Description

Technical Field

[0001] The utility model relates to the technical field of silicon wafer production, in particular to a blowing device for a silicon wafer flower basket. Background Art

[0002] Photovoltaic power generation is one of the primary ways to utilize solar energy. Due to its clean, safe, convenient, and efficient characteristics, it has become an emerging industry that is attracting widespread attention and is being developed globally. Therefore, in-depth research and utilization of solar energy resources are crucial for alleviating resource crises and improving the ecological environment. Silicon wafers are an essential component of photovoltaic power generation.

[0003] Currently, silicon wafer cleaning is an important production process before silicon wafer manufacturing and testing. High decontamination and drying capabilities are key indicators of silicon wafer cleaning capabilities. When existing silicon wafers are cleaned in a cleaning tank, they are usually transferred between multiple cleaning tanks and drying ovens with the help of silicon wafer baskets. After the silicon wafers are cleaned in the cleaning tank, the silicon wafer baskets are controlled to be lifted upward from the cleaning tank. At this time, there will be a large area of cleaning liquid residue on the silicon wafer baskets and the side end surfaces of the silicon wafers. Therefore, the silicon wafer baskets and silicon wafers need to be drained. However, there are still a large number of water droplets on the surface of the silicon wafers after draining. Directly transferring the silicon wafers to the drying oven for drying at this time will lead to problems such as low drying efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a blowing device for a silicon wafer flower basket.

[0005] The utility model is realized through the following technical solutions:

[0006] A blowing device for silicon wafer flower baskets includes a flower basket transfer rack, which is used to place and transfer silicon wafer flower baskets. The flower basket transfer rack is provided with an air knife, and the air outlet of the air knife is directed toward the silicon wafer flower basket placed on the flower basket transfer rack, so as to blow air to the silicon wafer flower basket on the flower basket transfer rack.

[0007] As a further improvement of the present invention, the wind knife is obliquely arranged on the flower basket transfer rack and is located on one side of the silicon wafer flower basket placed on the flower basket transfer rack.

[0008] As a further improvement of the present invention, mounting seats are provided on both sides of the flower basket transfer rack, and the mounting seats include a connecting portion and an inclined portion provided on the lower side of the connecting portion. The distance between the inclined portions on both sides gradually increases from top to bottom, and the air knife is provided at the inner side of the inclined portion so that the air outlet of the air knife faces the cleaning liquid surface of the cleaning tank.

[0009] As a further improvement of the present invention, the flower basket transfer rack includes a transfer beam, a group of vertical mounting plates are provided on the transfer beam, and the mounting seat is provided between the group of vertical mounting plates.

[0010] As a further improvement of the present invention, connecting ends are provided on both sides of the vertical mounting plate, and connecting grooves are provided at both ends of the mounting seat, and the connecting grooves can allow the connecting ends to be embedded along a preset direction.

[0011] As a further improvement of the present invention, the mounting seat can be rotatably arranged between a group of vertical mounting plates to adjust the blowing angle of the wind knife.

[0012] As a further improvement of the present invention, connecting shafts are provided on both sides of the vertical mounting plate, and connecting grooves are provided at both ends of the mounting seat. The connecting shaft can be inserted into the connecting groove along a preset direction, and the connecting shaft and the connecting groove can rotate relative to each other.

In the process of lifting and draining the silicon wafer flower basket, the air knife 2 blows air to the silicon wafer flower basket, thereby blowing the liquid carried by the silicon wafer flower basket and the silicon wafer into the cleaning tank, thereby reducing the amount of liquid carried by the silicon wafer flower basket and the silicon wafer, and accelerating the draining efficiency. In addition, since the air knife 2 blows air to the silicon wafer, it can reduce the water droplets on the surface of the silicon wafer, thereby improving the drying efficiency of the silicon wafer flower basket when it is transferred to the drying box.

[0029] Mounting seats 3 are provided on both sides of the flower basket transfer rack 1, and the mounting seats 3 include a connecting portion 301 and an inclined portion 302 arranged on the lower side of the connecting portion 301. The distance between the inclined portions 302 on both sides gradually increases from top to bottom. The air knife 2 is arranged at the inner side of the inclined portion 302 so that the air outlet of the air knife 2 faces the cleaning liquid surface of the cleaning tank.

[0030] The flower basket transfer rack 1 includes a transfer beam 101 , on which a group of vertical mounting plates 102 are provided, and the mounting seat 3 is provided between the group of vertical mounting plates 102 .

[0032] In addition, in this embodiment, an intermediate air inlet 8 connected to the interior of the wind knife 2 is provided on the inclined portion 302, and air inlets are provided at both ends of the wind knife 2. At the same time, an intermediate air inlet 8 is provided to facilitate the connection of an external fan. It is worth noting that in this embodiment, an intermediate air inlet 8 is provided on the rear side of the wind knife 2, which is connected to its internal air passage. The wind knife 2 in this embodiment has an existing technical structure of the air passage, which will not be described here.

[0033] Example 2, reference Figures 4 and 5 , the embodiments of the present utility model disclose:

[0034] A blowing device for silicon wafer flower baskets includes a flower basket transfer rack 1, which is used to place and transfer silicon wafer flower baskets 1001. Air knives 2 are provided on both sides of the flower basket transfer rack 1. The air knives 2 are directed toward the middle of the flower basket transfer rack 1 to blow air to the silicon wafer flower baskets 1001 on the flower basket transfer rack 1. In this embodiment, the air knives 2 are obliquely arranged on both sides of the flower basket transfer rack 1, and the blowing ports of the air knives 2 are directed toward the silicon wafer flower baskets.

[0035] It is worth noting that the wind knife 2 is an existing structure, which is a product structure purchased on the market, such as the wind knife authorized for disclosure in December 2022 and with publication number CN218120557U. Therefore, the specific structure of the wind knife 2 will not be described here.

[0036] In this embodiment, the flower basket transfer rack 1 is connected to the transport mechanism, and the silicon wafer flower basket is arranged on the flower basket transfer rack 1, and the silicon wafer is arranged on the silicon wafer flower basket, so that the flower basket transfer rack 1 can transfer the silicon wafer flower basket from the cleaning tank to the drying box; and in this embodiment, a lifting device is provided (the lifting device is a structure well known to those skilled in the art and will not be described here) to drive the silicon wafer flower basket to rise and fall; and air knives 2 are provided on both sides of the flower basket transfer rack 1, and the air blowing port of the air knife 2 is inclined downward toward the silicon wafer flower basket. In the process of lifting and draining the silicon wafer flower basket, the air knife 2 blows air to the silicon wafer flower basket, thereby blowing the liquid carried by the silicon wafer flower basket and the silicon wafer into the cleaning tank, thereby reducing the amount of liquid carried by the silicon wafer flower basket and the silicon wafer, and accelerating the draining efficiency. In addition, since the air knife 2 blows air to the silicon wafer, it can reduce the water droplets on the surface of the silicon wafer, thereby improving the drying efficiency of the silicon wafer flower basket when it is transferred to the drying box.
