Description

Technical Field

[0001] This invention relates to the field of coating structure technology, specifically to a curved surface coating mechanism for three-dimensional mobile phone cases with concave and convex surfaces. Background Technology

[0002] Phone cases protect phones from direct damage when dropped or subjected to external impacts, especially when dropped, as they act as a cushion to reduce the force of the fall. However, over time, especially when frequently kept in pockets or bags, phone cases are prone to wear and scratches from friction with hard objects like keys and coins. A protective film can effectively prevent this wear and tear, maintaining the phone case's appearance and durability.

[0003] However, this phone case coating mechanism has the following drawbacks in actual use:

[0004] 1. Existing mobile phone case coating mechanisms require placing the film on the back of the phone case first, then adhering it to the case through compression and heating. However, in practice, the traditional compression method, in an effort to reduce film displacement, tends to generate numerous air bubbles. Furthermore, it can lead to unidirectional stress concentration in the adhesive layer, affecting the balanced stress distribution within the adhesive layer.

[0005] 2. Existing mobile phone case coating mechanisms require separate steps for film placement, shaping, and adhesion, as well as subsequent leveling and shaping, necessitating the coordination of multiple structures to complete the entire film adhesion process. However, traditional devices occupy a large area, making it difficult to disassemble the coated phone case and easily damaging the film portion during disassembly, thus affecting the quality of the coated phone case. Summary of the Invention

[0025] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0026] 1. In the curved surface coating mechanism for textured mobile phone cases, the adjustable-angle coating sheet allows for more efficient airflow towards the edges of the film and phone case during film adhesion. This is achieved through shearing force generated by the angled pressure, optimizing the removal of air bubbles during film adhesion. Furthermore, the angled pressure provides greater flexibility for angle adjustment. Minor deviations can be dynamically compensated within a 1-2mm range by changing the extrusion angle, reducing the scrap rate of the film. Additionally, the angled extrusion during film adhesion causes directional stretching deformation, better conforming to the curved surface of the screen and preventing unidirectional stress concentration in the adhesive layer, ensuring a balanced stress distribution.

[0027] 2. In the curved surface coating mechanism for textured phone cases, the film adsorption (via vacuum suction cup), film-phone case bonding, film-phone case extrusion bonding, and film-phone case leveling can be performed sequentially according to the film application order, achieving automated film-phone case bonding. Furthermore, the vacuum suction cup adsorbing the film can act as a positioning component during the film-phone case extrusion bonding process, reducing pressure during bonding that could cause film displacement or bending, ensuring the film adheres completely to the phone case surface.

[0028] 3. In the curved surface coating mechanism for three-dimensional mobile phone cases with concave and convex shapes, by setting arc-shaped surfaces on the front and rear sides of the bottom of the coating sheet, when the coating sheet moves obliquely to adhere the film to the surface of the mobile phone case, on the one hand, it increases the contact area between the coating sheet and the film, reducing the probability of a large number of empty cavities on the mobile phone case during film adhesion; on the other hand, it enables the film to 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 coating effect.

[0029] 4. In the curved surface coating mechanism for embossed phone cases, after the film coating process is completed, the mold insert block for mounting and positioning the phone case can be moved to the outside of the coating mold by activating the rotary drive source. This automatically completes the demolding operation of the phone case, improving the ease of demolding without damaging the coated side, ensuring the aesthetics and quality of the demolded phone case. Furthermore, during demolding and resetting (of the mold insert block), buffer springs ensure that each component accurately returns to its initial position, facilitating continuous coating operations and balancing the forces between components, ensuring normal and stable demolding.

