Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories technology, and in particular to a film application device and film application assembly. Background Technology

[0002] Mobile phones, tablets, and other electronic devices have gradually become indispensable items in people's daily lives. Taking mobile phones as an example, due to the high frequency of use, screen scratches often occur. To prevent this, people apply a protective film to the screen. To improve the application effect, a screen protector applicator is usually used.

[0003] Existing screen protector applicators typically have a sliding pressure element that presses and releases air to help the screen protector adhere to the screen. When the pressure element slides back and applies the screen protector for the first time, it will re-contact the screen protector when it returns to its original position. Because the pressure element is tightly fitted to the screen, it can easily peel the screen protector off at the edge, affecting the application result. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a film-applying device in which the film-pressing component remains pressed against the protective film when it slides to the end position of the film pressing, so as to avoid the protective film being lifted when it is pulled back.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A film-applying device includes a base with a recessed receiving groove on its upper surface for placing an electronic device, and slide rails on both sides of the base; and a film-pressing module that slides along the slide rails in the sliding direction. The film-pressing module has a film-pressing member located on one side of the upper surface of the base, used to press a protective film between the film-pressing member and the electronic device onto the electronic device. The base includes a first base and a second base located on opposite sides of the receiving groove along the sliding direction. The sliding position of the film-pressing module includes a starting position and an ending position. The starting position is located on the side of the receiving groove closer to the first base, and the ending position is located on the side of the receiving groove closer to the second base. When the film-pressing module slides to the ending position, the film-pressing member at least partially presses against the protective film, and at least part of its projection along the depth direction of the receiving groove is located on the second base.

[0007] In one embodiment of the present invention, along the sliding direction, the slide rail has an extension portion extending toward the second base to receive the groove; when the pressing module slides to the end position, the maximum distance between the side of the pressing member near the second base and the end position is L, and the length dimension of the extension portion along the sliding direction is less than the maximum distance L.

[0008] In one embodiment of this utility model, the two ends of the pressing member in the length direction extend beyond the opposite side walls of the receiving groove, and the two ends of the pressing member in the length direction are a first fixed end and a second fixed end, respectively; the pressing module also includes a fixing member, the fixing member is provided with a slider, the slider is slidably engaged with the slide rail, and the angle between the length direction of the pressing member and the sliding direction is greater than 0° and less than 90°.

[0009] In one embodiment of the present invention, the first fixed end is located on the side away from the second base relative to the second fixed end, and the distance between the first fixed end and the edge of the receiving groove near the second base is less than one-fifteenth of the length dimension of the receiving groove along the sliding direction.

[0010] In one embodiment of the present invention, the pressing member includes a roller and a rotating shaft passing through the roller, wherein the two ends of the roller in the length direction extend beyond the opposite side walls of the receiving groove.

[0011] In one embodiment of this utility model, the two ends of the rotation shaft along the length direction are the first fixed end and the second fixed end, respectively, and the first fixed end and the second fixed end are rotatably disposed on the fixing member; when the pressing module slides to the end position, the projection of the roller along the depth direction of the receiving groove is at least partially located in the receiving groove, and at least partially located at the second base.

[0012] In one embodiment of the present invention, the protective film has four rectangular corners. When the pressing module slides to the end position, the pressing member presses at least partially against two adjacent sides of one corner of the protective film near the second base.

[0013] In one embodiment of the present invention, the pressing member has two opposite sides along the sliding direction and a contact surface located between the two sides, the contact surface facing the receiving groove, and the side near the first base is connected to the contact surface by a guide slope, the guide slope forming an angle greater than 0° and less than 90° with the protective film.

[0014] In one embodiment of the present invention, when the pressing module slides to the starting position, the projection of the pressing member along the depth direction of the receiving groove is located within the first base.

[0015] This utility model also provides a film application assembly, including any of the film application devices described above, and a protective film assembly disposed between the base and the pressing member. The protective film assembly includes a protective film and a positioning film. The positioning film is detachably fixed to the base. The protective film is located on the side of the positioning film near the receiving groove. The orthographic projection of the protective film along the depth direction of the receiving groove is located within the receiving groove.

[0016] The beneficial effects of this invention are as follows: Due to the fixed design of the pressing component at the end position, it effectively prevents the pressing component from sliding out of the receiving groove. The pressing component remains pressed against the protective film, avoiding interference between the phone and the pressing component when it is pulled back, allowing the pressing component to peel the film back up. Simultaneously, by setting the pressing component in the form of a roller, the roller applies only a vertical pressing force to the protective film during rolling, preventing the protective film from slipping during the bonding process due to excessive friction.

Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0031] Reference Figures 1-11 The present invention provides a film-applying device, which may specifically include, for example, a base 1 and a film-pressing module 2.

[0032] The base 1 is provided with a receiving groove 11, which is used to place electronic devices 4, such as mobile phones, tablets, etc. The shape and size of the receiving groove 11 can match the electronic devices 4, so that when the electronic devices 4 are placed in the receiving groove 11, they can be better fixed and will not move easily. The base 1 is provided with a positioning part for positioning the protective film assembly 3. The protective film assembly 3 is positioned on the base 1 and covers the electronic devices 4 in the receiving groove 11. The base 1 positions the electronic devices 4 and the protective film 31, so that the protective film 31 can be accurately attached to the screen of the electronic devices 4.

[0033] The base 1 is provided with a protective film assembly 3, which may include, for example, a protective film 31, a release film 33, a pull strip, and a positioning film 32. The release film 33 and the positioning film 32 are located on opposite sides of the protective film 31. The pull strip is located on the side of the release film 33 away from the protective film 31, and the release film 33 is located on the side closer to the receiving groove 11. The pull strip connects to the release film 33, and pulling the pull strip removes the release film 33. The positioning film 32 is located on the side of the protective film 31 away from the receiving groove 11. Both ends of the positioning film 32 are detachably fixed to the base 1 along its length, and the protective film 31 is pasted on the side of the positioning film 32 facing the receiving groove. The protective film 31 is located above the receiving groove 11, and its orthographic projection along the depth direction of the receiving groove 11 is within the range of the receiving groove 11. The shape and size of the protective film 31 may, for example, match the electronic device 4. The protective film 31 is suspended above the electronic device 4 by the positioning film 32 and is pasted onto the mobile phone screen by applying pressure.

[0034] The film pressing module 2 is positioned above the base 1 and slides on the base 1 to roll or squeeze the protective film 31, expelling air bubbles between the protective film 31 and the electronic device. The base 1 has slide rails 12 on both sides, and the film pressing module 2 slides back and forth on the base 1 in a sliding engagement with the slide rails 12, ensuring that the film pressing module 2 can move precisely along the predetermined trajectory of the slide rails 12 during operation. The film pressing module 2 has a film pressing component 22, located on the side of the film pressing module 2 facing the base 1. When the film pressing module 2 slides into the receiving groove 11, the film pressing component 22 can contact the protective film 31, thereby pressing the protective film 31 onto the electronic device 4.

[0035] Furthermore, the base 1 includes a first base 101 and a second base 102 located on opposite sides of the receiving groove 11 along the sliding direction, which increases the overall structure of the base 1 and enhances its stability. The two ends of the slide rail 12 extend from the first base 101 and the second base 102 respectively, ensuring that the slide rail 12 passes through the receiving groove 11. The sliding position of the pressing module 2 is limited by the slide rail 12, and the two ends of the slide rail 12 form the starting and ending positions of the pressing module 2.

[0036] The starting position is located on the side of the receiving groove 11 near the first base 101, and the ending position is located on the side of the receiving groove 11 near the second base 102, ensuring that the laminating module 2 can slide through the receiving groove 11. When the laminating module 2 slides to the starting position, the projection of the laminating member 22 along the depth direction of the receiving groove 11 is located within the first base 101. This ensures that there is sufficient space before laminating to align the electronic device 4 with the protective film 31, and then the laminating member 22 applies pressure to the protective film 31. At the same time, it ensures that the laminating member 22 can gradually apply pressure from the outer edge of the protective film 31 when the laminating operation begins, allowing the protective film 31 to transition more smoothly during the bonding process.

[0037] In another embodiment of the present invention for limiting the positioning of the film-pressing module 2, the base 1 is provided with a limiting part for limiting the positioning of the film-pressing module 2. The limiting part is provided on the second base 102. When the film-pressing module 2 slides to the end position, one side of the film-pressing module 2 abuts against the limiting part. Specifically, the limiting part extends in the direction away from the base 1 and along the depth direction of the receiving groove 11, the distance from the highest point of the limiting part to the bottom of the receiving groove 11 is greater than the distance from the film-pressing module 2 to the bottom of the receiving groove 11.

