Description

Technical Field

[0001] The utility model relates to the technical field of film sticking, in particular to a film sticking device. Background Art

[0002] Mobile phones and other electronic devices have become indispensable communication tools in people's lives. Frequent use of mobile phones can easily cause screens to become dirty or even scratched. Screens are typically protected by applying screen protectors (e.g., tempered glass screen protectors). However, when applying screen protectors, most people rely on their experience to determine whether the screen protectors are applied flatly and completely cover the screen. This can easily cause the screen protectors to be applied crookedly, require multiple adjustments, or generate numerous bubbles that cannot be completely eliminated, causing significant trouble for the operator.

[0003] The film-applying auxiliary device (also called film applicator) currently on the market can, after the main body of the film applicator is put on the mobile phone, make the film-applying area of ​​the mobile phone screen consistent with the limit area of ​​the film applicator. When applying the film, as long as one end is aligned, no additional manual operation is required to adjust the position of the tempered glass film relative to the mobile phone screen, the purpose of pre-positioning can be achieved, and the film can be accurately aligned in one go, reducing the chance of crooked application and thereby reducing the difficulty of film application. Then, the self-adhesive properties of the tempered glass film are used to achieve automatic fitting and exhaust, so that the tempered glass film can be gradually and completely applied to the mobile phone screen.

[0004] However, due to the structural limitations of existing film applicators, when used with mobile phones, the internal control size is usually too large. When applying the film, if the upper part is applied off-center, there is a probability that the lower part will overlap, making it difficult to control the position of the tempered film. Utility Model Content

[0005] The embodiment of the utility model provides a film applicator, which can prevent the lower half of the film from overlapping when applying the film, and facilitates the control of the lowering position of the tempered film.

[0006] The utility model discloses a film applicator, comprising: a limiting frame, wherein the limiting frame is formed with a receiving groove for covering an electronic device, and a limiting window that passes through the receiving groove, so that the electronic device is clamped in the receiving groove, and the screen of the electronic device corresponds to the limiting window; the top of the limiting window is provided with long side positioning protrusions in pairs, and the opposite sides of the width direction of the limiting window are provided with short side positioning protrusions, the long side positioning protrusions are used to position the tempered film in the length direction, and the short side positioning protrusions are used to position the tempered film in the width direction; the limiting frame has an avoidance area on a side away from the long side positioning protrusion, so that the tail of the limiting window is flush with the plane where the screen of the electronic device is located or the tail of the limiting window is lower than the plane where the screen of the electronic device is located.

[0007] Optionally, the limiting frame includes a limiting bar corresponding to the screen of the electronic device, and a barrier corresponding to the main body of the electronic device; the limiting window is formed at the limiting bar, and the accommodating groove is formed at the barrier.

[0008] Optionally, the long side positioning protrusion includes a long side positioning segment, an arc segment and a short side positioning segment connected in sequence on the inner side of the limiting strip, the long side positioning segment corresponds to the top of the limiting window, and the short side positioning segment corresponds to one side of the limiting window in the width direction.

[0009] Optionally, the short-side positioning protrusion is in the shape of an elongated strip, and an inner edge of the short-side positioning protrusion corresponding to one side of the limiting window and an inner edge of the short-side positioning segment are on the same plane.

[0010] Optionally, the short side positioning protrusion is adjacent to the avoidance area, and the limiting strip includes a connecting section, a transition section and an avoidance section that are interconnected, and the transition section and the connecting section correspond to the avoidance area.

[0011] Optionally, a hand buckle portion is provided on the limit bar.

[0012] Optionally, the inner circle of the enclosure is provided with reinforcing ribs at intervals, and the reinforcing ribs are provided along the depth direction of the accommodating groove.

[0013] Optionally, the film applicator is integrally injection molded.

[0014] Optionally, the enclosure has a pressing portion corresponding to the power button of the electronic device.

[0015] Optionally, the enclosure further comprises a relief portion for avoiding a volume button of the electronic device.