[0055] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0056] Example 1

[0057] Please see Figures 1-12 The curved surface coating mechanism for a textured mobile phone case includes a frame 10 and a mobile phone case 30; an automated coating and leveling structure 20 mounted on top of the frame 10 by screws; a lower coating mold 40 located at the bottom of the automated coating and leveling structure 20 and on the side of the frame 10, with the mobile phone case 30 installed inside the lower coating mold 40; and an automated demolding assembly 50 installed inside the lower coating mold 40 and extending to the bottom of the lower coating mold 40. The automated coating and leveling structure 20 includes a slide rail assembly mounted on top of the frame 10 by screws. 201; Compensation lifting assembly 202 installed at the center of the slide rail assembly 201; Multiple vacuum suction cups 203 installed at the bottom corner of the slide rail assembly 201; Movable block 204 rotatably connected to the center of the bottom of the compensation lifting assembly 202; Film covering sheet 205 installed at the bottom of the movable block 204 by screws; Film covering adjustment assembly 206 connected to the movable block 204 and installed at the bottom of the compensation lifting assembly 202; Film covering leveling assembly 207 installed inside the slide rail assembly 201 and located on the side of the compensation lifting assembly 202.

[0058] The working principle is as follows: When the film is adhered to the surface of the mobile phone casing 30, the vacuum suction cup 203 vacuum-adsorbs the corner portion of the cut film, and the sliding rail assembly 201 is activated to place the film on top of the mobile phone casing 30. Then, the compensation lifting assembly 202 is activated, causing the film sheet 205 to move up, down, and horizontally, pressing the film at an angle while it comes into contact with it, thus completing the adhesion operation of the connecting part. After a portion of the film is adhered, the vacuum suction cup 203 is turned off, and the position (horizontal direction) of the film sheet 205 is adjusted by activating the compensation lifting assembly 202 to adsorb and adhere the unattached film (half of the total area), thereby completing the adhesion operation of the entire mobile phone casing 30. During the film adhesion process, the angle of the film 205 (approximately 30 to 45 degrees) can be adjusted by rotating the movable block 204 and the film 205 through the film adjustment component 206. The shearing force generated by the oblique pressure can more effectively push the air to move directionally towards the edge, optimizing the efficiency of removing air bubbles during film adhesion. At the same time, for the 3D curved structure of the curved screen, the oblique extrusion can cause the film to undergo directional stretching deformation, which better fits the curved shape of the screen.

[0059] In this invention, after the film adhesion operation is completed, the mobile phone casing 30 can be leveled by activating the film leveling component 207 and the slide rail component 201 to ensure the aesthetics and quality of the mobile phone casing 30.

[0060] For details, please refer to the following: Figure 7 The slide rail assembly 201 includes: a horizontal slide rail 2011 mounted on the top of the frame 10 by screws; a horizontal electric slider 2012 movably disposed outside the horizontal slide rail 2011; an upper bracket 2013 mounted on the top of the horizontal electric slider 2012 by screws; a longitudinal slide rail 2014 mounted on the inner side of the upper bracket 2013 by screws; a longitudinal electric slider 2015 movably disposed outside the longitudinal slide rail 2014; and an I-shaped steel plate 2016 mounted on the side of the longitudinal electric slider 2015 by screws. Two horizontal slide rails 2011 and two horizontal electric sliders 2012 are provided, and the upper bracket 2013 is configured as a semi-enclosed "L" shape.

[0061] In this solution, a side mounting plate 20161 is screwed onto the bottom of the I-shaped steel plate 2016. Side positioning plates 20162 are screwed onto both working sides of the side mounting plate 20161. An assembly block 20163 is screwed onto the inner side of the side positioning plate 20162. A lower base plate 20164 is screwed onto the outer side of the assembly block 20163. A recess 201641 is formed on one side of the lower base plate 20164. A compensation lifting assembly 202 is movably disposed inside the recess 201641. A film-coating leveling assembly 207 located on the side of the recess 201641 is installed inside the lower base plate 20164. The edges on both sides of the top of the lower base plate 20164 protrude upwards and form upper protrusions 201642. The compensation lifting assembly 202 is slidably connected inside the upper protrusions 201642.

[0062] In the curved surface coating mechanism for a textured mobile phone case of the present invention, the I-beam steel plate 2016 can be moved horizontally by the horizontal electric slider 2012 moving outside the horizontal slide rail 2011, and the I-beam steel plate 2016 can be moved vertically by the longitudinal electric slider 2015 moving outside the longitudinal slide rail 2014. The design of the I-beam steel plate 2016, the side positioning plate 20162, and the assembly block 20163 improves the load-bearing capacity and service life in both horizontal and vertical directions.

