Description

Technical Field

[0001] This invention relates to the field of 3D glass film technology, specifically to 3D glass film application equipment and methods. Background Technology

[0002] 2D glass is flat; no matter which point you choose on the glass, it should be on the same plane as other points on the glass. 2.5D glass has a flat area in the center of the glass, and then the edges are curved on the basis of the flat glass. 3D glass refers to a screen with a curved surface throughout.

[0003] Traditional window film application methods require first cleaning the glass surface to ensure it is free of adhesive, particles, and stains. After cleaning, water or adhesive is sprayed onto the glass surface. The window film is then applied to the glass surface, and its position is adjusted. Once the window film is fully aligned with the glass, any air bubbles and water between the film and the glass are scraped off.

[0004] A search revealed that Chinese patent CN221437243U discloses an automatic film-applying device for 3D curved glass. Although the device achieves pre-pressing of the film and curved glass through film transport and pre-pressing components, and then further presses the film in a vacuum environment using a lifting curved pressing plate, it can effectively avoid problems such as bubbles and creases, and the film application effect is good. However, the closing and sealing of the vacuum hood during vacuuming requires additional operation steps, which makes the operation complicated and prolongs the film application time. At the same time, the device has too many control components, requiring complex control commands to achieve the expected effect. This requires multiple control components to work, increasing the risk of equipment damage, reducing the lifespan of the equipment, and also requiring consideration of wiring and cost. Summary of the Invention

[0005] The purpose of this invention is to provide a 3D glass film application device and method.

One end of a track is slidably sleeved on the outer surface of the driving roller, and a driven roller is slidably sleeved on the other end of the track. A lead screw is fixedly connected on the central axis of the driven roller, and a lifting block is meshed on the outer surface of the lead screw. A fixing block is fixedly connected to the side wall of the lifting block, and one end of a third spring is fixedly connected to the bottom surface of the fixing block. A scraper is fixedly connected to the other end of the third spring. Vertical plates are fixedly connected to both the upper and lower sides of the lifting block. One end of a sliding frame is slidably sleeved on the outer surface of the vertical plate, and the other end of the sliding frame is fixedly connected to the side wall of the groove. A clamping frame is fixedly connected to the side wall of the lifting block.

[0008] As a further embodiment of the present invention: the second channel is arranged in a herringbone shape, and there are two of each of the sealed cavity, the second piston and the pin. The two sealed cavities, the two second pistons and the two pins are symmetrically arranged about the bisecting plane of the cover plate. The pin is arranged in a quadrangular prism shape and is fitted and sleeved with the rotation point of the cover plate.

[0009] As a further embodiment of the present invention: the central axis of the guide tube is separate from the central axis of the connecting frame, the connecting frame is fixedly connected to the side wall of the fitting box, the track extends into the groove, the driven roller is rotatably connected to the top surface of the groove, and the lifting block is slidably sleeved with the groove.

[0010] As a further embodiment of the present invention: the sliding frame is slidably connected to the side wall of the groove, the scraper is slidably sleeved with the top surface of the feed inlet, the side wall of the scraper is arc-shaped, and the clamping frame is slidably connected to the inner surface of the bonding box.

[0011] As a further embodiment of the present invention: both ends of the conveyor belt are rotatably sleeved with rollers, the bottom surface of the lead screw is fixedly connected with a main helical gear, the outer surface of the main helical gear is meshed with a secondary helical gear, a worm is fixedly connected on the central axis of the secondary helical gear, the outer surface of the worm is meshed with a worm wheel, and the worm wheel is fixedly sleeved with the rollers.

[0012] As a further embodiment of the present invention: the secondary helical gear is rotatably connected to the side wall of the groove, and the worm gear is rotatably connected to the bottom wall of the fitting box.

[0013] As a further aspect of the present invention: the worm gear drives the conveyor belt to rotate via a worm wheel and a rotating roller.

[0014] The 3D glass film application method, the specific operation steps of this glass film application method are as follows:

[0015] S1. Open the cover plate, apply the glass film to the bottom of the clamping frame and close the cover plate. At this time, start the air pump to draw out the air in the bonding box. The air is guided into the first channel through the output pipe, which indirectly pushes the second piston to engage with the cover plate and fix the cover plate. As the air pump continues to work, the high-pressure air in the collecting cavity fills the ring groove, which increases the air pressure between the sealing ring and the bottom of the ring groove, thereby pushing the sealing ring to rise and squeezing the cover plate, thus sealing the gap between the cover plate and the bonding box.

