Description

Technical Field

[0001] This application relates to the field of electronic product screen protector technology, and in particular to a screen protector application device and method. Background Technology

[0002] With the development of technology, various electronic devices have emerged, such as mobile phones, tablets, laptops, and smartphones. For these electronic devices with displays, a protective film is applied to the screen at the factory to protect it from scratches during use.

[0003] However, as displays have become larger, foldable electronic devices have emerged to improve their portability. For foldable electronic devices, part or all of the original battery cover area is replaced with a display screen. However, decorative parts may be attached to this area, protruding from the surface of the display screen and making the surface uneven. Due to the presence of decorative parts, most electronic devices currently do not use a screen protector on the surface with decorative parts when they leave the factory. However, during user use, the exposed display screen is easily scratched by hard objects such as keys, resulting in scratches that cannot be repaired and affecting the user experience. Summary of the Invention

[0004] This application provides a film application device and method to solve the technical problem that when the display screen around the decorative parts is not covered with a film, the exposed display screen is easily scratched by hard objects such as keys during user use, resulting in scratches.

[0005] The technical solution is as follows:

[0006] The first aspect of this application provides a film application device, which includes: a support mechanism and a film application mechanism;

[0007] The support mechanism includes a support plate, an adsorption component, and a limiting component. The adsorption component is used to adsorb the electronic device to be coated onto the support plate, and the limiting component is used to limit the opposite sides of the electronic device.

[0008] The coating mechanism is used to cover a protective film onto a designated surface of an electronic device, the designated surface being a surface with decorative elements, and the coating mechanism has a clearance structure for avoiding the decorative elements.

[0009] By adopting the above technical solution, the electronic device is adsorbed and fixed onto the support plate using the adsorption component, and the sides of the electronic device are limited by the limiting component. This reduces the possibility of the electronic device shaking during the film application process. The film-applying mechanism can apply the protective film to the surface of the electronic device with decorative parts, and the avoidance structure prevents damage to the decorative parts, ensuring the safety of the film-applying mechanism during the application process. In this way, after applying the film to the surface around the decorative parts, the display screen around the decorative parts can be protected, thereby improving the user experience and facilitating the automation of the film application process.

[0010] In some implementations, the coating mechanism includes: a first roller, the surface of which has a clearance structure;

[0011] The clearance structure includes a groove structure configured to accommodate the decorative element when the first roller rotates.

[0012] By adopting the above solution, after setting the groove structure on the surface of the first roller, since the surface of the first roller is curved, the decorative part will gradually enter the groove structure as the first roller rolls. This can not only avoid the first roller damaging the decorative part, but also roll the protective film of the circumferential area of ​​the decorative part in all directions, so that the protective film can fit well with the set surface.

[0013] In some implementations, the coating mechanism further includes: a first support and a reset assembly, wherein the first roller is mounted on the first support; the reset assembly is used to align a first positioning mark on the first roller with a second positioning mark on the first support.

[0014] By adopting the above solution, the reset component can restore the first roller to its initial position after rolling, so that when the first roller is rolled a second time or when rolling a protective film on another electronic device, the decorative part can also enter the groove structure during the rolling process, thereby playing a protective role for the decorative part.

[0015] In some implementations, the reset assembly includes a first magnet and a second magnet that can attract the first magnet. The first magnet is fixed to the end of the first roller and is located at a first positioning mark. The second magnet is fixed to the first bracket and is located at a second positioning mark.

[0016] Alternatively, the reset assembly includes a photoelectric switch and a light-blocking plate, one of which is mounted on the second positioning mark on the first bracket, and the other is mounted on the first positioning mark on the first roller;

[0017] Alternatively, the reset assembly includes a coil spring, one end of which is connected to the first roller, and the other end of which is connected to the first bracket.

[0018] By employing the above scheme, when the first magnet and the second magnet attract each other, the first magnet and the second magnet attract each other when the first roller rotates one revolution, thereby aligning the first positioning mark with the second positioning mark. When a coil spring is used, the elasticity of the coil spring achieves the reset of the first roller.

[0019] In some implementations, the cross-section of the first roller is circular or fan-shaped.

[0020] By adopting the above scheme, when the cross-section of the first roller is circular, the diameter of the first roller can be controlled so that the circumference of one rotation of the first roller is equal to the length of the protective film. In this way, when the first roller rotates one rotation, the first positioning mark is just aligned with the second positioning mark again. When the cross-section of the first roller is fan-shaped, the arc length corresponding to the fan-shaped cross-section is equal to the length of the protective film. In this way, after the first roller swings a certain angle, the first positioning mark can be aligned with the second positioning mark again by the reset component.

[0021] In some implementations, the coating mechanism includes a second roller and a third roller; the second roller and the third roller respectively roll over different areas of the set surface;

[0022] The avoidance structure includes a second roller and a third roller, and the areas rolled by the second roller and the third roller respectively avoid the decorative parts.

[0023] By adopting the above scheme, the second and third rollers are used to roll different areas around the decorative part. In this way, the second and third rollers can avoid the decorative part, thereby achieving protection of the decorative part during the film application process.

[0024] In some implementations, the axis of the second roller is parallel to the axis of the third roller.

[0025] By adopting the above solution, the second and third rollers can work simultaneously, or the design of the film application equipment can be simplified.

[0026] In some implementations, the laminating mechanism includes a first film suction mechanism and a second film suction mechanism;

[0027] The first film suction mechanism is used to adsorb the first preset portion of the protective film;

[0028] The second suction film mechanism is used to adsorb the second preset portion of the protective film, and the second suction film mechanism can rotate relative to the first suction film mechanism to move the protective film above the set surface.

[0029] By adopting the above scheme, the first and second film suction mechanisms work together to fix the protective film before applying the film so that the release film on the protective film can be peeled off. Since the first and second film suction mechanisms respectively adsorb different parts of the protective film, when the second film suction mechanism rotates relative to the first film suction mechanism, some areas of the protective film will no longer be adsorbed. In this way, when the protective film moves above the set surface, the first roller or the second roller and the third roller can work together to gradually roll the protective film onto the set surface.

[0030] In some implementations, the first film suction mechanism includes a first film suction plate and a first positioning block, wherein the first film suction plate has multiple negative pressure through holes;

[0031] At least one side of the first suction plate is fixed with a first positioning block.

[0032] By adopting the above scheme, the first positioning block can be used to position the protective film adsorbed on the first suction plate, which helps to improve the accuracy of the protective film being applied to electronic devices.

[0033] In some implementations, the second film suction mechanism includes a second film suction plate, a second positioning block, and a first driving mechanism;

[0034] The second suction plate has multiple negative pressure through holes;

[0035] At least one side of the second suction plate is fixed with a second positioning block;

[0036] The first drive mechanism is used to enable the second suction plate to rotate about the first axis relative to the first suction plate.

[0037] By adopting the above scheme, the second positioning block can be used to position the protective film adsorbed on the second suction plate, which helps to improve the accuracy of the protective film being applied to electronic devices.

[0038] In some implementations, the film-coating mechanism also includes a film-supporting mechanism located on one side of the support plate;

[0039] The film support mechanism is configured to support one side of the protective film when the second film suction mechanism moves the protective film above the set surface, so that there is an angle between the protective film and the set surface.

[0040] By adopting the above solution, the protective film can be placed at an angle relative to the set surface during the film application process using the film support mechanism. This allows air to be smoothly expelled during the application process, resulting in a smoother application of the protective film. This ensures that no bubbles or wrinkles appear on the surface of the film, while also ensuring a tighter contact between the protective film and the set surface, providing better protection.

[0041] In some implementations, the film support mechanism includes a first support block and a first linear motion device; the first linear motion device is used to drive the first support block to make linear motion, and the direction of motion of the first support block is parallel to the surface of the support plate.

[0042] By adopting the above method, the protective film can be gradually applied to the designated surface, improving the uniformity of the adhesion between the protective film and the designated surface.

