Description

Technical Field

[0001] This invention belongs to the field of automotive curved screen production technology, specifically an automotive curved screen glass bonding device and bonding method. Background Technology

[0002] In-vehicle curved screens are an important part of modern car interior design. During the manufacturing process, the display panel is tightly bonded to the glass cover to form a sturdy and durable composite panel. This not only protects the display panel from physical damage but also provides a good tactile and visual experience.

[0003] A search revealed a patent, CN216942232U, for example, a curved glass vacuum bonding device. This device includes an upper cavity and a lower cavity that form a vacuum chamber when closed. An elastic contouring fixture is installed in the upper cavity, and a contouring platform is installed in the lower cavity. A movable chuck for supporting a flat panel display screen is installed between the elastic contouring fixture and the contouring platform. A curved glass cover plate is vacuum-adsorbed onto the lower end face of the elastic contouring fixture or the upper end face of the contouring platform. By changing the structure of the contouring fixture, the curved glass cover plate and the flat panel display screen are bonded within the vacuum chamber, effectively preventing the generation of air bubbles. Furthermore, by combining hard-to-hard and soft-to-hard bonding processes, the device avoids breakage of the glass cover plate during bonding, thus improving the bonding success rate.

[0004] During manufacturing and transportation, display panels and glass covers may become contaminated with dust, particles, and other foreign objects. If these foreign objects are not removed, they will form gaps or air bubbles during the bonding process, affecting the tightness of the bonding and ultimately impacting the quality and performance of the product. Summary of the Invention

[0005] The purpose of this invention is to provide a vehicle-mounted curved screen glass bonding device and bonding method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vehicle-mounted curved screen glass bonding device, comprising a device body, a first curved surface fixedly mounted on the top of the device body, a cleaning component disposed on the top of the first curved surface, a second curved surface disposed above the first curved surface, a lifting drive component mounted on the top of the second curved surface, cylinders disposed on both sides of the first curved surface, positioning claws disposed on the top of the two cylinders, and a display screen disposed on the top of the positioning claws;

[0007] The cleaning assembly includes two cleaning sleeves disposed at the top of the first curved surface. Each cleaning sleeve has a cleaning roller embedded inside. One end of each cleaning roller is fixedly mounted with a first rotating shaft. The ends of the two first rotating shafts away from the cleaning rollers are respectively rotatably connected to a moving block and a connecting block. A connecting rod is fixedly mounted at the top of the connecting block. The connecting rod is embedded inside the moving block. A spring is sleeved on the outer wall of the connecting rod. A threaded rod is threadedly connected inside the moving block. The threaded rod is rotatably mounted inside the main body of the device. A motor is mounted at one end of the threaded rod.

[0008] As a further technical solution of the present invention, gears are fixedly installed on the outer walls of the two first rotating shafts, and rack plates are meshed on one side of each of the two gears.

[0009] As a further technical solution of the present invention, one of the rack plates is fixedly installed inside the device body, and the other rack plate is slidably installed inside the device body.

[0010] As a further technical solution of the present invention, the cleaning roller is provided with through holes evenly distributed inside, and a baffle is provided at the top of the through hole. Both ends of the baffle are fixedly connected to a second rotating shaft, which is embedded inside the cleaning roller.

[0011] As a further technical solution of the present invention, the second rotating shaft is rotatably connected to the cleaning roller.

[0012] As a further technical solution of the present invention, a liquid filling pipe is fixedly connected to one side of the cleaning roller, and a liquid filling plug is embedded in the inner wall of the liquid filling pipe.

[0013] As a further technical solution of the present invention, a movable plate is provided on one side of the cleaning roller, a tension spring is installed inside the movable plate, a slider is provided at the bottom end of the tension spring, a pressure plate is installed at the bottom end of the slider, and the pressure plate is provided on one side of the cleaning sleeve.

[0014] As a further technical solution of the present invention, the pressure plate is rotatably connected to the slider.

[0015] As a further technical solution of the present invention, a connecting shaft is rotatably connected to one side of the moving plate, and the connecting shaft is slidably installed inside the cleaning roller.

