Description

Technical Field

[0001] This disclosure relates to the fields of semiconductor and photovoltaic technology, and in particular to a support paddle. Background Technology

[0002] With the development of semiconductor and photovoltaic technologies, solar cells are widely used in various fields. The manufacturing process of solar cells requires the use of process furnaces to perform various processes on silicon wafers, such as diffusion and coating processes. Taking the diffusion furnace used in the diffusion process as an example, the diffusion furnace is used to dope elements such as phosphorus and boron into silicon wafers, giving them different electrical properties. In the diffusion furnace, the carrier holding the silicon wafer is supported by a support paddle. The support paddle sags significantly due to its own weight, affecting the flow of gas within the furnace and thus the process effect. Utility Model Content

[0007] In some embodiments, the blade has a through-hole area in the vertical direction, the through-hole area extends along the first direction, and the width of the through-hole area increases in the second direction as the distance to the handle increases. The first direction, the second direction and the vertical direction are perpendicular to each other. The supporting blade also includes: a first reinforcing rib assembly connected to the blade, the first reinforcing rib assembly is disposed in the through-hole area, and the first reinforcing rib assembly surrounds the through-hole area to form multiple sets of through-hole patterns.

[0008] In some embodiments, each set of hollowed-out patterns has multiple hollowed-out holes. The first reinforcing rib assembly includes: a central reinforcing rib extending along a first direction, with blades connected to both ends of the central reinforcing rib in the first direction, the central reinforcing rib dividing the hollowed-out area into a first region and a second region arranged along a second direction; multiple connected or disconnected first side reinforcing ribs arranged along the first direction in the first region, the first side reinforcing ribs connecting the central reinforcing rib and the blades; and multiple connected or disconnected second side reinforcing ribs arranged along the first direction in the second region, the second side reinforcing ribs connecting the central reinforcing rib and the blades. The first side reinforcing ribs and the second side reinforcing ribs correspond one-to-one in the second direction. The central reinforcing rib, the first side reinforcing rib, and the second side reinforcing rib enclose the hollowed-out area to form multiple hollowed-out holes of multiple sets of hollowed-out patterns.

[0009] In some embodiments, along the first direction, as the distance from the first side reinforcing rib to the propeller handle increases, the height of the first side reinforcing rib in the vertical direction decreases, and / or, along the first direction, as the distance from the first side reinforcing rib to the propeller handle increases, the thickness of the first side reinforcing rib decreases; and / or, along the first direction, as the distance from the second side reinforcing rib to the propeller handle increases, the height of the second side reinforcing rib in the vertical direction decreases; and / or, along the first direction, as the distance from the second side reinforcing rib to the propeller handle increases, the thickness of the second side reinforcing rib decreases; and / or, the cross-sections of the plurality of first side reinforcing ribs, the plurality of second side reinforcing ribs, and the intermediate reinforcing rib in the hollowed-out area form one of a plurality of star-shaped structures or a plurality of cross-shaped structures arranged along the first direction; and / or, the cross-section of the hollowed-out hole includes one of a circle, a square, or a triangle.

[0010] In some embodiments, the blade has a bearing surface on one side in the vertical direction, the bearing surface is configured as a support carrier, the bearing surface has a recess, and a hollow pattern is arranged on the bottom wall of the recess.

[0016] This disclosure provides a support paddle that features multiple perforated patterns extending along a first direction on its blades. The cross-sectional area of ​​at least a portion of the perforated patterns increases with the distance from the perforated patterns to the paddle handle. On one hand, the perforated patterns allow gas to pass through and quickly distribute around the sheet material, thereby improving airflow and thus enhancing the processing effect on the sheet. On the other hand, the perforated patterns help reduce the weight of the support paddle itself. Furthermore, the use of multiple perforated patterns with varying cross-sectional areas maximizes air permeability while avoiding excessive perforation that could reduce the paddle's support strength, thus achieving a balance between high air permeability and high support strength.

