Description

Technical Field

[0001] This invention relates to the field of film application equipment technology, and more specifically, to a film application device and method for 3D curved glass. Background Technology

[0002] Mobile phone displays have long since evolved from the single flat design of the past to the current 3D mobile phone screens. In the past, mobile phone screen glass was mostly flat, and the screen protector application process only required rolling and pressing the screen protector to complete the application. With the advent of 3D curved glass, achieving screen protector application in one station, or achieving screen protector application in one station more efficiently, has become a current production challenge.

[0003] Currently, existing 3D curved glass film application equipment often suffers from the following technical problems during use:

[0004] The surface of the bonding roller in existing 3D curved glass film application equipment cannot effectively bond with the side curved surface of the 3D curved glass, causing the film to lift off the side curved surface of the 3D curved glass after application, reducing the bonding effect between the film and the side curved surface of the 3D curved glass. In addition, when positioning and fixing 3D curved glass of different sizes, existing 3D curved glass film application equipment often requires changing the positioning structure according to the actual size of the 3D curved glass, which reduces the film application efficiency and brings certain inconveniences to the subsequent film application process. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a film-applying device and method for 3D curved glass that improves the adhesion between the film and the side curved surface of 3D curved glass, prevents the film from lifting off the side curved surface, and can fix the positioning of 3D curved glass of different sizes to be filmed, preventing it from shifting during the subsequent film application process. Furthermore, it eliminates the need for frequent changes to the positioning structure based on the size of the 3D curved glass to be filmed, thus bringing convenience to the subsequent film application process.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A film-applying device for 3D curved glass includes a portable case with a lid hinged to the top and a film-applying assembly slidably fitted inside the case.

[0008] The film application assembly includes a positioning component, a displacement component is fixedly connected to the positioning component, and two symmetrical film application components are slidably fitted inside the displacement component.

[0009] The displacement component includes a lower pressure plate, a U-shaped plate is fixed to the bottom of the lower pressure plate, and two symmetrical guide grooves are opened on the top of the lower pressure plate.

[0010] The film-applying component includes two symmetrical sliders, with a U-shaped base plate fixed to the bottom of each slider. A rotating shaft is fixed to the inner wall of the U-shaped base plate. Two symmetrical rotating plates are rotatably fitted to the circumferential side of the rotating shaft. A positioning shaft is fixed between the two rotating plates. An applicating roller is rotatably fitted to the circumferential side of the positioning shaft. An arc-shaped spring is fixed between the rotating plate and the U-shaped base plate. The sliders are slidably fitted with guide grooves.

[0011] The invention is further configured such that: a guide rod is fixed to the inner wall of one of the guide grooves, and a bidirectional threaded rod is rotatably fitted inside the other guide groove.

[0012] A servo motor is fixed to one side of the lower pressure plate, and the output shaft of the servo motor is fixedly connected to a bidirectional threaded rod.

[0013] One slider has a threaded hole on one side, and the other slider has a guide hole on one side. The bidirectional threaded rod is threadedly connected to the threaded hole, and the guide hole is slidably engaged with the guide rod.

[0014] The invention is further configured such that: a telescopic rod is fixed to the top of the lower pressure plate, and a connecting flange is fixed to the top of the telescopic rod.

[0015] The positioning component includes a connecting plate, the top of which has several connecting holes, and the connecting holes are fixedly connected to the connecting flange by bolts.

[0016] The invention is further configured such that: the positioning component also includes a lifting plate, two symmetrical U-shaped guide frames are fixed to the top of the lifting plate, a support plate is fixed to one side of each of the two U-shaped guide frames near the top, a U-shaped support top plate is fixed to the top of the support plate, a through hole is provided on the top of the support plate below the U-shaped support top plate, and an electric rod is fixed to the top of the U-shaped support top plate.

[0017] Both U-shaped guide frames have L-shaped plates that slide inside them, and the tops of both L-shaped plates are fixedly connected to the bottom of the connecting plate.

[0018] The invention is further configured such that: a first hinge seat is fixed to the bottom of each of the two L-shaped plates, a hinge arm is hinged to the inside of the first hinge seat, a second hinge seat is hinged to the opposite sides of the hinge arm, a positioning plate is fixed to the bottom of the second hinge seat, and a protective pad is fixed to one side of the positioning plate.

