Carrying boat, carrying assembly and support rack

Abstract

The application relates to a bearing boat, a bearing assembly and a support rack. The bearing boat comprises a boat body and a support rack. The boat body has a bearing space and comprises at least two boat tooth rods. All the boat tooth rods are arranged on two sides of the bearing space in a first direction respectively, and each has a first support tooth. The support rack is connected with the boat body and is located on one side of the bearing space in a second direction, and has a second support tooth. The tooth gap of the first support tooth towards the bearing space and the tooth gap of the second support tooth towards the bearing space jointly form a bearing position for bearing a battery piece. When the battery piece is borne, the bearing boat can support the battery piece on two opposite sides through the first support tooth of the boat tooth rod, and can also support the battery piece on a third side through the second support tooth of the support rack. In this way, the bearing boat can form more uniform support on the battery piece to resist the influence of gravity and stress caused by the battery film layer structure, and reduce the warping or deformation of the battery piece.

Description

Technical Field

[0001] This application relates to the field of solar cell manufacturing technology, and in particular to a support boat, a support component, and a support rack. Background Technology

[0002] In the high-temperature coating, diffusion, and oxidation processes of solar cell production, quartz boats are used to support silicon wafers. They ensure the silicon wafers maintain a stable position under high-temperature conditions, preventing collisions and damage, while also ensuring uniform exposure of the wafers to the process gases, guaranteeing process consistency and repeatability.

However, thinner wafers may be more susceptible to external factors such as temperature changes and mechanical stress during the solar cell manufacturing process. Under high-temperature environments, thinner silicon wafers may be more prone to warping or deformation. Utility Model Content

Detailed Implementation

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0034] Furthermore, where the term "and / or" appears, it merely describes the relationship between related objects and indicates that three relationships can exist. For example, A and / or B can represent the relationship between A and B: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates an "or" relationship between the related objects before and after it. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature specified with "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, four, five, etc., unless otherwise explicitly specified.

[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0038] In addition to the background art described, the quartz boats in the related art are two serrated quartz boats on each side, with support points only on both sides of the solar cell. With larger and thinner solar cells, when placed horizontally, the cells are more prone to warping or deformation due to gravity and stress from the film structure. During processes such as pair-by-patch coating or diffusion of the solar cells, the warping or deformation of the two-patch bonding creates larger gaps, allowing specialty gases to more easily penetrate the bonded side of the cells instead of forming the required film on the exposed surface. This results in a more uneven coating on the solar cell surface, and the bonding surface is more prone to large-area wrap-around coating and diffusion.

[0039] For the above issues, please refer to Figure 1 An embodiment of this application provides a support boat 100, including a boat body 10 and a support rack 30. The boat body 10 has a support space 11 and includes at least two boat racks 131. All boat racks 131 are respectively disposed in the support space 11 in a first direction (e.g., Figure 1 The support rack 30 is located on both sides of the X-direction (as shown), and each has a first support tooth arranged along its own longitudinal direction. The support rack 30 is connected to the boat body 10 and is located in the bearing space 11 in the second direction (as shown). Figure 1 It is located on one side in the Y direction (as shown), and has a second support tooth arranged along its own longitudinal direction. The first direction intersects the second direction.

[0040] The tooth gap of the first support tooth facing the bearing space 11 and the tooth gap of the second support tooth facing the bearing space 11 together form a bearing position, which is used to support the battery cell.

[0041] Specifically, the hull 10 may be made of quartz. All the boat teeth 131 form two sets of tooth groups 13, and each set of tooth groups 13 includes at least one boat tooth 131. The two sets of tooth groups 13 are located on both sides of the bearing space 11 in the first direction.

[0042] Understandably, under normal operating conditions of the support boat 100, both the first and second directions can be perpendicular to the direction of gravity, and the first direction can be perpendicular to the second direction. Each first support tooth on the boat tooth rod 131 includes several tooth portions, and all the tooth portions of the first support tooth are evenly distributed along the longitudinal direction of the boat tooth rod 131. The second support tooth on the support rack 30 also includes several tooth portions, and the second support teeth are evenly distributed along the longitudinal direction of the support rack 30. A tooth gap is formed between the tooth portions of adjacent first support teeth, and a tooth gap is formed between the tooth portions of adjacent second support teeth.

[0043] When using the carrier boat 100, the battery cell can be placed in the carrier space 11, and its edge can be inserted into the tooth gap of the first support tooth and the tooth gap of the second support tooth, and is supported by the tooth portion of the first support tooth and the tooth portion of the second support tooth.

