Description

[Technical Field]

[0001] The present invention relates to the field of film application technology for mobile terminals such as mobile phones and tablets, and more particularly to a film application assistant device, a film application machine, and a film application module. [Background technology]

[0002] In daily life, a film is generally attached to the surface of a smartphone, smart watch, tablet computer, or other device to prevent the screen from being scratched or cracked.

[0003] In order to improve the accuracy of film application in existing technologies, a film application auxiliary device has been developed. It includes a positioning base with a mold groove for receiving an electronic device, a receiving groove at the bottom of the mold groove for placing a protective film, and an opening groove on one side of the positioning base that communicates with the mold groove. When applying a film to an electronic device, the protective film is first placed in the receiving groove of the film application auxiliary device, and the shape of the receiving groove matches the protective film, serving to position it. The electronic device is then placed in the mold groove, and the screen side of the electronic device is pressed against the protective film. Then, by pulling the tab on the protective film, the release film on the protective film is pulled out from the opening groove, thereby achieving automatic application of the protective film.

[0004] In the above-mentioned film application assisting device, the weight of the electronic device causes the screen of the electronic device to adhere closely to the protective film, preventing the formation of sufficient exhaust space between the screen and the protective film, which can easily cause air bubbles during application. In addition, the bottom wall of the accommodating groove adheres closely to the protective film to support it, and if the accommodating groove is deformed, the bottom wall of the accommodating groove becomes uneven, which in turn causes the protective film placed in the accommodating groove to become uneven, which can easily affect the evenness of the film application. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE INVENTION The present invention aims to provide a film application assisting device, a film application machine and a film application module to solve the above-mentioned problems of the background art. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the technical solution adopted in this invention is to provide a film application auxiliary device including a positioning base having a storage groove for placing a protective film and an opening groove on one side communicating with the storage groove, wherein the bottom wall of the storage groove is provided with a plurality of spacers, all of which protrude from the bottom wall of the storage groove, and wherein the protruding height of the spacers farther from the opening groove is greater than the protruding height of the spacers closer to the opening groove, so that the protective film is in an inclined state after being placed in the storage groove.

[0007] Furthermore, a mold cavity groove for accommodating an electronic device is provided at the top of the accommodating groove, and a plurality of position limiting protrusions for supporting the electronic device are provided at the bottom of the mold cavity groove, and the protruding height of the position limiting protrusions farther from the opening groove is smaller than the protruding height of the position limiting protrusions closer to the opening groove so that the electronic device is in an inclined state after being placed in the mold cavity groove, and the side walls of the position limiting protrusions are the side walls of the accommodating groove.

[0008] Furthermore, a support base is formed at the bottom of the opening groove, protruding from the bottom wall of the receiving groove, and the support base and the position limiting protrusion cooperate to form a space for placing a protective film.

[0009] Furthermore, the positioning base is provided with exhaust grooves that connect the mold cavity groove and the accommodation groove, and the position limiting protrusions and the exhaust grooves are provided alternately.

[0010] Furthermore, the spacers include a first spacer and a second spacer, and both the first spacer and the second spacer are provided in strip shapes and are provided in parallel.

[0011] Furthermore, the bottom wall of the receiving groove is provided in a flat shape, the protruding height of the first spacer is 1 mm to 2 mm, and the protruding height of the second spacer is 0.5 mm to 1.3 mm.

[0012] Furthermore, the positioning base includes opposing first and second ends, the opening groove is provided at the first end, and the second end of the positioning base has a retreat groove for placing the edge of the protective film.

[0013] Furthermore, the present invention also provides a film applicator, which includes a packaging box and the film applicator auxiliary device, and the positioning base is placed in the packaging box.

[0014] Furthermore, the packaging box includes a main body and a cover plate, the positioning base is fixed to the main body, the cover plate can cover the mold cavity groove, and a set of position limiting beads is provided on the surface of the cover plate facing the mold cavity groove.

[0015] The present invention further provides a film application module, which includes a protective film and a film application device, wherein the protective film includes an adhesive film having a protective surface and an adhesive surface, and a release film adhered to the adhesive surface, wherein one end of the release film protrudes from the adhesive surface to form a tab, and the other end protrudes from the adhesive surface to form a pull tab, and when the protective film is placed in the receiving groove, the adhesive film faces downward and the release film faces upward, the tab is located in the withdrawal groove, the pull tab protrudes from the opening groove, and a pull label is provided on the release film. [Effects of the Invention]

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. By arranging the spacers at different heights, the protective film is tilted relative to the electronic device after placement, with one side higher and the other lower, creating a triangular exhaust space and a space for removing the release film between the protective film and the electronic device screen. The higher side of the protective film first contacts the electronic device screen, generating static electricity during the process of peeling off the release film. The lower side gradually exhausts due to the static electricity while adhering to the screen. Because the exhaust is unidirectional, there is no risk of trapped air bubbles, and air bubbles can be fully removed, resulting in good adhesion. Furthermore, even if the bottom of the receiving groove is deformed and raised due to the effect of the spacers increasing the height, it does not affect the flatness of the film application.

