Description

Technical Field

[0001] The present invention belongs to but is not limited to the field of molding production technology, and in particular relates to an intelligent stone molding maker and method based on three-dimensional scanning and multi-level technology. Background Art

[0002] Molding technology can be traced back to the ancient civilization period, when people began to use simple molds and plastic materials to make various tools and utensils. With the passage of time, molding technology has continued to develop and improve, and gradually formed a variety of different craft schools and production methods. In modern industrial production, molding technology has become an important molding process, widely used in many fields such as automobiles, home appliances, electronic products, and medical devices. At the same time, handmade molding technology has also been widely used in the fields of art production and toy making due to its unique artistry and personalized characteristics. The basic principle of molding is to inject heated and softened or fluid materials into the mold, and solidify the materials inside the mold by applying pressure and temperature. However, there are problems of human error and instability in the traditional handmade process.

[0003] Through the above analysis, the problems and defects of the prior art are as follows:

[0004] The human errors and instability problems that exist in the traditional manual production process. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides an intelligent stone mold manufacturing device and method based on three-dimensional scanning and multi-level technology.

[0006] The present invention is implemented as follows: an intelligent stone molding manufacturing method based on three-dimensional scanning and multi-level technology, comprising the following steps:

[0007] Step 1: Automatic batching and delivery of raw materials

[0008] The intelligent control system is used to dispatch the automatic batching unit of raw materials according to the preset molding formula instructions. The sensors monitor the remaining materials in different storage bins, and the automatic batching unit accurately puts raw materials such as resin, cement, sand powder and additives into the conveying channel according to the proportion, and then conveys them to the mixing unit. This process ensures the accurate proportion of different materials and the consistency of the quality of the mixture.

[0009] Step 2: Mixing and Adjustment

[0010] After the mixing unit receives the ingredients, multiple agitators perform mixing operations according to the parameters set by the control system; the mixing speed and time are adjusted by the intelligent control system according to the requirements of different materials to ensure that the raw materials are mixed evenly to form a mixture with different physical properties; this step provides the basic material for molding, which has high fluidity and plasticity for subsequent injection molding.

[0011] Step 3: Mold injection and molding

[0012] The mixed material is injected into the mold injection unit through an automatic injection system; the robotic arm evenly distributes the material in the mold according to the size and shape of the mold, and removes bubbles by applying appropriate pressure and vibration to ensure the density and detail of the molding; this step ensures that the appearance, hardness and texture simulation of the finished molded product are consistent with real rocks and fossils.

[0013] Step 4: Curing and preliminary shaping

[0014] After the injection molding is completed, the mold enters the curing unit, and the temperature and humidity are adjusted through the temperature control system to control the curing time and ensure that the molding material hardens in a stable environment. During this process, the system automatically adjusts the temperature curve according to the characteristics of the material (such as resin or cement). After curing, the intelligent carving arm performs preliminary carving and shaping on the surface to make the appearance of the mold closer to the real rock or fossil shape.

[0015] Step 5: Polishing and coloring

[0016] After the molding is cured, it enters the grinding unit. The system automatically selects the appropriate grinding wheel according to the set smoothness and surface treatment requirements, and gradually performs fine grinding on the surface to ensure the surface is flat and modify the details. After grinding, the mold is moved to the coloring unit. The robot uses the preset color scheme and spraying technology to accurately color the mold to create a realistic visual effect, making it look the same as real rocks and fossils.

[0017] Step 6: Quality Inspection and Adjustment

[0018] The quality inspection unit uses laser scanners and image recognition technology to inspect the molding; by identifying problems such as bubbles, cracks, surface unevenness, and whether the color meets the preset scheme, the system automatically makes adjustments or returns to the finishing step to ensure that the molding meets high quality standards.

[0019] Step 7: Intelligent management and control

[0020] The entire process is coordinated and managed by a central intelligent control system. Users can set recipes, morphology designs and processing requirements through the interface. The system records the data of each manufacturing and supports remote control and operation to facilitate batch production or process optimization. The system can also make real-time adjustments based on actual production conditions to ensure efficient operation.

