[0002] Composite materials have become a trend as materials for aircraft manufacturing due to their advantages such as light weight, high specific strength, high specific modulus, good ductility, strong designability, and corrosion resistance. Among them, the composite material bulkhead is the main supporting structure of the composite material fuselage, and has typical structural characteristics such as multiple corners and curvature in the arc length direction.

[0003] However, during the manufacturing process of the composite material bulkhead, the fiber angle may be deflected during the laying, cutting or preforming of the workpiece, and the deviation of the fiber angle is a key factor affecting the mechanical properties of the part.

[0034] Embodiment One

[0035] Figure 1 A flowchart of a fiber angle determination method of a bulkhead preform according to Embodiment One of the present application is provided, the present embodiment can be applicable to the case of quantitatively detecting the fiber angle of a bulkhead preform, the method can be executed by a fiber angle determination device of a bulkhead preform, the fiber angle determination device of a bulkhead preform can be realized in the form of hardware and / or software, and the fiber angle determination device of a bulkhead preform can be configured in an electronic device. As shown in the figure, the method comprises: Figure 1

[0036] S110, based on the target detection observation area in the target detection template, acquiring a laying image corresponding to the target bulkhead preform, and determining a current fiber line corresponding to the target bulkhead preform in the laying image; wherein the target detection observation area in the target detection template comprises a target detection area angle category and a corresponding target angle approval line. ​

[0037] The target detection template can refer to a pre-generated standard detection template. Generally, the target detection template includes a plurality of hollow regions to observe the fiber angle of the spacer preform through the hollow regions, and to provide an effective basis for subsequent detection of the fiber angle deviation value of the spacer preform.

[0038] The detection observation area can refer to a hollow region in the target detection template for observing the fiber angle of the spacer preform. The target detection observation area can refer to a detection observation area selected for determining the fiber angle in the target detection template. The target detection area angle category can refer to the detection angle category corresponding to the target detection observation area. For example, the target detection area angle category can include 0°, ±45°, and 90°. The target angle reference line can refer to a standard line for angle verification in the target detection observation area. For example, it can be the boundary line of the target detection observation area.

[0039] The target spacer preform can refer to a spacer preform for which the fiber angle deviation value needs to be determined. The ply image can refer to the fiber image of the target spacer preform within the target detection observation area. The current fiber line drawing can refer to the fiber angle line drawing in the ply image.

[0040] In an optional embodiment, the present application embodiment can further include: determining a template schematic diagram corresponding to the target detection template based on the angle reference line and the basic spacer web detection area; and cutting the basic spacer web based on the template schematic diagram by a cutting machine to generate the target detection template.

[0041] The basic spacer web can refer to an original spacer web without cutting processing. The angle reference line can refer to the center line of the basic spacer web, i.e., the 0° reference line of the basic spacer web. The basic spacer web detection area can refer to an area for detecting the fiber angle of the spacer preform. Generally, the basic spacer web detection area can include a 0° detection area, a ±45° detection area, and a 90° detection area. It is worth noting that the number of basic spacer web detection areas and the arrangement order of each angle detection area can be set according to actual application requirements, and the present application embodiment does not limit this.

[0042] The template schematic diagram can refer to a schematic diagram obtained by arranging and drawing each basic spacer web detection area according to actual application requirements and the angle reference line. Figure 2A target detection sample principle diagram provided by an embodiment of the present application is shown. Specifically, the sample principle diagram includes an angle reference line (i.e., a 0° reference line), each basic partition frame web detection area, and a 90° reference line in each basic partition frame web detection area. The 0° detection area and the 90° detection area use rectangular marks, and the ±45° detection area uses a triangular mark. The material machine can refer to a device for locally cutting and hollowing the basic partition frame web. For example, if the basic partition frame web detection area is a 0° detection area or a 90° detection area, the rectangular area is hollowed and cut, and if the basic partition frame web detection area is a ±45° detection area, the triangular area is hollowed and cut. Thus, the target detection observation area in the target detection sample and the corresponding target angle reference line are obtained.

[0043] S120, determining a deflection distance between the target detection sample and the current fiber line based on the target angle reference line in the target detection observation area.

[0044] The deflection distance can refer to the vertical and horizontal deviation distances between the current fiber line of the target partition frame preform and the target angle reference line.

[0045] Specifically, since the target detection observation area is a hollowed area, when measuring the current fiber line through the target detection observation area, the target angle reference line in the target detection observation area can be used as a reference standard, and thus the deflection distance between the target detection sample and the current fiber line is determined, providing an effective basis for subsequent operations.

[0046] S130, determining an actual fiber deflection angle corresponding to the target partition frame preform based on the target detection area angle category corresponding to the current fiber line and the deflection distance.

[0047] The actual fiber deflection angle can refer to the angle deviation value of the ply fiber of the target partition frame preform in the actual processing process.

[0048] Specifically, the actual fiber deflection angle corresponding to the target partition frame preform can be calculated based on the target detection area angle category corresponding to the current fiber line and the deflection distance between the current fiber line and the target angle reference line.

[0049] The technical scheme of the embodiment of the present application obtains the ply image corresponding to the target frame preform in the target detection observation area in the target detection template, determines the current fiber line corresponding to the target frame preform in the ply image, then determines the deflection distance between the target detection template and the current fiber line based on the target angle reference line in the target detection observation area, and finally determines the actual fiber deflection angle corresponding to the target frame preform based on the target detection area angle category corresponding to the current fiber line and the deflection distance, thereby solving the problem of low detection efficiency and accuracy of the fiber angle of the frame preform, achieving detection of the fiber angle of the frame preform, and improving the detection efficiency and accuracy of the fiber angle of the frame preform.