[0043] In some implementations, the film support mechanism also includes an elastic component, and the first support block is connected to the first linear moving device through the elastic component;

[0044] The elastic component includes a first fixed block, a second fixed block, a first guide post, and a first spring. The first support block is fixed on the first fixed block, and the first fixed block is fixedly connected to one end of the first guide post. The other end of the first guide post is limited to the second fixed block, and the first guide post and the second fixed block are slidably connected. The first spring is sleeved on the first guide post, and the two ends of the first spring abut against the first fixed block and the second fixed block, respectively.

[0045] The first linear motion device is used to drive the second fixed block to make linear motion, so that the first support block makes linear motion.

[0046] By adopting the above solution, the elastic component can be used to buffer the movement of the first support block, thus preventing the second suction film mechanism from damaging the first support block.

[0047] In some implementations, the film coating mechanism includes a film suction plate for adsorbing the protective film and covering the protective film onto a designated surface;

[0048] The suction plate has clearance holes for accommodating decorative elements, and the clearance structure includes clearance holes.

[0049] By adopting the above solution, the protective film can be applied to the designated surface in a manner where the protective film is parallel to the designated surface.

[0050] In some implementations, the coating mechanism also includes a degassing device, which uses compressed gas to act on the protective film attached to the set surface to remove air bubbles between the protective film and the set surface.

[0051] By adopting the above solution, the protective film can be placed parallel to the set surface using a suction plate. After the protective film is placed on the set surface, the bubble removal equipment can be used to remove the air bubbles formed during the film application process, thereby improving the flatness of the bonding.

[0052] In some implementations, the limiting component includes two limiting parts disposed on opposite sides of the support plate. Each limiting part includes a stop block and a second linear moving device. The second linear moving device is used to make the stop block move linearly, so that the stop block can move to the side of the electronic device.

[0053] By adopting the above solution, the positioning component is used to fix the position of the electronic device on the support plate, thereby improving the accuracy of the film application process.

[0054] In some implementations, the film application equipment also includes an edge pressing mechanism that can be moved to a set surface to roll the edges of the protective film covering the set surface on opposite sides.

[0055] By adopting the above solution, the edge pressing mechanism can be used to roll the edge of the protective film, which can squeeze out the air bubbles between the protective film and the screen to ensure the flatness of the surface, increase the adhesion between the protective film and the set surface, and make the edge of the protective film smoother, eliminating wrinkles and irregular shapes.

[0056] In some implementations, the edge pressing mechanism includes an edge roller and a first spatial moving device. The first spatial moving device is used to move the edge roller to the edge of the protective film, and the edge roller is used to roll the edge of the protective film.

[0057] By adopting the above method, the edge of the protective film can be made smoother by using edge rollers, eliminating wrinkles and irregular shapes.

[0058] A second aspect of this application provides a film application method, using any of the film application devices described above, the film application method comprising:

[0059] Electronic devices with decorative elements can be detachably fixed to the support mechanism;

[0060] A protective film is applied to the surface of an electronic device with decorative elements by a coating mechanism, and during the coating process, the avoidance structure of the coating mechanism can avoid the decorative elements.

[0061] By adopting the above solution, the electronic device is adsorbed and fixed onto the support plate using the adsorption component, and the sides of the electronic device are limited by the limiting component. This reduces the possibility of the electronic device shaking during the film application process. The film-applying mechanism can apply the protective film to the surface of the electronic device with decorative parts, and the avoidance structure prevents damage to the decorative parts, ensuring the safety of the film-applying process. In this way, after applying the film to the surface around the decorative parts, the display screen around the decorative parts can be protected, thereby improving the user experience.

[0062] In some implementations, during the lamination process, the avoidance structure of the lamination mechanism can avoid the decorative element, including:

[0063] The first roller of the coating mechanism is rolled on the surface with the decorative element, wherein the groove structure on the first roller is capable of accommodating the decorative element.

[0064] By adopting the above solution, after setting the groove structure on the surface of the first roller, since the surface of the first roller is curved, the decorative part will gradually enter the groove structure as the first roller rolls. This can not only avoid the first roller damaging the decorative part, but also roll the protective film of the circumferential area of ​​the decorative part in all directions, so that the protective film can fit well with the set surface.

[0065] In some implementations, during the lamination process, the avoidance structure of the lamination mechanism can avoid the decorative element, including:

[0066] The second and third rollers of the coating mechanism roll different areas of the surface with the decorative element, respectively, wherein the areas rolled by the second and third rollers avoid the decorative element.

[0067] By adopting the above scheme, the second and third rollers are used to roll different areas around the decorative part. In this way, the second and third rollers can avoid the decorative part, thereby achieving protection of the decorative part during the film application process.

[0068] In some implementations, during the lamination process, the avoidance structure of the lamination mechanism can avoid the decorative element, including:

[0069] Insert the decorative piece into the clearance hole on the suction plate of the film-coating mechanism so that the protective film covers the surface with the decorative piece;

[0070] The degassing device of the coating mechanism uses compressed gas to act on the protective film attached to the set surface to remove air bubbles between the protective film and the set surface.

[0071] By adopting the above solution, the protective film can be applied to the set surface in a way that the protective film is parallel to the set surface, and the air bubbles formed during the film application process can be removed by the debubbling equipment.

[0072] In some implementations, the electronic device with decorative elements is detachably fixed to the support plate, including:

[0073] The electronic device is attached to the support plate of the support mechanism;

[0074] The first linear movement device of the support mechanism is used to make the side block move linearly, so that the side block moves to the side of the electronic device.

[0075] By adopting the above solution, the positioning component is used to fix the position of the electronic device on the support plate, thereby improving the accuracy of the film application process. Attached Figure Description

[0108] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0109] It should be understood that "multiple" as mentioned in this application refers to two or more. In the description of this application, unless otherwise stated, " / " indicates "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist, for example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, to facilitate a clear description of the technical solutions of this application, the terms "first," "second," etc., are used to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and that "first," "second," etc., do not necessarily imply differences.

[0110] Figure 1 This is a state diagram of the screen film 401 being attached to the electronic device 201 in the related technology. See [link / reference] Figure 1 As shown, for electronic devices 201, such as mobile phones, tablets, laptops, or e-readers, a screen protector 401 is typically applied to the screen of the electronic device 201 using a roller 402 at the factory to protect its screen. See also... Figure 2 As shown, Figure 2 This diagram illustrates the state of a protective film 301 applied to an electronic device 201 with a decorative element 202, as described in the related art. With the advent of foldable electronic devices 201, a display screen may replace part or all of the original battery cover area. However, a decorative element 202 may still be applied here; this element could be a lens ring fitted onto a camera to protect it. The protective film 301 has a clearance hole 302 through which the decorative element 202 can pass and be applied to the display screen. However, due to the presence of the decorative element 202, manual application is inefficient. Therefore, for factory-made electronic devices 201, a film-free application method is adopted. However, during user operation, the exposed display screen is easily scratched by hard objects such as keys, resulting in irreparable scratches and affecting the user experience. Therefore, this application provides a film application device and method to solve the above problems. The film application device and method provided in this application will be explained in detail below.

[0111] Figure 3 This is a schematic diagram of the support mechanism 100 in the embodiments of this application. Figure 4 This is a state diagram of the electronic device 201 located on the support mechanism 100 in an embodiment of this application; combined with Figure 3 and Figure 4As shown; in one or more embodiments, the film application device provided in this application includes a support mechanism 100, which supports the electronic device 201 to be applied with film and allows the electronic device 201 to be detachably fixed thereon, thus facilitating the accuracy of the film application process. The support mechanism 100 includes a support plate 101, an adsorption component 102, and a limiting component 103; the adsorption component 102 is used to adsorb the electronic device 201 to be applied with film onto the support plate 101, and the limiting component 103 is used to limit the opposite two sides of the electronic device 201.