[0021] Step 8: Waste recycling and environmental protection treatment

[0022] Waste and residues generated during the manufacturing process are processed through a waste recovery unit, which can separate recyclable materials and reintroduce them into the manufacturing process, reducing waste and meeting environmental protection requirements.

[0023] Further, the molding method comprises the following steps:

[0024] Step 1: Material selection and preparation

[0025] 1.1 Select representative rocks and fossils as the original model to ensure the structural integrity and details of the model;

[0026] 1.2 Prepare various stone element samples to replicate the texture and color of the original model and ensure the natural effect of the finished product;

[0027] 1.3 Prepare a variety of resin materials suitable for molding, including high-strength resin and transparent resin, for the expression of different textures;

[0028] Step 2: Molding process

[0029] 2.1 Use a high-precision 3D scanner to perform three-dimensional scanning on the original rock or fossil to obtain an accurate digital model to ensure the accuracy of mold making

[0030] 2.2 Based on the 3D scanning data, use customized mold equipment to make a negative mold that matches the original model;

[0031] 2.3 Apply release agent evenly inside the female mold to ensure that the mold is easy to disassemble;

[0032] 2.4 Mix the resin material with the selected stone element sample in proportion and pour it into the negative mold to ensure that the material fully fills the mold and avoids the generation of bubbles and gaps;

[0033] Step 3: Shaping and Strengthening

[0034] 3.1 Before the resin material hardens, shape the model in the mold to ensure the realism and accuracy of the details;

[0035] 3.2 Add reinforcement materials, such as fiber mesh or reinforcing agents, to further enhance the structural strength and avoid cracking or deformation of the model;

[0036] 3.3 After the resin material is solidified, take the model out of the negative mold and check the integrity of the model;

[0037] Step 4: Sanding and painting

[0038] 4.1 Perform preliminary polishing on the demoulding model to remove excess surface material and ensure a smooth surface;

[0039] 4.2 Use fine sandpaper to further polish to improve the fineness and realism of the model surface;

[0040] 4.3 According to the color of the original rock or fossil, hand-coloring is carried out, and pigments or dyes are used for multi-level color processing to achieve a simulation effect;

[0041] Step 5: Post-production and processing

[0042] 5.1 Oxidation treatment: Apply an oxidant to the surface of the model to simulate the oxidation effect during natural weathering, so that the model presents a naturally aged texture;

[0043] 5.2 Injection technology: Use high-precision tools to inject patterns on the surface of the model to imitate the natural texture and fine cracks of rocks or fossils, making the model more realistic;

[0044] 5.3 Glaze treatment: After the oxidation and injection process, the model is treated with transparent glaze to further protect the model surface and improve the gloss and durability.

[0045] Furthermore, the shaping and reinforcement:

[0046] After the resin material is solidified, the preliminary model is removed from the mold;

[0047] Use cement, sand powder and other additives of different specifications to strengthen and shape the model;

[0048] Support structures or fillers can be added to the model as needed.

[0049] Further, the polishing and coloring:

[0050] Fine sanding of the model to remove surface blemishes and uneven parts;

[0051] Use professional painting techniques to paint models to restore the color and texture of the original rock or fossil;

[0052] During the coloring process, multi-layer painting and gradient techniques can be used.

[0053] Furthermore, the three-dimensional scanning accuracy in step 2.1 is 0.01 mm to 0.05 mm, ensuring that the scanned digital model can capture the tiny texture details of the original rock or fossil, so as to improve the accuracy of the mold and the simulation effect of the final product.

[0054] The mixing ratio of the resin material and the stone element in step 2.4 is adjusted according to the texture and color of the original model, wherein the addition amount of the stone element is 10% to 40%, and the proportion of the resin material is 60% to 90%, to ensure that the hardness and simulation texture of the finished model match the original model.

