The feeding platform 2 is provided with a separation plate 16. The winding wheel 18 is driven and connected to the feeding motor 17. The feeding tray 13 feeds the material roll and moves it to the separation plate 16 via the guide shafts 14 to separate the film onto the feeding platform 2. Then, the winding wheel 18 performs waste treatment on the material strip 15.

[0037] Specifically, the take-up reel 18 is driven and connected to the feed motor 17. The feed motor 17 drives the take-up reel to rotate and pull the material belt 15 back. The unloading tray 13 unloads the material belt 15 so that it moves to the separation plate 16 via the guide shaft 14.

The two lifting cylinders 41 simultaneously drive the rubber wheels to roll and press the two sides of the product 7 so that the two ends of the film are attached to the two sides of the product 7, thereby completing the film application operation of the end plate product 7. This achieves semi-automation with mechanical assistance, which can be operated by one worker and is suitable for mass production.

[0045] In one embodiment of this utility model, a detection frame 51 is provided on the pressing frame 5, and a detection sensor 52 for detecting the position of the product 7 is provided on the detection frame 51.

At the same time, it can be reused for products 7 of the same model and specifications, with wide applicability and high production efficiency.

[0053] Usage process

[0054] The take-up reel 18 is driven by the feeding motor 17. The feeding motor 17 drives the take-up reel to rotate and pull the material belt 15 back. The unloading tray 13 unloads the material belt 15, allowing it to move to the separating plate 16 via the guide shaft 14. Under the action of the separating plate 16, the material belt 15 peels the film onto multiple receiving blocks 23 to form a receiving surface. The anti-stick coating on the receiving surface 24 can prevent the film from sticking to the receiving blocks 23. The waste material belt 15 passes through the material belt 15 channel and is guided by the guide shaft 14. The take-up reel 18 takes up the material belt 15. The linear motor 31 and the upper and lower cylinders 32 are set perpendicular to each other in the direction of movement, so that the linear motor 31 and the upper and lower cylinders 32 form a two-axis motion module. Under the drive of the linear motor 31 and the upper and lower cylinders 32, the picking plate 33 picks up the film and brings the product 7 close to the positioning plate 61. The pushing cylinder 65 drives the pushing plate 66 to press and position the product 7 on the positioning plate. On 61, the limiting cylinders 63 on both sides drive the limiting blocks 64 to clamp and position the product 7 on both sides, thereby completing the positioning of the product 7 around its perimeter, preventing shaking during film application and movement, and ensuring the end plate application effect. The linear module 53 drives the positioning fixture 6 to move to the position of the feeding platform 2. The linear motor 31 and the upper and lower cylinders 32 form a two-axis motion module to apply the film to the product 7. The linear module 53 drives the positioning fixture 6 and the product 7 with the film applied to move to the pressing station. The two lifting cylinders 41 synchronously drive the rubber wheels to roll and press the two sides of the product 7, so that the two ends of the film are attached to the two sides of the product 7, thereby completing the film application operation of the end plate product 7. This realizes the semi-automation of mechanical assistance, which can be operated by one worker and is suitable for mass production. Compared with manual film application, the film application effect is more perfect, the film application speed is faster, saving time and labor, ensuring the accuracy and stability of the film application process, and reducing the scrap rate.
