As a carrier for cleaning and drying silicon wafers, the design optimization of the flower basket is of great significance for improving production efficiency and reducing energy consumption costs.

[0003] Currently, during the drying process after silicon wafer cleaning, the liquid on the surface of the silicon wafer may accumulate at the bottom of the basket due to gravity. If the liquid on the bottom of the basket is to be evaporated, the drying temperature needs to be increased and the drying time needs to be extended, which not only increases energy consumption but also affects the drying efficiency.

[0036] Silicon wafers are the core component of solar cells, primarily responsible for converting the energy of photons in sunlight into electrical energy through photoelectric conversion, utilizing the properties of semiconductors. Silicon wafers not only provide the physical basis for solar cells but also directly influence their performance, efficiency, and cost. Therefore, the quality of silicon wafers is one of the key factors in the development of solar cell technology.

[0037] The manufacturing process of solar cell silicon wafers mainly includes the following steps: raw material preparation, silicon ingot growth, silicon ingot processing, silicon wafer polishing, cleaning and inspection, and subsequent processing steps. Among these, the solar cell silicon wafers need to be cleaned to remove the damaged layers and impurities caused by the previous silicon ingot processing and wafer polishing. The quality of cleaning is crucial for ensuring device performance, improving yield, and reducing production costs.

[0038] In the production process of solar cell silicon wafers, the wafer basket, as the main structure supporting the silicon wafers, primarily consists of two end plates and multiple basket rods. The two end plates are spaced apart, and the multiple basket rods connect to the two end plates, thus forming a space to hold the silicon wafers. The wafer basket also includes supporting base rods, plastic trays, or plastic inserts. The basket structure design effectively prevents problems such as wafer slippage, wafer sticking, and liquid contamination, while also protecting the silicon wafers and reducing potential damage during production.

[0039] Currently, trough-type cleaning equipment is commonly used for cleaning solar cell silicon wafers. This equipment typically includes a cleaning tank, control system, transmission system, gas and liquid piping units, and exhaust unit. The trough-type cleaning equipment primarily removes contaminants from the silicon wafer surface by placing the wafers in a specific chemical solution and utilizing chemical reactions or physical actions (such as ultrasonic waves or megasonic waves). The basket, acting as a carrier for the solar cells within the trough-type cleaning equipment, carries the cells through the cleaning and drying processes. Therefore, the cleanliness and drying speed of the basket determine the quality and efficiency of solar cell production.

[0040] Currently, after the baskets and silicon wafers are cleaned, they undergo electrically heated hot air circulation in a tank-type cleaning equipment to raise the temperature inside the tank, causing some of the liquid to evaporate and achieving a certain degree of drying effect. However, during the drying process, the inventors discovered that the liquid on the surface of the silicon wafers slides downwards, causing the liquid to concentrate and adhere below the bottom rod of the basket. To completely dry the liquid, it is necessary to increase the drying temperature and extend the drying time, which seriously affects production efficiency.

[0041] To expedite the removal of liquid from the bottom of the flower basket, the inventors attempted to add absorbent cotton, ensuring it adhered tightly to the basket's bottom and utilizing its absorbent capacity to remove any undried liquid. However, prolonged use or infrequent replacement of the absorbent cotton led to a decrease in its absorbency, causing the liquid inside the cotton to contaminate the flower basket.

[0042] Based on this, this application discloses a flow guiding device, which aims to utilize the electrically heated hot air circulation inside the tank-type cleaning equipment to complete the drying of the silicon wafer and the basket as a whole. Specifically, a flow guiding device is added below the basket, and a flow guiding component in contact with the bottom rod of the basket guides the liquid below the bottom rod away from the bottom rod, thereby reducing the accumulation of liquid below the bottom rod and improving the drying efficiency without changing the drying temperature.

[0043] The technical solution of this application will be further described below with reference to examples and accompanying drawings.

[0044] Please see Figure 1 and Figure 2 , Figure 1 A schematic diagram showing the connection between the flow guiding device 1 and the flower basket body 3. Figure 2 This is a schematic diagram of the overall structure of the flow guiding device 1.

[0045] This application provides a flow guiding device 1, which can be applied in the production process of solar cells, specifically in the silicon wafer drying process of solar cells, to support the basket body 3 while guiding the liquid accumulated on the bottom rod 32 of the basket, thereby improving the drying efficiency.

[0046] Specifically, the basket body 3 may include components such as a top plate 30, a bottom plate 31, and a basket bottom rod 32, which are used for carrying and transporting silicon wafers, as well as protecting the silicon wafers carried by the basket body 3 and reducing damage to the silicon wafer surface.