[0055] Furthermore, the reinforcement materials used in step 3.2 include carbon fiber mesh, glass fiber or nano-reinforcement agent. By evenly distributing these reinforcement materials in the resin material, the overall structural strength of the model can be increased by 30% to 50% to avoid deformation and cracking of the model during long-term display or use.

[0056] Furthermore, the coloring process in step 4.3 uses a multi-layer spraying process, first spraying the base color, then coloring the texture of the middle layer, and finally adjusting the details. The pigment used is a weather-resistant pigment to ensure that the color of the model is not easy to fade or deteriorate during long-term display.

[0057] Furthermore, the oxidation treatment in step 5.1 uses an oxidant and a humidity and temperature control system that simulates the natural environment. The oxidation treatment lasts for 2 to 8 hours at an ambient temperature of 20°C to 40°C to simulate the oxidation effect of real rocks or fossils under natural weathering conditions, so that the model surface presents a natural aging texture and feel.

[0058] Furthermore, the glaze treatment in step 5.3 uses UV-curable transparent resin, the glaze thickness is 0.1mm to 0.3mm, and the glaze is cured by light during the glaze process to ensure the transparency and durability of the glaze layer, so that the model maintains high gloss and wear resistance during long-term use.

[0059] Another object of the present invention is to provide an intelligent stone mold manufacturing device based on a three-dimensional scanning and multi-level process intelligent stone mold manufacturing method, comprising:

[0060] Automatic raw material batching unit: It consists of multiple raw material storage bins, which store different types of resin materials, cement, sand powder and various additives. The remaining amount of raw materials is monitored by sensors, and the proportion of different materials is automatically adjusted according to the formula.

[0061] Mixing unit: Multiple agitators and automatic mixing devices are used to mix the different materials fed into the batching unit according to the proportions. The agitator adjusts the mixing speed and time as needed to ensure that the resin, cement, sand powder and additives are evenly mixed, and can generate various material combinations according to different molding requirements. The entire mixing process is monitored by a central intelligent control system.

[0062] Mold injection unit: equipped with multiple mold trays for injecting mixed materials into the mold; the robot arm of the injection unit realizes automatic injection, ensuring that the material is evenly distributed in the mold, and removes bubbles through pressure and vibration to enhance the density and detail of the molding; the robot arm can adapt to molds of different sizes and shapes, providing high flexibility;

[0063] Curing and shaping unit: After injection molding, the mold enters the curing unit for temperature control. The unit is equipped with a heating system and a cooling system to control the curing temperature and time to ensure that the hardening process of the mold is stable and uniform. It uses an intelligent temperature and humidity sensor to automatically adjust the environmental conditions according to the curing requirements of different materials.

[0064] In addition, after curing, the intelligent engraving arm can be used for preliminary shaping, engraving and fine-tuning the mold surface details to form a preliminary molding form;

[0065] Grinding and coloring unit: After curing and shaping, the mold enters the grinding unit, which is equipped with an automatic grinding device. According to the set smoothness requirements, the surface of the mold is gradually polished to remove uneven surfaces and add details. Grinding wheels of different grits can be automatically switched according to needs;

[0066] After polishing, the mold will enter the coloring unit, where the coloring robot arm will color the mold surface through automatic spraying or brushing technology according to the pre-set color scheme;

[0067] Quality inspection and adjustment unit: At each stage of molding manufacturing, the system is equipped with high-precision laser scanners and image recognition technology to perform quality inspections; the inspection unit identifies whether there are defects, bubbles or cracks on the molding surface, whether the color meets the preset requirements, and automatically adjusts according to the inspection results;

[0068] Intelligent control system: The entire manufacturing machine is managed by a central intelligent control system, which integrates automatic batching, injection molding, curing, grinding, coloring, and detection functions; the system supports parametric customization, and users can set specific requirements such as molding material formula, shape design, and surface treatment through the interface; the system also supports remote operation and data recording, which is convenient for users to perform multiple manufacturing, record parameters, and optimize processes;

[0069] Waste recovery and environmental protection unit: used to recover waste and residues from the manufacturing process; the waste is processed and re-enters the manufacturing process.

