Multiple air outlet pipes are arranged side by side, and both ends of the multiple air outlet pipes are respectively connected to the air inlet pipe 20. In this embodiment: the air inlet pipe 20 is annular, and two air inlets 200 are opened on the annular air inlet pipe 200.
[0028] In one implementation of the present embodiment: the wind knife unit also includes a bottom plate 22, and the annular air inlet pipe 20 surrounds the bottom plate 22. The bottom plate 22 and the air inlet pipe 20 together form a liquid collection tray for collecting water droplets blown off by the air outlet pipe. A plurality of drainage holes 220 are opened on the bottom plate 22 to form a liquid leakage tray. The water droplets collected on the bottom plate 22 can be discharged through the drainage holes 220.
[0029] In another embodiment of the present invention, the wind knife unit further comprises a liquid leakage tray, on which the water droplets blown off by the air outlet pipe fall. The liquid leakage tray comprises a bottom plate 22 and an edge portion, wherein a plurality of drainage holes 220 are provided on the bottom plate 22; and the edge portion forms a ring-shaped air inlet pipe 20.
[0030] The air outlet pipe includes a first air outlet pipe section 210 and a second air outlet pipe section 211. One end of the first air outlet pipe section 210 is connected to the air inlet pipe 20, the other end of the first air outlet pipe section 210 extends upward and is connected to one end of the second air outlet pipe section 211, the other end of the second air outlet pipe section 211 extends downward and is connected to the air inlet pipe 20, and the first air outlet pipe section 210 is closer to the flower basket entry area 10. In the figure: the angles between the first air outlet pipe section 210, the second air outlet pipe section 211 and the surface where the air inlet pipe 20 is located are all less than 90°, so that the air inlet pipe 20 and the air outlet pipe form a triangle on a projection surface.
[0031] The second air outlet pipe section 211 is provided with a plurality of air outlets 2110 along its length, and a purge area is formed between two adjacent second air outlet pipe sections 211, and the plurality of purge areas can purge a plurality of silicon wafers at the same time. Preferably, the second air outlet pipe section 211 is provided with air outlets 2110 on both sides of the purge area, and the silicon wafers are purged and dried from both sides at the same time.
[0032] In one implementation of this embodiment: the second air outlet pipe section 211 includes a main pipe section 2111 and an air knife section. The cross section of the main pipe section 2111 is square; the air knife section includes two strip sheets 2112, one side of the two strip sheets 2112 is butted, and the other side of the two strip sheets 2112 is connected to the two sides of a corner of the square main pipe section 2111, and an air outlet gap 2113 is formed between the two strip sheets 2112, and the air outlet gap 2113 is connected to the main pipe section 2111, and the air outlet 2110 is opened on the two strip sheets 2112, such as Figure 4 , 5 The warm air passing through the main pipe section 2111 enters the suddenly narrowed air outlet gap 2113, and the pressure increases, so that it is ejected from the air outlet 2110 under pressure, forming a wind knife to purge and dry the silicon wafer.
[0033] The working process of this embodiment is described in detail below:
[0034] Before drying, first turn on the wind knife unit 2, and the warm air is discharged through the air inlet pipe 20, the first air outlet pipe section 210, the second air outlet pipe section 211, and the air outlet 2110 to preheat the tank body 1 and increase the temperature inside the tank body 1; the flower basket loaded with silicon wafers enters the flower basket entry interval 10 and slowly advances to the first wind knife unit 2. Specifically: the silicon wafer first passes through the first air outlet pipe section 210 of the air outlet pipe, and then enters the second air outlet pipe section 211. In the purge area of the second air outlet pipe section 211, the second air outlet pipe section 211 descends from high to low, and the water on the surface of the silicon wafer is swept downward and dried; after completing the purge of the first wind knife unit 2, it immediately enters the second wind knife unit 2, and repeats this process. After completing the purge of multiple wind knife units 2, it enters the flower basket removal interval 11 to end the drying, thereby shortening the drying time of the drying position and improving the production efficiency per unit time.