[0028] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0029] Figure 1 The diagram shown is a simplified schematic of a process furnace provided in one embodiment of this disclosure. Figure 2 The diagram shown is a schematic diagram of a support paddle provided in an embodiment of this disclosure. Figure 3 The diagram shown is a schematic diagram of a support paddle provided in another embodiment of this disclosure. Figure 4 As shown Figure 3 The image shows a magnified view of part A of the support propeller. Arrow X points to the first direction, arrow Y to the second direction, and arrow Z to the vertical direction. The first direction X, the second direction Y, and the vertical direction Z are all perpendicular to each other, and this will not be emphasized separately thereafter.

[0030] This disclosure provides a support paddle, such as Figures 1 to 4 The support paddle 1 includes a paddle shank 11 and a paddle blade 12. The paddle blade 12 extends along a first direction X and is connected to one side of the paddle shank 11 in the first direction X. The paddle blade 12 is configured to support the carrier 3.

[0031] Optionally, the carrier 3 can be a boat structure, a flower basket, or the like, used to support multiple sheets. The sheets can be semiconductor or photovoltaic materials used to prepare solar cells, and the shapes of the sheets include square, round, etc. Their specific dimensions can be adapted to actual needs and are not specifically limited.

[0032] It is understood that the support paddle 1 is applied to the process furnace 10, which has a furnace cavity 21. The support paddle 1 is used to carry the carrier 3 and send the carrier 3 into or out of the furnace cavity 21. When the support paddle 1 sends the carrier 3 into the furnace cavity 21, the support paddle 1 is used to support the carrier 3 so that the sheet in the carrier 3 remains stable in the furnace cavity 21.

[0033] Optionally, the process furnace 10 can be used for coating processes, diffusion processes, etc., on sheets, and can be adapted to meet actual needs. The process furnace 10 includes a furnace body 2, which has a furnace cavity 21 extending along a first direction X. The process furnace 10 also includes a plurality of air inlet pipes 22 arranged within the furnace cavity 21 along the first direction X (which is also the extension direction of the furnace cavity 21), with the plurality of air inlet pipes 22 spaced apart around the inner sidewall of the furnace cavity 21. When the support paddle 1 supports the carrier 3 within the furnace cavity 21, the air inlet of at least one air inlet pipe 22 is located below the support paddle 1.

[0034] Optionally, the carrier 3 can be placed on a pallet, and the support paddle 1 is used to move or support the pallet, without specific limitation.

[0035] The process furnace 10 has a furnace door. When the furnace door is open, the support paddle 1 carries the carrier 3 from one side of the furnace door into the furnace cavity 21, so that the carrier 3 is located inside the furnace cavity 21. At this time, the blade 12 of the support paddle 1 is located inside the furnace cavity 21 and is used to support the carrier 3. The paddle handle 11 is located near the furnace door and is detachably and fixedly connected to the process furnace 10. One end of the blade 12 near the furnace door is connected to the paddle handle 11, and the other end is not connected or is snapped into the inner wall of the furnace cavity 21, so that the support paddle 1 forms a cantilever support paddle 1 for supporting the carrier 3 inside the furnace cavity 21, which facilitates the processing of the sheet in the carrier 3 and facilitates the removal and placement of the carrier 3 from the furnace cavity 21.

[0036] The blade 12 is provided with multiple sets of hollow patterns 121 arranged along the first direction X. The hollow patterns 121 penetrate the blade 12 in the vertical direction Z. Along the first direction X, as the distance from the hollow pattern 121 to the handle 11 increases, the cross-sectional area of ​​at least some of the hollow patterns 121 increases.