[0044] The aforementioned support boat 100, when supporting solar cells, can support the solar cells on both sides via the first support teeth of the boat toothed rod 131, and also on a third side via the second support teeth of the support rack 30. In this way, the support boat 100 can provide more uniform support to the solar cells, resisting the effects of gravity and stress caused by the solar cell film structure, and reducing warping or deformation of the solar cells. When the solar cells are larger and thinner and are bonded in pairs, the uniform support of the support boat 100 can increase the adhesion between the solar cells, thereby reducing the occurrence of wrap-around plating and wrap-around expansion, and improving the uniformity of the solar cell film.

[0045] Specifically, each set of racks 13 includes at least one boat rack 131, the boat rack 131 being in a third direction (e.g., Figure 1 The length in the Z direction (as shown) is the same as the length of the support rack 30 in the third direction.

[0046] The first, second, and third directions are configured to intersect each other in pairs. Under normal operating conditions of the support boat 100, the third direction is the direction of gravity. The longitudinal direction of the boat toothed rod 131 and the longitudinal direction of the support rack 30 are both the third direction.

[0047] The hull 10 also includes two end plates 15, which are respectively located at the two ends of the two sets of toothed rods 13 in the third direction.

[0048] Thus, the rack assembly 13 and the supporting rack 30 can both be installed between the two end plates 15. The end plates 15 provide support for the installation of the rack assembly 13 and the supporting rack 30, and together with the rack assembly 13, they define and form the load-bearing space 11.

[0049] In some embodiments, at least one set of toothed rods 13 includes at least two boat toothed rods 131.

[0050] Understandably, if the rack assembly 13 includes at least two boat racks 131, then all of its boat racks 131 are arranged sequentially along the second direction.

[0051] Each set of toothed rods 13 includes the same number of spur teeth 131, and each set of toothed rods 13 includes two, three, or four spur teeth 131, etc.; or, each set of toothed rods 13 includes different numbers of spur teeth 131, where one set of toothed rods 13 includes one, two, three, or four spur teeth 131, and another set of toothed rods 13 includes one, two, three, or four spur teeth 131, etc., without specific limitations here.

[0052] Thus, the rack assembly 13 includes at least two boat racks 131, which can improve the uniformity of the support of the battery cells on one side of the support boat 100.

[0053] In some embodiments, the pitch of the first support tooth is the same as the pitch of the second support tooth.

[0054] Understandably, the pitch of the first support tooth is the sum of its backlash and tooth thickness, which is also the dimension of the set of teeth and backlash on the first support tooth in the third direction. Similarly, the pitch of the second support tooth is the sum of its backlash and tooth thickness, which is also the dimension of the set of teeth and backlash on the second support tooth in the third direction.

[0055] Each tooth gap of the first support tooth on the swivel gear 131 corresponds one-to-one with each tooth gap of the second support tooth on the support rack 30. In the third direction, the tooth gaps of the first and second support teeth at the same height together form a bearing position.

[0056] The pitch of the first support tooth and the pitch of the second support tooth can be, but are not limited to, 2mm, 2.1mm, 2.18mm, 2.28mm, 2.38mm, 2.5mm or 2.6mm, etc.

[0057] In this way, the first support tooth and the second support tooth can better match each other, providing more uniform support for the battery cell.

[0058] In other embodiments, the tooth pitch of the first support tooth and the tooth pitch of the second support tooth may also be an integer multiple, for example, the tooth pitch of the first support tooth is twice the tooth pitch of the second support tooth, or the tooth pitch of the second support tooth is twice the tooth pitch of the first support tooth, etc., as long as at least a portion of the tooth clearance of the first support tooth can match at least a portion of the tooth clearance of the second support tooth, that is, at least a portion of the tooth clearance of the first support tooth and at least a portion of the tooth clearance of the second support tooth are at the same height in the third direction.

[0059] In the first embodiment, the support rack 30 is integrally connected to the boat body 10. It can be understood that the support rack 30 can be manufactured together with the boat body 10, and both are made of quartz.

[0060] In this way, a reliable connection can be formed between the support rack 30 and the boat body 10, and the support rack 30 does not need to be manufactured separately.

[0061] Please refer to the following: Figures 2 to 4 In the second embodiment, the supporting rack 30 includes a rack body 31 and a connector 33, and the rack body 31 is connected to the boat body 10 through the connector 33.

[0062] Understandably, the second support tooth is located on the rack body 31. The support rack 30 can be additionally connected to the boat hull 10 via its connector 33, and the connection between the support rack 30 and the boat hull 10 can be a detachable connection.

[0063] Thus, the support rack 30 can be attached to the boat 10 by means of addition to provide support for the battery cells.

[0064] Furthermore, the rack body 31 is connected to the spur gear 131 via the connector 33.

