[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0036] Please see Figures 1 to 4 This embodiment proposes a film-applying fixture for attaching a protective film to a product. The fixture includes a fixture body 1 and a positioning part 2. The fixture body 1 has a positioning groove 111 for accommodating and positioning the protective film. The positioning groove 111 contains evenly distributed first vacuum suction holes 112 and second vacuum suction holes 113 for adsorbing the protective film. The second vacuum suction holes 113 surround the edge of the protective film, and the distance between two adjacent second vacuum suction holes 113 is smaller than the distance between two adjacent first vacuum suction holes 112. The positioning part 2 is disposed on the fixture body 1 and is used to position the product so that the product is directly aligned with the protective film.
[0037] Understandably, before applying the protective film, the protective film is placed in the positioning groove 11, and a portion of the groove wall of the positioning groove 111 is made to fit against the edge of the protective film. This facilitates the positioning of the protective film in the positioning groove 111 for positioning. Under the action of the first vacuum suction hole 112 and the second vacuum suction hole 113, the protective film can be adsorbed and fixed to ensure its stability. The distance between two adjacent second vacuum suction holes 113 is smaller than the distance between two adjacent first vacuum suction holes 112 to increase the adsorption force on the edge of the protective film. This avoids problems such as edge curling or wrinkling when the release film is removed. As the product moves closer to the protective film, the positioning part 2 ensures the accuracy of the product and the protective film during the bonding process, thereby improving the bonding efficiency of the protective film.
[0038] It should be noted that multiple second vacuum suction holes 113 are arranged around the edge of the protective film, thereby forming an annular area within the positioning groove 111. Multiple first vacuum suction holes 112 are arranged in an array within this annular area to further ensure the stability of the film-applying fixture when adsorbing the protective film.
[0039] Furthermore, the depth of the positioning groove 111 is less than the thickness of the protective film. It is understood that after the protective film is placed in the positioning groove 111, the protective film can protrude from the positioning groove 111, so that the product and the protective film can be adhered, thereby further improving the adhesion accuracy of the protective film.
[0040] Some products have protruding pins on their surfaces, such as some 5G base station housings. Therefore, a first positioning hole needs to be provided on the protective film to accommodate the pin. However, when removing the release paper from the protective film, the first positioning hole can easily shift, thus affecting the quality of the protective film application.
[0041] Therefore, in this embodiment, a second positioning hole 115 is provided in the positioning groove 111, with the first positioning hole and the second positioning hole 115 facing each other. The film-applying fixture also includes a positioning pin, which can pass through the first positioning hole and be inserted into the second positioning hole 115, and the peripheral wall of the positioning pin is adapted to position the first positioning hole. It can be understood that after the protective film is placed in the positioning groove 111, the positioning pin is inserted through the first positioning hole and then into the second positioning hole 115. The positioning pin can position the first positioning hole, and then the release film is removed. This arrangement can prevent the first positioning hole from shifting during the removal of the release film, thereby further improving the bonding quality of the protective film.
[0042] It should be noted that the positioning pin can be a pin on the product. After the protective film is placed in the positioning groove 111, the first vacuum suction hole 112 and the second vacuum suction hole 113 can adsorb the protective film. Then, the pin is inserted through the first positioning hole and then into the second positioning hole 115. After removing the release film, the adhesive side of the protective film is aligned with the film to be applied to the product. The product and the protective film are brought close together to complete the application of the protective film.
[0043] The setting of the first positioning hole can increase the exposed edge of the protective film. However, the first vacuum suction hole 112, which is evenly distributed inside the positioning groove 111, cannot guarantee that the edge of the first positioning hole will be adsorbed, which can easily cause the edge of the first positioning hole to lift or wrinkle during the removal of the protective film.