[0037] The support paddle 1 provided in this embodiment features a plurality of perforated patterns 121 extending along a first direction X on the paddle blade 12. The cross-sectional area of ​​at least a portion of the perforated patterns 121 increases as the distance from the perforated patterns 121 to the paddle handle 11 increases. On one hand, the perforated patterns 121 allow gas to pass through and quickly distribute around the sheet, thereby improving airflow and thus enhancing the processing effect on the sheet. On the other hand, the perforated patterns 121 help reduce the weight of the support paddle 1 itself. Furthermore, the multiple perforated patterns 121 with varying cross-sectional areas maximize air permeability while avoiding excessive perforations that could reduce the support strength of the paddle blade 12, thus achieving a balance between high air permeability and high support strength.

[0038] In some alternative embodiments, such as Figure 2 The plurality of hollow patterns 121 include a plurality of first sub-hollow patterns 1211 and a plurality of second sub-hollow patterns 1212. Along the first direction X, the first sub-hollow patterns 1211 and the second sub-hollow patterns 1212 are arranged alternately, and the cross-sectional area of ​​an adjacent first sub-hollow pattern 1211 is larger than the cross-sectional area of ​​a second sub-hollow pattern 1212. Among the plurality of first sub-hollow patterns 1211 arranged along the first direction X, the cross-sectional area of ​​the first sub-hollow pattern 1211 increases as the distance from the first sub-hollow pattern 1211 to the propeller 11 increases, and / or, among the plurality of second sub-hollow patterns 1212 arranged along the first direction X, the cross-sectional area of ​​the second sub-hollow pattern 1212 increases as the distance from the second sub-hollow pattern 1212 to the propeller 11 increases.

[0039] In other alternative embodiments, such as Figure 3 The cross-sectional areas of the multiple hollow patterns 121 can all be set to be different, and along the first direction X, as the distance from the hollow pattern 121 to the propeller 11 increases, the cross-sectional area of ​​the hollow pattern 121 increases.

[0040] It should be emphasized that, in other embodiments, among the multiple sets of hollow patterns 121 arranged on the blade 12, two or more second sub-hollow patterns 1212 may be arranged between two adjacent first sub-hollow patterns 1211, and the cross-sectional areas of the second sub-hollow patterns 1212 between two first sub-hollow patterns 1211 may be equal or unequal. Alternatively, the arrangement of multiple hollow patterns 121 may be based on the above embodiments, such that the cross-sectional area of ​​the hollow pattern 121 farthest from the handle 11 is the smallest among all hollow patterns 121, or the cross-sectional area of ​​the hollow pattern 121 farthest from the handle 11 is smaller than the cross-sectional area of ​​the adjacent previous hollow pattern 121. Specific adjustments can be made according to actual needs and are not specifically limited. In this embodiment, using... Figure 4Taking the example of a scheme in which multiple hollow patterns 121 are configured such that the cross-sectional area of ​​the hollow patterns 121 gradually increases as the distance to the propeller handle 11 increases, the structure of the supporting propeller 1 will be described in detail.

[0041] like Figure 4 The perforated pattern 121 is composed of one or more perforated holes 121a that are spaced apart or connected to each other. In this embodiment of the present disclosure, each perforated pattern 121 is composed of multiple perforated holes 121a, such as... Figure 3 Each dotted frame contains multiple hollow holes 121a of the same or different shapes and sizes. Multiple hollow holes 121a located in the same dotted frame constitute a set of hollow patterns 121. The cross-sectional area of ​​a set of hollow patterns 121 refers to the total cross-section of multiple hollow holes 121a.

[0042] Optionally, the number, size, and specific shape of the perforated holes 121a in the multiple sets of perforated patterns 121 can be the same or different. In this embodiment of the present disclosure, the number and shape of the perforated holes 121a in the multiple sets of perforated patterns 121 are set to be the same, the difference being that the size is different, so that each perforated pattern 121 has a different cross-sectional area.

[0043] Optionally, the shape of the cross-section of the perforated hole 121a may include a circle, a square, a triangle, a polygon, etc., and can be adapted to the actual situation without being specifically limited.

