Description

Technical Field

[0001] This invention relates to the field of sand painting technology, and in particular to a laser cloisonné sand painting production process. Specifically, it integrates AI-assisted line drawing generation and laser engraving core processes, solving the high threshold of traditional intangible cultural heritage cloisonné sand painting that relies heavily on the creator's "painting skills" and "modeling ability", and promoting the standardization, simplification and popularization of intangible cultural heritage techniques. Background Technology

[0002] Sand painting is a craft that uses sand as the core creative material, combined with carriers and auxiliary tools, to complete an artwork through steps such as outlining, fixing the shape, and filling in colors. It is mainly divided into two categories: dynamic and static. Current sand painting production relies heavily on manual labor, resulting in insufficient precision, low efficiency, and difficulty in achieving standardized production. When mass-producing sand paintings, the quality of finished products is difficult to maintain. In particular, the core process of traditional intangible cultural heritage cloisonné sand painting, "cloisonné outline making," requires creators to manually outline the pattern and attach metal wires. This demands extremely high drawing skills and modeling abilities, with a learning cycle of several months. Furthermore, problems such as outline deviation and irregular lines are prone to errors, resulting in low efficiency and difficulty in standardization. When mass-producing sand paintings, the quality is difficult to guarantee. Additionally, the base material compatibility is limited to specific wooden boards, making it difficult to expand to diverse materials such as acrylic and ceramic boards. This restricts the application of cloisonné sand painting in decorative paintings, ornaments, and cultural and creative products. Summary of the Invention

Existing sand painting production relies heavily on manual labor, which is insufficient in precision and efficiency, makes it difficult to achieve standardized production, and makes it difficult to maintain consistent quality when producing in batches. In particular, the core process of traditional intangible cultural heritage cloisonné sand painting, "cloisonné outline making", requires the creator to manually outline the pattern and attach metal wires, which requires extremely high drawing skills and modeling ability, with a learning cycle of several months. Furthermore, problems such as outline deviation and irregular lines are prone to occur, resulting in errors, low efficiency, difficulty in standardization, and difficulty in ensuring quality when producing in batches are also present.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A laser cloisonné sand painting production process includes the following modules and components, with the core technology revolving around "AI-powered intelligent line drawing generation - laser engraving and grooving - precise cloisonné in the grooves," and supporting modules achieving standardization throughout the entire process: Substrate pretreatment module, AI line drawing intelligent generation and laser engraving positioning module, semi-automatic wire cutting module, standardized sand filling and sealing module, quality inspection and packaging module; The substrate pretreatment module includes: a fully automatic cutting machine, a multi-station grinding production line, a constant temperature drying oven, and a substrate stacking conveyor.

The automatic positioning fixture system adopts a vacuum adsorption type fixture.

[0007] As a further improvement to this technical solution: the real-time depth monitoring unit includes an integrated laser thickness gauge, which calculates the deviation between the actual depth and the preset value using a formula: .

[0010] As a further improvement to this technical solution: the tunnel-type UV curing machine has a wavelength of 365nm, a power of 1000W, and a conveying speed of 1m / min. The adhesive layer is cured for 30 seconds by UV light irradiation, and the curing effect satisfies the formula: .

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention solves the quality fluctuation problem caused by the reliance on manual labor in traditional processes. The substrate pretreatment module eliminates raw material differences from the source through standardized cutting, polishing and drying; the AI ​​line drawing intelligent generation and laser engraving positioning module ensures that the contours of the indentations are regular by means of precise engraving and real-time monitoring; the semi-automatic wire cutting and standardized sand filling module reduces human operation errors through auxiliary equipment and detection devices, and ultimately ensures that different batches of sand paintings maintain uniformity in outline, color and texture, so as to achieve a stable artistic effect without repeated rework.

[0012] 2. This invention simultaneously lowers the threshold for large-scale production, facilitating the commercialization of sand painting. The various modules work together to achieve a streamlined process from substrate processing to finished product packaging, reducing manual intervention and overcoming the inefficiency of traditional processes. The rapid curing and automated testing processes further shorten the production cycle, avoiding the uncertainties of natural curing and manual testing. In addition, the standardized operating procedures reduce the reliance on operator skills, enabling high-quality production even without extensive manual skills, providing strong support for the mass production and market penetration of sand painting.

