[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] A positioning fixture for applying protective film to glass, as shown in the reference. Figure 1-5 The device includes a positioning fixture 100, which comprises an upper cover 110 and a lower positioning chamber 120. The lower positioning chamber 120 has a receiving cavity 123 with a top opening for accommodating a protective film 200 and a smart device (in this case, a mobile phone) 300 stacked sequentially from bottom to top. The upper cover 110 is fastened to the lower positioning chamber 120 and covers the receiving cavity 123. Through the fastening structure of the upper cover 110 and the lower positioning chamber 120, the protective film 200 and the smart device 300 placed in the receiving cavity 123 can be covered, which can effectively prevent dust from entering during film application, improve the cleanliness and success rate of film application, and through the cooperation of the receiving cavity 123 and the upper cover 110, it can also help limit the placement position of the protective film 200 and the smart device 300, enabling the alignment operation of the two and further improving the film application effect.

[0036] The shape and size of the receiving cavity 123 can be prefabricated according to the shape and size of different smart devices 300, and are not limited here. The receiving cavity 123 can also be designed with clearance holes corresponding to the buttons in the smart device 300.

[0037] Further, please refer to Figure 1 , Figure 3 as well as Figure 4 As shown, the upper cover 110 is provided with several pressing members 112. When the upper cover 110 is fastened to the lower positioning chamber 120, the bottom of the pressing members 112 presses against the back of the smart device 300 to limit the vertical position of the smart device 300. The pressing members 112 are staggered from the lens of the smart device 300. The several pressing members 112 are distributed at intervals along the length of the smart device 300. The design of the pressing members 112 can avoid contact with the camera and prevent lens wear. On the other hand, the distribution of the pressing members 112 at intervals along the length of the device can ensure that the pressure is evenly applied to the back of the device, ensure consistent force on the film, reduce bubbles and offset, and thus improve the quality of film application.

[0038] It is worth mentioning that the bottom of the pressure member 112 is set with an arc-shaped structure. The design of the bottom shape of the pressure member 112 reduces the risk of scratching the back of the smart device 300.

[0039] In this example, there are two pressing members 112. Of course, in other embodiments, there may be three or more pressing members 112, which is not limited here.

[0040] The specific principle is as follows: the glass surface of the protective film 200 is placed in the receiving cavity 123 with the screen surface of the smart device 300 facing each other. Then, the top cover 110 is fastened in the receiving cavity 123. After fastening, the pressing member 112 can press against the back of the smart device 300, so that the automatic film application operation can be performed. After the film is applied, the top cover 110 is moved upward and the smart device 300 can be removed. The release film is then peeled off, and the film application operation is completed.

[0041] In this embodiment, please refer to Figure 1 as well as Figure 4 As shown, the receiving cavity 123 has openings at both its front and rear ends, and several positioning posts 122 are provided on the openings. The release film in the protective film 200 has positioning holes 210 at both ends that are adapted to be inserted into the positioning posts 122. The insertion and cooperation of the positioning posts 122 and the positioning holes 210 can realize the rapid and accurate positioning of the protective film 200, simplify the operation steps, and prevent the protective film 200 from sliding or tilting during the application process. The design of the openings on both sides of the receiving cavity 123 also facilitates the loading and unloading operation of the smart device 300. Preferably, there are two positioning posts 122 at each end of the opening, which are symmetrically arranged around the central axis of the opening, which can further improve the positioning effect of the protective film 200.

[0042] In this embodiment, please refer to Figure 1 as well as Figure 4 As shown, several protrusions 124 are spaced apart on the bottom edge of the receiving cavity 123. The protrusions 124 abut against the front edge of the smart device 300, and their inner surfaces are flush with the outer edge of the display screen in the smart device 300. A sponge strip 140 is also provided at the center of the bottom of the receiving cavity 123, which is in contact with the bottom surface of the protective film 200. The design of the protrusions 124 can further restrict the relative position of the smart device 300 and the protective film 200 in the receiving cavity, and can further improve the positioning accuracy. The sponge strip 140 itself can support the protective film 200, which can ensure that the protective film 200 and the smart device 300 are fully and effectively adhered. In addition, the sponge strip 140 has a certain degree of elasticity, which can effectively prevent the protective film 200 from being broken by impact during transportation.

[0043] It is worth noting that the advantage of the sponge strip 140 being located in the middle of the receiving cavity 123 is that when applying the film, the protective film 200 and the smart device 300 will first be bonded together under force, and then gradually the air will be released outwards. No air bubbles will be formed during the application process, which can further improve the subsequent film application quality.

[0044] In this embodiment, please refer to Figure 1 as well as Figure 4As shown, a folding part 130 connects the upper cover 110 and the lower positioning compartment 120. The upper cover 110 can be flipped and fastened onto the lower positioning compartment 120 along the folding part 130. The folding part 130 connects the upper cover 110 and the lower positioning compartment 120, making the fixture easy to open and close, preventing the upper cover 110 from being lost, and improving portability and storage efficiency. The folding part 130 has creases for folding.

[0045] In other embodiments, the upper cover 110 and the lower positioning compartment 120 can also be designed as separate parts, which can realize the replacement of individual parts of the upper cover 110 and the lower positioning compartment 120, so as to save the overall maintenance cost.

[0046] In this embodiment, please refer to Figure 1 as well as Figure 4 As shown, the inner wall of the upper cover 110 is provided with a plurality of latching protrusions 111 spaced circumferentially, and the lower positioning chamber 120 is provided with latching grooves 121 corresponding to the latching protrusions 111. When the upper cover 110 is flipped and fastened onto the lower positioning chamber 120, the latching protrusions 111 and the latching grooves 121 engage. The engaging structure of the latching protrusions 111 and the latching grooves 121 ensures that the upper cover 110 is tightly fixed after being fastened, preventing accidental opening and ensuring the stability and safety of the film application process. The latching protrusions 111 can be made of a material with a certain degree of elasticity, such as plastic, and can be removed from the latching grooves 121 with slight force to complete the separation operation. Of course, the latching protrusions 111 can also be designed on the lower positioning chamber 120, and the latching grooves 121 can be designed inside the upper cover 110; this is not limited here.

[0047] In this embodiment, please refer to Figure 1 as well as Figure 2 As shown, the top front end of the upper cover 110 is recessed downward to form a concave surface 113. When the upper cover 110 is flipped and fastened onto the lower positioning chamber 120, the concave surface 113 and the lower positioning chamber 120 enclose an opening and closing handle space. The handle space formed by the concave surface 113 and the lower positioning chamber 120 makes it easy for the user to apply force to open the upper cover 110. The design is user-friendly and improves the operating experience.

[0048] In this embodiment, please refer to Figure 5 As shown, the top of the cover 110 is also recessed downward to form a receiving groove 114 for accommodating the lens protective film 400. The receiving groove 114 for storing the lens protective film 400 is designed on the cover 110. The integrated design of the receiving groove 114 allows the lens protective film 400 to be placed together with the positioning fixture 100 in the outer packaging (not shown in the figure), which facilitates the storage and use of the lens protective film 400, making the product have a two-in-one effect and greatly reducing the packaging cost of the two protective films.

[0049] Of course, in other application scenarios where the lens protective film 400 is not required, the receiving slot 114 may not be necessary.

[0050] In this embodiment, please refer to Figure 4 As shown, the lower positioning compartment 120 is also equipped with a hanging ear 125 with a hanging hole. The design of the hanging ear 125 facilitates the hanging and storage of the positioning fixture 100, saves space, and simplifies product packaging. Of course, in other application scenarios, the hanging ear 125 may not be necessary.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
