[0033] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that, for the sake of convenience of description, only some parts related to the present utility model are shown in the drawings, rather than all the structures.

The first feature being "below", "below the bottom of", and "under the bottom of" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0036] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0037] The present utility model discloses a support clamping point 100. Refer to Figures 1 - 3 As shown, the support clamping point 100 is used to be installed on the boat piece 200. The support clamping point 100 has a first installation section 110. A plurality of protruding portions 111 are arranged on the outer surface of the first installation section 110 along its circumferential direction. An installation space 112 is formed between two adjacent protruding portions 111. The sheet material 10 is received in the installation space 112. It can be understood that since a plurality of protruding portions 111 are provided on the support clamping point 100, an installation space 112 is formed between two adjacent protruding portions 111, and the sheet material 10 is received in the installation space 112, so that the number of installation spaces 112 on the support clamping point 100 is multiple. When a problem occurs in one of the installation spaces 112, another installation space 112 can be selected to install the sheet material 10, which prolongs the service life and replacement frequency of the support clamping point 100 and is beneficial to cost reduction.

[0038] In some embodiments, the sidewall of the installation space 112 abuts against the sheet 10. Thus, the supporting effect of the supporting clamping point 100 on the sheet 10 can be improved, ensuring the stability of the sheet 10.

[0039] In some embodiments, the protrusion 111 is a thread, and an installation space 112 is formed between two adjacent threads. The sheet 10 is received in the installation space 112. It can be understood that the protrusion 111 is a thread, which can support the sheet 10 from falling and can also hold the sheet 10 through the thread lines to prevent the sheet 10 from tipping over. Compared with the clamping points in the prior art, the size of the supporting clamping point 100 with threads can be made smaller, only ensuring that the thread pitch is greater than the thickness of the sheet 10. The sheet 10 will be stuck into the thread by its own gravity. The height of the thread is very small, minimizing the area blocking the process gas as much as possible, reducing the area of the clamping point impression on the sheet 10, and thus improving the efficiency of the solar cell to convert solar energy into electrical energy per unit area.

[0040] In some specific embodiments, the angle of the thread is 30° - 120°. The angle of the thread can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, or other values within the range of 30° - 120°. Controlling the angle of the thread within 30° - 120° is beneficial to reducing the area blocking the process gas, reducing the area of the clamping point impression on the sheet 10, and thus improving the efficiency of the solar cell to convert solar energy into electrical energy per unit area.

[0041] In some specific embodiments, the diameter of the thread is 0.08 mm - 3 mm. The diameter of the thread here refers to the major diameter of the thread. Optionally, the diameter of the thread can be 0.08 mm, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm. The diameter of the thread can also be other numbers between 0.08 mm and 3 mm, not limited to the above examples. It can be understood that the diameter of the existing clamping points is usually about 6 mm. In this embodiment, since the thread can be stably inserted into the sheet 10, the diameter of the thread in the range of 0.08 mm - 3 mm can stably support the sheet 10. Compared with the clamping points in the prior art, the supporting clamping point 100 in this embodiment greatly reduces the area of the clamping point impression on the sheet 10, and thus improves the efficiency of the solar cell to convert solar energy into electrical energy per unit area.

[0042] In an alternative embodiment, the protrusion 111 is a convex ring, and a plurality of convex rings are provided on the first mounting section 110 at intervals along its axial direction. An installation space 112 is formed between two adjacent convex rings. The heights of the plurality of convex rings can be the same or different, and can be selected according to actual needs. The convex ring can be a structure with a constant cross-sectional area, or a wedge shape with a gradually decreasing cross-sectional area in the direction away from the first mounting section 110.

[0043] Of course, in other embodiments of the present utility model, the form of the protrusion 111 can also be selected according to actual needs, and is not limited to the above limitations.

[0044] In some embodiments, as shown in Figure 2 the support locking point 100 further has a second mounting section 120 connected to the first mounting section 110. The second mounting section 120 is used to be mounted on the boat piece 200, and the first mounting section 110 is located on the side of the second mounting section 120 away from the boat piece 200. It can be understood that the second mounting section 120 can ensure the stable cooperation between the support locking point 100 and the boat piece 200, so as to ensure that the sheet 10 can be stably supported on the boat piece 200.

