[0025] Specifically, the mounting groove 3 is used for inserting the end of the support rod 5, and the card slot 4 is used for inserting the chuck 6, so as to limit the support rod 5 laterally to prevent the support rod 5 from moving laterally and falling off. The support rod 5 is used to support the solar cell silicon wafer, and the separation and positioning baffle 7 can separate the solar cell silicon wafer, thereby preventing the solar cell silicon wafer from collapsing. By providing a plurality of mounting grooves 3, when two support rods 5 are inserted into the mounting grooves 3 with different spacings, the support spacing of the support rods 5 can be adjusted, and the corresponding support rods 5 can be replaced according to the different thicknesses of the solar cell silicon wafers, so that the spacing of the separation and positioning baffles 7 on the outer wall is consistent with the thickness of the solar cell silicon wafer, thereby achieving the effect of increasing the applicable surface of the boat support.

[0026] Reference Figure 3The fixing assembly 8 includes a plurality of extension rods 81, the outer wall of the extension rod 81 is tapped with a thread, the outer wall of the extension rod 81 is threadedly connected with a threaded cap 82, and the fixing assembly 8 also includes a plurality of arc-shaped slots 83, the slots 83 are opened on the outer side wall of the end plate 1, and the slots 83 are arranged on the outer side of the semicircle at the bottom end of the mounting groove 3;

[0027] Specifically, after the support rod 5 is placed, the threaded cap 82 is rotated to move it along the extension rod 81 until it is inserted into the slot 83, thereby fixing the support rod 5 to prevent the support rod 5 from shaking and affecting the supporting effect on the solar cell silicon wafer. By rotating the threaded cap 82, the support rod 5 can be quickly disassembled and assembled, achieving the effect of facilitating the replacement of the support rod 5.

[0028] Reference Figure 2 , an opening 9 is opened on the surface of the end plate 1, and a connecting plate 10 is fixedly connected to the lower side walls of the two end plates 1 symmetrically along the vertical center line;

[0029] Specifically, the opening 9 is used to facilitate the user to hold and carry the boat holder, and the connecting plate 10 is used to connect the two end plates 1.

[0030] Reference Figure 4 , the outer wall of the support rod 5 is installed with a reinforcement component 11, and the reinforcement component 11 includes a trapezoidal reinforcement seat 111. The outer walls of the reinforcement seat 111 on both sides are respectively connected to the reinforcement plate 112 by an axis rotation. The reinforcement seat 111 and the reinforcement plate 112 have a number of fixing grooves 113 on the opposite sides. The fixing grooves 113 are used to accommodate the support rod 5. The upper surface of the reinforcement seat 111 is symmetrically fixedly connected with a connecting seat 114. The surface of the connecting seat 114 is provided with a threaded groove 115. The upper surface of the reinforcement plate 112 is fixedly connected with a connecting seat 2 118. The surface of the connecting seat 2 118 is provided with a connecting hole 116. A bolt 117 is inserted into the connecting hole 116.

[0031] Specifically, the fixing groove 113 on the reinforcement seat 111 and the reinforcement plate 112 is used to accommodate the support rod 5, so that the reinforcement seat 111 and the reinforcement plate 112 can be engaged on the outside of the support rod 5, and are connected to the threaded groove 115 by bolts 117 to fix the reinforcement seat 111 and the reinforcement plate 112, so that the reinforcement seat 111 and the reinforcement plate 112 form a whole to reinforce the support rod 5, thereby improving the torsional or bending strength of the support rod 5 and effectively reducing its deformation risk at high temperatures.

[0032] Working principle: The two support rods 5 are placed in the fixing grooves 113 on both sides of the reinforcement seat 111, and then the reinforcement plate 112 is rotated upward so that the reinforcement plate 112 fits the reinforcement seat 111, and is connected to the threaded groove 115 through the bolt 117 passing through the connecting hole 116. The reinforcement seat 111 and the reinforcement plate 112 are fixed to the outer wall of the support rod 5, thereby reinforcing the support rod 5 through the reinforcement seat 111 and the reinforcement plate 112, improving the torsional or bending strength of the support rod 5, which can effectively reduce the risk of deformation under high temperature, enhance stability, reliability and service life, and insert the chuck 6 into the card slot 4 to laterally limit the support rod 5 to prevent it from falling off. By placing the solar cell silicon wafers between the two groups of separation and positioning baffles 7, the separation and positioning baffles 7 separate each group of solar cell silicon wafers, making it convenient to place them and preventing the solar cell silicon wafers from collapsing. The solar cell silicon wafers are supported by the support rod 5, which can avoid the bottom process airflow. The obstruction makes the upward flow of process gas more dispersed, allowing the process gas and silicon wafers to have more sufficient contact. According to the different thicknesses of solar cell silicon wafers, the support rod 5 with the spacing of the separating positioning baffle 7 with the same thickness can be replaced, so that it can be suitable for use with solar cell silicon wafers of different thicknesses. By rotating the threaded cap 82 and inserting it into the inside of the slot 83, the support rod 5 can be fixed to the bottom of the mounting groove 3, thereby preventing the support rod 5 from shifting, and the support rod 5 can be quickly disassembled and assembled. By replacing the support rod 5 and inserting it into the mounting grooves 3 with different spacings, this device can be suitable for placing solar cell silicon wafers of different thicknesses and sizes, and making the airflow have more sufficient contact with the solar cell silicon wafers. The support rod 5 can be quickly fixed by the fixing assembly 8, achieving the effect of convenient replacement of the support rod 5. The support rod 5 is reinforced at multiple points by the reinforcement assembly 11, thereby achieving the effect of improving the torsional or bending strength of the support rod 5 at high temperatures.
