[0033] Embodiment 1

[0034] See also Figure 1 , is a structural schematic diagram of a flower basket 100 provided in Example 1 of the utility model, the flower basket 100 includes a first end plate 10, a second end plate 11, a plurality of bearing rods 12 and a liquid scraping ring 13, the second end plate 11 and the first end plate 10 are arranged at intervals along the length direction x of the flower basket 100, the two ends of each bearing rod 12 are respectively connected to the first end plate 10 and the second end plate 11, the plurality of bearing rods 12 are provided with a card slot 12a, the card slot 12a is used to install a silicon wafer (not shown), at least part of the bearing rods 12 are movably provided with a liquid scraping ring 13, the liquid scraping ring 13 can be moved relative to the bearing rods 12 to the two ends of the bearing rods 12 to remove liquid on the corresponding bearing rods 12.

[0035] In this embodiment, the first end plate 10 and the second end plate 11 are arranged at intervals along the length direction x of the flower basket 100, and a plurality of bearing rods 12 are arranged between the first end plate 10 and the second end plate 11. The bearing rods 12 are used to set the slots 12a to install the silicon wafers. In this way, the flower basket 100 can perform acid washing, alkali washing or water washing on the silicon wafers in the slow pulling device. At the same time, the scraping ring 13 is moved relative to the bearing rod 12, and the scraping ring 13 can remove the liquid on the bearing rod 12 as much as possible, thereby reducing the temperature required for drying, reducing the drying time, and reducing the energy consumption and cost of drying.

[0036] In some embodiments, such as Figure 1 and Figure 2At least part of the load-bearing rods 12 are provided with slide grooves 12b, each slide groove 12b extends from one end of the load-bearing rod 12 to the other end of the load-bearing rod 12, the scraper ring 13 includes a main body 131 and a connecting portion 132 provided on the main body 131, the connecting portion 132 is slidably connected to the slide groove 12b, and the main body 131 is used to abut against the load-bearing rod 12 when the scraper ring 13 moves along the slide groove 12b to remove the liquid on the corresponding load-bearing rod 12. In this way, the connecting part 132 is slidably connected with the slide groove 12b, so that the scraper ring 13 can slide along the slide groove 12b. Then, after the flower basket 100 is pickled, alkaline washed or water washed on the silicon wafer by the slow pulling equipment, the scraper ring 13 can move from one end of the carrying rod 12 to the other end along the slide groove 12b. During this process, the main body 131 abuts against the carrying rod 12, and the liquid attached to the carrying rod 12 is gathered to one end of the carrying rod 12 under the scraping of the main body 131. The gravity of the gathered liquid is relatively large, which is not enough to attach to the carrying rod 12 by using surface tension. It is separated from the carrying rod 12 under the action of gravity, thereby removing the liquid on the carrying rod 12.

[0037] For example, Figure 3 As shown, there are two slide grooves 12b, which are respectively located on both sides of the bearing rod 12 along the width direction y of the flower basket 100, the main body 131 is constructed in a semi-circular shape, and the main body 131 is located on the side of the bearing rod 12 away from the slot 12a, and there are two connecting parts 132, which are respectively arranged at both ends of the main body 131, and the two connecting parts 132 are respectively slidably connected to the two slide grooves 12b. In this way, on the one hand, the connection reliability between the wiper ring 13 and the bearing rod 12 can be improved by sliding the two connecting parts 132 with the two slide grooves 12b, and the wiper ring 13 slides relatively stably relative to the bearing rod 12. On the other hand, the main body 131 is constructed in a semi-annular shape, and the main body 131 is located on the side of the supporting rod 12 away from the slot 12a. When the scraper ring 13 moves along the slide groove 12b, the main body 131 can just scrape away the liquid attached to the bottom of the supporting rod 12 (i.e., the side away from the slot 12a) due to the action of gravity and surface tension, and can avoid interference with the slot 12a.