[0016] Compared with the prior art, the beneficial effect of the film applicator provided by the embodiment of the present invention is that: when the film applicator cooperates with the electronic device through the limiting frame, the accommodating groove formed by the limiting frame is clamped with the outer ring of the electronic device, so that the phase position relationship between the limiting frame and the electronic device is maintained stable. At the same time, the limiting window formed by the limiting frame corresponds to the screen of the electronic device to limit the area of ​​the screen of the electronic device where the film needs to be applied. In this way, when applying the film, the long side positioning protrusions arranged in pairs at the top of the limiting window can be used as a reference for applying the tempered film. It is only necessary to first align one side of the length direction of the tempered film with the two long side positioning protrusions to ensure the accuracy of the position during the film application process, thereby reducing the probability of the patch overlapping the film due to the skew of the tempered film during the film application process. In addition, by providing short side positioning protrusions on opposite sides of the width direction of the limiting window, the tempered film can be guided and limited during the film application process to ensure that the tempered film is aligned with the screen of the electronic device. It is understandable that during the film application process, if one side of the tempered film in the length direction is not aligned well with the two long-side positioning protrusions, there may be a certain angle of deviation. This small angle of deviation will be magnified as the length direction extends, causing the other side of the tempered film to be skewed to a certain extent. In this embodiment, an avoidance area is set on the side of the limit frame away from the long-side positioning protrusion. This avoidance area makes the tail of the limit window flush with the plane of the electronic device screen or the tail of the limit window lower than the plane of the electronic device screen. This can avoid the tempered film from overlapping, thereby ensuring a stable fit between the tempered film and the screen of the electronic device and avoiding the generation of bubbles. By adopting the above method, during the film application process, it is possible to avoid the lower half of the film from overlapping, making it convenient to control the lowering position of the tempered film.

[0025] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0026] like Figure 1 and Figure 4 As shown, an embodiment of the present invention provides a film applicator 100, comprising: a limiting frame 110, the limiting frame 110 is formed with a receiving groove for covering the electronic device 105, and a limiting window that passes through the receiving groove, so that the electronic device 105 is clamped in the receiving groove, and the screen of the electronic device 105 corresponds to the limiting window; long side positioning protrusions 120 are arranged in pairs at the top of the limiting window, and short side positioning protrusions 130 are arranged on opposite sides in the width direction of the limiting window, the long side positioning protrusions 120 are used to position the tempered film in the length direction, and the short side positioning protrusions 130 are used to position the tempered film in the width direction; the limiting frame 110 has an avoidance area 116 on the side away from the long side positioning protrusion 120, so that the tail of the limiting window is flush with the plane where the screen of the electronic device 105 is located or the tail of the limiting window is lower than the plane where the screen of the electronic device 105 is located.

[0027] Specifically, through the accommodating groove formed on the limiting frame 110 and the limiting window that extends through the accommodating groove, when the film applicator 100 is mated with the electronic device 105, the accommodating groove and the outer ring of the electronic device 105 are aligned and limited, so that the limiting frame 110 maintains a stable position relative to the electronic device 105, avoiding displacement during use. After the limiting frame 110 and the electronic device 105 are relatively fixed, the limiting window corresponds to the screen of the electronic device 105, thereby limiting the position of the tempered glass film when applying it to the screen of the electronic device 105.

[0028] By setting the long side positioning protrusions 120 in pairs at the top of the limit window, when the tempered film is applied, one side of the tempered film in the length direction can be abutted against the long side positioning protrusions 120, and the side edge of the tempered film in the length direction can be positioned accordingly. It can be understood that by setting the long side positioning protrusions 120 in pairs, one side edge of the tempered film in the length direction needs to be abutted against the two long side positioning protrusions 120 respectively to avoid the tempered film from being skewed, which is beneficial to avoid the film overlapping phenomenon during the film application process.

[0029] In addition, by providing an avoidance area 116 on the side of the positioning frame away from the long-side positioning protrusions 120, during the film application process, if the alignment between one side of the tempered film in the longitudinal direction and the two long-side positioning protrusions 120 is not very high, resulting in a slight deviation of the tempered film, the avoidance area 116 can avoid the tempered film, and the tempered film can be highly adhered to the screen of the electronic device 105 during the film application process, avoiding the influence of the film applicator 100 and not affecting the final film application effect. The electronic device 105 can be a mobile phone or a tablet computer.

