Description

Technical Field

[0001] The utility model belongs to the technical field of conveying equipment, and in particular relates to a cell sheet transmission device in high-temperature equipment of a photovoltaic cell production line. Background Art

[0002] At present, the high-temperature sintering function on the photovoltaic cell production line can be summarized as follows: at high temperature, the slurry printed on the cell by the silk-screen process is oxidized and decomposed, and the metal particles in the slurry are sintered into wires that are well fused and in contact with the silicon crystal. This sintering process requires the cell to pass through high-temperature equipment. There are two main ways to transport the cell in the furnace: one is a metal mesh belt and its improved version (chain and chain plate), where the cell is lifted by the pins on the mesh belt and moves forward with the mesh belt; the other is a ceramic (or glass) roller conveyor. The roller rotates at a fixed position, and a ceramic ring is fixed on the roller. The truncated bevel of the ceramic ring contacts the edge of the cell, and the cell moves forward by the friction between the two.

[0003] These two methods have their own advantages and disadvantages: 1) The mesh belt or chain method is not energy-saving. The mesh belt or chain must complete the rotation outside the furnace, taking away a considerable amount of heat (compared with the battery cell, its mass is very large). And the ejector pins that lift the battery cell will form "imprints" on the battery cell, affecting product performance. Its advantage is that there is no relative movement or friction between the mesh belt and the battery cell, the transmission is stable, and it is not easy to produce fragments; 2) The ceramic roller and magnetic ring conveying method is energy-saving, but a small amount of slurry printed in the previous process of the battery cell will adhere to the ceramic roller. Under high temperature conditions, the adhered slurry will be sintered into irregular convex objects (bumps) on the magnetic ring, changing the rotation radius of the magnetic ring, causing the battery cell to deviate and break.
