[0002] Solar photovoltaic cells are a new type of cell that converts sunlight directly into electrical energy. Currently, silicon photovoltaic cells based on silicon are commonly used, including single-crystal silicon, polycrystalline silicon and amorphous silicon photovoltaic cells. In the preparation process of solar photovoltaic cells, silicon wafers need to go through processes such as texturing, diffusion, etching, coating and printing in sequence. Quartz boat is a commonly used wafer carrier.

[0003] The quartz boat comprises panels (13) on both sides, a first slot rod (14) symmetrically arranged at the bottom and a second slot rod (15) symmetrically arranged at the top, the first slot rod (14) having a first slot opening (16) evenly arranged on the inner side, and the second slot rod (15) having a second slot opening (17) evenly arranged on the inner side.

[0004] The quartz boat needs to be tested for symmetry, which requires that the center axes on both sides of the side panels be coaxial with the center axis of the lower bell mouth. However, there is currently no suitable measuring tool to test the coaxiality, and manual testing is required. However, there are many uncertain factors in the manual testing process, which can easily lead to inaccurate test results. Utility Model Content

If the panels on both sides of the quartz boat can just fit on the first positioning plate and the second positioning plate, and the insert (similar to a silicon wafer) is vertically inserted between the first slot rod and the second slot rod (close to the detection plate), the insert can be inserted and the distance between the insert and the detection plate is less than 1mm, which means that the symmetry of the quartz boat meets the requirements; during the entire detection process, workers do not need to perform manual measurements, but instead perform detection through the fixed first positioning plate, the second positioning plate and the detection plate to avoid interference from external factors, thereby improving the accuracy of detection.

[0017] 2. By providing a plurality of third positioning plates, the position of the third positioning plates can be set according to existing quartz boats of different lengths, thereby being able to adapt to the detection of symmetry of quartz boats of different sizes and improving the versatility of the inspection tool.
