[0028] In order to make the purpose, technical solution and advantages of the present disclosure more clear, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the present disclosure and do not limit the protection scope of the present disclosure.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0030] Electronic devices such as mobile phones and tablets have become indispensable technology products in people's lives, learning and entertainment. At present, electronic devices using foldable screens have variable screen sizes, which are convenient for users to switch between large and small screens according to actual needs, which can improve user experience and are increasingly favored by consumers.

[0031] When using electronic devices, people often put a protective film on the outside of the screen to protect the screen. However, in the related art, since the folding screen has different degrees of grooves on the screen in the folding area, the failure rate of putting a protective film on the folding screen is high, which increases the cost of putting the film on, which is not conducive to improving the user experience.

[0032] Based on this, the present disclosure provides a film scraping mechanism, a film pasting device and a film pasting method, which can improve the success rate of film pasting on a folding screen and help reduce the cost of film pasting on the folding screen.

[0033] The technical solution of the present disclosure is described below with reference to the accompanying drawings.

[0034] like Figure 1 The figure is a schematic diagram of the structure of the scraping mechanism. In the embodiment of the present disclosure, a scraping mechanism 100 is provided, including a supporting assembly 110 and a scraping assembly 120; the supporting assembly 110 includes a supporting portion 101 and a mounting portion 102 arranged above the supporting portion 101; the scraping assembly 120 is arranged on the supporting assembly 110 through the mounting portion 102, and the scraping assembly 120 includes a scraping member 121 that can move up and down relative to the mounting portion 102, and the scraping member 121 includes a pressing portion 103 in the shape of a strip, and the pressing portion 103 is arranged away from the mounting portion 102, and the pressing portion 103 can press the protective film 30 in the groove 22 of the film sticking area 21.

[0035] When the film scraping mechanism 100 is applied to film pasting, the protective film 30 is set in the film pasting area 21 of the film pasting device 20 to be pasted, and the film scraping member 121 moves to the top of the protective film 30, so that the pressing part 103 presses the protective film 30 and the film pasting area 21, and the protective film 30 is pressed and fixed in the film pasting area 21 by the pressing part 103. When the pressing part 103 passes through the groove 22 of the film pasting area 21, the pressing part 103 presses the protective film 30 through the scraping member 121 that can move up and down, so that the pressing part 103 can adjust the position according to the depth of the groove 22, and then the protective film 30 can also be squeezed by the pressing part 103 in the groove 22 of the film pasting area 21 and fixed in the film pasting area 21. In this way, when the film scraping mechanism 100 is applied to the film pasting of the folding screen, the success rate of film pasting on the folding screen can be improved, which is conducive to reducing the film pasting cost of the folding screen.

[0036] It should be noted that the film-applying area 21 includes areas where film needs to be applied, such as the surface of the folding screen, the curved screen, and the outer shell.

[0037] In addition, the protective film 30 includes tempered films, soft films, curved films and other protective films 30 , which can be specifically selected according to the characteristics of the film-applying area 21 .

[0038] In some embodiments, the pressing portion 103 is provided with a soft contact surface 104 for contacting the protective film 30. Thus, the soft contact surface 104 can avoid rigid contact between the pressing portion 103 and the protective film 30, so that the pressing portion 103 can more safely and reliably press the protective film 30 to the film attachment area 21.

[0039] Furthermore, in some embodiments, the film scraper 121 further includes an elastic layer disposed outside the pressing portion 103, and the elastic layer is used to form the soft contact surface 104. In this way, the soft contact surface 104 is formed by an elastic layer such as rubber or foam, which is easy to implement and convenient to fix on the pressing portion 103.

[0040] Based on any of the above embodiments, in some embodiments, the cross section of the pressing portion 103 is tapered on the orthographic projection plane perpendicular to the length direction of the pressing portion 103. In this way, the pressing portion 103 can better enter and exit the groove 22 of the film sticking area 21, and fix the protective film 30 in the groove 22 as free of bubbles as possible.

[0041] Optionally, in some embodiments, the pressing part 103 is a roller or a rolling belt. In this way, the pressing part 103 can roll and rub against the protective film 30 by using the roller and the rolling belt, so as to press the protective film 30 and move smoothly on the protective film 30, thereby improving the film application efficiency.