[0016] A testing method for a vehicle-mounted curved screen glass bonding device includes the following steps:

[0017] S1: When bonding the curved screen glass in the vehicle, first place the display screen on the positioning claw, then place the curved glass cover plate on the top of the first curved surface, and then control the motor to start. The start of the motor drives the rotation of the threaded rod, the rotation of the threaded rod drives the movement of the moving block, the movement of the moving block drives the movement of the connecting rod, and the movement of the connecting rod drives the movement of the connecting block, so that the two first rotating shafts move synchronously. The movement of the first rotating shafts drives the movement of the cleaning roller, and the movement of the cleaning roller drives the movement of the cleaning sleeve, so that the two cleaning sleeves wipe and clean the display screen and the surface of the curved glass cover plate at the top of the first curved surface respectively.

[0018] S2: When the cleaning sleeve moves, the elastic potential energy of the spring keeps the cleaning sleeve in contact with the surface of the first curved surface for cleaning.

[0019] S3: When the two first rotating shafts move, the gear moves and meshes with the rack plate to rotate. The rotation of the gear drives the rotation of the first rotating shaft, and the rotation of the first rotating shaft drives the rotation of the cleaning roller, thereby causing the cleaning sleeve to rotate and clean it when it moves.

[0020] S4: After cleaning, the positioning claws are moved down by the cylinder so that the display screen covers the surface of the curved glass cover. Finally, the lifting drive is controlled to press down the second curved surface so that the display screen is attached to the curved glass cover at the top of the first curved surface and held for a period of time to complete the attachment.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. This invention, through the setting of the cleaning component, when bonding the curved screen glass of an automotive display, first places the display screen on the top of the positioning claw, then places the curved glass cover plate on the top of the first curved surface, and then controls the motor to start. The start of the motor drives the rotation of the threaded rod, the rotation of the threaded rod drives the movement of the moving block, the movement of the moving block drives the movement of the connecting rod, and the movement of the connecting rod drives the movement of the connecting block, thereby causing the two first rotating shafts to move synchronously. The movement of the first rotating shafts drives the movement of the cleaning roller, and the movement of the cleaning roller drives the movement of the cleaning sleeve, so that the two cleaning sleeves wipe and clean the bottom end of the display screen and the top end of the curved glass cover plate of the first curved surface respectively, to remove dust, particles and other foreign objects that have been contaminated during manufacturing and transportation, thereby improving the bonding quality.

[0023] 2. The present invention, through the rotation of the cleaning sleeves, causes the gear to rotate when the two cleaning sleeves move and mesh with the rack plate. The rotation of the gear drives the rotation of the first rotating shaft, which in turn drives the rotation of the cleaning roller. This causes the cleaning sleeves to rotate when they move. When in contact with the surface of the display screen or glass cover, the continuous rotational motion reduces direct friction with the surface, thereby reducing the risk of scratches and wear, and improving the cleaning effect.

[0024] 3. By setting through holes, the present invention allows the cleaning roller to rotate. As the second rotating shaft is rotatably connected to the cleaning roller, the baffle is located at the bottom of the cleaning roller due to its own gravity. The cleaning roller rotates, the through holes and the baffle are intersected, and the cleaning liquid is discharged. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1 to 8 As shown in the embodiment of the present invention, a vehicle-mounted curved screen glass bonding device includes a device body 1. A first curved surface 2 is fixedly installed on the top of the device body 1. A cleaning component is provided on the top of the first curved surface 2. A second curved surface 3 is provided above the first curved surface 2. A lifting drive component 4 is installed on the top of the second curved surface 3. Cylinders 7 are provided on both sides of the first curved surface 2. Positioning claws 6 are installed on the top of both cylinders 7. A display screen 5 is provided on the top of the positioning claws 6.

