[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1 to 3 This invention discloses a method for processing stone for kitchen cabinets, comprising the following steps:

[0034] S1 and 3D precision measuring instruments are used for on-site data acquisition;

[0035] S2. Generate a 3D model based on the scanned data and generate processing drawings;

[0036] S3. Use a CNC high-pressure water jet cutting device to cut the stone in the factory;

[0037] S4. The workers will bring the cut stone to the site for installation.

[0038] In use, the dimensions on site are first measured using a 3D precision measuring instrument. The measured dimensional data is then input into 3D modeling software to generate a 3D image. After the dimensions are verified to be correct, processing drawings and processing data are generated. Based on the processing drawings and processing data, the stone is cut in the factory by a high-precision CNC high-pressure water jet cutting device to form prefabricated components, avoiding dust pollution of the installation environment caused by on-site cutting. Finally, the prefabricated components are transported to the installation site and installed by staff, ultimately achieving a dust-free installation process.

[0039] The preferred 3D precision measuring instrument is a 3D measuring instrument, which is a high-precision measuring device widely used in engineering measurement and manufacturing industries to perform multi-dimensional, high-precision measurements of objects.

[0040] The main steps of on-site data collection:

[0041] 1. Tabletop preparation: Ensure that the tabletop surface to be measured is clean, smooth, and free of impurities, and place it in a stable position.

[0042] 2. Measuring instrument settings: Ensure the measuring instrument is in normal working condition. Select the appropriate measuring instrument and probe according to the actual situation, and install and adjust them correctly.

[0043] 3. Scanning: The surface of the table is scanned using measuring instruments to obtain three-dimensional coordinate point cloud data. For large or complex tables, the scan can be divided into several regions, and the data from each region can be stitched together using software.

[0044] 4. Data Processing: The acquired 3D data is processed using relevant software, including filtering, registration, and reconstruction of point cloud data. The data can also be rotated at any angle to facilitate subsequent analysis and design.

[0045] 5. Data Output: The processed data is output as two-dimensional or three-dimensional model data for subsequent analysis operations such as dimensions and shape. The software can also generate document reports displaying various measurement data and graphics of the tabletop.

[0046] It is important to note that operating a 3D measuring instrument requires professional skills and experience, as well as knowledge of measurement principles, instrument signal characteristics, data processing and analysis, in order to ensure the accuracy and reliability of the measurement results.

[0047] The data obtained from on-site measurements is initially processed by the attached platform to generate simplified drawings. The data is then synchronously transmitted to the design office via a mobile phone connected to the 3D measuring instrument via Bluetooth. Detailed drawings are then automatically generated using software (such as CAD) and reviewed by relevant designers.

[0048] Advanced computer-aided design (CAD) and computer-aided manufacturing (CAM) technologies are adopted. By writing digital programs, CAD drawings and the measurement and cutting of stone are automatically completed based on the finished product specifications.

[0049] After precise on-site measurement and CNC machine tool processing, the stone countertop perfectly fits the kitchen space, requiring no further processing. The final installation can be completed simply by a few professional installers transporting the finished product to the site. The entire installation process generates no additional environmental pollution, protecting the environment and the health of the workers to the greatest extent possible.

[0050] To implement the above-mentioned cabinet stone processing method, we propose a CNC high-pressure water jet cutting device for processing, including: a bracket 7, a third horizontal moving module 9 fixedly connected to both sides of the top of the bracket 7, a connecting block 6 fixedly connected to the movable end of the third horizontal moving module 9, the two ends of a second horizontal moving module 3 fixedly connected between the two connecting blocks 6, and a sandblasting cutting water jet 4 fixedly connected to the movable end of the second horizontal moving module 3.

[0051] The moving direction of the movable end of the second horizontal moving module 3 is spatially perpendicular to the moving direction of the movable end of the third horizontal moving module 9.

[0052] A material support assembly is located directly below the sandblasting and cutting waterjet 4, and the material support assembly is located inside the bracket 7.

