Description

Technical Field

[0001] This invention relates to the field of industrial silicon preparation technology, and in particular to a visual intelligent sorting, feeding and rejection device for the preparation of double-layer industrial silicon. Background Technology

[0002] The industrial silicon preparation feeding and rejection equipment is an automated device specifically designed for the pretreatment stage of industrial silicon raw materials. It utilizes machine vision and artificial intelligence technology to perform online detection and intelligent identification of blocky industrial silicon raw materials, and automatically completes the entire process of feeding, conveying qualified products and rejecting unqualified products.

[0003] Currently, industrial silicon sorting and feeding mainly rely on traditional sorting equipment. However, these devices have gradually revealed numerous technical shortcomings over long-term use. For example, traditional sorting equipment often uses a single-layer conveyor structure, capable of only completing a single screening process and lacking a graded purification mechanism. For fine impurities (such as micron-sized dust and trace metal oxides) and large particulate impurities (such as blocky non-metallic inclusions and incompletely reacted raw material agglomerates) mixed in industrial silicon raw materials, a single removal method cannot accurately separate impurities of different particle sizes and characteristics. This results in incomplete removal of fine impurities and easy omission of large particulate impurities. Furthermore, high-quality industrial silicon material is often mistakenly rejected, severely impacting raw material utilization and sorting purity. Additionally, the detection group of traditional equipment... Traditional equipment often uses a single camera or simple sensor, which can only make preliminary identifications based on the appearance of the material. It cannot perform in-depth detection of the chemical composition and microscopic features of impurities. For impurities that are similar in physical form to industrial silicon but have different chemical compositions (such as alumina and silicon carbide), traditional detection methods are difficult to effectively distinguish them. This results in the presence of hidden impurities in the industrial silicon after sorting, which can easily lead to product defects in subsequent processing. At the same time, a large amount of dust is generated during the sorting process of industrial silicon. Traditional equipment lacks a dedicated cleaning mechanism for detection components. Dust easily adheres to the surface of key components such as detection cameras and sensors, causing the detection accuracy to gradually decrease over time. Frequent shutdowns for manual cleaning are required, which seriously interrupts the continuity of production and reduces overall production efficiency.

[0004] Therefore, this application provides a visual intelligent sorting and rejection device for the preparation of bilayer industrial silicon to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a visual intelligent sorting and feeding rejection device for the preparation of double-layer industrial silicon, so as to solve the problems of traditional sorting methods being single, visual inspection being simple, unable to perform depth inspection, and dust being easily generated during the sorting process, which affects the mechanical effect of visual inspection.

[0012] Optionally, the second rejection assembly further includes a protective plate hinged to one side of the connecting seat. A torsion spring is installed at the hinge point between the connecting seat and the protective plate. A buffer pad is adhered to the other side of the protective plate. A second guide rail is installed on the other side of the connecting seat. A second hydraulic rod is installed on the other side of the second guide rail. Two miniature hydraulic rods are fixedly connected to the output end of the second hydraulic rod. An electric gripper is fixedly connected to the output end of the two miniature hydraulic rods.

[0013] Optionally, the cleaning assembly includes a plurality of first duckbill-shaped nozzles disposed on the inner side of the upper gantry frame, the plurality of first duckbill-shaped nozzles being connected to a U-shaped tube, the bottom end of the U-shaped tube being connected to a plurality of second duckbill-shaped nozzles, the other end of the U-shaped tube being connected to a first connecting tube, the other end of the first connecting tube penetrating the outer wall of the upper gantry frame and connected to a first air guide tube.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, impurities are initially located using a first camera, and then a second, precise detection is performed using a spectrometer (for identifying the chemical composition of large impurities) or a linear camera (for identifying the microscopic features of small impurities). This enables accurate identification of impurities of different types and particle sizes. A secondary detection and rejection component is installed on the lower conveyor belt to further purify the material after the initial sorting. This double screening significantly reduces the impurity residue rate, effectively ensuring the purity of industrial silicon and meeting the stringent requirements for raw material purity in high-end fields. At the same time, it integrates intelligent control systems such as visual inspection, spectral analysis, hydraulic drive, and electric control to achieve fully automated operation from material feeding, dispersion, detection, grading and rejection to finished product export. No manual intervention is required, effectively avoiding errors caused by human factors. It can automatically match the optimal rejection method based on the impurity coordinates, particle size, and type, with rapid response and accurate decision-making, reducing the false rejection rate of high-quality materials.