[0019] A U-shaped mounting plate is fixed to the top of the lifting plate. The U-shaped mounting plate has convex grooves on both sides. The second hinge seat and the positioning plate slide in sequence with the convex grooves.

[0020] The invention is further configured such that a plurality of sliding holes are provided through the top of the lifting plate.

[0021] The bottom of the portable case is fixed with several guide posts, which slide in conjunction with sliding holes.

[0022] The invention is further configured such that: two symmetrical limiting round rods are fixed on each of the two inner sidewalls of the portable case, and a U-shaped baffle is slidably fitted between the two limiting round rods.

[0023] A rotating motor is fixed to one outer side of the portable case near the bottom. A threaded screw is fixed to the output shaft of the rotating motor. The threaded screw is rotatably connected to a U-shaped baffle. The threaded screw passes through one outer side of the portable case and is rotatably engaged with the portable case.

[0024] The invention is further configured such that: a third hinge seat is fixed at the center of the bottom of the U-shaped baffle, a lifting arm is hinged inside the third hinge seat, and a hinge hole is provided on one side of the lifting arm.

[0025] The bottom of the lifting plate is fixed with a fourth hinge seat, which is hinged to the hinge hole.

[0026] The present invention is further configured to include the following method steps:

[0027] T1. Before applying the film, open the lid that is hinged to the top of the portable case, and then start the rotating motor so that the U-shaped baffle slides to the right inside the portable case.

[0028] T2. When the U-shaped baffle slides to the right inside the portable case, the lifting arm, which is hinged between the third and fourth hinge seats, will lift relative to each other, thereby driving the lifting plate to slide upward inside the portable case until the lifting plate slides out of the portable case. Then, the rotating motor is turned off, and the subsequent 3D curved glass film application is carried out.

[0029] Before applying the film to T3 and 3D curved glass, the 3D curved glass to be filmed is placed stably inside the positioning component for positioning and fixation. During the positioning and fixation process, the two electric rods are activated, causing the electric rods to extend and retract inside the perforation.

[0030] T4. When the telescopic ends of the two electric rods extend and retract, they cause the hinge arms that are hinged between the first and second hinge seats to press down or lift, thereby providing a left-right relative force to the positioning plates. Ultimately, this causes the two opposing positioning plates to move closer or further apart within the convex groove until the protective pads on one side of the two positioning plates come into contact with both sides of the 3D curved glass to be coated, at which point the two electric rods are closed.

[0031] T5. After positioning and fixing, simultaneously start the telescopic rod, which will drive the lower pressure plate fixed at the bottom of the telescopic rod to move downwards until the outer bottom of the U-shaped plate is in contact with the film surface of the 3D curved glass to be filmed. Then close the telescopic rod to complete the positioning and fixing of 3D curved glass of different sizes to be filmed, and prevent it from shifting during the subsequent film application process.

[0032] T6. After the preparation work in T1 to T5 is completed, start the servo motor and drive the bidirectional threaded rod fixed to the output shaft of the servo motor to rotate, so that the two film-applying parts are separated from each other in the two guide grooves respectively.

[0033] T7. When the film-applying components are moving away from each other inside the two guide grooves, in the initial state before they move away, both film-applying components are inside the U-shaped plate. At this time, the arc spring connected and fixed between the rotating plate and the U-shaped base plate is in a compressed state.

[0034] T8. As the two film-applying components gradually slide out from inside the U-shaped plate, the compressed arc spring begins to reset, causing the rotating plate to press down and rotate on the circumferential side of the rotating shaft until the bonding roller, which is in circumferential contact with the film surface on the 3D curved glass to be coated, comes into contact with each other. Then, the two film-applying components continue to move away from each other.

[0035] T9. As the two film-applying components continue to move away from each other, their bonding rollers contact the film surface on the 3D curved glass to be coated. Then, through the subsequent rolling action of the bonding rollers, the film is effectively applied to the side curved surface of the 3D curved glass, improving the bonding effect between the film and the side curved surface of the 3D curved glass and preventing the film from lifting off the side curved surface.