[0016] S2. Continuously remove the air from the lamination box and place the glass on the conveyor belt, allowing the glass to automatically enter the lamination box. At the same time, the scraper descends autonomously, making contact with the glass to clean its surface. After the glass has completely entered the lamination box, the scraper descends under the rebound of the third spring and seals the feed port, facilitating the subsequent vacuuming stop. Simultaneously, the lifting block drives the clamping frame to descend, allowing the glass film on the clamping frame to adhere to the glass surface. Finally, the vacuum state of the lamination box is released, allowing the glass film to adhere tightly to the glass under atmospheric pressure, completing the glass lamination process.

[0017] Compared with the prior art, the beneficial effects of the present invention, using the above technical solution, are as follows:

[0018] 1. This invention uses an air pump to extract air from the bonding box, allowing the air to enter the first channel through the output pipe. The first channel is connected to the collecting chamber, which in turn is connected to the second channel. This allows the air to further enter the second channel and, guided by the second channel, fill the sealed cavity. This increases the air pressure between the second piston and the sealed cavity, causing the second piston to push the pin out of the sealed cavity. The pin then engages with the cover plate, securing the cover plate. As the air pump continues to operate, the air pressure in the sealed cavity and the collecting chamber continues to rise until the air in the collecting cavity pushes the first piston to move horizontally. This causes the first piston to stretch the first spring and disengage from the collecting cavity, allowing the high-pressure air in the collecting cavity to fill the annular groove. This increases the air pressure between the sealing ring and the bottom of the annular groove, pushing the sealing ring upward. The sealing ring then presses against the cover plate, sealing the gap between the cover plate and the bonding box. This eliminates the need for additional steps in fixing and sealing the cover plate, allowing it to be completed automatically during the film application process. This simplifies operation and shortens the film application time.

[0019] 2. This invention uses high-pressure air in the annular groove to push the third piston downward, causing the third piston to compress the second spring and simultaneously open the third channel. The compressed air then flows back through the guide of the third channel to the output hole, which is connected to a conduit and a connecting frame. This allows the compressed air to rush into the connecting frame, causing the spiral fan blades within the frame to rotate. The spiral fan blades then drive the active roller to rotate, causing the track on the active roller to drive the driven roller to rotate. This causes the lead screw on the driven roller to drive the main helical gear to rotate, and the secondary helical gear, meshing with the main helical gear, drives the worm gear to rotate. The worm wheel on the worm gear then drives the rotating roller to rotate, causing the rotating roller to drive the conveyor belt to rotate. The glass is then placed on the conveyor belt, achieving autonomous glass movement. When the bonding box is completely vacuumed, the glass automatically stops moving, eliminating the need for other devices to position the glass. Furthermore, no additional drive components are required, and the kinetic energy generated during vacuuming can be recovered, reducing costs and achieving energy conservation and emission reduction.

[0020] 3. This invention uses the rotation of the lead screw to synchronously drive the lifting block to descend, causing the fixed block on the lifting block to compress the third spring and push the scraper down, making the scraper contact the glass. At the same time, the glass moves, allowing the scraper to clean the surface of the glass. After the glass is completely in the bonding box, the scraper can descend under the rebound of the third spring and seal the feed port, facilitating the subsequent stopping of vacuuming. In the above process, the equipment only controls the start and stop of the air pump, without the need for additional control components. The expected effect can be achieved with simple control commands, which not only reduces the risk of equipment damage and extends the life of the equipment and the duration of continuous operation, but also eliminates the need to consider wiring and costs.