[0047] In some embodiments, the flow guiding device 1 includes a base 10 and a flow guiding member 11. The base 10 is provided with two support parts 1021, which are spaced apart along a first direction X. The two support parts 1021 are respectively used to support the top plate 30 and the bottom plate 31 of the flower basket. The flow guiding member 11 is disposed on the base 10 and is located between the two support parts 1021 along the first direction X. It is used to connect with the bottom rod 32 of the flower basket to guide the liquid on the bottom rod 32 of the flower basket.

[0048] The top plate 30 and bottom plate 31 of the basket are supported by the bearing part 1021, so that the basket body 3 can be suspended relative to the drying equipment (e.g., the washing tank). At the same time, the guide member 11 is connected to the bottom rod 32 of the basket, so that the guide member 11 can guide the liquid on the bottom rod 32 of the basket to the base 10, avoiding the accumulation of liquid on the bottom rod 32 of the basket, which is beneficial to improving the drying efficiency of the basket body 3 and the silicon wafer.

[0049] Optionally, the base 10 can be a seat structure, a platform structure, or a plate structure, etc.

[0050] In some embodiments, please refer to Figure 1 The base 10 includes a base plate 101 and two support members 102. The two support members 102 are spaced apart on the base plate 101 along the first direction X. Each support member 102 is provided with a bearing portion 1021. The flow guide member 11 is provided on the base plate 101.

[0051] By configuring the base 10, which includes a base plate 101 and a support member 102, and two support parts 1021 disposed on the support member 102, with the two support members 102 spaced apart along the first direction X, the flower basket body 3 can be disposed on the support member 102 along the first direction X. The support member 102 is used to support the top plate 30 and bottom plate 31 of the flower basket. That is, the support member 102 and the base plate 101 can be disposed separately. This separate design makes the structure of the base 10 more stable, better able to bear the weight of the flower basket, and reduces the deformation of the base 10 caused by excessive weight of the flower basket or liquid impact. In addition, the two support members 102 respectively support the top plate 30 and bottom plate 31 of the flower basket. This independent support method can effectively distribute the weight of the flower basket, avoid excessive local stress, and thus help improve the load-bearing capacity and stability of the entire device.

[0052] Optionally, the substrate 101 can be in the shape of a strip, for example, the substrate 101 can be a rectangular plate. Of course, as other examples, the substrate 101 can also be in the shape of a circular plate, or a polygonal plate other than a rectangle, or an irregularly shaped plate, etc.

[0053] Taking the substrate 101 as a rectangular plate as an example, the first direction X can be the length direction of the substrate 101. Thus, the two support members 102 are arranged along the first direction X, so that the two support members 102 have sufficient spacing in the first direction X to fit the flower basket body 3.

[0054] Optionally, the two support members 102 can be configured as rectangular blocks, and the support members 102 can extend along the second direction Y. Thus, the two support members 102 can be respectively provided corresponding to the top plate 30 and the bottom plate 31 of the flower basket body 3 to support the flower basket body 3.

[0055] Please see Figure 2 Optionally, the supporting part 1021 can be a groove provided on the support member 102, so that it can not only support the flower basket body 3, but also provide a positioning reference for the connection with the top plate 30 and bottom plate 31 of the flower basket body 3. For example, the supporting part 1021 can be a long groove extending along the second direction Y, that is, the supporting part 1021 can be a rectangular groove, so that it can be adapted to the top plate 30 and bottom plate 31 of the flower basket body 3, so that when the flower basket body 3 is connected to the support member 102, the top plate 30 and bottom plate 31 can be respectively locked in the corresponding groove, preventing the top plate 30 and bottom plate 31 of the flower basket body 3 from shifting during the drying process.

[0056] It is understood that the second direction Y may exemplarily be along the width direction of the substrate 101.

[0057] Optionally, the support member 102 can be fixed to the substrate 101 by fasteners, such as screws or bolts. Of course, the support member 102 can also be fixed to the substrate 101 by, for example, adhesive. The specific method can be set according to the actual situation, and this embodiment does not make a specific limitation.

[0058] In other examples, the base 10 may not include the support member 102. That is, the base 10 may include the base plate 101, and two strip grooves on the base plate 101 are used to connect with the top plate 30 and the bottom plate 31 of the flower basket body 3, respectively. This also achieves the same support for the flower basket body 3.

[0059] In some embodiments, the material of the flow guide 11 can be, for example, PVDF (polyvinylidene fluoride) and PFA (perfluoroalkoxy resin). PVDF offers high cost-effectiveness and is suitable for solar cell production, while PFA is more suitable for high-precision processes in semiconductor manufacturing. The surface of the flow guide 11 can be waterproofed to facilitate the flow of liquid from the flow guide 11 to the base 10.

[0060] Optionally, the guide member 11 can be configured as a rod-shaped structure, that is, the guide member 11 can extend along the first direction X, so that the extension direction of the guide member 11 is consistent with the extension direction of the bottom rod 32 of the basket, so that the guide member 11 can contact the bottom rod 32 of the basket to a greater extent.