[0063] For details, please refer to the following: Figure 5 , Figure 6 , Figure 8 and Figure 9 The compensation lifting assembly 202 includes: a linear drive source 2021 installed at the center inside the lower base plate 20164 and located on the side of the recess 201641; a back metal plate 2022 connected to the output end of the linear drive source 2021; an upper base 2023 installed on the top of one side of the back metal plate 2022 by screws; a vertical drive source 2024 installed at the center of the top of the upper base 2023; and an L-shaped base plate 2025 connected to the output end of the vertical drive source 2024, wherein the two sides of the bottom of the upper base 2023 protrude downward and are slidably connected to the horizontal groove 20231 opened inside the upper protrusion 201642.

[0064] In this design, a horizontal slide block 20221 is installed at the bottom of one side of the back metal plate 2022. The output end of the vertical drive source 2024 passes through the horizontal slide block 20221. The horizontal slide block 20221 is slidably connected to the side of the horizontal rod 20222. The horizontal rod 20222 is installed inside the recess 201641 and extends to the outside of the recess 201641. An L-shaped base plate 2025 is provided at the bottom of the horizontal slide block 20221. The included angle at the top of the L-shaped base plate 2025 is slidably connected to the horizontal slide block 20221 through a vertical guide rod 20251. A movable block 204 is rotatably connected at the center of the bottom of the L-shaped base plate 2025. Film-coating adjustment components 206 located on the left and right sides of the movable block 204 are installed at the bottom of the L-shaped base plate 2025.

[0065] In the curved surface coating mechanism for a textured mobile phone case of the present invention, when the bottom of the coating sheet 205 needs to contact the film, the vertical drive source 2024 is activated to drive the L-shaped base plate 2025 and the coating sheet 205 connected to the output end of the vertical drive source 2024 to move up and down, approaching the film for a preparatory operation of adhesion. When the coating sheet 205 is driven to perform a horizontal film adhesion operation, the linear drive source 2021 is activated to drive the upper base 2023, the vertical drive source 2024, the L-shaped base plate 2025 and the coating sheet 205 connected to the output end of the linear drive source 2021 to move horizontally, realizing the film adhesion operation. Among them, when the upper base 2023 moves horizontally, the protruding parts provided on both sides of its bottom will move within the horizontal groove 20231 inside the upper protrusion 201642, guiding the horizontal movement of the upper base 2023.

[0066] In this invention, the vertical drive source 2024 and the linear drive source 2021 are preferably servo electric cylinders.

[0067] For details, please refer to the following: Figure 9 and Figure 10 The film-coating adjustment assembly 206 includes: a lower connecting seat 2061 mounted on the bottom of the L-shaped base plate 2025 by screws; a bottom block 2062 rotatably connected to the inner side of the lower connecting seat 2061; an oblique drive source 2063 mounted on the side of the bottom block 2062 by screws; and a movable head 2064 rotatably connected to the output end of the oblique drive source 2063, wherein a movable block 204 is mounted on the inner side of the movable head 2064.

[0068] In the curved surface coating mechanism for a textured mobile phone case of the present invention, when the angle of the coating sheet 205 is adjusted to achieve a better film adhesion, the oblique drive source 2063 is activated, which drives the movable head 2064 connected to the output end of the oblique drive source 2063 to operate, causing the movable block 204 and the coating sheet 205 mounted on the inner side of the movable head 2064 to rotate, thereby adjusting the angle of the coating sheet 205 (from 30 degrees to 45 degrees).

[0069] In this invention, the oblique drive source 2063 is preferably a linear cylinder.

[0070] For details, please refer to the following: Figure 8 The coating and leveling assembly 207 includes: a lifting drive source 2071 mounted on the top of the lower substrate 20164; a lifting plate 2072 connected to the output end of the lifting drive source 2071 and slidably connected to the lower substrate 20164; and a leveling piece 2073 mounted on the bottom of the lifting plate 2072 by screws.

