Description

Technical Field

[0001] The present invention relates to the technical field of film coating structures, specifically a curved surface film coating mechanism for concave-convex three-dimensional mobile phone cases. Background Technique

[0002] Mobile phone cases can prevent the mobile phone from being directly damaged when dropped or impacted by external forces. Especially when the mobile phone falls, the mobile phone case can play a buffering role and reduce the impact force on the mobile phone. However, during long-term use of the mobile phone case, especially when it is often placed in a pocket or bag, it is easy to rub against hard objects such as keys and coins, resulting in wear and scratches. Film coating can effectively prevent such wear and maintain the beauty and durability of the mobile phone case.

[0003] However, the following defects exist in the specific use of the mobile phone case film coating mechanism:

[0004] 1. When the existing mobile phone case film coating mechanism attaches the film to the surface of the mobile phone case, it is necessary to first place the film on the back of the mobile phone case, and then attach the film to the mobile phone case by extrusion and heating. However, when actually attaching the film to the mobile phone case, in order to reduce the probability of film displacement, the traditional extrusion method is prone to generate more bubbles when extruding the film. And it is easy to cause the problem of unidirectional stress concentration in the adhesive layer of the film, affecting the stress distribution balance of the film adhesive layer;

[0005] 2. When the existing mobile phone case film coating mechanism adheres the film, it is necessary to separately place the film, shape and adhere the film, and perform subsequent leveling and shaping. Therefore, the cooperation of multiple structures is required to complete the entire film adhesion operation. However, when the traditional device completes the above operations, the floor area of the device is large, it is difficult to disassemble the mobile phone case after film coating, and it is easy to damage the film part of the mobile phone case during disassembly, affecting the quality of the mobile phone case after film coating.

[0025] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0026] 1. In the curved laminating mechanism for concave and convex three-dimensional mobile phone cases, the laminating sheet with adjustable oblique angle can, when the film is adhered to the surface of the mobile phone case, on the one hand, the shear force generated by oblique pressure can more effectively push the air to the edge of the film and the mobile phone case, optimizing the efficiency of removing internal bubbles when the film is adhered to the mobile phone case. On the other hand, oblique pressure provides more angle adjustment space. When a slight offset occurs, dynamic compensation can be made within the range of 1 to 2 mm by changing the extrusion angle, reducing the scrap rate of the film. In addition, when the film is adhered by oblique extrusion, the film can produce directional extension and deformation, which better fits the shape of the screen curve. It can also avoid the problem of unidirectional stress concentration in the film adhesive layer, ensuring the distribution of stress in the film adhesive layer is balanced.

[0027] 2. In the curved laminating mechanism for concave and convex three-dimensional mobile phone cases, the film can be adsorbed (via a vacuum suction cup), the film and mobile phone case are attached, the film and mobile phone case are squeezed and adhered, and the film and mobile phone case are flattened, according to the order of film operation, to achieve automated film and mobile phone case adhesion. In addition, the vacuum suction cup that adsorbs the film can serve as an extrusion positioning part for the mint mobile phone case during the extrusion and adhesion operation, reducing the extrusion force during the extrusion and adhesion process that may cause the film to deflect or bend, ensuring that the film can be completely adhered to the surface of the mobile phone case.

[0028] 3. In the curved laminating mechanism for concave-convex three-dimensional mobile phone cases, by providing curved surfaces on the front and back sides of the bottom of the laminating sheet, when the laminating sheet moves obliquely to adhere the film to the surface of the mobile phone case, on the one hand, the contact area between the laminating sheet and the film is increased, thereby reducing the probability of a large number of empty bags being generated on the mobile phone case during the adhesion of the film. On the other hand, the film can be evenly stressed, reducing the probability of deformation of the film during adhesion, and enhancing the ability of the film to adhere completely and maintain its original shape, thereby improving the laminating effect of the film.

