Description

Technical Field

[0001] The present invention relates to the field of slate processing equipment, and particularly to an intelligent polishing machine for polishing the surface of slate. Background Art

[0002] After being cut, the stone materials form blocky or sheet-like stone slabs, which are mainly used for floor laying and stone curtain wall construction. As a key link in fine processing, the surface polishing of slate directly affects the flatness, gloss and aesthetics of the finished product. The following problems generally exist in traditional slate polishing equipment: 1. Poor clamping stability: Conventional mechanical clamps rely only on bolts or lever-type pressing, which easily causes displacement or chipping of the slate, especially poor adaptability to special-shaped slates, and low clamping efficiency; 2. Insufficient polishing accuracy: Manually adjusting the pressure of the polishing disc easily leads to over-polishing or under-polishing in some areas, and defects such as moiré patterns and scratches are likely to appear on the surface; 3. Low automation level: The grinding path depends on manual experience, lacking real-time monitoring and dynamic feedback, and it is difficult to ensure batch consistency; 4. Dust and cooling problems: Traditional wet cooling is likely to leave water stains, while dry polishing generates a large amount of dust, which is harmful to the operating environment in the long term; 5. High maintenance cost: The replacement of the polishing disc is complex, and the equipment lacks the ability of data traceability, making it difficult to troubleshoot faults and optimize processes.

[0024] Manual quick-release tooling 25: Please refer to the appendix Figure 6 , the clamping handle 251 is connected by a cross hinge, the inner wall of the semi-circular clamping block 252 is machined with a V-shaped groove, and has an interference fit with the outer diameter of the polishing bracket 22 (interference amount 0.1 mm). The quick-release pin 253 is made of spring steel, and the anti-shearing force is ≥800 N; Magnetic coupling 241: The active end is key-connected to the output shaft of the polishing drive motor 24, the driven end is fixed to the polishing disc 23 through a flange, the air gap distance is 1 mm, and the maximum torque transmission capacity is 50 N·m The usage method of the present invention is as follows: 1. Clamping stage: Horizontally place the stone slab to be polished on the surface of the vacuum adsorption bottom plate 52 of the workbench 1. Start the vacuum pump and control the adsorption groove 521 to form vacuum adsorption through the solenoid valve 53. The adsorption pressure is maintained at -80 kPa to -100 kPa to ensure that the bottom surface of the stone slab fits tightly; Adjust the two adjustable positioning blocks 51 to slide longitudinally along the T-shaped groove of the workbench 1 to the two side edges of the stone slab. After locking, the polyurethane wear-resistant layer of the positioning block 51 contacts the side surface of the stone slab to limit the lateral displacement of the stone slab; At the same time, start the three pen-shaped cylinders 54, and the polyurethane pressing block 56 at the end of the piston rod applies a clamping force of ≥200 N from both sides of the stone slab in a line contact manner; Operate the inclined cylinder 553 of the lateral pressing assembly 55 to push the wedge block 552 to move along the guide rail of the fixed arm 551, and further apply an oblique pressure from the end surface of the stone slab to achieve pneumatic and vacuum composite clamping. The total clamping time of the whole process is ≤10 seconds; 2. Polishing path planning: The binocular vision camera 8 performs high-precision scanning on the surface of the stone slab (resolution 0.1 mm) to generate three-dimensional point cloud data including cracks and depressions; The polishing path planning unit 71 of the intelligent control module 7 automatically generates the movement trajectory of the polishing disc 23 based on the point cloud data, avoiding the defective area and optimizing the polishing sequence; The articulated arm 21 is rigidly combined with the ball screw 32 and the guide pillar 31 of the lifting mechanism 3, and is driven by the lifting servo motor 33 to move vertically. Initially position the polishing disc 23 to a height of 5 mm from the surface of the stone slab.

[0025] 3. Polishing stage: Start the polishing drive motor 24, and drive the polishing disc 23 to rotate at a speed of 800 - 3000 rpm through the magnetic coupling 241. After the grinding layer 233 (diamond composite sintered sheet) of the polishing disc 23 contacts the surface of the stone slab, the pressure sensor 6 at the bottom of the polishing bracket 22 collects the polishing pressure signal in real time (detection range 0 - 500 N, accuracy ±1 N), and feeds the data back to the intelligent control module 7. The module 7 dynamically adjusts the downward stroke of the lifting servo motor 33 and the rotation speed of the polishing drive motor 24 according to the preset pressure curve (such as 150 N in the rough polishing stage and 80 N in the fine polishing stage) to form a pressure - position - speed closed - loop control. At the same time, the atomizing nozzle 41 of the cooling mechanism 4 is adjusted to a spraying angle of 45° through the rotary joint 42, and atomized coolant is sprayed into the polishing area at a flow rate of 0.5 L / min to make the temperature in the contact area ≤60°C. 4. Real - time surface quality monitoring stage: The vision camera 8 takes real - time pictures of the polished surface at an inclination angle of 45°. The intelligent control module 7 converts the image data into a thermogram and displays it on the monitor 10, and judges the polishing uniformity by comparing with the preset glossiness threshold (≥90 GU). When the pressure sensor 6 detects a sudden increase in local pressure (such as ≥120% of the set value), the abnormal warning unit 72 immediately triggers an audible and visual alarm and stops the polishing drive motor 24 urgently to avoid chipping of the stone slab or equipment overload.

[0026] 5. Maintenance stage: When the grinding layer 233 of the polishing disc 23 is worn (thickness < 1 mm), the operator pulls the clamping handle 251 of the manual quick - release tooling 25, compresses the spring auxiliary return mechanism, so that the semi - circular clamping block 252 disengages from the outer diameter of the polishing bracket 22. After pulling out the quick - release pin 253, the old polishing disc 23 is axially pulled out. When replacing the new polishing disc 23, ensure that its buffer layer 232 (silicone hardness 60A) fits the bottom surface of the polishing bracket 22. After the clamping handle 251 is reset, a clamping force of ≥500 N is generated, and the whole replacement process takes ≤1 minute.

[0027] 6. Dust collection and data management: The dust generated during the polishing process is sucked into the cyclone dust collector 93 through the square negative - pressure dust suction port 91 (negative pressure value - 2 kPa) and the corrugated pipe 92, and the separation efficiency ≥95%. The data storage unit 73 of the intelligent control module 7 continuously records the polishing pressure, rotation speed, temperature and trajectory coordinates, and encrypts and transmits the data to the cloud server through the wireless communication interface 74, and integrates with the MES system to generate a report containing process parameters and quality indicators, supporting production batch traceability and process optimization. The present invention is an intelligent polishing machine for polishing the surface of stone slabs, which effectively solves the problems of low efficiency, unstable quality and environmental pollution in traditional stone polishing, and provides reliable equipment support for high - value - added processing of stone materials.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