[0042] In some embodiments, the support assembly 110 includes a support member 111 and a mounting member 112 fixedly connected to one end of the support member 111, the other end of the support member 111 is provided with a support portion 101, and the mounting member 112 is provided with a mounting portion 102. In this way, through the cooperation between the support member 111 and the mounting member 112, it is convenient to set the mounting portion 102 above the support portion 101, and then the film scraping member 121 can be set above the support portion 101, so that the pressing portion 103 presses the protective film 30 and the film pasting area 21 from top to bottom, which is convenient for film pasting processing and improves the film pasting efficiency.

[0043] Optionally, in some embodiments, the support member 111 includes two, which are respectively located at both ends of the mounting member 112, and the film scraping assembly 120 is disposed between the two support members 111. In this way, the two support members 111 cooperate with the mounting member 112 to form a gantry structure, which facilitates the installation of the film scraping assembly 120, makes the force of the film scraping member 121 more uniform, and improves the reliability of the film scraping mechanism 100.

[0044] It should be noted that the "mounting member 112" can be one of the parts of the module "support assembly 110", that is, it can be assembled into a module with the "other components of the support assembly 110" and then assembled modularly; it can also be relatively independent of the "other components of the support assembly 110" and can be installed separately, that is, it can form a whole with the "other components of the support assembly 110" in this device.

[0045] Equivalently, the components included in the "unit", "assembly", "mechanism" and "device" of the present disclosure can also be flexibly combined, that is, modular production can be carried out according to actual conditions, modular assembly can be carried out as an independent module; or they can be assembled separately to form a module in the present device. The division of the above components in the present disclosure is only one embodiment, for the convenience of reading, and not to limit the scope of protection of the present disclosure. As long as the above components are included and have the same functions, it should be understood that it is an equivalent technical solution of the present disclosure.

[0046] It should be noted that there are many ways for the film scraper 121 to move up and down relative to the mounting portion 102. For example, it can be driven by a telescopic mechanism, including but not limited to a telescopic rod, a telescopic plate, a telescopic rod, a pneumatic rod, a hydraulic rod, a linear motor and other direct-driven power equipment, and also includes a mechanism that indirectly realizes the reciprocating movement of the supporting member by using a gear rack mechanism, a screw nut mechanism and the like.

[0047] Alternatively, in some embodiments, the film scraping assembly 120 further includes an elastic expansion unit 122, which is connected to the film scraping member 121 so that the film scraping member 121 is elastically reset relative to the mounting portion 102. In this way, the film scraping assembly 120 can automatically move up and down according to the changes in the film pasting area 21 by using the elastic expansion unit 122, so that the pressing portion 103 can reliably press the protective film 30 and fix the protective film 30 on the film pasting area 21.

[0048] The elastic telescopic unit 122 can be realized by using the elastic member 108 in cooperation with a telescopic mechanism, or can be realized by using other telescopic structures in cooperation with the elastic member 108 .

[0049] For example, in some embodiments, the elastic telescopic unit 122 includes a sliding member 105, a first baffle 106, a second baffle 107, and an elastic member 108. The sliding member 105 is telescopically connected to the mounting portion 102, and one end of the sliding member 105 passes through the first baffle 106 and the second baffle 107 in sequence, and is connected to the film scraping member 121. The first baffle 106 is fixed to the support assembly 110 through the mounting portion 102, and the second baffle 107 can be telescopically moved relative to the first baffle 106 through the sliding member 105. The elastic member 108 is disposed between the first baffle 106 and the second baffle 107. In this way, when applying film to the folding screen, the film scraping member 121 can move up and down along the length direction of the sliding member 105 through the sliding member 105. In the process of the pressing portion 103 of the film scraping member 121 abutting against the protective film 30, the elastic member 108 can be used to provide an elastic pressing force to press the protective film 30 to the film application area 21. When the pressing part 103 moves from the plane area of ​​the folding screen to the surface area of ​​the groove 22, the restoring force of the elastic member 108 is used to drive the pressing part 103 to move downward, and then the pressing part 103 can be moved downward and continue to press the protective film 30 on the surface of the groove 22. When moving from the surface area of ​​the groove 22 to the plane area, the pressing part 103 moves upward with the sliding member 105, and the elastic member 108 can be compressed so that the pressing part 103 continues to press the protective film 30 on another plane area, and finally the film of the folding screen is completed.

[0050] The groove 22 of the folding screen generally refers to the folding part of the screen.

[0051] like Figure 2 and Figure 3 , which is a structural view of the film sticking device 10 shown in some embodiments. Figure 2 For application Figure 1 A structural schematic diagram of a film sticking device 10 of a film scraping mechanism 100 is shown. Figure 3 For application Figure 1 Another structural schematic diagram of the film sticking device 10 of the film scraping mechanism 100 is shown.

