Technical Field
[0001] This utility model relates to the field of thin film production technology, specifically a pressing device for thin film production. Background Technology
[0002] This method can only press the main body of the film, and cannot focus on the edges, easily leading to problems such as edge lifting and loose adhesion due to insufficient edge pressing force, affecting product sealing and service life. Furthermore, in scenarios involving bonding irregularly shaped parts (such as substrates with a certain curvature) to the film, frequent replacement of specialized pressing heads is required, increasing mold costs and extending production changeover time, making it difficult to meet the needs of multi-specification, small-batch production. Therefore, those skilled in the art have provided a pressing device for film production to solve the problems mentioned in the background art. Utility Model Content
[0003] The purpose of this invention is to provide a pressing device for thin film production to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A pressing device for film production includes a base plate, a fixed frame fixedly connected to the upper end of the base plate, a carrier box fixedly connected to the upper end of the fixed frame, a main cylinder disposed inside the carrier box, a pressing component disposed at the output end of the main cylinder, a pressing head connected to the main cylinder through the pressing component, and an oscillating component for adjusting the angle of the pressing head disposed on the carrier box and the pressing head.
[0005] Furthermore, the pressing assembly includes a bearing plate, a fixed plate, a second sliding block, and a second limiting rod. The fixed plate is fixedly connected to the lower end face of the bearing box, the second sliding block is fixedly connected to the fixed plate, the second limiting rod is slidably connected to the second sliding block, and the bearing plate is fixedly connected to the surface of the second limiting rod.
[0006] Furthermore, the pressing assembly also includes a rotating plate, a connecting plate, and a force-applying plate. The force-applying plate is fixedly connected to the output end of the main cylinder. One end of the force-applying plate is fixedly connected to the bearing plate. The connecting plate is fixedly connected to the surface of the bearing plate. The rotating plate is rotatably connected to the connecting plate, and the lower end of the rotating plate is fixedly connected to the pressing head.
[0007] Furthermore, the swing assembly includes a secondary cylinder, a connecting rod, and a connecting anchor point. The secondary cylinder is fixedly connected inside the bearing housing, and the connecting rod is rotatably connected to the output end of the secondary cylinder. The connecting anchor point is fixedly connected to the upper surface of the pressing head, and the connecting rod is rotatably connected to the connecting anchor point.
[0008] Furthermore, the upper surface of the base plate is also provided with a feeding assembly, which includes a sliding plate, a film support platform, an adjusting cylinder, and an L-shaped plate. The adjusting cylinder is fixedly connected to the upper surface of the base plate, the output end of the adjusting cylinder is fixedly connected to the L-shaped plate, the upper surface of the L-shaped plate is fixedly connected to the sliding plate, and the upper surface of the sliding plate is provided with a film support platform.
[0009] Furthermore, the feeding assembly also includes a first sliding block and a first limiting rod. The first limiting rod is fixedly connected to the upper surface of the base plate, and the first sliding block is slidably connected to the first limiting rod. The upper surface of the first sliding block is fixedly connected to the sliding plate.
[0010] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: 1. The auxiliary cylinder can flexibly adjust the tilt angle of the pressing head (such as fine-tuning the angle within the range of 0-15°) by rotating the connecting rod and the anchor point connected to the pressing head through the rotational engagement. This allows for a secondary pressing at the edges when tilted, ensuring that there are no dead corners in the pressing process. 2. In special scenarios such as curved edge pressing of film and bonding of irregular parts, multi-angle pressing can be achieved without changing the pressing head, which not only reduces the cost of mold replacement, but also shortens the production changeover time and improves the adaptability of the equipment to diverse production needs; 3. Automated operation reduces close contact between operators and the pressing head. Compared with the traditional manual pressing of the pressing head, it reduces safety hazards during equipment operation (such as the risk of accidental finger contact with the pressing mechanism) and also avoids situations where the pressing is not in place due to operator error.

[0012] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0013] Please see Figures 1-4 This utility model provides an embodiment of a pressing device for film production, including a base plate 1. A fixing frame 4 is fixedly connected to the upper end of the base plate 1. A bearing box 5 is fixedly connected to the upper end of the fixing frame 4. A main cylinder 8 is arranged inside the bearing box 5. A pressing component is arranged at the output end of the main cylinder 8. The main cylinder 8 is connected to a pressing head 16 through this pressing component. A swing component for adjusting the angle of the pressing head 16 is also arranged on the bearing box 5 and the pressing head 16.
[0014] In this embodiment, the pressing assembly includes a bearing plate 11, a fixing plate 19, a second sliding block 20, and a second limiting rod 21. The fixing plate 19 is fixedly connected to the lower end face of the bearing housing 5. The second sliding block 20 is fixedly connected to the fixing plate 19, and the second limiting rod 21 is slidably connected to the second sliding block 20. The bearing plate 11 is fixedly connected to the surface of the second limiting rod 21. The pressing assembly also includes a rotating plate 13, a connecting plate 17, and a force-applying plate 18. The output end of the main cylinder 8 is fixedly connected to the force-applying plate 18. One end of the force-applying plate 18 is fixedly connected to the bearing plate 11. The connecting plate 17 is fixedly connected to the surface of the bearing plate 11. A rotating plate 13 is rotatably connected to the upper part of the pressing head 16, and the lower end of the rotating plate 13 is fixedly connected to the pressing head 16. The main cylinder 8 is started through the control panel. The output end of the main cylinder 8 pushes the force plate 18, which drives the bearing plate 11 and the second limit rod 21 to descend vertically. At this time, the second sliding block 20 provides a limiting effect. The connecting plate 17 on the surface of the bearing plate 11 drives the rotating plate 13 and the pressing head 16 to descend synchronously until the pressing head 16 contacts the film surface, completing the initial full pressing and ensuring that the main body area of the film is tightly bonded. During this process, the auxiliary cylinder 9 operates synchronously, and the pressing head 16 does not shift in angle through the connecting rod 10 and the connecting anchor point 12.
