[0001] This utility model relates to the technical field of display screen lamination, specifically to a lamination device for a head-up display screen. Background Technology
[0002] Display screen lamination is a key technology that involves bonding optical thin films to the surface of a display screen using hot or cold pressing processes. It is primarily used to improve display quality and protect the screen. Its core processes include cleaning, alignment calibration, temperature / pressure control, and curing, all of which must be performed in a cleanroom environment.
[0003] According to Chinese Patent No. CN221251883U, a laminating device for display screen production includes a frame, which also includes two rotating shafts symmetrically distributed and rotatably connected to the inner sidewall of the frame. A conveyor belt is fitted onto the outer surface of both rotating shafts. A drive motor is fixed to the inner sidewall of the frame. A sprocket is provided between the output shaft of the drive motor and one of the rotating shafts. The two sprockets are connected by a chain. A base plate is fixed to the bottom sidewall of the frame, and a frame is fixed to the top sidewall of the base plate. A laminating assembly is disposed inside the frame.
[0004] In the above solution, a film-pressing assembly is used to cover the display screen, which still has the following disadvantages: the film may wrinkle during the transmission process before covering the display screen. Utility Model Content
[0005] The purpose of this invention is to provide a film pressing device for a head-up display screen to solve the problem of wrinkles that may occur during the transmission of the film before it covers the display screen.
[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a pressing device for a head-up display screen, comprising two fixed plates, both fixed plates being fixed to the top surface of a conveying trough, a conveying roller being rotatably arranged between the two fixed plates, a lifting plate being arranged above the conveying trough, two sliding grooves being formed on the top surface of the fixed plates, sliding rods being fixed at the four corners of the bottom surface of the lifting plate, the sliding rods being slidably inserted into the sliding grooves, and a flat plate being fixed to the bottom surface of the lifting plate, the bottom surface of the flat plate having a semi-cylindrical structure.
[0007] Preferably, the conveyor belt is provided inside the conveying trough, a mounting plate is fixed on the top surface of the conveying trough, a pressing plate is slidably arranged inside the mounting plate, a plurality of cylinders are provided on the top surface of the mounting plate, the bottom end of the cylinder extension rod is fixed to the top surface of the pressing plate, and a plurality of mounting plates are fixed on the bottom surface of the pressing plate, wherein two mounting plates form a group, and a pressing roller is rotatably arranged between the two mounting plates in each group.
[0008] Preferably, a limiting post is fixed to the surface of the sliding rod, and a limiting opening is formed on the inner wall of the sliding groove, with the limiting post and the limiting opening being slidably disposed.
[0009] Preferably, a positioning post is fixed on the top surface of the lifting plate, and a counterweight ring is inserted into the positioning post.
[0010] Preferably, a stabilizing rod is fixed to the top surface of each of the four corners of the pressing plate, and a plurality of fitting holes are opened on the top surface of the mounting plate, wherein the fitting holes are slidably inserted with the stabilizing rods.
[0011] Preferably, a support plate is fixed inside the conveying trough.
[0012] Compared with existing technologies, the lamination device for a head-up display screen that adopts the above technical solution has the following beneficial effects:
[0013] 1. By using the lifting plate and the gravity of the entire plate, combined with the semi-cylindrical structure of the bottom surface of the entire plate, the pressed film is flattened and smoothed, and then the head-up display screen is pressed, which reduces the probability of wrinkles in the finished product.
[0014] 2. During the lifting process, the lifting plate will drive the sliding rod to move synchronously inside the sliding groove, which in turn drives the limiting post to slide inside the limiting port. By using the length limitation of the limiting port, the sliding rod is prevented from disengaging from the inside of the sliding groove. In addition, the staff can also put different numbers of counterweight rings on the positioning post according to their needs, so as to adjust the magnitude of the downward force applied by the whole plate to the film.
[0015] Third, the support plate is located inside the conveyor belt. When the pressing roller applies downward pressure to the display screen and the film, the support plate will provide upward support to the display screen and the film. When the pressing plate moves up and down inside the mounting plate, the stabilizing rod will move up and down synchronously inside the sleeve hole, thereby increasing the stability of the pressing plate when it moves up and down.

[0022] like Figures 1-4 As shown, a pressing device for a head-up display screen includes two fixed plates 1, both fixed plates 1 are fixed to the top surface of a conveying trough 2, a conveying roller 7 is rotatably arranged between the two fixed plates 1, a lifting plate 3 is arranged above the conveying trough 2, two sliding grooves 4 are opened on the top surface of the fixed plates 1, sliding rods 5 are fixed at the four corners of the bottom surface of the lifting plate 3 respectively, the sliding rods 5 are slidably inserted into the sliding grooves 4, a flat plate 6 is fixed on the bottom surface of the lifting plate 3, the bottom surface of the flat plate 6 has a semi-cylindrical structure, a conveyor belt 8 is arranged inside the conveying trough 2, a mounting folding plate 9 is fixed on the top surface of the conveying trough 2, a pressing plate 10 is slidably arranged inside the mounting folding plate 9, a plurality of cylinders 11 are arranged on the top surface of the inner surface of the mounting folding plate 9, the bottom end of the telescopic rod of the cylinder 11 is fixed to the top surface of the pressing plate 10, a plurality of mounting plates 12 are fixed on the bottom surface of the pressing plate 10, two mounting plates 12 form a group, and a pressing roller 13 is rotatably arranged between each group of two mounting plates 12.
[0023] During use, the head-up display screen moves to the inside of the mounting plate 9 under the drive of the conveyor belt 8. The film passes over the top of the conveyor roller 7 and enters the inside of the mounting plate 9. When the film passes through the conveyor roller 7, it is between the conveyor roller 7 and the straightening plate 6. The straightening plate 6 applies downward pressure to the film during the conveying process and uses its semi-cylindrical structure at the bottom to flatten and straighten the film. The head-up display screen and the film inside the mounting plate 9 are located below the pressing plate 10. The pressing plate 10 moves downward under the push of the telescopic rod of the cylinder 11 and drives the pressing roller 13 to press on the head-up display screen and the film. Multiple pressing rollers 13 are used to press the head-up display screen and the film multiple times to complete the pressing of the head-up display screen.
[0024] By using the weight of the lifting plate 3 and the flat plate 6, combined with the semi-cylindrical structure on the bottom of the flat plate 6, the pressed film is flattened and smoothed, and then the head-up display screen is pressed, reducing the probability of wrinkles in the finished product.
[0025] like Figure 3As shown, a limit post 14 is fixed on the surface of the sliding rod 5, and a limit opening 15 is opened on the inner wall of the sliding groove 4. The limit post 14 and the limit opening 15 are slidably arranged. A positioning post 16 is fixed on the top surface of the lifting plate 3, and a counterweight ring 17 is inserted on the positioning post 16.
[0026] During use, the lifting plate 3 will drive the sliding rod 5 to move synchronously inside the sliding groove 4 during the lifting process, thereby driving the limiting post 14 to slide inside the limiting port 15. By using the length limitation of the limiting port 15, the sliding rod 5 is prevented from disengaging from the inside of the sliding groove 4. In addition, the staff can also put different numbers of counterweight rings 17 on the positioning post 16 as needed, so as to adjust the magnitude of the downward force applied by the plate 6 to the film.
[0027] like Figure 2 and Figure 4 As shown, stabilizing rods 19 are fixed to the top surfaces of the four corners of the pressing plate 10, and several fitting holes 18 are opened on the top surface of the mounting plate 9.