[0038] When the film-pressing module 2 slides from the starting position to the ending position, the film-pressing component 22 presses over the protective film 31. When the film-pressing module 2 slides to the ending position, the film-pressing component 22 is at least partially pressed onto the protective film 31, and at least part of its projection along the depth direction of the receiving groove 11 is located at the second base 102. Therefore, when the film-pressing module 2 is pulled back from the ending position to the starting position, it still maintains the pressing effect on the protective film 31, ensuring stability during the film application process and preventing the protective film 31 from being pulled up or shifting in position during the return. Furthermore, the fact that the film-pressing component 22 slides at least partially into the area of ​​the second base 102 ensures that the protective film 31 is completely pressed onto the surface of the electronic device 4, preventing the formation of air bubbles in the protective film 31.

[0039] Since the slide rail 12 restricts the starting position and the ending position of the film pressing module 2, in order to ensure the sliding range of the film pressing module 2, the starting position of the slide rail 12 is within the range of the first base 101 along the sliding direction, and the ending position can be set within the range of the receiving groove 11, so as to prevent the film pressing component 22 from sliding out of the protective film 31 when it slides to the key position, so that the protective film 31 will be lifted when the film pressing module 2 is pulled.

[0040] Preferably, the slide rail 12 has an extension 121 extending toward the second base 102 to form a receiving groove 11. The end point of the extension 121 extends beyond the receiving groove 11 along the length direction of the base 1 and is located within the range of the second base 1, ensuring that the pressing module 2 can slide through the receiving groove 11 and ensuring that the protective film 31 of the receiving groove 11 is rolled. To prevent the pressing member 22 from completely sliding out at the end position, when the pressing module 2 slides to the end position, the maximum distance between the pressing member 22 and the end position is L. The length dimension of the extension 121 along the sliding direction is less than the maximum distance L. Therefore, the pressing member 22 will not completely exceed the range of the receiving groove 11. And because the protective film 31 matches the size of the receiving groove 11, the pressing member 22 will not completely detach from the protective film 31 and will remain pressed onto the protective film 31. Furthermore, the minimum distance between the pressing member 22 and the end position is less than the length of the extension 121 along the sliding direction. Therefore, when the pressing module 2 is at the end position, at least part of the pressing member 22 will slide out of the range of the receiving groove 11. This part can vent the protective film 31 in the length direction, ensuring that at least part of it slides across the range of the protective film 31 in the length direction.

[0041] Since some of the pressing parts 22 need to be pressed against the protective film 31 at all times, in order for some of the pressing parts 22 to slide over the protective film 31 and ensure the air venting and bonding effect between the protective film 31 and the electronic device, the pressing parts 22 can be tilted relative to the sliding direction so that one end can slide over the length range of the protective film 31, while the other end remains unpressed on the protective film 31.

[0042] The two ends of the pressure film member 22 extend beyond the opposite side walls of the receiving groove 11 in the length direction, so as to ensure that when sliding through the protective film 31, it can cover the protective film 31 in the width direction, and then move along the length direction to vent it, so that it can pass through the entire range of the protective film 31.

[0043] Furthermore, the film pressing module 2 also includes a fixing member 21, which is used to fix the film pressing member 22 and is slidably connected to the base 1. The fixing member 21 is provided with a slider 23, which is engaged in sliding cooperation within the slide rail 12, restricting the movement of the fixing member 21 along the trajectory of the slide rail 12. The film pressing member 22 includes a first fixing end 221 and a second fixing end 222 located outside the receiving groove 11 along the width direction. The first fixing end 221 and the second fixing end 222 are connected to the fixing member 21 to fix the film pressing member 22 on the fixing member 21.

[0044] Along the sliding direction, the slider 23 is located on the side of the pressing member 22 closer to the second base 102. Therefore, the pressing member 22 is positioned so that the slider 23 is away from the second base 102, and the slider 23 is closer to the second base 102 relative to the pressing member 22. Preferably, the angle between the length direction of the pressing member 22 and the sliding direction is greater than 0° and less than 90°. The distance between the first fixed end 221 and the slider 23 is greater than the distance between the second fixed end 222 and the slider 23. The first fixed end 221 is located on the side away from the second base 102 relative to the second fixed end 222. Therefore, the pressing member 22 is inclined relative to the width direction of the base 1. Specifically, the base 1 has a length direction and a width direction, wherein the length direction and the width direction are arranged perpendicularly. The length direction of the pressing member 22 is not parallel to the width direction of the base 1, and an angle is formed between the length direction of the pressing member 22 and the width direction of the base 1. When the film pressing module 2 is at the end position, the second fixed end 222 is closer to the second base 102 than the first fixed end 221. The distance between the first fixed end 221 and the end position is greater than the length of the extension 121 on the slide rail 12. Therefore, the part of the film pressing component 22 that is close to the first fixed end 221 will always be pressed against the protective film 31.

