[0049] Usage process

[0050] The intermediate end plate 7 is placed in the fixture slot 53, the length of which is less than the length of the end plate 7, so that the intermediate end plate 7 extends out from the opening 54. The pushing cylinder 55 drives the pushing plate 56 to push and position the end plate 7 on the fixture slot 53, thereby positioning the intermediate end plate 7. The linear module 6 drives the end plate 7 on the positioning fixture 5 to be transferred to the feeding platform 2, so that the intermediate end plate 7 is positioned opposite the pressing assembly 3. The feeding motor 17 drives the take-up wheel 16 to pull and take up the material belt 14, so that the material belt 14 on the take-up wheel 16 moves to the separating plate 22 after passing through the guide shaft 13 and the damping shaft 15. The material belt 14 separates one end of the film from the material belt 14 through the separating surface at the end of the separating plate 22. At the same time, the pressing cylinder 32 drives the pressing roller 34 to press the separated end of the film tightly in the middle. On the intermediate end plate 7, the feeding motor 17 continues to drive the take-up wheel 16 to pull and collect the material strip 14. At the same time, the linear module 6 drives the end plate 7 on the positioning fixture 5 to move from the feeding platform 2 to the film application mechanism 4. Under the drive of the pressure roller 34, the film is completely attached to the upper surface of the intermediate end plate 7. The linear module 6 drives the end plate 7 with the film attached to move from the feeding platform 2 to the film application mechanism 4. The two film application cylinders 42 drive the rubber rollers 44 on the fixing frame 43 to press and apply the film to both sides of the end plate 7 simultaneously, quickly completing the three-sided application of the film. This ensures the accuracy and stability of the film application process, reduces the scrap rate, and achieves a more perfect film application effect. The film application speed is faster, saving time and effort. This utility model can be reused for products of the same model and specifications, has a wide range of applications, and high production efficiency.
