Description

Technical field:

[0001] The utility model relates to the technical field of mobile phone film pasting, and in particular refers to a labor-saving inclined film pasting device, which reduces the magnitude of external force applied when pasting the film through a lever structure, thereby improving the convenience of film pasting. Background technology:

[0002] At present, mobile phone film applicators can be divided into scraper type, roller type and self-adhesive type according to the film application method. For the roller type film applicator, its working principle is: a pressure roller is provided on the film applicator. When in use, the protective film is adhered to the surface of the mobile phone screen through the relative movement between the pressure roller and the mobile phone positioning seat. In the process of rolling, the pressure roller gradually crushes and discharges the air between the protective film and the mobile phone screen, thereby achieving a perfect film application effect.

[0003] For the rolling film applicator, according to the different movement modes, it can be divided into the following two modes:

[0004] The first method is that the pressure roller is relatively stationary, and the positioning seat drives the mobile phone to move. For example, see the utility model patent with Chinese patent application number: 202223437428.1, which discloses a film sticking box and a film sticking assembly, and the technical solution adopted is: the inner shell (positioning seat) slides relative to the base, and the pressing part (pressure roller) installed on the base rolls the mobile phone protective film in the inner shell to complete the film sticking.

[0005] The second method is that the positioning seat is relatively stationary, and the user directly pushes the pressure roller to move. For example, the utility model patent with Chinese patent number: 202222793757.3 discloses a roller film laminating device with accurate laminating position. The technical solution adopted is: install a pressure roller on the sliding bracket, and by pushing the sliding bracket to move, the pressure roller rolls the protective film on the surface of the mobile phone to complete the film laminating.

[0006] For the second type of film applicator mentioned above, since the positioning seat is relatively stationary, the user needs to push the sliding bracket to drive the pressure roller to move relatively. During the movement of the sliding bracket, a certain pressing force must be maintained between the surface of the mobile phone and the pressure roller. In this case, the sliding bracket needs to apply a large pulling force to achieve smooth sliding. If the pressing force between the surface of the mobile phone and the pressure roller is insufficient, it is difficult to ensure perfect film application; while ensuring that the pressing force between the surface of the mobile phone and the pressure roller is sufficient, a large pulling force must be applied to pull the sliding bracket. This is very unfriendly to female users with weaker strength.

[0007] In view of the above situation, the inventors have thought of using the lever principle to add a lever structure to the existing roller-type film laminating device to reduce the force applied. The positioning seat can be pushed with a smaller force to complete the film laminating operation.

[0008] In addition, in the current film applicator with a pressure roller, the pressure roller is usually set horizontally, that is, the axis of the pressure roller is parallel to the width direction of the mobile phone. This technical solution of setting the pressure roller horizontally has the following problems:

[0009] As the film enters the second half, small bubbles will appear in the middle area near the end of the mobile phone film. The reason for this is that: under the pressure of the pressure roller, the end edge of the protective film is fitted to the screen of the mobile phone in advance, resulting in the small bubbles being unable to be squeezed out by the pressure roller. At the same time, since the pressure roller will produce slight deformation in the axial direction during the rolling process, the downward pressure generated in the middle area of ​​the pressure roller is insufficient, and the air between the protective film and the mobile phone screen cannot be completely rolled out, which easily leaves small bubbles. Moreover, this undesirable situation will become more and more obvious with the repeated use of the film applicator, and the defective rate of film will also increase significantly.

[0010] In summary, the inventors propose the following technical solutions. Utility model content:

[0011] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a labor-saving tilting film applicator which can greatly reduce the force applied when applying the film and improve the convenience of film application.

[0013] Furthermore, in the above technical solution, one end of the linkage plate is pivotally connected to the force application plate via a first pivot, and the other end of the linkage plate is pivotally connected to the sliding seat via a second pivot.

[0014] Furthermore, in the above technical solution, slide rails or slide grooves are arranged on both sides of the positioning seat; and slide grooves or sliding blocks cooperating with the slide rails or slide grooves arranged on both sides of the positioning seat are arranged on both sides of the sliding seat.

[0015] Furthermore, in the above technical solution, the sliding seat includes: a beam pivotally connected to the linkage plate, and sliding blocks arranged at both ends of the beam and extending downward, and the positioning seat is provided with a sliding groove cooperating with the sliding block.