[0032] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Example 1

[0034] Please see Figures 1-8 This invention provides a technical solution: a 3D glass lamination device and method, comprising a lamination box 1, a cover plate 2 hinged to the side wall of the lamination box 1, a feed inlet 3 on the side wall of the lamination box 1, a conveyor belt 4 rotatably sleeved on the inner bottom surface of the lamination box 1, an annular groove 11 on the top surface of the lamination box 1, a groove on the inner side wall of the lamination box 1, an output hole 6 penetrating through the side wall of the lamination box 1, a first channel 7 at one end on the inner surface of the output hole 6, a collecting cavity 8 at the other end of the first channel 7, the collecting cavity 8 communicating with the annular groove 11, and a second channel 9 at one end on the bottom surface of the collecting cavity 8, a sealed cavity 10 at the other end of the second channel 9, and the annular groove 11... A third channel 12 is provided on the bottom surface. The end of the third channel 12 is connected to the output hole 6. An air pump 13 is installed at one end of the output hole 6, and a conduit 15 is fixedly connected to the other end of the output hole 6. An output pipe 14 is fixedly connected between the air pump 13 and the first channel 7. A first piston 16 is slidably sleeved in the collecting cavity 8. A first spring 17 is fixedly connected between the first piston 16 and the side wall of the collecting cavity 8. A second piston 18 is slidably sleeved in the sealed cavity 10. A pin 19 is fixedly connected to the end face of the second piston 18. A third piston 20 is slidably sleeved in the third channel 12. A second spring 21 is fixedly connected between the third piston 20 and the third channel 12. A sealing ring 39 is slidably sleeved in the annular groove 11.

[0035] Please see Figure 2 , Figure 3 and Figure 7 The second channel 9 is arranged in a herringbone shape. There are two sealed cavities 10, two second pistons 18 and two pins 19. The two sealed cavities 10, two second pistons 18 and two pins 19 are symmetrically arranged about the bisecting plane of the cover plate 2. The pins 19 are arranged in a quadrangular prism shape and are fitted and sleeved with the rotation point of the cover plate 2.

[0036] Please see Figure 3 , Figure 4 and Figure 10 The central axis of the guide tube 15 is separate from the central axis of the connecting frame 22. The connecting frame 22 is fixed to the side wall of the fitting box 1. The track 25 extends into the groove. The driven roller 26 is rotatably connected to the top surface of the groove. The lifting block 28 is slidably connected to the groove.

[0037] Specifically, during the glass film application process, the cover plate 2 is opened, the glass film is applied to the bottom surface of the clamping frame 38, and the cover plate 2 is closed. At this time, the air pump 13 is started, causing the air pump 13 to draw out the air in the bonding box 1. The air is then guided into the first channel 7 through the output pipe 14. The first channel 7 is connected to the collecting chamber 8, and the collecting chamber 8 is connected to the second channel 9. This allows the air to further enter the second channel 9 and be guided into the sealed chamber 10. This increases the air pressure between the second piston 18 and the sealed chamber 10, causing the second piston 18 to push the pin 19 out of the sealed chamber 10. The pin 19 then engages with the cover plate 2, thus fixing the cover plate 2. The purpose is that, as the air pump 13 continues to work, the air pressure in the sealed cavity 10 and the collecting cavity 8 continues to rise until the air in the collecting cavity 8 pushes the first piston 16 to move horizontally. This causes the first piston 16 to stretch the first spring 17 and disengage from the collecting cavity 8, allowing the high-pressure air in the collecting cavity 8 to fill the annular groove 11. This increases the air pressure between the sealing ring 39 and the bottom surface of the annular groove 11, thereby pushing the sealing ring 39 to rise. This causes the sealing ring 39 to press against the cover plate 2, thus sealing the gap between the cover plate 2 and the bonding box 1. This allows the fixing and sealing of the cover plate 2 to be completed automatically during the film application process without additional operation steps, making the operation simple and shortening the film application time.

[0038] Example 2

[0039] Please see Figure 5 and Figure 10 The present invention provides a technical solution: a 3D glass film application device and method, wherein both ends of the conveyor belt 4 are rotatably sleeved with rollers 5, the bottom surface of the lead screw 27 is fixedly connected with a main helical gear 34, the outer surface of the main helical gear 34 is meshed with a secondary helical gear 35, a worm gear 36 is fixedly connected on the central axis of the secondary helical gear 35, the outer surface of the worm gear 36 is meshed with a worm wheel 37, and the worm wheel 37 is fixedly sleeved with the rollers 5.

[0040] Please see Figure 4 and Figure 10 The secondary helical gear 35 is rotatably connected to the side wall of the groove, and the worm gear 36 is rotatably connected to the bottom wall of the fitting box 1.

[0041] Please see Figure 10 The worm gear 36 drives the conveyor belt 4 to rotate via the worm wheel 37 and the rotating roller 5.

