[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0021] like Figures 1 to 3 As shown, this utility model provides an automatic flexible film bonding device, including a conveyor line 1 extending along the Y direction, which conveys a fixture 11 carrying a PCB board along the Y direction. A fixture transfer line extends along the Y direction, while the conveyor line and fixture transfer line are spaced apart along the X direction. The fixture transfer line sequentially includes a loading station, a film application station 10, a unloading station, and a PCB visual positioning station 20 along the Y direction, with the X direction perpendicular to the Y direction. The fixture transfer line includes a fixture transfer mechanism 2, which carries a fixture 11 that reciprocates along the Y direction between the loading station, film application station 10, unloading station, and PCB visual positioning station 20. A support frame is positioned above the conveyor line 1 and the fixture transfer line along the X direction. A first handling mechanism 5 and a third handling mechanism 9 are respectively positioned on both sides of the support frame along the Y direction. A second handling mechanism 8 is positioned on the side of the fixture transfer line away from the conveyor line. The first transport mechanism 5 transports the fixture 11 from the conveyor line 1 to the loading station and places it on the fixture transfer mechanism 2. The third transport mechanism 9 moves the fixture 11 from the fixture transfer mechanism 2 back to the conveyor line 1 at the unloading station. The second transport mechanism 8 picks up the flexible film, transports it to the film application station 10, and applies it to the PCB board.
[0022] The above scheme involves placing the PCB board to be laminated on the surface of conveyor line 1, which then transports the PCB board. The first transport mechanism 5 moves the PCB board to the fixture transfer mechanism 2, which then transfers the PCB board to the PCB vision positioning station 20. During this process, the second transport mechanism 8 picks up the flexible film and moves it above the lamination station 10. The fixture transfer mechanism 2 moves the PCB board below the lamination station 10 and rolls the flexible film onto the PCB board. After lamination, the fixture transfer mechanism 2 carries the PCB board to the unloading station, below the third transport mechanism 9. The third transport mechanism 9 removes the PCB board from the fixture transfer mechanism 2 and transfers it to conveyor line 1, which then transports the PCB board out, completing the unloading process. The cooperation of the conveyor line and the fixture transfer line achieves automated lamination. The lamination station and the PCB vision positioning station on the fixture transfer line enable pre-lamination film and PCB board positioning and lamination photography. The flexible film application mechanism is rationally laid out and occupies little space, consisting of a conveyor line, a support frame set above the conveyor line and fixture transfer line along the X direction, and a first and a third transport mechanism set on both sides of the support frame along the Y direction. The first transport mechanism transports the PCB board for loading, and the third transport mechanism transports the PCB board after film application for unloading.
[0023] like Figure 1 , Figure 2 As shown, a first CCD camera group 3 is installed at the film application station 10; a second CCD camera group 4 is installed at the PCB vision positioning station 20.
[0024] Using the above scheme: the second CCD camera group 4 at the PCB visual positioning station 20 performs visual positioning of the PCB board; the first CCD camera group 3 performs positional visual positioning of the flexible film, thereby achieving precise adhesion of the film to the PCB board.
[0025] like Figure 1 , Figure 2 As shown, a scanner 12 and an anti-static component 13 are sequentially arranged along the Y direction on the conveyor line 1, with the anti-static component 13 positioned between the scanner 12 and the first conveying mechanism 5. A PCB cleaning component 14 is also arranged on the conveyor line 1, positioned between the anti-static component 13 and the first conveying mechanism 5. Multiple soft brushes are provided at the lower end of the PCB cleaning component 14.
[0026] The above scheme involves placing the PCB board to be coated on conveyor line 1, scanning the PCB board with scanner 12, and then conveying it to the static discharge component 13 to remove static electricity from the PCB board, preventing component burnout, performance degradation, or failure caused by electrostatic discharge. The board is then continuously conveyed to the PCB cleaning component 14 to clean the PCB board, removing surface oil, impurities, and uneven materials. This ensures that the coating material is evenly covered on the circuit board, improving film adhesion and reducing air bubbles, cracks, and peeling. This improves the accuracy, flatness, and bonding quality of the backlight coating. The soft brush design of the PCB cleaning component 14 allows for cleaning of hard-to-reach areas, gently removing tiny dust particles, solder residue, and other minor contaminants, preventing damage to components during cleaning. After passing through scanning, static discharge component 13, and PCB cleaning component 14, the first transport mechanism 5 moves the PCB board to the fixture transfer mechanism 2.