[0016] Furthermore, in the above technical solution, a limiting block is arranged on the outer side surface of the sliding block, and a limiting groove corresponding to the limiting block is opened on the inner wall of the sliding groove.

[0017] Furthermore, in the above technical solution, the angle formed between the axis of the pressure roller and the transverse direction of the positioning cavity is 5 to 25°.

[0018] Furthermore, in the above technical solution, the pressing roller includes a first pressing roller and a second pressing roller which are parallel to each other.

[0019] Furthermore, in the above technical solution, the force-applying plate is a cover plate matched with the positioning seat, that is, the force-applying plate can be covered on the positioning seat, and a relatively closed box body is formed by the mutual covering of the force-applying plate and the positioning seat.

[0020] Furthermore, in the above technical solution, the axis of the pressure roller is not perpendicular to the direction in which the sliding seat slides along the positioning seat; the lateral direction of the positioning cavity is perpendicular to the direction in which the sliding seat slides along the positioning seat.

[0021] Furthermore, in the above technical solution, the axis of the pressure roller is perpendicular to the direction in which the sliding seat slides along the positioning seat; and the lateral direction of the positioning cavity is not perpendicular to the direction in which the sliding seat slides along the positioning seat.

[0022] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0023] 1. The force plate in the utility model is used as a lever, which forms a linkage mechanism with the linkage plate, wherein the force plate is used as a lever structure, which can generate a large thrust through a small external force, so that the sliding seat pushed by the force plate can slide smoothly along the positioning seat, so that the pressure roller moves relatively from the starting end to the end of the mobile phone, and rolls the protective film covering the top of the mobile phone to complete the attachment of the protective film, and the entire film attachment process is labor-saving.

[0024] 2. In order to further improve the film laminating effect, the utility model adopts that the axis of the pressing roller is not parallel to the lateral direction of the positioning cavity, which can overcome the problem of residual bubbles in existing products and ultimately achieve a good laminating effect.

[0032] The utility model is further described below in conjunction with specific embodiments and drawings.

[0033] See Figures 1 to 6 As shown, the utility model comprises: a force applying plate 1, a positioning seat 2, a sliding seat 3, a pressing roller 4 and a linkage plate 5.

[0034] The force-applying plate 1 as the force-applying component of the utility model plays the role of a lever. One end of the force-applying plate 1 is pivotally connected to one end of the positioning seat 2, that is, the force-applying plate 1 can rotate along the pivotal position between it and the positioning seat 2. As for the specific form, the force-applying plate 1 can directly adopt the shape of a plate, a long rod, etc. with a certain rigidity. In the utility model, in order to make the structure of the entire product beautiful and unified, the force-applying plate 1 is designed to be a cover plate. That is, the force-applying plate 1 is a cover plate that cooperates with the positioning seat 2, that is, the force-applying plate 1 can be covered on the positioning seat 2, and a relatively closed box body is formed by the mutual covering of the force-applying plate 1 and the positioning seat 2.

[0035] A reinforcing rib 10 is arranged in the middle of the inner surface of the cover plate 1, which can improve the rigidity of the force plate 1 and avoid large deformation or even breakage during the film application process. One end of the linkage plate 5 is pivotally connected to the position of the reinforcing rib 10 on the force plate 1.

[0036] The upper end surface of the positioning seat 2 is provided with a positioning cavity 20 for accommodating and positioning the mobile phone 6. The shape of the positioning cavity 20 matches the outer contour of the mobile phone 6 to be filmed. When in use, the mobile phone 6 is placed in the positioning cavity 20, and the mobile phone 4 is positioned through the positioning cavity 20. Positioning protrusions 22 and 23 are provided in the upper and lower outer areas of the positioning cavity 20. These positioning protrusions 22 and 23 are used to position the protective film and are suspended above the positioning cavity 20, waiting for the rolling of the pressure roller 4.

[0037] The sliding seat 3 can be slidably installed on the positioning seat 2, and the pressing roller 4 can be rotatably installed on the lower side of the sliding seat 3. The pressing roller 4 is driven by the sliding seat 3 to slide along the longitudinal direction of the positioning seat 2.