[0070] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present invention are as follows:

[0071] First, through the molding method, rock and fossil models with realistic appearance, specific gravity, hardness and shape can be produced to meet the needs of exhibition.

[0072] The design of the intelligent stone mold maker realizes the mechanization and intelligence of the production process, improves production efficiency and reduces labor costs.

[0073] The quality and stability of the model are guaranteed by precise material adding, mixing and molding systems.

[0074] The problems of human error and instability existing in the traditional manual production process have been effectively solved.

[0075] It solves the problem of wear and tear of fossils and rock specimens caused by human and natural factors during exhibition.

[0076] Through the application of intelligent manufacturers, the demand for efficient and mass production of rock and fossil models in exhibition venues has been realized.

[0077] Second, the technical solution of the present invention solves the following technical problems in the prior art in industrial applications and has achieved significant technical progress:

[0078] 1) Technical problems of existing technologies

[0079] (1) Insufficient mold accuracy and detail restoration:

[0080] Traditional molding processes rely on hand carving and low-precision molds, which cannot accurately replicate the subtle textures and shapes of the original model. Especially when replicating the complex texture of rocks or fossils, details are easily lost, affecting the simulation effect of the final product.

[0081] (2) Limited material selection and texture performance:

[0082] Existing technologies are usually relatively simple in material selection, especially the texture and color of stone and fossils are difficult to replicate with traditional materials, resulting in the simulation effect being not realistic enough, and the material strength is not high, and the model is prone to cracking or deformation.

[0083] (3) Lack of multifunctional post-processing technology:

[0084] Traditional molding methods mostly focus on surface polishing and simple coloring processes, which make it difficult to simulate natural aging, oxidation and weathering effects. They lack complex post-processing processes such as injection molding and simulated oxidation treatment, resulting in insufficient simulation and poor visual effects of the model.

[0085] 2) Significant technical progress in technical solutions

[0086] (1) Improve the accuracy and detail restoration of the mold:

[0087] The present invention uses high-precision 3D scanning technology to accurately capture the three-dimensional form of the original rock or fossil, and combines it with customized mold making technology to ensure that every detail can be perfectly presented in the final molding process. This significantly improves the accuracy of the model and the restoration of details, especially when dealing with complex shapes and subtle textures.

[0088] (2) Provide a variety of material options to enhance texture performance:

[0089] The present invention uses a combination of multiple stone elements and high-performance resin materials to accurately simulate the real texture and color of different rocks or fossils. By mixing stone powder, mineral particles and resin materials in proportion, the prepared model not only has visual authenticity, but also has improved mechanical properties, greatly improving the strength and durability of the model, and avoiding the problem of easy cracking of traditional models.

[0090] (3) Introduce post-oxidation and graining treatment to improve simulation effect:

[0091] The present invention adds complex post-processing processes after molding, including oxidation treatment and injection process. These steps can simulate the long-term weathering and oxidation process of rocks or fossils in the natural environment, so that the surface of the model has a real aging and cracking effect. Compared with the traditional polishing and coloring process, the post-processing of the present invention makes the model more historical and natural, further improving the simulation effect.

[0092] (4) Improve production efficiency and adaptability:

[0093] The 3D scanning and customized mold technology adopted by the present invention makes the repetitive operations in the model making process simple and efficient. Through digital production means, high-precision models can be quickly reproduced in batches, solving the problems of low efficiency and high cost of traditional manual production. This method is particularly suitable for large-scale application in the fields of cultural relics restoration, museum display, etc., and significantly improves the efficiency of industrial applications.

[0094] 3) The actual application effect of technological progress

[0095] In industrial applications, especially in the fields of museum exhibitions, cultural relics restoration, scientific research and teaching, the present invention provides a highly simulated, durable model making solution with complex textures and textures, making up for the deficiencies in the prior art. Its technical advantages are:

[0096] Improved model simulation effect: Through precise 3D scanning and post-processing, the model surface shows a texture and feel that is extremely similar to the original object, solving the problem of poor detail performance in existing technologies.

