[0022] Please refer to Figures 1 - 4As shown in the figure, the purpose of this embodiment is to provide a silicon raw material cleaning device, including a cleaning table 1. A cleaning tank 2 is arranged at the bottom of the cleaning table 1. The cleaning tank 2 is divided into a pickling chamber 3 and a water bath chamber 4 by a partition board. Valves 5 are arranged at the bottoms of the pickling chamber 3 and the water bath chamber 4. A pair of fixed plates 6 are symmetrically and fixedly connected to the top of the cleaning table 1. A cross plate 7 is installed between the pair of fixed plates 6. A storage box 8 for placing silicon materials is installed at the bottom of the cross plate 7. Flow guiding holes 9 for the solution to enter the inside of the storage box 8 are opened on the four sides and the bottom of the storage box 8. A sliding groove 10 for the up and down movement of the cross plate 7 is opened on each of the pair of fixed plates 6. A slider 11 is slidably connected inside the sliding groove 10. One end of the cross plate 7 is fixedly connected to the outside of one of the sliders 11. The other end of the cross plate 7 penetrates through the other slider 11 and extends to the outside of the fixed plate 6. An electric push rod 12 is fixedly connected to the top of the cleaning table 1. The output end of the electric push rod 12 is fixedly connected to the bottom of the cross plate 7 located outside the fixed plate 6. A groove 13 is opened on the top of the cross plate 7. A pair of reciprocating lead screws 14 are symmetrically and rotatably connected inside the groove 13. A moving block 15 is connected to the nut pairs on the outside of the pair of reciprocating lead screws 14. One end of the pair of reciprocating lead screws 14 extends to the outside of one side of the cross plate 7 and is fixedly connected to a first sprocket 16. The pair of first sprockets 16 are drivingly connected by a first chain 17. A first servo motor 18 coaxially connected to one of the reciprocating lead screws 14 is fixedly connected to the outside of one side of the cross plate 7. A rotating cylinder 19 is rotatably connected through the top of the moving block 15. A driven gear 20 is fixedly connected to the outside of the rotating cylinder 19 located on the moving block 15. A plurality of connecting rods 21 are fixedly connected to the outside of the bottom of the rotating cylinder 19. The connecting rods 21 are fixedly connected to the top of the storage box 8. A transmission shaft 22 is fixedly connected to the top of the moving block 15. A transmission gear 23 meshing with the driven gear 20 is fixedly connected to the outside of the transmission shaft 22. A second servo motor 24 coaxially connected to the transmission shaft 22 is fixedly connected above the moving block 15. Cutting fluid, metal ions, fingerprints, and attached impurities remain on the surface of the edge material during the processing and need to be cleaned. Currently, the commonly used automatic edge material cleaning equipment uses strong acid to remove impurities on the surface of the edge material and then cleans the edge material. However, for the existing automatic cleaning equipment, when removing impurities from the edge material, most use the soaking method. If the number of edge materials is too large and the density is too small, the internal edge materials cannot effectively remove impurities, which will affect subsequent use. Before cleaning, first send the acidic solution and the aqueous solution into the pickling chamber 3 and the water bath chamber 4 respectively through the valve 5, and then place the edge material into the storage box 8. At this time, turn on the first servo motor 18 to drive the first sprocket 16 and the first chain 17 to drive, and drive the pair of reciprocating lead screws 14 to rotate synchronously, so that the moving block 15 located on the pair of reciprocating lead screws 14 moves above the pickling chamber 3, and then turn on the electric push rod 12 to drive the cross plate 7 to move down until the edge material is completely immersed in the pickling solution. Since the rotating shaft 26, the rotating cylinder 19, and the storage box 8 are all made of ceramic materials and do not react with the acidic solution, the impurities on the edge material can be removed. Turn on the second servo motor 24 to drive the transmission shaft 22 to rotate,Because the transmission gear 23 on the transmission shaft 22 is meshed with the driven gear 20 on the outside of the rotating drum 19, the rotation of the rotating drum 19 can make the storage box 8 rotate in the pickling solution, so that the solution can flow, so that the accumulated edge materials can be better removed of impurities and cleaned, and the cleaning effect of the silicon material is improved. After the edge materials are free of impurities, the electric push rod 12 and the first servo motor 18 drive the storage box 8 to move to the water bath 4 to complete the cleaning, and the rotation of the rotating drum 19 allows the edge materials to be dehydrated by centrifugal force, which reduces the processing process and improves the work efficiency.
