[0023] The spray assembly 10 includes a spray frame 101 fixedly connected to the lower end of the connecting rod 9. Four grooves 102 are provided below the spray frame 101. Four motors 103 are fixedly connected to the outer wall of the spray frame 101. A rotating shaft 104 is fixedly connected to the output end of each of the four motors 103 and to one end of each of the four grooves 102. A spray shell 105 is fixedly connected to the outer wall of the rotating shaft 104. A spray pipe 106 is fixedly connected to the inner wall of the spray shell 105. A spray head 107 is provided below the spray pipe 106. The spray assembly 10 can cover the surface of the silicon wafer.

[0024] The spray frame 101 is shaped like a cross, with four grooves 102 symmetrically distributed below it. The cross-shaped spray frame 101 raises the coverage area of ​​the spray head 107.

[0025] There are multiple spray heads 107, which are evenly distributed below the spray pipe 106. The multiple spray heads 107 facilitate the even spraying of the cleaning solution onto the silicon wafer surface.

[0026] The output end of the pressure pump 6 is connected to the spray pipe 106 via a hose. The pressure pump 6 facilitates the increase of the cleaning fluid pressure, thereby improving the cleaning effect of the silicon wafer.

[0027] A second motor 701 is fixedly connected to one side of the mounting base 7. The output end of the second motor 701 passes through the connecting rod 9 and is fixedly connected to the connecting rod 9. The second motor 701 facilitates the rotation of the connecting rod 9, thereby changing the angle of the spray frame 101.

[0028] A controller 14 is located on the front side of the cleaning machine body 1, and an operation button 15 is also located on the front side of the cleaning machine body 1. The controller 14 is electrically connected to motor 103, motor 701, pump body 4, and pressurizing pump 6. The controller 14 facilitates operation and control by the staff.

[0029] Four bases 16 are fixedly connected to the lower end of the cleaning machine body 1, and the four bases 16 are arranged symmetrically. The four bases 16 help to improve the stability of the cleaning machine body 1 during operation.

[0030] Working principle: When in use, open the door 2, place the silicon wafer to be cleaned into the cleaning machine body 1, and then close the door 2. At this time, the pump body 4 can be started to draw the cleaning solution from the container tank 3 and deliver it to the pressure pump 6 through the output pipe 5. The pressure pump 6 pressurizes the cleaning solution and delivers it to the spray pipe 106 through the hose. Then, it is evenly sprayed onto the surface of the silicon wafer from the spray head 107 for cleaning. When it is necessary to adjust the spray angle, the motor 701 can be started to drive the connecting rod 9 to move in the tank 8, thereby adjusting the angle of the spray frame 101 so that it is aligned with different areas of the silicon wafer. Secondly, the motor 103 can be started to output the rotating shaft 104 to change the angle of the spray shell 105, thereby slightly changing the spray angle of the spray head 107, so that the cleaning solution evenly covers the surface of the silicon wafer. In addition, the wastewater generated during the cleaning process flows into the drain tank 11, is filtered through the filter screen 12, and is discharged from the cleaning machine body 1 through the drain pipe 13.