[0042] Specifically, during the continuous operation of the air pump 13, the air pressure in the annular groove 11 continuously rises until the high-pressure air in the annular groove 11 pushes the third piston 20 downward, causing the third piston 20 to compress the second spring 21 and simultaneously open the third channel 12. This allows the compressed air to flow back through the guide of the third channel 12 to the output hole 6, which is connected to the conduit 15, which in turn is connected to the connecting frame 22. This allows the compressed air to rush into the connecting frame 22, causing the spiral fan blade 23 inside the connecting frame 22 to rotate. Consequently, the spiral fan blade 23 drives the drive roller 24 to rotate, causing the track 2 on the drive roller 24 to rotate. 5 drives the driven roller 26 to rotate, which in turn causes the lead screw 27 on the driven roller 26 to drive the main helical gear 34 to rotate. This causes the secondary helical gear 35, which meshes with the main helical gear 34, to drive the worm gear 36 to rotate. This causes the worm wheel 37 on the worm gear 36 to drive the rotating roller 5 to rotate, which in turn causes the rotating roller 5 to drive the conveyor belt 4 to rotate. At this time, the glass is placed on the conveyor belt 4, achieving the purpose of autonomously moving the glass. When the bonding box 1 is completely vacuumed, the glass automatically stops moving. No other device is needed to position the glass, and no additional drive components are required. The kinetic energy during vacuuming can also be recovered, reducing costs and saving energy and reducing emissions.

[0043] Example 3

[0044] Please see Figure 5 , Figure 9 and Figure 10 This invention provides a technical solution: a 3D glass film application device and method. The end of the conduit 15 is connected to a connecting frame 22. A spiral fan blade 23 is rotatably connected inside the connecting frame 22. The bottom end of the spiral fan blade 23 passes through the connecting frame 22, and a driving roller 24 is fixedly connected to the bottom surface of the spiral fan blade 23. One end of a track 25 is slidably sleeved on the outer surface of the driving roller 24. A driven roller 26 is slidably sleeved on the other end of the track 25. A wire is fixedly connected to the central axis of the driven roller 26. The outer surface of the rod 27 is fitted with a lifting block 28. A fixing block 31 is fixedly connected to the side wall of the lifting block 28. One end of a third spring 32 is fixedly connected to the bottom surface of the fixing block 31. A scraper 33 is fixedly connected to the other end of the third spring 32. Vertical plates 29 are fixedly connected to both the upper and lower sides of the lifting block 28. One end of a sliding frame 30 is slidably fitted to the outer surface of the vertical plate 29. The other end of the sliding frame 30 is fixedly connected to the side wall of the groove. A clamping frame 38 is fixedly connected to the side wall of the lifting block 28.

[0045] Please see Figures 3-5 The sliding frame 30 is slidably connected to the side wall of the groove, the scraper 33 is slidably sleeved with the top surface of the feed port 3, the side wall of the scraper 33 is arc-shaped, and the clamping frame 38 is slidably connected to the inner surface of the bonding box 1.

[0046] Specifically, during the glass conveying process, the rotation of the lead screw 27 synchronously drives the lifting block 28 to descend, causing the fixed block 31 on the lifting block 28 to compress the third spring 32 and push the scraper 33 to descend, so that the scraper 33 contacts the glass. At the same time, the glass moves, allowing the scraper 33 to clean the surface of the glass. After the glass has completely entered the bonding box 1, the scraper 33 can descend under the rebound of the third spring 32 and seal the feed port 3, which facilitates the subsequent vacuuming to stop. In the above process, the equipment only controls the opening and closing of the air pump 13, without the need for additional control components to participate in the work. The expected effect can be achieved with simple control commands, which not only reduces the risk of equipment damage and extends the life of the equipment and the duration of continuous operation, but also eliminates the need to consider wiring and cost.

[0047] The working principle and usage process of this invention are as follows: When glass film needs to be applied, open the cover plate 2, apply the glass film to the bottom surface of the clamping frame 38, and close the cover plate 2. At this time, start the air pump 13 to draw out the air from the bonding box 1. The air is then guided into the first channel 7 through the output pipe 14. The first channel 7 is connected to the collecting chamber 8, and the collecting chamber 8 is connected to the second channel 9. This allows the air to further enter the second channel 9 and be guided into the sealed cavity 10. This increases the air pressure between the second piston 18 and the sealed cavity 10, causing the second piston 18 to push the pin 19 out of the sealed cavity 10. This allows the pin 19 to engage with the cover plate 2, achieving the desired effect. The purpose of fixing the cover plate 2 is that, as the air pump 13 continues to work, the air pressure in the sealed cavity 10 and the collecting cavity 8 continues to rise until the air in the collecting cavity 8 pushes the first piston 16 to move horizontally. This causes the first piston 16 to stretch the first spring 17 and disengage from the collecting cavity 8, allowing the high-pressure air in the collecting cavity 8 to fill the annular groove 11. This increases the air pressure between the sealing ring 39 and the bottom surface of the annular groove 11, thereby pushing the sealing ring 39 to rise. This causes the sealing ring 39 to squeeze the cover plate 2, thus sealing the gap between the cover plate 2 and the bonding box 1. This allows the fixing and sealing of the cover plate 2 to be completed automatically during the film application process without additional operation steps, making the operation simple and shortening the film application time.