[0023] See also Figures 1 - 4 As shown, the purpose of this embodiment is that a plurality of limit blocks 25 are fixedly connected inside the rotating cylinder 19, and a rotating shaft 26 that rotates in the opposite direction to the rotating cylinder 19 is rotatably connected to the middle of the limit block 25. A second sprocket 27 is fixedly connected to the top of the rotating shaft 26 and the outside of the transmission shaft 22. A pair of second sprockets 27 are connected by a second chain 28. The bottom end of the rotating shaft 26 extends to the bottom end of the storage box 8. A rotating plate 29 for moving the silicon material is fixedly connected to the outside of the bottom end of the rotating shaft 26. In order to better remove impurities and clean the edge material, by A rotating shaft 26 is arranged in the middle, so that when the second servo motor 24 drives the second sprocket 27 and the second chain 28 to transmit, the rotating shaft 26 can be driven to rotate inside the rotating cylinder 19. Because the transmission directions of the gears and the sprockets are opposite, when the storage box 8 rotates in the solution, the rotating plate 29 at the bottom of the rotating shaft 26 can be driven to rotate in the opposite direction at the same time, and the accumulated scraps can be moved, so that the accumulated scraps inside can be turned to the outside under the movement, so that the scraps can be completely and evenly removed of impurities or cleaned by the solution, thereby further improving the overall cleaning effect.
[0024] Working principle: Before cleaning, the acidic solution and the aqueous solution are respectively fed into the pickling chamber 3 and the water bath chamber 4 through the valve 5, and then the edge materials are placed inside the storage box 8. At this time, the first servo motor 18 is started to drive the transmission of the first sprocket 16 and the first chain 17, and drive a pair of reciprocating lead screws 14 to rotate synchronously, so that the moving blocks 15 located on the pair of reciprocating lead screws 14 move above the pickling chamber 3. Then, the electric push rod 12 is started to drive the cross plate 7 to move down until the edge materials are completely immersed in the pickling solution. Since the rotating shaft 26, the rotating cylinder 19 and the storage box 8 are all made of ceramic materials and do not react with the acidic solution, impurities can be removed from the edge materials. At this time, the second servo motor 24 is started to drive the transmission shaft 22 to rotate. Since the transmission gear 23 on the transmission shaft 22 is meshed and connected with the driven gear 20 outside the rotating cylinder 19, the rotation of the rotating cylinder 19 can make the storage box 8 rotate in the pickling solution, so that the solution can flow, and the edge materials piled up together can be better removed of impurities and cleaned, improving the cleaning effect of the silicon materials. When the impurities are removed from the edge materials, the storage box 8 is driven by the electric push rod 12 and the first servo motor 18 to move into the water bath chamber 4 to complete the cleaning. Moreover, the rotation of the rotating cylinder 19 enables the edge materials to achieve the water removal effect through centrifugal force, reducing the processing flow and improving the work efficiency. In order to enable the edge materials to be better removed of impurities and cleaned, by arranging the rotating shaft 26 inside the rotating cylinder 19, when the second servo motor 24 drives the transmission of the second sprocket 27 and the second chain 28, the rotating shaft 26 can be driven to rotate inside the rotating cylinder 19. Since the directions of conduction of the gear and the sprocket are opposite, when the storage box 8 rotates in the solution, the rotating plate 29 at the bottom end of the rotating shaft 26 can be driven to rotate in the opposite direction, and the piled-up edge materials are stirred, so that the edge materials piled up inside are turned over to the outside under the stirring, enabling the edge materials to be completely and evenly removed of impurities or cleaned by the solution, further improving the overall cleaning effect.