[0053] In use, two third horizontal moving modules 9 installed on the bracket 7 drive the corresponding connecting blocks 6 to move, which in turn drive the middle second horizontal moving module 3 to move. The sandblasting waterjet 4 is installed at the moving end of the second horizontal moving module 3. The sandblasting waterjet 4 is driven to move by the second horizontal moving module 3. The moving direction of the moving end of the second horizontal moving module 3 is spatially perpendicular to the moving direction of the moving end of the third horizontal moving module 9, thus realizing the movement of the sandblasting waterjet 4 in the X and Y directions. By placing a sheet of a specified thickness on the material support assembly, and then using the cooperation of the second horizontal moving module 3 and the third horizontal moving module 9 to move the sandblasting waterjet 4 in the plane, the sheet is cut into a specified shape, thus completing the processing of the sheet.

[0054] The second horizontal moving module 3 and the third horizontal moving module 9 have the same structure, both preferably consisting of a ball screw and a motor. The motor is connected to the screw shaft, causing the moving end of the ball screw to move laterally.

[0055] Further optimization of the solution: the material support component includes a waste recycling bin 11, which is fixedly connected to the bracket 7. A perforated tray 8 is installed on the top of the waste recycling bin 11. The perforated tray 8 is used to place materials and is located directly below the sandblasting and cutting water jet 4.

[0056] The perforated support plate 8 is used to support the plate and also facilitates the flow of the water-sand mixture generated by the sandblasting and cutting water jet 4 into the waste recycling bin 11 below the perforated support plate 8 for recycling.

[0057] Furthermore, a pressing part is provided on the outside of the bracket 7. The pressing part includes a gantry frame 2. A first horizontal moving module 1 is fixedly connected to the top of the gantry frame 2. The movable end of the first horizontal moving module 1 is fixedly connected to the fixed end of the vertical moving module 5. The movable end of the vertical moving module 5 is fixedly connected to the top of the pressure plate 10. The bottom end of the pressure plate 10 is located directly above the hollow support plate 8.

[0058] The first horizontal moving module 1 and the vertical moving module 5 have the same structure as the second horizontal moving module 3, and are preferably ball screws and motors.

[0059] The vertical moving module 5 is used to drive the pressure plate 10 to move in the vertical direction. After the plate is placed on the hollow support plate 8, the pressure plate 10 descends and presses on the top of the plate to fix the plate during the cutting process.

[0060] Further optimization of the scheme: the sandblasting cutting water jet 4 includes a water nozzle 402, which is fixed to the movable end of the second horizontal moving module 3. The bottom end of the water nozzle 402 is fixed to a sandblasting mixing component 403 by a thread, and the bottom end of the sandblasting mixing component 403 is fixed to a nozzle 411 by a thread. The liquid outlet end of the sandblasting mixing component 403 is connected to the liquid inlet end of the nozzle 411. The water nozzle 402 is provided with a high-pressure water channel 401, and the liquid outlet end of the high-pressure water channel 401 is connected to the liquid inlet end of the sandblasting mixing component 403.

[0061] The high-pressure water channel 401 is equipped with an ultrasonic aeration unit.

[0062] The waterjet cutting blade 4 includes a water nozzle 402 for introducing high-pressure water. A sandblasting mixing component 403 is threadedly fixed below the water nozzle 402. The sandblasting mixing component 403 is used to introduce sand and mix it with high-pressure water, which is then sprayed out by a nozzle 411 threaded to the bottom of the sandblasting mixing component 403 to achieve plate cutting. At the same time, an ultrasonic aeration section is provided in the high-pressure water flow channel 401. When water enters the high-pressure water flow channel 401, it generates high-frequency vibration through the ultrasonic aeration section, causing the water passing through the ultrasonic aeration section to be locally affected by the vibration and generate bubbles. The bubbles will mix with the sand along with the high-pressure water and impact the plate. After the bubbles come into contact with the plate, they will break and generate a cavitation effect. Under the multiple effects of water cutting, sand friction and cavitation, the cutting efficiency is improved. Cavitation can also further remove burrs from the cut surface, making the cut surface smoother.