[0027] like Figure 1 , Figure 2 As shown, the fixture transfer line includes a fixture transfer mechanism 2, which includes a first driving member 21 and a fixture support platform 22 that is driven by the first driving member 21 to move along the Y direction; the fixture support platform 22 is provided with a plurality of positioning posts 23 for positioning the periphery of the fixture 11; the fixture transfer mechanism 2 is provided on the fixture transfer line.
[0028] Both the first transport mechanism 5 and the third transport mechanism 9 include fixture gripper assemblies.
[0029] Using the above scheme: the first conveying mechanism 5 moves the PCB board to the fixture transfer mechanism 2, the fixture support platform 22 supports the PCB board, and the positioning column 23 positions the PCB board. The second driving component 51 and the fixture gripper assembly on the second driving component 51 can ensure that the protective film can be accurately and firmly clamped. The multi-angle combination ensures that the protective film is torn off without damaging the conductive film, thereby improving the accuracy, flatness and bonding quality of the backlight film.
[0030] like Figures 1 to 3 As shown, a bottom film tearing mechanism 87 for tearing off the bottom isolation film of the flexible film is provided below the transfer path of the second transport mechanism 8. The bottom film tearing mechanism 87 can adopt the film tearing mechanism disclosed in the prior art, and its structure will not be described in detail in this embodiment.
[0031] The above scheme is adopted: a bottom film removal mechanism 87 for removing the bottom isolation film of the flexible film is provided below the transfer path of the second transport mechanism 8. The bottom isolation film of the flexible film is removed by the bottom film removal mechanism 87 before the film is applied.
[0032] like Figures 1 to 2 As shown, the flexible film automatic application equipment also includes a flexible film feeding unit 6 and a transfer positioning platform 7. The transfer positioning platform 7 is located on the side of the second conveying mechanism 8 away from the fixture transfer line. The flexible film feeding unit 6 and the transfer positioning platform 7 are spaced apart along the Y direction. The flexible film feeding unit 6 includes a flexible film feeding bin 61 located on the Y-direction side of the transfer positioning platform 7 and an adsorption conveying module 62 disposed above the flexible film feeding bin 61.
[0033] Using the above scheme: the adsorption and handling module 62 picks up a flexible film from the flexible film supply bin 61, and then transports it to the surface of the transfer positioning platform 7 for the first positioning. The material is separated by shaking combined with the air knife around the flexible film supply unit 6. The second handling mechanism 8 picks up the flexible film from the transfer positioning platform through the adsorption component. The bottom film removal mechanism 87 removes the bottom isolation bottom film of the flexible film and moves it above the film application station. The first CCD camera group 3 performs secondary positioning of the flexible film. The fixture transfer mechanism 2 moves the PCB board below the film application station and rolls the flexible film onto the PCB board.
[0034] The film application process is as follows: The PCB board to be filmed is placed on the surface of conveyor line 1. Conveyor line 1 transports the PCB board, and scanner 12 scans the PCB board. Conveyor line 1 continues to transport the PCB board to the anti-static component 13 and PCB cleaning component 14 for anti-static and cleaning. The first transport mechanism 5 transports the fixture 11 from conveyor line 1 to the loading station and places it on the fixture transfer mechanism 2. Then, the fixture transfer mechanism 2 transfers the PCB board from the loading station to the PCB vision positioning station 20. The second CCD camera group 4 at the PCB vision positioning station 20 performs visual positioning of the PCB board. During the above steps, the adsorption transport module 62 picks up a flexible film from the flexible film supply bin 61 and then transports it to the surface of the transfer positioning platform 7. The first physical positioning is performed. The adsorption and handling module 62 can separate the flexible film by shaking in combination with the air knife around the flexible film feeding unit 6. The second handling mechanism 8 picks up the flexible film from the transfer positioning platform 7 through the adsorption component and moves it above the film application station 10. The first CCD camera group 3 performs secondary visual positioning of the flexible film on the adsorption component. The fixture transfer mechanism 2 moves the PCB board below the film application station 10. The second handling mechanism 8 rolls and pastes the flexible film onto the PCB board. After the film application is completed, the fixture transfer mechanism 2 carries the PCB board and moves it to the unloading station, that is, below the third handling mechanism 9. The third handling mechanism 9 takes the PCB board out from the fixture transfer mechanism 2 and transports it to the conveyor line 1. The PCB board is then transported out through the conveyor line 1 to achieve unloading.