[0017] In the above scheme, a first hydraulic rod and a gear and rack transmission mechanism are used to link the spectrometer and a linear camera. Based on the detection results of the spectrometer and the linear camera, impurities are removed. A first high-pressure nozzle is used to remove fine particulate impurities, while an electric gripper is used to precisely grasp large particulate impurities. This targeted removal method adapts to different impurity characteristics, has a fast removal speed and strong targeting, and can meet the detection needs of industrial silicon materials with different particle sizes and forms. It flexibly responds to the removal needs of impurities of different particle sizes, achieving thorough removal of fine impurities and stable grasping of large particulate impurities. It avoids the limitations of a single removal method. At the same time, the double-layer structure enables continuous graded processing of materials without downtime. Compared with traditional single-layer screening devices, it greatly improves production efficiency and can meet the needs of mass production.

[0018] In the above solution, high-pressure air jets from various duckbill-shaped nozzles clean dust from the inner walls of the first and second protective covers and the surface of the detection components in real time. This prevents dust accumulation from affecting detection accuracy, extends the continuous operating time of the equipment, and reduces the frequency of downtime for cleaning. Furthermore, the high-pressure nozzles are sealed and protected by protective plates and buffer pads to reduce dust entering the nozzles, thereby reducing the equipment failure rate and significantly lowering maintenance costs. The upper conveyor belt targets fine impurities, improving the detection accuracy of visual inspection and greatly reducing the detection error rate. Attached Figure Description

At the same time, impurities are introduced into the discharge pipe through the collection pipe and then discharged through the discharge pipe. A first detection component 5 is provided on one side of the upper first protective cover 14. The first detection component 5 is used for The material on the upper conveyor belt 13 is inspected.

[0023] like Figures 3 to 11As shown, the first detection component 5 includes a first rotating shaft 501, which is rotatably connected to the inner wall of the upper gantry 3. The first rotating shaft 501 has a hexagonal prism structure in the middle and cylindrical sides. The angle of each side of the first rotating shaft 501 is fixed, which facilitates precise angle adjustment. The two ends of the first rotating shaft 501 pass through the outer wall of the upper gantry 3 and are fixedly connected to first gears 502. One side of each of the two first gears 502 is meshed with a first rack 506. The outer walls of each of the two first racks 506 are slidably connected to first slide rails. The two first slide rails are respectively connected to the upper gantry 3. The outer wall is fixedly connected, and the bottom ends of the two first racks 506 are fixedly connected to the first hydraulic rods 507. The two first hydraulic rods 507 are respectively fixedly connected to the outer wall of the upper gantry frame 3. The first detection component 5 also includes two first guide rails 505, which are respectively installed on the adjacent outer walls of the first rotating shaft 501. A spectrometer 503 is installed on the outer side of one first guide rail 505. The spectrometer 503 distinguishes impurities by measuring the wavelengths of different elements inside the material. A linear camera 504 is installed on the outer side of the other first guide rail 505. By scanning, the minute features of the material are converted into pixel signals with sufficient contrast and signal-to-noise ratio in the digital image, which are then identified by the algorithm, thereby intelligently distinguishing fine impurities. The cleaning component 8 includes several first duckbill-shaped nozzles 801, which are arranged inside the upper gantry 3. The first duckbill-shaped nozzles 801 are connected to a U-shaped tube 802, and the bottom end of the U-shaped tube 802 is connected to several second duckbill-shaped nozzles 803. The first duckbill-shaped nozzles 801 and the second duckbill-shaped nozzles 803 face opposite directions and are all slightly tilted upwards. The dust on the bottom surfaces of the upper first protective cover 14 and the second protective cover 15 is cleaned. The other end of the U-shaped tube 802 is connected to the first connecting tube 804. The other end of the first connecting tube 804 passes through the outer wall of the upper gantry 3 and is connected to the first air guide tube 603. One-way valves are installed on both the first air guide tube 603 and the first connecting tube 804 to control the gas introduction and prevent backflow. At the same time, a pulse valve is installed on the first air guide tube 603 to facilitate the conversion of high-pressure gas into high-pressure pulse gas, so that the high-pressure pulse gas can be sprayed out through the first high-pressure nozzle 604 to remove impurities.