[0052] like Figure 1 and Figure 2 As shown, in an embodiment of the present disclosure, a film pasting device 10 is also provided, including a base 200 and a film scraping mechanism 100 in any of the above embodiments, the base 200 is provided with a fixing portion 210 for fixing the device 20 to be pasted, and the film scraping mechanism 100 and the fixing portion 210 can move relative to each other.

[0053] When the film is used, the device 20 to be film-applied is fixed on the base 200 through the fixing part 210, so that the film-applied area 21 of the device 20 to be film-applied is set upward, the protective film 30 is set on the film-applied area 21, and the film scraping member 121 moves to the top of the protective film 30, so that the pressing part 103 presses the protective film 30 and the film-applied area 21, and the protective film 30 is pressed and fixed on the film-applied area 21 through the pressing part 103. When the pressing part 103 passes through the groove 22 of the film-applied area 21, the pressing part 103 presses the protective film 30 through the scraping part 121 that can move up and down, so that the pressing part 103 can adjust the position according to the depth of the groove 22, and then the protective film 30 can also be squeezed by the pressing part 103 in the groove 22 of the film-applied area 21 and fixed on the film-applied area 21. In this way, when the film-applied device 10 is applied to the film-applied of a folding screen, the success rate of film-applied on the folding screen can be improved, which is conducive to reducing the film-applied cost of the folding screen.

[0054] It should be noted that the fixing portion 210 can be flexibly selected according to the characteristics of the device 20 to be film-mounted, including but not limited to a tooling fixture, a limiting groove 22 and the like.

[0055] In some embodiments, the support portion 101 can be slidably disposed on the base 200 so that the film scraping member 121 can reciprocate relative to the fixing portion 210. In this way, when film is applied, the pressing portion 103 is used to press the protective film 30 against the device 20 to be applied fixed on the fixing portion 210, and the film scraping member 121 can move smoothly along the base 200, so that the pressing portion 103 can smoothly fix the protective film 30 on the film application area 21.

[0056] Optionally, in some embodiments, the film scraping mechanism 100 includes two, and each of them can be slidably arranged on the base 200 through the support part 101; the soft contact surfaces 104 of the two film scraping mechanisms 100 can be arranged in contact with each other. In this way, the two film scraping mechanisms 100 can be used to press and apply the film from two directions at the same time, which is conducive to improving the film application efficiency. For example, the two pressing parts 103 are arranged in the middle of the film application area 21 (or the groove 22) of the film application device 20 to be applied, and then the two pressing parts 103 are moved back to back to apply the film.

[0057] Furthermore, in some embodiments, on the orthographic projection plane perpendicular to the length direction of the pressing portion 103, the cross section of the pressing portion 103 is in the shape of a right triangle, so that the two pressing portions 103 can be arranged in close contact. In this way, the two pressing portions 103 are closely attached, and when the two pressing portions 103 are arranged in the initial pressing area of ​​the film pasting area 21 of the film pasting device 20, the protective film 30 can be better pressed and fixed in the film pasting area 21, and then the two pressing portions 103 are moved back to back for film pasting, thereby improving the film pasting quality.

[0058] Optionally, in some embodiments, the base 200 is provided with a positioning mark 220, and the positioning mark 220 is in the same straight line as the center line of the length direction of the fixing portion 210. In this way, the positioning mark 220 is used to facilitate alignment adjustment, so that the two pressing portions 103 can be aligned and fitted at the positioning mark 220, so that the film can be scraped from the center of the film pasting area 21 to both ends, and the protective film 30 can be accurately fixed on the film pasting area 21, thereby improving the success rate of film pasting.

[0059] like Figure 1 and Figure 3 As shown, based on any of the above embodiments of the film pasting device 10, in some embodiments, the film pasting device 10 further includes a film body bearing mechanism 300, which can be moved relative to the fixed portion 210, and the film body bearing mechanism 300 includes a film body bearing platform 310. In this way, the protective film 30 can be placed on the film body bearing platform 310, and then the film body bearing mechanism 300 is moved to move the protective film 30 above the fixed portion 210, so as to cover the protective film 30 on the film pasting area 21. Finally, the film body bearing mechanism 300 is removed, the film scraping mechanism 100 is moved to a suitable position, and the pressing portion 103 is used to press the protective film 30 to perform the film pasting work. In addition, the film body bearing mechanism 300 is used to facilitate the transfer of the protective film 30, thereby reducing the possibility of the protective film 30 being contaminated.

