[0002] The cell coating equipment uses silicon carbide paddles to support the graphite boat loaded with cells to extend into the coating furnace tube. During the insertion process, the motor hole on the graphite boat needs to be aligned with the electrode rod on the flange at the end of the coating furnace tube.
[0003] Due to the continuous increase in production capacity demand, the number of battery cells loaded on the graphite boat needs to increase, and the full load weight of the graphite boat also increases accordingly. The silicon carbide paddle of the coating equipment in the related technology is prone to bending or even breaking when the heavy fully loaded graphite boat is supported on the silicon carbide paddle.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0028] The silicon carbide paddle support structure 1 according to an embodiment of the present utility model is described below with reference to the accompanying drawings.
[0029] like Figure 1-Figure 4 As shown, the silicon carbide paddle support structure 1 according to an embodiment of the present utility model includes a paddle seat 10 , a silicon carbide paddle 20 and a support rod 30 .
[0030] The silicon carbide paddle 20 is connected to the paddle seat 10 , and the silicon carbide paddle 20 is tubular. The support rod 30 is fitted in the silicon carbide paddle 20 , and the rigidity of the support rod 30 is greater than that of the silicon carbide paddle 20 .
[0031] Specifically, in the coating process, such as Figure 2-Figure 4 As shown, after the graphite boat 2 is loaded with battery cells, it is placed on the silicon carbide paddle 20. The graphite boat 2 is supported on the silicon carbide paddle 20 by the boat feet 3. Then, the silicon carbide paddle 20 and the graphite boat 2 are extended into the coating furnace tube 5 so that the electrode rod 6 on the flange of the coating furnace tube 5 fits into the electrode hole 4 on the graphite boat 2.
[0032] The silicon carbide paddle in the related art is prone to bending or even breaking when the weight of the graphite boat loaded with battery cells is heavy, making it difficult to align the electrode holes on the graphite boat with the electrode rods, causing the electrode rods to hit the graphite boat, causing the graphite boat to tip over or even fall, resulting in damage to the graphite boat and the battery cells.
[0033] According to the silicon carbide paddle support structure 1 of the embodiment of the utility model, by fitting a support rod 30 having a stiffness greater than that of the silicon carbide paddle 20 into the silicon carbide paddle 20, compared with the silicon carbide paddle in the related art that lacks support, the support rod 30 can be used to support the silicon carbide paddle 20 to prevent the silicon carbide paddle 20 from bending and breaking, thereby ensuring the stability and reliability of the graphite boat 2 on the silicon carbide paddle 20, making the positioning of the silicon carbide paddle 20 and the graphite boat 2 more accurate, facilitating the alignment of the electrode hole 4 of the graphite boat 2 with the electrode rod 6 of the coating furnace tube 5, and avoiding collision between the electrode rod 6 and the graphite boat 2.
[0034] Furthermore, by arranging the support rod 30 inside the silicon carbide paddle 20, it is possible to prevent the support rod 30 from interfering with the normal use of the silicon carbide paddle 20. Compared with the related art method of increasing the supporting force by increasing the number of silicon carbide paddles, not only is the supporting effect better, but there is no need to increase the number of silicon carbide paddles, which can facilitate control of the overall cost.
[0035] Therefore, the silicon carbide paddle support structure 1 according to the embodiment of the utility model has the advantages of good supporting effect, stable and reliable, accurate positioning, and low cost.
[0036] The silicon carbide paddle support structure 1 according to a specific embodiment of the utility model is described below with reference to the accompanying drawings.
[0037] In some specific embodiments of the present invention, Figure 1-Figure 4 As shown, the silicon carbide paddle support structure 1 according to an embodiment of the present utility model includes a paddle seat 10 , a silicon carbide paddle 20 and a support rod 30 .