[0018] 2. The positioning base is provided with an exhaust groove connecting the mold cavity groove and the receiving groove. When a protective film is placed in the receiving groove, or when an electronic device is placed in the mold cavity groove, the exhaust groove allows external gas to more easily enter the cavity, maintaining the pressure balance between the inside and outside of the cavity and avoiding the suction effect caused by negative pressure, which is more advantageous for film application.

[0019] 3. A pair of position limiting beads is provided on the surface of the cover plate facing the molded groove, which serves to limit the position of the electronic device when wiping the screen of the electronic device, and also seals the opening groove with the position limiting beads when the cover plate is closed, preventing the film-attached part placed in the receiving groove from slipping out of the opening groove.

Furthermore, the terms "first," "second," and "third" are used merely for description and cannot be understood as indicating or suggesting relative importance.

[0023] In the description of the present invention, unless otherwise clearly defined or limited, terms such as "attached," "coupled," and "connected" should be understood in a broad sense, and may refer to, for example, a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, or internal communication between two elements. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0024] Furthermore, the technical features of the different embodiments of the present invention described below can be combined with each other unless they are inconsistent with each other. Example 1

[0025] As shown in FIG. 1, the film application auxiliary device provided in an embodiment of the present invention includes a positioning base 10 having a receiving groove 11 for placing a protective film 30 and an opening groove 12 communicating with the receiving groove 11 on one side thereof, and a plurality of spacers are provided on the bottom wall of the receiving groove 11, and the plurality of spacers all protrude from the bottom wall of the receiving groove 11, where the protruding height of the spacers farther from the opening groove 12 is greater than the protruding height of the spacers closer to the opening groove 12 so that the protective film 30 is in an inclined state after being placed in the receiving groove 11.

[0026] By providing spacers at different heights, the protective film 30 is tilted relative to the electronic device 40 after placement. By elevating the protective film 30 so that one side is higher and the other is lower, a triangular exhaust space and a space for removing the release film are formed between the protective film 30 and the screen of the electronic device. The higher side of the protective film 30 first contacts the screen of the electronic device 40, generating static electricity during the process of peeling off the release film. The lower side gradually exhausts due to the static electricity while adhering to the screen. Because the exhaust is unidirectional, there is no risk of trapped air bubbles, and air bubbles can be sufficiently removed, resulting in good adhesion. Furthermore, even if the bottom of the receiving groove 11 is deformed and raised due to the effect of the spacers increasing the height, this does not affect the flatness of the film application.

[0027] Specifically, the spacers include a first spacer 13 and a second spacer 14, both of which are strip-shaped and parallel to each other. The bottom wall of the receiving groove 11 is flat, and the protruding height of the first spacer 13 is 1 mm to 2 mm, preferably 1.5 mm. The protruding height of the second spacer 14 is 0.5 mm to 1.3 mm, preferably 1.0 mm. A mold cavity groove 15 for receiving the electronic device 40 is provided at the top of the receiving groove 11, and a plurality of position limiting protrusions 16 for supporting the electronic device 40 are provided at the bottom of the mold cavity groove 15. The protruding height of the position limiting protrusions 16 farther from the opening groove 12 is lower than the protruding height of the position limiting protrusions 16 closer to the opening groove 12 so that the electronic device is tilted after being placed in the mold cavity groove 15. The sidewalls of the position limiting protrusions 16 form the sidewalls of the receiving groove 11. In this case, the tilted protective film 30 can form a triangle with the tilted display screen of the electronic device 40, and as shown in Figure 5, the protective film 30 farthest from the opening groove 12 preferentially comes into contact with and adheres to the display screen of the electronic device 40. When the release film is pulled, air bubbles are sufficiently removed, and the protective film 30 gradually adheres to the display screen of the electronic device 40 until it is completely adhered to and adheres to the display screen of the electronic device 40. As shown in Figure 5, a triangular exhaust space is formed between the tilted protective film 30 and the tilted display screen of the electronic device 40, which allows air bubbles to be sufficiently removed, and a triangular space is formed between the tilted protective film 30 and the tilted display screen of the electronic device 40, which provides a pulling space for the release film, avoiding the release film getting stuck when pulled and improving the efficiency of film application.