[0060] Optionally, in some embodiments, the film body supporting platform 310 is provided with negative pressure suction holes, which can better fix the protective film 30 on the film body supporting platform 310 without damaging the protective film 30, thereby improving the reliability and success rate of film pasting.

[0061] Furthermore, in some embodiments, the film bearing mechanism 300 further includes a telescopic component 320, which can be slidably disposed on the base 200, and the telescopic component 320 is connected to the film bearing platform 310, so that the height between the film bearing platform 310 and the fixing part 210 can be adjusted. In this way, the telescopic component 320 can be used to more flexibly adjust the height spacing between the film bearing platform 310 and the fixing part 210, and then can be flexibly adjusted according to the characteristics of the device 20 to be film-mounted, thereby improving the adaptability of the film-mounting device 10.

[0062] The telescopic assembly 320 includes but is not limited to directly driven power equipment such as telescopic sticks, telescopic plates, telescopic rods, pneumatic rods, hydraulic rods, linear motors, etc., and also includes mechanisms that indirectly realize the reciprocating movement of the supporting parts using gear rack mechanisms, screw nut mechanisms, etc.

[0063] Specifically, the telescopic assembly 320 is a hand-cranked telescopic assembly 320 , which realizes sliding through the cooperation of the gear and the rack, and utilizes the hand crank 321 to drive the gear to rotate, thereby realizing the up and down movement of the membrane supporting platform 310 .

[0064] In addition, there are many specific implementations of the film scraping mechanism 100 being slidably disposed on the base 200 and the film body bearing mechanism 300 being slidably disposed on the base 200, such as using a slide rail assembly; or the two cooperate to form a slide rail structure, for example, the base 200 is provided with a guide rail 400, and the support portion 101 is provided with a guide groove that cooperates with the guide rail 400; similarly, the film body bearing mechanism 300 can also be provided with a guide groove. The two can use the same guide rail 400 or different guide rails 400 to achieve sliding.

[0065] In some embodiments, the film pasting device further includes a controller (not labeled), the controller is respectively connected to the film body bearing mechanism and the film scraping mechanism in communication; the controller includes a processor and a memory for storing computer programs, the processor is used to run the computer program stored in the memory to implement the following film pasting method, including: setting the protective film in the film pasting area of ​​the device to be pasted; the two film scraping members move to the top of the protective film, and make the pressing part press the protective film and the film pasting area; the two film scraping members move in opposite directions to fix the protective film to the film pasting area. In this way, the controller can be used to automatically control the movement of the film body bearing mechanism and the film scraping mechanism, improve the degree of automation of film pasting, and improve the efficiency of film pasting. Furthermore, the film pasting process of the protective film can be completed before the electronic device leaves the factory, which can provide users with electronic devices with protective films, reduce the cost of film pasting for users, and improve user experience.

[0066] Of course, the film sticking device can also be used for after-sales or pre-sales services, and the film sticking device can be used to help store operators quickly implement the film sticking process, improve the film sticking efficiency, and reduce user waiting time.

[0067] Optionally, the film laminating device further comprises a driving mechanism, the driving mechanism is used to drive the film body bearing mechanism and the film scraping mechanism to move relative to the base, and the controller is in communication connection with the driving mechanism. Then, the film body bearing mechanism and the film scraping mechanism can be electrically moved relative to the base by controlling the driving mechanism, thereby improving the degree of automation of film laminating and reducing labor intensity.

[0068] The driving mechanism can be arranged according to the movement mode required by the film bearing mechanism and the film scraping mechanism, including a robot operating arm, a telescopic device, a reciprocating moving device, a swing driving device, a conveying device, and the like.

[0069] The communication control means between the controller and each actuator (such as the film scraping mechanism, the film body bearing mechanism) and the feedback element (identification unit) belongs to the traditional technology and will not be described in detail here.

[0070] The "communication connection" can be realized by wired communication technology or wireless communication technology, which is a traditional technology and will not be described in detail here. In addition, the communication connection between the above devices can be a direct communication connection or an indirect communication connection.

[0071] The memory can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, magnetic disk or optical disk, and other media that can store program code.

[0072] The processor can be a micro-controller unit (MCU), a central processing unit (CPU) or a digital signal processor (DSP), etc.

[0073] Optionally, in some embodiments, when the two film scrapers move in opposite directions, the two film scrapers move synchronously, or one of the film scrapers moves first and the other one moves later. In this way, the opposite film pasting method can be flexibly selected according to the characteristics of the film pasting area to ensure the quality of the film pasting.

