Abstract
Description
Technical Field
[0001] This application relates to the field of photovoltaic automation equipment, and more specifically, to a boat support. Background Technology
[0002] In the photovoltaic manufacturing industry, CVD (Chemical Vapor Deposition) is commonly used to coat silicon wafers. Currently, some manufacturers use a wafer support with positioning grooves on its upper surface to feed the wafer boat into the CVD furnace. The wafer boat is supported by lugs on both sides of the support in the positioning grooves. However, the positioning grooves reduce the structural strength of the side plates, making them prone to breakage when supporting a large number of wafer boats. Utility Model Content
[0003] To solve the above-mentioned technical problems, this application provides a boat support, which adopts the following technical solution:
[0004] A boat support includes a first side plate and a second side plate, and two end plates. The first side plate and the second side plate both extend along a first horizontal direction. One end plate is fixedly connected to a first end of the first side plate and the second side plate, and the other end plate is fixedly connected to a second end of the first side plate and the second side plate. The boat support also includes at least one set of limiting parts, which includes a first limiting member and a second limiting member. The first limiting member is disposed on the upper inner side of the first side plate, and the second limiting member is disposed on the upper inner side of the second side plate. The positions of the first limiting member and the second limiting member are correspondingly arranged.
[0005] By setting limiting parts on the inner side of the two side plates, the structural strength reduction caused by opening positioning grooves can be avoided, thereby preventing breakage accidents.
[0006] Optionally, the first limiting member includes at least one pair of adjacent first limiting blocks and second limiting blocks, and a limiting gap is formed between the pair of first limiting blocks and second limiting blocks for limiting the lugs on the silicon wafer boat. Both the first limiting blocks and the end of the limiting block near the limiting gap are provided with a chamfer, and the second limiting member has the same structure as the first limiting member.
[0007] By setting two adjacent limiting blocks, the support ears on the same side of the same silicon wafer boat are limited, preventing the silicon wafer boat from sliding along the length of the side plate after it is placed on the boat support; the chamfer is used to provide guidance so that the support ears can smoothly abut against the limiting blocks.
[0008] Optionally, the first limiting member includes a third limiting block, which is used to limit the lugs on a silicon wafer boat, and the second limiting member has the same structure as the first limiting member.
[0009] By setting two third limiting blocks to limit the lugs on both sides of the same silicon wafer boat, it is possible to prevent the silicon wafer boat from sliding along the length of the side plate.
[0010] Optionally, the first limiting member includes at least two strip plates that are spaced apart and extend along the circumferential support direction, and the gap formed between two adjacent strip plates is used to limit the lugs on the silicon wafer boat. The second limiting member has the same structure as the first limiting member.
[0011] Setting at least two strip plates will create a gap, which will limit the movement of the silicon wafer boat and prevent it from sliding.
[0012] Optionally, the first limiting member includes a fourth limiting block, the upper surface of which is provided with at least one limiting groove extending along a second horizontal direction for limiting the lugs on the silicon wafer boat. The second horizontal direction is perpendicular to the first horizontal direction. The second limiting member has the same structure as the first limiting member.
[0013] By setting the first limiting member as a limiting block with a limiting groove, it can cooperate with the lug of the silicon wafer boat to achieve the purpose of limiting.
[0014] Optionally, the distance between the two sidewalls of the limiting groove is set to gradually decrease in the direction toward the bottom of the groove.
[0015] This design provides guidance and restraint for the supports of the silicon wafer boat during the overlapping process.
[0016] Optionally, the boat support also includes a connecting plate, the two ends of which are fixedly connected to the middle of the first side plate and the second side plate, respectively.
[0017] By setting up connecting plates, the overall stability of the boat support can be effectively improved, making it less prone to deformation.
[0018] Optionally, both the first side plate and the second side plate are provided with a plurality of first hollow areas arranged along the first horizontal direction, the first hollow areas being lower than the first limiting member, and both end plates are provided with second hollow areas.
[0019] By setting up hollow areas, the weight of the boat support can be effectively reduced, while also saving on the amount of boat support used in production and reducing costs.