[0112] Combination Figure 3 and Figure 4 As shown, in some embodiments, the film application device further includes a film coating mechanism 105, which is used to apply the film to the film. Figure 2 The protective film 301 shown is applied to a designated surface of the electronic device 201, which is the surface with the decorative element 202. The film application mechanism 105 has a clearance structure for avoiding the decorative element 202. Thus, the film application device provided in at least one embodiment of this application uses the adsorption component 102 to adsorb and fix the electronic device 201 onto the support plate 101, and then uses the limiting component 103 to limit the sides of the electronic device 201. This reduces the possibility of the electronic device 201 shaking during the film application process. The film application mechanism 105 can apply the protective film 301 to the surface of the electronic device 201 with the decorative element 202, and the clearance structure prevents damage to the decorative element 202, ensuring the safety of the film application process. By applying the film to the surface around the decorative element 202, the display screen around the decorative element 202 can be protected, thereby improving the user experience. Furthermore, compared to manual application, the improved film application equipment of this application reduces the occurrence of white edges and air bubbles at the junction of the protruding decorative parts 202 and the display screen, thereby improving the application efficiency and yield stability of the protective film 301. It should be noted that the film application equipment provided in this application is not limited to the application of protective films 301 on the displays of terminal products such as electronic devices 201, but can also be applied to protective film 301 application scenarios in other fields.

[0113] For ease of description, the width direction of the film-applying device is defined as the BB direction, the length direction as the AA direction, and the thickness direction as the CC direction. The AA, BB, and CC directions are mutually perpendicular. The length direction of the support plate 101 is parallel to the AA direction, the thickness direction is parallel to the CC direction, and the width direction is parallel to the BB direction; the first direction is parallel to the AA direction, the second direction is parallel to the CC direction, and the third direction is parallel to the BB direction. The length of the protective film 301 is parallel to the AA direction; the width of the protective film 301 is parallel to the BB direction.

[0114] Combination Figure 3 and Figure 4 As shown, in some embodiments, the support plate 101 has an opening 106, and the adsorption assembly 102 includes a vacuum suction cup 107 and a vacuum pump (not shown). The vacuum suction cup 107 extends into the opening 106. The vacuum pump is connected to the vacuum suction cup 107. After the electronic device 201 is placed on the support plate 101, the vacuum pump draws a vacuum, causing the vacuum suction cup 107 to adsorb the lower surface of the electronic device 201, thereby adsorbing the electronic device 201 onto the support plate 101. It should be noted that the electronic device 201 can be picked up and placed on the support plate 101 manually, or a robotic arm can be used to pick up and place the electronic device 201 on the support plate 101. The limiting component 103 includes two limiting parts disposed on opposite sides of the support plate 101. Each limiting part includes a stop block 108 and a second linear moving device 109. The second linear moving device 109 is used to make the stop block 108 move linearly, so that the stop block 108 can move to the side of the electronic device 201. In this way, the limiting component 103 is used to fix the position of the electronic device 201 on the support plate 101, thereby improving the accuracy of the film application process. The edge blocks 108 are located on the two long sides of the support plate 101, and the long sides of the support plate 101 are parallel to the length direction of the support plate 101. The second linear moving device 109 can be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, or a linear motor, etc., to realize the linear movement of the edge blocks 108, that is, the lifting and lowering movement of the edge blocks 108. The edge blocks 108 limit the movement of the electronic device 201 on both sides in the length direction. The lifting and lowering height of the edge blocks 108 by the second linear moving device 109 can be determined according to the actual situation. When the display screen of the electronic device 201 needs to have a 3D curved surface, the protective film 301 is adapted to the 3D curved surface. When rolling the 3D curved surface, the upper surface of the edge blocks 108 needs to be lowered to facilitate rolling. When the display screen of the electronic device 201 does not have a 3D curved surface, the height of the edge blocks 108 can be appropriately increased.

[0115] Combination Figure 3 and Figure 4As shown, in some embodiments, to ensure that the edge block 108 does not rotate during the lifting and lowering process, linear slide rails 110 are respectively provided at both ends of the edge block 108, and the edge block 108 is fixed to the slider of the linear slide rail 110. The film application equipment also includes a frame 111, a support plate 101 is fixed on the frame 111, and the guide rail of the linear slide rail 110 is fixed on the frame 111, thus ensuring the linear movement of the edge block 108. The two opposite wide sides of the support plate 101 are each provided with a fixed limit block 112. The limit block 112 has an oblong through hole, and is fixed to the frame 111 by screws passing through the oblong through hole. Since it is an oblong through hole, the limit block 112 can be moved along the length direction of the support plate 101 to adjust the fixed position of the limit block 112 to adapt to electronic devices 201 of different lengths.

[0116] See Figure 3 and Figure 4 As shown, in some embodiments, the film-coating mechanism 105 includes a film-supporting mechanism 113, which is located on one side of the support plate 101. The film-supporting mechanism 113 supports one side of the protective film 301, creating an angle between the protective film 301 and the set surface. This allows the protective film 301 to be placed at an angle relative to the set surface during the film-coating process, facilitating air expulsion and resulting in a smoother application of the protective film 301. This ensures that no bubbles or wrinkles appear on the surface of the film and also ensures a tighter contact between the protective film 301 and the set surface, providing better protection. The film-supporting mechanism 113 includes a first support block 114 and a first linear movement device 115. The first linear movement device 115 drives the first support block 114 in a linear motion, with the direction of movement of the first support block 114 parallel to the surface of the support plate 101. This allows the protective film 301 to gradually adhere to the set surface, improving the neatness of the adhesion between the protective film 301 and the set surface.

[0117] See Figure 3 and Figure 4As shown, in some embodiments, the film support mechanism 113 further includes an elastic component, and the first support block 114 and the first linear movement device 115 are connected by the elastic component; the elastic component includes a first fixing block 116, a second fixing block 117, a first guide post 118 and a first spring 119. The first support block 114 is fixed to the first fixing block 116. Specifically, the first support block 114 has a supporting inclined surface 120, and there is an angle between the supporting inclined surface 120 and the surface of the support plate 101. This angle can be equal to the angle between the protective film 301 and the set surface. The first support block 114 can be fixed to the first fixing block 116 by screws. For example, the first support block 114 has an oblong through hole, so that screws can be passed through the oblong through hole to connect with the first fixing block 116, thereby fixing the first support block 114 to the first fixing block 116. The oblong through hole can allow the first support block 114 to move axially along the first guide post 118 relative to the first fixing block 116, so that the position of the first support block 114 on the first fixing block 116 can be adjusted. This makes it easy to adjust the position of the first support block 114 supporting the protective film 301.

[0118] See Figure 3 and Figure 4As shown, in some embodiments, the first fixing block 116 is fixedly connected to one end of the first guide post 118, for example, the first fixing block 116 and the first guide post 118 are fixedly connected by screws. The other end of the first guide post 118 is limited to the second fixing block 117, and the first guide post 118 and the second fixing block 117 are slidably connected. Specifically, the second fixing block 117 has a mounting through hole, and the elastic component also includes a stop plate 121. After the other end of the first guide post 118 passes through the mounting through hole, the stop plate 121 is fixedly connected to the other end of the first guide post 118. The fixing method between the stop plate 121 and the first guide post 118 can be screw fixing or threaded connection between the first guide post 118 and the stop plate 121. In this way, the stop plate 121 enables the other end of the first guide post 118 to be limited to the second fixing block 117, and the first guide post 118 can slide relative to the second fixing block 117. The first spring 119 is sleeved on the first guide post 118, and its two ends abut against the first fixed block 116 and the second fixed block 117 respectively, thus limiting the first spring 119 to be located between the first fixed block 116 and the second fixed block 117. The first linear moving device 115 is used to drive the second fixed block 117 to make linear movement, so that the first support block 114 makes linear movement, thus the elastic component can buffer the movement of the first support block 114. The first linear moving device 115 can be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, or a pneumatic slide. For example, when the first linear moving device 115 is a pneumatic slide, the second fixed block 117 is fixed to the slider of the first linear moving device 115; the slide rail of the first linear moving device 115 is fixed to the frame 111.

