Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] like Figure 1-4As shown, a photovoltaic quartz boat proposed in an embodiment of the utility model includes a quartz panel 1, a quartz rod 3 and a silicon wafer 4. The photovoltaic quartz boat designed in this scheme can be conveniently disassembled and assembled for use, and the overall applicable size can be adjusted to meet different use conditions. The quartz panel 1 is symmetrically arranged, and plug holes 2 are distributed on the quartz panel 1. Four quartz rods 3 are arranged between two quartz panels 1, and silicon wafers 4 are placed on the four quartz rods 3. One end of the quartz rod 3 is connected with a quartz limit head 5, and the quartz limit head 5 is arranged in cooperation with the plug hole 2. The quartz limit head 5 is connected to the quartz panel 1 cooperates with the friction setting. When the four quartz rods 3 need to be adjusted to place and use silicon wafers 4 of different sizes, the quartz limit head 5 is rotated, and the rotating column 501 is provided with frosting, which rubs against the rotating groove 304, and the rotation friction is large. In the case of no external force, the rotating column 501 remains stationary in the rotating groove 304 and will not be easily rotated and adjusted. By rotating the stopper 502 to keep it flush with the rectangular hole 202, the quartz column 303 at one end of the quartz rod 3 can be pulled out from the circular hole 201, and the pulled out quartz column 303 is plugged into the quartz panel by adjusting. 1, and then rotate the stopper 502 so that the stopper 502 abuts against the quartz panel 1 at the location of the plug hole 2. At this time, the stopper 502 is misaligned with the rectangular hole 202, so that the quartz limit head 5 can be used to abut against the quartz panel 1, so that the quartz rod 3 remains connected to the plug hole 2 and will not be separated from the quartz panel 1. The stopper 302 set at one end of the quartz column 303 will abut against the quartz panel 1 on the other side of the quartz limit head 5, ensuring that the quartz column 303 will not slide inside the circular hole 201, meeting the use requirements. The two ends of the quartz rod 3 are kept horizontally adjusted on the two quartz panels 1. Through the space formed by the four quartz rods 3, silicon wafers 4 of different sizes can be placed on the boat groove 301. Through the coordinated design, the quartz boat of this scheme can meet the adjustment and placement of silicon wafers 4 of different sizes, improve the overall applicability, and can achieve the effect of disassembling the quartz boat after the silicon wafer 4 is diffused, which is convenient for cleaning the quartz boat, improves the quality of the later diffusion processing of the silicon wafer 4, and meets the needs of the user. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

A rectangular hole 202 is provided on the quartz panel 1 at the location of the circular hole 201. The plug hole 2 can be connected with the quartz limit head 5 to ensure convenient disassembly and assembly.

[0024] like Figure 3As shown, in some embodiments, a plurality of boat grooves 301 are opened on the quartz rod 3 at equal intervals, and baffles 302 are fixedly connected to both ends of the boat groove 301. The baffles 302 are fixedly connected to the quartz column 303. A rotating groove 304 is opened on the quartz column 303. The quartz column 303 is plugged into the circular hole 201. The design of the quartz rod 3 meets the requirements of placing the silicon wafer 4 and adjusting the use requirements.

[0025] like Figure 4 As shown, in some embodiments, the quartz limit head 5 is composed of a rotating column 501 and a stop head 502. The stop head 502 is fixedly connected to the rotating column 501. The rotating column 501 is rotatably connected in the rotating groove 304. The stop head 502 is matched with the rectangular hole 202. The quartz limit head 5 meets the needs of convenient plug-in adjustment inside the plug-in hole 2, and can make the quartz rod 3 conveniently adjusted and disassembled for use on the two quartz panels 1.