[0065] In this way, the rack body 31 can be connected to the sprocket 131 through the connector 33, so as to better maintain parallelism with the sprocket 131.

[0066] Furthermore, the connector 33 includes a connecting portion 331 and a mounting hook portion 333 connected together. The connecting portion 331 is connected to the rack body 31, and the mounting hook portion 333 is hooked onto the spur gear 131.

[0067] Understandably, the assembly hook 333 fits snugly against the boat tooth rod 131, but does not touch the portion of the first support tooth facing the bearing space 11.

[0068] Thus, the rack body 31 is connected to the connector 33 and is hung on the spur gear 131 by the assembly hook 333, and its assembly method is simple and reliable.

[0069] Furthermore, the support rack 30 includes two connectors 33, and each connector 33 includes two mounting hooks 333. The two connectors 33 are connected to both ends of the rack body 31 through their respective connecting parts 331, and the two mounting hooks 333 of each connector 33 are respectively hooked to the two boat tooth rods 131 located on both sides of the bearing space 11.

[0070] Specifically, the two connectors 33 can be located 1 cm from each end of the rack body 31.

[0071] In this way, the support rack 30 can be connected to the boat tooth rods 131 on both sides at both ends, making the connection more stable.

[0072] Specifically, the coefficient of thermal expansion of the material supporting the rack 30 is 1×10⁻⁶. -6 / ℃-30×10 -6 / ℃. Specifically, the material of the supporting rack 30 can be, but is not limited to, 316 stainless steel, etc.

[0073] Thus, since the support rack 30 can be attached to the hull 10 in an additional manner, it can be more flexible in terms of material selection and is not limited to the material of the hull 10.

[0074] In other embodiments, the various parts supporting the rack 30 may also be made of different materials. For example, the rack body 31 may be made of quartz, and the connector 33 may be made of stainless steel.

[0075] This application also provides a support component, which includes a support frame and at least two of the above-mentioned support boats 100. All the support boats 100 are arranged sequentially on the support frame, and the first direction, the second direction and the gravity direction are configured to intersect each other in pairs.

[0076] Understandably, all the support boats 100 can be arranged sequentially on the support frame in a horizontal direction. Both the first and second directions can be configured horizontally and perpendicular to each other. The support frame is used to support each support boat 100.

[0077] Thus, the solar cells are arranged horizontally in the support space 11, and each support boat 100 can hold multiple solar cells. Multiple support boats 100 can be placed together on the support and sent into the furnace together for processes such as coating and diffusion.

[0078] In some embodiments, the carrier boat 100 further includes a support block 50, which is disposed on the side of the boat tooth rod 131 facing away from the carrier space 11 and is supported by a bracket.

[0079] Thus, when the support boat 100 is installed onto the bracket, it only needs to be placed facing the bracket and the support block 50 supported on the bracket.

[0080] Please see Figure 5 This application also provides a support rack 30 for supporting a boat 100, which includes a boat body 10. The boat body 10 has a support space 11 and includes at least two boat tooth bars 131. All boat tooth bars 131 are respectively disposed on both sides of the support space 11 in a first direction, and each has a first support tooth arranged along its own longitudinal direction.

[0081] The support rack 30 is configured to connect to the hull 10 and is located on one side of the bearing space 11 in the second direction, and has a second support tooth arranged along its own longitudinal direction. The first direction intersects the second direction.

[0082] The tooth gap of the first support tooth facing the bearing space 11 and the tooth gap of the second support tooth facing the bearing space 11 together form a bearing position, which is used to support the battery cell.

[0083] Specifically, the hull 10 may be made of quartz. Each set of toothed rods 13 includes at least one toothed rod 131. In other words, all the toothed rods 131 are respectively located on both sides of the bearing space 11 in the first direction, and each has a first support tooth arranged along its own longitudinal direction.

[0084] Understandably, under normal operating conditions of the support boat 100, both the first and second directions can be perpendicular to the direction of gravity, and the first direction can be perpendicular to the second direction. Each first support tooth on the boat tooth rod 131 includes several tooth portions, and all the tooth portions of the first support tooth are evenly distributed along the longitudinal direction of the boat tooth rod 131. The second support tooth on the support rack 30 also includes several tooth portions, and the second support teeth are evenly distributed along the longitudinal direction of the support rack 30. A tooth gap is formed between the tooth portions of adjacent first support teeth, and a tooth gap is formed between the tooth portions of adjacent second support teeth.

[0085] When using the carrier boat 100, the battery cell can be placed in the carrier space 11, and its edge can be inserted into the tooth gap of the first support tooth and the tooth gap of the second support tooth, and is supported by the tooth portion of the first support tooth and the tooth portion of the second support tooth.

