[0044] The embodiments of this utility model are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0046] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] The following is for reference. Figures 1-3 A silicon ingot cleaning machine 10 according to an embodiment of the present invention is described.

[0048] like Figures 1-3 As shown, the silicon ingot cleaning machine 10 according to an embodiment of the present invention is used to clean silicon ingots 20 and includes: a conveying device 1 and a cleaning mechanism 2.

[0049] like Figures 1-3 As shown, the conveying device 1 is used to transport silicon ingot 20; the cleaning mechanism 2 consists of multiple sets, which are arranged at intervals along the conveying direction of the conveying device 1, and are used to clean different surfaces of the silicon ingot 20.

[0050] It is understandable that by setting up multiple cleaning mechanisms 2 along the route of conveying silicon ingot 20 through the conveying device 1, different surfaces of silicon ingot 20 are cleaned respectively, thereby realizing the automated cleaning of silicon ingot 20, avoiding manual cleaning of silicon ingot 20, improving cleaning efficiency, reducing harm to personnel, and all different surfaces of silicon ingot 20 are cleaned, thereby improving the cleaning effect.

[0051] For example, in this utility model, the cleaning mechanism 2 has 6 groups, but this utility model is not limited to this. The cleaning mechanism 2 can also have more groups, such as 7 groups, 8 groups, 9 groups or 10 groups, etc.

[0052] According to the embodiment of the present invention, the silicon ingot cleaning machine 10 conveys the silicon ingot 20 through the conveying device 1. Multiple sets of cleaning mechanisms 2 are arranged at intervals along the conveying direction of the conveying device 1 to clean different surfaces of the silicon ingot 20, thereby realizing automated cleaning of the silicon ingot 20, avoiding manual cleaning of the silicon ingot 20, improving cleaning efficiency, reducing harm to personnel, and cleaning different surfaces of the silicon ingot 20, thereby improving the cleaning effect.

[0053] In some embodiments of this utility model, such as Figures 1-3 As shown, there are at least three sets of cleaning mechanisms 2, each used to clean the three pairs of opposing surfaces of the silicon ingot 20. It is understandable that if only one set of cleaning mechanisms 2 is used to clean the three pairs of opposing surfaces of the silicon ingot 20 simultaneously, the silicon ingot 20 would need to be paused before being flipped, thus affecting the transmission efficiency and consequently the overall cleaning efficiency of the cleaning line.

[0054] In this invention, at least three sets of cleaning mechanisms 2 are used to clean the three pairs of opposing surfaces of the silicon ingot 20, thereby eliminating the need for the silicon ingot 20 to stop and flip, improving the transmission efficiency and the overall cleaning efficiency of the cleaning line.

[0055] In some embodiments of this utility model, such as Figures 1-3 As shown, each cleaning unit 2 includes two cleaning units 2, which are used to clean the two opposite surfaces of the silicon ingot 20 respectively. Therefore, the two opposite surfaces of the silicon ingot 20 can be cleaned simultaneously, thereby further improving the cleaning efficiency.

[0056] In some embodiments of this utility model, such as Figures 1-3 As shown, the conveying device 1 includes a first conveying device 11 and a second conveying device 12. The first conveying device 11 is located upstream of the second conveying device 12 along the conveying direction, and the extending directions of the first conveying device 11 and the second conveying device 12 are perpendicular.

[0057] It is understandable that, as the conveying direction changes, the silicon ingot 20 can be reversed between the first conveying device 11 and the second conveying device 12, which facilitates the cleaning of different surfaces of the silicon ingot 20. At the same time, since the reversal of the silicon ingot 20 is not achieved by flipping the silicon ingot 20, the silicon ingot 20 does not need to be stopped, which improves the conveying efficiency and the cleaning efficiency of the entire cleaning line.

[0058] In some embodiments of this utility model, such as Figures 1-3 As shown, the multiple cleaning mechanisms 2 include a first cleaning mechanism 2, and the two cleaning mechanisms 2 of the first cleaning mechanism 2 are first cleaning mechanisms 21. The two first cleaning mechanisms 21 are located on both sides of the width direction of the first conveying device 11, and are used to clean the two opposite surfaces of the silicon ingot 20 along the width direction of the first conveying device 11.

[0059] It is understandable that the two first cleaning mechanisms 21 are located on both sides of the width direction of the first conveying device 11, thereby avoiding the two first cleaning mechanisms 21 from blocking the advancement of the silicon ingot 20. The two first cleaning mechanisms 21 clean the two opposing surfaces of the silicon ingot 20 along the width direction of the first conveying device 11, thereby improving the cleaning efficiency and cleaning effect of the silicon ingot 20.