[0044] Figure 5 As shown Figure 3 A magnified view of part B of the support propeller shown. Figure 6 As shown Figure 3 A magnified view of part C of the support propeller shown. Figure 7 The image shown is a top view of a support paddle provided in an embodiment of this disclosure. Figure 8 The image shown is a bottom view of a support paddle provided in an embodiment of this disclosure.

[0045] like Figure 4 and Figure 5 The blade 12 has a through-hole area in the vertical direction Z. The through-hole area extends along the first direction X. As the distance to the handle 11 increases, the width of the through-hole area in the second direction Y increases. The supporting blade 1 also includes a first reinforcing rib assembly 14. The first reinforcing rib assembly 14 is connected to the blade 12 and is disposed in the through-hole area. The first reinforcing rib assembly 14 encloses and forms multiple sets of through-hole patterns 121 in the through-hole area, which is beneficial to increase the strength of the blade 12 itself while maximizing the gas throughput and reducing the sag of the blade 12.

[0046] Specifically, the first reinforcing rib assembly 14 includes a central reinforcing rib 141, a plurality of connected or disconnected first side reinforcing ribs 142, and a plurality of connected or disconnected second side reinforcing ribs 143. The central reinforcing rib 141 extends along a first direction X, and the blades 12 are connected to both ends of the central reinforcing rib 141 in the first direction X. The central reinforcing rib 141 divides the hollow area into a first region and a second region arranged along a second direction Y. The plurality of connected or disconnected first side reinforcing ribs 142 are arranged in the first region along the first direction X, and the first side reinforcing ribs 142 connect the central reinforcing rib 141 and the blades 12. The plurality of connected or disconnected second side reinforcing ribs 143 are arranged in the second region along the first direction X. The second side reinforcing ribs 143 connect the central reinforcing rib 141 and the blades 12. The first side reinforcing ribs 142 and the second side reinforcing ribs 143 correspond one-to-one in the second direction Y. The central reinforcing rib 141, the first side reinforcing ribs 142, and the second side reinforcing ribs 143 enclose a plurality of hollow holes 121a of a plurality of hollow patterns 121 in the hollow area.

[0047] Optionally, in the second direction Y, the cross-section of each corresponding first side reinforcing rib 142 and second side reinforcing rib 143 is a V-shaped structure mirrored relative to the middle reinforcing rib 141, so that the cross-section of the first reinforcing rib assembly 14 in each hollow area is a star-shaped structure, which reduces the weight of the blade 12 while ensuring the support strength of the blade 12 to the carrier 3 and reduces the sag.

[0048] It is understandable that the arrangement of gradually increasing width of the hollow area in the second direction Y as the distance to the propeller 11 increases will result in different V-shaped angles of the corresponding first side reinforcing rib 142 and second side reinforcing rib 143 in different hollow patterns 121. As the distance to the propeller 11 increases, the V-shaped angle decreases and the size of the side reinforcing rib increases so that it can be fixedly connected with the middle reinforcing rib 141 and the propeller blade 12 at different hollow areas.

[0049] Optionally, the intermediate reinforcing rib 141, the first side reinforcing rib 142, and the second side reinforcing rib 143 can be integrally formed to improve the strength of the blade 12 itself.

[0050] Optionally, the first reinforcing rib assembly 14 can be welded to the blade 12 or integrally formed with the blade 12, without specific limitations.

[0051] It should be emphasized that the cross-sectional shape of the set of hollow patterns 121 formed by the first reinforcing rib assembly 14 can be a cross-shaped structure, a grid-shaped structure, etc., and different reinforcing rib layouts can be matched according to different shapes, without specific limitations.

[0052] In some alternative embodiments, along the first direction X, as the distance to the propeller 11 increases, the height of the propeller blade 12 in the vertical direction Z decreases, which helps to reduce the overall weight of the propeller 1.

[0053] Optionally, the propeller 11 has a first height in the first direction X, and the maximum height of the blade 12 in the vertical direction Z is less than the first height, to ensure the reliability of the connection between the propeller 11 and the inner wall of the furnace cavity 21, and to provide higher support for the blade 12.