[0119] See Figure 3 and Figure 4 As shown, in some embodiments, the film-supporting mechanism 113 may further include a second support block 122. The second support block 122 and the first support block 114 are vertically spaced apart in the thickness direction of the support plate 101. The first support block 114 is located above the second support block 122. The second support block 122 also has a supporting inclined surface 120. The distance between the bottom edge of the supporting inclined surface 120 of the first support block 114 and the second fixing block 117 is smaller than the distance between the bottom edge of the supporting inclined surface 120 of the second support block 122 and the second fixing block 117. The distance is such that the bottom edge of the supporting slope 120 of the first support block 114 and the bottom edge of the supporting slope 120 of the second support block 122 are misaligned in the thickness direction of the support plate 101; during the rolling process of the protective film 301, after the protective film 301 is rolled a certain distance, the first linear moving device 115 moves a certain distance with the second fixing block 117, so that the protective film 301 will fall from the supporting slope 120 of the first support block 114 onto the supporting slope 120 of the second support block 122.

[0120] Figure 5This is a schematic diagram of the structure of the first roller 123 in the embodiment of this application, wherein... Figure 5 A diagram also shows the state of the first roller 123 rolling the protective film 301 on the electronic device 201; see also Figure 5 As shown, in some embodiments, the coating mechanism 105 includes: a first roller 123, the surface of which has a clearance structure; the clearance structure includes a groove structure 124, which is configured to accommodate the decorative element 202 when the first roller 123 rotates. Thus, after the groove structure 124 is provided on the surface of the first roller 123, since the surface of the first roller 123 is curved, the decorative element 202 will gradually enter the groove structure 124 as the first roller 123 rolls. This avoids damage to the decorative element 202 by the first roller 123 and allows for all-around rolling of the protective film 301 in the circumferential area of ​​the decorative element 202, ensuring good adhesion between the protective film 301 and the designated surface. The rotation axis 144 of the first roller 123 is parallel to a third direction. See also... Figure 5 As shown, for example, the first roller 123 is a columnar structure with a circular cross-section and a certain length, the length of which is greater than the diameter of the first roller 123. The groove structure 124 is on the cylindrical surface of the first roller 123, and the position of the groove structure 124 is adapted to the position of the decorative part 202 on the electronic device 201. In this way, when the first roller 123 rolls the protective film 301, the decorative part 202 can gradually enter the groove structure 124 when the first roller 123 rolls to the decorative part 202. The avoidance structure avoids the protruding decorative part 202 and ensures the adhesion effect between the display screen and the protective film 301, improving the efficiency of film application and reducing the occurrence of defects such as white edges and bubbles.

[0121] It should be noted that in some other possible implementations, the first roller 123 may only be responsible for rolling the protective film 301 on a local area of ​​the set surface, while other areas may be rolled by other methods or other rollers.

[0122] See Figure 5 As shown, in some embodiments, when the first roller 123 is a cylindrical structure and its cross-section is circular, the diameter of the first roller 123 can be controlled so that the circumference of one rotation of the first roller 123 is equal to the length of the protective film 301. This ensures that the protective film 301 is completely rolled over during one rotation of the first roller 123. Of course, in other possible embodiments, the length of the protective film 301 can also be an integer multiple of the circumference of one rotation of the first roller 123, such as two, three, four, or five times the circumference.

[0123] Figure 6 This is a schematic diagram of another modified structure of the first roller 123 provided in the embodiments of this application; see also Figure 6 As shown, in some embodiments, the cross-section of the first roller 123 is circular, and the diameter of the cross-section of the first roller 123 gradually increases from the middle to both ends, so that the first roller 123 can be applied to electronic devices 201 with a 3D curved display screen.

[0124] Figure 7 This is a schematic diagram of another modified structure of the first roller 123 provided in the embodiments of this application; see also Figure 7 As shown, in some embodiments, the first roller 123 includes a connecting portion 125 and a fan-shaped portion 126 connected to the connecting portion 125. The rotation axis 144 of the first roller 123 is located on the connecting portion 125. The cross-section of the fan-shaped portion 126 of the first roller 123 is basically fan-shaped. The groove structure 124 is located on the curved surface of the first roller 123. When the cross-section of the first roller 123 is fan-shaped, the arc length of the fan shape can be equal to the length of the protective film 301. In this way, when the first roller 123 rotates at a set angle, it can achieve full rolling of the protective film 301. The set angle is the degree of the central angle corresponding to the fan shape. The center of the circle corresponding to the fan shape is on the axis of rotation of the first roller 123.

[0125] Figure 8 This is a schematic diagram of the structure of the first roller 123 mounted on the first bracket 127 in an embodiment of this application; see also Figure 8 As shown, in some embodiments, the coating mechanism 105 further includes a first support 127 and a reset assembly. The first roller 123 is mounted on the first support 127. For example, the first roller 123 is mounted on the first support 127 via a bearing seat. The reset assembly is installed between the first roller 123 and the first support 127 to align the first positioning mark on the first roller 123 with the second positioning mark on the first support 127. In this way, the reset assembly can restore the first roller 123 to its initial position after rolling, so as to ensure that when the first roller 123 is rolled a second time or when rolling the protective film 301 on another electronic device 201, the decorative part 202 can also enter the groove structure 124 during the rolling process, thereby playing a protective role for the decorative part 202.

[0126] See Figure 8As shown, in some embodiments, the coating mechanism 105 further includes a second support 128 on which a fourth roller 129 is mounted. Exemplarily, the fourth roller 129 is mounted on the second support 128 via a bearing seat. The fourth roller 129 has a circular cross-section, and the diameter of the cross-section of the fourth roller 129 gradually increases from the middle to both ends. This allows the fourth roller 129 to be suitable for electronic devices 201 with a 3D curved display screen. When the display screen is 3D curved and there are no decorative elements 202 interfering with the display screen, this allows for rolling of the protective film 301 without avoidance holes 302. Of course, in some other possible implementations, the fourth roller 129 can also be the first roller 123, that is, the film application device has two first rollers 123, one of which is a cylindrical structure, which is suitable for 2D displays, that is, displays that are flat; the other first roller 123 is a column whose cross-sectional diameter gradually increases from the middle to both ends, which is suitable for 2.5D displays or 3D displays.

[0127] Figure 9 This is a schematic diagram of a portion of the structure of the film-applying device in an embodiment of this application; combined with Figure 8 and Figure 9 As shown, in some embodiments, the coating mechanism 105 includes a second spatial movement device, which enables the first support 127 to move along a first direction, and then enables the first support 127 to move along a second direction. The second spatial movement device includes a third linear movement device 130 and a linear drive mechanism 131. The first support 127 and the second support 128 are respectively fixed on two different third linear movement devices 130. The third linear movement device 130 corresponding to the first support 127 enables the first support 127 to move along the second direction, i.e., move up and down; the third linear movement device 130 corresponding to the second support 128 enables the second support 128 to move along the second direction, i.e., move up and down; the linear drive mechanism 131 is used to drive the first support 127 and the second support 128 to move along the first direction, so as to realize the movement of the first roller 123 and the fourth roller 129 along the length direction of the protective film 301, thereby achieving rolling of the protective film 301.

[0128] Combination Figure 8 and Figure 9As shown, in some embodiments, the third linear motion device 130 can be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, or an electric slide. The linear drive mechanism 131 can be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, an electric slide, or a pneumatic slide. For example, taking a pneumatic cylinder as the third linear motion device 130 and an electric slide as the linear drive mechanism 131 as an example, the following description is provided: There are two third linear motion devices 130. The cylinder body of the third linear motion device 130 is fixed to the first mounting plate 132. The first bracket 127 and the second bracket 128 are respectively fixedly connected to the piston rod of their respective third linear motion devices 130. The first bracket 127 and the second bracket 128 are U-shaped. A linear slide rail 110 is provided between the first bracket 127 and the first mounting plate 132. The first bracket 127 is fixedly connected to the slider of the linear slide rail 110, and the first mounting plate 132 is fixedly connected to the guide rail of the linear slide rail 110. The smooth lifting and lowering of the first bracket 127 is achieved through the linear slide rail 110. A linear slide rail 110 is provided between the second bracket 128 and the first mounting plate 132. The second bracket 128 is fixedly connected to the slider of the linear slide rail 110, and the first mounting plate 132 is fixedly connected to the guide rail of the linear slide rail 110. The smooth lifting and lowering movement of the second bracket 128 is achieved through the linear slide rail 110. The first mounting plate 132 is fixedly connected to the slider of the linear drive mechanism 131, and the slide rail of the linear drive mechanism 131 is fixedly connected to the frame 111. In this way, the linear drive mechanism 131 drives the first mounting plate 132 to move, so that the first bracket 127 and the second bracket 128 move together in the first direction. Since the first bracket 127 and the second bracket 128 are driven by different third linear movement devices 130, the first bracket 127 and the second bracket 128 can move in the second direction respectively, that is, they can be lifted and lowered in the second direction respectively, while sharing a single first mounting plate 132 simplifies control.