[0036] The advantages of this invention are:

[0037] 1. This invention involves two film-applying components sliding out from inside the U-shaped base plate, causing the compressed arc-shaped spring to return to its original position. This causes the rotating plate to rotate downwards on the circumferential side of the rotating shaft until the applying roller contacts the film surface on the 3D curved glass to be coated. After this, the two film-applying components continue to move away from each other. In this way, the contact between the applying roller and the film surface on the 3D curved glass to be coated, along with the subsequent rolling action, effectively applies the film to the side curved surface of the 3D curved glass, improving the adhesion effect between the film and the side curved surface of the 3D curved glass and preventing the film from lifting off the side curved surface.

[0038] 2. This invention activates an electric rod, causing its telescopic end to extend and retract. During this extension and retraction, the hinge arm connecting the first and second hinge seats presses down or lifts, providing a left-right relative force to the positioning plates. This force causes the two opposing positioning plates to move closer or further apart within the convex groove until the protective pads on one side of the two positioning plates contact the two sides of the 3D curved glass to be coated. This completes the positioning and fixing of 3D curved glass of different sizes. During use, there is no need to frequently change the positioning structure according to the size of the 3D curved glass, bringing convenience to the subsequent coating process.

[0052] Example 1

[0053] Please see Figure 1-9 The present invention provides the following technical solutions:

[0054] A film-applying device for 3D curved glass, specifically comprising a portable case 1, with a case lid 101 hinged to the top of the case 1, and a film-applying assembly 2 slidably fitted inside the case 1; the film-applying assembly 2 includes a positioning member 3, a displacement member 4 fixedly connected to the positioning member 3, and two symmetrical film-applying components 5 slidably fitted inside the displacement member 4; the displacement member 4 includes a lower pressure plate 401, a U-shaped plate 402 fixed to the bottom of the lower pressure plate 401, and two symmetrical guide grooves 403 formed on the top of the lower pressure plate 401; the film-applying component 5 includes two symmetrical sliders 501, a U-shaped base plate 502 fixed to the bottom of the two sliders 501, a rotating shaft 503 fixed to the inner wall of the U-shaped base plate 502, and two symmetrical rotating plates 504 rotatably fitted around the circumference of the rotating shaft 503. A positioning shaft 505 is fixed between the rotating plates 504. A bonding roller 506 is rotatably fitted to the circumferential side of the positioning shaft 505. An arc spring 507 is fixed between the rotating plates 504 and the U-shaped base plate 502. The slider 501 is slidably fitted to the guide groove 403. A guide rod 404 is fixed to the inner wall of one guide groove 403, and a bidirectional threaded rod 405 is rotatably fitted inside the other guide groove 403. A servo motor 406 is fixed to one side of the lower pressure plate 401. The output shaft of the servo motor 406 is fixedly connected to the bidirectional threaded rod 405. A threaded hole 508 is opened on one side of one slider 501, and a guide hole 509 is opened on one side of the other slider 501. The bidirectional threaded rod 405 is threadedly connected to the threaded hole 508, and the guide hole 509 is slidably fitted to the guide rod 404.

[0055] The specific application of this embodiment is as follows: When it is necessary to apply a film to the 3D curved glass to be coated, open the hinged lid 101 at the top of the carrying case 1 and then slide the film application component 2 out of the carrying case 1, so that the film application component 2 is located outside the carrying case 1. At this time, place the 3D curved glass to be coated smoothly inside the positioning component 3 for positioning and fixing. After fixing, move the U-shaped plate 402 fixed at the bottom of the lower pressure plate 401 to the top of the 3D curved glass to be coated, and at the same time make the outer bottom of the U-shaped plate 402 contact the surface of the 3D curved glass to be coated. Then, start the servo motor 406, which drives the bidirectional threaded rod 405 fixed to the output shaft of the servo motor 406 to rotate inside another guide groove 403. During the rotation, through the threaded connection between the bidirectional threaded rod 405 and the two threaded holes 508 and the sliding cooperation between the two guide holes 509 and the guide rod 404, the two film application components 5 are respectively in the two guide grooves 403. As the film-applying parts gradually move away from each other, and the two film-applying parts 5 are initially positioned inside the U-shaped plate 402, the arc-shaped spring 507, which is connected and fixed between the rotating plate 504 and the U-shaped base plate 502, is compressed. Subsequently, as the two film-applying parts 5 gradually slide out from inside the U-shaped plate 402, the compressed arc-shaped spring 507 begins to reset, causing the rotating plate 504 to rotate downwards on the circumferential side of the rotating shaft 503. Until the bonding roller 506, which rotates around the positioning shaft 505, comes into contact with the film surface on the 3D curved glass to be coated, the two coating parts 5 continue to move away from each other. In this way, through the contact between the bonding roller 506 and the film surface on the 3D curved glass to be coated, the subsequent rolling action of the bonding roller 506 effectively coats the side curved surface of the 3D curved glass, improves the bonding effect between the film and the side curved surface of the 3D curved glass, and prevents the film from lifting off the side curved surface.

