Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment accessories, in particular to a roller-type film sticking device. Background Art

[0002] At present, electronic devices have become an indispensable communication tool in people's lives. However, due to the frequent use of electronic devices, the screens of electronic devices are easily dirty or even scratched. Generally, electronic device screens are protected by applying films to electronic devices. However, when applying tempered glass films, most of them are judged based on the experience of operators to determine whether the tempered glass films are applied flat and whether they completely cover the screen of the electronic device. Such operation can easily cause the tempered glass films to be applied crookedly, or require multiple adjustments, or generate more bubbles and cannot eliminate all bubbles, causing great trouble to the operators.

[0003] Tempered glass film has a self-adhesive property, which is mainly reflected in that when a part of the tempered glass film is bonded to the screen of an electronic device, even without applying external force, the bonding area will continue to expand outward by its own gravity until it is fully bonded.

[0004] A traditional film applicator is provided with a placement slot for placing the electronic device to be film-applied and a roller mechanism. During the film-applying process, the roller slides from the end of the placement slot to the bottom. During this process, due to the height difference between the screen of the electronic device in the placement slot and the top surface of the top of the placement slot, when the roller transitions from the top surface of the top of the placement slot to the screen of the electronic device in the placement slot, the position where the roller contacts the screen of the electronic device is not the edge of the screen, so that the position squeezed by the roller does not start from the edge of the screen, resulting in the edge of the electronic device not being squeezed, and a white edge phenomenon is easily generated, etc. Summary of the invention

[0015] The first bending part and the second bending part are both slidably connected to the slide rail via a slider, the slider is slidably installed in the slide rail, and the slider is integrally arranged at positions corresponding to the slide rail on the first bending part and the second bending part.

[0016] Furthermore, the slide rail is provided with a disassembly opening corresponding to the first bending portion and the second bending portion.

[0017] Furthermore, the placement groove is a lower groove structure in the positioning box body, and a plurality of pads and elastic strips are arranged in the placement groove.

[0020] Furthermore, the film applicator also includes a packaging box for accommodating the positioning box body.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] 1. The utility model provides an elastic pad on the positioning box body, and integrally connects one end of the elastic pad to the positioning box body to form an elastic pad with a certain elasticity. When the elastic pad is subjected to a downward pressure during the film application process, an upward restoring force is generated. When the roller assembly is used, the roller assembly slides to make the protective film in the film application assembly and the electronic device screen more closely fit. During the application process, the roller assembly is used to press the film application assembly so that the film application assembly and the electronic device screen fit together. Since the elastic pad generates an upward restoring force on the film application assembly, the roller assembly is used to move the elastic pad from the elastic pad to the electronic device screen. When the protective film slides toward the other end of the positioning box body, the protective film will first fit with the side of the electronic device screen close to the elastic pad. When the side of the electronic device screen close to the elastic pad is in a tightly fitted state, the protective film is further slid from one end of the electronic device to the other end through the roller assembly, which can effectively improve the degree of fitting of the protective film. Since the first fitting part of the protective film and the electronic device screen is the edge of the electronic device screen close to the elastic pad, it can be ensured that other parts of the subsequent electronic device screen are rolled and compacted by the roller assembly, so that the protective film and the electronic device screen can be more tightly and quickly fitted, and white edges and bubbles can be effectively prevented.

[0023] 2. The utility model arranges a first positioning piece on the convex block of the elastic pad to fix the film assembly, and cooperates with a second positioning piece slightly higher than the convex block to jointly install and fix the film assembly, and keeps the film assembly at a certain tilt angle in the horizontal direction, with the lowest tilt point located on the elastic pad, so as to ensure that the end close to the elastic pad is firstly attached to the electronic device screen, and the mutual cooperation between the elastic pad and the roller assembly can be further utilized to quickly and tightly adhere the electronic device screen;

[0024] In summary, the utility model solves the problem that in the traditional film applicator, when the roller transitions from the top surface of the top of the placement groove to the screen of the electronic device in the placement groove, the position where the roller contacts the screen of the electronic device is not the edge of the screen, so that the position squeezed by the roller does not start from the edge of the screen, resulting in the edge of the electronic device not being squeezed and the white edge phenomenon being easily generated.

[0031] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example 1

[0033] like Figure 1-3As shown, a roller-type film applicator includes a positioning box body 1, on which a placement groove 2 and a roller assembly 7 slidably arranged on the positioning box body 1 are provided, wherein the positioning box body 1 is provided with an elastic pad 4 for allowing the roller assembly 7 to transition from the positioning box body 1 to the electronic device screen in the placement groove 2, and the elastic pad can be raised and lowered.

[0034] In this embodiment, by providing an elastic pad 4 on the positioning box body 1 and cooperating with a roller assembly 7, when applying film to the electronic device, the roller assembly 7 can slide to make the protective film 33 in the film assembly 3 fit more closely to the electronic device screen. During the pasting process, the roller assembly 7 is used to press the film assembly 3 so that the film assembly 3 fits the electronic device screen. Since the elastic pad 4 will generate an upward restoring force on the film assembly 3, when the roller assembly 7 is used to slide from the elastic pad 4 to the other end of the positioning box body 1, the protective film 33 will first fit with the side of the electronic device screen close to the elastic pad 4. When the side of the electronic device screen close to the elastic pad 4 is in a tightly fitted state, the protective film 33 is further slid from one end of the electronic device to the other end through the roller assembly 7.