[0024] like Figures 3 to 10As shown, the first rejection assembly 6 includes two second racks 601, which are fixedly connected to the output end of the first hydraulic rod 507. The outer walls of both second racks 601 are slidably connected to second slide rails, which are fixedly connected to the outer walls of the upper gantry 3. Protective sleeves on both sides of the upper gantry 3 protect the first rejection assembly 6 and the second rejection assembly 7. A second gear 605 is meshed with one outer wall of each of the two second racks 601. A second rotating shaft is fixedly connected to the center of each of the two second gears 605, and the two second rotating shafts are rotatably connected to the outer walls of the upper gantry 3. The first rejection assembly 6 also includes a connecting rod 602, which is fixedly connected to the two second racks 601. Between the two racks 601, the two ends of the connecting rod 602 pass through the outer wall of the upper gantry 3 and are slidably connected thereto. The bottom end of the connecting rod 602 is fixedly connected to the first air guide pipe 603. A portion of the first air guide pipe 603 is connected to a corrugated pipe for easy adjustment according to the movement of the connecting rod 602. One side of the first air guide pipe 603 is internally connected to several first high-pressure nozzles 604. Each first high-pressure nozzle 604 is equipped with an exhaust valve for easy control of a single first high-pressure nozzle 604. The second rejection assembly 7 includes two third racks 701. The two third racks 701 are respectively meshed and connected to the other outer wall of the second gear 605. The second rack 601 and the third rack 701 are respectively arranged in the second gear 605. The two sides of the rack are arranged so that the second rack 601 and the third rack 701 move in opposite directions. The outer sides of the two third racks 701 are slidably connected to third slide rails, both of which are fixedly connected to the outer wall of the upper gantry 3. A connecting seat 702 is fixedly connected between the two third racks 701. Both ends of the connecting seat 702 penetrate the outer wall of the upper gantry 3 and are slidably connected thereto. The second rejection assembly 7 also includes a protective plate 703, which is hinged to one side of the connecting seat 702. The bottom end of the protective plate 703 is inclined and perpendicular to the orientation of the first high-pressure nozzle 604. A buffer pad 704 is used to isolate the protective plate 703 and the first high-pressure nozzle 604, facilitating the adjustment of the nozzle position of the first high-pressure nozzle 604. For sealing, the torsion spring 705 applies a certain pressure to the protective plate 703, thereby putting the protective plate 703 in a pre-tightened state, which facilitates the sealing performance of the buffer pad 704. The torsion spring 705 is installed at the hinge between the connecting seat 702 and the protective plate 703. The buffer pad 704 is bonded to the other side of the protective plate 703. The second guide rail 706 is installed on the other side of the connecting seat 702. The second hydraulic rod 707 is installed on the other side of the second guide rail 706. Two miniature hydraulic rods 708 are fixedly connected to the output end of the second hydraulic rod 707. The electric gripper 709 is fixedly connected to the output end of the two miniature hydraulic rods 708. The electric gripper 709 is an existing structure and can be automatically controlled by the terminal system.

[0025] like Figures 4 to 12 As shown, the secondary detection and rejection assembly 9 includes several third duckbill-shaped nozzles 901, all of which are located inside the lower gantry 3. The nozzles of the third duckbill-shaped nozzles 901 are flat and slightly tilted upwards, converting the gas into a fan-shaped air slit to clean the lower first protective cover 14. The other end of each third duckbill-shaped nozzle 901 is connected to a second connecting pipe 902. The other end of the second connecting pipe 902 passes through the lower gantry 3 and is connected to a second air guide pipe 904. A one-way valve is installed on the second air guide pipe 904 for easy gas control. Several second high-pressure nozzles 903 are located inside the lower gantry 3. Each second high-pressure nozzle... Valves are installed on each of the 903 nozzles to facilitate control of a single second high-pressure nozzle 903. The other end of several second high-pressure nozzles 903 is connected to a second air guide pipe 904. The second air guide pipe 904 is fixedly connected to the inner wall of the lower gantry 3. The other end of the second connecting pipe 902 passes through the outer wall of the lower gantry 3 and is connected to the second air guide pipe 904. The other end of the first air guide pipe 603 and the second air guide pipe 904 is connected to a main flow pipe 10. An air inlet valve is installed inside the main flow pipe 10. The other end of the main flow pipe 10 is connected to a high-pressure gas pipe. When gas needs to be introduced, the air inlet valve is opened, thereby diverting the gas to the inside of the first air guide pipe 603 and the second air guide pipe 904 through the main flow pipe 10.