[0045] In some specific embodiments, the second mounting section 120 is threadedly connected to the boat piece 200. It can be understood that when the second mounting section 120 is threadedly connected to the boat piece 200, if the installation space 112 for accommodating the sheet 10 currently wears out, the second mounting section 120 can be rotated to select a new installation space 112 between two protrusions 111 to accommodate the sheet 10, without replacing the entire support locking point 100, thereby reducing costs.

[0046] In some specific embodiments, there are two first mounting sections 110, and the two first mounting sections 110 are respectively connected to both sides of the second mounting section 120 along its axial direction. Thus, after the support locking point 100 is mounted on the boat piece 200, the two first mounting sections 110 are respectively connected to both sides of the second mounting section 120 along its axial direction, realizing that both relatively arranged sides of the boat piece 200 can support the sheet 10, improving the sheet loading capacity of the boat piece 200, and thus being beneficial to improving the process efficiency.

[0047] In an alternative embodiment, the support locking point 100 only includes the first mounting section 110, and the protrusion 111 is a thread. During the actual installation process, since the thickness of the boat piece 200 is relatively small, the support locking point 100 can be rotated and screwed into the mounting hole on the boat piece 200, similar to the tapping process in machining. Thus, the support locking point 100 can also be conveniently and stably mounted on the boat piece 200.

[0048] In some embodiments, chamfers are provided at both axial ends of the support clamping point 100. It can be understood that the chamfers facilitate the insertion of the support clamping point 100 into the boat piece 200, thus facilitating the installation of the support clamping point 100.

[0049] In some embodiments, the support clamping point 100 is a graphite piece. It can be understood that since the boat piece 200 is usually a graphite piece, selecting a graphite piece for the support clamping point 100 can avoid scratching the boat piece 200 when installing the support clamping point 100, which is beneficial to protecting the boat piece 200.

[0050] The present utility model also discloses a support mechanism, which includes a boat piece 200 and the aforementioned support clamping point 100. A plurality of bearing positions 210 are arranged at intervals along the length direction of the boat piece 200, and each bearing position 210 is provided with a corresponding plurality of support clamping points 100. Due to the support clamping point 100 described above, and a plurality of protrusions 111 are provided on the support clamping point 100, an installation space 112 is formed between two adjacent protrusions 111, and the sheet material 10 is received in the installation space 112, so that the number of installation spaces 112 on the support clamping point 100 is multiple. When a problem occurs in one installation space 112, another installation space 112 can be selected to install the sheet material 10, which prolongs the service life and replacement frequency of the support mechanism and is beneficial to reducing costs.

[0051] In some embodiments, each bearing position 210 is provided with three support clamping points 100. One support clamping point 100 is located below the bearing position 210, and two support clamping points 100 are located outside two opposite side walls of the bearing position 210. It can be understood that the sheet material 10 can be fixed by the three support clamping points 100, so as to ensure that the sheet material 10 can be stably held at the bearing position 210 to facilitate the process and is beneficial to improving the process yield.

[0052] In some specific embodiments, among the two support clamping points 100 located on the side of the bearing position 210, one support clamping point 100 is arranged close to the bottom wall of the bearing position 210, and the other support clamping point 100 is arranged close to the top wall of the bearing position 210. It can be understood that during the actual process of inserting the sheet, two adjacent side walls of the sheet material 10 respectively abut against the support clamping point 100 located below the bearing position 210 and the support clamping point 100 arranged close to the bottom wall of the bearing position 210, so as to ensure that the sheet material 10 is inclined and held on the boat piece 200 to facilitate the process and is beneficial to improving the process yield. The other support clamping point 100 arranged close to the top wall of the bearing position 210 can prevent the sheet material 10 from rotating, thereby further ensuring the stability of the sheet material 10.