[0038] Alternatively, if Figure 4 As shown, the extension direction p of the chute 12b forms an angle α with the length direction x, 0°<α≤15°. In this way, by making the extension direction p of the chute 12b form an angle α with the length direction x, the liquid scraping ring 13, under the action of its own gravity, part of the gravity force is consistent with the extension direction of the chute 12b, and the liquid scraping ring 13 can slide along the chute 12b from the higher end to the lower end of the chute 12b by itself, without the need to set up additional power components to provide power, thus saving energy consumption and simplifying the overall structure of the flower basket 100.

[0039] Furthermore, the angle α between the extension direction of the slide groove 12b and the length direction x may be 2°, 4°, 6°, 8°, 10°, 12°, 14°, 15°, etc., which is not specifically limited in this embodiment.

[0040] For example, Figure 5 and Figure 6 As shown, the flower basket 100 further includes a limiting assembly 14, which is disposed on the bearing rod 12, and is used to be connected to the main body 131 to limit the main body 131 from moving along the slide groove 12b, or to be separated from the main body 131 to release the restriction. In this way, by providing the limiting assembly, it is possible to control whether the scraper ring 13 performs the action of removing liquid. For example, when the flower basket 100 is acid-washing, alkali-washing or water-washing the silicon wafers in the slow pulling equipment, and the flower basket 100 is drying the silicon wafers in the drying equipment, the limiting component 14 can be connected to the main body 131 to limit the movement of the main body 131 along the slide groove 12b, so that the scraper ring 13 is located at one end or other position of the slide groove 12b. Being located at one end is conducive to the scraper ring 13 to remove the liquid. When the flower basket 100 needs to remove the liquid attached to the flower basket 100 before drying the silicon wafers in the drying equipment, the limiting component 14 can be separated from the main body 131 to limit the contact. At this time, the main body 131 can move along the slide groove 12b under the action of gravity to remove the liquid.

[0041] Exemplarily, the limiting assembly 14 includes a fixed portion 141 and a movable portion 142, wherein the fixed portion 141 is disposed on the bearing rod 12, and the movable portion 142 can move relative to the fixed portion 141 to abut against the main portion 131 to limit the movement of the main portion 131 along the slide groove 12b, or can move relative to the fixed portion 141 to separate from the main portion 131 to release the restriction. In this way, when it is necessary to limit the movement of the wiper ring 13 relative to the slide groove 12b, the movable portion 142 can move relative to the fixed portion 141 to abut against the main portion 131. When it is necessary to release the restriction on the sliding of the wiper ring 13 relative to the slide groove 12b, the movable portion 142 can move relative to the fixed portion 141 to separate from the main portion 131.

[0042] Alternatively, if Figure 6 As shown, the bearing rod 12 is provided with a mounting groove 12c, the fixing portion 141 is provided in the mounting groove 12c, and the movable portion 142 can move relative to the fixing portion 141 to protrude out of the mounting groove 12c and abut against the main body 131, or, as shown in FIG. Figure 7As shown, the movable portion 142 can be moved relative to the fixed portion 141 and hidden in the mounting groove 12c and separated from the main body 131. In this way, when it is necessary to restrict the movement of the liquid scraping ring 13 relative to the slide groove 12b, the movable portion 142 can be moved relative to the fixed portion 141 to protrude out of the mounting groove 12c and abut against the main body 131. When it is necessary to release the restriction on the sliding of the liquid scraping ring 13 relative to the slide groove 12b, the movable portion 142 can be moved relative to the fixed portion 141 and hidden, and separated from the main body 131, and the mounting groove 12c can be used to accommodate the fixed portion 141 and the movable portion 142, thereby reducing the overall volume of the flower basket 100.

[0043] For example, see again Figure 1 The plurality of bearing rods 12 are respectively a first side rod 121, a second side rod 122 and a bottom rod 123. The first side rod 121 and the second side rod 122 are arranged at intervals along the width direction y of the flower basket 100. The bottom rod 123 is located below the first side rod 121 and the second side rod 122. The bottom rod 123 is provided with a liquid scraping ring 13. In this way, the first side rod 121 and the second side rod 122 are arranged at intervals along the width direction y of the flower basket 100. The clamping groove 12a of the first side rod 121 and the clamping groove 12a of the second side rod 122 can fix the two sides of the silicon wafer, and the bottom rod 123 located below the first side rod 121 and the second side rod 122 can carry the silicon wafer and fix the bottom side of the silicon wafer by using the clamping groove 12a, thereby improving the reliability of silicon wafer installation. Furthermore, the flower basket 100 performs acid washing, alkali washing or water washing on the silicon wafer in the slow pulling device, and the liquid is mainly concentrated and attached to the bottom rod 123. The scraper ring 13 provided on the bottom rod 123 can remove most of the liquid.