[0129] It should be noted that the rotation of the first roller 123 and the fourth roller 129 can be achieved by the linear drive mechanism 131, that is, the first roller 123 and the second roller 154 respectively achieve the rotation by friction with the protective film 301; or, at least one of the first roller 123 and the second roller 154 is driven by a motor to achieve its own rotation.

[0130] Figure 10 This is a schematic diagram of the structure of the reset assembly cooperating with the first roller 123; Figure 11 for Figure 10 A magnified view of a portion of point D; combined with... Figure 10 and Figure 11As shown, in some embodiments, the reset assembly includes a first magnet 133 and a second magnet 134 that is attracted to the first magnet 133; the first magnet 133 is fixed to the end of the first roller 123 and is located at a first positioning mark; exemplaryly, a rotating block 135 is fixed to the end of the first roller 123, and the first magnet 133 is embedded in the rotating block 135. The second magnet 134 is fixed to... Figure 8 On the first bracket 127 shown, the second magnet 134 is located at the second positioning mark. By employing the mutual attraction between the first magnet 133 and the second magnet 134, when the first roller 123 rotates once, the first magnet 133 and the second magnet 134 attract each other, thereby aligning the first positioning mark with the second positioning mark. It is understandable that in some other possible implementations, when the cross-section of the first roller 123 is circular and the circumference of one rotation of the first roller 123 is equal to the length of the protective film 301, the first positioning mark is just aligned with the second positioning mark again when the first roller 123 rotates one rotation. When the cross-section of the first roller 123 is fan-shaped, the arc length corresponding to the fan-shaped cross-section is equal to the length of the protective film 301. In this way, after the first roller 123 rotates a certain angle, the first positioning mark can be aligned with the second positioning mark again by the reset component. In this case, the strength of the first magnet 133 and the second magnet 134 can be increased. Although the first roller 123 has rotated a certain angle, it is still within the magnetic field range where the first magnet 133 and the second magnet 134 attract each other. In this way, when the third linear moving device 130 raises the first support 127, the first roller 123 is reset under the attraction of the first magnet 133 and the second magnet 134.

[0131] Figure 12 This is a schematic diagram of another modified structure for the reset assembly to cooperate with the first roller 123, wherein, Figure 12 The reset component and Figure 11 The reset components differ in some embodiments; in others, the reset component includes a photoelectric switch 162 and a light-blocking plate 163, with the photoelectric switch 162 cooperating with the light-blocking plate 163. One of the photoelectric switch 162 and the light-blocking plate 163 is mounted at a second positioning mark on the first bracket 127, and the other is mounted at a first positioning mark on the first roller 123. Thus, by cooperating with the light-blocking plate 163, the photoelectric switch 162 enables the first roller 123 to rotate a preset number of times. The photoelectric switch 162 can be a through-beam photoelectric switch, a reflector photoelectric switch, or a diffuse reflector photoelectric switch.

[0132] For example, the reference Figure 12As shown, this application takes the example of a photoelectric switch 162 mounted on a first bracket 127 and a light-blocking plate 163 mounted on a first roller 123 for specific illustration. The photoelectric switch 162 is fixed on the first bracket 127, and one end of the light-blocking plate 163 is fixedly connected to one end of the first roller 123. The photoelectric switch 162 is a diffuse reflection type photoelectric switch. After the first roller 123 rolls a set distance, the light-blocking plate 163 blocks the light emitted by the light emitter of the photoelectric switch 162 and reflects part of the light to the light receiver of the photoelectric switch 162. At this time, the linear drive mechanism 131 stops driving the first roller 123 to rotate. To provide a damping effect when the first roller 123 rotates, the reset assembly also includes a motor mounted on the first bracket 127. The motor and the first roller 123 are driven by a synchronous belt. This motor can also drive the rotation of the first roller 123. When the first roller 123 rotates a distance exceeding a preset distance, the motor can drive the first roller 123 to rotate again. The photoelectric switch 162 and the light-blocking plate 163 then calibrate the position of the first roller 123, ensuring that the first positioning mark and the second positioning mark are realigned. When the cross-section of the first roller 123 is circular, after the first roller 123 rotates a set distance (e.g., after one revolution), the light-blocking plate 163 triggers the photoelectric switch 162. At this time, the first positioning mark is realigned with the second positioning mark. The photoelectric switch 162 then stops the linear drive mechanism 131 from driving the first bracket 127 to continue moving in the first direction, thus completing one rolling cycle. It is understandable that when the circumference of the first roller 123 rotates once is equal to the length of the protective film 301, the first positioning mark will be aligned with the second positioning mark again when the first roller 123 rotates once. In order to ensure alignment, the first roller 123 is driven to rotate by a motor, and automatic calibration is achieved in conjunction with the photoelectric switch 162 and the light blocking plate 163.

[0133] It should be noted that in some other possible embodiments, when the cross-section of the first roller 123 is fan-shaped, and the arc length corresponding to the fan-shaped cross-section is equal to the length of the protective film 301, the number of photoelectric switches 162 can be two, namely the first photoelectric switch 162 and the second photoelectric switch 162; the first bracket 127 also has a third positioning mark, with the first photoelectric switch 162 located at the second positioning mark and the second photoelectric switch 162 located at the third positioning mark; when the light-blocking plate 163 blocks the second photoelectric switch 162... The emitted light indicates that the first roller 123 has rotated from the starting position to the ending position. At this time, the second photoelectric switch 162 stops the linear drive mechanism 131 from driving the first bracket 127 to continue moving in the first direction. After the first bracket 127 is raised, the motor drives the first roller 123 to rotate in the opposite direction. When the light-blocking plate 163 blocks the light emitted by the first photoelectric switch 162, it indicates that the first roller 123 has rotated back from the ending position to the starting position, realizing the reset of the first roller 123, that is, realizing the realignment of the first positioning mark with the second positioning mark. In some other possible embodiments, the reset component can also be a motor with an encoder. The first roller 123 is connected to the motor, so that the rotation angle of the first roller 123 can be recorded by the encoder. After the first roller 123 rotates several times, since the encoder has recorded the rotation angle of the first roller 123, the motor can be rotated to make the first roller 123 return to the initial rotation state, that is, the first positioning mark is aligned with the second positioning mark. In some embodiments, the reset assembly may include a coil spring, one end of which is connected to the first roller 123 and the other end of which is connected to the first bracket 127. Thus, when the first roller 123 rolls a certain distance, that is, after the first roller 123 has finished rolling the protective film 301, when the first bracket 127 is raised and the first roller 123 leaves the protective film 301, the first roller 123 returns to its initial position under the elastic force of the coil spring, that is, the first positioning mark is aligned with the second positioning mark.

[0134] Figure 13 A schematic diagram of the structure in which the first film suction mechanism 136 and the second film suction mechanism 137 cooperate, as provided in the embodiments of this application; Figure 14 This is a schematic diagram of another state in which the first suction mechanism 136 and the second suction mechanism 137 cooperate, as provided in the embodiments of this application; combined with Figure 13 and Figure 14As shown, in some embodiments, the laminating mechanism 105 includes a first film suction mechanism 136 and a second film suction mechanism 137. The first film suction mechanism 136 is used to suction a first preset portion of the protective film 301; the second film suction mechanism 137 is used to suction a second preset portion of the protective film 301, and the second film suction mechanism 137 is rotatable relative to the first film suction mechanism 136 to move the protective film 301 above a set surface. Thus, the first film suction mechanism 136 and the second film suction mechanism 137 cooperate to fix the protective film 301 before laminating, so that the release liner on the protective film 301 can be removed. The removal of the release liner can be done manually or by another robotic arm. Since the first suction film mechanism 136 and the second suction film mechanism 137 respectively adsorb different parts of the protective film 301, when the second suction film mechanism 137 rotates relative to the first suction film mechanism 136, a part of the protective film 301 will no longer be adsorbed. In this way, when the protective film 301 moves above the set surface, the first roller 123 or the second roller 154 and the third roller 155 can be used to gradually roll the protective film 301 onto the set surface.