The second embodiment is based on the above-mentioned embodiment and is refined. In the second embodiment, the operation of obtaining the ply image corresponding to the target frame preform based on the target detection observation area in the target detection template is refined. Specifically, the operation can include: determining the target detection observation area in the target detection template based on the first positioning mark corresponding to the target detection template and the second positioning mark corresponding to the target frame preform; and obtaining the ply image corresponding to the target frame preform by identifying the target frame preform based on the target detection observation area image. As shown in the figure, the method includes: Figure 3

[0052] S210, during the material layer paving process of the target frame plate, obtaining the material layer image corresponding to the target frame plate.

The visualization area can refer to the area on the target frame flat plate that is subjected to visualization processing. Figure 4 The visualization area provided by the embodiment of the application is shown. Specifically, first, the position distance between the target detection observation area in the target detection template and the template end in the layer image is determined according to the target detection area angle category of the target detection observation area in the target detection template, wherein the position distance between the template end and the ±45° target detection observation area and the position distance between the template end and the 90° target detection observation area can be inconsistent. Further, the visualization area corresponding to the layer image is determined according to the position distance between the target detection observation area in the target detection template and the template end in the layer image. Finally, the target recognition processes the base fiber angle in the visualization area of the target frame flat plate, and visualizes the base fiber angle to generate the target frame flat plate containing the base fiber angle, so that the base fiber angle after visualization processing can appear in the target detection observation area in the target detection template, facilitating the smooth progress of subsequent operations. It is worth noting that the angle reference line (i.e. 0° reference line) can also be visualized to the visualization area.

[0058] S230, preforming the target frame flat plate by a frame preforming device to generate a target frame preform.

[0059] Wherein, the frame preforming device can refer to a device that performs preforming operations such as bending and roll bending on the target frame flat plate.

[0062] It is worth noting that the first positioning mark corresponding to the target detection template and the second positioning mark corresponding to the target frame preform need to be set according to the same positioning standard.

[0063] Specifically, after the target detection template and the target frame preform are positioned according to the first positioning mark and the second positioning mark, the detection observation area of the fiber line of the target frame preform observed on the target detection template can be taken as a target detection observation area.

[0064] S250, processing the target frame preform based on the target detection observation area image to obtain a ply image corresponding to the target frame preform.

[0068] Wherein, the measurement instruction can refer to an instruction indicating the measurement of the deflection distance. Generally, the measurement instruction includes a first position corresponding to the current fiber line and a second position corresponding to a target angle approval line in the target detection observation area. The first position can refer to the position of the current fiber line on the target frame preform. The second position can refer to the position of the target angle approval line in the target detection observation area. The user terminal can refer to a terminal that receives the measurement instruction and measures the deflection distance according to the measurement instruction.

[0069] S280, determining the deflection distance between the target detection template and the current fiber line based on the first position and the second position through the user terminal.

[0072] The target conversion method may refer to an angle conversion method corresponding to the target detection area angle category. For example, if the target detection area angle category is 0°, the target conversion method may be a 0° conversion method. If the target detection area angle category is ±45° or 90°, the target conversion method may be a ±45° or 90° conversion method.

[0073] Figure 5 The figure shows a schematic diagram of a 0° conversion method provided by an embodiment of the present invention. In which, a and c can be the distance between any two points on the 0° verification line (i.e., the target angle verification line) perpendicular to the current fiber drawing line. b can be the horizontal distance between any two points on a and c. θ can represent the angular deviation value of the current fiber drawing line relative to the 0° verification line, that is, the actual fiber deflection angle corresponding to the target bulkhead preform.

Specifically, the conversion formula for ±45° and 90° is: tanθ = a / b, i.e., θ = arctana / b.

[0076] It is worth noting that if the ply image contains multiple different plies, the current fiber lines in each ply can be obtained by peeling off layer by layer and performing subsequent operations.

[0077] S2100. Determine an actual fiber deflection angle corresponding to a target bulkhead preform based on the target conversion method and the deflection distance.

[0078] Specifically, after determining the target conversion method corresponding to the current fiber drawing line, the deflection distance between the target detection template and the current fiber drawing line can be substituted into the calculation formula of the target conversion method, thereby determining the actual fiber deflection angle corresponding to the target bulkhead preform.

[0079] The technical scheme of the embodiment of the present application obtains the basic fiber angle corresponding to the material layer image of the target frame panel obtained in the material layer paving process of the target frame panel through target recognition processing, and visualizes the basic fiber angle to generate a target frame panel containing the basic fiber angle. Then, the target frame panel is preformed by a frame preforming device to generate a target frame preform. The target detection observation area in the target detection sample is determined based on the first positioning mark corresponding to the target detection sample and the second positioning mark corresponding to the target frame preform. The target frame preform is identified based on the target detection observation area image to obtain the paving layer image corresponding to the target frame preform.

Further, the measurement instruction is generated based on the current fiber line, and the measurement instruction is sent to the user end. The deflection distance between the target detection sample and the current fiber line is determined by the user end based on the first position and the second position. Finally, the target conversion method corresponding to the current fiber line is determined based on the target detection area angle category corresponding to the current fiber line, and the actual fiber deflection angle corresponding to the target frame preform is determined based on the target conversion method and the deflection distance. The problem of low detection efficiency and accuracy of the fiber angle of the frame preform is solved. The detection of the fiber angle of the frame preform is realized, and the detection efficiency and accuracy of the fiber angle of the frame preform are improved.