[0030] The film applicator 100 provided in the embodiment of the present application, when the film applicator 100 is matched with the electronic device 105 through the limiting frame 110, the accommodating groove formed by the limiting frame 110 is clamped with the outer ring of the electronic device 105, so as to maintain the stability of the phase position relationship between the limiting frame 110 and the electronic device 105. At the same time, the limiting window formed by the limiting frame 110 corresponds to the screen of the electronic device 105 to limit the area of ​​the screen of the electronic device 105 where the film needs to be applied. In this way, when applying the film, the long side positioning protrusions 120 arranged in pairs at the top of the limiting window can be used as a reference for applying the tempered film. It is only necessary to first align one side of the tempered film in the length direction with the two long side positioning protrusions 120 to ensure the accuracy of the position during the film application process, thereby reducing the probability of the patch overlapping the film due to the skew of the tempered film during the film application process. In addition, by providing short-side positioning protrusions 130 on opposite sides of the limiting window in the width direction, the tempered film can be guided and limited during the film application process, ensuring that the tempered film is aligned with the screen of the electronic device 105. It is understandable that during the film application process, if one side of the tempered film in the length direction is not aligned and fitted with the two long-side positioning protrusions 120 sufficiently, there may be a certain angle of deviation. This slight angle of deviation will be magnified as it extends in the length direction, causing the other side of the tempered film to be skewed to a certain extent. In this embodiment, by providing an avoidance area 116 on the side of the limiting frame 110 away from the long-side positioning protrusions 120, the avoidance area 116 makes the tail of the limiting window flush with the plane of the electronic device 105 screen or lower than the plane of the electronic device 105 screen, which can prevent the tempered film from overlapping, thereby ensuring a stable fit between the tempered film and the screen of the electronic device 105 and avoiding the generation of bubbles. By adopting the above method, during the film application process, it is possible to avoid overlapping of the lower half of the film, making it easier to control the lowering position of the tempered film.

[0031] like Figure 1 As shown, the limit frame 110 includes a limit bar 112 corresponding to the screen of the electronic device 105 and a barrier 114 corresponding to the main body of the electronic device 105 ; the limit window is formed at the limit bar 112 , and the accommodating groove is formed at the barrier 114 .

[0032] Specifically, the plane of the limiting strip 112 is perpendicular to the annular surface of the enclosure 114, and the limiting strip 112 extends to both the inner and outer rings of the enclosure 114. The inner ring forms the aforementioned limiting window, and the outer ring forms a reinforcement structure, which helps to enhance the structural strength of the limiting frame 110 and prevents tearing under stress. During use, the enclosure 114 only needs to be placed over the outer ring of the electronic device 105 to ensure the stability of the relative position. After the electronic device 105 is restrained in the receiving slot, the limiting window corresponds to the screen of the electronic device 105.

[0033] like Figure 1 and Figure 2As shown, the long side positioning protrusion 120 includes a long side positioning segment 122, an arc segment 124 and a short side positioning segment 126 connected in sequence on the inner side of the limiting strip 112. The long side positioning segment 122 corresponds to the top of the limiting window, and the short side positioning segment 126 corresponds to one side in the width direction of the limiting window.

[0034] Specifically, by setting the long side positioning protrusion 120 to be a long side positioning segment 122, an arc segment 124 and a short side positioning segment 126 connected in sequence, in actual application, the long side positioning segment 122 corresponds to the top of the limit window, and is used to correspond to one side of the length direction of the tempered film, and the short side positioning segment 126 corresponds to one side of the width direction of the limit window, and is used to correspond to one side of the width direction of the tempered film, thereby ensuring the accuracy of the centering of the film. During the film application process, the tempered film and the screen are at a certain angle to the long side positioning segment 122 to position one side of the length direction of the tempered film. After the positioning is completed, the tempered film and the screen are attached together, and the above angle gradually becomes smaller. At this time, the tempered film first corresponds to the short side positioning segment 126 to correct the tempered film, further reducing the chance of the tempered film being attached sideways. After the tempered film and the screen are completely attached, it can be ensured that the two are completely aligned, avoiding the phenomenon of overlapping films during film application.

[0035] like Figure 2 As shown, the short side positioning protrusion 130 is in the shape of an elongated strip, and the inner edge of the short side positioning protrusion 130 corresponding to one side of the limiting window is on the same plane as the inner edge of the short side positioning segment 126 .