[0135] Combination Figure 13 and Figure 14 As shown, in some embodiments, the first film suction mechanism 136 includes a first film suction plate 138 and a first positioning block 139. The first film suction plate 138 has a plurality of negative pressure through holes 140. At least one side of the first film suction plate 138 is fixed with the first positioning block 139. In this way, the first positioning block 139 can be used to position the protective film 301 adsorbed on the first film suction plate 138, which helps to improve the accuracy of the protective film 301 being attached to the electronic device 201. For example, the first suction plate 138 is fixed to the frame 111. The multiple negative pressure holes on the first suction plate 138 can be arranged in an array. The negative pressure holes 140 can be circular or square, and the number of negative pressure holes 140 can be determined according to actual conditions. The negative pressure holes 140 can be connected to a negative pressure device, such as a vacuum pump, to achieve the adsorption of the protective film 301 onto the first suction plate 138. Three sides of the first suction plate 138 are respectively fixed with first positioning blocks 139, which can position the three sides of the protective film 301. The first positioning blocks 139 can be fixed to the first suction plate 138 with screws. In some possible embodiments, the first positioning blocks 139 can be installed on the first suction plate 138 in an adjustable manner, which facilitates the application of protective films 301 of different sizes.

[0136] Combination Figure 13 and Figure 14As shown, in some embodiments, the second film suction mechanism 137 includes a second film suction plate 141, a second positioning block 142, and a first driving mechanism 143; the second film suction plate 141 has a plurality of negative pressure through holes 140; at least one side of the second film suction plate 141 is fixed with the second positioning block 142; the first driving mechanism 143 is used to enable the second film suction plate 141 to rotate relative to the first film suction plate 138 about a first axis. Thus, the second positioning block 142 can be used to position the protective film 301 adsorbed on the second film suction plate 141, which helps to improve the accuracy of the protective film 301 being attached to the electronic device 201. For example, the second suction plate 141 is rotatable relative to the frame 111. Two positioning blocks 142 are fixed to three sides of the second suction plate 141, thus positioning the three sides of the protective film 301. The multiple negative pressure holes 140 on the second suction plate 141 can also be arranged in an array. The negative pressure holes 140 can be circular or square, and the number of negative pressure holes 140 can be determined according to actual conditions. The negative pressure holes 140 can be connected to a negative pressure device, such as a vacuum pump, thereby adsorbing the protective film 301 onto the second suction plate 141. The second positioning blocks 142 can be fixed to the second suction plate 141 by screws.

[0137] In some possible implementations, the second positioning block 142 can be mounted on the second film suction plate 141 in an adjustable manner, which facilitates the application of protective films 301 of different sizes. One side of the second film suction plate 141 is fixedly connected to a rotating shaft 144, which is mounted on the frame 111 via a bearing seat. The first drive mechanism 143 is a motor, and the motor and the rotating shaft 144 are driven by a synchronous belt or gear to realize the rotation of the second film suction plate 141 relative to the first film suction plate 138; and the first axis is the axis of the rotating shaft 144.

[0138] See Figure 13 As shown, in some embodiments, the surface of the first suction plate 138 is parallel to the surface of the second suction plate 141, i.e., they are flush. In this way, the first suction plate 138 and the second suction plate 141 can adsorb the same protective film 301, so as to facilitate the removal of the release film on the protective film 301.

[0139] See Figure 14As shown, in some embodiments, a first limiting plate 145 is also fixed on the frame 111. The first limiting plate 145 limits the rotation of the second suction plate 141. When the second suction plate 141 contacts the first limiting plate 145, the surface of the first suction plate 138 is flush with the surface of the second suction plate 141. When the release film is torn off, the first suction plate 138 no longer adsorbs the protective film 301, while the second suction plate 141 still adsorbs the protective film 301. Then, the first driving mechanism 143 drives the second suction plate 141 to rotate relative to the first suction plate 138, so as to move the protective film 301 above the electronic device 201, thereby facilitating the use of the film support mechanism 113 to support one side of the protective film 301.

[0140] Figure 15 This is a schematic diagram of the edge pressing mechanism 146 in an embodiment of this application; see also Figure 15 As shown, in some embodiments, the film application device further includes an edge pressing mechanism 146, which is movable to a designated surface to press the protective film 301 (see also...) onto the designated surface. Figure 5 The edges of the protective film 301 (as shown) are rolled. This edge-pressing mechanism 146 rolls the edges of the protective film 301, squeezing out air bubbles between the protective film 301 and the screen to ensure surface flatness, increase the adhesion between the protective film 301 and the designated surface, and make the edges of the protective film 301 smoother, eliminating wrinkles and irregular shapes. It should be noted that when rolling the protective film 301 using the edge-pressing mechanism 146, the first roller 123 needs to be raised to move away from the protective film 301 to facilitate the rolling process.

[0141] See Figure 15As shown, in some embodiments, the edge pressing mechanism 146 includes an edge roller 147 and a first spatial moving device. The first spatial moving device is used to drive the edge roller 147 to move to the edge of the protective film 301. The edge roller 147 is used to roll the edge of the protective film 301, thus making the edge of the protective film 301 smoother and eliminating wrinkles and irregular shapes. The edge pressing mechanism 146 also includes a swing bracket 148 and a third bracket 149. The swing bracket 148 is rotatably mounted on the third bracket 149, and the edge roller 147 is rotatably mounted on the swing bracket 148. The rotation axis 144 of the swing bracket 148 is parallel to a first direction, and the rotation axis 144 of the edge roller 147 is also parallel to the first direction. For example, one end of the swing bracket 148 is mounted on the third bracket 149 via a hinge shaft 151. The first spatial movement device includes a fourth linear movement device 150 and a linear drive mechanism 131. The fourth linear movement device 150 is used to move the third support 149 along a second direction, and the linear drive mechanism 131 is used to move the third support 149 along a first direction; the first direction is parallel to the axial direction of the edge roller 147. The fourth linear movement device 150 is a cylinder, hydraulic cylinder, electric cylinder, or pneumatic slide. The third support 149 is a rectangular frame. For example, taking the fourth linear moving device 150 as a cylinder, the edge pressing mechanism 146 further includes a second mounting plate 152. The cylinder body of the fourth linear moving device 150 is fixed to the second mounting plate 152, and the piston rod of the fourth linear moving device 150 is fixedly connected to the third support 149. A linear slide rail 110 is provided between the third support 149 and the second mounting plate 152. The third support 149 is fixedly connected to the slider of the linear slide rail 110, and the second mounting plate 152 is fixedly connected to the guide rail of the linear slide rail 110. The smooth lifting and lowering movement of the third support 149 is achieved through the linear slide rail 110. The second mounting plate 152 is fixedly connected to the slider of the linear drive mechanism 131, and the slide rail of the linear drive mechanism 131 is fixedly connected to the frame 111.