[0044] Therefore, in this embodiment, a plurality of third vacuum suction holes 114 are provided in the positioning groove 111, and the third vacuum suction holes 114 are arranged around the edge of the first positioning hole. It can be understood that the third vacuum suction holes 114 are connected to the vacuum chamber. When the first vacuum suction holes 112 and the second vacuum suction holes 113 adsorb the protective film, the third vacuum suction holes 114 can adsorb the edge of the first positioning hole, thereby preventing the edge of the first positioning hole from lifting or wrinkling.
[0045] Furthermore, the distance between two adjacent third vacuum suction holes 114 is smaller than the distance between two adjacent first vacuum suction holes 112. This arrangement ensures that the adsorption force of the third vacuum suction hole 114 on the protective film is greater than that of the first vacuum suction hole 112 on the protective film, thereby further preventing the protective film from peeling or wrinkling at the edges.
[0046] Specifically, the diameters of the first vacuum suction hole 112, the second vacuum suction hole 113, and the third vacuum suction hole 114 are 0.5 mm to ensure the adsorption force of the first vacuum suction hole 112, the second vacuum suction hole 113, and the third vacuum suction hole 114 on the protective film.
[0047] In this embodiment, the positioning part 2 includes multiple positioning blocks 21, each positioning block 21 having a positioning surface 211 that fits against the side wall of the product. It is understood that when placing the product, the side wall of the product is fitted with the corresponding positioning surface 211 to complete the product positioning. This arrangement improves the film application efficiency of the product.
[0048] For example, among the multiple positioning blocks 21, some positioning blocks 21 are first positioning blocks and some positioning blocks 21 are second positioning blocks. The first positioning blocks are arranged along the length direction of the product to limit the width direction of the product, and the second positioning blocks are arranged along the width direction of the product to limit the length direction of the product.
[0049] Furthermore, the positioning surface 211 is flush with the wall of the positioning groove 111. It can be understood that since the positioning groove 111 can position the edge of the positioning groove 111, and the positioning surface 211 can position the side wall of the product, the positioning of the product and the protective film can be completed. This setting can further improve the film application efficiency of the product.
[0050] In this embodiment, multiple positioning grooves 111 are spaced apart, and the arrangement of the second vacuum suction holes 113 in the multiple positioning grooves 111 is different. This arrangement allows for the application of films to different models of products, thereby improving the applicability of the film-applying fixture.
[0051] Furthermore, among the multiple positioning grooves 111, some positioning grooves 111 are provided with a second positioning hole 115 and a third vacuum suction hole 114, while some positioning grooves 111 may not be provided with a second positioning hole 115 and a third vacuum suction hole 114. This arrangement can further improve the applicability of the film-applying fixture.
[0052] In this embodiment, the fixture body 1 includes a first fixture plate 11, a second fixture plate 12, and an air connector (not shown in the figure). A positioning groove 111 is disposed on the first fixture plate 11. The second fixture plate 12 has a vacuum groove 121, which is directly opposite to the side of the first fixture plate 11 that is away from the positioning groove 111. When the first fixture plate 11 is covered by the second fixture plate 12, the first fixture plate 11 and the vacuum groove 121 can form a vacuum cavity. The vacuum cavity is connected to the first vacuum suction hole 112 and the second vacuum suction hole 113. An air connector is disposed on the first fixture plate 11 or the second fixture plate 12, and one end of the air connector is connected to the vacuum cavity, while the other end is connected to an external vacuum pumping component through an air pipe. Understandably, after the protective film is placed in the positioning groove 111, the vacuuming component can extract gas from the vacuum chamber through the air pipe and air connector, thereby adsorbing and fixing the protective film in the positioning groove 111, thus ensuring that the protective film is flat, wrinkle-free, and bubble-free in the positioning groove 111.
[0053] Furthermore, a sealing groove 122 is provided on the second fixture plate 12, the sealing groove 122 surrounds the vacuum groove 121, and a sealing ring is provided inside the sealing groove 122. It can be understood that the sealing groove 122 is an annular groove, and the sealing ring is provided inside the sealing groove 122 to ensure the sealing effect of the vacuum chamber, thereby ensuring the flatness of the protective film.
[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
