The graphite boat, as a carrier during the deposition of anti-reflection films on solar cells, its structure and size directly affect the conversion efficiency and production efficiency of silicon wafers.

[0004] After the graphite boat is used for a period of time, the boat plates will become loose, and the surface of the boat plates will be covered with dust, affecting the efficiency of the graphite boat. Therefore, the graphite boat will be disassembled, the boat plates will be purged and cleaned of dust, and damaged accessories such as nuts, ceramic rings, and clamping points will be replaced. After replacing the accessories and calibration, the graphite boat plates will be assembled and applied again.

[0005] The existing disassembly and assembly of graphite boats use independent mechanical equipment in cooperation with manual labor to complete disassembly and assembly, with relatively low efficiency, and the various equipment is scattered and occupies a large area.

[0072] Working principle: The graphite boat is loaded onto the loading and unloading turnover mechanism 10. The graphite boat rotating handling mechanism 4 rotates the graphite boat on the loading and unloading turnover mechanism 10 by 90° and then transports it to the graphite boat disassembly and assembly component 5 for disassembling nuts, ceramic rings, and electrode blocks. The graphite boat piece handling mechanism 11 sequentially adsorbs the boat pieces and places them into the graphite boat piece transmission device 9 for transportation to the boat piece temporary buffer mechanism 8. After being detected by the clamping point machine and having the clamping points replaced, it is sent back to the graphite boat disassembly and assembly component 5 for assembly. The assembled graphite boat is then sent to the loading and unloading turnover mechanism 10 for unloading.

[0073] During this process, scrapped boat pieces, nuts, and ceramic rings are automatically replaced.

[0074] The whole process has a high degree of automation. The two groups of graphite boat disassembly and assembly components 5 work alternately, and the disassembly and assembly are completed integrally, greatly improving the efficiency of graphite boat piece calibration and replacement of accessories. The structure is compact and occupies a small area.

[0075] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0076] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