[0074] In some embodiments, the two film scraping members move to the top of the protective film, and the pressing parts press the protective film and the film pasting area in the initial pressing area. In this way, when the two pressing parts are set in the initial pressing area of ​​the film pasting area of ​​the film pasting device, the two pressing parts are used for double pressing, which can better press the protective film in the film pasting area, and then the two pressing parts are moved back to back to perform film pasting, which can improve the film pasting quality.

[0075] Optionally, in some embodiments, the initial pressing area is the middle of the device to be film-mounted or a groove in the film-mounting area of ​​the device to be film-mounted, thereby ensuring that the protective film is gradually fixed to the film-mounting area from the inside to the outside, improving the film-mounting accuracy and reducing the generation of bubbles.

[0076] In some embodiments, after the protective film is attached to the film attaching area, the device that has completed the film attaching is sent to a degassing device for degassing. In this way, the degassing device can improve the quality of the film attaching, reduce the manual degassing work, further improve the degree of automation of the film attaching, and improve the efficiency of the film attaching.

[0077] Based on any of the above controller embodiments, in some embodiments, after the protective film is attached to the film attaching area, the method further includes: obtaining the film attaching status to determine whether the protective film attached to the film attaching area is abnormal; if the protective film attached to the film attaching area is abnormal, a reminder message is sent. In this way, automatic re-inspection can be performed to promptly remind the operator that the film attaching is unqualified and needs to be re-attached or manually attached.

[0078] The film sticking status includes whether there are bubbles, whether it is aligned, etc., and can be judged by machine vision technology, such as taking photos for comparison and analysis.

[0079] like Figure 4 As shown, in an embodiment of the present disclosure, a film pasting method is also provided, comprising:

[0080] S100 sets the protective film on the film pasting area of ​​the device to be pasted;

[0081] S200: two film scraping parts move to the top of the protective film, and the pressing parts press the protective film and the film sticking area tightly;

[0082] S300 The two film scraping parts move in opposite directions to fix the protective film on the film sticking area.

[0083] The technical solution provided by the embodiments of the present disclosure may have the following beneficial effects:

[0084] When this film pasting method is applied to the film pasting of a folding screen, it can improve the degree of automation of the film pasting, increase the success rate of film pasting on the folding screen, and help reduce the cost of film pasting for the folding screen.

[0085] Optionally, in some embodiments, when the two film scrapers move in opposite directions, the two film scrapers move synchronously, or one of the film scrapers moves first and the other one moves later. In this way, the opposite film pasting method can be flexibly selected according to the characteristics of the film pasting area to ensure the quality of the film pasting.

[0086] In some embodiments, the two film scraping members move to the top of the protective film, and the pressing parts press the protective film and the film pasting area in the initial pressing area. In this way, when the two pressing parts are set in the initial pressing area of ​​the film pasting area of ​​the film pasting device, the two pressing parts are used for double pressing, which can better press the protective film in the film pasting area, and then the two pressing parts are moved back to back to perform film pasting, which can improve the film pasting quality.

[0087] In some embodiments, the initial pressing area is the middle of the device to be filmed or a groove in the film-pasting area of ​​the device to be filmed, thereby ensuring that the protective film is gradually attached to the film-pasting area from the inside to the outside, improving the film-pasting accuracy and reducing the generation of bubbles.

[0088] like Figure 5 As shown, in some embodiments, after the protective film is attached to the film attaching area, the process further includes S400: sending the film attaching device to a degassing device for degassing. In this way, using the degassing device for degassing can improve the film attaching quality, reduce the manual degassing work, further improve the degree of automation of film attaching, and improve the efficiency of film attaching.

[0089] like Figure 5 As shown, in some embodiments, after the protective film is attached to the film attaching area, S500 is also included: obtaining the film attaching status to determine whether the protective film attached to the film attaching area is abnormal; if the protective film attached to the film attaching area is abnormal, a reminder message is sent. In this way, automatic re-inspection can be performed to facilitate timely reminders to operators that the film attaching is unqualified and needs to be re-attached or manually attached. The film attaching status includes whether there are bubbles, whether it is aligned, etc., and can be determined by machine vision technology. For example, taking photos for comparison and analysis.

[0090] In the description of the present disclosure, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present disclosure.

[0091] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0092] In the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0093] In the present disclosure, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0094] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixedly arranged on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Furthermore, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-fitting, integral molding, welding, etc., which can be achieved in traditional technologies and will not be repeated here.

[0095] The technical features of the above embodiments may be combined arbitrarily.
