AI Technical Summary
In traditional film cutting processes, mechanical pressing mechanisms can cause scratches or deformation on the film surface, conventional conveying devices are prone to slippage and wrinkles, and the alternating cutting and feeding actions result in low equipment utilization and secondary positioning errors.
The system combines a rolling pressing mechanism, a cutting mechanism, and a negative pressure conveying mechanism. The rolling pressing mechanism presses the film material while the negative pressure conveying mechanism attracts and pulls the film material forward. This, combined with the synchronous action of laser cutting, enables continuous and stable feeding.
To avoid film material deformation and displacement, improve feeding accuracy and efficiency, reduce the heat-affected zone, and protect the integrity of film material edges.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of film material cutting technology, specifically to a laser cutting mechanism for film materials. Background Technology
[0002] Precision cutting of film materials (such as polymer films and composite films) is a critical processing step in industries such as packaging, electronics, and medical. Traditional cutting processes mostly use mechanical die-cutting or ordinary laser cutting equipment, but they have the following technical defects: mechanical pressing mechanisms use fixed pressure plates or rigid rollers, which are prone to scratches or thermal deformation of the film surface due to friction during high-speed feeding; conventional conveying devices mostly rely on friction drive, which can easily cause slippage and wrinkles for ultra-thin or low-friction film materials, resulting in insufficient feeding accuracy; the cutting process and feeding action need to be performed alternately, resulting in low equipment utilization and secondary positioning errors. Summary of the Invention
[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a laser cutting mechanism for film material, which significantly improves the overall performance of film material cutting by organically combining the rolling pressing mechanism, the cutting mechanism and the negative pressure conveying mechanism.
[0004] This utility model is achieved through the following technical solution: A laser cutting mechanism for a film material includes a rolling pressing mechanism, a cutting mechanism, and a negative pressure conveying mechanism arranged sequentially in a horizontal direction. The rolling pressing mechanism is used to roll and press the film material, the cutting mechanism is used to laser cut the film material, and the negative pressure conveying mechanism is used to adsorb the film material and pull the film material forward.
[0005] The rolling pressing mechanism includes a feeding base plate, a pressing connecting rod located above the feeding base plate, multiple rolling rollers mounted on the connecting rod and facing the feeding base plate, and a rolling pressing drive component for driving the pressing connecting rod away from or towards the feeding base plate.
[0006] The rolling pressing drive component is a cylinder.
[0007] The cutting mechanism includes a first cutting transverse drive, a second cutting transverse drive installed at the output end of the first cutting transverse drive, and a cutting device installed at the output end of the second cutting transverse drive. The output direction of the first cutting transverse drive is parallel to the output direction of the negative pressure conveying mechanism, and the output direction of the second cutting transverse drive is perpendicular to the output direction of the first cutting transverse drive.
[0008] Both the first and second cutting transverse drive components are linear motors.
[0009] The negative pressure conveying mechanism is a vacuum conveyor belt.
[0010] The beneficial effects of this utility model are: The laser cutting mechanism provided by this utility model adopts a rolling pressing method to dynamically adjust the tension of the film material, avoiding material deformation caused by traditional pressing, and ensuring that the film material is flat and without deviation during cutting; the suction force of the negative pressure conveying mechanism pulls the film material forward, which, in conjunction with the synchronous action of laser cutting, achieves continuous and stable feeding, reduces manual intervention and improves processing efficiency; in addition, the negative pressure adsorption can remove the heat and waste generated by cutting in time, reduce the range of the heat-affected zone and protect the integrity of the film material edge.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0016] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0018] Precision cutting of film materials (such as polymer films and composite films) is a critical processing step in industries such as packaging, electronics, and medical. Traditional cutting processes mostly use mechanical die-cutting or ordinary laser cutting equipment, but they have the following technical defects: mechanical pressing mechanisms use fixed pressure plates or rigid rollers, which are prone to scratches or thermal deformation of the film surface due to friction during high-speed feeding; conventional conveying devices mostly rely on friction drive, which can easily cause slippage and wrinkles for ultra-thin or low-friction film materials, resulting in insufficient feeding accuracy; the cutting process and feeding action need to be performed alternately, resulting in low equipment utilization and secondary positioning errors.
[0019] To address the aforementioned problems, this embodiment discloses a laser cutting mechanism for film materials, the structure of which is as follows: Figure 1 and Figure 2 As shown, the laser cutting mechanism includes a rolling pressing mechanism 101, a cutting mechanism 110, and a negative pressure conveying mechanism 120 arranged sequentially in the horizontal direction. The rolling pressing mechanism 101 is used to roll and press the film material, the cutting mechanism 110 is used to laser cut the film material, and the negative pressure conveying mechanism 120 is used to adsorb the film material and pull the film material forward.
[0020] Furthermore, the rolling pressing mechanism 101 includes a feeding base plate 102, a pressing connecting rod 103 located above the feeding base plate 102, a rolling roller 104 mounted on the connecting rod and facing the feeding base plate 102, and a rolling pressing drive member 105 for driving the pressing connecting rod 103 away from or near the feeding base plate 102. Preferably, the rolling pressing drive member 105 is a cylinder.
[0021] In this embodiment, the film material enters the rolling pressing mechanism 101 from the external storage mechanism. The rolling pressing drive 105 drives the pressing connecting rod 103 to descend, so that the rolling roller 104 presses the film material against the feeding base plate 102. The film material is pulled with the assistance of the negative pressure conveying mechanism 120, which is preferably a vacuum conveyor belt. After the film material has moved a certain distance, the negative pressure conveying mechanism 120 stops conveying, and the cutting mechanism 110 performs laser cutting on the film material, thereby realizing the intermittent supply of sheet material.
[0022] Specifically, the cutting mechanism 110 includes a first cutting transverse drive 111, a second cutting transverse drive 112 mounted on the output end of the first cutting transverse drive 111, and a cutting device 113 mounted on the output end of the second cutting transverse drive 112. The output direction of the first cutting transverse drive 111 is parallel to the output direction of the negative pressure conveying mechanism 120, and the output direction of the second cutting transverse drive 112 is perpendicular to the output direction of the first cutting transverse drive 111. In this embodiment, the first cutting transverse drive 111 and the second cutting transverse drive 112 are preferably linear motors. The structure of the cutting device 113 and the principle of detecting and cutting the film material are existing technologies and will not be described in detail here.
[0023] In summary, the laser cutting mechanism provided in this embodiment dynamically adjusts the film tension using a rolling pressing method, avoiding material deformation caused by traditional pressing and ensuring that the film is flat and without deviation during cutting. The suction force of the negative pressure conveying mechanism pulls the film forward, coordinating with the synchronous action of laser cutting to achieve continuous and stable feeding, reducing manual intervention and improving processing efficiency. In addition, negative pressure adsorption can promptly remove heat and debris generated during cutting, reducing the heat-affected zone and protecting the integrity of the film edge.
[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