Detailed Implementation

The invention is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0016] Please see Figures 1-2 In this embodiment of the invention, a laser cloisonné sand painting production process includes the following modules and components: Substrate pretreatment module, AI line drawing intelligent generation and laser engraving positioning module, semi-automatic wire cutting module, standardized sand filling and sealing module, quality inspection and packaging module; The substrate pretreatment module includes: a fully automatic cutting machine, a multi-station polishing production line, a constant temperature drying oven, and a substrate stacking conveyor. AI-powered line art intelligent generation and laser engraving positioning module: AI image generation system, line art extraction algorithm unit, parameter adjustment interface; industrial-grade multi-head CO2 laser engraving machine, automatic positioning fixture system, real-time depth monitoring unit, and batch layout system for engraving software (compatible with importing AI-generated line art); The semi-automatic wire cloisonné module includes: a pre-cut copper wire dispensing unit, an automatic glue dispensing machine, an auxiliary lighting system for the wire cloisonné station, and a visual inspection alarm device; The standardized sand filling and sealing module includes: a zoned standardized colored sand bag distribution rack, a production line vibration leveling device, an automatic UV curing adhesive spraying machine, and a tunnel-type UV curing machine; The quality inspection and packaging module includes: laser thickness gauge, colorimeter, automatic laminating machine, and intelligent packaging line; Detailed explanation of the functions of each module and component: The substrate pretreatment module consists of a fully automatic cutting machine, a multi-station grinding production line, a constant temperature drying oven, and a substrate stacking conveyor. Its core function is to eliminate differences in substrate raw materials (size, flatness, moisture content), providing a uniform and precise substrate for subsequent laser engraving. The fully automatic cutting machine cuts large multi-layered solid wood boards to a standard size of 40cm × 60cm, solving the problem of large dimensional errors in manual cutting. The multi-station grinding production line uses three-stage grinding and a high-pressure air gun to ensure the substrate surface flatness is ≤0.05mm, with no wood chips remaining. The constant temperature drying oven reduces the substrate moisture content to 8%-10%, preventing warping during engraving. The substrate stacking conveyor stores substrates according to a first-in, first-out principle, connecting different processes and reducing manual handling losses. The AI-powered line art intelligent generation and laser engraving positioning module comprises an AI image generation system, a line art extraction algorithm unit, and a parameter adjustment interface; an industrial-grade multi-head CO2 laser engraving machine, an automatic positioning fixture system, a real-time depth monitoring unit, and a batch layout system for engraving software. It is the core technology for mass production, responsible for accurately generating indentation line art in batches. The industrial-grade multi-head CO2 laser engraving machine simultaneously processes four substrates, increasing efficiency by four times; the automatic positioning fixture system fixes the substrates to prevent slippage, ensuring accurate indentation positioning; the real-time depth monitoring unit detects indentation depth, preventing it from being too shallow or too deep; and the batch layout system for engraving software loads line art from multiple substrates with a single click, reducing manual operation. The semi-automatic cloisonné module consists of a pre-cut copper wire dispensing unit, an automatic dispensing machine, an auxiliary lighting system for the cloisonné workstation, and a visual inspection and alarm device. Its function is to balance batch efficiency and cloisonné precision, reducing the skill threshold for manual operation. The pre-cut copper wire dispensing unit pre-matches the copper wire to the pattern, reducing manual cutting time. The automatic dispensing machine precisely controls the amount of glue, preventing overflow or detachment. The auxiliary lighting system improves the operator's field of vision and reduces visual fatigue. The visual inspection and alarm device identifies copper wire deviations, reducing the defect rate. The standardized sand filling and sealing module consists of a zoned standardized colored sand bag distribution rack, a vibratory paving device, an automatic UV curing adhesive spraying machine, and a tunnel-type UV curing machine. Its function is to achieve standardized sand filling (no color mixing, uniform thickness) and rapid sealing curing, improving the consistency of the finished product. The zoned colored sand distribution rack matches colored sand according to numbers to avoid color mixing; the vibratory paving device aligns the colored sand with the copper wire; the UV spraying machine evenly covers the adhesive layer; and the tunnel-type UV curing machine provides rapid curing in 30 seconds, shortening the construction period. The quality inspection and packaging module consists of a laser thickness gauge, a colorimeter, an automatic laminating machine, and an intelligent packaging line. Its function is to screen qualified finished products, ensure undamaged transportation through standardized packaging, and facilitate batch delivery and traceability. The laser thickness gauge detects the thickness of the adhesive layer and rejects unqualified products; the colorimeter ensures that the colored sand in the same batch is consistent in color; the automatic laminating machine prevents scratches on finished products; and the intelligent packaging line integrates packaging, labeling, and warehousing.

