Description

Technical Field

[0001] This invention relates to the field of paper-cutting forming technology, specifically a dynamic paper-cutting linkage forming method. Background Technology

[0002] Paper cutting, as an important application combining traditional handicrafts and modern forming technology, has wide demand in decoration, cultural products, and industrial design. Existing paper cutting methods are mostly static processing methods, that is, completing a single cut, fold, or press shape through preset fixed parameters, which has many technical shortcomings:

[0003] 1. The forming process lacks dynamic adjustment capabilities and can only execute a single action sequence according to a preset program. It cannot adapt to the multi-level structural requirements of complex patterns. For three-dimensional paper cutting or composite pattern paper cutting that requires multiple steps, the forming effect is rough and the layers are blurred.

[0004] 2. Each molding process is independent of the others. There is no linkage mechanism for actions such as cutting, folding, and pressing. Errors in the previous process cannot be corrected by the subsequent process, resulting in low overall molding accuracy and problems such as pattern misalignment and edge damage.

[0005] 3. The molding parameters are set in a fixed manner, without taking into account the differences in toughness, thickness and ductility of different materials. It is impossible to adjust the processing force, angle and other key parameters according to the real-time feedback of the material. The adaptability is poor, which can easily lead to material waste or substandard molding.

[0006] 4. The lack of a dynamic verification mechanism during the molding process, with quality inspection only conducted after final molding, makes it impossible to detect deviations in intermediate processes in a timely manner, resulting in high rework rates and low production efficiency. Summary of the Invention

[0007] The purpose of this invention is to provide a dynamic paper-cutting linkage forming method, which aims to solve the problems of lack of linkage, poor adaptability and low precision in the existing paper-cutting forming technology, and to achieve efficient and accurate forming of complex patterns and multiple materials.

[0008] To solve the above technical problems, the present invention provides a dynamic paper-cutting linkage forming method, comprising the following steps:

[0009] (1) Pre-treatment and initialization of linkage parameters before molding:

[0010] 1.1 Perform hierarchical analysis on the pattern data of the target paper-cutting, divide it into basic pattern layer, refined pattern layer and decorative pattern layer, and determine the forming priority and process relationship of each layer;

[0011] 1.2 Perform property testing on the molded material to obtain data on its toughness, thickness, and ductility, and establish a material property database;

[0012] 1.3 Based on the pattern layer analysis results and material property data, initialize the basic parameters of each process, including cutting, folding, pressing, and shaping, and set the linkage trigger conditions and feedback thresholds for each process.

[0013] (2) Basic forming linkage execution:

[0014] 2.1 Based on the initialization parameters, the cutting process of the basic pattern layer is started, and cutting trajectory data and material stress feedback data are collected in real time during the cutting process;

[0015] 2.2 When the cutting process meets the linkage triggering conditions, the folding process is automatically started. The folding angle and speed are dynamically adjusted according to the cutting trajectory data to ensure that the folding edge is accurately aligned with the cutting pattern.

[0016] 2.3 During the folding process, the force data at the folding point of the material is collected by a pressure sensor. If the force data exceeds the feedback threshold, the folding speed and force are adjusted in real time and fed back to the cutting process to correct the compensation amount of the subsequent cutting path.

[0017] (3) Hierarchical refinement and linkage molding:

[0018] 3.1 After the basic pattern layer is formed, the basic forming effect data is collected through the visual inspection module and compared with the preset standard data to determine the forming deviation compensation parameters of the refined pattern layer;

[0019] 3.2 Based on the deviation compensation parameters, the cutting parameters of the refined pattern layer are dynamically adjusted, the refined cutting process is started, and the pressing process is linked at the same time to press the local pattern after cutting at a fixed point to enhance the three-dimensionality of the pattern.

[0020] 3.3 The pressure parameters of the pressing process are dynamically adjusted based on the material property database and real-time force feedback to avoid material damage or excessively deep pressing marks. At the same time, the pressing data is fed back to the fine cutting process to achieve closed-loop linkage between the two.