[0053] In some specific embodiments, bearing positions 210 are provided on both relatively arranged sides of the boat piece 200. The support clamping point 100 penetrates through the boat piece 200, and one support clamping point 100 is used to support two sheets 10 located at the bearing positions 210 on the relatively arranged sides of the boat piece 200. Thus, both relatively arranged sides of the boat piece 200 can support the sheet 10, improving the sheet loading capacity of the boat piece 200, which is beneficial to improving the process efficiency.

[0054] The present utility model also discloses a support carrier. Refer to Figure 4 As shown, it includes a plurality of the foregoing support mechanisms and a connection component 300. The plurality of support mechanisms are arranged at intervals, and the connection component 300 is used to connect the plurality of support mechanisms. Since it has the support mechanism described above, and a plurality of protrusions 111 are provided on the support clamping point 100 of the support mechanism, an installation space 112 is formed between adjacent two protrusions 111, and the sheet 10 is received in the installation space 112, so that the number of installation spaces 112 on the support clamping point 100 is multiple. When a problem occurs in one installation space 112, another installation space 112 can be selected to install the sheet 10, extending the service life and replacement frequency of the support mechanism, which is beneficial to reducing costs.

[0055] Optionally, refer to Figures 4 - 5 As shown, the connection component 300 includes an insulating rod 310, an insulating sleeve 320, a first gasket 330 and a first nut 340. The insulating rod 310 penetrates through a plurality of boat pieces 200, the insulating sleeve 320 is sleeved on the insulating rod 310 and clamped between adjacent two boat pieces 200, the first nut 340 is connected to both sides of the insulating rod 310, and the first gasket 330 is clamped between the first nut 340 and the boat piece 200. It can be understood that the insulating rod 310 and the insulating sleeve 320 connect a plurality of boat pieces 200 together, ensuring the structural stability of the support carrier. The first nut 340 can play a locking role to prevent the boat piece 200 from being conveyed along the axial direction of the insulating rod 310, and the first gasket 330 can prevent the first nut 340 from scratching the sheet 10. Optionally, the insulating rod 310, the insulating sleeve 320, the first gasket 330 and the first nut 340 are all ceramic parts.

[0056] Optionally, refer to Figures 4 - 5 As shown, boat ears 220 are provided at both ends of the boat piece 200. The plurality of boat pieces 200 are divided into two groups, and the boat ears 220 of the two groups of boat pieces 200 are staggered, and the two groups of boat pieces 200 are arranged in an interleaved manner. That is, the boat ears 220 of adjacent two boat pieces 200 are staggered, and the boat pieces 200 of two alternately arranged boat pieces 200 are relatively arranged. The support carrier further includes a conductive block 400 clamped between two relatively arranged boat ears 220. It can be understood that through the arrangement of the conductive block 400, a plurality of boat pieces 200 can be conducted, facilitating external connection of electrodes.

[0057] Optionally, referring to Figures 4 - 5 as shown, electrode holes 410 are provided on the conductive block 400. The electrode holes 410 are used to externally connect electrodes. Thus, it facilitates the connection between the support carrier and the electrodes, thereby facilitating the process. Support feet 420 are also provided on the conductive block 400. Thus, it facilitates the cooperation between the support carrier and the support rod in the process chamber, thereby ensuring that the entire support carrier can be stably placed in the process chamber.

[0058] Referring to Figures 4 - 5 as shown, the support carrier further includes a conductive assembly 500. The conductive assembly 500 is used to fix the boat ears 220 and the conductive block 400. The conductive assembly 500 includes conductive rods 510, second gaskets 520, and second nuts 530. Each conductive rod 510 passes through a set of boat ears 220 and the corresponding conductive block 400. The second nuts 530 are connected to both ends of the conductive rod 510. The second gaskets 520 are clamped between the conductive block 400 and the second nuts 530. The added conductive rods 510 can ensure the connection stability between multiple conductive blocks 400 and the boat ears 220. The second nuts 530 can prevent the conductive block 400 from axially moving along the conductive rod 510. The second gaskets 520 can prevent the second nuts 530 from scratching the conductive block 400.