[0017] The multi-station grinding production line consists of a three-stage sandpaper unit for 240-grit coarse grinding, 400-grit fine grinding, and 600-grit precision grinding, a high-pressure air gun, and a conveyor line. Detailed explanation of composition and function: AI Image Line Generation: Based on user needs (such as theme, style, size), the AI ​​image generation tool directly outputs the "line outline" required for cloisonné. The line thickness and pattern complexity can be flexibly adjusted to ensure that the outline meets the cloisonné process standards.

[0018] Laser engraving and grooving operation: Import the AI-generated line outline into the laser engraving machine, and select suitable materials such as wood board and acrylic board as the base; the engraving machine engraves grooves on the material surface according to the outline path, with the depth and width matching the diameter of the wire (such as copper wire or aluminum wire), to achieve "precise wire-groove correspondence".

[0019] The three-level sandpaper unit: sanding in stages from 240 grit coarse sanding to 400 grit fine sanding to 600 grit fine sanding, the purpose of which is to gradually eliminate wood grain protrusions and tiny burrs on the substrate surface: 240 grit coarse sanding: quickly removes obvious defects on the substrate surface (such as coarse wood grain, residual bark); 400 grit fine sanding: refines the surface texture and reduces coarse sanding marks; 600 grit fine sanding: makes the substrate surface smooth to the touch, with a flatness of ≤0.05mm, providing a uniform base for laser engraving; High-pressure air gun: Used in conjunction with the polishing process to blow away wood chips from the substrate surface in real time. Its purpose is to prevent wood chips from adhering to the substrate surface or embedding into the subsequent engraving grooves, which would affect the adhesion of the copper wires during the wire cutting process. Conveyor line: Automatically conveys substrates at a speed of 1m / min. Its function is to enable continuous grinding and cleaning operations without manual handling, and to adapt to the rhythm of batch production lines.

[0020] The industrial-grade multi-head CO2 laser engraving machine is equipped with 4 independent engraving heads, supports simultaneous processing of 4 substrates, and has an engraving depth of 0.3mm±0.05mm. The automatic positioning fixture system adopts a vacuum adsorption type fixture. Detailed explanation of equipment parameters and functions: Industrial-grade multi-head CO2 laser engraving machine: Core parameters: Equipped with 4 independent engraving heads, supporting simultaneous processing of 4 substrates, engraving depth 0.3mm±0.05mm; Function: Simultaneous operation of 4 engraving heads: Compared with single-head engraving machines, the efficiency is increased by 4 times, and the engraving time for a single batch (4 substrates) is ≤8 minutes, which is suitable for the rhythm of mass production; Precise engraving depth: The depth of 0.3mm±0.05mm ensures that the copper wire (diameter 0.3mm) is firmly embedded without penetrating the substrate (thickness 1.8cm), avoiding substrate damage; Automatic positioning fixture system: Core design: adopts vacuum adsorption fixture; Function: Fixing substrate: the substrate is firmly fixed to the engraving machine table with an adsorption force of 0.3MPa, preventing the substrate from sliding during the engraving process and causing the indentation to shift (positioning error ≤0.1mm); Rapid calibration: the substrate center is simultaneously aligned with the engraving area during adsorption, eliminating the need for repeated manual adjustments and reducing operation time.