[0021] (4) Cross-process joint verification and correction:

[0022] 4.1 After each layer is formed, cross-process verification is initiated. The forming dimensions, pattern accuracy, and material integrity data of the current layer are collected through the visual inspection module and the force feedback module.

[0023] 4.2 The collected data is compared with the molding data of the previous level and the preset standard data. If the deviation exceeds the allowable range, a correction instruction is automatically generated to adjust the molding parameters of the next level, and at the same time, the cumulative deviation of the previous process is corrected.

[0024] 4.3 During the formation of the decorative pattern layer, the forming data of the basic pattern layer and the refined pattern layer are linked to ensure the positional accuracy and stylistic consistency of the decorative pattern with the basic pattern and the refined pattern.

[0025] (5) Dynamic finalization and final verification:

[0026] 5.1 After all layers of molding are completed, the dynamic shaping process is started. According to the material properties and pattern structure, gradient temperature and pressure are used for shaping. The shaping parameters are dynamically optimized based on the molding data throughout the process.

[0027] 5.2 After the final shaping is completed, a final verification is performed, and data on the overall size, pattern accuracy, three-dimensionality, and material integrity of the paper-cut are collected. If the preset standards are met, the shaping is completed; if not, the corresponding process correction is triggered according to the deviation type, and the related dynamic shaping steps are re-executed.

[0028] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this invention are:

[0029] 1. This invention proposes a hierarchical linkage forming logic, which divides paper-cutting forming into a multi-level structure. Through parameter feedback and process linkage between each level, it solves the problems of fuzzy and misaligned levels in traditional static forming, and achieves precise layered forming of complex patterns.

[0030] 2. This invention constructs a closed-loop linkage mechanism for the entire process of "cutting-folding-pressing-shaping". Each process is no longer executed independently, but the parameters are dynamically adjusted through real-time data feedback to form a linkage relationship of mutual compensation and mutual correction, which greatly reduces the cumulative error.

[0031] 3. This invention introduces a material property adaptive adjustment module, which dynamically optimizes key parameters of each process based on material testing data and real-time stress feedback. This breaks through the limitations of traditional fixed parameter molding, adapts to materials with different toughness and thickness, reduces the breakage rate, and establishes a cross-process linkage verification mechanism. After each layer of molding, data verification and deviation correction are performed. This not only corrects the deviation of the current layer, but also backtracks to compensate for the cumulative error of the previous process, improving the overall molding accuracy and stability.

[0037] This invention provides a dynamic paper-cutting linkage forming method.

[0038] Example 1: Multi-layer three-dimensional paper cutting

[0039] Pre-treatment and initialization of linkage parameters before molding:

[0040] The pattern data of the target multi-layer three-dimensional paper cutting is analyzed, and the bottom basic pattern layer (petal outline), the middle refined pattern layer (petal texture), and the top decorative pattern layer (stamen details) are divided. The bottom layer is determined to have the highest priority, followed by the top layer.

[0041] The selected red Xuan paper was subjected to property testing to obtain its toughness, thickness, and ductility data, which were then entered into the material property database.

[0042] Initialize the underlying cutting parameters (cutting speed, blade pressure) and folding parameters (folding angle, speed). Set the folding process to be triggered when the cutting completion reaches 90%. Set the folding force feedback threshold to 70% of the material's maximum bearing capacity.

[0043] Basic molding linkage execution:

[0044] The bottom-level cutting process is initiated, and the petal outline is cut according to the preset path using laser cutting. The coordinate data of the cutting trajectory and the material stress data are collected in real time.

[0045] When the cutting completion reaches 90%, the folding process is automatically triggered. Based on the coordinate data of the cutting trajectory, the edge of the petal outline is folded inward by 30°. The initial folding speed is set to 5mm / s. During the process, the pressure sensor detects that the force at the folding point is close to the feedback threshold, and the folding speed is automatically adjusted to 3mm / s. At the same time, the feedback is sent to the cutting process to compensate and correct the edge path of the subsequent uncut petals by 0.1mm.

[0046] After folding, the force data collected by the pressure sensor stabilizes within the feedback threshold range, and the basic pattern layer is formed.