[0036] Specifically, the short-side positioning protrusions 130 correspond to the width of the tempered film and work in conjunction with the long-side positioning protrusions 120 to limit the tempered film. Furthermore, the inner edge of the short-side positioning protrusion 130 corresponding to one side of the limiting window is coplanar with the inner edge of the short-side positioning segment 126. This helps ensure that the side surfaces of the tempered film in the width direction are aligned with the short-side positioning segment 126 and the short-side positioning protrusions 130, respectively, to guide and limit the tempered film.

[0037] like Figure 1 and Figure 3 As shown, the short side positioning protrusion 130 is adjacent to the avoidance area 116 , and the limiting strip 112 includes a connecting section 1122 , a transition section 1124 and an avoidance section 1126 that are interconnected, and the transition section 1124 and the connecting section 1122 correspond to the avoidance area 116 .

[0038] Specifically, the short side positioning protrusion 130 is preferably set in the middle of the length direction of the limit frame 110 to guide and limit the tempered film, and avoid being set in the avoidance area 116. The avoidance area 116 is the position where the tempered film is freely lowered after the relative position relationship between the tempered film and the screen of the electronic device 105 is basically clear, and the overlap with the tempered film should be avoided as much as possible. For example, the short side positioning protrusion 130 can be set at the connecting section 1122, and the transition section 1124 is to make a smooth transition between the connecting section 1122 and the avoidance section 1126 to ensure the overall smoothness of the limit frame 110. The transition section 1124 has a certain inclination angle, and the avoidance section 1126 avoids protruding from the screen of the electronic device 105 to ensure the desired film effect.

[0039] like Figure 1 As shown, a hand buckle portion 140 is provided on the limiting strip 112 .

[0040] By adopting the above method, after the film is applied, it is convenient to tear the film applicator 100 off the electronic device 105 by simply pinching the buckle portion with your hand, and applying hand force to the film applicator 100 to reduce the difficulty of operation.

[0041] like Figure 4 and Figure 5 As shown, the inner circle of the enclosure 114 is provided with reinforcing ribs 1142 at intervals, and the reinforcing ribs 1142 are provided along the depth direction of the accommodating groove.

[0042] Specifically, when the enclosure 114 is matched with the electronic device 105, in order to reduce the deformation rate of the enclosure 114 and improve the structural strength of the enclosure 114, reinforcing ribs 1142 can be set on the inner circle of the enclosure 114. The reinforcing ribs 1142 are set along the depth direction of the accommodating groove. While strengthening its own structure, it can also play a guiding role, reducing the difficulty of being put on the electronic device 105, and enabling the enclosure 114 and the electronic device 105 to fit closely, avoiding accidental loosening, which is conducive to ensuring the stability of mutual cooperation.

[0043] In an optional embodiment of the present application, the film applicator 100 is integrally injection molded.

[0044] Specifically, the film applicator 100 is injection molded using a front film drafting method, which helps ensure that the internal control design value is consistent with the actual use value, thereby improving the accuracy of film application. The film applicator 100 is injection molded in one piece to ensure molding consistency, thereby ensuring the accuracy of the fit. In addition, the film applicator 100 manufactured in one piece provides better structural strength and appearance, and helps reduce production costs.

[0045] like Figure 3 and Figure 5As shown, the enclosure 114 has a pressing portion 1144 corresponding to the power button of the electronic device 105.

[0046] Specifically, there is a gap between the pressing portion 1144 and the enclosure 114, so that the pressing portion 1144 can be pressed more conveniently. After the film is applied, the pressing portion 1144 can be pressed to trigger the power button of the electronic device 105, which is convenient for observation after the film is applied to ensure the quality of the film.

[0047] like Figure 5 As shown, the enclosure 114 also has a avoidance portion 1146 for avoiding the volume button of the electronic device 105.

[0048] Specifically, by providing an avoidance portion 1146 on the enclosure 114, the volume button protruding from the outer circle of the electronic device 105 can be avoided, ensuring stable cooperation between the enclosure 114 and the electronic device 105, which is conducive to ensuring good cooperation between the limit frame 110 and the electronic device 105 and improving stability during film application.