[0026] The working principle of the technical solution provided by this invention is as follows: During operation, the required material is fed into the feeding mechanism 2, which disperses the material and then guides it to the upper conveyor belt 13. The upper conveyor belt 13 transports the material, and when it approaches the end of the belt, the upper first camera 4 detects and records the coordinates of impurities. When larger impurities are detected, the first guide rail 505 at the bottom of the first rotating shaft 501 is activated, driving the spectrometer 503 to move. The spectrometer 503 is then moved by the moving spectrometer. Instrument 503 further distinguishes whether a substance is an impurity by analyzing the energy wavelengths released by elements within the substance at the coordinate position. When an impurity is identified, the second guide rail 706 is driven. Under the drive of the second guide rail 706, the electric gripper 709 moves to the corresponding position of the impurity. When the impurity moves below the electric gripper 709, the micro hydraulic rod 708 is activated. The output end of the micro hydraulic rod 708 drives the electric gripper 709 to move downward, so that the electric gripper 709 moves above the impurity. The electric gripper 709 is then activated again, and the electric gripper... 709 grips the impurity, then activates the micro hydraulic rod 708. The output of the micro hydraulic rod 708 drives the electric gripper 709 to move upwards. Simultaneously, the second hydraulic rod 707 and the first guide rail 505 are activated, driving the electric gripper 709 to move to the upper end of the opening of the discharge mechanism 11. The electric gripper 709 is then activated again to place the impurity into the discharge mechanism 11. Finally, the electric gripper 709 is driven back to its original position for the next removal, completing the removal process. After removal, the material is guided to the lower conveyor belt 13 through the upper material guide tube 12. The material is then transported by the lower conveyor belt 13. When the material is transported to near the end of the lower conveyor belt 13, the lower first camera 4 is used to further detect impurities inside the material. If there are a small amount of impurities, the lower first camera 4 records the coordinate position of the impurities. Then, the exhaust valve on the second high-pressure nozzle 903 at the corresponding position is opened, and the impurities are blown into the discharge mechanism 11 through the second high-pressure nozzle 903 at that position.

[0027] Furthermore, when the upper first camera 4 detects a small, indistinguishable impurity in the material at a certain location, the first hydraulic rod 507 is activated. The output end of the first hydraulic rod 507 drives the first rack 506 to move downwards, while the first rack 506 drives the first gear 502 to rotate. The first gear 502 rotates to a fixed angle, which in turn drives the first rotating shaft 501 to rotate to a fixed angle, causing the lens of the linear camera 504 to face downwards. The first guide rail 505 then performs a secondary detection of the impurity at the coordinate position by the linear camera 504. The terminal system then automatically analyzes the impurity, and when the terminal system determines it to be an impurity, it removes it.

[0028] Furthermore, when the first hydraulic rod 507 drives the first rack 506 to move downward, it simultaneously drives the second rack 601 to move downward. The second rack 601 drives the connecting rod 602 to move downward, which in turn drives the first air guide pipe 603 to move downward. This causes the first high-pressure nozzle 604 to move downward, reaching the jet height. When the second rack 601 moves downward, it drives the second gear 605 to rotate, which in turn drives the third rack 701 to move upward. Simultaneously, the third rack 701 drives the connecting seat 702 to move upward, which in turn drives the electric gripper 709 and the protective plate 703 to move upward, thereby opening the first high-pressure nozzle 604. At this point, based on the impurity position determined by the terminal, the first high-pressure nozzle 604 corresponding to the impurity position is opened, and the impurity is blown into the discharge mechanism 11 through the first high-pressure nozzle 604 in that direction.

[0029] Furthermore, when it is necessary to restore the normal detection state, the first hydraulic rod 507 is activated. The output end of the first hydraulic rod 507 drives the first rack 506 to move upwards. Simultaneously, the first rack 506 drives the first gear 502 to rotate in the opposite direction by a fixed angle. The first gear 502 then drives the first rotating shaft 501 to rotate in the opposite direction by a fixed angle, causing the spectrometer 503 to face downwards. At the same time, the output end of the first hydraulic rod 507 drives the second rack 601 to move upwards. The second rack 601 drives the connecting rod 602 to move upwards, which in turn drives the first air guide tube 603 to move upwards. This, in turn, drives the first high-pressure nozzle 604 to move upwards, causing the first high-pressure nozzle 604 to move upwards. The device moves to its original position, and at the same time, the second rack 601 drives the second gear 605 to rotate. The second gear 605 drives the third rack 701 to move downward, and the third rack 701 drives the connecting seat 702 to move downward. The connecting seat 702 drives the electric gripper 709 to move downward to its original position. At the same time, the connecting seat 702 drives the protective plate 703 to move downward and contact the first high-pressure nozzle 604 that is moving upward. At the same time, the bottom end of the protective plate 703 is squeezed by the first high-pressure nozzle 604 and deflected to the other side. When both the protective plate 703 and the first high-pressure nozzle 604 have moved to their original positions, the buffer pad 704 on the protective plate 703 seals the first high-pressure nozzle 604.

[0030] Furthermore, when the upper first camera 4 and the spectrometer 503 or linear camera 504 are working, the one-way valve on the first connecting pipe 804 is opened, allowing high-pressure gas to enter the interior of the first duckbill nozzle 801 and the second duckbill nozzle 803 through the two pipes on both sides of the U-shaped pipe 802, and then clean the surface of the first protective cover 14 through the high-pressure air gap blown out by the first duckbill nozzle 801, thereby improving the clarity of the first camera 4. At the same time, the surface of the second protective cover 15 is cleaned through the high-pressure air gap blown out by the second duckbill nozzle 803, thereby improving the clarity of the spectrometer 503 or linear camera 504.
