[0029] Research has revealed limitations in existing drying air knife mechanisms. They cannot flexibly adjust the airflow of the upper and lower air knife components. For silicon wafers of different sizes, airflow control often requires adjusting the power of different fans. This not only necessitates configuring independent fans for the upper and lower air knives, increasing hardware costs and equipment complexity, but also necessitates repeated adjustments of fan power to prevent wafer vibration during drying when adjusting airflow for various silicon wafers, thus increasing system control costs.
[0030] Based on the above research, the present disclosure provides a drying air knife mechanism and cleaning equipment. By setting an air volume regulating component 400, the air volume of the upper air knife assembly 200 or the lower air knife assembly 300 can be independently adjusted using only one fan 100. This avoids configuring separate fans 100 for the upper and lower air knives, reduces equipment cost and structural complexity, and improves adaptability and operational flexibility for silicon wafers 600 of different sizes. It also prevents the silicon wafers 600 from shaking during the drying process, thereby preventing the silicon wafers 600 from cracking.
[0031] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.
[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0033] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0034] Please see Figure 1 and Figure 2 At least one embodiment provides a drying air knife mechanism, including: a fan 100; an upper air knife assembly 200, which is connected to the air outlet pipe of the fan 100 through a corresponding air duct 110; and a lower air knife assembly 300, which is connected to the air outlet pipe of the fan 100 through a corresponding air duct 110; wherein the upper air knife assembly 200 and the lower air knife assembly 300 are arranged opposite to each other; an air volume regulating component 400 is provided on the air duct 110 connected to the upper air knife assembly 200 and / or the lower air knife assembly 300; and the air volume regulating component 400 is used to adjust the air volume of the corresponding upper air knife assembly 200 or the lower air knife assembly 300.
[0035] By setting the air volume regulating component 400, the air volume of the upper air knife assembly 200 or the lower air knife assembly 300 can be independently adjusted using only one fan 100. This avoids configuring separate fans 100 for the upper and lower air knives, reduces equipment cost and structural complexity, and improves adaptability and operational flexibility for silicon wafers 600 of different sizes. It also prevents the silicon wafers 600 from shaking during the drying process, thereby preventing the silicon wafers 600 from cracking.
[0036] Please see Figure 2 The air volume regulating component 400 includes: an regulating column 410 having a cavity therein, wherein the cavity is connected to a corresponding air duct 110; an regulating plug 420 that passes through the regulating column 410 and extends into the cavity; and an regulating hammer 430 that is disposed in the cavity and connected to one end of the regulating plug 420 that extends into the cavity.
[0037] By adjusting the cross-sectional area of the air duct 110 through the hammer head 430, the air volume of the upper air knife assembly 200 and the lower air knife assembly 300 can be changed simultaneously, so that the silicon wafer 600 can be transported smoothly and the silicon wafer 600 can be prevented from shaking.
[0038] Please continue reading. Figure 2 The adjusting bolt 420 includes an adjusting head 421 and an adjusting screw 422; the top of the adjusting column 410 is provided with an adjusting hole 411; one end of the adjusting screw 422 passes through the adjusting hole 411 and is connected to the adjusting hammer head 430, and the other end is connected to the adjusting head 421; the adjusting screw 422 is threadedly connected to the adjusting hole 411.
[0039] Specifically, the threaded transmission mechanism allows the operator to control the position of the adjusting hammer 430 in the cavity by rotating the adjusting head 421, which facilitates manual adjustment and reduces the need for a control system.

[0041] The structural schematic diagram of the upper air knife assembly 200 is shown in Figure 4.
[0042] Specifically, the number of top air blowing plates 230 is N; and N≥3; wherein, the airflow direction of the first air blowing holes 231 of the top air blowing plates 230 located at both ends is perpendicular to the external silicon wafer 600, and the airflow direction of the first air blowing holes 231 of the remaining top air blowing plates 230 is set at an acute angle to the silicon wafer 600, such as... Figure 3 As shown by the dashed line.
[0043] The vertical air vents 231 at both ends can act as a "constraint" or "edge press" to prevent the silicon wafer 600 from shifting or jumping under high-speed airflow; while the inclined air vents 231 in the middle can form a "peeling" effect, more effectively blowing away water droplets on the surface of the silicon wafer 600, significantly improving drying efficiency and stability, and further avoiding the problem of silicon wafer 600 shaking.
[0044] Please continue reading. Figure 2 and Figure 3 The lower air knife assembly 300 includes: a second air inlet box 310, the bottom of which is provided with a second air inlet hole 320 communicating with the corresponding air duct 110; at least one bottom air blowing plate 330 is provided at intervals on the bottom surface of the second air inlet box 310; and a plurality of second air blowing holes 331 are provided at intervals on the bottom surface of the bottom air blowing plate 330.
[0045] Specifically, the airflow direction of the second air hole 331 of the bottom air blowing plate 330 is set at an acute angle to the silicon wafer 600.

[0047] By setting the air volume regulating component 400, the air volume of the upper air knife assembly 200 or the lower air knife assembly 300 can be independently adjusted using only one fan 100. This avoids configuring separate fans 100 for the upper and lower air knives, reduces equipment cost and structural complexity, and improves adaptability and operational flexibility for silicon wafers 600 of different sizes. It also prevents the silicon wafers 600 from shaking during the drying process, thereby preventing the silicon wafers 600 from cracking.
[0048] The air volume regulating component 400 includes: an regulating column 410 having a cavity therein, wherein the cavity is connected to a corresponding air duct 110; an regulating plug 420 that passes through the regulating column 410 and extends into the cavity; and an regulating hammer 430 that is disposed in the cavity and connected to one end of the regulating plug 420 that extends into the cavity.
[0049] Please see Figure 6 At least one embodiment also provides a cleaning device, including: a cleaning device body 500 and a drying air knife mechanism as described above disposed in the discharge section of the cleaning device; wherein, the cleaning device body 500 includes a conveying mechanism 510; the upper air knife assembly 200 and the lower air knife assembly 300 are respectively disposed on the upper and lower sides of the conveying mechanism 510.

The upper air knife assembly 200 and the lower air knife assembly 300 are arranged opposite to each other. An air volume regulating component 400 is provided on the air duct 110 connected to the upper air knife assembly 200 or the lower air knife assembly 300. The air volume regulating component 400 is used to adjust the air volume of the corresponding upper air knife assembly 200 or lower air knife assembly 300. By setting the air volume regulating component 400, the air volume of the upper air knife assembly 200 or the lower air knife assembly 300 can be independently adjusted using only one fan 100.
