Embodiment

[0022] As Figure 1 、 Figure 2 、 Figure 3 And Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the distance between gears is fixed to each other, there is no adjusting device, and it can only clean single-crystal silicon square bars of the same type, resulting in low versatility of the equipment. At the same time, the single-crystal silicon square bars produced by the factory have various specifications, and a single-crystal silicon square bar of one specification is only applicable to a set of cleaning equipment, which easily leads to an increase in production costs. The general idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a surface cleaning device for a single-crystalline silicon square rod, which includes a bottom plate 1 and a square rod body 11. A first connecting plate 12 is fixedly installed at the top end of the bottom plate 1, and two second connecting plates 13 are fixedly installed at the top end of the first connecting plate 12. Through the first spray heads 17 installed inside the two second connecting plates 13 and the second spray heads 19 installed at the top end of the first connecting plate 12, the cleaning agent is connected into the inside of the support plate 14 through the connecting pipe 16. Through the conveying pipes installed on both sides of the support plate 14, the cleaning agent is conveyed into the inside of the first spray heads 17 and the second spray heads 19. The surface of the single-crystalline silicon square rod is rinsed by the first spray heads 17 and the second spray heads 19. At least two first spray heads 17 are fixedly installed on the inner side wall of each second connecting plate 13. Two support plates 14 are fixedly installed at the top end of the first connecting plate 12 between the two second connecting plates 13. At least two second spray heads 19 are fixedly installed at the top end of the first connecting plate 12. A driving roller 21 is rotatably installed at the top end of the first connecting plate 12.

[0024] Two regulating valves 15 are rotatably installed at the side end of each support plate 14. A connecting pipe 16 is rotatably installed at the side end of each regulating valve 15. A fixing frame 22 is slidably installed inside each support plate 14. Two positioning rods 25 are rotatably installed at the side end of each fixing frame 22. Two first driving rods 24 are fixedly installed at the side end of each fixing frame 22. At least two positioning grooves 23 are formed at the top end of each fixing frame 22. A second driving rod 27 is fixedly installed at the top end of each support plate 14. By continuously compressing the second driving rod 27, the L-shaped plate 26 continues to move downward. The telescopic rod 28 is acted on by the L-shaped plate 26, and the top end of the telescopic rod 28 is pushed downward, so that the end of the telescopic rod 28 pushes the regulating valve 15 to rotate at the side end of the connecting pipe 16. The two regulating valves 15 rotate in opposite directions to each other to adjust the space inside the regulating valve 15. An L-shaped plate 26 is fixedly installed at the top end of each second driving rod 27. Two telescopic rods 28 are rotatably installed at the side end of each second driving rod 27. At least two hydraulic rods 18 are fixedly installed at the top end of the first connecting plate 12.

[0025] Working principle:

[0026] First step, during use, by inserting the single-crystal silicon square rod into the interior of the second connecting plate 13, the outer side of the single-crystal silicon square rod is in contact with the driving roller 21 and the positioning rod 25. The single-crystal silicon square rod is positioned by the fixing frame 22 cooperating with the second connecting plate 13. By driving the driving roller 21 to rotate, the driving roller 21 makes frictional contact with the bottom end of the single-crystal silicon square rod, pushing the single-crystal silicon square rod to slide inside the second connecting plate 13. Through the first nozzles 17 installed inside the two second connecting plates 13 and the second nozzles 19 installed at the top of the first connecting plate 12, the cleaning agent is connected to the interior of the support plate 14 through the connecting pipe 16. Through the conveying pipes installed on both sides of the support plate 14, the cleaning agent is conveyed into the first nozzles 17 and the second nozzles 19. The surfaces of the single-crystal silicon square rod are rinsed by the first nozzles 17 and the second nozzles 19. By controlling the telescopic movement of the second driving rod 27, the second driving rod 27 is stretched upward at the top of the support plate 14. The top end of the second driving rod 27 drives the L-shaped plate 26 to move upward, causing the end of the L-shaped plate 26 to leave the interior of the positioning groove 23. At the same time, the top end of the second driving rod 27 drives the top end of the telescopic rod 28 to move upward. Since the telescopic rod 28 is a telescopic structure, the telescopic rod 28 is subjected to the pulling force of the second driving rod 27 and first undergoes telescopic movement. The acting force received by the end of the telescopic rod 28 is weakened and does not drive the regulating valve 15 to rotate and move. By driving the first driving rod 24, the first driving rod 24 pushes the fixing frame 22, causing the fixing frame 22 to slide horizontally at the side end of the support plate 14, driving the positioning rod 25 to move, and adjusting the distance between the two fixing frames 22. At the same time, by controlling the hydraulic rod 18, the hydraulic rod 18 is telescoped at the top of the first connecting plate 12, causing the hydraulic rod 18 to push the second connecting plate 13, and the second connecting plate 13 moves upward at the top of the first connecting plate 12. Cooperating with the fixing frame 22, single-crystal silicon square rods of various specifications can be positioned and cleaned, increasing the versatility of the equipment and reducing the production cost.

[0027] Step 2: Position and clean single-crystalline silicon square bars of different specifications by adjusting the position of the positioning rod 25 and the second connecting plate 13. At the same time, drive the second driving rod 27 to extend and retract downward, so that the second driving rod 27 drives the L-shaped plate 26 to move downward, and the L-shaped plate 26 is inserted into the positioning groove 23 to fix the position of the fixing frame 22. At the same time, as the L-shaped plate 26 moves downward, the side end of the L-shaped plate 26 pushes the top of the telescopic rod 28, causing the telescopic rod 28 to first retract and reset in the reverse direction. When the inside of the telescopic rod 28 is compressed to the limit position, the L-shaped plate 26 just inserts into the positioning groove 23. By continuously compressing the second driving rod 27, the L-shaped plate 26 continues to move downward. The telescopic rod 28 is subjected to the force of the L-shaped plate 26 and pushes the top of the telescopic rod 28 to move downward, causing the end of the telescopic rod 28 to push the regulating valve 15 to rotate at the side end of the connecting pipe 16. The two regulating valves 15 rotate in opposite directions to adjust the space inside the regulating valve 15 and control the flow rate of the internal cleaning agent. The dosage sprayed by the first nozzle 17 and the second nozzle 19 can be controlled according to the size of the single-crystalline silicon square bar to prevent waste.

[0028] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. The obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