[0028] In this embodiment, a support base 121 protruding from the bottom wall of the accommodating groove 11 is formed at the bottom of the opening groove 12. The support base 121 cooperates with the position limiting protrusions 16 to form a placement space for the protective film 30. There is a difference in height between the support base 121 and the bottom wall of the accommodating groove 11. Therefore, when the protective film 30 is placed in the accommodating groove 11 and the release film is peeled off to attach the film to the electronic device 40, the support base 121 acts as a blocking and position limiting element, preventing the protective film 30 from being pulled out along the opening groove 12. This ensures that the film attachment process is carried out normally. Conventional film attachment devices require position limiting pins and corresponding position limiting holes in the film attachment device to limit the position of the protective film during attachment. However, the film attachment auxiliary device provided in this embodiment does not require position limiting pins and position limiting holes, resulting in a simple structure and cost savings.

[0029] In another embodiment, the tops of the multiple position limiting protrusions 16 are located on the same plane, and after the electronic device 40 is placed in the mold cavity groove 15, the electronic device 40 can be positioned horizontally due to the supporting action of the position limiting protrusions 16. In this case, the inclined protective film 30 can form a triangular exhaust space and a space for removing the mold release film between the display screen of the electronic device 40 and the protective film 30.

[0030] In this embodiment, a third spacer 111 is further provided at the middle position of the bottom wall of the accommodating groove 11. The protruding height of the third spacer 111 is smaller than that of the first spacer 13 and the second spacer 14, and the protruding height of the third spacer 111 is preferably 0.5 mm. When the protective film 30 is placed in the accommodating groove 11, the middle position of the bottom of the protective film 30 is raised. In this state, external air can more easily enter the bottom of the protective film 30, making it easier to maintain the balance of internal and external pressure, avoiding the suction action caused by negative pressure and affecting the film attachment effect, and making it easier to remove the protective film 30 from the accommodating groove 11.

[0031] Furthermore, the positioning base 10 is provided with exhaust grooves 17 that connect the mold cavity groove 15 and the receiving groove 11, and the position limiting protrusions 16 and the exhaust grooves 17 are arranged alternately. The provided exhaust grooves 17 allow external gases to more easily enter the cavity, which is more advantageous for film application. In this embodiment, the exhaust grooves 17 are provided on the side walls of the mold cavity groove 15 and the receiving groove 11. To ensure uniform exhaust, there are multiple exhaust grooves 17, and they are arranged around the mold cavity groove 15 in order to ensure uniform exhaust. The position limiting blocks and exhaust grooves 17 are arranged alternately, which makes the structural layout more rational.

[0032] In other embodiments, the exhaust groove 17 may be an independent hole-like structure, and the exhaust groove 17 may be opened directly on the positioning base 10, and the exhaust groove 17 may communicate with the mold cavity groove 15 and the storage groove 11 so as to be able to exhaust air.

[0033] Furthermore, the positioning base 10 includes opposing first and second ends 101 and 102, and the opening groove 12 is provided at the first end 101, and the second end 102 of the positioning base 10 has a recess groove 18 for placing the ear 31 of the protective film 30.

[0034] Specifically, the protective film 30 is a tempered glass film, and includes an adhesive film including a protective surface and an adhesive surface, and a release film adhered to the adhesive surface. One end of the release film protrudes from the adhesive surface to form a tab 31, and the other end protrudes from the adhesive surface to form a pull tab 32. When the protective film 30 is placed in the receiving groove 11, the adhesive film faces downward and the release film faces upward, with the tab 31 located in the retraction groove 18 and the pull tab 32 protruding from the opening groove 12. A pull label is provided on the release film to inform the user that a pull operation can be performed. In a later step, the electronic device 40 is placed in the receiving groove 15 with the screen facing the protective film 30. After placing the electronic device 40, the protective film 30 forms a triangular space with the electronic device 40, with the higher side first contacting the screen of the electronic device 40 and the lower side gradually venting under the weight of the electronic device 40 as it adheres to the screen. When the adhesive film first contacts one end of the screen, gas is gradually vented from one end to the other, achieving uniform venting and solving the problem of air bubbles forming when the tempered glass film is adhered. Because the venting is one-way, there is no risk of air bubbles being trapped.

[0035] Furthermore, a buffer airbag is provided within the receiving groove 11 to protect the protective film 30. Since the protective film 30 is a tempered glass film, it needs to be protected to prevent rupture and damage. By providing the annular raised buffer airbag directly on the bottom wall of the receiving groove 11, the protective film 30 is kept safer within the receiving groove 11 and is less susceptible to damage from external impacts.