[0038] The sliding connection between the sliding seat 3 and the positioning seat 2 can adopt the following structure: the sliding seat 3 includes: a crossbeam 31 pivotally connected to the linkage plate 5, a slider 32 arranged at both ends of the crossbeam 31 and extending downward, and a slide groove 21 cooperating with the slider 32 is arranged on both sides of the positioning cavity 20 along the positioning seat 2. The slider 32 and the slide groove 21 form a sliding matching structure. In order to limit the sliding seat 3 and prevent the sliding seat 3 from being separated from the positioning seat 2, a limiting block 321 is arranged on the outer side of the slider 32, and a limiting groove 211 corresponding to the limiting block 321 is opened on the inner wall of the slide groove 21. Through the cooperation between the limiting block 321 and the limiting groove 211, the slider 32 is limited in the slide groove 21 to prevent the sliding seat 3 from being separated from the positioning seat 2.

[0039] Of course, the sliding connection between the sliding seat 3 and the positioning seat 2 can also adopt other similar slide rail structures, for example: slide rails are arranged on both sides of the positioning seat 2; and slide grooves cooperating with the slide rails are arranged on both sides of the sliding seat 3.

[0040] The pressure roller 4 is installed between the two sliders 32. When the sliding seat 3 is installed on the positioning seat 2, the pressure roller 4 is located above the positioning seat 2. Specifically, the pressure roller 4 usually includes: a roller body 40 and a roller shaft 41. The roller body 40 is usually made of a cylindrical plastic material, and the roller shaft 41 is a metal shaft passing through the roller body 40. Shaft holes are opened on the inner side surfaces of the sliders 32 on both sides of the sliding seat 3, and the two ends of the roller shaft 41 are rotatably installed in the shaft holes on the two sliders 32.

[0041] The linkage plate 5 is made of a relatively hard plate and connecting rod. One end of the linkage plate 5 is pivotally connected to the force plate 1 through a first pivot 51, and the other end is pivotally connected to the sliding seat 3 through a second pivot 52. Specifically, one end of the linkage plate 5 is pivotally connected to the position of the reinforcing rib 10 of the force plate 1 through the first pivot 51. The sliding seat 3 is provided with a pivot position 311 for installing the linkage plate 5, and pivot holes that cooperate with the second pivot 52 are provided on both sides of the pivot position 311.

[0042] For better explanation, the utility model establishes an XY coordinate system with the transverse direction and the longitudinal direction of the positioning cavity 20, wherein the transverse direction of the positioning cavity 20 is the X-axis and the longitudinal direction is the Y-axis. That is, the transverse direction and the longitudinal direction of the positioning cavity 20 correspond to the width direction and the length direction of the mobile phone 6, respectively. The axis L of the pressure roller 4 of the utility model is not parallel to the transverse direction (X-axis) of the positioning cavity 20, and the angle formed between the two is 3 to 45°. In other words, the axis L of the pressure roller 4 of the utility model is not perpendicular to the longitudinal direction (Y-axis) of the positioning cavity 20, and the angle formed between the two is 3 to 45°.

[0043] Combination Figure 5 , Figure 6 As shown, in order to achieve that the axis L of the pressure roller 4 is not parallel to the transverse direction (X axis) of the positioning cavity 20, the pressure roller 4 is tilted, and its specific structure is as follows: the positioning cavity 20 is arranged in the same manner as the existing product, and the pressure roller 4 is tiltedly installed on the sliding seat 3 relative to the positioning cavity 20, that is, the axis L of the pressure roller 4 is not perpendicular to the sliding direction of the sliding seat 3 along the positioning seat 2; the transverse direction (X axis) of the positioning cavity 20 is perpendicular to the sliding direction of the sliding seat 3 along the positioning seat 2, or it can be said that the longitudinal direction (Y axis) of the positioning cavity 20 is parallel to the sliding direction of the sliding seat 3 along the positioning seat 2.

[0044] If the axis inclination angle of the pressing roller 4 is too large, the length of the pressing roller 4 will increase, and the space required in the longitudinal direction will also increase, which will increase the length of the entire film applicator. Therefore, in the first embodiment, the angle formed between the axis L of the pressing roller 4 and the transverse direction of the positioning cavity 20 is preferably 5 to 25 degrees, and the preferred embodiment is: 10 degrees.

