[0020] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following embodiments are provided in conjunction with the appendix. Figure 1 To be continued Figure 3 The technical solution provided by this utility model is described in detail, but the following content is not intended to limit this utility model.

[0021] Figure 1 This is a structural diagram from one perspective of an embodiment of a carbon boat according to the present invention; Figure 2 This is a structural diagram from another perspective of an embodiment of the carbon boat of this utility model; Figure 3 This is a structural diagram from another perspective of an embodiment of the carbon boat of this utility model. (See diagram below.) Figure 1 , Figure 2 as well as Figure 3As shown, the carbon-carbon boat provided by the embodiment comprises a plurality of boat pieces 1, a plurality of partition blocks 2, a plurality of graphite rods 3, a plurality of clamping points 5 and a plurality of ceramic tubes 4. The plurality of boat pieces 1 are divided into left electrode pieces and right electrode pieces. During installation, the plurality of left electrode pieces and the plurality of right electrode pieces are alternately and spacedly arranged. One end of each of the plurality of left electrode pieces and the plurality of right electrode pieces is provided with a partition block 2 between two adjacent pieces. The plurality of left electrode pieces and the corresponding plurality of partition blocks 2 are arranged on and locked to one set of graphite rods 3, and the plurality of right electrode pieces and the corresponding plurality of partition blocks 2 are arranged on and locked to another set of graphite rods 3. The same-polarity boat pieces 1 are connected by the partition blocks 2 and the corresponding graphite rods 3 to meet the film plating requirement. In addition, the plurality of ceramic tubes 4 are arranged between two adjacent boat pieces 1 to isolate and support the two adjacent boat pieces 1. Furthermore, the plurality of clamping points 5 are arranged on each boat piece 1 to support and fix the solar silicon wafer to be plated.

[0022] Specifically, the material of each boat piece 1 is carbon fiber, i.e., each boat piece 1 is made of carbon fiber material, so that the obtained boat piece 1 has better oxidation resistance and corrosion resistance, higher bending strength, and can extend the service life of the boat piece 1 by several times, thereby reducing the use cost. In addition, based on the stable chemical properties and high-strength bending resistance of the carbon fiber material, the use requirement can still be met when the thickness of the boat piece 1 is reduced, so that more boat pieces 1 can be arranged in a limited space, thereby increasing the film plating station, allowing more solar silicon wafers to be placed, and further improving the production capacity. Furthermore, the boat piece 1 made of carbon fiber material has lower density than the boat piece 1 made of existing graphite material, so that the total weight of the obtained boat is lighter, thereby reducing the load of the main machine table boat paddle, reducing the risk of overloading and bending, prolonging the service life, and also allowing the use of a boat paddle with lighter carrying capacity to replace the original boat paddle with strong carrying capacity, effectively reducing the use cost and making the structure design more reasonable.

[0023] More specifically, after the plurality of boat pieces 1, partition blocks 2, graphite rods 3, ceramic tubes 4 and clamping points 5 form an overall boat structure, the thickness of the boat piece 1 located at the outermost side is greater than the thickness of the boat piece 1 located at the inner side, so that the structural strength of the boat piece 1 located at the outermost side is further improved, the external protection capability is improved, the risk of structural damage during use is reduced, and the service life is prolonged.

[0024] More specifically, the thickness of the outermost boat piece 1 of the assembled boat structure is in the range of 0.5-3mm, while the thickness of the inner boat piece 1 is in the range of 0.5-2.5mm, preferably, the thickness of the outermost boat piece 1 is 2.5mm, and the thickness of the inner boat piece 1 is 1.3mm, which can reduce the thickness of the outermost and inner boat piece 1 to the greatest extent while ensuring the structural strength and meeting the use requirements, so that the number of boat pieces 1 is increased, and the production capacity is higher than that of the existing graphite boat.

[0025] More specifically, the distance between the two adjacent boat pieces 1 is in the range of 8-15mm, preferably, the distance between the two adjacent boat pieces 1 is 11mm, which can meet the normal solar silicon wafer placement and coating requirements while avoiding space waste, and the structural design is more reasonable.

[0026] More specifically, the spacer 2 is also provided with a hollow hole 21, which not only reduces the weight of the spacer 2, but also further reduces the overall weight of the boat, and further reduces the load of the main machine table boat slurry. In addition, the hollow hole 21 reduces the heat absorption of the material, so that the heating time required in the coating heating process is less, that is, the process time is reduced, thereby improving the production efficiency and reducing the production cost.

[0027] More specifically, a plurality of inner frame holes 11 are formed on the inner boat piece 1, and the solar silicon wafer to be coated is placed in the inner frame hole 11 during coating to meet the coating requirements. At this time, each inner frame hole 11 is a rectangular hole, and the width of the inner frame hole 11 is in the range of 137-157mm, and the length of the inner frame hole 11 is in the range of 152-187mm, which can ensure that the solar silicon wafer can be normally coated while ensuring the structural strength and use requirements of the boat piece 1.

[0028] As a preferred embodiment, the width and length of the inner frame hole 11 on the inner boat piece 1 are respectively selected as 147mm and 162mm, which is smaller than the original width and length of the inner frame hole 11, which are respectively 157mm and 187mm, while ensuring the effect of the coating process, thereby effectively reducing the area of the inner frame hole 11, so that the contact area of the solar silicon wafer and the boat piece 1 is larger, that is, the supporting contact surface of the boat piece 1 to the solar silicon wafer is increased, and the supporting effect is better, so that the solar silicon wafer can be sufficiently supported without being deformed when the boat is placed into the furnace tube for vacuumizing operation, thereby avoiding scratching of the solar silicon wafer and ensuring the processing quality and product quality.

[0029] The carbon-carbon boat provided by the embodiment comprises a boat piece 1, a partition block 2, a graphite rod 3, a clamping point 5 and a ceramic tube 4; the boat piece 1 is made of carbon fiber material, which meets the electric conductivity and has better oxidation resistance, corrosion resistance and bending strength, effectively prolongs the service life of the boat piece 1, reduces the use cost, and further reduces the thickness of the boat piece 1 under the condition of ensuring the structural strength, so that more boat pieces 1 are arranged in the effective space, the placing station of the solar silicon wafer is increased, the production capacity is improved, and the carbon fiber material has smaller density compared with the traditional graphite material, so that the total weight of the boat is reduced, the load of the main machine is lighter, the overload bending problem is not prone to occur, the service life is further prolonged, and the boat paddle with lighter carrying capacity can be replaced under the same use environment, and the use cost is further reduced.

[0030] The above is only the preferred embodiment of the utility model, and does not limit the implementation and protection scope of the utility model; for those skilled in the art, it should be realized that the scheme obtained by equivalent replacement and obvious changes of the utility model specification and drawings should be included in the protection scope of the utility model.