[0054] Optionally, along the first direction X, as the distance from the first side reinforcing rib 142 to the propeller handle 11 increases, the height of the first side reinforcing rib 142 in the vertical direction Z decreases; along the first direction X, as the distance from the second side reinforcing rib 143 to the propeller handle 11 increases, the height of the second side reinforcing rib 143 in the vertical direction Z decreases; along the first direction X, as the distance from the first side reinforcing rib 142 to the propeller handle 11 increases, the thickness of the first side reinforcing rib 142 decreases; along the first direction X, as the distance from the second side reinforcing rib 143 to the propeller handle 11 increases, the thickness of the second side reinforcing rib 143 decreases. This further reduces the weight of the supporting propeller 1.

[0055] In some alternative embodiments, the blade 12 has a bearing surface 122 on one side in the vertical direction Z. The bearing surface 122 is configured to support the carrier 3. The bearing surface 122 has a recess 15, and a hollow pattern 121 is arranged on the bottom wall of the recess 15. By setting the recess 15, the first reinforcing rib assembly 14 will not be higher than the bearing surface 122 in the vertical direction Z, thereby ensuring the stability of the contact between the bearing surface 122 and the carrier 3.

[0056] like Figure 7 The propeller 11 has a first width L1 in the second direction Y, and the propeller blade 12 has a second width L2 in the second direction Y. The second width L2 is greater than the first width L1, so that the propeller blade 12 can be used to support the carrier 3, and the propeller 11 can be used to fix and connect to the furnace door or furnace cavity 21.

[0057] like Figure 6 The propeller handle 11 has a through hole 111 extending along the first direction X. The propeller 1 also includes a second reinforcing rib assembly 112. The second reinforcing rib assembly 112 is connected to the propeller handle 11. The second reinforcing rib assembly 112 is disposed in the through hole 111 and extends along the first direction X, so as to reduce the weight of the propeller handle 11 while ensuring that the propeller handle 11 has high strength.

[0058] Optionally, the second reinforcing rib assembly 112 includes a plurality of reinforcing ribs extending along the first direction X, and the plurality of reinforcing ribs form a cross-shaped structure or a star-shaped structure in the cross-section of the through hole 111. In other examples, the plurality of reinforcing ribs may also form a multi-mesh structure, a grid-shaped structure, etc. in the cross-section of the through hole 111, without specific limitation.

[0059] like Figure 5 and Figure 8 The supporting paddle 1 also includes a transition section 13 and a third reinforcing rib assembly 132. The transition section 13 connects the paddle handle 11 and the paddle blade 12 at its two ends in the first direction X, respectively. The transition section 13 has an inclined surface 131 on one side in the vertical direction Z and a groove on the other side, with the third reinforcing rib assembly 132 disposed in the groove. The transition section 13 smoothly connects the paddle handle 11 and the paddle blade 12, which are of different sizes, thereby reducing the risk of breakage at the connection point. In addition, the third reinforcing rib assembly 132 provided in the transition section 13 helps to further reduce the weight of the supporting paddle 1 while ensuring the supporting strength.

[0060] It is understood that the third reinforcing rib assembly 132 can be specifically set on the bottom wall of the groove, and the third reinforcing rib assembly 132 can be set as a protruding structure on the bottom wall. The pattern of the protruding structure can be a star shape, a ring, a cross shape, etc., and can be adapted to actual needs without being specifically limited.

[0061] Optionally, the propeller 11, transition section 13 and blade 12 are integrally formed to further improve the strength of the supporting propeller 1.

[0062] Optionally, the support paddle 1 is made of silicon carbide material.

[0063] In the embodiments of this disclosure, unless otherwise specified, the connection can be a detachable connection using bolts and nuts, screws, clips, magnetic attraction, etc. In some connections where there is no particular requirement for a detachable fit, a non-detachable connection can be achieved through welding, bonding, or other methods.