[0045] Combination Figure 7 As shown, when the utility model is used, the mobile phone 6 is placed in the positioning cavity 20 of the positioning seat 2, and the protective film 7 is suspended and positioned above the positioning cavity 20 by the positioning protrusions 22 and 23. Then, the user applies a covering external force to the end of the force plate 1 away from the pivotal connection with the positioning seat 2. The force plate 1 rotates relatively under the action of the external force, and the linkage plate 5 driven by the force plate 1 will push the sliding seat 3 to slide along the positioning seat 2, so that the pressure roller 4 moves from the starting end of the mobile phone 6 to the end end, and while moving, the protective film 7 covering the mobile phone 6 is rolled to complete the attachment of the protective film.

[0046] According to the above-mentioned usage, the force plate 1 and the linkage plate in the utility model constitute a linkage mechanism, wherein the force plate 1 is a lever structure, one end of the linkage plate 5 is pivoted to the middle area of ​​the force plate 1, and the linkage plate 5 is shorter than the first lever arm formed between the pivotal position of the force plate 1 and the positioning seat 2, and the user acts on the farthest side of the force plate 1. The second lever arm applied by the user is the length of the entire force plate 1, and the length of the second lever arm is greater than the length of the first lever arm. A relatively small external force can generate a large thrust on the linkage plate 5, so that it is relatively labor-saving to push the sliding seat 3 to slide through the force plate 1, that is, it is more labor-saving to apply the film, and even female users can easily complete the film application.

[0047] In addition, the utility model adopts a technical solution that the axis of the pressure roller 4 is not parallel to the transverse direction of the positioning cavity 20. The advantages of this design are: Figure 6 As shown, when the sliding seat 3 slides along the positioning seat 2. During the movement of the sliding seat 3 relative to the positioning seat 2, the pressing roller 4 moves relatively from the starting end of the mobile phone 6 in the positioning cavity 20 to the rear end, and rolls the protective film 7 covering the top of the mobile phone while moving relatively. Since the pressing roller 4 is inclined relative to the positioning cavity 20 (i.e., the axis L of the pressing roller 4 is not parallel to the transverse direction of the positioning cavity 20), the pressing roller 4 will first start to roll the screen of the mobile phone 6 from the right corner position of the upper side of the mobile phone 6, and then gradually roll down to the left corner position of the diagonal position of the lower side of the mobile phone 6. If bubbles are formed in the protective film 7 during the rolling process, these bubbles will be gradually squeezed by the pressing roller 4 to the left corner of the lower side of the mobile phone 6. As the pressing roller 4 continues to move downward relative to the mobile phone 6, the area between the protective film 7 and the screen of the mobile phone 6 that is not rolled by the pressing roller 4 becomes smaller and smaller. The narrow area cannot form a space to accommodate bubbles. Under the continuous squeezing action of the pressing roller 4, the bubbles are finally completely discharged from the left corner without any residual bubbles, thereby achieving a perfect fitting effect.

[0048] In addition, the utility model can also adopt another embodiment, in order to achieve that the axis L of the pressure roller 4 is not parallel to the transverse direction (X axis) of the positioning cavity 20, the following structure can be adopted: the pressure roller 4 is set in the same way as the existing product, that is, the pressure roller 4 is set horizontally, and the positioning cavity 20 is tilted relative to the pressure roller 4 on the positioning seat 2, that is, the axis L of the pressure roller 4 is perpendicular to the sliding direction of the sliding seat 3; the transverse direction (X axis) of the positioning cavity 20 is not perpendicular to the sliding direction, or it can be said that the longitudinal direction (Y axis) of the positioning cavity 20 is not parallel to the sliding direction. This method tilts the positioning cavity 20, which has the same working principle as the above-mentioned embodiment, and finally achieves the same film-sticking effect, which will not be repeated here.

[0049] In order to improve the film pasting quality, the rolling element 4 of the utility model can adopt a double roller structure, which includes: a first pressing roller and a second pressing roller arranged in parallel with each other. The double pressing roller design further improves the film pasting effect and completely eliminates bubbles.

[0050] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
