Description

Correcting device Technical Field The application relates to the technical field of battery production equipment, in particular to a correction device. Background With the advancement of dual-carbon strategy and the upgrading of photovoltaic industry technology, the passivation contact battery has become a mainstream technical route of industry by virtue of high conversion efficiency. In the production process of the silicon wafer, the graphite boat is used as a core tool for carrying the silicon wafer to carry out key processes such as chemical vapor deposition, front and back surface coating and the like, and the structural accuracy of the graphite boat directly determines the quality of the production process. The clamping piece on the graphite boat is used for supporting the silicon wafer so as to fix the silicon wafer to be clung to the boat blade.