[0021] The real-time depth monitoring unit includes an integrated laser thickness gauge, which calculates the deviation between the actual depth and the preset value using a formula: ; Detailed explanation of the formula and its function: Indentation depth deviation (unit: mm) is a core indicator for judging engraving precision. Real-time monitoring of dent depth (acquired by an integrated laser thickness gauge with an accuracy of 0.01 mm). Preset standard indentation depth (fixed at 0.3mm, matching copper wire diameter); Function: Real-time accuracy assessment: Depth data is collected every 5 seconds and calculated. ,like ≤0.05mm: Deemed acceptable, continue carving; if >0.05mm: The system will automatically stop and alarm, prompting the operator to check the engraving machine power (if the power is insufficient and the depth is too shallow, the power needs to be increased) or the cleanliness of the lens (if there is dust on the lens and the depth is uneven), to ensure that the depth of the indentation engraved in batches is consistent, and to provide an accurate reference for subsequent wire cutting.

[0022] The pre-cut copper wire distribution unit consists of an automatic copper wire cutting machine and a barcode matching system. The auxiliary lighting system for the wire cloisonné station consists of an LED ring light and a 3x magnifying glass. The visual inspection alarm device is equipped with a 20-megapixel industrial camera with a recognition accuracy of 0.2mm. Detailed explanation of components and their functions: Pre-cut copper wire distribution unit: Components: Automatic copper wire cutting machine, barcode matching system; Functions: Automatic copper wire cutting machine: Automatically cuts copper wire segments (straight segments and curved segments) according to the line drawing, with a length error of ±1mm, avoiding length deviations caused by manual cutting; Barcode matching system: After the worker scans the barcode to read the substrate pattern number, the system automatically pops up the corresponding copper wire package (labeled with pattern number and segment number), reducing copper wire mismatch or waste, and reducing the preparation time before wire cutting of a single substrate from 20 minutes to 5 minutes; Auxiliary lighting system for cloisonné workstation: Components: LED ring light and 3x magnifying glass; Functions: LED ring light (color temperature 5500K): Provides uniform light source for the cloisonné area, avoiding copper wire embedding deviation caused by local shadows; 3x magnifying glass: Helps workers observe small indentations (such as curve joints), accurately adjust the position of copper wires, and reduce visual fatigue. Visual inspection alarm device: Core parameters: Equipped with a 20-megapixel industrial camera with a recognition accuracy of 0.2mm; Function: Automatically photographs the substrate after wire cloisonné and compares the actual copper wire position with the standard line drawing through an image comparison algorithm. If the copper wire offset is >0.2mm, an alarm is immediately triggered to prompt manual fine-tuning, reducing the copper wire offset rate in mass production from 5% to 1% and preventing defective products from flowing into subsequent processes.

[0023] The zoned standardized colored sandbag distribution rack categorizes and arranges colored sandbags according to pattern number and area number, and integrates a barcode scanning function. The assembly line vibration leveling device has a vibration frequency of 50Hz, a duration of 3 seconds, and an amplitude of ≤1mm. Detailed explanation of components and their functions: Standardized Colored Sandbag Distribution Rack: Core Design: Colored sandbags are categorized and arranged according to pattern number and area number (e.g., Pattern A, Area 1, Red; Pattern A, Area 2, Gold), with integrated barcode scanning and identification function; Functions: Categorized Placement: Each bag of colored sand precisely matches a filling area on the base plate, with a weight error of ±0.5g, avoiding color mixing problems during manual color separation (color mixing rate reduced from 8% to 0); Barcode Scanning and Identification: Workers can obtain the corresponding colored sand area by scanning the barcode, without the need for memorization or searching, improving sand filling efficiency; Vibration leveling device for production line: Core parameters: vibration frequency 50Hz, vibration time 3 seconds, amplitude ≤1mm; Function: When the sand-filled substrate passes through, the device uses high-frequency, small-amplitude vibration to evenly spread the colored sand over the area surrounded by the indentation, so that the final thickness is flush with the copper wire (thickness error ≤0.05mm), replacing manual scraping (manual error ±0.1mm), ensuring that the sand filling thickness of all substrates is consistent, and improving the visual uniformity of the finished product.