[0060] Furthermore, the first set of cleaning mechanisms 2 consists of multiple units spaced apart along the conveying direction, for example, in... Figure 2 In the example shown, there are two first cleaning mechanisms 2, but the present invention is not limited to this. There can be more than one first cleaning mechanism 2, such as three, four, five or six.

[0061] In some embodiments of this utility model, such as Figure 2 As shown, the first cleaning mechanism 21 includes a first cleaning component 211, which is disc-shaped and rotatable. The axis of the first cleaning component 211 and the axis of rotation both extend along the width direction of the first conveying device 11. Bristles are provided on the side of the two first cleaning components 211 facing each other.

[0062] It is understandable that the large surface area of ​​the disc-shaped first cleaning element 211 facilitates complete contact with the two opposing surfaces of the silicon ingot 20 along the width direction of the first conveying device 11, thereby improving the cleaning efficiency and effect of the silicon ingot 20. The bristles not only increase the friction between the first cleaning element 211 and the silicon ingot 20, but also adsorb impurities on the two opposing surfaces of the silicon ingot 20 along the width direction of the first conveying device 11, thereby further improving the cleaning efficiency and effect of the silicon ingot 20.

[0063] In some embodiments of this utility model, such as Figure 2 As shown, the first cleaning mechanism 21 further includes: a first driving member 212, which is connected to the first cleaning member 211 and is used to drive the first cleaning member 211 to rotate; wherein, the first driving member 212 can be a motor, and the output shaft of the motor is connected to the first cleaning member 211, thereby driving the first cleaning member 211 to rotate and realize the cleaning of the silicon ingot 20 by the first cleaning member 211.

[0064] In some embodiments of this utility model, such as Figure 2 As shown, the first cleaning mechanism 21 further includes a second driving member, which is connected to the first cleaning member 211 and is used to drive the first cleaning member 211 to move along the width direction of the first conveying device 11.

[0065] It is understood that the second driving component can be a cylinder. Each of the two first cleaning components 211 that are opposite each other along the width direction of the first conveying device 11 is connected to a second driving component. When the silicon ingot 20 is conveyed between the two first cleaning components 211, the two second driving components drive the two first cleaning components 211 to move toward each other, thereby squeezing the silicon ingot 20 and increasing the friction between the first cleaning component 211 and the silicon ingot 20, thereby further improving the cleaning efficiency and cleaning effect of the silicon ingot 20.

[0066] When the silicon ingot 20 leaves the space between the two first cleaning elements 211, the two second driving elements drive the two first cleaning elements 211 to move away from each other, thereby facilitating the subsequent cleaning of the silicon ingot 20.

[0067] In some embodiments of this utility model, such as Figure 2 As shown, the rotation axis of the first cleaning component 211 is parallel to and spaced apart from the axis. It can be understood that, in order to avoid poor cleaning effect at the center of the first cleaning component 211, the rotation axis of the first cleaning component 211 is parallel to and spaced apart from the axis, thereby causing the first cleaning component 211 to rotate eccentrically, thus improving the cleaning effect at the center of the first cleaning component 211.

[0068] In some embodiments of this utility model, such as Figure 3As shown, the multiple cleaning mechanisms 2 include a second cleaning mechanism 2, and the two cleaning mechanisms 2 in the second group are second cleaning mechanisms 22. The two second cleaning mechanisms 22 are located on opposite sides of the width direction of the second conveying device 12, and are used to clean the two opposite surfaces of the silicon ingot 20 along the width direction of the second conveying device 12.

[0069] It is understood that the two second cleaning mechanisms 22 are located on both sides of the width direction of the second conveying device 12, thereby avoiding the two second cleaning mechanisms 22 from blocking the advancement of the silicon ingot 20. The two second cleaning mechanisms 22 clean the two opposing surfaces of the silicon ingot 20 along the width direction of the second conveying device 12, thereby improving the cleaning efficiency and cleaning effect of the silicon ingot 20.

[0070] Furthermore, the second set of cleaning mechanisms 2 consists of multiple units spaced apart along the conveying direction, for example, in... Figure 2 In the example shown, there are two second cleaning mechanisms 2, but the present invention is not limited to this. There can be more than one second cleaning mechanism 2, such as three, four, five or six.