[0015] In this embodiment, the swing assembly includes a secondary cylinder 9, a connecting rod 10, and a connecting anchor point 12. The secondary cylinder 9 is fixedly connected inside the bearing housing 5, and the output end of the secondary cylinder 9 is rotatably connected to the connecting rod 10. The upper surface of the pressing head 16 is fixedly connected to the connecting anchor point 12, and the connecting rod 10 is rotatably connected to the connecting anchor point 12. After the initial pressing is completed, the main cylinder 8 is not activated to lift the pressing head 16. Instead, the operating mode of the secondary cylinder 9 is activated through the control panel. Based on the edge characteristics of the rectangular film, the output end of the secondary cylinder 9 pulls the connecting anchor point 12 on the pressing head 16 through the connecting rod 10, causing the pressing head 16 to tilt around the rotating connection between the connecting plate 17 and the rotating plate 13. After the pressing head 16 tilts, its edge is in close contact with the edge of the film. This tilted state is maintained for 2-3 seconds, and a secondary pressing is performed on the edge.
[0016] In this embodiment, a feeding assembly is also provided on the upper surface of the base plate 1. The feeding assembly includes a sliding plate 2, a film support platform 3, an adjusting cylinder 14, and an L-shaped plate 15. The adjusting cylinder 14 is fixedly connected to the upper surface of the base plate 1, and the L-shaped plate 15 is fixedly connected to the output end of the adjusting cylinder 14. The sliding plate 2 is fixedly connected to the upper surface of the L-shaped plate 15, and the film support platform 3 is provided on the upper surface of the sliding plate 2. The feeding assembly also includes a first sliding block 6 and a first limiting rod 7. The first limiting rod 7 is fixedly connected to the upper surface of the base plate 1, and the first sliding block 6 is slidably connected to the first limiting rod 7. The upper surface of the first sliding block 6 is fixedly connected to the sliding plate 2. The rectangular PET film to be pressed is laid flat on the film support platform 3, and the adjusting cylinder 14 of the feeding assembly is activated. The adjusting cylinder 14 drives the L-shaped plate 15. The template moves the sliding plate 2 along the first limit rod 7 toward the pressing area until the film carrier platform 3 is completely below the pressing head 16. At this time, the equipment automatically triggers the positioning sensor, and the adjusting cylinder 14 stops running, completing the feeding and positioning.
[0017] When the device is working, the first step is to load the material: the rectangular PET film to be pressed is laid flat on the film support platform 3. The adjusting cylinder 14 of the loading component is activated. The adjusting cylinder 14 drives the L-shaped plate to move the sliding plate 2 along the first limiting rod 7 on the bottom plate 1 (which slides in conjunction with the first sliding block 6) towards the pressing area. When the film support platform 3 is completely below the pressing head 16, the positioning sensor is triggered, the adjusting cylinder 14 stops, and the loading and positioning are completed. Then, the initial full pressing is started. The main cylinder 8 is turned on through the control panel. The output end of the main cylinder 8 pushes the force plate 18, which drives the support plate 11 and the second limiting rod 21 on the surface (along the second sliding block 20 on the fixed plate 19 at the lower end of the support box 5) to descend vertically. At the same time, the connecting plate 17 on the support plate 11 drives the rotating plate 13 and the pressing head 16 to descend synchronously until the pressing head 16 contacts the film surface. During this process, the auxiliary cylinder 9 operates synchronously, using the connecting rod 10 and the connecting anchor point 12 to ensure that the pressing head 16 has no angular deviation, ensuring a tight fit between the film body and the body. Finally, a secondary edge pressing is performed. After the initial pressing, the pressing head 16 is not lifted, and the auxiliary cylinder 9 is activated. The output end of the auxiliary cylinder 9 pulls the connecting anchor point 12 on the pressing head 16 through the connecting rod 10, causing the pressing head 16 to tilt around the connection between the connecting plate 17 and the rotating plate 13, with its edge in close contact with the edge of the film. This is maintained for 2-3 seconds, focusing on a secondary pressing of the edge to complete the single pressing operation.
[0018] The auxiliary cylinder 9, through the rotating engagement of the connecting rod 10 and the anchor point 12 on the pressing head 16, can flexibly adjust the tilt angle of the pressing head 16 (such as fine-tuning within the range of 0-15°). This allows for focused secondary pressing at the edges when tilted, ensuring no dead corners in the pressing process. In special scenarios such as curved edge pressing of films and bonding of irregularly shaped parts, multi-angle pressing can be achieved without replacing the pressing head 16. This not only reduces mold replacement costs but also shortens production changeover time, improving the equipment's adaptability to diverse production needs. Automated operation reduces close contact between operators and the pressing head 16. Compared to the traditional manual pressing of the pressing head 16, this reduces safety hazards during equipment operation (such as the risk of accidental finger contact with the pressing mechanism) and also avoids incomplete pressing due to operator error.
