Description

Technical Field

[0001] This invention belongs to the field of composite material processing equipment, and particularly relates to a material pressing roller device and control method adapted to a fully automatic composite material tape laying equipment. Background Technology

[0002] Composite material parts manufacturing involves a process of layering prepreg tapes, compacting them, and then curing them. The laying and compaction of the prepreg tapes are crucial steps in composite material parts manufacturing. Through this process, gases generated during the prepreg tape laying are effectively expelled, resulting in a tighter bond between layers and ensuring the overall quality of the composite material parts.

[0003] In the prepreg compaction molding process, the magnitude of the compressive force generated must be reasonably appropriate to the material properties to avoid surface damage.

[0004] The existing tape laying machine's tape laying head compaction device does not have a significant compaction effect on curved surfaces, thus affecting the tape laying efficiency and accuracy.

[0005] Currently, the compaction operation after the tape laying machine has finished laying is mostly done manually, which is labor-intensive and difficult to meet the needs of large-scale production. Furthermore, the pressure applied by the operator can lead to uneven compaction, thus affecting the laying quality.

[0006] Patent document CN118477931A discloses a pretreatment device for processing metal composite materials. A support conveying platform (2) is fixedly connected to the upper surface of the base plate (1). An mounting plate (3) is fixedly connected to the upper surface of the base plate (1). A pair of mounting plates (3) are rotatably connected to the same second feeding clamp shaft (9). One end of the second feeding clamp shaft (9) passes through the front of the front mounting plate (3). A pair of mounting plates (3) are rotatably connected to the same first feeding clamp shaft (6). A feeding tray (4) is fixedly connected to the upper surface of the base plate (1). A cutting tool (5) is installed above the feeding tray (4). An intermittent feeding mechanism (7) is fixedly connected to the inner wall of the mounting plate (3). A screening component (8) is fixedly connected to the right side of the feeding tray (4).

[0007] Patent document CN118404837A discloses a device and control method for precisely controlling the layup angle of composite materials. The device includes a cutting part and an angle control console. The cutting part is vertically mounted above the angle control console. The angle control console includes a console housing, a rotary table, and a control mechanism. The rotary table is rotatably mounted and has a 0° mark. The control mechanism includes a rotation control part and a transfer control part. By operating the rotation control part, the rotary table can be adjusted to a fixed angle. By operating the transfer control part, the composite prepreg can be transferred. Summary of the Invention

[0008] The purpose of this invention is to provide a material pressing roller device and control method adapted to fully automatic composite material tape laying equipment. This device can effectively solve the technical problems of accurate compaction and accurate laying of prepreg.

[0009] To achieve the first objective of this invention, the following technical solution is provided: A tape pressure roller device adapted to a fully automated tape laying equipment for composite materials includes a pair of pressure roller mounting seats and a pressure shoe assembly disposed between the two pressure roller mounting seats; Each pressure roller mounting base is provided with a first pressure rod with one end fixed and swinging, a second pressure rod hinged to the swinging end of the first pressure rod, a first telescopic assembly for pushing the first pressure rod to swing, and a second telescopic assembly for pushing the second pressure rod; The extended end of the first telescopic component is hinged to the swing end of the first pressure rod, and the fixed end of the first telescopic component is hinged to the pressure roller mounting seat. The extended end of the second telescopic component is hinged to the end of the second pressure rod away from the first pressure rod, and the fixed end of the second telescopic component is coaxially hinged to the first pressure rod on the pressure roller mounting seat; A pressure roller is provided between the second pressure rods on the two pressure roller mounting seats, which spans the material placement plate.

[0010] Specifically, the two pressure roller mounting seats are provided with limiting grooves on opposite sides for lifting and lowering the pressure shoe assembly.

[0011] Specifically, the first telescopic component and the second telescopic component are driven by cylinders to reciprocate at their extended ends.

[0015] To achieve the second objective of this invention, the following technical solution is provided: A control method for the aforementioned tape pressure roller device adapted to a fully automated composite material tape laying equipment includes the following steps: The strip is laid on the strip placement plate, and the first pressure bar is pushed to swing by the first telescopic component, so that the pressure roller swings to above the strip; The second telescopic component pushes the second pressure bar, causing the pressure roller to squeeze the material until the preset pressure is met; When the continuous laying of the strip begins, the second telescopic component is controlled to retract, causing the pressure roller to leave the strip.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] like Figure 1 and 2 As shown, this embodiment provides a fully automated composite material tape laying device equipped with a tape pressure roller. Figure 1 The device includes a compaction support assembly 1 for fixing the equipment and a material placement plate 5, and a material pressure roller device is provided on the compaction support assembly 1. The material pressure roller device includes a pressure roller assembly 3 and a pressure shoe assembly 2.