[0061] Of course, as another example, the guide 11 can also be a plurality of segments, which can be spaced apart along the first direction X.

[0062] In some embodiments, multiple guide elements 11 are provided, and these multiple guide elements 11 are spaced apart along the second direction Y. Providing multiple guide elements 11 ensures that the number of guide elements 11 is comparable to the number of basket bottom rods 32, avoiding the problem of reduced overall drying efficiency of the basket body 3 due to liquid accumulation in individual basket bottom rods 32 that lack guide elements 11. Furthermore, by providing multiple guide elements 11, even if one or more guide elements 11 malfunction during production, the others can still be used normally. Guide elements 11 in different positions can be replaced to achieve redundancy, thereby improving the overall reliability of the guide device 1. In this example, the number of guide elements 11 is not limited.

[0063] Please see Figure 3 and Figure 4 , Figure 3 This is a front view of the flow guiding device 1 disclosed in the embodiments of this application. Figure 4 for Figure 3A cross-sectional view of AA. In some embodiments, the flow guide 11 can be configured such that the thickness of the second end 112 near the bottom rod 32 is less than that of the first end 111 near the base 10. That is, in the thickness direction of the substrate 101, the flow guide 11 has a structure with one end larger than the other. Specifically, the end of the flow guide 11 that connects to the substrate 101 has a larger thickness, which increases the connection area between the flow guide 11 and the substrate 101, making it less likely for the flow guide 11 to detach from the substrate 101. The end of the flow guide 11 that connects to the bottom rod 32 has a smaller thickness, i.e., the end of the flow guide 11 that connects to the bottom rod 32 is formed into a pointed tip. The thickness difference on both sides can effectively guide the direction of liquid flow and reduce the resistance formed during the flow guidance process. By optimizing the shape and thickness variation of the flow guide 11, the fluid flow is more stable, avoiding the decrease in flow guidance efficiency caused by energy loss due to changes in fluid velocity or direction.

[0064] Optionally, a flow guide sloping surface 113 can be provided at the second end 112 of the flow guide 11, close to the bottom rod 32. The flow guide sloping surface 113 allows the thickness of the second end 112 to be less than the thickness of the first end 111. This not only provides a flow direction for the liquid below the bottom rod 32, but also increases the liquid flow velocity due to the sloping surface, thereby minimizing liquid accumulation on the flow surface due to resistance and improving flow guiding efficiency. Of course, it is understood that in other embodiments, a flow guide arc surface can also be provided to make the thickness of the second end 112 less than the thickness of the first end 111.

[0065] Optionally, the flow guide 11 may be provided with two flow guide slopes 113 at the position where it contacts the bottom rod 32. The two flow guide slopes 113 make the second end 112 of the flow guide 11 form a pointed tip, thereby providing more flow direction and flow space for the liquid accumulated below the bottom rod 32. At the same time, because the surface of the flow guide slope 113 is smooth, it can minimize the slowdown of the liquid flow rate due to resistance, thereby improving the flow guide efficiency.

[0066] Optionally, the vertical cross-section of the guide member 11 can be set to a shape such as a triangle or rhombus that can guide the liquid. Both the triangle and the rhombus have two guiding slopes 113, and the contact surface with the bottom rod of the basket is only a straight line, which can prevent the liquid from accumulating under the bottom rod of the basket 32 ​​and improve the drying efficiency of the basket body 3.

[0067] In some embodiments, the guide 11 can be mounted on the base 10 by fasteners 21, which can ensure the stability of the guide 11 during the production process, improve the stability of contact with the bottom rod 32 of the basket, and ensure that the guide 11 can guide the liquid away from the bottom rod 32 of the basket.

[0068] In other embodiments, the flow guide 11 can also be movably mounted on the base 10. For example, the flow guide 11 can be movably mounted on the substrate 101 of the base 10 via components such as adjusting bolts, adjusting screws, or set screws 20, thereby allowing the flow guide 11 to move in the third direction Z (i.e., the thickness direction of the substrate). In this way, the flow guide device 1 can be adapted to different specifications of flower basket bodies 3 by adjusting the position of the flow guide 11 in the third direction Z, thereby reducing the production cost of the flow guide device 1, saving time for changing flower baskets, and thus improving production efficiency.

[0069] In some embodiments, the flow guide 11 can also be manufactured using a process that integrally forms it with the base 10. Since the flow guide 11 and the base 10 are an integral structure, the structural strength and stability of the flow guide device 1 can be improved, as well as the accuracy and reliability of the flow guide device 1, avoiding problems such as structural instability caused by assembly errors resulting from manual adjustment of the fixing parts.