[0063] Further optimization of the design: the ultrasonic aeration section includes several piezoelectric ceramic rings 407, which are coaxially arranged at the bottom end of the high-pressure water channel 401. The top of the piezoelectric ceramic ring 407 is fitted with a retaining ring 409, which is coaxially fixed to the inner wall of the high-pressure water channel 401. The bottom of the piezoelectric ceramic ring 407 is fitted with the inner wall of the sandblasting mixing component 403.

[0064] To further optimize the design, a polytetrafluoroethylene coating 408 is applied to the through-hole of the piezoelectric ceramic ring 407.

[0065] Several piezoelectric ceramic rings 407 are stacked together and installed at the bottom of the high-pressure water channel 401 under the limiting cooperation of the retaining ring 409 and the inner wall of the sandblasting mixing component 403. After the high-pressure water enters the high-pressure water channel 401, it enters the sandblasting mixing component 403 through the through hole in the middle of each piezoelectric ceramic ring 407. By energizing the piezoelectric ceramic rings 407, each piezoelectric ceramic ring 407 vibrates, causing the local high-pressure water to vibrate and generate bubbles. The bubbles enter the sandblasting mixing component 403 with the water flow.

[0066] The polytetrafluoroethylene coating 408 inside the through hole of the piezoelectric ceramic ring 407 reduces the wear caused by the impact of high-pressure water on the piezoelectric ceramic ring 407.

[0067] The design is further optimized by providing a mixing chamber 414 inside the sandblasting mixing component 403. The mixing chamber 414 is connected to the high-pressure water channel 401. Sand inlet pipes 404 are connected to both sides of the mixing chamber 414. A mixing jet pipe 412 is coaxially fixed inside the mixing chamber 414. A jetting channel 413 is coaxially opened inside the mixing jet pipe 412. The jetting channel 413 is connected to the mixing chamber 414 and to the nozzle 411.

[0068] The top of the mixing injection pipe 412 is provided with a constriction 410, which is located directly below the discharge end of the sand inlet pipe 404.

[0069] The mixing chamber 414 is used to mix the sand entering the sand inlet pipe 404 with high-pressure water. After being concentrated and pressurized by the constriction 410 at the top of the mixing spray pipe 412, the sand enters the mixing spray pipe 412 and is moved to the nozzle 411 by the mixing spray pipe 412.

[0070] In a further optimized design, the water nozzle 402 is provided with several circumferentially spaced first branch channels 406. The inlet end of the first branch channel 406 is connected to the high-pressure water channel 401, and the outlet end of the first branch channel 406 is connected to the inlet end of the second branch channel 416. The second branch channel 416 is located in the sandblasting mixing assembly 403, and the outlet end of the second branch channel 416 is connected to the mixing chamber 414.

[0071] Several first branch channels 406 are provided inside the water nozzle 402. Before entering the through hole in the middle of the piezoelectric ceramic ring 407, the high-pressure water will be diverted to the first branch channel 406 and then flow into the second branch channel 416 and into the mixing chamber 414. This part of the water flows through one side of several piezoelectric ceramic rings 407, which helps to carry away the heat generated by the vibration of the piezoelectric ceramic rings 407 and extend the service life of the piezoelectric ceramic rings 407.

[0072] In a further optimized design, a sealing ring 405 is provided at the joint between the sandblasting mixing component 403 and the water nozzle 402, and the sealing ring 405 is coaxially embedded in the top of the sandblasting mixing component 403.

[0073] In a further optimized design, a nozzle 415 is coaxially provided inside the nozzle 411, and the liquid inlet end of the nozzle 415 is connected to the liquid outlet end of the injection channel 413.

[0075] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the present invention.