[0048] As the air pump 13 continues to operate, the air pressure in the annular groove 11 continues to rise until the high-pressure air in the annular groove 11 pushes the third piston 20 down, causing the third piston 20 to compress the second spring 21 and simultaneously open the third channel 12. This allows the compressed air to flow back through the guide of the third channel 12 to the output hole 6, which is connected to the conduit 15, which in turn is connected to the connecting frame 22. This allows the compressed air to rush into the connecting frame 22, causing the spiral fan blade 23 inside the connecting frame 22 to rotate. Consequently, the spiral fan blade 23 drives the drive roller 24 to rotate, which in turn causes the track 25 on the drive roller 24 to rotate. The driven roller 26 rotates, which in turn causes the lead screw 27 on the driven roller 26 to drive the main helical gear 34 to rotate. This causes the secondary helical gear 35, which meshes with the main helical gear 34, to drive the worm gear 36 to rotate. This causes the worm wheel 37 on the worm gear 36 to drive the rotating roller 5 to rotate, which in turn causes the rotating roller 5 to drive the conveyor belt 4 to rotate. At this time, the glass is placed on the conveyor belt 4, achieving the purpose of autonomously driving the glass to move. When the bonding box 1 is completely vacuumed, the glass automatically stops moving. No other device is needed to position the glass, and no additional drive components are required. The kinetic energy during vacuuming can also be recovered, reducing costs and saving energy and reducing emissions.

[0049] During the above process, the rotation of the lead screw 27 can synchronously drive the lifting block 28 to descend, so that the fixed block 31 on the lifting block 28 compresses the third spring 32 and pushes the scraper 33 to descend, so that the scraper 33 contacts the glass. At the same time, the glass moves, so that the scraper 33 cleans the surface of the glass. After the glass has completely entered the bonding box 1, the scraper 33 can descend under the rebound of the third spring 32 and seal the feed port 3, which facilitates the subsequent vacuuming to stop. During the above process, the equipment only controls the start and stop of the air pump 13, without the need for additional control components to participate in the work. The expected effect can be achieved with simple control commands, which not only reduces the risk of equipment damage and extends the life of the equipment and the duration of continuous operation, but also eliminates the need to consider wiring and cost to complete the operation.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.

8. A 3D glass film application method using the 3D glass film application equipment according to any one of claims 1-7, characterized in that: The specific steps for applying this glass film are as follows: S1. Open the cover plate (2), then apply the glass film to the bottom surface of the clamping frame (38) and close the cover plate (2). At this time, start the air pump (13) to draw out the air in the bonding box (1) and let the air enter the first channel (7) through the guide of the output pipe (14). This indirectly causes the second piston (18) to push the pin (19) to engage with the cover plate (2) and fix the cover plate (2). As the air pump (13) continues to work, the high-pressure air in the collecting chamber (8) fills the ring groove (11), which increases the air pressure between the sealing ring (39) and the bottom surface of the ring groove (11), thereby pushing the sealing ring (39) to rise and causing the sealing ring (39) to squeeze the cover plate (2), thus sealing the gap between the cover plate (2) and the bonding box (1). S2. Continuously remove the air from the bonding box (1) and place the glass on the conveyor belt (4) so ​​that the glass automatically enters the bonding box (1). At the same time, the scraper (33) descends autonomously, so that the scraper (33) contacts the glass and cleans the surface of the glass. After the glass has completely entered the bonding box (1), the scraper (33) can descend under the rebound of the third spring (32) and seal the feed port (3) to facilitate the subsequent vacuuming stop. At the same time, the lifting block (28) drives the clamping frame (38) to descend, so that the glass film on the clamping frame (38) is applied to the glass surface. Finally, the vacuum state of the bonding box (1) is released, so that the glass film is tightly attached to the glass under the action of atmospheric pressure, and the glass film is completed.