[0097] Improved material properties: The combination of resin material and stone elements not only gives the model a realistic appearance, but also improves its mechanical properties, making it more durable during long-term display or use.

[0098] Strong process scalability: The process flow of the present invention is highly flexible and scalable, can adapt to the production needs of models of different sizes and materials, and can be quickly mass-produced, with high industrial value.

[0099] In summary, the present invention has achieved significant technological progress by solving the problems of insufficient mold precision, limited material performance and imperfect post-processing in the prior art, and has strong practical application value and promotion potential.

The sensors monitor the remaining materials in different storage bins, and the automatic batching unit accurately puts raw materials such as resin, cement, sand powder and additives into the conveying channel according to the proportion, and then conveys them to the mixing unit. This process ensures the accurate proportion of different materials and the consistency of the quality of the mixture.

[0107] Step 2: Mixing and Adjustment

[0108] After the mixing unit receives the ingredients, multiple agitators perform mixing operations according to the parameters set by the control system; the mixing speed and time are adjusted by the intelligent control system according to the requirements of different materials to ensure that the raw materials are mixed evenly to form a mixture with different physical properties; this step provides the basic material for molding, which has high fluidity and plasticity for subsequent injection molding.

[0109] Step 3: Mold injection and molding

[0110] The mixed material is injected into the mold injection unit through an automatic injection system; the robotic arm evenly distributes the material in the mold according to the size and shape of the mold, and removes bubbles by applying appropriate pressure and vibration to ensure the density and detail of the molding; this step ensures that the appearance, hardness and texture simulation of the finished molded product are consistent with real rocks and fossils.

[0111] Step 4: Curing and preliminary shaping

[0112] After the injection molding is completed, the mold enters the curing unit, and the temperature and humidity are adjusted through the temperature control system to control the curing time and ensure that the molding material hardens in a stable environment. During this process, the system automatically adjusts the temperature curve according to the characteristics of the material (such as resin or cement). After curing, the intelligent carving arm performs preliminary carving and shaping on the surface to make the appearance of the mold closer to the real rock or fossil shape.

[0113] Step 5: Polishing and coloring

[0114] After the molding is cured, it enters the grinding unit. The system automatically selects the appropriate grinding wheel according to the set smoothness and surface treatment requirements, and gradually performs fine grinding on the surface to ensure the surface is flat and modify the details. After grinding, the mold is moved to the coloring unit. The robot uses the preset color scheme and spraying technology to accurately color the mold to create a realistic visual effect, making it look the same as real rocks and fossils.

[0115] Step 6: Quality Inspection and Adjustment

[0116] The quality inspection unit uses laser scanners and image recognition technology to inspect the molding; by identifying problems such as bubbles, cracks, surface unevenness, and whether the color meets the preset scheme, the system automatically makes adjustments or returns to the finishing step to ensure that the molding meets high quality standards.

[0117] Step 7: Intelligent management and control

[0118] The entire process is coordinated and managed by a central intelligent control system. Users can set recipes, morphology designs and processing requirements through the interface.

[0174] 2.4 Mix the resin material with the selected stone element sample in proportion and pour it into the negative mold to ensure that the material fully fills the mold and avoids the generation of bubbles and gaps;

[0175] Step 3: Shaping and Strengthening

[0176] 3.1 Before the resin material hardens, shape the model in the mold to ensure the realism and accuracy of the details;

[0177] 3.2 Add reinforcement materials, such as fiber mesh or reinforcing agents, to further enhance the structural strength and avoid cracking or deformation of the model;

[0178] 3.3 After the resin material is solidified, take the model out of the negative mold and check the integrity of the model;

[0179] Step 4: Sanding and painting

[0180] 4.1 Perform preliminary polishing on the demoulding model to remove excess surface material and ensure a smooth surface;