[0142] Figure 16 This is a schematic diagram of the swing bracket 148 in its initial state relative to the third bracket 149 in an embodiment of this application; Figure 17 This is a diagram showing the state of the swing bracket 148 relative to the third bracket 149 after it has swung at a certain angle in this embodiment of the application; combined with Figure 16 and Figure 17As shown, the edge pressing mechanism 146 also includes a linear slide rail 110. The other end of the swing bracket 148 is hinged to the slider of the linear slide rail 110. The guide rail of the linear slide rail 110 is fixedly connected to the third bracket 149, and the other end of the swing bracket 148 is located above one end of the swing bracket 148. The linear slide rail 110 is located above the hinge shaft 151. By setting the linear slide rail 110, when the swing bracket 148 swings relative to the third bracket 149, the swing bracket 148 drives the linear slide rail 110... The slider slides relative to the guide rail of the linear slide rail 110, which can also limit the swing angle of the swing bracket 148 and ensure the stability of the swing bracket 148's swing. To ensure that the swing bracket 148 returns to its initial state after swinging a certain angle, a tension spring can be installed between the slider and the guide rail of the linear slide rail 110 for return, or a tension spring or torsion spring can be installed at the hinge shaft 151 where the swing bracket 148 connects to the third bracket 149. The film-applying device provided in this application embodiment is not limited to applying the protective film 301 to a display screen with decorative elements 202; it can also apply film to displays on electronic devices 201 without decorative elements 202. It can apply film not only to 2D displays but also to 2.5D and 3D displays. It should be noted that... Figure 16 and Figure 17 Only the electronic device 201 and the protective film 301 are shown, while the support mechanism 100 is not shown.

[0143] Combination Figure 16 and Figure 17 As shown, when rolling the edge of the protective film 301, the linear drive mechanism 131 drives the third support 149 to move along the first direction, causing the edge roller 147 to move above the protective film 301 on the electronic device 201; then the fourth linear moving device 150 drives the third support 149 to move along the second direction, causing the third support 149 to move downwards. When the edge roller 147 contacts the protective film 301, the edge roller 147 is subjected to force, causing the swing support 148 to swing relative to the third support 149 at a certain angle, that is, the swing support 148 swings from... Figure 16 The state in becomes Figure 17 The protective film 301 is rolled against the edge of the screen of the electronic device 201. Then the fourth linear moving device 150 moves upward, and after the swing bracket 148 returns to its original position, the fourth linear moving device 150 moves downward again, repeating the above process so that the edge of the protective film 301 fits against the display screen of the electronic device 201.

[0144] Figure 18 This is a schematic diagram of the overall structure of the film application device in an embodiment of this application; see also Figure 18As shown, in some embodiments, the film-applying equipment also includes a housing, with the frame 111 fixedly connected to the housing. The housing facilitates protection of different mechanisms within the film-applying equipment and improves the dust-free environment during the application process. The film-applying equipment also includes a control device 153, which can be a computer, a PLC (Programmable Logic Controller), or a single-chip microcomputer. The control device 153 controls various mechanisms of the film-applying equipment, such as the support mechanism 100 and the film-applying mechanism 105. The film-applying equipment provided in this application embodiment can be used to apply protective films 301 of different materials. For example, the protective film 301 can be made of PET (Polyethylene terephthalate), TPU (Thermoplastic polyurethanes), or UV (Ultraviolet) curable film, etc.

[0145] In one or more embodiments, this application also provides a film application method using the film application device in any of the above embodiments; the film application method includes: detachably fixing an electronic device 201 having a decorative element 202 to a support mechanism 100; covering the surface of the electronic device 201 having the decorative element 202 with a protective film 301 by a film application mechanism 105, and during the film application process of the film application mechanism 105, the avoidance structure of the film application mechanism 105 can avoid the decorative element 202.

[0146] Figure 19 This is a diagram showing the state of the electronic device 201 being adsorbed onto the support plate 101 in an embodiment of this application. In some embodiments, the method for detachably fixing the electronic device 201 with decorative parts 202 onto the support plate 101 includes: adsorbing the electronic device 201 onto the support plate 101 of the support mechanism 100; and using the first linear movement device 115 of the support mechanism 100 to make the edge block 108 move linearly, so that the edge block 108 moves to the side of the electronic device 201. Specifically, the vacuum suction cup 107 of the adsorption assembly 102 (see...) Figure 3 As shown, the electronic device 201 on the support plate 101 is adsorbed; after the first linear moving device 115 moves the edge block 108 a certain distance, the edge block 108 is positioned on the side of the electronic device 201 to limit the side of the electronic device 201, which can reduce the movement of the electronic device 201 during the film application process.

[0147] Figure 20 This is a diagram showing the state of the protective film 301 being adsorbed onto the first film suction mechanism 136 and the second film suction mechanism 137 in an embodiment of this application. Figure 21This is a state diagram of the protective film 301 when it is adsorbed by the second film suction mechanism 137 in an embodiment of this application; in some embodiments, the method of covering the protective film 301 onto the surface of the electronic device 201 with the decorative element 202 by the film covering mechanism 105 includes: see Figure 20 As shown, when the first suction plate 138 of the first suction mechanism 136 and the second suction plate 141 of the second suction mechanism 137 are aligned, the first suction mechanism 136 and the second suction mechanism 137 simultaneously adsorb the protective film 301, and then remove the release film on the protective film 301. After the release film is removed, the first suction plate 138 of the first suction mechanism 136 no longer adsorbs the protective film 301, while the second suction plate of the second suction mechanism 137 still adsorbs the protective film 301. Then, the first drive mechanism 143 rotates the second suction plate 141 by a certain angle, so that the protective film 301 is positioned above the electronic device 201, as shown. Figure 21 As shown, the protective film 301 is located above the electronic device 201 and is still adsorbed by the second suction plate 141.

[0148] Figure 22 This is a diagram showing the state of the protective film 301 being supported by the film-supporting mechanism 113 in an embodiment of this application; see also Figure 22 As shown, in some embodiments, the method of covering the protective film 301 onto the surface of the electronic device 201 with the decorative element 202 by the film-coating mechanism 105 further includes: after the second film-suction mechanism 137 rotates at a certain angle relative to the first film-suction mechanism 136, so that the protective film 301 is positioned above the electronic device 201, the film-suction plate of the second film-suction mechanism 137 releases the protective film 301, so that one side of the protective film 301 is supported by the first support block 114 of the film-supporting mechanism 113, while the opposite side of the protective film 301 contacts the electronic device 201; then the second spatial moving device moves the first support 127 along the first direction and moves the first support 127 along the second direction, so that the first roller 123 contacts the protective film 301 to begin rolling the protective film 301. It should be noted that... Figure 20 , Figure 21 and Figure 22 In order to illustrate the outline of electronic device 201, therefore Figure 20 , Figure 21 and Figure 22 The middle edge block 108 was not raised. During the normal lamination process, the edge block 108 needs to be raised to the edge of the electronic device 201.

[0149] Please return Figure 5As shown, in some embodiments, during the film-coating process of the film-coating mechanism 105, the avoidance structure of the film-coating mechanism 105 can avoid the decorative element 202, including: rolling the first roller 123 of the film-coating mechanism 105 on the surface with the decorative element 202, wherein the groove structure 124 on the first roller 123 can accommodate the decorative element 202. That is, when the second spatial moving device makes the first roller 123 contact the protective film 301, the first roller 123 moves in the second direction, gradually moving from the other side of the protective film 301 to one side of the protective film 301, that is, the first roller 123 moves in the direction of the film-supporting mechanism 113. During the movement, the decorative element 202 enters the groove structure 124, thereby achieving avoidance and protecting the decorative element 202. When the first roller 123 moves from the other side of the protective film 301 to one side of the protective film 301, one rolling of the protective film 301 is completed. The movement of the first roller 123 in the first direction is achieved by the linear drive mechanism 131.

[0150] Figure 23 This is a schematic diagram of the coating mechanism 105 using a second roller 154 and a third roller 155 to roll the protective film 301 in an embodiment of this application. Figure 24 This is another schematic diagram of the coating mechanism 105 using the second roller 154 and the third roller 155 to roll the protective film 301 in an embodiment of this application; see also Figure 23 and Figure 24 As shown, in some embodiments, the film coating mechanism 105 includes a second roller 154 and a third roller 155; the second roller 154 and the third roller 155 respectively roll different areas of the set surface, and the areas rolled by the second roller 154 and the third roller 155 respectively avoid the decorative element 202; the avoidance structure includes the second roller 154 and the third roller 155, so that the second roller 154 and the third roller 155 alternately roll different areas of the protective film 301 around the decorative element 202, and since the second roller 154 and the third roller 155 have different lengths, they can avoid the decorative element 202, thereby achieving protection of the decorative element 202 during the film application process.

