Description

Technical Field

[0001] The present application relates to the field of battery cell drying technology, and in particular to a multi-channel battery cell drying device. Background Art

[0002] At present, crystalline silicon solar cells are still the most important photovoltaic products in domestic and foreign markets due to their low raw material costs and relatively mature technology. The metallization process of traditional crystalline silicon solar cells usually uses screen printing to print the corresponding conductive paste on the surface of the cell, and then dry and sinter to form electrode grid lines. Similarly, HJT cells also need to be dried and cured after the conductive paste is printed.

[0003] During the drying and curing process, the solar cells need to be transported to the furnace of the drying equipment. Existing drying equipment often uses a set of metal mesh chain rails to transport the solar cells. However, in the actual drying process, due to the large number of solar cells, the number of solar cells that can be transported by a set of metal mesh chains is limited, resulting in low drying efficiency.
