Description

Technical Field

[0001] This utility model relates to the field of display screen processing technology, specifically to an automated ejector pin film-removing device for the terminal area of ​​a flexible OLED screen. Background Technology

[0002] In the production of flexible OLED screens, a protective film needs to be applied to the terminal area for process protection, and this film must be precisely removed before final assembly. Traditional film removal relies on manual operation. Flexible screens are thin and easily deformed, and uneven manual force can easily damage the circuitry in the terminal area or leave film residue. Furthermore, manual operation is inefficient and inconsistent, making it difficult to meet the demands of mass production. Existing automated equipment is mostly designed for rigid screens and is not well-suited for the small-area, high-precision film removal of flexible screen terminal areas. This can easily lead to positioning errors or film breakage, hindering the improvement of yield and efficiency in flexible OLED screen production. Therefore, a dedicated automated film removal solution is urgently needed.

[0003] The existing devices have low positioning accuracy, which can lead to failure during the film removal process due to inaccurate positioning. This may result in screen damage. The devices cannot accurately align with the gripping points of the protective film, which can easily lead to misalignment or incorrect gripping, resulting in a high failure rate for film removal. In addition, the existing devices rely on manual intervention, which carries high operational risks, takes a long time to adjust, and has poor consistency in manual adjustment, resulting in large differences in the film removal effect of the same batch of screens. Utility Model Content

[0004] The purpose of this invention is to provide an automated ejector pin film-removing device for the terminal area of ​​a flexible OLED screen, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated pin tearing device for the terminal area of ​​a flexible OLED screen, comprising a base plate, a worktable fixedly connected to the top of the base plate, support feet fixedly connected to the left and right ends of the bottom of the base plate, an auxiliary rotation mechanism provided on the surface of the worktable, and an automated pin tearing mechanism provided on the surface of the worktable, the automated pin tearing mechanism comprising a flexible OLED screen fixing component and an automatic tearing and recycling component; The automatic film-tearing and recycling assembly includes a fixing frame, which is fixedly connected to the rear end of the top of the workbench. A first fixing frame is fixedly connected to the top front of the fixing frame. A first sliding column is fixedly connected to the center of the inner end of the first fixing frame. A first sliding seat is provided on the surface of the first sliding column. A first electrically controlled telescopic rod is installed at the bottom inside the first fixing frame. A connecting support is fixedly connected to the front of the first sliding seat. An outer fixing seat is fixedly connected to the top and bottom front of the connecting support. A second sliding column is fixedly connected to the inner end of the outer fixing seat. A second sliding seat is provided on the surface of the second sliding column. A second electrically controlled telescopic column is installed on the right side of the inner end of the outer fixing seat. A glue roller mounting seat is fixedly connected to the front of the second sliding seat. A glue roller mounting seat is installed at the inner end of the glue roller mounting seat. The device is equipped with a roller mounting base. A second fixed frame is fixedly connected to the left side of the inner end of the fixed frame. An internal screw is rotatably connected inside the second fixed frame. A servo-controlled motor is installed on the back of the second fixed frame. A third sliding seat is provided on the surface of the internal screw. An external connecting frame is fixedly connected to the right side of the third sliding seat. A pneumatic gripper is installed on the front of the external connecting frame. A film storage box is fixedly connected to the left side of the back of the worktable. With the help of a first electrically controlled telescopic rod in the first fixed frame, the first sliding seat can be driven to slide up and down along the first sliding column, thereby driving the connecting support and subsequent roller components to achieve height adjustment. At the same time, a second electrically controlled telescopic column in the external fixed seat can push the second sliding seat to move left and right along the second sliding column to adjust the horizontal position of the roller. This multi-dimensional adjustment method can precisely adapt to flexible OLED screens of different sizes and specifications, ensuring that the rollers can accurately adhere to the protective film on the screen surface, improving the accuracy of positioning before film removal. The servo control motor in the second fixed frame drives the built-in screw to rotate, causing the threaded third sliding seat to drive the external connecting frame and pneumatic gripper to move stably. This can precisely control the position of the pneumatic gripper to grasp the protective film, avoiding film removal failure or screen damage due to gripping deviation. The automatic film removal and recycling component enables precise adjustment to adapt to different screen specifications. Film removal is performed by the rollers, achieving automated film removal without manual intervention. This significantly improves the efficiency of film removal in the terminal area of ​​flexible OLED screens, reduces labor costs, and improves efficiency while ensuring environmental cleanliness.

This fixing method provides uniform and stable adsorption force from all four corners of the screen, effectively preventing displacement and lifting during the film removal process. This provides a stable foundation for subsequent precise film removal. Visual recognition cameras installed at both ends of the slide block accurately identify and locate the pre-drilled holes in the terminal area of ​​the flexible OLED screen and feed this positioning information back to the control system. Based on this feedback, the control system controls the servo motor to drive the lead screw, moving the slide block along the built-in rail. Simultaneously, the height of the ejector pin and ejector pin is adjusted via the lifting column to ensure precise alignment of the ejector pin with the pre-drilled holes in the terminal area.

[0023] In actual operation, when this device is used, the flexible OLED screen 6, which requires film removal, is mounted on the top of the carrier plate 513.

During the film-peeling process, the control motor 44 drives the rotating shaft 45 and the rotating base 42 to rotate. After a set of flexible OLED screens 6 has finished peeling off the film, the rotation drives the next set of flexible OLED screens 6 to the work station. The staff removes and reloads the flexible OLED screens 6 after peeling off the film. The film storage box 52091 set on the left side of the back of the workbench 2 can collect the peeled protective film in a centralized manner to avoid the protective film from being scattered randomly and causing a messy working environment. It also facilitates the unified treatment of the protective film in the future and reduces environmental pollution.