[0036] The cleaning component includes two cleaning sleeves 8 located at the top of the first curved surface 2. Each cleaning sleeve 8 has a cleaning roller 9 embedded inside it. One end of each cleaning roller 9 is fixedly mounted with a first rotating shaft 10. The ends of the two first rotating shafts 10 away from the cleaning rollers 9 are respectively rotatably connected to a moving block 11 and a connecting block 14. A connecting rod 15 is fixedly mounted at the top of the connecting block 14. The connecting rod 15 is embedded inside the moving block 11. A spring 16 is sleeved on the outer wall of the connecting rod 15. A threaded rod 12 is threadedly connected inside the moving block 11. The threaded rod 12 is rotatably mounted inside the main body 1 of the device. A motor 13 is mounted at one end of the threaded rod 12.

[0037] When bonding the curved screen glass of the vehicle, the display screen 5 is first placed on the top of the positioning claw 6, and then the curved glass cover plate is placed on the top of the first curved surface 2. Then, the motor 13 is started. The start of the motor 13 drives the rotation of the threaded rod 12. The rotation of the threaded rod 12 drives the movement of the moving block 11. The movement of the moving block 11 drives the movement of the connecting rod 15. The movement of the connecting rod 15 drives the movement of the connecting block 14, so that the two first rotating shafts 10 move synchronously. The movement of the first rotating shafts 10 drives the movement of the cleaning roller 9. The movement of the cleaning roller 9 drives the movement of the cleaning sleeve 8, so that the two cleaning sleeves 8 wipe and clean the bottom of the display screen 5 and the curved glass cover plate at the top of the first curved surface 2 respectively, so as to remove dust, particles and other foreign objects that have been contaminated during manufacturing and transportation, thereby improving the bonding quality.

[0038] When the cleaning sleeve 8 moves, the elastic potential energy of the spring 16 causes the connecting block 14 to always have a downward tendency, so that the cleaning sleeve 8 fits against the surface of the curved glass cover plate at the top of the first curved surface 2 and cleans it to ensure the degree of cleaning of the curved surface.

[0039] The existing patent CN216942232U discloses a curved glass vacuum bonding device. This patent discloses the device body 1, first curved surface 2, second curved surface 3, lifting drive component 4, display screen 5, positioning claw 6 and cylinder 7 proposed in this application. The technical means are not described in detail here.

[0040] like Figure 3 and Figure 5 As shown, gears 17 are fixedly installed on the outer walls of the two first rotating shafts 10, and rack plates 18 are meshed on one side of each gear 17.

[0041] As the two cleaning sleeves 8 move, the gear 17 moves and meshes with the rack plate 18, causing it to rotate. The rotation of the gear 17 drives the rotation of the first rotating shaft 10, which in turn drives the rotation of the cleaning roller 9. This causes the cleaning sleeves 8 to rotate as they move. When they come into contact with the surface of the display screen 5 or the glass cover, the continuous rotational motion reduces direct friction with the surface, thereby reducing the risk of scratches and wear and improving the cleaning effect.

[0042] like Figure 3 and Figure 5 As shown, one rack plate 18 is fixedly installed inside the device body 1, and the other rack plate 18 is slidably installed inside the device body 1.

[0043] The rack plate 18 on one side of the movable block 11 is fixedly installed inside the device body 1, and the rack plate 18 on one side of the connecting block 14 is slidably installed inside the device body 1, and the connecting block 14 and the rack plate 18 are slidably connected.

[0044] When the cleaning sleeve 8 on one side of the connecting block 14 moves up and down due to the curvature of the top of the first curved surface 2, the connecting block 14 moves up and down inside the main body 1 of the device. The connecting block 14 drives the rack plate 18 to move up and down, so that the rack plate 18 always maintains a meshing state with the gear 17 to ensure the stability of the connection.

[0045] like Figure 7 and Figure 8 As shown, the cleaning roller 9 has through holes 19 evenly distributed inside. A baffle 20 is provided at the top of the through hole 19. A second rotating shaft 21 is fixedly connected to both ends of the baffle 20. The second rotating shaft 21 is embedded inside the cleaning roller 9.

[0046] The cleaning roller 9 is filled with cleaning fluid;

[0047] The cleaning sleeve 8 is made of a material with a certain degree of water absorption, and cleans the surface of the curved glass cover and the display screen 5 by absorbing the cleaning liquid;

[0048] When the cleaning roller 9 rotates, the cleaning liquid inside the cleaning roller 9 is discharged from the through hole 19 and absorbed by the cleaning sleeve 8, further improving the cleaning effect.