[0047] Hierarchical refinement and linkage molding:

[0048] The visual inspection module collects the folding alignment accuracy data of the bottom petals and finds a folding edge line that deviates from the cutting contour by 0.2mm, generating deviation compensation parameters.

[0049] Based on the deviation compensation parameters, the path of the middle layer refinement cutting is shifted by 0.2mm in the deviation direction, and the laser refinement cutting is started to cut the petal texture. At the same time, the pressing process is linked, and a micro pressing head is used to press the texture edge at a fixed point. The initial pressing pressure is set to 0.3N.

[0050] During the pressing process, the force feedback module detects that the pressing force in a certain area is too large, and adjusts the pressing pressure to 0.2N in real time. At the same time, it feeds back to the fine cutting process to reduce the cutting depth in that area and avoid material damage.

[0051] Cross-process joint verification and correction:

[0052] After the middle layer is formed, cross-process verification found that the position of the middle layer texture and the bottom petals is 0.15mm off. A correction instruction was generated to shift the cutting position of the flower stamen of the top decorative pattern layer by 0.15mm in the direction of the deviation.

[0053] At the same time, the compensation amount of the bottom layer fold was corrected by retrospectively adjusting the bottom layer fold angle of subsequent batches by 0.5° to avoid the accumulation of deviations;

[0054] During the cutting of the top stamen, the folding position data of the bottom petals and the distribution data of the middle texture are linked to ensure that the stamen is located in the center of the petals and that the style is consistent with the petal texture.

[0055] Dynamic finalization and final verification:

[0056] After all layers are formed, a dynamic setting process is initiated, using a temperature gradient of 30°C to 50°C and a pressure gradient of 0.2N to 0.4N for setting. The setting time is dynamically adjusted to 3 minutes based on the material thickness.

[0057] Finally, the data on the size deviation, texture accuracy, and three-dimensionality of the collected paper-cut petals were verified and found to meet the preset standards, thus completing the shaping process.

[0058] Example 2: Multi-layer three-dimensional paper cutting (Xuan paper material, suitable for decorative ornaments)

[0059] 1. Pre-treatment and initialization of linkage parameters before molding

[0060] The pattern data of the target "three-layer peony three-dimensional paper cutting" is analyzed hierarchically: the bottom layer is divided into basic pattern layer (peony petal outline, priority 1), the middle layer is refined pattern layer (petal vein texture, priority 2), and the top layer is decorative pattern layer (stamen and dew details, priority 3). It is clear that the bottom layer is the benchmark for subsequent layers, the middle layer needs to be precisely aligned with the bottom layer petal outline, and the top layer needs to be adapted to the middle layer vein distribution.

[0061] The selected 70g red Xuan paper was subjected to property testing: the thickness was obtained by a thickness sensor (0.1mm), the toughness parameter was obtained by tensile testing, and the ductility data was obtained by ductility testing. The above data were entered into the material property database.

[0062] Initialize the basic parameters for each process:

[0063] Cutting process: laser cutting speed 5mm / s, blade pressure 0.1N, cutting depth 0.1mm;

[0064] Folding process: Basic folding angle 30°, initial folding speed 5mm / s;

[0065] Linkage trigger condition: The folding process is automatically started when the cutting completion rate reaches 90%;

[0066] Feedback threshold: The folding force shall not exceed 70% of the maximum bearing capacity of Xuan paper (set to 0.07N after testing).

[0067] 2. Basic forming linkage execution

[0068] Start cutting the underlying basic pattern layer: The laser cutting head cuts the outline of the peony petals according to the preset path, and collects the coordinate data of the cutting trajectory in real time through the vision sensor and the force data of the material cutting point through the pressure sensor (real-time feedback range 0.08~0.1N).

[0069] Linkage-triggered folding process: When the cutting completion reaches 90% (i.e., the outline of the last petal is 10% uncut), the PLC automatically triggers the folding process. Based on the coordinate data of the cutting trajectory, the PLC controls the folding mechanism to fold the edges of each petal towards the center by 30°, with an initial folding speed of 5mm / s.