[0029] 4. In the curved laminating mechanism for convex and concave phone cases, after the film laminating operation is completed, the rotary drive source is activated to operate, moving the mold insert block that holds the phone case to the outside of the laminating mold, automatically completing the phone case demolding operation. This improves the convenience of phone case demolding while preventing damage to the laminating side of the phone case, ensuring the aesthetics and quality of the phone case after demolding. Furthermore, during demolding and resetting (mold insert block), buffer springs ensure that each component accurately returns to its initial position, facilitating the continued laminating operation of the phone case. It also balances the forces between the various components, ensuring normal and stable demolding. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0056] Embodiment 1

[0057] Please refer to Figures 1 - 12 , the curved surface film laminating mechanism for the concave-convex three-dimensional mobile phone case includes a frame 10 and a mobile phone shell 30; an automatic film laminating and leveling structure 20 installed on the top of the frame 10 by screws; a film laminating lower mold 40 arranged at the bottom of the automatic film laminating and leveling structure 20 and on the side of the frame 10, with a mobile phone shell 30 installed inside the film laminating lower mold 40; an automatic demolding assembly 50 installed inside the film laminating lower mold 40 and extending to the bottom of the film laminating lower mold 40. The automatic film laminating and leveling structure 20 includes: a slide rail assembly 201 installed on the top of the frame 10 by screws; a compensation lifting assembly 202 installed at the center inside the slide rail assembly 201; a plurality of vacuum suction cups 203 installed at the bottom corners of the slide rail assembly 201; a movable block 204 rotatably connected to the center of the bottom of the compensation lifting assembly 202; a film laminating sheet 205 installed at the bottom of the movable block 204 by screws; a film laminating adjustment assembly 206 connected to the movable block 204 and installed at the bottom of the compensation lifting assembly 202; a film laminating leveling assembly 207 installed inside the slide rail assembly 201 and on the side of the compensation lifting assembly 202.

[0058] The above working principle is as follows: when the film is adhered to the surface of the mobile phone housing 30, the cut corner portion of the film is vacuum-adsorbed by the vacuum suction cup 203, and the film is placed on the top of the mobile phone housing 30 by starting the slide rail assembly 201. After that, the compensation lifting assembly 202 is started to operate, driving the film sheet 205 to lift and move horizontally, and while contacting the film, the film is squeezed obliquely to complete the adhesion operation of the connecting part. After completing the adhesion operation of a part of the film, the vacuum suction cup 203 is closed, and the position (horizontal direction) of the film sheet 205 is adjusted by starting the compensation lifting assembly 202, and the film that is not adhered (half of the total area) is adsorbed and the corresponding adhesion operation is performed, thereby completing the entire adhesion operation of the mobile phone housing 30. Among them, when the film is adhered, the angle of the coating sheet 205 can be adjusted (about 30 degrees to 45 degrees) by driving the movable block 204 and the coating sheet 205 to rotate through the coating adjustment component 206. The shear force generated by the oblique pressure can more effectively push the air to move toward the edge in a directional manner, thereby optimizing the efficiency of removing bubbles inside the film when the film is adhered. At the same time, for the 3D arc structure of the curved screen, the oblique extrusion can cause the film to produce a directional extension and deformation, which is more in line with the curved surface shape of the screen.

[0059] In the present invention, after the film adhesion operation is completed, the film leveling assembly 207 and the slide rail assembly 201 can be started to operate to level the mobile phone housing 30 on which the film adhesion operation is completed, thereby ensuring the aesthetics and quality of the mobile phone housing 30.

[0078] During use, it is found that when the film laminating piece 205 adheres the film to the mobile phone shell 30, since it is in a state of simulating manual film lamination operation, at this time the film laminating piece 205 generally presses down the film at an angle of 30 degrees. However, in the actual operation of the above operation, the inclined angle of the film laminating piece 205 and the contact area of the film are small, which is likely to cause a large number of air pockets on the mobile phone shell 30 during film lamination, affecting the quality of the mobile phone shell 30 after film lamination.

[0079] Therefore, specifically referring to Figure 12 Figure 13 , the front and rear sides of the bottom of the film laminating piece 205 are set as arc surfaces 60, and an internal heating module 601 is assembled at the center inside the film laminating piece 205. The internal heating module 601 is connected to the battery module 602 through a wire, and the battery module 602 is installed on the top of the film laminating piece 205.

[0080] In the curved surface film laminating mechanism for the concave-convex three-dimensional mobile phone case of the present invention, through the design of the arc surfaces 60 on the front and rear sides of the film laminating sheet 205, when the film laminating sheet 205 is in an inclined state of 30 degrees to 45 degrees, the contact area between the film laminating sheet 205 and the film can be increased, the probability of generating a large number of empty packages on the mobile phone shell 30 during film adhesion can be reduced, and the quality of the mobile phone shell 30 after film lamination can be improved. At the same time, during the film adhesion operation, the film can be uniformly stressed, the probability of the film deforming during adhesion can be reduced, and its ability to maintain its original shape can be enhanced.

[0081] Therefore, any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
