounting slot 11. This ensures that the applicator 100 and the electronic device 200 will not damage their structures due to mutual compression. Finally, by providing a clearance groove 14 on the side wall of the mounting slot 11, the elastic member 3 can shift towards and into the clearance groove 14 when subjected to force. The clearance groove 14 provides deformation space for the elastic member 3, preventing excessive compression and deformation, further extending its service life. Example 2

[0070] Based on the film applicator 100 provided in Embodiment 1 above, this embodiment provides a film applicator device, which includes any of the film applicators 100 provided in Embodiment 1 above, and a protective film assembly 300, which is placed at the bottom 13 of the mounting groove 11.

[0071] like Figure 2 and Figure 3 As shown, the film applicator 100 also includes a limiting platform 4, such as Figure 3As shown, the lower ends of the limiting platform 4 and the positioning component 2 are connected. The upper surface of the limiting platform 4 contacts the electronic device 200. The protective film assembly 300 is placed at the bottom of the groove 13 so that the electronic device 200 and the protective film assembly 300 can be assembled with a gap. That is, when the electronic device 200 is assembled in the mounting groove 11, a certain distance is maintained between the protective film assembly 300 and the screen of the electronic device 200. Figure 6 As shown, the end of the limiting platform 4 near the side wall of the mounting groove 11 is connected to the side wall, and the bottom of the mounting groove 11 near the bottom 13 is connected to the bottom 13. The space between the two opposing limiting platforms 4 on the opposite side walls is used to place the protective film assembly 300; the upper end of the limiting platform 4 away from the bottom 13 is connected to the lower end of the positioning member 2, and the distance between the two opposing limiting platforms 4 on the two opposite side walls of the mounting groove 11 is less than the distance between the side of the elastic member 3 away from the clearance groove 14 and the opposite side wall.

[0072] During assembly, place the groove 12 of the mounting slot 11 of the film applicator 100 vertically upward, then place the protective film assembly 300 into the bottom 13 of the mounting slot 11, and then slide the electronic device 200 into the mounting slot 11 along the guide slope 322. When the side structure of the electronic device 200 contacts the upper end of the limiting platform 4, it indicates that the electronic device 200 is in place in the mounting slot 11. Turn the assembly of the film applicator 100 and the electronic device 200 over so that the groove 12 of the mounting slot 11 is vertically downward. At this time, under the action of gravity, a gap is maintained between the screen of the electronic device 200 and the upper end of the limiting platform 4. Press the protective film assembly 300 in the film applicator 100 to contact the screen of the electronic device 200, thereby applying the film to the electronic device 200.

[0073] like Figure 1 As shown, a window 1515 is provided on the bottom 13 of the mounting base 1, which is opposite to the slot 12. The protective film assembly 300 of the bottom 13 is pressed against the screen of the electronic device 200 through the window 1515, so that the protective film assembly 300 and the screen are in contact. At the same time, the window 1515 is used to observe whether there are air bubbles between the screen and the protective film assembly 300.

[0074] The protective film assembly 300 includes a first separation layer, a protective layer, and a second separation layer; the first and second separation layers are respectively disposed on both sides of the protective layer and are adhered to the protective layer. When applying the film using the film applicator 100 provided by this utility model, the protective film assembly 300 is first placed in the bottom 13 of the mounting groove 11, with the second separation layer adhering to the bottom 13. A fixing hole is provided at one end of the second separation layer, such as... Figure 1 As shown, a film fixing member 16 is provided at one end of the mounting base 1 along its length. When the protective film assembly 300 is installed into the mounting groove 11, the film fixing member 16 passes through the fixing hole to fix the protective film assembly 300 and prevent the protective film assembly 300 from moving along the length of the mounting groove 11. Meanwhile, as... Figure 8 and Figure 10 As shown, the protective film assembly 300 is placed between the symmetrical limiting platforms 4 on both sides of the width direction of the mounting groove 11, and the corresponding limiting platforms 4 fix the protective film assembly 300 in the width direction.

[0075] After placing the protective film assembly 300 and the mounting base 1, the first separation layer and the protective layer are separated by a pull strap at one end of the first separation layer, exposing the side of the protective layer that contacts the screen of the electronic device 200. The electronic device 200 is then placed into the mounting groove 11. When the side structure of the electronic device 200 is aligned with the upper end of the limiting platform 4, the electronic device 200 is properly positioned within the mounting groove 11. At this point, the entire assembly of the film applicator 100 and the electronic device 200 is flipped over. The second separation layer is touched and pressed from the opening 1515, causing the middle area of ​​the protective layer to first adhere to the middle position of the screen of the electronic device 200. Then, the protective layer and the screen gradually adhere towards both ends along the length direction, preventing residual air between the protective layer and the screen and improving the film application effect of the film applicator 100. After the protective layer and the screen of the electronic device 200 are adhered, the mounting base 1 and the electronic device 200 are separated. By separating the second separation layer and the protective layer, the film application on the screen of the electronic device 200 is completed. The film applicator 100 can quickly apply film to electronic devices 200 of different sizes. By setting the window 1515 on the mounting base 1, the generation of bubbles in the protective layer and screen can be reduced, improving the film application effect and ensuring excellent film application quality.
