[0002] After the keyboard is processed, it is necessary to use a hot melt film sticking machine to stick a film on the top of the keyboard after production and processing, so that the hot melt adhesive film can protect the top of the keyboard after production. Subsequently, the keyboard with the film is assembled with the keycap through a key pressing machine;

[0003] In the process of using the existing hot melt film sticking mechanism, in order to ensure the quality of film sticking, it is necessary to scrape the hot melt adhesive film flat on the top of the keyboard through a scraping plate, and then press it down through the hot pressing plate at the top to heat and bond the hot melt adhesive film to the top of the keyboard. Since in the actual use process, the scraping plate and the hot pressing plate are in two working states, after scraping the entire keyboard, the hot pressing plate at the top can be used to perform hot pressing operation on the hot melt adhesive film and the keyboard. As a result, the hot pressing cannot be carried out in time after scraping the mold, and the hot melt adhesive film is prone to bulging, reducing the film sticking quality of the keyboard. In view of the deficiencies of the existing technology, we propose a keyboard hot melt film sticking mechanism to solve the above problems. Content of the Utility Model

[0027] The driving unit is located at the top of the film pasting plate 4 and drives the film pasting plate 4 to move for pasting the film onto the keyboard. During use, the keyboard plate to be pasted is placed inside the limiting frame 201, and the film to be pasted is flatly placed on the top of the keyboard. First, the first cylinder 202 at the top drives the fixed frame 3 at the bottom to move down, bending the four sides of the film on the outer peripheral wall of the keyboard to preliminarily press the film at the top. Subsequently, the second cylinder 304 at the top drives the film pasting plate 4 and the hot pressing plate 2 to move down together, so that the bottoms of the film pasting plate 4 and the hot pressing plate 2 are mutually attached to the top of the keyboard. The driving unit drives the film pasting plate 4 and the hot pressing plate 2 to be slidably connected to the top of the keyboard. After the film can be smoothed on the top of the keyboard by the front film pasting plate 4, the smoothed film and the keyboard can be hot pressed by the subsequent hot pressing plate 2, thereby realizing the film pasting work on the film and the keyboard.