[0070] The following explanation will take the example of the guide component being movably mounted on the base via the set screw 20.

[0071] Please see Figure 5 and Figure 6 , Figure 5 This is a bottom view of the flow guiding device 1 disclosed in the embodiments of this application. Figure 6 yes Figure 5 The image shows a cross-sectional view of BB. In some embodiments, a through mounting hole 1012 is provided on the substrate, and the flow guiding device 1 further includes an adjusting member 2. The adjusting member 2 passes through the mounting hole 1012 along the third direction Z, and the adjusting member 2 is connected to the flow guiding member 11. The adjusting member 2 is used to adjust the position of the flow guiding member 11 relative to the base 10 in the third direction Z.

[0072] Please see Figure 7 , Figure 7 yes Figure 6 A partial enlarged view of point C in the figure. Optionally, the adjusting member 2 includes a set screw 20 and a fastener 21. The substrate 101 may be provided with a plurality of mounting holes 1012, some of which can be used for the set screw 20 to pass through, and other of which can be used for the fastener 21 to pass through.

[0073] Specifically, the flow guide 11 can be provided with through holes, and one end of each of the multiple set screws 20 of the adjusting member 2 can be respectively inserted into the corresponding mounting holes 1012. The other end of the set screw 20 can abut against the flow guide 11. Then, by fastening the fastener 21 through another mounting hole 1012 and through hole, the flow guide 11 is installed on the substrate 101. At this time, the position of the flow guide 11 is determined.

[0074] When it is necessary to adjust the position of the flow guide 11 relative to the substrate 101, the fastener 21 can be loosened first, then the height of the other end of the set screw 20 protruding from the mounting hole 1012 can be adjusted so that the flow guide 11 abuts against the set screw 20, and finally the fastener 21 can be tightened again.

[0075] It is understood that the fasteners 21 mentioned above may include, but are not limited to, fasteners such as screws and bolts.

[0076] It is understandable that, as another embodiment, the height adjustment of the guide member 11 can be achieved by setting a spring between the guide member 11 and the base 10. By setting a spring between the guide member 11 and the base 10, with both ends of the spring fixed to the guide member 11 and the base 10 respectively, the guide member 11 is pressed tightly against the bottom rod 32 of the basket under the interaction of the downward gravity of the basket body 3 and the upward elastic force of the spring, thus bringing the guide member 11 into contact with the bottom rod 32 of the basket.

[0077] Of course, as another example, the height adjustment of the guide 11 can also be achieved by setting an electric push rod between the guide 11 and the base 10. By setting an electric push rod between the guide 11 and the base 10, with both ends of multiple electric push rods fixed to the guide 11 and the base 10 respectively, and the electric push rods being raised and lowered by a switch, the movement of the electric push rods can be adjusted to adjust the position between the guide 11 and the base 10 according to the required height.

[0078] Please see Figure 8 , Figure 8 This is a schematic diagram of the structure of the substrate with a flow guide 11 and a water passage hole 1011 disclosed in the embodiments of this application. In some embodiments, the base 10 is provided with a water passage hole 1011. Specifically, the water passage hole 1011 is provided on the substrate, adjacent to the flow guide 11. The water passage hole 1011 can effectively prevent the liquid guided by the flow guide 11 from accumulating on the surface of the substrate 101, avoiding the situation where excessive liquid accumulation on the base 10 causes the liquid to overflow the basket bottom rod 32 and contaminate it. In addition, the water passage hole 1011 serves as an auxiliary channel, further dispersing the flow pressure, thereby improving the flow efficiency.

[0079] Optionally, the water passage 1011 can be a round hole, a near-round hole, or a polygonal hole, etc., and this embodiment does not specifically limit it.

[0080] Optionally, the water passage 1011 can be positioned adjacent to the flow guide 11 along the second direction Y. Positioning the water passage 1011 adjacent to the flow guide 11 facilitates faster drainage of the liquid guided by the flow guide 11 from above the base 10 to below the base 10, preventing excess liquid from accumulating above the base 10 and ensuring the flow guiding efficiency of the flow guiding device 1.

[0081] Optionally, the water passage 1011 can be an elongated hole, for example, the water passage 1011 extends along the first direction X. Of course, the extension length of the water passage 1011 can be the same as the extension length of the flow guide 11, or the extension length of the water passage 1011 can be greater than the extension length of the flow guide 11, so that the liquid guided by the flow guide 11 can flow out directly through the water passage 1011, avoiding the accumulation of liquid on the substrate 101.

[0082] Optionally, the number of water passage holes 1011 can be set according to the number of flow guides 11. That is, each flow guide 11 has a water passage hole 1011 on one side, so that the liquid flowing out from the corresponding flow guide 11 can flow out through the corresponding water passage hole 1011, which further helps to improve the liquid flow efficiency.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