[0021] like Figure 2 As shown, the pressure roller assembly 3 includes a first telescopic assembly 31, a pressure roller support rotary shaft 32, a first pressure roller rod 33, a second telescopic assembly 34, a second pressure roller rod 35, a pressure roller wheel 36, and a pressure roller mounting base 37.

[0022] More specifically, the tail end of the first telescopic component 31 is mounted on the pressure shoe guide rail mounting seat, the beginning end of the first telescopic component 31 is hinged to one end of the first pressure roller rod 33 to form a swing joint, the pressure roller support rotary shaft 32 and the first pressure roller rod 33 are hinged to form a rotary joint, the pressure roller support rotary shaft 32 and one end of the second pressure roller rod 35 are hinged to form a rotary joint, the other end of the first telescopic component 31 is hinged to the tail end of the second telescopic component 34 to form a rotary joint, and the beginning end of the second telescopic component 34, the other end of the second pressure roller rod 35 and the pressure roller wheel 36 form a composite hinge.

[0023] like Figure 4 As shown, the pressure roller lays and compacts the material: the first telescopic component 31 extends, driving the first telescopic component 31 to rotate relative to the pressure roller support rotary shaft 32. When the first telescopic component 31 swings to the preset position, the first telescopic component 31 is fixed. At this time, the second telescopic component 34 begins to extend, thereby driving the pressure roller 36 to adjust its position, so that the pressure roller 36 can fully contact and compact the material surface.

[0024] The pressure roller 36 is externally wrapped with a layer of rubber. The deformation characteristics of rubber under stress make this pressure roller device suitable for compacting irregular curved surfaces on the laying fixture. Another main function of the pressure roller device is to separate the tail material of the material strip laid on the fixture from the backing paper. This tail material must remain on the backing paper during the cutting process due to its shape (angle). The pressure roller device is available in 150mm and 300mm widths, respectively suitable for 150mm and 300mm wide strips. When the width is 150mm, the slope ≥ 1:5, and the slope height can reach 6mm; when the width is 300mm, the slope ≥ 1:10, and the slope height can reach 6mm. The maximum pressure of the laying head pressure roller is ≥1000N (or 0.8 MPa; if a pressure unit is selected, an equivalent calculation formula must be provided), and the pressure is programmable, adjustable, and displayable.

[0025] This embodiment also provides a control method for using a material roller device provided in the above embodiment, the specific process of which is as follows: like Figure 5 As shown, the complete pressure shoe assembly is driven to descend under the drive of the cylinder, so that its pressure shoe piece is in full contact with the surface of the workpiece, and the pressure roller device is in the pressure shoe and pressure roller switching state; like Figure 6 As shown, after the pressure shoe assembly 2 makes full contact with the workpiece, the first telescopic assembly 31 of the pressure roller device retracts, driving the first pressure roller rod 33 to rotate relative to the pressure roller 36. When the first pressure roller rod 33 swings to the preset position, the first pressure roller rod 33 remains fixed. At this time, the second telescopic assembly 34 begins to retract, thereby driving the second pressure roller rod 35 to rotate, and then driving the pressure roller support rotation shaft 32 to rise away from the workpiece surface.

[0026] The device provided in this embodiment uses a pressure roller device for pressing. The entire pressure roller device is equipped with a guide rail in the Z-axis direction, which can adaptively adapt to changes in the surface curve and ensure that the pressing force is stable within the corresponding range of the programmed value. This enables the precise laying of the strip onto flat or gently curved parts with large surface areas, such as wall panels and skins.

[0027] Furthermore, the terms "upper," "lower," "inner," "outer," "front," and "rear" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Unless otherwise specifically stated, the relative steps, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0028] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present invention should be included in the scope of the claims of the present invention.

[0029] Finally, it should be noted that the above-described embodiments are merely specific implementations of the present invention, used to illustrate the technical solutions of the present invention, and not to limit it. The scope of protection of the present invention is not limited thereto. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments within the technical scope disclosed in the present invention, or make equivalent substitutions for some of the technical features; and these modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be covered within the scope of protection of the present invention.