[0070] Dynamic adjustment and feedback correction: During the folding process, the pressure sensor detects that the force at the folding point of a petal reaches 0.07N (feedback threshold), and immediately adjusts the folding speed to 3mm / s. At the same time, it feeds back the deviation signal to the cutting process. The cutting head compensates and corrects the edge path of the remaining uncut petals by 0.1mm to ensure that the folding edge line is completely aligned with the cutting contour.

[0071] The basic pattern layer is formed: the folding force is stable within the range of 0.05~0.06N, and visual inspection shows that the alignment accuracy of the petal outline folding is ≤0.05mm.

[0072] 3. Hierarchical Refinement and Linked Forming

[0073] Deviation compensation parameter determination: The visual inspection module collects the folding alignment data of the bottom petals and finds that the folding edge of a petal deviates from the preset standard by 0.2mm, and generates deviation compensation parameters (0.2mm offset in the deviation direction).

[0074] Refined cutting and pressing linkage: Based on the compensation parameters, the vein path of the middle layer refined cutting is shifted 0.2mm in the deviation direction, and the laser refined cutting is started (the cutting speed is adjusted to 3mm / s and the blade pressure is 0.08N). At the same time, the micro pressing mechanism is linked to press the edge of the cut vein at a fixed point. The initial pressing pressure is 0.3N and the pressing time is 0.5s.

[0075] Closed-loop linkage adjustment: During the pressing process, the force feedback module detects that the pressing force in a certain area reaches 0.35N (exceeding the material's compatibility range), and adjusts the pressing pressure to 0.2N in real time. At the same time, it feeds back to the fine cutting process to reduce the cutting depth of that area to 0.08mm to avoid damage to the Xuan paper. After pressing, the texture of the grain is obvious and there are no excessively deep pressing marks or material damage.

[0076] 4. Cross-process joint verification and correction

[0077] Mid-layer molding verification: The cross-process verification module collected the positional accuracy data of the mid-layer veins and found that the positional deviation between the mid-layer veins and the bottom petals was 0.15mm, which exceeded the allowable range (≤0.1mm).

[0078] Deviation correction and backtracking compensation: Automatically generate correction instructions to shift the stamen cutting position of the top decorative pattern layer by 0.15mm in the deviation direction; at the same time, backtrack and correct the bottom layer folding parameters to finely adjust the bottom layer folding angle of subsequent batches by 0.5° to avoid deviation accumulation.

[0079] Top-layer linkage molding: During the cutting of the top-layer flower stamen and dewdrop, the data on the folding position of the bottom-layer petals and the distribution data of the middle-layer veins are linked to control the cutting head to accurately position the flower stamen in the center of the petals. The details of the dewdrop correspond to the vein nodes, and the positional accuracy deviation is ≤0.05mm.

[0080] 5. Dynamic finalization and final verification

[0081] Dynamic shaping: After all layers are formed, the dynamic shaping process is started. According to the characteristics of Xuan paper (high temperature resistance ≤80℃), the shaping process is carried out by using a gradient temperature of 30℃→40℃→50℃ and a gradient pressure of 0.2N→0.3N→0.2N. The shaping time is dynamically adjusted to 3 minutes according to the material thickness.

[0082] Final verification: Collect the overall dimensions of the paper-cut (diameter 100mm, deviation ≤0.2mm), pattern accuracy (clear veins, centered flower stamen), three-dimensionality (distinct petal layers, no collapse), and material integrity (no damage, no scorch marks). All data meet the preset standards, and the paper-cut is completed.

[0083] Example 3: Composite material paper cutting molding (non-woven fabric + metal foil, suitable for cultural and creative pendants)

[0084] 1. Pre-treatment and initialization of linkage parameters before molding

[0085] Pattern layer analysis: The target "composite material zodiac paper-cut" (bottom non-woven fabric + top metal foil) is divided into layers: bottom basic pattern layer (zodiac outline, non-woven fabric material, priority 1) and top decorative pattern layer (zodiac hair and patterns, metal foil material, priority 2). It is clear that the top layer must be completely attached to the bottom outline, and the metal foil pattern must not exceed the boundary of the non-woven fabric.