[0035] Furthermore, the elastic pad 4 is an extension plate extending from a side wall of the receiving groove 18 away from the placement groove 2 to another side wall close to the placement groove 2 , and a protrusion 6 is provided on one end of the elastic pad 4 close to the placement groove 2 .

[0036] Furthermore, a plurality of first positioning members 8 are provided on the protrusion 6, and the protrusion 6 is integrally provided on the elastic pad 4;

[0037] A fixing handle 10 is integrally provided at one end of the positioning box body 1. In the process of applying film to the electronic device, since the sliding roller assembly 7 is required for applying film, the positioning box body 1 is fixed by means of the fixing handle 10 to prevent the positioning box body 1 from moving during the sliding roller assembly 7, thereby affecting the quality of film application. A second positioning member 9 is provided on the top surface of the end of the positioning box body 1 away from the fixing handle 10. The first positioning member 8 and the second positioning member 9 together form a positioning and installation structure for installing the film application assembly 3. The height of the protrusion 6 in the vertical direction is the same as or lower than the height of the second positioning member 9. The first positioning member 8 on the protrusion 6 can fix the film application assembly 3 firmly and play a role in positioning the film application assembly 3 at the same time, thereby preventing the film application assembly 3 from being skewed and tilted during the film application process, thereby causing inaccurate film application.

[0038] The height difference between the protrusion 6 and the second positioning member 9 can directly affect the horizontal placement angle of the film assembly 3. When the horizontal placement angle of the film assembly 3 is inclined and the height of the second positioning member 9 is slightly higher than the protrusion 6, the roller assembly 7 can first fit the edge of the protective film 33 to the edge of the electronic device screen when the electronic device begins to be filmed, thereby further improving the fit between the screen and the protective film 33 and preventing white edges or bubbles from appearing at the fitting position between the edge of the electronic screen and the protective film 33.

[0039] Furthermore, slide rails 5 are respectively provided on both sides of the positioning box body 1, and the roller assembly 7 is detachably connected to the slide rails 5;

[0040] The side of the elastic pad 4 that fits with the edge of the electronic device is provided with a convex strip 15; since during the film application process, one side edge surface of the electronic device will fit with one side of the elastic pad 4, the elastic pad 4 will move up and down during the film application process, thereby easily rubbing the edge surface of the electronic device over a large area. By providing the convex strip 15, the friction area between the elastic pad 4 and the edge surface of the electronic device is greatly reduced, and large-area friction between the electronic device and the elastic pad 4 can be avoided during film application, while further fixing the electronic device.

[0041] Furthermore, the roller-type film applicator also includes a film applicator assembly 3, which includes a positioning film 31, a pull-out film 32 and a protective film 33.

Setting the film pressing roller 72 as a variable diameter columnar structure can make the film pressing roller 72 fit more closely and more closely to electronic devices with curved screen edges.

[0043] The first bending portion 74 and the second bending portion 75 are both slidably connected to the slide rail 5 via a slider, the slider is slidably installed in the slide rail 5, and the slider is integrally arranged at positions corresponding to the slide rail 5 on the first bending portion 74 and the second bending portion 75.

[0044] Furthermore, a disassembly opening 51 corresponding to the first bending portion 74 and the second bending portion 75 is provided on the slide rail 5; by providing the disassembly opening 51 on the slide rail 5, when the slider slides to a position aligned with the disassembly opening 51, the sliding frame 71 can be lifted upwards to remove the roller assembly 7 from the slide rail 5, and during the disassembly process, the alignment of the slider and the disassembly opening 51 can be observed through the observation opening 73.

[0045] Furthermore, the placement groove 2 is a lower groove structure in the positioning box body 1, and a plurality of pads 11 and elastic strips 12 are arranged in the placement groove 2. A avoidance opening 13 is reserved on the placement groove 2 to prevent conflict with the camera assembly of the electronic device. The pad 11 is fixedly installed at the bottom of the placement groove 2, and the elastic strip 12 is bonded to the inner walls on both sides of the placement groove 2 and the inner wall at one end away from the elastic pad 4; by arranging the elastic strip 12 in the placement groove 2, the compression and rebound characteristics of the elastic strip 12 can be utilized, and a plurality of elastic strips 12 arranged on the inner wall of the placement groove 2 are composed of an elastic frame for adapting to electronic devices of various sizes, thereby improving the adaptation range of the placement groove 2.

[0046] Furthermore, the second positioning member 9 is a variable diameter columnar structure, the upper part of which is a columnar structure with a smaller diameter. The diameter of the second positioning hole 35 is consistent with the diameter of the upper part of the second positioning member 9. The second positioning hole 35 is sleeved on the upper part of the second positioning member 9 and supported by the lower part of the second positioning member 9 with a larger diameter. The second positioning member 9 is used to connect with the second positioning hole 35 to position the film assembly 3.

[0047] Furthermore, the positioning box body 1 is externally connected to a flap 16 for covering the placement slot 2 of the positioning box body 1, and the film applicator also includes a packaging box 17 for accommodating the positioning box body 1; the flap 16 includes three parts that are interconnected and have creases between each other, and the three parts of the flap 16 can be folded in half to form a rectangular shell and wrap the positioning box body 1, one part of which is pasted on the bottom of the positioning box body 1, and the other part can be flipped over to cover one side and the top surface of the positioning box body 1, the area of ​​the part pasted on the bottom of the positioning box body 1 is consistent with the area of ​​the part covering the top of the positioning box body 1, and the flap 16 can be used as a protective cover of the positioning box body 1, and together with the packaging box 17 constitute the outer packaging structure of the product.
