In order to solve this technical problem, the existing technology will The structure for positioning the mobile phone is set as a frame structure that can be assembled and disassembled and set on the film applicator. In this way, different frame structures only need to be injection-molded for electronic products of different sizes and models, thereby reducing the injection molding cost of the mold to a certain extent; and the protective film is positioned on the film applicator by adopting the upper protection sheet method, that is, upper protection sheets of different sizes are cut out through a universal positioning structure to meet the requirement that protective films of different sizes can be adapted and positioned on one film applicator; in addition, for the positioning of electronic products, the prior art also proposes to open a positioning groove of a relatively large size on the film applicator, and then adopt a positioning structure of supplementary foam cotton around the positioning groove, and by adding foam cotton materials of different sizes, it can meet the adaptation of electronic products of different models;

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-6 In the embodiment of the present utility model, please refer to Figures 1-2 In the embodiment of the utility model, a universal film applicator is proposed which is realized by post-CNC processing and is used to assist the protective film 2 in being attached to the screen 1 to be attached with the film. The film applicator includes a main body 10 and an upper protective sheet 20 positioned on the main body 10 of the film applicator. The main body 10 of the film applicator is used to position the screen 1 to be attached with the film, and the upper protective sheet 20 is used to attach the protective film 2. When the main body 10 of the film applicator and the upper protective sheet 20 are positioned and matched, the screen to be positioned and the protective film 2 will be able to be accurately positioned, so that the protective film 2 can be accurately attached to the screen 1 to be attached with the film. In terms of the size and model selection of the protective film 2 and the screen 1 to be attached with the film, protective films 2 of different sizes can be attached to the specified position on the upper protective sheet 20 to achieve accurate positioning with the screen 1 to be attached with the film applicator main body 10. In order to enable the protective film 2 to be The fit between the film 2 and the upper protective sheet 20 can be more precise, and the sizes of the upper protective sheet 20 and the protective film 2 can be matched. In view of the positioning of the screen 1 to be filmed of different sizes and models and the film applicator body 10, that is, in order to enable the film applicator body 10 to flexibly adapt to the screen 1 to be filmed of different sizes and models, thereby reducing the manufacturing cost of the mold in the production process, the utility model arranges the film applicator body 10 to have a positioning groove 11, and a supporting structure 12 is formed in the positioning groove 11, and a CNC-processed groove 13 for positioning and placing the screen 1 to be filmed is provided on the supporting structure 12. The upper protective sheet 20 is used to position the protective film 2 on the film applicator body 10, so that the protective film 2 can be positioned and matched with the screen 1 to be filmed positioned on the CNC-processed groove 13.

[0028] That is, in the setting of the mold, a support structure 12 can be formed, and this support structure 12 can position the current smallest size of the screen 1 to be filmed, or based on the current smallest size of the screen 1 to be filmed, it is set to position a simulated smallest size of the screen 1 to be filmed; then after the film applicator is produced by injection molding, according to the market demand for the film applicator corresponding to the electronic products of different sizes of the screen 1 to be filmed, the support structure 12 is further processed by the later CNC processing;

[0029] Therefore, by processing the CNC processing support structure 12 to process different sizes of CNC processing grooves 13 based on the same size type of film applicator, the film applicator can flexibly adapt to the positioning of electronic products of different sizes and models before CNC processing; therefore, only one size of mold needs to be manufactured in the production of this type of film applicator, which can greatly reduce the manufacturing cost of the mold; and because the film applicator can adapt to the positioning of electronic products of different sizes before CNC processing, the manufacturer's inventory can be reduced, and some film applicators that have been CNC processed and then meet the positioning of electronic products with smaller sizes can be CNC processed again to meet the positioning of electronic products with larger sizes, which greatly improves the flexibility of the film applicator in positioning electronic products; thereby effectively reducing inventory.

[0030] See also Figure 3 In the embodiment of the utility model, it is proposed that one side of the CNC processing groove 13 overlaps with one side of the positioning groove 11. This technical solution is proposed based on the fact that the electronic products that need to be self-filmed by users are generally of a four-sided structure. Taking mobile phones as an example, the CNC processing groove 13 and the positioning groove 11 have a structure in which one side overlaps, so that only the dimensions of the other three sides need to be processed during the CNC processing process, thereby reducing the CNC processing time to a certain extent. In addition, through the structural setting of overlapping one side, when modifying the processing size of the CNC processing groove 13 for electronic products of different sizes and models, this overlapping side can be used as a reference, and the positional relationship between the upper protective sheet 20 and the protective film 2 corresponding to the CNC processing groove 13 can also be referenced by this overlapping side.

The square frame structure is formed with multiple through this setting, which plays a role in bearing the electronic products. After CNC processing, some horizontal support edges 14 or vertical support edges 15 form a right-angle structure as shown in the figure, thereby supporting the side of the electronic product to achieve the purpose of positioning the electronic product; further, two vertical support edges 15 are provided, and the two vertical support edges 15 are parallel to each other. The positioning slot 11 is divided into three areas: left, middle and right, to ensure that the electronic product can be firmly placed on the support structure 12. The transverse support edges 14 are arranged in the left and right areas where the positioning slot 11 is divided by the longitudinal support edges 15, and their edges are further positioned. At the same time, after CNC processing, the transverse support edges 14 are formed with a right-angle structure to abut against the electronic product; three groups of transverse support edges 14 are arranged in each area, and the three groups of transverse support edges 14 are respectively arranged at the front, middle and rear positions of the area, which can ensure that the electronic product will not tilt or shift, and each group of transverse support edges 14 is provided with two, taking into account that some electronic products may be provided with buttons on the side, each group of transverse support edges 14 is provided with two, so that the electronic product can be positioned without shifting after a reasonable position is reserved to accommodate the buttons.

[0032] See also Figure 1-3 In the embodiment of the utility model, a hand buckle portion 16 is further provided at one end of the positioning groove 11 to facilitate taking electronic products. Based on the positioning of the upper protection sheet 20, a traditional positioning method is adopted, that is, an upper protection positioning structure 17 is provided on the film applicator body 10, and the upper protection sheet 20 is positioned on the film applicator body 10 through the upper protection positioning structure 17. Figure 1 and Figure 2 As shown, a film applicator with only a base or a film applicator with a base 101 and an upper cover 102 is provided. For the film applicator with only a base, when positioning the upper protective sheet 20, a certain lifting structure is required to make the protective film 2 and the screen 1 to be pasted in a state of clearance fit after positioning, so that the operator can controllably guide the protective film 2 to be attached to the screen 1 to be pasted; while using a film applicator with a base and an upper cover, the upper protective sheet 20 can be directly fixed on the upper cover, and when the base and the upper cover are positioned and closed, the protective film 2 and the screen 1 to be pasted will be automatically and accurately positioned, and the height of the upper cover itself can be set so that the protective film 2 after covering is clearance fit with the screen 1 to be pasted. In addition, in order to adapt to some lenses with protruding structures on the back of mobile phones, an opening 18 of a certain adaptive size and shape needs to be provided in the positioning groove 11.