[0049] like Figure 7 and Figure 8 As shown, the second rotating shaft 21 is rotatably connected to the cleaning roller 9.

[0050] During the rotation of the cleaning roller 9, the second rotating shaft 21 is rotatably connected to the cleaning roller 9. Due to the gravity of the baffle 20 itself, the baffle 20 is located at the bottom of the cleaning roller 9. The cleaning roller 9 rotates, and the through hole 19 and the baffle 20 are intersected, so the cleaning liquid is discharged.

[0051] like Figure 7 and Figure 8 As shown, a liquid filling pipe 22 is fixedly connected to one side of the cleaning roller 9, and a liquid filling plug 23 is embedded in the inner wall of the liquid filling pipe 22.

[0052] Cleaning fluid is added into the filling tube 22 by removing the filling plug 23.

[0053] like Figure 7 As shown, a movable plate 24 is provided on one side of the cleaning roller 9. A tension spring 26 is installed inside the movable plate 24. A slider 25 is provided at the bottom end of the tension spring 26. A pressure plate 27 is installed at the bottom end of the slider 25. The pressure plate 27 is located on one side of the cleaning sleeve 8.

[0054] The two ends of the tension spring 26 are fixedly connected to the inner wall of the movable plate 24 and the slider 25, respectively;

[0055] During operation, the elastic potential energy of the tension spring 26 causes the pressure plate 27 to press the cleaning sleeve 8 tightly, ensuring that the cleaning sleeve 8 is stably installed inside the cleaning roller 9.

[0056] like Figure 7 As shown, the pressure plate 27 is rotatably connected to the slider 25.

[0057] like Figure 7 As shown, a connecting shaft 28 is rotatably connected to one side of the movable plate 24, and the connecting shaft 28 is slidably installed inside the cleaning roller 9.

[0058] When it is necessary to replace the cleaning sleeve 8, first move the pressure plate 27 to one side of the cleaning sleeve 8, then rotate the pressure plate 27 to make the pressure plate 27 and the cleaning sleeve 8 separate, then rotate the moving plate 24 to pull the cleaning sleeve 8 out from one side for replacement.

[0059] A testing method for a vehicle-mounted curved screen glass bonding device includes the following steps:

[0060] S1: When bonding the curved screen glass of the vehicle, first place the display screen 5 on the positioning claw 6, then place the curved glass cover plate on the top of the first curved surface 2, and then control the motor 13 to start. The start of the motor 13 drives the rotation of the threaded rod 12, the rotation of the threaded rod 12 drives the movement of the moving block 11, the movement of the moving block 11 drives the movement of the connecting rod 15, and the movement of the connecting rod 15 drives the movement of the connecting block 14, so that the two first rotating shafts 10 move synchronously. The movement of the first rotating shafts 10 drives the movement of the cleaning roller 9, and the movement of the cleaning roller 9 drives the movement of the cleaning sleeve 8, so that the two cleaning sleeves 8 wipe and clean the surface of the display screen 5 and the curved glass cover plate at the top of the first curved surface 2 respectively.

[0061] S2: When the cleaning sleeve 8 moves, the elastic potential energy of the spring 16 keeps the cleaning sleeve 8 in contact with the surface of the first curved surface 2 for cleaning.

[0062] S3: When the two first rotating shafts 10 move, the gear 17 moves and meshes with the rack plate 18 to rotate. The rotation of the gear 17 drives the rotation of the first rotating shaft 10, and the rotation of the first rotating shaft 10 drives the rotation of the cleaning roller 9, thereby causing the cleaning sleeve 8 to rotate and clean it when it moves.

[0063] S4: After cleaning, the cylinder 7 drives the positioning claw 6 to move down, so that the display screen 5 covers the surface of the curved glass cover. Finally, the lifting drive 4 is controlled to push down the second curved surface 3, so that the display screen 5 is attached to the curved glass cover at the top of the first curved surface 2 and held for a period of time to complete the attachment.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