[0056] Example 2

[0057] Please see Figure 1-9This second embodiment is an improvement on the first embodiment as follows: Specifically, a telescopic rod 407 is fixed to the top of the lower pressure plate 401, and a connecting flange 408 is fixed to the top of the telescopic rod 407; the positioning component 3 includes a connecting plate 301, the top of which has several connecting holes 302, and the connecting holes 302 are fixedly connected to the connecting flange 408 by bolts; the positioning component 3 also includes a lifting plate 303, the top of which has two symmetrical U-shaped guide frames 304, and a support plate 305 is fixed to one side of each of the two U-shaped guide frames 304 near the top, and a U-shaped support is fixed to the top of the support plate 305. A top support plate 306 and a support plate 305 are provided with a through hole 307 located below the U-shaped top support plate 306. An electric rod 308 is fixed inside the top of the U-shaped top support plate 306. L-shaped plates 309 are slidably fitted inside both U-shaped guide frames 304, and the tops of both L-shaped plates 309 are fixedly connected to the bottom of the connecting plate 301. A first hinge seat 310 is fixed to the bottom of each of the two L-shaped plates 309. A hinge arm 311 is hinged inside the first hinge seat 310, and a second hinge seat 312 is hinged to the opposite sides of the hinge arm 311. A positioning plate 313 is fixed to the bottom of the second hinge seat 312 for positioning. A protective pad 314 is fixed to one side of the plate 313; a U-shaped mounting plate 315 is fixed to the top of the lifting plate 303, and convex grooves 316 are opened on both opposite sides of the U-shaped mounting plate 315. The second hinge seat 312 and the positioning plate 313 are slidably engaged with the convex grooves 316 in sequence; several sliding holes 317 are opened through the top of the lifting plate 303; several guide posts 102 are fixed to the bottom of the inner side of the portable case 1, and the guide posts 102 are slidably engaged with the sliding holes 317; two symmetrical limiting round rods 103 are fixed to both opposite inner side walls of the portable case 1, and a U-shaped baffle 104 is slidably engaged between the two limiting round rods 103; one outer side of the portable case 1 A rotating motor 105 is fixed near the bottom of the side. A threaded screw 106 is fixed to the output shaft of the rotating motor 105. The threaded screw 106 is threadedly rotatably connected to the U-shaped baffle 104. The threaded screw 106 passes through one outer side of the portable case 1 and is rotatably engaged with the portable case 1. A third hinge seat 107 is fixed at the center of the bottom of the U-shaped baffle 104. A lifting arm 108 is hinged inside the third hinge seat 107. A hinge hole 109 is opened on one side of the lifting arm 108. A fourth hinge seat 318 is fixed at the bottom of the lifting plate 303. The fourth hinge seat 318 is hinged to the hinge hole 109.