[0071] In the curved surface coating mechanism for a textured mobile phone case of the present invention, after the film and mobile phone case 30 are bonded together, the lifting drive source 2071 is activated to move the lifting plate 2072 and the leveling plate 2073 connected to the output end to move up and down, so that the leveling plate 2073 abuts against the top of the mobile phone case 30. Then, by moving the leveling plate 2073 horizontally, the mobile phone case 30 after the film bonding is completed is leveled, thereby improving the aesthetics and quality of the mobile phone case 30.

[0072] In this invention, the lifting drive source 2071 is preferably a lifting electric cylinder.

[0073] For details, please refer to the following: Figure 11 and Figure 12 The automated demolding assembly 50 includes: a lower pad 501 mounted on the bottom of the undercoating mold 40 by screws; support seats 502 mounted on both sides of the bottom of the lower pad 501 by screws; a lower base plate 504 mounted on the inner side of the support seats 502 by a locking block 503; a rotary drive source 505 mounted on the bottom of the lower base plate 504; a reciprocating screw 506 connected to the output end of the rotary drive source 505 and rotatably connected to the center of the bottom of the lower pad 501; a lifting demolding plate 507 connected to the outside of the reciprocating screw 506 by ball bearings; a demolding rod 508 mounted at the top angle of the lifting demolding plate 507 and extending into the interior of the undercoating mold 40; and a mold insert block 509 connected to the demolding rod 508 and disposed inside the undercoating mold 40, wherein a mobile phone casing 30 is fitted on the top of the mold insert block 509.

[0074] In this design, a linear guide rod 5071 located on the side of the demolding rod 508 is slidably connected at the center of the top edge of the lifting demolding template 507. The linear guide rod 5071 is installed at the bottom of the lower pad 501, and a buffer spring 5072 is provided on the outside of the linear guide rod 5071 between the lower pad 501 and the lifting demolding template 507.

[0075] In the curved surface coating mechanism for a three-dimensional mobile phone case of the present invention, after the flattening operation of the mobile phone case 30 is completed, the rotary drive source 505 is activated to drive the reciprocating screw 506 connected to its output end to rotate, and the lifting demolding platen 507 and demolding rod 508 connected to the outside of the reciprocating screw 506 via ball bearings move up and down. At this time, when the demolding rod 508 moves up and down, it drives the mold insert block 509 installed on its top to move up and down, and causes the mobile phone case 30 installed outside the mold insert block 509 to move up and down, removing the mobile phone case 30 from the inside of the coating mold 40, completing the demolding operation of the mobile phone case 30. During the demolding operation, the lifting demolding platen 507 compresses the buffer spring 5072, and the elasticity of the buffer spring 5072 helps each component of the automated demolding assembly 50 to accurately reset after each use, facilitating the continuous demolding and adhesion operation of the mobile phone case 30, and ensuring the stability and reliability of the automated demolding assembly 50 during operation.

[0076] In this invention, the rotation drive source 505 is preferably a rotary motor.

[0077] Example 2

[0078] During use, it was found that when the film-applying sheet 205 attaches the film to the phone casing 30, simulating manual film application, the sheet is typically tilted at a 30-degree angle to press the film down. However, in actual operation, the small contact area between the angled sheet 205 and the film easily leads to numerous empty spaces on the phone casing 30, affecting the quality of the coated phone casing 30.

[0079] For specific reference Figure 13 The front and rear sides of the bottom of the film sheet 205 are set as arc surfaces 60. An internal heating module 601 is installed in the center of the film sheet 205. The internal heating module 601 is connected to the battery module 602 through wires. The battery module 602 is installed on the top of the film sheet 205.

[0080] In the curved surface coating mechanism for a textured three-dimensional mobile phone case of the present invention, the design of the arc-shaped surfaces 60 on both the front and rear sides of the coating sheet 205 increases the contact area between the coating sheet 205 and the film when the coating sheet 205 is tilted at 30 to 45 degrees. This reduces the probability of a large number of empty spaces being generated on the mobile phone case 30 during film adhesion, thus improving the quality of the coated mobile phone case 30. Simultaneously, during the film adhesion process, the film can be subjected to uniform force, reducing the probability of deformation during adhesion and enhancing its ability to maintain its original shape.

[0081] Therefore, any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this invention, based on the technical solution and inventive concept of this invention, should be covered within the protection scope of this invention.
