[0001] The utility model relates to the technical field of electronic touch screen production, in particular to an electronic touch screen glue scraping device. Background Art

[0002] An electronic touchscreen integrated into an LCD (Liquid Crystal Display) screen, commonly referred to as a touch LCD, is a display device that combines touch-sensing technology with liquid crystal display technology. This allows a touch LCD screen to not only display images but also respond to touch input. In a touch LCD, the display portion of the liquid crystal layer requires a polarizer. This polarizer controls the direction of light, allowing the liquid crystal molecules to effectively adjust the light's transmittance. Damage to the polarizer affects the display, and aging of the internal gelatin can cause localized yellow spots, necessitating replacement of the polarizer.

[0003] Currently, when replacing a polarizer, it is first necessary to separate the liquid crystal display layer of the touch LCD, and then use a scraper to scrape off the old polarizer on the screen. After scraping, the old polarizer will leave some glue or adhesive on the screen, which requires a scraping device to clean up these residues to ensure that the new polarizer is firmly adhered. The existing scraping device usually makes the scraper contact with the screen and controls the scraper to gradually advance to scrape off the residue on the screen. However, the scraper of the existing device contacts the screen at both ends during the advancement process, resulting in stress concentration and easy scratching of the screen.

[0004] Therefore, in order to solve the above problems, an electronic touch screen scraping device has been developed, which can disperse the stress when the scraper contacts the screen and reduce the risk of scratching. Summary of the Invention

At this time, the height of the screen placed on the base frame 1 is detected by the sensor 6, and the telescopic end of the first electric push rod 4 is controlled to drive the lifting platform 5 to move up and down for adjustment, so that the lifting platform 5 and the screen maintain the same horizontal height. After the adjustment is completed, the telescopic end of the second electric push rod 13 drives the mounting frame 11 and the scraper 12 to move downward until the scraper 12 contacts the lifting platform 5, and then the first driving component 9 drives the slide 8 to move forward, and the slide 8 moves The scraper 12 is driven by the movement to advance the mounting frame 11 and the scraper 12. Since the scraper 12 is set at an angle, one end of the scraper 12 first contacts the screen when advancing, and then gradually transitions to contact with the other end, which can disperse the stress when the scraper 12 contacts the screen, thereby scraping off the colloid remaining on the screen. After the scraper 12 scrapes off the colloid remaining on the screen, some of the colloid may adhere to the scraper 12. The second driving component 16 can be used to drive the slider 14 to move on the mounting frame 11.