[0044] In some other embodiments, the first side rod 121 and the second side rod 122 may also be provided with a liquid scraping ring 13 .

[0045] Optionally, the number of the first side bar 121, the second side bar 122 and the bottom bar 123 may be one or more, which is not specifically limited in this embodiment. Figure 1 As shown, Figure 1 The number of the first side bars 121 , the second side bars 122 , and the bottom bars 123 shown is two each.

[0046] In some embodiments, the flower basket 100 further includes a driving assembly (not shown), which is used to drive the scraper ring 13 to move relative to the supporting rod 12 to the two ends of the supporting rod 12. In this way, the scraper ring 13 is driven by the driving assembly, and the degree of automation is high, so that liquid can be removed at an appropriate time.

[0047] Exemplarily, the driving assembly includes a motor and a screw mechanism, the motor is disposed on the first end plate 10 or the second end plate 11, the screw mechanism is connected to the motor and the liquid scraping ring 13, and the screw mechanism is used to drive the liquid scraping ring 13 to move relative to the supporting rod 12 to the two ends of the supporting rod 12 under the drive of the motor. In this way, when the flower basket 100 is acid-washed, alkaline-washed or water-washed on the silicon wafer in the slow pulling device, the motor can drive the screw mechanism to move, and the screw mechanism converts the rotational motion output by the motor into linear motion, so that the screw mechanism can drive the liquid scraping ring 13 to move along the slide groove 12b, thereby removing the liquid.

[0048] The utility model provides a flower basket 100 in the first embodiment, wherein a first end plate 10 and a second end plate 11 are arranged at intervals along the length direction x of the flower basket 100, a plurality of bearing rods 12 are arranged between the first end plate 10 and the second end plate 11, and a slot 12a is arranged on the bearing rod 12 to install silicon wafers, so that the flower basket 100 can perform acid washing, alkali washing or water washing on the silicon wafers in a slow pulling device. At the same time, the scraping ring 13 is moved relative to the bearing rod 12, and the scraping ring 13 can remove the liquid on the bearing rod 12 as much as possible, thereby reducing the temperature required for drying, reducing the drying time, and reducing the energy consumption and cost of drying.

[0050] See also Figure 7 , which is a schematic structural diagram of a slow pulling device 200 provided in Example 2 of the utility model. The slow pulling device 200 includes a moving device 20, a slow pulling groove 21 and the flower basket 100 of Example 1. The flower basket 100 is arranged on the moving device 20, and the moving device 20 is used to drive the flower basket 100 to move into or out of the slow pulling groove 21.

[0051] Exemplarily, the moving device 20 is used to drive the flower basket 100 to descend along the first direction q to the inside of the slow-lifting groove 21, or to ascend along the first direction q to the outside of the slow-lifting groove 21, and the angle between the first direction q and the height direction z of the flower basket 100 is β, 0°<β≤15°. In this way, by making the angle between the first direction q and the height direction z of the flower basket 100 β, in the process of ascending the flower basket 100 along the first direction q to the outside of the slow-lifting groove 21, the flower basket 100 is tilted and lifted as a whole, and the liquid scraping ring 13, under the action of its own gravity, has a partial component of gravity that is consistent with the length direction of the bearing rod 12, and the liquid scraping ring 13 can slide along the bearing rod 12 from the higher end to the lower end of the bearing rod by itself, without the need to set up an additional power component to provide power, thus saving energy consumption and simplifying the overall structure of the flower basket 100.

[0052] Moreover, the angle β between the first direction q and the height direction z of the flower basket 100 may be 2°, 4°, 6°, 8°, 10°, 12°, 14°, 15°, etc., which is not specifically limited in this embodiment.