[0036] Furthermore, the positioning base 10 is provided with a finger groove 19 communicating with the mold cavity groove 15, and the finger groove 19 is provided at the position of the second end 102 of the positioning base 10. A finger can be inserted into the finger groove 19 to directly contact the electronic device 40, and the electronic device 40 can be removed after the film attachment is completed.

[0037] The opening groove 12 includes two position limiting side walls 122, and the distance between the two position limiting side walls 122 is smaller than the width of the mold hole groove 15, which serves to limit and fix the position of the attached electronic device 40, and prevents the electronic device 40 from slipping out of the opening groove 12 during the film attachment operation and affecting the film attachment effect. Example 2

[0038] As shown in FIG. 2, the film applicator provided in this embodiment of the present invention includes a packaging box 20 and the film applicator auxiliary device described in embodiment 1, and the positioning base 10 is placed in the packaging box 20. The positioning base 10 may be fixed in the packaging box 20 in the form of attachment or adhesive.

[0039] Specifically, the packaging box 20 includes a main body 21 and a cover plate 22. The positioning base 10 is fixed to the main body 21, and may be fixed by adhesive. During the film attachment operation, the cover plate 22 can cover the mold groove 15, and the cover plate 22 limits the position of the electronic device 40, making the film attachment easier.

[0040] A set of position limiting beads 23 is provided on the surface of the cover plate 22 facing the mold groove 15. This serves to limit the position of the electronic device 40 when wiping the screen of the electronic device 40, and when the cover plate 22 is closed, the position limiting beads 23 seal the opening groove 12 to prevent the film-attached component placed in the accommodation groove 11 from slipping out of the opening groove 12. Example 3

[0041] As shown in FIG. 4, the film application module provided in this embodiment of the present invention includes a protective film 30 and the film application device described in Example 2. The protective film 30 is a tempered glass film. The protective film 30 includes an adhesive film having a protective surface and an adhesive surface, and a release film attached to the adhesive surface. One end of the release film protrudes from the adhesive surface to form a tab 31, and the other end protrudes from the adhesive surface to form a pull tab 32. When the protective film 30 is placed in the receiving groove 11, the adhesive film faces downward and the release film faces upward, the tab 31 is located in the retraction groove 18, the pull tab 32 protrudes from the opening groove 12, and a pull label is provided on the release film to indicate to the user that it can be pulled.

[0042] In this embodiment, the protective film 30 and the film applicator are sold as a set, and the protective film 30 is placed in the receiving groove 11 and the positioning base 10 is directly packaged in the packaging box 20. In this case, the film applicator assisting device serves as a protective cover to protect the protective film 30, eliminating the need to attach a separate protective cover to the protective film 30. When a film needs to be applied to the electronic device 40, the protective film 30 is first placed in the receiving groove 11 with the adhesive film facing downward and the release film facing upward, the tab 31 positioned in the retraction groove 18, and the pull tab 32 protruding from the opening groove 12. Then, the electronic device 40 is placed in the mold cavity groove 15, and the screen side of the electronic device 40 is pressed against the protective film 30. After the electronic device 40 is placed, the protective film 30 forms a triangular space with the electronic device 40. When the pull tab 32 is pulled, the release film separates from the adhesive film and is pulled out from the opening groove 12, exposing the adhesive surface of the adhesive film. The higher side first comes into contact with and adheres to the screen of the electronic device 40, while the lower side gradually exhausts air under the weight of the electronic device 40 as it adheres. This achieves uniform exhaust, solves the problem of air bubbles occurring when the tempered glass film is adhered, and enables automatic application of the protective film 30.

[0043] Compared to existing technology, the protruding height of the first spacer 13 is higher than that of the second spacer 14, so that the protective film 30 is tilted relative to the electronic device 40 after placement, elevating the protective film 30 so that one side is higher and the other is lower. The higher side of the protective film 30 first contacts the screen of the electronic device 40, generating static electricity during the process of peeling off the release film. The lower side gradually releases static electricity while adhering to the screen. Because the exhaust is one-way, there is no risk of air bubbles being trapped, and air bubbles can be sufficiently removed, resulting in good adhesion. Furthermore, due to the height-increasing effect of the first spacer 13 and second spacer 14, even if the bottom of the receiving groove 11 is deformed and raised, it does not affect the flatness of the film application.

[0044] The examples of the specific embodiments are all preferred embodiments of the present invention and do not limit the scope of protection of the present invention, and therefore any equivalent modifications made according to the structure, shape and principle of the present invention should be included within the scope of protection of the present invention.