[0086] Material property testing: The key physical properties of nonwoven fabric (thickness 0.3mm, high toughness, moderate ductility) and metal foil (thickness 0.05mm, low toughness, good ductility) were tested separately to establish a dual material property database.

[0087] Initialization parameter settings:

[0088] Cutting process: Non-woven fabric cutting speed 3mm / s, blade pressure 0.2N; Metal foil cutting speed 2mm / s, blade pressure 0.05N;

[0089] Folding process: The non-woven fabric base is folded at an angle of 45° and the folding speed is 4mm / s;

[0090] Pressing process: The pressing pressure of the metal foil is 0.1N, and the pressing time is 0.3s;

[0091] Linkage trigger condition: The folding process is started immediately after the bottom layer cutting is completed;

[0092] Feedback thresholds: non-woven fabric folding force ≤ 0.25N, metal foil pressing force ≤ 0.12N.

[0093] 2. Basic forming linkage execution

[0094] Cutting of the bottom non-woven fabric: The cutting mechanism cuts the non-woven fabric according to the outline of the zodiac animal, and collects cutting trajectory data and force data (0.18~0.2N) in real time. When the cutting is 100% complete, the folding process is triggered immediately.

[0095] Folding linkage adjustment: Based on the cutting trajectory data, the folding mechanism folds the edge of the non-woven zodiac outline by 45°. The initial folding speed is 4mm / s. The pressure sensor detects that the folding force is stable at 0.2~0.22N (not exceeding the feedback threshold). No speed adjustment is required. After folding, the outline alignment accuracy deviation is ≤0.1mm.

[0096] 3. Hierarchical Refinement and Linked Forming

[0097] Bottom layer molding effect verification: Visual inspection shows that the non-woven zodiac outline size deviation is ≤0.1mm, with no damage or rough edges, and it can directly proceed to the top layer metal foil decoration molding.

[0098] Decorative cutting and pressing linkage: Based on the coordinate data of the bottom contour, the cutting of the metal foil decorative pattern is started (cutting speed 2mm / s, blade pressure 0.05N), and at the same time, the pressing mechanism is linked to press the cut hair pattern at a fixed point, with an initial pressing pressure of 0.1N.

[0099] Material adaptive adjustment: During the pressing process, the force feedback module detects that the pressing force in a certain area of ​​the metal foil reaches 0.12N (feedback threshold), and adjusts the pressing pressure to 0.08N in real time to avoid stretching and deformation of the metal foil; after the cutting and pressing are linked, the metal foil pattern and the non-woven fabric bottom layer are completely aligned, without any lifting or wrinkling.

[0100] 4. Cross-process joint verification and correction

[0101] Cross-layer verification: The position data of the top metal foil pattern was collected, and it was found that the hair pattern exceeded the non-woven fabric boundary by 0.1mm, which is outside the allowable range (≤0.05mm).

[0102] Correction execution: Automatically generate correction instructions to perform secondary cutting of the metal foil pattern in the area (reducing the cutting range by 0.1mm), and simultaneously feed back to the bottom folding process to finely adjust the folding angle of the corresponding area by 0.3° to ensure that the metal foil pattern in subsequent batches does not exceed the boundary.

[0103] 5. Dynamic finalization and final verification

[0104] Dynamic shaping: Based on the dual material characteristics, a temperature gradient of 25℃→35℃→45℃ and a pressure gradient of 0.1N→0.2N→0.1N are used for shaping, with a shaping time of 4 minutes (adapting to the bonding stability of metal foil and non-woven fabric).

[0105] Final verification: Collect the overall dimensions of the paper-cut (80mm long × 60mm wide, deviation ≤ 0.15mm), pattern accuracy (no deformation of the metal foil pattern, no deviation beyond the boundary), adhesion (the metal foil and non-woven fabric are completely adhered, no lifting), and material integrity (no damage, no cutting marks). If the preset standards are met, the forming is completed. If there is any lifting of the metal foil, the pressing process is triggered for correction, the fixed-point pressing is repeated, and the shaping time is extended by 1 minute.
