In one embodiment, referring to fig. 10, 11 and 12, the edge of the side of the rubber mold 13 close to the outer mold plate 11 is provided with a rounded corner 133, and the radius of the rounded corner 133 is larger than the bending radius of the side of the inner curved surface 911. The radius of fillet 133 on the rubber mold 13 is set to be larger, so that the rubber mold 13 can be conveniently deformed by hot pressing the membrane 92, and when the rubber mold 13 extends into the inner curved surface 911 of the casing 91, the guiding effect can be achieved, and the membrane 92 is prevented from being scratched when the edge of the rubber mold 13 is wiped to the side edge of the casing 91.

In one embodiment, referring to fig. 13, an end surface of the rubber mold 13 close to one side of the outer mold plate 11 is an arc surface 134 with a convex middle portion, so that when the rubber mold 13 extends into the inner curved surface 911 of the casing 91, the middle portion of the rubber mold 13 first pushes the membrane 92 to contact with the middle portion of the inner curved surface 911 of the casing 91, and the rubber mold 13 continues to be pushed to move toward the outer mold plate 11, and then under the action of pressure, the rubber mold 13 gradually deforms, so that the rubber mold 13 gradually deforms from the middle portion to the edge, and in this process, the membrane 92 gradually deforms from the middle portion to the edge and is attached to the inner curved surface 911 of the casing 91, so that the gas between the casing 91 and the membrane 92 can be better squeezed out, the gas between the casing 91 and the membrane 92 can be better discharged, and bubbles.

In one embodiment, the protruding height of the arc-shaped surface 134 of the mold 13 near the outer mold plate 11 is in the range of 0.5-5mm, so that the mold 13 can well discharge the air between the casing 91 and the membrane 92, and at the same time, the mold 13 can be well deformed slightly, and better fit the shape of the inner curved surface 911 of the casing 91.

In one embodiment, referring to fig. 14, the mold 13 includes a heat conducting block 131 and an adhesive layer 132 disposed on the heat conducting block 131 to facilitate heating the membrane 92 and to facilitate micro-deformation of the mold 13 to fit the inner curved surface 911 of the housing 91.

In an embodiment, referring to fig. 16, the inner curved surface film pasting device 100 further includes a heating element 113, the heating element 113 is installed on the outer mold plate 11 to heat the outer mold plate 11, and further can heat the case 91 in the accommodating groove 111 of the outer mold plate 11, so that when the film 92 contacts the case 91 during film pasting, the temperature difference between the film 92 and the case 91 is reduced, thereby preventing the heat loss caused by the excessive temperature difference from affecting the film pasting effect, and reducing the stress generated by the excessive temperature difference during film pasting, and improving the film pasting effect.

In one embodiment, referring to fig. 16, the heating members 113 may be plate-shaped heating members to be conveniently mounted on the outer mold plate 11 to heat the outer mold plate 11. In one embodiment, the heating member 113 may be a heating wire, a heating rod, or the like directly disposed in the outer mold plate 11.

In one embodiment, referring to fig. 17, the inner curved surface film laminating apparatus 100 further includes a vacuum box 19, and the outer mold plate 11 and the support plate 12 are disposed in the vacuum box 19, so that during film laminating, air between the inner curved surface 911 of the housing 91 and the film 92 can be pumped out through the vacuum box 19, and bubbles can be prevented from occurring between the film 92 and the housing 91 during film laminating.

In one embodiment, the outer mold plate 11, the glue mold 13, the support plate 12, and the heater 14 may be integrally disposed in a vacuum box 19. If the vacuum box 19 is provided with a window 190 for the integral entering and exiting of the outer form 11, the rubber form 13, the support plate 12 and the heater 14.

In one embodiment, the vacuum box 19 includes an upper case 192 and a lower case 191 that are engaged with each other, the upper case 192 and the lower case 191 are engaged to form a sealed chamber, the lower case 191 is provided with a port 193 for connecting to an air extractor for air extraction, and a driving mechanism is provided in the lower case 191 for driving the rubber mold 13 to move. Therefore, a negative pressure environment can be realized, so that the gas between the inner curved surface 911 of the casing 91 and the diaphragm 92 can be pumped out, and bubbles can be prevented from being generated between the diaphragm 92 and the casing 91 during film pasting. Of course, in some embodiments, a driving mechanism may be disposed in the upper case 192 to drive the outer mold plate 11 to move. In some embodiments, a port 193 may also be provided on the upper housing 192 to allow connection to an air extractor for air extraction.

In one embodiment, an air passage (not shown) communicating with the accommodating groove 111 may be disposed on the support plate 12 or the outer mold plate 11, so that when the support plate 12 and the outer mold plate 11 cooperate to clamp the membrane 92, air in the accommodating groove 111 may be exhausted through the air passage, thereby preventing air bubbles from occurring between the membrane 92 and the housing 91 during film pasting.

The inner curved surface film pasting device 100 of the embodiment of the application clamps the edge of the membrane 92 by the support plate 12 and the outer template 11 in a matching manner, so as to fix the edge of the membrane 92. The rubber mold 13 penetrates through the support plate 12 and abuts against the membrane 92 to gradually perform hot-pressing deformation on the membrane 92, so that the membrane 92 gradually deforms to approach the inner curved surface 911 of the shell 91, and then the rubber mold 13 abuts against the inner curved surface 911 of the shell 91 to slightly deform the rubber mold 13 and the membrane 92 so as to be matched and attached to the inner curved surface 911 of the shell 91. A large deformation of the membrane 92 can be achieved in order to achieve a membrane attachment to the deep-curved inner surface. The inner curved surface film pasting device 100 of the embodiment of the application can be used for pasting the inner curved surface 911 with the bending height of the side edge 912 being 0-15 mm. The side 912 of the inner curved surface 911 has a curvature height of 0, which means that the side 912 of the inner curved surface 911 is not curved and the inner curved surface 911 is a plane. The side 912 of the inner curved surface 911 is curved 15mm high, which means that the height from the edge of the side 912 of the inner curved surface 911 to the bottom of the inner curved surface 911 is 15mm, i.e., the depth of the inner curved surface 911 is 15 mm.

The inner curved surface film pasting device 100 of the embodiment of the application can not only paste the film to the deep-bending inner curved surface, but also paste the film to the flat plate, for example, directly support the film 92 through the rubber mold 13, so as to paste on the flat plate. The inner curved surface film pasting device 100 of the embodiment of the application can paste the film on the inner curved surface 911 with the bending angle of the side 912 being 0-95 degrees. The side 912 of the inner curved surface 911 is bent by 0 degree, which means that the inner curved surface 911 is a plane; while the side 912 of the inner curved surface 911 is curved 90 degrees, meaning that the side 912 of the inner curved surface 911 is perpendicular to the bottom of the inner curved surface 911. Because the rubber mold 13 can finally drive the membrane 92 to deform slightly, when the bending angle of the side 912 of the inner curved surface 911 is slightly larger than 90 degrees, the membrane 92 can also be adapted to deform and be attached to the inner curved surface 911.

The inner curved surface film pasting device 100 of the embodiment of the application can finally drive the film 92 to deform slightly due to the rubber mold 13, can paste the inner curved surface 911 with the bending radius of the side 912 being more than 0.5mm, and is wider in application range.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