[0058] The specific application of this embodiment two is as follows: Before the film application operation, the rotating motor 105 is started, which drives the threaded screw 106 fixed to the output shaft of the rotating motor 105 to rotate. When the threaded screw 106 rotates, the axial rotation is limited by the sliding cooperation between the U-shaped baffle 104 and the limiting round rod 103, thereby driving the U-shaped baffle 104 to slide to the right inside the portable case 1 (towards...). Figure 3Taking the direction shown as an example, when the U-shaped baffle 104 slides to the right inside the portable case 1, the lifting arm 108, which is hinged between the third hinge seat 107 and the fourth hinge seat 318, will lift relative to each other. This will cause the sliding holes 317 through the top of the lifting plate 303 to slide upward on the periphery of the guide posts 102 fixed at the bottom inside the portable case 1, until the lifting plate 303 slides out of the portable case 1. Then, the rotating motor 105 is turned off, and the subsequent 3D curved glass film application is performed. When it is necessary to... When applying film to 3D curved glass, place the 3D curved glass stably in the top center of the U-shaped mounting plate 315. Then, activate the electric rods 308 fixed to the top of the two U-shaped support plates 306, causing the telescopic ends of the two electric rods 308 to pass through the perforation 307 at the top of the support plate 305 below the U-shaped support plate 306, and simultaneously telescopically move within the perforation 307. During the telescopic movement of the two electric rods 308, the first hinge seat 310 and the second hinge seat 308 are activated. The hinge arm 311, which is hinged between the two hinge seats 312, presses down or pulls up, thereby providing a relative force to the positioning plate 313 from left to right. This ultimately causes the two opposing positioning plates 313 to move closer or further apart within the convex groove 316 until the protective pads 314 on opposite sides of the two positioning plates 313 come into contact with both sides of the 3D curved glass to be coated. At this point, the two electric rods 308 are closed, and the telescopic rod 407 fixed to the top of the lower pressure plate 401 is activated, driving the telescopic rod... The lower pressure plate 401, fixed at the bottom of 407, moves downward until the component fixed at the bottom of the lower pressure plate 401 is in contact with the film surface of the 3D curved glass to be coated. Then, the telescopic rod 407 is closed. This completes the positioning and fixing of 3D curved glass of different sizes to be coated, preventing it from shifting during the later coating process and avoiding any impact on the later coating process. During use, there is no need to frequently change the positioning structure according to the size of the 3D curved glass to be coated, which brings certain convenience to the later coating process.

[0059] The working principle of this invention is as follows:

[0060] Before applying the film, open the lid 101, which is hinged to the top of the carrying case 1. Then, start the rotating motor 105, causing the U-shaped baffle 104 to slide to the right inside the carrying case 1. When the U-shaped baffle 104 slides to the right inside the carrying case 1, the lifting arm 108, which is hinged between the third hinge seat 107 and the fourth hinge seat 318, will lift relative to each other, thereby driving the lifting plate 303 to slide upward inside the carrying case 1 until the lifting plate 303 slides out of the carrying case 1. Then, turn off the rotating motor 105 and proceed with the subsequent 3D curved glass film application. Before applying the 3D curved glass film, place the 3D curved glass to be filmed stably inside the positioning component 3 for positioning and fixing. During the positioning and fixing process, start the two... The electric rods 308 extend and retract within the perforation 307. When the extension and retraction ends of the two electric rods 308 extend and retract, they cause the hinge arms 311, which are hinged between the first hinge seat 310 and the second hinge seat 312, to press down or lift. This provides a relative force to the positioning plates 313, ultimately causing the two opposing positioning plates 313 to move closer or further apart within the convex groove 316. This continues until the protective pads 314 on opposite sides of the two positioning plates 313 contact the two sides of the 3D curved glass to be coated, at which point the electric rods 308 are closed. After positioning and fixing are complete, the telescopic rod 407 is simultaneously activated, causing the pressure plate 401 fixed at the bottom of the telescopic rod 407 to engage. The device moves downwards until the outer bottom of the U-shaped plate 402 is in contact with the film surface of the 3D curved glass to be coated. Then, the telescopic rod 407 is closed to complete the positioning and fixing of 3D curved glass of different sizes to be coated, preventing them from shifting during the subsequent coating process. After the above preparations are completed, the servo motor 406 is started, driving the bidirectional threaded rod 405 fixed to the output shaft of the servo motor 406 to rotate, so that the two coating parts 5 move away from each other inside the two guide grooves 403 respectively. When the coating parts 5 move away from each other inside the two guide grooves 403, in the initial state before they move away, both coating parts 5 are inside the U-shaped plate 402. At this time, the arc spring 5 connected and fixed between the rotating plate 504 and the U-shaped base plate 502... When the two film-applying components 5 are in a compressed state, as they gradually slide out from inside the U-shaped plate 402, the compressed arc spring 507 begins to reset, driving the rotating plate 504 to press down and rotate on the circumferential side of the rotating shaft 503. This continues until the bonding roller 506, which rotates and engages with the circumferential side of the positioning shaft 505, comes into contact with the film surface on the 3D curved glass to be coated. Then, the two film-applying components 5 continue to move away from each other. As the two film-applying components 5 continue to move away from each other, their bonding roller 506 comes into contact with the film surface on the 3D curved glass to be coated. Subsequently, the rolling action of the bonding roller 506 effectively coats the side curved surface of the 3D curved glass, improving the bonding effect between the film and the side curved surface of the 3D curved glass and preventing the film from lifting off the side curved surface.