[0086] The aforementioned support rack 30 can be used to modify the carrier boat 100 and attached to it. When the carrier boat 100 carries the solar cells, it can provide additional support for the solar cells carried by the carrier boat 100, so that the solar cells are supported more evenly, resisting the effects of gravity and stress caused by the solar cell film structure, and reducing the warping or deformation of the solar cells. When the solar cells are larger and thinner and are attached in pairs, the additional support provided by the support rack 30 can increase the adhesion between the solar cells, thereby reducing the occurrence of wrap-around plating and wrap-around expansion, and improving the uniformity of the solar cell film.

[0087] In some embodiments, the pitch of the first support tooth is the same as the pitch of the second support tooth.

[0088] Understandably, the pitch of the first support tooth is the sum of its backlash and tooth thickness, which is also the dimension of the set of teeth and backlash on the first support tooth in the third direction. Similarly, the pitch of the second support tooth is the sum of its backlash and tooth thickness, which is also the dimension of the set of teeth and backlash on the second support tooth in the third direction.

[0089] Each tooth gap of the first support tooth on the swivel gear 131 corresponds one-to-one with each tooth gap of the second support tooth on the support rack 30. In the third direction, the tooth gaps of the first and second support teeth at the same height together form a bearing position.

[0090] The pitch of the first support tooth and the pitch of the second support tooth can be, but are not limited to, 2mm, 2.1mm, 2.18mm, 2.28mm, 2.38mm, 2.5mm or 2.6mm, etc.

[0091] In this way, the first support tooth and the second support tooth can better match each other, providing more uniform support for the battery cell.

[0092] In other embodiments, the tooth pitch of the first support tooth and the tooth pitch of the second support tooth may also be an integer multiple, for example, the tooth pitch of the first support tooth is twice the tooth pitch of the second support tooth, or the tooth pitch of the second support tooth is twice the tooth pitch of the first support tooth, etc., as long as at least a portion of the tooth clearance of the first support tooth can match at least a portion of the tooth clearance of the second support tooth, that is, at least a portion of the tooth clearance of the first support tooth and at least a portion of the tooth clearance of the second support tooth are at the same height in the third direction.

[0093] In some embodiments, the support rack 30 includes a rack body 31 and a connector 33, wherein the rack body 31 is connected to the boat hull 10 via the connector 33.

[0094] Understandably, the second support tooth is located on the rack body 31. The support rack 30 can be additionally connected to the hull 10 of the carrier boat 100 via its connector 33, and the connection between the support rack 30 and the hull 10 can be a detachable connection.

[0095] Thus, the support rack 30 can be attached to the hull 10 of the carrier boat 100 by means of addition, to provide additional support for the battery cells.

[0096] In some embodiments, the connector 33 includes a connecting portion 331 and a mounting hook portion 333 connected together. The connecting portion 331 is connected to the rack body 31, and the mounting hook portion 333 is configured to hook onto the spur gear 131.

[0097] Understandably, the assembly hook 333 fits snugly against the original boat tooth 131 of the carrier boat 100, but does not touch the part of the first support tooth facing into the carrier space 11.

[0098] Thus, the rack body 31 is connected to the connector 33 and can be hung on the spur gear 131 by the assembly hook 333, and its assembly method is simple and reliable.

[0099] In some embodiments, the support rack 30 includes two connectors 33, and each connector 33 includes two mounting hooks 333. The two connectors 33 are respectively connected to both ends of the rack body 31 through their respective connecting portions 331, and the two mounting hooks 333 of each connector 33 are configured to hook onto the two boat tooth rods 131 located on both sides of the bearing space 11.

[0100] Specifically, the two connectors 33 can be located 1 cm from each end of the rack body 31.

[0101] In this way, the support rack 30 can be connected to the boat tooth rods 131 on both sides at both ends, making the connection more stable.

[0102] The aforementioned support rack 30 is made of 316 stainless steel or other materials with a low coefficient of thermal expansion (coefficient of expansion is 1×10). -6 / ℃-30×10 -6 Made of a material with a temperature of / ℃, and with the same tooth pitch and length as the boat tooth 131 of the carrier boat 100, and placed in the same direction as the boat tooth 131, a connector 33 is provided at 1cm from the upper and lower ends of the carrier boat 100. The end of the connector 33 is hook-shaped and fits into the original boat tooth 131 of the carrier boat 100, but does not touch the part of the first support tooth facing into the support space. Under the joint support of the original boat tooth 131 of the carrier boat 100 and the support rack 30, the battery cell will not fall due to gravity, thereby reducing the gap after the battery cell is attached and reducing the need for plating and expansion.

[0103] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0104] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