[0024] The tunnel-type UV curing machine has a wavelength of 365nm, a power of 1000W, and a conveying speed of 1m / min. It cures the adhesive layer for 30 seconds using UV light irradiation, achieving a curing effect that meets the following formula: ; Specifically, the equipment parameters, formulas, and functions are explained in detail: Wavelength 365nm: The effective curing wavelength of UV light, suitable for photoinitiators of UV-curable adhesives (curing efficiency is highest at 365nm wavelength); Power 1000W: Provides sufficient energy to ensure rapid curing of the adhesive layer and avoids incomplete curing due to insufficient power; Conveying speed 1m / min: Matches the rhythm of the production line, and the curing time for a single substrate is exactly 30 seconds, eliminating the need for manual waiting; Formula annotation: : Adhesive layer curing degree (unit: relative value, ≥95% is acceptable), reflects the hardness and adhesion of the adhesive layer after curing; Curing factor (fixed at 0.0015, obtained by calibrating the UV curing adhesive type and equipment wavelength); UV curing machine power (unit: W, here it is 1000W); : Irradiation time of adhesive layer (unit: s, here it is 30s); Function: The curing effect is quantified by formula. The parameters are substituted to calculate (C=0.0015×1000×30=45) (relative value. In actual production, it needs to be verified by combining hardness tester test (adhesive layer hardness ≥6H)). This ensures that the curing degree of the adhesive layer of each substrate is consistent and avoids adhesive layer peeling or wear due to insufficient curing.

[0025] The method of use and working principle of this invention are as follows: This invention requires a complete process including preliminary preparation, substrate pretreatment, AI intelligent image generation, laser engraving, semi-automatic wire cutting, standardized sand filling and sealing, and quality inspection and packaging. First, the moisture content of the multi-layer solid wood board is checked using a moisture content tester, and the parameters of equipment such as the industrial-grade multi-head CO2 laser engraving machine are calibrated. Next, the substrate is fed into a fully automatic cutting machine to be cut into standard 40cm×60cm sizes. After processing on a multi-station grinding production line, it is placed in a constant temperature drying oven to dry until the moisture content meets the standard. An image is generated using AI, and the line drawing is extracted. Then, the substrate is transferred to the laser engraving station via a substrate stacking conveyor. Subsequently, the line drawing is loaded into the batch layout system of the engraving software, utilizing automatic positioning... The clamping system fixes four substrates, and four independent engraving heads are activated to engrave simultaneously. The real-time depth monitoring unit detects the depth of the indentation using a formula. After engraving, workers scan the code to retrieve pre-cut copper wire packages. After being glued by an automatic dispensing machine, the copper wires are embedded under the assistance of an LED ring light and a 3x magnifying glass. A visual inspection alarm device identifies any deviation in the copper wires. Subsequently, sand is filled into the zoned colored sand bags matched by the scanned code. After being leveled by a vibration leveling device on the production line, the sand is applied by an automatic UV curing adhesive sprayer and then sent to a tunnel-type UV curing machine for 30 seconds of curing. Finally, the finished products are inspected by a laser thickness gauge and a colorimeter. Qualified products are then laminated by an automatic laminating machine and packaged and stored by an intelligent packaging production line. With modular collaboration and automated precision control as its core, the system forms a closed-loop working logic through the complementary functions of each module: First, the substrate pretreatment module standardizes the raw materials. A fully automatic cutting machine and a multi-station grinding production line eliminate differences in substrate size and flatness. A constant temperature drying oven controls the moisture content, providing a uniform base for subsequent processes. The core laser engraving and positioning module uses an industrial-grade multi-head CO2 laser engraving machine to simultaneously engrave four substrates. An automatic positioning fixture system prevents substrate slippage, and a real-time depth monitoring unit dynamically calibrates the indentation depth using a formula to ensure the accuracy of the copper wire embedding reference. The semi-automatic wire cutting module reduces manual labor through a pre-cut copper wire distribution unit. The operation involves a visual inspection and alarm device that corrects copper wire misalignment through high-precision image comparison, balancing efficiency and accuracy. The standardized sand filling and sealing module relies on zoned colored sand bags to avoid color mixing, while the production line vibration leveling device ensures uniform colored sand thickness. The tunnel-type UV curing machine achieves rapid curing of the adhesive layer based on a formula, significantly shortening the production cycle. Finally, the quality inspection and packaging module uses laser thickness gauges and colorimeters to screen qualified finished products, and the intelligent packaging line achieves standardized packaging. The overall process, through pre-processing to eliminate differences, carving to ensure accuracy, standardized wire filling and sand filling, and inspection to ensure qualification, solves the pain points of low efficiency and poor consistency in traditional processes, enabling mass production of laser wire sand paintings.