The threaded screw (106) passes through one outer side of the portable case (1) and is rotatably engaged with the portable case (1).

6. A method for applying a film to 3D curved glass according to any one of claims 1-5, characterized in that: The following methods and steps are included: T1. Before applying the film, open the lid (101) that is hinged to the top of the portable case (1), and then start the rotating motor (105) so that the U-shaped baffle (104) slides to the right inside the portable case (1); T2. When the U-shaped baffle (104) slides to the right inside the portable case (1), the lifting arm (108) hinged between the third hinge seat (107) and the fourth hinge seat (318) will lift relative to each other, thereby driving the lifting plate (303) to slide upward inside the portable case (1) until the lifting plate (303) slides out of the portable case (1). Then, the rotating motor (105) is turned off, and the subsequent 3D curved glass film application is carried out. Before applying the film to T3 and 3D curved glass, the 3D curved glass to be filmed is placed stably inside the positioning component (3) for positioning and fixing. During the positioning and fixing process, the two electric rods (308) are started, so that the electric rods (308) can move in and out of the perforation (307). T4. When the telescopic ends of the two electric rods (308) extend and retract, they drive the hinge arm (311) that is hinged between the first hinge seat (310) and the second hinge seat (312) to press down or lift, thereby providing a left-right relative force to the positioning plate (313), and ultimately driving the two opposing positioning plates (313) to move closer or further apart in the convex groove (316) until the protective pads (314) on the opposite side of the two positioning plates (313) come into contact with the two sides of the 3D curved glass to be coated, and then the two electric rods (308) are closed. T5. After the positioning and fixing are completed, the telescopic rod (407) is started at the same time, which drives the lower pressure plate (401) fixed at the bottom of the telescopic rod (407) to move downward until the outer bottom of the U-shaped plate (402) is in contact with the film surface of the 3D curved glass to be filmed. Then the telescopic rod (407) is closed. This completes the positioning and fixing of 3D curved glass of different sizes to be filmed, and prevents it from shifting during the later filming process. T6. After the preparation work in T1 to T5 is completed, start the servo motor (406) and drive the bidirectional threaded rod (405) fixed to the output shaft of the servo motor (406) to rotate, so that the two film-applying parts (5) are separated from each other in the two guide grooves (403); T7. When the film-applying parts (5) are far apart from each other inside the two guide grooves (403), in the initial state before they are far apart, both film-applying parts (5) are inside the U-shaped plate (402). At this time, the arc spring (507) connected and fixed between the rotating plate (504) and the U-shaped base plate (502) is in a compressed state. T8. When the two film-applying parts (5) gradually slide out from inside the U-shaped plate (402), the compressed arc spring (507) begins to reset, driving the rotating plate (504) to press down and rotate on the circumferential side of the rotating shaft (503) until the bonding roller (506) that rotates and engages with the circumferential side of the positioning shaft (505) comes into contact with the film surface on the 3D curved glass to be coated. Then the two film-applying parts (5) continue to move away from each other. T9. When the two film-applying parts (5) continue to move away from each other, their bonding rollers (506) come into contact with the film surface on the 3D curved glass to be coated, and then the bonding rollers (506) roll in the later stage to effectively apply the film to the side curved surface of the 3D curved glass, thereby improving the bonding effect between the film and the side curved surface of the 3D curved glass and preventing the film from lifting off the side curved surface.