[0071] In some embodiments of this utility model, such as Figure 3 As shown, the second cleaning mechanism 22 includes a second cleaning component 231, which is cylindrical and rotatable. The axis of the second cleaning component 231 and the axis of rotation both extend along the thickness direction of the second conveying device 12. The outer peripheral wall of the second cleaning component 231 has bristles.

[0072] It is understandable that the cylindrical second cleaning element 231 rotates at a high speed, thereby improving the cleaning efficiency and effect on the silicon ingot 20. The bristles not only increase the friction between the second cleaning element 231 and the silicon ingot 20, but also adsorb impurities on the two opposing surfaces of the silicon ingot 20 along the width direction of the second conveying device 12, thereby further improving the cleaning efficiency and effect on the silicon ingot 20.

[0073] In some embodiments of this utility model, such as Figure 3 As shown, the second cleaning mechanism 22 further includes a third driving member, which is connected to the second cleaning member 231 and is used to drive the second cleaning member 231 to rotate. It can be understood that the third driving member can be a motor, and the output shaft of the motor is connected to the second cleaning member 231, thereby realizing the rotation of the second cleaning member 231 and thus cleaning the silicon ingot 20.

[0074] In some embodiments of this utility model, such as Figure 3As shown, the silicon ingot cleaning machine 10 also includes: a support 3 and a reversing mechanism 4. The conveying device 1 and the cleaning mechanism 2 are both mounted on the support 3. The reversing mechanism 4 is mounted on the support 3. At least a portion of the reversing mechanism 4 is movable along the width direction of the first conveying device 11 to push the silicon ingot 20 from the end of the first conveying device 11 to the beginning of the second conveying device 12.

[0075] It is understandable that, since the extension directions of the first conveying device 11 and the second conveying device 12 are perpendicular and the conveying directions of the first conveying device 11 and the second conveying device 12 are different, it is necessary to realize the reversal of the silicon ingot 20 through the reversing mechanism 4. The silicon ingot 20 is pushed from the end of the first conveying device 11 to the beginning of the second conveying device 12 by the reversing mechanism 4. The method is simple and the switching is quick, which improves the transportation efficiency.

[0076] In some embodiments of this utility model, such as Figure 3 As shown, the second conveying device 12 and the reversing mechanism 4 are respectively located on opposite sides of the first conveying device 11 in the width direction. This facilitates the reversing mechanism 4 in conveying the silicon ingot 20 from the end of the first conveying device 11 to the beginning of the second conveying device 12, which is simple, quick, and improves transportation efficiency.

[0077] In some embodiments of this utility model, the reversing mechanism 4 includes: a push rod and a fourth driving member. The push rod is movable along the width direction of the first conveying device 11 and is used to push the silicon ingot 20 from the end of the first conveying device 11 to the beginning of the second conveying device 12. The output shaft of the fourth driving member is connected to the push rod for driving the push rod to move in the width direction of the first conveying device 11.

[0078] Thus, through the above-described arrangement, at least a portion of the reversing mechanism 4 in this utility model is movable along the width direction of the first conveying device 11, for pushing the silicon ingot 20 from the end of the first conveying device 11 to the beginning of the second conveying device 12.

[0079] The fourth driving component can be a motor. The output shaft of the motor and the push rod can be driven by a gear and rack. Thus, by selecting the gear and rack specifications, torque can be increased and speed reduced. On the one hand, it provides sufficient torque to realize the reversal of the silicon ingot 20. On the other hand, it facilitates the smooth transfer of the silicon ingot 20 from the end of the first conveying device 11 to the beginning of the second conveying device 12.

[0080] In some embodiments of this utility model, such as Figure 3As shown, the first conveying device 11 includes: a conveying shaft 113, a conveyor belt 111, and a fixing seat 112. There are two conveying shafts 113, which are respectively located at both ends of the conveying direction of the first conveying device 11. The conveyor belt 111 is sleeved on the two conveying shafts 113. The fixing seat 112 is fixed on the outer peripheral wall of the conveyor belt 111 and is used to fix the silicon ingot 20. There are multiple fixing seats 112 spaced apart along the conveying direction of the conveyor belt 111, which are used to fix multiple silicon ingots 20 respectively.

[0081] It is understandable that the conveyor belt 111 is rotatably mounted on the two conveyor shafts 113 to ensure the smooth operation of the conveyor belt 111, while the fixed seat 112 is fixed on the outer peripheral wall of the conveyor belt 111, so that the silicon ingot 20 can be fixed on the conveyor belt 111 and move forward as the conveyor belt 111 rotates.

