[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figures 1-4 A mobile phone frame film application device includes a housing 1, a workbench 2 fixedly mounted on the top of the housing 1, a human-machine interface 3 for interaction on the front of the housing 1, a two-hand start button 4 and an emergency stop button 5 respectively mounted on the housing 1, and a mobile phone frame 601 and a protective film 701 respectively mounted on the workbench 2; the starting point and ending point of the film application on the mobile phone frame 601 can be adjusted by setting parameters through the human-machine interface 3.
[0022] The top of the workbench 2 is equipped with a rotating device 6 for rotating the mobile phone frame 601, a film winding device 7 for winding the protective film 701, and a film pressing device 8 for pressing the protective film 701.
[0023] The rotating device 6 includes a pressure-holding cylinder support 602 fixedly connected to the top surface of the worktable 2. A pressure-holding cylinder 603 is fixedly connected to the pressure-holding cylinder support 602. The pressure-holding cylinder 603 drives the pressure ring 604 to descend and press the product, preventing the mobile phone frame 601 from detaching from the product fixture 605 during the film application process. The pressure ring 604 is rotatably connected to the bottom output end of the pressure-holding cylinder 603. A stepper motor 606 is fixedly installed on the top of the worktable 2. A coupling 607 is fixedly installed on the top output end of the stepper motor 606. The product fixture 605 is fixedly connected to the top of the coupling 607, and the mobile phone frame 601 is fixedly installed on the product fixture 605.
[0024] The film winding device 7 includes a damping plate column 702 mounted above the worktable 2. A film roll central shaft 706 is rotatably mounted on the top of the worktable 2. A film roll base 703 and a film roll pressure plate 705 are fixedly mounted on the film roll central shaft 706. Corresponding damping springs 704 are mounted on the damping plate column 702. The damping springs 704 and the film roll base 703 are in contact. The damping force is adjusted by adjusting the angle of the damping plate column 702, thereby adjusting the tension of the protective film 701. Guide column one 709 and guide column two 712 are rotatably mounted above the worktable 2. An upper guide ring one 707 and a lower guide ring one 708 are fixed on guide column one 709. The upper guide ring one 707 and the lower guide ring one 708 guide the protective film 701 to prevent vertical deviation. An upper guide ring two 710 and a lower guide ring two 711 are fixed on guide column two 712. After the protective film 701 changes direction through guide post 1 709 and guide post 2 712, the tension of the film is increased, so that the protective film 701 always remains straight during the application process.
[0025] The protective film 701 is attached to guide post 1 709 and guide post 2 712.
[0026] The film pressing device 8 includes a film-pulling linear slide rail 801 fixedly mounted above the worktable 2. A film-pulling pneumatic finger 802 slides on the film-pulling linear slide rail 801. A film-pulling lifting cylinder 803 and a film-pulling lateral movement cylinder 805 are respectively mounted above the worktable 2. A protective film clamp 804 is mounted on the film-pulling pneumatic finger 802. The film-pulling pneumatic finger 802 drives the protective film clamp 804 to clamp the protective film 701 pulled out of the film roll. The film-pulling lateral movement cylinder 805 pulls the film forward, and the film pressing cylinder 809 drives the film pressing roller 811 to press the protective film 701 against the mobile phone frame 601 on the rotating device 6. The film-pulling lateral movement cylinder 805 and the film-pulling pneumatic finger 802 are fixedly connected. A protective film cutter 806 and a film cutting cylinder 807 are fixedly mounted above the worktable 2. A film pressing cylinder 809 and a film pressing linear slide rail 810 are mounted on the horizontal side of the film cutting cylinder 807.
[0027] A pressure spring 808 is provided at one end of the pressure cylinder 809, and a pressure roller 811 is provided at the other end of the pressure spring 808. The pressure roller 811 presses the protective film 701 against the mobile phone frame 601 through the pressure spring 808, so that the pressure roller 811 always keeps the protective film 701 and the product frame in a tight state during the product rotation and film application process.
[0028] The functional principle of this utility model can be explained through the following operation methods:
[0029] During use, the protective film roll is placed on the film roll base 703 and flattened by the film roll pressure plate 705. The protective film 701 pulled out of the film roll is deflected by guide post 1 709, with upper guide ring 1 707 and lower guide ring 1 708 guiding the protective film 701 to prevent vertical deviation. It is then deflected again by guide post 2 712, with upper guide ring 2 710 and lower guide ring 2 711 guiding the protective film 701 to prevent vertical deviation. After the protective film 701 changes direction by guide post 1 709 and guide post 2 712, the tension of the film is increased, ensuring that the protective film 701 remains straight throughout the application process. The damping spring 704 contacts the film roll base 703, and the damping force is adjusted by adjusting the angle of the damping spring column 702, thereby adjusting the tension of the protective film 701.
[0030] Rotating device 6: The mobile phone frame 601 is placed on the product fixture 605. The product fixture 605 is connected to the stepper motor 606 through the coupling 607. The pressure holding cylinder 603 drives the pressure ring 604 to descend and press the product, preventing the mobile phone frame 601 from detaching from the product fixture 605 during the film application process.
[0031] Film pressing device 8: The pneumatic finger 802 drives the protective film clip 804 to clamp the protective film 701 pulled out of the film roll. The film pulling cylinder 805 pulls it forward, and the film pressing cylinder 809 drives the film pressing roller 811 to press the protective film 701 against the mobile phone frame 601 on the rotating device 6. The protective film clip 804 is released, and the film pulling lifting cylinder 803 descends, driving the protective film clip 804 to descend. The stepper motor 606 on the rotating device 6 rotates, driving the mobile phone frame 601 on the product fixture 605 to apply the film. The film pressing roller 811 on the film pressing device 8 presses the protective film 701 against the mobile phone frame 601 through the film pressing spring 808, so that the film pressing roller 811 always keeps the protective film 701 and the product frame in a tight state during the product rotation and film application process. The starting point and ending point of the film application on the mobile phone frame 601 can be adjusted by setting parameters through the human-machine interface 3.
[0032] After the film application is completed, the film-pulling cylinder 805 retracts, the protective film clamp 804 rises to clamp the film, and the film-cutting cylinder 807 drives the protective film cutter 806 to extend and cut the protective film 701, thus completing the film application.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
