[0002] Currently, the diffusion, oxidation, doping, and coating processes in solar cell production require temperatures of 700-1050°C, all of which require the use of quartz tubes as carriers. The average service life of quartz tubes is approximately 30-60 days. With the continuous evolution of production equipment and products, the number and size of quartz tubes used have increased. Quartz tube replacement has always been a critical maintenance task for solar cell production equipment.

[0003] The average length of existing quartz tubes is 3.9-4.2 meters, the diameter is 460-480 mm, and the weight is 80-100 kg. Furthermore, due to their fragile nature, they are currently replaced manually, requiring an average of 4-6 people and 2-3 hours to replace each tube, significantly increasing maintenance resources.