[0181] 4.2 Use fine sandpaper to further polish to improve the fineness and realism of the model surface;

[0182] 4.3 According to the color of the original rock or fossil, hand-coloring is carried out, and pigments or dyes are used for multi-level color processing to achieve a simulation effect;

[0183] Step 5: Post-production and processing

[0184] 5.1 Oxidation treatment: Apply an oxidant to the surface of the model to simulate the oxidation effect during natural weathering, so that the model presents a naturally aged texture;

[0185] 5.2 Injection technology: Use high-precision tools to inject patterns on the surface of the model to imitate the natural texture and fine cracks of rocks or fossils, making the model more realistic;

[0186] 5.3 Glaze treatment: After the oxidation and injection process, the model is treated with transparent glaze to further protect the model surface and improve the gloss and durability.

[0187] Furthermore, the shaping and reinforcement:

[0188] After the resin material is solidified, the preliminary model is removed from the mold;

[0189] Use cement, sand powder and other additives of different specifications to strengthen and shape the model;

[0190] Support structures or fillers can be added to the model as needed.

[0191] Further, the polishing and coloring:

[0192] Fine sanding of the model to remove surface blemishes and uneven parts;

[0193] Use professional painting techniques to paint models to restore the color and texture of the original rock or fossil;

[0194] During the coloring process, multi-layer painting and gradient techniques can be used.

[0195] Furthermore, the three-dimensional scanning accuracy in step 2.1 is 0.01 mm to 0.05 mm, ensuring that the scanned digital model can capture the tiny texture details of the original rock or fossil, so as to improve the accuracy of the mold and the simulation effect of the final product.

[0196] The mixing ratio of the resin material and the stone element in step 2.4 is adjusted according to the texture and color of the original model, wherein the addition amount of the stone element is 10% to 40%, and the proportion of the resin material is 60% to 90%, to ensure that the hardness and simulation texture of the finished model match the original model.

[0197] Furthermore, the reinforcement materials used in step 3.2 include carbon fiber mesh, glass fiber or nano-reinforcement agent. By evenly distributing these reinforcement materials in the resin material, the overall structural strength of the model can be increased by 30% to 50% to avoid deformation and cracking of the model during long-term display or use.

[0198] Furthermore, the coloring process in step 4.3 uses a multi-layer spraying process, first spraying the base color, then coloring the texture of the middle layer, and finally adjusting the details. The pigment used is a weather-resistant pigment to ensure that the color of the model is not easy to fade or deteriorate during long-term display.

[0199] Furthermore, the oxidation treatment in step 5.1 uses an oxidant and a humidity and temperature control system that simulates the natural environment. The oxidation treatment lasts for 2 to 8 hours at an ambient temperature of 20°C to 40°C to simulate the oxidation effect of real rocks or fossils under natural weathering conditions, so that the model surface presents a natural aging texture and feel.

[0200] Furthermore, the glaze treatment in step 5.3 uses UV-curable transparent resin, the glaze thickness is 0.1mm to 0.3mm, and the glaze is cured by light during the glaze process to ensure the transparency and durability of the glaze layer, so that the model maintains high gloss and wear resistance during long-term use.

[0225] 3) Shaping and reinforcement:

[0226] Initial shaping of the resin to preserve the natural hanging form of the stalactites. Adding fiber reinforcements to ensure the model does not break at larger sizes.

[0227] 4) Polishing and coloring:

Coarse-grained sand and resin are mixed and poured into the negative mold to ensure that the footprint shape is completely reproduced.

[0234] 3) Shaping and reinforcement:

[0235] Use tools to finely carve the edges of the footprints to maintain their authenticity. Use reinforcement materials such as fiberglass mesh to strengthen the model and prevent it from wear and tear during long-term display.

[0236] 4) Polishing and coloring:

[0237] The footprints were lightly sanded to preserve their roughness. They were then painted using tan and grey pigments to simulate soil and fossil surfaces. Finally, tiny cracks and artificial weathering were injected to further enhance the realism of the model.
