Description

Technical Field

[0001] This utility model relates to the field of liquid crystal displays, and in particular to a polarizer stripping device for a liquid crystal display panel. Background Technology

[0002] Polarizing film stripping equipment is used to peel polarizing film from the substrate of devices such as liquid crystal displays. Common polarizing film stripping equipment includes polarizing film stripping machines. The polarizing film is first separated from one corner of the display panel using a scraper, and then the polarizing film with the corner is placed into the separation port. The polarizing film is then evenly peeled off by the stripping roller and the stripping blade together.

[0003] Liquid crystal display panels often cannot be smoothly lifted at the corners. Lifting at a unstable angle can easily damage the liquid crystal display substrate, making it impossible for the panel stripping machine to quickly lift the corners before use, which greatly reduces work efficiency. To address this issue, a polarizer stripping device for liquid crystal display panels is proposed. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a polarizer peeling device for a liquid crystal display panel, comprising a peeling machine 1. The peeling machine 1 includes internal structures such as pressure rollers, transmission rollers, and peeling blades, all of which are prior art and not improvements to this application, and will not be described in detail here. The peeling machine 1 is internally equipped with a lifting assembly. A lower pressure block 5 is mounted on the top of the lifting assembly, which fixes the panel. A peeling structure is mounted on the bottom of the lower pressure block 5, which raises the corner of the polarizer on the panel. A separation port 2 is provided on the outer side of the peeling machine 1. The polarizer corner of the liquid crystal display panel, after being raised, is placed into the separation port 2, and the polarizer is evenly torn apart by the internal structure of the peeling machine 1. The top of the peeling machine 1 is fixedly connected to a fixing block 20. First, the LCD display panel is placed between the fixing blocks 20. The peeling structure includes a moving component and a scraping component. The scraping component includes a slider 10. A fixing shaft 11 is fixedly connected to the bottom of slider 10. Slider 10 drives the fixing shaft 11 to move. A blade 12 is slidably connected to the outer periphery of the fixing shaft 11. When the fixing shaft 11 moves, it slides in the middle of the blade 12, simultaneously driving the blade 12 to move. A fixing shaft 2 13 is slidably connected to the middle of the blade 12. A slider 2 14 is fixedly connected to the end of the fixing shaft 2 13. The interior of the lower pressure block 2 7... A slide bar 15 is fixedly connected, and a slider 14 is slidably connected to the outer periphery of the slide bar 15. The slider 14 moves together with the blade 12 to fix the direction and position of the blade 12 and prevent the blade 12 from deviating. The moving component includes a motor 8, which is fixedly connected inside the lower pressure block 5. A screw 9 is fixedly connected to the output end of the motor 8, and a slider 10 is threadedly connected to the outer periphery of the screw 9. When the motor 8 is started, it drives the screw 9 to rotate. The rotating screw 9 drives the slider 10 to move, thereby moving the blade 12. The blade 12 scrapes the fixed liquid crystal display panel, causing the polarizer to quickly angle.

[0034] Reference Figure 1 , Figure 4 and Figure 5The lifting assembly includes a second motor 19, with a screw 18 fixedly connected to the output end of the second motor 19. Starting the second motor 19 drives the screw 18 to rotate. A telescopic rod 4 is threadedly connected to the outer circumference of the screw 18. The rotating screw 18 drives the telescopic rod 4 to rise and fall. The telescopic rod 4 is fixedly connected to the bottom of the first lower pressure block 5. The rising and falling telescopic rod 4 drives the first lower pressure block 5 to press down. A support rod 3 is slidably connected to the outer circumference of the telescopic rod 4. The support rod 3 is fixedly connected to the middle of the sheet-removing machine 1, providing stable support for the top structure. A connecting rod 6 is fixedly connected to the outer side of the first lower pressure block 5. A second lower pressure block 7 is fixedly connected to the end of the connecting rod 6. The rotating and moving first lower pressure block 5, driven by the second screw 18, moves the second lower pressure block 7 together with the connecting rod 6. The telescopic rod 4 at the bottom of the second lower pressure block 7 only slides within the support rod 3. The outer sides of both the first lower pressure block 5 and the second lower pressure block 7 are fixedly connected. A soft block 16 is fixedly connected to the panel. The soft block 16 presses down on the panel to fix it and prevent scratches. When it is necessary to raise the corners of the LCD panel, the panel is placed between the fixed blocks 20. The motor 2 19 is started to drive the pressing blocks 5 and 7 to press down together, so that the soft block 16 presses on the panel for fixation. Then, the panel is scraped and raised by the moving blade 12. A blower pipe 17 is fixedly connected to the outside of the pressing blocks 5 and 7. A conductive wire 22 is installed on the outer periphery of the blower pipe 17. An air inlet pipe 21 is installed on the outside of both the pressing blocks 5 and 7. The air inlet pipe 21 is connected to an external air source. The air is heated by the conductive wire 22 and blown out by the blower pipe 17 to heat the panel fixed at the bottom of the soft block 16, so that the adhesive between the LCD panel and the polarizer is softened, making it easier and faster to raise the corners and greatly improving work efficiency.

[0035] Working principle: When it is necessary to raise the corners of the LCD panel, the panel is placed between the fixing blocks 20. The motor 2 19 is started to drive the screw 2 18 to rotate. The rotating screw 2 18 drives the telescopic rod 4 to descend. The descending telescopic rod 4 drives the lower pressure block 1 5 and the lower pressure block 2 7 to press down together, so that the soft block 16 is pressed on the panel for fixation. The external air source gas enters through the air inlet pipe 21, is heated by the conductive wire 22 and blown out through the air blower pipe 17, and heats the panel fixed at the bottom of the soft block 16, so that the adhesive between the LCD panel and the polarizer is softened, making it easier and faster to raise the corners.

[0036] Then, start motor 8 to drive screw 9 to rotate. The rotating screw 9 drives slider 10 to move. Slider 10 drives fixed shaft 11 to move, thereby moving blade 12. Blade 12 scrapes the fixed LCD panel, causing the polarizer to quickly raise its angle. After the angle raising is completed, start motor 19 to drive screw 18 to rotate, causing lower pressure block 5 and lower pressure block 7 to be lifted together. Take out the panel and put the raised polarizer into the separation port 2. The polarizer is then evenly torn apart by the internal structure of the sheet removal machine 1.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