[0151] It should be noted that in some other possible implementations, the rolling of the protective film 301 on the set surface is not limited to the second roller 154 and the third roller 155, but also uses more rollers to cooperate in order to achieve rolling of the protective film.

[0152] In some embodiments, the axial direction of the second roller 154 is parallel to the axial direction of the third roller 155. This enables the second roller 154 and the third roller 155 to work simultaneously, or facilitates the simplification of the design of the film application equipment; the axial directions of the second roller 154 and the third roller 155 are respectively parallel to the third direction, and the second roller 154 and the third roller 155 are spaced apart in the first direction.

[0153] In some embodiments, such as Figure 23 As shown, the lengths of the second roller 154 and the third roller 155 in the third direction are both less than the width of the protective film 301, and the length of the third roller 155 in the third direction is greater than the length of the second roller 154 in the third direction. The sum of the lengths of the second roller 154 and the third roller 155 in the third direction can be equal to the width of the protective film 301, so that the second roller 154 and the third roller 155 cooperate to roll the protective film 301.

[0154] In other embodiments, such as Figure 24 As shown, the sum of the lengths of the second roller 154 and the third roller 155 in the third direction is greater than the width of the protective film 301. The length of the second roller 154 in the third direction is greater than the length of the third roller 155 in the third direction, so that the second roller 154 and the third roller 155 cooperate to roll the protective film 301. The lengths of the second roller 154 and the third roller 155 in the third direction can also be referred to as their respective axial lengths; the length of the second roller 154 in the third direction can also be equal to or greater than the length of the protective film 301; the length of the third roller 155 in the third direction is less than the width of the protective film 301.

[0155] It should be noted that the second roller 154 and the third roller 155 can be mounted on the same mounting bracket, which can be driven in a manner opposite to the first bracket 127 to achieve movement in both the first and second directions. The rotation of the second roller 154 and the third roller 155 can be achieved by a linear drive mechanism 131, i.e., the second roller 154 and the third roller 155 respectively achieve rotation through friction with the protective film 301; alternatively, at least one of the second roller 154 and the third roller 155 can be driven by a motor to achieve its own rotation.

[0156] In one or more embodiments, this application also provides another film application method using a film application device with a second roller 154 and a third roller 155; this film application method differs from the film application method using a film application device with a first roller 123 only in that different rollers are used; other steps are the same as the film application method using a film application device with a first roller 123, and will not be described in detail. During the film application process of the film application mechanism 105, the avoidance structure of the film application mechanism 105 can avoid the decorative element 202, including: rolling different areas of the surface of the decorative element 202 by the second roller 154 and the third roller 155 of the film application mechanism 105 respectively, wherein the areas rolled by the second roller 154 and the third roller 155 respectively avoid the decorative element 202. Specifically, the linear drive mechanism 131 drives the mounting bracket to move along the first direction, and the mounting bracket is driven by the linear moving device to realize the lifting and lowering of the mounting bracket so that the second roller 154 and the third roller 155 can contact the protective film 301. After the second roller 154 and the third roller 155 can contact the protective film 301, the linear drive mechanism 131 continues to move along the first direction to realize the second roller 154 and the third roller 155 rolling the protective film 301.

[0157] Figure 25 This is a schematic diagram of the structure of the suction plate 156 covering the protective film 301 onto the electronic device 201 in an embodiment of this application; see also Figure 25 As shown, in some embodiments, the laminating mechanism 105 includes a film-absorbing plate 156 for adsorbing the protective film 301 and covering it onto a designated surface. The film-absorbing plate 156 has a clearance hole 161 for accommodating the decorative element 202, and the clearance structure includes the clearance hole 161. Thus, the film-absorbing plate 156 can cover the designated surface by either having the protective film 301 parallel to the designated surface or by rotating the film-absorbing plate 156. The diameter of the clearance hole 161 is larger than the diameter of the decorative element 202, thus preventing the film-absorbing plate 156 from damaging the decorative element 202. The side of the film-absorbing plate 156 that adsorbs the protective film 301 can be similar in shape to the designated surface, thereby improving the flatness of the adhesion.

[0158] It should be noted that, Figure 25 The coating method shown is the same as Figure 2 , Figure 23 and Figure 24 The difference in the coating methods is that, Figure 24The first film suction mechanism 136 and the second film suction mechanism 137 can be omitted. After the electronic device 201 is placed on the support mechanism 100, the protective film 301 is adsorbed onto the film suction plate 156. After the release film is torn off, the film suction plate 156 can cover the protective film 301 on the set surface of the electronic device 201 by moving along the second direction, i.e., by lifting or lowering, or by rotating around an axis parallel to the first direction. The lifting and lowering of the film suction plate 156 can be achieved by using a linear moving device, such as a cylinder, hydraulic cylinder, electric cylinder or pneumatic slide, while the rotation of the film suction plate 156 around an axis parallel to the first direction can be achieved by driving the film suction plate 156 to rotate by a motor.

[0159] Figure 26 This is a schematic diagram of the degassing device 157 degassing the protective film 301 in an embodiment of this application. Figure 27 This is a schematic diagram of the degassing device 157 in the embodiments of this application; combined with Figure 26 and Figure 27 As shown, in some embodiments, the coating mechanism 105 further includes a degassing device 157, which is a device that uses compressed gas to achieve degassing. The degassing device 157 is used to remove air bubbles between the protective film 301 and the set surface by applying compressed gas to the protective film 301 attached to the set surface. After the protective film is covered on the set surface by the suction plate 156, the degassing device 157 removes the air bubbles formed during the film application process. The degassing device 157 includes a pressure plate 158 and a compressed air source (not shown). The pressure plate 158 has multiple different air outlet areas 159, and each annular area has multiple air outlet holes 160. The air outlet holes 160 in each air outlet area 159 are connected to the compressed air source. The compressed gas source can provide gas at different pressures to different outlet regions 159, which facilitates the rapid removal of air bubbles between the protective film 301 and the electronic device 201. For example, the pressure of the compressed gas gradually decreases from the innermost outlet region 159 to the outermost outlet region 159. The innermost outlet region 159 can be rectangular, circular, or other shapes, while the remaining outlet regions 159 are annular. The pressure of the gas ejected from the outlet holes 160 in each outlet region 159 is the same.

[0160] It should be noted that the degassing device 157 can be moved to the protective film 301 by rotation or linear movement to facilitate degassing; the rotation of the degassing device 157 can be driven by a motor, and the linear movement can be achieved by a linear device, such as a cylinder, hydraulic cylinder, electric cylinder or pneumatic slide.

[0161] Combination Figure 26 and Figure 27As shown, in one or more embodiments, this application also provides another film application method using a film application device having a suction plate 156 and a debubbling device 157; the film application method includes: detachably fixing an electronic device 201 with a decorative element 202 to a support mechanism 100; covering the surface of the electronic device 201 with the decorative element 202 of the electronic device 201 with a protective film 301 by a film application mechanism 105, and during the film application process of the film application mechanism 105, the avoidance structure of the film application mechanism 105 can avoid the decorative element 202. Specifically, the electronic device 201 is adsorbed onto the support plate 101, the protective film 301 is adsorbed onto the film suction plate 156, and the release film is removed. Then, the film suction plate 156 covers the protective film 301 onto the set surface. During the film coating process of the film coating mechanism 105, the decorative piece 202 is inserted into the clearance hole 161 on the film suction plate 156 of the film coating mechanism 105 so that the protective film 301 covers the surface with the decorative piece 202. Then, the film suction plate 156 releases the protective film 301 and no longer adsorbs the protective film 301. After the film suction plate 156 releases the protective film 301, it is removed from the electronic device 201. The degassing device 157 is moved to the protective film 301. The degassing device 157 of the film coating mechanism 105 uses compressed gas to act on the protective film 301 attached to the set surface to remove air bubbles between the protective film 301 and the set surface.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