[0045] The portion of the pressing member 22 near the first fixed end 221 presses against the protective film 31 without exceeding its area. However, to ensure the venting range of the pressing member and the effectiveness of the film application, the pressing member 22 should be as close as possible to the edge of the protective film 31 near the second base 102, which is also the edge of the receiving groove 11 near the second base 102. To ensure the sliding pressing range of the pressing member 22 on the protective film 31, the first fixed end 221 and the edge of the receiving groove 11 near the second base 102 are spaced apart. This distance is less than one-fifteenth of the length of the receiving groove 11, which is also less than one-fifteenth of the length of the protective film 31, so that the pressing member 22 presses over most of the area of ​​the protective film 31. Furthermore, the protective film 31 is fixed to the base 1 by the positioning film 32. The pressing component 22 presses the protective film 31 from the positioning film 32 onto the electronic device 4. When the pressing module 2 is at the end position, most of the protective film 31 falls off from the positioning film 32 and most of it adheres to the electronic screen. This can prevent the protective film 31 from remaining adhered to the electronic screen when the pressing component 22 returns to the starting position, and it will not be pulled back onto the positioning film 32.

[0046] The protective film 31 has four rectangular corners that match the screen of the electronic device 4. Since the pressing component 22 remains pressed against the protective film 31 at the end position, a portion of the protective film 31 near the second base 102 will not be pressed by the pressing component 22. To ensure that the pressing component 22 can press the protective film 31 as completely as possible, when the pressing module 2 slides to the end position, the pressing component 22 at least partially presses against two adjacent sides of the protective film 31 near the second base 102 and the first fixed end 221. This ensures that the pressing component 22 can press the protective film 31 as completely as possible, ensuring that the protective film 31 can adhere flatly and firmly to the screen, thus improving the screen's protective effect.

[0047] In a preferred embodiment of this utility model, the film pressing component 22 includes a roller and a rotating shaft passing through the roller. The two ends of the rotating shaft are a first fixed end 221 and a second fixed end 222 extending from the two ends of the roller. The first fixed end 221 and the second fixed end 222 are rotatably mounted on the fixing component 21, and the roller rotates with the rotating shaft. The length of the roller is greater than the width of the receiving groove 11, and the two ends of the roller extend beyond the opposite side walls of the receiving groove 11, ensuring that the roller can completely cover the entire width of the film when rolling. This ensures that the protective film 31 is evenly pressed onto the surface of the electronic device with each slide of the roller, ensuring complete adhesion.

[0048] Furthermore, during the movement of the film pressing module 2, the rollers rolling on the protective film 31 reduce the impact of friction, preventing the protective film 31 from slipping during the bonding process due to excessive friction. The rollers apply only a vertical pressing force to the protective film 31 during rolling, ensuring smooth contact between the protective film 31 and the equipment surface, thus preventing deformation or breakage of the protective film 31 due to lateral pulling.

[0049] When the film pressing module 2 slides to the end position, the roller's projection along the depth direction of the receiving groove 11 is at least partially located within the receiving groove 11 and at least partially located at the second base 102. During the retraction process of the film pressing module 2, the roller can maintain stable contact with the protective film 31, preventing the edge of the protective film 31 from lifting due to the movement of the roller. Furthermore, the continuous contact of the roller at the end position further prevents local gaps or air bubbles from forming in the protective film 31 due to a sudden reduction in pressure, thus improving the final bonding quality.

[0050] The pressing member 22 includes two sides and a contact surface between the two sides. The contact surface is located on the side of the pressing member 22 facing the receiving groove 11 and is in contact with the protective film 31. An inlet ramp is provided between the side near the first base 101 and the contact surface. When the pressing member 22 is pulled back at the end position, the inlet ramp enters the film range before the contact surface.

[0051] The guide slope is inclined relative to the contact surface, specifically manifested as a chamfer between the side and the contact surface. Therefore, the guide slope forms an angle greater than 0° and less than 90° with the side of the protective film 31 near the first base 101. When the pressing member 22 is pulled back, it is guided by the guide slope to smoothly transition into the protective film 31, avoiding direct friction and compression between the edge of the protective film 31 and the pressing member 22.

[0052] This invention, by setting the endpoint position of the sliding film pressing module 2, ensures that the film pressing component 22 remains pressed against the protective film 31 at the endpoint position, preventing it from slipping out of the protective film 31 and thus lifting the bonded protective film 31 during pullback. Simultaneously, by configuring the film pressing component 22 as a roller, the roller applies only a vertical pressing force to the protective film 31 during rolling, preventing slippage of the protective film during bonding due to excessive friction.

[0053] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