[0020] Optionally, the first side plate, the second side plate, the two end plates, and at least one set of limiting parts are integrally formed.
[0021] The use of one-piece molding technology enables the rapid production of the boat support of this application, which is highly efficient.
[0022] Optionally, both ends of the first side plate and the second side plate are provided with protrusions that extend beyond the first end plate and the second end plate.
[0023] By setting up protrusions, the transport mechanism can easily grasp the boat support and transport it.
[0024] Optionally, the upper surfaces of both the first and second side plates include a planar area and an inclined area, with the planar area being connected to the upper surface of the limiting part through the inclined area.
[0025] By setting up a sloping area, the lugs of the silicon wafer boat can be guided, facilitating alignment during splicing.
[0026] Optionally, at least two pads are also provided at intervals on the outer edges of the lower surfaces of the first and second side plates.
[0027] By setting up pads, the boat support can be stably connected to the paddle's support groove when placed on the paddle, making it less prone to slippage.
[0028] Compared with the prior art, the beneficial effects of the technical solution of this application are:
[0029] This application provides a boat support, which avoids the adverse effect of reduced structural strength caused by opening a limiting groove in the side plate by setting a limiting part for limiting the silicon wafer boat on the inner side plate, thereby avoiding the occurrence of fracture accidents.

[0035] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0036] In the photovoltaic manufacturing industry, CVD (Chemical Vapor Deposition) is commonly used to coat silicon wafers. Currently, some manufacturers use a wafer carrier with positioning grooves on its upper surface to feed the silicon wafer boat into the CVD furnace for processing. The wafer boat is supported by lugs on both sides of its positioning grooves. However, the positioning grooves reduce the structural strength of the side plates, making them prone to breakage when supporting a large number of wafer boats.
[0037] To address this problem, this application provides a boat support, implemented in the following manner. The overall structure of the boat support provided by this application is as follows: Figure 1 As shown, the boat support includes a first side plate 11 and a second side plate 12, and two end plates 13. The first side plate 11 and the second side plate 12 both extend along a first horizontal direction (i.e., the length direction of the first side plate 11 and the second side plate 12). One end plate 13 is fixedly connected to the first end of the first side plate 11 and the second side plate 12, and the other end plate 13 is fixedly connected to the second end of the first side plate 11 and the second side plate 12. The boat support also includes at least one set of limiting parts 14, and the set of limiting parts 14 includes a first limiting member 141 and a second limiting member. The first limiting member 141 is disposed on the inner side of the first side plate 11 and located at the upper part, and the second limiting member is correspondingly disposed on the inner side of the second side plate 12 and located at the upper part. The positions of the first limiting member 141 and the second limiting member are correspondingly arranged.
[0038] As can be seen, the boat support of this application no longer needs to have a positioning groove, thereby avoiding the risk of breakage caused by the decrease in the strength of the side plate. The two lugs 10 of the silicon wafer boat are respectively mounted on the upper surfaces of the first side plate 11 and the second side plate 12. The limiting part 14 provided on the side plate provides a limiting function for the silicon wafer boat, preventing the silicon wafer boat from sliding along the first horizontal direction after being placed on the boat support.
[0039] Continue to refer to Figure 1 In one feasible embodiment, the first limiting member 141 may include at least one pair of adjacent first limiting members 1411 and second limiting members 1412, and a limiting gap can be formed between the paired first limiting members 1411 and second limiting members 1412. Both the first limiting members 1411 and second limiting members 1412 have a chamfered end near the limiting gap. The second limiting member has the same structure as the first limiting member 141. When the silicon wafer boat is placed on the boat support, the support ears 10 of the silicon wafer boat will sink into the limiting gap, thereby achieving limiting and preventing the silicon wafer boat from sliding along the first horizontal direction. The chamfers of the first limiting members 1411 and second limiting members 1412 can provide a guiding effect for the support ears 10 of the silicon wafer boat, making it easy for the support ears 10 to be aligned and sink into the limiting gap.
