[0033] Reference Figure 3The mounting bracket 19 is fixedly connected to the left and right sides of the middle between the front and rear inner walls of the mounting seat 1, and a collection box 18 is slidably connected between the mounting brackets 19. A handle 10 is fixedly connected to the rear side of the collection box 18. A support plate 9 is provided on the top of the scraping assembly, and a top plate 6 is fixedly connected to the top of the support plate 9. A fan 7 is penetrated and fixedly connected to the front and rear sides of the top of the top plate 6, and a nozzle 8 is penetrated and fixedly connected to the bottom of the top plate 6. The left and right sides of the top between the inner walls of the mounting seat 1 are fixedly connected The guide plate 21 is aligned with the collection box 18. After the glue removal is completed, the fan 7 is started to blow air toward the inside of the nozzle 8. The blown wind is guided by the nozzle 8, so that the glue adhered to the scraper is blown downward and falls onto the guide plate 21 or the arc guide plate 16 to prevent it from dripping on other parts of the equipment and causing equipment failure. After the collection box 18 is full of glue, the handle 10 is pulled to extract the collection box 18 from the mounting bracket 19 to facilitate the processing of the glue inside it.

[0034] Reference Figure 2 The front and rear sides of the bottom inner wall of the mounting seat 1 are fixedly connected with a mounting box 11, the right side of the mounting box 11 is fixedly connected with a servo motor 12, the output end of the servo motor 12 is fixedly connected with a bidirectional screw 13, and the bidirectional screw 13 penetrates and is rotatably connected to the mounting box 11, the outside of the bidirectional screw 13 penetrates and is threadedly connected with a nut pair 14, the top of the nut pair 14 is provided with a scraping assembly, the top of the scraping assembly is provided with a support plate 9, the scraping assembly includes a vertical rod 15, the vertical rod 15 is fixedly connected to the top of the nut pair 14, and the vertical rod 15 is fixedly connected to the arc guide plate 1 in the middle of the side adjacent to the bidirectional screw 13 6. A scraper 17 is fixedly connected to the top of one side of the vertical rod 15 adjacent to the bidirectional screw 13. The scraper 17 is wedge-shaped. The servo motor 12 is started to drive the bidirectional screw 13 to rotate, so that the vertical rod 15 drives the scraper 17 to contact the protective film, and the upper roller 4 is rotated to move the protective film. During the movement, the glue on the edge of the protective film is scraped off by the scraper 17. The glue scraped off from the protective film with a smaller volume flows into the collection box 18 through the through hole 3 on the placement table 2 and the guide plate 21. When the protective film with a volume exceeding the guide plate 21 is de-glueed, the scraped glue falls into the arc guide plate 16.

The glue scraped off from the protective film with a smaller volume flows into the mounting bracket 19 through the through hole 3 on the placement table 2 and the guide plate 21. When the protective film with a volume larger than the guide plate 21 is removed, the glue scraped off is removed. When removing glue, the scraped glue falls into the arc guide plate 16, and then the glue falls into the collection box 18 through the arc guide plate 16. After the glue removal is completed, the fan 7 is started to blow air into the inside of the nozzle 8. The blown wind is guided by the nozzle 8, so that the glue adhered to the scraper is blown downward, and then falls onto the guide plate 21 or the arc guide plate 16 to prevent it from dripping on other parts of the equipment and causing equipment failure. After the collection box 18 is full of glue, the handle 10 is pulled to extract the collection box 18 from the mounting bracket 19 to facilitate the treatment of the glue inside it.