[0038] Advantageously, if Figure 1As shown, one end of the support rod 30 close to the paddle seat 10 extends out of the silicon carbide paddle 20 and is connected to the paddle seat 10. In this way, the support rod 30 can also be connected to the paddle seat 10, further improving the supporting effect of the support rod 30 on the silicon carbide paddle 20, and further preventing the silicon carbide paddle 20 from bending and breaking.
[0039] Alternatively, if Figure 1-Figure 3 As shown, there are two silicon carbide paddles 20, and two support rods 30 are respectively fitted in the two silicon carbide paddles 20. In this way, the two silicon carbide paddles 20 can be used to jointly support the graphite boat 2, thereby improving the stability of the graphite boat 2. By providing two support rods 30, the two silicon carbide paddles 20 can be supported by the two support rods 30, respectively, thereby ensuring that both silicon carbide paddles 20 can be effectively supported.
[0040] Specifically, Figure 1 As shown, the propeller seat 10 has a connecting column 11, and a support rod connecting bracket 31 is provided on the connecting column 11, and the support rod connecting bracket 31 is respectively connected to two support rods 30. In this way, it is convenient to connect the two support rods 30 to the propeller seat 10, thereby improving the stability and reliability of the silicon carbide propeller support structure 1.
[0041] Specifically, the connecting column 11 is located between the two support rods 30. This can make the force on the support rods 30 more uniform, making the silicon carbide paddle support structure 1 more stable and reliable.
[0042] More specifically, Figure 1 As shown, a plurality of silicon carbide paddle connection brackets 21 are provided on the connection column 11, and the plurality of silicon carbide paddle connection brackets 21 are arranged at intervals along the length direction of the connection column 11, and each silicon carbide paddle connection bracket 21 is respectively connected to two silicon carbide paddles 20, and a plurality of connection pipe clamps 22 are further connected between the two silicon carbide paddles 20, and the plurality of connection pipe clamps 22 are arranged at intervals along the length direction of the silicon carbide paddles 20. This can facilitate the connection between the silicon carbide paddle 20 and the paddle seat 10, and further improve the stability and reliability of the silicon carbide paddle support structure 1.
[0043] Furthermore, if Figure 2 As shown, the support rod 30 is loosely fitted in the silicon carbide paddle 20. Specifically, the inner diameter of the silicon carbide paddle 20 may be 30 mm, and the outer diameter of the support rod 30 may be 29 mm. This makes it easier to install the support rod 30 in the silicon carbide paddle 20.
[0044] Furthermore, if Figure 1 , Figure 3 and Figure 4As shown, the length of the support rod 30 is greater than the length of the silicon carbide paddle 20. Specifically, the length of the silicon carbide paddle 20 is 2200-2300 mm, and the length of the support rod 30 can be 2400-2600 mm. Here, it is preferred that the length of the silicon carbide paddle 20 is 2266 mm, and the length of the support rod 30 is 2500 mm. This can not only ensure the support effect of the support rod 30 on various parts of the silicon carbide paddle 20, but also facilitate the support rod 30 to extend from the silicon carbide paddle 20 to be connected to the paddle seat 10.
[0045] Figure 2 The silicon carbide paddle support structure 1 according to some examples of the present invention is shown. Figure 2 As shown, the support rod 30 is in a hollow tubular shape, which can reduce the weight of the support rod 30, reduce the influence of the setting of the support rod 30 on the load of the silicon carbide paddle 20, and further avoid the silicon carbide paddle 20 from bending and breaking.
[0046] Optionally, the wall thickness of the support rod 30 is 1-3 mm. Here, the wall thickness of the support rod 30 is preferably 2 mm. In this way, the weight of the support rod 30 can be reduced while ensuring the structural strength and rigidity of the support rod 30 to ensure the supporting effect of the support rod 30.
[0047] Furthermore, the support rod 30 is made of stainless steel, which can ensure the structural strength and rigidity of the support rod 30 and thus ensure the supporting effect of the support rod 30.
[0048] Other structures and operations of the silicon carbide paddle support structure 1 according to the embodiment of the utility model are known to ordinary technicians in the field and will not be described in detail here.