[0082] The fixed base 112 is open on both sides along the width of the conveyor belt 111, which facilitates the reversal of the silicon ingot 20 from the first conveyor device 11 to the second conveyor device 12. The two ends of the fixed base 112 along the conveying direction of the conveyor belt 111 are adapted to abut against the silicon ingot 20, thereby preventing the silicon ingot 20 from sliding relative to the conveyor belt 111 along the conveying direction of the conveyor belt 111, thus ensuring the spacing between the silicon ingots 20.

[0083] In some embodiments of this utility model, such as Figure 1 As shown, the second conveying device 12 includes two guide rails 121, which are spaced apart. There are multiple rollers 122 between the two guide rails 121. Each roller 122 is rotatably connected to both guide rails 121 at both ends along the arrangement direction of the two guide rails 121. The axes of the multiple rollers 122 are parallel to each other and extend along the arrangement direction of the two guide rails 121.

[0084] Thus, the silicon ingot 20 is advanced by the synchronous rolling of multiple rollers 122. It should be noted that the multiple rollers 122 can be connected by gears, chains or timing belts to achieve synchronous rotation among them.

[0085] In some embodiments of this utility model, such as Figure 3 As shown, the multiple cleaning mechanisms 2 include a third cleaning mechanism 2, and the two cleaning mechanisms 2 in the third group are third cleaning mechanisms 23. The two cleaning mechanisms 2 are arranged opposite to each other along the thickness direction of the second conveying device 12. The two third cleaning mechanisms 23 are used to clean the two surfaces of the silicon ingot 20 that are opposite to each other along the thickness direction of the second conveying device 12.

[0086] It is understandable that the two third cleaning mechanisms 23 are located on both sides of the width direction of the second conveying device 12, thereby avoiding the two third cleaning mechanisms 23 from blocking the advancement of the silicon ingot 20. The two third cleaning mechanisms 23 clean the two opposing surfaces of the silicon ingot 20 along the thickness direction of the second conveying device 12, thereby improving the cleaning efficiency and cleaning effect of the silicon ingot 20.

[0087] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the third cleaning mechanism 23 includes a third cleaning component 231. In the two third cleaning mechanisms 23 arranged opposite to each other along the thickness direction of the second conveying device 12, the third cleaning component 231 of one third cleaning mechanism 23 is formed as a roller 122, and the third cleaning component 231 of the other third cleaning mechanism 23 is cylindrical. The outer peripheral wall of the third cleaning component 231 has bristles.

[0088] It is understandable that the cylindrical third cleaning component 231 rotates at a high speed, thereby improving the cleaning efficiency and effect on the silicon ingot 20. The bristles not only increase the friction between the third cleaning component 231 and the silicon ingot 20, but also adsorb impurities on the two surfaces of the silicon ingot 20 with opposite thicknesses along the second conveying device 12, thereby further improving the cleaning efficiency and effect on the silicon ingot 20.

[0089] Meanwhile, since the third cleaning component 231 of one of the third cleaning mechanisms 23 is formed as a roller 122, the roller 122 can be used as both a tool for conveying silicon ingot 20 and a tool for cleaning silicon ingot 20, thus making the roller 122 a dual-purpose device, thereby simplifying the structure and saving costs.

[0090] In some embodiments of this utility model, such as Figure 1 As shown, the silicon ingot cleaning machine 10 also includes a pure water spraying device 5, which is located downstream of the cleaning mechanism 2 along the conveying direction of the silicon ingot 20, and is used to spray clean water onto the silicon ingot 20 located on the conveying device 1. Thus, after the cleaning mechanism 2 has finished cleaning, the pure water spraying device 5 sprays clean water onto the silicon ingot 20, which plays a further cleaning role and improves the cleaning effect.

[0091] Furthermore, multiple pure water spraying devices 5 are installed along the conveying direction of the silicon ingot 20, thereby further improving the cleaning effect. For example, in Figure 1 In the example shown, there are two pure water spraying devices 5, but the present invention is not limited to this. There can be more pure water spraying devices 5, such as 3, 4, 5 or 6, etc.

[0092] In some embodiments of this utility model, such as Figure 1As shown, the silicon ingot cleaning machine 10 also includes a drying device 6, which is located downstream of the pure water spraying device 5 along the conveying direction of the silicon ingot 20, and is used to dry the surface of the silicon ingot 20. Therefore, after cleaning, the silicon ingot 20 can be dried, avoiding impact on subsequent production. It also reduces the need for manual drying of the silicon ingot 20, further saving labor and improving efficiency.

[0093] In some embodiments of this invention, the drying device 6 is an air knife.