[0040] like Figure 2In one feasible embodiment, a silicon wafer boat has been placed on a boat support. The first limiting member 141 may include a plurality of third limiting blocks 1413, one of which is used to cooperate with a lug 10 on the silicon wafer boat to achieve limiting. Furthermore, the second limiting member has the same structure as the first limiting member 141, and the second limiting member limits the lug 10 on the other side of the same silicon wafer boat.
[0041] like Figure 3 In one feasible embodiment, the first limiting member 141 includes at least two strip plates 1414 that are spaced apart and extend along the circumferential support direction. The gap formed between two adjacent strip plates 1414 can be used to limit the lugs 10 on the silicon wafer boat. Specifically, when the silicon wafer boat is placed on the boat body, the lugs 10 of the silicon wafer boat can sink into the gap, and the two strip plates 1414 provide a limiting effect on them. Furthermore, the second limiting member has the same structure as the first limiting member 141.
[0042] In one feasible embodiment, the first limiting member 141 may also include a fourth limiting block. The upper surface of the fourth limiting block is provided with at least one limiting groove extending along a second horizontal direction for limiting the lugs 10 on the silicon wafer boat. The second horizontal direction is perpendicular to the first horizontal direction. The second limiting member has the same structure as the first limiting member 141. When the silicon wafer boat is placed on the boat support, the limiting groove can accommodate the lugs 10 of the silicon wafer boat, preventing the lugs 10 from sliding within the limiting groove, thus achieving limiting.
[0043] Furthermore, in order to facilitate the accurate entry of the support lug 10 of the silicon wafer boat into the limiting groove, the distance between the two side walls of the limiting groove is set to gradually decrease in the direction toward the bottom of the groove, thereby providing a guiding effect for the support lug 10.
[0044] It should be noted that the silicon wafer boat support 10 mentioned in this application has multiple embodiments and different structures, and can at least cooperate with the various embodiments of the first limiting member 141 and the second limiting member mentioned in this application to complete the limiting function. The limiting part 14 can at least provide a limiting function for the support 10 of the silicon wafer boat to prevent the silicon wafer boat from sliding along the side plate; at the same time, under the condition of high manufacturing precision, the limiting part 14 can also provide load-bearing for the support 10.
[0045] To improve the overall structural stability of the boat support, such as Figure 1 or Figure 2 The boat support also includes a connecting plate 15, the two ends of which are fixedly connected to the middle of the first side plate 11 and the second side plate 12, respectively, so that the boat body is not easily deformed.
[0046] In one feasible embodiment, in order to reduce the weight of the boat support, a first hollow area can be opened in the two side plates, and the first hollow area is set below the limiting part 14; and / or, the two end plates 13 can also be provided with a second hollow area to further reduce the weight of the boat support.
[0047] To facilitate production, the first side plate 11, the second side plate 12, the two end plates 13, and at least one set of limiting parts 14 can be integrally molded, resulting in higher production efficiency.
[0048] For ease of handling and picking up, such as Figure 1 and Figure 2 Both ends of the first side plate 11 and the second side plate 12 are provided with protrusions that protrude from the first end plate 13 and the second end plate 13, which facilitates picking up by robots, handling mechanisms, etc.
[0049] In one feasible embodiment, the upper surfaces of the first side plate 11 and the second side plate 12 both include a planar area and a sloped area. The planar area is connected to the upper surface of the limiting part 14 through the sloped area. The sloped area provides a guiding function for the support lugs 10 of the silicon wafer boat, which facilitates alignment during stacking.
[0050] In one feasible embodiment, such as Figure 2 As shown, at least two pads 16 are also provided at intervals on the outer edges of the lower surfaces of the first side plate 11 and the second side plate 12. When the boat support is placed on the paddle, each pad 16 abuts against the paddle to complete the overlapping placement, making it less likely to slip.
[0051] The foregoing has provided a sufficiently detailed and specific description of this application. Without conflict, the various embodiments described above can be combined arbitrarily as appropriate, and will not be exhaustively listed here. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of this application should fall within the protection scope of this application. The scope of protection claimed in this application is defined by the claims, not by the foregoing descriptions in the embodiments.
